The invention provides a scraper, which is used for a filter tank, wherein a rotating frame is arranged in the filter tank, and the rotating frame can rotate forwards around a first vertical axis to carry out plowing or reversely rotate around the first vertical axis to carry out plowing; the scraper is used for being connected to the rotating frame; when the scraper is connected to the rotating frame, the scraper extends along a second vertical axis and can rotate around the second vertical axis relative to the rotating frame; the scraper is a circular arc plate, and the convex surface of thescraper faces the peripheral wall of the filtering tank. The scraper at least has the following technical effects: (1) compared with a flat plate structure, the circular arc scraper can obviously increase the pressure resistance when discharging grains, and has higher strength; (2) the arc-shaped scraper can ensure that the distances between each point on the scraper and the first vertical axis are as equal as possible in the process of cultivating the grains, thereby avoiding the damage of the scraper to the grains layer in the process of cultivating the grains.
Description
technical field [0001] The invention relates to the technical field of filtration, in particular to a scraper and a filter tank containing the scraper. Background technique [0002] Wort filtration is one of the important links in beer production. At present, most enterprises use lauter tanks for wort filtration. When the wort filtration is finished, the spent grains will be discharged from the waste door driven by the internal scraper waste removal system. The scraper rowing system includes two tiller arms arranged oppositely, and a certain number of scrapers are respectively arranged under the two tiller arms. The scraper rowing system mostly adopts the forward and reverse structure. When rotating forward, the scraper and the cultivator cut the dross layer together to loosen the dross layer (that is, the dregs); when reversing, under the resistance of the wheat dregs, The scraper is opened at a certain angle to push the spent grains out of the grain door (that is, to dis...
