Reaction still lining

The invention discloses a reaction still lining and relates to the technical field of reaction still manufacture. The reaction still lining comprises a shell provided with an upper shell cover. A lining rubber plate is arranged on the inner surface of the shell. Multiple vertical locating strips are arranged at intervals at the positions, close to the upper shell cover, of the edge of the lining rubber plate. Multiple vertical locating grooves are distributed circumferentially in the positions, close to the upper shell cover, of the inner surface of the shell. Compared with the prior art, the locating strips on the edge of the lining rubber plate can be placed one by one in the vertical locating grooves in the inner surface of the shell, and therefore the lining rubber plate can be spliced accurately in a time saving mode. 本发明公开了一种反应釜衬里，涉及反应釜制造技术领域，包括设有上封头的壳体，在所述壳体的内表面设有衬里橡胶板，所述衬里橡胶板于近所述上封头的边缘处间隔设有多根竖直的定位条；所述壳体于近所述上封头的内表面上呈圆周分布有多个竖直定位槽。较之现有技术，本发明可以将衬里橡胶板上边缘的定位条逐个放入壳体内表面的竖直定位槽中，即省时又能准确拼装衬里橡胶板。
