Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a sludge silo arch breaking device. Background Art

[0002] The operation mode of wet sludge silo is to rely on the gravity of the sludge itself to make it automatically flow to the outlet of the silo. However, the sludge itself has the characteristics of high viscosity, poor fluidity and strong adhesion. The wet sludge in the silo is easy to form arches. During use, the material cannot be discharged due to arches. Once the above situation occurs, it will affect the continuity of the entire production process. The existing announcement number is CN 219383583 U. A sludge arch breaking device drives the synchronous belt through the motor in the adjustment mechanism, thereby driving the second synchronous wheel to rotate, so that the connecting frame drives the reciprocating rod to move back and forth quickly, and then drives the scraper rod to further break the arch of the sludge, so that the sludge falls quickly. However, when the above device is in use, the scraper rod only moves back and forth at the same horizontal height, so that the sludge at other heights of the discharge port still has the defect of adhesion, which may still cause the problem of difficulty in unloading.
