The invention relates to techniques for mechanical wastewater treatment and can be used in urban water supply and sewage farms and enterprises with self-contained sewage treatment.

Known devices of wastewater from waste containing carrier frame, the filter grille with vertical bars, drive, chain drive tines mounted on the chains, the mechanism for flushing waste (Moskvitin, A. C. Equipment water and sewage facilities, -M.: stroiizdat, 1979, page 80...81; EN 2144515 class. 02 F 3/10, E 02 In 5/08, 1999).

The disadvantages of the known devices are:

- possible deformation of the vertical rods of the lattice from the presence of fibrous and other small contaminants, such as wood chips, gravel, metal objects stuck in the holes tines after reset waste from the plane of the tines and intensive flow of waters;

- limited predislone space to capture grabline installed on the circuits of trash in front of the grating, which can lead to podporu wastewater.

A prototype of the proposed device adopted arc grid "rainbow" (Avenue of the joint stock company EKOMTEH, , Moskvin the tines, the reciprocating movement without breaking the teeth of the tines of the lattice, top cleaner, lower purifier located at the bottom of the grid.

The disadvantages of this device are:

- do not exclude the presence of fibrous impurities in the openings of the blades and the back of the grid after reset waste top cleaner with possible distortion of the rods when moving the tines down;

- flush waste from the plate tines on the edge of the plate;

the appearance of a vortex flow in front of the grate when moving the tines down with the dregs against the flow as flow rates, decrease the speed of water flow, which can lead under certain conditions, depending, for example, flow rate, density of dirt in front of the grate to the formation of a "jump" wastewater;

- the possibility of accumulation of trash directly on the surface of the bottom of the cleaner and samosogrevanie him from the reduction in the average speed of the lower jet stream before grabline at the bottom below the minimum, when waste precipitate and not carried away by the stream, and pressed to the bottom of the channel increased hydrostatic pressure due to the loss of the flow velocity and thus discarded by the reaction of the jet flow.

The invention relates to techniques for mechanical chestline, mounted on rollers for movement along the contour of the frame, the drive tines, the upper purifier waste, the cleaning mechanism plate, teeth and Prozorov tines, built-in cleaner.

The technical result consists in increasing the service life of the lattice, reducing backwater from expansion preresection and lattice space of wastewater from accumulation of waste.

The aim of the invention is to increase the service life of the lattice, reducing backwater sewage by expanding predislone space clean from trash.

The stated objective is achieved in that the device for the mechanical treatment of wastewater containing filter grille, base with installed grabline with the actuator and the top of the cleaner, a mechanism for cleaning the plate teeth and Prozorov tines after reset waste built into the top of the cleaner; the base is made in the form of left and right guide spatial frame of triangular outline; grabline made in the form of forks and mounted on rollers for movement along the contour of the frame; the filter grille is integrated into the frame; the drive tines made in the form of saryrn isdi in the form of a manifold with nozzles connected to a source of compressed air; the height of the triangular contour of the frame is chosen equal flow of water for 1 s at the minimum allowable average flow velocity in front of the grating and the width of the plate tines is equal to half the height of the triangular contour of the frame, on the surface of the plate has holes with a diameter equal to 6-8 mm

In Fig.1 shows a device for wastewater treatment; Fig.2 - the same, left side view, and Fig.3 - section a-a in Fig.2; Fig.4-manifold for compressed air; Fig.5 is an enlarged image D in Fig.1 - rink tines moves on the vertical part of the contour of the inclined, Fig.4 - manifold for compressed air.

The device contains a filter grille 1; grabline made in the form of forks and mounted on rollers 3; the drive tines 4, made in the form of lever mechanism; top cleaner 5 with a built-in mechanism 6 for cleaning plates, teeth and Prozorov tines, made in the form of a header with nozzles; guide spatial frame 7 triangular contour with mobile strip 8 on the axis 9 to provide continuous movement of the tines. Between the upper end of the filtration grid and the top of the cleaner 5 is placed flat panel display 1 is to supply the give full control ability to supply compressed air to the manifold. For regulating the pressure provides a pressure regulator (not shown).

The cleaning device is installed in the inclined channel and may be provided with a pivot bearing 14 and rotated, if necessary, repair or inspection using the lifting means.

The device operates as follows.

Include the actuator 4, grabline 2 is moved in a closed triangular contour of the frame 7 and captures waste in predislone space, and then trash, hold the filter grating 1, and transports them on a flat screen 10 to the upper purifier 5, with rink 3 tines affects the bar 8, which is rotated on an axis 9, allowing the roller to move in an inclined portion of the path, and strap under their own weight occupies the former position. Top cleaner sends garbage chute in the container or conveyor ( not shown); at this point, the Cam 12 during the rotation of drive shaft 11 acts on the switch 13 associated with the dispenser (not shown), and compressed air is supplied to the reservoir and through the nozzle acts on the plate, the teeth and the holes tines. After the disappearance of the Cam 12 and a switch 13, the compressed air is stopped.CLASS="ptx2">
