Grinding and cooling liquid purification method and device thereof

Abstract

The invention discloses a grinding and cooling liquid purification method and a device thereof, which aims at leading grinding and cooling liquid to rotate and flow nonstop in the whole working process to form vortex; and iron chips and waste chips are concentrated, so the iron chips and the waste chips are discharged by a magnetic separator and a paper filter when the cooling liquid flows nonstop, and thereby the cooling liquid is purified and provided for grinding a workpiece. The invention solves the technical problem that the iron chips and the waste chips in the cooling liquid cannot be thoroughly cleaned so that the cooling liquid can be reused for a long time and is not discharged externally, saves expensive cooling liquid consumption, reduces the production cost, and is not only economic but also environmental-friendly.

Description

technical field [0001] The invention relates to a grinding coolant purification method, which solves the problem of grinding coolant purification and chip removal in high-efficiency grinding, and is mainly used for the treatment of coolant purification in the grinding industry. The invention also relates to a device for realizing the method. Background technique [0002] In the traditional grinding coolant purification treatment, the water tank is made into a square or rectangular box, and isolation sedimentation, paper tape filtration and magnetic separation are mainly used. This method and device has the following problems: 1. The above treatment method is only suitable for grinding The low-efficiency grinding method with less iron filings will grind hundreds of kilograms of iron filings every day in high-efficiency grinding. The above method cannot solve the separation and removal of a large amount of iron filings. 2. In high-efficiency grinding, because a large amount of...

Problems solved by technology

[0002] In the traditional grinding coolant purification treatment, the water tank is made into a square or rectangular box, and isolation sedimentation, paper tape filtration and magnetic separation are mainly used. This method and device has the following problems: 1. The above treatment method is only suitable for grinding The low-efficiency grinding method with less iron filings will grind hundreds of kilograms of iron filings every day in high-efficiency grinding. The above method cannot solve the separation and removal of a large number of iron filings

2. In high-efficiency grinding, because a large amount of grinding iron filings are easily precipitated in the water tank, the grinding iron filings cannot be separated well, which affects the grinding effect

3. Since the iron filings and waste during grinding cannot be separated well, the coolant is easy to deteriorate, and the coolant needs to be replaced in a short period of time, so that the coolant, together with the iron filings and waste, is discharged into the sewer of the factory It affects the surrounding environment, which is not conducive to environmental protection

4. Using the traditional method to deal with the iron filings in the grinding fluid can only remove a small amount of iron filings, and a large amount of iron filings waste exists in the cooling liquid, which makes the cooling liquid easy to deteriorate, shortens the service life of the cooling liquid, and increases the production cost
