[0015] The advantages of the present invention are:

[0016] 1. The sludge to be dehydrated enters the connecting sleeve through the feed pipe, and the power bearing bracket assembly provides power to drive the rotating sleeve to rotate, and then the rotating sleeve drives the spiral blade to rotate. The spiral motion of the spiral blade drives the sludge. When the sludge contacts the turnover sleeve, water falls into the dewatering box through the through hole 1. The dehydrated sludge is discharged through the mud outlet hole under the action of the spiral blade, and the sludge dehydration is completed; at the same time, the sludge discharged through the mud outlet hole is blocked by the mud guard and the extrusion plate push spring, and is stacked between the mud guard and the dewatering box to form a The sludge is fully dehydrated under the resistance of the fender and the extrusion plate push spring. At the same time, the threaded extrusion rod can be rotated according to the actual situation, and the extrusion plate is driven by the threaded extrusion rod to adjust the compression of the extrusion plate push spring, thereby increasing the resistance applied to the sludge by the fender and improving the sludge dehydration effect. At the same time, the execution motor drives the matching roller to rotate, and then drives the matching ring to rotate through the matching roller, and then drives the rotating sleeve to rotate through the matching ring, so that the sludge in the rotating sleeve is better dehydrated under the action of centrifugal force.

[0017] 2. Start the second execution motor, and drive the rotating sleeve to rotate through the second execution motor, thereby providing power for sludge dehydration;

[0018] 3. When the sludge is dehydrated, the executive motor 2 drives the rotating sleeve to rotate forward. At this time, the rotating sleeve drives the connecting pipe A to rotate and makes the one-way ratchet rotate forward. At this time, the one-way ratchet lever does not brake the one-way ratchet in the lever retaining spring, ensuring the normal completion of sludge dehydration. At the same time, the damping slide bar acts in the annular damping groove to prevent the connecting pipe B from rotating. When the sludge dehydration is completed and the sludge dehydration component needs to be cleaned, the executive motor 2 is started in the reverse direction and drives the rotating sleeve to rotate in the reverse direction. At this time, the one-way ratchet lever brakes the one-way ratchet in the lever retaining spring, thereby making the connecting pipes A and B rotate at the same time, and then the spiral slide groove acts on the one-way ratchet. Under the action of the one-way end cover of the liquid outlet, the water in the water tank flows into the connecting pipe B and the connecting pipe A in one direction through the water pipe, and finally enters the inner cavity 1. Under the action of the internal pressure, the water is sprayed out through the multiple one-way opening holes C between the rotating sleeve and the spiral blades, so as to clean the dehydration box body, the end cover of the dehydration box body, the rotating sleeve, the circulating sleeve and the spiral blades, and flows out through the drainage hole on the dehydration box body to complete the cleaning.
