Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment sedimentation tank. Background Technique

[0002] A sedimentation tank is a structure that uses sedimentation to remove impurities and suspended solids in water, and is a device for purifying water quality. The main principle is to utilize the natural sedimentation or coagulation sedimentation of water to remove solid impurities such as suspended solids and sediment in water, as well as some suspended substances and particulate matters, so as to reduce the turbidity of sewage and further improve water quality.

[0003] In practical applications, we found that although the current sedimentation tank can coagulate and sediment most of the impurities in water during use, due to differences in treatment processes and different impurity properties, there are often a small amount of fine floating substances that are difficult to be flocculated and settled after the sewage is coagulated and sedimented, floating on the water surface of the sedimentation tank, which brings inconvenience to the cleaning work and is also not conducive to the subsequent treatment and utilization of water.

[0023] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0024] Figures 1-4 Shown is a schematic diagram of the entire structure of a sewage treatment sedimentation tank of the present utility model. Please refer to Figures 1-4 A sewage treatment sedimentation tank of this embodiment includes a tank body housing 100. One end of the tank body housing 100 has a discharge port 110. A U-shaped discharge trough 200 spanning across the inner side of the tank body housing 100 is rotatably installed at the inner lower edge of the discharge port 110. The U-shaped discharge trough 200 is composed of a trough lower edge 2001 below the liquid level and a trough upper edge 2002 above the liquid level. The U-shaped discharge trough 200 is driven by a driving device to rotate the upper end of the trough upper edge 2002, and the side of the U-shaped discharge trough 200 at the trough upper edge 2002 is close to the inner side of the discharge port 110. A water pushing plate 300 which is hollow inside is horizontally arranged across the upper end inside the tank body housing 100, and the bottom of the water pushing plate 300 is higher than the liquid level. A plurality of air spray holes 310 are arranged on the side of the water pushing plate 300 facing the discharge port 110. The water pushing plate 300 is driven by a driving mechanism to reciprocate along the direction of the discharge port 110.

[0025] Both ends of the U-shaped discharge trough 200 have rotating shafts 210 respectively fixed to the ends of the trough upper edge 2002, and the rotating shafts 210 are rotatably installed on the tank body housing 100. A rotating motor 200 with an output end connected to at least one rotating shaft 210 is further arranged outside the tank body housing 100. When the water pushing plate 300 pushes the floating objects on the water surface into the U-shaped discharge trough 200, the rotating motor 200 can drive the U-shaped discharge trough 200 to rotate rapidly through the rotating shafts 210, so that the trough lower edge 2001 immediately swings towards the discharge port 110, and the water and floating objects in the trough are poured out from the discharge port 110.

[0026] A support beam 120 is fixed at the top of the pool shell 100 and near the discharge port 110, a fixing nut 410 is arranged in the center of the upper end of the water pushing plate 300, a threaded screw 400 is threadedly connected to the inner side of the fixing nut 410, and one end of the threaded screw 400 is rotatably mounted on the support beam 120 and the other end is rotatably mounted on the end of the pool shell 100, and a servo motor 420 whose output end is connected to the threaded screw 400 is also arranged at one end of the outer side of the pool shell 100; linear sliding assemblies 500 are also arranged at both ends of the top of the water pushing plate 300; the linear sliding assembly 500 includes a sleeve 510 fixed to the upper part of the water pushing plate 300, and a guide rod 520 slidably arranged on the inner side of the sleeve 510; wherein, one end of the guide rod 520 is fixed to the support beam 120 and the other end is fixed to the inner side of the pool shell 100. In this embodiment, when it is necessary to clean the floating objects on the liquid surface of the pool body, the servo motor 420 drives the threaded screw 400 to rotate, and with the cooperation of the fixed nut 410 and the linear sliding assembly 500, the water pusher plate 300 is pulled to move from one end of the pool body toward the discharge port 110. During this process, the water pusher plate 300 can blow and push the floating objects on the liquid surface of the pool body across through the several jet holes 310 on its lower inclined surface under the injection of high-pressure air source, so that the floating objects gradually accumulate and drift into the U-shaped discharge trough 200, thereby achieving the purpose of automatically sweeping away garbage. The operation is simple, which brings convenience to the cleaning work and is also beneficial to the subsequent treatment and utilization of water.

[0027] The water pusher plate 300 has a chamber 320 connected to the jet hole 310 inside, and a connecting nozzle 330 connected to the chamber 320 is also provided at one end of the outer side of the water pusher plate 300, and the connecting nozzle 330 is connected to the high-pressure air source through an external pipe; wherein, the water pusher plate 300 is arranged in an inclined state, and the side at an acute angle to the liquid surface faces the direction of the discharge port 110. It can be understood that the inclined water pusher plate 300 can maximize the coverage area of ​​the blown air flow, and under the action of high wind pressure, the floating objects on the liquid surface can be fully covered and blown forward.

[0028] Furthermore, the upper end of the water pusher plate 300 also has a mounting seat 600 for fixing the fixing nut 410 and the sliding sleeve 510. The fixing nut 410 and the sliding sleeve 510 can be conveniently positioned and installed by the provided mounting seat 600.

[0029] In summary, for a sewage treatment sedimentation tank according to this embodiment, when it is necessary to clean the floating objects on the liquid surface of the tank body, the servo motor 420 drives the threaded lead screw 400 to rotate, and under the cooperation of the fixed nut 410, the linear sliding assembly 500, etc., the water pushing plate 300 is thus pulled to move from one end of the tank body towards the discharge port 110. During this process, under the injection of high-pressure air source, the water pushing plate 300 can blow and push the floating objects on the liquid surface of the tank body in a crosswise manner through a plurality of air injection holes 310 on its lower inclined surface, so that the floating objects gradually accumulate and drift into the U-shaped discharge trough 200. Subsequently, the rotating motor 200 can drive the U-shaped discharge trough 200 to rotate rapidly through the rotating shaft 210, so that the lower edge opening 2001 of the trough body immediately swings towards the discharge port 110, so that the water and floating objects in the trough body are poured out from the discharge port 110, thereby achieving the purpose of automatically sweeping the garbage. The operation is simple and brings convenience to the cleaning work.
