Problems solved by technology

However, the waste paper recycling system in China is just in its infancy, with rough classification and high impurity content. Waste paper sorting is basically manual sorting, lack of sorting standards and training of sorting personnel, the efficiency is extremely low, and the quality of sorted paper is mixed. A lot of high-quality waste paper is not fully utilized, resulting in a second waste

Embodiment Construction

[0019] Below in conjunction with accompanying drawing and embodiment describe in detail:

[0020] In this embodiment, the No. 2 mixed waste paper of the "American Waste Paper Classification Standard" is taken as an example for sorting. This kind of waste paper is mixed with waste paper of different quality after sorting, and is packaged for delivery. The grinding of this kind of waste paper The content of wood pulp shall not exceed 10%, the mixed impurities shall not exceed 0.5%, and the total amount of unqualified waste paper shall not exceed 3%. Including paper items, such as: cardboard, waste newspapers, magazines, office paper, etc.; non-paper items, such as: broken glass, waste plastics, cans, etc.

[0021] Such as figure 1 Shown, a kind of waste paper sorting method, its steps are:

[0022] (1) The first process: This process is a combination of mechanical and manual screening. After manually cutting the packaging belt of the mixed waste paper, the mixed waste paper i...

Abstract

The invention discloses a wastepaper sorting method which comprises the steps that: mixed wastepaper is adequately scattered by a feeder and then transferred by a steel plate conveying belt to a pre-sorter for initial sorting; a large corrugated paper screening machine screens the corrugated paper that is more than or equal to 0.8m in thickness and more than 500g in weight in wastepaper and transfers the screened corrugated paper to a storage take to package, the residual paper is transferred to an old newspaper screening machine to screen wastepaper according to the area of wastepaper and package the wastepaper through a packaging machine, and the residual wastepaper is transferred to a small corrugated paper screening machine to grasp the corrugated paper according to thickness of the residual wastepaper and package the corrugated paper through the storage tank, and the residual wastepaper is transferred to a fine screening machine to sort according to length of the wastepaper; the fine screening machine scans the residual wastepaper by laser and sorts and packages colored magazines and uncolored wastepaper. With adoption of the wastepaper sorting method, the wastepaper resource can be reasonably utilized so as to improve the wastepaper sorting capacity and realize refined sorting.

Description

technical field [0001] The invention relates to a sorting method, in particular to a waste paper sorting method, and belongs to the technical field of waste paper regeneration resource sorting. Background technique [0002] The environment in today's world is deteriorating day by day, and people's awareness of environmental protection is constantly increasing. In order to protect the environment, reduce the load of municipal solid waste (waste paper accounts for about 1 / 3), reduce the felling of forest logs, and maintain ecological balance, the recycling of waste paper (also known as secondary fiber) has increasingly attracted people's attention. According to the "Paper Industry 2010 Annual Report", the total pulp consumption of China's paper industry in 2010 was 84.61 million tons, of which waste paper pulp was 53.05 million tons, accounting for 63% of the total pulp volume. The "Tenth Five-Year Plan" of China's paper industry proposes that the proportion of waste paper ut...
