The invention relates to the technology of mechanization of loading and unloading of railway transport, in particular to methods of hydraulic cleaning of railway wagons from stuck or frozen remnants of previously shipped bulk materials.

Known methods of hydraulic cleaning gondolas continuous water jets using pumps on the inside and outside of the gondola, this washed away the remnants of the cargo in the form of slurry (slurry) is coming into the sump. The clarified water from the tank is discharged into the pond, where secondary is spotted cargo./ Ed. D. C. Plyukhina. M. Transport, 1989, S. 216-219).

The disadvantages of these methods should include the inefficiency of the process of separating the granular material from the pulp and the impossibility of its secondary use in the national economy.

Closest to the invention, the technical solution adopted as the closest analogue is the setting of the Chelyabinsk plant "Vtorchermet" with a giant portal, pumping stations, water tanks and two sumps. Cleaning is performed by the water jets from giant performing oscillatory motion in the vertical plane (Loading and unloading of bulk cargoes. / Ed. by D. C. Plyukhina. M. Transport, 1989, S. 216).

The disadvantages of the method include the inefficiency of the process of separating the solid and liquid phases of the slurry and the impossibility of this separation process to re-use the allocated bulk materials, because they are in the mix (coal, gravel, sand, crushed stone and other) and made with high humidity, which is unacceptable in the condition of utilization in the winter.

The technical result consists in increasing the efficiency of the cleaning process gondolas, separating the pulp into its components, woskie ensuring environmental cleanliness of the process.

It is achieved by the fact that before the beginning of the process of hydraulic cleaning produce the sort of gondola cars by type of residue, and in the technological chain of the item based on two identical drying chains, are separately treated with a slurry of coal and inert residues with subsequent recycling. After precast sump slurry is separated into a stationary sieve the pulp with a particle size of more than 2 mm and less than 2 mm, the pulp containing particles larger than 2 mm are referred to Bagher-sump, from which Bagher-the Elevator is divided into particles larger than 2 mm and overflowing with content of particles less than 2 mm, which together with the pulp, is divided into a stationary sieve with particle sizes less than 2 mm, is directed to a clarifier-sludge, where they perform the concentration of particles less than 2 mm and then sent for belt vacuum filter, which emit a particle size of from 0.05 to 2 mm, combine them with particles larger than 2 mm and shipped to the consumer, and draining the water lamella clarifier-sludge and filtrate vacuum filter serves in the technical water tank and then pump to the nozzles jetting. Process water with particles razmara is the Nuits two cards covered lagoons for sludge from the sedimentation of particles with size less than 0.05 mm, and from the second card to the indoor sump pumps pump clarified earlier technical water in the system and remaining in this map sediment mud pumps serves to drain the sump, which combined with the slurry containing particles of size from 0.05-2 mm, dehydrate it in clarifier-sludge and belt vacuum filter and sent to the consumer.

Sort of gondolas on quality criteria residues (coal and inert) allows separate treatment, which leads to the formation of the pulp or only with coal residues, or only with inert residues. In the technological chain of the paragraph there are two identical drying chains, which are separately processed pulp with coal and inert (And) residues, which are separately fed to the warehouse and can be re-used for its intended purpose. In the case of mixing (coal and inert residues) cannot be used again, and it is necessary to allocate landfills where they are buried.

Technological scheme of cleaning gondolas and food processing washdown shown in the drawing.

The method includes collecting spillage when opening hatches, washing the floor the lid on the fixed slit sieve, dewatering and classification of the oversize of the dewatering Elevator, transportation dehydrated product to the warehouse, collecting undersize product in the sump and feed it into thin clarifier-sludge, thickening of undersize product in thin clarifier-sludge, sludge dewatering lamella clarifier-sludge on the belt vacuum filter, transportation dehydrated product to the warehouse together with dehydrated product of the Elevator, collecting clarified water with a thin layer of the illuminator and the filtrate and feeding them into the tanks, industrial water supply industrial water pumps at the giant.

Upon reaching the concentration of solids in the circulating water 40 kg/m3produced water treatment. This includes indoor tanks with two cards, one of which water is discharged from the system solution. Settled the clarified water from the second card is pumped into the system, and the residue from this map served in the drain sump, from which it enters the clarifier-sludge and belt vacuum filter, where dewatered sludge is sent to the conveyor and then to the warehouse.

Thus, the technological scheme of PR material (coal, inert granular materials).

For cleaning gondolas use monitor installation. The giant hung over passing underneath the gondola. Barrel vibrations jetting is carried out in a vertical plane transversely of the movement of the gondola. When testing single-jetting was observed that the velocity fluctuations giant 1 wave 2 with speed gondola more than 2 km/h appear "dead" (untreated) areas.

To avoid this, the proposed method uses the triple giant, whose trunks are located at a distance of 0.5 m from each other and the axis location of the shafts coincides with the axis of the railroad tracks. The giant has a device that allows for control of frequency and amplitude.

