Description

Technical Field

[0001] This utility model belongs to the field of coal mining technology, and in particular relates to a cooling and dust removal device for coal mining faces. Background Technology

[0002] During long-term continuous operation, coal mining faces often generate a large amount of dust due to factors such as the operation of mining equipment, coal and rock fracturing, and dense personnel operations, accompanied by a significant increase in ambient temperature. Dust suspended in the air not only affects the visibility and respiratory health of workers, but also easily accumulates on equipment surfaces and ventilation systems, increasing the risk of equipment failure. High-temperature environments reduce the working comfort of workers and adversely affect the stable operation of electrical equipment and mechanical components. Therefore, effective cooling and dust removal at mining faces is an important technical issue in coal mine safety production.

[0003] However, some problems still exist in the above solutions: Existing coal mine working faces often use methods such as spraying dust suppression or ventilation and cooling to improve the working environment. However, most of these devices have only one function. Spraying devices usually only play a role in dust suppression and have limited cooling effect. Ventilation or heat dissipation equipment is often only used for air circulation and is difficult to take into account dust control. In actual use, the spraying direction is mostly fixed and it is difficult to adjust it flexibly according to the spatial changes and dust distribution of the working face. This can easily lead to poor local cooling or dust removal effect, which affects the overall control effect. In addition, the dust concentration in the coal mine working environment is high. During long-term operation, coal dust in the air can easily enter the fan or adhere to the air intake, causing air duct blockage, reduced air volume, or even equipment damage. Frequent manual cleaning is usually required, which not only increases maintenance costs but also poses certain safety hazards. Furthermore, some devices lack effective dust prevention and self-cleaning structures, making it difficult to meet the working conditions of high dust and long-term operation in underground coal mines. Meanwhile, existing cooling or dust removal equipment is not adaptable to different operating stages. When the mining face is in a high temperature and high dust condition, cooling and spraying treatment need to be strengthened. When the temperature is relatively stable but dust still exists, continuous dust removal treatment is still required. Existing equipment often requires switching different equipment or adjusting complex operating procedures, which affects the continuity of operation and the efficiency of on-site management.

The adjustment mechanism includes a first adjustment component, a second adjustment component, a third adjustment component, a first electric push rod, a second electric push rod, a cooling fan, and a temperature control switch. The first electric push rod is rotatably connected to the inner side of the first adjustment component, and the third adjustment component is rotatably connected to one end of the first electric push rod. The second electric push rod is rotatably connected to the inner side of the third adjustment component, and the second adjustment component is rotatably connected to one end of the second electric push rod. The cooling fan is electrically connected to the temperature control switch. The cooling mechanism includes an atomizing nozzle, a transmission box, and a connecting pipe. The atomizing nozzle is fixedly connected to the bottom of the transmission box, and the connecting pipe is fixedly connected to the top of the transmission box.

[0006] Preferably, a connector is provided on the outside of the cooling and dust removal device body, the cooling fan is connected to the inside of the connector, and the temperature control switch is fixedly connected to the outside of the cooling and dust removal device body.

[0007] Preferably, the bottom end of the first adjusting member is fixedly connected to the top end of the connector, and the bottom ends of the second and third adjusting members are both fixedly connected to the top end of the cooling and dust removal device body.

[0008] Preferably, a dustproof mesh is engaged with the outer side of the connector, and a connecting rod is fixedly connected to the central shaft of the cooling fan, with one end of the connecting rod passing through the dustproof mesh.

[0009] Preferably, a support rod is fixedly connected to the top end of the connecting rod, an elastic fastener is fixedly connected to the inner side of the support rod, and a cleaning wiper is fixedly connected to the inner side of the elastic fastener.

[0010] Preferably, the inner side of the cleaning wiper is attached to the outer side of the dustproof net.

[0011] Preferably, the transmission box is fixedly connected to the inner wall of the cooling and dust removal device body, the top end of the connecting pipe penetrates the cooling and dust removal device body, and a transmission pump is fixedly connected to one side of the top end of the cooling and dust removal device body.

