[0029] Please refer to Figures 1-6 , an embodiment of a bag filter for an automatic spraying line provided by the present utility model:

[0030] A bag filter for an automatic spraying line includes a filter tank 1. The top end of the filter tank 1 is rotatably connected to a cover plate 2, and the cover plate 2 is used for opening and closing the filter tank 1. The inner wall of the filter tank 1 is fixed with a placement seat 3 by bolts. A filter bag 5 is sleeved inside the placement seat 3, and the placement seat 3 is used for placing the filter bag 5, and the filter bag 5 is used for filtering sewage; a clamping mechanism 4 is arranged at the top end of the filter tank 1 and extends into the filter tank 1 and the placement seat 3. The clamping mechanism 4 is used for clamping multiple filter bags 5 at the same time, improving the clamping and limiting efficiency of the filter bags 5. The clamping mechanism 4 includes a clamping plate 408 slidably sleeved inside the placement seat 3. One end of the clamping plate 408 is provided with a sliding block 407. One end of the sliding block 407 is provided with a pressing rod 406. One end of the pressing rod 406 is sleeved with a moving rod 405. When the moving rod 405 moves downward, it can push the pressing rod 406 to move horizontally. When the pressing rod 406 moves horizontally, it can drive the sliding block 407 to move, and when the sliding block 407 moves, it can drive the clamping plate 408 to move, thereby clamping and limiting the top end of the filter bag 5.

[0031] The clamping plate 408 is fixedly connected to the sliding block 407 by bolts. The sliding block 407 is welded to the extrusion rod 406. A moving groove is provided on the inner wall of the placing seat 3. The moving groove matches the moving track of the moving rod 405, and the moving groove is used to ensure the stable vertical movement of the moving rod 405. A limiting column 4081 is sleeved on the inner wall of the clamping plate 408. Both sides of the limiting column 4081 are fixedly connected to the inner wall of the placing seat 3 by bolts. The limiting column 4081 is used to support the clamping plate 408, thereby ensuring the stability of the horizontal movement of the clamping plate 408. An inclined through groove is provided at one end of the moving rod 405. The extrusion rod 406 is cylindrical. When the moving rod 405 moves downward, it can drive the inclined through groove to move, and then can squeeze the extrusion rod 406 to move horizontally. A connecting block 404 is provided on one side of the moving rod 405. A moving block 403 is provided at the top of the connecting block 404. The inner wall of the moving block 403 is threadedly connected to a threaded rod 402. The threaded rod 402 is rotatably connected to the inner wall of the filter tank 1 through a bearing. A moving column 401 is slidably sleeved inside the threaded rod 402. The top end of the moving column 401 penetrates above the filter tank 1. When the threaded rod 402 rotates, it can drive the moving block 403 to move downward. When the moving block 403 moves, it can drive the connecting block 404 to move downward. When the connecting block 404 moves, it can drive the moving rod 405 to move downward. The moving rod 405 is fixedly connected to the connecting block 404 by bolts, and the connecting block 404 is fixedly connected to the moving block 403 by bolts. Through the setting of this structure, the threaded rod 402 can be rotated to drive the moving block 403, the connecting block 404 and the moving rod 405 to move vertically and stably.

[0032] A boss 4011 is provided at the bottom end of the moving column 401. The boss 4011 is located inside the threaded rod 402. A ball 4012 is provided on the outer wall of the boss 4011. A spiral groove is provided on the inner wall of the threaded rod 402. The spiral groove is sleeved with the ball 4012. When the moving column 401 moves downward, it can drive the boss 4011 to move. When the boss 4011 moves, it can drive the ball 4012 to move downward. The ball 4012 moves in the spiral groove on the inner wall of the threaded rod 402. The moving column 401 is connected to the boss 4011 by bolts. The ball 4012 and the boss 4011 are rotatably connected by a connecting shaft. By connecting the ball 4012 and the boss 4011 through the connecting shaft, the ball 4012 can rotate, which is convenient for moving on the inner wall of the threaded rod 402. A connecting rod 4013 is fixedly bolted to the outer wall of the moving column 401. The bottom end of the connecting rod 4013 penetrates into the filter tank 1, and the bottom end of the connecting rod 4013 is fixedly connected to a spring 4014. The bottom end of the spring 4014 is fixedly connected to the inner wall of the filter tank 1. The spring 4014 is used to support the connecting rod 4013 and the moving column 401, thereby maintaining the initial position of the moving column 401, and the spring 4014 is used to provide a vertical movement restoring force to the moving column 401 and the connecting rod 4013.

[0033] The working principle of the present utility model is as follows: When using this device, first evenly distribute a plurality of filter bags 5 inside the placement seat 3. Then the user rotates to close the cover plate 2, and the cover plate 2 rotates and contacts the top end of the moving column 401, thereby squeezing the moving column 401 to move downward. The movement of the moving column 401 drives the movement of the boss 4011, the movement of the boss 4011 drives the movement of the ball 4012, and the ball 4012 moves and squeezes the spiral groove on the inner wall of the threaded rod 402, thereby driving the spiral groove to rotate. The rotation of the spiral groove drives the rotation of the threaded rod 402, the rotation of the threaded rod 402 drives the moving block 403 to move downward, the movement of the moving block 403 drives the movement of the connecting block 404, the downward movement of the connecting block 404 drives the movement of the moving rod 405, and the movement of the moving rod 405 squeezes the pressing rod 406 to move away from the connecting block 404. The movement of the pressing rod 406 drives the movement of the sliding block 407, the movement of the sliding block 407 drives the movement of the clamping plate 408, and the clamping plate 408 moves to the top end of the filter bag 5. At this time, the top end of the filter bag 5 is clamped and limited. While the moving column 401 moves downward, it drives the connecting rod 4013 to move downward, and the spring 4014 is squeezed by force;

[0034] Secondly, when it is necessary to take out and replace the filter bag 5 inside the placement seat 3, rotate to open the cover plate 2. Then the spring 4014 returns to its original state and drives the moving column 401 to move back. The reset movement of the moving column 401 drives the reset movement of the moving rod 405 through mechanical transmission, and the reset movement of the moving rod 405 drives the reset movement of the clamping plate 408, thereby releasing the clamping limit of the filter bag 5;

[0035] Finally, the rotation of the cover plate 2 can be used to open and close the top end of the filter tank 1. When the cover plate 2 rotates and closes, it squeezes the moving column 401 to move downward. The downward movement of the moving column 401 can drive the clamping plate 408 to move horizontally through mechanical transmission, thereby limiting and fixing the top end of the filter bag 5. Compared with the traditional method of clamping and limiting the filter bag 5 by multiple clamping plates in sequence, the workload of the staff is reduced, and the efficiency of clamping and disassembling the filter bag 5 is improved.

[0036] The above are only the embodiments of the present utility model. Common knowledge such as specific structures and characteristics known in the solution is not described in detail here. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description.
