(54) DRUM FOR CLEANING FIBER MATERIAL

The invention relates to the textile industry and can be used to clean fibrous materials. According to the main author. swith 267197 a drum is known for cleaning the fiber of that material, which contains alternating rows of jogs and blades located along its forming, set obliquely to the axis of the drum, with the blades in adjacent rows having the opposite direction, the disadvantage of this drum being - due to the insignificant number of successful interactions of the pegs and blades along the transported material due to its high rate of advancement along the cleaning surface. The aim of the invention is to increase the cleaning effect by reducing the rate of advance of the material along the cleaning surface. . This goal is achieved by the fact that the pegs and blades have a wave-like profile. FIG. 1 noKasasr general view of the drum; in fig. 2 is a diagram of the interaction of the working part of the splitting with the material (raw cotton sheaves). The drum for cleaning fibrous material consists of flanges 1 mounted on shaft 2, shell 3, on which are located rows of splits 4, made in the form of a circular wave-like profile. Between the rows of pegs 4 are strips 5, made in the form of an extended base (for example, strips), on which are installed with a definition bar. This is an oblique angle to the axis of the drum, the blade 6. Moreover, each blade has a wavy (periodically curved) profile. The blades 6 in adjacent rows (slats) have the opposite direction. The fibrous material (raw cotton) comes from under the feed rollers (not shown), is picked up by the rollers 4, which is rotating and moves along the grid (not shown). Since the speed of movement of the fibrous material on the grid is less than the speed of the drum, the material periodically falls under the shock effects of the spikes and blades, as a result of which weed impurities are separated and output into the grid cells.

In the interaction of the wave-like profile of the krlkov 4, the material deepens in the hollows of the pegs, and their repetition is also a blow in this case. an elastic-plastic nature (cotton properties), then part of the energy for acquiring a significant rebound rate of cotton (volley) from splitting 4 is spent on changing the forka material, la (here the splitting form absorbs the speed of the rebound). As a result, the speed of advancement of the product along the tick is reduced due to the fact that it is subjected to a greater number of shock effects On the side of Kolkov 4 and the blades 6 of the rotating drum.

Periodically curved blades during rotation of the drum interact with the compacted beard of the material coming out from under the feed rollers.

preliminarily dissected the material barb within the limits of the bend size, and then, due to the impact, separates it from the total mass produced by the feed rollers of the product. This phased process of preliminary dividing such a profile will increase the cleaning effect and reduce the percentage of crushed seeds.
