Description
Technical Field
[0001] This utility model relates to the field of soil screening technology, specifically a kaolin precision particle size classification device. Background Technology
[0002] Kaolin is a natural clay mineral with kaolinite as its main component. It has a white or light gray fine texture and naturally occurs as loose soil or dense blocks. It has good plasticity, binding properties and chemical stability.
[0003] The process of processing kaolin begins with mining the raw materials, followed by crushing them. The crushed kaolin particles are then fed into a mill for fine grinding. Through agitation and other methods, the kaolin particles are fully dispersed in the slurry. Impurities are then removed from the kaolin, and finally, it is screened to separate it into products of different particle sizes. The graded kaolin of different particle sizes is then collected by corresponding collection devices for subsequent testing and packaging.
[0004] In existing kaolin grading processes, the initial screening operation is not ideal, requiring multiple screenings, which is quite cumbersome. Therefore, a precise particle size classification device for kaolin is proposed to address the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Specific implementation examples are given below.
[0024] like Figures 1 to 5As shown in the figure, a kaolin precision particle size classification device according to an embodiment of the present invention includes a container 1; a feed inlet 11 is provided at the top of the container 1; multiple sets of first fixing seats 12 are fixedly connected to the inner side wall of the container 1; a first screening screen 13 is connected to the side wall of the first fixing seat 12 by a torsion spring; multiple sets of first round holes 14 are provided at the top of the first screening screen 13; a first fixing seat 12 is fixedly connected to the top of the container 1; a second screening screen 15 is connected to the side wall of the first fixing seat 12 by a torsion spring; multiple sets of second round holes 16 are provided at the top of the second screening screen 15; a first fixing seat 12 is fixedly connected to the bottom of the container 1; a third screening screen 17 is rotatably connected to the side wall of the first fixing seat 12; multiple sets of second round holes 16 are provided at the top of the third screening screen 17. Three circular holes 18; multiple sets of second fixed seats 19 are fixedly connected to the side wall of the container 1; a first electric push rod 110 is fixedly connected to the side wall of the second fixed seat 19; a rotating wheel 111 is rotatably connected to the top of the first electric push rod 110; the rotating wheel 111 is slidably arranged with the first screening screen 13, the second screening screen 15, and the third screening screen 17; multiple sets of discharge ports 112 are opened on the side wall of the container 1; the discharge ports 112 are correspondingly arranged with the first screening screen 13, the second screening screen 15, and the third screening screen 17; during operation, pushing the first electric push rod 110 drives the rotating wheel 111 to rotate and contact the first screening screen 13, the second screening screen 15, and the third screening screen 17, adjusting the tilt angle of the first screening screen 13, the second screening screen 15, and the third screening screen 17. The raw materials are fed into the container 1 through the inlet 11. The raw materials entering the container 1 through the inlet 11 first pass above the first screening screen 13. Larger materials remain on the surface of the first screening screen 13. The first screening screen 13 is tilted, causing the larger materials to fall into the side outlet 112. Smaller materials fall from the center of the first circular hole 14 onto the surface of the second screening screen 15. Materials larger than the surface of the second circular hole 16 remain above the second screening screen 15. The second screening screen 15 is tilted, causing the larger materials to fall into the corresponding outlet 112. Materials smaller than the second circular hole 16 fall onto the surface of the third screening screen 17. Materials larger than the second fixed base 19 fall into the outlet 112. Materials smaller than the second fixed base 19... The material falls into the bottom of container 1 and is connected to the first screening screen 13 by a torsion spring through the first fixed seat 12. The first screening screen 13 applies a downward pushing force, so that the first screening screen 13 and the rotating wheel 111 always keep in contact. The rotating wheel 111 always applies a pushing force to the first screening screen 13, pushing the first electric push rod 110 to adjust the inclination of the first screening screen 13, the second screening screen 15, and the third screening screen 17, thereby improving the screening effect and making the raw material flow evenly and stably on the first screening screen 13, the second screening screen 15, and the third screening screen 17, reducing material blockage caused by poor material flow. For raw materials of different sizes, the inclination can be adjusted by pushing the first electric push rod 110, so that container 1 can adapt to a variety of raw materials of different sizes and make the screening of raw material flow more precise.
[0025] like Figure 1 and Figure 3 As shown, a support frame 2 is fixedly connected to the top of the container 1; a second electric actuator 21 is fixedly connected to the side wall of the support frame 2; a baffle 22 is fixedly connected to the top of the second electric actuator 21; the baffle 22 is slidably connected to the feed inlet 11; during operation, as the raw material enters the feed inlet 11, it can push the second electric actuator 21 to move the baffle 22 forward, controlling the size of the feed inlet 11. By tilting the baffle 22, the raw material entering the feed inlet 11 can be moved to one end by tilting at an angle. The second electric actuator 21 is adjusted... The size of the feed inlet 11 can control the speed at which the raw material enters the container 1 device. After the inclination of the first screening screen 13, the second screening screen 15, and the third screening screen 17 are adjusted, the size of the feed inlet 11 is adjusted in conjunction with the second electric push rod 21 to achieve a suitable feeding speed. This allows the raw material to be evenly distributed on the first screening screen 13, the second screening screen 15, and the third screening screen 17, reducing local blockage caused by excessive feeding and affecting screening accuracy. It can also prevent the feed inlet 11 from feeding too slowly and flexibly adjust the feeding amount and screening.
