Description

Technical Field

[0001] The utility model relates to the technical field of iron tailings beneficiation, in particular to a beneficiation device for the recycling of iron-containing tailings. Background Art

[0002] Iron tailings are waste materials after beneficiation and are the main component of industrial solid waste. According to incomplete statistics, the tailings and waste rocks discharged worldwide each year are more than 10 billion tons. There are more than 8,000 state-owned mines and more than 110,000 township collective mines in China. The accumulated tailings volume is nearly 5 billion tons, and the annual discharged tailings volume is as high as more than 500 million tons, of which the annual discharged tailings volume of ferrous metallurgy mines reaches 150 million tons.

[0003] For example, the Chinese patent authorization announcement number CN220804278U discloses a multifunctional beneficiation device, belonging to the technical field of beneficiation devices. It includes a beneficiation device body. Above the interior of the beneficiation device body, there is a washing component. Below the washing component, there is a screen. Below the screen, there is a vibration screening component. Above the beneficiation device body, there is a crushing component. On one side of the crushing component, there is a dust suction component. By setting the vibration screening component in the utility model, the effect of facilitating the vibration screening of ores is achieved, so that when the device is in use, it is convenient to perform vibration screening on the ores, improving the practicality of use. By setting the dust suction component in the utility model, by starting the exhaust fan, the exhaust fan collects the dust into the dust suction chamber through the conveying pipe and the dust collection cover, so that when the device is in use, it is convenient to collect and process the dust flying out of the feed hopper when crushing the ores, avoiding the phenomenon of dust flying everywhere and polluting the surrounding environment.

[0004] By checking the above comparison documents, it can be seen that in the prior art, since a large amount of dust is generated during the crushing process of iron-containing tailings ores, the dust flying into the air will cause air pollution. Therefore, the treatment of dust is particularly crucial. And when vibrating and screening the ores through the screen, the vibration of each screen needs to be driven by a motor. When the number of screens is large, a corresponding large number of motors need to work together. Due to the large amount of motor usage, the beneficiation cost will increase. Summary of the Utility Model

[0005] The utility model provides a beneficiation device for the recycling of iron-containing tailings, which is beneficial to the dust suppression treatment of dust and is beneficial to saving the beneficiation cost.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A beneficiation device for the recycling of iron-containing tailings includes a screening box and a feed hopper, and the feed hopper is arranged above the screening box;

[0008] A crushing box is connected between the screening box and the feed hopper. A crushing roller is arranged in the crushing box.

[0011] Further, a water tank is fixedly arranged at the upper left end of the screening box. A water pump is connected to the water tank. The water outlet of the water pump is connected to the annular pipe.

[0012] Further, the screening apertures of the three sieve meshes decrease sequentially from top to bottom.

Detailed implementation manners

[0024] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the drawings. The content mentioned in the implementation manners does not limit the present utility model.

[0025] As Figures 1-4 shown, in this embodiment, it includes a screening box 1 and a feed hopper 2. The feed hopper 2 is arranged above the screening box 1. A crushing box 3 is communicated between the screening box 1 and the feed hopper 2. A crushing roller 8 is arranged in the crushing box 1. The upper end of the periphery of the feed hopper 2 is fixedly sleeved with an annular pipe 4. The upper end of the annular pipe 4 is communicated with a plurality of atomizing nozzles 5. A vibration box 9 with an open upper end is arranged in the screening box 1. A motor 10 is fixed at the upper right end of the screening box 1. The power end of the motor 10 is connected to a drive shaft 15. The right end of the crushing roller 8 is fixedly provided with a synchronous shaft 12. The synchronous shaft 12 rotates rightward and penetrates through the right side of the crushing box 3. Pulley 11s are fixedly arranged on the outer periphery of the right end of the synchronous shaft 12 and the drive shaft 15, and the two pulley 11s are connected by a belt. A water tank 6 is fixed at the upper left end of the screening box 1. A water pump 7 is communicated with the water tank 6. The water outlet of the water pump 7 is communicated with the annular pipe 4.

[0026] First, the iron-tailings-containing ore is put into the feed hopper 2 and the crushing box 3. The motor 10 works to drive the drive shaft 15, pulley 11, synchronous shaft 12 and crushing roller 8 to rotate together. While the crushing roller 8 crushes the iron tailings, the water pump 7 pumps the water in the water tank 6 into the annular pipe 4 and the atomizing nozzles 5. When the dust generated during crushing floats out from the feed hopper 2, the atomizing nozzles 5 atomize and spray water around the feed hopper 2. The water sprayed by the atomizing nozzles 5 will perform dust suppression treatment on the dust. Therefore, it is beneficial to perform dust suppression treatment on the dust generated by crushing, thereby reducing the pollution of dust to the air and ensuring the environmental quality during work.

[0027] As Figure 2 , 4 shown, in this embodiment, a plurality of springs 14 are connected between the lower end and the outer side wall of the vibration box 9 and the inner wall of the screening box 1, and at least three inclined screen meshes 18 are fixedly arranged in the vibration box 9 from top to bottom. The driving shaft 15 rotates leftward and penetrates into the screening box 1. First semi-circular convex blocks 16 are fixedly arranged at both the upper and lower ends of the driving shaft 15 inside the screening box 1. Second semi-circular convex blocks 17 are fixedly arranged on both sides of the upper end of the vibration box 9, and the first semi-circular convex blocks 16 correspond to the second semi-circular convex blocks 17. The screening apertures of the three screen meshes 18 gradually decrease from top to bottom.

[0028] When the driving shaft 15 rotates, it will drive the first semi-circular convex blocks 16 to rotate. The first semi-circular convex blocks 16 will impact the second semi-circular convex blocks 17 through the arc surface. Therefore, the second semi-circular convex blocks 17 will push the vibration box 9 downward. The vibration box 9 will compress or stretch the springs 14. Combining with the elastic force of the springs 14, it will drive the vibration box 9 and the screen meshes 18 to vibrate together. So the screening efficiency of the screen meshes 18 for the ore can be improved. Moreover, at least three screen meshes 18 are provided, and the screening apertures of the three screen meshes 18 gradually decrease from top to bottom. So it is beneficial to perform multi-stage screening on multiple ores and is conducive to screening out ores of various specifications. And the vibration of the screen meshes 18 and the rotation of the crushing rollers 8 are both driven by the same motor 10. Compared with the prior art that requires multiple motors 10 to drive, this solution effectively reduces the number of motors 10 used, thereby saving the ore dressing cost.

[0029] As Figure 1 shown, in this embodiment, electromagnetic discharge valves 19 communicating with the left side of the vibration box 9 are provided at the left ends of the screen meshes 18. The discharge ports of the electromagnetic discharge valves 19 are all communicated with discharge hoses 20. The discharge hoses 20 all penetrate out of the screening box 1. An electromagnetic discharge valve 13 is communicated with the lower end of the vibration box 9. The discharge port of the electromagnetic discharge valve 13 is communicated with a discharge hose 21 that penetrates out below the screening box 1.

[0030] After the ore dressing is completed, opening the electromagnetic discharge valve 13 is conducive to discharging the ore at the bottom of the vibration box 9 from the discharge hose 21. And opening each electromagnetic discharge valve 19 in sequence is conducive to discharging the ore on each screen mesh 18 from the corresponding discharge hose 20 in sequence.

[0031] All the technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiment is a preferred implementation scheme of the present invention. In addition, there are other implementation manners. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
