Simple liquid squeezing device

Abstract

The invention discloses a simple liquid squeezing device, which is composed of U-shaped clamping slots, fixed rods, floating rods, regulating screw rods, nuts, rubber sleeves, U-shaped clamping plates and a liquid receiving tank. The simple liquid squeezing device is provided with a group of fixed rods and floating rods in staggered arrangement, each floating rod is located between two adjacent fixed rods, and the lower edge position of each floating rod is lower than the upper edge position of the corresponding fixed rod. The fixed rods and the floating rods are both cylinders with two square end parts, the square end parts are matched with openings of the U-shaped clamping slots and U-shaped clamping plates in size. The simple liquid squeezing device disclosed by the invention has the advantages of no power consumption, simple structure, low manufacture cost and good liquid squeezing effect.

Description

Technical field [0001] The invention relates to a liquid squeezing device for wet tow in the field of textile machinery. The device is specifically applied to removing most of the spinning liquid in the tow before neutralizing and washing in the production of high-strength and high-modulus polyvinyl alcohol (PVA) fibers. Background technique [0002] At present, in the production process of high-strength and high-modulus polyvinyl alcohol fibers (PVA), the tows ejected from the tile-shaped spinneret are solidified and formed by the spinning bath liquid, and then preliminary drafted to obtain a total denier of 100,000 to 300,000 deniers. flaky tow. Since the spinning bath is a sodium sulfate solution added with dilute sulfuric acid, in the subsequent neutralization and washing process, the acidic bath brought out from the spinning bath in the tow must be neutralized with sodium hydroxide solution before Clean up. There are two problems like this: one is because the water co...

AI Technical Summary

Problems solved by technology

There are two problems like this: one is because the water content of the tow is relatively large, generally the water content of the tow coming out of the bath can reach 200%. In order to neutralize the acid in the bath, a large amount of hydrogen oxidizer needs to be consumed. At the same time, in order to wash the neutralized product sodium sulfate, a large amount of constant temperature washing water is consumed, which consumes resources and produces three wastes

The more bath fluid the tow takes away, the greater the replenishment, and the higher the cost of the line operation
