Description

Technical Field

[0001] This utility model relates to the technical field of coal slime treatment devices, specifically a coal slime drying device. Background Technology

[0002] Coal slime is a semi-solid substance containing water from coal powder. When processing coal slime, it is often necessary to dry it. However, existing drying equipment has low drying efficiency and cannot achieve the drying effect quickly in a short time, so it needs to be improved.

[0003] To address the aforementioned technical issues, existing drying devices employ either extending the drying distance or using a flipping method. While both methods do improve drying efficiency, certain technical problems remain. Firstly, extending the drying distance results in excessively long equipment, occupies a large area, and increases manufacturing costs. Secondly, while the flipping method can improve drying efficiency, simply flipping does not significantly increase efficiency.

[0004] Therefore, in order to reduce manufacturing costs and improve drying efficiency, a coal slime drying device is proposed to overcome the technical problems in the prior art. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] Please see Figure 1-8 This utility model provides the following technical solution: a coal slime drying device, including a frame 1, a feeding structure, and a crushing structure. A drying structure for drying coal slime is installed on the frame 1. The drying device includes a drying box 2 installed at the upper end of the frame 1. A conveying structure for transporting coal slime is installed inside the drying box 2. A crushing and segmenting structure for crushing and segmenting the coal slime is also installed inside the frame 1. This structure includes a stepper motor 14, a pressure roller 15, a transverse plate 16, a cutting circular plate 17, a first shaft 25, a second shaft 26, and a third shaft 27. The stepper motor 14 is mounted on the rear end of the drying chamber 2 via a mounting base. Its output end is connected to a shaft 25 that passes through the drying chamber 2 and extends to the front end of the drying chamber 2. The pressure roller 15 is mounted on the outer surface of the shaft 25. The drying chamber 2 is also connected to a shaft 26 and a shaft 27. The shaft 25, shaft 26 and shaft 27 are all equipped with pulleys, and the pulleys are connected to each other by a transmission belt. The shaft 26 is equipped with a transverse plate 16 in a ring array, and the shaft 27 is equipped with cut circular plates 17 at equal intervals.

[0029] In this implementation plan, the specific working principle is as follows: Coal slurry is introduced into the feeding structure, and then enters the conveying structure. Through the transmission action of the conveying structure, the coal slurry sequentially contacts the pressure roller 15, the transverse plate 16, and the cutting disc 17. Driven by the stepper motor 14, the shaft 25 rotates. (See reference...) Figure 7 As can be seen, the pulleys and transmission belts on the surfaces of shaft 1 (25), shaft 2 (26), and shaft 3 (27) achieve a linkage effect, thereby pressing the coal slime into a thin state according to the pressure roller 15. Then, the transverse plate 16 and the cutting circular plate 17 make the coal slime into square pieces. The drying structure continuously dries the coal slime, which can quickly evaporate the moisture in the coal slime. Then, the coal slime enters the crushing structure and is crushed into fine coal slime particles. During crushing, the hot air of the drying structure will continuously enter, thereby further improving the drying effect and efficiency of the coal slime.

[0030] Based on the above, the specific details of the conveying structure can be found in [reference needed]. Figure 1 , Figure 3 , Figure 4As can be seen, the conveying structure includes a second geared motor 8, a drive shaft 24, and a conveyor belt 23. The second geared motor 8 is installed on the front end of the drying box 2, and the output end is equipped with a drive shaft 24 that passes through the drying box 2. The drive shaft 24 is symmetrically distributed on the vertical longitudinal section of the drying box 2. The conveyor belt 23 is installed on the surfaces of the two sets of drive shafts 24. The second geared motor 8 drives the drive shaft 24 to rotate, thereby causing the conveyor belt 23 to transport the coal slime from left to right.

[0031] For details regarding the drying structure, please refer to [link / reference needed]. Figure 4 as well as Figure 3 As can be seen, the drying structure also includes an outer shell 4, a heating tube 5, and a fan 6. The outer shell 4 is installed on the upper surface of the drying chamber 2, and the upper surface of the drying chamber 2 has a square opening, which is covered by the outer shell 4. The heating tube 5 is provided on the inner side of the outer shell 4, and the fan 6 is symmetrically installed on the upper surface of the outer shell 4. The heating tube 5 is electrically heated, and then the fan 6 introduces air into the vicinity of the heating tube 5 to form hot air, which is then blown onto the coal slime to dry the coal slime.

[0032] For details on the broken structure, please refer to [link / reference]. Figure 4 and Figure 6 As can be seen, the crushing structure includes a crushing box 10, a support 11, a second feeding hopper 12, a servo motor 13, a rotating shaft 20, and a crushing rod 21. The crushing structure is located below the drying box 2. The crushing box 10 is installed on the support 11. The servo motor 13 is installed on the upper end of the crushing box 10. The rotating shaft 20, which extends through to the inner side of the crushing box 10, is installed at the output end of the servo motor 13. The crushing rod 21 is installed on the surface of the rotating shaft 20. The second feeding hopper 12 is installed on the lower end of the crushing box 10. The rotating shaft 20 is rotated by the servo motor 13, thereby crushing the coal slime blocks through the crushing rod 21.

[0033] See Figure 1 As can be seen, the upper surface of the crushing box 10 is provided with a square opening, and the lower side of the drying box 2 is also provided with a square opening on the right side. The two sets of square openings correspond to each other and are connected by the feeding funnel 9.

[0034] For details on the feeding structure, please refer to [link / reference]. Figure 3 and Figure 4 As can be seen, the feeding structure includes a feeding hopper 3, a mounting plate 22, and a geared motor 7. The feeding hopper 3 is installed on the upper left side of the drying box 2. The mounting plate 22 is installed on the upper surface of the feeding hopper 3. The geared motor 7 is installed on the upper end of the mounting plate 22. The output end of the geared motor 7 is connected to a shaft. The surface of the shaft is provided with a spiral plate. The geared motor 7 drives the shaft to rotate, and the coal slime is fed through the spiral plate.

[0035] To prevent coal slurry lumps from sticking to the conveyor belt 23 due to the crushing action of the pressure roller 15, please refer to [the relevant documentation]. Figure 4As can be seen, a scraper 19 is horizontally connected to the inner side of the drying box 2. The upper end of the scraper 19 is in contact with the surface of the conveyor belt 23, and the scraper 19 has an inclined angle and faces the discharge hopper 9. In this way, the coal slime adhering to the conveyor belt 23 will be scraped off by the scraper 19. The scraped coal slime will slide into the discharge hopper 9 and enter the crushing structure.

[0036] In order to increase the contact area with air and thus facilitate heat generation, heat sinks 18 are evenly distributed on the surface of the heating tube 5.

[0037] To improve the crushing effect of the crushing rod 21 on coal slime blocks, please refer to the following: Figure 6 As can be seen, the two adjacent sets of breaking rods 21 are arranged alternately.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
