Description

Double-action ring laminated solid-liquid separation device

[Technical Field]

The invention belongs to a solid-liquid separation device, in particular to a double-action ring laminated solid-liquid separation device.

【Background technique】

The prior art laminated spiral sludge dewatering machine is a filtering cavity formed by laminating a fixed ring and a movable ring. The fixing ring is fixed on the pillar and remains in a fixed state, depending on the activity of the movable ring and the fixing ring. A change in the position of the overlap occurs, keeping the filter slit unobstructed. However, since the filter body is only active, the positional change between the movable ring and the fixed ring is relatively simple and to a lesser extent.

In addition, the Chinese invention patent 201710832445.X discloses a dehydrator for a torsional pendulum movement, which uses the same motor to drive the screw shaft and the support rod to drive the screw shaft and the drive rod for driving the support rod. This method can indeed play a role in energy saving to a certain extent. However, in the implementation process, the driving structure is complicated, not only to avoid more avoidance problems in design, but also to leave more space for protecting the gears. The real need to achieve solid-liquid separation is to discharge the filtrate quickly and in a timely manner as the screw shaft rotates to push the solid-liquid mixture forward. When driven by a motor, the torsion frequency of the support rod will be restricted by the rotation speed of the screw shaft, which will affect the effect of water filtration.
