Garbage grab overhead cranes in municipal solid waste incineration plant is the core equipment of the garbage feeding system of various garbage incineration power plants in modern cities. It is located above the garbage storage pit and is mainly responsible for the operations of feeding, handling, mixing, picking and weighing the garbage.
Purpose:
1.Feeding
When the garbage at the feed inlet of the incinerator is insufficient, the crane grabs the fermented garbage in the garbage pit and runs to the top of the feed inlet to feed the feed hopper of the garbage incinerator.
2.Handing
Transport the garbage near the discharge gate to other places in the storage pit to avoid congestion of the discharge gate, adjust the amount of garbage in the pit, and store it for 3 to 5 days of garbage incineration.
3.Mixing
Due to the high water content and low combustion value of domestic garbage, the garbage needs to stay in the storage pit for a certain period of time. Through natural compression and partial fermentation, the water content is reduced and the calorific value is increased. The mixing of new and old garbage can shorten the fermentation time. In addition, due to the complex composition of domestic waste and the large change in composition content, in order to avoid excessive fluctuations in the nature of the waste entering the furnace, it is also necessary to stir and mix the waste in the pit.
4.Picking
The objects that have been accidentally entered into the storage pit, but not suitable for incineration, will be taken out.
5.Weighting
In order to count the actual amount of waste incineration, the waste is weighed and measured before the waste is put into the inlet of the incinerator.
