GS-LS type basket filter

Basket filter is a pressurized filter with filter basket as the filtering element, which can be installed on the pipeline to remove large particles of impurities in the liquid and protect the normal work of pumps, compressors, instruments and other equipment. The filtering area of the filter basket is 2-3 times larger than the area of the pipe diameter. It is much larger than the filtering area of Y-type and T-type filters. Basket filter is mainly composed of receiver, barrel, filter basket, flange, flange cover and fasteners, etc. It is very convenient to use and maintain. Its working principle is that after the fluid enters the filter basket through the barrel, the solid impurity particles are blocked in the filter basket, and the clean fluid passes through the filter basket and is discharged from the filter outlet. When cleaning is needed, unscrew the screw plug at the lower end of the cartridge, drain the fluid, remove the flange cover, take out the filter basket and reload it after cleaning. This product has been widely used in petroleum, chemical, pharmaceutical, food, environmental protection, biological fermentation and other industries. For example, in the biological fermentation industry, the seed medium and fermentation medium are filtered, and the material inlet of even elimination system is filtered, and the fermentation liquid is put into the tank and filtered, etc.

There are two types of basket filters for pipeline designed by our company with reference to JB/T7538-1994 (the current standard number is JB/T7538-2016): GS-LS/LPG type vertical straight-through (inclined mouth mesh type), GS-LS/LPGG type high and low pipe (straight mouth mesh type). The material of the shell is mainly 304 and 316L, and the inner surface of the shell can be sprayed with PTFE anti-corrosion treatment according to the special requirements of the material; the types of filter basket are stainless steel perforated plate, stainless steel winding sieve tube, stainless steel perforated plate compound stainless steel wire mesh; the material of the filter basket is 304 and 316L, and the surface of the filter basket is sprayed with PTFE treatment, in order to apply to the filtration of materials with different characteristics. If the filtered material contains high quality of magnetic metal debris, consider adding a strong magnetic iron bar on the flange cover of the basket filter (the upper flange cover is replaced by a flat cover) to reduce the content of iron ions in the material and improve product quality. That is: the material flows in from the entrance, adsorbed by the strong magnetic rod, filtered out of the filter basket, impurities are intercepted in the filter basket and strong magnetic rod jacket surface, the filter basket and magnetic rod can be replaced or cleaned and continued to use.

If customers choose our basket filter for filtering low viscosity fluid such as water and steam, they can directly choose the corresponding basket filter model according to the size of the pipeline; if they choose our basket filter for filtering medium and high viscosity materials (such as fermentation medium, high sugar tank inlet filtration, etc.), they can choose the basket filter model corresponding to the size of the pipeline. If the basket filter is installed in front of the pump, it is not suitable to choose too high filtration precision, but if it is installed after the pump, it is possible to choose a higher filtration precision; choose the basket filter material according to the physical and chemical properties of the material.
