Abstract

The utility model relates to a raw cotton impurity removing device which comprises a U-shaped passage with the section in a rectangle shape, one end of the U-shaped passage is a raw cotton inlet, the other end is a raw cotton outlet, the outer arc surface of the lower side of the U-shaped passage is provided with an opening, the lateral walls of the U-shaped passage positioning at both sides of the opening are respectively fixedly provided with an arc-shaped dust removing bar stand, a plurality of dust removing bars are fixedly arrayed between the two arc-shaped dust removing bar stands, and a guide plate which tilts towards the inner part of the U-shaped passage is arranged on an inner arc surface positioned between the raw cotton inlet inside the U-shaped passage and the opening. The raw cotton impurity removing device utilizes air flows to enable the raw cotton to freely bump the dust removing bars when passing through the U-shaped passage of the raw cotton impurity removing device to achieve the purpose of impurity removal, thereby reducing the injury on raw cotton fibres by holding bump for impurity removal and enhancing the impurity removing efficiency. The raw cotton impurity removing device can not only independently carry out impurity removal, but also carry out impurity removal with a blowing integral unit together so as to enhance the impurity removing effect of the prior blowing integral unit.

Description

The raw cotton knot screen

(1) technical field:

The utility model relates to textile processing machine, is specifically related to a kind of raw cotton knot screen.

(2) background technology:

Owing to exist a large amount of impurity in the raw cotton of purchase, cotton spinning enterprise must remove the impurity in the raw cotton before spinning, just can carry out slubbing and spinning then, otherwise can influence the quality of resultant yarn.The blowing equipment of existing textile enterprise mainly is that the method for taking to grip strike is carried out removal of impurities, this impurity-removing method generally can only be removed the bigger impurity in the raw cotton, to still existing more tiny granule foreign in the raw cotton, the fiber generation certain damage of removal of impurities meeting to raw cotton hit in excessive gripping, thereby influence the quality and the single end strength of resultant yarn, the fine impurities of therefore removing under the situation that does not injure raw cotton fiber in the raw cotton plays crucial effects to the quality of resultant yarn.

(3) summary of the invention:

The purpose of this utility model be to provide a kind of simple in structure, cost is low, the raw cotton knot screen of good impurity removing effect.

For achieving the above object, raw cotton knot screen described in the utility model comprises that a section is rectangular U-shaped passage, and described U-shaped passage one end is the raw cotton import, and the other end is the raw cotton outlet; The extrados of U-shaped passage below is provided with an opening, the channel side wall lower edge of opening both sides is fixed with the dust removing bar frame of arc respectively, alternate stationary arrangement has several dust removing bars between two dust removing bar framves, and the raw cotton import in the U-shaped passage is provided with the guide plate that tilts to the intrados between the opening in passage.

Described U-shaped passage is installed in the upper shed of disposal box that upper and lower is opening and with the upper shed of disposal box and matches, disposal box is a box body, be respectively equipped with slot on the two side of the lower opening correspondence of disposal box, another sidewall is provided with jack, and base plate passes jack and inserts in the slot.

The sidewall of described disposal box is provided with the observation window of being made by transparent material.

The sidewall of described U-shaped passage is provided with the peep hole of being made by transparent material.

The section of described dust removing bar is a triangle.

Owing to adopted technique scheme, raw cotton knot screen described in the utility model is to utilize air-flow to make raw cotton carry out freely clashing into when the U-shaped passage by the raw cotton knot screen and between the dust removing bar, make the fine particle impurity in the raw cotton fall into disposal box by the gap between dust removing bar, reduced and gripped the damage of the method removal of impurities of strike raw cotton fiber, improve dust removal rate, and and then improved the quality of resultant yarn.

(4) description of drawings:

Fig. 1 is a raw cotton knot screen structural representation described in the utility model;

Fig. 2 is the longitudinal sectional view of raw cotton knot screen shown in Figure 1.

(5) specific embodiment:

By Fig. 1, Fig. 2 as seen, raw cotton knot screen described in the utility model comprises that a section is rectangular U-shaped passage 1, U-shaped passage 1 is installed in the upper shed of disposal box 8 that upper and lower is opening and with the upper shed of disposal box 8 and matches, disposal box 8 is a box body, be respectively equipped with slot on the two side of the lower opening correspondence of disposal box 8, another sidewall is provided with jack, base plate 9 passes jack and inserts in the slot, disposal box 8 main purposes are to be convenient to collect impurity, dust, prevent impurity, other raw cotton of contamination by dust; Described U-shaped passage 1 one ends are raw cotton import 2, and the other end is raw cotton outlet 3; The extrados of U-shaped passage 1 below is provided with an opening 4, the channel side wall lower edge of opening 4 both sides is fixed with the dust removing bar frame 5 of arc respectively, alternate stationary arrangement has several dust removing bars 6 between two dust removing bar framves 5, promptly dust removing bar 6 alternately is arranged on opening 4 places on the extrados of U-shaped passage 1 below just, dust removing bar 6 is generally flat strip shaped, and preferably selecting section is triangle; Raw cotton import 2 in U-shaped passage 1 is provided with the guide plate 7 that tilts to the intrados between the opening 4 in passage, guide plate 7 is the raw cotton that will enter U-shaped passage 1 from raw cotton import 2 dust removing bars 6 that lead as far as possible, increase the collision probability between raw cotton and the dust removing bar 6, improve impurity-eliminating effect.The situation of collecting impurity, dust for the removal of impurities working condition of observing the raw cotton knot screen and disposal box 8, be convenient in time to the raw cotton knot screen keep in repair with disposal box in impurity remove, on the sidewall of described U-shaped passage 1, be provided with the peep hole of making by transparent material 11.On the sidewall of described disposal box 8, also be provided with the observation window of making by transparent material 10, but setting operation window also on the sidewall of disposal box 8 is convenient to the raw cotton knot screen is keeped in repair.

During work, the raw cotton that will contain impurity by blower fan is blown into the U-shaped passage 1 of raw cotton knot screen from the raw cotton import 2 of U-shaped passage 1 one ends, under the guiding of guide plate 7, freely clash into the dust removing bar 6 at extrados opening 4 places of U-shaped passage 1, by and dust removing bar 6 between multiple impact in, fine particle impurity such as the impurity in the raw cotton, dust break away from the gap of raw cotton between dust removing bar 6 and fall into disposal box 8, former cotton-wadded quilt blower fan behind the removal of contamination blows out from the raw cotton outlet 3 of U-shaped passage 1 other end, has reached the purpose of removing impurity in the raw cotton.

Raw cotton knot screen described in the utility model both can utilize blower fan that raw cotton is blown into independently to carry out removal of impurities work in the raw cotton knot screen, also it can be installed between the mixing and blowing machine and multi-mixer of existing blowing associating unit, as blowing associating unit part of work, utilize the airflow of defeated cotton blower fan to carry out removal of impurities work, can improve the impurity-eliminating effect of existing blowing associating unit greatly.
