Abstract

The invention relates to the production of chemical fibers and improves the operational properties of the device due to the intensification of the dewatering process. The device has means for draining the liquid in the form of a perforated pipe 7 with a groove 8, which are placed inside the shaft 1 coaxially with the latter, as well as a nozzle 4 installed inside the shaft 1 along the chord of the inner surface of its perforated shell. It is directed opposite to the feed direction of the canvas man-made fibers. The channels 6 of the perforated shell are inclined in the direction of the nozzle 4v 2 ort. I (L

Description

The invention relates to the production and processing of chemical fibers in the form of canvases, namely to equipment for removing moisture by squeezing rollers.

The aim of the invention is to improve the performance properties by intensifying the maintenance process.

FIG. device shown, section; figure 2 - spin zone.

A device for squeezing the canvas of chemical fibers contains two hollow shafts 1 and 2 arranged one above the other with perforated shells, and inside the upper hollow shaft 1, in the zone of maximum approach of the shafts, a pneumatic chamber 3 is installed, which houses a nozzle 4 directed towards the smallest possible angle. And to the last. The channels 6 of the perforation of the shell of the upper hollow shaft 1 are inclined towards the feed of the canvas 5 chemical fibers at an angle B (to the radius). In addition, inside the upper hollow shaft 1, the perforated tube 7 is coaxially arranged with a groove 8 fixed thereto. The nozzle 4 and the perforated tube 7 with the groove 8 are means for draining the liquid. Pneumatic chamber 3 by means of a pipe 9 is connected with the main pneumatic system (not shown). Under the bottom nojjbiM shaft 2 is a pallet 10.

During operation, the hollow shafts 1 and 2 are rotated, and -. the upper hollow shaft 1 presses against the lower 2 with a predetermined force P. At the same time the canvas 5 delivered between the chemical fibers 5 is pressed. The liquid is partially drained over the lower hollow shaft 2 and through its perforation. A device for squeezing chemical fibers canvas containing two hollow shafts with perforated shells arranged one under the other and a means for draining the liquid inside the upper shaft, about one liter and -. In order to improve operational properties by intensifying the dewatering process, the means for draining the liquid is made in the form of a perforated tube with a groove located coaxially with the shaft and a nozzle mounted along the inner surface of the perforated shell and directed opposite to the feed direction of the canvas of chemical fibers , and channels

the upper hollow shaft 1, and partially through the channels 6 enters the upper hollow shaft 1. Through the pipe 9 into the chamber 3 compressed air is supplied, which, having flowed out of the nozzle 4, blows the fluid through the channels 6 through the channels 6 to the opposite direction the supply of canvas, while part of the liquid through perforation gets before pressing onto the canvas, and part is caught by chute 8 and removed through the perforated pipe 7. In addition, the presence of an acute angle between the flow of compressed air and the direction of the channels 6 of the top floor perforation The first shaft 1 creates an ejection effect, through which the fluid filling the perforation channels 6 is sucked.

The application of the proposed device allows eliminating complex and expensive pneumosuction equipment and intensifying the process of fluid removal.
