Description
Technical Field
[0001] The utility model relates to the technical field of polyester cloth bags, in particular to an antistatic polyester cloth bag. Background Art
[0002] Polyester bags are made of high-quality fine-denier chemical fiber yarns, and polyester (polyester) fiber needle-punched filter felts are produced with advanced equipment. Multiple fibers can be evenly and quantitatively mixed, and then multiple mixed cotton opening units and carding units are used to facilitate the interlayer compounding and gradient transformation of different fibers between the fiber webs. Polyester bags have the advantages of high porosity, good air permeability, high dust collection efficiency, and long service life that are unique to ordinary felt filter cloths. Because of its moderate temperature resistance, which can reach 150°C instantly, moderate acid and alkali resistance, and very good wear resistance, it is a variety of felt filter materials with a large amount of use. In the production process of petrochemical enterprises, industrial gas dust removal such as air and nitrogen is often one of its indispensable links. In order to remove impurities in the air, such as production medium dust, to meet qualified recycling or emission standards, and to avoid electrostatic discharge caused by surface accumulation of charges during filter bag filtration, flash fire and other accidents, the use of anti-static polyester bags has always been a key step in gas dust removal in most petrochemical enterprises.
[0003] The patent document with the prior art publication number CN210455747U provides an antistatic polyester bag, which relates to the field of environmental protection, including a bag body, a base fabric layer, a corrosion-resistant layer at the bottom of the base fabric layer, a first antistatic layer at the top of the base fabric layer, a flax fiber layer between the first antistatic layer and the second antistatic layer, a fixing ring at the top of the bag body, a support portion at the bottom of the bag body, the top of the support portion is connected to the bottom of the bag body, a first through hole is provided on the inner side wall of the support portion, a support ring is provided inside the support portion, a connecting shell is provided at one end of the support ring, a connecting block is provided at the other end, the connecting block is inserted into the connecting shell and connected with the connecting shell, a second through hole is provided on the inner side wall of the support ring that is recessed inside the support ring, a pull block is provided inside the second through hole, the pull block includes a pull plate, the bottom of the side wall of one end of the pull plate is connected to one end of the card plate, the other end of the card plate is connected to one end of the baffle, and the baffle is connected with the inner side wall of the support ring by carding. The utility model has good antistatic effect and stability.
[0004] However, during the use of the existing anti-static polyester cloth bag, the gas contains oxygen, nitrogen, trace gases, floating dust, impurities, etc., and these substances will produce friction, which will generate static electricity. In order to avoid safety accidents caused by static electricity, static electricity materials are used for anti-static purposes. However, the static electricity generated by impurities in the gas cannot be eliminated, resulting in poor anti-static effect of the polyester cloth bag. For this reason, we propose an anti-static polyester cloth bag. Utility Model Content
