Gun head damage emergency plug of hydraulic clay gun

Abstract

The invention discloses a gun head damage emergency plug of a hydraulic clay gun. The gun head damage emergency plug of the hydraulic clay gun comprises a hydraulic clay gun body, a common gun head, an emergency gun head, flanges and an emergency plug device. The common gun head is arranged on the left side of the hydraulic clay gun body. The emergency gun head is arranged above the common gun head. The emergency plug device is arranged between the common gun head and the emergency gun head. The emergency plug device comprises a handle, a piston, a steering plate, a steering rod, a sleeve, a sliding plate, sliding grooves, a reset spring, a bearing and sliding blocks. The gun head damage emergency plug of the hydraulic clay gun is simple in structure and convenient to use, under emergencyconditions, the potential hazards that since the front edge of the gun head is damaged, clay exudes from the plugged gun and the gun cannot be plugged can be eliminated, the phenomenon that since a tap hole cannot be plugged, the control of greatly reducing blast and oxygen is forced to be conducted is avoided, and blast furnace production can be smoothly conducted; besides, the piston is firmly fixed, the phenomenon that the piston is loose since the air pressure in a hydraulic cavity changes is avoided, and the quality and size of the manufactured gun clay cannot change.

Description

technical field [0001] The invention relates to the field of equipment in front of the furnace, in particular to an emergency plug for damage to the head of a hydraulic mud gun. Background technique [0002] Blast furnace production is closely linked, and the quality of each operation will directly or indirectly affect blast furnace production. The function of the hydraulic mud gun is to quickly and accurately block the taphole after the iron is placed, so that the blast furnace can quickly enter the next cycle of operation. Failure to block the gun in front of the furnace is one of the biggest production accidents in front of the furnace. Once the gun cannot be blocked at the end of the iron gate, the splashed slag and iron will seriously affect the workers in front of the furnace to deal with the accident. The iron gate area The equipment is easy to be burned, the personnel are prone to burn injury, and the smoke formed by the spray will cause dust and deteriorate the env...

AI Technical Summary

Problems solved by technology

However, at the end of the iron opening, it is often accompanied by the filling of the iron cans. Once the iron cans are not turned over in time, the iron cans are not properly distributed, and vicious accidents such as iron dropping to the ground follow, which have a great impact on the production of blast furnaces.

[0003] The front surface of the gun head of the mud gun should be flat and smooth. Once there is a gap in the gun head, it will block the gun and emit mud and affect the working state of the iron mouth, and cause the gun head to burn out and the mud gun will not be able to block the gun.

When there is a defect in the gun head or the gun head is damaged due to improper operation when the gun is blocked, it takes at least 10-20 minutes to replace the gun head, and the splashing of the iron mouth and the condition of the iron tank are often not allowed. Sufficient time to replace the gun head, which will directly affect the work of the blast furnace

The above problems are not solved. China Patent Network Authorized Notice No. CN 204198769 U has designed an emergency plug for damage to the head of the hydraulic mud gun, but the piston of the device is not fixed enough, and the piston will loosen due to the change of air pressure in the hydraulic mud gun cavity during use. At the same time, the device realizes new foam through the through hole on the piston, and the size and quality of the foam produced will be different from the size and quality of the foam produced by the original nozzle.
