Cutting liquid purifying treatment device

Abstract

The invention provides a cutting liquid purifying treatment device. Cutting liquid firstly is filtered through a net filtering device for the first time, large impurities are removed, then the cutting liquid enters a gravitational separation device and is finely filtered through a fine filtering screen for the second time, and waste oil is removed. Then the cutting liquid enters an impurity precipitation device and flows downwards layer by layer in a curve mode, the contact area and adsorption time are guaranteed, micro impurities are adsorbed layer by layer, and the size, the number of layers and the like of separation plates can be designed according to the quantity of the micro impurities till all the micro impurities are adsorbed. Then the cutting liquid enters a deodorization device through a fourth oil outlet for deodorization and is finally purified, and therefore the cutting liquid can be reused. Therefore, the cutting liquid purifying treatment device clears away the large impurities, the micro impurities, the waste oil and the like efficiently and thoroughly, the deodorization effect is remarkable, and the purified cutting liquid is as clean as new cutting liquid, safe, reliable and environmentally friendly, saves energy, can be completely reused or used repeatedly, and is novel and reasonable in structure, low in cost and high in practicality.

Description

technical field [0001] The invention relates to the field of liquid purification equipment, in particular to a cutting fluid purification treatment device. Background technique [0002] With the rapid development of the machinery manufacturing industry and the emergence of various new and complex workpieces, the requirements for machining accuracy and cutting fluid of machine tools are getting higher and higher. In order to save costs and protect the environment, cutting fluid needs to be recycled and maintain extremely high purity , The treatment of cutting fluid requires special filtration, deodorization and purification equipment. For example, the Chinese invention patent CN201410757159.8 discloses a cutting fluid purification device, which includes a metal filter tank, an infiltration filter tank and a static device. The tank wall of the metal filter tank is a double-layer tank wall, and a magnet layer is arranged inside the double-layer tank wall. The inner wall of the...
