Modular constant-temperature multi-filter cylinder oil mist purifying and deslagging filtration system

Abstract

The invention discloses a modular constant-temperature multi-filter cylinder oil mist purifying and deslagging filtration system, comprising an integrated dirty oil collection unit, two or more dirty oil filter units capable of simultaneously and / or alternately running, a backwash mechanism for backwashing filter elements in the dirty oil filter units by turns, a sludge filter unit for carrying out secondary filter on the sludge discharged from the dirty oil filter units, a temperature control unit for cooling and / or heating the clean oil output from the dirty oil filter units and sludge filter unit, and an oil tank for collecting the clean oil processed by the temperature control unit, and the like. The invention has the advantages of compact structure, small volume, easy assembly and maintenance, and low cost, can realize thermostatic control of the temperature of the cutting fluid, guarantees the processing precision, avoids the problems of back flow due to accumulation of dirty oil, oil temperature variation and the like in the backwashing process of the filter devices, can discharge slag conveniently and rapidly, can effectively realize the recycling of resource, energy conservation and environmental protection, and can increase the additional value of the products.

Description

technical field [0001] The invention relates to a cutting fluid recovery device in the mechanical field, in particular to a modular constant temperature multi-filter barrel oil mist purification and slag discharge filtration system. Background technique [0002] In the process of machining, especially in the process of grinding, cutting and cutting metal, it is usually necessary to continuously use cutting fluid to cool and lubricate the tool and workpiece. In order to reduce production costs, the industry generally adopts the method of recycling cutting fluid, but the used cutting fluid usually contains metal dust and other solid particle impurities. For this reason, most of the traditional processes use equipment such as filter barrels installed on the machine tool to filter and remove the slag from the cutting fluid before using it. However, this method has many shortcomings, such as: [0003] First, the temperature of the cutting fluid fluctuates greatly before and afte...

Problems solved by technology

[0003] First, the temperature of the cutting fluid fluctuates greatly before and after use. Now that machining requirements are becoming more and more precise, the temperature fluctuation of the cutting fluid will cause thermal expansion and contraction of the cutting tool and the workpiece, which will affect the machining accuracy and cause the rate of defective products. Increase, and may lead to the loss of workpieces, tool scrapping, etc.;

[0004] Second, in the filtration process, there is a process of backwashing the filter equipment, so that the dirt attached to the filter element is stripped by air pressure backflushing. During the backwashing process, the dirty oil pump does not work. However, the machine tool still works as usual, and continues to produce dirty oil (that is, cutting fluid after use), so the filter equipment must make a dirty oil pool to store the newly added dirty oil, and the dirty oil pump will not resume until the backwashing process is completed. Start, and pump the newly added dirty oil to the filter equipment for filtration, so that a large amount of newly added dirty oil may overflow to the clean oil pool during the backwashing process, causing pollution of the clean oil pool and causing oil temperature fluctuations Unstable, and the additional dirty oil pool will increase the volume of the equipment, resulting in an increase in land occupation, purchase, maintenance and other operating costs;

[0005] Third, the existing filtering equipment needs to manually remove the dirt, the operation is very cumbersome, and time-consuming and labor-intensive
