Description

Technical Field

[0001] This utility model relates to the field of mechanical product technology, specifically to a stirring-type pulp board defiberization device. Background Technology

[0002] Wet defiberization is a process that separates or disperses incompletely dissolved paper scraps or fiber clumps from raw materials such as waste paper after they have been broken down, screened, purified, or thermally dispersed into single, wet, and relatively fibrous fibers without cutting them, causing damage, or reducing their strength. This technology is widely used in the papermaking industry.

[0003] The existing publicly available technology, application number CN200720090252.3, describes a wood pulp board defibering and fiber-adding device. This device mainly consists of an automatic quantitative feeding mechanism and a defiber connected to it, mounted on a main frame. The defiber is connected to a dewatering device via a screw conveyor, and the dewatering device is connected to a mixer via a scraper conveyor. The mixer is connected to a glue-forming device via a pump, and further connected to a storage tank via another pump. Because the wood pulp fiber defibering is completed under water immersion and water flow impact shearing, there is no fiber breakage, resulting in high utilization. Furthermore, since the wet-fibered fibers can be uniformly suspended in the glue solution, mixing them with tobacco powder greatly improves the mixing uniformity of tobacco powder and fibers, resulting in tobacco sheets without speckles. Moreover, all comprehensive quality technical indicators meet national standards. Additionally, it has a high degree of automation, can support on-line production, meets the requirements of automated tobacco sheet production lines, and is convenient to operate and maintain.

[0004] However, existing fiber disintegration devices do not have a grading function during use, making it impossible to effectively evaluate the degree of disintegration. On the other hand, they cannot release the disintegrated pulp as needed while disintegrating, which may cause damage to some fiber microstructures during the long disintegration process, resulting in a reduction in the overall treatment effect. Moreover, some materials are prone to deposit or adhere to the inner wall during fiber disintegration, preventing them from contacting the disintegration structure and thus resulting in insufficient treatment, affecting the overall use effect.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a stirring-type pulp board defiberization device, which has the advantages of good defiberization effect, controlled defiberization degree, and thorough processing, thereby solving the problems mentioned in the background technology.

[0008] (II) Technical Solution

[0009] To achieve the advantages of good fiber unwinding effect, controlled fiber unwinding degree, and thorough treatment, the specific technical solution adopted by this utility model is as follows:

The screening plate has an arc-shaped structure.

[0011] Furthermore, a drive shaft is installed in the middle of the fiber debonding chamber. One end of the drive shaft passes through one side of the machine body and is connected to a motor. Connecting rods are symmetrically installed at the top of the drive shaft surface. A side scraper is installed at one end of the connecting rod and contacts the inner wall of the machine body.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a stirring-type pulp board defiberization device, which has the following beneficial effects:

[0020] (1) This utility model adopts a sieve plate and sieve holes. During operation, the sieve chamber at the bottom of the fiber debonding chamber is equipped with multiple sets of sieve plates. During the wiring process, the sieve holes on the surface of the corresponding sieve plates can be used to sieve the fibers by raising and lowering the corresponding sieve plates. Since the inner sieve holes are smaller and the outer sieve holes are larger, multiple sieve operations can be achieved by raising and lowering the inner sieve plates first and then raising and lowering the outer sieve plates. This allows fibers of different degrees to be discharged step by step, thereby meeting the different needs of personnel, avoiding excessive fiber breakage due to long-term operation, ensuring the fiber composite subsequent processing needs, meeting the different usage needs of personnel, improving the practicality of the device, and having the advantage of fiber debonding degree control.

During operation, the rotation of the drive shaft inside the defiber chamber can drive the striking rod, the first stirring blade, and the second stirring blade to rotate at high speed. At this time, the high-speed rotating blades and rods can strike the pulp board, thereby realizing the defiber separation operation. At the same time, when the drive shaft rotates at high speed, the side scrapers and bottom scrapers on its side and bottom can scrape the side wall and bottom of the machine body, scraping the fibers attached to and settled at the bottom, so that these fibers can also be fully processed. Furthermore, the second stirring blade has a V-shaped structure, which can generate a vortex when rotating at high speed, thereby lifting the liquid and fibers at the bottom through the vortex, avoiding sedimentation that affects the processing effect. It has the advantages of good defiber separation effect and thorough processing. Attached Figure Description

[0029] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0030] According to an embodiment of the present invention, a stirring-type pulp board defiberization device is provided.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a stirring pulp board defibering device according to an embodiment of the present invention includes a body 1 and support legs 13. A defibering chamber 16 is provided at the top of the body 1, and a screening chamber 17 is provided at the bottom of the body 1. Several sets of screening plates 14 are symmetrically slidably connected inside the screening chamber 17. Several sets of screen holes 12 are evenly opened on the surface of the screening plates 14. One end of the screening plate 14 passes through one side of the body 1 and is connected to a cylinder 10. The size of the screen holes 12 gradually increases from the inside to the outside. The screening plate 14 has an arc-shaped structure, but the size of the arc-shaped structure is smaller than that of the semi-circular structure, thereby ensuring that it can move up and down in the body 1 without affecting the strength and integrity of the entire structure of the body 1.

