Abstract
Description
Technical Field
[0001] The utility model relates to a device for dealing with ash hopper blockage under an incinerator grate, in particular to an auxiliary ash discharging device. Background Technique
[0002] Due to the high ash content in the garbage composition, a large amount of ash and slag will leak into the ash hopper under the grate through the gaps of the incinerator grate during the operation of the incinerator grate, and then enter the slag pond or slag scraper through the action of the ash leakage conveyor at the bottom of the furnace. During the actual operation, since the ash leakage is easy to caking on the water seal line of the ash leakage conveyor at the bottom of the furnace, resulting in the ash and slag not being able to enter the conveyor in time, and finally it is easy to cause ash hopper blockage. The current common methods for cleaning ash hopper blockage are mostly to open the manhole door of the ash hopper under the grate, discharge the blocked ash and slag, and use fire water to wash the ash and slag into the slag scraper and slag pond. However, since the ash and slag have a high temperature and a large amount of dust is generated when discharged, this is likely to cause injuries to maintenance personnel and will greatly affect the clean and civilized production work in the boiler workshop. Therefore, it is crucial to design an auxiliary device to solve this problem. Content of the Utility Model
