The spring skeleton is a necessary supporting product of the external filter type dust collector. It is divided into two kinds of Venturi tube and no venturi tube. The spring skeleton has a certain degree of scalability. Because the dust collector is limited by the indoor space, there is no space for the top of the dust collector to replace the dust removal skeleton, so the spring skeleton is adopted in the design.

The diameter of the spring skeleton is generally less than 130 millimeters. It is coiled with steel wire with a diameter of 5 millimeters. Generally it is 35 circles / meters after stretching. The stretching length is generally 1.5M, 2M, 2.5M. After treatment, the galvanized surface is treated, and the spring skeleton design structure is strong and reliable, and the service life is longer.

The spring skeleton is easy to install and maintain, and the quality of the frame directly affects the filtering state and service life of the dust filter bag. Galvanized, sprayed, and organosilicon plating. The spring skeleton has a certain degree of scalability. Because the dust collector is limited by the indoor space, there is no space for the top of the dust collector to replace the dust removal skeleton, so we use the spring skeleton or the multi section dust removal skeleton in the design. The spring skeleton is more convenient for transportation.
