Description

Technical Field

[0001] This invention belongs to the field of chopped fiber technology, specifically relating to a simple device for uniformly dispersing chopped fibers and its working method. Background Technology

[0002] Currently, chopped fibers are used in various engineering fields, such as fiber-reinforced concrete. However, during packaging, transportation, and use, chopped fibers frequently clump and bundle, which seriously affects the uniformity and mechanical properties of fiber-reinforced concrete materials. At present, there is still no completely effective and widely applicable solution to the clumping and bundling problem of chopped fibers.

[0003] Chinese patent CN102350254A discloses a pneumatic stirring, dispersing, and web-forming device for clustered fibers. This invention provides a pneumatic stirring, dispersing, and web-forming device for clustered fibers. This patent is only effective for fibers with poor adhesion. However, for fibers with high adhesion that are clustered or bundled, it is difficult to achieve effective dispersion by relying solely on the pneumatic dispersion method of this patent.

[0004] Chinese patent CN114775285A discloses a method for dispersing PVA fibers in the preparation of ECC concrete. This invention only uses a first blower 62 to blow the fibers toward a screen 63, while the main function of the guide stirring wheel 64 is to guide the fibers toward the screen 6. This method has low efficiency in dispersing fibers and is difficult to achieve the purpose of efficient dispersion of agglomerated and bundled fibers. Summary of the Invention

[0005] This invention is proposed to solve the problems existing in the prior art, and its purpose is to provide a simple device for uniformly dispersing short-cut fibers and its working method.

[0006] The technical solution of the present invention is: a simple device for uniformly dispersing short-cut fibers, including an air compressor jet gun, the jet nozzle of the air compressor jet gun being connected to a round tube diameter conversion head, the other end of the round tube diameter conversion head being connected to an acrylic transparent tube, a fiber collection bag for collecting fibers being provided at the tail end of the acrylic transparent tube, a dispersion structure for dispersing short-cut fibers being provided on the inner wall of the acrylic transparent tube, and a feeding structure for feeding in undisturbed large clumps of fibers being provided on the outer wall of the acrylic transparent tube.

[0007] Furthermore, the acrylic transparent tube includes a vertically oriented uniformly dispersing section, a middle U-shaped section for transitional connection, and a tail collection section for collection.

[0008] Furthermore, the diameter conversion head of the circular tube is conical, with its small diameter section connected to the air nozzle of the air compressor's jet gun, and its large diameter section connected to the lower part of the uniform dispersion section.

[0009] Furthermore, the dispersion structure includes short dispersion nails, medium-length dispersion nails, and long dispersion nails disposed on the inner wall of the uniform dispersion section, wherein the lengths of the short dispersion nails, medium-length dispersion nails, and long dispersion nails gradually increase.

[0010] Furthermore, each of the dispersed short nails, dispersed medium-length nails, and dispersed long nails is arranged in a spiral circle within a uniformly dispersed section.

[0011] Furthermore, the feeding structure includes a fiber inlet located on the wall of the uniformly dispersed section, and a movable sealing plate is provided at the fiber inlet location.

[0012] Furthermore, the fiber collection bag has dense pores to ensure that the dispersed monofilament fibers are retained after the airflow in the acrylic transparent tube is expelled.

[0013] Furthermore, the air compressor jet gun has adjustable jet pressure, rotatable jet direction, and intermittent cyclic jet function.

[0014] A method for operating a simple device for uniformly dispersing short-cut fibers includes the following steps: A. Install the simple device for evenly dispersing short-cut fibers; B. Incorporate raw, large-clove fibers; C. Start the air compressor jet gun and adjust the jet pressure to spray the original large clumps of fiber into dispersed small clumps of fiber of different sizes; D. Start the air compressor's jet gun rotation function and intermittent circulating air blowing function, and the small clusters of fibers will gradually disperse into dispersed monofilament fibers; E. Collect the dispersed monofilament fibers through a fiber collection bag.

[0015] The beneficial effects of the present invention are as follows: This invention significantly improves the dispersion efficiency and quality of chopped fibers through an innovative rotating intermittent circulating high-pressure jet system, a dynamic dispersion system, and a hierarchical structure design. The three-dimensional spiral nail array layout inside the acrylic transparent tube, combined with the rotating intermittent circulating high-pressure jet, generates an irregular vortex airflow, keeping the fibers in a dynamic dispersion state of jetting, tumbling, and colliding, effectively preventing secondary agglomeration.

