1、 The structure of the filter cartridge of the dust collector filter element
The filter cartridge is the basic filtering element of the filter cartridge dust collector, which is divided into four main parts: top cover, metal frame, pleated filter material, and base. The main part of the filter cartridge is formed by folding the designed length of filter material into pleats, and bonding the ends to form an effective filtering area; The inside and outside of the filter cartridge are supported by a metal frame, and are fixed up and down with a top cover and base. The top cover has fixing bolts and washers.
The pleated filter material is the most critical part of the dust removal effect of the filter cartridge, and its filtration accuracy and applicable filtering medium determine its suitable environment. The top cover and its sealing ring are the guarantee of the sealing performance of the filter cartridge, and the rationality of the design of the metal frame of the filter cartridge to a certain extent determines the stability of the filter cartridge.
2、 The main structure of a filter cartridge dust collector
Generally speaking, a dust collector consists of an inlet duct, an exhaust duct, a casing, an ash hopper, a cleaning device, a filter cartridge, and an electrical control device.
3、 Introduction to the installation form of the filter cartridge in the filter cartridge dust collector
The arrangement of the filter cartridge in the dust collector is very important. If the lower part of the dust collector flower plate is the filter chamber and the upper part is the clean air chamber, the filter cartridge can be vertically arranged on the dust collector box flower plate, or tilted and fixed with bolts and rubber pads. In addition, besides being fixed with bolts, the more convenient methods for filter cartridges are automatic locking devices and rubber clamping devices, which are very convenient for installation and maintenance. In response to the universality of these two installation methods, Changwei has produced universal dust removal filter cartridges, quick release dust removal filter cartridges, plum blossom three ear dust removal filter cartridges, outer three ear dust removal filter cartridges, inner three hole lifting filter cartridges, and other filter cartridges with special installation requirements.
4、 The main working principle of filter cartridge dust collector
The working principle of a filter cartridge dust collector is simple and scientific. When dust containing gas enters the dust hopper of the dust collector, due to the sudden expansion of the airflow section, some coarse dust particles in the airflow settle under the action of gravity and inertia. Fine and low-density dust particles enter the filter chamber and are deposited on the surface of the filter material through a combination of Brownian diffusion and screening effects. The purified gas enters the clean air chamber and is discharged through the exhaust pipe and fan.
