Device for cyclically processing and reutilizing wastes of plastic printing

Abstract

The invention relates to the technical field of environment protection, and specifically relates to a device for cyclically processing and reutilizing wastes of plastic printing. The device comprisesa kettle body, a kettle bottom, a heating device, a stirring device, slag removing cutters, a condenser, and a solvent recovering pot. The kettle bottom is in an inverted conical shape. A discharge pipe is welded to the bottom of the kettle bottom. The periphery of the kettle bottom is provided with the heating device. The stirring device comprises a stirring shaft, which is driven to rotate by adeceleration motor. A stirrer is arranged on the stirring shaft. A first shaft sleeve is welded on the stirring shaft. Cross bars are welded on the first shaft sleeve. The cross bars are divided intoa left group and a right group. The cross bars are provided with oblique rods. The slag removing cutters are arranged on the oblique rods. The device is scientific and reasonable; the kettle body withan inverted conical shape is used to distill aqueous printing ink wastewater, the residues will not be left in the kettle body, moreover, the stirrer has the advantages of high stirring strength, simple structure, and stable and reliable operation; the organic solvent in aqueous printing ink wastewater can be cyclically processed and utilized, the cost is low, and the device is environmentally friendly and low carbon.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a plastic printing waste recycling treatment and reuse device. Background technique [0002] Plastic printing is printing on plastic rolls such as film, sheet, artificial leather, and wallpaper. It is a method of plastic decoration, and its basic principle is the same as that of paper printing. At present, the domestic plastic printing and packaging industry generally adopts water-based ink printing technology. During the use of water-based ink, because of the need to clean printing-related equipment, such as: washing sticks, washing tanks, washing buckets, etc., a certain amount of water-based ink will inevitably be produced. Ink waste water. Water-based ink wastewater contains a large amount of organic solvents. The traditional treatment method is to transfer the water-based ink wastewater to distillation equipment. The gas distilled by the distillation equipm...

Problems solved by technology

Manual slag discharge must rely on tools to slowly wash out the residue, which is laborious to operate and not easy to clean up

Machine dumping and slag discharge is by manually dumping the entire machine for about 120 o , the residue in the barrel flows out by gravity. If the residue in the barrel becomes solid or thick, it usually needs to be cleaned by other auxiliary tools, which is time-consuming and laborious.

[0004] Existing distillation equipment generally uses jacket indirect heating or direct heating through heaters, which consumes a lot of energy. In order to improve distillation efficiency, agitators are often equipped in the prior art. As the distillation process progresses, the viscosity of water-based ink wastewater is getting higher and higher. Larger, the stirring efficiency of the conventional stirrer will become lower, resulting in insufficient distillation and more organic solvents in the residue
