Detailed Description

The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings.

Example 1

As shown in fig. 1-3, a dewatering extruder comprises a box body 1, the inner bottom surface of the box body 1 is an inclined plane with a high end and a low end, a spiral elevator 2 is arranged at the bottom of the inner side of the box body 1 along the bottom surface of the box body 1, the top of the box body 1 is provided with an opening, a scum scraper device is arranged at the opening of the top of the box body 1, the box body 1 is provided with a feed inlet 3 and an overflow outlet 4, and a discharge outlet of the spiral elevator 2 is provided with a spring extrusion device.

The scum scraper device comprises a driving wheel 11, a driven wheel 12 and a chain 13 arranged on the driving wheel 11 and the driven wheel 12, wherein at least one scraper 14 is arranged on the outer side of the chain 13, and the driving wheel 11 is driven by a scum scraper driving motor 15.

Two scrapers 14 are mounted on the outer side of the chain 13, and the two scrapers 14 are uniformly distributed along the chain 13.

The spring extrusion device comprises a spring pressing plate 21, a supporting rod 22 and a spring 23, wherein the spring pressing plate 21 is arranged at a discharge hole of the spiral elevator 2, the supporting rod 22 is fixed on the outer side of the spring pressing plate 21, the spring 23 is sleeved outside the supporting rod 22, one end of the spring 23 is fixed with the spring pressing plate 21, the other end of the spring 23 is fixed with the outer end part of the supporting rod 22, and the outer end part of the supporting rod 22 is fixed with the box body 1.
