Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a flushing device for the inlet tank of a secondary sedimentation tank. Background Technology

[0002] Secondary sedimentation tank refers to a sedimentation tank after biological treatment, used to further separate activated sludge and water. Inlet tank refers to the water inlet part of secondary sedimentation tank. It is an important structural unit in the sewage treatment system. Its design, operation and maintenance directly affect the sedimentation effect and the quality of effluent.

[0003] In actual wastewater treatment processes, the original design was to allow water to enter the entire inlet channel evenly. However, during the treatment process, sludge easily accumulates in the inlet channel of the secondary sedimentation tank, which can clog the inlet holes and cause the water flow to decrease as it progresses, thus affecting the water intake of the secondary sedimentation tank. Utility Model Content

[0004] Based on the problems mentioned in the background technology above, this utility model provides a flushing device for the inlet tank of a secondary sedimentation tank, which is used to solve the problem that sludge is easily generated in the inlet tank of the secondary sedimentation tank during the sewage treatment process, which can easily block the inlet hole, resulting in the water flow becoming smaller and smaller as you go further, thus affecting the water intake of the secondary sedimentation tank.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A flushing device for the inlet tank of a secondary sedimentation tank, comprising:

[0007] A truss vehicle, which is movably mounted between guide rails at the top edges of the two walls of the inlet tank;

[0008] A water pumping component, which is mounted on a truss vehicle;

[0009] A silt flushing assembly, which is assembled under the truss vehicle via a suspension plate;

[0010] The silt flushing assembly includes a double-elbow pipe, which is suspended and assembled on a truss vehicle by a clamping plate. The middle part of the double-elbow pipe is connected to the outlet end of the pumping component through a connecting pipe. Both elbows of the double-elbow pipe have downward-facing bends, and multiple side spray holes are arrayed on the opposite peripheral walls of the two bends. A straight pipe is provided between the bottom ends of the two bends, and multiple bottom spray holes are arrayed at a 45° angle on the lower half of the front peripheral wall of the straight pipe. The nozzles of the two nearest bottom spray holes on the straight pipe face the bottom corner of the inlet tank.

[0011] Based on the above technical solution, the present invention has made the following improvements:

[0012] Furthermore, the truss vehicle includes two bases, and each base is rotatably equipped with a traveling wheel and two stabilizing wheels at its bottom. The traveling wheel is located between the two stabilizing wheels, and one end of the traveling wheel is connected to a servo drive shaft on the side wall of the base. A truss is provided between the two bases, and a support platform and a clamping plate are provided on the truss.

[0013] Furthermore, the water pumping component includes a water pump mounted on a support platform, the water pump being provided with an inlet pipe and an outlet pipe, one end of the inlet pipe being connected to an external suction pipe, and one end of the outlet pipe being provided with a water delivery pipe, one end of the water delivery pipe being connected to one end of a connecting pipe.

[0014] Furthermore, rollers are rotatably provided at both ends of the straight tube.

[0015] Furthermore, the top end of the bent pipe is located directly below the double-bend pipe, while the bottom end is located below the rear side of the double-bend pipe.

[0016] The beneficial effects of this utility model are:

[0017] 1. By using the combination of truss vehicle, water pumping unit and sludge flushing component, the water pumping unit pumps flushing water into the sludge flushing component. Then, the truss vehicle drives the water pumping unit and sludge flushing component to move at the top of the water inlet tank, causing the sludge flushing component to move and flush the tank wall and bottom.

[0018] 2. The nozzles of the two nearest bottom spray holes on the straight pipe face the bottom corner of the water inlet tank, so that the water sprayed from the bottom spray holes can wash away the silt at the bottom corner of the water inlet tank.

[0019] 3. The top of the bend is located directly below the double bend, and the bottom is located below and behind the double bend. This causes the bend to be distributed obliquely on the tank wall, so that the spray holes on the upper half of the bend wash the upper half of the tank wall before the spray holes on the lower half of the bend wash the lower half of the tank wall. This ensures that the flushing water sprayed from the spray holes on the lower half of the bend can finish washing the sewage traces flowing down the upper half of the tank wall, thus avoiding the presence of sewage traces on the lower half of the tank wall.