[0016] This invention employs a three-stage spiral distribution of dispersing spikes in synergy with an adjustable intermittent circulating wind field to form a multi-gradient collision dispersion mechanism: from the initial breaking of large fiber clusters by the bottom short spikes, to the secondary dissociation of medium-sized fiber clusters by the middle medium-length spikes, and finally to the fine separation of monofilament fibers by the top long spikes, achieving a gradual dispersion of fiber clusters "from coarse to fine" with high dispersion efficiency.

[0017] This invention effectively solves the technical problem of the difficulty in effectively dispersing short-cut fibers that are clumped and bundled in the current industry, and has high value for engineering promotion and application. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1 to 2 As shown, a simple device for uniformly dispersing short-cut fibers includes an air compressor jet gun 1. The jet nozzle of the air compressor jet gun 1 is connected to a round tube diameter conversion head 2. The other end of the round tube diameter conversion head 2 is connected to an acrylic transparent tube 3. A fiber collection bag 9 for collecting fibers is provided at the tail end of the acrylic transparent tube 3. A dispersion structure for dispersing short-cut fibers is provided on the inner wall of the acrylic transparent tube 3. A feeding structure for feeding in undisturbed large clumps of fibers 10 is provided on the outer wall of the acrylic transparent tube 3.

[0020] The acrylic transparent tube 3 includes a vertical uniform dispersion section, a middle U-shaped section for transitional connection, and a tail collection section for collection.

[0021] The diameter conversion head 2 of the circular tube is conical, with its small diameter section connected to the air nozzle of the air compressor jet gun 1, and its large diameter section connected to the lower part of the uniform dispersion section.

[0022] The dispersion structure includes short dispersion nails 6, medium-length dispersion nails 7, and long dispersion nails 8 disposed on the inner wall of the uniform dispersion section, wherein the lengths of the short dispersion nails 6, medium-length dispersion nails 7, and long dispersion nails 8 gradually increase.

[0023] The dispersed short nails 6, dispersed medium-length nails 7, and dispersed long nails 8 are each arranged in a spiral circle within a uniformly dispersed section.

[0024] The feeding structure includes a fiber inlet 4 located on the wall of the uniformly dispersed section, and a movable sealing plate 5 is provided at the fiber inlet 4.

[0025] The fiber collection bag 9 has dense pores to ensure that the dispersed monofilament fibers 12 are retained after the wind in the acrylic transparent tube 3 is removed.

[0026] The air compressor jet gun 1 has adjustable jet pressure, rotatable jet direction, and intermittent cyclic jet function.

[0027] Specifically, the round tube diameter conversion head 2 achieves a sealed connection between large and small diameters, used for the sealed connection between the air compressor jet gun 1 and the acrylic transparent tube 3. At the same time, its internal conical cavity can accommodate the original large clump of fibers 10. The round tube diameter conversion head 2 is made of rubber, and the rubber material satisfies the purpose of allowing the air compressor jet gun 1 to rotate in the jet direction.

[0028] Specifically, the acrylic transparent tube 3 is made of transparent material, allowing for real-time observation of the movement and dispersion of its internal fibers. Its uniform dispersion section, middle U-shaped section, and tail collection section are integrated into one structure.

[0029] Specifically, a fiber inlet 4 is provided on one side of the lower part of the acrylic transparent tube 3. The fiber inlet 4 is used for the input of raw large clumps of fiber 10. The movable sealing plate 5 is installed on the acrylic transparent tube 3. When it is opened, the raw large clumps of fiber 10 can be input into the fiber inlet 4. When it is closed, it can ensure that the fiber inlet 4 is in a sealed state.

[0030] Specifically, the dispersed short nails 6, dispersed medium-long nails 7, and dispersed long nails 8 are arranged spirally from bottom to top.

[0031] A method for operating a simple device for uniformly dispersing short-cut fibers includes the following steps: A. Install the simple device for evenly dispersing short-cut fibers; B. Add 10g of unprocessed large-clove fiber; C. Start the air compressor jet gun 1 and adjust the jet pressure to spray the original large clump of fibers 10 into dispersed small clumps of fibers 11 of different sizes; D. Start the rotation function and intermittent circulating air blowing function of the air compressor jet gun 1, and the dispersed small clumps of fiber 11 are gradually dispersed into dispersed monofilament fibers 12. E. Collect the dispersed monofilament fibers 12 through the fiber collection bag 9.

