Description

Technical Field

[0001] This application belongs to the field of mining equipment, and specifically relates to a mine ventilation and heat exhaust system. Background Technology

[0002] Deep mines are typically hot and humid environments, making it difficult for workers to maintain long-term operations. Heat extraction systems are needed to remove the heat, but traditional exhaust fans are ineffective at achieving this.

[0003] Due to the considerable depth and space of mines, existing ventilation systems mostly consist of high-powered fans connected to exhaust ducts. While these systems can extract hot and humid air, mines are often located in open areas, and to avoid the influence of strong winds, the fans are typically located underground. This not only results in significant noise but also greatly impacts the lifespan of the fans due to the hot and humid air. Furthermore, because of the considerable depth of mines, extracting air only from the bottom is insufficient for complete air exchange. Adding vents to the exhaust ducts would reduce the pressure inside the ducts, affecting the ventilation effect at the bottom.

[0004] Therefore, a new type of mine ventilation and heat dissipation system is needed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of the prior art, this application provides a mine ventilation and heat dissipation system that can adapt to windy environments and improve the service life of exhaust fans and heat dissipation effect.

[0006] The technical effect to be achieved in this application is accomplished through the following solution:

[0007] According to a first aspect of this application, a mine ventilation and heat dissipation system is provided, including an exhaust fan and an exhaust pipe. The exhaust fan is connected to the exhaust pipe and is located at the top of the mine. The exhaust fan is installed in a horizontally arranged air guide tube, which is rotatably connected to the exhaust pipe and driven to rotate by a drive mechanism. The exhaust pipe is provided with a plurality of exhaust holes, and each exhaust hole is provided with a removable plug.

[0008] With this solution, the exhaust fan is installed above the mine shaft and exhausts air horizontally through the air duct. The air duct can rotate according to the wind direction to avoid the influence of external airflow. The exhaust vents can be blocked or opened as needed to exhaust heat in a suitable location and ensure the pressure in the exhaust pipe.

[0009] Preferably, the exhaust pipe includes several detachably connected pipe sections, which are connected by flanges; the exhaust vents are provided on each pipe section.

[0010] With this solution, pipe sections can be added or removed according to the required depth of the mine, making disassembly and assembly convenient.

[0011] Preferably, the plug is rotatably connected to the pipe wall above the vent hole, and the friction between the plug and the pipe wall is greater than the weight of the plug.

[0012] With this solution, the vent can be opened and closed simply by rotating the plug, making it more convenient to use.

[0013] Preferably, the air guide duct has a T-shaped structure, and an external gear ring is provided on the outer periphery of the bottom of the air guide duct; the drive mechanism is located at the top of the exhaust pipe and meshes with the external gear ring.

[0014] With this solution, the drive mechanism is a servo motor, which can rotate the air guide tube according to the current wind direction, so that it is opposite to the wind direction or perpendicular to the wind direction, thus avoiding the impact of external airflow on the exhaust.

[0015] Preferably, the air duct has a through structure, and the openings at both ends of the air duct are funnel-shaped.

[0016] With this solution, when rotated to align with the wind direction, the external wind speed can be used to increase the wind speed inside the air duct, and the Bernoulli principle can be used to extract air from the well, which helps to reduce energy consumption; the flared shape can further concentrate the airflow and increase the wind speed inside the air duct.

[0017] Preferably, it also includes a wind vane, which is rotatably connected to the top of the wind duct for detecting the current wind direction.

[0018] With this solution, the wind vane can detect the current wind direction, making it easier to control the angle of the air duct; its location at the top of the air duct can prevent the airflow from the air duct from affecting the wind vane.

[0019] Preferably, a potentiometer is fixed to the top of the air duct, and the wind vane is connected to the shaft of the potentiometer.

[0020] With this solution, the potentiometer can detect the current wind vane's pointing angle, thereby controlling the drive mechanism to precisely control the air duct.

[0021] According to one embodiment of this application, the beneficial effects of using this mine ventilation and heat exhaust system are that the exhaust fan can be installed at the top of the mine and the external airflow can be used to improve the exhaust effect, which helps to reduce energy consumption and increase the service life of the exhaust fan; the exhaust pipe can be assembled arbitrarily, and the corresponding exhaust holes can be opened or closed as needed to ensure the pressure inside the pipe and improve the heat exhaust effect.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] like Figures 1 to 4 As shown, a mine ventilation and heat dissipation system in one embodiment of this application includes an exhaust fan 110 and an exhaust pipe 200. The exhaust fan 110 is connected to the exhaust pipe 200 and is located at the top of the mine. The exhaust fan 110 is installed in a horizontally arranged air guide duct 120. The air guide duct 120 is rotatably connected to the exhaust pipe 200 and driven to rotate by a drive mechanism 132. The exhaust pipe 200 is provided with a plurality of exhaust holes 211, and each exhaust hole 211 is provided with a removable plug 212.

