Description

Technical Field

[0001] The utility model relates to the technical field of cone oxygen lances, in particular to an oxygen lance cone tube with adjustable taper. Background Art

[0002] The oxygen lance is one of the main process equipment in oxygen converter steelmaking. Its working principle is to blow high-pressure and high-purity oxygen at supersonic speed into the top of the molten metal pool in the converter. It is a tubular device with a high-pressure water cooling protection system, also called a spray gun. Its performance characteristics directly affect the smelting effect and blowing time, thereby affecting the quality and output of steel.

[0003] Publication No. CN216141573U discloses a multi-layer large-taper cone oxygen gun. By setting a cleaning steel frame and a cleaning scraper, and controlling the second servo motor to drive the rotating shaft to rotate on the connecting frame, the cleaning steel frame fixedly connected to the rotating shaft rotates with the rotating shaft until the cleaning scraper installed on the inner side of the cleaning steel frame abuts against the side wall of the large-taper outer tube, and then the first servo motor installed on the outer side wall of the second outer tube is started to drive the gear to rotate. Because the gear is meshed with the inner gear ring installed on the inner side of the rotating ring, the rotating ring can drive the connecting frame and the cleaning steel frame to rotate synchronously. The slider installed at the bottom of the rotating ring slides along the slide groove opened on the top surface of the large-taper outer tube, thereby realizing the use of the cleaning scraper installed on the inner side of the cleaning steel frame to clean the slag adhered to the outer side of the large-taper outer tube in time. However, the patent still has the following problems in actual use:

[0004] By setting a cleaning steel frame and a cleaning scraper, and controlling the second servo motor to drive the rotating shaft to rotate on the connecting frame, the cleaning steel frame fixedly connected to the rotating shaft rotates with the rotating shaft until the cleaning scraper installed on the inner side of the cleaning steel frame abuts against the side wall of the large-taper outer tube, thereby realizing timely cleaning of slag adhered to the outside of the large-taper outer tube by using the cleaning scraper installed on the inner side of the cleaning steel frame. However, when replacing the tube body, because the tube body and the main body are threadedly connected together by means of threads, the thread texture inside the main body is prone to wear, which makes it easy for thread slippage to occur.

[0005] The invention provides an oxygen lance cone tube with adjustable taper, so as to solve the above problems. Utility Model Content

However, when the tube body is replaced, because the tube body and the main body are threadedly connected together by means of threads, the thread texture inside the main body is prone to wear, which makes it easy for the thread to slip.

[0007] To achieve the above object, the utility model provides the following technical solution: an oxygen lance cone tube with adjustable taper, comprising a main body and a tube body, wherein one side of the bottom surface of the main body is fitted and connected with the tube body;

[0008] A sealing gasket is fixedly connected to the top surface of the tube body, and the sealing gasket is closely connected to the body. Connecting blocks are symmetrically installed on both sides of the bottom surface of the body.

[0009] Also includes:

[0010] A buckle assembly is provided inside the connection block;

[0016] Preferably, connecting grooves are symmetrically provided on both sides of the groove, a second spring is fixedly installed inside the connecting groove, and a locking block is fixedly connected to the bottom surface of the second spring.

[0017] Preferably, a plurality of engaging grooves are symmetrically provided on both sides of the engaging block, and the engaging grooves are engaged with the engaging block.

[0018] Preferably, the limiting rod is snap-connected with the limiting groove.

[0019] Compared with the prior art, the utility model has the following beneficial effects: the cone tube of the oxygen lance with adjustable taper is convenient for quick replacement of the tube body by setting a snap assembly, and can also avoid connection by thread, which makes it easy for the thread texture inside the body to slip. At the same time, by setting a connecting groove, a second spring, a snap block and a snap groove, the convex plate can be extended, so that the taper of the tube body is changed, so that the steel slag attached to the convex plate can be more easily removed. The specific contents are as follows:

