Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a high-efficiency and environmentally friendly sedimentation tank. Background Technology

[0002] Sedimentation tanks are key structures used in water treatment, wastewater treatment, or industrial processes to separate suspended solids through gravity settling. Their core principle is to utilize gravity to allow suspended particles with a density greater than water (such as silt, organic matter, and chemical precipitates) to naturally settle to the bottom, thereby achieving solid-liquid separation.

[0003] Submersible sludge pumps are typically installed in sedimentation tanks to discharge settled sludge. For example, a sludge discharge device for a sedimentation tank in wastewater treatment, as proposed in utility model patent application number CN202022354566.8, includes a submersible sludge pump, a water distribution network, and a sludge discharge pipe. The outlet of the water distribution network is connected to the inlet of the submersible sludge pump, and the sludge outlet of the submersible sludge pump is connected to the sludge discharge pipe. The shape of the water distribution network is adapted to the bottom of the sedimentation tank, and the branches of the water distribution network are evenly distributed along the bottom of the sedimentation tank. Each branch of the water distribution network is evenly provided with multiple water inlets.

[0004] However, for sludge with high viscosity, oil or fibrous materials, the sludge is prone to sticking to the pipe wall, causing blockage of the sewage pipe. Utility Model Content

[0005] In view of this, it is necessary to provide a high-efficiency and environmentally friendly sedimentation tank to solve the problem of sludge with high viscosity, oil or fibrous materials, which easily sticks to the pipe wall and causes blockage of sewage pipes.

[0006] This utility model provides a high-efficiency and environmentally friendly sedimentation tank, including a sedimentation tank body, a sewage pump, a sewage pipe, and a suction assembly; the bottom of the sedimentation tank body has a sludge discharge port; one end of the sewage pipe is connected to the sludge discharge port of the sedimentation tank body, and the other end is connected to the feed end of the sewage pump; the suction assembly includes a suction tube, a piston, and a driving component; the suction tube is connected to the sewage pipe, the piston is slidably and sealed inside the suction tube, the driving component is fixedly connected to the suction tube, and the output end of the driving component is connected to the piston to drive the piston to slide so that the sludge flows between the sewage pipe and the suction tube.

[0007] Furthermore, there are multiple abdominal suction components, which extend along the length of the drain pipe.

[0008] Furthermore, the abdominal suction tube and the sewage pipe are arranged perpendicular to each other.

[0009] Furthermore, the abdominal suction tube is inclined toward the sewage pipe, and the end of the abdominal suction tube away from the sewage pipe is positioned away from the sewage pump relative to the end of the abdominal suction tube that is closer to the sewage pipe.

[0010] Furthermore, the piston includes a plug body, a sealing ring, and a rod body. The sealing ring is fitted onto the outer wall of the plug body, and the outer wall of the sealing ring slides against the inner wall of the suction tube. The side of the plug body away from the drain pipe is connected to the output end of the drive unit via the rod body.

[0011] Furthermore, the driving component is a hydraulic cylinder.

[0012] Furthermore, it also includes a flushing assembly, the flushing end of which passes through the piston and is connected to the interior of the abdominal suction tube or the interior of the drain tube.

[0013] Furthermore, the flushing assembly includes a flushing pipe and a connecting pipe. A water inlet channel is provided on the piston. The flushing pipe is fixedly disposed on the side of the piston near the drain pipe.

[0015] Furthermore, it also includes two guide wheels and two torsion springs. The two guide wheels are rotatably connected to the abdominal suction tube via the two torsion springs, and the connecting tube is disposed through the gap between the two guide wheels.

[0016] Compared with existing technologies, when the sewage pipe is blocked, the drive unit can be activated to drive the piston to slide back and forth in the suction tube, so that the sludge flows back and forth in the suction tube and the sewage pipe, avoiding sludge caking and effectively breaking up the sludge, so that the sewage pump can extract the sludge from the sewage pipe.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0021] like Figure 1-2 As shown, this utility model provides a high-efficiency and environmentally friendly sedimentation tank, including a sedimentation tank body 100, a sewage pump 200, a sewage pipe 300, and a suction assembly 400. A sludge discharge port is formed at the bottom of the sedimentation tank body 100. One end of the sewage pipe 300 is connected to the sludge discharge port of the sedimentation tank body 100, and the other end is connected to the feed end of the sewage pump 200. The suction assembly 400 includes a suction pipe 410, a piston 420, and a drive component 430. The suction pipe 410 is connected to the sewage pipe 300. The piston 420 is slidably and sealed within the suction pipe 410. The drive component 430 is fixedly connected to the suction pipe 410, and its output end is connected to the piston 420 to drive the piston 420 to slide so that sludge flows between the sewage pipe 300 and the suction pipe 410.

