Description

Technical Field

[0001] This utility model relates to the field of paper processing technology, specifically to a clean papermaking pulping machine. Background Technology

[0002] Papermaking was an important practical innovation for the working people of ancient China, and it came in two forms: machine-made and handmade. Machine-made papermaking was a continuous process on a papermaking machine. Pulp suitable for paper quality was diluted with water to a certain concentration, and then initially dewatered on the wire section of the papermaking machine to form a wet sheet. It was then pressed to remove more water and finally dried to become paper. In a Chinese patent with publication number CN219653378U entitled "A Pulping Machine for Clean Papermaking", a mixing motor, a mixing shaft and a mixing blade structure can be used to mix waste paper scraps and water inside the mixing tank. A centrifugal motor and a slurry deflection assembly structure can also be used to slurry and filter the formed pulp. With the addition of a filter screen plate in the middle of the pulp filter tank, the pulp liquor discharged from the mixing tank can be filtered twice, and clumps and large-diameter pulp can be filtered out. This ensures the fineness of the pulp liquor discharged from the first discharge pipe and the quality of clean papermaking. However, this device still has shortcomings. The above-mentioned equipment uses a pulp screen and a centrifugal motor to achieve the shoveling of pulp liquor. However, when the pulp is shoveling, the centrifugal force causes the pulp to adhere to the pulp screen. This not only reduces the filtration area and prolongs the separation time, but also causes some fibers to become embedded in the filter holes due to prolonged adhesion (clogging the filter holes). In order to solve the above problems, the inventors have proposed a clean papermaking pulping machine. Utility Model Content

[0003] In order to solve the problem that the pulp adheres to the screen mesh due to centrifugal force when the pulp is spun, the purpose of this utility model is to provide a clean pulping machine for papermaking.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a clean papermaking pulping machine, including a load-bearing vertical plate, a main box body fixedly connected to the front end of the load-bearing vertical plate, a mixing tank fixedly connected to the center of the top of the main box body, a cylindrical mounting frame rotatably connected to the center of the bottom of the mixing tank, a pulp screen fixedly connected to the inner wall of the cylindrical mounting frame, a detachable mounting top cover above the mixing tank, a stirring paddle rotatably connected to the center of the bottom of the mounting top cover, a top cover fixedly connected to the top of the mounting top cover, a sliding shaft fixedly connected to the center of the top of the top cover, a top plate slidably connected to the outer ring of the sliding shaft, a spring fixedly connected to the center of the bottom of the top plate and fitted onto the outer ring of the sliding shaft, a plurality of pulling shafts slidably inserted in a ring near the center inside the mounting top cover, and the top of the pulling shafts fixedly connected to the top plate, a flexible scraper fixedly connected to the outer ring of the pulling shafts near the bottom, and the flexible scraper contacting the pulp screen.

[0005] Preferably, a waterproof motor is installed at the center of the top of the main body, and the output end of the waterproof motor passes through the mixing tank and is fixedly connected to the cylindrical mounting frame. A filter screen is installed at the center of the main body.

[0006] Preferably, a water outlet pipe is fixedly connected to the side end of the main tank near the bottom center, and a transfer pipe is symmetrically fixedly connected to the outer ring of the mixing tank near the bottom center, with the other end of the transfer pipe penetrating the main tank. A connecting shaft is rotatably connected to the top center of the mounting cover, with the bottom end of the connecting shaft penetrating the mounting cover and fixedly connected to the mixing paddle. A first gear is fixedly connected to the outer ring of the connecting shaft near the top.

[0007] Preferably, a micro motor is provided at the top of the mounting cover near the center, and a second gear is fixedly connected to the output end of the micro motor, and the second gear meshes with the first gear.

[0008] Preferably, a bevel gear one is rotatably connected to the top of the top cover near the center, and the bottom end of the bevel gear one passes through the top cover and is fixedly connected to a second gear. A mounting block is fixedly connected to the top of the top cover near the bevel gear. A bevel gear two is rotatably connected to the side end of the mounting block, and the bevel gear two meshes with the bevel gear one. An eccentric wheel is rotatably connected to the other side end of the mounting block, and the side end of the bevel gear two passes through the mounting block and is fixedly connected to the eccentric wheel.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, a bevel gear drives an eccentric wheel to rotate, which, in conjunction with a spring, causes the top plate to move the pull shaft and flexible scraper up and down. During the rotation of the cylindrical mounting frame, the flexible scraper continuously moves the pulp on the screen, effectively preventing the pulp from adhering to the screen for a long time and clogging the filter holes. This ensures the smooth progress of the screening process, reduces the frequency of equipment downtime for cleaning, and improves production continuity. Attached Figure Description

[0032] Working principle: When using this equipment, first remove the top cover 4, then put the shredded waste paper into the cylindrical mounting frame 33 inside the mixing tank 3. When it is necessary to mix the waste paper into pulp, inject a certain amount of water into the mixing tank 3, and then operate the micro motor 42 and the waterproof motor 32 (micro motor 42 rotates forward and waterproof motor 32 rotates in reverse). After the waterproof motor 32 works, it can make the fixedly connected cylindrical mounting frame 33 rotate. After the micro motor 42 works, under the action of the first gear 43 and the second gear 44, it will drive the mixing paddle 35 to rotate in the opposite direction, thereby realizing the mixing treatment of waste paper and water. When the shredded paper and water are fully mixed, they can form pulp raw material for cleaning papermaking. When the diameter of the pulp is small enough, it can pass through the pulp screen 34 and enter the mixing tank 3. Then, through the transfer pipe 31, the wastewater can be transported to the main tank 2 and taken out through the outlet pipe 22. When the micro motor 42 is working, it can also drive the first bevel gear 45 to rotate, and cooperate with the second bevel gear 47 to rotate, thereby driving the fixedly connected eccentric wheel 48 to rotate. Then, in conjunction with the spring 52, the top plate 51 can drive the pull shaft 53 and the flexible scraper 54 to move up and down. When the cylindrical mounting frame 33 rotates, it can move the pulp thrown on the screen 34, avoiding the situation where the pulp adheres to the screen 34 for a long time and causes the filter holes to be blocked.
