Description

Technical Field

[0001] This utility model relates to the field of textile auxiliary production technology, and in particular to a stirring blade structure for textile auxiliary production with anti-caking function. Background Technology

[0002] In the production of textile auxiliaries, stirring is a crucial step to ensure uniform mixing and sufficient reaction of materials. Textile auxiliaries are mostly multi-component mixtures containing polymers, surfactants, functional powders, and other ingredients. During stirring, these materials are prone to clumping due to uneven dispersion, excessively high local concentrations, or dead zones, which not only affects the performance stability of the auxiliaries but also clogs subsequent production equipment, reducing production efficiency. Therefore, developing a stirring blade structure with anti-caking capabilities for textile auxiliary production is of great significance for improving the quality of textile auxiliary products and ensuring continuous production.

[0003] In existing technologies, the mixing blades commonly used in textile auxiliary agent production are mostly traditional straight blades, turbine blades, or anchor blades. Their technical principle is mainly based on the rotation of the blades driving the material in a circular motion, utilizing the shear force and thrust between the blades and the material to achieve mixing. Specifically, straight blades rely on the plane of the blades to push the material, forming a combined axial and radial flow; turbine blades generate strong radial flow through high-speed rotation, enhancing radial mixing of the material; and anchor blades are designed to fit against the vessel wall, primarily used to scrape off material adhering to the vessel wall, reducing scaling. All these structures achieve material mixing through a single mechanical stirring method, relying on the overall movement of the blades.

[0004] However, existing mixing impellers generally suffer from weakened central flow fields. Because the edge linear velocity is much higher than the central region during impeller rotation, material flow in the central region is slow, easily forming dead zones. This causes material in these areas to clump and deposit due to prolonged retention, and even broken small clumps re-agglomerate in the central region, severely affecting the mixing uniformity of textile auxiliaries and failing to meet high-quality production requirements. Therefore, a mixing impeller structure with anti-caking function for textile auxiliary production is proposed to solve these problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a stirring blade structure for textile auxiliary production with anti-caking function, aiming to improve the problems of agglomeration and secondary aggregation caused by weakened central flow field and incomplete crushing in the existing stirring blade.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A stirring blade, comprising a rotating shaft sleeve and a blade body, is used for stirring textile auxiliaries.

[0012] The shearing blade has its sidewall slidably connected inside the mounting rib, which provides a mounting position for the shearing blade. The shearing blade treats the clumps formed by the tearing blade, which can break up the clumps while avoiding excessive shearing damage to the textile auxiliaries.

[0013] Micro-barbs are used to thoroughly disperse materials and prevent the reformation of agglomerates.

[0014] As a further description of the above technical solution:

[0015] A connecting sleeve is fixedly connected to the inner wall of the rotating shaft sleeve, and the side wall of the connecting sleeve is provided with spiral ridges, which are used to push the material to flow axially through the spiral ridges.

[0019] The shearing blade is made of comb-shaped elastic steel sheets, and the direction of the shearing blade edge is opposite to the rotation direction of the blade body, and is tilted backward at 45°.

[0020] As a further description of the above technical solution:

[0021] The micro-barbs and shearing blades are distributed alternately, and the micro-barbs are conical in shape and arranged in a straight line along the rotational tangent of the blade body.

Combined with the tearing blade, shearing blade, and micro-thorn blade, it performs gradient crushing and deep dispersion of lumps of different sizes, enabling the textile auxiliary agent to achieve full-dimensional dispersion from large pieces to micro-particles during the stirring process. This achieves a highly efficient anti-caking effect and solves the problem of agglomeration and secondary aggregation caused by the weakening of the central flow field and incomplete crushing in existing stirring blades. The above structure improves the uniformity of textile auxiliary agent stirring and production quality. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-5 This utility model provides an embodiment of a stirring impeller structure for textile auxiliary production with anti-caking function, comprising: a stirring impeller, which includes a rotating shaft sleeve 1 and an impeller body 2, used for all-round stirring of textile auxiliary materials, so that the materials form a circulating flow field in the stirring tank, providing a basic flow field environment for subsequent crushing and dispersion; a mounting rib 6, the sidewall of which is fixedly connected to the sidewall of the rotating shaft sleeve 1, the mounting rib 6 serving to enhance the connection strength between the impeller body 2 and the rotating shaft sleeve 1; and a shearing assembly, which includes a tearing blade 5, a shearing blade 7, and a micro-barb blade 8, composed of a three-stage crushing structure, achieving the effect of gradient treatment of agglomerates of different sizes. The tearing blade 5... Blade 5 is fixedly connected to the side wall of blade body 2. Tear blade 5 is used to tear and break larger lumps. The impact force generated by high-speed rotation tears the lumps from the inside, achieving the initial decomposition of large materials. Shear blade 7 is slidably connected to the inside of mounting rib 6. Mounting rib 6 provides a stable mounting position for shear blade 7 and limits the swing range of shear blade 7. Shear blade 7 processes the lumps after being broken by tear blade 5, and can avoid excessive shearing damage to sensitive components in textile auxiliaries while breaking up the lumps. Micro-barb blade 8 is used to thoroughly disperse materials. By piercing into the interior of small lumps, it destroys their agglomeration structure and prevents the reformation of lumps.

