The cooling liquid collecting and filtering system is used to collect and collect the grinding fluid in the production workshop; it has significant advantages compared with the cooling liquid supply system of the single machine and the separate supply. It can carry out the cooling liquid. Concentrate filtration, degreasing, aeration, sterilization; complete control of its concentration, pH and number of colonies; then ensure that the coolant does not undergo metamorphism; extend the service life of the coolant. Concentrate filtration of the coolant; The production cost is reduced; the labor intensity of the workers is reduced; the working environment of the workshop is improved; the environmental pollution is reduced together; the collection and disposal of the waste coolant can be completed; and then the environmental pollution is further reduced. Importantly, the cooling liquid is collected. The filtration system stabilizes the quality of the coolant for a long time; it ensures the demand for grinding of the bearing ring.
3. Super essential oil collection filter system Super essential oil filtration system consists of super essential oil filter and filter aid coating machine plus oil tank and pipeline valve. Mixing diatomaceous earth and clean oil before starting the filtration; After the mixing is completed; the liquid is transported by the pump on the coating machine to the filter for precoating of the filter layer; the diatomaceous earth precoating application amount is 0.5 to 1 kg/m2; The concentration of the coating liquid is 0.3 to 0.6%; the circulating speed of the precoating liquid is 0.15 to 5 cubic meters per hour square meter. When the outer surface of the filter cloth is coated with a proper thickness (1.5 to 2 mm) of diatomaceous earth layer Ultra-precision oil filtration accuracy of 2 ~ 5μm. Currently in the ultra-essential oil filtration; the system is more ambitious in terms of operating costs and filtration. Super-fine oil filter because the filter plate and filter media are horizontally placed; The filter layer is uniform; it can be intermittently filtered without pressure and will not damage the pre-coating.
Usually, the bearing processing machine can be attached with a separate filtering system when it leaves the factory; however, the filtering system has low filtering precision; it can only satisfy the demand for low-precision bearing production; it cannot meet the demand for high-precision, low-noise bearing. In the case of a large number of machine tools The ultra-essential oil filtration system that uses this set of oil supply methods is an extremely ambitious plan; it can completely eliminate the filtration system of the original machine tool when acquiring the new machine tool and transforming the original filtration system; the cost performance is obvious. The actual situation; the plan needs to be able to make alignment corrections.
3. Investment, income analysis and implementation advocates to collect grinding fluid; can improve cooling and anti-rust function; extend the use time of grinding fluid, improve the precision of bearing ring ultra-precision, protect the environment, produce health; make the wheel ash get the disposal .
Gathering grinding fluid; filter or other methods of filtration; filtration accuracy ≤ 20um; filtration flow: 3000L / min, collecting super essential oil; filter or other methods of filtration; filtration accuracy ≤ 10um; filtration flow: 800L /min.
Practice has proved that the use of coolant collection filter system in the field of bearing grinding, the quality control of the product, the environmental requirements of the working environment and the best cost performance of the product, is a sophisticated and reliable method. Dealing with, bringing great economic benefits to the company, will also bring out outstanding social benefits.
The grinding process requires the use of grinding fluid; once every grinding machine used 0.5 cubic meters of water per day; then it was completely renewed; on the one hand, it was a great waste of water resources; on the other hand, wastewater formed environmental pollution; nowadays It uses the water supply circulation room; it supplies water to each machine through the pipeline; the equipment can be used for 3 years per water supply. This reduces labor intensity, pollution reduction and water conservation.
The grinding fluid collection system can not exceed 500,000 yuan in one-time investment; it can dispose 50 grinding water supply; the investment cost of equipment can be recovered within 3 years.
Before using the super-essential oil to collect the filtration system; the super-essential oil is replaced once by the oil in one month; the application amount reaches 200 kg/month; after use, it is treated as waste oil. After the super-essential oil is used to collect the filtration system; the current is 5 tons of oil pool; Only 5 tons of oil can be used for 20-30 machines per year.
The collection and filtration system of grinding fluid and super essential oil has great implementation value; one-time investment is not large; however, the resource saving effect is significant; the social effect is good; the demand for plant transformation is not high.
