Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an oxygen lance slag scraper. Background Art

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

[0003] The oxygen lance scraper described in publication number CN217733175U can be equipped with a mounting frame, an electric push rod and a pressure plate, so that when the device is scraping, the electric push rod on the mounting frame drives the pressure plate to press down and fix the machine base, so as to avoid collision between the machine base and the frame during the scraping process, prevent potential safety hazards, and improve the service life of the device. By arranging a mounting plate, a contact plate and a vibration motor, when scraping, the mounting plate can be in contact with the oxygen lance through the contact plate, and then the vibration motor transmits vibration to the oxygen lance through the mounting plate and the contact plate, so that the unseparated slag is completely separated from the oxygen lance, thereby improving the working quality of the device. However, the prior art still has defects:

[0004] 1. In the prior art, ratchets are arranged on the mounting plate to scrape the slag on the outside of the oxygen lance. However, due to the large gap between the ratchets, a large amount of residue remains on the surface of the oxygen lance, resulting in incomplete scraping.

[0005] 2. Although the prior art transmits vibration to the oxygen lance through a vibration motor to cause the residue of the oxygen lance to fall off, an electric push rod is also provided to drive a pressure plate to press down and fix the machine base to prevent the equipment from vibrating, thereby reducing the vibration amplitude of the oxygen lance. These two structures contradict each other, resulting in an insignificant scraping effect. Utility Model Content

A rotating mechanism 2 is provided on the through hole 1, including a bearing 2.1, a fixed cylinder 2.2, a gear 3.3, a gear 4.4, a shaft 2.5 and a motor 2.6. The bearing 2.1 is clamped on the upper part of the main body 1 and is located above the through hole 1. A fixed cylinder 2.2 is clamped inside. The fixed cylinder 2.2 is a steel cylinder. The gear 3.3 is arranged in the middle of the outer part of the fixed cylinder 2.2. A gear 4.4 is meshed on one side of the gear 3.3. The lower end of the gear 4.4 is fixedly connected with a shaft 2.5. The shaft 2.5 penetrates the upper part of the main body 1 and is fixedly connected with the motor 2.6. The upper end of the fixed cylinder 2.2 is fixedly connected with a mounting plate 3. The motor 2.6 rotates the gear 4.4 to cooperate with the gear 3.3 to drive the fixed cylinder 2.2 to rotate, thereby controlling the rotation of the mounting plate 3.

[0037] A square placement groove is arranged on the upper part of the mounting plate 3, and a through hole 2 is arranged in the middle of the placement groove. The position and size of the through hole 2 correspond to the through hole 1, and it is used to place the oxygen gun. A cylinder 4 is arranged at both ends of the placement groove, and one end of the telescopic rod of the cylinder 4 is fixedly connected to a slider 5. The slider 5 is clamped in the placement groove and can slide left and right. Limiting grooves 10 are arranged on the front and rear walls of the placement groove, and corresponding limiting blocks 11 are arranged on the front and rear walls of the slider 5 and are clamped inside to limit the slider 5.

[0038] The upper end of the slider 5 is fixedly connected to a fixed box 6, the lower end of the fixed box 6 is fixedly connected to a support rod 8, and the opposite end of the support rod 8 is fixedly connected to an arc-shaped scraper 9, which cooperates with the cylinder 4 and the rotating mechanism 2 to clamp the oxygen gun to initially scrape off the residue.

[0039] A cleaning mechanism 7 is provided inside the fixed box 6, including a connecting pipe 7.1, a gear 1 7.2, a gear 2 7.3, a motor 1 7.4, a connecting plate 7.5, a spring 7.6, a brush plate 7.7, a bearing 1 7.8, an air inlet pipe 7.9 and an air pump 7.10. The connecting pipe 7.1 is rotatably connected to the middle of the fixed box 7.1, and the opposite end passes through the wall of the fixed box 6. The gear 1 7.2 is sleeved on the outside of the connecting pipe 7.1 and is provided inside the fixed box 6. The front side of the gear 1 6 is meshed with the gear 2 7.3.

The air is sucked by the air pump 7.10, and the gas is blown toward the oxygen gun through the air inlet pipe 7.9, the connecting pipe 7.1 and the through hole 3, so that the residue brushed by the brush plate 7.7.7 can be blown away to prevent it from adhering to the surface of the oxygen gun.

[0041] When the utility model is implemented, Figure 1 As shown, the oxygen gun is passed through through hole 1 and through hole 2, the cylinder 4 is started, and the sliders 5 are pushed closer to each other to clamp them. When the scraper 9 contacts the surface of the oxygen gun, it stops, and the oxygen gun is driven to rise through the external lifting mechanism. At the same time, the motor 2.6 is started to drive the mounting plate to rotate through the rotating mechanism 2, and the scraper 9 rotates the surface of the oxygen gun to scrape off the residue in all directions. The motor 1 7.4 is started to rotate the brush plate 7.7 through the cleaning mechanism 7 to brush off the residue still remaining on the oxygen gun for a second time, and the air pump 7.10 is started to cooperate with the air inlet pipe 7.9, the connecting pipe 7.1, and the through hole 3 to blow away the residue brushed by the brush plate 7.7 to improve the cleaning efficiency.
