Bag cage, also known as skeleton and keel, is an essential main accessory of dust remover. It is used as the frame to support the dust removal filter bag. It is the frame of the filter bag and is widely used in the dust removal industry. It should be light and convenient for installation and maintenance. The quality of the bag cage directly affects the filtering state and service life of the filter bag. Our company introduces advanced full-automatic bag and cage manufacturing equipment and uses high-frequency welding machine. The steel wire with good processing performance, high toughness and high-strength steel degree is welded and formed at one time and treated by pickling and leaching process.
During the operation of the dust collector, the quality of the bag cage is closely related to the service life of the filter bag. Our silicone bag cage has superior performance and complete styles and specifications: the split combination methods include plug-in type, plug-in plate type, transfer type, etc. It can be used in most dust collectors. It is an important dust removal accessory in the dust collector, which effectively improves the dust collection effect of the dust collector. The coating quality of silicone bags and cages plays a vital role in the quality, performance and service life of bags and cages. The construction and quality control must be organized according to the coating process requirements. The anti-corrosion treatment should meet the requirements of service temperature, and the surface of the treatment layer should not fall off. The quality shall not be lower than the requirements of JB / t5917-91 standard.
Silicone pretreatment and spraying process:
a. Silicone pretreatment process: degreasing - Pickling - water washing - phosphating - water washing. Objective: to remove oil stains and rust spots on the surface.
b. Silicone spraying process: dehydration - silicone powder electrostatic spraying - high temperature curing.
The reasons why the bag cage affects the damage of the filter bag mainly come from three aspects:
1、 The burr on the surface of the bag cage cuts the filter bag;
2、 If fewer straight bars are used for the bag cage with the same diameter, the deformation range of the filter bag is too large during dust removal and ash removal. Long-term repeated excessive deformation will damage the filter bag;
3、 The bag cage with deformation, desoldering, corrosion and fracture will also cause repeated excessive deformation or friction of the filter bag, resulting in damage.
In order to avoid the problem of appeal, our company has established a perfect quality inspection process. From the incoming inspection of raw materials, self inspection of production line, patrol inspection of inspectors, spot inspection of workshop site managers and warehousing inspection of finished products, each link has set up a "gateway" to ensure the quality. Ensure good product performance and trend in use, and ensure good service life and value in use.
a. The production and inspection of bags and cages shall comply with the requirements of bidding technical specifications and relevant national standards;
b. The bag cage support ring and longitudinal reinforcement are evenly distributed, with sufficient strength and stiffness, can withstand the gas pressure of the filter bag in the state of filtration and ash removal, and can prevent damage and deformation caused by collision and impact during normal transportation and installation;
c. The bag cage shall be welded firmly without desoldering, false welding and missing welding;
d. The surface of the bag cage shall be smooth and smooth without welding scar, unevenness and burr;
e. The surface of the bag cage is treated with anti-corrosion treatment;
f. The surface anti-corrosion coating has good adhesion and uniform coating thickness;
g. The bag cage must meet the working conditions
