Description

Technical Field

[0001] The utility model belongs to the technical field of concrete raw material screening, in particular to a screening device for concrete raw materials. Background Art

[0002] Concrete is abbreviated as concrete, which is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement concrete obtained by mixing cement as a cementitious material, sand and stone as aggregates, and water in a certain proportion. It is also called ordinary concrete. It is widely used in civil engineering. Publication No.: CN215964774U discloses a screening device for concrete raw materials, which involves the field of concrete processing equipment and aims to solve the problem that the existing technology has a single vibration direction and cannot perform multi-stage screening. The technical solution adopted Yes, by installing a second abutment plate above the filter box, the longitudinal vibration of the filter box can be achieved, and the filter box can vibrate in multiple dimensions, so that the screening effect of the screen plate is better and less prone to clogging; the screen plate is divided into multiple split areas, and each screening area is separated by a partition and a discharge port is set under each screening area. Materials of different particle sizes are discharged from different discharge ports, which is convenient for multi-stage screening of the screen plate. A coarse material discharge port is set at the end of the screen plate, which can discharge materials that cannot pass through the screen plate and avoid accumulation on the screen plate or in the separation box, thereby ensuring the sustainability of the screening operation and facilitating the cleaning of coarse materials.

[0003] However, there are some problems with the prior art: when screening concrete raw materials, the most common method is vibration, which uses vibration to make the raw materials in the device jump, thereby achieving screening. However, the existing device is more troublesome during vibration screening and cannot save labor very well. Moreover, the filter box will be damaged or need to be cleaned after long-term use, and the filter box needs to be disassembled and maintained in time. Therefore, the traditional device can no longer meet people's daily work needs. Therefore, we propose a screening device for concrete raw materials. Utility Model Content
