Embodiment 1

[0030] Combine below figure 1 Provide a clear and complete description of the technical solution of the present invention.

[0031] The upper part of the slag well 1 is connected to the slag outlet of the last stage of the incinerator, and the bottom is connected to the entrance of the inner chamber 4 of the slag extractor. A wear-resistant plate 2 is arranged on the outer surface of the thermal insulation material inside the slag well 1. There are expansion joints between the wear-resistant plates, which can better protect the insulation material and prevent it from falling off under force. The bottom edge of two slag drop baffles 3 is arranged on the inner surface of the slag well 1 and is arranged on the upper and lower walls of the slag well. The slag drop baffles 3 are all inclined downward at 45°. Slow down the falling speed of the slag, reduce the impact on the slag 6 at the bottom of the slag extractor, prevent its agglomeration and hardening, and hinder the movement ...

Embodiment 2

[0034] Same as embodiment 1, except that the downward inclination angle of the slag drop baffle 3 of the present invention is 40°, and the angle between the arm body of the slag pushing arm 8 and the horizontal plane is 40°.

Embodiment 3

[0036] Same as embodiment 1, except that the downward inclination angle of the slag drop baffle plate 3 of the present invention is 50°, and the angle between the body of the slag pushing arm 8 and the horizontal plane is 30°.

Abstract

The invention relates to a slag discharging device of a garbage incinerator. The slag discharging device is suitable for a garbage incineration plant. A furnace slag dropping baffle and an anti-abrasion plate are disposed in a slag falling well; the head of a slag push arm outside an inner cavity of a slag discharging machine penetrates through the near-bottom position of the inner cavity of the slag discharging machine to be directly inserted into the inner cavity; a sludge removing apparatus, an automatic water supplement apparatus and a compressed air spray-blowing pipe are further disposedbehind a slag push arm; and a maintenance clearing door is disposed on the side surface of the bottom of the slag discharging machine. The slag discharging device runs safely and stably, a moisturizing material in the slag falling well is safe and does not fall off, the bottom of the slag discharging machine is not hardened and agglomerated, the slag push arm runs smoothly along the way without furnace slag sludge agglomeration, and the number of times of failure machine halt is reduced.

Description

technical field [0001] The invention relates to the technical field of garbage incinerators, in particular to a slagging device for garbage incinerators. Background technique [0002] With the rapid development of my country's economy and the improvement of material level, "garbage siege" is a difficult problem faced by most domestic cities. If it is not disposed of effectively, it will cause serious pollution to the environment. At present, landfill is the main method of waste disposal, but it has the disadvantages of occupying a large area, difficult to treat leachate, and secondary pollution of the surrounding environment. Waste incineration power generation has become the mainstream choice for urban waste treatment due to its characteristics of "reduction, resource utilization, and harmlessness". Most of the existing waste incinerators are mechanical grate furnaces, and the slagging device is an important part of them. [0003] At present, most of the slag discharge de...
