Technical Field

[0001] This utility model relates to the field of hot blast stove technology, specifically a novel six-hole air distribution structure for hot blast stoves. Background Technology

[0002] A hot air furnace is a device that generates high-temperature hot air by burning fuel. It is widely used in industrial production processes such as heating, drying, and baking. It transfers the heat generated by fuel combustion to the air through the combustion chamber, heating the air to the required temperature. The hot air is then transported to the working area by a fan to meet the heat energy requirements of different production processes. Hot air furnaces have the advantages of high efficiency, energy saving, and controllable temperature, and can provide a stable heat source for a variety of industrial applications. Existing technologies, by setting a six-hole air distribution structure, can optimize air distribution during combustion, improve combustion efficiency and temperature uniformity. However, if the air input ratio cannot be controlled according to actual needs, problems will arise. If the orifice diameter is too large, the air flow rate will be reduced, affecting the stability of the flame. If the orifice diameter is too small, the thermal efficiency will be affected. Therefore, a new six-hole air distribution structure for hot blast stoves is proposed to address the above problems. Utility Model Content

[0016] Please see Figures 1-8 This utility model provides a technical solution: A novel six-hole air distribution structure for a hot blast stove includes a hot blast stove assembly 1. A pressing assembly 3 is threadedly connected to the front end of the hot blast stove assembly 1, and an air volume regulating assembly 2 is pressed to the rear end of the pressing assembly 3. The hot blast stove assembly 1 includes a hot blast stove body 11, an end plate 12 is fixedly connected to the inner side of the hot blast stove body 11, a threaded groove 16 is opened near the front end of the hot blast stove body 11, an assembly groove 17 is opened on the inner side of the end plate 12, and a compression spring 18 is fixedly connected to the rear end of the assembly groove 17 of the end plate 12. The air volume regulating assembly 2 includes a pressure plate 21, a ceramic sealing gasket 22 is fixedly connected to the inner side of the pressure plate 21 near the rear end, and both the pressure plate 21 and the ceramic sealing gasket 22 have adjusting holes 23 on their inner sides. The pressing assembly 3 includes a collar 31, a hollow cavity 32 is opened on the inner side of the collar 31, and the collar 31 has external threads 33.

[0017] As a further implementation of this solution, an air distribution hole 13 is provided on the inner side of the end plate 12, and an end cover 14 is fixedly connected to the end plate 12 near the middle. A burner 15 is fixedly connected to the inner side of the end cover 14. Through the above arrangement, this structural design allows air to enter the combustion chamber through the air distribution hole 13. The fixed connection between the end cover 14 and the burner 15 enhances the stability of the structure, ensures the uniformity and stability of air flow, and thus improves combustion efficiency. As a further implementation of this solution, the outer side of the pressure plate 21 is attached to the inner side of the hot air furnace body 11, the center of the pressure plate 21 and the center of the end plate 12 are on the same horizontal line, and the front end of the pressure plate 21 is fixedly connected to the first operating handle 24. Through the above settings, this design enables the pressure plate 21 to move stably within the hot air furnace body 11. The angle of the pressure plate 21 can be precisely adjusted by operating the first operating handle 24, thereby achieving precise control of the air input. As a further implementation of this solution, the rear end of the pressure plate 21 is attached to the front end of the compression spring 18, the ceramic sealing gasket 22 is away from the compression spring 18, and the rear end of the ceramic sealing gasket 22 is attached to the front end of the end plate 12. With the above arrangement, this layout allows the pressure plate 21 to move away from the end plate 12 by the elastic force of the compression spring 18 when it moves. At the same time, the tight fit between the ceramic sealing gasket 22 and the end plate 12 ensures the airflow sealing, avoids air leakage, and improves thermal efficiency. As a further implementation of this solution, the burner 15 is embedded in the mating groove 25 opened in the pressure plate 21. A gap is provided between the inner side of the mating groove 25 opened in the pressure plate 21 and the outer side of the end cover 14. Through the above setting, this design allows the burner 15 to move freely in the mating groove 25, while the existence of the gap ensures that air can pass through smoothly. As a further implementation of this solution, the external thread 33 of the collar 31 is threadedly connected to the threaded groove 16 of the hot blast stove body 11. The hollow cavity 32 of the collar 31 is located outside the multiple adjustment holes 23. The rear end of the collar 31 presses against the front end of the pressure plate 21. The front end of the collar 31 is fixedly connected to a second operating handle 34. Through the above settings, the collar 31 can move back and forth inside the hot blast stove body 11, thereby applying pressure to or releasing pressure on the pressure plate 21. The position design of the hollow cavity 32 enables the collar 31 to effectively press and adjust the adjustment holes 23, thereby achieving flexible control of the air input and improving combustion stability.

[0018] Working process: During use, the output end of the burner 15 is fixedly connected to a connecting pipe, and the other end of the connecting pipe passes through the end cover 14 and is located inside the hot blast stove body 11. Six evenly distributed air distribution holes 13 are opened on the end plate 12. The air distribution holes 13 are aligned with the adjustment holes 23 and communicate with the interior of the hot blast stove body 11. Through the cooperation of the end plate 12, burner 15, connecting pipe, end cover 14 and air distribution holes 13, the hot blast stove body 11 is equipped with a six-hole air distribution structure, which improves the oxygen contact rate of the hot blast stove body 11 and improves the combustion efficiency and combustion effect. When the air injection ratio needs to be adjusted, firstly, the second operation is performed to rotate the collar 31 by operating 34. Since the collar 31 is threadedly connected to the threaded groove 16 of the hot air furnace body 11 through the external thread 33, the collar 31 will move forward. At this time, under the elastic force of the compression spring 18, it will push the pressure plate 21 forward, so that the ceramic sealing gasket 22 is in contact with the front end of the end plate 12. After the collar 31 has moved forward by one centimeter, the first operation can then be performed normally to rotate the pressure plate 21 by operating 24. The rotation of the pressure plate 21 in the hot air furnace... The inside of the furnace body 11 does not contact the threaded groove 16. The pressure plate 21 drives the ceramic sealing gasket 22 to rotate. After rotating a certain angle, the collar 31 is rotated by the second operation handle 34. During this process, the pressure plate 21 needs to be fixed by holding the first operation handle 24 to prevent the friction of the collar 31 from driving the pressure plate 21 to rotate. After the rear end of the ceramic sealing gasket 22 is tightly attached to the front end of the end plate 12, the adjustment hole 23 opened on the pressure plate 21 is partially aligned with the air distribution hole 13, thereby realizing the amount of air flowing through the air distribution hole 13. Based on the above principles, the device can control the amount of air passing through the air distribution hole 13 according to the needs of the combustion process, thereby controlling the air input ratio inside the hot air furnace body 11, ensuring flame stability, and improving thermal efficiency.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
