Technical Field
[0001] This utility model relates to the field of mine cooling and dust removal technology, and in particular to a cooling and dust removal device for underground mines. Background Technology
[0002] As the depth of underground metal mining increases, the temperature of the rock strata also rises, and safety issues caused by high ground temperatures gradually emerge, especially during the deep mining and development phase. When excavating single-ended tunnels, due to the lack of ventilation, workers not only have to endure the high temperatures and heat hazards of the working environment, but also face a large amount of dust generated during the excavation process. The harsh working environment not only affects the work efficiency of the construction workers, but also endangers their health.
[0003] Currently, equipment used for ventilation, dust removal, and cooling in mines is often equipped with casters on its chassis for easy movement. However, for single-face tunneling, the floor of the tunnel contains a large amount of waste rock, which can hinder the normal movement of the casters and thus affect the cooling and dust removal effect.
[0004] Therefore, it is of great importance to design equipment for cooling and dust removal in the development stage of underground mines, especially for single-ended roadways, to improve the working comfort and production efficiency of construction workers while protecting their health.
[0005] In view of this, it is necessary to design an improved cooling and dust removal device for underground mines to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a novel cooling and dust removal device for underground mines. An electrically driven tracked chassis is installed below the cooling and dust removal components, and the tracks are moved by electric drive wheels. Compared with traditional rollers, the electrically driven tracked chassis can move more easily and quietly on the gravel road. This device can not only effectively improve the ambient temperature of the working face, but also reduce dust concentration, improve work efficiency, and protect the health of workers.
[0007] To achieve the above objectives, this utility model provides a cooling and dust removal device for underground mines, comprising an electrically driven tracked chassis, a cooling component, and a dust removal component arranged sequentially from bottom to top; the cooling component includes a semiconductor cooling box and a water tank arranged sequentially along the forward direction of the electrically driven tracked chassis; the water tank is equipped with a water pump; the semiconductor cooling box is equipped with a semiconductor cooling chip closely attached to the side wall of the water tank and a heat sink connected to the semiconductor cooling chip; the dust removal component includes a mist sprayer rotatably mounted on the water tank, and the outlet end of the water pump, the outlet end of the water tank, the inlet end of the mist sprayer, and the spray nozzle of the mist sprayer are sequentially connected by pipes.
[0008] As a further improvement of this utility model, the electric drive tracked chassis includes a support plate and a plurality of electric drive wheels disposed on opposite sides of the support plate and a track wrapped around the electric drive wheels; the cooling component is disposed on the support plate.
[0009] As a further improvement of this utility model, the semiconductor refrigeration box is provided with air inlets on the side walls of the opposite sides perpendicular to the heat sink; the semiconductor refrigeration box is provided with an extraction fan on the side wall opposite to the heat sink for extracting hot air from the semiconductor refrigeration box.
[0010] As a further improvement of this utility model, the dust removal assembly also includes a support plate fixedly mounted on the water tank, and the end of the support plate away from the water tank is rotatably connected to the mist sprayer.
[0011] As a further improvement of this utility model, the dust removal assembly also includes an electric telescopic rod disposed between the water tank and the mist spraying fan, one end of the electric telescopic rod being hinged to the water tank and the other end being hinged to the mist spraying fan.

[0017] The beneficial effects of this utility model are:
[0018] (1) The cooling and dust removal device for underground mines provided by this utility model has an electric drive track chassis set below the cooling component and the dust removal component. The electric drive wheel drives the track to move. Compared with the traditional roller, the electric drive track chassis can move more easily and low on the gravel road, and is especially suitable for single-head excavation roadways to make up for blind spots in operation.
[0019] (2) The cooling and dust removal device for underground mines provided by this utility model utilizes a semiconductor refrigeration chip for cooling. Compared with traditional ice water refrigeration, it has lower transportation and storage costs, is more convenient to cool, and has a better cooling effect. In addition, the semiconductor refrigeration chip can be pre-cooled before cooling operations. When water is added to the water tank, cooling can be achieved more quickly, improving the cooling effect. Furthermore, the low-temperature water in the water tank is pumped into the mist sprayer and sprayed out from the spray nozzle of the mist sprayer in the form of water mist. The water mist captures suspended dust particles in the air, causing the dust particles to settle, achieving the dust removal effect. At the same time, the low-temperature water sprayed into the air further enhances the cooling effect, realizing the synergistic cooling of the low-temperature water in the water tank and the water mist sprayed by the mist sprayer.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.
