Reciprocating lamination spiral solid-liquid separator

A reciprocating lamination spiral solid-liquid separator, comprising:

• a support frame (9), a filter chamber (1), a spiral shaft (2) and a driving device (3);
• wherein the filter chamber (1) is assembled with the support frame (9), the spiral shaft (2) is mounted on the support frame (9) and passes through the filter chamber (1), the driving device (3) is mounted on the support frame (9), and two ends of the filter chamber (1) respectively have a feed port (101) and a discharge channel (102);
• wherein the filter chamber (1) includes a first closed movable ring-piece assembly (4) and a second closed ring-piece assembly having a motion state that is inconsistent with a motion state of the first closed movable ring-piece assembly (4);
• wherein the first closed movable ring-piece assembly (4) and the second closed ring-piece assembly are stacked alternately to form the filter chamber (1);
• wherein a gasket (6) is disposed between two adjacent closed ring-pieces of a plurality of closed ring-pieces of at least one of the first closed movable ring-piece assembly (4) and the second closed ring-piece assembly, and a thickness of the gasket (6) is greater than a thickness of the closed ring-piece of another one of the first closed movable ring-piece assembly (4) and the second closed ring-piece assembly, so that a filter gap is formed between the two adjacent closed ring-pieces;
• wherein the first closed movable ring-piece assembly (4) is connected into a whole through a first connection mechanism (7) that passes through the plurality of closed ring-pieces of the first closed movable ring-piece assembly (4), the driving device (3) drives the plurality of closed ring-pieces of the first closed movable ring-piece assembly (4) through a first gearing device (8) to reciprocate a same circular track in all directions, so that a relative displacement occurs between the first closed movable ring-piece assembly (4), the support frame (9) and the adjacent second closed ring-piece assembly, and the filter gap becomes more unobstructed and a filter area of the filter gap is increased.
