AI Technical Summary

Technical Problem

The filter screen at the inlet end of the existing machine tool cooling pump needs to be disassembled and cleaned periodically, affecting the continuous operation of the machine tool equipment.

Method used

A machine cooling pump with an anti-blocking structure is designed. Through the guide cylinder, filter cylinder and centrifugal impeller integrated in the pump housing, the coolant is centrifugal filtered by the negative pressure generated by the rotation of the centrifugal impeller, and the inner wall of the filter cylinder is scraped and cleaned with a spiral scraper, and debris trapped in the annular cavity formed by the guide cylinder and the filter cylinder are collected in a centralized manner.

Benefits of technology

The disassembly and cleaning of the cooling pump filter cartridge is realized, filtration efficiency is improved, debris accumulates on the inner surface of the filter cartridge, and long-term filtration efficiency is maintained. By actively collecting debris, the integration and maintenance convenience of the machine tool cooling pump is improved.

Abstract

The invention relates to the field of pump body equipment, in particular to a machine tool cooling pump with an anti-blocking structure, which is characterized in that a guide cylinder, a filter cylinder and a centrifugal impeller are integrated in a pump shell, negative pressure generated by rotation of the centrifugal impeller is used for carrying out negative pressure centrifugal filtration on cooling liquid, and the filtering efficiency is improved; chippings in the cooling liquid are intercepted in an annular cavity defined by the guide cylinder and the filter cylinder, and the inner wall of the filter cylinder is scraped and cleaned in cooperation with a spiral scraper, so that accumulation of the chippings on the inner surface of the filter cylinder is reduced; besides, through an annular cylinder which is fixed to the outer side of the end cover and communicates with the annular cavity, chippings intercepted in the annular cavity are injected into the annular cylinder under the pushing action of a spiral scraper blade to be collected in a centralized mode, active collection of the chippings is achieved, a filter cylinder does not need to be disassembled and cleaned, and the integration level and maintenance convenience of the machine tool cooling pump are improved; in addition, the filtering holes are dredged through dredging mechanisms arranged in the filtering holes, and the filtering efficiency of the filtering cylinder is maintained.
