What is the filter of the cartridge
Dust Collector? The filter element of the filter cartridge dust collector is the filter cartridge. The structure of the filter is divided into four parts: top cover, metal frame, pleated filter and bracket. These four-part filter cartridges are round, flat, conical, etc.
Filter The filter of the design length is folded into pleats, the end is supported by an adhesive cylinder, the inside and outside of the barrel is supported by a metal frame, and the top and bottom are fixed with a top cover and a bracket. There are fixing bolts and washers on the top cover. Round filter, flat filter shape.
The top and bottom cover of the filter screen and the protective net should be bonded reliably, and there should be no defects such as degumming, water leakage, and oil. The metal parts of the filter must meet rust-proof requirements. The outer surface of the filter should not have obvious defects such as collision, plucking, and burr. For the spray cleaning of the filter cartridge, you can use a spray device such as an induction nozzle or a venturi tube as needed. A protective net needs to be added inside the filter cartridge. It is best to use an induction nozzle when choosing D320mm and H1200mm filter cartridges.
The volume of the finished filter cartridge has a great relationship with the total volume of the filter cartridge. The host using the filter assembly usually puts forward the following requirements for the filter: the total height of the dust collector and the distance (width) of the inlet and outlet; the total height and diameter of the lower body of the filter cartridge; the total mass of the filter screen; the connection method and size of the exhaust port; A series of performance requirements related to filtering characteristics, such as filtering accuracy.
The filter design should pay attention to the following factors according to the total set requirements.
(1) The outer diameter of the filter is preferably larger than the inner diameter of the filter by 10mm or more. Because the high, narrow space allows the pollution particles to slowly sink to the outside of the filter, the filter can be evenly intercepted by pollution from top to bottom.
(2) The determination of the diameter of the internal bone should mainly consider that the size of the light oil hole does not affect the filtering air volume, and the impact of the size of the hole on the strength of the bone.
(3) The overall strength of the internal skeleton is very important. First of all, the skeleton should be used to support the differential pressure of the filter cartridge, so the smaller the diameter, the higher the strength.
(4) The height of the wrinkled teeth should be selected between l0 ~ 50mm mm.
(5) To leave enough room for differential pressure limit, after calculating and accumulating the necessary filtration, double this area. Because dust contamination is unpredictable in real work.
What is the filter material of the filter cartridge dust collector?
There are two types of filters for filters: one is a synthetic fiber filter and the other is a paper filter.
Synthetic fiber non-woven fabric filters can be divided into continuous fiber spinning polyester hot pressing and short fiber spinning polyester hot pressing according to different processing techniques. In the waterproof treatment of the filter surface, the infiltration angle of the filter after waterproof treatment must be greater than 90, and the water immersion level cannot be lower than the grade. Filter oil-proof treatment conditions, filter oil-proof treatment. Polyester non-woven filters can withstand operating temperatures above 120. Under other special working conditions such as high temperature and high humidity, the selection of filter material structure must meet the application requirements.
Paper filters can be divided into two categories: low air permeability and high air permeability.
There are also synthetic fiber non-woven polyethylene coated filters and paper polyethylene coated filters.
