SU44498A1 - Weave Purifier for Spinning Fibers - Google Patents

Description

The use of tops in the spinning factories to clean the scutching and carcass nuts and the like is of great interest, since it frees the transport from the need to transport impurities that do not have direct value.

The present invention, relating to a dedusting spinners for spinning fibers, consisting of a shaft with beams, passing between the fingers fixed on a fixed cylindrical casing, aims to give a simple top to the design that can be performed by any factory mechanic in a waste factory. In size, this top requires space, several times smaller than imported tops. In order to solve the problem, the proposed top has a series of partitions of various sizes, which are suspended between the fixed fingers of the casing and serve to eliminate the rolling of the fiber. A fan is installed on the blade shaft, pulling the fiber along the axis of the drum.

In FIG. Figures 1 and 2 depict a general view of a dedusting top (in two projections).

On the horizontal shaft / in the radial direction, they are fixed in the bearing 9, beating 2 at an angle of 36 to one another along a helical line. Bile 2, in its motion, passes between the fixed fingers 8 of the casing 4 installed in the wooden frame. The lower half of the cylindrical casing 4, inside of which the shaft / with the beams 2 is enclosed, is a wire mesh 3 of the weaving weave, and the upper deaf flap with a loading bucket 5 equipped with a slide for controlling the speed of air movement.

Partitions 13 suspended between rotating beams are suspended from the casing, the width of these partitions (in the radial direction) alternately increasing or decreasing. Due to such a device, the free section, and therefore the velocity of the air passing through the material, varies, which is meant to eliminate rolling up of the fiber.

A two-bladed fan 77 is mounted on the shaft end / mounted. The cylindrical casing 4 is connected to the chamber 10 for collecting the cleaned product by means of a pipe 7.

The work of the top is as follows. The waste to be cleaned is applied to the tray, from where through the loading bucket. get into drum 4. Here the material is subjected

The impact was hit 2, the weed impurities falling through the openings of the mesh 5 into the chamber 6, from where they are removed as they are filled through the door in the front wall. Due to the helical arrangement of the blows and the action of the fan, the material to be processed is advanced and through pipe 7 enters the chamber Yu, from where it is filled and removed when filled. The fixed fingers 8, as well as the suspended partitions 13, contribute to a better cleaning and prevent the fibers from being rolled into bundles. With a shaft speed of 600 rpm, the performance of the top, according to the author, reaches 350 kg in 7 hours. Normal elimination is 30%. By changing the grid 3 to a rarer or frequent, the degree of screening can be changed.

The subject matter of the invention.

A chopper for spinning fibers consisting of a shaft with beams extending between fortified fingers on a stationary cylindrical case, characterized by the use of partitions 13 of various sizes suspended from case 4 between stationary fingers 8 and intended to prevent rolling of the fiber pulled along the axis of the drum fan mounted on the mobile shaft.
