Description

Technical Field

[0001] This utility model relates to the field of hot air supply technology, and in particular to a hot air supply device. Background Technology

[0002] A hot gas supply device is a device that generates hot gas flow through fuel combustion, electrical energy conversion or other energy conversion methods, and delivers it to a specific space or equipment to meet the needs of heating, drying, and warming. The core principle of a hot gas supply device is to generate high-temperature gas through energy conversion, and then deliver the hot gas to the target area through components such as fans and pipes.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When existing hot air supply equipment supplies hot air, if the pipes or containers continuously expand (such as steam boilers or pressurized hot air pipes), and the pressure is not released or the heat source is cut off in time, the internal pressure will rise sharply, exceeding the equipment's design pressure limit. This may cause the equipment body to crack, the pipes to burst, or even explode. Hot air leakage will cause the ambient temperature to rise sharply, which may burn people or ignite nearby combustibles. Pipes and connectors may deform, and the continuously expanding hot air will cause metal pipes or containers to fatigue due to repeated thermal stress (such as pipe bends and welds), leading to cracks, deformation, or breakage. Utility Model Content

[0004] To solve the above problems, this utility model provides a hot gas supply device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a hot air supply device includes a base plate, a support frame is fixedly provided on the upper surface of the base plate, a through groove is fixedly provided at the middle position of the top of the support frame and an electromagnetic plate is fixedly provided on its inner wall, an elastic switch is provided at the middle of one side of the electromagnetic plate, a horizontal plate is fixedly provided at the end of the elastic switch away from the electromagnetic plate, a slider is fixedly provided at one end of the horizontal plate, a moving rod is fixedly inserted into the middle of the slider, a socket plate is fixedly provided at the bottom of the moving rod, an arc-shaped rod is fixedly provided at the middle position of the top of the socket plate, a limiting slide plate is fixedly provided at the top of the arc-shaped rod, and the outer side of the top of the limiting slide plate is slidably connected to the groove on the lower surface of the base plate.

[0006] A solenoid valve is fixedly installed on one side of the top of the solenoid plate and electrically connected to it. A pipe is fixedly inserted into the middle of the solenoid valve. A union joint is fixedly installed at the top of the pipe. A collar is sleeved on the outer side of the middle of the union joint. A support rod is fixedly installed on the outer side of the collar. The bottom of the support rod is fixedly installed on the top of the support frame.

[0007] By adopting the above technical solutions, timely cutting off the supply of hot gas acts as a "stop valve" for the safe operation of hot gas equipment, avoiding excessive supply of hot gas, and achieving long-term benefits through equipment protection, process stability, and cost control.

[0008] Furthermore, the movable rod is set in an "L" shape, with the bottom of the movable rod being laterally away from the edge of the base plate. The outer circumferential surface of the movable rod near the top is slidably fitted with a limiting rectangular plate. One end of the limiting rectangular plate is fixedly set in the middle of one side of the base plate, and a groove is provided in the middle of the limiting rectangular plate.

[0009] By adopting the above technical solution, the "L"-shaped moving rod avoids movement conflict with the base plate, and the limiting rectangular plate restricts the movement trajectory of the moving rod to prevent the moving rod from deviating during movement.

[0010] Furthermore, the socket plate is wavy, and there are two socket plates, which are symmetrically arranged at the bottom of the base plate.

[0011] By adopting the above technical solution, the corrugated socket plate can more easily connect heating pipes of different specifications, increasing its ability to adapt to the environment.

[0012] Furthermore, a movable plate is fixedly installed at one end of the limiting slide plate, and the end of the movable plate away from the limiting slide plate is fixedly sleeved on the outer side of the middle of the movable rod. The limiting slide plate is set in a "T" shape.

[0013] By adopting the above technical solution, and by setting the movable plate to move along the movable rod, it is ensured that the limiting slide plate at one end can slide smoothly.

[0014] Furthermore, a connector is fixedly installed at the bottom of the solenoid valve. The bottom of the connector is tapered. Electromagnetic plates are installed on both sides of the solenoid valve. Flexible switches are inserted into the outer sides of the two electromagnetic plates. The connector passes through the middle of the base plate.

