Description

Technical Field

[0001] This utility model relates to the field of iron concentrate processing, and in particular to an auxiliary dust reduction device for iron concentrate processing. Background Technology

[0002] Iron concentrate is a material produced by crushing and beneficiating iron ore. In the production and processing of iron concentrate, the iron ore needs to be initially crushed. After crushing, it is generally transported by conveyor belt and water mist is used to combine with the dust particles to increase their weight, causing them to settle or be captured.

[0003] However, existing dust suppression equipment still has some problems in practical use. For example, many spray dust suppression devices are fixedly installed at specific locations and heights. The height and position of equipment on iron concentrate processing production lines, such as conveyor belts and chutes, may change due to process adjustments, equipment maintenance, site limitations, or the requirements of different production lines. Due to the vibration generated during conveying or processing, dust on the surface of iron ore will be scattered in the working environment, posing a threat to the health of workers. Existing fixed spray equipment cannot adapt to this change and cannot be adjusted up and down according to the actual height of material flow and the specific location of dust generation. This results in the spray position being too high, where the water mist cannot effectively cover the dust source, leading to poor dust suppression effect; or the spray position being too low, which may interfere with the normal flow of materials, limiting the applicable scope and dust suppression efficiency of the dust suppression equipment, and making it difficult to guarantee the accuracy of dust suppression operations. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary dust suppression device for iron concentrate processing. Through a positioning component, the dust suppression nozzle can rotate up and down as needed to achieve precise coverage of dust sources at different heights and improve the dust suppression effect.

The outer wall of the toothed plate is slidably connected to the inner wall of the fixed frame, and the first gear and the second gear are rotatably connected inside the fixed frame.

[0008] Furthermore, a dust-suppressing nozzle is fixedly mounted on the outer wall of the rotating ring. Compression springs are fixedly connected to both the upper and lower sides of the inner wall of the dust-suppressing nozzle. A horizontal plate is fixedly connected to the outer wall of the compression spring. A snap fastener is fixedly connected to the outer wall of the horizontal plate.

Detailed Implementation

[0017] 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.

[0018] Reference Figures 1-3This utility model provides an embodiment of an auxiliary dust suppression device for iron concentrate processing, comprising a base 1, a conveyor belt 4 fixedly connected to the top of the base 1, a first motor 3 fixedly connected to the right end of the conveyor belt 4, a fixed frame 2 fixedly connected to the top of the outer wall of the base 1, a second feed inlet 5 fixedly connected to the top of the fixed frame 2, the bottom end of the second feed inlet 5 corresponding to the top of the conveyor belt 4, connecting rods 11 rotatably connected to the left and right sides of the top of the fixed frame 2, rotating rings 10 fixedly connected to the outer walls of the two connecting rods 11, the outer walls of the rotating rings 10 rotatably connected to the inner wall of the base 1, a first gear 12 fixedly connected to the rear end of the outer wall of the connecting rods 11, a rotating assembly provided on the outer wall of the first gear 12, the first gear 12 being connected to another first gear 12 through the rotating assembly, the rotating assembly including a toothed plate 13 meshing with the outer wall of the first gear 12, the bottom end of the outer wall of the toothed plate 13 meshing with... A second gear 14 is connected to the base 1. A rotating rod 17 is fixedly connected to the inner wall of the second gear 14. A second motor 15 is fixedly connected to the rear end of the rotating rod 17. The second motor 15 is used to drive the second gear 14 to rotate. Another rotating rod 17 is rotatably connected to the right end of the inner wall of the base 1. The two rotating rods 17 are connected by a synchronous belt. The outer wall of the toothed plate 13 is slidably connected to the inner wall of the fixed frame 2. The first gear 12 and the second gear 14 are rotatably connected inside the fixed frame 2. A base column is fixedly connected to the bottom end of the base 1. A storage tank 7 is fixedly connected to the bottom end of the base column. The storage tank 7 is used to store water. A pressure pump 8 is fixedly connected to the top end of the storage tank 7. A hose 6 is fixedly connected to both the left and right sides of the top end of the pressure pump 8. The outer wall of the hose 6 is fixedly connected to the outer wall of the rotating ring 10. A first feed port 16 is fixedly connected to the rear side of the top end of the storage tank 7. The first feed port 16 is used to add water to the storage tank 7.