[0027] like Figures 1-4 As shown, a flushing device for the inlet tank of a secondary sedimentation tank includes:

[0028] The truss vehicle includes two bases 101, each with a rotatable traveling wheel 102 and two stabilizing wheels 103 rotatably mounted on its bottom. The traveling wheel 102 is located between the two stabilizing wheels 103, with one end of each traveling wheel 102 connected to a drive shaft of a servo motor 104 on the side wall of the base 101. The traveling wheel 102 and the two stabilizing wheels 103 are all located on guide rails at the top edge of the water inlet tank wall. When the servo motor 104 is activated to drive the traveling wheel 102 to rotate, it can move the base 101 on the guide rails. A truss 105 is provided between the two bases 101, with a support platform 106 and a clamping plate 107 on the truss 105. When the traveling wheel 102 rotates and moves the base 101 on the guide rails, it can move the truss 105 and the components on the truss 105 on the top of the water inlet tank.

[0029] The water pumping component is mounted on the truss vehicle. The water pumping component includes a water pump 201 mounted on the support platform 106. The water pump 201 is equipped with an inlet pipe 202 and an outlet pipe 203. One end of the inlet pipe 202 is connected to an external suction pipe. The inlet of the external suction pipe extends into the secondary sedimentation tank. One end of the outlet pipe 203 is equipped with a water delivery pipe 204.

[0030] The silt flushing assembly is suspended and assembled under the truss vehicle via a clamping plate 107. The silt flushing assembly includes a double-bend pipe 301, which is suspended and assembled on the truss vehicle via the clamping plate 107. The middle part of the double-bend pipe 301 is connected to one end of the water supply pipe 204 via a connecting pipe 302. Both bends of the double-bend pipe 301 are provided with downward-facing bends 303. Multiple side spray holes 304 are arrayed on the opposite peripheral walls of the two bends 303. Each side spray hole 304 can flush the wall of the water inlet tank.

[0031] A straight pipe 401 is installed between the bottom ends of the two bent pipes 303. Multiple bottom spray holes 402 are arranged in a 45° downward array on the lower half of the front peripheral wall of the straight pipe 401. Each bottom spray hole 402 can rinse the bottom of the water inlet tank. The bottom spray holes 402 are all located on the lower half of the front peripheral wall of the straight pipe 401 and are distributed at a 45° downward angle, which can promote the forward flow of the rinsing wastewater during the rinsing of the bottom of the water inlet tank. The nozzles of the two nearest bottom spray holes 402 on the straight pipe 401 are directed towards the bottom corner of the water inlet tank, so that the water sprayed from the bottom spray holes 402 can rinse the sludge at the bottom corner of the water inlet tank and prevent residue from remaining at the corner.

[0032] When the water pump 201 is started, water is drawn from the secondary sedimentation tank through the external suction pipe, allowing the water to enter the water pump 201. The water then flows through the outlet pipe 203, the water delivery pipe 204, and the connecting pipe 302 before entering the double elbow pipe 301. It then enters the two bend pipes 303. After the water enters the bend pipes 303, some of the water can be sprayed out from the side spray holes 304 to the tank wall, thereby rinsing the tank wall. The other part of the water enters the straight pipe 401 and is then sprayed out from the bottom spray holes 402 to rinse the bottom and corners of the tank. The straight pipe 401 is located behind the bend pipes 303, which allows the water sprayed from the bottom spray holes 402 of the straight pipe 401 to rinse the bottom and corners of the tank while also rinsing the wastewater flowing down the tank wall.

[0033] Furthermore, the top end of the bent pipe 303 is located directly below the double-bend pipe 301, while the bottom end is located below and behind the double-bend pipe 301. This causes the bent pipe 303 to be obliquely distributed on the tank wall, so that the spray holes 304 on each side of the upper half of the bent pipe 303 rinse the upper half of the tank wall before the spray holes 304 on each side of the lower half of the bent pipe 303 rinse the lower half of the tank wall. This allows the rinsing water sprayed from the spray holes 304 on each side of the lower half of the bent pipe 303 to rinse the lower half of the tank wall while simultaneously rinsing the wastewater traces flowing down the upper half of the tank wall. This prevents wastewater traces from remaining on the lower half of the tank wall, thereby improving the rinsing effect on the tank bottom and tank wall.

[0034] Both ends of the straight pipe 401 are equipped with rollers 403 that can rotate. The rollers 403 can move at the bottom of the tank and provide some support for the silt flushing components.

[0035] The present invention has been described in detail above. The specific embodiments are provided only to help understand the method and core idea of ​​the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
