Embodiment Construction

[0021] Such as figure 1 shown, and refer to figure 2 The laboratory ultrasonic waste paper deinking equipment of the embodiment of the present invention includes: a mixing tank 2 that can be rotated horizontally (rotating relative to a horizontal plane), and a reactor that can move up and down relative to the mixing tank 2; the reactor can pass through the relative Insert or remove mixing bowl 2 with movement.

[0022] The top of the mixing bucket 2 is provided with a circular opening; obviously, the mixing bucket 2 has a cylindrical structure and is a container for holding waste paper solution.

[0023] The reactor comprises: a regular polygonal structure 1 for inserting into the mixing tank 2, and a cylinder 4 for sealing the opening; the regular polygonal structure 1 is fixed on the lower end of the cylinder 4, so The regular polygonal structure 1 is a closed cavity; the inner wall of the regular polygonal structure 1 is provided with a plurality of ultrasonic transducer...

Abstract

The invention relates to the technical field of experimental equipment manufacturing and provides laboratory ultrasonic waster paper deinking equipment. The equipment comprises a stirring drum and a reactor, the stirring drum is capable of rotating horizontally, the top of the stirring drum is provided with an opening, the reactor comprises a regular polygonal structure and a cylinder, the regularpolygonal structure is used for being inserted into the stirring drum, and the cylinder is used for sealing the opening. The regular polygonal structure is an airtight cavity, and a plurality of ultrasonic transducers are arranged on the inner wall of the airtight cavity. The inner side wall of the stirring drum is provided with a plurality of crushing teeth, and the bottom of the stirring drum is provided with a plurality of defibering teeth. By arrangement of the ultrasonic transducers in the reactor, great ultrasonic action nearby the inner wall of the stirring drum can be achieved throughthe hollow structure of the reactor; under the dual actions of stirring and ultrasonic, waste paper is deinked through compression water flow and ultrasonic cavitation, and great deinking performances and high treatment speed are realized.

Description

technical field [0001] The invention relates to the technical field of experimental equipment manufacturing, in particular to a laboratory ultrasonic 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, coll...
