[0026] The filtering mechanism 3 includes a filter disc 31 slidably mounted inside the support plate 12, a plurality of filter screens 32 with different accuracy levels are symmetrically arranged on the top of the filter disc 31, a plurality of conical cylinders 33 are threadedly connected to the bottom of the filter disc 31, and the conical cylinders 33 are located below the filter screens 32; the filter screens 32 filter the material squeezed by the filter press assembly 21, and allow the filtered solution to enter the conical cylinders 33, and the filter disc 31 can rotate, so that the filter screens 32 can be cleaned by the nozzle 25 immediately after filtering.

[0027] The power mechanism 4 includes a lifting assembly 41 fixedly mounted inside the base 13, a lifting plate 413 fixedly mounted on the upper output end of the lifting assembly 41, a servo motor 42 fixedly mounted above the lifting plate 413, the output end of the servo motor 42 is coaxially fixedly connected to the filter disc 31, a delivery pump 43 is provided at the side end of the base 13, the delivery pump 43 is fixedly connected to the bottom of the conical cylinder 33 on one side through a filtrate pipe 44, and the delivery pump 43 is fixedly connected to the filter press assembly 21 on the other side through a liquid delivery pipe 45, a control panel 46 is provided on one side of the base 13, and a collecting pipe 47 is provided at the bottom of the conical cylinder 33 on the other side. The lifting assembly 41 can lift the filter disc 31 so that the filter disc 31 is tightly connected to the filter press assembly 21, and the servo motor 42 above the lifting plate 413 can drive the filter disc 31 to rotate, so that the filter screen 32 is separated from the bottom of the filter press assembly 21 and is located below the nozzle 25, so that the filter screen 32 can be cleaned.

[0028] A limiting groove 121 is provided in the middle of the support plate 12, and a filter disc 31 is slidably mounted in the limiting groove 121, and the filter disc 31 is coaxial with the limiting groove 121. The limiting groove 121 is used to limit the movement of the filter disc 31, and the coaxial arrangement ensures that the filter disc 31 will not be eccentrically opposite to the filter press assembly 21 when rotating.

[0029] The filter press assembly 21 includes a filter press chamber 211 fixedly mounted inside the filter press frame 11, the top of the filter press chamber 211 is connected to the air pressure pipe 24, a spring 212 is fixedly mounted on the top of the inner wall of the filter press chamber 211, a piston 213 is fixedly mounted on the other end of the spring 212, a sealing ring 214 is arranged on the outside of the piston 213, a feed inlet 215 is arranged in the middle of the filter press chamber 211, a solenoid valve 216 is arranged on the outside of the feed inlet 215, and an annular sealing seat 217 is arranged at the bottom of the filter press chamber 211. After the air pressure is filled in the filter press chamber 211, the air pressure in the filter press chamber 211 will increase, thereby pushing the piston 213 to move downward, and at the same time pulling the spring 212 to stretch, thereby squeezing the material inside the filter press chamber 211, accelerating the filtration speed, and after the air pressure in the filter press chamber 211 is released, the piston 213 is restored under the action of the spring 212.

[0030] The filter disc 31 is symmetrically provided with a collecting drawer 311, and the filter disc 31 is symmetrically provided with a filter chamber 312, which is coaxially opposite to the filter press bin 211. A filter screen 32 is provided at the top of the filter chamber 312, and a conical cylinder 33 is provided at the bottom of the filter chamber 312. A partition 313 is provided between the filter screens 32. Air pressure is generated in the filter press bin 211 to squeeze the material, so that the filtrate passes through the filter screen 32 and enters the filter chamber 312, and then enters the conical cylinder 33. After the filter disc 31 rotates, the filter chamber 312 is located below the water tank 22. After the nozzle 25 sprays water, the filter screen 32 is rinsed. The partition 313 is provided so that when the filter screen 32 is cleaned, due to the different apertures of the filter screen 32, the filter residue is prevented from moving to another filter screen 32, resulting in clogging of the filter screen 32.

[0031] The filter screen 32 is arched and is located above the filter cavity 312. The filter screen 32 is located above the filter cavity 312, which prevents the filter residue from accumulating on the filter screen 32 and being unable to be discharged, while the arched filter screen 32 can help the filter residue to be washed away faster.

[0032] The lifting assembly 41 includes guide columns 411 vertically arranged on both sides of the base 13, a fixed plate 412 is fixedly installed between the two guide columns 411, and a lifting plate 413 is also slidably installed between the two guide columns 411, and the lifting plate 413 is located above the fixed plate 412, and a cylinder 414 is fixedly installed below the fixed plate 412, and the output end of the cylinder 414 passes through the fixed plate 412 and is fixedly installed below the lifting plate 413, and push rods 415 are arranged on both sides of the lifting plate 413, and the push rods 415 are movably connected to the bottom of the filter plate 31. When the filter disc 31 is lifted, the cylinder 414 pushes the lifting plate 413 to move, and the lifting plate 413 pushes the filter disc 31 upward through the push rod 415 and the servo motor 42, so that the filter disc 31 fits with the bottom of the filter press chamber 211, thereby performing the filtration process. During the cleaning process, the lifting plate 413 descends, and under the action of the servo motor 42, the filter disc 31 is driven to rotate. After the filter disc 31 rotates, the filter screen 32 is located below the water tank 22, and the filter screen 32 can be cleaned when the nozzle 25 sprays water.

