Working principle of toothed roller unloader
The EGXM2 shaft furnace toothed roller unloader is composed of a transmission device, a sealing device, a cooling device, a lubrication system, and a hydraulic power device system.
1. Working principle of toothed roller
Under the push of the oil cylinder, the swing rod installed at the transmission end of the toothed roller rotates 36 degrees around the center of the toothed roller. The swing rod is equipped with two claws to push the ratchet wheel installed on the toothed roller. The swing rod rotates 10 times to complete the 360 degree rotation of the toothed roller.
2. Sealing device
Each toothed roller is composed of a sealing flange, a sealing box, and a packing gland. The sealing cavity structure is cooled by water to prevent aging of the packing and affect the sealing. Turning the gland screw can adjust the tightness of the packing, and there is a lubricating oil circuit between the packing, improving the sealing effect.
3. Toothed roller
There are ten raised edges and corners on the toothed roller, and four ring ribs form the surface of the toothed roller. The inner cavity has raised reinforcing ribs, bearing supports at both ends, and rotating joints are installed at both ends of the roller to control the water level of the curved water pipe. It is mandatory to keep the inner cavity of the toothed roller in a fully filled state.
