Description

Technical Field

[0001] This utility model relates to the field of explosion-proof locomotive technology, specifically to an explosion-proof locomotive exhaust gas purification device. Background Technology

[0002] Explosion-proof locomotives are special vehicles designed for transportation in mine roadways where there is a risk of gas and coal dust explosions. Their core feature is the explosion-proof system comprised of a special explosion-proof power supply unit and explosion-proof motors and electrical components. This type of locomotive achieves precise control through IGBT chopper or frequency converter speed regulation technology. The DC power from the battery drives the motor through explosion-proof components. The power supply unit uses a bipolar structure and acid-resistant insulating materials to effectively prevent short-circuit sparks and electrolyte leakage.

[0003] For example, the authorization notice number "CN222788817U" is for a kind of exhaust gas purification device, which can perform preliminary filtration and cooling of particles in exhaust gas. It uses air sprayed from the blower pipe to atomize the water discharged from the water pipe. Existing exhaust gas purification devices are suitable for use with exhaust gas generated by combustion in industrial plants. Because the amount of exhaust gas generated by combustion in factories is very large, there is enough space to install water cooling and air cooling atomization equipment. However, explosion-proof locomotives usually work in narrow and limited shafts, so there is no extra space to install water tanks for cooling operations. In addition, to ensure safety, explosion-proof locomotives generally do not add more devices or equipment on the outside. This makes it unsuitable for use with exhaust gas purification devices that are too large. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing exhaust gas purification devices for explosion-proof locomotives usually operate in narrow and limited shafts, so there is no extra space to install a water tank for cooling operations. This results in exhaust gas purification devices that are too bulky to be used on explosion-proof locomotives. Therefore, this utility model proposes an exhaust gas purification device for explosion-proof locomotives.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an explosion-proof locomotive exhaust gas purification device, including an exhaust pipe, an air inlet and an air outlet. One end of the exhaust pipe is fixedly connected to a small exhaust gas cooling structure, and the other end of the exhaust pipe is provided with an exhaust gas filtration and purification structure. An exhaust gas purification device mounting support structure is provided on the outside of the exhaust pipe.

[0007] The exhaust pipe is made of a tight stainless steel metal pipe and is designed in a curved shape to make the most of the limited space. The intake pipe is used to connect to the exhaust pipe of the explosion-proof locomotive, while the exhaust port is used to discharge the purified exhaust gas.

[0008] Preferably, the small exhaust gas cooling structure includes a sleeve and a connecting pipe. The connecting pipe is fixedly connected to the end of the exhaust pipe. A vent pipe is fixedly connected to the inner side of the connecting pipe. Multiple interceptor plates are fixedly connected inside the vent pipe. A heat-conducting layer is fixedly installed inside the sleeve. A heat transfer rod is fixedly installed inside the heat-conducting layer. Multiple heat dissipation fins are fixedly installed at the other end of the heat transfer rod.

[0009] This device uses a welded connection between the exhaust pipe and the air inlet to cool the high temperature of the explosion-proof vehicle exhaust. The connecting plates are staggered and welded to the inner wall of the vent pipe. The interceptor plate increases the time and distance that the explosion-proof vehicle exhaust flows inside the vent pipe, enhancing heat exchange efficiency. The heat-conducting layer is a thin layer of metallic copper wrapped between the sleeve and the vent pipe. Metallic copper has excellent thermal conductivity, which can be used to transfer the high temperature of the explosion-proof vehicle exhaust flowing through the vent pipe to the outside for heat exchange.

[0010] Preferably, a docking flange is fixedly installed at the other end of the connecting pipe, and an air inlet is fixedly connected to the other end of the docking flange.

[0011] This setting uses multiple bolts on the outside of the flange to connect the pipe and the air inlet. Therefore, a large amount of exhaust gas generated by the explosion-proof locomotive will flow directly along the air inlet to the inside of the connecting pipe.