[0015] By adopting the above technical solution, the conical joint can be easily and tightly connected to the heating pipeline, and the power supply demand of the electromagnetic plate to the inner electromagnetic valve can be controlled by the flexible switch.

[0016] Furthermore, two identical vertical plates are provided on both sides of the lower surface of the base plate. A horizontal shaft is fixedly installed on the inner side of the vertical plate. The horizontal shaft passes through one end of the socket plate. A spring is sleeved on the outer side of the horizontal shaft. Side support plates are provided on both the left and right sides of the base plate. The height of the side support plates is greater than the lowest point of the socket plate.

[0017] By adopting the above technical solution, the sleeve plate slides on the horizontal axis surface inside the vertical plate, and the surface spring enables it to return to its original position in a timely manner after movement.

[0018] Furthermore, through openings are fixedly provided on both sides of the middle part of the support frame, and the internal width is greater than the width of the horizontal plate. Two identical support vertical rods are provided on the top of the support frame, and the tops of the two support vertical rods are fixedly connected to the outside of the collar.

[0019] By adopting the above technical solution, the tops of the two support vertical rods are fixedly connected to the outside of the collar, and the two sets of support vertical rods can stably support the collar.

[0020] Furthermore, a spring is sleeved on the outside of the elastic switch, and there are two elastic switches, which are electrically connected to two electromagnetic plates respectively.

[0021] By adopting the above technical solution, two elastic switches control two electromagnetic plates. When the elastic switches are moved away from the electromagnetic plates, the electromagnetic valve in the middle is closed.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. In this application, two symmetrical socket plates are used to fix the hot air pipe below the supply equipment. The moving rod moves the socket plates away from and closer to the hot air pipe. When the pipe expands, it moves the socket plates away from the pipe. The horizontal plate closes the solenoid valve above, cuts off the heat source or gas supply in time, prevents the hot air from expanding continuously in the closed system, avoids the pressure exceeding the pressure limit of the equipment, and prevents the hose from rupturing due to the pressure of the hot air.

[0024] 2. In this application, by cutting off the supply of hot gas, the temperature and pressure of the equipment drop rapidly, reducing fatigue cracks in metal parts caused by thermal expansion and contraction, and preventing the core risk of uncontrolled pressure leading to explosion or leakage, thus avoiding the occurrence of equipment damage, fire and personal injury.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-5 This application discloses a hot air supply device, including a base plate 1. Two identical vertical plates 11 are arranged on both sides of the lower surface of the base plate 1. A horizontal shaft 12 is fixedly arranged on the inner side of the vertical plate 11. The horizontal shaft 12 passes through one end of a sleeve plate 14. A spring is sleeved on the outer side of the horizontal shaft 12. Side support plates 15 are arranged on both the left and right sides of the base plate 1. The height of the side support plates 15 is greater than the lowest point of the sleeve plate 14. The sleeve plate 14 slides on the surface of the horizontal shaft 12 inside the vertical plate 11. The spring on the surface allows it to return to its original position in time after movement.

[0033] A support frame 3 is fixedly mounted on the upper surface of the seat plate 1. Through openings are fixedly mounted on both sides of the middle of the support frame 3, and the internal width is greater than that of the horizontal plate 18. Two identical vertical support rods 5 are mounted on the top of the support frame 3. The tops of both vertical support rods 5 are fixedly connected to the outside of the collar 16. The two sets of vertical support rods 5 can stably support the collar 16. A through groove is fixedly mounted in the middle of the top of the support frame 3, and an electromagnetic plate 8 is fixedly mounted on its inner wall. An elastic switch 19 is mounted in the middle of one side of the electromagnetic plate 8. A spring is sleeved on the outside of the elastic switch 19. There are two elastic switches 19, and the two elastic switches 19 are electrically connected to the two electromagnetic plates 8 respectively. The two elastic switches 19 control the two electromagnetic plates 8. When the elastic switches 19 are moved away from the electromagnetic plates 8, the electromagnetic valve 7 in the middle is closed.

