Description

Technical Field

[0001] This utility model relates to the field of thermal energy engineering technology, specifically a temperature-controlled hot air furnace and its anti-scalding and heat-insulating structure. Background Technology

[0002] Hot air furnaces are thermal power machinery that began to be widely used in my country in the late 1970s. They have become a replacement product for electric heat sources and traditional steam power heat sources in many industries. Hot air furnaces come in many varieties and series, and are classified into two types according to the method of coal feeding: hand-fired and machine-fired, and according to the type of fuel: coal, oil, gas, etc.

[0003] In today's market, temperature-controlled hot air furnaces and their associated anti-scalding and heat-insulating structures are typically designed with fixed installation, placing the anti-scalding and heat-insulating components in specific locations. However, this installation method may not provide sufficient anti-scalding protection for every part of the hot air furnace. When operators or maintenance personnel perform routine operations, maintenance, or repairs, they may accidentally come into contact with these high-temperature areas, resulting in burns.

[0004] Therefore, this utility model provides a temperature-controlled hot air furnace and its anti-scalding and heat-insulating structure to solve the above problems. Utility Model Content

[0006] This utility model provides a temperature-controlled hot air furnace and its anti-scalding and heat-insulating structure, aiming to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a heat insulation and anti-scalding structure for a temperature-controlled hot air furnace, the temperature-controlled hot air furnace including a hot air furnace body, a door rotatably mounted on the hot air furnace body, and a heat dissipation mechanism disposed inside the hot air furnace body for heat dissipation treatment of each position.

[0009] The heat dissipation mechanism includes a rack fixedly installed on the inner wall of the hot air furnace body, a first threaded rod rotatably installed inside the hot air furnace body, a servo motor disposed inside the hot air furnace body, a limiting rod fixedly installed inside the hot air furnace body, a lifting frame screwed onto the first threaded rod, a second threaded rod rotatably installed inside the lifting frame, a gear fixedly installed on the second threaded rod, a translation frame screwed onto the second threaded rod, and a fan disposed inside the translation frame.

[0010] As a preferred technical solution of this application, the output end of the servo motor is fixedly connected to the top end of the first threaded rod, the limiting rod passes through the lifting frame, and the gear meshes with the rack.

[0011] As a preferred technical solution of this application, a temperature-controlled hot air furnace is applied to the anti-scalding and heat-insulating structure described in any one of claims 1-2, including a placement rack, the placement rack being fixedly connected to the inside of the hot air furnace body, and a smoke exhaust pipe being fixedly connected to the top of the placement rack, the smoke exhaust pipe penetrating the hot air furnace body.

[0012] As a preferred technical solution of this application, a dual-axis motor is fixedly connected inside the translation frame, a rotating rod is fixedly connected to the output end of the dual-axis motor, and a first rotating plate is fixedly connected to the side surface of the rotating rod.

[0013] As a preferred technical solution of this application, a fixed rod is fixedly connected inside the translation frame, and a second rotating plate is fixedly connected to both ends of the fixed rod.

[0015] (III) Beneficial Effects

[0016] This utility model has a simple structure and is easy to use. Through the setting of the heat dissipation mechanism, after the servo motor is started, its output end drives the first threaded rod to rotate, so that the lifting frame can move up and down smoothly under the action of the limit device. At the same time, the meshing transmission of gear and rack ensures the rotation of the second threaded rod, which in turn pushes the translation frame to move horizontally. As the translation frame moves, the fan also moves accordingly, thereby effectively dissipating heat from various areas inside the hot air furnace, reducing the possibility of operators being burned and improving the safety of use.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a scalding-proof and heat-insulating structure for a temperature-controlled hot air furnace, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the temperature-controlled hot air furnace includes a hot air furnace body 1, a door 2 that is rotatably mounted on the hot air furnace body 1, and a heat dissipation mechanism disposed inside the hot air furnace body 1 for preventing scalding at each position.