[0032] Specifically, step B involves adding 10 undisturbed large clumps of fiber, and the specific process is as follows: b1. Open the movable sealing plate 5 and put the original large clump of fiber 10 into the fiber inlet 4; b2. Close the movable sealing plate 5 to ensure the fiber inlet 4 is sealed; b3. The original large clump of fibers 10 will remain within the diameter conversion head 2 of the round tube under its own weight.

[0033] Specifically, in step C, the air compressor's jet gun 1 is activated and the jet pressure is adjusted to spray the original large clumps of fibers 10 into dispersed small clumps of fibers 11 of different sizes. The specific process is as follows: c1. Start the air compressor jet gun 1 and adjust it to a suitable jet pressure so that the original large clump of fibers 10 is sprayed into dispersed small clumps of fibers 11 of different sizes; c2. At the same time, ensure that the dispersed small fiber clusters 11 do not cross the bend of the acrylic transparent tube 3 under the set air pressure.

[0034] Specifically, in step D, the air compressor's jet gun 1 is activated, and its intermittent circulating air blowing function is started. After dispersion, the small clumps of fibers 11 are gradually dispersed into dispersed monofilament fibers 12. The specific process is as follows: d1. Start the rotation function and intermittent circulating air blowing function of the air compressor jet gun 1. At this time, the dispersed small fiber clumps 11 move in an irregular spiral and up-and-down rolling motion in the acrylic transparent tube 3 under the action of jet pressure. d2. The short dispersed spikes 6, medium dispersed spikes 7, and long dispersed spikes 8 on the inner wall of the acrylic transparent tube 3 are also arranged in a spiral circle. This arrangement makes it easier for the small clusters of fibers 11 to collide with and further disperse after dispersion. d3. On the other hand, from bottom to top, the gradual increase in the length of the dispersing nails makes the size of the dispersed small fiber clusters 11 gradually smaller. At the same time, the spiral arrangement of the dispersing nails can prevent the dispersed fibers from accumulating and clogging in the acrylic transparent tube 3. d4. After the action of dispersing short spikes 6, dispersing medium long spikes 7, and dispersing long spikes 8, the dispersed small clusters of fibers 11 are dispersed into dispersed monofilament fibers 12.

[0035] Specifically, in step E, the dispersed monofilament fibers 12 are collected through the fiber collection bag 9. The specific process is as follows: When the dispersed small clumps of fiber 11 become dispersed monofilament fibers 12, the dispersed monofilament fibers 12 are relatively light in weight and can pass through the bend of the acrylic transparent tube 3 and enter the fiber collection bag 9 under the spray pressure set by the air compressor air gun 1.

[0036] Specifically, the original large clump of fibers 10 is the fiber state before dispersion in this invention, the small clump of fibers 11 after dispersion is the fiber state during the dispersion process in this invention, and the single filament fiber 12 after dispersion is the fiber state after final dispersion in this invention.

[0037] This invention significantly improves the dispersion efficiency and quality of chopped fibers through an innovative rotating intermittent circulating high-pressure jet system, a dynamic dispersion system, and a hierarchical structure design. The three-dimensional spiral nail array layout inside the acrylic transparent tube, combined with the rotating intermittent circulating high-pressure jet, generates an irregular vortex airflow, keeping the fibers in a dynamic dispersion state of jetting, tumbling, and colliding, effectively preventing secondary agglomeration.

[0038] This invention employs a three-stage spiral distribution of dispersing spikes in synergy with an adjustable intermittent circulating wind field to form a multi-gradient collision dispersion mechanism: from the initial breaking of large fiber clusters by the bottom short spikes, to the secondary dissociation of medium-sized fiber clusters by the middle medium-length spikes, and finally to the fine separation of monofilament fibers by the top long spikes, achieving a gradual dispersion of fiber clusters "from coarse to fine" with high dispersion efficiency.

[0039] This invention effectively solves the technical problem of the difficulty in effectively dispersing short-cut fibers that are clumped and bundled in the current industry, and has high value for engineering promotion and application.
