Description

Technical Field

[0001] This utility model belongs to the field of bulk loading machine technology, specifically relating to a bulk loading machine for unloading dry ash from an ash silo. Background Technology

[0002] In industrial production processes, particularly in industries such as power, cement, and metallurgy, dry ash (such as fly ash and slag powder) is an important by-product or raw material, and the efficiency and environmental friendliness of its storage, transportation, and use are crucial. As the primary facility for storing this dry ash, the efficient management and environmental control of the unloading process in ash silos directly impact production efficiency and environmental protection.

[0003] Traditional bulk loading machines typically rely on cloth bags for material feeding. While this method can prevent dust leakage to some extent and protect the environment and the health of operators, it has significant drawbacks. Due to the poor flowability of the material itself, coupled with the obstruction and accumulation of the cloth bags, the unloading speed is often extremely slow. This problem seriously affects the overall efficiency, increases production time and costs, and the fixed length of the cloth bags also has certain limitations when discharging materials.

[0004] Therefore, in order to solve the above problems, it is necessary to design a bulk loader for unloading dry ash from ash silos. Utility Model Content
