Description

Technical Field

[0001] This invention relates to the field of nitrogen generator technology, specifically to a nitrogen generator equipped with a mining cooling mechanism. Background Technology

[0002] A nitrogen generator is an industrial device that uses air as raw material and employs physical separation technology to directly produce nitrogen on-site. It can separate approximately 78% of the nitrogen in the air from oxygen and other gases, providing users with a nitrogen source with stable and controllable purity, flow rate, and pressure.

[0003] In the mining industry, safe production is the core of enterprise production and operation. Mining nitrogen generators are widely used in underground fire prevention and extinguishing. Through nitrogen inerting and cooling technology, they can improve the fire prevention and extinguishing effect and equipment operating efficiency. However, the existing nitrogen injection methods still have shortcomings in suppressing coal spontaneous combustion and preventing gas explosions. Moreover, the demand for nitrogen concentration and supply varies in different areas of the mine, and it is necessary to zone and deliver nitrogen according to actual working conditions. In addition, when traditional sensors are used in special underground environments, there is a safety hazard of generating electric sparks, which can easily have an adverse impact on the safety of underground operations and make it difficult to meet the high safety requirements.

[0004] To address the aforementioned issues, we propose a nitrogen generator equipped with a mining cooling mechanism. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a nitrogen generator with a mining cooling mechanism. It adopts a purely mechanical linkage structure to automatically adjust the nitrogen supply to different locations in the mine, eliminating the need for electrical control components and traditional sensors. This fundamentally avoids the generation of electrical sparks, significantly improves underground explosion-proof safety, and is more suitable for the high-risk working environment of coal mines.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a nitrogen generator with a mining cooling mechanism, comprising an air compressor, a buffer tank, an adsorption combination tower, a nitrogen process tank, and a nitrogen storage tank. The nitrogen storage tank has a tank structure with upper and lower inner walls. A cooler is provided on the rear side of the nitrogen storage tank. A connecting main pipe is fixedly installed on the lower side of the surface of the nitrogen storage tank. A connecting branch pipe is fixedly installed on the end of the connecting main pipe away from the nitrogen storage tank. Several outlet components are provided on the side of the connecting branch pipe away from the nitrogen storage tank. The outlet component includes a combined pipe fixedly installed on one side of the surface of the connecting branch pipe, and a connecting cylinder is sleeved on the side of the combined pipe away from the connecting branch pipe, and an air outlet pipe is sleeved on the side of the connecting cylinder away from the combined pipe. An adjustment component is provided on the surface of the connecting cylinder. The adjustment assembly includes a conversion shell fixedly installed on the surface of the connecting cylinder, and a movable plate movably installed on the lower side of the inner wall of the conversion shell. A reset damping spring is fixedly installed at each of the four corners of the bottom of the movable plate. Pressure start-up components are provided on the left and right sides of the inner wall of the conversion shell, and temperature start-up components are provided on the front and rear sides of the inner wall of the conversion shell. A liquid guide plate is fixedly installed on one side of the inner wall of the connecting cylinder located on the conversion shell. Right-angle guide blocks are fixedly installed on the opposite sides of the surface of the liquid guide plate located on the hole. A gate is slidably installed on the inner wall of the two right-angle guide blocks.

[0007] Furthermore, the outlet of the air compressor is connected to the inlet of the buffer tank via a pipeline, the outlet of the buffer tank is connected to the inlet of the adsorption combination tower via a pipeline, the outlet of the adsorption combination tower is connected to the inlet of the nitrogen process tank via a pipeline, and the outlet of the nitrogen process tank is connected to the inlet of the nitrogen storage tank via a pipeline.

[0008] Furthermore, the input end of the cooler extends through to the upper inner wall of the nitrogen storage tank, while the output end of the cooler extends through to the lower inner wall of the nitrogen storage tank, and the upper inner wall of the nitrogen storage tank is connected to the output end of the nitrogen process tank.

[0009] Furthermore, three stress damping springs are fixedly installed on the upper part of the lower inner wall of the nitrogen storage tank, and the output ends of the three stress damping springs are fixedly connected to a sealing disc. The sealing disc, together with the squeezing effect of the stress damping springs, can ensure the stability of the nitrogen pressure output from the nitrogen storage tank.

