Paper pulp molding packaging waste recycling method

Abstract

The invention relates to a paper pulp molding packaging waste recycling method, in which a recovery processing device is utilized, which comprises a shell, a spraying device and a smashing device. A specific process of using the recovery processing device for recycling the paper pulp molding packaging waste comprises the following steps of: material delivery, spray wetting, stirring and chopping,material discharge, and circulating operation. According to the invention, the mashing device and the spraying device cooperate with each other; the action of firstly spraying and then crushing the waste is realized; the waste can be softened before being crushed; the crushing difficulty is reduced, the angle of the spraying pipe can be intermittently adjusted in the spraying process so as to ensure the spraying uniformity, and the pressing mechanism can intermittently extrude the waste in the crushing process, so that the waste can be intensively distributed in the shell, and the time required for crushing can be shortened.

Description

technical field [0001] The invention relates to the technical field of environmental protection machinery, in particular to a method for recycling and treating pulp molding packaging waste. Background technique [0002] Pulp molding is a three-dimensional papermaking technology. Pulp molding is not only used as lunch boxes and tableware, but also used as industrial buffer packaging. It develops very rapidly. It uses waste paper as raw material and is made of special molds on the molding machine. Shaped paper products. When pulp molding packaging materials need to be recycled for secondary use, they need to be sprayed and crushed, and there are some problems in the above treatment process; [0003] (1) The spraying angle of the spray pipe is fixed, and the spraying range is small. Therefore, when the waste packaging materials in the spraying range of the spray pipe are soaked, the waste packaging materials in other positions are still not soaked. , in order to ensure the un...

Problems solved by technology

[0003] (1) The spraying angle of the spray pipe is fixed, and the spraying range is small. Therefore, when the waste packaging materials in the spraying range of the spray pipe are soaked, the waste packaging materials in other positions are still not soaked. , in order to ensure the uniformity of infiltration, it is necessary to wait for a long time, which not only delays the work progress, but also causes a waste of water;

[0004] (2) In the process of crushing waste packaging materials, the blade often only rotates reciprocatingly, and the position of the blade and the rotating shaft is relatively fixed, so it can only crush waste packaging materials within the diameter range of the blade, and it is difficult to distribute them. The waste packaging materials in all parts of the crushing equipment are fully contacted, so the thoroughness of the crushing cannot be guaranteed, and the sizes of the waste packaging materials after crushing are quite different, which increases the difficulty of subsequent processing
