Abstract

The invention belongs to the technical field of papermaking, and particularly relates to a papermaking waste plastic cleaning and desizing process and papermaking waste plastic cleaning and desizing equipment. The equipment comprises a cleaning water tank, wherein one end of the cleaning water tank is communicated with a sorting system, the other end of the cleaning water tank is communicated witha friction machine, the friction machine is provided with a solid discharge port used for discharging solid products and a liquid discharge port used for discharging liquid products, the solid discharge port is communicated with a plastic product storage tank, and the liquid discharge port is communicated with a paper pulp product storage tank through a concentration assembly. According to the invention, materials sorted by the sorting system are conveyed into the cleaning water tank to obtain a solid-liquid mixture, the solid-liquid mixture is divided into a solid substance and a liquid substance by using the friction machine, the plastic product storage tank, the concentration assembly and the paper pulp product storage tank, and are respectively stored for later use, the solid substance is used for manufacturing a plastic product, and the liquid substance is used for manufacturing a paper product, so that the quality and the recovery rate of the manufactured paper product are guaranteed, the plastic particles can be recycled, and the resource utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a papermaking waste plastic cleaning and desizing process and equipment thereof. Background technique [0002] At present, the composition of the waste materials used in the papermaking industry is relatively complex. For example, some papermaking enterprises use high-strength American waste. In addition to waste paper and waste plastics, there are more metal sheets, large pieces of metal, wood, and rags in the waste materials. and other impurities. In the prior art, the disposal of waste raw materials is mainly through direct rinsing in the cleaning tank, breaking up the waste plastics in the rinsing tank by means of a paddle or water needle, and separating the components with different specific gravity in water to clean the washing liquid. After filtration, it is concentrated to obtain the pulp stock solution for preparing paper products. However, this producti...