[0026] like Figure 2 As shown, multiple sets of third fixed seats 3 are fixed to the side wall of the container 1; an electric striking rod 31 is fixed to the top of the third fixed seat 3; during operation, when the raw material is screened on the first screening screen 13, pushing the electric striking rod 31 can strike it, vibrating the raw material accumulated above the first screening screen 13. When the first electric push rod 110 pushes the first screening screen 13 upward, the electric striking rod 31, being relatively long, can also continue to strike the first screening screen 13. The vibration generated by the electric striking rod 31 continuously striking the first screening screen 13 can loosen and drop the raw material stuck in the first round hole 14 of the screen, keeping the first round hole 14 unobstructed, maintaining stable screening, and reducing the accumulation of raw material on the first screening screen 13. The vibration generated by the electric striking rod 31 can disperse the agglomerated raw material, allowing the dispersed raw material to pass through the first round hole 14.
[0027] like Figures 1 to 5 As shown, a pair of slide rails 4 are fixedly connected to the bottom of the container 1; a collection box 41 is slidably connected to the top of the slide rails 4; a handle 42 is fixedly connected to the side wall of the collection box 41; during operation, the raw materials falling from the third screening screen 17 fall into the collection box 41. When a lot of raw materials accumulate inside the collection box 41, a pulling force is applied to the handle 42, which drives the collection box 41 and the slide rails 4 to slide and connect, pulling out the collection box 41 and grading the raw materials inside the collection box 41. Then, the collection box 41 is placed on the slide rails 4 and slidably connected back to its original position. The last layer of raw materials can be collected and graded through the collection box 41. The sliding connection between the collection box 41 and the slide rails 4 increases the convenience of taking out the collection box 41, reduces the direct friction between the collection box 41 and the bottom of the container 1 when it is picked up or placed, and reduces the scratches on the bottom of the container 1 caused by the direct friction between the collection box 41 and the bottom of the container 1, thus improving the flexibility and convenience of operation.
[0028] like Figure 3 As shown, a first rubber pad 5 is fixedly connected to the top of the first electric push rod 110; a second rubber pad 51 is fixedly connected to the top of the electric striking rod 31. During operation, when the raw material is screened inside the container 1, some of the raw material will fall onto the top of the first electric push rod 110. During the pushing process, the first electric push rod 110 will bring the raw material into the interior. The first rubber pad 5 can clean the raw material on the surface of the first electric push rod 110 during the pushing process. When the electric striking rod 31 strikes the first screening screen 13, the second rubber pad 51 can reduce the direct contact between the electric striking rod 31 and the first screening screen 13. The first rubber pad 5 cleans the material in time, reducing the amount of raw material on the surface of the first electric push rod 110 entering the interior of the first electric push rod 110, thus increasing the stability of the first electric push rod 110. When the electric striking rod 31 contacts the first screening screen 13, it will generate a lot of noise. The second rubber pad 51 can buffer the impact force and reduce the noise generation.
[0029] like Figures 4 to 5 As shown, multiple sets of dustproof cloths 6 are fixed to the side wall of the container 1; the dustproof cloths 6 are correspondingly arranged with the discharge port 112; during operation, the raw material after being screened by the first screening screen 13 falls from the discharge port 112. A large amount of dust is generated when the raw material falls and is classified. The dustproof cloths 6 can block the spread of dust. The dustproof cloths 6 can effectively reduce the dust generated during screening of raw materials from entering the air, reduce the dust concentration around the container 1, and keep the area around the container 1 clean.
[0030] Working principle: The first electric actuator 110 drives the rotating wheel 111 to rotate and contact the first screening screen 13, the second screening screen 15, and the third screening screen 17. The tilt angle of the first screening screen 13, the second screening screen 15, and the third screening screen 17 is adjusted. The raw material is added from the feed inlet 11. The raw material entering the container 1 from the feed inlet 11 first enters above the first screening screen 13. Larger raw materials stay on the surface of the first screening screen 13. The first screening screen 13 is tilted, and the larger raw materials tilt and fall into the side discharge port 112. Smaller raw materials fall from the middle of the first round hole 14 into the surface of the second screening screen 15. Raw materials larger than the surface area of the second circular hole 16 remain above the second screening screen 15. The second screening screen 15 tilts, causing the larger raw materials to fall into the corresponding discharge port 112. Raw materials smaller than the second circular hole 16 fall onto the surface of the third screening screen 17. Raw materials larger than the second fixed seat 19 fall into the discharge port 112, and raw materials smaller than the second fixed seat 19 fall into the bottom of the container 1. During the process of the raw materials entering the feed inlet 11, the second electric push rod 21 can be pushed to move the baffle 22 forward, controlling the size of the feed inlet 11. When the raw materials are screened on the first screening screen 13, the electric impact is pushed. Rod 31 can strike the material, vibrating the material accumulated above the first screening screen 13. When the first electric push rod 110 pushes the first screening screen 13 upward, the long electric striking rod 31 can also continue to strike the first screening screen 13. The material falling from the third screening screen 17 falls into the collection box 41. When there is a lot of material accumulated inside the collection box 41, a pulling force is applied to the handle 42, causing the collection box 41 to slide and connect with the slide rail 4, pulling out the collection box 41, classifying the material inside the collection box 41, and then placing the collection box 41 on the slide rail 4 and sliding it back to its original position. When the raw material is screened inside container 1, some of the raw material will fall to the top of the first electric push rod 110. During the pushing process, the first electric push rod 110 will bring the raw material into the interior. The first rubber pad 5 can clean the raw material on the surface of the first electric push rod 110 during the pushing process. When the electric striking rod 31 strikes the first screening screen 13, the second rubber pad 51 can reduce the direct contact between the electric striking rod 31 and the first screening screen 13. The raw material screened by the first screening screen 13 falls from the discharge port 112. A large amount of dust will be generated when the raw material falls and is classified. The dustproof cloth 6 can block the spread of dust.

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.
