Description

Technical Field

[0001] The utility model relates to the technical field of mud gun machine maintenance, and more specifically, to a tool for facilitating the removal of a gun nozzle latch of a mud gun machine. Background Art

[0002] Existing blast furnaces generally use two tapholes to tap iron in turn. Each time the taphole is finished tapping iron, a mud gun machine is needed to block the taphole. During the blocking process of the mud gun machine, the gun mouth will be burned by the slag iron water sprayed from the taphole. Within a certain period of use, the gun mouth is severely burned and needs to be replaced. The disassembly of the gun mouth latch of the mud gun machine is generally done by manually pulling out the latch for replacement. However, each time the mud gun machine blocks the taphole, the gun mud in the mud gun machine is baked at high temperature, and a small amount of tar will be strung into the mud gun mouth latch, making it difficult to remove the gun mouth latch. Each operation takes too long, increasing the time and labor intensity of the operator. In order to improve efficiency and reduce intensity, a round steel or a cross screwdriver can be used to align the latch, and then a sledgehammer can be used to hit the round steel or cross screwdriver to push the latch out. However, this way of hitting makes it difficult for the round steel or cross screwdriver to locate and it is easy to hit your hand.

[0003] Therefore, it is urgent to design a tool that is convenient for removing the muzzle latch of a mud cannon machine to solve the above-mentioned problems. Utility Model Content
