1. Classification of dust removal skeleton
Cylindrical, oval, diamond, envelope, flat, envelope, trapezoid, star, spring.
Second, the production of dust removal skeleton
The bag cage, also known as the skeleton, is formed by one-time welding with special equipment. The quality of the skeleton directly affects the working state and service life of the filter bag. The company introduces advanced welding technology to not only ensure that each skeleton that leaves the factory is welded firmly, the appearance is smooth and straight, but also The welding speed is greatly improved, and the company’s annual production capacity is several million meters, and the surface is galvanized or sprayed after post-processing. Commonly used are circular skeleton, multi-joint skeleton, trapezoidal skeleton and spring skeleton. Other surface treatments can also be carried out according to the specific requirements of customers’ working conditions, and various skeletons can be customized.
1. With a circular structure, the longitudinal ribs and anti-stretching rings of the bag cage are evenly distributed, and have sufficient strength and rigidity to prevent damage and deformation. The bag mouth is safe when blowing.
2. The frame of the filter bag has enough rigidity to withstand the gas pressure of the filter bag in the state of filtration and cleaning, ensuring that the plastic deformation is less than 3MM after running under 3000PA negative pressure for 1H, and the solder joints have no de-soldering phenomenon.
3. All welding points of the filter bag frame are firmly welded, and the surface of the welding area is smooth and free of cracks and pits. No desoldering, virtual soldering and missing soldering.
4. The surface of the filter bag frame in contact with the filter bag is smooth and clean, without welding scars, unevenness and burrs.
5. The surface of the filter bag frame is treated with anti-corrosion and temperature resistance, and the treated layer has no peeling.
6. The skeleton material is made of 20# carbon steel, and the skeleton production line is used for one-time forming to ensure straightness and distortion. The filter bag frame is smooth and burr-free after butt welding, and has sufficient strength to prevent de-soldering, de-soldering, virtual welding and Leakage phenomenon.
7. The bag cage adopts spraying technology, and the coating is firm, wear-resistant and corrosion-resistant, which avoids the rust of the skeleton surface and the bonding of the filter bag after the dust collector works for a period of time, ensures the smooth bag change, and reduces the bag change during the bag change process. damage.
3. Requirements for attention when the skeleton of the dust collector
The dust removal framework used by the dust collector generally needs to pay attention to the fact that the framework itself cannot have burrs or welding breakpoints. Most of the frameworks we use at present are processed, such as galvanized, chromed, etc., in order to prevent the dust collector. The skeleton is affected by the operating environment in the process of use, and it will be corroded and broken early, which will affect the dust removal efficiency and the operation of the entire dust collector.
Whether there are burrs on the dust removal frame determines whether the dust removal filter bag has a longer life. The burr will cause scratches and scratches to the filter bag during the dust removal process. After the dust removal filter bag is damaged, the dust accumulated in the whole dust removal process will be discharged with the wound. At this time, the entire dust removal equipment must be stopped, which will greatly affect the dust removal. efficiency and the entire production process.
