The invention relates to wastewater treatment plants and can be used for containment and waste removal from wastewater in the first stage of their treatment.

A device for containment and extract the [1]

The disadvantage of this device is:

a) lack of parallel strips of the filter element along its length, which affects the quality of cleaning. Despite the long strips of the filter element they are along the entire length of nowhere is not fixed relative to each other. Structurally, this is impossible due to the location of the tines for a filter element having a through passage of the teeth of the tines in the openings of the filter element;

b) lack of a mechanism ensuring the penetration of the teeth of the tines in the openings of the filter element.

The aim of the invention is, firstly, improving the quality of treatment and, secondly, ensuring regulation of the relative position of the teeth of the tines and prozora filter element.

Stated first objective is achieved in that the device for containment and removal of debris from the wastewater containing a frame with a filter element, a cart with grabline wheel drive truck and the flushing mechanism, the trolley with grabline placed on the frame prior to the filtration element, and the length of the filter element and perpendicular to it, with an interval placed guides combs, grooves which are separated from each other in the Lena on sleeves, sitting on an axis, mounted on the trolley can move in the grooves of the truck, giving the different positions of the tines.

In Fig. 1 presents a General view of the device of Fig.2 is a view along arrow a of Fig.3, the flushing mechanism; Fig.4 element frame with the guide comb and a filter element of Fig.5 element mating tines and truck; Fig.6 view B in Fig.5.

Device for containment and removal of debris from the wastewater contains a frame 1, cart 2 actuator 3 and grabline 4. Frame 1 contains the filter element 5 in the form of parallel strips, which are fixed in grooves of the guide combs 6 installed at intervals along the length of the filter element 5. The grooves in the guide gribenko 6 are separated from each other by the amount of prozora filter element 5. On the frame 1 there are guides 7 to move the truck 2 (as when working stroke and at idle) and the tines 4 (working stroke) and the guides 8 to move the tines 4 at idle. The guides 7 are made in the form of a channel, within which is placed the rollers of the trolley 2 and with its outer surface contacting the rollers tines 4. On the frame 1 is pivotally mounted boxes 9 to the transfer roller tines 4 with the guide 7 in the direction the x end combined with the hinged ends of the check boxes 9, and the lower end is located above the lower end of the guide 7.

Truck 2 is a welded construction, which is attached grabline 4. Grabline 4 mounted on the bushings 10, sitting on the axis 11, is mounted on the carriage 2. Grabline 4 has the possibility of misalignment of the Prozorov filter element 5 by moving the axis 11 in the grooves truck with nuts 12 of the adjusting device consisting of a bushing 22 welded thereto by pins 23. Because the cleaning comb tines 4 is mounted on a fairly long longitudinal rods, and a set of the filter element is a strip with a thickness of about 5-8 mm, small enough padding on one side and loosening the other side of the nut 12, so that the teeth cleaning tines 4 coincided with the openings of the filter element.

Grabline 4 represents two longitudinal thrust, one end of which is fixed to the bushing 10, and the other is mounted a cleaning comb with teeth 13. Each rod is equipped with a roller 14. On the carriage 2 is provided by the lugs from a set of rubber plates (to hell. not specified) limiting the movement of the teeth of the tines and preventing their contact with the guide combs. Trolley 2 with grabline 4 rasmastuokiene on the frame 1 and is made in the form of two rods 16 with the plugs 17 and comb 18. To bring resetter 15 in motion in the upper part of the frame 1 in the guide 19 is installed thrust 20. Plugs 17 are connected with the rods 20 by means of cables 21.

The device operates as follows.

Trolley with 2 fixed to it grabline 4 by means of the actuator 3 from the original lower position moves upward stroke. This is the cleaning of the filter element 5. When exposed to truck 2 on pull 20 are moved in the guide rails 19 and operate the dumper 15 via cables 21, the fork 17 and rod 16. This comb 18 resets with the teeth of the comb 13 debris on the conveyor (not shown). Upon reaching the truck 2 upper position reset limit switch (to hell. not shown) and the carriage 2 starts to idle down.

When driving the truck up 2 the roller tines along the guides 7 are under the boxes 9 and when driving down the boxes 9, playing the role of a copier, translate them into the rails 8. When driving tines 4 down her comb is in the offside position prozora filter element 5. When reaching the roller tines 4 of the lower end of the guides 8 and they come off on the guide 7, the teeth cleaning comb 13 is fixed in the openings of the filter element 5. Next, the x trucks, giving the different positions of the rotor, which ensures the coincidence of the teeth of the latter with openings filtrage element.
