The invention relates to intake devices designed to prevent the ingress of impurities in the water conveyance network, such as devices that provide a fence of sticks and flow into the irrigation network of such liquids as livestock effluents.

Known filter for water purification, comprising a housing with an inlet and outlet that is installed in the rotating perforated filter element and camera trapping impurities [1].

The disadvantage of this filter is that to achieve efficient operation it is made rotatable, which requires additional actuator, i.e. additional energy consumption. In addition, the holes (perforation) mesh filter element clogged long fibrous impurities, such as remnants of food that fall in livestock wastewater. This reduces the reliability of the filter.

Also known intake device comprising a housing with an inlet and outlet, mounted perforated filter element made in the form of a cylinder installed in the holes of perforated curved tubes, the free end of each of which is located in the direction of the main flow, the body is made in the form of a truncated cone with a large base at the entrance and is equipped with raspolozhennymi the input and output apertures of diaphragm valves, and the camera trapping impurities placed between the filter element and the walls of the shell [2].

The intake device includes a housing in which is installed a filter element made in the form of a cylinder. The cylinder is connected to the suction pipe of the pump. In the cylinder wall with holes in which is rigidly fixed filter curved tube. The free end of the tube outside of the cylinder, is installed in the direction along the main stream of fluid, and the other is introduced into the cylinder.

The case is equipped located in the input and output apertures of diaphragm valves. The liquid flows through the inlet valve in filter mode, and through the exhaust valve in the reverse flushing.

The famous water intake device in filter mode liquid from the receiver is fed through the exhaust valve in the annular cavity, passes through the filtering curved tubes and the cylinder into the suction pipe. At this time the exhaust valve is closed.

Large solid impurities in the liquid, cover the inlet tube, and fibrous impurities accumulate on the walls of the tubes.

In the case of significant clogging of the filter pump off. Water return flows from the suction pipe into the filter tube and removes the impurities. is this moment in the annular cavity pressure increases, in the result, the inlet valve closes and the exhaust valve opens, and impurities from the camera are fed into the collection.

Lack of water intake device is that in the process of filtering curved tube clogged solid and long fibrous impurities.

Water is fed into the suction pipe of the pump. When this force sucked hard and long staple impurities in the liquid several times more than the pressure of the water entering the reverse flow from the pipeline into the filter elements. So part of the filter tubes, clogged solid and long fibrous impurities, not cleaned water back flow from the suction pipe into the filter tube. Poor cleaning of the filter tubes from solid and fibrous impurities due to the fact that the size of the cross section of the tubes when cleaning is not increased.

As a result, reduced the reliability of the filter element

In addition, the number, the size of suspended particles and particulate matter contained in the effluents and prepared animal waste must meet the technical requirements of pumps, pipelines and irrigation equipment.

The solids content in the prepared animal effluent, cattle feedlots should be no more than 4%, pig farms - not Bo is 2%. They should not contain solid and long inclusions larger than 10 mm, while the application of sprinkling machines with hydraulic drive more than 2 mm [3].

When moving livestock watering runoff cattle feedlots on pig drains need to change the filter element.

As a result, reduced the scope and versatility of the diversion device.

The aim of the invention is to improve the reliability and quality of cleaning liquid such as animal waste complexes of cattle and pig farms from solid and fibrous structures.

This objective is achieved in that the intake device, comprising a housing with inlet and outlet ports mounted in the housing, a filter element provided with a diaphragm valve, a filter element made in the form of spring-loaded bell parts installed on the axis of square section having to commit on the end surfaces of the protrusions and depressions, and forming the filter channels, angled less than 90° to the axis of the filter, between which springs installed.

Comparative analysis with the prototype shows that the alleged diversion device complies with the criterion of "Novelty", as it has differences from the prototype.

1. Filter element issue is linen in the form of a bell parts.

2. Each part of the filter element made in the form of a bell.

3. In each compound the bell part of the filter element made poluchaly.

4. Bell form an integral part of end-to-end filter channels.

5. Filtering the channels formed by the bell component parts that are angled less than 90° to the axis of the filter.

6. The end surfaces of the tapered parts of the filter element is made grooves and ledges.

7. Between the bell component parts of the filter element springs installed.

8. On the axis of the square section of the filter element is installed spring.

9. The spring tension is set on the axis of the square section of the filter element, is regulated by the nut.

To prevent buildup of fibrous structures on the filter openings of the filter element is designed in the form of a bell parts. When operating the intake device of the fibrous structure are attracted by the flow of liquid to the filter element. When working is known intake device fibrous structure stick to the walls of the filter element.

