Description

Technical Field

[0001] This utility model relates to the field of iron ore mining technology, specifically to a dust suppression device for iron ore mining. Background Technology

[0002] Iron ore mining refers to the process of extracting and excavating iron ore from the surface or underground, and it is the first step in transforming iron ore into iron products. The iron ore mining process typically includes exploration, development, mining, ore beneficiation, and transportation. During iron ore mining, dust is easily generated by soil and rocks. For example, when loading ore into trucks, dust is easily stirred up due to vibration or handling. To ensure the health and safety of workers, dust suppression measures are necessary, and dust suppression devices are equipment used for dust control. Existing dust suppression devices typically consist of supports, pipes, and nozzles. When loading ore, the truck is located inside the supports, and water is sprayed onto the dust through the nozzles to achieve a dust suppression effect. However, the nozzles of existing dust suppression devices are usually fixed to the pipes, which limits their angle and thus their spraying range. This not only leads to poor dust suppression but also easily wastes water resources.

[0003] To address the aforementioned shortcomings, a dust suppression device for loading ore in iron ore mining can be referenced (Chinese patent application number CN202220252163.9, publication date 2022-06-21). During operation, the truck drives onto the load-bearing plate, which then lowers. The load-bearing plate, via a steel wire rope, drives a long pin to rotate inside the column. This long pin, through a push rod and crossbar, drives a connecting shaft to rotate inside the column. The connecting shaft then drives the spraying device to rotate synchronously, increasing the dust suppression range of the spraying device, saving water resources, and improving work efficiency. While existing technologies can increase the spraying range of the nozzles by driving them to rotate, the nozzles primarily rotate horizontally back and forth. This results in a dead angle between the nozzle and the rotating rod, making it easy for some dust to remain unsuppressed, often leading to poor results. Therefore, we propose that using a dust suppression device in iron ore mining can effectively solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a dust suppression device for iron ore mining, so as to solve the problem of the limited effectiveness of current dust suppression devices on the market as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for iron ore mining, comprising supports installed on both sides of a base, with a water storage tank at the top of each of the supports; a dust suppression mechanism is provided on the inner side of each support, the dust suppression mechanism including a connecting plate installed at the bottom of the water storage tank, and a rotating rod connected between the two supports via a bearing, with the left side of the rotating rod being through-connected to one of the supports, a torsion spring connecting the rotating rod and the support, a driven gear connected to the left side of the rotating rod, a motor installed on the outer side of one of the supports, and a half gear connected to the output end of the motor; symmetrically arranged filter screens are installed at the top of the base, and symmetrically arranged guide grooves are provided at the top of the base.

[0006] Furthermore, the half gear is located at the bottom end of the driven gear and is meshed with the driven gear. A water inlet pipe is connected to one side of the water storage tank, and a guide channel is located between the two filter screens.

[0007] Furthermore, a support block is installed at the top of the rotating rod, and a water spray head is connected to the outside of the support block via a bearing. The connecting plate extends to one side of the water spray head, and a magnetic block is installed on the right side of the connecting plate. A flexible hose is connected between the water spray head and the water storage tank.

[0008] Furthermore, a magnetic block is also installed on the left side of the spray head, and the two magnetic blocks are arranged opposite each other. There are a total of five spray heads.

[0009] Furthermore, the top of the base is provided with symmetrically arranged water collection tanks, and the filter screen is located at the top of the water collection tanks. The top of the base is provided with waste tanks, and there are four waste tanks in total, with each pair forming a group.

[0010] Furthermore, a cleaning mechanism is provided on the outer side of the bracket, and the cleaning mechanism includes a housing installed on the outer side of the bracket. A connecting block is slidably connected inside the housing, and the inner side of the connecting block is slidably connected to the bracket. A push rod is symmetrically arranged on the outer side of the rotating rod, and a cleaning brush is installed on the inner side of the bracket. The bottom end of the cleaning brush is in contact with the top end of the filter screen.

[0011] Furthermore, a push block is installed at the top of the cleaning brush, and the front end of the push block is in contact with the push rod. Both sides of the connecting block are connected to the outer shell with a return spring, and the push block is designed with a trapezoidal structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) A dust suppression mechanism is provided. The motor is started by a switch, which drives the half gear to rotate through the shaft at the output end of the motor. The half gear drives the driven gear to rotate, and drives the rotating rod to rotate together. The support block installed at the top of the rotating rod drives the water spray head connected to the support block through the bearing to rotate together. When the half gear tooth block separates from the driven gear, the rotating rod resets and rotates under the action of the torsion spring. Thus, the rotation of the half gear drives the water spray head to swing back and forth, thereby solving the problem of the limited effect of the dust suppression device.

[0014] (2) Furthermore, when the rotating rod drives the spray head to swing back and forth, the magnetic block on one side of the spray head will continuously approach the magnetic block on the side of the connecting plate. Since the two magnetic blocks are set opposite each other, they will generate a repulsive magnetic force when they approach each other. This repulsive magnetic force will drive the spray head to swing left and right, thereby achieving multi-directional dust suppression by swinging the spray head back and forth and left and right.

[0015] (3) A water collection tank and a filter screen are provided. When the water spray head sprays water to reduce dust, the excess water will fall to the top of the base by gravity and flow to the top of the filter screen through the guide channel. The water will then pass through the filter screen to filter out the mud and sand and flow into the interior of the water collection tank, thereby realizing the reuse of water resources and improving the environmental protection effect of the device.

