Problems solved by technology

In this traditional papermaking method, a large amount of water and dyes must be used in pulping, which will firstly cause a great waste of dyestuff costs, and secondly, a large amount of dyed pulping water must be decolorized before it can be discharged to the outside.
Cloth dyeing is similar. These traditional equipment greatly increase the difficulty and cost of papermaking and cloth dyeing wastewater

Embodiment 1

[0023] In this embodiment, an intelligent horizontal spray-dyeing equipment and its auxiliary system are used to uniformly color the paper in the papermaking production line to produce brightly colored colored paper. The present invention is achieved in the following way: an intelligent horizontal spray dyeing equipment unit, comprising upper and lower spray dyeing boxes (1, 2); upper and lower negative pressure gas-liquid recovery boxes (3, 4); dye supply pipelines (5); Dye recovery pipeline (6); Dye material tank (7); Compressed air supply pipeline (8); Nozzle (9); Air storage tank (10); Air compressor (11); Negative pressure vacuum pump (12 ); gas-liquid separator (13); gas distribution device (14); liquid distribution device (15). In order to ensure the stable supply of dye, it is necessary to configure a material tank, which is connected to the liquid distribution device through the dye supply pipeline, and is delivered to each nozzle through the liquid distribution devic...

Embodiment 2

[0032] This embodiment introduces the practical application of applying the device to the printing and dyeing of red paper.

[0033] Add the red dye into the dispensing tank together with water in a certain proportion according to the process requirements. After stirring evenly, put the mixed dye into the storage tank through the booster pump for standby. After the equipment is started, the system detects the pressure of the compressed air in the storage tank and whether the liquid level of the dye tank meets the requirements. If it does not meet the requirements, the PLC will automatically control the start of the air compressor or the feeding of the automatic feeding system. When the spray-dyeing processing conditions are met, the soaked paper will slowly enter the intelligent horizontal spray-dyeing equipment driven by the transmission system. The compressed air control valve automatically opens a certain opening (can be set on the PLC control interface according to the pro...

Embodiment 3

[0035] This example introduces the practical application of applying the device to the printing and dyeing of blue cotton cloth.

[0036] Add the blue dye into the dispensing tank together with water in a certain proportion according to the process requirements. After stirring evenly, put the mixed dye into the storage tank through the booster pump for standby. Whether the pressure and the liquid level of the dye tank meet the requirements, if not, the PLC automatically controls the start of the air compressor or the automatic feeding system to feed. When the spray-dyeing processing conditions are met, the soaked cotton cloth slowly enters the intelligent horizontal spray-dyeing equipment driven by the transmission system. The compressed air control valve automatically opens a certain opening (can be set on the PLC control interface according to the process needs), the nozzle starts to spray air, and at the same time the dye is automatically sucked into the nozzle through the ...

Abstract

The invention discloses an intelligent horizontal spray-dyeing device and a use method thereof. The intelligent horizontal spray-dyeing device is used for uniform paper or cloth coloring and comprisesupper and lower spray-dyeing box bodies (1 and 2), upper and lower negative-pressure air-liquid recovery box bodies (3 and 4), a dye supply pipeline (5), a dye recovery pipeline (6), a dye tank (7),a compressed air supply pipeline (8), a spray nozzle (9), an air storage tank (10), an air compressor (11), a negative-pressure vacuum pump (12), an air-liquid separator (13), an air distributing device (14) and a liquid distributing device (15). By applying the intelligent horizontal spray-dyeing device, dyes can be decreased by 40% when colorful paper or fiber textile products are printed and dyed, the water use amount can be decreased by 30%, the COD, BOD and chrominance of printing and dyeing wastewater are greatly reduced, the sewage treatment cost is reduced by 70%, the reuse times of the printing and dyeing wastewater are increased, and the purposes of saving energy, reducing emissions and saving water resources are achieved.

Description

technical field [0001] The invention relates to the field of dyeing of products in the papermaking industry and the textile industry, in particular to an intelligent horizontal spray dyeing device and a method for using the same. Background technique [0002] The traditional method of dyeing in the paper industry is to add dyes dissolved in water directly into the pulp during the pulping process to color the pulp and then create colored paper. This traditional papermaking method must use a large amount of water and dyes during pulping, which will firstly cause a great waste of dyestuff costs, and secondly, a large amount of dyed pulping water must be decolorized before it can be discharged externally. Cloth dyeing is similar. These traditional equipment greatly increase the difficulty and cost of papermaking and cloth dyeing wastewater. [0003] The paper printing and dyeing and cloth printing and dyeing industries are industries with large industrial water consumption and ...
