Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton powder recycling and reuse technology, and in particular to a feeding device for cotton powder recycling and reuse. Background Technology
[0002] Refined cotton is the main raw material for cellulose production. After being opened by a cotton opener, the refined cotton enters a pulverizer. After pulverization, the powder must be between 60 and 80 mesh to meet the standard. The cotton dust is then separated by a cyclone separator and bagged, while the dust is filtered by a bag filter before being bagged and then metered and stored. However, in practical application, this operation still has shortcomings: First, the powder after the cyclone separator may not meet the standard, requiring the bagged powder to be re-entered into the cyclone separator for secondary separation. Manual bagging is not only time-consuming and labor-intensive, but also requires manual transport of the bagged powder to the pulverizer's feed inlet upstairs, resulting in high labor intensity. Second, the multiple separation processes require continuous manual coordination, leading to low work efficiency and the need for constant monitoring of the powder's mesh size. Third, during the entire bagging process, dust from the powder easily spills out, severely polluting the workshop and posing a significant health hazard to workers. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, this utility model provides a feeding device for cotton dust recycling and reuse. It features a reasonable structural design and convenient operation, replacing manual handling with pipeline transportation, eliminating the need for manual bagging, and effectively recycling the dust. This saves time and labor, reduces the intensity of manual operation, and eliminates the need for frequent monitoring of dust levels, significantly improving work efficiency. It also effectively prevents dust spillage, eliminates pollution to the workshop environment, and protects the health of workers, thus solving the problems existing in existing technologies.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0005] A feeding device for cotton powder recycling includes a cotton opener connected to the feed inlet of a pulverizer via a pipeline, and the discharge outlet of the pulverizer connected to the feed inlet of a cyclone separator via a pipeline. A fan is installed on the pipeline between the pulverizer and the cyclone separator. A first shut-off fan is installed at the discharge outlet at the bottom of the cyclone separator and is connected to a cotton hopper via a pipeline. The air outlet of the cyclone separator is connected to the feed inlet of a bag filter via a pipeline. A second shut-off fan is installed at the discharge outlet at the bottom of the bag filter and is connected to the pipeline between the pulverizer and the fan via a connecting pipeline.
[0006] Optionally, the connecting pipeline includes a distribution pipe connected to the second blower, the lower end of which is connected to the guide pipe, and the outer end of which is connected to the pipeline between the crusher and the blower; a butterfly valve is provided on the guide pipe near the blower.
[0007] Optionally, an observation window is provided on the distribution pipe below the second-stage blower.
[0008] Optionally, the bag filter has two sets of outlets, and the distribution pipes on each of the second blowers are respectively connected to the guide pipes.

[0016] As shown in the figure, in this embodiment, a feeding device for cotton powder recycling includes a cotton opener 1. The cotton opener 1 is connected to the feed inlet of a crusher 2 via a pipeline. The discharge outlet of the crusher 2 is connected to the feed inlet of a cyclone separator 3 via a pipeline. A fan 4 is installed on the pipeline between the crusher 2 and the cyclone separator 3. A first shut-off fan 5 is installed at the discharge outlet at the bottom of the cyclone separator 3. The first shut-off fan 5 is connected to a cotton hopper 6 via a pipeline. The air outlet of the cyclone separator 3 is connected to the feed inlet of a bag filter 7 via a pipeline. A second shut-off fan 8 is installed at the discharge outlet at the bottom of the bag filter 7. The second shut-off fan 8 is connected to the pipeline between the crusher 2 and the fan 4 via a connecting pipeline 9.
[0017] Optionally, the connecting pipe 9 includes a distribution pipe 901 connected to the second blower 8, the lower end of the distribution pipe 901 is connected to the guide pipe 902, and the outer end of the guide pipe 902 is connected to the pipe between the crusher 2 and the blower 4; a butterfly valve 10 is provided on the guide pipe 902 near the blower 4.
[0018] Optionally, an observation window 11 is provided on the distribution pipe 901 below the second fan 8. Through the observation window 11, the operator can observe the material falling in the distribution pipe 901 in a timely manner to ensure the normal operation of the device, and can also observe the fineness of the powder.
[0019] Optionally, the bag filter 7 has two sets of outlets, and the distribution pipes 901 on each of the second blowers 8 are respectively connected to the guide pipes 902.
[0020] Optionally, the bag filter 7 is a pulse dust collector bag filter.
[0021] In operation, the refined cotton is opened by the cotton opener 1 and then smoothly enters the pulverizer 2. After initial pulverization, the powder is drawn into the cyclone separator 3 by the blower 4. At this time, the first shut-off blower 5 is closed, and the second shut-off blower 8 is opened. The powder is continuously separated in the cyclone separator 3 and discharged into the bag filter 7 through the outlet of the cyclone separator 3. After dust removal by the bag filter 7, the exhaust gas is discharged outward through the exhaust pipe at the top, while the powder is discharged into the distribution pipe 901 through its various outlets and the second shut-off blower 8, and then converges into the guide pipe 902. At this time, the butterfly valve 10 is in the open state, and the blower 4 draws the powder in the guide pipe 902 back into the cyclone separator 3. After repeating the above steps several times, once the powder mesh size meets the standard, the first shut-off blower 5 is opened, allowing the powder to flow through the pipeline into the cotton hopper 6 for unified collection. The entire process liberates a significant amount of manual labor. Its reasonable structural design and convenient operation replace manual handling with pipeline transportation, eliminating the need for manual bagging. It can effectively recycle powder, saving time and effort, reducing the labor intensity of manual operation, and eliminating the need for frequent checks on whether dust levels meet standards, significantly improving work efficiency, more effectively preventing dust spillage, eliminating pollution to the workshop environment, ensuring the health of workers, and solving the problems existing in the current technology.