[0029] In this embodiment, the exhaust fan 110 is installed above the mine shaft and exhausts air horizontally through the air duct 120. The air duct 120 can rotate according to the wind direction, avoiding the influence of external airflow, that is, preventing wind from blowing directly into the air duct 120 and causing air inrush. The exhaust hole 211 can be blocked or opened as needed to exhaust heat in a suitable position, ensuring the pressure in the exhaust pipe 200.

[0030] In this embodiment, the exhaust fan 110 is an axial flow fan, which ensures that it has a large suction force. The airflow blown out by the exhaust fan 110 is consistent with the axis of the air guide duct 120 or the arrangement direction of the exhaust pipe 200. It is arranged vertically upward, which can guide the airflow to both sides of the air guide duct 120 for discharge.

[0031] In one embodiment of this application, the exhaust pipe 200 includes several detachably connected pipe sections 210, which are connected by flanges, and exhaust holes 211 are provided on the pipe sections 210. The pipe sections 210 can be added or removed according to the required depth of the mine, which facilitates disassembly and assembly.

[0032] The exhaust duct 200 is made of galvanized pipe or stainless steel pipe. The appropriate diameter is selected according to the mine depth or the volume inside the mine, and the exhaust fan 110 with the corresponding power is selected according to the diameter.

[0033] In one embodiment of this application, the plug 212 is rotatably connected to the wall of the exhaust pipe 200 above the exhaust hole 211, and the friction between the plug 212 and the wall of the exhaust pipe 200 is greater than the weight of the plug 212. The exhaust hole 211 can be opened and closed simply by rotating the plug 212, making it more convenient to use.

[0034] A rubber pad is provided on the side of the plug 212 that contacts the exhaust pipe 200, which can increase friction and improve the sealing effect after plugging.

[0035] In one embodiment of this application, the air duct 120 has a T-shaped structure, and the exhaust fan 110 is horizontally arranged inside the air duct 120. An external gear ring 131 is provided on the outer periphery of the bottom of the air duct 120, and the drive mechanism 132 is disposed on the top of the exhaust pipe 200 and meshes with the external gear ring 131. The drive mechanism 132 is a servo motor, which can rotate the air duct 120 according to the current wind direction, so that it is opposite to the wind direction or perpendicular to the wind direction, so as to avoid the external airflow affecting the exhaust.

[0036] In one embodiment of this application, the air duct 120 is a through structure, and the openings at both ends of the air duct 120 are funnel-shaped. When rotated to be in the same direction as the wind, the external wind speed can be used to increase the wind speed inside the air duct 120, and the air inside the well can be extracted using Bernoulli's principle, which helps to reduce energy consumption; the funnel shape can further concentrate the airflow and increase the wind speed inside the air duct 120.

[0037] In one embodiment of this application, a wind vane 140 is further included. The wind vane 140 is rotatably connected to the top of the air guide 120 and is used to detect the current wind direction. The wind vane 140 can detect the current wind direction to facilitate the control of the angle of the air guide 120; being located at the top of the air guide 120 can avoid the influence of the airflow of the air guide 120 on the wind vane 140.

[0038] In one embodiment of this application, a potentiometer is fixed to the top of the air guide duct 120, and a wind vane 140 is connected to the rotating shaft of the potentiometer. The potentiometer can detect the current pointing angle of the wind vane 140, thereby controlling the drive mechanism 132 to precisely control the air guide duct 120. A control mechanism is also included, which can collect the signal from the potentiometer and control the air guide duct 120 to rotate forward or backward according to the signal, so that its air outlet faces away from the oncoming wind direction, utilizing wind speed to reduce energy consumption.

[0039] According to this embodiment, the beneficial effects of using this mine ventilation and heat dissipation system are that the exhaust fan can be installed at the top of the mine and the external airflow can be used to improve the ventilation effect, which helps to reduce energy consumption and increase the service life of the exhaust fan; the exhaust pipe can be assembled arbitrarily, and the corresponding exhaust holes can be opened or closed as needed to ensure the pressure inside the pipe and improve the heat dissipation effect.
