[0003] After searching, the publication number is: CN218339891U. A calcination and purification device for calcium oxide, which relates to the field of calcination technology, includes a furnace body, a heating plate is installed inside the furnace body, and a calcination chamber is arranged above the heating plate, a nozzle is installed on the inner wall of the furnace body, and a crushing mechanism is arranged inside the feed pipe; the crushing mechanism includes two groups of bearings connected to the output shaft of the inner wall of the furnace body, and the outer wall of the output shaft is fixedly connected with a crushing roller, the outer walls of the two groups of crushing rollers are provided with crushing teeth, and the rear end of the left output shaft is connected to an output motor, and the front ends of the two groups of output shafts are connected with gears, and the two groups of gears are meshed with each other. The utility model can crush the limestone put into the furnace body by providing a crushing mechanism, thereby reducing the volume of the limestone, increasing its contact area with the flame, and improving the calcination efficiency. At the same time, a guide component is provided, which can evenly disperse the raw materials dropped from the feed pipe to the surroundings, avoid the accumulation of limestone in one place, and ensure the calcination efficiency.

[0004] The existing technology has the following problems:

[0005] Although the above utility model increases the contact area between limestone powder and flame and improves calcination efficiency, it can only produce calcium oxide in batches and cannot produce calcium oxide continuously. Moreover, during the calcination process of a batch of limestone, only the limestone in contact with the flame can easily produce calcium oxide. As for the limestone buried inside, it cannot come into contact with the flame, resulting in low efficiency of batch calcium oxide production.

[0006] To this end, we proposed a calcium oxide calcination and purification device to solve the above-mentioned drawbacks. Utility Model Content
