Description
Technical Field
The invention relates to a cutting fluid filter tank capable of automatically discharging fluid, which is mainly used for preventing cutting fluid from entering a vacuum source in the process of vacuum adsorption machining of thin plate parts.
Background
The filters commonly used in the filtration system in the machining industry include vacuum paper tape filters, filter element filters, adsorption layer filters, roller filters, gravity filters, and the like. Vacuum paper tape filters are used in most machining industries and are the most common centralized filtration systems. According to the requirements of system precision and flow, a set of coarse filter and a set of fine filter are sometimes configured, and a set of coarse filter and two sets of fine filters are sometimes configured. The whole system has a complex structure and large floor area. The filter element type filter is usually used for superfinishing filtration with high precision and powder-shaped waste scraps in machining requirements, or used for secondary filtration to improve filtration precision. The adsorption layer filter is characterized in that cellulose or diatomite adsorbed on the filter element is used for filtering. The gravity filter is characterized in that the gravity action of the cutting fluid is utilized to enable the liquid to stay on the filter cloth after passing through the filter cloth, scraps and impurities gradually form a filter cake, the flowing resistance of the liquid is increased along with the increase of the thickness of the filter cake, and the liquid level rises. When the liquid level rises to a predetermined position, the filter cloth advances to discharge the filter cake, a new cycle is started, and the clean liquid is reused as a filtration mode. The vacuum liquid purifier is different from a vacuum paper tape filter in that the vacuum filter pumps clean liquid by a pump, vacuum is formed in a liquid purifying tank, and the liquid flow rate is high. At present, the industrial filter for filtering cutting fluid is a closed filter from a single-bag type filter, a double-bag type filter to a multi-bag type filter, and the working principle of the filter is pressure filtration. The complete bag filtration system comprises three parts: a filter container, a support basket and a filter bag. The liquid to be filtered flows in from the top of the filter bag supported by the support basket, the liquid flows from inside the filter bag to outside the bag, and the filtered particulate impurities are trapped inside the filter bag. Therefore, a large amount of harmful bacteria such as anaerobic bacteria are bred, so that the cutting fluid is smelly and deteriorates, once the cutting fluid is changed and smells, the performance is destroyed and cannot be recovered, the cutting fluid needs to be purified and regenerated before being deteriorated, and the cutting fluid needs to be filtered and purified after being separated and then can be recycled. The replacement and treatment of the waste cutting fluid bring much inconvenience to the production, endanger the health of workers, increase the production cost of enterprises and the like. For the aspect of clamping and processing thin plate parts, vacuum adsorption processing is generally adopted, ferrous metals can be processed by adopting electromagnetic technology adsorption and vacuum adsorption according to different methods of different materials, and non-magnetic materials such as aluminum, copper alloy, plastics and the like are generally processed by adopting vacuum chuck adsorption. The method for fixing the sheet part by the vacuum chuck in an adsorption clamping mode is widely applied at home and abroad, the vacuum chuck and the vacuum pump are adopted at present at home, the vacuum chuck is adopted to process the product, the next blank is replaced, a certain amount of cutting fluid remains on the surface of the chuck when the product is removed, when a new blank is replaced and the blank is processed again, the remaining cutting fluid is sucked into a vacuum adsorption system and finally accumulated in a vacuum source in a large amount, so that the vacuum degree in the vacuum chamber is changed, the vacuum system is damaged or the working reliability is reduced, and the labor intensity of operators is greatly increased by frequent cleaning. Therefore, a cutting fluid filtering tank capable of automatically discharging fluid needs to be designed, so that residual cutting fluid in a vacuum adsorption system is filtered and automatically discharged, and the problems that the residual cutting fluid enters the vacuum adsorption system to cause system damage or reliability reduction and the like are solved. Manual cleaning is not needed, and the labor intensity of operators is reduced.