When cleaning the holes or channels from the fibrous structures of the liquid flows from the filter element under a certain pressure.

The filter element intake device, the imp is United in the form of a bell parts, prevents the enveloping surface of the filter element of fibrous structures.

With the aim of creating a fluid flow along the filter element for cleaning of the filter channels of the diversion device is installed vertically with the aid of floats and is held in the middle layer of liquid, ready-to-use for irrigation, and an integral part of the filter element made in the form of a bell.

Due to the fact that the component parts of the filter element is made in the form of a bell, solids and fibrous structure during the cleaning of the filtering channels due to fluid flow is better washed off and fall to the bottom of the manure storage.

To fix and prevent arbitrary rotation around the axis of the filter element chime component parts mounted on the axis of the square section.

To filter the liquid in the bell composite parts made of filter channels located around the circumference.

When installing the bell parts with poluchaly the filter element in position are formed of filter channels, in which the liquid is cleared from the solids and fibrous structures.

During operation of the diversion device large solid impurities block the input of the filter channels, and the fibrous structure of nakaplu who are around the butt of the filter channels.

With the aim of creating a fluid flow moving along the longitudinal axis of the intake device, filtering the channels formed in the bell composite parts made at an angle less than 90° to the axis of the filter element.

Due to the fact that the filter channels are at an angle less than 90°, when cleaning of the filter element, the fluid coming from the pipeline when the pump stops) is fed under pressure into the filter element flows from the filter channel and moves along the filter element through the output orifice of the valve is displaced to a storage tank. That is, along the filter element is created by the liquid flow. Due to the fluid flow of the fibrous structure are removed from the filter channels and the filter element is displaced to a storage tank.

In the case of significant clogging of the filter, the pump is turned off and the liquid return flow enters from the suction pipe in the filter channels and clears them from solids and fibrous structures. Due to the fact that the composite parts are made in the form of a bell, which is made of filter channels at an angle less than 90° to the axis of the intake device, creates a fluid flow directed along the filter element. Due to the fluid flow of the fibrous structure detached from the ends of the filter channels and the bell with the stationary parts of the filter element.

For education filtration through channels and commit bell parts in position on the end surfaces of parts made grooves and protrusions. The protrusions some parts in the Assembly of the bell filter element is fixed in the grooves of the other components.

To form a filter channels and fixing bell parts on the axis of the filter element is installed spring. The spring tension adjust nut, which is wrapped on the axis of the filter element.

To change the size of the cross section of the filter channels between bell parts springs installed.

Spring placed around the circumference of the end surfaces of the bell component parts of the filter element.

In the case of significant clogging of the filter pump is switched off and the liquid return flow enters from the suction pipe in the filter channels and removes the impurities and fibrous structures. At this point in the cavity of the filter element, fluid pressure increases. By increasing the fluid pressure spring mounted on the axis of the filter element is compressed under the action of springs mounted between the bell components, the size of the cross section of the filter channels is increased. With increasing time the EPA section of the filter channels solids and fibrous structure, who stuck or clogged filter element, are fond of fluid flow and move through an outlet diaphragm valve from the intake device is displaced to a storage tank.

The signs of technical solutions proposed intake structures allow us to conclude about the technical solutions according to the criterion of "Significant differences".

Figure 1 shows the intake device, a longitudinal section (filter mode); figure 2 shows the intake device, a longitudinal section (cleaning mode filter channels).

The intake device includes a housing 1 with an inlet 2 and outlet 3 holes, which are respectively the inlet 4 and outlet 5 diaphragm valves, consisting of several sections. In the housing 1 is mounted a bell filter element made in the form of bell parts 6, 7, 8, 9, 10, 11 and 12. Bell integral part of 6, 7, 8, 9, 10, 11 and 12 mounted on the axle 13. The axle 13 has a square cross-section.

On the cylindrical part conical parts 6 and 7 7 and 8 8 and 9 9 and 10 10 and 11 11 and 12 made of half holes in the form of Polikanov at an angle α less than 90° to the axis 13, forming a filter channels 14.

Between bell parts 6, 7, 8, 9, 10, 11 and 12 the springs 15. The outer parts of the bell parts forming the filter channels 14, installed in the direction OS the ESD fluid stream.