[0020] 1. By setting a buckle assembly, when the tube body is disassembled, the pressure rod is rotated so that the limit rod on the pressure rod and the horizontal limit groove are on the same horizontal line, so that the first spring can squeeze the sliding block, thereby causing the sliding block to rise, and the rise of the sliding block can drive the rise of the clamping rod, so that the clamping rod and the clamping groove are separated, so that it is convenient to quickly disassemble the tube body. At the same time, when the tube body is installed, the pressure rod is pressed so that the movement of the pressure rod can drive the movement of the pressure block, and the movement of the pressure block can drive the movement of the sliding block, and the movement of the sliding block can drive the movement of the clamping rod, so that the clamping rod and the clamping groove are connected. When the lever is engaged with the first spring, the movement of the sliding block causes the first spring to be squeezed, thereby causing the first spring to be deformed. At the same time, after the pressure rod is pressed to a certain position, the pressure rod is rotated, so that the limiting rod on the pressure rod is separated from the transverse limiting groove. After entering the longitudinal limiting groove, the sliding block squeezes the pressure block and the pressure rod through the action of the first spring, so that the limiting rod and the longitudinal limiting groove are closely fitted, so that when the limiting rod is not disturbed by external artificial force, the limiting rod will not be separated from the longitudinal limiting groove, so that the clamping rod can be limited, so that the pipe body can be better installed.

[0021] 2. By providing a connecting groove, a second spring, a snap block and a snap groove, when it is necessary to adjust the taper of the tube body, the staff pulls the convex plate vigorously so that the snap groove on the convex plate will squeeze the snap block, thereby making the snap block squeeze the second spring, thereby causing the second spring to deform and the snap block to separate from the snap groove. At the same time, after pulling the convex plate to a certain position, the snap groove on the convex plate is again located below the snap block, so that under the action of the snap block and the second spring, the snap block and the snap groove are re-engaged together, thereby limiting the convex plate, allowing the staff to pull out the convex plate as needed, thereby adjusting the taper of the tube body as needed, thereby better removing the slag.

At the same time, the sealing gasket 3 and the main body 1 are closely connected, so that the sealing gasket 3 can prevent the leakage of oxygen entering the tube body 2 from the main body 1. At the same time, the sleeve 501 is made of silicon carbide and has good high temperature resistance.

[0031] The surface of the pressure block 503 on one side away from the pressure rod 502 is fitted with a sliding block 504, and the surface of the sliding block 504 on one side away from the pressure block 503 is fixedly connected with a clamping rod 505. The surface of the clamping rod 505 is sleeved with a first spring 506, and one side of the first spring 506 is fixedly connected to the sliding block 504, and the other side of the first spring 506 is fixedly connected to the sleeve 501. A limiting groove 507 is provided on one side of the surface of the sleeve 501 close to the top, and the limiting groove 507 is internally slidably connected to the limiting rod 508. The limiting rod 508 is fixedly connected to the pressure rod 502, the sliding block 504 is slidably connected to the sleeve 501, and the pressure rod 502 is connected to the sleeve 501 through and through. Figure 3-5As shown, by pressing the pressure rod 502, the movement of the pressure rod 502 can drive the movement of the pressure block 503, and the movement of the pressure block 503 can drive the movement of the sliding block 504, and the movement of the sliding block 504 can drive the movement of the clamping rod 505, so that the clamping rod 505 and the clamping slot 8 are engaged together, and at the same time, the movement of the sliding block 504 squeezes the first spring 506, so that the first spring 506 is deformed. At the same time, after the pressure rod 502 is pressed to a certain position, the pressure rod 502 is rotated, so that the limiting rod 508 on the pressure rod 502 is separated from the horizontal limiting groove 507 and enters the longitudinal limiting groove 507. , through the action of the first spring 506, the sliding block 504 will squeeze the pressing block 503 and the pressing rod 502, so that the limiting rod 508 is tightly fitted with the longitudinal limiting groove 507, so that the limiting rod 508 will not be separated from the longitudinal limiting groove 507 when not interfered by external artificial force, so that the clamping rod 505 can be limited, so that the tube body 2 can be better installed. At the same time, the first spring 506 is a rubber composite spring in the prior art.

