Embodiment Construction

[0018] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] A method for reclaiming cutting fluid by ceramic membrane filtration, such as figure 1 shown, including the following steps:

[0020] (1) Collect the cutting fluid discharged from production and store it in the settling tank, separate the floating oil on the upper layer through the oil scraper, and output the floating oil to the waste oil collection barrel through the oil guide pipe;

[0021] (2) Pump the cutting fluid in the settling tank into the collection tank through the lifting pump, and then separate the floa...

Abstract

The invention discloses a method for recovering cutting fluid by ceramic membrane filtration. The method comprises the following steps: (1) preliminary oil removal treatment is performed; (2) secondary oil removal treatment is performed; (3) the cutting fluid flows through an inorganic ceramic membrane group and is filtered and purified; (4) the cutting fluid filtered by the inorganic ceramic membrane group enters a recovery liquid tank, flows through an ultraviolet lamp tube for sterilization and then is supplied to a grinding machine workshop. The cutting fluid is filtered and recovered withan inorganic ceramic membrane technology and can be purified and recovered, pollutant oil, bacteria and impurities in the cutting fluid are removed, and main raw materials such as a surfactant, a preservative, a bactericide and the like of the cutting fluid are retained, so that the cutting fluid is effectively recycled, and the recovery efficiency is high; The method is simple and easy to operate and is suitable for large-scale operation; the recovered cutting fluid is sterilized by the ultraviolet lamp tube, bacterial contamination in the cutting fluid can be removed, and the cutting fluidis purified.

Description

technical field [0001] The invention belongs to the technical field of ceramic membrane filtration, and in particular relates to a method for recovering cutting fluid through ceramic membrane filtration. Background technique [0002] With the rapid development of modern machinery manufacturing industry, cutting fluid has been widely used in machining, and the consumption has increased rapidly. However, the cutting fluid will become invalid after a certain period of use and become industrial waste. The main reason for the failure of cutting fluid is that it is inevitably mixed with some impurities during the recycling process, such as metal particles (debris), dust, abrasive particles, fibers, free miscellaneous oil, water in cutting oil, etc. When the content of these impurities is high, it will damage the tool and the machined surface during use. Furthermore, these impurities are the main catalysts for the oxidative deterioration of the cutting fluid, and they will accele...
