Technical Field
[0001] This utility model relates to the field of hot blast stoves, and in particular to a hot blast stove with complete combustion. Background Technology
[0002] Hot blast stoves are thermal power machines that began to be widely used in my country in the late 1970s. They have become a replacement for electric heat sources and traditional steam power sources in many industries. Hot blast stoves come in many varieties and series, and are classified into hand-fired and machine-fired types according to the method of coal feeding, and into coal, oil, and gas stoves according to the type of fuel.
[0003] Most hot air furnaces currently in use have a simple structure, where combustible materials burn in the combustion chamber and combustible objects burn freely in the combustion chamber. They are not equipped with corresponding oxygen supply devices, which leads to insufficient combustion of combustible objects due to insufficient oxygen intake. This results in a lot of resource waste, low heat conversion efficiency, inconvenience in use, and poor usability. Utility Model Content

Figure 1 For clarity of view and to show the connection between the second blower 26 and oxygen tank 20 and the base plate 37, it should be noted that in actual use, the second blower 26 and oxygen tank 20 are connected to the base plate 37. This is hereby explained.
[0025] The main air inlet pipe 22 is also connected to an air supply pipe 24, which is connected to a connecting ring pipe 7. The connecting ring pipe 7 can be connected to the insulation box 1. The insulation box 1 is connected to a sealing ring 9, the inner ring of which is connected to the side wall of the combustion chamber. The sealing ring 9 is also connected to a partition plate 36. Figure 4 As shown, the partition plate 36 is provided with several groups, the connecting ring pipe 7 is connected to the air inlet pipe 8, the air inlet pipe 8 is provided with several groups, the several groups of air inlet pipe 8 are all connected to the sealing ring 9, the several groups of air inlet pipe 8 are evenly arranged along the sealing ring 9, the heat preservation box 1 is connected to the air outlet pipe 14 and the air outlet ring pipe 15, the air outlet pipe 14 is provided with several groups, the several groups of air outlet pipe 14 are connected to the air outlet ring pipe 15, the air outlet ring pipe 15 is connected to the hot air pipe 17, the second oxygen supply pipe 28 is connected to the second switch 27, and the oxygen supply pipe 4 is connected to the first switch 23.
[0026] The heat preservation box 1 is connected to a mounting bracket 16, the mounting bracket 16 is connected to a filter tube 32, the filter tube 32 is connected to an exhaust pipe 29, the filter tube 32 is connected to an activated carbon plate 34 and a filter plate 35, the mounting bracket 16 is connected to an exhaust pipe 33, the filter tube 32 is threadedly connected to the mounting bracket 16, the filter tube 32 is connected to a flexible hose 31, the flexible hose 31 is connected to a clamping tube 30, and the clamping tube 30 can be slidably connected to the exhaust pipe 29.

[0028] The specific implementation process is as follows:
[0029] During operation, combustible materials are introduced into the first chamber 11 to burn and heat the combustion chamber. Cold air from outside is drawn into the main air intake pipe 22 by the first fan 21. The first switch 23, the second switch 27, and the second fan 26 are opened. The cold air enters the main air intake pipe 22 and flows to the air supply pipe 24 and the oxygen inlet pipe 4, respectively. Under the action of the second fan 26, oxygen flows from the oxygen tank 20 along the first oxygen supply pipe 25 and the second oxygen supply pipe 28 into the oxygen inlet pipe 4, where it combines with the air. The oxygen-rich air flows along the oxygen inlet pipe 4 and the connecting pipe 10, and then exits through the oxygen supply bend 18 into the first chamber 11 and the second chamber 13, increasing the oxygen content for combustion. The flue gas generated from the combustion of materials in the first chamber 11 is discharged through the smoke guide pipe 19 into the second chamber 13 for further combustion. The air is discharged from the exhaust pipe 29, filtered by the filter plate 35 and activated carbon plate 34 in the filter pipe 32, and then discharged through the exhaust pipe 33. A portion of the cold air flows along the air supply pipe 24 and the connecting ring pipe 7, and then enters the space between the insulation box 1, the combustion box and the partition plate 36 from the air inlet pipe 8. The cold air is heated by the hot combustion box here and then discharged from the air outlet pipe 14 into the air outlet ring pipe 15. The heated air can then be discharged from the hot air pipe 17. During this period, the oxygen supply and the amount of air in the air inlet pipe can be adjusted by controlling the first switch 23 and the second switch 27. When the filter pipe 32 needs to be replaced, slide the clamp 30 upwards, and then the filter pipe 32 can be twisted to complete the disassembly. The installation is done in reverse. When in use, the support foot 38 should be grounded. When it needs to be moved, the cylinder 6 can drive the mounting plate 2 and the universal wheel 5 to be grounded.
[0030] In this technical solution, the main air inlet pipe 22 is connected to the oxygen inlet pipe 4 and the air supply pipe. The first fan 21 drives cold air into the insulation box 1 for heating, while the oxygen inlet pipe 4 accelerates the rate at which outside air enters the combustion chamber, increasing the oxygen intake rate. The oxygen tank 20 also increases the oxygen content of the air entering the combustion chamber, thus ensuring complete combustion of the materials within the combustion chamber, rationally utilizing resources, improving heat conversion efficiency, and greatly enhancing practicality. The second chamber 13 allows for secondary combustion of the flue gas, reducing pollution while further improving heat conversion efficiency. Two sets of oxygen supply bends 18 can further reduce air pollution. The rate at which air enters the combustion chamber is controlled to prevent air from blowing the flame and affecting combustion; the exhaust gas can be filtered through the filter tube 32, ensuring that it is filtered before being discharged, thus protecting the environment; the cylinder 6 can drive the casters 5 to move up and down, allowing the device to be placed stably for use while facilitating movement, and also preventing damage to the casters 5 due to long-term load; the first switch 23 and the second switch 27 can control the rate of air entering the combustion chamber and the oxygen content, facilitating the rational planning of oxygen and other resources and improving the practicality of the device; the hose 31 and the clamp 30 facilitate the disassembly and replacement of the filter tube 32.
