Description

Technical Field

[0001] The invention belongs to the technical field of textile equipment, and in particular relates to a fiber slurry stirring device for fabric production. Background Art

[0002] The fabric production process includes winding, warping, sizing, drawing-in, weaving, and finishing. Sizing refers to the process of applying sizing agent to the warp yarn to improve its weavability. During the sizing process of the warp yarn, the impurity fibers on the surface fall into the sizing pool. Over time, a large number of fine and short fibers are present in the raw pulp in the sizing pool, affecting the effect of subsequent sizing. Since the raw pulp has a certain viscosity, conventional filtering devices lack continuous and efficient filtering effects. In addition, in order to keep the raw pulp uniform during sizing, continuous stirring is required, and the stirring process will cause the fine and short fibers to roll continuously in the sizing pool and adhere to the warp yarn. Summary of the Invention

[0003] The purpose of the present invention is to provide a fiber slurry stirring device for fabric production in order to solve the above problems.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0005] A fiber pulp stirring device for fabric production includes a pulp pool, a stirring and filtering assembly, and a cleaning structure. The stirring and filtering assembly includes a filter cartridge arranged at the bottom end of the pulp pool and driven to rotate by a motor. The outer surface of the filter cartridge is provided with a spoke plate for centrifugation. The cleaning structure includes a fixed arm arranged on the side wall of the pulp pool and extending into the filter cartridge. The fixed arm has a U-shaped cross-section and is provided with a sliding plate driven by a cylinder. The surface of the sliding plate is provided with at least two one-way hinges along the sliding direction. The one-way hinges are all hinged to a cleaning strip via a hinged rod. The outer surface of the cleaning strip is provided with an elastic cleaning head that contacts the inner wall of the filter cartridge.

[0006] As a further optimization scheme of the present invention, the interior of the raw pulp pool is divided into two upper and lower areas by a mesh, the upper end is the sizing pool, and the lower end is the stirring pool. The stirring area and the sizing area are separated by the mesh to prevent the stirring process from affecting the warp yarn.

[0007] As a further optimization scheme of the present invention, the filter cartridge is rotatably arranged at the bottom end of the raw pulp pool through a large bearing part, and the motor is arranged outside the raw pulp pool, and the power is transmitted through the rotating shaft and gears. The outer wall of the filter cartridge is provided with a gear ring corresponding to the gear. By setting up a motor drive, the filter cartridge can rotate at high speed, and generate centrifugal force through the spoke plate to throw out the raw pulp, so that the raw pulp passes through the side wall of the filter cartridge and applies pressure for filtration.

[0008] As a further optimization scheme of the present invention, baffles are provided on the upper end of the fixed arm along both sides of the cleaning strip, wherein the baffle on one side contacts the inner wall of the filter cartridge, and a gap is left between the baffle on the other side and the inner wall of the filter cartridge. Since the filter cartridge rotates at a high speed, in order to collect the fibers scraped off by the cleaning head, the movement of the fibers is restricted by setting baffles so that they remain between the two baffles, making it convenient for them to converge through the reciprocating motion of the cleaning strip.

[0009] As a further optimization scheme of the present invention, a collecting trough is provided on the side wall of the raw pulp pool. The collecting trough penetrates into the interior of the raw pulp pool and is connected to the fixed arm. The cross-section of the collecting trough is a square tubular structure. The collected fiber clusters are collected and stored by setting the collecting trough. At the same time, the collecting trough is provided as a cleaning window, and cleaning does not affect normal operation.

[0010] As a further optimization scheme of the present invention, one end of the filter cartridge is close to the end of the collecting tank, which is used to reduce the turbulence at the connection between the collecting tank and the fixed arm, prevent the turbulence from affecting the gathered fiber clusters, and make the fiber clusters converge to the end under the action of the cleaning strip, which is convenient for collection and cleaning.

