Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a fiber dispersion device for papermaking. Background Technology

[0002] Paper is a thin sheet material made from plant fibers or other fiber raw materials through processes such as pulping, papermaking, and drying. It is an essential basic product in daily life and industrial production. During the papermaking process, paper fibers must be dispersed. Paper formation depends on the fibers being evenly suspended and interwoven in water. If the fibers are not sufficiently dispersed and clump together, it will lead to uneven fiber distribution during papermaking, resulting in paper with inconsistent thickness and a loose structure. Furthermore, undispersed fiber clumps will hinder the even loss of moisture in subsequent processes, potentially causing defects such as deformation and cracking after the paper has dried.

[0003] Currently, most fiber dispersion equipment for papermaking on the market adopts a single dispersion component and a single-layer filtration structure. That is, the fiber raw material is processed by only one dispersion component, and the fiber is separated by the single mechanical action of this component. The filtration stage is only set with a single filter screen, which can only intercept large particulate impurities in the raw material. However, this single-layer filtration structure is difficult to solve the problems of fiber agglomeration and impurity residue in traditional equipment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fiber dispersion device for papermaking, which aims to improve the problem that the single-layer filtration structure is difficult to solve in traditional equipment, which is prone to fiber agglomeration and impurity residue.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiber dispersion device for papermaking, comprising a housing, an inlet fixedly connected to the inner wall of the housing, a motor fixedly connected to the outer wall of the housing, a drive shaft fixedly installed at the output end of the motor, a large bevel gear fixedly connected to the outer wall of the drive shaft, a small bevel gear meshing with the tooth end of the large bevel gear, a spiral mixing cylinder fixedly connected to the outer wall of the small bevel gear, a large-diameter filter screen rotatably connected to the outer wall of the spiral mixing cylinder, a grinding drum fixedly connected to the outer wall of the small bevel gear, a small-diameter filter screen rotatably connected to the outer wall of the grinding drum, a stirring cylinder fixedly connected to the outer wall of the small bevel gear, a medium-diameter filter screen rotatably connected to the outer wall of the stirring cylinder, a water filtration assembly fixedly installed on the outer wall of the medium-diameter filter screen, and the water filtration assembly being used to filter liquid and retain paper fibers.

[0006] Preferably, the water filtration assembly includes a storage bin, the outer wall of which is fixedly fitted with a medium-diameter filter screen, the outer wall of which is fixedly connected to the inner wall of the housing, the inner wall of which is slidably connected with a pull plate, and the inner wall of which is fixedly connected with a drain outlet.

[0007] Preferably, the outer wall of the drive shaft is rotatably connected to the inner wall of the housing, and the outer wall of the large-diameter filter screen is fixedly connected to the inner wall of the housing.

[0008] Preferably, the outer wall of the spiral mixing cylinder is rotatably connected to the inner wall of the housing, and the outer wall of the grinding drum is rotatably connected to the inner wall of the housing.

[0009] Preferably, the outer wall of the small-diameter filter screen is fixedly connected to the inner wall of the housing, and the outer wall of the stirring drum is rotatably connected to the inner wall of the housing.

[0010] Preferably, a protective shell is fixedly connected to the outer wall of the housing, a crank handle is rotatably connected to the outer wall of the protective shell, a small bevel gear II is fixedly connected to the outer wall of the crank handle, a support bracket is rotatably connected to the outer wall of the crank handle, a large bevel gear II is meshed with the tooth end of the small bevel gear II, the outer wall of the large bevel gear II is rotatably connected to the outer wall of the support bracket, a threaded rod is fixedly connected to the outer wall of the large bevel gear II, a lower pressure block is rotatably connected to the outer wall of the threaded rod, the outer wall of the lower pressure block is attached to the upper surface of the pull plate, a base plate is fixedly connected to the outer wall of the support bracket, and the outer wall of the base plate is slidably connected to the lower surface of the pull plate.

[0011] Preferably, the outer wall of the support bracket is fixedly connected to the inner wall of the protective shell, and the outer wall of the support bracket is rotatably connected to the outer wall of the small bevel gear II.

