Advantages of Hengshui diaphragm filter press

The diaphragm filter press adopts the principle of compressed air and is a highly efficient dehydration filtration technology. After the material is compressed through the filter plate, the tympanic membrane is inflated again to achieve a more adequate filtration effect, greatly reducing the moisture content of the filter cake. In recent years, the machine has been widely used in petroleum, chemical, food, electronics, ceramics, textile and other industries. After the feeding process is completed, the filter cake is squeezed under high pressure through the tympanic membrane, which greatly reduces the moisture content of the filter cake. Fully automated processing also reduces a lot of manual labor, and some processes can eliminate the drying process. Let's take a look at the advantages of the diaphragm filter press.

The filter plate used in the diaphragm filter press has membrane filters on both sides. Compared with the filter plate of a membrane filter, the membrane filter has two filter surfaces that can move forward and backward. When compressed medium such as compressed air or liquid passes through the back side of the diaphragm, the diaphragm expands in the direction of the filter chamber, and the filter cake is pressed again with high pressure after the filtration process. Using the filtration process equipped with a membrane filter, the moisture content of the filter cake can be 10-40% lower than that of ordinary filters. Compared with the traditional wing filter, the solid solubility rate of the filter cake can be increased to more than twice, and the transportation cost of the material is also greatly reduced.

The diaphragm filter press needs to select diaphragms of different materials and models to filter materials of different materials to ensure high-quality filtering effect. The materials of the membrane are mountain rubber, cyano rubber, Teflon, etc. Good filtering effect and high quality, thus saving labor and material secondary processing costs, currently occupying a dominant position in all walks of life. Such as paint, coating, ceramics, environmental protection, wastewater treatment, real estate, sludge, chemical industry, etc. When used for fluids with slightly higher viscosity, a reducer or frequency converter must be installed. The same is true for gear pumps.

Advantages of the membrane filter press:

Using low-pressure filtration and high-pressure pressing can greatly shorten the entire filtration cycle.

Using TPE elastomer, the filtration pressure can reach 25MPA, which greatly reduces the moisture content, saves drying costs, and improves the yield.

Saves operating power consumption, as the flow rate is small and the pressure is high in the later stage of filtration.

The diaphragm pressing function completes this process in a very short time, saving energy.

Improves the degree of mud cake dryness and reduces its content. The diaphragm extrudes the filter cake for the second time after static filtration, so that the filter cake structure is rearranged, the density is increased, and part of the water is replaced, improving dryness.

Anti-corrosion, making it suitable for almost all solid-liquid separation work.

PLC and human-machine interface control can be configured.

The diaphragm filter plate has anti-fatigue, anti-aging, and excellent sealing properties.
