[0001] The invention relates to the technical field of paper mulberry paper production equipment, and in particular to a raw pulp residue water separation device for paper mulberry paper processing. Background Art

[0002] Paper mulberry paper is a kind of paper made from the bast fiber of paper mulberry trees. It has the characteristics of good toughness and long preservation. Paper mulberry paper is usually used for calligraphy and painting. When producing paper mulberry paper, it is usually necessary to use a crusher to crush the paper mulberry bark into fibers in advance, and then soak it in water to make it fully absorb water and soften into pulp, and then filter and dry it to form paper;

[0003] In the filtration of raw pulp, filter cartridges are conventionally used to separate the residue from water. Although the filter cartridge filtration method is simple, convenient and has obvious filtering effects, the material port of the filter cartridge is fixed, so that after the raw pulp is fed into the filter cartridge from the material port, the fiber residue can only accumulate on a local position on the surface of the built-in filter screen of the filter cartridge, forming a cone shape, which will seriously slow down the filtering effect of the raw pulp and reduce the use effect. Summary of the invention

[0004] In order to solve the above technical problems, a raw pulp residue-water separation equipment for mulberry paper processing is provided, which solves the problem that in the prior art, in raw pulp filtration, a filter cartridge is conventionally used to separate the residue and water, but the material port of the filter cartridge is fixed, so that after the raw pulp is fed into the filter cartridge from the material port, the fiber residue can only accumulate at a local position on the surface of the filter screen built into the filter cartridge, which seriously slows down the filtering effect of the raw pulp and reduces the use effect.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: a pulp residue water separation device for mulberry paper processing, comprising a filter cartridge with an open top, a filter cover arranged above the open top of the filter cartridge, a feed pipe fixedly connected to one side of the top of the filter cover, and a filter plate fixed inside the filter cartridge, the bottom of the filter cartridge wall is fixedly connected to a drain pipe, and also includes a grading flattening mechanism for preventing fiber residue from being locally accumulated on the filter plate;

[0006] The grading and flattening mechanism includes a driving rod vertically arranged above the middle of the filter plate, a telescopic scraping portion arranged on one side of the driving rod, a driving groove opened on the other side of the driving rod, and a linkage portion arranged in the driving groove for providing telescopic power for the telescopic scraping portion. A protective portion for increasing the service life of the linkage portion is also arranged on the inner side of the driving groove.

[0007] Preferably, the telescopic scraping portion is mainly composed of a plurality of groups of material spreading plates which are staggeredly distributed up and down in sequence, wherein there is a gap between the bottom material spreading plate and the filter plate, a connecting block is fixed between the top material spreading plate and the side surface of the driving rod, movable blocks are fixed to the sides of the remaining material spreading plates, and a movable rail groove which is compatible with the movable block is opened on the side wall of the driving rod.

[0008] Preferably, the linkage part includes two fixing plates symmetrically fixed between the inner walls on both sides of the driving groove, a transmission screw vertically rotatably arranged between the two fixing plates, and a push ring slidably sleeved on the rod body of the driving rod, the push ring is located at the bottom of the movable block at the bottom, and a nut seat fixedly connected to the inner wall of the push ring is threadedly sleeved on the rod body of the transmission screw.

[0009] Preferably, the linkage part also includes an incomplete internal toothed disk which is sleeved on the top of the driving rod body and fixedly connected to the inner wall of the top end of the filter cover, the inner side of the incomplete internal toothed disk is provided with a connecting plate which is vertically fixed to the driving rod body, a linkage column is vertically rotatably provided on the connecting plate, and a movable belt is connected to the linkage column and the transmission screw rod for transmission.

[0010] Preferably, a gear is fastened to the top end of the linkage column, and the gear is meshed with the inner tooth surface of the incomplete inner toothed disc.

