Description

Technical Field

[0001] The utility model relates to the technical field of fly ash chelating agent preparation, in particular to a separation device for fly ash chelating agent preparation. Background Art

[0002] Chelation is widely used in chemical research and industrial production. Adding a chelating agent to form chelates with completely different properties from metal ions is a primary method for reducing and controlling metal ion concentrations. Fly ash chelating agents, in particular, possess extremely strong heavy metal chelating properties, reacting at room temperature and across a wide pH range. They are unaffected by heavy metal content and complex formation. Their ease of use, excellent treatment results, and low processing costs have led to their widespread application in heavy metal stabilization in incineration fly ash. During the preparation process, fly ash chelating agents require separation of impurities from the raw materials.

[0003] Patent announcement number CN221714816U discloses a separation device for preparing fly ash chelating agents, which separates fly ash chelating agents by means of a sieve plate arranged on a connecting shaft at the bottom end of a motor. The sieve plate is driven by the motor to rotate in different directions, so that the material can vibrate on the sieve inside the sieve plate, thereby filtering out small particles. In this way, the two substances are separated. The working process is simple, convenient, and fast for separating the fly ash chelating agents, and it is also convenient for staff to operate. However, when the separation device for preparing fly ash chelating agents is in use, the chelating agent raw material therein will pass through the sieve under the action of gravity and be separated from impurities. The separation rate is relatively slow, and the impurities are easily spread and blocked on the sieve, preventing the raw material from falling, thereby reducing the separation efficiency of the device.
