[0016] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] When the present utility model is specifically implemented, in combination with Figures 1 to 2 A shell sealing structure of a sewage filter, including a filter body 1, a fixed sleeve 2 is firmly fixed on the upper part of the filter body 1, providing necessary support and stability. A lifting sleeve 3 is arranged outside the fixed sleeve 2. Connection structures 4 and a fixing structure 7 are respectively arranged on both sides of the upper part of the lifting sleeve 3. The upper end of the connection structure 4 is fixedly connected to a sealing cover 5. A cavity is provided at the lower part of the sealing cover 5. A sealing ring 6 is fixed inside the sealing cover 5 to prevent liquid leakage;

[0018] During the implementation of the present utility model, a thread is arranged outside the fixed sleeve 2, a thread is arranged inside the lifting sleeve 3, and the fixed sleeve 2 is threadedly connected to the lifting sleeve 3. By rotating the lifting sleeve 3, the sealing cover 5 is driven to lift and lower, so that the sealing ring 6 seals the upper part of the filter body 1.
