[0002] The spiral sludge dewatering machine is a device used to treat sewage sludge. The flocculation reaction is an important step in the sludge treatment process. It is used to aggregate the tiny particles suspended in the sewage into larger agglomerates for easier solid-liquid separation.

A columnar spring 5 is connected to the outside of the sleeve rod 4. The bottom end of the columnar spring 5 is welded to the top of the guide sleeve 3. A driving motor 6 is installed at the bottom of the reaction box 7 by bolts. The power output end of the driving motor 6 is connected to the stirring shaft 20. The stirring shaft 20 is located in the reaction box 7, and a stirring blade 21 is arranged on the periphery of the stirring shaft 20. A strip plate 10 is arranged near the top at one end of the reaction box 7, and a material guide trough 11 is fixed to the top of the strip plate 10 by a locking bolt 12.

A vibration motor 25 is installed at the top of the bottom plate 1 near one end of the guide sleeve 3 by bolts.

[0020] Among them, vertical plates 14 are welded on both sides of the material guide trough 11, the top of the vertical plate 14 is connected to a top plate 15, a servo electric cylinder 16 is installed near the center of the bottom of the top plate 15 by bolts, the power output end of the servo electric cylinder 16 is connected to a first connecting plate 17, the bottom of the first connecting plate 17 is fixed with a second connecting plate 18 by bolts, and the bottom of the second connecting plate 18 is welded with a baffle 19.

[0021] In this embodiment, Figure 1-4 As shown, the servo electric cylinder 16 can conveniently drive the first connecting plate 17 to descend during operation, thereby causing the second connecting plate 18 and the baffle 19 to descend.

[0022] A limiting rod 22 is disposed at one side of the bottom end of the material guide groove 11 , a limiting groove 23 is disposed at one end of the reaction box 7 , and an end of the limiting rod 22 is located in the limiting groove 23 .
