Embodiment Construction

[0006] An improved manufacturing method of the filter bag head. The leftover material of the filter bag is used to make a concave pad, the concave pad is attached to a spring steel sheet to make a synthetic part, and a filter bag material cloth is folded in half and covered with the synthetic part. Then overlap the two layers of filter bag material cloth skirt at one end of the synthetic piece on the outside of the filter bag mouth, and sew it into one.

[0007] The price of concave pads made of rubber rings on the market is 0.8 yuan / piece, and the cost of the cloth concave pads of this application is only 0.4 yuan / piece, which greatly reduces the production cost, and at the same time, the emission of exhaust gas and dust is lower and stable.

[0008] The head of the antistatic filter bag sewn with rubber ring-type single-layer cloth will be damaged and the filter bag will fall off after three to six months of use. The filter bag of this application has not been damaged for a y...

Abstract

The invention relates to a making method of an improved filter bag mouth. The method comprises the following steps of: making a concave pad by using cloth for making a filter bag; attaching the concave pad to a spring steel sheet to make a synthetic piece; fording filter bag material cloth to wrap the synthetic piece; and stacking the skirts of two layers of filter bag material cloth at one end of the synthetic piece outside the filter bag mouth to be sewed together. By improving the concave pad material and the sewing method of the filter bag mouth, the filter bag mouth can resist aging, softening and dust, and has lower and stable dust discharge amount of tail gas dust; and the filter bag hardly falls in use and has long service life and decreased making cost.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, in particular to an improved method for manufacturing a filter bag head for gas-solid separation. Background technique [0002] The existing design of the head of the filter bag mainly includes a concave pad fixed on the orifice plate of the dust collector, that is, a rubber material with grooves is attached to a spring steel sheet to make a synthetic part, and then the head of the filter bag is turned over and wrapped. The overlay is sewn directly into the piece. This kind of filter bag head design will cause the following problems in the production process: the rubber concave ring is easy to age and soften. Especially when the working temperature exceeds 130°C, the aging speed will be accelerated, which will easily cause the bag to fall off, which will increase the maintenance cost of the user. In addition, because the head is directly sewn with a single layer of fi...
