Ultrasonic waste paper deinking pretreatment device

Abstract

The invention provides an ultrasonic waste paper deinking pretreatment device, and belongs to the field of waste paper regeneration equipment manufacturing. The conveying device comprises a conveying belt and two metal hard plates, the two metal hard plates are arranged in parallel, and the two metal hard plates are respectively provided with corresponding surfaces and back surfaces; a plurality of ultrasonic vibration plates are arranged on each back surface; the conveying belt comprises two rollers which are arranged in parallel and a conveying belt; the conveying belt is annular, and the two rollers are connected through the conveying belt; the two metal hard plates are positioned between the two rollers; a plurality of evenly-distributed rubber scraping plates are arranged on the two side faces of the conveying belt, and the conveying belt makes contact with the two corresponding faces through the rubber scraping plates. A large amount of ultrasonic waves are generated in the two parallel metal hard plates, waste paper is crushed and deinked through ultrasonic vibration compressed water flow and the ultrasonic cavitation effect, ultrasonic energy can be intensively released, and waste paper liquid obtained after pretreatment has the excellent deinking performance.

Description

technical field [0001] The invention relates to the manufacturing technology of waste paper processing equipment, in particular to an ultrasonic waste paper deinking pretreatment device, which belongs to the technical field of waste paper deinking manufacturing. Background technique [0002] The ink adheres the pigment particles in the ink to the paper fibers through printing, and the principle of deinking is exactly the opposite of the printing principle, which is to destroy the adhesion of these particles to the fibers. The deinking process of waste paper is a combination of chemical reaction and physical reaction. Generally, the adhesion of printing ink to fibers is destroyed by deinking chemicals, and the ink is separated from the fibers under the action of appropriate temperature and mechanical external force. The process of coming down and separating it from the pulp. [0003] The traditional method of deinking is chemical method. In the deinking method of chemical w...
