[0023] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0024] The embodiment of the present application provides an alkali filter with a vacuum box in a cloth area that can be quickly replaced, comprising a support frame 30 and two vacuum box bodies 10 that cooperate with filter belts 50 of the alkali filter, a vent pipe 11 being provided at one end of the vacuum box body 10, a friction ring 20 being detachably connected to the outside of the vacuum box body 10, the friction ring 20 being water-permeable and air-permeable, an external vacuum pumping device evacuates the inside of the vacuum box body 10 through the vent pipe 11 to form a negative pressure, and a gap for ventilation is provided on the outside of the vacuum box body 10;

[0025] The support frame 30 includes a support rod 31 installed on the alkali filter machine, and the top of the support rod 31 is rotatably connected to a mounting frame 33. Two vacuum box bodies 10 are installed on the side of the mounting frame 33 away from the support rod 31. The rotation axis 34 of the mounting frame 33 is perpendicular to the support rod 31. The ventilation pipe 11 is arranged on the side of the vacuum box body 10 away from the mounting frame 33. A locking mechanism 40 for locking the position of the mounting frame 33 is arranged between the support rod 31 and the mounting frame 33. When one of the vacuum box bodies 10 is being used to cooperate with the filter belt 50 of the alkali filter machine, the other vacuum box body 10 is idle and away from the filter belt 50 of the alkali filter machine.

[0026] The following is a further introduction based on specific usage scenarios.

[0027] When in use, the operator unlocks the locking mechanism 40, rotates the mounting frame 33 to make one of the vacuum box bodies 10 contact the filter belt 50 of the alkali filter machine, and makes the other vacuum box body 10 move away from the filter belt 50 of the alkali filter machine, and then locks the position of the vacuum box body 10 through the locking mechanism 40, turns on the external vacuum pumping equipment and vacuums the inside of the vacuum box body 10 through the ventilation pipe 11 to form a negative pressure, and when the filter belt 50 of the alkali filter machine rotates outside the friction ring 20, the moisture on the filter belt passes through the friction ring 20 and the vacuum box body 10.

[0028] When the friction ring 20 or the vacuum box body 10 needs to be replaced or maintained, the operator unlocks the locking mechanism 40, rotates the mounting frame 33 to make another ready vacuum box body 10 contact the filter belt 50 of the alkali filter machine, and moves the vacuum box body 10 that needs to be replaced or maintained away from the filter belt 50 of the alkali filter machine, so that the alkali filter machine continues to work. The operator can then replace or maintain the vacuum box body 10 that is away from the filter belt 50 of the alkali filter machine. This process does not require shutdown operations, thereby reducing the working time of the alkali filter machine required for replacement and maintenance of the vacuum box body 10, and significantly improving the working efficiency of the alkali filter machine.

[0029] The friction ring 20 is detachably connected to the vacuum box body 10 , and the operator can quickly perform maintenance on the vacuum box body 10 and the friction ring 20 by quickly disassembling the friction ring 20 .

[0030] In general, the embodiment of the present application is in the form of two vacuum box bodies 10. When one of the vacuum box bodies 10 needs maintenance, there is always a ready vacuum box body 10 that can be put into use immediately, which reduces the downtime required for maintenance of the equipment and significantly improves the working efficiency of the alkali filter.

[0031] In the embodiment of the present application, the friction ring 20 is detachably connected to the vacuum box body 10. The embodiment of the present application provides a possible specific implementation method. The friction ring 20 includes a rectangular friction belt 21, a card slot 22 is provided on one side of the friction belt 21, and a buckle 23 that can cooperate with the card slot 22 is provided on the other side of the friction belt 21. The friction belt 21 is sleeved on the outside of the vacuum box body 10, and the buckle 23 at one end of the friction belt 21 is inserted into the card slot 22 at the other end to complete the assembly, thereby forming a ring-shaped friction ring 20. When in use, the operator disassembles It is convenient to disassemble and assemble the friction ring 20, which improves the maintenance efficiency of the operator. The cross-sections of the groove 22 and the buckle 23 are both L-shaped. When the diameter of the friction ring 20 undergoes elastic deformation and increases in diameter, the buckle 23 and the groove 22 are locked more tightly. When the diameter undergoes elastic deformation and decreases in diameter, the operator can easily separate the buckle 23 from the groove 22. During operation, the friction ring 20 rotates on the outside of the vacuum box with the filter belt 50 of the alkali filter, causing a loose edge to increase its diameter, thereby making the buckle 23 and the groove 22 tightly connected.

[0032] In the embodiment of the present application, the mounting bracket 33 is rotatably connected to the top of the support rod 31, and the rotation axis 34 of the mounting bracket 33 is perpendicular to the support rod 31, wherein a rotation axis 34 is fixedly connected to the side of the mounting bracket 33 close to the support rod 31, and the rotation axis 34 passes through the support rod 31 and is rotatably connected to the support rod 31, thereby realizing the rotation connection between the mounting bracket 33 and the support rod 31.

[0033] The locking mechanism 40 is used to lock the position of the mounting bracket 33, thereby locking the relative positions of the two vacuum box bodies 10 and the respective working states of the two vacuum box bodies 10. The embodiment of the present application provides a locking method. A countersunk hole 35 is provided at one end of the rotating shaft 34 away from the mounting bracket 33, and a connecting key 36 is arranged in the countersunk hole 35. The locking mechanism 40 includes a connecting rod 41. A connecting groove 42 that cooperates with the connecting key 36 is provided on the connecting rod 41. One end of the connecting rod 41 can slide in the countersunk hole 35 of the rotating shaft 34. When the connecting groove 42 on the connecting rod 41 cooperates with the connecting key 36, the axial rotation of the connecting rod 41 will also drive the mounting bracket 33 to rotate synchronously through the rotating shaft 34. The connecting rod 41 is far away from the mounting bracket 33. A push rod 43 is provided at one end away from the rotating shaft 34, and a locking groove 32 for placing the push rod 43 is opened on the side of the support rod 31 away from the mounting bracket 33. When the push rod 43 is located in the locking groove 32, the inner wall of the locking groove 32 limits the axial rotation of the push rod 43. When in use, the operator pulls the push rod 43 sideways to make the push rod 43 disengage from the locking groove 32, and then the operator rotates the push rod 43 to adjust the angle of the mounting bracket 33 so that the determined vacuum box body 10 is in a predetermined working position. After the adjustment is completed, the operator resets the push rod 43 to make the push rod 43 re-enter the locking groove 32. The inner wall of the locking groove 32 contacts the outer side of the push rod 43 to form a rigid limit to prevent the mounting bracket 33 from axial rotation. The operation is simple and efficient.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