[0037] A connecting sleeve 3 is fixedly connected to the inner wall of the rotating shaft sleeve 1. The connecting sleeve 3 has a spiral ridge 4 on its side wall. The spiral ridge 4 has a pitch of 15mm and a height of 3mm. It is used to push the material in the central area to flow axially through the spiral ridge 4, and in conjunction with the rotational motion of the blade body 2, it breaks the stagnation of the material in the central area.

[0038] The tearing blade 5 is serrated with equilateral triangular teeth, 8mm high, and 10mm apart. The serrations of the tearing blade 5 are aligned with the rotation direction of the blade body 2 and tilted forward at 30°. Combined with the high-speed rotation of the blade body 2, it generates a strong impact force using the high linear velocity of the outer periphery, achieving efficient tearing of large clumps larger than 5mm. The shearing blade 7 is composed of comb-shaped elastic steel sheets with a thickness of 1mm and a length of 20mm. The cutting edge of the shearing blade 7 is opposite to the rotation direction of the blade body 2 and tilted backward at 45°. Combined with the sliding connection structure of the rivet 9, it can generate flexible oscillation under the action of material resistance. The micro-barb blade 8 is staggered with the shearing blade 7. The micro-barb blade 8 is conical in shape with a cone base diameter of 0.8mm and a cone height of 0.5mm. It is made of zirconia ceramic material and is arranged in a straight line along the rotation tangent of the blade body 2, enabling it to accurately penetrate into the interior of small clumps.

[0039] The mounting rib 6 has a sliding connection to the rivet 9 inside. The side wall of the rivet 9 is slidably connected to the inside of the shearing blade 7, providing a swing fulcrum for the shearing blade 7. The mounting rib 6 has a rubber pad 10 inside. The rubber pad 10 is made of nitrile rubber. The side wall of the rubber pad 10 is in contact with the side wall of the shearing blade 7 to buffer the impact force generated when the shearing blade 7 swings, reduce component wear and reduce noise.

[0040] The rotating shaft sleeve 1 drives the overall structure to rotate synchronously, and the spiral convex texture 4 of the connecting sleeve 3 promotes the flow of central material. Combined with the three-stage crushing action of tearing blade 5, shearing blade 7, and micro-thorn blade 8, a coordinated action of central guiding, peripheral tearing, middle layer shearing, and surface piercing is formed, realizing full-dimensional processing from large clumps to micro particles, and improving the mixing uniformity and anti-caking effect of textile auxiliaries.

[0041] Working principle: When the equipment is used for stirring, the external drive device drives the blade body 2 to rotate through the rotating shaft sleeve 1. During the rotation, the blade body 2 performs basic stirring of the textile auxiliary agent, forming a large-scale material flow field. The connecting sleeve 3 on the inner wall of the rotating shaft sleeve 1 and the spiral convex texture 4 on its side wall rotate synchronously, pushing the material in the central area to flow axially, avoiding agglomeration and deposition caused by the weakening of the central flow field.

[0042] The tearing blade 5, which rotates with the blade body 2, uses the high linear velocity of its outer periphery to tear and break up larger lumps of material larger than 5mm. The special angle design of the saw teeth can efficiently hook the lumps and apply shearing force, initially decomposing the large lumps into medium lumps of 1-5mm, laying the foundation for subsequent processing.

[0043] After being broken by the tearing blade 5, the medium-sized agglomerates enter the middle area of ​​the blade with the material flow and come into contact with the shearing blade 7. The shearing blade 7 is a comb-shaped elastic steel sheet, which is slidably connected to the inside of the mounting rib 6 by the rivet 9. Its cutting edge direction is opposite to the rotation direction and tilted back 45°. When the material flows through, the elastic steel sheet generates flexible oscillation due to the resistance. Utilizing the buffering effect of the rubber pad 10 inside the mounting rib 6, excessive shearing is avoided while shearing the agglomerates, and the medium-sized agglomerates are further decomposed into fine agglomerates of less than 1mm.

[0044] Fine clumps enter the center and surface area of ​​the blade with the material flow, and interact with the micro-barbs 8. The micro-barbs 8 are conical and are staggered with the shearing blades 7 and arranged along the rotation tangent. They can pierce into the agglomerated fine clumps and completely destroy the clump structure through the piercing action. The staggered distribution design ensures that there are no dead corners when the material flows through, achieving uniform dispersion at the micro level and preventing the clumps from forming again. Ultimately, this achieves efficient mixing and anti-caking effects for textile auxiliaries.