[0011] As a further optimization scheme of the present invention, the end of the fixed arm is also provided with a support structure for supporting the cleaning strip, and the support structure includes a slope arranged inside the fixed arm, a slide cylinder is arranged at the lower end of the cleaning strip, and a support foot corresponding to the slope is telescopically arranged at the lower end of the slide cylinder. A spring is fixedly connected between the top of the support foot and the inner wall of the top of the slide cylinder. By setting the support structure, the cleaning strip stands up when returning and sticks to the inner wall of the filter cylinder.

[0012] As a further optimization scheme of the present invention, the filtering surface of the filter cartridge is a fine metal mesh woven structure. The mesh structure is different from the conventional filtering structure. The conventional filtering structure adjusts the filtering accuracy by the pore size. However, when used for fiber slurry filtration, since the fibers are small and fluffy strips, filtering through the filter holes requires a finer pore size. Therefore, a fine mesh can be set to block the fibers in the middle without the need to set finer filter holes, thereby increasing the flow rate and preventing clogging.

[0013] The beneficial effects of the present invention are:

[0014] The present invention provides a stirring and filtering assembly, which generates centrifugal force through the spokes while stirring, so that the raw pulp is thrown out through the side wall of the filter cartridge, and then the raw pulp to be filtered is sucked into the end of the filter cartridge, and the cylinder drives the sliding plate to make reciprocating motion, and the sliding plate drives the cleaning bar to move. When the cleaning bar moves away from the cylinder, the cleaning bar drops, and when it returns, it rises. During the reciprocating motion, the tangential water flow formed by the raw pulp and the baffle are used to gather and collect the fiber clusters, and they are collected and cleaned through the collection trough, ensuring that the raw pulp is continuously and efficiently filtered without stopping the machine.

[0022] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1-6As shown, a fiber pulp stirring device for fabric production includes a pulp pool 1, a stirring and filtering component 2 and a cleaning structure 3. The stirring and filtering component 2 includes a filter cartridge 22 arranged at the bottom end of the pulp pool 1 and driven to rotate by a motor 24. The outer surface of the filter cartridge 22 is provided with a spoke plate 23 for centrifugation. The cleaning structure 3 includes a fixed arm 31 arranged on the side wall of the pulp pool 1 and extending into the filter cartridge 22. The fixed arm 31 has a U-shaped cross-section, and a sliding plate 32 driven by a cylinder 37 is slidingly provided inside the fixed arm 31. The surface of the sliding plate 32 is provided with at least two one-way hinges 35 along the sliding direction. The one-way hinges 35 are all hinged to a cleaning strip 33 through a hinge rod 36. The outer surface of the cleaning strip 33 is provided with an elastic cleaning head 34 that contacts the inner wall of the filter cartridge 22.

[0025] The interior of the stock pool 1 is divided into two upper and lower areas by a mesh 101. The upper end is a sizing pool 102, and the lower end is a stirring pool 103. The stirring area and the sizing area are separated by the mesh 101 to prevent the stirring process from affecting the warp yarn.

[0026] The filter cartridge 22 is rotatably arranged at the bottom end of the raw pulp pool 1 through a large bearing part 21, and the motor 24 is arranged outside the raw pulp pool 1, and the power is transmitted through the rotating shaft and gears. The outer wall of the filter cartridge 22 is provided with a gear ring corresponding to the gear. By setting up the motor 24 to drive, the filter cartridge 22 can rotate at high speed, and generate centrifugal force through the spoke plate 23 to throw out the raw pulp, so that the raw pulp passes through the side wall of the filter cartridge 22 and applies pressure for filtration.

[0027] The upper end of the fixed arm 31 is provided with baffles 312 along both sides of the cleaning bar 33, one side baffle 312 is in contact with the inner wall of the filter cartridge 22, and a gap is left between the other side baffle 312 and the inner wall of the filter cartridge 22. As the filter cartridge 22 rotates at a high speed, in order to collect the fibers scraped by the cleaning head 34, the movement of the fibers is restricted by setting the baffle 312 so that they remain between the two baffles 312, making it convenient for them to enter and converge through the reciprocating motion of the cleaning bar 33. After the filter cartridge 22 rotates, the cleaning head 34 scrapes off the fibers and forms a mass on the surface of the cleaning head 34. When the cleaning bar 33 descends, the cleaning bar 33 breaks away from the inner wall of the filter cartridge 22, forming a gap. However, the rotation of the filter cartridge 22 still causes the raw pulp to have tangential water flow and centrifugal water flow, which passes through the right baffle 312 (with Figure 6 The fiber clusters gathered on the surface of the cleaning bar 33 are propped up, so that the fiber clusters are rolled up under the push of the tangential water flow and blocked by the left baffle 312. Then, after the cleaning bar 33 is raised, the fiber clusters are driven to gradually converge toward the end.

