Description

Technical Field

[0001] The utility model relates to the technical field of dust removal bags, in particular to a glass fiber bag with a long service life. Background Art

[0002] Fiberglass bags, also known as glass fiber bags, are a widely used filter material. Glass fiber bags are mainly composed of glass fibers and various resin matrices. They have excellent high temperature resistance, corrosion resistance, wear resistance and other properties. With these characteristics, they perform well in high temperature, high pressure and highly corrosive environments. They are widely used in industrial dust removal, air purification, oil-water separation and other fields.

[0003] To this end, China's patent application number is CN210448430U, which discloses a glass fiber dust bag that is easy to fold. It belongs to the technical field of dust bags and includes a fixed cylinder and a first fixed seat. The outer side of the fixed cylinder is provided with a protrusion. The outer side of the dust bag is provided with an extrusion mechanism. The inner sides of the first extrusion plate and the second extrusion plate are both provided with grooves. The glass fiber bag is provided on the side of the wear-resistant layer away from the metal mesh layer. The upper end of the first fixed seat is provided with a first fixing rib, and the upper end of the second fixed seat is provided with a second fixing rib. The utility model provides a metal mesh layer and a wear-resistant layer, so that the dust bag is easy to shape when squeezed and easy to fold. By wrapping the dust bag around the outer side of the fixed cylinder and closing the extrusion mechanism, the protrusion is inserted into the groove, thereby squeezing and folding the dust bag, improving work efficiency, effectively increasing the filtration area, and improving the purification and dust removal effect of the bag dust collector.

[0004] Today's fiberglass bags can basically meet people's needs, but there are still some problems. The specific problems are as follows:

[0005] 1. It is difficult to avoid the problem of fiberglass bags falling off during use. During the use of fiberglass bags, they will be constantly impacted by wind. Since the hardness of the bags themselves is not high, they are prone to deformation during use and fall off from the installation place, causing the dust inside the dust collector to leak into the environment, affecting the dust cleaning effect of the dust collector.

[0006] 2. It is difficult to extend the service life of fiberglass bags. In many industrial applications, fiberglass bags need to face the erosion of corrosive gases or liquids. These corrosive gases or liquids will cause the structure and performance of the fiberglass bags to deteriorate rapidly, resulting in decreased filtration efficiency and bag damage, increasing maintenance and replacement costs.
