Description

Technical Field

[0001] This utility model relates to the field of gas-fired infrared radiation heating devices, specifically a gas-fired infrared radiation heating device. Background Technology

[0002] Gas-fired infrared radiant heating devices use natural gas as fuel. The natural gas mixes and burns with air in the burner to produce high-temperature flue gas. Part of the heat from the high-temperature flue gas is transferred to the radiant tube (made of high-temperature resistant metal or ceramic, including supply and return air ducts) through the radiant tube. After absorbing the heat, the radiant tube emits infrared radiation waves, which penetrate the air like sunlight and directly hit the surface of the object, converting into heat energy for heating. The other part of the heat is discharged with the flue gas after being utilized by a waste heat recovery device. At the same time, the control system maintains the temperature of the radiant tube by adjusting the gas flow and pulse solenoid valve, combined with temperature sensor data, to ensure stable output of infrared radiation.

[0003] In existing technologies, the radiant tubes in gas-fired infrared radiant heating devices have high temperatures. To prevent people from accidentally touching the radiant tubes in these devices, they are usually installed at high locations for heating.

[0004] However, in traditional gas-fired infrared radiant heating devices, the hot air inside the reflector cannot flow downwards, resulting in higher temperatures at higher elevations and lower temperatures at the bottom of the room, leading to poor heating performance. Furthermore, since gas-fired infrared radiant heating devices are installed at high elevations, personnel still need to climb up to clean the radiant tubes when they are covered with dust, which is inconvenient for actual use. Therefore, this utility model proposes a gas-fired infrared radiant heating device to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a gas-fired infrared radiation heating device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas-fired infrared radiant heating device, comprising: a radiant tube, the radiant tube being installed on the main body of the gas-fired radiant heating device, a wind guide plate being rotatably connected to the side of the main body of the gas-fired radiant heating device, an air pump being connected to the upper surface of the main body of the gas-fired radiant heating device, an upper air supply pipe being connected to the air outlet end of the air pump, a stainless steel corrugated pipe being connected to the side of the upper air supply pipe, the other end of the stainless steel corrugated pipe being connected to a stainless steel pipe, an electromagnetic valve being installed on the stainless steel pipe, and a plurality of air jets being installed on the stainless steel pipe.

[0007] The wind guide plate is connected to the transmission end of the first servo motor.

[0008] Preferably, the first servo motor is fixedly connected to the side of the main body of the gas radiant heating device, and a limit block is fixedly connected to the upper surface of the main body of the gas radiant heating device, the limit block being a square plate-shaped structure.

[0009] Preferably, a second servo motor is fixedly connected to the side of the main body of the gas radiant heating device, and the transmission end of the second servo motor is fixedly connected to the screw.

[0010] Preferably, the screw is threadedly connected to the mounting plate, and the other end of the screw is rotatably connected to the main body of the gas radiant heating device.

[0011] Preferably, an upper protective plate is fixedly connected to the main body of the gas radiant heating device.

[0012] Preferably, the stainless steel pipe is installed on the side of the mounting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The gas-fired infrared radiant heating device proposed in this utility model automatically cleans the radiant tubes by opening a solenoid valve installed on a stainless steel pipe above the radiant tubes, activating an air pump and coordinating with the air supply pipe. Gas is then ejected from a jet nozzle installed on the stainless steel pipe above the radiant tubes, accelerating the downward flow of hot air within the reflector mounted on the main body of the gas-fired radiant heating device. This reduces the phenomenon of higher temperatures at higher elevations and lower temperatures at the bottom of the room, improving the heating effect of the device. During the process, a first servo motor can be activated to rotate the air guide plate, changing its angle to guide the blown hot air. Furthermore, by activating the solenoid valve installed on the stainless steel pipe below the radiant tubes, the gas ejected from the jet nozzles cleans the area below the radiant tubes. Conversely, by closing the solenoid valve below the radiant tubes and opening the solenoid valve above the radiant tubes, the gas ejected from the jet nozzles cleans the area above the radiant tubes. This achieves automatic cleaning of the radiant tubes mounted on the main body of the gas-fired radiant heating device, improving its heating effect. The process eliminates the need for manual cleaning by personnel climbing to higher elevations, making it convenient for users. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a gas-fired infrared radiation heating device, comprising: a radiation tube 2, the radiation tube 2 being installed on the main body 1 of the gas-fired radiation heating device, a wind guide plate 10 being rotatably connected to the side of the main body 1 of the gas-fired radiation heating device, an air pump 4 being connected to the upper surface of the main body 1 of the gas-fired radiation heating device, an upper air supply pipe 5 being connected to the air outlet end of the air pump 4, a stainless steel corrugated pipe 6 being connected to the side of the upper air supply pipe 5, the other end of the stainless steel corrugated pipe 6 being connected to a stainless steel pipe 7, an electromagnetic valve 8 being installed on the stainless steel pipe 7, a plurality of jet nozzles 15 being installed on the stainless steel pipe 7, and the wind guide plate 10 being connected to the transmission end of a first servo motor 9.