[0012] Preferably, the exhaust gas filtration and purification structure includes a disassembly pipe and a mounting base. The mounting base is fixedly connected to the other end of the exhaust pipe. An installation screw is threadedly connected to the inner side of the mounting base. A support pipe is fixedly connected to the other end of the installation screw. A disassembly pipe is fixedly installed at the other end of the support pipe. Sealing rings are fixedly sleeved at both ends of the disassembly pipe. An adsorption layer is fixedly installed inside the disassembly pipe. A purification layer is fixedly installed on the inner side of the disassembly pipe.

[0013] This mounting base features internal grooves that align with the threads on the outer wall of the mounting tube, allowing the disassembly tube to be inserted laterally into both mounting bases. Installation or removal is achieved by laterally twisting the disassembly tube. The support tube secures the internal disassembly tube. The sealing ring is made of natural rubber. After the sealing ring is tightened onto the mounting base at both ends of the disassembly tube, it abuts against the end of the support tube for a tight seal. The adsorption layer is made of multi-stage activated carbon, which effectively adsorbs and removes impurities from the exhaust gas of the explosion-proof locomotive. The purification layer is made of multi-stage fiber filters, which further filter and purify pollutants and dust inside the exhaust gas of the explosion-proof locomotive.

[0014] Preferably, the multiple purification layers and adsorption layers are stacked alternately, and the other end of the mounting base is connected to the inside of the air outlet.

[0015] Preferably, the exhaust gas purification device mounting support structure includes a fixing hoop and vertical beams. The fixing hoop is movably sleeved on the outer wall of the exhaust pipe. The two sides of the fixing hoop are connected to overlapping blocks by bolts and threads. Multiple vertical beams are fixedly connected to the outer wall of the fixing hoop.

[0016] The fixing hoop is a thin, semi-circular metal hoop made of aluminum alloy that can be manually pried open. After being pried open, the fixing hoop is placed on the outer wall of the exhaust pipe, air inlet, and air outlet. Then, bolts are used to tighten it at the overlapping block at the end of the fixing hoop. The vertical beam is made of metal steel pipe and welded to the outside of the fixing hoop. The other end of the vertical beam can be installed near the exhaust gas emission position of the explosion-proof locomotive using bolts or other fixing parts.

[0017] The present invention proposes an explosion-proof locomotive exhaust gas purification device, the advantages of which are as follows: the connecting plates are staggered and welded to the inner wall of the vent pipe; the intercepting plate increases the time and distance that the explosion-proof locomotive exhaust gas flows inside the vent pipe; the heat-conducting layer is a thin layer of metal copper wrapped between the sleeve and the vent pipe, which can be used to transfer the high temperature of the explosion-proof locomotive exhaust gas flowing inside the vent pipe to the outside through heat exchange, and rely on the heat dissipation fins to diffuse in the air. In this way, the exhaust gas generated by the explosion-proof locomotive is fully and evenly cooled in a limited space, ensuring that the temperature of the exhaust gas is more conducive to subsequent purification treatment. The entire cooling structure is achieved by heat exchange, which occupies little space and does not require additional water cooling equipment, making the explosion-proof locomotive exhaust gas purification device more applicable.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] Example:

[0027] Please see Figure 1-6 In this embodiment, an explosion-proof locomotive exhaust gas purification device includes an exhaust pipe 1, an air inlet 2, and an air outlet 3. One end of the exhaust pipe 1 is fixedly connected to a small exhaust gas cooling structure 4. The exhaust pipe 1 is made of a tight stainless steel metal pipe and is designed in a curved shape to maximize the use of limited space. The air inlet 2 is used to connect to the exhaust pipe of the explosion-proof locomotive, while the air outlet 3 is used to discharge the purified exhaust gas. The other end of the exhaust pipe 1 is provided with an exhaust gas filtration and purification structure 5, and the outside of the exhaust pipe 1 is provided with an exhaust gas purification device mounting support structure 6.

