It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
On the contrary, this application is intended to cover any alternatives, modifications, equivalents, and alternatives that may be included within the spirit and scope of the application as defined by the appended claims. Furthermore, in the following detailed description of the present application, certain specific details are set forth in order to provide a better understanding of the present application. It will be apparent to one skilled in the art that the present application may be practiced without these specific details.
The wear-resistant structure of the sludge discharge passage for the centrifugal concentrator according to the embodiment of the present application will be described in detail with reference to fig. 1 to 3. It is to be noted that the following examples are only for explaining the present application and do not constitute a limitation to the present application.
In an embodiment of the present application, as shown in fig. 1-2, a wear-resistant structure of a sludge discharge channel for a centrifugal concentrator may include a centrifugal concentrator body, an L-shaped sludge discharge channel is provided in a concentrating end of the centrifugal concentrator body, and further includes: the wear-resisting ring 2 is arranged at the corner of the L-shaped sludge discharge channel and is fixedly arranged on an end cover 1 of a concentrating end rotary drum 7 of the centrifugal concentrator body; the wear-resistant ring 2 is made of ceramic, although the wear-resistant ring 2 can also be made of tungsten carbide, but tungsten carbide is expensive in manufacturing cost and not beneficial to marketization, and compared with the tungsten carbide, the ceramic is much cheaper in price and has the same wear-resistant effect. Wear-resisting ring 2 is the annular, and is glued through the structure by a plurality of ceramic ring bodies 6 and forms, easy to assemble and change. As shown in fig. 3.
The wear-resistant plate 4 is arranged on the inner wall of a rotary drum 7 of the centrifugal concentrator body close to the wear-resistant ring 2; the wear-resistant ribs 5 are arranged on the inner wall of a rotary drum 7 of the centrifugal concentrator body, and the wear-resistant ribs 5 and the wear-resistant plates 4 form a convex prism-shaped structure.
In some embodiments, the wear-resistant plate 4 is made of ceramic, and the wear-resistant plate 4 is annular and fixed on the inner wall of the drum 7 by structural adhesive; and a plurality of limiting grooves used for limiting the wear-resistant ribs 5 are formed in the wear-resistant sheet 4 along the thickness direction.
