Description

Technical Field

[0001] This utility model relates to the technical field of bamboo fiber production equipment, and in particular to a bamboo fiber dust purification device. Background Technology

[0002] Bamboo fiber is a cellulose fiber extracted from naturally grown bamboo. It is hailed as the fifth major natural fiber after cotton, linen, wool, and silk. It has good breathability, instant water absorption, strong abrasion resistance, and good dyeability. It also has natural antibacterial, bacteriostatic, mite-repellent, deodorizing, and UV-resistant functions. Bamboo fiber includes natural bamboo raw fiber and chemical bamboo fiber. Natural bamboo raw fiber is produced by a combination of physical and chemical methods. Its main components are cellulose, hemicellulose, and lignin. It has antibacterial, deodorizing, and UV-resistant functions. Chemical bamboo fiber includes bamboo pulp fiber and bamboo charcoal fiber. Bamboo pulp fiber is made by making bamboo strips into pulp and then wet spinning. Bamboo charcoal fiber is made by adding nano-sized bamboo charcoal powder to viscose spinning solution.

[0003] The following problems exist: During the production of bamboo fiber, a large amount of fine dust is inevitably generated. This dust permeates the air, causing great distress to workers. In order to protect their health, workers have to wear masks and protective goggles to reduce the direct harm of dust to the respiratory system and eyes. However, despite these protective measures, the dust generated cannot be completely controlled. It still floats in the air and spreads everywhere. This not only threatens the health of people passing by the production site, exposing them to dust pollution and making them prone to respiratory diseases or other health problems, but also damages the surrounding environment. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0018] Reference Figure 1-3 This utility model provides an embodiment of a bamboo fiber dust purification device, including a separation cylinder 1, a recovery cylinder 2 threadedly connected to the bottom of the inner wall of the separation cylinder 1, a guide wall 3 fixedly connected to the top of the inner wall of the separation cylinder 1, a sealed air duct 4 penetrating the top of the outer wall of the separation cylinder 1, and a dust suction hood 5 fixedly connected to the top of the sealed air duct 4. By setting the dust suction hood 5, the generated bamboo fiber dust can be concentrated and guided into the sealed air duct 4, thereby reducing the dust diffusion in the working area. A cyclone separator 6 is fixedly connected to the bottom of the sealed air duct 4, and a guide pipe 7 is fixedly connected to the top of the separation cylinder 1. By setting the cyclone separator 6, the first-stage processing unit of the device, the dust-laden airflow enters the cylindrical separation chamber at high speed along the tangential direction. The strong centrifugal force throws most of the coarser and heavier bamboo fiber dust particles toward the guide wall 3. The dust particles rotate and fall along the guide wall 3 and converge into the recovery cylinder 2 at the bottom. The relatively purified airflow is discharged from the top guide pipe 7. A conveying pipe 8 is fixedly connected to the top of the guide pipe 7, and a plug ring 9 is sleeved on one end of the outer wall of the conveying pipe 8.

[0019] A water-soluble settling tank 10 is fixedly connected to the outer wall of the insertion ring 9. A tempered glass plate 11 passes through the front end of the water-soluble settling tank 10. U-shaped bases 12 are fixedly connected to both ends of the bottom of the water-soluble settling tank 10. A water tank 13 is fitted into the inner wall of the U-shaped base 12. By setting up the water tank 13, the water for settling spraying can be stored and a certain water level can be maintained. A water pump 14 passes through the rear end of the water tank 13. A water inlet pipe 15 is fixedly connected to the front end of the water pump 14. A placement frame 1 is fixedly connected to the top of the inner wall of the water tank 13. 6. It is worth noting that a liquid level sensor is installed at the bottom of the placement frame 16 to prevent the water level from overflowing due to excessively high levels or affecting the effect due to excessively low levels. A screen frame 17 is fitted into the inner wall of the placement frame 16. A screen body 18 is fixedly connected to the bottom of the inner wall of the screen frame 17. A top cover 19 is fitted into the top of the inner wall of the water-soluble sedimentation tank 10. A spray head 20 is inserted through the center of the top of the top cover 19. A water supply pipe 21 is inserted into the top inlet of the spray head 20. The end of the water supply pipe 21 is inserted into the outlet of the rear end of the water pump 14.

[0020] An induced draft fan 22 is installed at the top of one side of the outer wall of the water-soluble settling tank 10. The induced draft fan 22 serves as the power source for the entire system. A moisture-resistant and corrosion-resistant fan can be selected. By installing multiple rows of fine atomizing spray heads 20 above the water-soluble settling tank 10, a high-density water mist curtain or spray zone can be formed. The airflow carrying the remaining fine dust passes through the water mist zone at high speed. The dust particles collide with, are wetted, and agglomerate with the fine water droplets. The mass of the wetted and wrapped dust particles increases, or they collide with the water surface in the turbulent mixing zone and settle rapidly. The bamboo fiber dust, mainly composed of organic matter, is readily hydrophilic and can effectively dissolve or form a suspension slurry upon contact with water in the water tank 13. This effectively suppresses the dust's airborneness and flammability. A small amount of antifoaming agent or flocculant can also be added to the spray water in the water tank 13, primarily to prevent foaming and promote sedimentation. By setting up the screen body 18, the concentrated slurry of settled bamboo fiber dust can be filtered. The cleaned spray water will fall to the bottom of the water tank 13. The installation of the water pump 14 and water delivery pipe 21 facilitates the recycling of the water source.

[0021] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
