The air integration pipe is installed in the longitudinal direction of the water tank and the air injection pipe 56 is installed in the width direction of the water tank so that the injected air is delivered to the end of the air injection pipe. This is because, when the air inlet pipe is arranged in the longitudinal direction of the tank, the air supplied from the air integrating pipe is weakly supplied to the end of the air inlet pipe and thus cannot be supplied well.

In the air integration pipe, the air injection pipe is installed in a plurality of branches are arranged in the inner lower portion of the tank. Air inlet pipe is provided with an air regulator 58 for adjusting the amount of air injected and the air pressure, respectively. The connection portion between the air integration pipe and the air injection pipe is preferably installed to be exposed to the outside of the water tank, and the air regulator is preferably installed on the exposed air injection pipe. Naturally, the air injection pipe installed inside the tank has heat, pressure, and chemical durability.

A plurality of air injection nozzles 57 are formed on the upper side of the air inlet pipe so that air is injected between the grains of the patterned wood board being dyed, so that the wood boards are not evenly attached to each grain but evenly dyed for each part. As the air injection nozzle is formed into a fine hole, the injection function is maximized. The more air injection pipes and air injection nozzles are installed at regular intervals, the more the purpose of injecting air into the grain of wood veneer is maximized.

Looking at the action of the pattern wood board dyeing apparatus according to the present invention made as described above are as follows.

The patterned wood board dyeing apparatus according to the present invention is a device for dyeing by dipping a wood board in a water tank, the dye, water and medicine are supplied to the stirring section and stirred. The stirred dye, water and chemicals are circulated while being supplied to the water bath by the circulation portion. The dye, water and chemicals circulated are circulated while receiving steam by the heat exchanger and undergoing a heat exchange process. Dye, water, and chemicals are supplied to the tank, and the air is injected from the air inlet in the state that the patterned wood board is immersed in the tank. When pressure is applied inside the tank by the air pressure tank, the wood veneer improves dye permeability.

In more detail, the dye, water and chemicals are evenly stirred by the stirring blades when supplied to the stirring vessel. At this time, the stirring process is further activated by the steam of the steam line. The stirred dye, water and chemicals are supplied to the circulation section by the feed pump and circulated. At this time, the direction of movement of the dye, water and chemicals stirred by the non-return valve does not flow backward.

The stirred dye, water and chemicals are transferred to the circulation pump tube and forcedly circulated by the circulation pump. Circulating dyes, water and chemicals are circulated and supplied to the upper side of the tank through the circulation pipe. Dye, water and chemicals supplied to the tank are temporarily circulated in the tank and then circulated through the circulation pipe and the circulating pump pipe heat exchanger by the circulation pump. The circulating dyes, water and chemicals go through a series of processes that are fed back into the tank.

Dye, water and chemicals passing through the heat exchanger are heat exchanged through the heat exchanger tube. The steam is introduced into the heat exchange body through the steam inlet pipe, and then heat is supplied to the heat exchanger pipe and then discharged to the steam discharge pipe. The amount and supply of steam are controlled by the solenoid valve, and the solenoid valve controls the amount and timing of the steam in the heat exchanger according to the temperature of the dye, water and chemicals supplied into the tank by the temperature sensor mounted inside the tank. The steam is not flowed back by the non-return valve, only in the inlet direction.

Meanwhile, air is injected from the bottom of the tank to the top by the air injection unit. The wind generated by the wind generator is transferred to the air integrator by the air transport tube. At this time, the air delivery pipe is branched into a plurality of pipes and is delivered to the air of uniform pressure. The delivered air is integrated in the air inlet tube and split into the air inlet tube. The air moved to the air injection pipe injects air to the upper side of the tank through the air injection nozzle. Air inlet and air pressure are controlled by air regulator installed in each air inlet pipe.

At this time, the air injection part and the air pressure tank are applied differently and dyed according to the thickness of wood veneer. When the thickness of the wood veneer is 0.1 to 0.2 mm or less, the air is injected to the bottom of the tank through the air injection portion, and when the thickness of the wood veneer is 0.2 to 2 mm or less, the air pressure is applied to the inside of the water tank through the air pressure tank. In the case of using an air pressure tank, the air inlet unit is closed to prevent the air pressure from being released by the air injection nozzle by closing the air regulator without injecting air to the bottom of the tank.

Briefly, the process of dyeing the patterned wood board by soaking the pattern wood board with the dye, water and chemicals supplied to the tank.

The dyeing process consists of ordering, bleaching, washing, neutralizing and dyeing.

Refining is a pretreatment process that removes impurities from wood veneer. At this time, the chemicals of the refining process are hydrogen oxide (H ₂ O ₂ ), sodium hydroxide (NaOH) and the like.

Bleaching is the process of discoloring the original color before dyeing the wood veneer. At this time, the additives of the bleaching process are surfactant (A510), fruit stabilizer (STB) and the like.

Water washing is the process of removing the chemicals used to refine and bleach from the tank. At this time, the wash water is supplied to the water tank by the washing water supply valve, and the washing water is discharged by the washing water discharge valve. In washing, the washing water is water.

Neutralization is the process of neutralizing the chemicals remaining in the washed tank by washing with water. Chemicals in the neutralization process are water, CH ₃ C00H, and super-neutralizing agents.

The neutralized water tank is dyed with a patterned wood board through a dye for dyeing.
