Wastewater filter of nitrocotton

Abstract

The invention relates to the technical field of filters and specifically discloses a wastewater filter of nitrocotton. The wastewater filter comprises a rack, and a transmission device and a filtering system which are arranged on the rack, wherein the filtering system comprises a barrel body and a cylindrical filter screen; the barrel body is transversely arranged on the rack; the cylindrical filter screen is transversely arranged in the barrel body; the transmission device is used for driving the cylindrical filter screen to rotate; shaft necks are arranged at two ends of the cylindrical filter screen and penetrate through the barrel body; the shaft neck at one end is provided with a wastewater water inlet and the shaft neck at the other end is provided with an impurity discharging opening; an impurity collector is arranged below the impurity discharging opening; a pure-water water inlet is formed above the barrel body and a pure-water water outlet is formed below the barrel body; a pure water collector is arranged below the pure-water water outlet. The filter disclosed by the invention is simple in structure, compact and reasonable in arrangement, convenient to repair and maintain, low in manufacturing and utilization cost and high in filtering efficiency; cotton flock can be effectively separated from wastewater and obtained pure water is properly subjected to impurity collection, so that the effects of saving energy and reducing emission are realized.

Description

technical field [0001] The invention belongs to the technical field of filters, and in particular relates to a waste water filter for nitrocellulose, which is used for secondary filtration of waste water after washing nitrocellulose. Background technique [0002] Cellulose nitrate, commonly known as nitrocellulose or nitrocellulose, is the product of the reaction between cellulose and nitric acid. It was originally used in the military field and is an important raw material for the manufacture of propellants, missiles, and rocket propellants. At the same time, nitrocellulose has good film-forming properties. , can be used for the surface layer of metal, wood and other materials, so it is widely used in civil industry, mainly used in the manufacture of various paints, typing stencils, inks, varnishes, bottle seals, adhesives, leather oil, nail polish, Ester-soluble or water-soluble coatings, table tennis balls, piano keys and other products. [0003] At present, domestic nit...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic nitrocellulose production uses refined cotton as raw material. During the production process, a large amount of waste water will be generated, which contains nitrocellulose shavings, making it difficult to recycle waste water. Direct treatment and discharge will lead to waste of nitrocellulose shavings resources.
