Filling device for sodium cyanate production and filling process thereof

Abstract

The invention relates to the technical field of sodium cyanate production, and discloses a filling device for sodium cyanate production and a filling technology thereof.The filling device comprises a discharging hopper, a screw shaft is arranged at the axis of the inner side of the discharging hopper, a discharging opening is fixedly connected to the bottom end of the discharging hopper, a storage box is placed below the discharging opening, and a fixing box is fixedly connected to the outer side of the discharging opening; the bottom end of the fixing box is fixedly connected with a fixing plate located on the outer side of the discharging port, a fixing groove with an opening facing the inner side of the fixing box is formed in the bottom end of the fixing box in the circumferential direction, and the fixing box is slidably connected with a fixing ring through the fixing groove. Through the arrangement of the fixing ring, the air flow on the inner side of the fixing box is increased, air flow increased on the inner side of the fixing box is blown to falling materials on the inner side of the discharging port through the air outlet hole and the air outlet pipe, and therefore air carrying powder materials is prevented from overflowing, material losses in the filling process are reduced, the air flow can be blown back to the inner side of the discharging port again, and the filling efficiency is improved. And part of powder materials driven by the air flow can be recovered in time.

Description

technical field [0001] The invention relates to the technical field of sodium cyanate production, in particular to a filling device for producing sodium cyanate and a filling process thereof. Background technique [0002] The physical and chemical properties of sodium cyanate itself are white crystalline powder. When filling is completed after production and drying, a screw filling machine is usually used to fill the material. The screw filling machine drives the screw to rotate through the main shaft. Move down, so that the powder material is squeezed into blocks while being transported downward, and the main shaft rotates and vibrates at the same time. The material is discharged and filled into the bottom storage box through the discharge port end. After the filling is completed, the spindle drives the screw to stop rotating, and the material is stopped first, and the lower storage box is conveyed by the conveyor belt. Cartridges move into continuous filling. [0003] Wh...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the use of the existing filling device for sodium cyanate production proposed in the background technology, the present invention provides a filling device for sodium cyanate production and its filling process, which has the ability to prevent material splashing , the advantages of high filling efficiency, and solve the technical problems in the above-mentioned background technology that the filling will splash when the material falls and the filling efficiency is low after the material is squeezed by the screw.
