Description

Technical Field

[0001] The utility model belongs to the field of material storage, and in particular relates to a device for preventing a powdered material storage tank from being blocked. Background Art

[0002] In the production process of hot-rolled seamless steel pipes, after the perforation process, in order to ensure the stability of the inner surface quality of the rough pipe, it is necessary to blow in the antioxidant borax, and the storage box needs to be added with borax in advance for standby use. Due to the inherent adhesiveness of borax and the humid environment of the production site, the storage box is used for storage, which has the characteristics of small footprint and high effective volume. However, in the process of storing borax, due to its water content and stone powder content, it is easy to arch, resulting in poor discharge or hardening and unable to discharge, seriously affecting normal production. Due to the accumulation on the inner surface of the storage tank, the discharge port is blocked, and the borax in the tank cannot flow downward normally to feed, causing the entire line to stop production and affecting production efficiency. At the same time, the operator will use a sledgehammer to knock on the outer wall of the silo and use vibration to make the material go down, which increases the labor intensity of the operator.

[0003] In view of the above factors, a device is specially designed to prevent the powder storage material discharge tank from being blocked, so as to solve the problem that the mixed material in the silo is semi-wet, the friction between the material and the inner surface of the silo is large, the material is easy to accumulate in the silo, and the discharge is difficult.
