Description

Technical Field

[0001] This utility model relates to an adjustable heating furnace, and more particularly to a silo space adjustable heating furnace applied in the field of heating equipment. Background Technology

[0002] A heating furnace is an industrial device that generates and transfers heat to bring materials (such as solids, liquids, and gases) to specific temperature requirements. It is widely used in metallurgy, chemical industry, machining, food processing, and other fields. Its core function is to raise the temperature of materials through a heating medium (such as hot air, flame, electric heating elements, etc.) to meet process requirements (such as drying, smelting, heat treatment, reaction heating, etc.).

[0003] Chinese patent CN218469556U discloses a tunnel-type heating furnace. By incorporating a dust removal mechanism, it facilitates timely treatment of the air inside the heating tunnel casing when a large amount of dust is generated during furnace operation. This prevents polluted air from escaping to the outside of the heating tunnel casing, ensuring a clean working environment and improving environmental friendliness. Two sets of circulating fans are symmetrically fixedly installed at the top of the heating tunnel casing. The dust removal mechanism is fixedly mounted on a conveyor support, and a dust cleaning mechanism is located within the dust removal mechanism. The dust removal mechanism includes a filter box, a suction fan, a suction pipe, a first filter plate, a second filter plate, and an exhaust pipe. The filter box is fixedly mounted on the conveyor support, and a dust removal chamber is provided inside the filter box. The suction fan is fixedly mounted at the top of the filter box.

[0004] Existing heating furnace equipment cannot flexibly adjust the heating space according to the size and quantity of materials. When heating small workpieces, an excessively large chamber space will cause heat to disperse and the temperature to rise slowly, which will not only waste energy, but also affect product quality due to uneven temperature field. When processing large or large quantities of materials, insufficient space will limit production capacity, requiring frequent start-ups and shutdowns of equipment or changes in furnace type, resulting in high operating costs. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that existing heating furnace equipment cannot flexibly adjust the heating space size according to the size and quantity of materials. When heating small workpieces, an excessively large chamber space will cause heat dispersion and slow heating, which not only wastes energy, but also affects product quality due to uneven temperature field. When processing large or large quantities of materials, insufficient space will limit production capacity, requiring frequent start-ups and shutdowns of the equipment or changes in furnace type, resulting in high operating costs.

[0006] To address the aforementioned problems, this utility model provides a heating furnace with adjustable chamber space, including a base. An electric conveyor belt is fixedly connected to the upper end of the base, and a heating furnace frame is installed at the upper end of the electric conveyor belt. A control chamber is fixedly connected to the upper end of the heating furnace frame. Multiple strip-shaped inner top grooves are formed on the upper inner wall of the heating furnace frame. A heat source conveying pipe is fixedly connected to the upper inner wall of the strip-shaped inner top grooves. Multiple hot air nozzles are fixedly connected to the lower end of the heat source conveying pipe. A partition contact block is provided between two adjacent strip-shaped inner top grooves. A side groove is formed on the right inner wall of the heating furnace frame. An electric push rod is fixedly connected to the inner side wall of the side groove. A sealed adjustable inner partition is connected to the output end of the electric push rod. A top contact roller is provided at the upper end of the sealed adjustable inner partition, and multiple horizontal bottom contact wheels are provided at the lower end of the sealed adjustable inner partition, with the multiple horizontal bottom contact wheels arranged horizontally and equidistantly.

[0007] In the aforementioned adjustable-space heating furnace, the equipment base provides stable support, and with adjustable sealed inner partitions, the silo space can be flexibly changed according to the material volume, significantly improving the equipment's adaptability to materials of different sizes and batches, and effectively avoiding the energy waste and uneven heating problems of fixed-space heating furnaces.

[0008] As a further improvement of this application, the sealed adjustable inner partition, the top contact roller shaft, and the multiple transverse bottom contact wheels are rotatably connected, and the multiple transverse bottom contact wheels are in contact with the electric conveyor belt.

[0009] As a further improvement of this application, the output end of the electric push rod is provided with a sliding inner block plate, and the sealed adjustable inner partition plate has a side groove at one end near the electric push rod.

[0010] As a further improvement of this application, springs are symmetrically fixedly connected to the upper and lower ends of the sliding inner block plate, and the springs are connected to the inner sidewall of the side groove.

[0011] As another improvement of this application, a protruding horizontal bar is fixedly connected to the lower end of the partition contact block, and the sealing adjustable inner partition corresponds to the protruding horizontal bar.

[0012] As a further improvement to this application, the top contact roller shaft and the protruding crossbar cooperate with each other, and multiple heat source delivery pipes are interconnected with the control chamber.

[0013] As a further improvement to this application, heat insulation curtains are provided at both the front and rear ends of the heating furnace frame, and the two heat insulation curtains are arranged symmetrically.

