[0002] The gas trolley furnace with waste heat recovery function is an efficient and energy-saving industrial heating equipment. It can reuse the waste heat generated by the furnace body and is equipped with an efficient gas burner to ensure high combustion efficiency and high thermal energy utilization. It usually adopts advanced combustion technologies, such as premixed combustion, nozzle design optimization, etc. to improve combustion efficiency and reduce emissions. The waste heat recovered by the heat exchanger is transferred to air or water for heating or preheating the medium required in other process steps. The recovered waste heat is transported to the place where heating is required through the pipeline system. Through the above design, the gas trolley furnace with waste heat recovery function can effectively utilize the waste heat generated by the furnace body.

[0003] In the specific use of gas trolley furnaces, the existing gas trolley furnaces adopt a trolley structure with a movable furnace bottom. The trolley and the furnace body are two independent components. When the furnace door is opened, a large amount of heat will be generated and dissipated from around the furnace mouth. The temperature in the furnace will decrease. When in use, the gas usage of the trolley furnace will increase, resulting in a waste of resources and inconvenience for the operator to use.

The circulation mechanism 1 is a mechanism that can recycle the heat generated inside the furnace body 12. The circulation mechanism 1 includes an installation box 13, which is arranged on one side of the furnace body 12. A recovery box 17 is arranged on the top of the furnace body 12. An exhaust pump 16 is arranged between the recovery box 17 and the installation box 13. A first filter plate 15 is arranged inside the installation box 13. A circulation pump 19 is arranged on the top of the recovery box 17. They cooperate with each other, so that when the operator needs to recycle the heat generated inside the furnace body 12, first, when the furnace door 2 is closed, the heat in the furnace will enter the inside of the installation box 13, and then the operator can start the vacuum pump 16 to extract the heat inside the installation box 13. When the heat is extracted, it passes through the first filter plate 15, the installation pipe 22 and the fixed pipe 27 and enters the recovery box 17. The first filter plate 15 filters impurities such as dust mixed in the hot air, and the recovery box 17 collects the hot air. Since an insulation board is arranged inside the recovery box 17, the heat in the hot air in the recovery box 17 can be effectively prevented from dissipating to the outside of the recovery box 17, so that the heat can be collected.

[0029] Reference Figure 1-Figure 6In a preferred embodiment, the second filter plate 18 is arranged inside the recovery box 17, and a temperature sensor 24 is arranged on one side of the recovery box 17. By setting the temperature sensor 24, the inside of the recovery box 17 can be monitored. A groove 14 is opened on one side of the inner cavity of the furnace body 12, and the groove 14 is connected to the installation box 13. A mounting pipe 22 is inserted through the top of the installation box 13, and one end of the mounting pipe 22 is arranged at the top of the vacuum pump 16. A fixed pipe 27 is inserted through one side of the recovery box 17, and one end of the fixed pipe 27 is arranged at the bottom of the vacuum pump 16. A mounting door 21 is arranged on one side of the installation box 13. By setting the mounting door 21, the operator can open the mounting door 21 after the first filter plate 15 has been used for a long time to clean the first filter plate 15. The height of the mounting door 21 is higher than that of the first filter plate 1 5, through the mutual cooperation of the furnace door 2, the furnace body 12, the circulation pump 19, the recovery box 17 and the second filter plate 18, when the operator opens the furnace door 2 and pushes out the trolley, the hot air will dissipate from the furnace body 12, and the temperature inside the furnace body 12 will decrease. After taking and placing the materials inside the trolley, the operator can push the trolley into the furnace body 12. At this time, the operator can start the circulation pump 19 to extract the hot air inside the recovery box 17, and enter the furnace body 12 through the exhaust pipe 26, the second filter plate 18 and the air inlet pipe 23, so as to supplement the heat in the furnace body 12, and the dust and other impurities mixed in the hot air can be filtered for the second time through the second filter plate 18, so as to avoid the temperature of the furnace body 12 from decreasing with the opening of the furnace door 2, reduce the gas usage, and do not cause waste of resources, which is convenient for the operator to use.

[0030] Reference Figure 1-Figure 6 In a preferred embodiment, an exhaust pipe 26 is inserted into the top of the recovery box 17, one end of the exhaust pipe 26 is arranged on one side of the circulation pump 19, and an air intake pipe 23 is arranged on the other side of the circulation pump 19. The air intake pipe 23 is inserted into the top of the furnace body 12, and a furnace door 2 is arranged at the front of the furnace body 12. By setting the furnace door 2, it is convenient for the operator to push out the trolley. The trolley is part of the gas trolley furnace (not shown in the figure). An insulation board is arranged inside the recovery box 17. By setting the insulation board, the temperature inside the recovery box 17 can be increased.

[0031] Specifically, the working process or working principle of the gas trolley furnace with waste heat recovery function is as follows: in the specific use of the gas trolley furnace, the existing gas trolley furnace adopts a trolley structure with a movable furnace bottom. The trolley and the furnace body 12 are two independent components. When the furnace door 2 is opened, a large amount of heat will be generated and dissipated from the surroundings of the furnace mouth. The temperature in the furnace will decrease. When in use, the gas usage of the trolley furnace will increase, thereby causing a waste of resources and being inconvenient for the operator to use. Therefore, the present technical solution can solve the above problems. When the operator needs to recycle the heat generated inside the furnace body 12, first, when the furnace door 2 is closed, the heat in the furnace will enter the interior of the installation box 13. Then the operator can start the vacuum pump 16 to extract the heat inside the installation box 13. When extracting, the heat passes through the first filter plate 15, the installation pipe 22 and the fixed pipe 27 into the recovery box 17. The first filter plate 15 The hot air is filtered out by the recycling box 17, and the dust and other impurities are collected by the recycling box 17. Since the insulation board is arranged inside the recycling box 17, the heat in the hot air in the recycling box 17 can be effectively prevented from being dissipated to the outside of the recycling box 17. When the operator opens the furnace door 2 and pushes out the trolley, the hot air is dissipated out of the furnace body 12, and the temperature inside the furnace body 12 will decrease. After taking and placing the materials inside the trolley, the operator can push the trolley into the furnace body 12. At this time, the operator can start the circulation pump 19 to extract the hot air inside the recycling box 17, and enter the furnace body 12 through the exhaust pipe 26, the second filter plate 18 and the air inlet pipe 23, so that the heat in the furnace body 12 can be supplemented, and the dust and other impurities mixed in the hot air can be filtered for the second time through the second filter plate 18, so as to avoid the temperature of the furnace body 12 from decreasing as the furnace door 2 is opened, reduce the gas usage, and will not cause waste of resources, which is convenient for the operator to use, and all processes are ended here.

[0032] It should be noted that the vacuum pump 16, the circulation pump 19 and the temperature sensor 24 are all electrically connected to the external power supply and are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
