ring 14 drives the sliding ring 10 to rotate through the second switching tooth 15 and the first switching tooth 11, the sliding ring 10 slides in the spiral groove of the first guiding groove 12, the sliding ring 10 moves upwards under the action of the first guiding groove 12, the filter screen 7 positioned in the filter cartridge 3 is switched to the outer side of the filter cartridge 3, after the filter screen 7 is blocked, the filter screen 7 inside and outside the filter cartridge 3 is switched timely, the filtering effect of the filter screen 7 is ensured, the filter screen 7 is prevented from being blocked, the filtering rate of the filter screen 7 is slowed down, the whole production process is dragged slowly, the blocking plate 20 slides in the spiral groove of the second guiding groove 22, the sliding ring 10 moves to the top part of the first guiding groove 12 again after the filter screen 7 moves to the outer side of the filter cartridge 3, when the baffle plate 20 moves to the top of the second guide groove 22, the baffle plate 20 moves under the action of a gas spring, the second oil passing port 21 is communicated with the first oil passing port 17 again, when the baffle ring 19 moves out of the filter cylinder 3, the limiting block 24 moves to the outer side of the filter cylinder 3 together, the limiting block 24 moves to the outer side of the baffle ring 19 under the action of the spring, the limiting block 24 removes the limiting of the edge of the turnover rod 23 and the edge of the filter screen 7, the turnover rod 23 turns downwards under the action of gravity, the residue on the surface of the filter screen 7 flows downwards along the surface of the filter screen 7, the filtered residue can be cleaned out of the surface of the filter screen 7 in time, the filtering effect of the filter screen 7 after the subsequent switching is ensured, the phenomenon that the residue filtered on the surface of the filter screen 7 cannot be cleaned in time is avoided, the filter screen 7 is always in a blocking state, the filter screen 7 still cannot be filtered well after the switching again, when the filter screen 7 is switched again, the filter screen 7 and the blocking plate 20 which are positioned on the outer side of the filter cartridge 3 move downwards together in the rotating direction, when the limiting block 24 moves into the filter cartridge 3, the inner wall of the filter cartridge 3 acts on the limiting block 24 to move towards the position close to the blocking ring 19, the bottom of the limiting block 24 moves into the blocking ring 19, then when the turnover rod 23 and the filter screen 7 move upwards, the bottom of the limiting block 24 contracts and passes over the limiting block 24 due to the fact that the turnover rod 23 and the filter screen 7 act on the limiting block 24, and the limiting block 24 limits the turnover rod 23 and the filter screen 7 again.
In the filtering process, the residue on the surface of the filter screen 7 is blocked at the mesh position and cannot flow out of the filter screen 7, as a further scheme of the invention, the surface of the filter cartridge 3 is fixedly connected with a cleaning plate 25, the cleaning plate 25 is positioned below the filter screen 7, the surface of the cleaning plate 25 is fixedly connected with a brush 26, the overturning rod 23 can overturn to the surface of the cleaning plate 25, one side of the surface of the filter cartridge 3 corresponding to the rotation direction of the filter screen 7 is elastically and slidably connected with an arc-shaped block 27, and the arc-shaped block 27 can guide the filter screen 7 and the overturning rod 23 to move upwards; in the filtering process, when the turnover rod 23 and the filter screen 7 turn downwards, the end part of the turnover rod 23 can turn over to the position of the cleaning plate 25, the brush 26 can dredge the residual meal in the meshes of the filter screen 7 through the meshes of the filter screen 7, so that the dredging of the filter screen 7 is guaranteed, the meshes of the filter screen 7 are prevented from being blocked, the filter screen 7 cannot play a filtering role after subsequent switching, the cleaning plate 25 can play a supporting role on the turnover rod 23 and the filter screen 7, the turnover rod 23 and the filter screen 7 cannot move to the inside of the blocking ring 19 again, and the arc-shaped block 27 can guide the turnover rod 23 and the filter screen 7 upwards when the filter screen 7 and the turnover rod 23 move, so that the turnover rod 23 and the filter screen 7 can smoothly move to the inside of the blocking ring 19.
In the filtering process, the residue on the surface of the filter screen 7 cannot flow out of the surface of the filter screen 7 completely, as a further scheme of the invention, a telescopic pushing plate 28 is connected between the plurality of turning rods 23 in a sliding way, a telescopic guide rod 29 is fixedly connected between the pushing plates 28, the guide rod 29 penetrates through the turning rods 23 and the filter screen 7 and then extends to the surface of the cleaning plate 25, a guide plate 30 is fixedly connected to the surface of the cleaning plate 25, and the guide rod 29 can gradually move outwards under the action of the guide plate 30; in the filtering process, when the filter screen 7 moves out of the filter cylinder 3, the guide rod 29 moves along with the filter screen 7, the guide rod 29 moves to the surface of the cleaning plate 25, then when the sliding ring 10 rotates again, the sliding ring 10 drives the turning rod 23 to rotate together with the guide rod 29, the guide rod 29 moves outwards under the action of the guide plate 30, the guide rod 29 drives the pushing plate 28 to move outwards, the pushing plate 28 pushes residues filtered on the surface of the filter screen 7 away from the filter screen 7, the residues on the surface of the filter screen 7 can be cleaned completely, the filtering effect after the filter screen 7 is switched is guaranteed, the residues on the surface of the filter screen 7 are prevented from being cleaned completely, the filter screen 7 after switching can be blocked again in a short time, the filtering effect is poor, and then after the guide rod 29 is separated from the guide plate 30, the pushing plate 28 can be restored to the original position.
In the filtering process, cleaned residue flows outwards along the edge of the filter screen 7, so that cleaning and collection are inconvenient, and as a further scheme of the invention, the surface of the filter cartridge 3 is fixedly connected with a receiving cylinder 31, the receiving cylinder 31 is positioned below the cleaning plate 25, and the bottom of the receiving cylinder 31 is fixedly connected with a trash discharging pipe 32; in the filtering process, the cleaned residue can directly flow into the receiving barrel 31, so that the filtered residue can be collected by workers conveniently and subjected to secondary squeezing treatment, and the problem that the cleaned residue is inconvenient to collect and affects subsequent treatment is avoided.
