[0001] This utility model relates to the field of hot blast stoves, and in particular to a high-efficiency hot blast stove device. Background Technology
[0002] A high-efficiency hot blast stove is a device that can effectively convert fuel energy into hot air to provide thermal energy for various industrial processes or environments. However, existing high-efficiency hot blast stoves have some shortcomings in use. First, the energy utilization rate of existing high-efficiency hot blast stoves is low, which can easily lead to waste of resources, and some even emit polluting gases. Second, existing high-efficiency hot blast stoves lack safety protection measures. If used improperly, there may be safety hazards, or even explosions. Therefore, we propose a high-efficiency hot blast stove device. Utility Model Content
[0003] The main objective of this invention is to provide a high-efficiency hot blast furnace device that can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A high-efficiency hot air furnace device includes an outer shell, a heating device fixedly connected to the right side of the outer shell, four fixed columns fixedly connected to the right side of the heating device, and the other ends of the four fixed columns fixedly connected to a baffle. A ventilation device is fixedly connected to the left end of the outer shell, and support columns are fixedly connected to the two left corners of the bottom of the ventilation device. An explosion-proof shell is provided on the outer surface of the outer shell.
[0006] Preferably, the outer casing includes a heat exchange device, a heat exhaust pipe is fixedly connected to the bottom right side of the heat exchange device, the heating device includes a heat inlet pipe, a funnel is fixedly connected to the bottom of the heat inlet pipe, the ventilation device includes an air inlet, and a smoke exhaust pipe is fixedly connected to the left side of the heat exchange device.
[0007] By adopting the above technical solution: the heat exchange device is the core component of the hot air furnace. The high-temperature gas after combustion in the heating device is accompanied by soot, particles, dust and other impurities. Therefore, the heat is transferred through the heat exchange device to achieve clean and impurity-free hot air. The high-temperature gas after combustion in the heating device enters the heat exchange device from the heat inlet pipe, and the outside air enters the heat exchange device through the air inlet. Then the two gases circulate in the heat exchange device to transfer heat. Afterwards, the heated air is discharged from the heat exhaust pipe, while the cooled combustion gas is discharged from the device from the flue pipe.
[0008] Preferably, the heat exchange device includes a front pressure plate, a rear pressure plate is provided on the left side of the front pressure plate, six screws are symmetrically and slidably connected on both sides of the front pressure plate, nuts that cooperate with the screws are provided on both sides of the rear pressure plate, and several sets of heat exchange plates are fixedly connected between the front pressure plate and the rear pressure plate.
[0009] By adopting the above technical solution: the heat exchange device is framed by a front pressure plate and a rear pressure plate, with several heat exchange plates in the middle. The heat exchange plates are the core of the heat exchange device. The front pressure plate and the rear pressure plate are fixed by screws and nuts connected by threads.
[0010] Preferably, the heat exchange plate includes a front tube plate with downward-facing patterns and grooves on its surface, and the pattern on the back of the front tube plate is opposite to that on the front. A rear tube plate is provided on the left side of the front tube plate, with upward-facing patterns on its front and the pattern on the back of the rear tube plate being opposite to that on the front. Sealing plates are fixedly connected to the outer surfaces of both the front and rear tube plates. Each of the front and rear tube plates has four ventilation openings, which are vertically diagonally distributed, i.e., two on the left side of the front and two on the right side of the back, or two on the right side of the front and two on the left side of the back.
[0011] By adopting the above technical solution: a front tube sheet and a rear tube sheet are set together, and there are several sets inside the heat exchange device. The outer surfaces of the front tube sheet and the rear tube sheet are fixedly connected with sealing plates, which can play a sealing role, so that the device can be sealed. In the gap between the front tube sheet and the rear tube sheet, the gas will come out from one end of the vent and exit from the other end of the vent along the direction of the pattern. Only one type of gas will pass through, while the gaps on the left and right sides contain another type of gas. Moreover, the two types of gas will not come into contact with each other, so heat exchange can be carried out through the heat exchange plate.
[0012] Preferably, the explosion-proof shell has a U-shaped outer surface, and can be moved to the outer surface of the heating device by sliding, with the right side shell of the explosion-proof shell above the fixing column.
[0013] By adopting the above technical solution: the explosion-proof shell is a guarantee of device safety. It is usually made of sturdy metal and has a rectangular shape that can fully cover the heating device and heat exchange device. The explosion-proof shell can not only solve safety hazards, but also play a certain role in heat preservation, enabling the heating device to work more efficiently.