[0012] Preferably, the outlet end of the transfer pump is fixedly connected to one end of the connecting pipe, and the outlet end of the transfer pump is fixedly connected to the transfer pipe.

[0013] Compared with related technologies, the cooling and dust removal device for coal mine working faces provided by this utility model has the following beneficial effects: 1. The cooling and dust removal device for the coal mine working face has an adjustment mechanism on one side of the device body and a cooling mechanism inside. This allows the device to achieve targeted cooling and dust removal according to environmental changes at the working face during actual use. The first, second, and third adjustment components in the adjustment mechanism, driven by the first and second electric push rods, can adjust the spray direction of the atomizing nozzles at multiple angles, making the cooling mechanism cover a wider range. This avoids the problem that traditional fixed spray devices can only be effective in localized areas, thereby improving the uniformity and effectiveness of cooling and dust removal. It is particularly suitable for the working environment of coal mine working faces with large spaces and uneven dust distribution, which helps to improve the overall air quality of the working area and reduce the adverse effects of high temperatures on equipment and personnel.

[0014] 2. By installing a connector on the outside of the cooling and dust removal device and mounting the cooling fan inside the connector, along with the control of a temperature control switch, the cooling fan can operate in both forward and reverse blowing modes. When cooling is needed, the reverse blowing airflow, in conjunction with the cooling mechanism, allows the water mist sprayed from the atomizing nozzle to be fully diffused under the action of the airflow, improving cooling efficiency. When enhanced cooling is not needed, the forward blowing airflow draws in dust-laden air, and the atomizing nozzle effectively removes dust. This allows the same cooling fan to perform both cooling and dust removal functions under different operating conditions, reducing structural redundancy and improving overall integration. Furthermore, the temperature control switch enables automatic adjustment, reducing the frequency of manual intervention and improving the safety and continuity of coal mining operations.

[0015] 3. This device uses a dustproof net on the outside of the connector and the central shaft of the cooling fan to drive the connecting rod, support rod, and elastic fixing parts to move. This allows the cleaning wiping plate to continuously adhere to the outside of the dustproof net during device operation, automatically scraping away the attached coal dust. This prevents the dustproof net from becoming clogged due to long-term dust accumulation, ensuring stable ventilation for the cooling fan in both forward and reverse blowing modes. This extends the service life of the cooling fan and reduces maintenance frequency. At the same time, it prevents coal dust from entering the cooling fan and causing wear or malfunction. This effectively improves the operational reliability of the cooling and dust removal device in high-dust environments in coal mines and is suitable for long-term continuous operation.

[0016] 4. By installing a transmission box inside the cooling and dust removal device, and supplying water stably to the atomizing nozzles via a transmission pump, transmission pipe, and connecting pipe, the atomizing nozzles can form a fine and uniform water mist. Under the guidance of the cooling fan airflow and the regulating mechanism, the water mist fully contacts the coal dust in the air, causing the coal dust to settle rapidly due to adsorption of the water mist. This significantly reduces the dust concentration in the air at the mining face. At the same time, the water mist absorbs heat from the air during evaporation, achieving continuous cooling of the working environment. This structure allows the cooling and dust removal processes to cooperate and proceed synchronously, avoiding the problem of limited effectiveness of single-function devices and improving the overall effect of environmental management at the coal mine mining face.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] Example 1 A preferred embodiment of the cooling and dust removal device for a coal mine working face provided by this utility model is, for example... Figures 1 to 5 As shown: A cooling and dust removal device for a coal mine working face includes: a cooling and dust removal device body 2, an adjustment mechanism 3 on one side of the cooling and dust removal device body 2, and a cooling mechanism 4 inside the cooling and dust removal device body 2. The adjustment mechanism 3 includes a first adjustment component 302, a second adjustment component 305, a third adjustment component 306, a first electric push rod 303, a second electric push rod 304, a cooling fan 308, and a temperature control switch 307. The first electric push rod 303 is rotatably connected to the inner side of the first adjustment component 302. The third adjustment component 306 is rotatably connected to one end of the first electric push rod 303. The second electric push rod 304 is rotatably connected to the inner side of the third adjustment component 306. The second adjustment component 305 is rotatably connected to one end of the second electric push rod 304. The cooling fan 308 is electrically connected to the temperature control switch 307. The cooling mechanism 4 includes an atomizing nozzle 404, a transmission box 402, and a connecting pipe 401. The atomizing nozzle 404 is fixedly connected to the bottom end of the transmission box 402, and the connecting pipe 401 is fixedly connected to the top end of the transmission box 402.

