Spraying and drying equipment for ultrafine aramid fiber needle-punched filter bag

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...

Problems solved by technology

[0004] Although the filter bag disclosed in this patent is conducive to improving the filtration efficiency of the inner filter layer and can also prolong the service life of the inner filter layer, the filter bag has no corrosion resistance, antistatic and antibacterial properties, and can only be used for simple In the environment, the functionality is poor, and there is no preparation method for the filter bag. Therefore, it is necessary to design a spraying and drying equipment for the aramid microfiber needle-punched filter bag.