[0012] Preferably, the outer wall of the threaded rod is rotatably connected to the inner wall of the support bracket, and the outer wall of the lower pressure block is slidably connected to the outer wall of the support bracket.

[0013] This utility model has the following beneficial effects: In this invention, when fiber dispersion is required, a motor drives the transmission shaft to rotate, which in turn links the spiral mixing drum, grinding drum, and stirring drum to disperse the fibers step by step. The fibers are then filtered twice through filter screens of varying diameters, thus solving the problems of fiber clumping and impurity residue in traditional equipment and ensuring papermaking quality. In this invention, when shaping the fiber, the crank handle drives the small bevel gear two to rotate, which in turn drives the large bevel gear two to rotate the threaded rod, thereby causing the lower pressure block to move down and extrude the paper fiber with the attached liquid to complete the shaping. When it is necessary to close the storage hopper, the crank handle is cranked in the opposite direction to move the lower pressure block up. The pull plate resets and closes the hopper under no downward pressure and restricted by the inner wall of the storage hopper, thereby achieving the effects of convenient shaping and safe storage of dispersed fibers, reducing equipment switching costs and raw material loss.

[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides a fiber dispersion device for papermaking, comprising a housing 1, an inlet 2 fixedly connected to the inner wall of the housing 1, a motor 3 fixedly connected to the outer wall of the housing 1, a transmission shaft 4 fixedly installed at the output end of the motor 3, a large bevel gear 5 fixedly connected to the outer wall of the transmission shaft 4, a small bevel gear 6 meshing with the tooth end of the large bevel gear 5, a spiral mixing cylinder 7 fixedly connected to the outer wall of the small bevel gear 6, a large-diameter filter screen 8 rotatably connected to the outer wall of the spiral mixing cylinder 7, a grinding drum 9 fixedly connected to the outer wall of the small bevel gear 6, a small-diameter filter screen 10 rotatably connected to the outer wall of the grinding drum 9, a stirring cylinder 11 fixedly connected to the outer wall of the small bevel gear 6, a medium-diameter filter screen 12 rotatably connected to the outer wall of the stirring cylinder 11, a water filtration assembly fixedly installed on the outer wall of the medium-diameter filter screen 12, the water filtration assembly being used to filter liquid and retain paper fibers; Specifically, the raw materials first enter through the feed inlet 2, then the motor 3 fixed on the casing 1 drives the transmission shaft 4 to rotate. The rotation of the transmission shaft 4 drives the large bevel gear 5 to rotate. The casing 1 restricts and guides the transmission shaft 4, ensuring that it remains in a circular rotation state during its rotation and does not deviate or fall off. This causes the rotation of the large bevel gear 5 to drive the small bevel gear 6 to rotate. The rotation of the small bevel gear 6 simultaneously drives the spiral mixing drum 7, the grinding drum 9, and the stirring drum 11 to rotate. During the rotation of the spiral mixing drum 7, the raw materials entering the casing 1 are initially mixed and dispersed. The large-diameter filter screen 8, which is rotatably connected to its outer side, can effectively intercept larger particles of impurities. The grinding drum 9 further grinds and refines the initially mixed raw materials, making their fiber structure more loose. The small-diameter filter screen 10 performs secondary filtration on the ground raw materials. When the mixing drum 11 rotates, it fully stirs the ground raw materials to ensure that the fibers are evenly dispersed. The casing 1 provides support for the large-diameter filter screen 8, the small-diameter filter screen 10, and the medium-diameter filter screen 12, ensuring the particle size at each stage of raw material filtration. The medium-diameter filter screen 12 not only supports the water filtration assembly but also performs final filtration on the stirred raw materials, ensuring that the output paper fibers are fully dispersed and working with the water filtration assembly to remove subsequent paper fibers.

