Embodiment 1

[0045] The aramid superfine fiber needle-punched filter bag includes a bag body, a bag head and a bag bottom. One end of the bag body is fixed with the bag head, and the other end of the bag body is fixed with the bag bottom. The bag body includes a base fabric layer and a protective layer. The protective layer is respectively fixed on both sides of the base fabric layer, and the protective layer is composed of the following components in parts by weight: 50-65 parts of polytetrafluoroethylene concentrated dispersion, 0.8-1.5 parts of coupling agent, 8-15 parts of silicone resin 3-10 parts of antistatic agent, 10-15 parts of antibacterial agent, 0.2-0.5 part of antioxidant and 40-60 parts of deionized water. After using this component, the main raw material of the protective layer is polytetrafluoroethylene. Concentrate the dispersion liquid, and add an appropriate amount of coupling agent, silicone resin, antistatic agent, antibacterial agent, antioxidant and deionized water i...

Abstract

The invention provides spraying and drying equipment for an ultrafine aramid fiber needle-punched filter bag. By adoption of the spraying and drying equipment for the ultrafine aramid fiber needle-punched filter bag, the technical problems that an existing filter bag does not have the characteristics of corrosion resistance, electrostatic resistance, the antibacterial property and the like, can only be used in simple environments, and is poor in functionality are solved. The spraying and drying equipment for the ultrafine aramid fiber needle-punched filter bag comprises a rack, and a spraying device and a drying device are arranged on the rack. The spraying device comprises a isolation box, a delivery pump and a storage box, wherein a cavity is formed inside the isolation box, and the storage box is used for storing a coating solution; the isolation box is fixed to the rack, and an upper spray head and a lower spray head are arranged in the isolation box; the upper spray head is located on the upper portion of the interior of the isolation box, and a first discharging port of the upper spray head faces downwards; the lower spray head is located on the lower portion of the interior of the isolation box, and a second discharging port of the lower spray head faces upwards; and a communicating pipe is connected between a first feeding port of the upper spray head and a second feeding port of the lower spray head, the middle portion of the communicating pipe communicates with the storage box through a delivery pipe, and the delivery pump is arranged in the delivery pipe. The spraying and drying equipment for the ultrafine aramid fiber needle-punched filter bag has the advantages that multiple functions are achieved, and the product quality is good.

Description

technical field [0001] The invention relates to a spraying and drying equipment for an aramid superfine fiber needle-punched filter bag. Background technique [0002] The rapid development of modern industry has brought many material benefits and social benefits to human beings. At the same time, it has also brought serious harm to the environment on which human beings live, especially in the aspect of large amounts of exhaust gas emissions. In order to protect the environment in which human beings live, it is quite necessary to formulate more stringent air emission standards, promote more advanced and more efficient dust removal technology, reduce industrial dust emissions, and improve the atmospheric environment. The filter bag is a key part in the operation of the bag filter, and the cylindrical filter bag is usually hung vertically in the filter bag. In the existing dust collector, the dust is attached to the outer surface of the filter bag. When the dusty gas passes th...
