A kind of CNC machine tool coolant circulation filter

Abstract

The invention relates to the technical field of numerically controlled machine tools, in particular to a coolant circulation filter for numerically controlled machine tools, comprising a circulation filter part and a cold shower part, wherein the circulation filter part is composed of a primary filter element, a secondary filter element and a receiving tank, The circulating filter part designed in the present invention has the dual functions of filtering the used cooling liquid and facilitating the manual removal of filtering impurities. In terms of filtration, the circulating filter part adopts the method of classification filtering, that is, the circulating filter part can be filtered according to the use The types of impurities contained in the cooling liquid are classified and filtered, so as to improve the filtering effect of the cooling liquid, and it is also convenient to classify, collect and process the filtered impurities. The filter part adopts a movable assembly structure, and with the cooperation of labor, the filtering impurities can be quickly and concentratedly removed from the structure to which it is attached.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a cooling liquid circulating filter for numerical control machine tools. Background technique [0002] During the processing of the workpiece by the CNC machine tool, due to the high temperature of the processing part, it is easy to cause certain deformation of the processing structure and the workpiece. Therefore, it is necessary to spray coolant on the processing position for cooling treatment. Adhering to environmental protection, energy saving and cost reduction Under the concept, the used coolant needs to be filtered for recycling. [0003] Because wastes including iron-containing substances, non-iron substances and other impurities will be generated during workpiece processing, and in order to reduce the friction of CNC machine tool processing parts and protect CNC machine tools, lubricating oil is usually applied to the surface of CNC machine tool p...

AI Technical Summary

Problems solved by technology

[0003] Because scraps including impurities such as iron-containing substances and iron-free substances will be produced during workpiece processing, and at the same time, in order to reduce the friction of the CNC machine tool processing parts and protect the CNC machine tools, lubricating oil is usually applied to the surface of the CNC machine tool processing parts, so Waste and lubricating grease will be entrained in the recovered coolant, but there are disadvantages in the existing cooling liquid recovery and recycling process. For example, waste and lubricating grease cannot be filtered separately, and the waste can be completely removed through one filtration The effect of lubricating grease and lubricating grease is poor, and it is rarely classified and filtered according to the type of impurities contained in the waste; the filtered waste and lubricating grease accumulate on the filter structure and are not easy to be quickly removed and collected. In the case of a lot of waste and lubricating grease, the filtering effect of the filter structure will be greatly reduced