[0014] In summary, the equipment base in this solution provides stable support, and the adjustable and sealed inner partition allows for flexible changes in the hopper space according to the material volume. This significantly improves the equipment's adaptability to materials of different sizes and batches, effectively avoiding energy waste and uneven heating problems found in fixed-space heating furnaces. Furthermore, through the dual cooperation of the top contact roller shaft and protruding crossbar, and the horizontal bottom contact wheel and electric conveyor belt, combined with the adaptive adjustment of the springs, a tight seal is achieved at both the top and bottom ends, greatly reducing the risk of heat source leakage. This not only improves heat utilization and saves energy, but also ensures the stability and uniformity of heating temperature, thereby improving the quality of material heating.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-6 An adjustable-space heating furnace is shown, including a base 1. An electric conveyor belt 2 is fixedly connected to the upper end of the base 1. A heating furnace frame 3 is set at the upper end of the electric conveyor belt 2. A control chamber 16 is fixedly connected to the upper end of the heating furnace frame 3. Multiple strip-shaped inner top grooves 5 are opened on the upper inner wall of the heating furnace frame 3. A heat source conveying pipe 6 is fixedly connected to the upper inner wall of the strip-shaped inner top grooves 5. Multiple hot air nozzles 7 are fixedly connected to the lower end of the heat source conveying pipe 6. A partition contact block 15 is set between two adjacent strip-shaped inner top grooves 5. A side groove opening 17 is opened on the right inner wall of the heating furnace frame 3. An electric push rod 9 is fixedly connected to the inner side wall of the side groove opening 17. The output end of the electric push rod 9 is connected to a sealed adjustable inner partition 4. A top contact roller shaft 14 is set at the upper end of the sealed adjustable inner partition 4. Multiple horizontal bottom contact wheels 13 are set at the lower end of the sealed adjustable inner partition 4, and the multiple horizontal bottom contact wheels 13 are arranged horizontally at equal intervals.

[0027] Figures 1-6 The sealed adjustable inner partition 4, the top contact roller shaft 14, and multiple transverse bottom contact wheels 13 are rotatably connected. The multiple transverse bottom contact wheels 13 are in contact with the electric conveyor belt 2. The output end of the electric push rod 9 is provided with a sliding inner block plate 12. The sealed adjustable inner partition 4 has a side groove 10 at one end near the electric push rod 9. The upper and lower ends of the sliding inner block plate 12 are symmetrically fixedly connected with springs 11, and the springs 11 are connected to the inner side wall of the side groove 10. The lower end of the partition contact block 15 is fixedly connected with a protruding horizontal bar 8. The sealed adjustable inner partition 4 and the protruding horizontal bar 8 correspond to each other. The top contact roller shaft 14 and the protruding horizontal bar 8 cooperate with each other. Multiple heat source conveying pipes 6 are all connected to the control chamber 16.

[0028] Figures 1-7The adjustable-space heating furnace is shown to be stably supported by the equipment base 1, laying the foundation for overall operation. During operation, the electric conveyor belt 2 is used to transport materials into the heating furnace frame 3, while the control chamber 16 is responsible for controlling and adjusting the operation of the entire heating system. When the space inside the furnace needs to be adjusted, the control chamber 16 sends a command to the electric push rod 9, which is located in the side groove 17 on the right inner wall of the heating furnace frame 3. The sealed adjustable inner partition 4 connected to its output end moves under the extension and retraction of the electric push rod 9, thereby changing the size of the internal space inside the heating furnace to accommodate materials of different volumes. In the initial state, the horizontal bottom contact wheel 13 is in slight contact with the running electric conveyor belt 2. When the electric push rod 9 pushes the sealed adjustable inner partition 4 to move and adjust the space inside the furnace, the top contact roller shaft 14 at its upper end does not contact the protruding horizontal bar 8 at the lower end of the partition contact block 15 at first. During material conveying, the electric push rod 9 drives the adjustable sealed inner partition 4 to push forward slightly, so that the top contact roller shaft 14 fits against the protruding crossbar 8, forming an upper limit guide. At the same time, the adjustable sealed inner partition 4 is pushed by the thrust to compress the spring 11 in the side groove 10. The elastic force generated by the compression of the spring 11 pushes the adjustable sealed inner partition 4 downward, so that the transverse bottom contact wheel 13 fits tightly against the surface of the electric conveyor belt 2. While maintaining the flexibility of rotation, the transverse bottom contact wheel 13 blocks heat leakage from the bottom. The cooperation between the top contact roller shaft 14 and the protruding crossbar 8 restricts the movement of the partition from the top and reduces heat overflow. The double sealing structure effectively reduces the risk of heat source leakage and ensures the stability of the internal temperature of the heating furnace and the efficient use of heat. During the heating process, the control chamber 16 controls the heat source to spray hot air into the heating furnace through the heat source conveying pipe 6 and the hot air nozzle 7 in the strip-shaped inner top groove 5.

[0029] Second implementation method:

[0030] Figure 1 An adjustable heating furnace with adjustable chamber space is shown. Heat insulation curtains 18 are provided at both the front and rear ends of the heating furnace frame 3. The two heat insulation curtains 18 are symmetrically arranged. The heat insulation curtains 18 at both the front and rear ends of the heating furnace frame 3 can reduce heat loss, maintain stable internal temperature, and ensure that the material is heated evenly under the set temperature environment.

[0031] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
