Description

Technical Field

[0001] The utility model relates to the technical field of zinc sulfate production, in particular to a pulverizing device used for solid zinc sulfate production. Background Art

[0002] Zinc sulfate is the main raw material for making zinc barium white and zinc salts. It can also be used as a mordant for printing and dyeing, a preservative for wood and leather, and an important auxiliary raw material for producing viscose fiber and vinylon fiber. In addition, it is also used in electroplating and electrolysis industries, and can also be used to manufacture cables.

[0003] Powdered solid zinc sulfate is very easy to deliquesce in the air and forms hard agglomerates. In order to facilitate subsequent processing, the agglomerates need to be crushed and screened to obtain zinc sulfate powder. In the prior art, for example, the utility model patent with patent number CN212040853U discloses a device for crushing agglomerated zinc sulfate, which is placed on a screen plate, and the U-shaped plate is driven down by starting an electric push rod to adjust the distance between the rolling roller and the screen plate, and the driving motor is started to drive the rolling roller to rotate at the same time to roll and crush the agglomerated zinc sulfate, and the servo motor is started to drive the rotation of the cam, and the screen plate is driven to vibrate back and forth through the spring and the roller, and the vibration motor is started on the screen plate, so that the agglomerated zinc sulfate is rolled and crushed, and the crushed zinc sulfate falls quickly from the screen plate from the funnel into the collection box, which can increase the efficiency of rolling and crushing, and the interaction between the back and forth movement of the screen plate and the rolling roller also makes the rolling and crushing efficiency higher.

[0004] However, in the above-mentioned prior art, the agglomerated zinc sulfate is only crushed and sieved, but is not dried in time, and the moisture absorbed by the zinc sulfate is not removed. Even if appropriate preservation measures are adopted, there is still a risk of agglomeration, which makes the zinc sulfate face problems such as agglomeration, uneven particles, reduced storage stability and reduced product quality during storage and subsequent applications.

[0005] Based on this, it is necessary to study a crushing equipment for the production of solid zinc sulfate. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a pulverizing device for the production of solid zinc sulfate, which can effectively solve the problem that the agglomerated zinc sulfate is not dried in time after crushing, resulting in easy re-agglomeration and uneven particles.