[0010] Furthermore, both the combined pipe and the connecting main pipe are pipe structures with valves. The surface of the connecting cylinder is provided with multiple fixing bolts, which are used to achieve a stable connection between the combined pipe and the vent pipe. The surface of the vent pipe is provided with multiple vent holes.

[0011] Furthermore, glass windows are provided on opposite sides of the surface of the conversion shell, and the temperature start-up component is located on the side closer to the glass window. The fixed ends of the four reset damping springs are all fixedly connected to the lower side of the inner wall of the conversion shell. The line formed by the projection of the two pressure start-up components onto the same plane is perpendicular to the line formed by the projection of the two temperature start-up components onto the same plane.

[0012] Furthermore, the gate is a structure with a protruding block integrally formed on one side of a plate. The upper part of the gate passes through the inner wall of the connecting cylinder and the surface of the conversion shell from top to bottom, extending to the internal cavity of the conversion shell. The gate is located on the upper part of the inner wall of the conversion shell and is fixedly connected to the bottom of the moving plate by welding or bolt fastening to ensure a firm connection and synchronized operation. Under the elastic tension of several reset damping springs, the gate is pulled to the initial position. At this time, the gate and the liquid guide plate are arranged in an alternating manner, that is, neither the plate body nor the protruding block of the gate blocks the liquid passage on the liquid guide plate, thereby reliably ensuring the normal liquid passage effect of the liquid guide plate and ensuring that the medium can pass smoothly.

[0013] Furthermore, the pressure-starting assembly includes a piston cylinder fixedly mounted on the surface of the conversion housing, a pushing piston movably mounted on the inner wall of the piston cylinder, and fixed vertical plates fixedly mounted on both sides of the inner wall of the conversion housing opposite to the piston cylinder. Two fixed vertical plates are mounted with two rotating shafts that rotate together on opposite sides. Two gears are fixedly mounted on opposite sides of the shaft walls of the two rotating shafts. The two gears that push the piston surface close to the piston cylinder have two pulling gear plates fixedly mounted on their lower surfaces. On the rotating shaft away from the piston cylinder, a pulling rope is wound between the two corresponding gears. A connecting frame is fixedly mounted at the top center of the moving plate. A fixed pulley is fixedly mounted on the upper part of the inner wall of the conversion shell. The pulling rope passes over the fixed pulley and is fixedly connected to the top of the connecting frame.

[0014] Furthermore, the temperature-initiating assembly includes an expansion cylinder fixedly installed inside one side of the conversion housing. A jacking block is slidably installed on the lower side of the inner wall of the expansion cylinder. The lower side of the inner wall of the jacking block is filled with expansion liquid. A limiting telescopic rod is fixedly installed on the top of the jacking block. The fixed end of the limiting telescopic rod extends through to the top surface of the expansion cylinder, and the fixed end of the limiting telescopic rod is fixedly connected to the upper side of the inner wall of the conversion housing. A pushing frame is fixedly installed on the top of the jacking block. The pushing frame is arranged around the inner wall of the connecting frame. A moving port is opened on the surface of the expansion cylinder on one side of the pushing frame. The pushing frame can slide within the moving port. The thickness of the jacking block is sufficient to always cover the moving port during movement to prevent leakage from the moving port.

[0015] Furthermore, the gear tooth diameter on the side closer to the piston cylinder is five times that on the side farther from the piston cylinder. The rotation and stroke are amplified by the ratio of the large and small gears, which pulls the gear plate to mesh with the corresponding gear.

[0016] Compared with the prior art, the present invention provides a nitrogen generator with a mining cooling mechanism, which has the following beneficial effects: 1. This device adopts a purely mechanical linkage structure to automatically adjust the nitrogen supply at different locations in the mine. It does not require electrical control components or traditional sensors, thus avoiding the generation of electrical sparks at the source, significantly improving the explosion-proof safety underground, and is more suitable for the high-risk working environment in coal mines.

