At present, the garbage treatment mode is mainly landfill, but the garbage treatment mode has the defects of large occupied area, difficult treatment of leachate, secondary pollution to the surrounding environment and the like. The characteristics of reduction, resource utilization and harmlessness of the waste incineration power generation become the mainstream choice for urban waste treatment at present. Most of the existing garbage incinerators are mechanical grate furnaces, and a slag discharging device is an important component of the mechanical grate furnaces.
At present, most slag discharging devices are long in slag falling well channels, and the falling process of slag can smash surrounding heat insulation materials to cause the falling of the slag falling wells. And the slag well lower part links to each other with the inside cavity of mucking machine, and the slag falls to the mucking machine bottom from the slag well upper portion that falls, can tamp the existing slag in bottom, causes its sclerosis caking, leads to pushing away the unsmooth even stop of slag arm motion. In addition, when the slag pushing arm does reciprocating motion under the action of the hydraulic cylinder, part of slag sludge permeates into the rear part of the slag pushing arm through the gap between the slag pushing arm and the wear-resisting plate at the bottom of the slag discharging machine. Slag silt can deposit the caking, and long-time unclean can lead to the inside water yield of mucking machine to reduce, hinders to push away the sediment arm action. In order to cool the slag and prevent the diffusion of the smoke in the incinerator, the bottom of the slag extractor needs to be sealed by water, so that the control of the water level is very important. In the field inspection, most of workers need to climb to the upper part of the water tank of the slag extractor to inspect the water level, the working environment is severe, and the movement is inconvenient.
In order to solve the problems, the structure of the slag discharging device is optimized, so that the slag discharging device can be safely, economically and stably operated, and the times of fault shutdown are reduced.

The falling baffle plate is made of wear-resisting plates, and the falling baffle plate is obliquely hung on the inner surface of the falling slag well.
The downward inclination angle of the slag falling baffle is 40-50 ℃.
The angle between the arm body of the slag pushing arm and the horizontal plane is 30-40 ℃.
The outlet of the blowing pipe is provided with a filter screen.
Wear-resisting plates are arranged at the sharp turning position, the bottom and the head of the slag pushing arm of the inner cavity of the slag extractor vice-jaw slag extractor.
Compared with the prior art, the invention has the beneficial effects that: the heat insulation material in the slag falling well is well protected, the service life is prolonged, and the subsequent maintenance work is reduced. In addition, the impact on the slag at the bottom of the slag extractor is greatly reduced due to the increase of the falling baffle of the slag, the hardening and caking of the slag are avoided, and the force of pushing the slag arm is reduced. The arrangement of the compressed air device increases the disturbance of slag sludge at the rear part of the slag pushing arm and reduces the possibility of deposition and agglomeration. The arrangement of the slag circulating pipeline realizes the on-line automatic cleaning of slag sludge at the rear part of the slag pushing arm, and the labor time cost is saved. The arrangement of the automatic water replenishing device and the water level meter facilitates better control of the water level of the slag discharging machine by operating staff, and the safe operation of the slag discharging machine is ensured.
