[0001] The utility model relates to the technical field of papermaking, in particular to a pulp filtering device. Background Art

[0002] Pulp is a fibrous material made from plant fibers through different processing methods. It can be divided into mechanical pulp, chemical pulp and chemical mechanical pulp. These pulps are widely used in the manufacture of paper and paperboard, and can also be used as raw materials for the manufacture of cellulose derivatives such as cellulose esters and cellulose ethers. They are also used in the fields of artificial fibers, plastics, coatings, films, gunpowder, etc.

[0003] The pulp filter is a device used to process pulp, and its purpose is to remove impurities and pollutants in the pulp to improve the quality and performance of paper. Traditional pulp filter devices usually use mechanical filtration, chemical precipitation and flotation methods. When filtering pulp, the filter screen is fixed and the filtration effect is achieved by the gravity of the pulp liquid. This has a very poor filtration effect. At the same time, long-term filtration causes a large amount of impurities to accumulate on the filter screen, which requires the staff to manually disassemble the filter screen and clean the pulp filter device. Utility Model Content

[0006] As a preferred technical solution of the utility model, the lifting mechanism includes a sleeve, the lower parts of the two electric sliders are fixedly connected to the sleeve, the middle part of the sleeve is slidably connected to a hexagonal rod, the middle part of the hexagonal rod is provided with a disc, the hexagonal rod passes through the filter frame, and the disc on the hexagonal rod is in contact with the bottom of the filter.

[0007] As a preferred technical solution of the utility model, the lifting mechanism also includes an overrunning clutch, the two sleeves are fixedly connected to the overrunning clutch, the two overrunning clutches are fixedly connected to the column gears, the two sides of the inner wall of the support shell are fixedly connected to the gear rod, the gear rod is directly below the electric slide rail, and the gear rod is meshed with the column gear.

[0008] As a preferred technical solution of the utility model, the lifting mechanism also includes a sliding rod, the upper part of the filter frame is slidably connected to the sliding rod, the ends of the two sliding rods close to each other are fixedly connected to half nuts, the tops of the two hexagonal rods are fixedly connected to screw rods, the screw rods and the half nuts are threadedly connected, and a pressure spring is connected between the filter frame and the sliding rod.

[0009] As a preferred technical solution of the utility model, it also includes a scraper rod, which is slidably connected to the upper part of the support shell, and two hoppers are fixedly connected to the inner side of the upper part of the support shell, and the hoppers are located directly above the electric slide rail.

[0010] Beneficial effects: 1. When filtering pulp liquid, the electric slider moves back and forth along the electric slide rail, the electric slider causes the filter frame to shake, and then the filter screen in the filter frame filters out larger impurities in the pulp. In this way, the filter frame and the filter screen are driven to shake by the electric slider, thereby enhancing the filtering effect of the device on the pulp.

[0011] 2. During the back and forth movement of the filter frame, the screw will rotate and rise, thereby driving the filter to rise. When the filter rises to the same level as the top of the filter frame, the staff will remove the impurities on the filter and then pull the sliding rod to both sides. The sliding rod drives the half nut away from the screw, and the screw and the half nut are separated. The filter, hexagonal rod and screw fall back to their original positions under the action of gravity. In this way, the filter will move up and down reciprocatingly, so that when the filter rises to the highest point, it will be convenient for the staff to quickly clean the filter.

DETAILED DESCRIPTION

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0019] Embodiment 1: A pulp filtering device, such as Figure 1-Figure 5 As shown, it includes a supporting shell 1, both sides of the inside of the supporting shell 1 are connected with electric slide rails 2 by bolts, and the two electric slide rails 2 are slidably connected with electric sliders 3, and a filter frame 4 is connected between the two electric sliders 3 by bolts. A filter screen 41 is slidably connected in the filter frame 4, and a lifting mechanism for lifting the filter frame 4 is provided in the supporting shell 1.

[0020] The lifting mechanism includes a sleeve 5, and the lower parts of the two electric sliders 3 are fixedly connected to the sleeve 5. The middle part of the sleeve 5 is slidably connected to a hexagonal rod 6, and a disc is provided in the middle part of the hexagonal rod 6. The hexagonal rod 6 passes through the filter frame 4. The movement of the hexagonal rod 6 will drive the filter frame 4 to move, and the disc on the hexagonal rod 6 contacts the bottom of the filter screen 41.

[0021] The lifting mechanism also includes an overrunning clutch 7, and the two sleeves 5 are fixedly connected to the overrunning clutch 7. The two overrunning clutches 7 are fixedly connected to the column gear 8. Gear rods 9 are welded on both sides of the inner wall of the support shell 1. The gear rods 9 are directly below the electric slide rail 2, and the gear rods 9 are meshed with the column gears 8.

[0022] The lifting mechanism also includes a sliding rod 10, the sliding rod 10 is slidably connected to the upper part of the filter frame 4, half nuts 11 are welded to the ends of the two sliding rods 10 close to each other, and screws 111 are fixedly connected to the tops of the two hexagonal rods 6. The screws 111 and the half nuts 11 are threadedly connected, and a pressure spring 12 is connected between the filter frame 4 and the sliding rod 10, and the pressure spring 12 is used to drive the filter frame 4 to reset.

[0023] At first, the staff pours the pulp liquid to be filtered into the filter frame 4, and then the staff starts the electric slider 3, and the electric slider 3 moves back and forth along the electric slide rail 2. The electric slider 3 shakes the filter frame 4, and then the filter screen 41 in the filter frame 4 filters out larger impurities in the pulp. In this way, the filter frame 4 and the filter screen 41 are driven to shake by the electric slider 3, thereby enhancing the filtering effect of the device on the pulp.

[0024] In the process of the filter frame 4 moving back and forth, the column gear 8 and the gear rod 9 will mesh, and the column gear 8 will rotate forward and reverse. Due to the unidirectional rotation characteristic of the overrunning clutch 7, when the column gear 8 rotates forward, the column gear 8 will drive the sleeve 5 to rotate, and the rotation of the sleeve 5 drives the hexagonal rod 6 to rotate, and the hexagonal rod 6 drives the screw 111 to rotate. Since the half nut 11 is fixed, the screw 111 will rise when it rotates. When the screw 111 rises, the screw 111 drives the hexagonal rod 6 to rise. The disc provided on the hexagonal rod 6 will squeeze the filter screen 41, so that the hexagonal rod 6 will The filter screen 41 is driven to rise. When the filter screen 41 rises to the same level as the top of the filter frame 4, the staff removes the impurities on the filter screen 41 and then pulls the two sliding rods 10 away from each other. The sliding rod 10 drives the half nut 11 away from the screw rod 111. The screw rod 111 and the half nut 11 are disengaged, and the filter screen 41, the hexagonal rod 6 and the screw 111 fall back to their original positions under the action of gravity. In this way, the filter screen 41 will move up and down reciprocatingly, so that when the filter screen 41 rises to the highest point, it is convenient for the staff to quickly clean the filter screen 41.
