Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an adjustable vane screw press. Background Technique

[0002] The screw press is a supporting device for a trash rack and is a device that uses physical extrusion for dehydration. It consists of a feed hopper, a pressing screw, a screw tube, a slag discharge pipe, and a driving device. The grid residue fished by the grid or the filter residue after filtration enters the screw tube from the feed hopper and is squeezed and dehydrated under the action of the pressing screw. The water extruded from the material penetrates through the filter screen, converges into the water receiving basin, and is discharged by the drain pipe. After the material is compressed, it is discharged through the slag discharge pipe, thereby greatly reducing the weight and volume of sundries such as grid residue. The screw press is composed of a drainage area, a feeding area, a screw conveying area, and a discharging area. The grid residue enters the feeding area, is compacted in the compaction area by the screw press, and then the grid residue is discharged. The waste liquid flows into the collecting pipe from the grid bars.

[0003] The current screw presses can basically meet people's usage requirements, but there are still some problems, which are specifically described as follows:

[0004] 1. The problem that it is difficult to replace the filter screen of the screw press. After the filter screen is used for a long time, the filter screen will become clogged, affecting the filtration quality. Therefore, it is necessary to replace the filter screen.