[0019] Specifically, the operator needs to add a measured amount of clean water to the storage tank 7 through the first feed inlet 16 reserved on the equipment. This step ensures that there is sufficient water for subsequent dust suppression. After the preparation is complete, the second motor 15 and the first motor 3 are turned on. The first motor 3 drives the conveyor belt 4 to start rotating smoothly. At this time, the processed iron concentrate can be added evenly and continuously to the rotating conveyor belt 4 through the second feed inlet 5 to start its transportation process. The iron concentrate forms a continuous material flow on the conveyor belt 4, providing a clear target for subsequent dust suppression. At the same time, the second motor 15 also starts working, driving the rotating rod 17 to rotate. Then, the rotating rod 17 is connected to another rotating rod 17 through a synchronous belt to ensure stable power transmission. The rotating rod 17 further drives the connected second gear 14 to rotate. Then, when the second gear 14 rotates, it drives the toothed plate 13 to move vertically up and down, causing the toothed plate 13 to drive the second gear 14 to rotate. A gear 12 rotates, driving the connecting rod 11 to rotate, causing the rotating ring 10 to rotate as well. As the rotating ring 10 continues to rotate, the dust suppression nozzle 9 swings up and down in the vertical plane. Simultaneously, the pressure pump 8 is activated, which draws water stored in the storage tank 7 through the hose 6 to the rotating ring 10 and then sprays it out as a fine water mist. Because the dust suppression nozzle 9 is continuously rotating up and down, this water mist can evenly cover the iron concentrate material flow transported on the conveyor belt 4. In areas where dust is easily stirred up, the dynamic and wide-angle spraying method is far more effective in capturing and suppressing dust than static spraying, achieving real-time and efficient water mist dust suppression treatment of iron concentrate during processing and transportation. By having two dust suppression nozzles 9 rotate up and down synchronously, it is ensured that dust within the entire width of the conveyor belt 4 can be effectively controlled.

[0020] Reference Figure 3 and Figure 4 The outer wall of the rotating ring 10 is fitted with a dust-suppressing nozzle 9. The upper and lower sides of the inner wall of the dust-suppressing nozzle 9 are fixedly connected with compression springs 19. The outer wall of the compression spring 19 is fixedly connected with a horizontal plate. The outer wall of the horizontal plate is fixedly connected with a buckle 20. The buckle 20 is used to snap into the rotating ring 10. The top of the outer wall of the horizontal plate is fixedly connected with a snap fastener 18. The outer wall of the snap fastener 18 is slidably connected to the inner wall of the dust-suppressing nozzle 9.

[0021] Specifically, pressing the buckle 18 by hand causes the horizontal plate to move downwards, compressing the internal compression spring 19. The compression spring 19 generates a reaction force after being compressed. At the same time, the movement of the horizontal plate forces the buckle 20 to disengage from the locking position of the rotating ring 10. Once the buckle 20 is disengaged from the rotating ring 10, the connection between the dust suppression nozzle 9 and the equipment is released. At this time, the operator can easily remove the old dust suppression nozzle 9 that needs maintenance or replacement from the rotating ring 10.

[0022] Working principle: Water is added to the storage tank 7 through the first feed inlet 16. Then, the second motor 15 and the first motor 3 are started, causing the first motor 3 to drive the conveyor belt 4 to rotate. Iron concentrate is then added and transported onto the conveyor belt 4 through the second feed inlet 5. The second motor 15 drives the rotating rod 17 to rotate, and the rotating rod 17 drives another rotating rod 17 to rotate via a synchronous belt. The rotating rod 17 drives the second gear 14 to rotate, and the second gear 14 drives the toothed plate 13 to move up and down. The toothed plate 13 moves up and down, causing the toothed plate 13 to drive the first gear 12 to rotate. The first gear 12 drives the rotating ring 10 on the connecting rod 11 to rotate, which in turn drives the dust suppression nozzle 9 to rotate. At the same time, the pressurizing pump 8 is started, which sends water from the storage tank 7 into the hose 6 through the buckle 18. After being filled, the water passes through the rotating ring 10 to the dust suppression nozzle 9 and is sprayed out to perform water mist dust suppression treatment on the processed iron concentrate powder. The dust suppression nozzles 9 on both sides rotate up and down continuously to cover the processed iron concentrate powder. When it is necessary to replace the dust suppression nozzle 9, press the buckle 18 so that the buckle 18 drives the horizontal plate to squeeze the pressure spring 19, and at the same time, the horizontal plate drives the buckle 20 to leave the rotating ring 10, and then the old dust suppression nozzle 9 can be maintained or replaced.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
