Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal devices, in particular to a cellulose centrifugal device. Background Art

[0002] Cellulose is a commonly used raw material, usually used to produce various food raw materials, fiber products or paper products. The preparation and extraction process of cellulose is usually divided into acidic preparation and alkaline preparation. After the preparation is completed, centrifugal filtration is required to separate the solid cellulose material.

[0003] Existing cellulose centrifugal technology usually relies on the rotation of the centrifuge, and the cellulose particles are attached to the inner wall of the centrifuge. Since the old centrifuge does not have the scraper scraping function, the traditional method is to manually dig out the cellulose on the inner wall of the inner cylinder, which is time-consuming and labor-intensive and has low work efficiency. Purchasing a new centrifuge requires additional equipment costs, which is a considerable expense for the company. In order to save costs, this application is improved on the basis of the old centrifuge, and a material removal component is added to meet the demand for improving work efficiency, thereby saving production costs for the company.
