Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices, specifically to a dust removal device for mining equipment. Background Technology

[0002] While mining activities extract valuable resources, they also bring severe ecological challenges, leading not only to the continuous depletion of non-renewable resources but also causing widespread and irreversible damage to the natural environment. Large amounts of dust are generated during mining, stone processing, and crushing operations. This dust is characterized by its dispersed emission, wide coverage, and large generation volume, easily spreading outdoors with the wind and causing widespread air pollution, seriously affecting the surrounding ecological environment and residents' health. Therefore, designing specialized mining equipment with dust suppression devices for spray dust reduction is of paramount importance; this involves using water mist to adsorb dust particles, achieving effective suppression and settling.

[0003] However, existing dust removal devices used in mining equipment generally suffer from limited spray coverage and inconvenient direction adjustment. Most devices can only spray at a fixed angle, failing to achieve comprehensive, blind-spot-free dust coverage and easily creating dust blind spots. Furthermore, their ability to adjust spray particle size and diffusion angle is insufficient, making them unable to flexibly adjust according to changes in dust concentration, wind speed, and the working area, resulting in poor adaptability. Consequently, they cannot meet the demands of the complex and ever-changing mining environment for efficient and precise dust removal.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a dust removal device for mining equipment to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A dust removal device for mining equipment includes: a trolley; a water storage component disposed at the top of the trolley; a fan component disposed at the top of the water storage component; a rotating mechanism disposed on one side of the fan component for rotating and spraying the dust removal device; a spray component disposed at the top of the rotating mechanism and connected to the water storage component and the fan component; a spray adjustment component disposed at the end of the spray component away from the fan component for adjusting the size of the dust removal spray; and a control panel disposed on the outside of the water storage component.

[0007] Furthermore, to ensure an adequate water supply, the water filling process is automatically monitored through the linkage of the water level sensor and the control panel. This effectively prevents water pump damage due to water shortage or resource waste and safety hazards caused by overflow. The water storage components include: a water storage tank located on top of the trolley; a submersible pump located inside the water storage tank; an inlet pipe located on top of the water storage tank; a water level sensor located on the top of the inner wall of the water storage tank; and an outlet pipe located on top of the submersible pump and penetrating through the water storage tank.

[0008] Furthermore, in order to achieve accelerated water spraying and atomization, a stable and efficient airflow channel can be formed under the rotation of the fan. In conjunction with the first connecting hose, it ensures that the wind power is continuously and evenly delivered to the front end of the spray, providing strong power support for long-distance water mist spraying and significantly expanding the dust removal radius. The fan assembly includes: a protective shell, which is set at the top of the water storage assembly; a first motor, which is set inside the protective shell; a fan, which is set at one end of the first motor; a ventilation hole, which is opened on the side of the protective shell away from the rotating mechanism; and a first connecting hose, which is set on the other side of the protective shell and connected to the protective shell.

[0009] Furthermore, to achieve spray angle adjustment, the spray nozzle can be smoothly and precisely adjusted up and down through the cooperation of the worm gear and worm wheel transmission. The rotating protective frame driven by the third motor achieves horizontal rotation control, thereby achieving all-round spray coverage, effectively avoiding dust blind spots, and improving the overall cleanliness of the working surface. The rotating mechanism includes a second motor located on one side of the fan assembly, with a worm gear at the output end of the second motor. A worm wheel is meshed at the top of the worm gear, and the rotating protective frame is connected to the outside of the worm wheel. The third motor is connected to the end of the rotating protective frame away from the second motor, and support rods connected to the worm wheel are provided on both sides of the rotating protective frame. The rotating protective frame and the worm wheel are connected by bearings.

[0010] Furthermore, to ensure consistent spray density, the water flow is evenly distributed within the spray cylinder through the cross-shaped water pipe and nozzle distribution design, ensuring consistent spray density and avoiding excessively strong or weak local sprays. Combined with wind assistance, a fine and uniform water mist cloud is formed, greatly enhancing the ability to capture fine dust particles and improving dust suppression efficiency. The spray assembly includes a spray cylinder located at the top of the rotating mechanism. Inside the spray cylinder is a cross-shaped water pipe. Several nozzles are located on the side of the cross-shaped water pipe away from the fan assembly. A water delivery pipe that penetrates the spray cylinder is located in the middle of the other side of the cross-shaped water pipe, and a second connecting hose that connects to the water storage assembly is located on the side of the water delivery pipe closest to the fan assembly.

