[0045] The working principle of the above embodiment is:

[0046] When in use, first add the sludge that needs to be concentrated and the protective agent that acts on the sludge into the mixing box 201, then turn on the first motor 203, drive the stirring rod 204 and the stirring blade 205 to rotate, so as to effectively mix the sludge and the protective agent, and then the mixed sludge enters the body 1 through the connecting pipe 208, turn on the second motor 4, and transport the sludge through the stirring roller 5 and the spiral blade 6, and the outer side of the spiral blade 6 is in close contact with the inside of the body 1, thereby effectively reducing the shear force generated by the spiral blade 6 in the process of pushing the sludge, thereby better protecting the nitrifying bacteria, and at the same time, the state of the sludge is monitored in real time through the temperature detector 302 and the pH meter 303.

The sludge is then squeezed and concentrated by the electric push rod 3071 and the extrusion plate 3072. The moisture in the sludge is then discharged through the drain pipe 3077 under the action of the gauze 3075 and the inclined plate 3074.
