Description

TECHNICAL FIELD

[0002] In the field of mechanical processing, the grinding machine is an important equipment for precision grinding of various parts. During the operation of the grinding machine, a large amount of cooling water is usually used for cooling in order to reduce the grinding temperature and prolong the service life of the grinding wheel. However, during the grinding process, the metal chips generated by grinding, the grinding wheel wear particles, and the impurities in the cooling water are mixed together, forming a sludge with certain viscosity and adhesion. The sludge mixed with cooling water is discharged outward. If direct discharge is adopted, the mixture of sludge and water will gradually block the drainage pipeline. If the filtering and reuse method is adopted, the existing filtering device cannot effectively filter the sludge, which will increase the impurity content in the next round of cooling water and affect the cooling effect. Therefore, a device capable of filtering the mixture of sludge and water is needed to ensure that water and sludge can be effectively separated. SUMMARY
