Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a device for quickly replacing filter bags in multiple bag filters. Background Technology

[0002] The erythritol production process involves multiple bag filters, resulting in long filter bag cleaning times per shift. This is because the dirty filter bags can only be removed and cleaned after all the material in each bag filter has been drained. Since there are no discharge ports on the filters, employees can only discharge the material one cup at a time from the bag filter's loading port using plastic cups, which is inefficient. Therefore, we have proposed a device for quickly replacing filter bags in multiple bag filters to solve the above problems. Utility Model Content

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a device for quickly replacing filter bags in multiple bag filters.

[0025] Reference Figure 1-5 A device for quickly replacing filter bags of multiple bag filters includes multiple bag filters 101. An mounting plate 102 is fixedly installed on the top outer side of each bag filter 101. A cover plate 103 is installed on the top of the mounting plate 102 through a detachable structure. A fixing sleeve 201 is welded to the front side of each bag filter 101. The fixing sleeve 201 is connected to the corresponding bag filter 101. A discharge pipe 202 is installed inside the fixing sleeve 201. A rotating shaft 301 is rotatably installed on the top and bottom inner walls of the discharge pipe 202. The same sealing plate 302 is fixedly installed at the end of the two rotating shafts 301 that are close to each other. The sealing plate 302 is adapted to the discharge pipe 202. A housing 303 is fixedly installed on the top of the discharge pipe 202. A drive mechanism connected to the rotating shaft 301 is provided inside the housing 303. A rotating hole is opened on the top inner wall of the discharge pipe 202, and the rotating shaft 301 is rotatably connected to the corresponding rotating hole.

[0026] In this embodiment, the drive mechanism includes a worm gear 401, a worm 403, a drive shaft 402, and a handwheel 404. The top end of the rotating shaft 301 extends into the housing 303 and is fixedly mounted with the worm gear 401. The same drive shaft 402 is rotatably mounted on the inner walls of both sides of the housing 303. One end of the drive shaft 402 extends to the outer side of the housing 303 and is fixedly mounted with the handwheel 404. The worm 403 is fixedly mounted on the drive shaft 402, and the worm 403 meshes with the worm gear 401. This drive mechanism utilizes the meshing transmission of the worm gear 401 and the worm 403, and has a self-locking function. It can ensure that the position of the sealing plate 302 is stable after the discharge pipe 202 is opened or closed, and prevent the sealing plate 302 from rotating on its own due to accidental external forces, thereby ensuring the sealing performance of the discharge pipe 202 in the working state and the stability in the non-working state.

[0027] In this embodiment, a positioning mechanism is provided between the discharge pipe 202 and the fixing sleeve 201. A fixing mechanism is provided on the fixing sleeve 201, and the fixing mechanism is adapted to the discharge pipe 202. The positioning mechanism includes a positioning groove 601 and a positioning seat 602. Positioning grooves 601 with one open side are provided on the top and bottom inner walls of the fixing sleeve 201. Positioning seats 602 are fixedly installed on the top and bottom of the discharge pipe 202, and the positioning seats 602 are adapted to the corresponding positioning grooves 601. The positioning mechanism enables the discharge pipe 202 to quickly and accurately find its position during installation, greatly improving installation efficiency, and also ensuring the coaxiality of the connection between the discharge pipe 202 and the fixing sleeve 201.

[0028] In this embodiment, the fixing mechanism includes a fixing groove 501, a bolt hole 502, and a fixing bolt 503. The top and bottom of the discharge pipe 202 are both provided with fixing grooves 501, and the inner wall of the fixing sleeve 201 is provided with bolt holes 502. A fixing bolt 503 is threaded into the bolt hole 502, and the fixing bolt 503 is adapted to the corresponding fixing groove 501. The fixing mechanism uses a bolt-fixing groove 501 connection, which is simple in structure and firmly connected. When maintenance or replacement of the discharge pipe 202 is required, the discharge pipe 202 can be easily disassembled and installed simply by rotating the fixing bolt 503, making the operation convenient.

[0029] In this embodiment, multiple U-shaped connecting seats 701 are fixedly installed on the outer side of the mounting plate 102, and multiple U-shaped fixing seats 702 are fixedly installed on the outer side of the cover plate 103. A locking mechanism is provided between the U-shaped connecting seats 701 and the U-shaped fixing seats 702. The locking mechanism includes a rotating shaft 703, a threaded rod 704, a nut 705, and a handle 706. The same rotating shaft 703 is rotatably installed on both sides of the U-shaped connecting seat 701. A threaded rod 704 is fixedly installed on the rotating shaft 703, and a nut 705 is threaded onto the threaded rod 704. The nut 705 is adapted to the U-shaped fixing seat 702, and a handle 706 is fixedly installed on the top of the nut 705. This locking mechanism enables the nut 705 to move on the threaded rod 704 by rotating the handle 706, thereby achieving rapid locking and unlocking of the cover plate 103.

[0030] In this invention, when the filter bag of the bag filter 101 needs to be replaced, the inlet and outlet valves of the bag filter 101 are closed. By turning the handwheel 404, the handwheel 404 drives the worm gear 403 to rotate via the drive shaft 402. The worm gear 403 drives the worm wheel 401 to rotate, and the worm wheel 401 drives the rotating shaft 301 and the sealing plate 302 to rotate. This opens the discharge pipe 202, allowing the material inside the bag filter 101 to be emptied. This avoids the situation where employees can only discharge the material one cup at a time from the filter bag opening of the bag filter 101. By turning the handle 706 and the nut 7... 05. The U-shaped fixing seat 702 can be released from compression. By rotating the threaded rod 704, the threaded rod 704 can bring the nut 705 to rotate the top of the U-shaped fixing seat 702 to one side, thereby allowing the cover plate 103 to be disassembled and installed, and the filter bag in the bag filter 101 to be replaced. By rotating the fixing bolt 503, under the action of the threaded hole, the fixing bolt 503 can be rotated and moved at the same time. The fixing bolt 503 can be inserted into or released from the corresponding fixing groove 501, thereby achieving the purpose of fixing and releasing the discharge pipe 202, and achieving the purpose of disassembling, maintaining or replacing the discharge pipe 202.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
