Environment-friendly quick-replacement segmented type iron tap channel

The utility model relates to an environment-friendly quick-replacement segmented type iron tap channel. The environment-friendly quick-replacement segmented type iron tap channel comprises an outer layer and a segmented type wear-resistant layer. Protruding strips are arranged on the outer wall of the segmented type wear-resistant layer. Grooves matched with the protruding strips are formed in the inner wall of the outer layer. A high-temperature demolding layer is arranged between the outer layer and the segmented type wear-resistant layer and extends to the spaces between the protruding strips and the grooves. The segmented type wear-resistant layer is adopted, and damaged parts of the wear-resistant layer can be conveniently replaced; the space between the outer layer and the segmented wear-resistant layer is provided with the protruding strips and the grooves, wherein the protruding strips and the grooves are matched and embedded, and therefore the tightness of the outer layer and the segmented type wear-resistant layer can be enhanced, the outer layer and the segmented type wear-resistant layer are not prone to the disengagement and falling phenomena, and the safety degree of the outer layer is ensured. The high-temperature demolding layer is arranged between the outer layer and the segmented type wear-resistant layer, the wear-resistant layer can be rapidly demolded through the high-temperature demolding layer, and replacement is convenient.