[0022] In this embodiment, the cooling and dust removal device of the coal mine working face uses the cooling and dust removal device body 2 as the supporting foundation during operation. The working direction of the cooling mechanism 4 is adjusted by the adjustment mechanism 3 set on one side. After the device is started, the temperature control switch 307 monitors the ambient temperature and controls the operation of the cooling fan 308. Under the combined drive of the first electric push rod 303 and the second electric push rod 304, the adjustment mechanism 3 drives the first adjustment component 302, the second adjustment component 305 and the third adjustment component 306 to change angles, so that the cooling mechanism 4 can perform targeted spraying treatment on the working face. The water mist sprayed by the atomizing nozzle 404 diffuses to the working area under the action of airflow, thereby realizing the synergistic effect of cooling and dust removal.

[0023] In a further preferred embodiment of the present invention, a connector 1 is provided on the outside of the cooling and dust removal device body 2, a cooling fan 308 is connected to the inside of the connector 1, and a temperature control switch 307 is fixedly connected to the outside of the cooling and dust removal device body 2.

[0024] In this embodiment, by setting a connector 1 on the outside of the cooling and dust removal device body 2 and installing a cooling fan 308 on the inside of the connector 1, the cooling fan 308 forms a stable airflow under the control of the temperature control switch 307. During operation, the cooling fan 308 removes heat from the device through airflow exchange between the connector 1 and the cooling and dust removal device body 2. At the same time, the temperature control switch 307 automatically controls the start and stop of the cooling fan 308 according to changes in ambient temperature, so that the device can maintain a reasonable operating temperature under different working conditions, and avoid affecting the normal operation of the cooling mechanism 4 and the regulating mechanism 3 due to excessive temperature.

[0025] In a further preferred embodiment of the present invention, the bottom end of the first adjusting member 302 is fixedly connected to the top end of the connector 1, and the bottom ends of the second adjusting member 305 and the third adjusting member 306 are both fixedly connected to the top end of the cooling and dust removal device body 2.

[0026] In this embodiment, the first adjusting member 302 is fixed to the top of the connector 1 as the supporting base of the adjusting mechanism 3. The second adjusting member 305 and the third adjusting member 306 are fixed to the top of the cooling and dust removal device body 2 to form a stable installation structure. During the extension and retraction of the first electric push rod 303 and the second electric push rod 304, each adjusting member generates a linkage deflection under the rotational connection relationship, thereby causing the working direction of the cooling mechanism 4 to change, so that the spraying area of ​​the atomizing nozzle 404 can be adjusted according to the spatial distribution of the mining face, thereby improving the coverage effect of the cooling and dust removal range.

[0027] In a further preferred embodiment of the present invention, a dustproof mesh 301 is snapped onto the outer side of the connector 1, and a connecting rod 309 is fixedly connected to the central shaft of the cooling fan 308, with one end of the connecting rod 309 passing through the dustproof mesh 301.

[0028] In this embodiment, the dustproof net 301 provided on the outside of the connector 1 filters the incoming and outgoing airflow during the operation of the device, preventing coal dust from directly entering the interior of the cooling fan 308. When the cooling fan 308 rotates, its central shaft drives the connecting rod 309 to rotate synchronously. The connecting rod 309 passes through the dustproof net 301 and generates vibration during rotation, causing the coal dust attached to the surface of the dustproof net 301 to be disturbed and loosened and fall off, thereby ensuring that the dustproof net 301 maintains good ventilation performance for a long time and maintains the normal operation of the cooling fan 308.

