When the hot air blower 8 works, the air in the treatment tank 1 is heated, so as to dry the sludge. The air enters from the air inlet pipe 9, passes through the hot air blower 8, and flows out from the air outlet pipe 10, so that the air is circulated and heated, improving the thermal efficiency.

[0023] The anti-blocking mechanism includes a servo motor 12, a lead screw 13, a slider 14 and a push plate 15.
