detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1-2, the utility model provides a technical solution: a three-roll press device for dehydrating aquatic plants, including

Distributing roller 1, conveying roller 2, conveying mesh belt 3, pinch roller 4, primary dehydration roller 5, extrusion roller 6, secondary dehydration roller 7, first extrusion spring 8, second extrusion spring 9, scraper Feeder 10, roller body 11 and cutting teeth 12;

The outside of the conveying roller 2 and the first-stage dehydration roller 5 is provided with a conveying mesh belt 3, the top of the left end of the conveying mesh belt 3 is provided with a cloth roller 1, and the top of the conveying mesh belt 3 is provided with a pressure belt near the end of the first-stage dewatering roller 5 Wheel 4, the two ends of the rotating shaft of extrusion roller 6 are provided with first extruding spring 8, the rotating shaft two ends of secondary dewatering roller 7 are provided with second extruding spring 9, and scraper 10 passes through primary dewatering roller 5 and The gap between the secondary dewatering rollers 7 is set between the primary dewatering roller 5 , the squeezing roller 6 and the secondary dewatering roller 7 .