[0034] The air pump 23 of the present invention is also provided with a solenoid valve 216;

[0035] The filtrate tube 44, the infusion tube 45, and the collection tube 47 of the present invention are all soft tubes, and have a margin for movement;

[0036] The control panel 46 of the present invention uses an external power supply, and the electrical components are all electrically connected to the control panel 46;

[0037] The filter press assembly 21 of the present invention is divided into a primary filter press and a secondary filter press, and the pore size of the filter screen 32 corresponding to the primary filter press is larger than the pore size of the filter screen 32 of the secondary filter press;

[0038] The sealing seat 217 of the present invention is made of rubber;

[0039] When the piston 213 of the present invention is not in operation, the bottom height of the piston 213 is higher than the height of the feed port 215.

[0040] The air pump 23 of the present invention is also provided with a corresponding pressure relief valve;

[0041] The nozzle 25 of the present invention is an electric nozzle 25;

[0042] The filter press chamber 211 of the present invention is provided with a transparent observation window on the upper part thereof for observing the retraction of the spring 212;

[0043] A water inlet is provided above the water tank 22 of the present invention.

[0044] Example 3

[0045] Instructions for use: When squeezing and filtering the material, the control panel 46 controls the cylinder 414 to push the lifting plate 413 up. After the lifting plate 413 rises, the servo motor 42 and the push rod 415 push the filter disc 31 up, so that the sealing seat 217 at the bottom of the filter press 211 is sealed and connected with the filter press disc, and the filter cavity 312 is located at the bottom of the filter press 211. Then the control panel 46 controls the solenoid valve 216 in the first-stage filter press to open, so that the feed port 215 in the first-stage filter press is opened, so that the material enters the filter press 211 in the first-stage filter press from the feed port 215. After a certain amount of material is loaded into the filter press 211, the control panel 46 controls the solenoid valve 216 in the first-stage filter press to close, and then the control panel 46 controls the solenoid valve 216 in the first-stage filter press to close. The plate 46 controls the air pump 23 in the primary filtration to open, so that the air pump 23 pressurizes the filter press bin 211 through the air pressure pipe 24. After the filter press bin 211 is pressurized, the internal pressure pushes the piston 213 to move downward. When the piston 213 moves downward, it also pulls the spring 212 to stretch. The piston 213 moves downward to apply pressure to the material. After the material is pressurized, it passes through the filter screen 32 and enters the filter cavity 312, and enters the conical cylinder 33 through the filter cavity 312. Then, the control panel 46 controls the air pump 23 to open the pressure relief valve, so that the pressure in the filter press bin 211 is reduced, and the piston 213 returns to its original position under the action of the spring 212. The solenoid valve 216 of the primary feed port 215 is opened again to replenish the material, and the filtrate is continuously produced in this reciprocating manner.

[0046] Then the control panel 46 opens the electromagnetic valve 216 at the feed port 215 of the secondary filter press, so that the feed port 215 of the secondary filter press is opened, and the delivery pump 43 is started. The delivery pump 43 extracts the filtrate in the conical cylinder 33 during the primary filter press through the filtrate pipe 44, and delivers the filtrate from the feed port 215 of the secondary filter press into the secondary filter press bin 211 through the infusion pipe 45. After the filtrate is pumped into the secondary filter press bin 211, the control panel 46 turns on the air pump 23 corresponding to the secondary compression, and the air pump 23 pressurizes the secondary filter press bin 211. Since the aperture of the filter screen 32 of the secondary filter press is smaller, the filtrate is subjected to secondary filter press. The filtrate of the secondary filter press enters the secondary conical cylinder 33 and is collected through the collecting pipe 47.

[0047] When there is too much filter residue in the filter press 211, which affects the filtering efficiency, the control panel 46 turns off the air pump 23, the solenoid valve 216 and the delivery pump 43, and allows the piston 213 to return to its original position under the action of the spring 212. Then the control panel 46 controls the cylinder 414 to contract, causing the lifting plate 413 to descend, thereby driving the filter disc 31 to descend through the servo motor 42 and the push rod 415, so that the filter disc 31 is released from the sealing connection with the sealing seat 217. Then the control panel 46 controls the output end of the servo motor 42 to rotate, so that the servo motor 42 drives the filter disc 31 to rotate, and the filter chamber 312 is located below the water tank 22. At the same time, the nozzle 25 at the bottom of the water tank 22 sprays water to clean the filter screen 32. The filter residue above the filter screen 32 moves toward the collecting drawer 311 under the flushing of the water flow, thereby restoring the filtering effect of the filter screen 32.
