Description

DETAILED DESCRIPTION OF THE INVENTION I. Object of the Invention (1) Field of Industrial Application The present invention relates to a water-sealed charcoal baking oven.

(2) Conventional technology Conventionally, in the case of producing charcoal, a charcoal kiln was constructed from clay or stone in the mountains where the raw oak, oak, etc. are naturally growing, and the oak cut into a predetermined length Charcoal is manufactured in about 3 to 4 days after the raw materials such as wood and oak are packed in a charcoal kiln and the raw materials are ignited and burned. Therefore, charcoal can be manufactured only in charcoal kilns built in the mountains or in the suburbs, and the number of charcoal kilns has been reduced due to the decrease in demand for charcoal in recent years. On the other hand, due to the sluggish demand for wood chips in recent years, a large number of factories, such as sawmills and bark, have accumulated and left a large amount of waste wood and bark, and are confused about the treatment.

(3) Problems to be solved by the invention However, even if an attempt is made to produce charcoal by effectively utilizing waste wood, bark, etc. accumulated and left in the lumber factory, etc.
The transportation cost to the site in the mountains tends to be high, and therefore, a charcoal kiln that can easily produce charcoal from raw materials such as waste wood and bark has been desired in sawmills.

The present invention has been made in view of the above conventional problems, and an object thereof is a metal can body having upper and lower ends opened,
By providing an upper and lower receiving groove at the joint with the upper and lower lids that open and close the upper and lower openings of this can body and water sealing, it is easy to put raw materials into the can body and take out charcoal charcoal carbonized in the can body,
An object of the present invention is to provide a water-sealed charcoal baking oven characterized in that efficient charcoal-burning can be performed by water-sealing operation and opening operation of the upper and lower openings of the can body, and that the structure is simple and the manufacturing cost is low.

II. Structure of the Invention (1) Means for Solving the Problems In order to achieve the above object, the upper opening 14 and the lower opening 14
And a hollow can body 16 provided upright and downward. The hollow can body 16 has an upper lid 18 and a lower lid 20 for opening and closing the upper and lower openings 14 and 14, respectively. On the periphery of the lid 20,
Lower receiving groove 34b for receiving the edge portion of the lower opening 14 of the can body 16.
The upper opening 14 of the can 16 is provided with an upper receiving groove 34a for receiving a reinforcing flange 18a fixed downward to the peripheral edge of the upper lid 18, and the upper and lower portions of the lower and upper portions are provided. The receiving grooves 34a, 34b are filled with water at a required water level to seal the edges of the upper and lower openings 14, 14 of the can body 16, and the upper and lower lids 18, 20 are used for the upper and lower receiving grooves. In cooperation with the grooves 34a, 34b, it is composed of a water-sealed charcoal baking oven 10 which is pivotally attached to the can body 16 so as to be openable and closable so that the water-sealed state and the lid opened state can be selectively obtained. .

(2) Action When producing charcoal in the water-sealed charcoal kiln of the present invention, with the lower end opening of the can closed with the lower lid, the upper lid is opened to remove wood chips, backboard, bark, etc. Put the raw material into the can. After that, the upper lid is closed, and water is supplied into the upper receiving groove of the upper opening edge of the can to seal the joint between the upper end of the body of the can and the upper lid.

Next, the raw material is ignited through the cooking port, and when the raw material in the can begins to burn, the cooking port is closed. The ignited raw material is burned by supplying air from the lower opening edge of the can, the lower receiving groove at the peripheral edge of the lower lid, and the joint, and the white smoke is discharged from the chimney of the upper lid.
Over time, the smoke gradually turns into bluish, anti-transparent smoke. At this point, water is supplied into the lower receiving groove of the lower lid to seal the inside by sealing the joint between the can body and the lower lid with water.

As a result, the supply of air to the inside of the can is shut off, the burning raw material is extinguished, and the internal raw material is carbonized in a smoldering form to become charcoal. After the inside of the can completely dissipates heat, the lower lid is opened and carbonized charcoal is taken out.

Therefore, it is possible to easily put the raw material into the can body and take out the carbonized charcoal, and to perform efficient charcoal baking by the water sealing operation and opening operation of the upper and lower openings of the can body, and the joining of the hollow can body and the upper and lower lids. With a simple structure in which a receiving groove is provided in the part, the manufacturing cost can be grounded at low cost, and charcoal can be manufactured by using vacant land in the factory using waste wood, bark, etc. discharged from a sawmill as raw material.
