Description

Technical Field

[0001] The invention relates to the technical field of papermaking machinery, and in particular to pulp processing equipment. Background Art

[0002] Waste newsprint, waste account paper, waste book and magazine paper and various office waste papers can be recycled. The recycled pulp and chemical pulp need to be washed and concentrated before and after bleaching. The existing pulp processing equipment has the advantages of high washing efficiency, large processing capacity and low power consumption for waste paper pulp and various waste paper deinking pulp, small footprint, simple operation and convenient installation. Various pulps can meet the pulp cleanliness requirements by passing through only one such equipment without the need to add subsequent pulp washing equipment.

[0003] However, during the long-term use of the prior art, it was found that there are still certain disadvantages, such as: First, the pulp is squeezed by the net and the breast roller at the breast roller and the centrifugal force generated by the high-speed rotation, so that the pulp can be dehydrated and concentrated, but for the pulp with high concentration of ink particles, fillers and other fine impurities, dehydration and concentration can only be achieved by increasing the rotation speed to increase the centrifugal force, but the high-speed operation state will cause the pulp to splash, affecting the working environment; Second, in order to increase the pulp dehydration speed, the surface of the rubber roller is often grooved, but the ink particles, fillers and other fine impurities will be hindered by the pulp layer during the removal process. In the dehydration and concentration process, the ink particles, fillers and other fine impurities are not completely removed, and the consistency of the pulp layer is poor. Summary of the invention

[0004] The object of the present invention is to provide a pulp processing device to solve the above-mentioned defects caused by the prior art.

[0005] A pulp processing equipment comprises a frame, a pulp flower, a pulp layer opening and repairing mechanism and an extrusion and rolling pulp washing mechanism, wherein the sulfur pulper is arranged on the frame, a white water discharge pipe is arranged at the other end of the frame, and a polyester net is also arranged in the frame, the pulp layer opening and repairing mechanism is installed on the frame and is used to first open and then repair the pulp layer, and the extrusion and rolling pulp washing mechanism is installed on the pulp layer opening and repairing mechanism and is used to centrifugally dehydrate and wash the pulp layer.

[0006] Preferably, the slurry layer patching mechanism includes a driving motor, a flaring piece and a patch head, the driving motor is installed on the frame through a mounting frame, a rocker is installed at the output end of the driving motor, a driving wheel is coaxially installed on the output shaft of the driving motor, a sliding rod is installed at the other end of the rocker, a lifting frame is slidably arranged in the frame, a slip ring is installed at the upper end of the lifting frame, a mounting seat is slidably arranged at the lower end of the slip ring, a spring is sleeved on the mounting seat on the slip ring, the flaring piece is symmetrically installed at the lower end of the mounting seat, and the patch head is symmetrically installed at the lower end of the lifting frame.

[0007] Preferably, the squeeze and wash pulping mechanism includes a breast roll, a couch roll and a water spray head, the breast roll is a symmetrical structure that is narrow in the middle and wide at both ends, the breast roll is rotatably mounted on the mounting frame, and a driven wheel is coaxially mounted on the end of the breast roll, the driven wheel is connected to the driving wheel through a synchronous belt, a scraper is also symmetrically mounted on the mounting frame, the water spray head is mounted on the scraper, a gear one is coaxially mounted on the other end of the breast roll, the couch roll is a symmetrical structure that is wide in the middle and narrow at both ends, the couch roll is rotatably mounted on the mounting frame and is placed below the breast roll, and a gear two meshing with gear one is coaxially mounted on the end of the couch roll.

[0008] Preferably, the polyester net is provided with an avoidance opening, and the avoidance opening cooperates with the patch head in the vertical direction.

[0009] Preferably, the projections of the expansion pieces in the vertical direction are placed on both sides of the middle of the breast roll and within the middle of the couch roll.

[0010] Preferably, the breast roll cooperates with the couch roll, and a gap formed therebetween tends to widen toward both sides.

