The fixed cover is equipped with two reels 155 on the pivot 152, and it has second stay cord 156 all to wind on two reels 155, and two second stay cords 156 are the same in the direction of winding on corresponding reel 155, and an end plate 44 corresponds a second stay cord 156 and bonds with it.
Referring to fig. 1, 2 and 5, after enough sundries are accumulated on the bottom plate 43, a worker firstly rotates the rotating disc 153 manually, the rotating disc 153 drives the reels 155 to rotate through the rotating shaft 152, the two reels 155 simultaneously wind the corresponding second pull ropes 156, and the two second pull ropes 156 are matched to lift the whole filter assembly out of the filter tank 1.
The rotary plate 153 is slidably provided with a plug pin 154, the bracket 151 is provided with a plug hole (not shown) for inserting the plug pin 154, and when the filter assembly is lifted to a sufficient height, a worker inserts the plug pin 154 into the plug hole, so that the filter assembly is kept in a suspended state.
Through the arrangement of the filtering assemblies, sundries in the filtering tank 1 are all located on the bottom plate 43, and under the action of the lifting assemblies, the filtering assemblies can completely bring the sundries out of the filtering tank 1, so that the completeness of cleaning the sundries in the filtering tank 1 is improved.
Referring to fig. 2 and 3, the worker then takes the hooks 9 off the corresponding hanging rings 10, and then manually rotates the end plate 44, the end plate 44 drives the corresponding main plate 5 and the corresponding auxiliary plate 6 to rotate, and when the two floating plates are staggered, the deformation force of the compressed spring 7 pushes the auxiliary plate 6 to extend out of the telescopic cavity 51.
Until the auxiliary plate 6 is abutted against the bottom plate 43 and the worker continues to rotate the end plate 44, the auxiliary plate 6 is gradually retracted into the telescopic cavity 51 under the action of the relative interference of the bottom plate 43, and the auxiliary plate 6 can scrape sundries from the bottom plate 43, so that the worker can conveniently remove the sundries on the bottom plate 43.
Referring to fig. 3, next, the worker hangs the hooks 9 on the corresponding hanging rings 10, and rotates the end plate 44 in the reverse direction to be vertical, and the main plate 5 and the sub-plate 6 are rotated to be horizontal. In the same operation manner as described above, the other end plate 44, the other main plate 5, and the other sub plate 6 can scrape off all the remaining foreign materials on the bottom plate 43.
Referring to fig. 1 and 2, as the worker removes the sundries on the bottom plate 43, a portion of the sewage may be carried out of the filtering tank 1 by the sundries. Therefore, the outer side walls of the two opposite end plates 44 of the filter tank 1 are respectively integrally formed with the return tank 11 with an open top, and a plurality of return pipes are communicated between the bottom wall of the return tank 11 and the filter tank 1.
When sundries are cleaned from the bottom plate 43 to the return tank 11, sewage is brought into the return tank 11 and flows back to the filter tank 1 through the return pipe, and workers clean the sundries in the return tank 11 after the sundries are sufficiently dried.
Referring to fig. 1, 5 and 6, in order to prevent the unfiltered sewage from being discharged from the water outlet pipe in the process of removing the impurities in the filter assembly by workers, a plugging slot 101 is vertically arranged at the position of the side wall of the filter tank 1, which is opposite to the position communicated with the water inlet pipe 2, and a plugging inserting plate 16 is inserted and matched in the plugging slot 101.
Referring to fig. 1, 5 and 6, the plugging insertion plate 16 is provided with a through hole 161 for communicating the water inlet pipe 2 with the filtering tank 1, the top of the plugging insertion plate 16 is connected with an elastic pulling rope 18, and the elastic pulling rope 18 is wound on the rotating shaft 152.
When a worker lifts the filter assembly through the lifting assembly, the rotating shaft 152 winds the elastic pull rope 18, and the plugging insertion plate 16 can be driven to move upwards. The plugging insert plate 16 has completely plugged the inlet conduit 2 before the bottom plate 43 has moved higher than the inlet conduit 2.
Referring to fig. 1, 5 and 6, the filter tank 1 is bolted with a limit barrier 17 at a position opposite to the top of the plugging slot 101, and the limit barrier 17 limits the plugging insertion plate 16, thereby reducing the possibility that the plugging insertion plate 16 is completely pulled out of the plugging slot 101.
The embodiment of the application provides a municipal domestic sewage environmental protection processing system's implementation principle does:
the sewage enters the filtering assembly through the first filtering holes 410 through the water inlet pipe 2, and the impurities can only be accumulated on the bottom plate 43 because the aperture of the impurities is larger than that of the second filtering holes 420.
The worker rotates the turntable 153, the turntable 153 drives the two reels 155 to rotate in the same direction through the rotating shaft 152, and the two second pull ropes 156 cooperate to lift the whole filter assembly out of the filter tank 1. The worker inserts the insertion pin 154 into the corresponding insertion hole to lock the turntable 153, and the filter assembly is suspended.
Meanwhile, the rotating shaft 152 rolls the elastic pull rope 18, the elastic pull rope 18 pulls the plugging insertion plate 16 to move upwards, the through hole 161 and the water inlet pipe 2 are staggered, and the plugging insertion plate 16 plugs the water inlet pipe 2.
The worker takes the hook 9 off the suspension loop 10, pulls the locking pin 14 out of the locking slot, and then rotates an end plate 44, and the end plate 44 drives the main plate 5 and the auxiliary plate 6 to rotate. After staggering two subplates 6, the subplate 6 stretches out the telescopic cavity 51 and butts against the bottom plate 43 under the action of the deformation force corresponding to the pressure spring 7, the worker continues to rotate the end plate 44, the subplate 6 gradually retracts into the telescopic cavity 51, and meanwhile, sundries are scraped from the bottom plate 43 to the back of the backflow tank 11. Then, the worker re-attaches the hook 9 to the corresponding loop 10, rotates the end plate 44, and inserts the locking pin 14 into the corresponding locking insertion hole. The above operation is repeated, and the impurities left on the bottom plate 43 are scraped to another return tank 11 through another end plate 44.
Thereafter, the worker pulls out the plug pin 154, reversely rotates the rotary plate 153, unwinds the second draw cord 156 by the reel 155, and the filter assembly descends back into the filter tank 1. The rotating shaft 152 also unreels the elastic pull rope 18, the plugging inserting plate 16 moves downwards, and the through hole 161 is communicated with the water inlet pipe 2 again.
