Description

Technical Field

[0001] The utility model belongs to the technical field of pulverizing equipment, in particular to a colloid mill with a cooling component. Background Art

[0002] The colloid mill is first of all a centrifugal grinding and crushing equipment with a simple structure and easy equipment maintenance. It is suitable for grinding and emulsifying materials with higher viscosity and larger particles. Among them, all the parts in the colloid mill that come into contact with the material are made of high-strength stainless steel, which has good corrosion resistance and wear resistance, making the processed materials pollution-free, hygienic and pure.

[0003] The working principle of the colloid mill is to use an electric motor through a belt drive to drive the moving grinding disc and the matching fixed grinding disc to rotate relative to each other at a high speed. The processed material passes through the gap between the moving grinding disc and the fixed grinding disc under the action of its own gravity, and is simultaneously subjected to strong shear force, friction force, high-frequency vibration, high-speed vortex and other physical effects, so that the material is effectively emulsified, dispersed, homogenized and crushed, achieving the effect of ultra-fine crushing and emulsification of the material.

[0004] In the actual working process, it is found that the above-mentioned colloid mill has certain defects: first, due to the high-speed friction between the dynamic and static grinding discs, a large amount of heat is easily generated, causing the material to denature. The traditional cooling method is through the cooling water pipe wrapped around the grinding table, and the cooling effect is general; in addition, the above-mentioned colloid mill is often relatively short. When it is placed on the ground for use, the height of its discharge port is not high, so the size of the loading bucket placed under the discharge port cannot be too large, that is, the height of the loading bucket cannot be higher than the discharge port, but the volume of the loading bucket with a low height is generally not large. In order to collect all the materials discharged by the colloid mill, multiple loading buckets are required. Therefore, the staff needs to replace the loading buckets back and forth. The operation process is time-consuming and labor-intensive, and reduces the working efficiency of the colloid mill. Utility Model Content

[0005] The utility model provides a colloid mill with a cooling component with a reasonable structural design to solve the technical problems existing in the known technology. The utility model can cool the dynamic and static grinding discs, and has a good cooling effect, avoiding the heat generated by friction from causing the material to be denatured. At the same time, the height of the discharge port of the colloid mill can be adjusted according to actual work needs, and with a large-capacity loading bucket, a large amount of colloid mill discharge material can be contained at one time, thereby improving work efficiency.

[0006] The utility model adopts the following technical solutions to solve the technical problems existing in the known technologies: a colloid mill with a cooling assembly comprises a lifting drive device with multiple sets of casters installed at the bottom, a base box is installed on the lifting drive device through multiple sets of shock absorbers, a supporting rotating sleeve is installed on the base box, a mounting shell is installed on the top of the supporting rotating sleeve, and a feed hopper is installed on the top of the mounting shell; a discharge port is opened at the lower part of the mounting shell, and a circulating discharge structure is installed on the discharge port; a static grinding disc is adjustably installed in the inner cavity of the mounting shell, and a through-hole connected to the supporting rotating sleeve for rotation is also included.

[0007] The advantages and positive effects of the utility model are as follows: the utility model provides a colloid mill with a cooling assembly, which can crush and finely grind materials that fall between the moving grinding disc assembly and the static grinding disc assembly by setting a clearance fit and relatively rotatable, and can adjust the clearance between the moving grinding disc assembly and the static grinding disc assembly by setting an adjustment installation assembly to improve the grinding accuracy; by opening a lower cooling cavity structure in the moving grinding disc assembly and installing a rotating joint, the moving grinding disc assembly can be circulated with water to take away the heat on the moving grinding disc assembly, thereby avoiding heat accumulation and facilitating rapid heat dissipation; by An upper cooling chamber is opened in the static grinding disc and is equipped with a water inlet and a water outlet, so that the static grinding disc can be circulated with water to avoid heat accumulation on the static grinding disc. Through the above arrangement, the heat generated by friction can be prevented from denaturing the material, and the cooling effect is good. By arranging a lifting drive device, the discharge port of the circulating discharge structure connected to the discharge port can be adjusted, so that a large-capacity loading bucket can be placed under the discharge port of the circulating discharge structure, and then the material discharged from the colloid mill can be loaded at one time, without the need for staff to frequently change the loading container.
