[0022] Please see Figure 1 , Figure 2 , Figure 3 The pressure relief mechanism 8 includes a fixed base 81. The fixed base 81 is fixedly connected to the top of the tank body 1. An air outlet 82 is fixedly connected to the right end of the fixed base 81. A fixed rod 83 is fixedly connected inside the fixed base 81. A first spring 84 is provided on the outside of the fixed rod 83. One end of the first spring 84 is fixedly connected to the fixed base 81, and the other end of the first spring 84 is fixedly connected to the slider 85. By designing the first spring 84, the force of the first spring 84 can act on the slider 85. A sliding sleeve is provided on the outside of the fixed rod 83. The slider 85 is slidably connected to the fixed seat 81. The lower end of the slider 85 is fixedly connected to the connecting rod 86, which is slidably connected to the fixed seat 81. The lower end of the connecting rod 86 is fixedly connected to the plug 87, which is slidably connected to the fixed seat 81. A sealing ring 88 is fixedly sleeved on the outside of the plug 87, which is slidably connected to the fixed seat 81. By designing the sealing ring 88, the connection between the plug 87 and the fixed seat 81 can be sealed. By designing the pressure relief mechanism 8, the internal pressure of the tank 1 can be automatically relieved and vented.

[0023] Please see Figure 1 , Figure 4 The connecting mechanism 9 includes a connecting seat 91. The connecting seat 91 is fixedly connected to the top of the cover plate 13. The connecting seat 91 is slidably connected to the housing 7. A plug rod 92 is slidably sleeved inside the connecting seat 91. The plug rod 92 is slidably connected to the housing 7.

[0024] The specific implementation process of this utility model is as follows: During use, the exhaust gas enters the interior of the housing 7 through the inlet 12. Then, under the action of the filter plate 10, the impurities and particulate matter in the exhaust gas can be filtered and purified. The impurities and particulate matter can be filtered out to avoid the problem of impurities entering the heat conduction ring tube 4 and causing blockage. Moreover, there is no need to clean and maintain the heat conduction ring tube 4. Then, the exhaust gas enters the heat conduction ring tube 4 through the air inlet 6. When the exhaust gas enters the heat conduction ring tube 4, it can heat the heat conduction ring tube 4. The water can be heated through the contact between the heat conduction ring tube 4 and the water inside the tank 1, so as to realize the waste heat recovery of the exhaust gas during the water quenching process.

[0025] During the water heating process, when the internal pressure of the tank 1 is too high, gas will enter through the bottom of the fixed seat 81. The gas will push the plug 87 upward, and the plug 87 will drive the connecting rod 86 and the slider 85 upward. The slider 85 will slide along the fixed rod 83 and squeeze the first spring 84. When the sealing ring 88 separates from the inner wall of the fixed seat 81, the gas will enter the interior of the fixed seat 81 and finally be discharged through the air outlet 82. This achieves the purpose of automatically depressurizing the interior of the tank 1 and avoids the danger caused by excessive internal pressure of the tank 1.

[0026] When the filter plate 10 needs to be disassembled, simply pull the insertion rod 92 outward. The insertion rod 92 will cause the guide block 94 to slide along the guide rod 95. The guide block 94 will compress the second spring 96. At the same time, the insertion rod 92 will cause the magnetic block 97 to move horizontally. When the magnetic block 97 is attracted to the magnet 98, the insertion rod 92 can be pulled out from the slot 93. Then, the cover plate 13 can be moved up to remove the filter plate 10 from the inside of the housing 7, which makes it convenient to clean and maintain the filter plate 10 and impurities.