[0017] 2. This device automatically allocates nitrogen flow according to the actual needs of different areas of the mine through mechanical linkage, realizing zoned, on-demand, and precise nitrogen supply. It solves the problems of uneven nitrogen supply, nitrogen waste, and poor inerting effect of traditional nitrogen injection methods, and improves nitrogen utilization and fire prevention and extinguishing efficiency.

[0018] 3. The device simultaneously cools the nitrogen during the nitrogen transport process. Low-temperature nitrogen can further enhance the cooling effect on the coal body, improve the ability to inertize and suppress combustion and inhibit gas explosion, while reducing the energy consumption of the nitrogen generator and improving the overall energy efficiency of the equipment.

The air compressor 1, buffer tank 2, adsorption tower 3, nitrogen process tank 4, nitrogen storage tank 5, and supporting pipelines of this application are all integrated and installed in a protective shell with an opening. The shell adopts a modular box-type structure design. The outlet of the air compressor 1 is connected to the inlet of the buffer tank 2 through a pipeline, while the outlet of the buffer tank 2 is connected to the inlet of the adsorption tower 3 through a pipeline.

The air compressor 1, as an air source supply component, has its outlet sealed and connected to the inlet of the buffer tank 2 through a pipeline. It is used to draw in outside air and compress it, then deliver the compressed high-pressure air to the buffer tank 2. The buffer tank 2 is used to buffer and stabilize the pressure of the high-pressure air delivered by the air compressor 1, eliminating air pressure waves. The system can simultaneously separate some liquid impurities from the air. Its outlet is sealed and connected to the inlet of the adsorption tower 3 through a pipeline, so that the buffered and pressure-stabilized air can be smoothly delivered to the adsorption tower 3. The adsorption tower 3 is the core component of nitrogen-oxygen separation. It is used to selectively adsorb and separate the input air, adsorbing and removing impurities such as oxygen, carbon dioxide, and moisture in the air to obtain crude nitrogen. Its outlet is sealed and connected to the inlet of the nitrogen process tank 4 through a pipeline, so that the separated crude nitrogen can be delivered to the nitrogen process tank 4. The nitrogen process tank 4 is used to further stabilize the pressure and remove impurities from the crude nitrogen, so that the purity and pressure of the nitrogen can meet the preset process requirements to form qualified nitrogen. Its outlet is sealed and connected to the inlet of the nitrogen storage tank 5 through a pipeline, so that the qualified nitrogen can be delivered to the nitrogen storage tank 5 for storage, so that it can be used as needed later. All the above components are connected in sequence and sealed by pipelines. Each pipeline is made of corrosion-resistant and high-pressure-resistant material to ensure no leakage during gas transportation. Air compressor 1, buffer tank 2, adsorption combination tower 3, and nitrogen process tank 4 work together to complete the core processes of air compression, pressure buffering, nitrogen-oxygen separation, and nitrogen purification and stabilization, respectively. Finally, nitrogen is stored through nitrogen storage tank 5, ensuring the smooth preparation of nitrogen throughout the process and meeting subsequent usage requirements. like Figures 1 to 12 As shown, the nitrogen storage tank 5 has a tank structure with upper and lower inner walls.

The sealing disc 502, together with the compression effect of the stress damping springs 501, can ensure the stability of the nitrogen pressure output from the nitrogen storage tank 5; like Figures 1 to 12 As shown, a main connecting pipe 7 is fixedly installed on the lower side of the surface of the nitrogen storage tank 5.

