[0002] Bauxite actually refers to the general term for ores that can be utilized industrially and mainly composed of gibbsite and boehmite. The application fields of bauxite include both metal and non-metal aspects. It is the best raw material for producing metallic aluminum and also the main application field, with its consumption accounting for more than 90% of the total world bauxite output. Although the proportion of bauxite used in the non-metal aspect is small, its uses are very extensive. Almost all beneficiation processes are inseparable from grinding. In beneficiation experiments, it is often necessary to measure the grinding fineness of ores, carry out sample preparation work such as crushing, quartering, and grinding of samples, and screen the particles of bauxite samples through a screening device, and then select the particle sizes required for the experiment.

Detailed Embodiment
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-4, the present utility model provides a technical solution: a bauxite screening device, including a screening box 1. The screening box 1 is a hollow box body. The upper end of the screening box 1 is communicated with a feed inlet 7. Inside the screening box 1, three screening plates 11 are slidably connected. The rear end of the screening box 1 is communicated with three moving grooves 12. Inside each of the three moving grooves 12, a moving block 13 is slidably connected. The front ends of the three moving blocks 13 are respectively fixedly connected to the rear ends of the three screening plates 11. Inside each of the three moving grooves 12, a spring 14 is connected. The upper ends of the three springs 14 are respectively connected to the lower ends of the three moving blocks 13. The left ends of the three moving grooves 12 are each slidably connected with a pushing plate 15. The left ends of the three pushing plates 15 are respectively fixedly connected to the right ends of the three moving blocks 13. The lower end of the pushing plate 15 at the uppermost position is fixedly connected with a connecting rod 16. The connecting rod 16 is fixedly connected between the three pushing plates 15. The rear end of the screening box 1 is rotatably connected with a rotating rod 17. The rear end of the screening box 1 is fixedly connected with a braking motor 18 through a bracket. The output end of the braking motor 18 is fixedly connected to the central end of the rotating rod 17. The rotating rod 17 corresponds to the pushing plate 15 at the central end in position. The right end of the screening box 1 is communicated with a storage box 2. The right end of the screening box 1 is provided with three blanking grooves 9. The lower ends of the three blanking grooves 9 respectively correspond to the upper surfaces of the three screening plates 11 in position. The upper end of the screening box 1 is fixedly connected with a cylinder 8. The right end of the screening box 1 is provided with three moving grooves. The output end of the cylinder 8 is fixedly connected with three baffle plates 10. The three baffle plates 10 respectively correspond to the three moving grooves in position. The sizes of the three screening plates 11 are different. The front end of the screening box 1 is provided with a box door, and the box door corresponds to an observation window 6 in position.
[0024] During operation, when it is necessary to screen bauxite, the bauxite is put into the interior of the feed inlet 7, and can enter the interior of the screening box 1 through the feed inlet 7. Since the sizes screened by the three screening plates 11 are different, the bauxite can pass through and be screened by the three screening plates 11. When there is too much bauxite, the brake motor 18 is started. Since the output end of the brake motor 18 is fixedly connected to the rotating rod 17, the rotating rod 17 rotates at the rear end of the screening box 1. When the rotating rod 17 rotates, it can push one of the push plates 15, causing the push plate 15 to move inside the moving groove 12. And since the moving block 13 is fixedly connected to the push plate 15, the moving block 13 drives the three screening plates 11 to move simultaneously inside the screening box 1, enabling the bauxite placed on the screening plates 11 to be screened. When the screening is completed, the air cylinder 8 is started, causing the three baffles 10 to enter the moving groove. Due to the inclination angle of the screening plates 11, the bauxite on the screening plates 11 enters the interior of the storage box 2 for storage. The brake motor 18 is a prior art device with an electromagnetic brake at the tail of the motor. When the motor is powered on, it is also powered on and attracted, and at this time it does not brake the motor. When the motor is powered off, it is also powered off, and the brake holds the motor under the action of the spring.
[0025] Please refer to Figures 1-4 For this, the present utility model provides a technical solution: Two partition plates 19 are fixedly connected to the right end of the storage box 2, and three cabinet doors 3 are movably hinged to the right end of the storage box 2.
[0026] During operation, when it is necessary to take out the interior of the storage box 2, the two partition plates 19 can be used to separately store the materials screened on the three screening plates 11, and the materials inside the storage box 2 can be taken out through the cabinet doors 3.
[0027] Please refer to Figures 1-4 For this, the present utility model provides a technical solution: Four support legs 4 are fixedly connected to the lower end of the screening box 1, and anti-slip pads 5 are fixedly connected to the lower ends of the four support legs 4.
[0028] During operation, the screening box 1 can be placed more stably through the support legs 4 and the anti-slip pads 5.
[0029] Please refer to Figures 1-4 For this, the present utility model provides a technical solution: An observation window 6 is fixedly connected to the front end of the screening box 1.
[0030] During operation, the interior of the screening box 1 can be observed through the observation window 6.
[0031] Please refer to Figures 1-4 For this, the present utility model provides a technical solution: The sizes of the three moving grooves 12 and the three moving blocks 13 are adapted to each other.
[0032] During operation, by adapting the dimensions between the moving slot 12 and the moving block 13, the moving block 13 will not shift during movement.
[0033] Please refer to Figures 1-4 , the present utility model provides a technical solution: a limiting slot 20 is formed in the rear inner wall of the screening box 1, and three limiting blocks are slidably connected inside the limiting slot 20. The three limiting blocks are respectively fixedly connected to the rear ends of the three screening plates 11.
[0034] During operation, due to the fixed connection between the limiting block and the screening plate 11, when the screening plate 11 moves, the movement of the screening plate 11 can be limited.
[0035] Please refer to Figures 1-4 , the present utility model provides a technical solution: handles are fixedly connected to the right ends of the three cabinet doors 3.
[0036] During operation, by fixedly connecting the handle to the cabinet door 3, the cabinet door 3 can be moved more conveniently.
[0037] In summary, when it is necessary to screen bauxite, the bauxite is put into the inside of the feed inlet 7, and then enters the inside of the screening box 1 through the feed inlet 7. Since the screening sizes of the three screening plates 11 are different, the bauxite can pass through and be screened by the three screening plates 11. When there is too much bauxite, the braking motor 18 is started. Since the output end of the braking motor 18 is fixedly connected to the rotating rod 17, the rotating rod 17 rotates at the rear end of the screening box 1. When the rotating rod 17 rotates, one of the push plates 15 is pushed, so that the push plate 15 moves inside the moving slot 12. And because the moving block 13 is fixedly connected to the push plate 15, the moving block 13 drives the three screening plates 11 to move inside the screening box 1 at the same time, so that the bauxite placed on the screening plates 11 can be screened. When the screening is completed, the cylinder 8 is started, so that the three baffles 10 enter the inside of the moving slot. Due to the inclination angle of the screening plate 11, the bauxite on the screening plate 11 enters the inside of the storage box 2 for storage.
