[0002] Sludge treatment is the process of reducing, stabilizing and harmless sludge by concentrating, conditioning, dehydrating, stabilizing, drying or incinerating. The method of sludge treatment mainly depends on the water content of the sludge and the final disposal method.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the sludge treatment centrifugal filter device with anti-jamming function:

[0019] 1. The stirring mechanism facilitates the dilution of the sludge in the outer shell. Blockages often occur during the use of existing sludge treatment equipment. The blockage is generally caused by the high viscosity of the sludge, which leads to blockage of the discharge port. The motor is started. When the sludge enters the outer shell and falls from the annular holes on the surface of the support plate, the support plate slows down the falling rate of the sludge, making it convenient to stir in the outer shell. The stirring rod fixedly connected to the second surface of the connecting shaft stirs the sludge that falls into the outer shell, so that the upper and lower layers of sludge are evenly mixed, thereby preventing blockages caused by the high viscosity of the sludge.

[0020] 2. The heating mechanism further increases the viscosity of the sludge in the outer shell. The dilution of the sludge can also reduce its viscosity by heating. During the stirring of the sludge in the outer shell, the heat source is started. Since the sludge is a non-Newtonian liquid, the fluidity of the sludge increases when heated. Therefore, under the heating effect of the heat source and the rotation of the rotating plate, the speed recorder will record the speed of the rotating plate and transmit the electrical signal to the control switch. The higher the speed, the higher the fluidity at this time. The control switch then controls the heating intensity of the heat source to automatically decrease, thereby automatically changing the heating intensity of the heat source according to the viscosity of the clay, thereby saving electricity.