[0022] During implementation, when the sewage pipe 300 is blocked, the drive component 430 can be activated to drive the piston 420 to slide back and forth in the suction pipe 410, thereby causing the sludge to flow back and forth in the suction pipe 410 and the sewage pipe 300, preventing the sludge from caking and effectively breaking up the sludge so that the sewage pump 200 can extract the sludge from the sewage pipe 300.

[0023] In this embodiment, the sedimentation tank body 100, the sewage pump 200, and the sewage pipe 300 are the core components of the entire sewage sedimentation treatment system. Impurities in the sewage in the sedimentation tank body 100 accumulate at the sludge discharge port under natural sedimentation, and flow along the sewage pipe 300 under the suction generated by the sewage pump 200, and are finally discharged to the designated location.

[0024] However, for sludge with high viscosity, oil or fibrous materials, the sludge is prone to caking, which can clog the drain pipe 300. Therefore, this embodiment of the utility model solves the above problem by setting up a suction component 400.

[0025] The suction assembly 400 in this embodiment includes a suction tube 410, a piston 420, and a drive component 430. The suction tube 410 is connected to the sewage pipe 300. The piston 420 is slidably and sealed inside the suction tube 410. The drive component 430 is fixedly connected to the suction tube 410. The output end of the drive component 430 is connected to the piston 420 to drive the piston 420 to slide so that the sludge can flow between the sewage pipe 300 and the suction tube 410, effectively breaking up the sludge and preventing sludge caking.

[0026] In this embodiment, there are multiple abdominal suction components 400, which extend along the length of the drain pipe 300. It is understood that the number of abdominal suction components 400 should be determined according to the length of the drain pipe 300.

[0027] In one embodiment, the abdominal suction tube 410 and the sewage pipe 300 are arranged perpendicular to each other.

[0028] like Figure 3 As shown, in another embodiment, the suction tube 410 is angled toward the drain pipe 300, with the end of the suction tube 410 away from the drain pipe 300 positioned away from the drain pump 200 relative to the end closer to the drain pipe 300. This configuration allows the piston 420 to push the sludge within the drain pipe 300 toward the drain pump 200.

[0029] In this embodiment, the piston 420 includes a plug body, a sealing ring 421, and a rod body. The outer wall of the plug body is fitted with the sealing ring 421, and the outer wall of the sealing ring 421 slides against the inner wall of the abdominal suction tube 410. The side of the plug body away from the drain pipe 300 is connected to the output end of the drive member 430 via the rod body.

[0030] In one embodiment, the drive component 430 is a hydraulic cylinder. Of course, it can also be implemented using electric actuators, linear motors, or other structures; there is no limitation on this.

[0031] This embodiment also includes a flushing assembly 500, the flushing end of which passes through a piston and is connected to the interior of the suction tube 410 or the drain pipe 300. If the sludge in the drain pipe 300 is too compacted and has poor fluidity, high-pressure water can be introduced through the flushing assembly 500 to break up the compacted sludge and lubricate the sludge flow.

[0032] In one embodiment, the flushing assembly 500 includes a flushing pipe 510 and a connecting pipe 520. A water inlet channel 422 is provided on the piston 420. The flushing pipe 510 is fixedly disposed on the side of the piston 420 near the drain pipe 300. One end of the flushing pipe 510 is connected to one end of the water inlet channel 422, and the other end of the flushing pipe 510 is closed. A plurality of round holes are provided on the outer wall of the flushing pipe 510. The connecting pipe 520 is fixedly disposed on the side of the piston 420 away from the drain pipe 300. One end of the sealing ring 421 is connected to the other end of the water inlet channel 422, and the other end of the sealing ring 421 is connected to a water source.

[0033] The flushing assembly 500 also includes a water pump and a water tank, and the sealing ring 421 is connected to the water tank via the water pump.

[0034] This embodiment also includes two guide wheels and two torsion springs. The two guide wheels are rotatably connected to the suction tube 410 via the two torsion springs, and the connecting tube 520 is disposed through the gap between the two guide wheels. With the above arrangement, interference between the connecting tube 520 and the output end of the drive member 430 is avoided during the movement of the connecting tube 520 with the piston 420.

[0035] Compared with the existing technology: When the sewage pipe 300 is blocked, the drive component 430 can be opened to drive the piston 420 to slide back and forth in the suction pipe 410, so that the sludge flows back and forth in the suction pipe 410 and the sewage pipe 300, avoiding sludge caking and effectively breaking up the sludge, so that the sewage pump 200 can draw out the sludge in the sewage pipe 300.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
