Description

Technical Field

[0001] This utility model relates to the technical field of kitchen wastewater treatment equipment, specifically a pneumatic sludge lifter. Background Technology

[0002] In the process of treating kitchen wastewater, there are multiple sedimentation tanks, namely primary sedimentation tank, secondary sedimentation tank, intermediate sedimentation tank and inclined tube sedimentation tank. Their function is to separate mud and water. In actual use, the mud and water separation effect is obvious.

[0003] For the disposal of sludge deposited in sedimentation tanks, the sludge can be discharged by opening a pipe at the bottom. This method is simple and does not consume additional energy. Alternatively, a water pump can be used to extract and discharge the sludge from the sedimentation tank. However, the high concentration of sludge can easily lead to difficulties in pumping, causing the water pump to overload, run dry, and be damaged. To solve this problem, a pneumatic sludge lift can be used for sludge discharge.

[0004] However, in common pneumatic sludge lifters, the air outlet is located inside the sludge extraction pipe. After extraction, the sludge inside the pipe easily adheres to the surface of the air pipe, clogging the air outlet and affecting the next use. Therefore, a pneumatic sludge lifter is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pneumatic sludge lifter, which has the advantages of flushing and unblocking the air holes after sludge extraction to prevent clogging, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pneumatic sludge lifting device includes a sedimentation tank, an internal sludge suction pipe, a connecting air pipe fixedly installed on one side of the sludge suction pipe, an air outlet pipe fixedly installed at one end of the connecting air pipe extending into the interior of the sludge suction pipe, air holes opened on the surface of the air outlet pipe, a cleaning connector fixedly installed on one side of the air outlet pipe, a cleaning valve fixedly installed on the surface of the cleaning connector, and an anti-clogging component provided on one side of the sedimentation tank.

[0008] The anti-clogging component includes a water tank fixedly installed on one side of the sedimentation tank, an installation base plate fixedly installed on one side of the water tank, a water pump fixedly installed on the top of the installation base plate, an output pipe fixedly installed at the output end of the water pump, a connector fixedly installed at one end of the output pipe, a pumping pipe fixedly installed at the input end of the water pump, and one end of the pumping pipe connected to the water tank.

[0009] Furthermore, an air inlet pipe is fixedly installed at the top end of the connecting air pipe, an air inlet valve is fixedly installed on the surface of the air inlet pipe, and a sludge outlet flange is fixedly installed at the top end of the sludge suction pipe.

[0010] Furthermore, square tubes are fixedly installed on both sides of the sedimentation tank that are far apart from each other. A longitudinal sliding block is slidably installed on the inner side wall of the square tube, and a longitudinal base plate is fixedly installed on the top of the longitudinal sliding block.

[0011] Furthermore, a mounting plate is fixedly installed on the top of the longitudinal sliding base plate, and a transverse guide rod is fixedly installed between the two mounting plates.

[0012] Furthermore, a mounting plate is fixedly installed on the surface of the mud suction pipe, and two transverse connecting plates are fixedly installed on the top of the mounting plate, one of which is slidably installed on the surface of the transverse guide rod.

[0013] Furthermore, a transverse sliding screw is rotatably mounted between the two mounting plates, and the transverse sliding screw is threadedly connected to one of the transverse sliding connecting plates.

[0014] Furthermore, a transverse motor is fixedly installed on one side of the mounting plate, and the output end of the transverse motor is fixedly connected to one end of the transverse screw.

[0015] Furthermore, a longitudinal sliding screw is rotatably mounted on the inner wall of one of the mounting square tubes, and the longitudinal sliding screw is threadedly connected to the longitudinal sliding slider. A longitudinal sliding motor is fixedly mounted on one end of one of the mounting square tubes, and the output shaft of the longitudinal sliding motor is fixedly connected to one end of the longitudinal sliding screw. A water supply pipe is fixedly mounted on one side of the water tank.

[0016] Compared with the prior art, this utility model provides a pneumatic sludge lifting device, which has the following beneficial effects:

[0017] 1. This pneumatic sludge lifter uses a water tank installed on one side of the sedimentation tank. A water pump draws water from the tank. After the sludge is removed, the connector is connected to the cleaning connector, and clean water is introduced into the air pipe. The clean water enters the air outlet pipe, opening the air hole and preventing blockage. This solves the problem of common pneumatic sludge lifters where the air outlet is located inside the sludge extraction pipe. After extraction, sludge inside the pipe easily adheres to the surface of the air pipe, blocking the air outlet and affecting the next use.

[0018] 2. This pneumatic sludge lifting device, by fixing the sludge suction pipe to the mounting plate, uses a horizontal and vertical motor to drive the sludge suction pipe to move, thereby extracting all the sludge from the sedimentation tank. This eliminates the need for manual movement of the sludge suction pipe during sludge extraction, reducing workload. Attached Figure Description
