Description

Technical Field

[0001] This utility model relates to the field of cleaning and impurity removal technology, specifically, to a wind-screen cleaning device suitable for the preparation of cotton stalk particleboard raw materials. Background Technology

[0002] Cotton stalks, a byproduct of cotton production, are rich in lignin, cellulose, and hemicellulose, possessing good strength and rigidity. They can replace traditional wood as a primary raw material for particleboard production, resulting in lightweight and high-strength particleboard. However, after crushing and separating the cotton stalks, the strong adhesion of the cotton fibers makes them prone to clumping, hindering the screening of the crushed stalk-peel-pith mixture. This introduces impurities during particleboard production, damaging the quality of the particleboard. To avoid this and ensure the quality and cleanliness of the production process, cleaning and impurity removal from the cotton stalk raw materials is essential.

[0003] Currently, cleaning devices suitable for preparing cotton stalk biomass raw materials are not very mature. Existing cotton stalk particleboard raw material cleaning devices have complex structures, and their structural and operating parameters cannot be well adapted to actual screening needs. They have many problems and cannot meet the current market requirements. Using manual screening is still very costly, and the efficiency has not been significantly improved.

[0004] In view of this, a wind-screen cleaning device suitable for the preparation of cotton stalk particleboard raw materials is proposed. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a cleaning device for cotton stalk particleboard preparation by filtering and screening cotton stalk raw materials through a wind-screen cleaning method, which can help discharge impurities from the drum mechanism and the wind-screening mechanism.

[0006] The filtration of the air-screen cleaning device helps to remove impurities from the drum mechanism and the air separation mechanism, improving the cleanliness of cotton stalk raw material utilization. At the same time, the spiral conveyor mechanism set between the drum mechanism and the air separation mechanism can promptly transport the cotton stalk raw material after preliminary impurity removal, reducing the impact of poor raw material transportation on the overall normal operation of the device.

[0007] Therefore, this utility model provides an air-screen cleaning device suitable for the preparation of cotton stalk particleboard raw materials. The air-screen cleaning device includes a roller mechanism 1, a screw conveyor mechanism 2, and an air-separating mechanism 3. The roller screen 4 of the roller mechanism 1 is inclined.

The input end of the screw conveyor mechanism 2 is connected to the discharge port 6 of the roller mechanism 1. The discharge pipe 7 at the output end is provided with the inlet 8 of the air-separating mechanism 3 below it. The air-separating mechanism 3 is connected to the blower 10 and the air-separating box 11 through the air inlet pipe 9. The collection box 12 is placed on the lower side of the air-separating box 11 to receive useful materials.

[0008] As a further improvement to this technical solution, the roller mechanism 1 includes a roller frame 13, a roller screen 4, a roller baffle 14, a drive motor 15, and driven rollers 5. The roller screen 4 is arranged above the roller frame 13 and is inclined. The driven rollers 5 are respectively arranged at both ends of the roller screen 4. The roller baffles 14 are all fixedly connected to the roller frame 13.

[0009] As a further improvement to this technical solution, a drive motor 15 is installed on the outside of the roller frame 13. The drive motor 15 drives the drive sprocket 16 to rotate. The drive sprocket 16 meshes with the chain 17. The drive sprocket 16 drives the driven sprocket 18 to rotate through the chain 17.

[0010] As a further improvement to this technical solution, the driven sprocket 18 meshes with the chain 17, and the driven sprocket 18 cooperates with the rotating shaft 19 to drive the driven support roller 5 to rotate. The drum screen 4 is driven to work by the rotation of the driven support roller 5. The cotton straw raw material is screened by the drum screen 4 and then output from the discharge port 6.

[0011] As a further improvement to this technical solution, the screw conveying mechanism 2 includes a base plate 20, a conveying cylinder 21, a discharge pipe 7, and a support arm 22. The base plate 20 is provided with a support arm 22, which is fixedly connected to the conveying cylinder 21. The conveying cylinder 21 is provided with a screw conveyor 23, which transmits cotton straw raw materials through the screw conveyor 23 and then outputs them to the next stage through the discharge pipe 7.

[0012] As a further improvement to this technical solution, the air separation mechanism 3 includes an air inlet pipe 9, a blower 10, a feed inlet 8, an air separation box 11, a collection box 12, and a dust removal port 24. The air inlet end of the air inlet pipe 9 is connected to the blower 10, and the air outlet end of the air inlet pipe 9 is connected to the air separation box 11. The top of the air separation box 11 is provided with a feed inlet 8, and the tail of the air separation box 11 is provided with a dust removal port 24.

