Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for cleaning scum from the surface of a water tank. Background Technology

[0002] Secondary sedimentation tanks, also known as sludge settling tanks, are used in wastewater treatment to separate sludge from water. They clarify the biologically treated liquor and concentrate the sludge in the liquor. The secondary sedimentation tank is also the final stage of biological wastewater treatment, playing a crucial role in ensuring that the suspended solids content of the effluent meets standards.

[0003] Currently, the scum generated in the secondary sedimentation tanks of wastewater treatment plants mainly comes from the scum produced by the biological treatment system and the scum that floats to the surface after nitrification of sludge in the secondary sedimentation tank. This is a frequent occurrence in wastewater treatment operations. If not cleaned in a timely manner, it not only affects the appearance of the secondary sedimentation tank, but excessive scum can also produce toxins that affect the quality of the discharged water. Although existing secondary sedimentation tank equipment is designed with devices such as scum baffles and baffles to intercept scum for easier cleaning, these interception methods cannot completely remove the scum, especially leaving a significant amount of scum residue at the edges of the secondary sedimentation tank, resulting in poor scum removal efficiency.

[0004] Therefore, there is an urgent need for a device to clean scum from the surface of a water tank, with the assistance of a scum-blocking plate, to further clean the scum and improve the scum removal effect of wastewater. Summary of the Invention

[0049] The working principle of this utility model is as follows: During the manufacturing of this water tank surface scum cleaning device, care is taken to control the weight of the device and the height of the inlet 13, ensuring that when the device is placed in the water tank, the lower edge of the inlet 13 is slightly below the water surface. In use, the device is placed in the water tank, and under the buoyancy of the water, it floats, with the lower edge of the inlet 13 slightly below the water surface. If the lower edge of the inlet 13 is higher than the water surface, external force can be applied to press down the device, causing a certain amount of water to enter the tank 11, increasing the device's weight and causing it to sink, thus making the lower edge of the inlet 13 slightly below the water surface. At this time, water mixed with scum enters through the inlet 13, and the scum remains on the cleaning filter 22, while the water enters the tank 11 through the cleaning filter 22. Simultaneously, the suction force of the submersible pump 31 drains the water in the tank 11 into the water tank through the drain outlet 33. During the drainage process, the reaction force of the drainage can be used as the driving force for the device to move on the water surface, or the movement of the device can be controlled by external force. Furthermore, to ensure a continuous flow of water and scum into the tank 11, the inlet 13 of the device needs to be slightly below the water surface. Therefore, a connecting pipe 6 is used to connect the device to the water in the pool, and a float level switch 5 is installed inside the connecting pipe 6. Utilizing the principle of communicating vessels, the water level in the connecting pipe 6 is kept level with the water level in the pool. When the float 54 falls down the float rod 51 to the lower stop, it indicates that the entire device is relatively light, the lower edge of the inlet 13 is close to the water surface in the pool, and there is little water in the tank 11. At this time, the relay coil is de-energized, controlling the submersible pump 31 to de-energize, and water and scum continue to enter the tank 11 through the inlet 13. When the float rises up the float rod 51 to the upper stop, it indicates that the device has sunk, the lower edge of the inlet 13 is submerged deep in the pool, and there is too much water in the tank 11. To prevent the device from sinking further, the relay coil is energized, controlling the submersible pump 31 to energize, and the filtered water in the tank 11 is continuously discharged through the drain outlet 33. This structure ensures that the height of the tank 11 remains within a certain range, guaranteeing a continuous inflow of water and scum, while preventing the device from sinking. When a significant amount of scum accumulates, the device is powered off, and workers use other tools to move it to the edge of the pool. The filter mechanism 2 is then removed and replaced with a new one, or the filter screen 22 is cleaned and reused.
