The utility model relates to old sand recycling processing technical field, and disclose a sand casting old sand processing device, including work bench and fixed in the feeding seat of work bench top side, the one side of feeding seat is installed with power motor, and power motor is fixed on work bench, the output of power motor is rotatably connected with broken roll, and broken roll rotatory installation is in feeding seat, can stir the material after crushing in the blanking cylinder, thereby is favorable to accelerate the material after crushing and fall, avoid the possible that material is accumulated and is blocked in blanking cylinder, thereby is favorable to improve the effect that device handles, reduces the trouble of manual shutdown dredging simultaneously, lets the sieve plate have vibration effect when moving screening simultaneously, is favorable to improve the effect that sieve plate screens, thereby is favorable to improve the effect that device handles, the vibration of sieve plate relies on automatic realization when moving sieve plate, improves the efficiency simultaneously, can also reduce the use consumption of external power equipment.

The application relates to the technical field of energy-saving equipment, in particular to a hot air circulating heating fan and an oven, which comprises a center pipe fixedly connected in an inner container, a frame fixedly connected outside the inner container, a motor x fixedly connected on the frame, a fan blade rotatably connected on the frame, a heating sheet arranged in the center pipe, a suction device fixedly connected on the inner container, a mounting frame fixedly connected in the center pipe, and an inclined plate rotatably connected on the mounting frame. The application uses a sensing control device to detect the smoke when the suction device in the circulating air flow is used, and when the food is burnt, the operation mode of the application can be switched, the heating air flow and the circulating air flow are stopped, and the air flow containing the smoke is discharged outward, so that the abnormal energy consumption of the application is reduced, the cleaning work caused by the smoke accumulation is reduced, and the use effect of the application is improved.
