It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] like Figure 1-5 As shown, a ceramic slurry dewatering filter press comprises a support seat 1 and a crossbeam 2 connected to each other, a thrust plate 3 fixedly connected to the support seat 1 or the crossbeam 2, a pressure plate 5 connected to the crossbeam 2 for horizontal sliding, a plurality of filter plates 4 connected to the crossbeam 2 for horizontal sliding and located between the thrust plate 3 and the pressure plate 5, a hydraulic cylinder 6 connected and fixed to the pressure plate 5 and used to push the pressure plate 5 and the filter plate 4 to move horizontally along the crossbeam 2, and each of the filter plates 4 is provided with a filter screen 401; it also includes a top support frame 8 provided on the top of the support seat 1, a support plate assembly 1 9 and a support plate assembly 2 10 connected to the top support frame 8 for horizontal sliding, and two groups of power assemblies respectively used to drive the support plate assembly 1 9 and the support plate assembly 2 10 to move horizontally, and each of the support plate assembly 1 9 and the support plate assembly 2 10 is provided with a clamping shielding assembly, and two cleaning assemblies are symmetrically provided on the clamping shielding assembly;

[0023] The cleaning component includes a vertical telescopic part 17, a gas delivery pipe 18 connected to the telescopic end of the vertical telescopic part 17, a plurality of gas nozzles 19 connected to the gas delivery pipe 18 and with the air flow output direction aligned with the filter 401, and a flexible scraper 20 provided at the bottom of the gas delivery pipe 18 and used to scrape the powder on the filter 401.

[0024] It should be noted that, in this embodiment, the gas delivery pipe 18 is connected to a compressed gas source.

[0025] Preferably, the support plate assembly 1 9 and the support plate assembly 2 10 each include two side plates that are symmetrically arranged front to back and are located at the front and back sides of the filter plate 4 respectively.

[0026] Preferably, the clamping shielding assembly includes two upper baffles 12 and lower baffles 13 respectively connected to the two side plates of the support plate assembly 1 9 or the support plate assembly 2 10 through a transverse telescopic member 11, the two upper baffles 12 are both located above the crossbeam 2 and are used to press the top of the filter plate 4 and respectively press the front and rear end surfaces of the filter plate 4, and the two lower baffles 13 are both located below the crossbeam 2 and are respectively used to press the front and rear end surfaces of the filter plate 4;

[0027] The vertical telescopic member 17 is arranged on the top of the upper baffle 12 and a moving channel 16 is opened on the top of the upper baffle 12 for the vertical telescopic member 17, the gas delivery pipe 18, the gas nozzle 19 and the flexible scraper 20 to move up and down.

[0028] It should be noted that, in this embodiment, the transverse telescopic member 11 and the vertical telescopic member 17 are any one of an electric push rod and a bamboo-type telescopic rod.

[0029] Preferably, a sealing gasket 14 is provided on the contact surface between the upper baffle 12 and the lower baffle 13 and the filter plate 4, and a pressure sensor 15 is provided on the mutual contact surface between the upper baffle 12 and the lower baffle 13 on the support plate assembly 1 9 and the support plate assembly 2 10. When the pressure sensor 15 detects pressure, it indicates that the two upper baffles 12 of the support plate assembly 1 9 and the support plate assembly 2 10 are in contact with each other, and the two lower baffles 13 of the support plate assembly 1 9 and the support plate assembly 2 10 are in contact with each other. By the two upper baffles 12 and the two lower baffles 13 contacting each other, protection is achieved between the two adjacent filter plates 4 through the two upper baffles 12 and the two lower baffles 13. When the cleaning assembly cleans the filter screen 401 of the two adjacent filter plates 4, it can play a certain protective shielding role to reduce the diffusion of powder.

[0030] Preferably, the power assembly includes two screw rods 21 rotatably connected to the top support frame 8, a nut seat 22 connected to the screw rods 21 through a ball nut pair, a synchronizer 24 provided on the two screw rods 21, and a driving member 23 provided on the top support frame 8 for driving the screw rods 21 to rotate, and the two side plates of the support plate assembly 1 9 or the support plate assembly 2 10 are respectively fixedly connected to the two nut seats 22;

[0031] It should be noted that, in this embodiment, the driving member 23 includes but is not limited to a servo motor, and may also be an integral structure consisting of a servo motor and two mutually meshing gears. When the driving member 23 is a servo motor, the output shaft of the servo motor is connected to one of the lead screws 21; when the driving member 23 is an integral structure consisting of a servo motor and two mutually meshing gears, the two gears are respectively mounted on the output shaft of the servo motor and one of the lead screws 21. When the servo motor is working, the rotation of its output shaft drives the mutually meshing gears to rotate, thereby driving the lead screw 21 to rotate.