The high-temperature gas after combustion in the heating device enters the heat exchange device through the heat inlet pipe, and the outside air enters the heat exchange device through the air inlet. Then, the two gases circulate in the heat exchange device to transfer heat. Afterward, the heated air is discharged from the heat exhaust pipe, and the cooled combustion gas is discharged from the device through the flue pipe.

The pattern on the front is opposite to that on the back. A rear tube plate 1252 is provided on the left side of the front tube plate 1251. The front of the rear tube plate 1252 has an upward-facing pattern, and the pattern on the back of the rear tube plate 1252 is opposite to that on the front.

Both the front tube plate 1251 and the rear tube plate 1252 are provided with four ventilation openings 1253. The ventilation openings 1253 are vertically diagonally distributed, that is, two on the left side of the front and two on the right side of the back, or two on the right side of the front and two on the left side of the back.
[0028] Through the above scheme: the heat exchange device 12 is framed by a front pressure plate 121 and a rear pressure plate 122, with several heat exchange plates 125 in the middle. The heat exchange plates 125 are the core of the heat exchange device 12. The front pressure plate 121 and the rear pressure plate 122 are fixed by screws 124 and nuts 123 connected by threads. The front tube plate 1251 and the rear tube plate 1252 are a set, and there are several sets in the heat exchange device 12. The outer surfaces of the front tube plate 1251 and the rear tube plate 1252 are fixedly connected with sealing plates 1254. The sealing plates 1254 can play a sealing role, so that the device can be sealed. In the gap between the front tube plate 1251 and the rear tube plate 1252, the gas will come out from one end of the vent 1253 and exit from the other end of the vent 1253 along the direction of the pattern. Only one type of gas passes through, while the gaps on the left and right sides contain another type of gas.

[0030] Through the above scheme: the heat exchange device 12 is the core component of the hot air furnace.

Therefore, the heat is transferred through the heat exchange device 12 to achieve clean and impurity-free hot air. The high-temperature gas after combustion of the heating device 3 enters the heat exchange device 12 through the heat inlet pipe 31, and the outside air enters the heat exchange device 12 through the air inlet 41.

[0031] It should be noted that this utility model is a high-efficiency hot air furnace device. Firstly, the heat exchange device 12 is the core component of the hot air furnace. The high-temperature gas from combustion in the heating device 3 contains impurities such as soot, particles, and dust. Therefore, the heat exchange device 12 transfers heat to achieve clean, impurity-free hot air. The high-temperature gas from combustion in the heating device 3 enters the heat exchange device 12 through the heat inlet pipe 31, while outside air enters the heat exchange device 12 through the air inlet 41. The two gases then circulate within the heat exchange device 12 for heat transfer. The heated air is then discharged through the heat exhaust pipe 11, while the cooled combustion gas is discharged from the device through the flue pipe 42. The explosion-proof shell 2 is a safety feature of the device, typically made of sturdy metal, with a rectangular shape that fully covers the heating device 3 and the heat exchange device 12. The explosion-proof shell 2 not only eliminates safety hazards but also provides some insulation. The heat exchange device 12 consists of a front pressure plate 121 and a rear pressure plate 122. Plate 122 forms a frame with several heat exchange plates 125 in the middle. The heat exchange plates 125 are the core of the heat exchange device 12. The front pressure plate 121 and the rear pressure plate 122 are fixed by screws 124 and nuts 123 connected by threads. The front tube plate 1251 and the rear tube plate 1252 are a set, and there are several sets inside the heat exchange device 12. The outer surfaces of the front tube plate 1251 and the rear tube plate 1252 are fixedly connected with sealing plates 1254. The sealing plates 1254 can play a sealing role, so that the device can be sealed. In the gap between the front tube plate 1251 and the rear tube plate 1252, the gas will come out from one end of the vent 1253 and exit from the other end of the vent 1253 along the direction of the pattern. Only one type of gas passes through, while the gaps on the left and right are for another type of gas. The two types of gas will not come into contact with each other. In this way, heat exchange can be carried out through the heat exchange plates 125. The above components work together to make the device more convenient and efficient.
