Description

Technical Field

[0001] The utility model relates to the field of collection and recycling equipment, and particularly relates to equipment for collecting and recycling paper-making residues and pulp. Background Art

[0002] A large amount of recyclable paper-making fibers are contained in the residues and pulp of paper-making. Directly discarding them will cause waste. Therefore, it is necessary to recycle these residues and pulp. In the prior art, the Chinese utility model patent with the publication number: CN212865426U discloses a device for collecting and recycling paper-making residues and pulp. In this utility model, a motor drives a stirring fan blade and a cutting fan blade to rotate. Under the combined action of the stirring fan blade and the cutting fan blade, the pulp is centrifuged in a centrifugal tank and a separation tank, and at the same time, larger fibers are cut and separated, so that pulp fibers of different sizes are stratified.

[0003] However, the residues are not easy to separate. In this utility model, the stirring fan blade and the cutting fan blade rotate in the same direction. The stirring fan blade stirs the fluid to rotate in a vortex, and rotates in the same direction and at the same speed as the cutting fan blade, resulting in poor crushing effect and long crushing time for the residues and pulp. Therefore, improvement is needed. Summary of the Utility Model

The crushing component 4 further includes an inlet 402, which is opened on the inlet groove 401 and is located above the upper end of the guiding plate 403. The first crushing roller 404 is located above the lower end of the guiding plate 403. The second crushing roller 406 is located on the side of the first crushing roller 404 and is located outside the guiding plate 403. The crushing component 4 further includes a bearing 408, a first gear 409, a second gear 410 and a first stepping motor 411. The first crushing roller 404 and the second crushing roller 406 are movably installed in the inlet groove 401 through the bearing 408. The first gear 409 and the second gear 410 are respectively fixedly connected to the first crushing roller 404 and the second crushing roller 406. The first gear 409 and the second gear 410 are movably installed. The first stepping motor 411 is fixedly connected to the box cover 1, and the output shaft of the first stepping motor 411 is fixedly connected to the first crushing roller 404. The first rotating rod 412 is also movably installed in the collection box 2 through the bearing 408. The residues and pulp are mixed with a certain amount of pulp water and flow downward along the inclined guiding plate 403. The first stepping motor 411 rotates the first crushing roller 404, so that the first crushing rod 405 is on the guiding plate 403 to crush the residues and pulp and push the residues and pulp downward, so that the residues and pulp are initially crushed. The residues and pulp at the lower position of the guiding plate 403 are pushed downward by the first crushing rod 405, making it not easy for the feeding to be blocked.

[0023] As Figure 1 , Figure 3 and Figure 4As shown, the first rotating rod 412 is movably installed in the collection box 2. The spiral stirring blade 413 is fixedly connected to the first rotating rod 412 and is located inside the collection box 2. The connection box 415 is fixedly connected to the upper end of the first rotating rod 412. The movable rod 419 is movably installed on both sides of the connection box 415. The scraper 420 is fixedly connected to the outer end of the movable rod 419. The crushing assembly 4 further includes a second stepping motor 414. The second stepping motor 414 is fixedly connected to the bottom surface of the collection box 2, and the output shaft of the second stepping motor 414 is fixedly connected to the first rotating rod 412. The crushing assembly 4 further includes a storage groove 416, a spring 417, and a movable block 418. The storage groove 416 is opened on both sides of the connection box 415. The movable block 418 and the spring 417 are movably installed in the storage groove 416. The movable rod 419 is fixedly connected to the movable block 418, and the movable block 418 is located on the side of the spring 417. The box cover 1 is fixedly connected above the collection box 2. The bottom surface of the collection box 2 is fixedly connected with a support foot 3, and a discharge pipe is fixedly connected to the bottom surface of the collection box 2. The second stepping motor 414 rotates the first rotating rod 412, so that the spiral stirring blade 413 on the first rotating rod 412 rotates. The spiral stirring blade 413 stirs the fluid to form a vortex rotation, further crushing the residue and pulp that have undergone preliminary crushing, making the crushing effect of the residue and debris better. And the spring 417 pushes the scraper 420 to move outward, making the scraper 420 closely fit the inner wall of the collection box 2, making the effect of the scraper 420 removing the residue on the inner wall of the collection box 2 better.

[0024] It should be noted that the present utility model is a device for collecting and recycling paper-making residues and pulp. After the residues and pulp in paper-making are collected, they are put into the inlet 402 of the inlet tank 401. The residues and pulp are mixed with a certain amount of pulp water and flow downward through the inclined guiding plate 403. The first stepping motor 411 rotates the first crushing roller 404, so that the first crushing rod 405 is above the lower end of the guiding plate 403 to crush the residues and pulp and push the residues and pulp downward, so as to prevent the feed from being blocked. The first gear 409 on the first crushing roller 404 rotates synchronously and rotates the second crushing roller 406 through the second gear 410, so that the rotation direction of the second crushing roller 406 is opposite to that of the first crushing roller 404. The second crushing rod 407 is located in the middle of the first crushing rod 405. After rotating together with the second crushing roller 406, the second crushing rod 407 scrapes the residues and pulp on the first crushing roller 404. The second crushing roller 406 is located outside the guiding plate 403, so that the debris on it is easy to fall downward under the action of gravity. The second stepping motor 414 is started, so that the first rotating rod 412 and the spiral stirring blades 413 rotate synchronously, so that the fluid in the collection box 2 is easy to stir. Through the vortex flow of the fluid, the residues and pulp are torn and mixed, so that the mixing effect of the residues and pulp is better. The connection box 415 rotates synchronously with the first rotating rod 412. The receiving groove 416 of the connection box 415 houses the movable block 418 and the movable rod 419. The compressed spring 417 pushes the movable block 418 and the movable rod 419 outward, so that the scraping plate 420 at the outer end of the movable rod 419 moves outward synchronously, so that the scraping plate 420 is in closer contact with the inner wall of the collection box 2, and the effect of removing the residues remaining on the inner wall of the collection box 2 is better.
