Preparation method and apparatus for glass fiber filtering material

Abstract

The invention relates to a preparation method for a glass fiber filtering material. The preparation method comprises the following concrete steps: mixing feldspar, soda ash, boric acid, barium carbonate, potash, limestone and other raw materials and preparing a glass ball; fusing the glass ball in a kiln so as to obtain glass liquid; carrying out primary wire drawing on a bushing plate and blowing drawn wires with flames in a combustion chamber so as to obtain glass fiber; allowing the glass fiber to pass through a bell mouth cotton collection chamber and to be mixed with a binder at an outlet so as to obtain glass cotton felt; allowing the glass cotton felt to be absorbed on a non-woven fabric located at the upper layer of a wire belt of a cotton collection apparatus under the action of a negative pressure blower fan; and carrying out curing in a curing furnace so as to obtain the glass fiber filtering material. According to the invention, the glass fiber prepared by using a flame blowing method has good uniformity, a small diameter and high strength; the glass fiber cotton is cooled in the bell mouth cotton collection chamber so as to allow the glass cotton felt to maintain good filterability; and the prepared filtering material has high filtering efficiency, can filter out impurities with small particle diameters and has long service life and a wide application scope.

Description

technical field [0001] The invention relates to a filter material preparation device and method, in particular to a glass fiber filter material preparation method and device, belonging to the filter material field. Background technique [0002] Filtration is when the liquid (or gas) in the suspension (or the heating gas containing solid particles) penetrates the medium under the action of driving force or other external force, and the solid particles and other substances are trapped by the filter medium, so that the solid and other substances and the liquid ( or gas) separation operation. Therefore, the requirements for filter materials are higher, and they need to have better mechanical properties, usability and filtration properties. [0003] The Chinese patent with the publication number of 1698949A provides a filter material for adsorption and purification. The chemically modified granular activated carbon is distributed on one side by means of air flow, and it is a thr...

AI Technical Summary

Problems solved by technology

Install a trumpet-shaped cotton collection chamber to cool down the glass fiber to prevent the adhesive from partially curing due to high temperature when mixed with the adhesive, and prevent the liquid glue from expanding to the surface of the monofilament fiber in the fiber bundle through capillary gravity. Incrustation on the surface of the bundle will lead to poor uniformity of the glue in the fiber and affect the filtration performance of the glass wool felt