[0032] In this embodiment, the synchronous member 24 includes two synchronous wheels respectively provided on the two screw rods 21 and a synchronous belt provided between the two synchronous wheels. The synchronous member 24 drives the two screw rods 21 to rotate together, thereby driving the two side plates of the support plate assembly 1 9 or the support plate assembly 2 10 and the components provided on the side plates to move together.

[0033] Preferably, a receiving box 7 is placed below the thrust plate 3 , the filter plate 4 and the pressing plate 5 to receive powder dropped from the filter screens 401 of two adjacent filter plates 4 .

[0034] When in use, the powder after dehydration and filtration treatment will be compressed and squeezed between the filter screens 401 of the two adjacent filter plates 4. After the two adjacent filter plates 4 are separated, the powder compressed and squeezed between the filter screens 401 of the two adjacent filter plates 4 will fall into the inside of the support seat 1, but a small amount of powder will adhere to the filter screens 401 of the filter plates 4. At this time, the filter screen 401 can be cleaned by the cleaning component. The specific usage method is to drive the support plate component 9 to move through one of the power components, and then start the four horizontal telescopic members 11 on the support plate component 9. The four horizontal telescopic members 11 are extended in length to drive the two symmetrically arranged upper baffles 12 to approach each other to press against the top and front and rear end surfaces of one of the filter plates 4, and the two lower baffles 12. The baffles 13 are close to each other to press against the front and rear end surfaces of the filter plate 4, thereby clamping and fixing the filter plate 4, and then another power component drives the support plate assembly 2 10 to move, and then the four transverse telescopic members 11 on the support plate assembly 2 10 are started. The four transverse telescopic members 11 are extended in length to drive the two symmetrically arranged upper baffles 12 to approach each other to press against the front and rear end surfaces of the filter plate 4 adjacent to one of the filter plates 4, and the two lower baffles 13 are close to each other to press against the front and rear end surfaces of the filter plate 4, thereby clamping and fixing the filter plate 4, and then another power component continues to drive the support plate assembly 2 10 to move a distance toward the pressing plate 5, so that the two adjacent filter plates 4 can be separated. There is a certain distance between the two adjacent filter plates 4. At this time, most of the powder on the filter screens 401 of the two adjacent filter plates 4 will fall down, and then adjust the position of the support plate assembly 1 9 and the support plate assembly 2 10, that is, make the support plate assembly 1 9 and the support plate assembly 2 10 move closer to each other, so that the upper baffles 12 on the support plate assembly 1 9 and the support plate assembly 2 10 can contact each other, and the lower baffles 13 on the support plate assembly 1 9 and the support plate assembly 2 10 can contact each other, that is, when the pressure sensor 15 detects pressure, stop adjusting the position of the support plate assembly 1 9 and the support plate assembly 2 10, and then make the upper baffles 12 and the lower baffles 13 on the support plate assembly 1 9 and the support plate assembly 2 10 respectively clamped between the two adjacent filter plates 4. On the front and rear end surfaces, the four upper baffles 12 and the four lower baffles 13 can be used to block the front and rear sides and the top of the two adjacent filter plates 4, that is, only the bottoms of the two adjacent filter plates 4 are left with a material dropping channel, and then the vertical telescopic parts 17 of the two cleaning components are started, and the vertical telescopic parts 17 drive the gas delivery pipe 18, the gas nozzle 19, and the flexible scraper 20 to move downward, and the flexible scraper 20 contacts the filter screen 401, scrapes off the powder adhered to the filter screen 401, and then the filter screen 401 is cleaned by the airflow ejected by the gas nozzle 19. Through the blocking and blocking of the four upper baffles 12 and the four lower baffles 13, when cleaning the powder, it can reduce the diffusion of the powder, so that the production workshop maintains a better air environment.

[0035] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