[0011] Furthermore, in order to adjust the atomization size of the spray, the size of the annular gap at the spray outlet can be flexibly controlled by adjusting the relative positions of the first and second spray baffles, thereby precisely adjusting the atomized particle size of the spray to meet the personalized needs of different dust concentrations, wind speeds, and work area sizes. The spray adjustment component includes a first spray baffle located at one end of the spray component, and the first spray baffle is connected to the spray component by a thread. Several limiting grooves are provided on the inner wall of the side of the first spray baffle away from the spray component. A second spray baffle is provided inside the side of the first spray baffle away from the spray component. Limiting frames are symmetrically arranged on the outer side of the second spray baffle. A spring is provided inside the limiting frame. A limiting block is provided inside the limiting groove at the end of the spring away from the second spray baffle. A pressing handle that cooperates with the limiting frame is provided on the outer side of the limiting block near the spring. Spray holes are provided on one side of both the first and second spray baffles.

[0012] The beneficial effects of this utility model are as follows: 1. This invention, through the coordinated arrangement of a trolley, water storage component, fan component, rotating mechanism, spray component, spray adjustment component, and control panel, not only enables dust removal during mining operations but also allows for precise adjustment of the spray diffusion angle to achieve all-around spray coverage, effectively avoiding dust blind spots and improving the overall cleanliness of the work surface. Furthermore, by flexibly controlling the size of the spray outlet, the atomized particle size of the spray can be precisely adjusted to meet the personalized needs of different dust concentrations, wind speeds, and work area sizes.

[0013] 2. Through the rotating mechanism, the spray nozzle can be smoothly and accurately adjusted up and down under the action of worm gear and worm wheel transmission. The rotating protective frame driven by the third motor realizes the horizontal rotation control, thereby achieving all-round spray coverage, effectively avoiding dust blind spots and improving the overall cleanliness of the working surface.

[0014] 3. The present invention, through the spray adjustment component, can flexibly control the size of the annular gap at the spray outlet by adjusting the relative position of the first spray baffle and the second spray baffle, thereby precisely adjusting the atomized particle size of the spray to meet the personalized needs of different dust concentrations, wind speeds, environments and work area sizes.

[0025] In one embodiment, the spray regulating assembly 6 includes a first spray baffle 601 disposed at one end of the spray assembly 5, and the first spray baffle 601 is threadedly connected to the spray assembly 5; a plurality of limiting grooves 602 are formed on the inner wall of the side of the first spray baffle 601 away from the spray assembly 5; a second spray baffle 603 is disposed inside the side of the first spray baffle 601 away from the spray assembly 5, and limiting frames 604 are symmetrically disposed on the outer side of the second spray baffle 603; a spring 605 is disposed inside the limiting frame 604, and the spring 605 is located away from the first spray assembly 5.

Spray holes are provided on one side of both the first spray baffle 601 and the second spray baffle 603. Under the adjustment of the relative position of the first spray baffle 601 and the second spray baffle 603, the size of the annular gap of the spray outlet can be flexibly controlled, thereby precisely adjusting the atomized particle size of the spray to meet the personalized needs of different dust concentrations, wind speed environments and work area sizes.

[0026] In addition, it should be noted that the control panel 7 consists of a human-machine interface (HMI) and a programmable logic controller (PLC), and the control panel 7 is electrically connected to the water storage component 2, the fan component 3, and the rotating mechanism 4; this control panel 7 is existing technology and will not be elaborated on further here.

