Problems solved by technology
[0002] At present, the temperature-resistant filter cloths of chimneys such as steel, cement, and power plants are all woven from a single glass fiber. This filter cloth has two serious shortcomings: 1. Due to the glass fiber The temperature resistance is average, and the filtering effect is not ideal. Working in an environment of 150-300 ° C, the service life is short; 2. Since only a single glass fiber is used, the diameter gradient pores cannot be formed, and the filtering effect on fine particles in the smoke is poor. Poor, the dust removal effect is not ideal, it is difficult to effectively filter the smoke and dust

Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings.
[0014] like figure 1 As shown, the double-layer filter cloth made of basalt fiber and glass fiber is interwoven with warp yarn 1, surface weft yarn 2 and inner weft yarn 3 to form a double-layer structure. Warp yarn 1 is all composed of glass fiber yarns, and surface weft yarn 2 is also Composed of glass fiber yarns, the inner weft yarn 3 is made of basalt fiber yarns with a lower linear density than the number of glass fiber yarns. The weaving method is to weave the surface layer weft yarn with three upper and lower winding warp yarns 1; the inner layer weft yarn is weaved with one upper layer and three lower winding warp yarns 1, wherein the lower winding of the surface layer weft yarn 2 pairs of warp yarn 1 is separated from the upper winding of the inner layer weft yarn 3 pairs of warp yarn 1 , the adjacent surface weft yarns are staggered by one warp yarn in turn...

The invention discloses a double-layer filter cloth woven from basalt fibers and glass fibers, which comprises warp and double-layer weft, wherein the double-layer weft is divided into inner-layer weft and surface-layer weft, and the inner-layer weft is mainly composed of high-temperature resistant fibers. The filter cloth obviously enhances the strength and temperature resistance and prolongs the service life. Preferably, the yarn number of the inner-layer weft is smaller than that of the surface-layer weft, so that trapezoidal pores can form in the filter cloth and the filter cloth has favorable filtration effect.
Description
technical field [0001] The invention relates to a double-layer filter cloth, in particular to a double-layer filter cloth used in high-temperature operation. Background technique [0002] At present, the temperature-resistant filter cloths of chimneys such as steel, cement, and power plants are all woven from a single glass fiber. This filter cloth has two serious shortcomings: 1. Due to the glass fiber The temperature resistance is average, and the filtering effect is not ideal. Working in an environment of 150-300 ° C, the service life is short; 2. Since only a single glass fiber is used, the diameter gradient pores cannot be formed, and the filtering effect on fine particles in the smoke is poor. Poor, the dust removal effect is not ideal, and it is difficult to effectively filter the smoke. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a high-performance double-layer filter cloth wi...
