Description

Technical Field

[0002] In industrial production, conical silos are generally used as buffer silos and feeding devices to ensure the continuity of industrial production. In practical applications, traditional conical silo feeding devices have the following defects when in use: high-density and large-particle materials can slide down from the feeding port by their own gravity, but powder materials with lower density and specific gravity are easy to harden and adhere to the silo wall and are not easy to slide down. In particular, powder materials with higher water content are easy to harden and block the feeding port when feeding, which seriously hinders the continuity of feeding and requires operators to perform plugging operations for a long time, reducing the operating efficiency. At the same time, 1. The existing conical feeding device only directly hangs the barrel at the discharge port of the device, lacks stability and is easy to tilt; 2. The sealing effect of the direct connection between the existing conical feeding device and the barrel is poor, which easily causes the material to enter the conical feeding device and damage the device; 3. After the existing barrel is installed on the conical feeding device, it is easy to shake, which easily causes the equipment to tilt or the material to spill; because the existing barrel installed on the conical feeding device cannot accurately control its feeding degree.
