[0015] A method for using a cartridge-type multilayer filter press comprises the following steps: S1: The third cylinder drives the sliding seat to move inside the main frame and the filter press frame, so that the two barrels move inside one main frame and the filter press frame respectively; S2: The filter plate is placed at the lower end of the mobile trolley, the second cylinder drives the connecting block to move, the connecting block drives the second clamping arm to rotate, the second clamping arm drives the first clamping arm to rotate through the connecting rod, so that the two clamping blocks move in opposite directions, so that the clamping blocks clamp the filter cloth, the first cylinder drives the mobile trolley and the filter cloth to move, so that the filter cloth moves to the top of the barrel, and the filter cloth is released, so that the filter cloth falls into the barrel; S3: The material falls into the inside of the material distribution box through the feed pipe. In the auxiliary material discharging component, the sludge can pass through the material distribution plate and evenly fall into the inside of the barrel, above the filter cloth, to lay the material, and gradually lower the height of the scissor frame; S4: After the material is laid, the third cylinder drives the sliding seat to move, so that the barrel filled with material moves to the inside of the filter press frame, and the hydraulic press drives the upper pressing plate to move downward to squeeze the material. At the same time, the barrel located inside the main frame on one side is laid; S5: After pressure filtration, the sliding seat moves, causing the barrel after pressure filtration to move to the inner part of the main frame on the other side. The fourth cylinder drives the barrel to move upward, causing the filter cloth and the material cake to leak out. Under the action of the scissor lift and the guiding roller, they enter the inside of the flipping cage.

S6: The discharging motor drives one of the rotating crossbeams to rotate through the driving sprocket and the driving chain. The two rotating crossbeams rotate simultaneously under the action of the connecting gears. Under the action of the ribs on the surface of the rotating crossbeam, the filter cloth rotates and bounces, realizing the separation of the mud cake, and discharging through the gaps on the surface of the flipping cage. The fifth cylinder drives the moving pressing frame to move, which can ensure that when dewatering, the space between the filter cloths is not too small, preventing the filter cloth from tipping over and affecting the use. Moreover, the filter cloths after dewatering can be stacked together, facilitating the collection of the filter cloths.

[0016] The present invention has at least the following beneficial effects: 1. In the present invention, the material falls on the cloth plate of the cloth box through the feed pipe. The material can evenly fall on the filter cloth inside the barrel through the cloth plate, enabling uniform paving on the filter cloth during the pressure filtration process, and making the water content of the silt at different positions on the filter cloth uniform. The cloth motor drives the driving gear ring to rotate through the rotating gear. The driving gear ring drives the rotating rod to rotate through the meshing gear. The rotating rod drives the cam to rotate. As the cam rotates, the top ring can move up and down repeatedly under the action of the return spring. The top ring drives the top rod to move up and down, facilitating the knocking of the cloth plate, enhancing the cloth feeding speed. The fixed motor drives the rotating sleeve to rotate through the first driving gear and the second driving gear. The rotating sleeve drives the stirring bar to rotate. The stirring bar rotates on the surface of the cloth plate, which can stir the material and enhance the cloth feeding effect. 2. In the present invention, the filter cloth is placed under the moving trolley. The second cylinder drives the second clamping arm to rotate through the connecting block. The second clamping arm drives the first clamping arm to rotate through the connecting rod, causing the clamping blocks at the lower ends of the first clamping arm and the second clamping arm to move in opposite directions, facilitating the clamping of the filter cloth. The first cylinder drives the moving trolley to move, causing the filter cloth to move to the upper end of the barrel. The second cylinder drives the second clamping arm to rotate through the connecting block. Under the action of the connecting rod, the first clamping arm and the second clamping arm open, causing the filter cloth to fall into the barrel, facilitating the feeding of the filter cloth. 3. In the present invention, after pressure filtration, the sliding seat moves, causing the barrel after pressure filtration to move to the interior of the main frame on the other side. The fourth cylinder drives the barrel to move upward, causing the filter cloth and the material cake to leak out. Under the action of the scissor lift and the guide rollers, they enter the interior of the turning cage. The turning cylinder drives the turning frame and the turning cage to rotate, making the turning cage, the material cake, and the filter cloth in a vertical state. The feeding motor drives one of the rotating crossbeams to rotate through the driving sprockets and the driving chain. The two rotating crossbeams rotate simultaneously under the action of the connecting gears. Under the action of the ribs on the surface of the rotating crossbeams, the filter cloth rotates and bounces, realizing the separation of the mud cake, and discharging it through the gaps on the surface of the turning cage. The fifth cylinder drives the moving pressing frame to move, which can ensure that when dewatering, the space between the filter cloths is prevented from being too small, causing the filter cloth to tilt and affecting the use. Moreover, the filter cloths after dewatering can be stacked together, facilitating the collection of the filter cloths. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the material is laid on one side of the barrel (520) located inside the main frame (200); S5: After filtration, the sliding seat (510) moves, so that the material barrel (520) moves inside the main frame (200) on the other side after filtration, and the fourth cylinder (521) drives the material barrel (520) to move upward, so that the filter cloth and the material cake leak out, and under the action of the scissor frame (800) and the material guide roller (740), they enter the interior of the flip cage (710), and the flip cylinder (610) drives the flip frame (620) and the flip cage (710) to rotate, so that the flip cage (710), the material cake and the filter cloth are in a vertical state; S6: The unloading motor (711) drives one of the rotating beams (730) to rotate through the transmission sprocket and the transmission chain. The two rotating beams (730) rotate simultaneously under the action of the connecting gear (732). Under the action of the ribs (731) on the surface of the rotating beam (730), the filter cloth rotates and jumps, so that the mud cake is released and discharged through the gap on the surface of the flip cage (710). The fifth cylinder (720) drives the movable pressing frame (721) to move, so that when removing mud, the space between the filter cloths is small, which causes the filter cloths to fall over and affect the use. Moreover, the filter cloths after mud removal can be stacked together, so that the filter cloths are convenient to collect.
