[0022] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. In addition to liquids, the discharged sewage also contains a large amount of solid waste. The sewage treatment of sewage treatment plants can only treat sewage but not these wastes;
[0023] The existing methods of collecting garbage from sewage are mostly done manually, and in the case of a small number of devices, the removal of garbage also requires manual assistance, which generally requires a certain amount of manpower and is not labor-saving enough;
[0024] Sewage is discharged into the pretreatment device 1 and flows down along the filter net bag 3, wherein the garbage contained therein is left by the filter net bag 3, and all that remains in the pretreatment device 1 is liquid. Then, when there is too much garbage remaining in the filter net bag 3 and it needs to be cleaned, the first motor 17 is turned on, and the first motor 17 drives the active bevel gear 16 to rotate, thereby allowing the driven bevel gear 15 to rotate accordingly, so that the screw 14 can rotate in the movable groove 13. In this case, the threaded sleeve 24 is lifted and lowered along the limiting slide groove 12, thereby lifting and lowering the combination of the inner interlayer cylinder 2 and the filter net bag 3 together, so that the filter net bag 3 is exposed;
[0025] The filter net bag 3 is used to automatically filter the garbage contained in the sewage. When the garbage accumulates to a certain level, the filter net bag 3 can be pushed out of the pretreatment equipment 1 without human assistance, which makes it easier for the staff to clean up the garbage and debris, thereby improving the convenience of sewage pretreatment.
[0026] In other embodiments, the present embodiment discloses, please Figure 3 As shown, a positioning rod 25 is provided on the top end face of the threaded sleeve 24, a positioning slot 22 is provided on the inner side of the connecting groove 21, and the positioning rod 25 is movably inserted into the inner side of the positioning slot 22; through this design, when the threaded sleeve 24 enters the connecting groove 21, the positioning rod 25 also enters the positioning slot 22, thereby strengthening the connection.
[0027] In other embodiments, the present embodiment discloses, please Figure 3 As shown, a limiting groove is provided on the outer side of the threaded sleeve 24, and a limiting convex strip is provided on the inner side of the connecting groove 21, and the limiting convex strip is slidably connected to the inner side of the limiting groove; through this design, the tightness of the connection between the threaded sleeve 24 and the inner interlayer tube 2 can be further strengthened without increasing the complexity of the operation.
[0028] Embodiment 2:

An empty slot 10 is opened on the inner side of the pretreatment device 1, and a second motor 34 is provided on the inner side of the empty slot 10. The output end of the second motor 34 is transmission-connected to the connecting rod 33, and a bearing is provided at the connection between the connecting rod 33 and the empty slot 10. A positioning slider 31 is provided on the outer side of the filter net bag 3, and a positioning slide groove 23 is opened on the inner side of the inner interlayer cylinder 2. The positioning slider 31 is slidably connected to the inner side of the positioning slide groove 23;
[0030] The second motor 34 is turned on and drives the connecting rod 33. The rotation of the connecting rod 33 causes the cam 32 to rotate. The two sides of the cam 32 respectively contact the filter net bag 3 to push the filter net bag 3 to rise or fall, causing the filter net bag 3 to vibrate. At the same time, the positioning slider 31 keeps sliding on the inner side of the positioning slide groove 23 to maintain the connection state. When a lot of garbage is piled up on the filter net bag 3, it can be shaken to prevent the garbage from clogging the filter net bag 3, making the use of the cleaning mechanism more convenient.
