[0002] In the metallurgical industry, a heating furnace is a device (industrial furnace) that heats materials or workpieces (typically metal) to rolling or forging temperatures. Regenerative burners are combustion devices used in heating furnaces, distributing fuel and combustion air and spraying them in a specific pattern for post-combustion. They are widely used in the field of combustion-assisting devices.

[0003] However, in the prior art, when fuel gas and flame-retardant gas are introduced into the regenerative burner, since both fuel gas and flame-retardant gas are doped with solid impurities, these solid impurities will not be completely burned when the incoming fuel gas is burned, and some unburned solid impurities will remain inside the burner. If the solid impurities are not cleaned in time, the solid impurities will cause turbulence in the airflow, so that the fuel gas and flame-retardant gas cannot contact well, thereby slowing down the combustion speed and reducing the flame temperature, further affecting the combustion efficiency. Utility Model Content

[0023] The cleaning mechanism 2 includes a screw 21, a threaded seat 22 is fixedly installed at one end of the connecting tube 11, an air guide tube 23 is provided inside the connecting tube 11, a circular brush 24 is fixedly installed on the outer wall of the air guide tube 23, and a rotating handle 25 is fixedly installed on the outer wall of the screw 21. The screw 21 is threadedly connected to the inside of the threaded seat 22, one end of the screw 21 passes through one end of the connecting tube 11 and is fixed to one end of the circular brush 24, and the outer wall of the circular brush 24 is in contact with the inner wall of the connecting tube 11.

[0024] The following describes in detail the specific configuration and function of this embodiment. By installing a first filter plate 14 on the inner wall of the gas inlet pipe 12 and a second filter plate 15 on the inner wall of the air inlet pipe 13, the first filter plate 14 and the second filter plate 15 can filter the gas or air entering the connecting pipe 11, thereby effectively preventing solid impurities in the gas and air from entering the connecting pipe 11.

[0025] By rotating the handle 25, the handle 25 drives the screw 21 to rotate on the internal thread of the threaded seat 22, which facilitates the screw 21 to move left and right inside the connecting pipe 11. At the same time, the screw 21 will drive the annular brush 24 on the outer wall to move. The annular brush 24 will clean the inner wall of the connecting pipe 11, and when it contacts the outer walls of the No. 1 filter plate 14 and the No. 2 filter plate 15, it can clean up the solid impurities on the outer walls of the No. 1 filter plate 14 and the No. 2 filter plate 15, so that the fixed impurities can be cleaned in time, and the solid impurities are prevented from accumulating on the outer walls of the No. 1 filter plate 14 and the No. 2 filter plate 15, preventing them from affecting the gas and air entering the connecting pipe 11, preventing the combustion speed from slowing down and reducing the flame temperature, and will not affect the combustion efficiency.

[0026] Example 2: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the discharge mechanism 3 includes a sealing round cap 31, and a suction pipe 32 is passed through the outer wall of the air guide tube 23 and the outer wall of the circular brush 24. A connecting column 33 is fixedly installed at one end of the screw 21. A vent hole 34 is opened through the connecting column 33 and one end of the screw 21. The vent hole 34 is connected to the air guide tube 23, and the sealing round cap 31 is sleeved on the outer wall of the connecting column 33.

[0027] The effect achieved by the entire embodiment is that by connecting the connecting column 33 to the external small suction pump and operating the suction pump, the suction force generated by the suction pump is transmitted to the interior of the plurality of suction pipes 32 through the vent holes 34. The plurality of suction pipes 32 can absorb solid impurities on the inner wall of the connecting pipe 11 and discharge the solid impurities from the interior of the connecting pipe 11. Secondly, by rotating the handle 25 and driving the external small suction pump to rotate together, the screw 21 can drive the plurality of suction pipes 32 to move through the air guide pipe 23, thereby facilitating the movement of the plurality of suction pipes 32 inside the connecting pipe 11 and fully discharging the solid impurities inside the connecting pipe 11.

[0028] The provision of the sealing round cap 31 can seal the connecting column 33 , preventing the gas or air inside the connecting pipe 11 from flowing out from the connecting column 33 , thereby improving the sealing performance of the connecting column 33 .

[0029] The method of use and working principle of this device: First, install the regenerative burner body 1 to a suitable position.

Then, when it is necessary to clean the solid impurities, by rotating the handle 25, the handle 25 drives the screw 21 to rotate on the internal thread of the threaded seat 22, which facilitates the screw 21 to move left and right inside the connecting pipe 11. At the same time, the screw 21 will drive the circular brush 24 on the outer wall to move, and the circular brush 24 will clean the inner wall of the connecting pipe 11, and when it is in contact with the No. 1 filter screen 14 and When the outer wall of the No. 2 filter screen plate 15 contacts, the solid impurities on the outer walls of the No. 1 filter screen plate 14 and the No. 2 filter screen plate 15 can be cleaned up, and the fixed impurities can be cleaned in time. Finally, by pulling out the sealing round cap 31 from the outer wall of the connecting column 33, and then connecting the connecting column 33 with the external small suction pump, by running the suction pump, the suction force generated by the suction pump is transmitted to the interior of the several groups of suction pipes 32 through the vent hole 34, and the several groups of suction pipes 32 can suck away the solid impurities on the inner wall of the connecting pipe 11, and can discharge the solid impurities from the interior of the connecting pipe 11. Afterwards, by rotating the handle 25 and driving the external small suction pump to rotate together, the screw 21 can drive the several groups of suction pipes 32 to move through the air guide pipe 23, so that the several groups of suction pipes 32 can move inside the connecting pipe 11, and can fully discharge the solid impurities inside the connecting pipe 11.
