[0002] A hot air furnace is a device that uses combustion to release heat to perform heating and heat preservation functions. After combustion under certain conditions, it transfers heat in the form of steam or hot air. It can heat and transfer energy to machines or materials, process materials or perform post-processing sintering or roasting, and absorb the release of heavy metals in flue gas.

[0003] For example, the patent with publication number CN203053016U (a hot air furnace device) includes an outer frame and an inner furnace body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 An embodiment of this utility model provides a multi-functional hot air furnace, including a combustion chamber body 5. A burner interface 12 is fixedly installed on the upper side of one side of the combustion chamber body 5. A burner 11 is fixedly installed on one side of the burner interface 12 of the combustion chamber body 5. A second feed box 9 is fixedly installed on the lower side of one side of the combustion chamber body 5. One end of the second feed box 9 extends into the interior of the combustion chamber body 5. A first feed box 8 is provided above the second feed box 9. Both the first feed box 8 and the second feed box 9 are provided with a screw mechanism 17. The screw mechanism 17 includes a rod body 18 and a spiral blade 19. The spiral blade 19 is fixedly installed on the outside of the rod body 18. Both the first feed box 8 and the second feed box 9 are provided with a drive motor for the internal screw mechanism 17.

[0023] In use, the burner 11, feed box 8, and feed box 9 can be equipped with natural gas, biomass pellets, and coal to meet customer needs. The feed box 8 and feed box 9 can form a segmented feeding system. During feeding, the screw mechanism 17 in feed box 8 rotates at a slow speed, while the screw mechanism 17 in feed box 9 rotates at a fast speed to prevent backfire of the burning material and increase safety.

[0024] Furthermore, an insulation layer 6 is provided on the upper part of the combustion chamber body 5, and a refractory brick layer 13 is provided on the lower part of the combustion chamber body 5.

[0025] The insulation layer 6 can effectively reduce heat loss, improve thermal energy utilization efficiency, and reduce energy consumption, while the refractory brick layer 13 enhances the high temperature resistance of the combustion chamber body 5, extends the service life of the equipment, and ensures the stability and safety of the combustion process.

[0026] Furthermore, a blower 10 is fixedly installed on one side of the combustion chamber body 5 along the lower part of the feed box 2 9. The output end of the blower 10 is connected to the combustion chamber body 5. A porous honeycomb furnace plate 14 is fixedly installed inside the combustion chamber body 5 along the lower part of the feed box 2 9.

[0027] The blower 10 provides ample combustion air, which is evenly distributed into the combustion chamber through the porous honeycomb furnace plate 14, promoting complete combustion of fuel, improving combustion efficiency and heat output, and reducing the emission of harmful substances, which is beneficial to environmental protection.

[0028] Furthermore, a maintenance bracket 4 is fixedly installed on the upper side of one side of the combustion chamber body 5. The maintenance bracket 4 is located above the burner 11. An operating platform 7 is set in the middle of one side of the combustion chamber body 5. A gantry frame 1 is set on one side of the operating platform 7.

[0029] The maintenance bracket 4 facilitates the maintenance and repair of the burner 11, ensuring the long-term stable operation of the equipment. The operating platform 7 provides a working environment for the operators. The gantry 1 not only serves as a structural support but also provides an installation foundation for the feeding system. The overall design optimizes the operability and maintainability of the equipment.

[0030] Furthermore, the gantry frame 1 is equipped with a hopper 3 inside, and a feeding pipe 15 is fixedly installed below the hopper 3. The lower end of the feeding pipe 15 is fixedly connected to the feed box 8. A dropping pipe 16 is fixedly installed below one end of the feed box 8, and the lower end of the dropping pipe 16 is fixedly connected to the feed box 9.

[0031] It can automate material feeding, reduce reliance on manual operation, improve feeding efficiency and accuracy, and reduce material loss during the conveying process, thus ensuring the continuous and stable operation and efficient output of the hot air furnace.

[0032] Furthermore, an electric hoist 2 is installed above the inside of the gantry frame 1.

[0033] Electric hoists 2 provide a convenient means for handling materials used for combustion and for installing structures. When replacing or repairing components inside the combustion chamber, they can greatly improve work efficiency, reduce labor costs, and also enhance the safety and operability of the equipment.

[0034] Working principle: During use, fuels such as natural gas, biomass pellets, or coal are introduced through the burner 11. Segmented feeding is achieved using screw mechanisms 17 within feed boxes 8 and 9. The screw mechanism 17 in feed box 8 rotates at a slower speed, while the screw mechanism 17 in feed box 9 rotates at a faster speed to prevent backfire and increase safety. After the fuel enters the combustion chamber body 5, the blower 10 provides sufficient combustion air, which is evenly distributed into the combustion chamber through the porous honeycomb furnace plate 14, promoting combustion. The complete combustion of the material improves combustion efficiency and heat output. At the same time, the insulation layer 6 inside the combustion chamber body 5 effectively reduces heat loss and improves heat utilization efficiency, while the refractory brick layer 13 enhances high-temperature resistance and extends the service life of the equipment. In addition, the hopper 3, feeding pipe 15, feeding box 1 8, dropping pipe 16 and feeding box 2 9 constitute an automated feeding structure, reducing manual operation and improving feeding efficiency and accuracy. The electric hoist 2 provides convenient material handling and structural installation methods, optimizing equipment maintenance and work efficiency.
