Description

Technical Field

[0001] This utility model belongs to the field of material conveying, and in particular relates to a reciprocating screw conveyor. Background Technology

[0002] The sugar-making process from sugar beets includes steps such as juice extraction, purification, evaporation, crystallization, separation of sugar and sugar, and drying. In existing technologies, sugar beets undergo pretreatment before processing, including conveying, impurity removal, and washing. The sugar beets to be processed are stored in the sugar mill's sugar beet pit, with a long, rounded-bottom conveyor leading to the sugar-making workshop. The pit is equipped with a hydraulic flushing device that uses 5-7 times the volume of water as the sugar beets to flush them into the ditch. The ditch is equipped with weeding and stone-removing equipment. After being conveyed and having removed weeds, stones, and other impurities, the sugar beets are sent to a washing tank for further washing to remove surface soil and residual sand and gravel. After washing, the sugar beets need to be shredded to facilitate juice extraction. Commonly used shredders include flat disc type and centrifugal type. Flat disc shredders mainly consist of a vertical shaft and a rotating cutter disc. After the beets are shredded, they need to be squeezed to extract juice using a press. The juice will flow out from the shreds. After the juice extraction, sugary juice will remain on the surface of the shreds, so they need to be rinsed. After rinsing, the shreds are discharged and removed by an auger conveyor. After rinsing, the shreds still have a lot of water. When the auger conveys them out, the conveyor line needs to be extended as much as possible to drain the water from the shreds as much as possible to avoid wasting water and materials. A longer conveyor line occupies more space in the production room and is not convenient to set up. Summary of the Invention

[0003] In view of this, the present invention aims to propose a reciprocating screw conveyor to solve the problem that the existing beet shred waste conveying device has a long conveying line and occupies a large space in the production room.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
