[0044] Specifically, the scraper base includes an inner ring plate 1-1, an outer ring plate 1-2 arranged on the outer periphery of the inner ring plate 1-1, a plurality of connecting seats 1-3 arranged between the inner ring plate 1-1 and the outer ring plate 1-2, and a scraper mounting seat 1-4 fixed on the outer ring plate 1-2, and a plurality of scrapers 1-5 are detachably connected to the scraper mounting seat 1-4.

[0045] In this example, the silo body 7 is a cylindrical tank structure, and the multiple scrapers 1-5 are arc-shaped to match the inner wall of the silo body 7. The multiple scrapers 1-5 are arranged in sections on the scraper mounting seat 1-4 and are arranged in an arc-shaped structure to match the inner wall of the silo body 7.

[0046] Among them, the inner ring plate 1-1 is in a circular ring shape, the outer ring plate 1-2 includes an arc portion 1-2a and a straight plate portion 1-2b arranged concentrically with the inner ring plate 1-1, the scraper mounting seat 1-4 is fixed on the arc portion 1-2a, and the straight plate portion 1-2b forms an avoidance opening to avoid the steam explosion mechanism (not shown) installed at the feed port 7-1 of the silo body 7.