The motion of the gondola more than 5 km/h and the oscillation frequency of giant 1 wave 2 with the "dead" untreated zones are not formed.

Due to the fact that technological scheme for cleaning gondolas and frozen remnants of previously transported cargo are solid thick jets with water pressure before the nozzle jetting up to 3 MPa, was calculated loads on the surface is>The=1,456 kg/cm2that is 2.5 times less than the requirements in the transportation of goods (Technical conditions of loading and securing cargo. M. Transport, 1990), the components of PCP= 3,68 kg/cm2. Given the non-stationary mode of exposure jetting jet on the surface of the car, you can ensure safe cleaning without mechanical damage, etc.

The slurry formed in the process of cleaning gondola jets and feed into the overall flow of spillage of scraper conveyors, gravity fed from the sump to the receiving device on the tray on the stationary sieve preliminary dehydration with crack size is 2 mm, where the separation of the material. Particles smaller than 2 mm go into the drain sump, and particles > 2 mm in Bagher-sump dewatering Elevator. Overflow from Bagher-sump flows into the drain sump. When transporting the Elevator is the dehydration of the material to a moisture content of 15-18% and its supply to the conveyor belt and then to the warehouse.

From the drain sump underflow stationary sieve and overflow Bagher-sump serves on the thickening in the lamella clarifier-sludge, which produces thickening hard to concentrat swagat dehydration product particle size less than 2 mm and sent to the conveyor belt and then to the warehouse.

Drain the clarified water clarifier-sludge and filtrate belt vacuum filter is served in the technical water tank and then pump to the nozzles jetting. The cycle is closed.

The drawing is a flow diagram of a circuit apparatus for hydraulic cleaning gondolas from stuck and frozen remnants of previously shipped bulk materials.

The gondolas with the remnants of previously transported bulk material are formed on the sorting devices in structures with homogeneous cargo of two types - coal and inert residues. Then the composition remains homogeneous delivered to the receiving device at a speed of about 1 km/h

The receiving device is divided into 4 blocks. In the first unit of length equal to the 2 gondolas (30 m), to produce the opening side hatches open wagons. For quality cleaning (100% ) gondola from stuck or frozen remnants of previously shipped loose materials in the residue is not more than 3 enough opening two extreme hatches with one of the longitudinal sides of the gondola. All spillage gets to drag conveyors, located on both sides of the gondola, and moves in a sump receiver.

In the third block length of 15 m is blowing gondola targeted pressure jet of air to remove free water from the surface of the gondola. In intertrack spaces of the third block paved grooves with a slope toward the sump to drain water from the gondola in the sump receiver.

In the fourth block length of 30 m is the mechanical closing hatches gondola and quality treatment of industrial TV.

Cleaning gondola is jetting setup 1, the collection of slurry in sump receiving device 2, preliminary dehydration and separation of the pulp on a fixed sieve 3. Depending on what remains of the received composition in the receiving device (coal (U) or inert (And), using, for example, the gate 4 is directed to the slurry with particles larger than 2 mm in Bagher-sump 5 coal (U) or inert (And) remains.

Dehydration cont the R 7 and further to the warehouse 8.

The slurry with a particle size of less than 2 mm) is fed into the drain sump 9 coal (U) or inert (And) remains.

Overflow from Bagher-sump 5 and underflow stationary sieve 3 flows into the overflow sump 9, divided by the qualitative composition of the corps, 4. Next, the slurry overflow from the sump 9 enters the clarifier-sludge collector 10, respectively, in coal (Y) or inactive (I), where the thickened to a density of 600 kg/m3comes on belt vacuum filter 11, which is the dehydration of the firm and its supply to the conveyor 7 and next to the warehouse.

Drain clarifier-sludge (clarified water with solid density 1 kg/m3) and the filtrate belt vacuum filter is served in the technical water tank 12 and the high-pressure pump 13 to the nozzles jetting.

As the use of technical water in circulation it accumulates particle size less than 0.05 mm and at a concentration of 40 kg/m3and starts more intensive wear (especially large impact wear is exposed to high-pressure pumps). Therefore, for industrial water purification from accumulated sediment with particle size less than 0.05 mm, i.e. when reaching a concentration of 40 kg/m33pump 17 serves to drain the sump 9 for further separation of solid and liquid in the clarifiers-sludge ponds 10 and belt vacuum filter 11.

Thus, the proposed technology hydraulic cleaning of railway wagons continuous jets of water from stuck or frozen remnants of previously shipped loose materials differs from the prototype more effective methods of cleaning gondolas and new means for dewatering of solids and clarification of process water, allowing you to fully utilize washed cars remains of bulk materials with ensuring environmental cleanliness processes while ensuring high throughput receptor (approximately 1500-2000 gondola cars per day) item hydraulic cleaning of railway wagons.
