Technical Field
[0001] This utility model relates to the technical field of iron ore crushing equipment, specifically to an iron ore beneficiation crusher equipped with a dust suppression structure. Background Technology
[0002] Iron ore crushing equipment is a key piece of equipment used to crush large pieces of iron ore to the required particle size, playing a vital role in the iron ore processing flow. During iron ore mining, crushing equipment is required, which generates a large amount of dust. This dust spreads into the air and easily pollutes the environment. Currently, wind-powered dust removal is used to suppress the large amount of dust generated, but the overall energy consumption is high, which is not conducive to energy conservation and emission reduction, and the effect is not good.
[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number CN202021532374.5, application date 2020-07-29) is an iron ore crusher with dust suppression function. By wetting the ore, it can effectively reduce dust generation and avoid the large-scale spread of dust, which would affect the environment.
[0004] After the crusher crushes the iron ore, the crushed iron ore is discharged from the discharge port. Some of the iron ore that is too large cannot be crushed, resulting in a waste of energy. During the operation of the above-mentioned device, vibration cannot be achieved, resulting in a large difference in particle size after crushing, which affects the consistency of product quality, accelerates the wear and damage of the equipment, and reduces the working efficiency of the device. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This iron ore crusher with a dust suppression structure adopts a novel structural design, the specific details of which are as follows:
[0014] (1) The iron ore beneficiation crusher with dust suppression structure, through the set moving column and spring, makes the screen plate vibrate inside the crusher, so that larger iron ore is separated from the inside of the crusher and can be crushed again, thereby ensuring that the iron ore particles after crushing are more uniform and improving the overall crushing efficiency.

[0027] 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 protection scope of the present utility model.
[0028] Example 1: The dust cover 2, crushing component 29, and moving column 26 improve the stability of the device during operation. Figures 1-3 As shown: It includes a crusher 1, a water tank 23 fixedly connected to the surface of the crusher 1, a dust collection component 30 fixedly connected to the surface of the crusher 1, a dust cover 2 fixedly connected to the upper surface of the crusher 1, a motor 3 fixedly connected to the surface of the crusher 1, a first rotating shaft 4 rotatably installed inside the crusher 1, a second rotating shaft 7 rotatably installed inside the crusher 1, and crushing components 29 fixedly connected to the surface of both the second rotating shaft 7 and the first rotating shaft 4, a fixed plate 25 fixedly connected to the inner wall of the crusher 1, a moving column 26 slidably connected inside the fixed plate 25, a screen plate 28 fixedly connected to the surface of the moving column 26, and the surface of the screen plate 28 is inclined, an isolation box 12 fixedly connected to the surface of the crusher 1, a second drive shaft 13 rotatably installed inside the isolation box 12, and a third drive shaft 17 rotatably installed inside the isolation box 12.
[0029] Iron ore is transported into crusher 1 via a conveyor. When motor 3 is working, it drives the first shaft 4 at the output end to rotate. The first gear 5 and the second gear 6 are meshed. Crushing components 29 are installed on the surfaces of the first shaft 4 and the second shaft 7, thereby crushing the iron ore inside crusher 1. During the crushing process, dust generated by dust cover 2 is sprayed by nozzle 21, effectively reducing dust pollution to the air. The dust is absorbed by the dust collection component 30 inside the dust cover 2. Finally, the crushed iron ore is discharged from the discharge port of crusher 1. The dust collection component 30 reduces dust diffusion, improves the working environment, and protects the health of operators.
[0030] In Example 2, unlike Example 1, the working efficiency of the device is improved by incorporating the second cam 16, water pipe 22, and water tank 23. Figures 4-5As shown: A first rotating shaft 4 is fixedly connected to the output end of motor 3, and a first gear 5 is fixedly connected to the surface of the first rotating shaft 4. A third cam 24 is fixedly connected to both the surface of the first rotating shaft 4 and the surface of the second rotating shaft 7. A second gear 6 is fixedly connected to the surface of the second rotating shaft 7, and the second gear 6 is meshed with the first gear 5. A belt 8 is sleeved on the surface of the second rotating shaft 7, and a first drive shaft 10 is sleeved on the other end of the belt 8. The first drive shaft 10 is rotatably mounted inside the dust cover 2. A bevel gear 11 is fixedly connected to both the surface of drive shaft 0 and the surface of drive shaft 13. A fixed frame 20 is movably connected to the surface of drive shaft 13, and drive shaft 17 is movably connected to the other end of the fixed frame 20. A cam 14 is fixedly connected to the surface of drive shaft 13, and a connecting column 15 is fixedly connected to the surface of cam 14. A cam 16 is fixedly connected to the other end of the connecting column 15. A support frame 18 is fixedly connected to the surface of the connecting column 15, and a sliding block 19 is fixedly connected to the surface of the support frame 18.
[0031] The second rotating shaft 7 is connected to the first transmission shaft 10 via belt 8. Both the surface of the first transmission shaft 10 and the surface of the second transmission shaft 13 are equipped with bevel gears 11. When the motor 3 rotates, it drives the second transmission shaft 13 inside the isolation box 12 to rotate. The first cam 14 on the surface of the second transmission shaft 13 is connected to the second cam 16 on the surface of the third transmission shaft 17 via connecting column 15. This causes the support frame 18 on the surface of connecting column 15 to move when the second transmission shaft 13 rotates. The surface of the support frame 18 is equipped with a sliding block 19, which slides on the surface of the fixed frame 20. The nozzle 21 inside the sliding block 19 is connected to the water tank 23 on the surface of the crusher 1 via water pipe 22. This allows the nozzle 21 to slide on the surface of the fixed frame 20, which not only increases the spraying range of the nozzle 21 but also reduces the spread of dust.
[0032] In Example 3, unlike Example 2, the overall crushing efficiency of the device is improved by incorporating the spring 27, the moving column 26, and the screen plate 28. Figures 6-7 As shown: the sliding block 19 is slidably disposed on the surface of the fixed frame 20, and the nozzle 21 is fixedly connected to the surface of the sliding block 19. The water pipe 22 is fixedly connected to the lower surface of the nozzle 21, and the water tank 23 is fixedly connected to the other end of the water pipe 22. The drive shaft 17 is fixedly connected to the surface of the second cam 16. The spring 27 is fixedly connected to the surface of the fixed plate 25, and the moving column 26 is fixedly connected to the other end of the spring 27. The screen plate 28 is in contact with the inner wall of the crusher 1.
[0033] When the No. 1 rotating shaft 4 rotates, the No. 3 cam 24 on its surface will rotate accordingly. When the No. 3 cam 24 contacts the moving column 26, the No. 3 cam 24 will push the screen plate 28 on the surface of the moving column 26 to move in the crusher 1, and cause the spring 27 to contract towards the inner wall of the fixed plate 25. When the No. 3 cam 24 moves away from the moving column 26, the spring 27 will drive the moving column 26 and the screen plate 28 back to the initial position, thereby realizing the vibration of the screen plate 28 inside the crusher 1. Through the vibration of the screen plate 28, larger iron ore after being crushed inside the crusher 1 can be separated from the inside of the crusher 1 and can be crushed again, thereby ensuring that the crushed iron ore has a more uniform particle size and improving the overall crushing efficiency.
[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