The combination pipe 901 and the air outlet pipe 904 are stably connected by fixing bolts 9031. Multiple air outlet holes 9041 are opened on the surface of the air outlet pipe 904. An adjustment assembly 10 is provided on the surface of the connecting cylinder 903. The adjustment assembly 10 includes a conversion shell 1001 fixedly installed on the surface of the connecting cylinder 903. Glass windows 13 are provided on opposite sides of the surface of the conversion shell 1001. The temperature start assembly 12 is provided on the side closer to the glass window 13. A movable plate 1002 is movably installed on the lower side of the inner wall of the conversion shell 1001. Reset damping springs 1003 are fixedly installed at the four corners of the bottom of the movable plate 1002. The fixed ends of the four reset damping springs 1003 are fixedly connected to the lower side of the inner wall of the conversion shell 1001. Pressure start assemblies 11 are provided on the left and right sides of the inner wall of the conversion shell 1001, and temperature start assemblies 12 are provided on the front and rear sides of the inner wall of the conversion shell 1001. The line formed by the projection of two pressure start assemblies 11 onto the same plane is perpendicular to the line formed by the projection of two temperature start assemblies 12 onto the same plane. A liquid guide plate 1004 is fixedly installed on the inner wall of the connecting cylinder 903 on one side of the conversion shell 1001, and right-angle guide blocks 1005 are fixedly installed on the surface of the liquid guide plate 1004 on both sides opposite to the hole. A gate plate 1006 is slidably installed on the inner wall of the two right-angle guide blocks 1005. The gate 1006 is a structure with a protruding block integrally formed on one side of a plate. The upper part of the gate 1006 passes through the inner wall of the connecting cylinder 903 and the surface of the conversion shell 1001 from top to bottom, extending to the internal cavity of the conversion shell 1001. The gate 1006 is located on the upper part of the inner wall of the conversion shell 1001 and is fixedly connected to the bottom of the moving plate 1002 by welding or bolt fastening to ensure a firm connection and synchronous operation. Under the elastic tension of several reset damping springs 1003, the gate 1006 is pulled to the initial position. At this time, the gate 1006 and the liquid guide plate 1004 are arranged in an alternating manner, that is, neither the plate body nor the protruding block of the gate 1006 blocks the liquid passage on the liquid guide plate 1004, thereby reliably ensuring the normal liquid passage effect of the liquid guide plate 1004 and ensuring that the medium can pass smoothly. The pressure-activated assembly 11 includes a piston cylinder 1101 fixedly mounted on the surface of a conversion housing 1001. A push piston 1102 is movably mounted on the inner wall of the piston cylinder 1101. Fixed vertical plates 1103 are fixedly mounted on opposite sides of the inner wall of the conversion housing 1001 on both sides of the piston cylinder 1101.

The gear 1105 closer to the piston cylinder 1101 has a tooth diameter five times that of the gear 1105 farther from the piston cylinder 1101. The gears 1105 are connected via a large and small gear 1105. The ratio of 105 amplifies the rotation and stroke. Pulling tooth plates 1106 are fixedly installed on the lower side of two gears 1105 that push the surface of piston 1102 and are located near piston cylinder 1101. Pulling tooth plates 1106 mesh with corresponding gears 1105. Pulling ropes 1107 are wound between two corresponding gears 1105 on the rotating shaft 1104 away from piston cylinder 1101.

A limiting telescopic rod 1203 is fixedly installed on the top of the push block 1202. The fixed end of the limiting telescopic rod 1203 extends through to the top surface of the expansion cylinder 1201 and is fixedly connected to the upper side of the inner wall of the conversion housing 1001. A push frame 1204 is fixedly installed on the top of the push block 1202. The push frame 1204 is arranged around the inner wall of the connecting frame 1108. A moving port 1205 is opened on the surface of the expansion cylinder 1201 on one side of the push frame 1204. The push frame 1204 can slide in the moving port 1205. The thickness of the push block 1202 is sufficient to always cover the moving port 1205 during movement to prevent leakage from the moving port 1205.

