Because the upper end surface of the baffle plate 92 is arranged in an inclined shape, the baffle plate has a good guiding effect, and the mounting frame 71 is pushed forcefully at the moment, so that the mounting frame 71 pushes the baffle plate 92 to drive the locking plate 91 to slide downwards along the locking groove 17.
Until the mounting frame 71 moves between the two baffle plates 92, the locking plate 91 drives the baffle plates 92 to slide upwards along the locking grooves 17 under the action of the elastic force of the spring 93. When the upper end surface of the locking plate 91 abuts against the lower end surface of the mounting frame 71 and the two baffle plates 92 jointly clamp the side wall of the mounting frame 71, the positions of the mounting frame 71 and the filter screen 72 are quickly limited. Then the cover plate 2 is closed and the above operation is repeated to realize the sludge cleaning capability below the mounting grooves 15 on both sides.
Referring to fig. 2 and 3, the upper end surfaces of the two mounting grooves 15 are each inclined, and the upper end surfaces of the two mounting grooves 15 close to each other are lower than the upper end surfaces far away from each other.
The mud scraping plate 6 comprises a hard plate body 61, a rubber scraping plate 62 is fixedly connected below the plate body 61, and side wings 63 which can be abutted against the bottom wall of the tank body 1 are arranged on two sides of the bottom end of the scraping plate 62. A plurality of drainage holes 19 are formed through the plate body 61, and the scraper 6 is abutted against the ends of the two mounting grooves 15 through the scraper 62 in the moving process.
Because the up end of mounting groove 15 all is the slope form setting, when the sedimentation tank during operation, the sedimentary silt of sewage prevents the silt deposit at the up end of mounting groove 15 along the sedimentation tank bottom of the 15 up end landing of mounting groove to make things convenient for the later stage to the unified processing of silt.
Compared with the hard scraper 62, the scraper 62 made of rubber can be better attached to the bottom wall of the tank body 1 and the inner side wall of the tank body 1. Because the resistance that receives water in the scraper blade 62 motion process for scraper blade 62 drives flank 63 and produces slight bending, and at this moment, the lateral wall of flank 63 can support tight cell body 1 diapire, makes scraper blade 62 and cell body 1 diapire laminate more, thereby further improves and strikes off the effect.
The plurality of water discharge holes 19 can effectively reduce the resistance of the plate body 61 in water, so that the plate body 61 can move more stably in water, and the energy consumption of the motor 4 is reduced. The mud scraping plate 6 is in the removal in-process, and the terminal surface conflict of scraper blade 62 and mounting groove 15 forms sealed silt processing space with cell body 1 diapire and three side inner walls, and wash port 19 all is located the top in silt processing space this moment, can not influence the sealed degree in silt processing space to improve the job stabilization nature of sedimentation tank.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
