A high-speed disperser for ultra-fine micro powder

Abstract

This utility model discloses an ultra-fine powder high-speed disperser, including a base, a lifting column, a crossbeam, a dispersion motor mounted on the crossbeam, a rotating shaft mounted on the other end of the crossbeam, and a dispersion tank. While the rotating shaft drives the main shaft to rotate, it also drives four driven gears to rotate via a drive gear. This causes the first and second dispersion discs to operate at different speeds within the dispersion tank, ensuring more uniform force distribution on the material during dispersion. Through the through-holes and guide plates on the first and second dispersion discs, centrifugal force is used to throw the material outwards during high-speed rotation, creating a pressure difference. According to Bernoulli's principle, the material's flow velocity increases as it passes through the through-holes, further refining the particles. Furthermore, the guide plates at the edges of the through-holes, with their inclined angle design, guide the high-speed flowing material in a specific direction, preventing localized eddy accumulation. Simultaneously, the reverse thrust generated by the guide plates enhances the stability of the material circulation path and reduces energy loss.

Description

Technical Field

[0001] This utility model relates to the field of high-speed disperser technology, specifically to a high-speed disperser for ultra-fine micro powders. Background Technology

[0002] The production process of ultrafine powder requires the use of a high-speed disperser. The lifting and lowering of the high-speed disperser can effectively stir, dissolve, and disperse many kinds of mixed liquids and solids. The main motor of the high-speed disperser is a variable speed motor, and its speed range can reach 80-1200 rpm. It can be used for stirring and dissolving at medium speed. Under the action of the blades rotating at very high speed, the material can be violently tumbled up and down in the container, resulting in strong impact and shearing between the material and the blades. This further breaks down the aggregates, effectively achieving rapid dispersion, homogeneous mixing, and accelerated dissolution.

[0003] However, the high-speed dispersers commonly available on the market often fail to meet production requirements when dispersing ultrafine powders, resulting in mediocre dispersion effects and low production efficiency. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a high-speed disperser for ultrafine powders, thus solving the aforementioned technical problems.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a high-speed disperser for ultra-fine micro powder, comprising a base, a lifting column, a crossbeam, a dispersion motor mounted on the crossbeam, a rotating shaft mounted on the other end of the crossbeam, and a dispersion tank. A hydraulic cylinder is installed inside the lifting column, and the crossbeam is mounted on the output end of the hydraulic cylinder. A connecting rod extends downward from the bottom of the crossbeam, and a mounting plate is detachably connected to the connecting rod. A transmission cavity is opened in the mounting plate, and a drive gear is rotatably mounted at the center of the transmission cavity. Four driven gears meshing with the drive gear are rotatably mounted in the transmission cavity. The rotating shaft is detachably connected to the drive gear. A main shaft and a secondary shaft, respectively, are provided at the bottom of the drive gear and the driven gear, penetrating the transmission cavity and extending to the outside. A first dispersion disc and a second dispersion disc are respectively installed at the bottom of the main shaft and the secondary shaft. Multiple inclined blades are arranged on both the first and second dispersion discs. Multiple through holes are opened along the circumferential direction on both the first and second dispersion discs. An inclined guide plate is provided at the opening of the through hole. An ultrasonic vibrating rod is bolted to the bottom of the mounting plate.

[0006] Preferably, the guide plates at the multiple through-hole openings on the same first or second dispersion disk are spaced apart at the top and bottom of the dispersion disk.

[0007] Preferably, the length of the main shaft is greater than the length of the secondary shaft.

[0008] Preferably, the top of the drive gear is provided with a mating block that penetrates the mounting plate and extends to the outside, and the bottom of the rotating shaft is provided with a mating groove that matches the mating block. The mating block is fixed in the mating groove by bolts.

[0009] Preferably, the mounting plate has a groove that matches the connecting rod, and the connecting rod is fixed in the groove by bolts.

[0010] Preferably, the oblique blades are evenly arranged along the circumferential direction at the top and bottom of the first or second dispersion disk.

[0011] Preferably, the four driven gears are evenly distributed in the transmission cavity along the circumferential direction.

[0012] Compared with the prior art, this utility model provides an ultra-fine micro powder high-speed disperser with the following beneficial effects: Through the coordinated structure of the driving gear, driven gear, first dispersion disc, and second dispersion disc, this utility model allows the main shaft to rotate while the driving gear drives four driven gears to rotate simultaneously. This enables the first and second dispersion discs to operate at different speeds within the dispersion tank, ensuring more uniform force on the material during dispersion. Furthermore, the through holes and guide plates on the first and second dispersion discs allow centrifugal force to be used during high-speed rotation to create a pressure difference, which, according to Bernoulli's principle, accelerates the flow rate of the material through the through holes, further refining the particles. The guide plates at the edges of the through holes, designed with an inclined angle, guide the high-speed flowing material in a specific direction, preventing localized eddy accumulation. Simultaneously, the reverse thrust generated by the guide plates enhances the stability of the material circulation path and reduces energy loss. Attached Figure Description
