What you want to know about the rolling diaphragm is to popularize its Mode of action here: through the reverse laying of the diaphragm, the shell of the diaphragm shell is made of porcelain molding, and the diaphragm is evenly cut by air distribution and moisture dispersion. The patch is located above the diaphragm, and is not limited by the characteristics of the base material. The tensile strength is greatly improved, which greatly improves the working efficiency of the diaphragm and greatly improves the service life of the diaphragm sections.
The diaphragm filter press consists of a diaphragm plate and a box type filter pressed together. The two sides of the filter plate of the diaphragm filter press are covered by filter cloth, and the two sides of the diaphragm are covered by filter cloth. When a press diaphragm is required, a set of filter plates consists of a diaphragm plate and a box type filter plate. The diaphragm filter press utilizes force on one side of the diaphragm to clamp the entire filter plate, thereby separating solids and liquids.
The sludge filter press is applied to sludge and sewage treatment, and the minimum moisture content of the filter cake has reached below 60%. Compared with traditional box filter presses, the solid content of the filter cake can be increased by more than 2 times, and the filter cake can be filled with block filter plates.
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, after 3 to 15 minutes, the diaphragm drum can fully exert its squeezing and dehydration effect. For some special materials, the segmented pressing method of first low-pressure pressing and then high-pressure pressing can also be used.
The diaphragm filter press produced by “Hangzhou Jianhua Filter Press Manufacturing” moves the filtrate back and forth, making the diaphragm press better through the filtering medium (filter material), further improving the filtration effect. The diaphragm filter plates provided by Hangzhou Jianhua Filter Press Manufacturing include split type high-pressure polypropylene diaphragm filter plates, integrated high-pressure polypropylene diaphragm filter plates, embedded filter cloth high-pressure polypropylene diaphragm filter plates, and rubber diaphragm filter plates. Diaphragm filter plate has the characteristics of fatigue resistance, aging resistance and good sealing performance.
Significantly shorten the filtration operation time. In the later stage of filtration, the filtration efficiency is extremely low. By using the diaphragm pressing function, this process can be completed in a very short time, greatly improving the efficiency.
Improve the degree of mud biscuits, reduce the content of mud cakes, and perform secondary pressing on the filter cakes after static filtration by diaphragm pressing, thereby improving the filtration efficiency< Eod>.