[0028] The small exhaust gas cooling structure 4 includes a sleeve 41 and a connecting pipe 42. The connecting pipe 42 is fixedly connected to the end of the exhaust pipe 1 and is welded between the exhaust pipe 1 and the air inlet 2. It is used to cool the high temperature of the exhaust gas from the explosion-proof vehicle. A vent pipe 43 is fixedly connected to the inside of the connecting pipe 42. Multiple intercepting plates 44 are fixedly connected inside the vent pipe 43. The connecting plates 44 are staggered and welded to the inner wall of the vent pipe 43. The intercepting plates 44 can increase the time and distance that the exhaust gas from the explosion-proof vehicle flows inside the vent pipe 43, thereby enhancing the heat exchange efficiency. A heat-conducting layer 45 is fixedly installed on the inside of the sleeve 41. The heat-conducting layer 45 is wrapped around the sleeve 41 and the vent pipe 43. A thin layer of metallic copper is formed between the 3 and 4. Metallic copper has excellent thermal conductivity. The thermal conductive layer 45 can be used to transfer the high temperature of the exhaust gas flowing through the vent pipe 43 to the outside through heat exchange. The heat transfer rod 46 is also a hollow metal copper tube. The heat transfer rod 46 further transfers the temperature to the multiple rows of heat dissipation fins 47 set on the outside. Finally, the heat dissipation fins 47 diffuse into the air to complete the heat dissipation requirements. In this way, the exhaust gas generated by the explosion-proof locomotive is fully and evenly cooled in a limited space, ensuring that the temperature of the exhaust gas is more conducive to subsequent purification treatment. The heat transfer rod 46 is fixedly installed on the inner side of the thermal conductive layer 45, and multiple heat dissipation fins 47 are fixedly installed on the other end of the heat transfer rod 46.

[0029] The other end of the connecting pipe 42 is fixedly installed with a docking flange 7. The docking flange 7 is connected to the connecting pipe 42 and the air inlet 2 by multiple bolts on the outside. Therefore, a large amount of exhaust gas generated by the explosion-proof locomotive will flow directly along the air inlet 2 to the inside of the connecting pipe 42. The other end of the docking flange 7 is fixedly connected to the air inlet 2.

[0030] The exhaust gas filtration and purification structure 5 includes a disassembly pipe 51 and a mounting base 57. The mounting base 57 is fixedly connected to the other end of the exhaust pipe 1. The mounting base 57 is connected to the end of the exhaust outlet 3 and the exhaust pipe 1. The mounting base 57 has grooves inside that match the threads on the outer wall of the mounting screw tube 54, so the disassembly pipe 51 can be inserted laterally into the mounting bases 57 on both sides. Then, installation or disassembly is achieved by turning the disassembly pipe 51 laterally. The mounting base 57 is threadedly connected to the mounting screw tube 54. The other end of the mounting screw tube 54 is fixedly connected to a support pipe 53. The support pipe 53 is used to fix the disassembly pipe 51 inside. The other end of the support pipe 53 is fixedly installed with the disassembly pipe 51. Both ends of the disassembly tube 51 are fixedly fitted with sealing rings 52, which are made of natural rubber. After the sealing rings 52 are tightened onto the mounting base 57 at both ends of the disassembly tube 51, they will press against the end of the support tube 53 to achieve a tight seal. An adsorption layer 56 is fixedly installed inside the disassembly tube 51. The adsorption layer 56 is made of multi-stage activated carbon material. Through the excellent adsorption effect of activated carbon, impurities in the exhaust gas of the explosion-proof locomotive are adsorbed and removed. A purification layer 55 is fixedly installed on the inner side of the disassembly tube 51. The purification layer 55 is made of multi-stage fiber filter, which can further filter and purify the pollutants and dust inside the exhaust gas of the explosion-proof locomotive, ensuring that the pollution of the exhaust gas discharged later will be greatly reduced.

[0031] Multiple purification layers 55 and adsorption layers 56 are stacked and interleaved, and the other end of the mounting base 57 is connected to the inside of the air outlet 3.

