Description

Technical Field

[0001] The utility model relates to the technical field of wire feeding machines, in particular to a device for preventing a wire feeding machine conduit from being blocked. Background Art

[0002] Calcium treatment is currently one of the main means of refining molten steel outside the furnace. Calcium treatment is the process of extracting the calcium wire from the wire frame through the wire feeder, passing it through the wire feeder conduit, and feeding the calcium wire into the molten steel at high speed. The wire feeder conduit currently used is a simple stainless steel pipe. When feeding the wire, the splashing slag is easy to stick to the inner wall of the conduit, causing the conduit to be blocked. In addition, the wire feeder conduit is 20cm-50cm away from the steel liquid surface. During calcium treatment, the calcium wire needs to penetrate the slag layer first and then enter the molten steel. The calcium recovery rate is low, and the bottom of the conduit close to the molten steel is easily burned by high temperature, resulting in frequent replacement of the wire feeder conduit, increasing costs and manpower consumption.

[0020] like Figure 1 As shown, the device for preventing the wire feeding machine conduit from being blocked in this embodiment includes an air source 1, a ventilation hose 2, a U-shaped three-way pipe 3, a metal hose 4 and a hollow steel pipe 5. The cross section of the hollow steel pipe 5 is semi-U-shaped, and two hollow steel pipes 5 are fixedly connected to the bottom sides of the wire feeding conduit. Preferably, the hollow steel pipe 5 is fixedly connected at 5cm-10cm away from the outlet of the bottom end of the wire feeding conduit, and a plurality of air outlets are correspondingly opened on the inner walls of the two hollow steel pipes 5, and the direction of the air outlet is set to be inclined downward to discharge air, and the top of each hollow steel pipe 5 is connected to a branch pipe and the bottom end is blocked. At this time, the U-shaped three-way pipe 3 includes an inlet end and two outlet ends, and the two metal hoses 4 are respectively connected to the branch pipe at one end and connected to the outlet end of the U-shaped three-way pipe 3 at the other end, so as to realize the connection between the U-shaped three-way pipe 3 and the hollow steel pipe 5, and the inlet end of the U-shaped three-way pipe 3 is connected to the air source 1 through the ventilation hose 2, so as to realize the connection between the U-shaped three-way pipe 3 and the air source 1.
