SU1488370A1 - Working drum of raw cotton cleaner - Google Patents

Description

The invention relates to the textile industry and can be used to clean cotton from weed impurities. Invention2

This allows to exclude mechanical damage to the products, to increase the cleaning efficiency, for this purpose, the cotton raw bat is fixed on the working drum and blown in by the air stream. The body of the drum cleaner is made with holes, and two chambers are formed inside the drum, in one of which a vacuum is created, and in the other, an overpressure, and the means for fixing the bullets on the drum are in the form of perforated trapezoidal sections installed with the possibility of radial movement. 1 hp f-ly, 4 ill. at

The invention relates to the textile industry and can be used when cleaning raw cotton from large weed impurities.

The purpose of the invention is to increase the efficiency of cleaning raw cotton while reducing its damage.

Figure 1 presents the working drum, side view; figure 2 is the same, top view; on fig.Z - part of the working drum, side view; figure 4 - part of the drum in the process.

The raw cotton cleaner contains a working drum, perforated shell filings 1, movable strips 2 with longitudinal cuts 3, pegs 4, on which brackets 2 are fixed, restrictive washers 5, endless straps 6, tension rollers / 7, leveling drum 8, chamber

9 vacuum and overpressure chamber 10. The slats on the side faces have an elastic coating 11.

Raw cotton from a shaft (not shown) is fed into the zone of action of the vacuum chamber, where the slats 2 are in the extended position (FIG. 3). Under the action of the chamber 9, the fibers of the fiber are dragged into the slots between the movable bars 2, and with the rotation of the shell 1, the bars 2 approach the zone of action of the endless belts 6 and are pressed against the surface of the drum shell 1, while securing and clamping the fibers of the bars 2 are provided. the drum 8 returns not fixed on the side of the shell in the area of their fastening.

Further, the shells fixed with slats on the side are fed when

rotation to the zone of action of the chamber 10 overpressure. The air jet from the chamber 10 of overpressure, through the holes in the shell and the slits 3 in the slats 2 is sent to the clogged airfoils (Fig. 4) and blows off trash particles from the airfoils, while the airborne particles are kept on the sidewall by closed edges of the wall 2. Design a working drum ensures the cleaning of cotton in the absence of a mechanical effect on the material being cleaned, which prevents its damage.

The width of the plank can be limited to 25 mm so that the air flow acts on the surface of each bat. The fly has a diameter of about 20-22 mm. With a slat width of 25 mm, one (one row) bats are clamped in each gap between the slats. The notches 3 in the slats are along the axis of their symmetry, and therefore the air jet acts on the ϊιοΒβρχΗοοτ of all the voltages clamped in the gaps between the slats.

Formed in the cavity of the drum two cameras - vacuum and high pressure are used to lay the fibers between the slats and the formation of air jets, blowing off trash from the bat of raw cotton, respectively.

The use of a working drum during the cleaning of raw cotton from weed impurities leads to an improvement in the quality of manufactured products by eliminating mechanical damage and

reduce the content of litter.

Claims (2)

Claim 1. The working drum of the cleaner of cotton, containing a drive cylindrical perforated shell, having a suction chamber placed in its cavity and radial strips movably mounted on its surfaces by means of leads, and the drive of their movement, which means that, in order to increase the efficiency of cleaning the cotton · ¹ 'of the raw material while reducing its mechanical damage, it has a discharge chamber placed in the shell cavity, and the slats in cross section are trapezoidal with a smaller base facing the surface of the shell, and have radial holes and elastic coatings on the lateral longitudinal edges, while the leads of the slats are installed with the possibility of their radial movement and have adjustable th limiters of the length of their departure. 2. The working drum according to claim 1, in that the drive of the radial movement of the slats is made in the form of endless drive belts covering the shell on its front sections. 1688370
