Detailed Description

The technical solution of the present invention will be described below with reference to the accompanying drawings and examples.

As shown in fig. 1 to 4, the energy-saving slag discharging device of the present invention is installed at a slag discharging port of a pulverized coal combustion furnace 1, and includes a discharging pipe 2 and a frame 3 penetrating vertically, the discharging pipe 2 is a square pipe, the discharging pipe 2 is butted with and located below the slag discharging port of the pulverized coal combustion furnace 1, an upper sealing cover 6 controlled to be opened by an upper cylinder 4 is provided at an upper portion of the discharging pipe 2, a lower sealing cover 7 controlled to be opened by a lower cylinder 5 is provided at a lower portion of the discharging pipe 2, the upper sealing cover 6 and the lower sealing cover 7 both extend into the discharging pipe 2 in a horizontal direction to seal the discharging pipe 2, the upper cylinder 4, the lower cylinder 5 and the discharging pipe 2 are all installed on the frame 3, because the stroke of the upper cylinder 4 and the lower cylinder 5 is relatively large, in this embodiment, the cylinder stroke is 650mm, in order to ensure the levelness of the extended cylinder, a platform 31 can be arranged on the frame 3, the tail end of the piston rod of the air cylinder is provided with a roller 8 for supporting, and the roller 8 rolls on the platform 31, so that the upper sealing cover 6 and the lower sealing cover 7 can be ensured to move along the horizontal direction, and the upper sealing cover 6 and the lower sealing cover 7 have the same shape.