[0034] A horizontal plate 18 is fixedly installed at the end of the switch 19 away from the electromagnetic plate 8. A slider 9 is fixedly installed at one end of the horizontal plate 18. A moving rod 13 is fixedly inserted into the middle of the slider 9. The moving rod 13 is L-shaped. The horizontal position of the bottom of the moving rod 13 is away from the edge of the base plate 1. A limiting rectangular plate 2 is slidably sleeved on the outer circumferential surface of the moving rod 13 near the top. One end of the limiting rectangular plate 2 is fixedly installed in the middle of one side of the base plate 1. A sliding groove is provided in the middle of the limiting rectangular plate 2. The L-shaped moving rod 13 avoids movement conflict with the base plate 1. The limiting rectangular plate 2 restricts the movement trajectory of the moving rod 13 and prevents the moving rod 13 from deviating during movement.

[0035] A connecting plate 14 is fixedly installed at the bottom of the moving rod 13. The connecting plate 14 is wavy and there are two connecting plates 14. The two connecting plates 14 are symmetrically arranged at the bottom of the base plate 1. The wavy connecting plate 14 makes it easier to clamp heating pipes of different specifications and increases its adaptability to the environment. An arc rod 17 is fixedly installed at the middle position of the top of the connecting plate 14. A limiting slide plate 20 is fixedly installed at the top of the arc rod 17. A moving plate 10 is fixedly installed at one end of the limiting slide plate 20. The end of the moving plate 10 away from the limiting slide plate 20 is fixedly sleeved on the outer side of the middle part of the moving rod 13. The limiting slide plate 20 is set in a "T" shape. By setting the moving plate 10 to move with the moving rod 13, it is ensured that the limiting slide plate 20 at one end can slide smoothly. The outer side of the top of the limiting slide plate 20 is slidably connected to the groove on the lower surface of the base plate 1.

[0036] A solenoid valve 7 is fixedly installed on one side of the top of the solenoid plate 8 and electrically connected to it. A connector 4 is fixedly installed at the bottom of the solenoid valve 7. The bottom of the connector 4 is tapered. Solenoid plates 8 are installed on both sides of the solenoid valve 7. Flexible switches 19 are inserted into the outer side of both solenoid plates 8. The connector 4 passes through the middle of the base plate 1. The tapered connector 4 facilitates tight connection with the heating pipe. The power supply demand of the solenoid plate 8 to the inner solenoid valve 7 is controlled by the flexible switch 19. A pipe is fixedly inserted into the middle of the solenoid valve 7. A union connector 6 is fixedly installed at the top of the pipe. A collar 16 is sleeved on the outer side of the middle of the union connector 6. A support rod 5 is fixedly installed on the outer side of the collar 16. The bottom of the support rod 5 is fixedly installed on the top of the support frame 3.

[0037] The operating principle of the hot gas supply device in this embodiment is as follows: When the hot gas supply is in operation, the connector 4 is connected to the external heating pipeline equipment. The two sleeve plates 14 on both sides are sleeved on the outside of the heating equipment. After the heating continues for a period of time, the heating pipeline equipment will expand when heated, pushing the two sleeve plates 14 on both sides to move to both sides. When the sleeve plates 14 move, the moving rod 13 drives the horizontal plate 18 to move horizontally. The horizontal plate 18 pulls the elastic switch 19 to move away from the electromagnetic plate 8. After the elastic switch 19 moves to the position, it closes the electromagnetic plate 8, so that the electromagnetic valve 7 in the middle closes the upper heating pipeline, cutting off the heating work below. Timely cutting off the heat source or gas supply can prevent the hot gas from continuing to expand in the closed system, avoid pressure exceeding the pressure limit of the equipment, prevent the explosion caused by excessive pressure, eliminate the risk of hot gas leakage and burns, prevent the hose from rupturing due to hot gas compression, avoid structural damage, and after the supply is cut off, the equipment temperature and pressure drop rapidly, reducing fatigue cracks in metal parts caused by thermal expansion and contraction.

All technical solutions falling within the scope of this utility model's concept are protected.
