[0002] With the progress and development of social science and technology, most of today's buildings have abandoned traditional red bricks and used concrete processing. Concrete is a commonly used building material, mainly made of a mixture of cement, yellow sand and water. Buildings made of concrete have good strength and hardness, and are more heat-resistant and sound-insulating than traditional red brick walls. However, during the mixing production of concrete, the mixing produces a lot of dust, and long-term inhalation can lead to pneumoconiosis and other diseases that affect the health of workers.

[0003] Chinese patent number CN218928191U proposes a dust removal device for building concrete mixing. Although a water adding pipe is arranged inside a sealed mixing tank so that there is no flying dust during the water adding process of mixing concrete, the feed port for adding concrete powder is in an open state during the actual mixing process, so there will still be flying dust. Now there is an urgent need for a dust removal device for building concrete mixing to solve the above problems. Utility Model Content
