Description

Technical Field

[0001] The utility model relates to the technical field of silica gel particle classification, in particular to a rotary vibrating screen for silica gel particle classification. Background Art

[0002] The main component of inorganic silica gel is silicon dioxide, which is an amorphous machine-made product made of sodium silicate and sulfuric acid in silica. As a desiccant, the average pore size of silica gel is 24 angstroms (unit of length). It can still absorb moisture even when the temperature is greater than 105°C, but when the temperature is greater than 38°C, its moisture absorption rate begins to decrease. Its optimal moisture absorption state is 21°C--32°C. Even when the relative humidity is as high as 60%--90%, the relative humidity in the container can be maintained at 40%. During the production process of silica gel particles, a particle screening device is required to screen particles of different diameters.

[0003] In the process of classifying silica gel particles, a rotary vibrating screen is usually used for screening. The existing rotary vibrating screen for silica gel particles is generally composed of a screen frame, a motor, a spring, a base and other components. Its structure is relatively simple. In the process of screening silica gel particles, the screen is prone to clogging, which reduces the screening efficiency. In addition, the screen base has no reinforcement structure. After long-term use, the middle part of the screen is prone to dent and break, which reduces the service life of the screen. Therefore, it is necessary to propose a rotary vibrating screen for classifying silica gel particles to solve the above-mentioned problems. Summary of the invention
