After dehydration, the moisture content of the sludge can be reduced to 55% to 80%, depending on the properties of the sludge and sediment and the efficiency of the dehydration equipment. Further dehydration of the sludge is called sludge drying. The moisture content of dried sludge is less than 10%. The main dehydration methods are natural drying, mechanical dehydration and granulation. Natural drying and mechanical dehydration are suitable for sewage sludge. Granulation is suitable for coagulated and precipitated sludge.

The utility model drives two cleaning rods up and down by the hydraulic cylinder, and can clean the mud cake adhered to the mud outlet into the blanking plate, avoiding the mud cake blocking the mud outlet and ensuring the smoothness of the mud outlet. The vibration of the blanking plate is realized by the mutual cooperation of the vibration motor and the second spring, and the vibration can accelerate the speed of mud cake unloading and improve work efficiency.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that when unloading, too much sludge will be blocked in the discharge port, and the sludge blocked in the discharge port cannot be quickly unloaded, which reduces the sludge dewatering and unloading efficiency. In addition, when in use, after the sludge is dehydrated, the moisture on its surface cannot be quickly dried, and the residual moisture will cause poor sludge dehydration quality and affect the sludge dehydration quality.
