Description

Technical Field

[0001] This utility model relates to the field of kaolin production technology, and in particular to a screening device for kaolin production. Background Technology

[0002] Kaolin, as an important non-metallic mineral raw material, is widely used in various industrial fields such as ceramics, papermaking, coatings, and rubber due to its excellent plasticity, refractoriness, and chemical stability. In the production and processing of kaolin, screening is the core process that determines the particle size distribution and purity of the product, directly affecting the application performance and market value of subsequent products. Therefore, efficient and precise screening equipment has become a key piece of equipment for kaolin producers to enhance their competitiveness.

[0003] Existing screening devices use vertical vibration mechanisms to improve the screening efficiency of kaolin, further enhancing screening efficiency and ensuring that low-particle-size products pass through the underside of the screen. However, due to the large weight of the screening device itself, and the added weight of the kaolin material inside, the vertical vibration structure struggles to guarantee the stability of the screening box during vertical vibration. Furthermore, the vibrating structure, subjected to significant weight, is easily damaged. Utility Model Content

[0004] This utility model provides a screening device for kaolin production, which solves the technical problem that the vibration mechanism of existing screening devices is easily damaged during the screening of kaolin.

[0005] To achieve this technical objective, the present invention adopts the following solution: a screening device for kaolin production, comprising a feeding mechanism, a screening mechanism, a transverse swaying mechanism, and a worktable; A lateral swaying mechanism is installed on the worktable to provide lateral power to the screening mechanism; The screening mechanism is reciprocatingly mounted on the worktable and is connected to the transverse swaying mechanism for screening kaolin. The feeding mechanism is installed on and connected to the screening mechanism, and is used to supply material to the screening mechanism.

[0006] Furthermore, two symmetrically arranged vertical plates are fixed on the top surface of the workbench; The top surface of the workbench is also fixed with two symmetrically arranged rails that are perpendicular to the vertical plate.

[0007] Furthermore, the screening mechanism includes a screening box, support legs, connecting plate, track wheels, and screen; The screening box is tilted on the workbench, the feeding mechanism is located on the top surface of the high end of the screening box, and the bottom side wall of the screening box has upper and lower distributed discharge ports for the oversize product and the undersize product. The screen is fixed horizontally in the middle of the screening box; The top of the support leg is fixedly connected to the bottom of the screening box, and the bottom of the support leg is suspended above the worktable. The two ends of the connecting plate are respectively fixed to two adjacent support legs; The track wheel is rotatably mounted on the connecting plate and slidably mounted on the track.

[0008] Furthermore, the oversize product outlet is located above the screen, and the outside of the oversize product outlet is connected to a first discharge channel. The first discharge channel is fixedly connected to the screening box, and the first discharge port of the first discharge channel extends away from the screening box.

[0009] Furthermore, the undersize product outlet is located below the screen, and a second discharge channel is connected to the outside of the undersize product outlet. The second discharge channel is fixedly connected to the screening box, and the middle of the second discharge channel is higher than both ends. A second discharge port is opened at each end of the second discharge channel.

[0010] Furthermore, the lateral swaying mechanism includes a plug rod, a spring, a push plate, and a single-acting pneumatic push rod; Each support leg has a fixed rod at its bottom, which can be slidably inserted into the vertical plate; The spring is sleeved on the outside of the insertion rod, and the two ends of the spring abut against the vertical plate and the support leg, respectively; The push plate is fixedly connected to two support legs at both ends, and the push plate is set parallel to the vertical plate; The fixed end of the single-acting pneumatic push rod is fixed on the worktable, and the movable end abuts against the push plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses a screening device for kaolin production, which replaces the vertical vibration mechanism in traditional screening devices with a horizontal shaking mechanism. The horizontal shaking mechanism does not need to directly bear the weight of the screening mechanism during the shaking process, thereby preventing the weight of the screening mechanism and the kaolin raw material from acting directly on the horizontal shaking mechanism. This makes the external force borne by the horizontal shaking mechanism much less than that borne by the existing vertical vibration mechanism, thus improving the service life of the horizontal shaking mechanism. At the same time, the horizontal shaking mechanism can shake the screening mechanism, further causing the kaolin raw material to shake on the screen, thereby ensuring the screening efficiency of the kaolin raw material.

