Abstract

The invention relates to a positive pressure filter, comprising a filter press frame, on which a clean liquid collection cavity, a dirty liquid filter cavity and a circulation filter belt are fixed, and the dirty liquid filter cavity is arranged vertically above the clean liquid collection cavity, The top of the clean liquid collection chamber is in sealing communication with the bottom of the dirty liquid filter chamber, the circulating filter belt is set between the clean liquid collection chamber and the dirty liquid filter chamber, and the top of the dirty liquid filter chamber is provided with a filter for pressing downward and lifting the dirty liquid upward. The compression and lifting device of the liquid filter cavity, the dirty liquid filter cavity is connected to the sewage tank through the first pipeline and the second pipeline, the first pipeline is equipped with a sewage lifting pump, and the second pipeline is equipped with a sewage discharge solenoid valve. The liquid collecting chamber is connected to the clean liquid water tank through the third pipeline, and a brush assembly for washing the circulating filter belt is arranged outside the clean liquid collecting chamber and on the filter press frame. The invention realizes the recycling of the filter belt, effectively controls the cleanliness of the cooling liquid, improves the filtering efficiency, and reduces the production operation cost.

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...
