A plastic turnover box cleaning system with zero discharge of sewage and its working method

Abstract

The invention discloses a plastic turnover box washing system with zero drainage of sewage and a working method thereof. The system comprises a soaking module, a washing module and a water cycle treatment module; the water cycle treatment module comprises an adjusting tank, an air flotation device, a fenton oxidation pond, a sloping panel filter pond and a quartz sand filter; and the adjusting tank is sequentially connected with the air flotation device, the fenton oxidation pond, the sloping panel filter pond and the quartz sand filter through water pipes. A comprehensive objectification treatment method is adopted for washing sewage away. Washing sewage is subjected to accurate comprehensive treatment of rough and fine filtering procedures in the adjusting tank, the air flotation device, the fenton oxidation pond, the sloping panel filter pond, the quartz sand filter, a precision filtering tank and the like, and the use standard of washing water is achieved. The treated washing water enters a washing machine again for washing operation. Tap water resources are saved, and the highest effect of zero drainage of the washing sewage is also achieved. By the adoption of a three-dimensional overall framework and the modular design, the floor space is greatly reduced.

Description

technical field [0001] The invention relates to a cleaning device in an industrial production chain, in particular to a plastic turnover box cleaning machine. Background technique [0002] In the field of logistics technology in the modern industrial production chain, using plastic turnover boxes instead of cartons to pack industrial products for transportation is an important measure that is both environmentally friendly and economical. However, plastic turnover boxes need to be cleaned during the turnover process before they can be put into use again. In order to efficiently clean plastic turnover boxes in large quantities, Chinese patent CN201620597348.8 discloses a plastic box cleaning machine, which is equipped with a soaking pool, a cleaning box, a spin dryer and a drying box in sequence; the plastic boxes are installed in In the metal cage, the metal cage is hung on the chain and moves synchronously with the chain. The cleaning machine realizes the cleaning requireme...