[0025] In practical use, the solenoid valve 8, the first servo motor 9, and the second servo motor 12, among other structures configured within the device, all adopt a high-temperature resistant design. Their mechanical structure and material selection meet the temperature resistance requirements under actual working conditions, ensuring stable performance of the equipment in high-temperature operating environments. The solenoid valve 8, installed on the stainless steel pipe 7 above the radiant tube 2, can be activated via the control device on the device, connecting the stainless steel pipe 7 to the stainless steel corrugated pipe 6. Activating the air pump 4 in conjunction with the air supply pipe 5 allows gas to be ejected through the jet nozzle 15 installed on the stainless steel pipe 7 above the radiant tube 2, accelerating the downward flow of hot air within the reflector installed on the main body 1 of the gas radiant heating device. During the process, the first servo motor 9 can be started to rotate the air guide plate 10 to change its angle. The air guide plate 10 guides the blown hot air. When the main body 1 of the gas radiant heating device is not in use, the air pump 4 is started to start the solenoid valve 8 installed on the stainless steel pipe 7 below the radiant tube 2. The gas sprayed by the jet nozzle 15 installed on the stainless steel pipe 7 cleans the area below the radiant tube 2. Then the solenoid valve 8 installed on the stainless steel pipe 7 below the radiant tube 2 is closed, and the solenoid valve 8 installed on the stainless steel pipe 7 above the radiant tube 2 is started to open. The gas sprayed by the jet nozzle 15 installed on the stainless steel pipe 7 cleans the area above the radiant tube 2.

[0026] Example 2: Based on Example 1, a first servo motor 9 is provided for ease of use. The first servo motor 9 is fixedly connected to the side of the main body 1 of the gas radiant heating device. A limit block 14 is fixedly connected to the upper surface of the main body 1 of the gas radiant heating device. The limit block 14 has a square plate structure. The screw 13 is driven to rotate by starting the first servo motor 9.

[0027] A second servo motor 12 is fixedly connected to the side of the main body 1 of the gas radiant heating device. The transmission end of the second servo motor 12 is fixedly connected to the screw 13. The screw 13 rotates along the threaded hole opened on the mounting plate 11.

[0028] The screw 13 is threadedly connected to the mounting plate 11, and the other end of the screw 13 is rotatably connected to the main body 1 of the gas radiant heating device. The mounting plate 11 is set between the upper surface of the main body 1 of the gas radiant heating device and the lower surface of the upper protective plate 3, and can be moved through the mounting plate 11.

[0029] Stainless steel pipe 7 is installed on the side of mounting plate 11. By starting air pump 4, air is supplied to stainless steel corrugated pipe 6 through upper air supply pipe 5, and then to stainless steel pipe 7 through stainless steel corrugated pipe 6. The air sprayed by air jet head 15 is sprayed onto the surface of radiant tube 2, which can clean the floating dust and impurities on the surface of radiant tube 2. With the movement of mounting plate 11, the surface of radiant tube 2 can be thoroughly cleaned. During the process, no personnel need to climb to a height for cleaning, which is convenient for actual use. During the process, limit block 14 is used to limit the movement range of mounting plate 11.

[0030] Example 3: Based on Example 2, in order to improve the performance of the device, a gas radiant heating device body 1 is provided. An upper protective plate 3 is fixedly connected to the gas radiant heating device body 1. The upper protective plate 3 can protect the screw 13 and prevent the screw 13 from interfering with the stainless steel corrugated pipe 6. The screw 13 lead screw drive part is covered with a telescopic protective sleeve (not shown in the figure), and the inside is filled with high temperature resistant grease to form a continuous oil film environment.

[0031] In actual use, the solenoid valve 8 installed on the stainless steel pipe 7 above the radiant tube 2 is opened, and the air pump 4 is started in conjunction with the air supply pipe 5. The jet nozzle 15 installed on the stainless steel pipe 7 above the radiant tube 2 sprays out gas, accelerating the downward flow of hot air inside the reflector installed on the main body 1 of the gas radiant heating device. This reduces the phenomenon of higher temperature at higher elevations and lower temperature at the bottom of the room, improving the heating effect of the device. During the process, the first servo motor 9 can be started to rotate the air guide plate 10 to change the angle and guide the blown hot air. The solenoid valve 8 installed on the stainless steel pipe 7 below the radiant tube 2 can be started, and the gas sprayed by the jet nozzle 15 can clean the area below the radiant tube 2. Then, the solenoid valve 8 installed on the stainless steel pipe 7 below the radiant tube 2 is closed, and the solenoid valve 8 installed on the stainless steel pipe 7 above the radiant tube 2 is opened, and the gas sprayed by the jet nozzle 15 cleans the area above the radiant tube 2. In this way, the radiant tube 2 installed on the main body 1 of the gas radiant heating device is automatically cleaned, improving its heating effect. The process does not require personnel to climb to a height for manual cleaning, making it convenient for users.

[0032] 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.
