Abstract

The invention relates to a positive pressure filter including a filter pressing frame; the filter pressing frame is fixedly provided with a clear liquid collecting cavity, a waste liquid filtering cavity and a circulating filter belt; the waste liquid filtering cavity is arranged at the vertical upper side of the clear liquid collecting cavity; the top of the clear liquid collecting cavity sealedly communicates with the bottom of the waste liquid filtering cavity; the circulating filter belt is arranged between the clear liquid collecting cavity and the waste liquid filtering cavity; the top of the waste liquid filtering cavity is provided with a pressing lifting device used for pressing downwards and lifting upwards the waste liquid filtering cavity; the waste liquid filtering cavity communicates with a waste liquid tank through a first pipeline and a second pipeline, the first pipeline is provided with a waste liquid lifting pump, and the second pipeline is provided with a waste liquid discharge electromagnetic valve; the clear liquid collecting cavity communicates with a clear liquid tank through a third pipeline; a hairbrush assembly for cleaning and brushing the circulating filter belt is arranged outside the clear liquid collecting cavity and on the filter pressing frame. Circulating use of the filter belt is realized, the cleanliness of a cooling liquid is effectively controlled, the filtering efficiency is improved and the production operation cost is reduced.

Description

technical field [0001] The invention relates to the filtration of impurities such as metal particles and grinding dust produced in the grinding process, and to a filtering device for cooling and lubricating fluid that can be widely used in high-precision machining processes such as steel rolling, grinding, and honing. A positive pressure filter. Background technique [0002] During the metal grinding process, a large amount of impurities such as metal particles and grinding dust will be produced. Due to the high speed of grinding and cutting, a large amount of heat will be generated during the grinding process, which will cause burns, deformation, cracks, etc. of the workpiece. Spray the coolant to cool down, so the metal particles and grinding dust generated during the grinding process will enter the coolant. After the coolant has been used for a certain period of time, a large amount of metal particles and other sundries will be deposited in the tank where the coolant is...
