Description

Technical Field

[0001] The invention relates to the technical field of sodium dithionite processing, in particular to a sodium dithionite drying and feeding device. Background Art

[0002] Sodium dithionite is a basic inorganic chemical raw material, mainly used for food bleaching, printing and dyeing auxiliaries, pharmaceutical production, water treatment and pollution control. In the processing and production of sodium dithionite, the produced sodium dithionite often absorbs moisture and becomes damp due to being placed in the air for a long time or standing in a humid environment. Sodium dithionite is a strong reducing agent with unstable aqueous solution properties. When it absorbs too much moisture, if it is directly put into use, it is easy to heat up and cause spontaneous combustion, causing unnecessary losses. Therefore, before the processing and use of sodium dithionite, it needs to be dried. At present, a relatively low temperature hot air source is mostly used for drying.

[0003] For example, Chinese patent publication number CN205747905U discloses a sodium dithionite drying feeding device, which includes a mounting base and a mounting plate, a mounting plate is provided above the mounting plate, a connecting channel is embedded on the mounting plate, a drying drum No. 1 and a drying drum No. 2 are rotatably connected between the upper and lower ports of the connecting channel, a material receiving channel is provided on the mounting base at the lower left end of the drying drum No. 2, the drying drum No. 1 and the drying drum No. 2 are fixedly connected to the connecting channel through a connecting bearing, the upper port of the connecting channel is connected to the outer ring of the connecting bearing, the lower end of the drying drum No. 1 is connected to the inner ring of the connecting bearing, the drying drum No. 1 and the drying drum No. 2 are both provided with gear rings, a driving motor is provided on the connecting channel close to the gear ring, an active gear is provided at the output end of the driving motor, and the active gear is meshed with the gear ring.
