[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Examples, such as Figs. 1-4As shown, a two-stage dust removal device suitable for a delinting workshop aims to increase the dust removal effect during the delinting process, thereby improving the work progress and ensuring the quality of material forming. Specifically, it includes a delinting machine 1 for delinting materials, a collection pipe 2 above multiple delinting machines 1, a conveying pipe 3 on one side of the collection pipe 2, a conveying fan inside the conveying pipe 3, a primary mesh bag dust collector 4 at the end of the conveying pipe 3, a recovery pipe 5 below the primary mesh bag dust collector 4, a cone-shaped dust collection hood 6 outside the primary mesh bag dust collector 4, a secondary mesh bag dust collector 7 above the dust collection hood 6, and an exhaust port 71 on the outer side of the upper part of the secondary mesh bag dust collector 7. Specifically, the material processed by the delinting machine 1 is conveyed by the conveying fan and passes through the collection pipe 2... The material is conveyed through the conveying pipe 3 to the primary mesh bag dust collector 4, which can remove dust from the material. At the same time, the material remaining in the primary mesh bag dust collector 4 will be further removed by the airflow from the conveying pipe 7. The material after dust removal is collected by the recovery pipe 5. The dust after secondary dust removal is collected in the dust collection and treatment device 8, waiting for subsequent centralized processing. The above-mentioned two-stage dust removal method has a significant dust removal effect and can fully guarantee the forming quality of the material. The dust collection and treatment device 8 is installed below the dust collection hood 6. Its function is to discharge the dust after dust removal to the outside. At the same time, it can also collect the short fibers contained in the material, reducing the possibility of resource waste.

[0020] In the above process: the primary mesh bag dust collector 4 and the secondary mesh bag dust collector 7 are used in combination. This two-stage dust collection method is simple and convenient, and the dust removal effect is significant, which can effectively improve the processing quality of materials. The dust collection and treatment device 8 is used to centrally discharge the dust after dust removal. At the same time, it can also collect the short fibers contained in the dust, reducing the possibility of resource waste. This device is reasonably designed, simple in structure, easy to process, and can further improve the dust removal treatment of materials, ensuring the work progress. At the same time, it can realize convenient collection of dust to a certain extent, and can separate some of the material resources contained in it, reducing the possibility of resource waste and effectively meeting the usage requirements.

[0021] To facilitate the removal of dust collected after dust removal, the dust collection and treatment device 8 includes a receiving hood 81 connected to the dust collection hood 6. The upper half of the receiving hood 81 is cylindrical, and the lower half is conical. An extension pipe 811 is installed below the receiving hood 81, and an auger conveyor 82 is installed inside the extension pipe 811. A conical filter plate 83 is installed above the receiving hood 81, and a hemispherical support shell 84 is installed on the filter plate 83. A separation device 9 is installed above the auger conveyor 82 to separate dust and short fibers. Specifically, the dust in the dust collection hood 6 falls downward into the receiving hood 81, and then, under the action of the separation device 9, the dust is output downward through the filter plate 83, and some short fibers in the dust are separated by the separation device 9 for easy collection and removal later. The filter plate 83 is mainly for dust discharge, and at the same time, the separation device 9 can also scrape the inner wall of the equipment to ensure thorough dust fall and improve the working process.

[0022] To separate materials from dust and ensure thorough dust removal, the separation device 9 includes a drive shaft 91 that passes through the filter plate 83 and the support shell 84. An arc-shaped plate 92, adapted to the outer surface of the support shell 84, is mounted on the drive shaft 91 above the support shell 84. Collection teeth 921 are located on the inner side of the arc-shaped plate 92. A support rod 93 is located on the outer side above the drive shaft 91. An axe-shaped material-pushing plate 94 is located on one side of the support rod 93, with its lower end connected to the lower end of the arc-shaped plate 92. Specifically, the output end of the auger conveyor 82 is located below it. The output power of the auger conveyor 82 drives the drive shaft 91 to rotate. The material-pushing plate 94 above the filter plate 83 can both scrape the dust downwards, allowing it to pass through the filter plate 83, and also remove the material on the filter plate 83. The dust collection device 83 is used to thoroughly scrape the material to ensure complete discharge and facilitate subsequent dust removal. For any short fibers that may be present in the dust within the containment hood 81, the filter plate 83 can separate them to a certain extent. The remaining material falls onto the support shell 84. During this process, the collecting teeth 921 rotate with the arc-shaped plate 92, which on one hand removes the short fibers, and on the other hand guides the dust from the support shell 84 to the filter plate 83, ensuring thorough dust removal and collection of short fibers. This improves the work process, reduces the possibility of material waste, and meets usage requirements. Of course, when it is necessary to collect and remove the short fibers, the dust collection and processing device 8 can be disassembled. While removing the short fibers, they can also be cleaned to ensure optimal performance.

[0023] To further improve the rationality of the device setup, a scraper 95 is installed on the drive shaft 91 located below the filter plate 83. The number of scraper 95 is the same as the number of feed plates 94, and the two are staggered in the vertical position. When dust falls from the filter plate 83, the scraper 95 can guide the dust into the extension pipe 811 below, and then discharge it under the action of the auger conveyor 82. Furthermore, an inclined discharge hood 10 is provided on one side of the extension pipe 811, which limits the direction of dust discharge. This not only ensures effective power input but also facilitates the discharge of dust, improving the functionality of the device.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
