Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment devices, and in particular to a silo device with a bypass arch-breaking structure. Background Technology

[0002] When the moisture content of the dry mud cake is below 50%, it has high viscosity and poor fluidity. During storage in the silo, it is very easy for blockage or arching to occur at the outlet of the silo due to its own weight, stacking method and friction with the inner wall of the silo.

[0003] Common methods for breaking up arches and assisting in material feeding, such as air cannons and vibrators, are ineffective when dealing with dry mud cakes with high moisture content. While the instantaneous impact of air cannons can cause some disturbance to the material, the stickiness of dry mud cakes makes them difficult to disperse effectively, and frequent use of air cannons can easily cause wear on the inner wall of the hopper. Vibrators use mechanical vibration to make the material slide down; however, for dry mud cakes that are highly viscous and tightly compacted, vibration alone is insufficient to break the internal cohesion and structural stability, making it impossible to achieve continuous and smooth material feeding.

[0004] Furthermore, existing silo devices lack optimization for the characteristics of high-moisture-content dry mud cakes in their design. Their simple, single-method arch-breaking and structural design cannot meet the demands for efficient and stable conveying of dry mud cakes in actual production. Therefore, developing a silo device specifically designed for high-moisture-content dry mud cakes, with integrated arch-breaking and feeding functions, is of significant practical importance. Utility Model Content
