Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a powder dispensing and dispersing device for a joint adhesive mixing tank. Background Technology

[0002] As a commonly used raw material mixing equipment, especially in the mixing and preparation of solutions and powders, the mixing tank uses agitator blades to drive the flow of the solution to mix or dissolve the powder in the solution. However, when raw materials such as powders are put into the solution, the powders tend to float on the surface of the solution and rotate with the solution, or clump together, affecting the mixing efficiency. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a powder dispensing and dispersing device for a joint adhesive mixing tank.

[0004] This utility model includes a discharge pipe and a dispersing plate installed on the feed inlet of a mixing tank. The dispersing plate has a fan-shaped structure, and a discharge pipe clearance hole is provided at the apex of the fan-shaped structure. The two ends of the discharge pipe clearance hole are rotatably installed on the discharge pipe through pins. A set of dispersing elongated holes are distributed in a fan shape on the dispersing plate.

[0005] The dispersion plate at the end furthest from the apex has a downwardly sloping bend, and the bend has a hole that communicates with the dispersion elongated hole.

[0006] The spacing between the dispersed elongated holes decreases sequentially from the inner wall of the tank towards the axis.

[0007] Both the dispersing plate and the bending section are double-layer hollow plates, and the bending section and the dispersing plate are integrally injection molded.

[0008] Dispersion plate limiting pins are provided on both sides of the feed pipe located below the dispersing plate.

[0009] A limit spring is installed on the feed pipe located above the dispersing plate.

[0010] The feed pipe is assembled from an upper pipe section located outside the mixing tank and a lower pipe section located inside the mixing tank. The diameter of the upper pipe section is smaller than that of the lower pipe section, and the dispersion plate is installed on the lower pipe section.

[0011] The advantages of this invention are: after the powder is put into the tank, as the solvent flows, the dispersing plate can quickly disperse the powder floating above the solvent, thereby improving the mixing efficiency. Attached Figure Description

[0018] As shown in the attached figure, the present invention includes a discharge pipe 10 and a dispersing plate 11 installed on the feed inlet of the mixing tank 1. The dispersing plate 11 has a fan-shaped structure and a discharge pipe clearance hole is provided at the apex of the fan-shaped structure. The two ends of the discharge pipe clearance hole are rotatably installed on the discharge pipe 10 by means of pins. A set of dispersing elongated holes 17 are distributed in a fan shape on the dispersing plate 11.

[0019] The mixing tank 1 of this case includes a tank body, and a first stirring shaft 2 and a set of second stirring shafts 3 are respectively provided in the tank body. The first stirring shaft 2 is provided with a set of scrapers 5 that are in contact with the inner wall of the tank body. The second stirring shaft 3 is provided with a spiral stirring rod 6. The set of second stirring shafts 3 is arranged in a ring around the first stirring shaft 2 and drives the first stirring shaft 2. The top of the tank body is provided with a drive motor 7 that drives the first stirring shaft 2 to rotate.

[0020] Both the second stirring shaft 3 and the first stirring shaft 2 are connected by belt drive, and the diameter of the pulley on the first stirring shaft 2 is larger than the diameter of the pulley on the second stirring shaft 3. The drive motor 7 drives the first stirring shaft 2 to rotate via the belt.

[0021] The first stirring shaft 2 is provided with a support sleeve 13, and a set of support rods 14 corresponding to the second stirring shaft 3 are provided on the support sleeve 13. The bottom end of the second stirring shaft 3 is movably connected to the support rods 14.

[0022] In this case, there are three second stirring shafts 3, and the feed pipe 10 is located between two adjacent second stirring shafts 3. During the stirring process, when the agent flows in the tank, part of the dispersing plate 11 extends into the solvent. When the powder is added from the feed pipe, the dispersing plate 11 disperses the floating powder, improving the mixing efficiency. In this case, a gap is provided between the dispersing plate 11 and the inner wall of the tank for the scraper 5 to pass through, to avoid collision.

[0023] When the first stirring shaft 2 rotates, it scrapes the mixture adhering to the inner wall of the tank through the scraper 5, and at the same time, it can drive the solvent in the tank to rotate. The second stirring shaft 3 drives the spiral stirring rod 6 to rotate in place, stirring the solvent that passes through it evenly, and at the same time, it makes the solvent flow up and down. The three second stirring shafts 3 and the first stirring shaft 2 rotate in the same direction. The solvent around each spiral stirring rod 6 forms a relatively independent stirring vortex, and the solvent between two adjacent stirring vortices will collide and further accelerate the mixing.

[0024] In this case, the direction of the dispersing plate 11 is the same as the rotation direction of the stirring shaft. The dispersing plate 11 is rotatably mounted on the feed pipe 10 by a pin and can swing up and down on the feed pipe 10 with the flow of liquid.

[0025] Furthermore, the dispersion plate 11 at the end away from the apex is provided with a downwardly inclined bend 18, and a hole communicating with the dispersion elongated hole 17 is opened on the bend 18.

[0026] The dispersing plate 11 is coaxially arranged with the feed pipe 10. The entire dispersing plate 11 has a rake tooth structure, which is used to disperse the powder floating above the solvent.

[0027] Furthermore, the spacing of the dispersed elongated holes 17 decreases sequentially from the inner wall of the tank towards the axis.

[0028] Floating powder tends to gather in the middle of the annular flowing liquid surface. In this case, the spacing of the dispersing elongated holes 17 gradually decreases from the barrel wall towards the axis, meaning that the dispersing elongated holes 17 are more dense near the axis, which can effectively disperse the powder gathered in the middle more evenly.

[0029] Preferably, both the dispersing plate 11 and the bending portion 18 are double-layer hollow plates, and the bending portion 18 and the dispersing plate 11 are integrally injection molded.

[0030] The hollow structure gives the dispersing plate 11 a certain buoyancy, allowing it to float more smoothly up and down following the flow of the liquid surface, thereby dispersing the powder that passes through.

[0031] Furthermore, a dispersing plate limiting pin 12 is provided on both sides of the feed pipe 10 located below the dispersing plate 11.

[0032] The maximum downward swing angle of the dispersion plate 11 can be limited. The dispersion plate limiting pin is located below the dispersion plate 11. In this case, the maximum downward swing angle of the dispersion plate 11 is limited to no more than 45°.

[0033] Furthermore, a limiting spring 19 is provided on the feed pipe 10 located above the dispersing plate 11.

[0034] The maximum upward swing angle of the dispersing plate 11 is limited. When the dispersing plate 11 is driven by the solvent, it swings up and down with the fluctuation of the liquid surface. When it swings upward and touches the limiting spring 19, it is blocked. Under the reaction force of the limiting spring 19, the dispersing plate 11 is pressed downward. In this case, the solvent level is less than the height of the dispersing plate 11 installation part. The optimal solvent level is two-thirds of the height of the dispersing plate 11 after it hangs down.

[0035] Furthermore, the feed pipe 10 is assembled from an upper pipe section located outside the mixing tank 1 and a lower pipe section located inside the mixing tank 1. The diameter of the upper pipe section is smaller than the diameter of the lower pipe section, and the dispersion plate 11 is installed on the lower pipe section.

[0036] Since the lower tube section is located inside the mixing tank 1, solvent splashed during the mixing process adheres to the lower tube section. The diameter of the upper tube section is smaller than that of the lower tube section. Therefore, when the powder enters from the upper tube section, it will not touch the inner wall of the lower tube section during the falling process, which can effectively prevent the powder from adhering to the lower tube section.