[0011] Preferably, the protection part includes two pulleys which are symmetrically distributed up and down and rotate between the inner walls on both sides of the driving groove, and a transmission belt which is connected between the two pulleys, the two ends of the transmission belt are respectively fixed on the two sides of the push ring, and the two fixing plates are located between the two pulleys.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] (1) Through the arrangement of the telescopic scraping part and the linkage part, when the driving rod rotates, the linkage part acts on multiple groups of spreading plates to rise in sequence until they are merged into a strip plate. In this way, the telescopic scraping part can gradually expand the gap between it and the filter plate during the turnover process, so that when the amount of fiber residue accumulated is large, the fiber residue can be evenly distributed, avoiding the fixed structure and single size of the telescopic scraping part, which leads to a fixed distance between it and the filter plate, so that the fiber residue can only be scraped to a single thickness. Once the amount of fiber residue accumulated is large, a large amount of fiber residue will still move with the scraper after a week of circumferential scraping, and it cannot be evenly distributed.

[0016] (2) Through the setting of the protection part, during the upward movement of the push ring, the push ring can synchronously act on the transmission belt to operate, and then, under the premise of not affecting its activity, the transmission belt can be used to effectively hide the transmission screw in the protection linkage part. While the spreading plate is scraping the fiber residue, the fiber residue enters the inner side of the driving groove and adheres to the shaft of the transmission screw, affecting the transmission effect of the transmission screw on the nut seat.

[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0025] Reference Figure 1-5 As shown, a pulp-slag water separation device for paper mulberry processing comprises a filter cartridge 1 with an open top, a filter cover 4 arranged above the open top of the filter cartridge 1, a feed pipe 5 fixedly connected to one side of the top of the filter cover 4, and a filter plate 2 fixed to the inner side of the filter cartridge 1, and a drain pipe 3 fixedly connected to the bottom of the filter cartridge 1 wall;

[0026] When in use, the raw pulp to be processed is fed into the inner side of the filter cartridge 1 through the feeding pipe 5 in advance, so that when the raw pulp passes through the filter plate 2, the fiber residue is intercepted by the filter plate 2, which is convenient for subsequent processing, and the pulp water falls into the bottom of the inner side of the filter cartridge 1 through the filter holes and is discharged outwardly through the drain pipe 3, thereby achieving the effect of separating the raw pulp, residue and water.

[0027] However, from a practical point of view, the position of the feeding pipe 5 is fixed, so that after the raw pulp is fed into the filter cartridge 1 through the feeding pipe 5, the fiber residue can only be accumulated at a local position on the surface of the filter plate 2 to form a cone, which seriously slows down the filtering effect of the raw pulp and reduces the use effect;

[0028] For this purpose, refer to Figure 2 As shown, it is worth noting that it also includes a graded flattening mechanism for preventing the fiber residue from being locally accumulated on the filter plate 2;

[0029] The grading and leveling mechanism includes a driving rod 6 vertically arranged above the middle of the filter plate 2 and a telescopic scraping portion arranged on one side of the driving rod 6. A servo motor 20 is vertically installed on the top of the filter cover 4. The output shaft of the servo motor 20 rotates and penetrates into the filter cover 4 and is fixedly connected to the top of the driving rod 6.

[0030] After the raw pulp is fed into the filter plate 2 through the feeding pipe 5, the servo motor 20 is turned on, and the output shaft of the servo motor 20 acts on the driving rod 6 in the grading and leveling mechanism to continuously rotate, thereby causing the telescopic scraping part to rotate on the filter plate 2, scraping the accumulated fiber residue and spreading it evenly on the filter plate 2 to avoid conical accumulation and affect the filtration efficiency.

[0031] Further, refer to Figure 2-5 As shown, it is worth noting that the grading and leveling mechanism further includes a driving groove 12 provided on the other side of the driving rod 6 and a linkage part provided in the driving groove 12 for providing telescopic power to the telescopic scraping part;

[0032] The telescopic scraping part is mainly composed of a plurality of groups of spreading plates 7 which are staggered and distributed up and down in sequence, wherein there is a gap between the bottom spreading plate 7 and the filter plate 2, a connecting block 10 is fixed between the top spreading plate 7 and the side of the driving rod 6, and movable blocks 8 are fixed to the sides of the remaining spreading plates 7, and a movable rail groove 9 adapted to the movable block 8 is opened on the side wall of the driving rod 6;