[0023] The working principle of the above embodiments is as follows: When the device is in use, the air compressor 1 is started first. The air compressor 1 compresses the outside air and sends it through the pipeline to the buffer tank 2 for pressure stabilization and preliminary gas-liquid separation. After buffering and stabilizing, the air enters the adsorption combination tower 3. The adsorption combination tower 3 adsorbs and removes impurities such as oxygen, carbon dioxide, and moisture in the air to generate crude nitrogen. The crude nitrogen then enters the nitrogen process tank 4 for further pressure stabilization and purification to form qualified nitrogen that meets the process requirements. Finally, the qualified nitrogen is transported to the nitrogen storage tank 5 for storage. The above working principle is a mature existing technology and will not be described in detail in this application. After nitrogen is prepared, the cooler 6 is started. Its input end draws the prepared nitrogen from the upper inner wall of the nitrogen storage tank 5, and its output end releases the cooled nitrogen to the lower inner wall of the nitrogen storage tank 5, thereby ensuring the cooling effect of the nitrogen. At the same time, the stress damping spring 501 inside the nitrogen storage tank 5 always applies a downward squeezing force to the sealing plate 502. When nitrogen is output, the sealing plate 502 maintains dynamic balance under the combined action of spring force and gas pressure, thereby buffering the fluctuation of output pressure and ensuring the stability of nitrogen output pressure. When nitrogen needs to be supplied to the gas consumption point, the valve on the main connecting pipe 7 is opened. The nitrogen in the nitrogen storage tank 5 enters the connecting branch pipe 8 through the main connecting pipe 7 and is distributed to each outlet component 9. After entering the combination pipe 901 of the outlet component 9, the nitrogen flows through the connecting cylinder 903 and is finally discharged from the outlet hole 9041 on the outlet pipe 904. It is inertly cooled and protected in the mine. During this process, the fixing bolt 9031 ensures that the connection between the combination pipe 901, the connecting cylinder 903 and the outlet pipe 904 is stable and prevents leakage. During the nitrogen extraction process, the regulating component 10 automatically adjusts the opening of the liquid guide plate 1004 according to the pressure and temperature set at the mine location to achieve precise control of the output flow rate. When a gas leak occurs at the location of the conversion housing 1001, a negative pressure is generated. This pressure is transmitted to the piston cylinder 1101, pulling and pushing the piston 1102 to move outward from the conversion housing 1001. The piston 1102 drives the pull gear plate 1106, which is fixedly connected to it, to move. The pull gear plate 1106 drives the gear 1105, which meshes with it and is located near the piston cylinder 1101, to rotate. Since the rotating shaft 1104, which is away from the piston cylinder 1101, is fixedly connected to the frame 1108 by the pull rope 1107, when it is close to the piston cylinder 1101... When gear 1105 rotates, under the accelerated transmission of gear 1105 on the side away from piston cylinder 1101, the pulling rope 1107 passes over the fixed pulley 1109 and pulls the moving plate 1002, which is fixedly connected to the connecting frame 1108, to move upward. The moving plate 1002 drives the gate 1006, which is fixedly connected to its bottom, to slide upward under the guidance of the right-angle guide block 1005, thereby reducing the blocking area of ​​the gate 1006 on the liquid guide port plate 1004, thereby increasing the flow of nitrogen, increasing the output pressure, and achieving the protective effect of inert gas. When the temperature of the ore increases at the setting position of the conversion shell 1001, posing a risk of combustion, the expansion liquid in the expansion cylinder 1201 of the temperature activation component 12 expands due to heat, pushing the jacking block 1202 to slide upward. The jacking block 1202 drives the pusher frame 1204, which is fixedly connected to it, to move upward. The pusher frame 1204 surrounds the inner wall of the connecting frame 1108. When it moves upward, it pushes the connecting frame 1108 to move upward, thereby driving the moving plate 1002 to move upward. The moving plate 1002 also drives the gate plate 1006 to slide upward, reducing the opening of the liquid guide plate 1004 and increasing the flow of nitrogen. Conversely, when the temperature decreases, the expansion liquid contracts. Under the pulling force of the reset damping spring 1003, the moving plate 1002 drives the gate plate 1006 to reset downward, reducing the opening.

[0024] The linkage design of the pressure start-up component 11 and the temperature start-up component 12 allows the opening of the liquid guide plate 1004 to be automatically adjusted by the up-and-down movement of the gate 1006, regardless of whether the problem is a gas leak or a high temperature. This ensures precise control of the nitrogen output flow rate and stable gas supply. The connection between the two pressure start-up components 11 and the connection between the two temperature start-up components 12 are perpendicular to each other. This orthogonal arrangement ensures that the detection and control of pressure and temperature do not interfere with each other, improving the accuracy and reliability of the adjustment.

[0025] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