[0032] In one embodiment, a drive shaft 6 is installed in the middle of the fiber dissolving chamber 16. One end of the drive shaft 6 passes through one side of the machine body 1 and is connected to the motor 5. A connecting rod 3 is symmetrically installed at the top of the surface of the drive shaft 6. A side scraper 2 is installed at one end of the connecting rod 3 and contacts the inner wall of the machine body 1. A bottom scraper 15 is installed around the bottom of the drive shaft 6 and contacts the bottom surface of the machine body 1. Several sets of first stirring blades 7, striking rods 8 and second stirring blades 9 are respectively installed between the side scraper 2 and the bottom scraper 15 at the surface of the drive shaft 6. The second stirring blades 9 have a V-shaped structure.

[0033] In one embodiment, several sets of support legs 13 are symmetrically installed on both sides of the bottom of the body 1. The support legs 13 can fix the entire device, thereby enhancing the overall stability of use.

[0034] In one embodiment, the top of the machine body 1 is symmetrically provided with a feed port 4. The feed port 4 is provided to facilitate the addition of raw materials and facilitate subsequent processing operations.

[0035] In one embodiment, the machine body 1 is composed of two sets of cylinders, with the upper cylinder being smaller than the lower cylinder and interconnected. The upper and lower dimensions of the machine body 1 are set to facilitate the installation and adjustment of the screening plate 14.

[0036] In one embodiment, the surface of the side scraper 2 and the surface of the bottom scraper 15 are both covered with rubber. The rubber covering is to avoid direct friction between metals, which would cause excessive wear on the machine body 1, thereby ensuring its service life. At the same time, it can effectively reduce operating noise and facilitate better use.

[0037] In one embodiment, discharge pipes 11 are symmetrically provided at the bottom of both sides of the machine body 1. The discharge pipes 11 are provided to discharge the fibers, which facilitates the subsequent drying operation and allows personnel to use the fibers after defibering.

[0038] In one embodiment, a channel is provided on the surface of the machine body 1 for the sieve plate 14 to move, and a sealing gasket is provided on the surface of the channel. The channel is provided to facilitate the up and down movement of the sieve plate 14, thereby achieving different sieve effects. The sealing gasket is provided to ensure the sealing of the connection and prevent liquid leakage. At the same time, the sieve required can be provided by the liquid flow generated when the drive shaft 6 rotates. When the liquid carries the fibers and impacts the sieve plate 14, the qualified fibers can be separated by the sieve holes 12, while the unqualified fibers can be blocked and carried by the liquid.

[0039] Working Principle: In actual use, the pulp board requiring defibering and the liquid needed for wet processing are added to the machine body 1 through the feed inlet 4. Then, the rotation of the drive shaft 6 inside the defibering chamber 16 drives the striking rod 8, the first stirring blade 7, and the second stirring blade 9 to rotate at high speed. At this time, the high-speed rotating blades and rods can strike the pulp board, thereby achieving the defibering operation. At the same time, when the drive shaft 6 rotates at high speed, the side scrapers 2 and bottom scrapers 15 can scrape the side walls and bottom of the machine body 1, scraping the fibers attached to and settled at the bottom, so that these fibers can also be fully processed. Furthermore, the second stirring blade 9 has a V-shaped structure, which can generate a vortex when rotating at high speed, thereby driving the pulp board to defiber through the vortex. The device elevates the liquid and fibers at the bottom to prevent sedimentation from affecting the processing effect. Furthermore, the screening chamber 17 at the bottom of the fiber-debonding chamber 16 is equipped with multiple screening plates 14. During wiring, the corresponding screening plates 14 can be raised or lowered to allow the screen holes 12 on their surfaces to screen the fibers. Since the inner screen holes 12 are smaller than the outer screen holes 12, multiple stages of screening can be achieved by first raising and lowering the inner screening plates 14 and then raising and lowering the outer screening plates 14. This allows fibers of different strengths to be discharged step by step, meeting different user needs and preventing excessive fiber breakage due to prolonged operation. This ensures the fiber composite meets subsequent processing requirements, improves the practicality of the device, and the overall device has the advantages of good fiber-debonding effect, controlled fiber debonding degree, and thorough processing.
