[0023] As shown in the attached drawings, the utility model includes a rotating shaft 1, a group of scraper brackets 2 and a group of scrapers 3.

[0024] The scraper bracket 2 includes a bushing 4 and a group of support rods 5. The group of support rods 5 are annularly and evenly installed on the outer wall of the bushing 4. The bushings 4 of the group of scraper brackets 2 are sequentially installed on the rotating shaft 1. Scraper mounting seats 6 are arranged on the support rods 5 of the group of scraper brackets 2 at the same horizontal plane. The group of scrapers 3 are installed in the corresponding scraper mounting seats 6.

[0025] Reinforcing ribs 7 are arranged between two adjacent support rods 5. The overall strength of the scraper device is higher and the service life is longer through the reinforcing ribs.

[0026] The reinforcing rib 7 is an isosceles right triangle. The hypotenuse of the reinforcing rib 7 is arc-shaped. An arc-shaped relief groove 8 is opened at the junction of the two right-angled sides of the reinforcing rib 7. The arc-shaped hypotenuse of the reinforcing rib 7 makes the volume of the reinforcing rib smaller and the weight lighter. A gap is formed between the arc-shaped relief groove 8 and the bushing 4, making it easier to install the bushing locking screw.

[0027] Fixing plates are respectively arranged on the two right-angled sides of the reinforcing rib 7. The fixing plates are detachably installed on the support rod 5 through bolts. The reinforcing rib is detachably installed, which is convenient for replacement.

[0028] The cross-section of the scraper mounting seat 6 is U-shaped. A group of bolt through holes are opened on the scraper mounting seat 6. The scraper 3 is detachably installed in the scraper mounting seat 6 through bolts. The scraper 3 is detachably installed, which is convenient for replacement.

[0029] The scraper 3 is an arc-shaped scraper. Compared with a straight plate scraper, the arc-shaped scraper is easier to scrape out the foam.

[0030] Adjusting bearing seats 9 are respectively arranged at both ends of the rotating shaft 1. The rotating shaft 1 is installed on the side wall of the flotation cell through the adjusting bearing seats 9.

[0031] The number of the group of support rods 5 is four.

[0032] A keyway is opened in the bushing 4, and a threaded positioning hole is opened on the outer wall of the bushing 4. A group of positioning keys are arranged on the rotating shaft 1. The bushing 4 is sleeved on the rotating shaft 1, the positioning key is located in the keyway, and the locking screw is screwed into the threaded positioning hole to fix the bushing 4 on the rotating shaft 1.

[0033] Example 1: The adjusting bearing block 9 is installed on the side wall of the flotation cell by bolts. The two ends of the rotating shaft 1 are respectively installed in the adjusting bearing block 9. According to the need, the lead screw of the adjusting bearing block 9 is rotated to adjust the height of the rotating shaft 1, so that the scraping foam depth can be adjusted.

[0034] When scraping foam, the motor drives the adjusting rotating shaft 1 to rotate, and the foam on the top layer of the flotation cell is continuously scraped out into the foam collection tank through the scraper 3.
