Description

Technical Field

[0001] This utility model relates to the field of alloy processing technology, and in particular to a device for automatic grading and iron removal during the crushing process of crystal materials. Background Technology

[0002] In the preparation of crystalline materials, to reduce the impact of alloys formed by iron, chromium, and aluminum on the quality of the crystalline materials, they are often first crushed and then acid-washed to remove the alloys and other substances that react with the acid. Acid washing can reduce the amount of iron oxide and other substances contained in the crystalline materials. The acid used in acid washing is 5% sulfuric acid or hydrochloric acid. Currently, acid washing is carried out in an acid washing tank. This method of acid washing causes some acid to be discharged due to water vapor generated during the process, thus polluting the environment. Furthermore, the powdery waste crystalline material after acid washing is inconvenient to remove, with most of the waste crystalline material powder settling to the bottom of the acid washing tank, making subsequent cleaning of the acid washing tank difficult. Utility Model Content

Multiple leakage holes are opened on the outer periphery of the pickling bucket 4. A sealing lower frame 41 is provided on the lower wall of the pickling bucket 4. The lower end of the outer wall of the sealing lower frame 41 is the small end, and the outer periphery of the sealing lower frame 41 is in close contact with the inner wall of the sealing frame 20.

[0023] The upper end of the box 2 is provided with a pair of top covers 22 and a pair of L-shaped plates 21. The top covers 22 are inserted into the L-shaped plates 21, and the outer end of the top covers 22 is provided with a pull ring 23.

[0024] Extended guide rods 3 are respectively provided on the upper two side walls of the box body 2. A movable side plate 32 is fitted on each of the extended guide rods 3. A retaining plate 33 is provided on the upper end of the movable side plate 32. A retaining groove is opened on the inner end of the retaining plate 33. A middle plate 34 passes through the inner end of the retaining plate 33. Limiting blocks 36 are provided on the upper and lower walls of the middle plate 34. A concave groove is opened on the inner end of the retaining plate 33. The limiting blocks 36 pass through the concave groove. A motor 35 is installed on the middle plate 34.
