Description

Technical Field

[0001] The utility model relates to the field of wastewater sedimentation tanks, in particular to a pollution cleaning device used in wastewater sedimentation tanks. Background Art

[0002] Cleaning wastewater sedimentation tanks is a crucial step in the sewage treatment process. Its purpose is to remove suspended solids, silt, and other particulate matter from the wastewater to improve water quality. Before cleaning begins, it is essential to ensure that the sedimentation tank is no longer receiving new sewage to prevent disruption to the cleaning process. The wastewater within the sedimentation tank must be drained to facilitate proper cleaning. Sludge and sediment are removed from the bottom of the sedimentation tank using a vacuum cleaner or manual cleaning. Long-standing sludge may require dissolution and cleaning using a high-pressure cleaning truck. Place the sewage treatment truck's suction pipe into the sludge, and use the truck's powerful suction to pump the sludge to a designated treatment location.

[0003] When using a sewage suction pipe for cleaning, due to the high viscosity and density of the deposited sludge, it is often necessary to use manual tools to shovel it. This process is not only labor-intensive but also inefficient. During operation, the sewage suction pipe needs to maintain an appropriate distance from the bottom of the sedimentation tank to ensure the sewage suction effect and prevent blockage. In actual operation, due to the complex shape of the bottom of the sedimentation tank and the uneven distribution of sludge, the position of the sewage suction pipe is difficult to support stably, and staff are usually required to manually support the sewage suction pipe for operation. This not only increases the labor intensity of the staff, but also easily leads to operational errors and affects the sewage cleaning effect. If the end of the sewage suction pipe is accidentally attached to the bottom wall of the sedimentation tank, the sewage suction pipe mouth will be blocked, and the sludge cannot be effectively sucked up, and the sewage suction pipe may even be damaged.

[0029] Reference Figures 1-4, a sewage cleaning device for a wastewater sedimentation tank, comprising: a sewage suction pipe 2, for transporting sludge in the wastewater sedimentation tank. As a key component of sludge transmission, the sewage suction pipe 2 can efficiently extract the deposited sludge at the bottom of the wastewater sedimentation tank and transport it to a subsequent treatment unit, effectively reducing the accumulation of sludge in the sedimentation tank, and maintaining the normal operation and efficient sedimentation effect of the sedimentation tank; a collecting mechanism 3, installed at one end of the sewage suction pipe 2, for collecting the deposited sludge in the wastewater sedimentation tank; the collecting mechanism 3 includes a collecting pipe 301 and a spiral conveying rod 304, one end of the sewage suction pipe 2 is connected to the collecting pipe 301, and the spiral conveying rod 304 is connected to the collecting pipe 301. In the collection pipe 301, which serves as a temporary storage container for sludge, the collection pipe 301 is tightly connected to the sewage suction pipe 2 to ensure the stability and continuity of the sludge during the transportation process and avoid sludge leakage or backflow. The spiral conveying rod 304 is used to lift the deposited sludge from the bottom of the sewage suction pipe 2 to the collection pipe 301. Through rotation, the spiral conveying rod 304 can easily lift the sludge deposited at the bottom of the sewage suction pipe 2 to the collection pipe 301, thereby improving the efficiency of sludge collection and reducing the need for manual cleaning; the support mechanism 4 is installed on the collection pipe 301 to provide support for the collection pipe 301 and the sewage suction pipe 2.

The handle 302 makes it easy for the operator to adjust the use position of the collecting pipe 301, thereby improving the convenience and flexibility of the work.

[0031] Reference Figure 3 The driving unit 5 is arranged on the collection pipe 301, and the driving unit 5 is connected to the spiral conveying rod 304 to provide rotational power for the spiral conveying rod 304; the driving unit 5 includes: an outer cover 501, which is installed on the collection pipe 301 to protect the internal power source 502 from the influence of the external environment, such as corrosion, pollution, etc., to ensure the stable operation of the power source 502; the power source 502 is installed in the outer cover 501, and the power source 502 of the power source 502 is connected to the spiral conveying rod 304 to provide rotational power for the spiral conveying rod 304. It is the core component of the efficient operation of the collection mechanism 3, which ensures the continuity and efficiency of the sludge collection process. The power source 502 adopts a servo motor and can also adopt a stepping motor.

[0032] Reference Figure 2 and Figure 4The support mechanism 4 includes: a support frame 401, which is installed on the collecting pipe 301; a number of support legs 402, which are installed on the support frame 401 and are used to provide support for the collecting pipe 301 to prevent the collecting pipe 301 from contacting the bottom of the wastewater sedimentation tank.

[0033] Reference Figure 1 , sewage suction machine 1, one end of the sewage suction pipe 2 is connected to the sewage suction machine 1, the sewage suction machine 1 is used to provide suction and pump sludge. As the power source 502 and control center of the entire sewage cleaning device, the sewage suction machine 1 extracts the sludge from the bottom of the sedimentation tank by providing strong suction and pumps it into the collection mechanism 3. Its efficient pumping capacity and stable suction output ensure the smooth progress of the sludge cleaning work, effectively reducing the difficulty and cost of manual cleaning. The operation of the sewage suction machine 1 also helps to reduce the accumulation of sludge in the sedimentation tank and maintain the sedimentation tank in good operating condition.

[0034] During use, the sewage cleaning device is moved to the side of the wastewater sedimentation tank, and it is ensured that all components are firmly connected, especially the connection between the sewage suction pipe 2 and the collection mechanism 3.

Under the suction of the sewage suction machine 1, the deposited sludge at the bottom of the wastewater sedimentation tank is sucked into the sewage suction pipe 2. The sludge moves with the air flow or water flow in the sewage suction pipe 2 until it reaches the collection pipe 301. The connected part enters the sludge in the collection pipe 301, and the power source 502 drives the spiral conveying rod 304 to rotate. Under the rotation of the spiral conveying rod 304, the sludge is gradually lifted from the bottom of the suction pipe 2 to the collection pipe 301. The continuous rotation of the spiral conveying rod 304 ensures the smooth lifting of the sludge and reduces the risk of sludge accumulation and blockage in the pipeline.

[0035] In summary, compared with the existing technology, it has the following beneficial effects:

[0036] By integrating the spiral conveying rod 304 in the collection mechanism 3, the deposited sludge can be automatically lifted from the bottom of the suction pipe 2 to the collection pipe 301 without the need for manual shoveling of the sludge, which significantly reduces labor intensity and improves the cleaning efficiency. The continuous rotation of the spiral conveying rod 304 ensures smooth transportation of the sludge and reduces the risk of sludge accumulation and blockage in the pipeline.

[0037] The support mechanism 4 can provide a stable support platform for the collection pipe 301 and the sewage suction pipe 2, ensuring that the sewage suction pipe 2 maintains an appropriate distance from the bottom of the sedimentation tank during operation, effectively preventing the sewage suction pipe 2 from being blocked and damaged due to direct contact with the bottom of the tank, and at the same time improving the accuracy and efficiency of sewage suction.

[0038] The flexibility of the support mechanism 4 allows the operator to easily adjust the angle and position of the collection pipe 301 according to the complex shape of the bottom of the sedimentation tank and the uneven distribution of sludge, ensuring that the suction pipe 2 is always aimed at the area where the sludge is most concentrated, further improving the cleaning effect.
