Single-roller opener for regenerated fibers of waste textiles

Abstract

The invention provides a single-roller opener for regenerated fibers of waste textiles. The single-roller opener comprises a cotton inlet, a multifunctional impurity removing box, a cotton inlet fan, a double-circle dust cage filter drum, a dust flock cavity, a cotton storage box, a star-like roller, front and back steel rollers, an adjustable dust grid, an opening roller, a cotton return pipe, a cotton outlet, a heavy impurity removing grid bar, a magnet, a heavy impurity box, a cotton return hopper and a dust filter port, wherein raw materials directly enter the multifunctional impurity removing box from the cotton inlet under an effect of the cotton inlet fan; first, the raw materials are collided with the heavy impurity removing grid bar, so as to remove heavy impurities, and metals and then enter the double-circle dust cage filter drum; dust and flocks are sucked by a dust filter of the system; after the pressure of the raw materials is released, the raw materials fall into the cotton storage box, are opened by the star-like roller, the front and back steel rollers as well as the opening roller, and are gradually torn and opened into fiber-shaped substances; average lengths of the opened fibers can reach more than 14 mm; the yield is 400-500 kg/h; and the installed power of the whole machine is only 16.5 kw; and the single-roller opener for the regenerated fibers of the waste textiles, provided by the invention, has the advantages of small volume, small power consumption, high yield, no dust and flock leakage as well as low noise.

Description

【Technical field】 [0001] The invention relates to a waste and old textile recycling processing equipment, in particular to a waste and old textile regenerated fiber opener. 【Background technique】 [0002] my country is a big producer of textiles, but also a big country of users. With the development of science and technology economy and the improvement of people's material level, the application fields of textiles are gradually expanding, and the service life is shortening. Most textiles will become textiles in a few years. Waste and old textiles, at present, domestic waste and old textiles have not been well utilized, our country's understanding of waste and old textile recycling is not deep, and the research work on waste and old textile recycling has just started, and the comprehensive utilization rate of waste and old textiles is insufficient. 0.1%. Now the most common treatment method is incineration. Incineration not only consumes energy, but also produces a large amoun...

[0002] my country is a big producer of textiles, but also a big country of users. With the development of science and technology and the improvement of people's material level, the application fields of textiles are gradually expanding, and the service life is shortening. Most textiles will become textiles in a few years. Waste and old textiles, at present, domestic waste and old textiles have not been well utilized, my country's understanding of the recycling of waste and old textiles is not deep, and the research work on the recycling of waste and old textiles has just started, and the comprehensive utilization rate of waste and old textiles is insufficient. 0.1%

Through structural analysis, it can be seen that this kind of opener has a large volume and a long process. Three open cotton conveying curtains, a single-layer dust cage and a pipeline-type conveying structure will inevitably lead to large noise pollution and dust pollution, high energy consumption, and low production efficiency. , this kind of opener technology is relatively backward, the specific analysis is as follows:

[0007] ①The equipment technology is backward, and the design and production of the main parts are too primitive, simple and rough. For example, the opening roller is made of wooden cylinder. The noise is loud, there are potential safety hazards, and it is easy to cause occupational diseases. Operators are reluctant to engage in this kind of work

Moreover, the failure rate is high and the maintenance cost is relatively high

[0008] ② The closed state of the opener is not good, the mixed material is fed to the feeding conveying curtain, and is directly exposed to the air, and there is no dust removal system in the process, and the dust and short fibers are directly diffused into the air without treatment during the working process In the middle, the dust in the workplace will fly, seriously pollute the surrounding environment and affect the health of the operator

[0009] ③The equipment has high energy consumption and low efficiency. The installed power of the opening machine (excluding the power of the pipeline treatment fan) is as high as 30kW, and the transmission efficiency and opening efficiency are low, and the output is only 200-300kg / h
