Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking, and in particular relates to a pulp recovery device for papermaking. Background Art

[0002] Papermaking is divided into two forms: mechanical and manual. Mechanical papermaking is carried out continuously on a papermaking machine. Pulp suitable for paper quality is diluted with water to a certain concentration, and initially dehydrated on the wire section of the papermaking machine to form wet paper sheets. The wet paper sheets are then pressed and dehydrated, and then dried into paper. Manual papermaking uses a frame with a bamboo screen, polyester mesh or copper mesh to make fibers dispersed and suspended in water into wet paper sheets. The wet paper sheets are pressed and dehydrated, and then sun-dried or baked into paper.

[0030] Among them, the rotating mechanism 4 includes a motor bracket 401, a drive motor 402, a rotating shaft 403, a disc 404, a first bearing 405 and a positioning groove 406. The bottom of the motor bracket 401 is fixedly connected to the upper surface of the base plate 1, the upper surface of the motor bracket 401 is fixedly connected to the bottom of the drive motor 402, the output end of the drive motor 402 is fixedly connected to the bottom end of the rotating shaft 403, the surface of the rotating shaft 403 is fixedly connected to the inner wall of the disc 404, the surface of the disc 404 is rotatably connected to the inner wall of the hollow plate 3 through the first bearing 405, and the positioning groove 406 is opened on the upper surface of the disc 404. The inner wall of the positioning groove 406 and the upper surface of the disc 404 are both in contact with the surface of the double-layer separation cylinder 5.

[0031] The double-layer separation cylinder 5 includes a first cylinder 501, a sealing plate 502, a filter cylinder 503, a second bearing 504, a second connecting column 505, an iron ring 506, a drainage hole 507, a positioning block 508 and a handle 509.

It is fixedly connected to the surface of the second bearing 504, the bottom of the iron ring 506 is in contact with the upper surface of the electromagnet 9, and after the electromagnet 9 absorbs the iron ring 506 through the second bearing 504, the iron ring 506 no longer rotates with the first cylinder 501, and the drainage hole 507 is opened on the surface of the first cylinder 501. The liquid in the first cylinder 501 is discharged through the drainage hole 507 and the drainage pipe 7 in turn, the bottom of the sealing plate 502 is in contact with the upper surface of the disc 404, the bottom of the sealing plate 502 is fixedly connected to the upper surface of the positioning block 508, the surface of the positioning block 508 is in contact with the inner wall of the positioning groove 406, and the left and right sides of the first cylinder 501 are fixedly connected to the side of the handle 509.

[0033] It should be noted that when the electromagnet 9 is turned on, the first cylinder 501 can be fixed in the second cylinder 6 by the suction force of the iron ring 506 of the electromagnet 9, and through the cooperation of the positioning groove 406 and the positioning block 508, the driving motor 402 on the rotating mechanism 4 can drive the first cylinder 501 to rotate, and the pressing plate 1003 is located directly above the filter cylinder 503, and the pressing plate 1003 can press the slurry in the filter cylinder 503 through the first hydraulic push rod 1002.

[0034] like Figures 1 to 10 As shown, the top of the inner wall of the first U-shaped plate 1001 and the upper surface of the bottom plate 1 are fixedly connected to the second U-shaped plate 11, the top of the inner wall of the second U-shaped plate 11 is fixedly connected to the slide rail 12, the surface of the slide rail 12 is slidably connected to the slider 13, the back of the slider 13 and the inner wall of the second U-shaped plate 11 are fixedly connected to the second hydraulic push rod 14, the bottom of the slider 13 is fixedly connected to the third hydraulic push rod 15, the bottom of the third hydraulic push rod 15 is fixedly connected to the first connecting block 16, the inner wall of the first connecting block 16 is fixedly connected to the traction rope 17, one end of the traction rope 17 is fixedly connected to the second connecting block 18, and the bottom of the second connecting block 18 is fixedly connected to the hook 19.

[0035] It should be noted that, through the cooperation of the slide rail 12 and the slider 13, the third hydraulic push rod 15 can only move forward and backward, and the second hydraulic push rod 14 controls the forward and backward movement of the third hydraulic push rod 15, and the third hydraulic push rod 15 controls the up and down movement of the first connecting block 16. When the hook 19 is hung on the handle 509, the double-layer separation cylinder 5 can be lifted by the third hydraulic push rod 15, and the lifted double-layer separation cylinder 5 can be moved up and down by the second hydraulic push rod 14.

[0036] The working principle of the present invention is as follows: first, an empty double-layer separation cylinder 5 is placed in the second cylinder 6, and the positioning block 508 is inserted into the positioning groove 406. Then, by turning on the electromagnet 9, the electromagnet 9 generates suction on the iron ring 506, and the suction of the electromagnet 9 on the iron ring 506 makes it impossible for the positioning block 508 to be separated from the positioning groove 406.

[0037] Then, the slurry to be separated is poured into the filter cylinder 503, and the pressing plate 1003 is controlled to move upward by the first hydraulic push rod 1002, and the slurry in the filter cylinder 503 is filtered by the downward moving pressing plate 1003. At the same time, when the driving motor 402 is turned on, the disc 404 is rotated by the driving motor 402, and the double-layer separation cylinder 5 rotates with the disc 404 through the cooperation of the positioning groove 406 and the positioning block 508. At this time, the slurry in the filter cylinder 503 is centrifugally separated by the rotating filter cylinder 503. During the separation process, the separated liquid is discharged through the drainage hole 507 and the drainage pipe 7 in turn.

[0038] When the slurry separation is completed, the drive motor 402 is turned off, and the pressing plate 1003 is returned to the initial position through the first hydraulic push rod 1002. Then, the hook 19 is hung on the handle 509, and through the cooperation of the second U-shaped plate 11, the slide rail 12, the slider 13, the second hydraulic push rod 14, the third hydraulic push rod 15, the first connecting block 16, the traction rope 17, the second connecting block 18 and the hook 19, the double-layer separation cylinder 5 on the hollow plate 3 is hoisted onto the cart on the bottom plate 1.

[0039] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
