Feeding equipment for producing polyethylene fibers

Abstract

The invention discloses feeding equipment for producing polyethylene fibers. The feeding equipment comprises a feeding kettle. A polyethylene powder and solvent mixed liquid input pipeline is connected to the top of the feeding kettle, a polyethylene powder and solvent mixed liquid output pipeline is connected to the bottom of the feeding kettle, and a polyethylene powder and solvent mixed liquid circulating pipeline is further connected to the feeding kettle. The inlet end of the polyethylene powder and solvent mixed liquid circulating pipeline is communicated with the bottom of the feeding kettle, the outlet end of the polyethylene powder and solvent mixed liquid circulating pipeline is communicated with the top of the feeding kettle, and a circulating pump is arranged on the polyethylene powder and solvent mixed liquid circulating pipeline. Compared with an ultrahigh molecular weight polyethylene fiber feeding device used at present, due to the fact that the material circulating pump is added, material accumulation on the bottom in a cavity of a kettle body is avoided, and shearing stress is reduced.

Description

Technical field [0001] The invention relates to a device used in the production of ultra-high molecular weight polyethylene fibers, in particular to a feeding device for the production of polyethylene fibers. Background technique [0002] Ultra-high molecular weight polyethylene fiber, also known as UHMWPE fiber, is a high-tech, high-performance fiber that emerged in the 1990s. It is one of the three high-tech fibers recognized in the world (carbon fiber, aramid fiber, and high-strength high-modulus polyethylene fiber). The fiber has the characteristics of high strength, high modulus, and low density. It plays a pivotal role in offshore oilfield mooring ropes, fishing nets, cages and labor protection, sporting goods, modern warfare and defense equipment, and aviation and aerospace. Therefore, the technological development and application of ultra-high molecular weight polyethylene fibers are of great significance. [0003] In the prior art, to produce ultra-high molecular weight p...

Problems solved by technology

At present, the commonly used liquid level control device is a liquid level gauge. However, because the stirring device installed in the kettle is relatively close to the wall of the kettle, some liquid level gauges (such as float type liquid level gauges, etc.) are not easy to install, and The viscosity of the dissolved liquid in the kettle is high, which makes the use of some liquid level gauges (such as glass tube level gauges, etc.) easy to cause problems such as blockage. In summary, there are certain problems in the use of liquid level gauges in liquid level control.
