System for separating carbon and sand in sludge carbon and synchronously chambering carbon and working method

The invention discloses a system for carbon-sand separation and synchronous carbon reaming in sludge carbon and a working method.The system comprises a tank body, a rotation starting mechanism, a sludge carbon releasing mechanism, a secondary reverse mixing mechanism and an effluent weir, a sand collecting hopper is installed at the bottom end of the tank body, and the lower end of the sand collecting hopper is connected with a sand discharging pipe; the sludge carbon release mechanism is installed in the tank body and located above the sand collecting hopper, a carbon inlet is formed in the bottom end of the side wall of the sludge carbon release mechanism and externally connected with a carbon inlet pipe, an inlet of the carbon inlet pipe is located outside the tank body, the rotation starting mechanism is installed above the sludge carbon release mechanism, and an inlet of the rotation starting mechanism is externally connected with a water inlet pipe. The secondary reverse mixing mechanism is arranged abo
