Embodiment Construction

[0023] Such as figure 1 shown, and refer to figure 2 The industrial waste paper deinking equipment of the embodiment of the present invention includes: a reactor 1, and a stirring drum 2 set outside the reactor 1. The vertical cross-section of the mixing tank 2 is circular, and the vertical cross-section of the reactor 1 is polygonal, and the positions of the central points of the two cross-sections are the same.

[0024] The reactor 1 is a tubular structure arranged horizontally, and the vertical section of the reactor 1 is a regular polygonal structure; the regular polygonal structure can make the waste paper solution locally and continuously compressed and decompressed during the stirring process of the mixing tank , very helpful to improve the stirring performance of the waste paper solution.

[0025] Generally, the regular polygonal structure is regular pentagon, regular hexagon, regular heptagon or regular octagon; preferably regular hexagon and regular heptagon; opti...

Abstract

The invention provides an industrial deinking device for waste paper, and relates to the technical field of waste-paper processing device manufacturing. The device comprises a reactor and a stirring barrel; the reactor has a horizontally-arranged tubular structure, and the vertical cross section of the reactor has a regular polygonal structure; the reactor comprises a plurality of ultrasonic wavevibration plates installed on the inner wall of the reactor, and a fan arranged in the reactor; two ends of the tubular structure are respectively provided with a gas inlet and a gas discharge outlet;the stirring barrel rotates relative to the reactor; a closed cavity is formed between the stirring barrel and the reactor; and a plurality of stirring teeth are arranged on the inner side wall of the stirring barrel. According to the device provided by the invention, the ultrasonic wave vibration plates are arranged in the reactor, and a hollow structure of the reactor is utilized, so that ultrasonic waves well act near the inner wall of the stirring barrel; through double action of stirring and the ultrasonic waves, a compressed water flow and ultrasonic cavitation are utilized for deinkingof the waste paper; and the device has excellent deinking performance and a high-efficiency processing speed.

Description

technical field [0001] The invention relates to the technical field of production equipment manufacturing, in particular to an industrial waste paper deinking equipment. Background technique [0002] Ink adheres the pigment particles in the ink to the paper fibers through printing, and the principle of deinking is just the opposite of the principle of printing, which is to destroy the adhesion of these particles to the fibers. The deinking process of waste paper is a process that combines chemical and physical reactions. Generally, deinking chemicals are used to destroy the adhesion of printing ink to fibers, and the ink is separated from the fibers under appropriate temperature and external mechanical force. The process of coming down and separating it from the pulp. [0003] The traditional method of deinking is chemical method. In the chemical waste paper deinking method, sodium hydroxide, sodium silicate, chelating agent, hydrogen peroxide, dispersant, collector and ag...
