Description
Technical Field
[0001] This utility model relates to the technical field of raw coke processing equipment, and in particular to a raw coke crushing and screening device. Background Technology
[0002] Raw coke plays a vital role in industries such as steel and chemicals. Its production process requires effective crushing and screening of raw materials to achieve suitable particle size and quality requirements. In raw coke production, it is crucial to thoroughly crush and accurately screen various raw coke materials such as coal and petroleum coke. In practical applications, raw coke raw material crushing and screening devices typically require the following technologies: 1. Highly efficient crushing mechanisms, such as jaw crushers and impact crushers, can break large pieces of raw materials into smaller particles.
[0003] 2. Precise screening systems, such as multi-layer vibrating screens, equipped with screens of different aperture sizes, to screen the crushed raw materials.
[0004] 3. Stable conveying equipment, such as belt conveyors, ensures smooth transportation of raw materials during crushing and screening.
[0005] Existing crushing and screening devices typically screen out larger particles that are not completely crushed after crushing, and then send the screened-out large particles back into the crushing mechanism for secondary crushing until the processing requirements are met.
[0006] However, during the implementation of the above technical solution, at least the following technical problems were found: feeding larger particles that do not meet the requirements back into the crushing mechanism for secondary crushing is cumbersome, and the use of a screen for screening is prone to screen blockage during use, which leads to ineffective screening and greatly reduces production efficiency. Utility Model Content
[0007] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a raw coke raw material crushing and screening device, which solves the technical problems of cumbersome operation of re-feeding larger particles that do not meet the requirements into the crushing mechanism for secondary crushing, and the use of screens for screening, which is prone to screen blockage during use, thus preventing effective screening and greatly reducing production efficiency.
[0008] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A raw coke crushing and screening device includes a crushing tank, a crushing cone rotatably mounted inside the crushing tank, a groove formed on the crushing cone, a second bearing fixedly mounted inside the crushing tank, a first bevel gear fixedly mounted on the outer wall of the second bearing, a transmission rod rotatably mounted inside the crushing tank, a second bevel gear fixedly mounted on the side end of the transmission rod, a reduction gearbox fixedly mounted on the side end of the crushing tank, and a motor fixedly mounted on the reduction gearbox; the gap between the crushing tank and the crushing cone gradually decreases from the outside to the inside, the inner wall of the first bevel gear is engaged in the groove, the first bevel gear can slide up and down along the groove, the first bevel gear meshes with the second bevel gear, the motor drives the transmission rod to rotate through the reduction gearbox, a hydraulic cylinder fixedly mounted inside the crushing tank, a connecting sleeve fixedly mounted at the end of the telescopic rod of the hydraulic cylinder, and the inner wall of the connecting sleeve fixedly connected to the top of the crushing cone.
[0009] Preferably, the inner wall of the first bearing is fixedly connected to the top of the rolling cone.
[0010] Preferably, a support frame is fixedly installed at the bottom of the crushing tank.
[0011] (III) Beneficial Effects 1. The rotating crushing cone crushes materials falling into the gap between the crushing tank and the crushing cone. During this process, as the gap between the crushing tank and the crushing cone gradually decreases from the outside to the inside, larger materials are trapped near the outer edge, while only smaller materials can move inward. The gradually narrowing gap between the crushing tank and the crushing cone separates materials of different sizes. Larger materials remain on the outside and are continuously crushed into smaller pieces by the rotating crushing cone, gradually approaching the opening at the bottom of the crushing tank until they become small particles that meet processing requirements. Finally, they are discharged from the opening at the bottom of the crushing tank and enter the conveying mechanism. By screening materials of different sizes through the gradually narrowing gap between the crushing tank and the crushing cone, and then gradually crushing them into the required particles by the rotating crushing cone, not only is clogging avoided, but the raw materials can also be crushed into the required size in one go, thus improving production efficiency.
[0012] 2. When it is necessary to adjust the size of the crushed particles, the hydraulic cylinder can be extended or retracted by controlling the hydraulic system. When the extension rod of the hydraulic cylinder retracts, it will drive the crushing cone to move upward through the connecting sleeve. At this time, the distance between the crushing cone and the crushing tank will increase, and the crushed particles will also become larger accordingly. When the extension rod of the hydraulic cylinder extends, it will drive the crushing cone to move downward through the connecting sleeve. At this time, the distance between the crushing cone and the crushing tank will decrease, and the crushed particles will also become smaller accordingly. This achieves the effect of adjusting the size of the crushed particles according to processing requirements. Attached Figure Description

[0016] This application provides a raw coke raw material crushing and screening device, which effectively solves the technical problem of cumbersome operation of re-feeding larger particles that do not meet the requirements into the crushing mechanism for secondary crushing, and the tendency of the screen to clog during use, resulting in ineffective screening and significantly reduced production efficiency. The rotating crushing cone crushes the raw material falling into the gap between the crushing tank and the crushing cone. During this process, as the gap between the crushing tank and the crushing cone gradually decreases from the outside to the inside, larger materials are stuck near the outer edge, while only smaller materials can continue to move inward. By screening materials of different sizes through the gradually narrowing gap between the crushing tank and the crushing cone, larger materials remain on the outside and are continuously crushed into smaller pieces by the rotating crushing cone, gradually approaching the opening at the bottom of the crushing tank until they become small particles that meet processing requirements. Finally, the larger materials are discharged from the crushing tank. The material discharged from the bottom opening of the crushing tank enters the conveying mechanism. Through the gradually narrowing gap between the crushing tank and the crushing cone, raw materials of varying sizes are screened. The rotating crushing cone then gradually crushes the raw materials into the required particles for production. This process not only avoids clogging but also crushes the raw materials to the required size in one pass, improving production efficiency. When the size of the crushed particles needs to be adjusted, the hydraulic system controls the extension and retraction of the hydraulic cylinder. When the hydraulic cylinder retracts, it moves the crushing cone upwards via the connecting sleeve, increasing the distance between the crushing cone and the crushing tank, resulting in larger crushed particles. When the hydraulic cylinder extends, it moves the crushing cone downwards via the connecting sleeve, decreasing the distance between the crushing cone and the crushing tank, resulting in smaller crushed particles. This allows for adjustment of the crushed particle size according to processing requirements. Example
[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problems of cumbersome operation of refeeding larger particles that do not meet the requirements into the crushing mechanism for secondary crushing, and the fact that the use of a screen for screening is prone to screen blockage during use, resulting in ineffective screening and a significant reduction in production efficiency. The overall idea is as follows: To address the problems existing in the prior art, this utility model provides a raw coke crushing and screening device, including a crushing tank 1, a crushing cone 2 rotatably installed inside the crushing tank 1, a sliding groove 13 opened on the crushing cone 2, a second bearing 12 fixedly installed inside the crushing tank 1, a first bevel gear 3 fixedly installed on the outer wall of the second bearing 12, and a transmission rod 7 rotatably installed inside the crushing tank 1.
