Embodiment

[0016] A method for recycling waste plastic barrels, which comprises pouring residual liquid, crushing with water, cleaning, frictional separation, dehydration and drying of the plastic barrels in sequence;

[0017] S1 Pour residual liquid

[0018] After the waste plastic barrel enters the production workshop, it first enters the waste dumping area, and uses an automatic liquid suction device to remove excess liquid in the barrel. After pouring out the residual liquid, put the plastic bucket into the vacuum liquid removal tank to remove the liquid for 3 to 5 minutes. The vacuum degree of the vacuum chamber is -60kPa~-90kPa, and then break the air instantaneously to remove the residual liquid in the plastic bucket. The highly concentrated waste liquid in the plastic barrel can be removed centrally by introducing vacuum liquid removal and air breaking, so as to avoid introducing too much residual liquid in the subsequent process.

Abstract

The invention discloses a recycling method of waste plastic barrels. The method comprises the steps of pouring residual liquid of the plastic barrels, crushing at low temperature, cleaning, friction separation, dehydration and drying. According to the resource recycling method of the waste plastic barrels, the waste liquid with high concentration in the plastic barrels can be removed in a centralized way by introducing vacuum liquid removal and air breaking according to the characteristics of dangerous waste plastic packaging barrels, so that the introduction of excessive residual liquid in the subsequent process is avoided. The plastic barrels become brittle at a low temperature, the crushing difficulty is greatly reduced, the crushing time is shortened, and the crushing efficiency is improved, so that the defects of large water consumption and large time consumption of the water-carrying crushing process in the prior art are overcome, the waste liquid in the waste plastic barrels isrecycled, and the consumption of the waste water is reduced by about 60 percent compared with the process in the prior art.

Description

technical field [0001] The invention relates to a recovery process of 5-120L waste packaging barrels. Background technique [0002] Special dangerous goods packaging barrels need to be recycled and disposed of in accordance with the relevant policies of hazardous waste management before they can be reused to prevent secondary pollution and reduce material costs, which is of considerable economic and environmental significance. Establishing a reasonable, energy-saving and pollution-proof recycling production line will generate huge economic and environmental benefits. The application number is 2017108682604, which discloses a refurbishment and treatment method for waste packaging barrels. It provides a relatively complete refurbishment line for waste packaging barrels, but more wastewater is generated during the process. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defect that the special dangerous goods ...
