Description

TECHNICAL FIELD

[0001] The application relates to the technical field of dry sludge storage, in particular to a dry sludge storage bin. BACKGROUND

[0002] Sludge is a byproduct of sewage treatment, containing a large amount of organic matter and pollutants. If not properly treated, it will seriously pollute the environment and cause resource waste. Dry sludge is prone to hardening and bridging during storage due to its high water content and special physical properties, which seriously affects the normal operation of subsequent processes.

[0003] In practical applications, in order to improve the storage and conveying efficiency of dry sludge, the following methods are usually used: 1. using a single large-capacity bin for storage, which is simple and easy to implement, but is prone to dry sludge caking, affecting discharge; 2. using multi-stage bin for grading storage, reducing caking by layer management, but this design is complex and costly; 3. using a vibrating device to assist discharge, which helps dry sludge flow smoothly through physical vibration, but long-term use increases equipment maintenance costs.

[0004] For the above related technologies, although the above methods solve the problem of dry sludge storage and discharge to some extent, there are still obvious defects. In particular, for large-capacity bins, dry sludge is prone to caking inside the bin, causing poor discharge, even blocking the discharge port, which seriously affects the continuous conveying and processing efficiency of dry sludge.