[0018] Reference Figure 2 and Figure 3 The water filtration assembly includes a storage bin 13, with a medium-diameter filter screen 12 fixedly installed on the outer wall of the storage bin 13. The outer wall of the storage bin 13 is fixedly connected to the inner wall of the housing 1. A pull plate 14 is slidably connected to the inner wall of the storage bin 13. A drain outlet 15 is fixedly connected to the inner wall of the storage bin 13. Specifically, the paper fibers filtered through the medium-diameter filter screen 12 will fall into the storage bin 13. At this time, the liquid accumulated in the storage bin 13 can be discharged through the drain outlet 15. The inner wall of the drain outlet 15 is equipped with a professional filter plate to achieve solid-liquid separation. When it is necessary to remove the clump of paper fibers, simply slide the pull plate 14 to remove the paper fibers collected in the storage bin 13. The operation is convenient and quick.

[0019] Reference Figure 2 and Figure 3 The outer wall of the drive shaft 4 is rotatably connected to the inner wall of the housing 1, and the outer wall of the large-diameter filter screen 8 is fixedly connected to the inner wall of the housing 1. Specifically, the housing 1 provides support for the drive shaft 4 and the large-diameter filter screen 8, ensuring that the drive shaft 4 is not affected by external factors during rotation and will not shake or deviate. At the same time, the large-diameter filter screen 8 can also stably intercept larger particles of impurities, providing qualified raw materials for subsequent grinding and mixing.

[0020] Reference Figure 2 and Figure 3 The outer wall of the spiral mixing drum 7 is rotatably connected to the inner wall of the housing 1, and the outer wall of the grinding drum 9 is rotatably connected to the inner wall of the housing 1. Specifically, the support provided by the housing 1 to the spiral mixing cylinder 7 and the grinding roller 9 ensures that the spiral mixing cylinder 7 can initially mix and disperse the raw materials during rotation, while the grinding roller 9 further disperses the fibers of the raw materials and effectively improves the efficiency of fiber dispersion.

[0021] Reference Figure 2 and Figure 3 The outer wall of the small-diameter filter screen 10 is fixedly connected to the inner wall of the housing 1, and the outer wall of the stirring drum 11 is rotatably connected to the inner wall of the housing 1. Specifically, the small-diameter filter screen 10 and the stirring cylinder 11 are supported by the housing 1. The small-diameter filter screen 10 can filter out fine impurities after grinding, while the stirring cylinder 11 further breaks up the fiber clumps during rotation, making the fibers more evenly and finely dispersed, thereby improving the quality of paper fibers.

[0022] Reference Figure 1 , Figure 2 and Figure 4A protective shell 16 is fixedly connected to the outer wall of the housing 1. A crank handle 17 is rotatably connected to the outer wall of the protective shell 16. A small bevel gear 18 is fixedly connected to the outer wall of the crank handle 17. A support bracket 20 is rotatably connected to the outer wall of the crank handle 17. A large bevel gear 19 is meshed with the tooth end of the small bevel gear 18. The outer wall of the large bevel gear 19 is rotatably connected to the outer wall of the support bracket 20. A threaded rod 21 is fixedly connected to the outer wall of the large bevel gear 19. A lower pressure block 22 is rotatably connected to the outer wall of the threaded rod 21. The outer wall of the lower pressure block 22 is attached to the upper surface of the pull plate 14. A base plate 23 is fixedly connected to the outer wall of the support bracket 20. The outer wall of the base plate 23 is slidably connected to the lower surface of the pull plate 14. Specifically, the crank 17, which is restricted to the protective shell 16, drives the small bevel gear 18 to rotate, thereby driving the large bevel gear 19 to rotate through meshing. The protective shell 16 and the support bracket 20 provide support for the small bevel gear 18 and the large bevel gear 19, ensuring that the small bevel gear 18 and the large bevel gear 19 are not affected by external factors during their meshing motion. This causes the rotation of the large bevel gear 19 to drive the threaded rod 21 to rotate. The rotation of the threaded rod 21 causes the lower pressure block 22 to move downward, thus extruding the liquid adhering to the paper fibers and completing the shaping process. The support bracket 20 provides guidance and restriction for the lower pressure block 22, ensuring that the lower pressure block 22 is always in a straight line and is not affected by external forces to deviate or fall off. The base plate 23 fixedly connected to the support bracket 20 is slidably connected to the lower surface of the pull plate 14. At the same time, the support bracket 20 provides support for the pull plate 14, thereby facilitating the opening of the storage bin 13 to take out the paper fibers inside. When it is necessary to close the storage bin 13, the crank handle 17 is turned in the opposite direction. The rotation of the threaded rod 21 causes the lower pressure block 22 to move upward. The pull plate 14 returns to its original position without downward pressure and under the restriction of the inner wall of the storage bin 13, thereby closing the storage bin 13.

