Description

TRANSFER SYSTEM FOR INJECTION OF WOOD CHIP TO BOILER {TRANSFER SYSTEM FOR INJECTING WOOD CHIP WITH BOILER}

The present invention relates to a transfer system for injecting wood chips into a boiler. Specifically, wood chips supplied from an import hopper are separated from foreign materials and oversized wood through a disk screen to remove wood chips having a predetermined size or less from which foreign materials are removed. The present invention relates to a transfer system for injecting wood chips into a boiler, which is stored evenly in a bunker and then fed into the boiler using a screw feeder, a belt scale and a bucket elevator.

As part of carbon neutrality to reduce carbon dioxide emissions, boilers using wood as a fuel are gradually increasing.

Such a boiler is supplied with a certain amount of wood chips by a transport system for transporting wood chips. As shown in FIG. 1, the transport system 10 includes a feeder 11, a first belt conveyor 12, 2-belt conveyor 13, magnetic separator 14, third belt conveyor 15, separator 16, fourth belt conveyor 17, apron conveyor 18, reversible conveyor 19 ), A feeder 20, and a boiler 21.

First, the feeder 11 supplies wood chips in a yard state.

Then, the first belt conveyor 12 and the second belt conveyor 13 transfers the wood chips supplied from the feeder 11.

In addition, the magnetic separator 14 magnetically sorts the metal contained in the wood chips fed from the second belt conveyor (13).

In addition, the third belt conveyor 15 transfers the wood chips from which the metal discharged from the magnetic separator 14 is removed.

On the other hand, the foreign matter sorter 16 removes foreign matters of a predetermined size or more, such as waste contained in the wood chips introduced from the third belt conveyor 15.

The fourth belt conveyor 17 and the apron conveyor 18 transfer wood chips discharged from the separator 16.

In addition, the reversible conveyor 19 uniformly distributes the wood chips conveyed from the apron conveyor 18 while the forward and reverse rotation.

In addition, the feed bin 20 is discharged after loading the wood chip falling from the reversible conveyor 19 to the inlet. At this time, the feed bin 20 is provided with a vibrator 20a to generate a vibration on the side to drop the wood chip in the downward direction.

In addition, the boiler B generates heat by burning wood chips falling from the feed bin 20 to the inlet.

However, such a conventional transport system causes foreign matter (stone, soil, sand), moisture, oversized wood, etc. to be mixed in the wood chip supply process, causing obstacles during the operation of the equipment, and supplying the wood chips using only the feeder. Therefore, there is a problem that the supply amount of the wood chip is not constant.

The present invention is to solve the above problems, by separating the wood chips supplied from the hopper through the disk screen foreign matter and oversized wood to store the wood chips below a certain size evenly removed in the bunker even after The purpose is to provide a transfer system for injecting wood chips into the boiler to operate the equipment stably by using a screw feeder, a belt scale and a bucket elevator.
