Purifying device for cutting fluid

Abstract

The invention discloses a purifying device for a cutting fluid. The purifying device comprises a waste fluid input pipe, a settling tank, a filtering tank and a fluid-purifying tank, wherein the settling tank is divided into a first settling cabin, a second settling cabin and a third settling cabin, the filtering tank is divided into a first filtering cabin, a second filtering cabin and a third filtering cabin, the fluid-purifying tank is divided into a first fluid-purifying cabin, a second fluid-purifying cabin and a third fluid-purifying cabin; stirring paddles are arranged in the second filtering cabin and the second fluid-purifying cabin, the waste fluid input pipe is communicated with the top of the first settling cabin, the third settling cabin is communicated with the top of the first filtering cabin through a waste fluid extraction pipe, the opening of waste fluid extraction pipe in the third settling cabin is arranged at the bottom of the third settling cabin, the waste fluid extraction pipe is provided with a first oil pump, the bottom of the third filtering cabin has an outlet, the outlet is arranged right above the first fluid-purifying cabin, the third fluid-purifying cabin is provided with a fluid-purifying output pipe, and the fluid-purifying output pipe is provided with a second oil pump. The purifying device disclosed by the invention is simple in structure, convenient to operate and capable of effectively purifying the recycled cutting fluid.

Description

technical field [0001] The invention relates to a purification device, in particular to a cutting fluid purification device. Background technique [0002] In the machining process, a large amount of cutting fluid is used for lubrication and cooling during metal cutting, cutting, grinding and other processing. Considering the cost, the cutting fluid is generally recycled, but the recycled cutting fluid contains iron filings, Dust and other impurities. The use of such recycled cutting fluid may cause workpiece wear, reduce machining accuracy, or damage the tool. If the recycled cutting fluid is not disposed of properly, it will not only cause waste, but more seriously, it will pollute the environment. Contents of the invention [0003] The object of the present invention is to provide a cutting fluid purification device, which has a simple structure and is easy to operate, and can effectively purify recovered cutting fluid. [0004] In order to achieve the above object, th...
