What is a cutting fluid filter?
2024-08-22
Cutting fluid filter is the machine tool industry's cutting fluid filtration products collectively. According to the processing capacity can be divided into single machine filtration and centralised filtration, according to the principle of filtration, can be divided into paper belt filter, centrifugal filter, negative pressure filter, positive pressure filter and so on. Nowadays, environmental protection is more and more strict, waste cutting fluid can not be used as ordinary liquid, with industrial wastewater pipeline together with the discharge. The cost of waste cutting fluid treatment is as high as 3200 yuan / tonne. Slightly larger machining enterprises, if not artificially intervene in the use of cutting fluid cycle, the monthly sewage charges will be a considerable expenditure.
Cutting fluid filtration, how to choose the most suitable for their working conditions of the cutting fluid filter. Yantai Qiyang Machinery Co., Ltd. of small Yang with you to understand:
1, small paper belt filter
Small paper belt filter, generally known as the flat network filter, suitable for single machine tools, processing capacity is generally 50L/min-200L/min, a customer has special needs, can do 300L/min.

2、Drum filter
Rotary drum filter, is also a kind of paper belt filter, also rely on gravity, cutting fluid in the impurities are filter cloth retained, filtered cutting fluid falls into the tank, through the liquid supply pump back to the machine tool, re-use. The rotary drum filter occupies less space than the flat screen filter, and the filtration efficiency is higher. It is suitable for slightly larger processing conditions. It is recommended to choose drum filter for 300L/min-800L/min processing capacity.

3、Magnetic separator
When there are more iron chips, if we rely on the paper belt filter to filter the impurities in the cutting fluid, the consumption of filter cloth will be very large. Before the cutting fluid enters the paper belt filter, we will carry out the first stage filtration by magnetic separation to reduce the consumption of filter cloth through the magnetism principle of iron chips.
