Laminated spiral dewatering equipment having detachable driving device

A laminated spiral dewatering equipment, comprising:

• a filtration cavity;
• at least one spiral shaft;
• a driving device;
• and
• a plurality of supporting plates;
• wherein the plurality of supporting plates are configured to support and position the filtration cavity, the at least one spiral shaft and the driving device;
• the at least one spiral shaft penetrates through the filtration cavity;
• one end of the filtration cavity is configured as a feeding end, and the other end of the filtration cavity is configured as a discharging end;
• the feeding end is provided with a sludge feeding box;
• and the discharging end is provided with a sludge discharging box;
• the filtration cavity comprises a first closed ring piece group consisting of a plurality of first closed ring pieces and a second closed ring piece group consisting of a plurality of second closed ring pieces;
• the second closed ring piece group is different from the first closed ring piece group in motion state;
• a first gasket is provided between adjacent first closed ring pieces and/or a second gasket is provided between adjacent second closed ring pieces;
• a thickness of the first gasket is greater than a thickness of each of the plurality of second closed ring piece, and a thickness of the second gasket is greater than a thickness of each of the plurality of first closed ring pieces such that a gap is formed between adjacent first closed ring pieces and between adjacent second closed ring pieces, respectively;
• the first closed ring piece group is configured to be driven by the driving device to move;
• and the second closed ring piece group is connected to the plurality of supporting plates to keep fixed, or is driven by the driving device to move with a relative displacement with respect to the first closed ring piece group to render the gap unblocked;
• when the number of the at least one spiral shaft is equal to or larger than two, two or more spiral shafts are arranged side by side inside the filtration cavity;
• and a blade of one of adjacent two spiral shafts is close to a central axis of the other of adjacent two spiral shafts;
• the driving device comprises a primary driving rod, a secondary driving rod, a positioning rod, at least one eccentric device and a movable transmission ring;
• the primary driving rod is connected to a drive motor, or the primary driving rod and the at least one spiral shaft share the same drive motor through a transmission mechanism;
• the primary driving rod is supported by at least two of the plurality of supporting plates;
• and the primary driving rod is provided with the at least one eccentric device;
• the primary driving rod is arranged above the secondary driving rod;
• each of the at least one eccentric device is connected to one of the plurality of first closed ring pieces through a driving plate;
• the driving plate is integrally formed with each of the plurality of first closed ring pieces;
• and each of the plurality of first closed ring pieces with the driving plate is configured as the movable transmission ring;
• the secondary driving rod is sleevedly arranged at an upper end of the first closed ring piece group, and the positioning rod is sleevedly arranged at a lower end of the first closed ring piece group, such that the plurality of first closed ring pieces in the first closed ring piece group are connected as a whole;
• and
• the transmission mechanism or the drive motor is connected to the primary driving rod;
• the at least one eccentric device on the primary driving rod is connected to the secondary driving rod through the first closed ring piece group;
• the secondary driving rod is sleevedly arranged in a first avoidance hole of each of the plurality of supporting plates;
• and the positioning rod is sleevedly arranged in a linear limiting hole of each of the plurality of supporting plates.
