Description

Technical Field

[0002] Catalysts are commonly used auxiliary agents in production, which can accelerate the reaction and improve production efficiency. During the production and preparation process of catalysts, the catalysts need to be filtered to remove impurities in the preparation tank and impurities contained in the catalyst itself. The catalyst filtration system is mainly composed of filters. During the use of the filters, the filter element needs to be replaced regularly to ensure that the filter can work normally. If the filter element is not replaced, the filter will be blocked and normal filtering work will not be possible. In the actual production process, the replacement of the filter element is relatively troublesome. It requires the disassembly of the equipment and then the replacement and installation of the filter element. The installation of the filter element is relatively cumbersome. This process requires more manpower, which invisibly increases the work intensity of the staff. In addition, during the replacement of the filter element, the entire filtration system needs to be in a shutdown state for a long time until the filter element replacement is completed. It can work again, which seriously affects the production efficiency of the catalyst. Summary of the Invention

[0039] When filtering the catalyst, the sealing movable sleeve 4 is connected to one of the filter cartridges to transport and filter the catalyst. When the filter element 5 in the used filter cartridge needs to be replaced, the delivery pipe 33 can be closed by the solenoid valve, and the sealing movable sleeve 4 is pushed upward to make it exit the center socket 61. At this time, the motor 2 can be started to drive the movable conveying plate 3 to move toward the other filter cartridge under the action of the thread. At the same time, the circular cover 7 on the previously used filter cartridge is reset under the action of the second reset spring 73 and covers the center socket 61 again. As the movable conveying plate 3 moves, the sealing movable sleeve 4 is lifted upward under the action of the inclined push claw 62 , move to the upper end of the other sealing protection cover plate 6, contact the circular cover plate 7 at its upper end, and then push the circular cover plate 7 away from the central insertion hole 61. When the sealing movable sleeve 4 is aligned with the central insertion hole 61, it is plugged into the central insertion hole 61 to realize automatic connection with the filter cartridge. At this time, the catalyst can continue to be transported and filtered, which is very convenient and avoids the long-term shutdown of the filtration system. Then, the filter element 5 in the other filter cartridge can be replaced at this time, that is, the locking sleeve 641 is pressed downward at this time, so that the protruding locking block 93 exits the locking through hole 642, and then resets under the action of the first reset spring 661. During the reset process, the arc limit block 68 conflicts with the end plate. Then the elastic limiting plate 67 is deformed upward until it passes over the end plate, and the elastic limiting plate 67 recovers its deformation so that the flat end of the arc limiting block 68 is stuck on the end plate, thus preventing the sealing protection cover plate 6 from reciprocating under the action of the first return spring 661. As the sealing protection cover plate 6 is reset, the pushed rotating block 8 is also reset under the action of the third return spring 83, and then the sector gear 94 is driven to reset under the action of the meshing teeth 82, and at the same time, the semi-circular ring locking piece 87 is rotated to the lower end of the semi-circular ring groove 52, thereby unlocking the filter element 5 and taking it out for replacement. After the new filter element 5 is placed, the elastic limiting plate 67 is lifted upward. The arc limit block 68 is no longer stuck on the end plate, and then the sealing protection cover plate 6 is pushed to cover the port of the filter cartridge. During this process, the friction-reducing wheel 65 will contact the pushed rotating block 8, pushing it to rotate, and then drive the semi-circular ring locking piece 87 to rotate into the semi-circular ring groove 52, thereby fixing the filter element 5. At the same time, when the protruding locking block 93 is rotated downward and pressed into contact with the locking sleeve 641, the locking sleeve 641 is pressed downward until the protruding locking block 93 is aligned with the locking through hole 642, and then the locking sleeve 641 is driven to move upward under the action of the second connecting spring 644, so that the protruding locking block 93 is inserted into the locking through hole 642, thereby fixing the sealing protection cover plate 6, which is very convenient.
