Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a sludge disposal device for a municipal sewage treatment plant that can be quickly cleaned. Background Art

[0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, and catering, and is also increasingly entering the daily lives of ordinary people. Sludge is the solid sediment produced after sewage treatment, which is highly polluting and cannot be directly discharged into nature. Therefore, sludge needs to be treated. Sludge treatment is a process of reducing the volume, stabilizing, and rendering harmless of sludge through concentration, conditioning, dewatering, stabilization, drying, or incineration. For modern sewage treatment plants, the treatment and disposal of sludge have become the most complex and costly part of the operation of the sewage treatment system. Before sludge treatment, it needs to be dewatered, and the existing equipment for dewatering sludge is relatively complex.

[0003] In the prior art, there is a sludge treatment device. After the sludge is introduced through a connecting cover, the rotating shaft and blades assist in crushing and dispersing some relatively large lumps of sludge in the sludge. The crushed sludge is then introduced into the inside of the extrusion chamber for extrusion and water removal, improving the efficiency of extrusion and water removal of the sludge.

[0004] However, when the above device is used, the sludge will block the filter holes on the filter plate, and the filter holes of the filter plate cannot be quickly cleaned. Disassembling and cleaning the filter plate is time-consuming and laborious. Summary of the Utility Model

[0005] Aiming at the above-mentioned defects or improvement requirements of the prior art, the purpose of the utility model is to provide a sludge disposal device for a municipal sewage treatment plant that can be quickly cleaned. Through the output of the output end of the second driving motor, the first limiting rod rotates. Since the filter plate is threadedly connected to the threaded end of the first limiting rod and the filter plate is restricted by two second limiting rods, the filter plate can move vertically close to the cleaning component, and the cleaning component can quickly dredge and clean the blocked filter holes on the filter plate.