[0033] Through the arrangement of the telescopic scraping part and the linkage part, during the rotation of the driving rod 6, the linkage part acts on multiple groups of spreading plates 7 to rise in sequence until they are merged into a strip plate, so that the telescopic scraping part can successively expand the gap between it and the filter plate 2 during the turnover process, so that when the amount of fiber residue accumulated is large, the fiber residue can be evenly distributed, avoiding the fixed structure and single size of the telescopic scraping part, resulting in a fixed distance between it and the filter plate 2, so that the fiber residue can only be scraped to a single thickness. Once the amount of fiber residue accumulated is large, a large amount of fiber residue will still move together with the scraper after one week of circumferential scraping, and it cannot be evenly distributed.

[0034] Further, refer to Figure 5 As shown, it is worth noting that the linkage part includes two fixing plates 13 symmetrically fixed between the inner walls of both sides of the driving groove 12, a transmission screw 14 vertically rotatably arranged between the two fixing plates 13, and a push ring 11 slidably sleeved on the rod body of the driving rod 6, the push ring 11 is located at the bottom of the lowest movable block 8, and a nut seat 15 fixedly connected to the inner wall of the push ring 11 is threadedly sleeved on the rod body of the transmission screw 14;

[0035] The linkage part also includes an incomplete inner toothed disc 19 which is sleeved on the top of the driving rod 6 and fixed to the inner wall of the top of the filter cover 4. A connecting piece 16 which is vertically fixed to the driving rod 6 is arranged on the inner side of the incomplete inner toothed disc 19. A linkage column 17 is vertically rotated on the connecting piece 16. A movable belt is connected between the linkage column 17 and the driving screw 14.

[0036] The top end of the linkage column 17 is tightly sleeved with a gear 18, which meshes with the inner tooth surface of the incomplete inner toothed disc 19;

[0037] When the driving rod 6 rotates one circle, the driving rod 6 is carried by the connecting piece 16 to rotate synchronously with the linkage column 17 and the gear 18 as a whole on the inner side of the incomplete internal gear disk 19, so that the gear 18 is meshed with the inner tooth surface of the incomplete internal gear disk 19, so that the linkage column 17 is forced to rotate once, and the transmission screw 14 is driven by the movable belt, so that the nut seat 15 carries the push ring 11 to slide up once under the threaded structure, and the push ring 11 pushes up the lower spreading plate 7 once, thereby expanding the distance between the spreading plate 7 and the filter plate 2 once.

[0038] Further, refer to Figure 5 As shown, it is worth noting that a protective portion for increasing the service life of the linkage portion is also provided on the inner side of the driving groove 12;

[0039] The protection part includes two pulleys 21 symmetrically distributed up and down and rotating between the inner walls of the driving groove 12 and a transmission belt 22 connected between the two pulleys 21. The two ends of the transmission belt 22 are respectively fixed on the two sides of the push ring 11. The two fixing plates 13 are located between the two pulleys 21.

[0040] Through the setting of the protection part, during the upward movement of the push ring 11, the push ring 11 can synchronously act on the transmission belt 22 to operate, and then without affecting its activity, the transmission belt 22 can be used to effectively hide the transmission screw 14 in the protection linkage part. While the spreading plate 7 is scraping the fiber residue, the fiber residue enters the inner side of the driving groove 12 and adheres to the rod body of the transmission screw 14, affecting the transmission effect of the transmission screw 14 on the nut seat 15.

[0041] Further, refer to Figure 1 As shown, it is worth noting that two connecting ring plates 23 are provided at the joint of the filter cover 4 and the filter cartridge 1, and the two connecting ring plates 23 are respectively fastened and sleeved on the outer walls of the filter cover 4 and the filter cartridge 1, and the two connecting ring plates 23 are detachably connected by bolts;

[0042] Through the arrangement of the two connecting ring plates 23, after the slurry is filtered, the fixing effect between the filter cover 4 and the filter cartridge 1 can be released by manually loosening the bolts between the two connecting ring plates 23, and the filter cover 4 can be removed from the open end of the filter cartridge 1, so as to facilitate the disposal of the filtered fiber residue on the filter plate 2.