[0028] A collecting trough 4 is provided on the side wall of the raw pulp pool 1. The collecting trough 4 penetrates into the interior of the raw pulp pool 1 and is connected to the fixed arm 31. The cross-section of the collecting trough 4 is a square tubular structure. The collecting trough 4 is provided to collect the gathered fiber clusters and store them. At the same time, the collecting trough 4 is provided as a cleaning window, and the normal operation of the device is not affected during cleaning.

[0029] One end of the filter cartridge 22 is close to the end of the collecting tank 4, which is used to reduce the turbulence at the connection between the collecting tank 4 and the fixed arm 31, reduce the impact of the turbulence on the fiber clusters, and make the fiber clusters converge to the end under the action of the cleaning strip 33, which is convenient for collection and cleaning.

[0030] The end of the fixed arm 31 is also provided with a support structure for supporting the cleaning strip 33. The support structure includes a slope 311 provided inside the fixed arm 31, a slide cylinder 38 provided at the lower end of the cleaning strip 33, and a support foot 310 corresponding to the slope 311 is provided at the lower end of the slide cylinder 38. A spring 39 is fixedly connected between the top of the support foot 310 and the inner wall of the top of the slide cylinder 38. By providing the support structure, the cleaning strip 33 stands up when returning and is close to the inner wall of the filter cartridge 22, wherein the support structure is provided. Figure 3 As shown in the perspective, when the sliding plate 32 moves to the right, the hinge plate 36 tilts, and the cleaning strip 33 presses on the one-way hinge 35, so that the hinge rod 36 is as shown in FIG. Figure 3 In the inclined state shown, the posture is maintained and moved to the right, and the support leg 310 contacts the slope 311 and is compressed into the slide cylinder 38. When the sliding plate 32 moves to the left, the upward thrust of the straight support leg 310 and the thrust of the upper left of the hinge rod 36 cause the cleaning bar 33 to rise and come into close contact with the filter cylinder 22. It should be noted that even if the support leg 310 structure is not provided, the sliding plate 32 can slide quickly, relying on inertia to cause the hinge rod 36 to stand up and the cleaning bar 33 to rise.

[0031] The filtering surface of the filter cartridge 22 is a fine metal mesh woven structure. The mesh structure is different from the conventional filtering structure. The conventional filtering structure adjusts the filtering accuracy by the pore size. However, when used for fiber slurry filtration, since the fibers are small, fluffy strips, filtering through the filter holes requires a finer pore size. Therefore, a fine mesh can be set to block the fibers in the middle without the need to set finer filter holes, thereby increasing the flow rate and preventing blockage.

[0032] The specific implementation method is as follows: the warp yarn passes through the sizing pool 102 for sizing, and the motor 24 drives the filter drum 22 to rotate for stirring. While stirring, centrifugal force is generated through the spoke plate 23, so that the raw pulp is thrown out through the side wall of the filter drum 22, and then the raw pulp to be filtered is sucked into the end of the filter drum 22, and the cylinder 37 drives the sliding plate 32 to do reciprocating motion, and the sliding plate 32 drives the cleaning bar 33 to move. When the cleaning bar 33 is away from the cylinder 37, the cleaning bar 33 drops and rises when returning. During the reciprocating motion, the tangential water flow formed by the raw pulp and the baffle 312 are used to gather and collect the fiber clusters, and they are collected and cleaned through the collection tank 4, ensuring that the raw pulp is continuously and efficiently filtered without stopping the machine.

[0033] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
