Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof pipeline heaters, and particularly relates to a high-temperature thermal radiation type explosion-proof pipeline heater. Background Technique

[0002] The high-temperature thermal radiation type explosion-proof pipeline heater is a heating device that can work under high temperature and explosion-proof requirements. It is mainly used in the industrial field, especially in pipeline systems that need to handle flammable and explosive gases or liquids. The high-temperature thermal radiation type explosion-proof pipeline heater mainly consists of a heater body, an explosion-proof device, a control system, etc. Among them, the heater body contains electric heating elements for generating heat; the explosion-proof device ensures that even in case of abnormal situations during the heating process, it can be controlled in time to avoid causing danger; the control system is responsible for monitoring and adjusting the operating state of the heater.

[0003] The high-temperature thermal radiation type explosion-proof pipeline heater generates heat by means of electric heating and uses the principle of thermal radiation to evenly transfer the heat to the pipeline. Its explosion-proof design ensures that the equipment can also work safely in a flammable and explosive environment. Through the real-time monitoring and adjustment of the control system, the pipeline temperature can be kept constant and the occurrence of local overheating can be avoided.

[0004] However, when the high-temperature thermal radiation type pipeline heater is heating, it achieves a higher heating effect through the reflection of the inner wall on the heat outside the heating pipe. After the pipeline heater has been used to heat substances for a long time, there will be some substances attached to the inner wall of the pipeline heater after heating, which will lead to a decrease in the heating effect radiated by the inner wall, and then reduce the service performance and service life of the overall pipeline heater. In the prior art, multiple sets of scraping plates and flow guiding devices are usually arranged in the pipeline. Their structures are numerous and occupy a large amount of internal space of the pipeline, resulting in a reduction in the occupancy rate of the medium space in the heating pipeline and affecting the normal use of the equipment. Moreover, the two ends of the pipeline are inconvenient to clean and are easily overlooked. Therefore, those skilled in the art have provided a high-temperature thermal radiation type explosion-proof pipeline heater to solve the problems raised in the above background technique.

The upper output end of the motor 9 is connected to a drive shaft 10. The drive shaft 10 is inserted into the reflection housing 1 from bottom to top. A spiral scraper 13 is arranged in the reflection housing 1. Turbulence holes 14 are formed in the spiral scraper 13. By rotating the spiral scraper 13 and cooperating with the turbulence holes 14, the air medium in the reflection housing 1 can be disturbed, thereby improving the heating effect of the heating pipe 5. A scraping bar 11 is installed at the bottom of the spiral scraper 13. A support shaft 12 is installed on the scraping bar 11.

[0022] Please refer to Figure 2 , Figure 3, the scraping strip 11 is fixedly installed on the drive shaft 10, and the scraping strip 11 is fixedly installed on the spiral scraping plate 13 through the support shaft 12. When the motor 9 drives the drive shaft 10 to rotate, the rotation of the drive shaft 10 drives the scraping strip 11 and the spiral scraping plate 13 to rotate. The inner side of the spiral scraping plate 13 contacts the outer wall of the heating pipe 5, the outer side of the spiral scraping plate 13 contacts the inner wall of the reflection housing 1, and the upper end of the spiral scraping plate 13 contacts the inner wall of the top side of the reflection housing 1. The rotation of the spiral scraping plate 13 can clean the outer wall of the heating pipe 5, the inner wall of the reflection housing 1, and the top side wall of the reflection housing 1. The scraping strip 11 contacts the inner wall of the bottom side of the reflection housing 1. When the scraping strip 11 rotates, it can sweep the impurities cleaned down into the discharge port 7 while cleaning the bottom side wall of the reflection housing 1. The discharge port 7 is opened at the bottom of the reflection housing 1, and a solenoid valve 8 is arranged in the discharge port 7. When the solenoid valve 8 is opened, the impurities can be discharged.

[0023] The high-temperature thermal radiation type explosion-proof pipeline heating equipment in this utility model consists of an explosion-proof reflection housing 1 and a heater 4. Among them, the heater 4 is arranged above the reflection housing 1 and is connected to the upper end of the reflection housing 1 in a flange connection manner. A heating pipe 5 is connected to the lower end of the heater 4, and the heating pipe 5 is inserted into the reflection housing 1 from top to bottom;

[0024] An air outlet pipe 2 is installed on the upper part of one side of the reflection housing 1, and an air inlet pipe 3 is installed on the lower part of the same side.

When the motor 9 drives the drive shaft 10 to rotate, the rotation of the drive shaft 10 drives the scraping strip 11 to rotate. When the scraping strip 11 rotates, it drives the spiral scraping plate 13 to rotate through the support shaft 12 while cleaning the bottom side wall of the reflection housing 1, so as to clean the outer wall of the heating pipe 5, the inner wall of the reflection housing 1, and the top side wall of the reflection housing 1. The impurities cleaned down fall to the bottom of the reflection housing 1 along with the spiral scraping plate 13 and the flow disturbance holes 14 on the spiral scraping plate 13. Under the scraping of the scraping strip 11, the impurities are swept into the discharge port 7. When the solenoid valve 8 is opened, the impurities can be discharged;