Conical part 6, 7, 8, 9, 10, 11 and 12 forming the filter channels 14, mounted on the axle 13 having a square cross section, is compressed by a plate 16 having apertures 17 and plate 18, which compresses the spring 19. The tension of the spring 19 is regulated by the nut 20 through the washer 24.

To accurately capture the bell parts 6, 7, 8, 9, 10, 11 and 12, mounted on the axis 13, the grooves 21 and the protrusions 22.

The filter element consisting of a bell parts 6, 7, 8, 9, 10, 11 and 12 through the plate 16 bolts (bolts not shown) to the pipe 23.

The inlet valve 4 is hermetically fixed to the body 1 and the pipe 23.

The exhaust valve 5 is hermetically fixed to the housing 1.

The intake device is in filter mode (figure 1) and backwash (cleaning of the filter element) (figure 2).

The intake device is in filter mode as follows. Using floats intake device in an upright position held in the middle layers of manure storage, in which fluid is best prepared in structure to use for irrigation.

In filter mode, the liquid enters through the inlet valve 4 into the cavity formed by the housing 1 and the bell filter element, consisting of parts 6, 7, 8, 9, 10, 11 and 12. Further, the liquid passes through the filtering channels NR 14 in the inner part of the filter element, formed in the inner surface of the bell component parts and the axis 13 into the suction pipe 23. At this time, the exhaust valve 5 is closed, i.e. its free surface is pressed against the seat 24. Solids and fibrous structures being in fluid trapped at the entrance to filter the channels 14. Moreover, large solid impurities block the input of the filter channels 14, and the fibrous structure to accumulate on the walls of the filter channels 14 around their ends.

Filtering the channels 14, located at the inlet channel 4, purified from fibrous structures and solids the main stream of fluid moving from the inlet valve 4 in the cavity formed by the wall of the housing 1 and bell parts 6, 7, 8, 9, 10, 11 and 12 along the longitudinal axis of the filter element to the exhaust valve 5.

The intake device is in the mode of backwashing (cleaning of the filter element) (figure 2) as follows.

In the case of significant clogging of the filter element solid admixtures and fiber structures pump (not shown) is turned off and the liquid return flow enters from the suction pipe 23 in the filter channels 14 and removes the impurities. When the inlet valve 4 is closed and the outlet 5 opens. At this point in the inner cavity of the filter element is providing the fluid increases. In the result, the plate 18 is moved along the axis 13 and the spring 19 is compressed, and the bell integral part of 6, 7, 8, 9, 10, 11 and 12 are moved along the axis 13 under the action of springs 15. As a result, the size of the cross section of the filter channels 14 increases. By increasing the size of the cross section of the filter channels 14, the filter is cleaned from solids and fibrous structures in the channels 14.

Due to the fact that an integral part of 6, 7, 8, 9, 10, 11 and 12 is the bell, and the filter channels are at an angle less than 90°, solids and fibrous structure under the action of fluid flow directed along the filter element is moved to the exhaust valve 5, and then from the intake device is displaced to a storage tank.

When moving irrigation livestock wastewater complexes of bovine (cattle), in which the solids content should be no more than 4% and fibrous structures (inclusions) larger than 10 mm per irrigation sewage farms or in the application of sprinkling machines with hydraulic or electric drive, you must change the tension of the spring 19. The tension of the spring 19 is regulated by the nut 20.

The result changes the quality of cleaning of the filter channels 14 from solids and fibrous structures in fluids, prepared for irrigation.

The use of the proposed water intake device is provided in comparison with the known devices high quality self-cleaning filter element.

Due to the possibility of changing the size of the cross section of the filter channels, in the mode of backwashing (cleaning of the filter element) is a quality self-cleaning of the filter element from the solids and fibrous structures, and performance of component parts in the form of a bell prevents the build-up of fibrous structures on the filter element.

The use of the proposed water intake device provides increased scope for irrigation livestock effluents complexes of bovine cattle and pig farms in comparison with the known devices.

Using the proposed intake structures do not need to change the filter element when sprinkler irrigation machines with hydraulic or electric drive.

The intake device, comprising a housing with inlet and outlet ports mounted in the housing, a filter element provided with a diaphragm valve, characterized in that the filtering element is made in the form of a spring-loaded bell parts installed on the axis of square section having to commit on the end surfaces of the protrusions and depressions and forming the filter channels, angled less than 90° to the axis of the filter, between which the springs.