[0011] The advantages of the present invention are:

[0012] By arranging a pulp layer opening and filling mechanism and an extrusion and washing mechanism on the frame, the output end of the driving motor drives the rocker and the driving wheel to rotate synchronously. Since the gap formed between the breast roll and the couch roll tends to widen toward both sides, the ink particles, fillers and other fine impurities located in the middle of the pulp layer can automatically diffuse to both sides of the pulp layer. Under the combined effect of the centrifugal force of the rotation of the breast roll and the couch roll and the extrusion method extending obliquely downward to both sides, even if the pulp with a high impurity concentration is processed, the dehydration and concentration operation can still be successfully completed without affecting the working environment;

[0013] At the same time, the rotation of the rocker will drive the slip ring to perform reciprocating lifting and lowering movements through the sliding rod. The expansion piece will touch the pulp layer below and then touch the surface of the crouching roller to complete the cutting action of the single-sided opening. The side end section of the middle opening pulp layer is exposed to the cleaning range, and the middle ink particles, fillers and other fine impurities blocked by the pulp layer can be completely removed. The processing is completed by opening and then restoring and filling, which can ensure the consistency of the pulp layer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] like Figures 1 to 5 As shown, a pulp processing equipment includes a frame 1, a pulp flower 2, a pulp layer opening and repairing mechanism 3 and an extrusion and washing mechanism 4, the sulfur pulper is arranged on the frame 1, a white water discharge pipe 5 is arranged at the other end of the frame 1, and a polyester net 6 is also arranged in the frame 1, the pulp layer opening and repairing mechanism 3 is installed on the frame 1, and is used to open the pulp layer first and then repair it, and the extrusion and washing mechanism 4 is installed on the pulp layer opening and repairing mechanism 3, and is used to centrifugally dehydrate and wash the pulp layer.

[0022] In this embodiment, the slurry layer patching mechanism 3 includes a driving motor 301, a flaring piece 302 and a patch head 303. The driving motor 301 is installed on the frame 1 through a mounting frame 304. A rocker 305 is installed at the output end of the driving motor 301. A driving wheel 306 is coaxially installed on the output shaft of the driving motor 301. A sliding rod 307 is installed at the other end of the rocker 305. A lifting frame 308 is slidably arranged in the frame 1. A slip ring 309 is installed at the upper end of the lifting frame 308. A mounting seat 310 is slidably installed at the lower end of the slip ring 309. A spring 311 is sleeved on the slip ring 309 on the mounting seat 310. The flaring piece 302 is symmetrically installed at the lower end of the mounting seat 310, and the patch head 303 is symmetrically installed at the lower end of the lifting frame 308.

[0023] It should be noted that the expansion piece 302 is an arc-shaped single-sided cutting edge, that is, when the sliding ring 309 slides to the lowermost position, the expansion piece 302 completes the opening of the pulp layer, and the opening part of the pulp layer does not fall off completely.

[0024] In this embodiment, the squeeze and wash pulping mechanism 4 includes a breast roll 41, a couch roll 42 and a water spray head 43. The breast roll 41 is a symmetrical structure that is narrow in the middle and wide at both ends. The breast roll 41 is rotatably mounted on the mounting frame 304, and a driven wheel 44 is coaxially mounted on the end of the breast roll 41. The driven wheel 44 is connected to the driving wheel 306 through a synchronous belt 45. A scraper 46 is also symmetrically mounted on the mounting frame 304. The water spray head 43 is mounted on the scraper 46. A gear 1 47 is coaxially mounted on the other end of the breast roll 41. The couch roll 42 is a symmetrical structure that is wide in the middle and narrow at both ends. The couch roll 42 is rotatably mounted on the mounting frame 304 and is placed below the breast roll 41. A gear 2 48 meshing with the gear 1 47 is coaxially mounted on the end of the couch roll 42.

