The device only cleans the reaction barrel, but does not clean the sediment in the sedimentation tank, resulting in excessive precipitation of dirt inside the sedimentation tank, thereby affecting the effect of the sedimentation tank in settling the dirt. Therefore, it is necessary to have the function of cleaning the dirt accumulated in the sedimentation tank. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1-Figure 6As shown, the utility model provides a technical solution: a high-efficiency phosphorus removal device for sewage treatment, comprising a support base 1, a sedimentation tank 2 for sedimentation after phosphorus removal from sewage is fixedly installed on the top of the support base 1, a stirring tank 3 for stirring phosphorus removal agent and sewage is fixedly installed on the top of the sedimentation tank 2 through an opened discharge channel, a stirring motor 301 is fixedly installed on the top of the stirring tank 3, a stirring paddle 302 extending to the inside of the stirring tank 3 is installed at the output end of the stirring motor 301 through an axis rod, a feeding port 303 is opened on one side of the top of the stirring tank 3, a partition 304 is fixedly installed on the bottom of the stirring tank 3, a feeding port is opened inside the partition 304, and a through groove is opened on one side of the inner wall of the feeding port, and the feeding port 303 is passed through the feeding port 303. Sewage is poured into the stirring tank 3. When the stirring tank 3 is filled with sewage, the operator delivers the prepared dephosphorization agent into the stirring tank 3 through the feed port 303. When the dephosphorization agent is delivered, the operator turns on the controller 7 to control the stirring motor 301 to be powered on. The powered stirring motor 301 drives the stirring paddle 302 to rotate and stir inside the stirring tank 3, stirring the sewage and the dephosphorization agent inside the stirring tank 3. The dephosphorization agent and sewage after stirring react chemically with the sewage through the chemical substances contained in the dephosphorization agent, thereby achieving the function of removing phosphorus contained in the sewage. A cleaning mechanism 5 for cleaning the sediment inside the sedimentation tank 2 is installed in a rotating manner inside the sedimentation tank 2. The cleaning mechanism 5 includes The driving motor 501 is fixedly mounted on the outer wall of the sedimentation tank 2 away from the discharge port 201 through a mounting plate. The output end of the driving motor 501 is fixedly mounted with a screw rod 502 extending into the interior of the sedimentation tank 2 through a shaft rod. The outer side of the screw rod 502 is threadedly sleeved with a push plate 503 through a threaded sleeve seat. A cleaning brush 504 for cleaning the inner wall of the sedimentation tank 2 is fixedly mounted on the outer side of the push plate 503. The operator turns on the controller 7 to control the driving motor 501 to be powered on. The powered driving motor 501 drives the screw rod 502 to rotate inside the sedimentation tank 2 through the shaft rod. The rotating screw rod 502 drives the push plate 503 to move parallel to the interior of the sedimentation tank 2 through the threaded sleeve seat. The parallel moving push plate 503 03 pushes the dirt settled at the bottom of the sedimentation tank 2 out through the discharge port 201, and at the same time drives the cleaning brush 504 to clean the inner wall of the sedimentation tank 2 through the parallel moving push plate 503, so that the cleaning brush 504 can clean the dirt attached to the inner wall of the sedimentation tank 2. A discharge port 201 is opened on one side of the sedimentation tank 2, and a sealing valve 6 is installed on the top of the sedimentation tank 2 away from the side of the stirring tank 3 through an axis. The operator manually opens the sealing valve 6 to facilitate the sealing valve 6 to detach from the inside of the discharge port 201, thereby opening the discharge channel, so that the sediment in the sedimentation tank 2 can be pushed out from the discharge port 201 through the push plate 503, so as to realize the cleaning of the sediment. The sealing valve 6 is an existing structure, so it is not described in detail.

[0024] As an implementation method in this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a blocking mechanism 4 is fixedly installed on the lower side of the mixing tank 3, and the blocking mechanism 4 includes an electric push rod 401. One end of the electric push rod 401 passes through the interior of the mixing tank 3 and extends to the through groove opened in the partition 304. A blocking plate 402 for blocking the discharge port opened in the partition 304 is fixedly installed on one end of the electric push rod 401. The operator turns on the controller 7 to control the electric push rod 401 to power on. The powered electric push rod 401 drives the blocking plate 402 to move parallel inside the partition 304. The parallel moving blocking plate 402 moves to the inside of the through groove, which is convenient for opening the discharge port of the partition 304, thereby facilitating the treated sewage to enter the sedimentation tank 2 for sedimentation.

[0025] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a controller 7 is fixedly installed on the outer wall of the sedimentation tank 2, and a control valve port 8 is fixedly installed on one side of the outer wall of the sedimentation tank 2 close to the discharge port 201. The controller 7 is electrically connected to the stirring tank 3, the electric push rod 401, the drive motor 501 and the control valve port 8 through a wire, so that the operator can control the device to power on and operate through the controller 7. The operator can open the water outlet by opening the controller 7 to control the control valve port 8, so as to release the water inside the sedimentation tank 2.

[0026] Working principle: Sewage is poured into the mixing tank 3 through the feed port 303. When the mixing tank 3 is filled with sewage, the operator delivers the prepared dephosphorization agent into the mixing tank 3 through the feed port 303. When the dephosphorization agent is delivered, the operator turns on the controller 7 to control the stirring motor 301 to be powered on. The powered stirring motor 301 drives the stirring paddle 302 to rotate and stir inside the mixing tank 3, stirring the sewage and dephosphorization agent inside the mixing tank 3. After stirring, the dephosphorization agent and sewage react chemically with the sewage through the chemical substances contained in the dephosphorization agent, thereby achieving the function of removing phosphorus contained in the sewage. When the sewage and the dephosphorization agent in the stirring tank 3 are stirred, and the operator turns on the controller 7 to control the electric push rod 401 to be powered on, the powered electric push rod 401 drives the blocking plate 402 to move parallel inside the partition 304, and the parallel moving blocking plate 402 moves to the inside of the through groove, which is convenient for opening the discharge port of the partition 304, so that the sewage after dephosphorization in the stirring tank 3 is transported to the inside of the sedimentation tank 2 through the discharge port and the discharge channel, so that the sedimentation tank 2 can precipitate the sewage after dephosphorization, and the dirt in the precipitated sewage accumulates at the bottom of the sedimentation tank 2, and the upper layer of the dirt is the water after dephosphorization that meets the discharge standard.

[0027] The operator opens the water outlet by opening the controller 7 to control the control valve port 8, so as to release the water inside the sedimentation tank 2. When the water inside the sedimentation tank 2 is released, the operator manually opens the sealing valve 6 to facilitate the sealing valve 6 to separate from the inside of the discharge port 201, thereby opening the discharge channel. At the same time, the operator turns on the controller 7 to control the drive motor 501 to power on. The powered-on drive motor 501 drives the screw rod 502 to rotate inside the sedimentation tank 2 through the shaft rod. The rotating screw rod 502 drives the push plate 503 to move parallel inside the sedimentation tank 2 through the wire sleeve seat. The parallel-moving push plate 503 pushes the dirt precipitated at the bottom of the sedimentation tank 2 out through the discharge port 201 that opens the discharge channel. At the same time, the parallel-moving push plate 503 drives the cleaning brush 504 to clean the inner wall of the sedimentation tank 2, so that the cleaning brush 504 can clean the dirt attached to the inner wall of the sedimentation tank 2.

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
