Description

one

The invention relates to textile industry and can be used to clean raw cotton.

The purpose of the invention is to increase the reliability of the work by reducing the amount of wastes being discarded.

FIG. 1 schematically depicts a cleaner; in fig. 2 - scheme of the impact of raw cotton sheaves with working bodies.

The raw spill cleaner contains the sawed drum 1 and a pair of stringing brushes 2 and 3 arranged sequentially around it in rotation for the rotation of a pair of stringing brushes 2 and 3 and a grate consisting of sections 4 and 5 separated by a pressure roller 6 of elastic material. The grate bars in each section of the grid are mounted relative to the drum surface with a variable clearance A, increasing in the direction of rotation of the drum in the first half of the section and decreasing in the same direction in its second half. The working surface of the second stringing brush 3 is inclined to the surface of the drum, and the brush 3 itself is installed with the possibility of changing the angle o.

When the cleaner is working, raw cotton is supplied to the surface of the serrate drum 1, captured by its teeth and fixed to them with the help of a fixed tapping brush 2, it is encountered with an additional brush.

3, which enhances the bond between the wire and the surface of the drum.

The cleaning of raw cotton occurs due to the impact of the pellets on the nursery, set in each section 4 and 5 of the grate, taking into account the stretching of the bat, with unequal clearance relative to the drum surface. The pressure roller b again hooks the weakened flyers. When the grate's impact on the raw cotton is aggravated by a shaking effect, the link between the batters and the litter is broken, resulting in weedy

impurities under the action of centrifugal forces and the forces of gravity fall out through the gaps between the grate bars.

The necessity of settling the grates at unequal distances from the drum surface is due to the fact that the trajectory of the center of mass of the wheel attached to the teeth of the drum is due to the elasticity of the latter and its stretchability under the action of centrifugal forces, it is an arc of a circle, located at an unequal distance from the drum surface, smaller at the ends of the grate and larger at its middle. The arrangement of the grate along the indicated curve (close to the parabola) eliminates the possible exit of the center of mass of the bat outside the lattice (Fig. 2). This means it reduces the departure of the volatile material to waste.