[0028] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0029] Please see Figures 1 to 2 As shown, the cooling and dust removal device for underground mines provided by this utility model includes an electrically driven tracked chassis 1, a cooling component 2, and a dust removal component 3, arranged sequentially from bottom to top. The cooling component 2 includes components along the forward direction of the electrically driven tracked chassis 1 (…). Figure 1 (The direction indicated by the middle arrow is the forward direction) A semiconductor cooling box 22 and a water tank 21 are arranged sequentially; a water pump 23 is provided in the water tank 21; a semiconductor cooling chip 24 and a heat sink 25 connected to the semiconductor cooling chip 24 are provided in the semiconductor cooling box 22, which is in close contact with the side wall of the water tank 21. The dust removal assembly 3 includes a mist sprayer 31 rotatably mounted on the water tank 21. The water outlet of the water pump 23, the water outlet 26 of the water tank, the water inlet of the mist sprayer 31, and the spray nozzle 32 of the mist sprayer are connected sequentially by pipes. The water tank 21 is preferably a stainless steel water tank. With this setup, firstly, the thermoelectric cooler 24 continuously cools the water in the water tank 21, maintaining the water temperature in the tank 21 at a set low temperature to achieve a cooling effect. At the same time, the heat on the thermoelectric cooler 24 is transferred to the heat sink 25 for heat dissipation. Secondly, the low-temperature water in the water tank 21 is pumped into the mist sprayer 31 by the water pump 23 and sprayed out from the mist sprayer nozzle 32 in the form of water mist. The water mist captures suspended dust particles in the air, causing the dust particles to settle, achieving a dust removal effect. At the same time, the low-temperature water sprayed into the air further enhances the cooling effect.
[0030] like Figure 1 and Figure 2 As shown, the electric drive tracked chassis 1 includes a support plate (not shown) and several electric drive wheels 11 disposed on opposite sides of the support plate, and tracks 12 wrapped around the electric drive wheels 11. The support plate and the electric drive wheels 11 are connected by bearings. The cooling assembly 2 is disposed on the support plate. A battery pack providing power is installed in each electric drive wheel 11. The electric drive wheel 11 is electrically connected to the battery pack, which drives the electric drive wheel 11 to rotate, thereby driving the cooling assembly 2 and the dust removal assembly 3 forward. Additionally, the battery pack is electrically connected to a thermoelectric cooler 24 for cooling the thermoelectric cooler 24.
[0031] The thermoelectric cooler 22 has air inlets 27 on its opposite sidewalls (i.e., the sidewalls perpendicular to the heat sink 25), and an extraction fan 28 is provided on the sidewall of the thermoelectric cooler 22 opposite to the heat sink 25 to extract hot air from the thermoelectric cooler 22. With this configuration, when the battery pack is connected, the two end faces of the thermoelectric cooler 24 form a cooling surface and a heating surface. The cooling surface contacts the cooling water tank 21, cooling the water in the cooling water tank 21; the heating surface contacts the heat sink 25, dissipating heat through the heat sink 25. The extraction fan 28 continuously extracts hot air from the thermoelectric cooler 22 and replaces it with relatively low-temperature cold air, providing a certain amount of cooling to the heat sink 25. This ensures continuous cooling of the thermoelectric cooler 24 and provides a certain amount of cooling to the heat sink 25, preventing it from overheating and being damaged.
[0032] In some embodiments, a first dust filter is provided at the air inlet 27 of the semiconductor refrigeration box to filter dust and other impurities and prevent them from entering the semiconductor refrigeration box 22. The air inlet 27 of the semiconductor refrigeration box has a square structure.
[0033] The dust removal assembly 3 includes a mist sprayer 31 rotatably mounted on the water tank 21, and a support plate 33 mounted on the water tank 21. One end of the support plate 33 is fixed to the water tank 21, and the other end away from the water tank 21 is rotatably connected to the mist sprayer 31. The support plate 33 provides support for the mist sprayer 31.