[0029] In a further preferred embodiment of the present invention, a support rod 310 is fixedly connected to the top end of the connecting rod 309, an elastic fixing member 311 is fixedly connected to the inner side of the support rod 310, and a cleaning wipe plate 312 is fixedly connected to the inner side of the elastic fixing member 311.

[0030] In this embodiment, during the operation of the cooling fan 308, the connecting rod 309 drives the support rod 310 to move synchronously. The elastic fixing member 311 on the inner side of the support rod 310 undergoes elastic deformation under the action of centrifugal force, thereby driving the cleaning wiping plate 312 to reciprocate. During the movement, the cleaning wiping plate 312 scrapes off the coal dust attached to the surface of the dustproof net 301, so that the dustproof net 301 can be cleaned while the device is in operation, avoiding dust accumulation that affects airflow and improving the device's adaptability in high dust environments.

[0031] In a further preferred embodiment of this utility model, the inner side of the cleaning wiper 312 is attached to the outer side of the dustproof net 301.

[0032] In this embodiment, the inner side of the cleaning wiper 312 is always in contact with the outer surface of the dustproof net 301. Driven by the support rod 310 and the elastic fixing member 311, it rotates with the cooling fan 308 and performs periodic friction, so that the dust on the surface of the dustproof net 301 is continuously removed and falls off outward. Thus, the dustproof net 301 is automatically cleaned without affecting the operation of the cooling fan 308, reducing the frequency of manual maintenance and ensuring that the cooling fan 308 has a stable air intake and exhaust effect in both forward and reverse blowing states.

[0033] Example 2 Based on Embodiment 1, a preferred embodiment of the cooling and dust removal device for a coal mine working face provided by this utility model is as follows: Figures 1 to 5 As shown: the transmission box 402 is fixedly connected to the inner wall of the cooling and dust removal device body 2, the top end of the connecting pipe 401 penetrates the cooling and dust removal device body 2, and the transmission pump 403 is fixedly connected to one side of the top end of the cooling and dust removal device body 2.

[0034] In this embodiment, the transmission box 402 is fixed to the inner wall of the cooling and dust removal device body 2 to form a stable water supply structure. The connecting pipe 401 passes through the cooling and dust removal device body 2 and is connected to the transmission pump 403. When the device is running, the transmission pump 403 starts to deliver water to the connecting pipe 401. After the water flows into the transmission box 402, it is evenly distributed to the atomizing nozzle 404, so that the atomizing nozzle 404 can continuously and stably generate water mist, thereby providing a reliable working foundation for the cooling mechanism 4.

[0035] In a further preferred embodiment of the present invention, the outlet end of the transfer pump 403 is fixedly connected to one end of the connecting pipe 401, and the outlet end of the transfer pump 403 is fixedly connected to the transfer pipe 405.

[0036] In this embodiment, the outlet of the transfer pump 403 is fixedly connected to the connecting pipe 401 through the transfer pipe 405. During operation, the transfer pump 403 delivers water to the connecting pipe 401 through the transfer pipe 405 to form a continuous water flow. Under pressure, the water flow enters the transfer box 402 and is atomized and sprayed out by the atomizing nozzle 404, so that the water mist can be diffused to the mining face area under the guidance of the regulating mechanism 3 and the airflow of the cooling fan 308, thereby achieving the humidification and settling of dust in the air and assisting in the environmental cooling treatment.