[0013] As a further improvement to this technical solution, the bottom of the air classifier 11 is sequentially provided with a first discharge port 25, a second discharge port 26 and a third discharge port 27, and a collection box 12 is provided below the air classifier 11. The collection boxes 12 are all fixedly connected to the air classifier frame 28.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0026] Please see Figures 1-7 This invention relates to an air-screen cleaning device suitable for preparing cotton stalk particleboard raw materials. The device includes a roller mechanism 1, a screw conveyor mechanism 2, and an air-screening mechanism 3. The roller screen 4 of the roller mechanism 1 is inclined, and the driven rollers 5 support both ends of the roller screen 4 and cooperate with its rotation. The input end of the screw conveyor mechanism 2 is connected to the discharge port 6 of the roller mechanism 1, and the inlet 8 of the air-screening mechanism 3 is located below the discharge pipe 7 at the output end. The air-screening mechanism 3 is connected to a blower 10 via an air inlet pipe 9 and a ventilation box 11. A collection box 12 is placed below the ventilation box 11 to receive useful materials.

[0027] Considering the installation and fixing of the roller mechanism 1, in order to further improve the fixing effect of the roller screen 4, the outside of the roller screen 4 is provided with a roller frame 13 and a driven support roller 5 for auxiliary fixing of the roller screen 4, so that the supporting force of the roller screen 4 is distributed to both ends of the roller screen 4. This can avoid the supporting force being concentrated at one end, and make the roller screen 4 of the roller mechanism 1 work more stably.

[0028] The improvement lies in the following: driven rollers 5 are respectively set at both ends of the outer side of the drum screen 4. The driven rollers 5 are used to support both ends of the drum screen 4 and cooperate with the rotation of the drum screen 4. They have the same speed and good stability, ensuring that there is no relative torque between the front and rear ends of the drum screen 4. This can effectively limit the movement of the drum screen 4 and reduce the displacement of the drum screen 4 during use, thereby improving the stability of the drum mechanism 1 during operation.

[0029] Since the raw materials screened in the air separation mechanism 3 are all transported by the screw conveyor mechanism 2, and the air separation mechanism 3 is easily affected by uneven feeding, resulting in excessively high impurity content of the air-separated materials, in order to reduce the impact of uneven feeding on the air separation screening effect, and at the same time further improve the installation stability of the screw conveyor mechanism 2 and improve the uniform and efficient material transportation effect of the cleaning device, a support arm 22 is provided on the base plate 20, so that the support arm 22 is fixedly connected to the bottom of the conveying cylinder 21. The input end of the screw conveyor mechanism 2 is connected to the discharge port 6 of the roller mechanism 1, and the discharge pipe 7 at the output end is provided with the inlet 8 of the air separation mechanism 3, which significantly improves the cleaning processing efficiency.

[0030] The improvements are as follows: after initial screening, the material is transported step by step by the screw conveyor mechanism 2. The input end of the screw conveyor mechanism 2 is connected to the discharge port 6 of the roller mechanism 1, which reduces the collision and buffering of cotton stalks and avoids material splashing, thus effectively improving the uniform and stable supply of raw materials. The support arm 22 on the base plate 20 can effectively limit the screw conveyor mechanism 2, improving the stability of the screw conveyor mechanism 2 during operation. The overall structure is simple and easy to implement, with high coordination and integration of automated production line conveying, and simple and convenient operation.

[0031] Considering the installation stability of the air classifier 3, in order to further improve the installation stability of the air classifier box 11 and improve the quality and efficiency of the air-classified materials, the air classifier box 11 is fixed between the air classifier frames 28 to reduce the displacement of the air classifier box 11 during air classification, thereby improving the stability of the air classifier 3 during operation.

[0032] The improvement lies in the fact that by fixing the air separator box 11 between the air separator frame 28, and with the combined blowing of the blower 10 and the air inlet pipe 9, the cotton stalk raw material can be air-separated and screened in the air separator box 11, and the cotton stalk raw material can be fully separated. The separated cotton stalk raw material is then carried away by the collection box 12 of the air separator mechanism 3 for centralized collection and processing, which effectively improves the installation stability of the air separator mechanism 3 and makes it easier to clean the impurities collected in the collection box 12.

[0033] In summary, the working principle of this scheme is as follows: First, the cotton stalk raw material to be processed is rotated and screened through the drum screen 4 inside the drum mechanism 1. The drive motor 15 drives the driven roller 5 to rotate via chain transmission, causing the drum screen 4 to rotate accordingly. After being screened by the drum screen 4, the cotton stalk raw material is output from the discharge port 6. Then, the input end of the screw conveyor 2 is connected to the discharge port 6 of the drum mechanism 1, thereby accelerating the forward speed of the cotton stalk raw material in the screw conveyor 2, reducing the accumulation of cotton stalk raw material at the input end of the screw conveyor 2, and achieving material processing efficiency. The conveying connection is highly coordinated. As the cotton stalk raw material enters the air separator 11 through the feed inlet 8, the blower 10 and the air inlet pipe 9 work together to blow air, causing the cotton stalk raw material and impurities to be blown into the collection box 12 respectively. After passing through the roller mechanism 1 and the air separator 3, the cotton stalk raw material can filter out impurities such as cotton bark, cotton pith and residual cotton, which can fully remove impurities from the raw material, while ensuring the smoothness of feeding and improving the cleanliness of the raw material. This ensures the subsequent production and processing of cotton stalk particleboard and also improves the quality of cotton stalk particleboard.
