A pencil board carbonization device

Abstract

The invention discloses a pencil board carbonization device, which includes a carbonization furnace and a blast furnace. The blast furnace includes a first support frame, a belt, a motor, a reducer and a furnace body. The furnace body includes an outer furnace and an inner furnace. A first connecting pipe and a second connecting pipe are provided respectively, the first connecting pipe and the second connecting pipe communicate with the interior of the inner furnace, the first connecting pipe is coaxially fitted with a first pulley, the speed reducer has a second pulley, and the first The pulley and the second pulley are connected by a belt. The inner furnace has a plurality of rectangular grooves sunken into the furnace on the peripheral wall. The first connecting pipe and the second connecting pipe pass through the two ends of the outer furnace. The second connecting pipe and the outer furnace A second bearing is arranged therebetween to realize the relative rotation between the second connecting pipe and the outer furnace. The outer furnace is placed on the first supporting frame, and one side of the outer furnace is provided with a first opening and a second opening. Compared with the prior art, the invention can realize the uniform carbonization of the pencil board and effectively improve the carbonization quality of the pencil board.

Description

technical field [0001] The invention relates to the field of pencil processing devices, in particular to a pencil board carbonization device. Background technique [0002] Pencil is a special type of pen used for writing and drawing sketches. During the production process of pencils, the surface of the pencil board needs to be carbonized to achieve the purpose of removing moisture in the pencil board and destroying the nutrients inside the pencil board. It achieves good anti-corrosion and insect-proof effects, and because its water-absorbing tissue fibers are reorganized, its physical properties are more stable, not only prolonging the service life, but also not easy to deform and absorb water, and the surface of the carbonized pencil board is as silky as polished The texture is smooth and full, the color is warm, the texture is prominent, and it is extremely natural and beautiful; the drying and carbonization method of the pencil board commonly used in the market is to put ...

[0002] Pencil is a special type of pen used for writing and drawing sketches. During the production process of pencils, the surface of the pencil board needs to be carbonized to achieve the purpose of removing moisture in the pencil board and destroying the nutrients inside the pencil board. It achieves good anti-corrosion and insect-proof effects, and because its water-absorbing tissue fibers are reorganized, its physical properties are more stable, not only prolonging the service life, but also not easy to deform and absorb water, and the surface of the carbonized pencil board is as silky as polished The texture is smooth and full, the color is warm, the texture is prominent, and it is extremely natural and beautiful; the drying and carbonization method of the pencil board commonly used in the market is to put the pencil board to be dried and carbonized into an iron tank, and then heat it under the tank Start the fire, then start the motor that drives the tank to turn the tank over, so as to drive the pencil board in the tank to turn over and fry. After drying and frying for a period of time, continue to heat the iron tank to carbonize the surface of the pencil board, and then achieve As for the carbonization effect on the surface of the pencil board, since the carbonization method of the pencil board is carried out by directly burning the iron tank body with firewood, it not only consumes a lot of energy, but also the heat of combustion is not concentrated, resulting in some areas of the iron tank body temperature Too high, and the temperature in some areas is not enough to reach the carbonization temperature, so the quality of the carbonized pencil board is unstable and the defective rate is high