[0025] In this embodiment, a relief opening is provided on the polyester net 6 , and the relief opening matches with the patch head 303 in the vertical direction.

[0026] In this embodiment, the projections of the expansion pieces 302 in the vertical direction are placed on both sides of the middle of the breast roll 41 and are placed within the middle range of the couch roll 42 .

[0027] In addition, the breast roll 41 cooperates with the couch roll 42, and a gap formed therebetween tends to widen toward both sides.

[0028] Working process and principle: During the use of the present invention, firstly, the paper pulp to be processed is placed into the device through the pulper 2, and the driving motor 301 is started to make its output end drive the rocker 305 and the driving wheel 306 to rotate synchronously. The rotation of the driving wheel 306 will drive the driven wheel 44 to rotate through the synchronous belt 45, and in the meshing state of the two gears 1 47 and the gear 2 48 at the end, it will drive the breast roller 41 and the couch roller 42 to rotate synchronously in the opposite direction, so that the pulp is transported forward in the gap between the breast roller 41 and the couch roller 42 in the form of a pulp layer, and because the gap formed between the breast roller 41 and the couch roller 42 tends to widen to both sides, the ink particles, fillers and other fine impurities located in the middle of the pulp layer can automatically diffuse to both sides of the pulp layer;

[0029] At the same time, under the rotation of the rocker 305, the sliding ring 309 will be driven to perform a reciprocating lifting action through the sliding rod 307. The downward movement of the sliding ring 309 will drive the two flaring pieces 302 which are adjustable and arranged on the mounting seat 310 to move downward synchronously. Since the projections of the flaring pieces 302 in the vertical direction are placed on both sides of the middle of the breast roller 41 and are placed in the middle range of the couch roller 42, the flaring pieces 302 will not have a rigid contact with the rotating breast roller 41, but will touch the surface of the couch roller 42 after contacting the pulp layer below, completing the cutting action of the single-sided opening, and under the elastic buffering action of the spring 311, the cutting edge of the flaring piece 302 will not cause excessive damage to the surface of the couch roller 42, and the pulp layer with an opening in the middle is cleaned by a plurality of spray heads 43 arranged side by side, and the side end section of the pulp layer with an opening in the middle is exposed in the cleaning range, so that the ink particles, fillers and other fine impurities in the middle that are blocked by the pulp layer can be smoothly removed;

[0030] As the rocker 305 continues to rotate, the slip ring 309 is driven to rise, and the patch head 303 is driven to rise synchronously through the lifting frame 308, and the upper end surface of the patch head 303 completes the pushing and restoring of the opening part of the pulp layer that has not completely fallen off.

[0031] Based on the above, the present invention sets a pulp layer opening and filling mechanism 3 and a squeezing and washing mechanism 4 on the frame 1, and the output end of the driving motor 301 drives the rocker 305 and the driving wheel 306 to rotate synchronously. Since the gap formed between the breast roller 41 and the couch roller 42 tends to widen toward both sides, the ink particles, fillers and other fine impurities located in the middle of the pulp layer can automatically diffuse toward both sides of the pulp layer. Under the combined effect of the centrifugal force of the rotation of the breast roller 41 and the couch roller 42 and the extrusion method extending obliquely downward toward both sides, even if the pulp with a high impurity concentration is processed, the dehydration and concentration operation can still be successfully completed without affecting the working environment.

[0032] At the same time, the rotation of the rocker 305 will drive the sliding ring 309 to perform reciprocating lifting and lowering movements through the sliding rod 307. The flaring piece 302 contacts the pulp layer below and then touches the surface of the crouching roller 42, completing the cutting action of the single-sided opening. The side end section of the middle opening pulp layer is exposed to the cleaning range, and the middle ink particles, fillers and other fine impurities blocked by the pulp layer can be completely removed. The processing is completed by opening and then restoring and filling, which can ensure the consistency of the pulp layer.

[0033] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
