Description

Technical Field

[0001] This utility model relates to the field of bauxite clinker preparation technology, and in particular to equipment for preparing high-quality bauxite clinker. Background Technology

[0002] Bauxite (also known as bauxite or aluminum ore) is a sedimentary rock with aluminum oxide as its main component. It is usually formed by the long-term weathering or chemical deposition of aluminum-bearing minerals (such as gibbsite, boehmite, and diaspore). Its composition is complex and often contains impurities such as oxides of silicon, iron, and titanium. The aluminum content is generally 40%-60%.

[0003] In the process of preparing bauxite clinker, the raw materials need to be crushed in the first step. However, the crushing operation of the crusher often produces some large unqualified crushed materials. Therefore, a device is needed to screen out the large unqualified materials to improve the quality of the collected materials and ensure the effect of subsequent processing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-quality bauxite clinker preparation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-quality bauxite clinker preparation device includes a crushing box with a feed pipe and a discharge pipe. Two symmetrical rotating shafts are rotatably mounted on the crushing box, each with a crushing roller fixedly mounted on it. A spur gear is fixedly mounted at one end of each shaft, and the two spur gears mesh with each other for transmission. A rotary motor is fixedly mounted on the crushing box, and its output shaft is fixedly mounted on one of the spur gears. A sieve screen is slidably installed inside the crushing box. Multiple fixing blocks are fixedly mounted inside the crushing box, each with a spring fixedly mounted on it. Protective plates are fixedly mounted on each spring, and these protective plates are positioned below the sieve screen. A rotating rod is rotatably connected inside the crushing box, with eccentric protrusions fixedly mounted at both ends. The rotating rod is connected to one of the rotating shafts via a belt drive assembly.

[0007] Preferably, the belt drive assembly includes two pulleys fixedly connected to one end of a rotating rod and one of the rotating shafts, and the belt body is mounted on both pulleys for rotation.

[0008] Preferably, the crushing box has a waste inlet, a rotating shaft is rotatably connected to the waste inlet, a baffle plate is fixedly installed on the rotating shaft, a bevel gear is fixedly installed on the rotating shaft, a rotating motor is fixedly installed inside the crushing box, a threaded rod is fixedly installed on the output shaft of the rotating motor, and a push plate is threadedly connected to the threaded rod.

[0009] Preferably, a support platform is fixedly installed at the lower end of the crushing box, and the lower end of the support platform is provided with anti-slip texture.

[0010] Preferably, the crushing chamber has a slot, and the baffle plate is slidably connected in the slot.

[0011] Preferably, a slide rod is slidably connected to the push plate, and the slide rod is fixedly connected inside the crushing chamber.

[0012] 1. Compared with the prior art, the beneficial effects of this utility model are: by starting with a rotary motor, and with the cooperation of two spur gears, the two rotating shafts rotate simultaneously, so that the crushing roller crushes the raw material. At the same time, the belt drive assembly drives the rotating rod and the eccentric protrusion to vibrate the screen. While the screen removes unqualified crushed materials, it can prevent unqualified crushed materials from clogging the screen.

[0013] 2. By rotating the motor to drive the threaded rod to rotate, after the screening work is completed, the push plate can be driven to push the unqualified residue on the screen to the waste inlet. During the process, the first and second bevel gears can open the barrier plate when the push plate moves to the appropriate position, so that the waste can enter and be easily cleaned by the staff.

Detailed Implementation

[0020] Reference Figures 1-5 A high-quality bauxite clinker preparation equipment includes a crushing box 1, a feed pipe 11, a discharge pipe 12, two symmetrical rotating shafts 2 rotatably mounted on the crushing box 1, crushing rollers 3 fixedly mounted on each of the two rotating shafts 2, and spur gears 4 fixedly mounted on one end of each of the two rotating shafts 2. The two spur gears 4 mesh with each other for transmission. A rotary motor 5 is fixedly mounted on the crushing box 1. The rotary motor 5 is existing technology and can rotate an object connected to its output shaft. The output shaft of the rotary motor 5 is fixedly mounted on one of the spur gears 4. A screen 6 is slidably installed inside the crushing box 1. Multiple fixing blocks are fixedly installed inside the crushing box 1. Springs 7 are fixedly mounted on each of the multiple fixing blocks. Protective plates 8 are fixedly mounted on each of the multiple springs 7. The multiple protective plates 8 are all located at the lower end of the screen 6. A rotating rod 9 is rotatably connected inside the crushing box 1. Eccentric protrusions 10 are fixedly mounted on both ends of the rotating rod 9. The rotating rod 9 is connected to one of the rotating shafts 2 through a belt drive assembly.