[0032] The exhaust gas purification device installation support structure 6 includes a fixing hoop 61 and vertical beams 63. The fixing hoop 61 is movably fitted onto the outer wall of the exhaust pipe 1. The fixing hoop 61 is a relatively thin, semi-circular metal hoop made of aluminum alloy that can be manually pried open. After being pried open, the fixing hoop 61 is fitted onto the outer wall of the exhaust pipe 1, the air inlet 2, and the air outlet 3. Then, bolts are tightened at the end of the fixing hoop 61 at the overlapping block 62 for fixation. The two sides of the fixing hoop 61 are connected to the overlapping block 62 by bolt threads. Multiple vertical beams 63 are fixedly connected to the outer wall of the fixing hoop 61. The vertical beams 63 are made of metal steel pipe and welded to the outside of the fixing hoop 61. The other end of the vertical beam 63 can be installed near the exhaust gas emission position of the explosion-proof locomotive by bolts or other fixing parts.

[0033] Working principle:

[0034] The explosion-proof locomotive exhaust gas purification device is installed at the end of the exhaust pipe of the explosion-proof locomotive. It uses the method of cooling first and then filtering and purifying to treat the exhaust gas of the explosion-proof locomotive. Because the explosion-proof locomotive needs to be used in a space-limited environment, the explosion-proof locomotive exhaust gas purification device is easy to install and the entire purification device is relatively small in size.

[0035] The exhaust pipe is made of tight stainless steel metal pipe. The exhaust pipe 1 is designed in a bend shape, which can make the most of the limited space. The intake pipe 2 is used to connect to the exhaust pipe of the explosion-proof locomotive, while the exhaust port 3 is used to discharge the purified exhaust gas.

[0036] The connecting pipe 42 is welded between the exhaust pipe 1 and the air inlet 2 to cool the high temperature of the explosion-proof vehicle exhaust. The connecting plate 44 is staggered and welded to the inner wall of the vent pipe 43. The intercepting plate 44 can increase the time and distance that the explosion-proof vehicle exhaust flows inside the vent pipe 43, thereby enhancing the heat exchange efficiency. The heat-conducting layer 45 is a thin layer of metal copper wrapped between the sleeve 41 and the vent pipe 43. Metal copper has excellent thermal conductivity and can be used to transfer the high temperature of the explosion-proof vehicle exhaust flowing inside the vent pipe 43 to the outside for heat exchange. The heat transfer rod 46 is also a hollow metal copper tube. The heat transfer rod 46 further transfers the temperature to the heat dissipation fins 47 arranged in multiple rows on the outside. Finally, the heat dissipation fins 47 diffuse the heat into the air to complete the heat dissipation requirements. In this way, the exhaust gas generated by the explosion-proof vehicle is fully and evenly cooled in a limited space, ensuring that the temperature of the exhaust gas is more conducive to subsequent purification treatment.

[0037] The mounting base 57 has grooves inside that match the threads on the outer wall of the mounting tube 54, so the disassembly tube 51 can be inserted laterally into the mounting bases 57 on both sides. Then, the disassembly tube 51 can be installed or disassembled by twisting it laterally. The support tube 53 is used to fix the disassembly tube 51 inside. The sealing ring 52 is made of natural rubber. After the two ends of the disassembly tube 51 are tightened on the mounting base 57, the sealing ring 52 will press against the end of the support tube 53 to achieve a tight seal. The adsorption layer 56 is made of multi-stage activated carbon material. The excellent adsorption effect of activated carbon is used to adsorb and remove impurities in the exhaust gas of the explosion-proof locomotive. The purification layer 55 is made of multi-stage fiber filter, which can further filter and purify the pollutants and dust inside the exhaust gas of the explosion-proof locomotive, ensuring that the pollution of the exhaust gas discharged later will be greatly reduced.

[0038] The fixing hoop 61 is a relatively thin, semi-circular metal hoop made of aluminum alloy that can be manually pried open. After being pried open, the fixing hoop 61 is fitted onto the outer wall of the exhaust pipe 1, the air inlet 2, and the air outlet 3. Then, bolts are used to tighten the fixing hoop 61 at the end of the overlapping block 62. The vertical beam 63 is made of metal steel pipe and welded to the outside of the fixing hoop 61. The other end of the vertical beam 63 can be installed near the exhaust gas emission position of the explosion-proof locomotive by bolts or other fixing parts.
