Rapid mixing type waste paper recycling and deinking device

Abstract

The invention discloses a rapid mixing type waste paper recycling and deinking device. The device comprises a deinking box, a waste liquid box and a waste paper input box, and the waste liquid box andthe waste paper input box are located on the upper side and the lower side of the deinking box respectively. A partition plate is arranged in the deinking box to divide the interior of the deinking box into two cavities with the tops communicated. A stirring and mixing cavity is formed in the left side of the partition plate, a transfer cavity is formed in the right side of the partition plate, the stirring and mixing cavity is communicated with the waste paper input box, and the transfer cavity is communicated with the waste liquid box. A stirrer is arranged in the stirring and mixing cavity, a pulse motor connected with the stirrer is arranged on the outer wall of the deinking box, and a deinking agent input port is further formed in the top of the deinking box. When the device is usedfor stirring and mixing, a plurality of stirring shafts are used for stirring at different positions, so that the mixing efficiency is greatly improved, the rotational flow phenomenon caused by a conventional single fixed stirring mode is avoided, the sufficient action of a deinking agent on ink particles on waste paper can be ensured, and the deinking efficiency is greatly improved.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to a rapid mixing type waste paper recycling and deinking device. Background technique [0002] Ink is to adhere 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 chemical reaction A process combined with physical reactions, generally through deinking chemicals to destroy the adhesion of printing ink to fibers, and under appropriate temperature and mechanical external force, the ink is separated from the fibers and separated from the pulp crafting process.

Problems solved by technology

[0003] Chinese patent application publication number CN110952360A proposes a waste paper deinking machine, and Chinese patent authorization announcement number CN209482046U proposes a waste paper deinking device, both of which are used for waste paper deinking when waste paper is recycled. The method of mixing waste paper and deinking agent is to mix waste paper and deinking agent. This is also the usual way of deinking large quantities of waste paper. Most of the stirring devices of the equipment have a single stirring method, which is easy to generate swirl during the stirring process, which reduces the effect of physical impact and pull, resulting in low efficiency of ink particle separation and affecting processing efficiency
