AI Technical Summary
Traditional boiler coal-feeding equipment is prone to coal powder sticking problems when the water content in the coal is high, and the screening process is usually carried out before it is sent to the furnace, which adds an additional step.
A rapid separation type boiler coal loader was designed. Screening was achieved on a conveyor belt, and a sieve plate and a hot air box were set in the hopper. Hot air was used to remove moisture from the coal blocks, while the sieve plate moved back and forth in the hopper to perform screening.
The coarseness and fineness of the coal blocks can be screened while the coal is being loaded, thereby preventing the coal powder from sticking together, simplifying the process and improving the efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of boiler coal loading, in particular to a quick separation type boiler coal loading machine. Background Art
[0002] Boilers are energy conversion devices. Energy input to the boiler includes chemical energy from the fuel and electrical energy, and the boiler outputs a certain amount of thermal energy in the form of steam, high-temperature water, or an organic heat carrier. Previously, boilers were fed coal using gate-type feeders, but these are now largely obsolete. The newly developed forward-rotating chain boiler feeder allows coal from the coal bunker to pass through a coal-bed gate and onto a comb-shaped screen. After screening, the coal is separated into appropriate layers on the grate according to size and coarseness, improving combustion conditions in the furnace.
[0003] However, when the coal contains moisture, the traditional screener can easily cause coal powder to stick to the comb screen, and the screen needs to be cleaned during operation, which is not practical. Moreover, most screening is basically carried out before sending the coal to the furnace, which adds an extra process. Utility Model Content
