The cross section of the inner cavity of the recovery cylinder adopts an ellipse shape, and the volume of the inner cavity of the recovery cylinder can be increased on the premise of avoiding stress concentration, thereby improving the utilization rate of the recovery cylinder.

Preferably, the recovery cylinder is made of spheroidal graphite cast iron, and the base is made of spheroidal graphite cast iron, so that the service lives and corrosion resistance of the recovery cylinder and the base are ensured.

Preferably, a resin sand layer with the thickness of more than 30mm is paved at the joint of the bottom surface of the recovery cylinder and the groove. The resin sand layer can resist high-temperature residual molten iron soup, and blocks gaps between the bottom surface of the recovery cylinder and the base, so that a better water leakage preventing effect is achieved. And the resin sand layer can ensure the purity of the recovered iron ingot, and the furnace return use of the iron ingot is not affected.

Preferably, the inner wall of the recovery cylinder is coated with a paint layer. The coating layer can further improve the demolding effect, and the coating layer can be repeatedly and automatically painted as required.

Compared with the prior art, the utility model has the following advantages: the residual soup recycling device for casting and pouring adopts a split design consisting of the recycling bin and the base, has the advantages of simple structure, convenient assembly and large capacity, can greatly improve the repeated use times and the service life of the device, and saves the cost. When the iron ingot casting machine is used, residual iron liquid residual soup after casting is poured into the recovery cylinder, after the residual soup collected in the recovery cylinder reaches a certain amount and is solidified into an iron ingot, the recovery cylinder is lifted and inverted, so that the upper opening of the recovery cylinder faces downwards, and the solidified iron ingot can be conveniently separated from the recovery cylinder under the action of dead weight due to the fact that the inner wall of the recovery cylinder is provided with a certain inclination, and the iron ingot can be knocked downwards to be smoothly separated.
