The filter plate 32 includes a circular plate 321 and a plurality of filter holes 322 arranged in a square array opened on the circular plate 321. The outer side of the circular plate 321 is sleeved with a square frame 323, which is fixed to the bottom of the kettle body 2 and fixedly connected to the inner wall of the filtration box 31. In this way, the kettle body 2 and the filter plate 32 can be kept sealed with each other, while maintaining the sealing of the filtration process, and at the same time, the sealing of the opening and closing module 4 can be met.

[0025] The opening and closing module 4 includes a guide component 41 and a sealing component 42. The guide component 41 includes a limiting groove 411 provided on the outer wall of the locking block 36. Each limiting groove 411 is connected with a guide rod 412.

The bottom of the pressure plate 52 is abutted against two connecting plates 53, and each connecting plate 53 can lift the pressure plate 52 under the action of rotation, thereby changing the height of the filter plate 32, and the bottom of each connecting plate 53 is connected to a connecting block 55 through a rotating shaft 54. The outer wall of the locking block 36 is provided with a number of vertical grooves 56 equal to the number of connecting frames 51, and the movement of the connecting frames 51 is limited by the vertical grooves 56. The plurality of connecting frames 51 are slidably connected in the vertical grooves 56 and the top is connected to the top of the vertical grooves 56 by a spring, which plays a buffering role.

When the mounting plate 421 moves, the connecting block 55 can be driven to move simultaneously. The two connecting blocks 55 are connected together with a slide rail 58 to limit the moving direction of the connecting block 55. The slide rail 58 is fixed on the outer wall of the locking block 36. The connecting frame 51 adopts a right-angle elbow structure. Multiple connecting frames 51 are arranged at equal distances. Shoulder plates are arranged on both sides of the filter plate 32, and the shoulder plates are sealingly slidably connected to the inner wall of the suction filter box 31 to play a sealing role to avoid affecting the normal sedimentation and filtration work. A limiting shaft 59 is connected to the top of each connecting plate 53, and a connecting groove 510 is connected to the outer side of the limiting shaft 59. The connecting groove 510 is opened on the outer wall of the locking block 36 and the limiting shaft 59 is vertically slidably connected in the connecting groove 510. The limiting shaft 59 is used to limit the activity of the top of the connecting plate 53 so that it can only move in the vertical direction.

[0027] The cleaning module 6 includes a plurality of gears 61 arranged on both sides of the filter plate 2 33. The filter plate 2 33 includes a plurality of support plates 331 and a frame 332. The gaps between the plurality of support plates 331 constitute a filter port 334. Both sides of each support plate 331 are rotatably connected to the inner side of the frame 332 through a rotating shaft 1 333. In this way, the support plate 331 can rotate. The rotating shaft 1 333 is coaxially connected to the gear 61 on one side outside the frame 332. The same number of racks 62 are arranged below the plurality of gears 61. The racks 6 The number of teeth of gear 2 is 1 / 2 of that of gear 61. After horizontal movement, vertical movement, and reverse horizontal movement, gear 61 meshes with rack 62 and causes gear 61 to rotate 180°, just so that the upper working surface of support plate 331 rotates to the lower side after the support plate 331 rotates. Rack 62 is fixed on the inner wall of locking block 36. Rotating shaft 1 333 is frictionally connected with frame 332 and a torsion spring is provided at the connection. After gear 61 is disengaged from the meshing with rack 62, it will rotate in the reverse direction to the initial state, thereby playing the role of flipping and shaking the material.

[0028] When the present invention is in use, when a precipitation reaction is carried out, the passage formed by the filter plate 1 32 and the filter plate 2 is in a closed state, and the precipitation reaction can be carried out in the reactor at this time, so that the solid precipitate will not be discharged through the passage. When the precipitation filtration work is carried out, the liquid in the filtration box 31 is extracted through the suction pipe 34 and the external filtration system to realize the collection of the precipitate;

[0029] During the above switching operation, the guide rod 412 connected to the filter plate 2 33 controls the moving direction through the limit groove 411, referring to Figure 6 The guide rod 412 first translates a short distance toward the left side from the first working point, then moves vertically downward for a distance, then translates in the opposite direction to the rightmost end, then moves vertically upward, and finally moves left to the second working point. The design function of the limit groove 411 is that since the filter plate 1 32 and the filter plate 2 33 are against each other, direct translation for a distance will cause greater friction between the two, which will affect the sealing effect between the two when they are stationary and affect the service life. The designed limit groove 411 can reduce the moving distance of the friction. However, since it is still necessary to translate for a distance, the anti-friction module 5 is designed in the present invention. When the filter plate 1 32 moves to the left, it will drive the left side through the mounting plate 421 The connecting block 55 moves to the left. Since the connecting block 55 is rotatably connected to the connecting plate 53, and the upper side of the connecting plate 53 is limited by the connecting groove 510, an upward force will be generated when the connecting block 55 moves to the left. This force acts on the pressure plate 52, and the filter plate 1 32 will be driven to move up a short distance through the connecting frame 51. Therefore, within a certain distance when the connecting block 55 moves to the left, no friction will be generated between the filter plate 1 32 and the filter plate 2 33. When the connecting block 55 moves to the leftmost position, the connecting plate 53 will be in a position symmetrical to the original state, so that the top of the connecting plate 53 will drop to the initial position, that is, the filter plate 1 32 returns to the initial position.

[0030] Similarly, when the mounting plate 421 moves to the uppermost end on the right side, the leftward movement of the mounting plate 421 will drive the leftward movement of the connecting block 55 on the right side, which will cause the connecting plate 53 on the right side to drive the filter plate 1 32 to move upward. In this way, during the overall movement of the guide rod 412, no friction will be generated between the filter plates 1 32 and 33. When the guide rod 412 is located at the lower part of the limiting groove 411 and translates, it will drive the gear 61 and the rack 62 on the filter plate 2 33 to act, so that the multiple rotating shafts 1 54 drive the multiple supporting plates 331 to rotate. In this way, the working surface of the filter plate 2 33 can be rotated to the lower side at this moment, so as to remove impurities between the two filter plates, thereby improving the service life of the device, reducing cleaning, and facilitating use.

[0031] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
