Description

Technical Field

[0001] The utility model relates to the technical field of gasification burners, in particular to a quick replacement device for a gasification burner. Background Art

[0002] A gasification burner is a device that converts liquid fuel or high-boiling-point liquids (such as heavy oil and tar) into combustible gas. Its working principle is to heat the liquid fuel to above the boiling point of its volatile components through a high-temperature medium, causing it to evaporate and form combustible gas. This gas is then ejected through a nozzle, mixed with air, and ignited, ultimately generating high-temperature combustion in the combustion chamber, releasing energy.

[0003] At present, the gasification burner is fastened by a high-pressure flange connection. One burner flange has 20 bolts (the bolts and nuts are M39, 58.8-60mm across the side and approximately 66.44mm across the diagonal). Each time the burner is replaced, the bolts need to be disassembled and installed one by one, and a hydraulic wrench needs to be used to tighten them one by one, which takes a long time. In addition, due to the small construction space, only two people can work, resulting in a large workload, long time consumption, and low efficiency in normal burner replacement.

[0029] The small elbow 12 is arranged on one side of the large elbow 5, and the small elbow 12 cooperates with the large elbow 5, and the locking portion 1201 on the surface of the small elbow 12 is tightly engaged with the hook portion 501 at one end of the large elbow 5; one end of the large elbow 5 is hinged to the first support 3 on the outer wall of the burner body 1 through the first rotating shaft 4; the top of the head screw 7 is fixed with a rotating head 8, and the interior of the rotating head 8 is provided with a through hole 9, and the through hole 9 is arranged along the radial direction of the rotating head 8; the bottom end of the head screw 7 is connected to the top of the pressure cover 11 The second threaded hole 10 is threadedly connected to the burner body 1; one end of the small elbow 12 is hinged to the second support 14 on the other outer wall of the burner body 1 through the second rotating shaft 13, and a locking screw 23 is provided on the second support 14. The locking screw 23 extends from the surface of the second support 14 toward the second rotating shaft 13. When the position of the second rotating shaft 13 needs to be fixed, the locking screw 23 is abutted against the outer circumferential surface of the second rotating shaft 13 along the radial direction of the second rotating shaft 13 to achieve locking of the second rotating shaft 13.

[0030] Specifically, the large elbow 5 is turned over to rotate around the first rotating shaft 4, and the large elbow 5 is placed above the pressure cover 11. The machine head screw 7 inside the first threaded hole 6 is screwed into the second threaded hole 10 at the top of the pressure cover 11, and then the small elbow 12 is rotated to rotate around the second rotating shaft 13. The small elbow 12 is engaged with the hook portion 501 at one end of the large elbow 5 through the locking portion 1201, and the second rotating shaft 13 is locked by the locking screw 23; then, the tool is inserted into the through hole 9 of the rotating head 8, and the machine head screw 7 is tightened to fix the pressure cover 11 on the burner body 1. This design greatly simplifies the operating steps, takes short disassembly and assembly time, is highly efficient, can minimize the burner replacement time, and avoids the furnace temperature dropping too fast when replacing the burner, thereby also saving labor costs to the greatest extent.

[0031] It should be noted that the burner body 1 is threadedly connected to the equipment body. Therefore, when the head screw 7 is tightened, the threaded connection between the burner body 1 and the equipment body is also tightened to achieve the installation of the burner body 1; or when the head screw 7 is loosened, the threaded connection between the burner body 1 and the equipment body is also loosened to achieve the disassembly of the burner body 1.

[0032] When the burner body 1 is in use, the pressure cover 11 and the large elbow 5 are clamped to avoid affecting the use of the burner body 1 and the burner port 2.

[0033] A sealing ring 15 is provided at the bottom end of the gland 11 , and an annular groove 22 is provided at the bottom end of the gland 11 on one side of the sealing ring 15 .

[0036] Specifically, when sealing, the pressure cover 11 is placed on the burner port 2. At this time, the sealing ring 15 at the bottom end of the pressure cover 11 is inserted into the sealing groove 16 at the top end of the burner port 2, thereby improving the sealing between the pressure cover 11 and the burner port 2. At the same time, the sealing ring 15 presses down the upper pressure ring 17 so that it overcomes the elastic force of the support spring 18 and moves downward. The upper pressure ring 17 squeezes the sealing air bag 21 inside the sealing cavity 20 through the lower pressure ring 19, so that the top end of the sealing air bag 21 bulges and fills the annular groove 22 at the bottom end of the pressure cover 11, thereby resealing the pressure cover 11 and the burner port 2. The double sealing structure is adopted to improve the sealing and prevent gas leakage.

[0037] When the embodiment of the present application is in use: first, the device is mainly composed of a large elbow 5, a machine head screw 7, a small elbow 12, and a pressure cover 11. The burner flange is fixed and sealed by using the large elbow 5, the machine head screw 7, the small elbow 12, and the pressure cover 11 instead of the flange bolts. When sealing, the pressure cover 11 is covered on the burner port 2. At this time, the sealing ring 15 at the bottom end of the pressure cover 11 is stuck into the sealing groove 16 at the top end of the burner port 2, thereby improving the sealing between the pressure cover 11 and the burner port 2. At the same time, the sealing ring 15 presses down the upper pressure ring 17 to overcome the elastic force of the support spring 18 and move downward. The upper pressure ring 17 squeezes the sealing air bag 21 inside the sealing cavity 20 through the lower pressure ring 19, inflates the sealing air bag 21, and makes the top of the sealing air bag 21 bulge and fill the annular groove 22 at the bottom end of the pressure cover 11, thereby sealing the pressure cover 11 and the burner port. 2 is sealed again, and a double sealing structure is adopted to improve the sealing and prevent gas leakage.

The head screw 7 inside the first threaded hole 6 is screwed into the second threaded hole 10 at the top of the pressure cover 11, and then the small elbow 12 is rotated to rotate it around the second rotating shaft 13. The small elbow 12 is engaged with the hook portion 501 at one end of the large elbow 5 through the locking portion 1201. Then, the tool is inserted into the through hole 9 inside the rotating head 8, and the head screw 7 is tightened to fix the pressure cover 11 on the burner body 1. This design greatly simplifies the operating steps, takes short time to disassemble and assemble, and is highly efficient. The use of this technology can minimize the burner replacement time and avoid the furnace temperature dropping too fast when replacing the burner, thereby also saving labor costs to the greatest extent.
