Embodiment

[0025] Such as figure 1 Shown, the drying equipment of the sodium thiocyanate of the present embodiment comprises feed inlet 1, first-level drying box 2, microseismic chamber 3, secondary drying box 8, distribution box 5, discharge port 6 and receiving material successively Slot 7. Sodium thiocyanate product is dropped on the primary conveyor belt 9 from feed inlet 1, and it carries sodium thiocyanate and enters the primary drying oven 2 of primary microwave drying for drying, and the microwave intensity of said primary drying oven is 900MHz , The heating time is 40s. After removing most of the water in the first-level drying box, enter the micro-seismic chamber 3 and collide with the micro-seismic screen 4. The micro-seismic screen 4 is placed obliquely at an angle of 12° relative to the horizontal plane and away from the primary conveyor belt 9. One end is higher than the end close to the primary conveyor belt 9, and its vibration intensity is 4. The microvibration screen...

Abstract

The invention discloses equipment and a method for drying sodium thiocyanate. The equipment sequentially comprises a primary drying oven, a micro-vibration chamber and a secondary drying oven. A micro-vibration screen is arranged in the micro-vibration chamber. The method includes primarily feeding the sodium thiocyanate in the primary drying oven, drying the sodium thiocyanate and removing most moisture; smashing the sodium thiocyanate in the micro-vibration chamber by means of vibration for a characteristic of easiness in caking when the sodium thiocyanate is about to be dried; feeding the sodium thiocyanate in the secondary drying oven, drying the sodium thiocyanate to obtain finished products, conveying the finished products by the aid of belts and discharging the finished products from a discharge outlet. The equipment and the method have the advantages that the equipment is high in drying speed and production efficiency as compared with the traditional equipment for drying sodium thiocyanate, energy can be saved, the sodium thiocyanate can be dried uniformly, clean production can be implemented, automatic control is easy to implement, the quality of the products can be improved, and the like.

Description

technical field [0001] The invention relates to a sodium thiocyanate drying equipment and method, belonging to the field of chemical medicine drying. technical background [0002] Sodium thiocyanate is a highly deliquescent and agglomerated product. [0003] In order to prevent deliquescence and agglomeration of sodium thiocyanate, the most important and primary measure is to reduce the moisture content of sodium thiocyanate products, that is, drying. There are many drying methods, whether it is vacuum fluidized bed drying, vacuum rotary kiln drying, or other drying methods, there are certain defects: uneven drying, high energy consumption, environmental pollution, low production efficiency, etc. [0004] Microwave drying is a good choice to overcome the above defects. But in the actual production process, a new problem has appeared: the dry product is easy to form a whole. This is because the crystal water on the surface of sodium thiocyanate contains sodium thiocyanate....
