How is the dust removal framework made

Circular dust removal framework is a very important product of bag type dust removal accessories. It is the structure of external filter type dust removal cloth bag. This kind of dust removal framework should have the characteristics of light weight and convenient assembly and repair. The quality of the dust removal framework of a dust collector directly determines the service life of the dust removal cloth bag.

The circular dust removal framework is generally manufactured by production equipment at one time. The dust removal framework manufactured in this way is welded firmly and has a smooth and straight appearance. The transportation, production and processing of the dust removal framework should conform to the manufacturing specifications required by the Ministry of machinery industry. The main manufacturing requirements of the dust collector framework are that it should have strength, rigidity, straightness and scale accuracy, which can effectively prevent the deformation and damage of the dust removal framework of the dust removal accessories. It is required that all the welding points of the dust removal framework shall be consolidated, and there shall be no desoldering, missing welding and false welding. The surface of the framework contacting with the dust removal cloth bag shall be lubricated, and no welding scar and burr shall be present.

After the dust removal framework is formed, the surface treatment shall be carried out according to the working conditions.

Dust removal framework galvanizing: Framework galvanizing is generally applied at normal temperature.

Galvanizing can make the skeleton appearance lubricated, and the coating is solid, which can prevent the appearance of the dust removal skeleton from rusting and bonding with the filter bag after operation, and also ensure the smooth bag replacement and reduce the damage to the filter bag during the bag replacement.

Plastic spraying or silicone framework: silicone spraying can be applied at relatively high temperatures, can be used to maintain bags and cages, and also has anti-corrosion effect.

The appearance treatment of the dust removal framework depends on the application environment of the framework. Generally, under normal temperature and low corrosion conditions, the zinc plating process with low cost can be selected; Under the working conditions of high temperature and corrosion (such as dust removal equipment for coal-fired boilers), plastic spraying or silicone spraying is required.
