The main filter element of the filter cartridge dust collector is the filter cartridge during its use, and its structure can be effectively divided into four parts: a metal frame, a top cover, a base, and a pleated filter material, and the four-part filter cartridge Round, flat and tapered.
During the design process of the filter cartridge, the length of the filter material is folded into pleats. When used, the cartridge is glued at the end and end of the cartridge. The inside and the outside of the cartridge are supported by a metal frame, and the upper and lower sides are mainly fixed by the top cover and the base. The top cover has the shape of a fixed bolt and washer, a round filter cartridge, and a flat filter cartridge.
The upper and lower end caps of filter cartridges and the guard nets should be reliably bonded. When used, there should be no defects such as degumming, glue leakage, and sagging. The metal parts on the filter cartridges should meet the rust prevention requirements to a certain extent. The outer surface should be free from obvious defects such as scratches, bumps, pulls, and burrs; the cleaning and cleaning of filter cartridges can be equipped with injecting devices such as induction nozzles or venturis as required, and protective nets should be added inside the filter cartridges. 320mm, H ≥ 1200mm filter cartridge should be equipped with induction nozzle.
In the process of designing the filter cartridge, its outer diameter should be larger than the inner diameter of the filter cartridge more than 10mm. This is because of the high and narrow space, which can make the pollution particles slowly on the outer layer of the filter cartridge to a certain extent. Settling, this will make the filter cartridge receive pollution blockage from top to bottom.
The size of the inner skeleton diameter of the filter cartridge is mainly determined by considering that the size of the oil hole should not affect the amount of filtered air, and at the same time, the effect of the size of the small hole on the strength of the skeleton should be taken into account. The total strength of the internal skeleton is very important First, we must consider that the differential pressure on the filter cartridge should be supported by the skeleton, so the smaller the diameter, the higher the strength.
The filter cartridge needs to have enough room for differential pressure. When the required filtration is calculated, the area should be increased by a factor of two. This is because dust pollution is unpredictable in consideration of practical work. There are two types of filter media for filter cartridges: one is a synthetic fiber filter, and the other is a paper filter.
