Problems solved by technology

The recycling of used packaging barrels meets the requirements of the national circular economy, but most of the packaging barrels continue to be used after cleaning. However, due to the lack of professional knowledge and pollution prevention measures and facilities, the waste water from the cleaning is discharged randomly, and even residual substances in the barrels appear. Random dumping will seriously pollute the environment and threaten the safety of the ecological environment

Embodiment 1

[0022] 200L iron bucket crushing ball

[0023] (1) Residual liquid cleaning: remove the lid of the 200L iron drum, and use a vacuum dryer to remove the liquid contained in the drum;

[0024] (2) Twin-shaft shredder shredding: Send the 200L iron barrel to the twin-shaft shredder through the conveyor belt for shredding, and get 60mm wide * 200-320mm long iron pieces, and open the suction facility at the same time to clean the exhaust gas. Collect and turn on the water spray facilities to prevent fire from tearing and friction;

[0025] (3) Washing machine lye cleaning: Put the iron sheet into the washing machine through the conveyor belt for cleaning. The cleaning liquid uses 5% lye, and through soaking and rolling friction, most of the residual liquid and residue on the iron sheet will be removed. After removal, the exhaust gas is collected through the suction hood;

[0026] (4) Grinding machine balls: first turn on the water spray device on the ball grinding machine, put the...

Embodiment 2

[0034] 18L iron bucket crushing ball

[0035] (1) Residual liquid cleaning: remove the lid of the 18L iron drum, and use a vacuum dryer to remove the liquid contained in the drum;

[0036] (2) Twin-shaft shredder shredding: Send the 200L iron drum to the twin-shaft shredder through the conveyor belt for shredding, and get 60mm wide * 100-320mm long iron pieces, and open the suction facility at the same time to clean the exhaust gas. Collect and turn on the water spray facilities to prevent fire from tearing and friction;

[0037] (3) Washing machine lye cleaning: Put the iron sheet into the washing machine through the conveyor belt for cleaning. The cleaning liquid uses 10% lye, and through soaking and rolling friction, most of the residual liquid and residue on the iron sheet will be removed. After removal, the exhaust gas is collected through the suction hood;

[0038] (4) Grinding machine balls: first turn on the water spray device on the ball grinding machine, put the ir...

Abstract

The invention discloses a waste packaging iron drum disposal and recovery method. The method comprises the following steps of (1) cleaning residual liquid in a waste packaging iron drum; (2) shreddingthe waste packaging iron drum through a double-shaft shredding machine; (3) conducting alkali liquid cleaning through a cleaning machine; (4) conducting ball grinding through a ball grinding machine;(5) conducting screening through a magnetic separator; (6) conducting cleaning through a cleaning machine; (7) conducting drying through a drying machine. Through the method, the waste packaging irondrum is subjected to shredding, cleaning, ball grinding, magnetic separation and recleaning, and a large quantity of iron balls are recovered. Meanwhile, produced cleaning wastewater, waste gas and waste residues are reasonably disposed, and resource cyclic regeneration is achieved.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of solid waste, in particular to a treatment of waste packaging iron drums [0002] Set recovery method. Background technique [0003] The chemical industry is one of the pillar industries of my country's economy. Chemical raw materials and products are indispensable and important materials, involving various fields. The use of chemicals is growing steadily, and the subsequent chemical packaging industry is also developing rapidly. Our country uses a large number of chemical packaging barrels every year, and most of them are also cleaned and reused. Chemical packaging barrels generally refer to various packaging containers for storing solid, liquid and semi-liquid viscous chemicals, involving organic and inorganic chemicals, of which there are many types and large quantities. The recycling of used packaging barrels meets the requirements of the national circular economy, but mo...
