Embodiment two:
referring to fig. 2, the difference between the present embodiment and the first embodiment is that a buffer mechanism 4 is disposed between the water inlet pipe 2 and the bottom of the cylinder 1, the buffer mechanism 4 includes a water receiving bucket 41 and a diversion component 42, the top of the water receiving bucket 41 has an opening, the water receiving bucket 41 is made of stainless steel, the water receiving bucket 41 is welded on the side wall of the cylinder 1 far from the water inlet pipe 2, and the water receiving bucket 41 is located between the water inlet pipe 2 and the submersible pump. Be fixed with honeycomb duct 43 between inlet tube 2 and the water receiving bucket 41, the one end welding of honeycomb duct 43 is in the intercommunication department of inlet tube 2 and barrel 1, the other end welding of honeycomb duct 43 is on the lateral wall of water receiving bucket 41 orientation inlet tube 2, between inlet tube 2 and the honeycomb duct 43, between honeycomb duct 43 and the water receiving bucket 41, honeycomb duct 43 slope sets up, honeycomb duct 43 and the intercommunication department of inlet tube 2 are higher than honeycomb duct 43 and water receiving bucket 41's intercommunication department 3~5cm, and be provided with a plurality of buffering floater 411 in the water receiving bucket 41, all the adhesion has spacing rope 412 on the buffering floater 411, spacing rope 412 keeps away from the one end adhesion of buffering floater 411 on the inner wall of water receiving bucket 41. This structure makes sewage flow into the water receiving hopper 41 along the flow guide pipe 43 after flowing out of the water inlet pipe 2, and the flow velocity of sewage is reduced after flowing through the flow guide pipe 43, and when the flow velocity of sewage is large, the buffer floating ball 411 forms buffer for sewage.
Referring to fig. 2, the sewage in the water receiving bucket 41 is guided to the bottom of the cylinder 1 along the sidewall of the cylinder 1 by the diversion component 42, specifically, the diversion component 42 includes a drainage tube 421, the drainage tube 421 is a circular stainless steel tube, the drainage tube 421 is welded on the inner wall of the cylinder 1 in a surrounding manner, the drainage tube 421 is fixed with a diversion disc 422, the diversion disc 422 is made of stainless steel and the cross section of the diversion disc 422 is in a 'C' -shape, the inner annular wall of the diversion disc 422 is welded on the inner annular wall of the drainage tube 421, the outer ring of the diversion disc 422 extends to the inner wall of the cylinder 1, and the outer ring of the diversion disc 422 and the inner wall of the cylinder 1 have a 3-4 cm distance. The inner annular wall of the flow guiding disc 422 is provided with a plurality of flow dividing ports 4211, the flow dividing ports 4211 are round and uniformly distributed on the inner annular wall of the drainage tube 421 at a part lower than the connection part of the drainage tube 421 and the flow guiding disc 422, and the flow dividing ports 4211 are communicated with the inner space of the drainage tube 421 and the cylinder body 1.
Referring to fig. 2, in order to reduce the situation that the sewage overflows the water receiving bucket 41 to drop into the bottom of the cylinder 1 with greater potential energy when the sewage in the high water period is more, the water receiving bucket 41 may be further communicated with the overflow pipe 5. One end of the overflow pipe 5 is welded on the side wall of the water receiving bucket 41 facing the water inlet pipe 2, the other end of the overflow pipe 5 extends downwards to the bottom of the barrel 1 along the vertical direction, one end of the overflow pipe 5 away from the water receiving bucket 41 is connected with a shower nozzle 51 in a threaded manner, the communicating position of the overflow pipe 5 and the water receiving bucket 41 is located at the upper part of the water receiving bucket 41, and a 1m distance is reserved between the shower nozzle 51 and the bottom of the barrel 1. After the water level reaches the diversion port 4211, the sewage flows out from the diversion port 4211 and falls on the diversion disk 422 under the action of gravity, flows along the diversion disk 422, and flows down along the inner wall of the cylinder 1 after passing through the gap between the diversion disk 422 and the inner wall of the cylinder 1. During the water-filling period, the speed of sewage entering the water receiving hopper 41 exceeds the speed of sewage flowing out of the water receiving hopper 41, the sewage has a tendency to overflow the water receiving hopper 41, the redundant sewage can flow into the overflow pipe 5, and then the sewage is shunted through the shower nozzle 51 and flows into the accumulated water at the bottom of the cylinder body 1. The structure can lead the potential energy of sewage to be smaller when the sewage flows into the cylinder body 1, thereby leading the flow velocity of accumulated water in the cylinder body 1 to be smaller and being beneficial to the dirt to be deposited to the bottom of the cylinder body 1.
Various dirt is suspended in the sewage entering the cylinder 1, and the dirt is difficult to precipitate when the sewage flow rate is high. The sewage is guided to the buffer mechanism 4 through the guide pipe 43, the buffer mechanism 4 forms buffer to reduce potential energy carried by the sewage, so that the sewage can flow into the bottom of the cylinder 1 more stably, after the sewage forms accumulated water, the accumulated water forms layering, dirt which is easy to gather and form solid sediment gradually settles to the lower part of the accumulated water because of the calm water body, and the upper part of the accumulated water is sewage with less dirt. The submersible pump in the barrel 1 is arranged between the bottom wall of the barrel 1 and the buffer mechanism 4, the submersible pump is closed when the water level in the barrel 1 in the dead water period is low, the submersible pump is started when the water level in the barrel 1 in the high water period is high, and the submersible pump pumps out the sewage with cleaner accumulated water upper layer, so that the service life of the prefabricated pump station is prolonged.
Referring to fig. 2, after the dirt is deposited on the bottom of the cylinder 1, the rotating motor 31 drives the main plate 321 to rotate, and because the rotating motor 31 adopts a slow motor, the probability of generating a water flow with a faster flow rate when the main plate 321 rotates in the accumulated water is smaller, and when the main plate 321 rotates, the dirt moves towards the inner wall direction of the cylinder 1 under the action of centrifugal force when the main plate 321 sweeps, and falls into the dirt collecting tank 11 under the action of gravity. The auxiliary plate 322, which is rotated by the rotation motor 31, then pushes the dirt to move in the dirt collection tank 11. Dirt falls into the drain 111 under the force of gravity as it moves through the drain 111.
The implementation principle of the self-cleaning pretreatment prefabricated pump station provided by the embodiment of the application is as follows: the sewage with a faster flow rate flows into the cylinder body 1 from the water inlet pipe 2, flows into the water receiving hopper 41 along the flow guide pipe 43, the flow rate of the sewage is slowed down after flowing into the water receiving hopper 41, flows into the drainage pipe 421 under the action of gravity and flows out from the flow dividing port 4211, the sewage is divided into a plurality of water flows by the flow dividing port 4211 and then falls on the flow guide disc 422, then the sewage flows along the flow guide disc 422, flows down along the inner wall of the cylinder body 1 and flows into the accumulated water at the bottom of the cylinder body 1, the water flow in the accumulated water is gentle, and dirt can be settled to the bottom of the cylinder body 1 and gathered by the dirt collecting mechanism 3 and swept into the sewage discharging port 111.
