Description

Technical Field

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

[0002] A sludge silo is a device used to store and process sludge. It is usually a closed container used to store sludge generated from the water treatment process. The use of a sludge silo can effectively reduce the impact of sludge on the natural environment. However, the capacity of the sludge silo is limited, and transportation equipment is required to regularly transport the sludge stored inside. Therefore, the stable operation of the unloading device is essential.

[0003] For this purpose, the utility model patent with announcement number CN202728986U discloses a sludge silo unloading device, which is located at the lower part of the sludge silo and includes a plurality of spiral feeders; the central axes of the plurality of spiral feeders are arranged in multiple directions in a horizontal plane and are opposite to each other in pairs. The utility model has the advantages of simple structure and high efficiency, and can be widely used for feeding viscous materials such as sludge. The utility model aims to solve the problem of uniform unloading of sludge containing blocky substances in the sludge silo with high viscosity. By using two opposite reverse spirals, the material is pushed to the discharge port at the same time. The diameter of the feed port is larger than the diameter of the discharge port, and the feed speed is lower than the discharge speed, so as to achieve the effect of breaking the arch. When the feed port is blocked, a strong and fast airflow is used to break the obstruction of the block to ensure continuous feeding and uniform unloading.

[0004] However, this patent uses an air jet to break up large pieces of sludge, and the air outlet of the air jet may be blocked by other sludge, thereby weakening the power of the air jet. In addition, the sludge is relatively confined, and the gas ejected by the air jet is difficult to handle. In addition, this patent cannot promptly detect when the discharge port is blocked.
