Technical Field
[0001] This utility model relates to the field of filter cloth replacement technology, specifically a space-saving automatic filter cloth replacement device for vacuum filters. Background Technology
[0002] In numerous industrial sectors such as chemical, mining, and food processing, vacuum filters have become indispensable key equipment in production processes due to their highly efficient solid-liquid separation capabilities. As the core component of a vacuum filter for solid-liquid separation, the filter cloth experiences reduced filtration efficiency and deteriorated separation effects over long-term use due to material blockage, fiber wear, and chemical corrosion. Therefore, it needs to be replaced regularly.
[0003] The prior art discloses a filter cloth replacement device for a filter press, with publication number CN221020821U, belonging to the field of filter press technology. This filter cloth replacement device includes a platform structure with a flat plate extending horizontally; an extension structure, a clamping structure, and a pushing structure. By setting up the platform structure, the platform portion of the platform structure serves as an assembly platform for the filter cloth and filter elements. The extension structure, the clamping structure mounted on the extension structure, and the pushing structure are installed based on the platform structure. The clamping structure clamps the open end of the filter element and keeps the opening of the filter element in an open state. The pushing component of the pushing structure enters from the open end of the filter element and acts on the filter element inside the filter cloth.
[0004] The aforementioned space-saving automatic filter cloth replacement device for vacuum filters moves the filter fan from the open end to the outlet end of the filter cloth under the action of the pushing component, and makes close contact with the filter cloth to realize the assembly of the filter cloth and filter fan, thus achieving automation of the assembly. However, the aforementioned filter cloth replacement device is not suitable for filter cloths of different thicknesses, and its adaptability during replacement is poor, resulting in poor performance during use. Improvements are needed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 The present invention provides the following technical solution: A space-saving automatic filter cloth replacement device for vacuum filters includes a support platform 1, a placement seat 2 on the top of the support platform 1, a filter cloth storage and release component 3 on the top of the support platform 1, and a release limiting component 4 on the surface of the filter cloth storage and release component 3.
[0020] The release limit assembly 4 includes a connecting plate 401. A connecting frame 402 is fixedly connected to the front of the connecting plate 401. A hydraulic telescopic rod 403 is fixedly connected to the top of the connecting frame 402. A connecting slider 404 is fixedly connected to the bottom of the hydraulic telescopic rod 403. A connecting bracket 405 is fixedly connected to the back of the connecting slider 404. A rectangular frame base 406 is fixedly connected to the bottom of the connecting bracket 405. Elastic pads 407 are fixedly connected to both sides inside the rectangular frame base 406. An inner sponge column is fixedly connected inside the elastic pad 407. Part 408, an airbag 409 is fixedly connected to the top of the inside of the rectangular frame base 406, an air pump 410 is fixedly connected to the top of the rectangular frame base 406, a delivery air pipe 411 is fixedly connected to the front of the air pump 410, and the end of the delivery air pipe 411 away from the air pump 410 is fixedly connected to the top center of the airbag 409. The width of the connecting slider 404 is adapted to the distance between the left and right ends inside the connecting frame 402. The connecting slider 404 is slidably connected inside the connecting frame 402. The connecting plate 401 is fixedly connected to the side of the support plate 301.
[0021] The filter cloth storage and release assembly 3 includes a support plate 301, a side limiting plate 302, a motor component 303, a storage cylinder 304, a first gear 305, a right connecting plate 306, a release cylinder 307, a second gear 308, an insertion locking block 309, a connecting rod 310, and a handle 311. A connecting base is fixedly connected to the top front of the support platform 1. The support plate 301 is fixedly connected to the top of the connecting base. The motor component 303 is fixedly connected to the right side of the side limiting plate 302. The first gear 305 is fixedly connected to the right side of the storage cylinder 304. The right connecting plate 306 is fixedly connected to the top right side of the support platform 1 near the front. The second gear 308 meshes with the first gear 305. The insertion locking block 309 is inserted into the interior of the second gear 308. The connecting rod 310 is slidably connected to the right connecting plate 306. Inside the 06, the handle 311 is fixedly connected to the right side of the connecting rod 310. The right connecting plate 306 has a through groove with a diameter that matches the diameter of the connecting rod 310. The groove allows the connecting rod 310 to pass through, allowing the locking block 309 to engage with the second gear 308 for locking. This locking ensures the normal operation of the device when winding and releasing are not required. The output shaft of the motor 303 is fixedly connected to a rotating shaft, and the storage cylinder 304 is fixedly connected to the surface of the rotating shaft. Starting the motor 303 drives the rotating shaft to rotate, which in turn drives the storage cylinder 304 to rotate. The rotating shaft serves to support the storage cylinder 304 and the release cylinder 307. A bearing is fixedly connected to the left side of the right connecting plate 306, and the rotating shaft is fixedly connected to the inner ring of the bearing.
[0022] In use, the storage cylinder 304 can be used to store the filter cloth. After fixing the head end, the motor 303 can be started to drive the rotating shaft to rotate, which in turn drives the storage cylinder 304 to rotate for winding. A first gear 305 is provided on the right side, and a second gear 308 is meshed at the bottom of the first gear 305. Therefore, the rotation of the second gear 308 can drive the release cylinder 307 below to rotate. Since the two are connected by gear meshing, their rotation directions are opposite. Therefore, when the upper storage cylinder 304 is winding, the lower release cylinder 307 can release the filter cloth. New filter cloth is released, and at the same time, the gear set drives the release cylinder 307 to rotate clockwise to collect the old filter cloth. The storage and release of new and old filter cloths are completed simultaneously, completing the filter cloth replacement process. A release limit component 4 is provided on the front of the support plate 301. It can limit the transmission of filter cloth and adjust the thickness of the insertion locking block 309 according to the thickness of the filter cloth. In use, the hydraulic telescopic rod 403 can be activated to drive the connecting slider 404 to slide and adjust the position of the rectangular frame 406 to be flush with the top of the release cylinder 307 behind, ensuring stable release. An air bladder 409 is set inside the rectangular frame 406. In use, the air pump 410 can be activated in conjunction with the air delivery pipe 411 to input gas into the air bladder 409, so that the air bladder 409 inflates and expands, reducing the distance from the bottom of the air bladder 409 to the bottom of the rectangular frame 406, thereby adapting to the release of filter cloths of different thicknesses. An elastic pad 407 and an inner sponge column 408 are set on the side to reserve space for the expansion of the air bladder 409, which can adapt to the transmission and release of filter cloths of different thicknesses, with high adaptability.
