Description

Technical Field

[0001] This utility model relates to the technical field of antioxidant production equipment, and in particular to a multi-stage screening device for finished antioxidant products. Background Technology

[0002] Antioxidants are essentially weak reducing agents. Depending on the industrial application, a corresponding weak reducing agent can be selected as the antioxidant component. Generally, weak reducing agents with high chemical and physical stability or low toxicity can be cleverly used in the formulation of corresponding antioxidants.

[0003] Screening is a crucial step in the production of some antioxidants, using sieves to classify antioxidants of different diameters. However, existing antioxidant sieving devices typically have a fixed number of sieves. When additional sieves are needed to achieve more stages of screening during production, this method is inadequate. Furthermore, dust generated during screening cannot be promptly collected, leading to a dusty working environment. Therefore, this invention proposes a multi-stage antioxidant sieving device to address the shortcomings of existing technologies. Utility Model Content

[0022] Each of the multiple sets of screening discs 4 has a discharge chute 16 located below the outer wall, and a valve plate 17 is movably installed on the top of each discharge chute 16. The discharge chute 16 is used to discharge the screened antioxidant product.

[0023] This invention features a dust collection seat 3 mounted on the mounting base 2 at the output end of the vibrating base 1. Multiple sets of screening discs 4 with different screening apertures are then stacked and installed on the dust collection seat 3. After the collection pipe 5 is connected to an external negative pressure collection device, the dust generated during the screening process can be effectively collected, preventing dust from flying. The multiple sets of screening discs 4 are movably assembled with the positioning rod 6, allowing for the addition of screening discs 4 at any time to screen higher-grade antioxidant products. The device is highly flexible in use. The multiple sets of stacked screening discs 4 are pressed together by the cover plate at the output end of the lifting cylinder 9, which has the advantage of simple operation.
