Description

Technical Field

[0002] There are three major equipment in front of the blast furnace, namely: the furnace crane, the tapping machine, and the mud gun. The mud gun is an essential furnace equipment in the smelting industry. Its function is to quickly and accurately block the taphole after the iron is discharged, so that the blast furnace can quickly enter the next cycle of operation. Various types of taphole blocking machines developed in production practice are used to block the taphole. After blocking the gun, the mud gun will stay just above the main iron groove and will be baked at high temperature. Long-term baking will cause damage to the gun body. However, the existing mud gun lacks relevant cooling devices after working for a long time, which will affect the service life of the mud gun and greatly shorten its service life.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1:

[0024] A tool for cooling a blast furnace mud gun. This embodiment is based on the high temperature effect of the mud gun after blocking the iron outlet. In order to achieve rapid cooling of the mud gun, Figure 1-4 As shown, it includes a fixed seat 1 arranged on the top of the mud gun, a sliding rail 2 is welded on the side of the fixed seat 1, a sliding adjustment component is arranged on the sliding rail 2, and the sliding adjustment component includes a first sliding block 3 and a second sliding block 4 that are slidably plugged into the inner wall of the sliding rail 2, a first connecting plate 5 is welded on the top outer wall of the first sliding block 3, a second connecting plate 6 is welded on the top outer wall of the second sliding block 4, an electric telescopic rod 7 is fixedly installed on the side of the first connecting plate 5, and a cooling component is arranged at the bottom of the sliding adjustment component;

[0025] By setting a detachable fixing seat 1 above the mud gun, the cooling component can be quickly fixed, so that different types of mud guns can be cooled, and combined with the multiple flat nozzles 12, high-pressure water can be sprayed to wet and cool the high-temperature gun body, thereby maintaining the gun body within a normal temperature range and greatly improving the service life.

[0026] The sliding adjustment assembly includes a traction rope 8 connected between the first connecting plate 5 and the second connecting plate 6, and a symmetrically distributed safety partition rod 9 is welded on one side of the second connecting plate 6. The cooling assembly includes a rectangular tube 10 welded on the bottom of the second sliding block 4, and the two ends of the bottom outer wall of the rectangular tube 10 are linearly and equidistantly connected with a drainage pipe 11, and the bottom of the drainage pipe 11 is provided with a flat nozzle 12. The bottom of the first sliding block 3 is rotatably connected with an arc tube 13, and the inner wall of the arc tube 13 is provided with threaded holes 15 distributed at equal distances, and the inner wall of the threaded hole 15 is screwed with a high-pressure nozzle 16, and the two ends of the outer wall of the arc tube 13 close to the rectangular tube 10 are connected with a water inlet hose 14;

[0027] By adopting two groups of water spraying mechanisms for water spraying and cooling, and combining with the continuous extension and contraction of the telescopic cylinder 19, the cold water sprayed by the high-pressure nozzle 16 inside the arc tube 13 is driven to continuously swing in an arc shape, thereby expanding the fixed-point water spraying cooling range, thereby improving the cooling effect.

[0028] When the present embodiment is used, the fixing seat 1 is first installed and fixed on the rotating support arm of the mud gun body, and the sliding rail 2 is adjusted to a position parallel to the top of the mud gun. Then the tool is connected to an external power supply and tested to see if it is normal. Then the water injection pipe 17 is connected to an external water pipe to connect cold water. When normal use is required, the rotating mud gun blocks the iron outlet, and the high-temperature molten iron will be conducted to the gun body, thereby increasing the temperature of the gun body. At this time, the water injection pipe 17 continuously inlets water and enters the interior of the rectangular tube 10 through the water inlet hose 14. At this time, water is continuously sprayed through the flat nozzle 12 to wet and cool the high-temperature gun body at the bottom. After cooling, in order to expand the cooling effect, cold water will be sprayed from the high-pressure nozzle 16 inside the arc tube 13, and the telescopic cylinder 19 is used to drive the arc tube 13 to swing continuously left and right, thereby swinging the cold water in an arc shape, expanding the cooling range, and improving the cooling effect.
