Description

Technical Field

[0001] This utility model relates to the field of raw material screening technology for cement products, and in particular to a raw material screening device for cement product manufacturing. Background Technology

[0002] Cement is a powdery hydraulic inorganic binder that forms a paste when mixed with water. It can harden in air or water and can firmly bind materials such as sand and stone together. During the manufacturing of cement products, the raw materials often need to be screened.

[0003] For example, patent document CN221133041U discloses a reciprocating screening device for raw materials in cement product manufacturing. It includes a fixed base, with support rods at the top of the base, and top panels at the top of the four support rods. A drive motor is located at the top of the fixed base, and an eccentric wheel is located on one side of the drive motor. The device comprises a screening screen, a drive motor, an eccentric wheel, and a connecting rod. The drive motor rotates the eccentric wheel, and the connecting rod converts this rotation into the reciprocating motion of the screen box. Utilizing the inclination angle of the screening screen and the weight of the material, the device achieves material screening. An auxiliary rod assists in the reciprocating oscillation of the screen box. After cement products enter the screen box, they are screened by the screening screen. Smaller particles fall to the bottom first, and larger particles fall further down, thus separating the raw materials into different sizes for collection, facilitating the production of cement products.

[0004] However, the vibration mode of this device is relatively simple, which makes it difficult to guarantee the screening effect and also results in low cleaning efficiency when encountering blockages. Utility Model Content

[0005] The purpose of this invention is to provide a raw material screening device for cement product manufacturing in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A raw material screening device for cement product manufacturing includes a shell, which is inclined. A sorting mechanism is provided on the shell, including a coarse filter plate fixedly connected to the inner wall of the shell. A fine filter plate is fixedly connected to the inner surface of the shell and located below the coarse filter plate. A vibration mechanism is provided on the fine filter plate, including a vibration box fixedly connected to the fine filter plate. The top of the vibration box is fixedly connected to the bottom of the coarse filter plate. A limit post is slidably connected to the inner surface of the vibration box. A rack is fixedly connected to both sides of the limit post. A gear meshes with the bottom of the rack at the higher position and another gear meshes with the top of the rack at the lower position. A driven rod meshes with the side of the gear away from the center of the vibration box. Impact blocks are fixedly connected to the top and bottom of the driven rod. A shock-absorbing mechanism is provided at the bottom of the shell, and a support is provided on the shock-absorbing mechanism. An eccentric mechanism is provided at the bottom of the shell to drive the shell to vibrate in the horizontal direction. A feeding mechanism is provided at the top of the shell.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-7 As shown, a raw material screening device for cement product manufacturing includes a housing 1, which is inclined. A sorting mechanism is provided on the housing 1, including a coarse filter plate 601 fixedly connected to the inner wall of the housing 1. A fine filter plate 602 is fixedly connected to the inner surface of the housing 1, located below the coarse filter plate 601. A vibration mechanism is provided on the fine filter plate 602, including a vibration box 701 fixedly connected to the fine filter plate 602. The top of the vibration box 701 is fixedly connected to the bottom of the coarse filter plate 601. A limit post 702 is slidably connected to the inner surface of the vibration box 701. A rack 703 is fixedly connected to both sides of the limit post 702. A gear 704 meshes with the bottom of the higher rack 703, and another gear 704 meshes with the top of the lower rack 703. 4. A driven rod 705 is meshed on the side of the gear 704 away from the center of the vibrating box 701. Impact blocks 706 are fixedly connected to the top and bottom of the driven rod 705. When the vibrating box 701 vibrates, it will drive the limiting post 702 and the rack 703 to move left and right inside the vibrating box 701. When the limiting post 702 and the rack 703 move to one side, the gear 704 at the lower position will rotate counterclockwise and drive the driven rod 705 and the impact block 706 on the same side to move downward, so that the impact block 706 on the same side will hit the bottom of the vibrating box 701 to generate vertical vibration and transmit the vibration to the fine filter plate 602. A shock-absorbing mechanism is provided at the bottom of the housing 1, and a bracket 3 is provided on the shock-absorbing mechanism. An eccentric mechanism is provided at the bottom of the housing 1. The eccentric mechanism is used to drive the housing 1 to vibrate in the horizontal direction. A feeding mechanism is provided at the top of the housing 1.

[0028] The shock absorption mechanism includes several supports 201, all of which are fixedly connected to the bottom of the housing 1. A connecting block 202 is slidably connected to the bottom of the support 201. A damping rod 203 is fixedly connected to the bottom of the connecting block 202. A spring 204 is fixedly connected to the bottom of the connecting block 202. Support legs 205 are fixedly connected to the bottom of both the damping rod 203 and the spring 204. Support legs 205 are fixedly connected to the bracket 3. The vertical vibration generated will be transmitted to the connecting block 202. The vertical vibration of the connecting block 202 will compress the spring 204 and the damping rod 203. The compression of the spring 204 and the damping rod 203 will absorb the vibration to ensure the stability of the support legs 205. The stability of the support legs 205 will also ensure the stability of the bracket 3.

