Quantitative closed feeding device suitable for comprehensive utilization of byproduct sulfur

The utility model discloses a quantitative closed feeding device suitable for comprehensive utilization of byproduct sulfur, and effectively solves the problems that sulfur raw materials generate relatively large agglomerates in ton bags, and the relatively large agglomerates can increase the material melting time and affect the material melting effect. Comprising a ton bag extruding machine, a sliding rail is arranged above the ton bag extruding machine, a suspension arm is connected to the sliding rail in a sliding mode, a stock bin is arranged on one side of the ton bag extruding machine, the end, away from the ton bag extruding machine, of the sliding rail is located in the stock bin, and a material scattering assembly is arranged at the bottom of the stock bin; a vibrating feeder is arranged below the material scattering assembly, and a bucket elevator is arranged at the discharging end of the vibrating feeder. The secondary scattering device is ingenious in structure and convenient to use, through the a
