Embodiment 1

[0019] see Figure 1-3 As shown, an antistatic polyester needle-punched felt includes a needle-punched felt 1 and a sealing layer 2, one end of the needle-punched felt 1 is connected with a sealing layer 2, and one side of the inner side of the needle-punched felt 1 is connected with a buffer layer 3, and the buffer layer 3 One side is connected with a filter layer 5, one side of the filter layer 5 is connected with a first polyester layer 4, one side of the first polyester layer 4 is connected with a second polyester layer 7, and one side of the second polyester layer 7 is connected with a wear-resistant layer 8. The polyester layer during work can eliminate the static electricity generated by the needle felt 1 during use, and the static electricity will not affect the normal filtration. And the tensile layer 6 increases the toughness of the needle felt 1, the needle felt 1 is not easily damaged, the buffer layer 3 increases the cushioning performance of the needle felt 1 dur...

Embodiment 2

[0021] Additionally, according to Figure 1-3 As shown, the difference between it and the above embodiment is that a stretch layer 6 is connected between the first polyester layer 4 and the second polyester layer 7, and the stretch layer 6 increases the tensile capacity of the needle felt 1, and the needle felt 1 Not easy to damage. The depth of the groove body 10 is greater than that of the groove 9 , and the groove 9 can be arranged inside the groove body 10 to increase the surface area of ​​the groove body 10 . Several grooves 9 are evenly arranged inside the tank body 10, the surface area inside the tank body 10 is increased, and the filtering efficiency is improved. The interior of the buffer layer 3 is arranged in a honeycomb shape, and the arrangement of the honeycomb shape makes the buffer layer 3 better in buffering capacity and improved in stability.

[0022] When the present invention is in use, at first, the feeding pipe 4 is connected with the external feeding m...

Abstract

The invention discloses antistatic polyester needle-punched felt which comprises needle-punched felt, a sealing layer, a cushion layer, a first polyester layer, a filter screen layer, a stretching layer, a second polyester layer, an abrasion-resistant layer, grooves and a groove body. The antistatic polyester needle-punched felt has the advantages that static electricity generated by the needle-punched felt during use can be eliminated by the polyester layers when the antistatic polyester needle-punched felt works, and accordingly normal filter can be prevented from being affected by the static electricity; the tenacity of the needle-punched felt can be improved by the stretching layer, accordingly, the needle-punched felt is difficult to damage and is good in safety performance, and the service life can be prolonged; the cushion performance of the needle-punched felt can be improved by the cushion layer during work, accordingly, the antistatic polyester needle-punched felt is good instability performance, and shaking can be prevented; the external area of the abrasion-resistant layer can be increased during work, to-be-filtered substances are fed into the grooves and the groove body when in contact with the abrasion-resistant layer, accordingly, the filter efficiency can be improved, and the antistatic polyester needle-punched felt is speedy and is high in efficiency; the tensile resistance of the needle-punched felt can be improved by the grooves and the groove body, and accordingly the needle-punched felt is difficult to break and damage.

Description

technical field [0001] The invention relates to a needle-punched felt, in particular to an antistatic polyester needle-punched felt, which belongs to the application field of needle-punched felts. Background technique [0002] Polyester needle-punched felt series filter materials are made of non-woven needle-punched technology, and are made by heat setting and other treatment methods. They are widely used in industrial dust collection and smoke control. The polyester needle felt filter material has good air permeability, and after heat treatment, the surface is flat and smooth, not easy to deform, and easy to clean. The polyester needle felt filter material after hydrophobic and oil-repellent treatment has hydrophobic properties, and when it is used in smoke with high moisture content or a small amount of oil, it can prevent the bag from sticking and prolong the service life. [0003] But existing polyester needle felts still have certain deficiencies in use. The existing ...