[0029] The eccentric mechanism includes two support plates 401. A fixed rod 402 is fixedly connected to the opposite surface of the support plates 401. A motor 403 is fixedly connected to the fixed rod 402. A rotating shaft 404 is fixedly connected to the output end of the motor 403. An eccentric wheel 405 is fixedly connected to the top of the rotating shaft 404. The outer surface of the eccentric wheel 405 is slidably connected to the bottom of the housing 1. The motor 403 drives the rotating shaft 404 to rotate. The rotation of the rotating shaft 404 drives the eccentric wheel 405 to rotate. The rotation of the eccentric wheel 405 drives the housing 1 to vibrate in the horizontal direction.

[0030] The feeding mechanism includes a fixed ring 502, which is fixedly connected to the bracket 3. A hopper 501 is fixedly connected to the fixed ring 502. A feeding pipe 503 is slidably connected to the bottom of the hopper 501. The bracket 3 is stable, which also ensures the stability of the hopper 501. The stability of the hopper 501 can prevent cement raw materials from splashing when poured into the hopper 501, thus affecting the feeding process.

[0031] The fitting clearance between the support 201 and the connecting block 202, the eccentric wheel 405 and the bottom of the housing 1, and the hopper 501 and the discharge pipe 503 is consistent with the eccentric radius of the eccentric wheel 405, so as to avoid collision between parts caused by inconsistent clearance and affect the normal use of the device.

[0032] The sorting mechanism includes a first discharge pipe 603, which is fixedly connected to the lower rear end of the housing 1. A second discharge pipe 604 is fixedly connected to the lower side of the housing 1, and a third discharge pipe 605 is fixedly connected to the lower front end of the housing 1. As the housing 1 vibrates, the fine filter plate 602 and the coarse filter plate 601 also vibrate. The vibration of the fine filter plate 602 and the coarse filter plate 601 sorts the raw materials poured into the housing 1. The larger particles of the raw materials will be blocked by the coarse filter plate 601 and discharged from the housing 1 through the first discharge pipe 603. The remaining raw materials will continue to fall down onto the fine filter plate 602. The smaller particles of the raw materials will be blocked by the fine filter plate 602 and discharged from the housing 1 through the second discharge pipe 604. Finally, the finest particles of the raw materials will fall down again through the fine filter plate 602 to the bottom of the inner wall of the housing 1 and be discharged from the housing 1 through the third discharge pipe 605, thus completing the screening of cement raw materials.

[0033] Working principle: When using this device, the operator first drives the motor 403, which drives the rotating shaft 404 to rotate. The rotation of the rotating shaft 404 drives the eccentric wheel 405 to rotate, and the rotation of the eccentric wheel 405 drives the housing 1 to vibrate in the horizontal direction. At this time, cement raw materials are poured into the housing 1 through the hopper 501. The vibration of the housing 1 causes several supports 201 to vibrate. Since the fit clearance between the support 201 and the connecting block 202 is consistent with the eccentric radius of the eccentric wheel 405, the vibration of the support 201 will not drive the connecting block 202. 02. Horizontal vibration is generated, and the resulting vertical vibration is transmitted to the connecting block 202. The vertical vibration of the connecting block 202 will compress the spring 204 and the damping rod 203. The compression of the spring 204 and the damping rod 203 will absorb the vibration to ensure the stability of the support leg 205. The stability of the support leg 205 will also ensure the stability of the bracket 3. The stability of the bracket 3 will also ensure the stability of the hopper 501. The stability of the hopper 501 can prevent the cement raw materials from splashing when they are poured into the hopper 501, which would affect the feeding process.

[0034] As the shell 1 vibrates, the fine filter plate 602 and the coarse filter plate 601 also vibrate. The vibration of the fine filter plate 602 and the coarse filter plate 601 will sort the raw materials poured into the shell 1. The larger particles of raw materials will be blocked by the coarse filter plate 601 and discharged from the shell 1 through the first discharge pipe 603. The remaining raw materials will continue to fall down onto the fine filter plate 602. The smaller particles of raw materials will be blocked by the fine filter plate 602 and discharged from the shell 1 through the second discharge pipe 604. Finally, the finest particles of raw materials will fall down again through the fine filter plate 602 to the bottom of the inner wall of the shell 1 and be discharged from the shell 1 through the third discharge pipe 605, thus completing the screening of cement raw materials.

[0035] While the housing 1 vibrates, the fine filter plate 602 and the coarse filter plate 601 drive the vibrating box 701 to vibrate. The vibration of the vibrating box 701 causes the limiting post 702 and the rack 703 to move left and right inside the vibrating box 701. When the limiting post 702 and the rack 703 move away from the first discharge pipe 603, the gear 704 at the lower position will rotate counterclockwise and drive the driven rod 705 and the impact block 706 on the same side to move downward, so that the impact block 706 on the same side hits the bottom of the vibrating box 701 to generate vertical vibration, and transmits the vibration to the fine filter plate 601. On filter plate 602, the gear 704 at the top rotates clockwise and drives the driven rod 705 and impact block 706 on the other side to move upward, causing the impact block 706 on the other side to strike the top of the vibrating box 701 and generate vertical vibration, which is then transmitted to the coarse filter plate 601. When the limiting column 702 and the rack 703 move to the other side, this process is repeated in mirror image, and the impact on the fine filter plate 602 and the coarse filter plate 601 is continuous, preventing the raw material from clogging the fine filter plate 602 and the coarse filter plate 601 and affecting the screening of cement raw materials.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
