Description

Technical Field

[0001] The present invention relates to the technical field of recarburizer processing, and particularly to a preparation device and a preparation method for a coal-based recarburizer. Background Art

[0002] In the preparation process of traditional coal-based recarburizers, the pretreatment of raw materials is a crucial link, which directly affects the quality and performance of the final product. The influence of the particle size of the recarburizer on the absorption rate of the recarburizer depends on the combined effect of the dissolution and diffusion rate and the oxidation loss rate of the recarburizer. Generally, when the recarburizer particles are small, the dissolution rate is fast and the loss rate is large; the production of recarburizers requires crushing of raw materials.

[0003] In the traditional coal-based recarburizer preparation process, after the raw materials are carbonized and crushed, the particle sizes are uneven. Traditional screening equipment often has difficulty effectively distinguishing qualified particles from unqualified particles, resulting in low screening efficiency and prone to blockage during the screening process, affecting the continuity and stability of the production line. In addition, incomplete screening will also cause too many unqualified particles to be mixed into the final product, affecting the overall quality of the coal-based recarburizer. Therefore, the present invention proposes a preparation device and a preparation method for a coal-based recarburizer. Summary of the Invention

[0019] A preparation method of a coal-based carburizer includes:

[0020] S1: First, place the coal-based raw materials to be processed in the placement bin of the placement mechanism. Send the raw materials into the carbonization furnace through the transfer mechanism. Close the transparent cover of the carbonization furnace. Start the fuel pile to heat the carbonization furnace and perform carbonization treatment on the raw materials. The waste gas generated during the carbonization process is discharged through the exhaust pipe. After the carbonization is completed, open the transparent cover, and use a cable to connect an external winch to pull the placement bin to transport the carbonized raw materials out of the carbonization furnace;

[0021] S2: Open the pull cover, send the carbonized raw materials into the crushing box of the crushing mechanism, then start the first motor to drive the first rotating shaft and the square rotating body to rotate, so that the crushing rod crushes the carbonized raw materials. The crushed raw materials are discharged from the bottom outlet of the crushing box and enter the screw conveying cylinder through the discharge hopper. Start the second motor of the conveying mechanism, and convey the crushed raw materials to the discharge hopper through the rotation of the screw in the screw conveying cylinder. The crushed raw materials fall from the discharge hopper onto the screening plate of the screening mechanism, ready for screening;

[0022] S3: Start the vibration motor of the screening mechanism to make the screening plate vibrate and screen the raw materials. When the screening process lasts for a long time, to prevent the blockage of the screening plate, start the third motor. The third motor drives the rotating body to rotate, and through the rotation of the rotating body, the spiral groove and the sliding piece on it move relatively, thereby driving the U-shaped frame to perform a linear reciprocating motion. The movable rod fixedly connected to the U-shaped frame drives the slider to slide in the chute, so as to drive the connecting frame to perform a reciprocating motion through the extension block, squeeze the second spring, enhance the screening effect, avoid the blockage of the screening plate during the long-term screening process. The qualified particles after screening fall into the diversion groove through the screening plate, while the unqualified particles fall onto the circulating belt through the inclined screening plate, and the unqualified particles are re-transported to the crushing mechanism through the circulating belt for re-crushing;

[0023] S4: The qualified particles after screening flow from the diversion groove into the mixing cylinder of the mixing mechanism. Start the fourth motor to drive the second rotating shaft and the mixing rod to rotate, and mix the raw materials. The mixed raw materials are the finished coal quality carbonizer, and then subsequent packaging and storage are carried out.

[0024] The beneficial effects of the present invention are:

[0025] 1. Through the close cooperation of the carbonization mechanism, transfer mechanism, crushing mechanism, transportation mechanism, screening mechanism and mixing mechanism in the present invention, the continuous production of coal quality carbonizer is realized. From the carbonization treatment of raw materials to the final mixing and packaging, the connection between each step is tight, reducing the waiting time and manual intervention in the production process, and significantly improving the production efficiency.

