Description

A single-roll opening machine for regenerated fiber of waste textiles

【Technical field】

The utility model relates to recycling processing equipment for waste and old textiles, in particular to a regenerated fiber opener for waste and old textiles.

【Background technique】

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 amount of carbon dioxide and other emissions, causing environmental pollution and waste of resources. However, the recycling rate of waste textiles in western developed countries has reached over 16%, and various measures are being adopted to further increase the comprehensive utilization rate.

At present, the technology and equipment of my country's regenerated fiber industry are backward, high energy consumption per unit output value, serious environmental pollution, and many safety hazards in the production process. The traditional domestic regenerated fiber recycling process is as follows:

Recycling quality of cloth scraps from waste textiles and garment factories→cutting by rag machine→opening machine→bomb cleaning machine→packing machine

Among them, the opening machine plays a role of connecting the past and the future in the processing flow.

Existing opening machine is shown in Figure 1, waste and old textiles are directly conveyed to feeding roller 35, miscellaneous plate 36 and opening roller 37 through cotton feeding inclined curtain 33 after being cut by rag machine, and the fiber after opening enters Dust cage 38, wherein the linters and dust are discharged into the atmosphere by the dust exhaust fan 40 through the dust exhaust pipe 43, and the loose cotton layer enters the nodding hopper 39, and then is discharged by the cotton suction fan 41 and the discharge mesh pipe 45 and The export conveyor flat curtain 46 is sent to the bomb cleaning machine 47, and the excess cotton layer is sucked back by the cotton blower 42 and then falls on the cotton input curtain 33 through the cotton return pipe 44 and the dust filter 34, and then enters the opening process. In the process, the cotton conveying flat curtain 31, the export conveying flat curtain 46, the cotton conveying oblique curtain 33, the cotton conveying oblique curtain 32 and the secondary dust filter 34 are recovered, and the primary dust cage 38 is open, and all parts are fixed on the Rack 48. 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:

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 large, there are potential safety hazards, and occupational diseases are prone to occur, and operators are reluctant to engage in this kind of work. Moreover, the failure rate is high and the maintenance cost is relatively large.

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 process, dust will fly in the workplace, which will seriously pollute the surrounding environment and affect the health of the operator.

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

【Content of utility model】

In order to meet the domestic market demand for the recycling of waste textiles, the applicant has developed a single-roller opener for regenerated fibers of waste textiles, which is a special equipment for fiber opening in the recycling process of waste textiles.

The technical scheme that the utility model takes is as follows:

A single-roll opening machine for regenerated fibers of waste textiles, characterized in that it includes a cotton inlet, a multi-functional miscellaneous removal box, a cotton inlet fan, a double-round dust cage filter cartridge, a dust velvet chamber, a cotton storage box, and a star roller , front and rear steel rollers, adjustable dust grid, opening roller, cotton return tube, cotton outlet, heavy dust removal bar, magnet, heavy waste box, cotton return hopper and dust filter interface, cotton inlet is multi-functional dust removal The inlet of the cotton box, the cotton suction port of the cotton inlet fan is connected with the outlet of the multi-functional dust removal box, the cotton outlet of the cotton inlet fan is connected with the inner cavity of the double-round dust cage filter cartridge, and the dust velvet chamber is located in the double-round dust cage filter. Outside the cylinder, the dust lint cavity is input into the dust filter through the dust filter interface. The cotton storage box is located between the double-round dust cage filter cylinder and the star rollers. The front and rear steel rollers are set between the star rollers and the opening rollers. The dust grid can be adjusted. It is set on the lower right of the opening roller, and the cotton return hopper is set under the opening roller and the adjustable dust grid. The outlet of the cotton return hopper is connected with the cotton return pipe, and the outlet of the cotton return pipe is connected with the multi-functional miscellaneous removal box. The heavy dust removal rod is set at the bottom of the multi-functional dust removal box, and forms an angle of 30°~75° with the horizontal axis of the cotton inlet. The magnet is set on the lower side of the heavy dust removal rod, and the heavy dust box is set on the Below the heavy dust removal rod, the cotton outlet is vertically set on the left side of the opening roller, and the center line of the cotton outlet is tangent to the outer circle of the opening roller.

Further, the heavy dust removal rod forms an included angle of 45°~60° with the horizontal axis of the cotton inlet.

Its working process is as follows:

After the waste textiles are cut by the rag machine, soaked in water, bleached and dried, under the action of the cotton inlet fan, they directly enter the multi-functional dust removal box from the cotton inlet. The raw materials collide with the heavy dust removal rod, and due to inertia, After impacting the heavy dust removal rods, some heavy impurities pass through the gap between the heavy dust removal rods and are discharged into the heavy dust bin. At the same time, the metal in the raw material is also absorbed by the magnet. The raw material enters the double-round dust cage filter cartridge from the multi-functional miscellaneous removal box through the cotton inlet fan. After the fleece cavity is sucked away by the dust filter through the interface of the dust filter, the raw materials fall into the cotton storage box after the pressure is released. Since the double-cylindrical dust cage filter cartridge is a double-cylindrical dust cage, it has a larger exhaust area than the traditional single-cylindrical dust cage, which is not only conducive to the dust removal of raw materials, but also improves the uniformity of raw materials falling into the cotton storage box. , is beneficial to the feeding of cotton.

The raw materials falling into the cotton storage box are fed into the beating room after passing through the star rollers and the front and rear steel rollers. The direction of rotation is transferred in the beater room, and the cotton is stripped off by the stripping knife, and enters the next machine through the cotton outlet; the opening roller adopts a metal cylinder structure, and the cylinder is covered with metal card clothing, which has a good opening effect and is not easy to loosen. damage; the dust grid mechanism adopts the structure of dust removal knife and triangular dust rod, which can be adjusted manually according to the requirements of raw material conditions, noil rate and cotton opening degree, so as to achieve the best use effect.

Under the action of the opening roller, the raw material is gradually torn and loosened. At this time, under the impact of the opening roller, a small part of the raw material directly falls into the cotton return hopper through the adjustable dust grid, and is sucked by the cotton inlet fan. , this part of the raw material enters the multi-functional miscellaneous removal box again through the cotton return pipe, and is mixed with the incoming cotton raw material before being fed into the cotton box for secondary opening treatment.

Because the utility model adopts a closed frame structure, the dust and short fluff entering the dust velvet cavity from the mesh on the double-round dust cage filter cartridge directly enter the dust filter unit for processing through the dust filter interface, and the main engine always maintains negative pressure operation, No dust and lint leak out of the machine to pollute the environment and affect health.

It has been verified by actual use that the average length of the fibers after opening can reach more than 14mm, which greatly improves the utilization rate of raw materials, and the output is 400-500kg/h. The installed power of the whole machine is only 16.5kW, and the energy consumption is only half of that of traditional opening machines. , it has small size, low power consumption, high output, no dust and short fleece, and low noise.
