Description

Technical Field

[0001] The utility model relates to the technical field of pulpers, in particular to a rotary drum pulper. Background Art

[0002] The rotary drum pulper is a new and advanced waste paper pulping equipment, which is a replacement product of the traditional hydraulic pulper. The main structure of this equipment is a specially designed rotary drum device with a slight inclination - the front section is the pulping area, and the rear section is the screening area. During the working process, the rotary drum rotates at a certain speed. Waste paper raw materials, water and appropriate chemicals are continuously added from one end of the rotary drum and mixed together. The lifters inside the rotary drum continuously scoop up and drop the wet waste paper, and slowly move from the pulping area towards the screening area. The impact and friction generated by this action can "gently" loosen the waste paper fibers and better maintain the strength of the fibers; at the same time, the friction, rolling and collision between the fibers can efficiently peel off the ink particles, film pieces and hot melt adhesives from the fiber surface.

[0003] Due to the large volume of the existing rotary drum pulpers, their feeding hoppers are generally set at a high position, resulting in the need for manual carrying and climbing to a high position during feeding. Further, there will be certain potential safety hazards during the feeding process, with high risk. Content of the Utility Model

[0027] In this embodiment, the hinged plate 46 is arranged to drive the standing plate 43 to move.

[0028] Specifically, L-shaped plates 47 are fixedly installed on both side surfaces of the bottom plate 1. A cylinder 48 is fixedly installed on the vertical surface of the L-shaped plate 47. The output end of the cylinder 48 is fixedly connected with the movable plate 45. The cylinder 48 is arranged to drive the movable plate 45 to move inside the long groove 44.

[0029] In this embodiment, a sealing device 5 is arranged on the side of the feed hopper 3. The sealing device 5 includes two fixing plates 51 which are fixedly installed on the side of the feed hopper 3. A threaded rod 52 is rotatably connected between the two fixing plates 51. A motor 53 is fixedly installed on the surface of one of the fixing plates 51, and the output end of the motor 53 is fixedly connected with the threaded rod 52. When the water and the cardboard all enter the inside of the pulping machine body 2, the motor 53 is started at this time. The motor 53 drives the threaded rod 52 to rotate when it starts. The threaded rod 52 rotates to drive the displacement plate 55 to move inside the strip-shaped groove 54. The displacement plate 55 moving inside the strip-shaped groove 54 drives the connecting rod 56 to move. The connecting rod 56 moving drives the sealing plate 57 to move. The sealing plate 57 moves to slide into the inside of the feed hopper 3.

[0033] In this embodiment, the provision of the sealing plate 57 has the effect of sealing the feed hopper 3.

[0034] Working principle: By providing the lifting device 4, when the device needs to be used, first place the cardboard and water on the standing plate 43, and then let the worker stand on the standing plate 43. After standing, start the two cylinders 48 simultaneously. The start of the cylinders 48 drives the two movable plates 45 to move towards each other inside the long groove 44. The movement of the two movable plates 45 towards each other inside the long groove 44 drives the articulated plate 46 to move. The movement of the articulated plate 46 pushes the standing plate 43 to move upward. The upward movement of the standing plate 43 drives the sliding plate 42 to move upward on the surface of the sliding rod 41. At the same time, the upward movement of the standing plate 43 also drives the cardboard, water, and the worker to move upward. When the standing plate 43 moves upward to a suitable position, turn off the cylinders 48, and then the worker conveys the water and cardboard into the interior of the pulper body 2 through the feed hopper 3. Through the cooperation of the above structures, during feeding, there is no need for the worker to climb up for feeding, improving the safety of the device during the feeding process. When all the water and cardboard enter the interior of the pulper body 2, start the motor 53 at this time. The start of the motor 53 drives the threaded rod 52 to rotate. The rotation of the threaded rod 52 drives the displacement plate 55 to move inside the strip-shaped groove 54. The movement of the displacement plate 55 inside the strip-shaped groove 54 drives the connecting rod 56 to move. The movement of the connecting rod 56 drives the sealing plate 57 to move. The movement of the sealing plate 57 causes it to slide into the interior of the feed hopper 3. When the sealing plate 57 completes the sealing operation of the feed hopper 3, turn off the motor 53, and then start the pulper body 2 to complete the corresponding pulping operation. Through the cooperation of the above structures, the sealing plate 57 can seal the feed hopper 3, preventing the materials inside the pulper body 2 from flowing out of the feed hopper 3 when the pulper body 2 is flipped, which has an adverse impact on pulping.