[0034] To facilitate the adjustment of the height of the spray nozzle 32 of the mist sprayer, the dust removal assembly 3 also includes an electric telescopic rod 34 disposed between the water tank 21 and the mist sprayer 31. One end of the electric telescopic rod 34 is hinged to the water tank 21, and the other end is hinged to the mist sprayer 31. With this configuration, the height of the spray nozzle 32 of the mist sprayer can be adjusted through the combined action of the electric telescopic rod 34 and the support plate 33. Based on the floating position of the dust in the mine, low-temperature water is sprayed onto the dust to achieve dust removal. In addition, the electric telescopic rod 34 can also provide support for the mist sprayer 31, so that the mist sprayer 31 is stably set on the water tank 21 and prevents it from being damaged by large-scale shaking.
[0035] A ring of atomizing nozzles is provided on the spray nozzle 32 of the mist sprayer. Low-temperature water in the water tank 21 is pumped into the mist sprayer 31 by the water pump 23. The low-temperature water and the outside air drawn in by the air inlet 35 of the mist sprayer are carried out from the spray nozzle 32 of the mist sprayer under the high-speed airflow formed in the mist sprayer 31, forming a high-speed low-temperature atomized droplet group.
[0036] In some embodiments, a second dust filter is provided at the air inlet 35 of the mist sprayer to filter dust and other impurities and prevent dust and other impurities from entering the mist sprayer 31.
[0037] The water tank 21 is equipped with a level alarm 4 for detecting the water level in the water tank 21. When the water level in the water tank 21 is too low or too high, the level alarm 4 will sound an alarm to remind the staff to add or drain water.
[0038] The cooling and dust removal device for underground mines also includes a controller 5 mounted on a semiconductor cooling box 22 and a handheld wireless remote controller 6 wirelessly connected to the controller 5. The handheld wireless remote controller 6 transmits control signals to the controller 5 via wireless communication, thereby enabling the controller 5 to control the movement direction of the cooling and dust removal device for underground mines.
[0039] The working principle of this cooling and dust removal device for underground mines is as follows: First, the device is moved to the area requiring cooling and dust removal using a handheld wireless remote control 6. An appropriate amount of water (which can be cold water) is injected into the water tank 21 through the water inlet 29, and the water level in the tank 21 is detected by the level alarm 4 (or the device can be moved to the area requiring cooling and dust removal after water is added). The semiconductor cooling chip 24 continuously cools the water in the tank 21 using a battery pack installed in the electric drive wheel 11, maintaining the water temperature in the tank 21 at the set low temperature to achieve a cooling effect. Simultaneously, the semiconductor cooling chip 24... Heat is transferred to the heat sink 25, causing its temperature to rise. The exhaust fan 28 continuously extracts the hot air from the semiconductor cooling box 22 and replaces it with relatively cool air, providing a certain amount of cooling for the heat sink 25. Next, the low-temperature water in the water tank 21 is pumped into the mist sprayer 31 by the water pump 23. Simultaneously, the mist sprayer 31 pumps air in through the air inlet 35. The air and low-temperature water are sprayed out from the mist sprayer nozzle 32 as a water mist, capturing suspended dust particles in the air and causing them to settle, achieving a dust removal effect. The low-temperature water sprayed into the air further enhances the cooling effect. The mist sprayer 31 controls the vertical movement of the spray direction via the support plate 33 and the electric telescopic rod 34. Simultaneously, the movement of the electrically driven tracked chassis 1 moves the mist sprayer 31, thereby controlling the horizontal movement of the spray direction, achieving a comprehensive dust prevention and cooling effect.
[0040] In some embodiments, a flexible air duct can be connected to the air outlet of the exhaust fan 28, and the other end of the flexible air duct can be connected to the mine return air location, so that the hot air from the semiconductor cooling box 22 can be directly drawn to the mine return air location, avoiding the influence of hot air on the cooling effect.
[0041] In summary, the cooling and dust removal device for underground mines provided by this utility model features an electrically driven tracked chassis positioned below the cooling and dust removal components. The track is moved by electrically driven wheels, allowing for easier and lower movement on gravel roads compared to traditional rollers. This device not only effectively improves the ambient temperature at the work surface but also reduces dust concentration, increases work efficiency, and protects the health of workers. Furthermore, the device has a simple structure, is quick to install, and is easy to maintain.
[0042] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