[0032] The tube body 2 is symmetrically provided with grooves 6 on both sides, and a convex plate 7 is slidably connected inside the grooves 6. The tube body 2 is symmetrically provided with card grooves 8 on both sides near the top, and the card grooves 8 are connected by card rods 505. Connecting grooves 9 are symmetrically provided on both sides of the grooves 6, and a second spring 10 is fixedly installed inside the connecting grooves 9. A card block 11 is fixedly connected to the bottom surface of the second spring 10. A plurality of card grooves 12 are symmetrically provided on both sides of the card block 11, and the card grooves 12 are connected by card block 11. Figure 6 As shown, the staff pulls the convex plate 7 vigorously, so that the snap-fitting groove 12 on the convex plate 7 squeezes the snap-fitting block 11, so that the snap-fitting block 11 squeezes the second spring 10, so that the second spring 10 is deformed, and the snap-fitting block 11 is separated from the snap-fitting groove 12. At the same time, after the convex plate 7 is pulled to a certain position, the snap-fitting groove 12 on the convex plate 7 is located below the snap-fitting block 11 again, so that the snap-fitting block 11 and the second spring 10 re-engage the snap-fitting groove 12. Together, the convex plate 7 can be limited, so that the staff can pull out the convex plate 7 according to needs, so that the taper of the tube body 2 can be adjusted according to needs, so that the steel slag can be better removed. At the same time, the second spring 10 is also a rubber composite spring in the prior art.

At the same time, the convex plate 7 is also made of silicon carbide.

[0033] The limiting rod 508 is engaged with the limiting groove 507. Figure 5 As shown, the limiting rod 508 is engaged with the limiting slot 507 so as to limit the locking rod 505, thereby making the locking rod 505 and the locking slot 8 more tightly engaged.

Figure 1 - Figure 6 As shown, first, when the tube body 2 is disassembled, the pressure rod 502 is rotated so that the limiting rod 508 on the pressure rod 502 is on the same horizontal line as the horizontal limiting groove 507, so that the first spring 506 can squeeze the sliding block 504, thereby causing the sliding block 504 to rise. The rise of the sliding block 504 can drive the rise of the clamping rod 505, so that the clamping rod 505 is separated from the clamping groove 8, so that it is convenient to quickly disassemble the tube body 2. At the same time, when the tube body 2 is installed, the pressure rod 502 is pressed, so that the movement of the pressure rod 502 can drive the movement of the pressure block 503, and the movement of the pressure block 503 can drive the movement of the sliding block 504, and the movement of the sliding block 504 can drive the movement of the clamping rod 505, so that the clamping rod 505 can be installed. 05 is engaged with the card slot 8, and the movement of the sliding block 504 squeezes the first spring 506, thereby causing the first spring 506 to deform. At the same time, after the pressure rod 502 is pressed to a certain position, the pressure rod 502 is rotated, so that the limiting rod 508 on the pressure rod 502 is separated from the horizontal limiting groove 507, and after entering the longitudinal limiting groove 507, the sliding block 504 squeezes the pressure block 503 and the pressure rod 502 through the action of the first spring 506, so that the limiting rod 508 is tightly fitted with the longitudinal limiting groove 507, so that when the limiting rod 508 is not disturbed by external artificial force, the limiting rod 508 will not be separated from the longitudinal limiting groove 507, so that the card rod 505 can be limited, so that the tube body 2 can be better installed.

[0035] Secondly, when it is necessary to adjust the taper of the tube body 2, the staff pulls the convex plate 7 vigorously so that the engaging groove 12 on the convex plate 7 will squeeze the engaging block 11, so that the engaging block 11 will squeeze the second spring 10, so that the second spring 10 is deformed and the engaging block 11 is separated from the engaging groove 12. At the same time, after pulling the convex plate 7 to a certain position, the engaging groove 12 on the convex plate 7 is located below the engaging block 11 again, so that under the action of the engaging block 11 and the second spring 10, the engaging block 11 and the engaging groove 12 are re-engaged together, so that the convex plate 7 can be limited, so that the staff can pull out the convex plate 7 according to needs, so as to adjust the taper of the tube body 2 according to needs, so that the slag can be better removed.
