Description

Technical Field

[0002] Silica gel has high adsorption properties and is widely used in drying, moisture-proofing and other fields. In the production and processing of silicone products, the silica gel granular materials used need to be screened to ensure that the particle size of the silica gel particles used is suitable for the processing of silicone products. Therefore, a vibrating screening machine is needed to screen the plastic particles to facilitate the production of silicone products.

[0003] In a Chinese patent with publication number CN215466051U, a multi-stage screening silica gel vibrating screen is disclosed, in which side plates are hingedly provided on both sides of a middle plate, and when the side plates are tilted upward along the hinges with the middle plate, the silica gel particles on the side plates roll quickly onto the middle plate; however, when the multi-stage screening silica gel vibrating screen transfers the plastic on the side plates to the middle plate, it is easy to cause too many plastic particles on the middle plate, causing the plastic particles to accumulate, which is easy to cause a slow screening speed, resulting in low screening efficiency, increased screening time, and further increased processing time. Therefore, we propose a vibration screening machine. Utility Model Content
