Description

Technical Field

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

[0002] Mining, as a core link in the acquisition of mineral resources, generates a large amount of dust during its operations (including blasting, excavation, crushing, and transportation). This dust mainly consists of rock fragments and mineral particles, with particle sizes ranging from a few micrometers to hundreds of micrometers. Among them, fine particulate matter such as PM10 and PM2.5 poses a particularly prominent hazard and has become a key issue restricting the green development of the mining industry and threatening operational safety and the ecological environment.

[0003] Currently, the dust suppression methods used in the mining industry for the transportation process are relatively simple, with spray dust suppression being the mainstream technology. Spray dust suppression involves spraying water mist onto the transported stone using high-pressure water guns or nozzles to capture dust particles. However, this method requires a large amount of water resources and cannot meet the needs for efficient, water-saving, and environmentally friendly dust suppression. Utility Model Content

[0004] The purpose of this invention is to provide a dust suppression device for mining and conveying processes, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for mining conveying, comprising a conveying frame with a stepped structure, the conveying frame including a front immersion section, a middle inclined draining section and a rear discharge section, and stepped guide grooves symmetrically provided on the side wall of the conveying frame;

[0006] The transmission frame is equipped with a transmission mechanism, which includes a servo motor installed on the side wall of the discharge section. The output end of the servo motor is connected to an active roller that is rotatably connected to the transmission frame. A driven roller is rotatably connected between the inner walls of the immersion section. A conveyor belt with a stepped structure is connected between the active roller and the driven roller, and the side end of the conveyor belt is correspondingly and movably arranged in the guide groove. Multiple baffles are fixedly connected to the surface of the conveyor belt at equal intervals, and several drainage holes are evenly provided on the baffles.

[0007] The immersion section is equipped with water that submerges the baffle plate.

[0008] Preferably, a feeding funnel is provided at the upper end of the immersion section.

[0009] Preferably, a drain valve is provided at the lower end of the immersion section.

[0010] Preferably, multiple transition rollers are provided between the conveyor belts, and the transition rollers rotate with the side wall of the transmission frame.

[0011] Preferably, the length of the baffle plate is equal to the width between the inner walls of the transfer frame.

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

[0013] 1. Significant dust suppression effect with comprehensive coverage: This utility model adopts a "water immersion dust suppression" mode. The immersion section is pre-filled with clean water to submerge the baffle plate. After the stone is fed through the feeding funnel, it is completely soaked. The dust is quickly moistened and agglomerated upon contact with water, which can thoroughly remove rock fragments, mineral particles and other dust adhering to the surface of the stone, significantly improving dust suppression efficiency.

[0014] 2. Water-saving and environmentally friendly, reducing resource consumption: This utility model has a high water resource utilization rate. It only needs to maintain a fixed water level in the immersion section and does not require continuous water supply. It only needs to replace the sewage periodically through the drain valve, which meets the requirements of water conservation and environmental protection. Attached Figure Description

[0019] Please see Figure 1-3 This utility model provides a technical solution: a dust suppression device for mining and conveying, including a conveyor frame 1 with a stepped structure. The conveyor frame 1 includes a front water immersion section 11, a middle inclined drain section 12 and a rear discharge section 13. The side wall of the conveyor frame 1 is symmetrically provided with stepped guide grooves 14.

[0020] The transmission frame 1 is equipped with a transmission mechanism 2. The transmission mechanism 2 includes a servo motor 21 installed on the side wall of the discharge section 13. The output end of the servo motor 21 is connected to a drive roller 22 that is rotatably connected to the transmission frame 1. A driven roller 23 is rotatably connected between the inner walls of the immersion section 11. A conveyor belt 24 with a stepped structure is connected between the drive roller 22 and the driven roller 23. The side end of the conveyor belt 24 is correspondingly and movably arranged in the guide groove 14. Multiple baffles 25 are fixedly connected to the surface of the conveyor belt 24 at equal intervals. Several drainage holes 251 are evenly provided on the baffles 25. The immersion section 11 is filled with water that submerges the baffles 25.

[0021] Furthermore, a feeding funnel 3 is provided at the upper end of the immersion section 11. The quarried stone enters the immersion section 11 through the feeding funnel 3, and then enters the space between the baffle plates 25. The water inside the immersion section 11 removes dust from the stone, thereby achieving dust reduction during stone transportation.

[0022] Furthermore, a drain valve 111 is provided at the lower end of the immersion section 11. The drain valve 111 facilitates the periodic cleaning of wastewater that absorbs dust from the stone, and then clean water is added from the discharge funnel 3.

[0023] Furthermore, multiple transition rollers 26 are provided between the conveyor belts 24, and the transition rollers 26 rotate with the side wall of the transmission frame 1. The transition rollers 26 provide support for the conveyor belts 24 to prevent them from sagging due to the weight of the stones; on the other hand, they reduce the friction of the conveyor belts 24 during operation, ensuring a smooth and stable transmission process.

[0024] Furthermore, the length of the baffle plate 25 is equal to the width between the inner walls of the conveyor frame 1. The baffle plate 25 is used to support the stones during conveying in the draining section 12 to prevent slippage; and the draining holes 251 provided on the baffle plate 25 are used to drain the water adhering to the stones.

[0025] Specifically, the workers first precisely feed the mined stone into the device through the feeding funnel 3 at the top of the soaking section 11. The feeding funnel 3 can prevent the stone from scattering when it is fed in, and ensure that the stone enters the soaking area in a concentrated manner. Since the soaking section 11 is pre-filled with clean water that can completely submerge the baffle plate 25, the stone will be fully soaked after falling in. The dust on the surface of the stone will be moistened and agglomerated after encountering water, thus achieving water soaking and dust reduction. The stone falls between the baffle plates 25 on the surface of the conveyor belt 24. The length of the baffle plate 25 is consistent with the width of the inner wall of the transmission frame 1, which can prevent the stone from sliding off the sides of the conveyor belt and ensure that the stone stays stably in the soaking area.

[0026] Then, the servo motor 21 installed on the side wall of the discharge section 13 is started. The servo motor 21 outputs power to drive the active roller 22 connected to it to rotate clockwise. When the active roller 22 rotates, it drives the conveyor belt 24 to run. At the same time, the driven roller 23 on the inner wall of the immersion section 11 rotates synchronously with the conveyor belt 24, forming a stable transmission structure. The side end of the conveyor belt 24 is embedded in the stepped guide groove 14 on the side wall of the transmission frame 1 to ensure that the conveyor belt runs along a fixed track and avoids deviation. The conveyor belt 24 drives the baffle plate 25 and the stone to the inclined drainage section 12 in the middle. Since the drainage section 12 has an inclined structure, the excess water attached to the surface of the stone will drip off through the evenly distributed drainage holes 251 on the baffle plate 25 under the action of gravity, realizing the separation of stone and water, and avoiding excessive water during subsequent discharge, which will affect the use.

[0027] Finally, after being drained, the stone continues to move along the conveyor belt 24 to the discharge section 13 at the end of the transmission frame 1. At this point, the stone has completed the dust suppression and draining treatment and is naturally discharged from the conveyor belt 24 to enter the subsequent processing or storage stage, completing the entire transmission and dust suppression process.