[0027] The heat dissipation mechanism includes a rack 3 fixedly installed on the inner wall of the hot air furnace body 1, a first threaded rod 4 rotatably installed inside the hot air furnace body 1, a servo motor 5 installed inside the hot air furnace body 1, a limit rod 6 fixedly installed inside the hot air furnace body 1, a lifting frame 7 screwed onto the first threaded rod 4, a second threaded rod 8 rotatably installed inside the lifting frame 7, a gear 9 fixedly installed onto the second threaded rod 8, a translation frame 10 screwed onto the second threaded rod 8, and a fan 11 installed inside the translation frame 10.

[0028] The output end of the servo motor 5 is fixedly connected to the top end of the first threaded rod 4, the limit rod 6 passes through the lifting frame 7, and the gear 9 meshes with the rack 3.

[0029] When using the anti-scalding and heat-insulating structure of this temperature-controlled hot air furnace, first place the furnace body 1 in a suitable position, then start the servo motor 5. The output end of the servo motor 5 drives the first threaded rod 4 to rotate. Since the lifting frame 7 is screwed onto the first threaded rod 4 and is limited by the limiting rod 6, the lifting frame 7 can smoothly move up and down under the rotation of the first threaded rod 4. At the same time, the gear 9 meshes with the rack 3 as the lifting frame 7 moves up and down, thereby driving the second threaded rod 8 to rotate. Since the translation frame 10 is screwed onto the second threaded rod 8, the translation frame 10 rotates on the second threaded rod 8. The rotation of the 8 allows for translational movement. During translation, the translation frame 10 drives the internal fan 11 to move together, enabling the fan 11 to dissipate heat from different locations within the hot air furnace body 1. Furthermore, due to the meshing transmission between the gear 9 and the rack 3, the rotational speed of the second threaded rod 8 and the lifting speed of the lifting frame 7 can be matched, thus ensuring the smooth movement of the translation frame 10 and the fan 11. At the same time, the design of this heat dissipation mechanism can effectively prevent burns inside the hot air furnace body 1, avoiding burns caused by direct contact with high-temperature parts during operation.

[0030] This utility model provides a temperature-controlled hot air furnace, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a placement rack 19, which is fixedly connected to the inside of the hot blast furnace body 1. A flue gas pipe 20 is fixedly connected to the top of the placement rack 19, and the flue gas pipe 20 passes through the hot blast furnace body 1.

[0031] When in use, the flue gas generated inside the hot air furnace body 1 can be smoothly discharged through the exhaust pipe 20, preventing the flue gas from accumulating inside the hot air furnace body 1 and affecting the heat dissipation effect and working environment. At the same time, the placement rack 19 also provides stable support for other components inside the hot air furnace body 1, making the structure of the entire temperature-controlled hot air furnace more stable and reliable. This design not only improves the ease of use of the hot air furnace, but also ensures the safety and stability of the hot air furnace during operation.

[0032] Furthermore, to facilitate the use of this temperature-controlled hot air furnace, such as Figure 1 , Figure 2 and Figure 3 As shown, a fixed rod 15 is fixedly connected inside the translation frame 10. A second rotating plate 16 is fixedly connected to both ends of the fixed rod 15. A connecting rod 17 is rotatably connected to the end of the first rotating plate 14 away from the rotating rod 13.

[0033] The end of the connecting rod 17 away from the first rotating plate 14 is rotatably connected to one side of the second rotating plate 16. A mounting bracket 18 is fixedly connected between the two second rotating plates 16, and the fan 11 is fixedly installed inside the mounting bracket 18.

[0034] When the temperature-controlled hot air furnace is in use, the dual-axis motor 12 starts and drives the rotating rod 13 to rotate. Since the first rotating plate 14 is fixedly connected to the rotating rod 13, the first rotating plate 14 will rotate with the rotation of the rotating rod 13. At the same time, since the two ends of the connecting rod 17 are rotatably connected to the first rotating plate 14 and the second rotating plate 16 respectively, when the first rotating plate 14 rotates, it will drive the second rotating plate 16 to swing through the connecting rod 17, thereby enabling the mounting bracket 18 and the fan 11 to perform up-and-down reciprocating oscillating motion. This design not only increases the heat dissipation range of the fan 11, but also improves the heat dissipation efficiency, so that the temperature inside the hot air furnace body 1 can be reduced more evenly and quickly. The design of the temperature-controlled hot air furnace and its anti-scalding heat insulation structure improves the heat dissipation effect.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
