The cascade filter is widely used in pharmaceutical, chemical, food, beverage, water treatment, brewing, ink, oil, printing and dyeing, environmental protection and other industries It is an ideal equipment for all kinds of liquid filtration, clarification and purification Polypropylene material, corrosion-resistant, durable, especially in stainless steel is more expensive to use polypropylene is greatly reduced cost According to different filter media and production process, the machine can be equipped with microporous filter membrane to achieve the purpose of sterilization treatment It can also reduce or increase the number of filter layers according to the size of filter volume, so as to make it suitable for production needs The sealing parts of the machine are medical silicone rubber or fluororubber, no leakage and good sealing performance The laminated filter has the advantages of large filtering area, small volume, small occupied area and small space The double screen plate of the machine is used for filtering to ensure large filtering surface, light weight and convenient operation And the area of the horizontal plate and frame filter can also be large, which is large in volume, heavy in weight and inconvenient in operation
The laminated filter also has a unique system with backwash device and heat preservation and heating device (mainly to block the filter membrane and replace the filter membrane during filtration), so as to prolong the working time and increase the cost of consumables, so as to design the backwash device and heat preservation and heating system The machine is also equipped with a set of special microporous filter membrane with backwash device and heat preservation and heating), which is mainly used in chemical industry, pharmaceutical industry and other industries, It is a new advanced filtration equipment in the market at present to solve the problems of low temperature crystallization of liquid and viscosity of some liquid at low temperature Cascade filter is used to eliminate impurities in the medium to protect the normal use of valves and equipment Function of the filter: (1) oil absorption filter: the filter is set on the suction pipeline of the pump, which can filter out the pollutants entering through the air hole of the residual pollutants in the oil tank and protect the pump Therefore, it is not a filter to control the pollution concentration of the system (2) high pressure pipeline filter (a): it is set on the outlet pipeline of the pump to protect pollutants from entering the system Therefore, the pollutant concentration of the system can be controlled However, because it is a high-pressure main pipe, it is subject to the pulsation and pressure impact of the pump, so the material and strength of the filter element should be carefully considered (3) high pressure pipeline filter (b): in the system, in order to protect the hydraulic parts that are particularly sensitive to pollution, the filter is installed, also known as the terminal filter Therefore, it is often smaller than other filters Therefore, large capacity should be selected when using In addition, the material and strength of components shall be fully considered as (a) (4) return filter: it is set on the return pipeline of the system, and its function is to capture the pollutants generated or intruded in the system before returning to the oil tank Therefore, it is an important filter to control the pollution concentration of the system Although it is a low-pressure pipeline, there will be pulsation or pressure impact according to the operation condition of the transmission device, so the material and strength of the components should be fully considered Imported pump (5) circulation filter: it is set on the oil return road of the oil tank circulation The system has a large capacity, so it is often used when strict cleanliness is required Even if the system is not working, pollutants in the oil tank can be collected Therefore, the efficiency of reducing pollution concentration Zui is good In addition, the cooler is installed, which has the advantages of simultaneous cooling and easy maintenance But it needs to use special pump and motor, so the cost is high (6) air filter: it is set on the oil tank to prevent pollutants from mixing into the oil tank with air due to the change of oil volume of the oil tank Therefore, the filter accuracy should have the same performance as the bag filter, and the capacity should have enough room to prevent the internal pressure of the oil tank from becoming negative pressure due to the hole blockage, which will cause the pump cavitation Pay special attention when the surrounding environment is bad.
