[0002] In the coal processing industry, coal separators are crucial equipment for achieving efficient coal separation. They improve coal quality and meet the needs of various industrial applications by separating coal from impurities such as gangue. However, existing coal separators still face numerous problems in practical applications, particularly in terms of energy consumption. Traditional coal separators typically rely on high-power drive equipment and complex mechanical structures to complete the separation operation. This design not only leads to high energy consumption but also increases operating costs and maintenance complexity. Furthermore, existing equipment has limited material processing efficiency during the separation process, often requiring multiple separations to achieve the desired effect, further exacerbating energy waste and extending production cycles.

[0023] This utility model provides an energy-saving coal preparation and separation machine, the structure of which is as follows: Figures 1 to 3 As shown in the figure. This device achieves efficient material sorting through a combination of mechanical and pneumatic methods, and significantly reduces energy consumption and manual maintenance costs during operation. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and markings.

[0024] First, refer to Figure 1The schematic diagram of the overall structure shown illustrates that the sorting box 1 is the core component of this invention, used to contain and complete the material sorting process. The top of the sorting box 1 has a feed inlet 2 for guiding the coal to be sorted into the sorting box. Below the feed inlet 2 is a distribution plate 3, which is fixedly connected to the inner wall of the sorting box via a vibration mechanism 4. The vibration mechanism 4 enables the distribution plate to generate high-frequency vibration, thereby ensuring that the coal entering the sorting box is evenly distributed and avoiding accumulation that would affect subsequent sorting efficiency. Below the distribution plate 3 are two sets of guide plates 5, located symmetrically on both sides of the inner wall of the sorting box. The function of the guide plates is to guide the coal to flow along a predetermined path, reducing random scattering of materials within the sorting box.

[0025] The rotating shaft 6 is one of the key transmission components of this invention. Its two ends are rotatably connected to the side wall of the sorting box 1 via bearings, allowing the shaft to rotate freely within the sorting box. Several material-pushing plates 7 are evenly arranged on the outer wall of the rotating shaft 6. One end of each material-pushing plate 7 has an arc-shaped protrusion 8, the surface of which is coated with a wear-resistant coating 32 to enhance its wear resistance and extend its service life. The surface of the material-pushing plate 7 also has anti-slip textures 31, which increase the friction with the coal and improve the stability when moving the material. When the rotating shaft 6 rotates, the material-pushing plates 7 rotate accordingly, using the arc-shaped protrusion 8 to move the material for preliminary sorting. This process effectively separates coal of different particle sizes and prevents material from adhering to the surface of the material-pushing plates.

[0026] To further improve sorting efficiency, this invention features two sets of adjusting rods 9 symmetrically arranged at the center of the outer wall of the rotating shaft 6. One end of each adjusting rod is hinged to a first connecting rod 10, and the other end of the first connecting rod 10 is hinged to a scraper 11. Two sets of sliders 12 are symmetrically arranged on the outer wall of the scraper 11. The sliders 12 are fitted onto an elastic element 13, with one end of the elastic element 13 contacting the scraper 11 and the other end abutting against the inner wall of the sorting box 1. The inner wall of the sorting box 1 has a groove 14 that allows the sliders 12 to slide. The groove 14 has a T-shaped cross-section, which prevents the sliders from disengaging from the groove while ensuring the scraper moves smoothly along it. When the rotating shaft 6 rotates, the adjusting rods 9 drive the first connecting rod 10, which in turn pushes the scraper 11 to slide along the groove 14. During this sliding process, the scraper 11 scrapes away the coal material adhering to the inner wall of the sorting box, preventing material residue from affecting the sorting efficiency. After sorting is completed, releasing the applied force will allow the scraper 11 to automatically reset under the action of the elastic element 13, thereby simplifying the operation process and reducing the frequency of manual cleaning.

