Dust-removing skeleton is named after its work nature, which is the framework of dust bag, it is equivalent to human bone shelf, and plays the role of lifting uplifting for dust bag, equivalent to the rib of bag filter, also called dust-removing frame. Dust bag cage. It has played a decisive role in dust bag and bag filter. Without the support of the dust-removing frame, the dust-collecting bag cannot complete the entire process of cleaning, and the bag filter cannot play its role.
Dust removal frame installation precautions:
Before the installation of the dust removal frame, it is necessary to check whether the quality of the dust bag and the dust removal frame are qualified. The bag requires no off line, jumper, wireless head, and the bag size must match the frame diameter. Also check that the material of the bag matches the order. If there is a difference, please contact the supplier as soon as possible to exchange. The high-quality dust-removing frame requires a smooth surface, no burrs, and no leakage welding. The easiest way is to open the welding area on my eyes, to use the white gloves on the handbag, and not to hang the thread.
Good dust-removing framework should have sufficient strength, stiffness, verticality and dimensional accuracy to prevent pressure deformation, damage during transportation, contact of dust filter bag after loading into dust collector, difficulty in bagging, friction of bag frame, etc. Occurrence; In the production process, all the solder joints must be solid, do not allow desoldering, welding and missed weld; require a smooth surface, straight, no burrs, uniform welding. Surface treatment can be sprayed or silicone treated. There is a choice of galvanized or stainless steel for temperature and humidity that require corrosion protection.
Dust removal frame filter:
Filled Filter Bed Filtration: Filled filter bed is a kind of porous filter material such as foamed plastic, non-woven fabric, plush, etc. on the mesh roller, flat plate and other components. With its good surface filtration and internal filtration, the dust is separated from the air stream. The advantages of the packed filter bed filtration are large air volume, low resistance, and dust filtration.
Dust-removal frame filter bag filter: The dust bag is a cylindrical body surrounded by a single layer of fabric, usually round, characterized by a simple structure, easy to remove dust. When the dust-laden air passes through the filter bag, the dust is separated from the air flow by means of screening, collision, interception, and the like. Dust filter bag filter has the advantages of high filtration efficiency, dust removal efficiency of more than 99.5% in the textile dust chamber, simple structure, low power consumption. The disadvantages are that they are prone to fire, the filter bags are easy to dew, the filtered air volume per unit area is small, and the amount of filter cloth is large. In the short time after cleaning, the dust concentration in the filtered air is high and the working conditions are poor.
The mechanism of filter dust removal by dust removal framework is the comprehensive action of short-range capture mechanisms such as sieving effect, direct interception, diffusion settlement, inertial impact, and electrostatic adsorption. When dust-laden air passes through filters such as meshes, fabrics, nonwovens, foams, etc., dust is trapped in the dust layer formed inside or on the surface of the filter, and the filter layer formed on the upper layer of the powder is removed from the air stream. Separated. With the thickening of the dust layer, it is necessary to regularly remove the dust layer to ensure that the dust removal process continues. The textile fiber dust collector is classified according to the structure of the dust collector. The textile fiber dust collector has the dust cage filter, the packed filter bed filter, the filter bag filter dust remover and so on.