[0027] Furthermore, it should be noted that the aforementioned water level sensor 204 is a radar-based liquid level sensor. This sensor monitors the water level to ensure timely replenishment of the water tank 201. The sensor utilizes radio wave transmission and reception to accurately measure the water level, providing stable and reliable results even in harsh environments. Specifically, the water level sensor monitors the water level in the water tank 201 and transmits the monitored signal to the control panel 7. This water level sensor 204 is existing technology and will not be elaborated upon further here.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In practical application, the device is first moved to the location requiring dust removal using a trolley 1. Water is then introduced into the water storage tank 201 via the inlet pipe 203. Simultaneously, the water level sensor 204 detects the water level signal in the tank 201 and transmits it to the control panel 7. The control panel 7 monitors the water level information. When the water level signal reaches the preset maximum water level, water supply to the tank 201 stops. Then, the control panel 7 controls the activation of the submersible pump 202 and the first motor 302. Under the pumping action of the submersible pump 202, the water in the tank 201 flows through the outlet pipe 205, the second connecting hose 505, and the delivery pipe 500. 4. Under the connection of the cross-shaped water pipe 502, water is delivered to the nozzle 503 for spraying. Simultaneously, the rotation of the first motor 302 causes the fan 303 to rotate, allowing air entering from the ventilation hole 304 to be output into the first connecting hose 305 and then delivered into the spray cylinder 501. This allows the air output from the first connecting hose 305 to accelerate and atomize the water sprayed from the nozzle 503, thus accelerating the atomized water mist to a distant dusty area, significantly improving the spray coverage and dust removal efficiency. To adjust the spray angle of the dust removal device, the second motor 40 is activated via the control panel 7. 1. Under the rotation of the second motor 401, the worm gear 402 rotates, which in turn drives the worm wheel 403 to rotate, thereby causing the spray cylinder 501 connected to the support rod 406 to move in an arc shape. This allows adjustment of the spray height produced by the spray cylinder 501. When the second motor 401 is stopped, the third motor 405 is started via the control panel 7. Under the rotation of the third motor 405, the rotating protective frame 404 rotates, thereby adjusting the left-right direction of the spray produced by the spray cylinder 501. When the spray size needs to be adjusted, the pressing handle 607 can be pressed closer to the end near the spring 605. The elasticity of the spring 605... Under this action, the limiting block 606 is no longer stuck in the limiting groove 602, allowing the second spray baffle 603 to be removed. After rotating and adjusting it by a certain angle, the second spray baffle 603 can be reinstalled. Releasing the pressing handle 607 and moving the second spray baffle 603 will allow it to re-engage in the first spray baffle 601, thus inserting the limiting block 606 into the new limiting groove 602. This causes the spray holes of the first spray baffle 601 and the second spray baffle 603 to interlock, adjusting the amount of obstruction the second spray baffle 603 has on the spray holes of the first spray baffle 601. The size of this annular gap determines the spray diffusion angle and atomization intensity, thus adapting to dust removal needs under different working conditions. This mobile deployment, combined with centralized control of the control panel 7, enables efficient, flexible, and intelligent dust control at the mining site.

[0030] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the trolley 1, water storage component 2, fan component 3, rotating mechanism 4, spray component 5, spray adjustment component 6, and control panel 7, not only can dust removal be achieved during the mining process, but the spray diffusion angle can also be precisely adjusted to achieve all-round spray coverage, effectively avoiding dust blind spots and improving the overall cleanliness of the working face; furthermore, by flexibly controlling the size of the spray outlet, the atomized particle size of the spray can be precisely adjusted to meet the personalized needs of different dust concentrations, wind speeds, and working area sizes; through the rotating mechanism 4, the worm gear can... The combined action of 402 and worm gear 403 enables the spray nozzle 501 to achieve stable and precise up-and-down pitch adjustment, while the rotating protective frame 404 driven by the third motor 405 achieves horizontal rotation control, thereby achieving all-round spray coverage, effectively avoiding dust blind spots, and improving the overall cleanliness of the working surface. Through the spray adjustment component 6, the size of the annular gap at the spray outlet can be flexibly controlled by adjusting the relative position of the first spray baffle 601 and the second spray baffle 603, thereby precisely adjusting the atomized particle size of the spray to meet the personalized needs of different dust concentrations, wind speeds, and working area sizes.
