[0027] A hydraulic rod 9 is installed at the center of the bottom end of the oxygen supply box 3. A sealing plate 10 is installed at the end of the hydraulic rod 9. The sealing plate 10 is located inside the oxygen supply pipe 12. The center of the bottom end of the oxygen supply box 3 is connected to the oxygen supply pipe 12. The oxygen supply pipe 12 is located inside the boiler conveying pipeline 1. The hydraulic rod 9 can extend and retract in the oxygen supply pipe 12, thereby driving the sealing plate 10 to move up and down.

[0028] The outer wall of the oxygen supply pipe 12 is provided with oxygen supply holes a15, b14 and c13 evenly spaced from bottom to top along its axis. The top end of the oxygen supply pipe 12 has an opening and the bottom end has no opening. Three sets of oxygen supply holes are provided on the outer wall of the oxygen supply pipe 12 from bottom to top. Oxygen can be supplied to the interior of the boiler supply pipeline 1 through the oxygen supply holes. The amount of oxygen supplied is controlled by the number of the three sets of oxygen supply holes that are opened.

[0029] The top of the oxygen delivery box 3 is equipped with a hydraulic cylinder 6, and the top of the hydraulic rod 9 is connected to the drive end of the hydraulic cylinder 6. The hydraulic cylinder 6 can control the lifting and lowering of the hydraulic rod 9.

[0030] The oxygen supply box 3 has an oxygen inlet hole 4 on its side wall, and an oxygen inlet assembly 5 is installed in the oxygen inlet hole 4. An external oxygen source can be connected to the oxygen supply box 3 through the oxygen inlet assembly 5.

[0031] The outer wall of the sealing disc 10 is fitted with a sealing ring 11, and the outer wall of the sealing ring 11 is fitted to the inner wall of the oxygen delivery tube 12. The sealing ring 11 can seal the space between the sealing disc 10 and the oxygen delivery tube 12.

[0032] The oxygen inlet assembly 5 includes a connecting pipe 52, a sealing cylinder 51, and an oxygen pipe 53. The oxygen pipe 53 is fixed inside the oxygen inlet hole 4. Both the connecting pipe 52 and the oxygen pipe 53 are inserted into the sealing cylinder 51. The inner wall of the sealing cylinder 51 has an internal thread 16, and the outer wall of the connecting pipe 52 has an external thread 21. The end of the oxygen pipe 53 is located inside the sealing cylinder 51 and a limiting ring 17 is installed. The sealing cylinder 51 is fixed inside the oxygen inlet hole 4. The connecting pipe 52 is used to connect to an external oxygen source. The oxygen pipe 53 can deliver oxygen into the oxygen delivery box 3. The sealing cylinder 51 can move outside the oxygen pipe 51. The limiting ring 17 restricts the range of movement of the sealing cylinder 51 outside the oxygen pipe 51. The outer wall of the oxygen pipe 53 is fitted to the inner wall of the sealing cylinder 51.

[0033] The outside of the connecting pipe 52 is fitted inside the sealing cylinder 51 with a sealing assembly. The sealing assembly includes a rubber ring a20 and a rubber ring b18 fitted outside the connecting pipe 52.

[0038] Working process and principle: In use, firstly, connect the external oxygen source through the oxygen inlet assembly 5. Connect the connecting pipe 52 to the external oxygen source, and then insert the connecting pipe 52 into the sealing cylinder 51. At this time, rotate the sealing cylinder 51 outward to connect the connecting pipe 52 to the oxygen pipe 53 through the threaded connection. When oxygen is not needed, the sealing disc 10 is located at the top of the oxygen supply pipe 12, closing the oxygen supply pipe 12. When oxygen needs to be supplied, control the hydraulic rod 9 to extend, and the sealing disc 10 moves to the lower end of the oxygen supply hole a and the upper end of the oxygen supply hole b14. At this time, the oxygen supply hole a is open, and oxygen can be supplied to the inside of the boiler supply pipe 1 through the oxygen supply hole a15. Then, move the sealing disc 10 to the lower end of the oxygen supply hole b14 and the upper end of the oxygen supply hole c13. At this time, the oxygen supply holes a15 and b14 are open, increasing the amount of oxygen supplied. When the sealing disc 10 is placed at the lower end of the oxygen supply hole c13, the oxygen supply hole a15 is closed. With both oxygen supply holes b14 and c13 fully open, the oxygen supply is at its maximum, thus regulating and controlling the oxygen content in boiler delivery pipeline 1.