[0037] In summary, during actual operation, the cooling and dust removal device at the coal mine working face uses the device body 2 as the overall installation and support foundation. Through the coordinated operation of the adjustment mechanism 3 and the cooling mechanism 4, the device achieves synchronous control and treatment of the high-temperature environment and dust at the working face. After the equipment is started, the temperature control switch 307 monitors the ambient temperature of the working face in real time and controls the operation of the cooling fan 308 based on the detection results. The cooling fan 308 is fixed to the outside of the cooling and dust removal device body 2 via connector 1. During operation, it can form a directional airflow that blows forward or backward according to the usage requirements to adapt to the cooling and dust removal needs under different working conditions. At the same time, the dustproof net 301 connected to the outside of connector 1 can filter the incoming and outgoing airflow to prevent coal dust particles from entering the cooling fan 308 and causing wear or jamming. When the temperature of the mining face is high and enhanced cooling is required, the cooling fan 308 is in a back-blowing state under the control of the temperature control switch 307. The back-blowing airflow enters the body 2 of the cooling and dust removal device through the connector 1 and flows along the direction of the cooling mechanism 4, so that the water mist sprayed by the atomizing nozzle 404 is fully diffused into the space of the mining face under the action of the airflow. During the diffusion process, the water mist absorbs the heat in the high-temperature air to achieve rapid cooling, and at the same time, it comes into full contact with the suspended coal dust particles in the air, causing the coal dust to become heavier and settle due to the attachment of water mist, thereby achieving the synergistic treatment of cooling and dust removal. At the same time, the back-blowing airflow accelerates the exchange of air between the inside and outside of the device during the flow process, improves the overall heat dissipation efficiency, and avoids the continuous rise of the internal temperature of the device body, which affects the stability of operation. During the operation of the cooling fan 308, its central shaft drives the fixed connecting rod 309 to rotate synchronously. One end of the connecting rod 309 passes through the dustproof net 301 and is connected to the support rod 310. The elastic fixing member 311 set on the inner side of the support rod 310 undergoes periodic deformation under the action of centrifugal force generated by the fan rotation, thereby driving the cleaning wipe plate 312 to reciprocate along the outer surface of the dustproof net 301, so that the dust attached to the dustproof net 301 is continuously scraped off and shaken off, avoiding the dustproof net 301 from affecting the ventilation effect in the forward or reverse blowing state due to long-term dust accumulation, thereby ensuring smooth airflow and stable operation of the cooling fan 308. When the temperature of the mining face is within the normal range and spray cooling is not required, the cooling fan 308 switches to the forward blowing state. The forward blowing airflow enters the cooling and dust removal device body 2 from the outside through the dustproof net 301. During this process, the cooling fan 308 draws in the surrounding dusty air, causing the coal dust in the air to enter the device with the airflow. When the airflow passes through the area of ​​the cooling mechanism 4, the fine water mist sprayed by the atomizing nozzle 404 wets and captures the drawn-in coal dust, causing the coal dust to condense and settle under the action of the water mist. Thus, the dust removal process is completed without forced cooling. At the same time, the forward blowing airflow continuously removes the heat accumulated inside the device, ensuring the operational stability of the cooling and dust removal device body 2. In both of the above operating states, the adjustment mechanism 3 plays the role of dynamically adjusting the airflow direction and spray area. The first adjustment component 302 is fixedly connected to the top of the connector 1 through its bottom end, providing an installation support point for the adjustment mechanism 3. The first electric push rod 303 and the second electric push rod 304 extend and retract alternately or synchronously under the control of the set program, driving the second adjustment component 305 and the third adjustment component 306 to change the angle, thereby realizing multi-angle adjustment of the spraying direction of the atomizing nozzle 404, so that the cooling or dust removal range covers the entire mining operation area, avoiding the problem of insufficient local treatment. By switching between forward and reverse blowing states of the cooling fan 308 and coordinating with the cooling mechanism 4 and the regulating mechanism 3, this cooling and dust removal device can flexibly select the cooling or dust removal operation mode according to the actual working conditions of the coal mine working face. While effectively reducing the temperature of the working environment, it continuously controls the dust content in the air, improves the safety of mining operations and the comfort of workers. The overall structure is stable and reliable in operation and is suitable for long-term continuous use in underground coal mines.