[0026] 2. By adopting the design of vibration motor and reciprocating motion in the present invention, the screening plate generates strong vibration, effectively improving the screening efficiency. At the same time, through the relative movement of the spiral groove and the sliding piece, the U-shaped frame is driven to perform a linear reciprocating motion, further enhancing the screening effect and avoiding the blockage phenomenon during the screening process. This design not only improves the screening efficiency but also ensures the accuracy of screening, greatly reducing the content of unqualified particles in the final product. And through the set circulating belt, the closed-loop treatment of unqualified particles is realized, improving the resource utilization rate and the overall treatment efficiency.

[0060] In another embodiment provided by the present invention, as Figures 7-10 shown, the screening mechanism 6 includes a second support frame 601 and a chute 619.

The qualified particles after screening fall into the diversion trough 605 through the screening plate 604, and the unqualified particles are re-transported to the crushing mechanism 4 through the circulating belt 8 for re-crushing.

A plurality of mixing rods 705 are arranged on the outer surface of the second rotating shaft 704 along the axial direction. By starting the fourth motor 703, the second rotating shaft 704 and the mixing rods 705 are driven to rotate, and the raw materials are uniformly mixed. The uniformly mixed raw materials are the finished coal-based carbon increasing agent.

[0063] A preparation method of a coal-based carbon increasing agent:

[0064] S1: First, place the coal-based raw materials to be processed in the placement bin 301 of the placement mechanism 3. The raw materials are sent into the carbonization furnace 102 through the transfer mechanism 2. Close the transparent cover 106 of the carbonization furnace 102, start the fuel pile 104 to heat the carbonization furnace 102, and perform carbonization treatment on the raw materials. The waste gas generated during the carbonization process is discharged through the exhaust pipe 103. After the carbonization is completed, open the transparent cover 106, and pull the placement bin 301 by connecting the external winch through the cable 303 to transport the carbonized raw materials out of the carbonization furnace 102;

[0065] S2: Open the pull cover 403, send the carbonized raw materials into the crushing box 402 of the crushing mechanism 4, and then start the first motor 4067 to drive the first rotating shaft 4061 and the square rotating body 4062 to rotate, so that the crushing rods 4063 crush the carbonized raw materials. The crushed raw materials are discharged from the bottom outlet of the crushing box 402 and enter the screw conveying cylinder 501 through the discharge hopper 503. Start the second motor 505 of the transportation mechanism 5, and the screw in the screw conveying cylinder 501 rotates to transport the crushed raw materials to the discharge hopper 503. The crushed raw materials fall from the discharge hopper 503 onto the screening plate 604 of the screening mechanism 6 to prepare for screening;

[0066] S3: Start the vibration motor 606 of the screening mechanism 6 to vibrate the screening plate 604 and screen the raw materials. When the screening process lasts for a long time, to prevent the blockage of the screening plate 604, start the third motor 613. The third motor 613 drives the rotating body 614 to rotate. The rotation of the rotating body 614 drives the spiral groove 615 and the sliding piece 616 thereon to move relatively, thereby driving the U-shaped frame 617 to perform a linear reciprocating motion. The movable rod 618 fixedly connected to the U-shaped frame 617 drives the slider 621 to slide in the chute 619, and then drives the connecting frame 603 to perform a reciprocating motion through the extension block 620, squeezing the second spring 608 to enhance the screening effect and avoid the blockage of the screening plate 604 during the long-time screening process. The qualified particles after screening fall into the diversion groove 605 through the screening plate 604, while the unqualified particles fall onto the circulating belt 8 through the inclined screening plate 604, and the unqualified particles are re-transported into the crushing mechanism 4 through the circulating belt 8 for re-crushing;

[0067] S4: The qualified particles after screening flow into the mixing cylinder 701 of the mixing mechanism 7 from the diversion groove 605. Start the fourth motor 703 to drive the second rotating shaft 704 and the mixing rod 705 to rotate, and mix the raw materials. The mixed raw materials are the finished coal quality carbon additive, and then subsequent packaging and storage are carried out.
