Description

Technical Field

[0001] The utility model relates to the technical field of latex production, in particular to a latex waste liquid recovery device. Background Art

[0002] Latex waste liquid is the waste liquid generated in the process of producing latex products. Since latex waste contains a large amount of non-volatile substances, it has a certain recycling and reuse value. The recycling of latex waste liquid is generally to recycle the generated waste liquid into a waste liquid storage tank, and add a demulsifier to demulsify and decolorize the wastewater, thereby forming a precipitated colloid.

[0003] The existing latex waste liquid recovery device adds demulsifiers during the demulsification and decolorization process of the waste liquid, but it is generally difficult to quickly mix different liquid layer depths by stirring, and the stirring efficiency is average, resulting in low waste liquid treatment efficiency. In addition, the colloid generated during the demulsification and stirring process of the waste liquid is easy to adhere to the inner wall of the liquid storage tank. If it is not cleaned in time, the colloid accumulation will affect the subsequent waste liquid treatment. Utility Model Content
