DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-3The utility model provides a technical solution: a rapid cleaning device for a sewage treatment plant grid, comprising a frame 11, wherein a plurality of parallel grid bars 12 are arranged in the frame 11, a top plate 13 is fixed on the top of the grid bars 12, and lifting plates 17 are correspondingly provided on both sides of the grid bars 12, and a cleaning brush 19 that contacts the side surfaces of the grid bars 12 is provided in the arc-shaped groove 18 on the inner side of the lifting plate 17, a connecting block 21 is provided at the end of the lifting plate 17, and the bottom of the connecting block 21 is connected to the cylinder 24 through a lifting rod 23, a water distribution pipe 25 is provided on the outer side of the lifting plate 17, one end of the water distribution pipe 25 is connected to a water pump 26, one end of the water pump 26 is connected to a water inlet pipe 27, and a plurality of nozzles 28 are provided on the other side of the water distribution pipe 25.

[0018] In the above solution, a base 1 is provided at the bottom of the frame 11 .

[0019] In the above solution, the top plate 13 is snapped into the slot 14 at the top of the frame 11. Limit blocks 15 are provided on both sides of the top plate 13, and a pull rod 16 is provided at the top of the top plate 13. Specifically, the design of the pull rod 16 makes it easy to pull the top plate 13 and the grille bars 12 upward as a whole, thereby facilitating the disassembly and cleaning of the grille equipment.

[0020] In the above solution, an elastic scraper 2 is provided on the inner side of the cleaning brush 19. The surface of the elastic scraper 2 is roughened to enhance its resistance to dirt, and under its action, it can clean hard-to-remove dirt. By providing a lifting plate 17 on the outer side of the grille bar 12, the grille bar 12 is correspondingly clamped in the arc-shaped groove 18 of the lifting plate 17, so that the cleaning brush 19 contacts the outer surface of the grille bar 12. In addition, a connecting block 21, bolts 22, lifting rods 23 and cylinders 24 are provided for use in conjunction with each other, which can quickly drive the lifting plate 17 up and down to scrape off the attachments on the surface of the grille bar 12, thereby achieving a rapid cleaning effect on the grille bar 12. In addition, the two sets of lifting plates 17 are connected in a convenient disassembly method, which can facilitate the disassembly and maintenance of the equipment, reducing the cost of use.

[0021] In the above solution, adjacent connecting blocks 21 are connected by bolts 22. Furthermore, the connecting blocks 21 are connected to the top ends of the lifting rods 23 in a detachable manner.

[0022] In the above embodiment, the end of the water inlet pipe 27 is connected to the water supply mechanism. Furthermore, by providing the water distribution pipe 25, water pump 26, water inlet pipe 27, and nozzle 28, as the lifting plate 17 moves up and down, the water pump 26 can cause air to be ejected at high speed through the nozzle 28. This powerful water flow then cleans debris from the surface of the grille bars 12, effectively achieving efficient cleaning of the grille structure.

[0023] In the above embodiment, the opening of the nozzle 28 is located in the upper area of the arc-shaped groove 18. Under the action of the water pump 26, water is introduced from the water inlet pipe 27 into the water distribution pipe 25, and then pressurized and sprayed out through the nozzle 28. The water flow impacts the surface dirt of the grille bars 12 from the side, separating the dirt from the grille bars 12 and achieving a cleaning effect.

[0024] Working principle:

[0025] When this type of sewage treatment plant screen rapid cleaning device is used, the screen mechanism is set in the frame 11 to form a blocking effect, and two sets of lifting plates 17 are correspondingly set on both sides of the screen bars 12, and the connecting block 21 is connected by bolts 22. When the surface of the screen bar 12 is dirty and adhered after long-term use, the cylinder 24 is started, and the cylinder 24 drives the connecting block 21 and the lifting plate 17 to move up and down through the lifting rod 23. In this process, the cleaning brush 19 and the elastic scraper 2 inside the arc groove 18 are used to scrape off the dirt attached to the surface of the screen bar 12. At the same time, under the action of the water pump 26, water is introduced from the water inlet pipe 27 into the water distribution pipe 25 and then pressurized and sprayed out through the nozzle 28, so that the water flow impacts the surface dirt of the screen bar 12 from the side, so that the dirt is separated from the screen bar 12 to achieve a cleaning effect. When the screen mechanism needs to be disassembled and maintained as a whole, the top plate 13 can be driven upward by the pull rod 16 to achieve disassembly and maintenance of the screen mechanism.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
