Directional-cotton-feeding tiny-dust lateral-discharging structure of tiny-dust removing machine

Abstract

The invention discloses a directional-cotton-feeding tiny-dust lateral-discharging structure of a tiny-dust removing machine. The size of a cotton spraying opening is smaller than or equal to the inner diameter of an inner cotton spraying pipe, the arranged position of the cotton spraying opening is located in the center of the length of an arc-surface dust discharging net plate in the horizontal direction, a hole-free smooth area is arranged at the portion, opposite to the cotton spraying opening, of the arc-surface dust discharging net plate, a tiny-dust removing area is arranged at the portions besides the hole-free smooth area, and dust removing holes are evenly formed in the tiny-dust removing area. Cotton flow is directionally sprayed out from the cotton spraying opening, impacts the hole-free smooth area, can not be sucked by the negative pressure generated by a dust discharging draught fan and can be impacted to be reversely and elastically thrown, and further opening is achieved; in the process, the further-opened cotton flow is sucked and reversely and laterally moves by the tiny-dust removing area under the effect of dust removing negative-pressure suction force generated by the dust discharging draught fan, cotton fibers can be further opened accordingly, the falling movement time and the falling path of the cotton fibers are prolonged, and separation of the cotton fibers from tiny dust is better facilitated. According to the test, the removing rate of the tiny dust in the cotton fibers is higher than 92%, and the removing rate in the prior art is only 50%.

Description

Technical field: [0001] The invention relates to a textile dedusting mechanical device, in particular to a dedusting machine for removing fine dust in cotton or other fibers. Background technique: [0002] The dust remover is a high-end textile dust removal equipment used to remove fine dust and impurities in cotton or other fibers. The structure of the existing dust remover is as follows: figure 1 As shown, it consists of an external cotton inlet pipe 1, a cotton feeding fan 2, an inner spraying cotton pipe 3, a cotton spraying port 4, a cotton dust separation chamber 5, an arc-shaped dust discharge screen 6, a cotton suction fan 7, and a cotton outlet Pipe 8, miscellaneous discharge chamber 9 and dust exhaust fan 10, wherein, the cotton inlet pipe 1 and the inner spray cotton pipe 3 are respectively connected to the inlet and outlet of the cotton sending fan 2, and the cotton spray port 4 of the inner spray cotton pipe 3 is set There is a cotton flow swing mechanism, and ...

AI Technical Summary

Problems solved by technology

In the actual use process, the dust removal effect is not ideal. From the design principle, after the cotton flow containing fine dust is sprayed from the cotton spray port 4 of the inner spray cotton pipe 3, the cotton flow collides with the arc-shaped dust discharge screen 6 Finally, the cotton flow will be smashed and thrown up, so that the cotton flow can be fully loosened in the cotton dust separation chamber 5, and the separation of cotton dust can be realized. When it hits the curved surface dust-exhausting screen 6 at a specific speed, under the negative pressure formed by the dust-exhausting fan 10, the cotton flow cannot be effectively scattered and thrown up, and most of the cotton flow is absorbed on the curved-surface dust-exhausting screen 6, the cotton flow is not fully loosened in the cotton dust separation chamber 5, and the cotton and dust are difficult to separate, so the dust cannot be effectively removed, and the removal rate of the dust is less than 50%. This dust cleaning machine is only theoretical Innovative buying point, the actual cleaning effect is very unsatisfactory, and cannot meet the requirements of high-end textiles for removing impurities from cotton slivers