[0021] The starting of the rotary motor 5 drives a spur gear 4 to rotate, which in turn causes the meshing spur gear 4 to rotate. As a result, the two spur gears 4 drive the two rotating shafts 2 to rotate simultaneously, thereby causing the crushing roller 3 to rotate and perform crushing work. At the same time, the belt drive assembly drives the rotating rod 9 to rotate, which in turn causes the two eccentric protrusions 10 on it to rotate continuously and vibrate the screen 6, causing the screen 6 to rise and fall continuously. This prevents unqualified waste from clogging the screen 6. During this process, the spring 7 and the protective plate 8 support the screen 6 and prevent the screen 6 from being damaged by the impact of falling.

[0022] The belt drive assembly includes two pulleys 13 fixedly connected to one end of the rotating rod 9 and one of the rotating shafts 2, and the belt body 14 is mounted on the two pulleys 13 together for rotation.

[0023] The rotation of a shaft 2 drives the pulley 13 to rotate, which in turn causes the belt body 14 to rotate, thereby driving the other pulley 13 to rotate, which in turn drives the rotating rod 9 to rotate.

[0024] The crushing box 1 has a waste inlet 15, and a rotating shaft is rotatably connected to the waste inlet 15. A baffle plate 16 is fixedly installed on the rotating shaft, and a bevel gear 17 is fixedly installed on the rotating shaft. A rotating motor 18 is fixedly installed inside the crushing box 1. The rotating motor 18 is existing technology and can make the object connected to its output shaft rotate. A threaded rod 19 is fixedly installed on the output shaft of the rotating motor 18. A push plate 20 is threadedly connected to the threaded rod 19, and a bevel gear 21 is fixedly installed on the threaded rod 19. The bevel gear 17 and the bevel gear 21 mesh with each other.

[0025] The motor 18 is started, which drives the threaded rod 19 to rotate. This drives the push plate 20 to move and push the waste material on the screen 6. During this process, the bevel gear 21 on the threaded rod 19 drives the bevel gear 17 to rotate, which causes the rotating shaft to rotate and drives the baffle plate 16 to rotate. When the push plate 20 moves to the appropriate position, the baffle plate 16 opens, and the push plate 20 pushes the waste material into the waste inlet 15. When the baffle plate 16 is closed, it can prevent the raw material from falling into the waste inlet 15 during screening.

[0026] A support platform is fixedly installed at the lower end of the crushing box 1. The lower end of the support platform is equipped with anti-slip texture. The support platform and anti-slip texture allow the device to be stably placed in the designated position. A slot is opened inside the crushing box 1, and the baffle plate 16 is slidably connected in the slot. The baffle plate 16 can be slid into the slot, so it will not interfere with the vibration of the screen 6. A sliding rod is slidably connected to the push plate 20. The sliding rod is fixedly connected in the crushing box 1. The sliding rod stabilizes the push plate 20 so that it will not shake when it moves. At the same time, neither the sliding rod nor the threaded rod 19 interferes with the vibration of the screen 6.

[0027] In this invention, the working principle is as follows: The starting of the rotary motor 5 drives a spur gear 4 to rotate, causing the meshing spur gear 4 to rotate. Therefore, both spur gears 4 drive two rotating shafts 2 to rotate simultaneously, thereby causing the crushing roller 3 to rotate and perform the crushing operation. The rotation of one rotating shaft 2 drives the pulley 13 to rotate, thus causing the belt body 14 to rotate. This, in turn, drives the other pulley 13 to rotate, which in turn drives the rotating rod 9 to rotate. This causes the two eccentric protrusions 10 on the rod to rotate continuously, vibrating the screen 6. This causes the screen 6 to rise and fall continuously, preventing unqualified waste material from clogging the screen 6. During the process, spring 7 and protective plate 8 support the screen 6 to prevent damage from falling impact. The motor 18 is started, which drives the threaded rod 19 to rotate, thus moving the push plate 20 to push the waste on the screen 6. During this process, the bevel gear 21 on the threaded rod 19 drives the bevel gear 17 to rotate, causing the rotating shaft to rotate and driving the barrier plate 16 to rotate. When the push plate 20 moves to the appropriate position, the barrier plate 16 opens, and the push plate 20 pushes the waste into the waste inlet 15. When the barrier plate 16 is closed, it can prevent the raw material from falling into the waste inlet 15 during screening.