[0018] A second bevel gear 4 is fixedly installed on the side end of the transmission rod 7, and a reduction gearbox 6 is fixedly installed on the side end of the crushing tank 1. A motor 5 is fixedly installed on the reduction gearbox 6. The gap between the crushing tank 1 and the crushing cone 2 gradually decreases from the outside to the inside. The inner wall of the first bevel gear 3 is stuck in the slide groove 13. The first bevel gear 3 can slide up and down along the slide groove 13. The first bevel gear 3 meshes with the second bevel gear 4.
[0019] The motor 5 drives the transmission rod 7 to rotate through the reduction gearbox 6. A hydraulic cylinder 9 is fixedly installed inside the crushing tank 1. A connecting sleeve 8 is fixedly installed at the end of the telescopic rod of the hydraulic cylinder 9. The inner side wall of the connecting sleeve 8 is fixedly connected to the top of the crushing cone 2. The inner side wall of the first bearing 11 is fixedly connected to the top of the crushing cone 2. A support frame 14 is fixedly installed at the bottom of the crushing tank 1.
[0020] Working principle: The first step, during installation, involves connecting hydraulic cylinder 9 to the hydraulic system, connecting the top opening of crushing tank 1 to the feeding mechanism, and connecting the bottom opening of crushing tank 1 to the output mechanism. During operation, the feeding mechanism feeds larger raw coke material into crushing tank 1. The material falls along the inclined surface of crushing cone 2 into the gap between crushing tank 1 and crushing cone 2. Motor 5 starts and drives transmission rod 7 to rotate via reduction gearbox 6. Reduction gearbox 6 reduces the output speed of transmission rod 7 through its internal reduction gear set, while increasing the output torque. Transmission rod 7 drives first bevel gear 3 to rotate via second bevel gear 4. Because the inner wall of first bevel gear 3 engages the groove 13 on crushing cone 2, first bevel gear 3 drives crushing cone 2 to rotate. The rotation of crushing cone 2 grinds the material falling into the gap between crushing tank 1 and crushing cone 2. In the crushing process, the gap between the crushing tank 1 and the crushing cone 2 gradually decreases from the outside to the inside. Larger materials are trapped near the outside, while smaller materials can continue to move inwards. The gradually narrowing gap between the crushing tank 1 and the crushing cone 2 separates materials of different sizes. Larger materials remain on the outside and are continuously crushed into smaller pieces by the rotating crushing cone 2. These smaller pieces then gradually approach the opening at the bottom of the crushing tank 1 until they become small particles that meet processing requirements. Finally, they are discharged from the opening at the bottom of the crushing tank 1 and enter the conveying mechanism. The process of screening materials of varying sizes through the gradually narrowing gap between the crushing tank 1 and the crushing cone 2, followed by the gradual crushing of the materials into the required particles by the rotating crushing cone 2, not only avoids clogging but also allows for one-time crushing of the raw materials to the required size, thus improving production efficiency.
[0021] The second step involves adjusting the size of the crushed particles by controlling the extension and retraction of the hydraulic cylinder 9 via the hydraulic system. When the extension rod of the hydraulic cylinder 9 retracts, it drives the crushing cone 2 upward through the connecting sleeve 8. At this time, the distance between the crushing cone 2 and the crushing tank 1 increases, and the crushed particles become larger accordingly. When the extension rod of the hydraulic cylinder 9 extends, it drives the crushing cone 2 downward through the connecting sleeve 8. At this time, the distance between the crushing cone 2 and the crushing tank 1 decreases, and the crushed particles become smaller accordingly. During the up-and-down sliding process of the crushing cone 2, due to the first conical teeth... The inner wall of wheel 3 is fixedly connected to the outer wall of the second bearing 12, and the inner wall of the second bearing 12 is fixedly connected to the crushing tank 1. The crushing cone 2 can slide along the slide groove 13. Therefore, the first bevel gear 3 will not move with the crushing cone 2. The first bevel gear 3 can thus always maintain meshing with the second bevel gear 4. The top of the crushing cone 2 is fixedly connected to the inner wall of the first bearing 11, and the outer wall of the first bearing 11 is fixedly connected to the inner wall of the connecting sleeve 8. Therefore, when the first bevel gear 3 drives the crushing cone 2 to rotate, the crushing cone 2 will not drive the connecting sleeve 8 to rotate.
[0022] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