[0016] (4) A cleaning mechanism is provided. When the rotating rod rotates back and forth, it drives the push rod sleeved on its outer side to swing back and forth. This pushes the push block and the cleaning brush installed at the bottom of the push block to move together. Since the push block is a trapezoidal structure, the push rod will separate from the push block when it reaches a certain height. This allows the cleaning brush to be reset under the action of the reset spring. The push rod swings back and forth to drive the cleaning brush to move back and forth, thereby cleaning the filter screen. Attached Figure Description

[0024] 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.

[0025] This utility model provides the following technical solution:

[0026] Example 1: To increase the dust suppression range of the device, please refer to the attached document. Figure 1-3 and attached Figure 6 A dust suppression device for iron ore mining includes supports 2 installed on both sides of a base 1, with a water tank 3 at the top of each support 2. A dust suppression mechanism is installed inside each support 2, including a connecting plate 10 installed at the bottom of the water tank 3. A rotating rod 7 is connected between the two supports 2 via a bearing, and the left side of the rotating rod 7 is through-connected to one of the supports 2. A torsion spring connects the rotating rod 7 to the support 2. A driven gear 6 is connected to the left side of the rotating rod 7. A motor 4 is installed on the outside of one of the supports 2, and a half-gear 5 is connected to the output end of the motor 4. Symmetrically arranged filter screens 13 are installed at the top of the base 1. The base 1 has symmetrical guide grooves at its top. Half gear 5 is located at the bottom of driven gear 6 and is meshed with driven gear 6. A water inlet pipe is connected to one side of the water tank 3. The guide groove is located between two filter screens 13. A support block 8 is installed at the top of the rotating rod 7. A water nozzle 9 is connected to the outside of the support block 8 through a bearing. A connecting plate 10 extends to one side of the water nozzle 9. A magnetic block 11 is installed on the right side of the connecting plate 10. A hose is connected between the water nozzle 9 and the water tank 3. A magnetic block 11 is also installed on the left side of the water nozzle 9. The two magnetic blocks 11 are arranged opposite each other. There are a total of five water nozzles 9.

[0027] The vehicle is parked on top of base 1, and ore is loaded onto the top of base 1. At this point, the switch is manually turned on, starting motor 4. The output shaft of motor 4 drives half-gear 5 to rotate, which in turn drives driven gear 6 through the meshing force of half-gear 5. This drives the rotating rod 7 connected to driven gear 6 to rotate, which in turn drives the support block 8 mounted on top of the rotating rod 7 to rotate the water spray head 9 connected to the support block 8 via a bearing. This causes the torsion spring to twist under the force of rotation. When the teeth of half-gear 5 separate from driven gear 6, the rotating rod 7 releases the spring... The water spray head 9 is reciprocated by a resetting swing under the force of the force, which in turn drives the water spray head 9 to swing back and forth through the rotation of the half gear 5. When the rotating rod 7 drives the water spray head 9 to swing back and forth, the magnetic block 11 on one side of the water spray head 9 will intermittently approach the magnetic block 11 on the side of the connecting plate 10. Since the two magnetic blocks 11 are set opposite each other, they will generate a repulsive magnetic force when they approach each other. This repulsive magnetic force will push the water spray head 9 to swing left and right. Thus, the water spray head 9 can achieve multi-directional dust suppression by swinging back and forth and left and right, which solves the problem of limited effectiveness of dust suppression devices.

[0028] Example 2: To achieve water resource reuse and cleaning of filter screen 13, please refer to the appendix. Figure 1 Appendix Figure 2 Appendix Figure 4 and attached Figure 5 A dust suppression device for iron ore mining is provided. A symmetrically arranged water collection tank 12 is provided at the top of the base 1, and a filter screen 13 is located at the top of the water collection tank 12. A waste trough 14 is provided at the top of the base 1, and there are four waste troughs 14 in total, with two in each group. A cleaning mechanism is provided on the outside of the support 2, and the cleaning mechanism includes a housing 15 installed on the outside of the support 2. A connecting block 16 is slidably connected inside the housing 15, and the inner side of the connecting block 16 is slidably connected to the support 2. A symmetrically arranged push rod 19 is sleeved on the outside of the rotating rod 7, and a cleaning brush 17 is installed on the inside of the support 2. The bottom end of the cleaning brush 17 is in contact with the top of the filter screen 13, and a push block 18 is installed on the top of the cleaning brush 17. The front end of the push block 18 is in contact with the push rod 19. A return spring 20 is connected between both sides of the connecting block 16 and the housing 15. The push block 18 is a trapezoidal structure.

[0029] When the water spray head 9 sprays water for dust suppression, excess water falls to the top of the base 1 by gravity and is guided to the top of the filter screen 13 through the guide channel. The water then passes through the filter screen 13 to filter out the mud and sand before flowing into the water collection tank 12. When the rotating rod 7 rotates back and forth, it drives the push rod 19, which is sleeved on its outside, to swing back and forth. This push rod 19 pushes the push block 18 and the cleaning brush 17 installed at the bottom of the push block 18 to move together, thereby stretching the return spring 20. Since the push block 18 has a trapezoidal structure, when the push rod 19 reaches a certain height, it will separate from the push block 18. This allows the cleaning brush 17 to return to its original position under the action of the return spring 20. The back and forth swing of the push rod 19 drives the cleaning brush 17 to move back and forth, thus scraping the mud and sand on the surface of the filter screen 13 into the waste tank 14. This achieves the cleaning of the filter screen 13 and the reuse of water resources. The waste tank 14 effectively prevents waste from polluting the ring.