[0012] By setting up a first and second discharge channel with a specific shape, the discharge positions of the oversize and undersize products can be distinguished, making it easier to collect the oversize and undersize products separately. Attached Figure Description

[0015] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0016] like Figures 1-2 As shown, this utility model discloses a screening device for kaolin production, including a feeding mechanism 1, a screening mechanism 2, a transverse swaying mechanism 3, and a worktable 4. The lateral swaying mechanism 3 is mounted on the worktable 4 and is used to provide lateral power to the screening mechanism 2; The screening mechanism 2 is reciprocatingly mounted on the workbench 4 and is connected to the transverse swaying mechanism 3 for screening kaolin. The feeding mechanism 1 is installed on the screening mechanism 2 and is connected to the screening mechanism 2, and is used to feed materials to the screening mechanism 2.

[0017] Furthermore, two symmetrically arranged vertical plates 41 are fixed on the top surface of the workbench 4; The top surface of the workbench 4 is also fixed with two symmetrically arranged rails 42 that are perpendicular to the vertical plate 41.

[0018] Furthermore, the screening mechanism 2 includes a screening box 21, a support leg 22, a connecting plate 23, a track wheel 24, and a screen 25; The screening box 21 is inclined on the workbench 4, the feeding mechanism 1 is located on the top surface of the high end of the screening box 21, and the side wall at the bottom end of the screening box 21 has an upper and lower distributed discharge port 211 for the oversize product and a lower screen product discharge port 212. The screen 25 is horizontally fixed in the middle of the screening box 21; The top of the support leg 22 is fixedly connected to the bottom of the screening box 21, and the bottom of the support leg 22 is suspended above the worktable 4. The two ends of the connecting plate 23 are respectively fixed on two adjacent support legs 22; The track wheel 24 is rotatably mounted on the connecting plate 23 and slidably mounted on the track 42.

[0019] Furthermore, the oversize product outlet 211 is located above the screen 25, and the outside of the oversize product outlet 211 is connected to a first discharge channel 26. The first discharge channel 26 is fixedly connected to the screening box 21, and the first discharge port 261 of the first discharge channel 26 extends away from the screening box 21.

[0020] Furthermore, the undersize product outlet 212 is located below the screen 25, and the undersize product outlet 212 is connected to a second discharge channel 27. The second discharge channel 27 is fixedly connected to the screening box 21. The middle part of the second discharge channel 27 is higher than both ends, and a second discharge port 271 is opened at each end of the second discharge channel 27.

[0021] Furthermore, the lateral swaying mechanism 3 includes a rod 31, a spring 32, a push plate 33, and a single-acting pneumatic push rod 34; Each support leg 22 has a fixed insertion rod 31 at its bottom, and the insertion rod 31 is slidably inserted into the vertical plate 41. Spring 32 is sleeved on the outside of insert rod 31, and the two ends of spring 32 abut against vertical plate 41 and support leg 22 respectively; The two ends of the push plate 33 are fixedly connected to the two support legs 22 respectively, and the push plate 33 is set parallel to the vertical plate 41; The fixed end of the single-acting pneumatic push rod 34 is fixed on the worktable 4, and the movable end abuts against the push plate 33.

[0022] In operation, first activate the single-acting pneumatic push rod 34. The single-acting pneumatic push rod 34 extends and contacts the push plate 33. As it extends further, the single-acting pneumatic push rod 34 pushes the push plate 33, compressing the spring 32 at one end. After compression to an appropriate degree, disconnect the power and air supply to the single-acting pneumatic push rod 34, which quickly springs back to its original position. The compressed spring 32 returns to its original position, thereby pushing the support leg 22 to move, ultimately causing the track wheel 24 to slide on the track 42. Under inertia, the spring 32 at the other end is compressed and then returns to its original length. During the repeated compression and return to original length of the springs 32 on both sides, the screening mechanism 2 shakes on the worktable 4. When the shaking amplitude is small, the single-acting pneumatic push rod 34 can be activated again. During the shaking process, kaolin raw material is added into the screening box 21 through the feeding mechanism 1, thus completing the kaolin screening work.
