Special wastewater recycling and filtering support for easily degradable cellulose packaging film preparation

Abstract

The invention relates to a special wastewater recycling and filtering support for easily degradable cellulose packaging film preparation. Three groups of fixed bulge loops are arranged on a support body; a first filter screen, a second filter screen and a third filter screen are arranged on the fixed bulge loops; a filter leakage tank is arranged on the bottom part of the first filter screen; a conical surface is arranged in the center of the second filter screen; an arc-shaped surface is arranged in the center of the third filter screen, and the arc-shaped surface is of a hemispheroid structure; filter holes are formed in the first filter screen, the second filter screen and the third filter screen. Multiple filter structures are arranged on the support, so that impurities and particulatematters in wastewater can be effectively screened and removed, and an effect on green production is achieved.

Description

technical field [0001] The invention relates to a waste water treatment tool, in particular to a special waste water recycling filter support for preparing easily degradable cellulose packaging film. Background technique [0002] Synthetic films are generally plastic polymers. The production process and product waste will cause huge damage to the natural ecological environment, and the raw materials used to produce such films are petroleum products, which are non-renewable resources. Natural plant cellulose is rich in resources and is an environmentally friendly material. Natural plant cellulose and its derivatives have a long history as raw materials for film production and play an important role in the film production industry. Especially in recent years, various high-performance and functional plant cellulose films have emerged one after another, which is a hot spot in the research of packaging films. [0003] Compared with artificially synthesized polymer films, natural...

Problems solved by technology

[0004] However, in the process of producing cellulose packaging film, due to the need to stir and mix natural cellulose crushing and other reactants, the waste water generated in the production process will be mixed with dust particles and various impurities, which need to be further processed. Treatment can be discharged, otherwise it will pollute the environment
