Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a material screening device for construction engineering. Background Art

[0002] The economic development model of recycling building renewable resources and continuously recycling materials is becoming a global trend. Sustainable development is the development that meets the needs of contemporary human beings without damaging the ability of future generations to meet their needs. The main sign is that resources can be used forever and maintain a good ecological environment.

[0003] In building materials, existing large-particle plastic renewable resources are usually crushed by crushing equipment and then recycled. However, since there may be some metal or solid particle impurities in the plastic, it is inconvenient to clean after crushing. Therefore, it is necessary to use a screening device to screen and filter before crushing. Most of the existing screening devices screen by vibrating the screen to filter out the particle impurities or metals.

[0004] However, the existing screening devices still have certain deficiencies when used. For example, some sand and soil may adhere to the surface of the plastic, and it is difficult to separate the sand and soil from the plastic during screening, resulting in impurities still existing on the surface of the plastic after screening. Summary of the invention
