Carbonate cooling and conveying system

The utility model discloses a carbide cooling and conveying system which comprises a first-stage cooling and conveying assembly, a second-stage cooling and conveying assembly and a cooling and storing assembly which are sequentially connected, and the cooling and storing assembly comprises a storing tank body and a cooling jacket arranged on the storing tank body in a sleeving mode. In the conveying process of carbide, the carbide is firstly subjected to two-stage primary cooling conveying and then discharged into the cooling storage assembly, the carbide is stored through the storage tank body, and the carbide is ensured to be fully cooled in the main cooling tank by utilizing various cooling structures arranged on the storage tank body, so that the activity of the carbide is reduced; secondly, the carbide is accumulated at the discharge port and is combined with the discharge valve to form a sealing structure, and internal combustion-supporting gas is replaced by a gas replacement assembly, so that the inte
