Description

Technical Field

[0001] The utility model relates to a material storage and discharging device. Background Art

[0002] The production of carbon molecular sieves involves two continuous processes: extrusion and carbonization. Powdered raw materials are mixed with tar to form a dough, which is then extruded under high pressure and then carbonized at high temperatures to form a solid structure. The material is transported from the extrusion station to the carbonization station in turnover drums (φ1mm*1.2m).

[0003] The extrusion and carbonization processes are located in different workshops. The specific process is as follows: the product extruded from the extrusion station falls directly into the turnover barrel below the discharge port. Once the barrel is full, the operator pushes the turnover barrel to the carbonization workshop. Using the crane, the turnover barrel is lifted and transported to the large storage bin (2m*6m*2m) at the front of the carbonization furnace. The storage bin is divided into three areas, each separated by partitions. The bottom of each area has a conical structure, and the unloading is controlled by pneumatic valves.

[0004] Based on the above storage method and tank structure, due to workshop height and site restrictions, coupled with poor material flowability (wet materials), the silo cannot be built high or large enough, resulting in limited transit storage capacity, which constrains production plans. Furthermore, the lifting and lowering of the turnover barrels is labor-intensive (climbing up and down via a fixed escalator). The square structure of the storage silo, especially the four-sided pyramid structure at the bottom, negatively affects the material's flowability. Operators often need to climb up the tank, use long poles to clear it, and simultaneously hit the tank hard, causing material to shatter. This increases employee workload and affects product loss and quality. Utility Model Content
