Charging apparatus and method for charcoal

The present invention relates to a charcoal cooling device and a method thereof, and more particularly, hot charcoal is mixed with cold air, sucked, and then transported through a cooling conduit to reduce the time required for cooling the charcoal by forcibly cooling the charcoal. The present invention relates to a charcoal cooling apparatus and a method for enabling automatic feeding while maintaining a constant amount of charcoal supplied to a bag by a metered feeding device, while reducing the time taken from manufacturing to packaging. .

In general, farming soils can be harvested and then fire-fighted to maintain the most ideal soil conditions. Today's farmland destroys the environment in which microorganisms can live due to overuse of chemical fertilizers and pesticides. By creating an environment where pathogenic bacteria, such as Husarium, can live, these pathogenic bacteria occupy a considerable amount (about 25% or more) compared to all bacteria, and the decayed soil created by such pollution is currently about 95% or more. Is nearing.

The decayed soil is difficult to expect a very large effect due to the decaying bacteria even when the organic fertilizer is supplied, activated carbon farming method that can reduce the soil in the near future.

Charcoal used in the activated carbon farming method is known to be effective in improving soil and crop growth because it reduces the density of effective microorganisms and provides a low density of decaying microorganisms.

In addition, the charcoal used in organic farming uses charcoal made from sawdust or chaff which is relatively inexpensive than charcoal made by burning wood and does not need to be crushed. It cooled in the state left to natural until it fell below a fixed temperature.

That is, patent application No. 1996-034567 (name; chaff Huntan automatic manufacturing device), utility model registration No. 20-1997-0005714 (name: chaff Huntan automatic manufacturing device capable of mass production), utility model As disclosed in Korean Patent Application No. 20-1997-0017752 (name: chaff Huntan manufacturing equipment), the rice husk is burned slowly in the Huntan tank, and then the air for combustion is shut off or an inert gas such as nitrogen gas is introduced into the Huntan Tank. It was designed to be injected and burned, but the charcoal (Hun charcoal) made through this process has a considerable amount of latent heat so that it can be packaged only after cooling for a long time.

In this way, when the charcoal is left in a natural state of cooling, the charcoal exposed to the surface cools relatively quickly, but it takes a lot of time because the charcoal inside is not easily cooled by the warming effect unless it is turned over. This is to cool the charcoal. There was a problem that requires a large space or facility, and had a problem of lowering productivity by greatly extending the time required from manufacturing to packaging.

On the other hand, conventionally, when packing charcoal, the bag is placed on the scale, the charcoal is packed while looking at the scale of the scale, or the bag is placed on the bag depending on the human eye. There was a problem to improve the productivity, because there was a manual packaging depending on the manpower.

The present invention has been made to solve the above problems, an object of the present invention is to provide a charcoal cooling apparatus and method that can more quickly cool the charcoal, can be quantitatively supplied to the bag.

In order to achieve the object of the present invention, the supply hopper for supplying carbonized charcoal, and the char input into the supply hopper together with the air sucked through the air inlet to the storage tank and the char in contact with the air during the transfer. And an air inlet having a cooling pipe line for cooling the gas and an air inlet formed in the cooling pipe line to suck the char in the supply hopper together with the air, transport it through the cooling pipe line, and discharge the sucked air. Installed in the distal end of the cooling pipe to separate the char and air mixed with each other, the heated air is discharged into the atmosphere through the air discharge pipe, the cooled char is cyclone to collect into the storage tank, and the char is separated from the cyclone As a storage tank for storing water and a fixed quantity supply mechanism for discharging fixed quantity of charcoal stored in the storage tank Castle the char cooling device is provided.
