Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of insulating paint production, specifically to a kind of insulating paint production grinding device. BACKGROUND

[0002] Insulating paint is a kind of functional paint that prevents current from passing by forming an insulating layer on the surface, and is widely used in electrical equipment, electronic devices and building materials to provide electrical insulation protection, wear resistance and corrosion resistance. During the production of insulating paint, grinding is a key step that directly affects the uniformity of the paint and the final insulation performance. In order to achieve the desired fineness of the particles in the paint, a special grinding device is needed to crush and disperse the material.

[0003] The patent with publication number CN208390140U discloses a vertical grinder for producing water-based silicon steel insulating paint, which includes a grinding motor and a grinding cylinder. The grinding motor is connected to a rotating shaft, and the lower end of the rotating shaft extends into the grinding cylinder. The extended part is sequentially fixed with a grinding disc, a filter assembly and a grinding block from top to bottom. The grinding disc includes a mounting part and a grinding part connected to the mounting part. The filter assembly is composed of a bearing mounted on the rotating shaft, a filter seat mounted on the outer side of the bearing and a filter partition plate mounted on the filter seat. The vertical grinder for producing water-based silicon steel insulating paint is convenient to use, significantly improves the grinding, dispersion and mixing effect, and the ground material is discharged from the discharge port in time, effectively avoiding the phenomenon of clumping and aggregation.

[0004] Although the above-mentioned grinding device improves the grinding, dispersion and mixing effect of the paint to some extent, it still has some defects that need to be solved. Specifically, the device relies on the grinding disc to preliminarily grind the material put into the grinding cylinder, and then uses the filter assembly to screen the material. Small particles of material can pass through the filter partition plate to the next step of fine grinding. However, in actual use, larger particles of material tend to gradually accumulate on the surface of the filter assembly. These particles cannot pass through the filter assembly to the grinding block for further crushing, nor can they return to the grinding disc for regrinding, resulting in gradual clogging of the filter assembly, which can cause the grinding process to be discontinuous, affecting production efficiency. Therefore, we propose a grinding device for insulating paint production. UTILITY MODEL CONTENTS