[0023] Reference Figure 4 The outer wall of the support bracket 20 is fixedly connected to the inner wall of the protective shell 16, and the outer wall of the support bracket 20 is rotatably connected to the outer wall of the small bevel gear 18. Specifically, by fixing the support bracket 20 to the inner wall of the protective shell 16, it is ensured that the small bevel gear 18 is not affected by external forces during rotation and will not deviate or shake due to uneven force, thereby ensuring the meshing transmission with the large bevel gear 19. At the same time, the rotational connection between the support bracket 20 and the outer wall of the small bevel gear 18 further improves the stability of the equipment transmission.

[0024] Reference Figure 4 The outer wall of the threaded rod 21 is rotatably connected to the inner wall of the support bracket 20, and the outer wall of the lower pressure block 22 is slidably connected to the outer wall of the support bracket 20. Specifically, the rotatable connection of the threaded rod 21 to the inner wall of the support bracket 20 ensures that the threaded rod 21 is not affected by external factors when it rotates, so that it will not deviate or fall off. At the same time, the sliding connection of the lower pressure block 22 to the outer wall of the support bracket 20 provides a certain movement trajectory for the lower pressure block 22, so that it can maintain a straight line movement when it moves downward to squeeze the paper fibers, and there will be no deviation or jamming.

[0025] Working principle: When it is necessary to disperse the fibers used in papermaking, the raw material is first put in through the feed inlet 2. The motor 3 is started to drive the transmission shaft 4 to rotate, which in turn drives the large bevel gear 5 to rotate, which in turn drives the small bevel gear 6 to rotate. The rotation of the small bevel gear 6 causes the spiral mixing drum 7, the grinding drum 9, and the stirring drum 11 to rotate respectively. During the rotation of the spiral mixing drum 7, the raw material entering the machine casing 1 is initially mixed and dispersed. The large-diameter filter screen 8 can effectively intercept larger particles of impurities. The grinding drum 9 further disperses the fibers of the raw material, making the fiber dispersion more complete. The small-diameter filter screen 10 performs secondary filtration of the raw material. When the stirring drum 11 rotates, it fully stirs the ground raw material to ensure that the output paper fibers are fully dispersed. It also works with the water filtration component to remove the subsequent paper fibers, thereby achieving multi-stage linkage dispersion and solving the pain points of fiber agglomeration and impurity residue affecting papermaking quality in traditional dispersion equipment. When it is necessary to press and plasticize the dispersed fibers, the crank handle 17 drives the small bevel gear 18 to rotate, which in turn drives the large bevel gear 19 to rotate, causing the threaded rod 21 to rotate. The rotation of the threaded rod 21 causes the pressing block 22 to move downward, and completes the extrusion of the liquid attached to the paper fibers to complete the shaping. When it is necessary to close the storage hopper 13, the crank handle 17 is turned in the opposite direction. Through the above transmission relationship, the pressing block 22 moves upward, and the pull plate 14 returns to its original position without downward pressure and under the restriction of the inner wall of the storage hopper 13, thereby closing the storage hopper 13. This achieves the effect of convenient shaping and safe storage of dispersed fibers, reducing equipment switching costs and raw material loss. This fiber dispersion equipment not only achieves multi-stage linkage dispersion, solving the pain points of fiber agglomeration and impurity residue affecting papermaking quality in traditional dispersion equipment, but also achieves convenient shaping and safe storage of dispersed fibers, reducing equipment switching costs and raw material losses.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
