[0002] Concrete silos refer to warehouses used to store concrete raw materials, such as cement, sand, aggregates, etc. The main function of concrete silos is to ensure the supply of raw materials for concrete production in mixing plants, and to adjust the supply of concrete raw materials to ensure the quality of concrete produced.

[0003] China's authorization announcement number CN205380781U discloses a new type of powder storage silo for a concrete mixing station, which includes a silo, a silo cover, a dust collector, a wear-resistant elbow connected to the silo discharge port, a dust shield provided on the upper part of the silo, and a support leg provided at the bottom of the silo. A weighing sensor is installed on the support leg, and the weighing sensor is connected to a weight display device through a wire. The dust shield is a conical thin-walled structure, and a convection hole is provided below the dust shield. The silo cover and the dust shield form a conical cavity, and the dust collector is connected to the conical cavity through a conduit. The wear-resistant elbow includes an elbow and a shell provided outside the elbow, and the shell is filled with concrete. The inner surface of the elbow is evenly distributed with multiple raised flow blocking rings. The utility model is equipped with a weighing sensor, and the cement in and out data can be grasped at any time. The storage and consumption of materials can be effectively controlled, and the silo explosion phenomenon is eliminated. The dust removal efficiency is high, and the replacement frequency of the wear-resistant elbow is reduced.

[0004] However, the device has the following defects when in use: when the device is discharging concrete powder and loading it into a truck, due to the certain height between the wear-resistant elbow and the bottom wall of the truck compartment, a high drop will be generated during discharging, causing the powder to splash large dust and affect the environment. In view of the above defects, we propose a dust removal device for concrete powder silo. Utility Model Content
