Description

Technical Field

[0001] The utility model relates to the technical field of precipitation and impurity removal, in particular to a zinc oxide powder precipitation and impurity removal device. Background Art

[0002] Zinc oxide, as the name suggests, is an oxide of zinc. It is insoluble in water and ethanol, but soluble in acid, aqueous sodium hydroxide solution, and ammonium chloride. It is a commonly used chemical additive. In the production process of zinc oxide, it is very easy to carry in a lot of iron impurities. Therefore, in order to improve the purity of zinc oxide, the iron impurities are generally removed by solution precipitation. Zinc oxide is placed in a solution containing specific substances, and the substances in the solution will react with the iron impurities to form a precipitate, which can then be separated from the precipitate.

[0003] However, when using this solution precipitation method, it was found that since a part of the precipitate would directly adhere to the wall of the sedimentation barrel, after the precipitate was taken out, the barrel still contained a part of iron impurities, which would directly affect the next precipitation and impurity removal work. Subsequently, the barrel wall had to be cleaned manually with a handheld scrubbing tool, which was a more troublesome operation.

[0004] Therefore, it is necessary to provide a new zinc oxide powder precipitation and impurity removal device to solve the above technical problems. Utility Model Content

The movable plate 7 can only form a linear lifting path, and a connecting plate 8 is fixedly installed at the bottom of the sliding plate 7, and a rodless cylinder 9 is fixedly installed at the bottom of the connecting plate 8, and a cross-bar 10 is fixedly installed on the slider thereon, and a connecting rod 11 is fixedly installed at the bottom of the cross-bar 10, and a pressing plate 12 is fixedly installed at the bottom end of the connecting rod 11. The diameter of the pressing plate 12 is adapted to the inner diameter of the sedimentation barrel 2, so that the attachments on the inner wall of the sedimentation barrel 2 can be scraped off. In order to drive the vertical screw 6 to rotate, a motor 1 is fixedly installed on the top of the support seat 4, and its output shaft is fixedly connected to the top of the vertical screw 6.

[0022] In the above-mentioned manner, in order to load the sediment, a movable groove is opened on the base 1, and a slag car located below the sedimentation barrel 2 is arranged in the movable groove.

[0023] The scraper 19 is driven by the push rod 16 to move horizontally, thereby scraping off the residue at the bottom of the pressing sheet 12. In addition, a motor 2 is fixedly installed on the outer wall of the concave frame 15 close to the support seat 4, and its output shaft is fixedly connected to one end of the transverse screw 16.

[0024] In this method, in order to drive the bottom plate 3 to rotate, the bottom port of the sedimentation barrel 2 is opened, and a frame 13 is fixedly installed on the top of the base 1, in which a transmission shaft 14 is rotatably installed, and the top of the transmission shaft 14 is fixedly connected to the bottom plate 3. In addition, a motor three is fixedly installed on the outer wall of the frame 13 on the side away from the support seat 4, and gears are fixedly sleeved on the output shaft and the transmission shaft 14, and the two gears are meshed.

[0025] In this embodiment, in order to fix the sedimentation barrel 2, a connecting frame is fixedly installed on one side of the support seat 4, one side of the connecting frame is fixedly connected to the sedimentation barrel 2, and a drain pipe is fixedly installed on the sedimentation barrel 2, and a valve is provided on the drain pipe.

[0026] The working principle of the zinc oxide powder precipitation and impurity removal device provided by the utility model is as follows:

[0027] When precipitating and removing iron impurities in zinc oxide, the zinc oxide is poured into a specific solution and waited for reaction. The final precipitate is the iron impurity precipitate. Then, the valve is opened and the upper solution is discharged through the drain pipe.

[0028] After the upper solution is discharged, the motor three is started in the forward direction. Through the meshing between the two gears, the transmission shaft 14 can be driven to rotate, thereby being able to rotate with the bottom plate 3. During the rotation process, the bottom port of the sedimentation barrel 2 is gradually opened, and the sediment will automatically flow out along the opened port and flow into the slag car until the bottom plate 3 rotates 90°. Then, the motor three is turned off, and then the rodless cylinder 9 is started first. The slider on it moves horizontally with the cross-bar 10, and finally the pressing sheet 12 is moved to the top of the sedimentation barrel 2. Then, the motor one is started in the forward direction, and its output shaft drives the vertical lead screw 6 to rotate. Through the threaded cooperation between it and the sliding plate 7, the pressing sheet 12 can be lowered. When the pressing sheet 12 drops into the sedimentation barrel 2 , it will contact the inner wall of the sedimentation barrel 2, thereby scraping off the sediment attached thereto and scraping it into the slag car, until the pressing sheet 12 drops to the bottom, and then turn off the motor one. At this time, the bottom end surface of the pressing sheet 12 is flush with the bottom end surface of the sedimentation barrel 2, and then, start the motor two in the positive direction, and its output shaft drives the transverse lead screw 16 to rotate, so that it can move the scraper 19 horizontally. During the movement, when it contacts the bottom end surface of the sedimentation barrel 2, it will scrape off the impurities remaining on the pressing sheet 12 and scrape them into the slag car. After scraping, start the motor two in the reverse direction to bring the scraper 19 back to its original position, and then start the motor one in the reverse direction to bring the pressing sheet 12 out of the sedimentation barrel 2, and then start the rodless cylinder 9 to bring the pressing sheet 12 back to its original position.

[0029] Afterwards, the motor 3 is started in reverse direction to reverse the bottom sealing plate 3 by 90°, and the bottom of the sedimentation barrel 2 is sealed again, and the sedimentation and impurity removal work can be continued.

[0030] Compared with the related art, the zinc oxide powder precipitation and impurity removal device provided by the utility model has the following beneficial effects:

[0031] The utility model provides a zinc oxide powder precipitation and impurity removal device. By setting a pressing sheet 12 that can be lowered, the attachments on the barrel wall of a precipitation barrel 2 can be scraped off at one time, thereby improving the cleaning efficiency. Moreover, by a scraper 19 that moves horizontally, the residues on the pressing sheet 12 can be scraped off. The entire scraping work is relatively thorough, that is, it will not affect the next precipitation and impurity removal work, and manual cleaning is not required, and the convenience performance is good.
