Problems solved by technology

However, this process uses the traditional carding and laying method to form a web, which has high requirements for raw materials, and it needs to go through multiple layers of web laying to achieve the required product thickness. In addition, this process uses cleaning to clean the filter bag. The sewage produced by dust removal and cleaning needs to be treated, and the recycling cost is relatively high
[0004] Chinese Invention Patent Application Publication CN1054026A discloses a chemical fiber board and its manufacturing method and equipment, through the steps of opening, carding, webbing, gluing, dehydration, stacking, rolling and other steps to realize the recycling of waste chemical fiber Utilization, although the air-laid process is used in the superposition step, the product needs to be combined with carding, glue invasion and other processes to obtain the product. The process is more complicated and increases the cost of recycling

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] The schematic diagram of the technological process of the method for the present invention to utilize waste fiber to manufacture plate is as figure 1 As shown, waste filter bags are used as waste fiber raw materials in this embodiment, but those skilled in the art can easily understand that using waste textiles as waste fiber raw materials can also realize the present invention, as long as its main component is polyphenylene sulfide fiber , polyimide fiber, polytetrafluoroethylene fiber, polyester fiber, acrylic fiber, glass fiber, aramid fiber, flumes fiber and metas fiber and other fibers. Method of the present invention can be processed according to the following steps:

[0026] (1) Drying: Dry the waste filter bags to keep the water content of the waste fibers below 1%. If there are obvious non-fibrous substances such as steel rings...

Abstract

The invention provides a kind of equipment for making plates by using waste fibers such as waste filter bags and waste textiles. Edge and packing device, the outlet of the air-laid device is provided with a gluing mechanism. The fiber is air-laid by air-laying device, so that the fiber arrangement in the fiber web is non-directional, and the product's horizontal-to-longitudinal ratio is close to 1:1; it is suitable for fibers of various lengths and varieties, and requires little raw material , It can be applied to a wide range of fibers; compared with the traditional carded web to achieve the required product thickness through multi-layer laying, air-laid web can directly obtain the required product thickness by controlling the output speed.

Description

technical field [0001] The invention relates to a device for manufacturing boards by using waste articles, in particular to a device for manufacturing boards by using waste fibers such as waste filter bags and waste textiles. Background technique [0002] At present, the main methods of processing waste fibers such as waste filter bags or waste textiles are incineration and landfill, which will cause air and land pollution. Recycling and reuse of waste filter bags can not only avoid the environmental pollution caused by them, but also improve resource utilization. utilization rate. Although there are many technical and cost problems, the formation of waste filter bag recycling system will still become an irreversible trend, and there are some literatures on the recycling of waste filter bags in China. [0003] Chinese Invention Patent Application Publication No. CN103264040A discloses a process of using waste filter bags to manufacture boards, through recycling, sorting, cl...
