[0002] During the sludge treatment process, an incinerator is needed to burn and dry the sludge to reduce the volume of the sludge, making it more convenient for subsequent treatment. During the incineration process, a large amount of flue gas will be generated and discharged along the exhaust pipe. However, the incineration of the sludge causes more dust in the flue gas. If these dusty flue gases are discharged directly, it will not only affect the air and increase the workload of subsequent treatment equipment, but also separate the floating dust from the incinerated sludge, making it inconvenient to centrally treat the incinerated sludge.

[0022] The top of the incinerator 1 is fixedly connected with a crushing bin 2, the right side of the crushing bin 2 is fixedly connected with a servo motor 11, the output shaft of the servo motor 11 is fixedly sleeved with a first crushing roller 12, the left side of the first crushing roller 12 is fixedly connected with a gear assembly 13, and the right side of the gear assembly 13 is provided with a second crushing roller 14;

[0023] The servo motor 11 is started to drive the first crushing roller 12 to rotate. When the first crushing roller 12 rotates, the gear assembly 13 is driven to operate, and then the second crushing roller 14 is driven to rotate through the gear assembly 13, so that the sludge is crushed by the first crushing roller 12 and the second crushing roller 14, and the crushed sludge enters the inner cavity of the incinerator 1 for incineration, thereby avoiding the situation where larger lumps in the sludge affect the incineration efficiency.

[0024] The spring assembly 8 is composed of a damping telescopic rod and a spring, and the damping telescopic rod is located at the center of the spring cavity;

[0025] By setting the spring, the filter plate 9 can vibrate when struck by the striking head 6, thereby shaking off the dust, and then the filter plate 9 is positioned and guided by the damping telescopic rod to avoid the filter plate 9 from shifting during vibration and improve the stability during vibration.

[0026] The knocking head 6 is conical, and the knocking head 6 contacts the bottom of the filter plate 9;

[0027] The striking head 6 is conical, so that the protrusion of the striking head 6 can displace the filter plate 9, and the striking head 6 is in contact with the bottom of the filter plate 9, so that when the striking head 6 rotates, it can stably drive the filter plate 9 to shake.
