[0002] The production process of silicon carbide micropowder includes the following steps: primary crushing, screening, shaping, pickling, grinding, grading, and secondary grading. During the production of silicon carbide micropowder, various impurities, such as iron powder or iron filings, must be removed. The main technical means of removing iron-containing impurities in the prior art is to use pickling to react the iron or other impurities in the powder or slurry with sulfuric acid to form ferric sulfate and a salt solution soluble in water. The solution is then separated from the powder by precipitation, thereby separating the iron or other impurities from the powder or slurry.

[0027] The utility model provides a technical solution: Example 1

[0028] Combine Figures 1 to 4 A pickling and grinding device for processing silicon micropowder for dry-type transformers includes a base 3, a pickling and grinding device 4 is fixedly connected to the top of the base 3, a driving mechanism 1 is provided in the base 3, and a supporting mechanism 2 is provided on the top of the driving mechanism 1.

[0029] The driving mechanism 1 includes a driving component 11, a transmission component 12 and an adjustment component 13. The driving component 11 is arranged in the base 3, the transmission component 12 is arranged in the base 3 on the left and right sides of the driving component 11, and the adjustment component 13 is arranged on the front and back sides of the transmission component 12.

[0030] The driving assembly 11 includes a dual-axis motor 1101, which is fixedly connected to the base 3. The dual-axis motor 1101 is fixedly connected to a rotating shaft 1102 on both sides. The outer side of the rotating shaft 1102 is fixedly connected to a bevel gear 1 1103. The rotating shaft 1102 is rotatably connected to the base 3. A groove is provided in the base 3 corresponding to the position of the bevel gear 1 1103. The transmission assembly 12 includes a bevel gear 2 1201. The bevel gear 2 1201 is meshed with the rear side of the outer ring of the bevel gear 1 1103. The inner ring of the bevel gear 2 1201 is fixedly connected to the rotating shaft 1202. The front and rear sides of the outer ring of the rotating shaft 1202 are fixedly connected with a worm 1203, and the rotating shaft 1202 is rotatably connected to the base 3. The base 3 is provided with grooves corresponding to the positions of the bevel gear 2 1201 and the worm 1203. The adjusting component 13 includes a worm gear 1301, which is engaged with the outer ring of the worm 1203. The inner ring of the worm gear 1301 is fixedly connected to a threaded rotating cylinder 1302, and the inner ring of the threaded rotating cylinder 1302 is threadedly connected to a threaded rod 1303. The threaded rotating cylinder 1302 is rotatably connected to the top of the base 3, and the base 3 is provided with a groove corresponding to the position of the worm gear 1301.

[0031] Furthermore: the staff only needs to start the dual-axis motor 1101 to control the support drums 2104 at the four corners to move up and down synchronously, so that the support drums 2104 at the four corners can maintain a uniform horizontal height to support the pickling and grinding equipment 4, thereby increasing the stability of the pickling and grinding equipment 4 when the device is in use, and when it is necessary to disassemble or repair the pickling and grinding equipment 4 or the internal structure of the pickling and grinding equipment 4, the staff can also control the support drum 2104 downward to release the connection with the pickling and grinding equipment 4, which is convenient for the staff to operate. Example 2

[0032] See Figures 1 to 4 , and on the basis of Example 1, it is further obtained that the support mechanism 2 includes a support component 21 and a limit component 22, the support component 21 is arranged at the top of the adjustment component 13, and the limit component 22 is arranged at the bottom of the support component 21.

[0033] The support assembly 21 includes a movable seat 2101, which is fixedly connected to the top of the threaded rod 1303. The left and right sides of the top of the movable seat 2101 are fixedly connected to a fixed frame 2102. The inner side of the fixed frame 2102 is fixedly connected to a fixed shaft 2103. The outer ring of the fixed shaft 2103 is rotatably connected to a supporting drum 2104. The top of the supporting drum 2104 fits into the bottom of the pickling and grinding equipment 4. The limiting assembly 22 includes a telescopic rod 2201, which is fixedly connected to the four corners of the bottom of the movable seat 2101. The bottom of the telescopic rod 2201 is fixedly connected to a limiting slider 2202, and the limiting slider 2202 is slidably connected to the base 3.

[0034] Furthermore: the limiting slider 2202 is slidably connected to the top of the base 3, and cooperates with the telescopic rod 2201 to limit the movable seat 2101, so that the movable seat 2101 cannot rotate on its own during the lifting process, thereby ensuring the connection between the threaded drum 1302 and the threaded rod 1303 during rotation, and ensuring the stability of the movable seat 2101 during the lifting process. The supporting drums 2104 at the four corners support the bottom of the pickling and grinding equipment 4, reducing the gravity traction on the pickling and grinding equipment 4 during use, and reducing the possibility of deformation of the pickling and grinding equipment 4.

[0035] In actual operation, when this device is used, when it is necessary to support the pickling and grinding equipment 4, the staff first starts the dual-axis motor 1101. The dual-axis motor 1101 starts and drives the bevel gears 1103 on the left and right sides to rotate synchronously through the rotating shaft 1102. The bevel gears 1103 on the left and right sides rotate synchronously through the bevel gear 2 1201 and the rotating shaft 1202, and the worms 1203 at the four corners rotate synchronously. The worms 1203 at the four corners rotate synchronously through the worm gear 1301 and drive the threaded drums 1302 at the four corners to rotate synchronously. The synchronous rotation of 302 drives the threaded rods 1303 at the four corners to move upward synchronously. The synchronous upward movement of the threaded rods 1303 at the four corners drives the supporting rotating drums 2104 at the four corners to move upward synchronously through the moving seat 2101. The supporting rotating drums 2104 at the four corners move upward synchronously and contact the bottom of the outer ring of the pickling and grinding equipment 4. Then the dual-axis motor 1101 is turned off. At this time, the worm 1203, the worm wheel 1301 and the threaded rotating drum 1302, and the threaded rod 1303 all complete the fixation of the position of the moving seat 2101 through threaded self-locking, and the support of the pickling and grinding equipment 4 is completed at this time.
