Pretreatment hazardous waste storage bin

Abstract

The invention relates to a pretreatment hazardous waste storage bin. The pretreatment hazardous waste storage bin comprises a bin body, a conveying assembly, a crushing assembly, a collecting box and a flow guide pipe, wherein the conveying assembly is arranged above the bin body, the crushing assembly is arranged on the outer side of the conveying assembly, the crushing assembly is arranged on the inner wall of the bin body, the collecting box is arranged below the crushing assembly, the flow guide pipe is connected to the collecting box, and the flow guide pipe penetrates through the bin body. According to the pretreatment hazardous waste storage bin, the problems existing in the recovery treatment of waste battery electrolyte can be solved, wherein the problems are that a, when existing waste battery electrolyte is subjected to recovery treatment, a battery is often crushed in a manual hammering mode, the crushing efficiency is low, and the human health is prone to being harmed; and b, when the existing waste battery electrolyte is poured into the collecting box, the situation that the electrolyte splashes frequently occurs, the splashed electrolyte drops outside a collecting vessel, and the loss of the electrolyte is increased.

Description

technical field [0001] The invention relates to the technical field of waste treatment, in particular to a pretreatment hazardous waste storage bin. Background technique [0002] Hazardous waste refers to substances with one or more hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity, or infectivity. At present, the storage and disposal of hazardous waste materials often pollute the environment for the second or third time. Due to the lack of complete and good hazardous waste storage bins due to environmental conditions, soil or air conditions, the waste liquid and gas discharged during the disposal of hazardous waste will directly enter the external environment and cause pollution; there are many types of hazardous waste at present. Different types of hazardous waste also have different disposal methods and requirements. [0003] For example, waste batteries or waste light bulbs, etc., existing hazardous wastes often require multi-level trea...

AI Technical Summary

Problems solved by technology

[0002] Hazardous waste refers to substances with one or more hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity, or infectivity. At present, the storage and disposal of hazardous waste materials often pollute the environment for the second or third time. Due to the lack of complete and good hazardous waste storage bins due to environmental conditions, soil or air conditions, the waste liquid and gas discharged during the disposal of hazardous waste will directly enter the external environment and cause pollution; there are many types of hazardous waste at present. Different types of hazardous waste also have different disposal methods and requirements

[0003] For example, waste batteries or waste light bulbs, etc., existing hazardous wastes often require multi-level treatment, and in order to protect the environment, they are often treated in a closed storage bin, and waste batteries need to be processed first. The electrolyte is discharged, and the discharged electrolyte can recover copper sulfate and crude nickel through chemical recovery, but there are still certain problems in the existing waste batteries when the electrolyte is discharged

[0004] The following problems often exist when the existing waste battery electrolyte is recycled: a: when the existing waste battery electrolyte is recycled, the battery is often broken by manual hammering, and the crushing efficiency is low. And it is easy to endanger human health; b: when the existing waste battery electrolyte is poured into the collection box, the electrolyte splash often occurs, and the splashed electrolyte drops outside the collection container, which increases the loss of electrolyte