[0027] The bottom of the sorting box 1 is equipped with a discharge port 15 for discharging the sorted coal. A screen 16 is installed above the discharge port 15. Two sets of support rods 17 are symmetrically arranged on both sides of the screen 16. One end of each support rod is fixedly connected to the screen, and the other end is connected to the inner wall of the sorting box 1 via a spring 18. The screen 16 is designed to perform secondary screening of the coal, ensuring that the final output coal meets the particle size requirements. The combination of the support rods 17 and springs 18 not only provides stable support for the screen but also acts as a buffer when the screen is subjected to impact or vibration, protecting it from damage.

[0028] The power mechanism is an important component of this utility model, and its structure is as follows: Figure 3 As shown. The power mechanism includes two sets of cylinders 19 symmetrically arranged on the outer wall of the sorting box 1. Each set of cylinders has a piston rod 20 at one end, one end of which is fixedly connected to the outer wall of the sorting box 1, and the other end extends into the cylinder and is connected to the piston. One end of the cylinder 19 is connected to the air storage tank 22 through a first air pipe 21. The top of the air storage tank 22 is provided with a second air pipe 23. One end of the second air pipe 23 is connected to a pressure regulating valve 24, and the other end of the pressure regulating valve 24 is provided with an exhaust port 25. The air storage tank 22 is used to store compressed air, and the gas pressure is adjusted by the pressure regulating valve 24 to control the working state of the cylinder 19. The lower end of the first air pipe 21 passes through the sorting box 1 and the rotating shaft 6 in sequence and connects to a third air pipe 26. One end of the third air pipe 26 is connected to an air chamber 27, which is located inside the sorting box 1. A return spring 28 is provided in the air chamber 27. One end of the return spring 28 is connected to the inner wall of the air chamber, and the other end is connected to the piston. When cylinder 19 operates, compressed air enters air chamber 27 through first air pipe 21 and third air pipe 26, pushing the piston to move and thus driving shaft 6 to rotate. The upper end face of third air pipe 26 is in contact with the lower end face of first air pipe 21, and two sets of sealing rings 29 are provided inside the contact area. The interior of the two sets of sealing rings is filled with grease 34 to ensure the sealing and lubrication of gas transmission. The cross-section of sealing ring 29 is U-shaped, and the two sets of sealing rings are fixedly connected to the inner walls of first air pipe 21 and third air pipe 26 respectively, further improving the sealing effect.

[0029] In addition, a drive handle 30 is provided at one end of the rotating shaft 6. When manual operation is required, the rotating shaft 6 can be directly driven to rotate by rotating the drive handle 30. The rotating shaft 6 and the material feeding plate 7 are rotatably connected to the sorting box 1 and the rotating shaft respectively through bearings. This design can reduce friction loss and improve transmission efficiency. Sealing gaskets 33 are provided between the piston and the cylinder and between the piston and the air chamber to prevent gas leakage and ensure the normal operation of the system.

[0030] In practical applications, the working principle of this invention is as follows: First, the coal to be sorted enters the sorting box 1 through the feed inlet 2. After being subjected to the action of the vibration mechanism 4, the coal is evenly distributed on the distribution plate 3 and flows into the sorting area along the guide plate 5. At this time, the power mechanism is activated, and compressed air in the air storage tank 22 enters the air chamber 27 through the first air pipe 21 and the third air pipe 26, pushing the piston to move, thereby driving the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, the material-pushing plate 7 rotates accordingly, using the arc-shaped protrusion 8 to push the material for preliminary sorting. At the same time, the adjusting rod 9 drives the first connecting rod 10 to move, pushing the scraper 11 to slide along the slide groove 14 to scrape off the coal adhering to the inner wall of the sorting box. After secondary screening by the screen 16, the sorted coal is discharged from the discharge port 15. Throughout the process, all components work together, significantly improving the sorting efficiency and reducing the frequency of manual cleaning, thereby reducing energy consumption and maintenance costs.

[0031] In summary, this utility model achieves efficient coal sorting through optimized structural design and the introduction of a pneumatic transmission system, while also being energy-saving, environmentally friendly, and easy to maintain, making it suitable for various coal preparation scenarios.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
