Description

Technical Field

[0001] The utility model relates to the technical field of degassing devices, in particular to a degassing device for producing nitrile latex. Background Art

[0002] Nitrile latex is made by copolymerization of butadiene and acrylonitrile emulsion. Since the copolymer molecular chain contains nitrile groups, it has good oil resistance, solvent resistance and chemical resistance, good adhesion with polar substances such as fiber and leather, and good compatibility with polar polymers such as starch, casein, vinyl resin, phenolic resin, urea-formaldehyde resin, etc. In the process of producing nitrile latex, a degassing device is required. When used, the gas discharged from the degassing is directly discharged into the air. The gas contains harmful substances and is easy to cause air pollution. In addition, the free gas and dissolved gas in the nitrile latex raw material at the lower end are not easy to release and degas.

[0003] Most of the existing degassing devices achieve the purpose of degassing by driving the stirring blades of the motor to stir the raw materials in the tank body. However, the stirring of the raw materials is often not thorough enough during use, and the raw materials are easily solidified and adhered to the tank wall during the stirring process, resulting in poor degassing effect of the raw materials or being discarded after failing to meet the use requirements, thereby causing a waste of resources. Secondly, the gas generated during the degassing process is difficult to filter due to the cumbersome installation steps of the filtering device, the inconvenient subsequent inspection and maintenance, the lack of stability and flexibility, and is not conducive to long-term use and promotion.
