Wood bleaching device

Abstract

The invention discloses a wood product bleaching device, which has the key technical points that: the device comprises a nozzle which is connected with an uptake pipe, and the top of the uptake pipe is connected with a retort which is higher than the nozzle and can make the nozzle produce a pressure high enough for injection; and the retort is open and contains a bleaching agent. The invention provides a wood product bleaching device which is safe, reliable, simple in structure, low in cost, aiming to overcome the drawback that the prior wood product bleaching device lacks safety.

Description

Technical field

[0001] The invention relates to a bleaching device for wood products.

Background technique

[0002] This product should be bleached during the manufacturing process of wood furniture, because some parts of the original wood product may be darker, covering the original wood grain of the wood product, and there is a large amount of relative color difference between the grains of different parts of the wood product, which affects it. After surface treatment with bleaching agent, wood products with uniform color and fine texture can be obtained, and the original wood grain is also fully reflected.

[0003] There are generally two bleaching methods for wood products. One is to apply bleach on the wood surface. This method will cause a lot of waste of bleach, and the brushing is uneven, and the bleaching solution penetrates shallowly;

[0004] The second is to put bleaching agents such as hydrogen peroxide and ammonium bicarbonate in the bleaching tank, pressu...

Examples

Embodiment Construction

[0016] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0017] The present invention comprises a nozzle 1, the nozzle is connected to the bottom 21 of the ascending pipe 2, and the top 22 of the ascending pipe is connected to a reaction tank 3 which is higher than the nozzle 1 and has a certain height and enables the nozzle to generate sufficient injection pressure; the position of the reaction tank bottom 31 is higher than that of the nozzle 1. high. The reaction tank is open, and bleaching agent 4 is contained in the reaction tank.

[0018] The position of the bottom 31 of the reaction tank is higher than that of the nozzle 1, so that the gravity of the bleaching solution in the reaction tank and the height difference between the bottom of the reaction tank and the nozzle are used to generate a certain pressure on the bleaching solution sprayed from the nozzle to the surface of the wooden product. ...
