With the development of the times, our quality of life is also improving rapidly. Negative pressure filter quality requirements are higher, the producer higher requirements for equipment, the following small make-up to see the negative pressure filter selection method!
First of all, the filter factor should be considered when selecting the filter.
The factors affecting filter selection are temperature viscosity, physical chemical characteristics, treatment capacity per unit time, moisture content of filter cake, solid content of filtrate washing degree of filter cake.
The comparative advantages of vibration filter plate frame filter press;
1. Mechanical slag removal; 2. Stainless steel filter plate; 3. Small floor space; 4. Good air tightness, energy saving environmental protection.
The application conditions of the negative pressure filter are as follows:
1. The slag content is less than 5%; if a larger dehydrator between 10 20 is recommended, the model is generally glj-40-80.
2. Liquid fluidity: viscosity less than 80;
3. Working environment: (1) the temperature is generally about 80-150 (mainly depending on the fluidity of the liquid). (2) It is corrosive. Acid alkali corrosion requires that 316L stainless steel should be used for some filter plates with higher materials; if the corrosion of solvent oil requires higher sealing materials, polytetrafluoroethylene is generally used.
4. Slag properties: specific gravity particle size are the main factors to filter plate accuracy.
Bag filter is generally the auxiliary equipment of vibrating slag filter plate frame filter to further ensure its filtering accuracy to meet the standard. Similarly, the viscosity is low the solid content is less than 0.01. The popular one is also called protection filter.
Paperboard column filtration are mainly used to remove high-precision ultra-fine trace slag.
The auxiliary accessories of vibration slag removal filter include gear pump, air pump, pneumatic butterfly valve, etc. The type of gear pump directly affects the flow rate of filtration. The pressure of air pump controls the drying, wetting thickness of filter cake the light degree of slag discharge. Pneumatic butterfly valve is mainly used for pneumatic switch, seal discharge.
The cake can be purified by repeated washing pressure filtration.
Parallel connection of two vibration slag removal filters can realize continuous operation, PLC control system can also be set up, which is of relevance importance to the selection of filters.
The above content is about the negative pressure filter selection method summary. I believe that we all have a certain understanding, hope to help you. If necessary, welcome to consult, we will serve you wholeheartedly. For more information, please continue to pay attention to our official website!
