How much do you know about rolling diaphragms? Next, we will introduce the diaphragm filter press, which is composed of a diaphragm plate and a box. The diaphragm filter press utilizes the pressure of the diaphragm to press, and the hydraulic rotary diaphragm filter press. The rubber diaphragm filter press is compressed, and the rear filter plate is lifted and lowered. There is also a plastic diaphragm inside the diaphragm filter press, which is an embedded press diaphragm filter press.
Diaphragm filter press is an intermittently operated pressure filtration equipment suitable for smaller filtration areas and more dust, mainly used in industries such as food, medicine, chemistry, beverage, chemical, pharmaceutical, etc.
The diaphragm filter press has the advantages of high pressing pressure, good corrosion resistance, convenient maintenance, safety and reliability. It is the first choice for customers in industries such as metallurgy, gas, papermaking, coking, pharmaceutical, food, brewing, fine chemical, etc.
Diaphragm filter presses have been widely used in various fields that require solid-liquid separation. Diaphragm filter press is considered as an alternative upgrade equipment for ordinary box filter press.
The diaphragm filter press has shown good results in terms of processing capacity per unit area, reducing filter cake moisture, and adaptability to the properties of the processed materials.
The diaphragm filter press is applied to sludge and sewage treatment, and the minimum moisture content of the filter cake has reached below 60%. Compared to traditional box type filter presses, the solid content of the filter cake can be increased by more than 2 times, and the transportation cost of the filter cake is greatly reduced. The filter cake can enter the power plant and be directly burned, truly turning sewage into a resource and sewage into a clear spring, completely replacing the box type filter press.
For different diaphragm materials, the new generation of diaphragm filter presses can be divided into rubber diaphragm type and polymer elastomer diaphragm type.
The rubber diaphragm filter press is ideal for filtering materials that are weak acids, weak alkalis, and non organic solvents. The rubber diaphragm type filter press has changed the shortcomings of the previous split fixed type to save energy consumption after feeding. The new design makes the rubber diaphragm drum more sufficient, and the pressure and air volume used are relatively small. Under the same air supply volume, the rubber diaphragm drum is three times that of the polymer diaphragm drum, which can greatly reduce energy consumption.
Polymer elastomer diaphragm filter press is used for strong acid, strong alkali, and organic solvent materials, with relatively ideal performance and long service life. Its pressing forms are divided into gas (air) pressing and liquid (water) pressing, which can meet the needs of different industries. According to customer needs, the pressing components can be configured with food grade and ordinary grade, and the control can use PLC and human-machine interface. For general materials, fully utilize the function of squeezing and dehydration. For some special materials, the segmented pressing method of first low-pressure pressing and then high-pressure pressing can also be used.
The extension of the complete press diaphragm filter press will result in a moisture content of the filter cake. At 60% stroke, the maximum supply component can only be used for dehydration of the water pump.
