[0025] Specifically, the scraper assembly 9 includes a fixing ring 91, a scraper ring 92, a fixing nut 93, a fixing screw 94 and a through hole 95. The fixing ring 91 is connected to the side wall of the graded magnetic separation mechanism 8. The scraper ring 92 is arranged on one side of the fixing ring 91. The fixing screw 94 is connected to the side of the fixing ring 91 close to the scraper ring 92. The through hole 95 is arranged on the scraper ring 92 at a position corresponding to the fixing screw 94. The fixing nut 93 is connected to the outer wall of the fixing screw 94 and is located on the side of the scraper ring 92 away from the fixing ring 91.

[0026] By adopting the above technical solution, the fixing nut 93 is rotated and removed from the fixing screw 94, so that the external fixing force between the scraper ring 92 and the fixing ring 91 is lost. When the scraper ring 92 is moved, the magnetic mineral impurities adhering to the grading magnetic separation mechanism 8 can be scraped and cleaned during the movement of the scraper ring 92.

[0027] Specifically, the collecting assembly 3 includes a collecting box 31, a supporting rod 32 and a moving port 33. The moving port 33 is provided on the magnetic separation box 2, and the collecting box 31 is inserted into the moving port 33. The supporting rod 32 is connected to the side wall of the screening box 4 and located below the collecting box 31.

[0028] By adopting the above technical solution, the collecting box 31 is moved so as to be overlapped on the supporting rod 32. When it is necessary to scrape and clean the magnetic mineral impurities adhering to the grading magnetic separation mechanism 8, the collecting box 31 is first moved so as to be moved along the moving opening 33 and inserted into the magnetic separation box 2. After the scraping assembly 9 is used to scrape the material, the scraped magnetic mineral impurities fall into the collecting box 31 under the action of gravity for collection.

The movement of the collecting box 31 drives the sealing plate 34 to move and fit onto the side wall of the magnetic separation box 2. Then the grading magnetic separation mechanism 8 is started, and the quartz sand raw material to be magnetically separated is injected into the magnetic separation box 2 through the feed hopper 1. After the magnetic separation operation of the grading magnetic separation mechanism 8 inside the magnetic separation box 2, the magnetic mineral impurities in the quartz sand raw material remain on the grading magnetic separation mechanism 8, and the quartz sand raw material falls into the screening mechanism 6 in the screening box 4 for screening operation. After the magnetic separation and screening operation is completed, the box door 5 on the screening box 4 is first opened, and the quartz sand raw material remaining after screening is taken out from the screening mechanism 6, and then The collecting box 31 is moved so as to be moved along the moving opening 33 and inserted into the magnetic separation box 2, and then the box door 5 on the magnetic separation box 2 is opened, and then the fixing nut 93 is rotated and removed from the fixing screw 94, so that the external fixing force between the scraper ring 92 and the fixing ring 91 is lost. When the scraper ring 92 is moved, the magnetic mineral impurities adhering to the graded magnetic separation mechanism 8 can be scraped and cleaned. The scraped magnetic mineral impurities fall into the collecting box 31 under the action of gravity for collection, which is convenient for the operator to clean and collect the magnetic mineral impurities remaining on the graded magnetic separation mechanism 8, thereby ensuring the subsequent use effect of the graded magnetic separation mechanism 8;

[0038] The structure and principle of the screening mechanism 6 composed of a movable slot, a second discharging hopper, a screen, a spring, a screening trough body, and a vibration motor in the utility model have been disclosed in a graded magnetic separation device for quartz sand disclosed in Chinese patent application No. 202122715194.1. Its working principle is: a screening trough body is arranged on the inner side of the screening box body 4, the top of the screening trough body is arranged with an opening, a screen is fixedly connected through the bottom of the screening trough body, a second discharging hopper connected thereto is fixedly connected to the bottom of the screening trough body, a movable slot hole is penetrated through the bottom of the screening box body 4 for the bottom end of the second discharging hopper to pass through and move, the bottom end of the second discharging hopper passes through the movable slot hole and extends to the bottom of the screening box body 4, and both sides of the screening trough body are It is fixedly connected with a plurality of springs, one ends of which are fixedly connected to the inner wall of the screening box body 4, and a vibration motor is fixedly installed on the front side wall of the screening trough body. When in use, the vibration motor is started, and the quartz sand raw material after magnetic separation falls onto the screen in the screening trough body, and the fallen quartz sand raw material is screened by the screen, and the larger quartz sand particles in the quartz sand raw material are blocked on the screen, and the quartz sand particles smaller than the sieve hole diameter of the screen fall into the second discharging hopper and fall through the second discharging hopper for collection by personnel, so that the size of the quartz sand particles after processing is more uniform, and through the coordinated setting of the springs, the vibration of the vibration motor drives the vibration of the screening trough body and the screen, thereby improving the screening efficiency of the quartz sand raw material on the screen.

[0039] The structure and principle of the grading magnetic separation mechanism 8 composed of a magnetic roller, a rotating shaft, an inclined plate, and a rotating motor in the utility model have been disclosed in a grading magnetic separation device for quartz sand disclosed in Chinese patent application No. 202122715194.1.

A magnetic roller is arranged above the inclined plate, and a rotating shaft is connected to the inside of the magnetic roller. One end of the rotating shaft is connected to a rotating motor.

After the magnetic separation operation of the grading magnetic separation mechanism 8 inside the magnetic separation box 2, the magnetic mineral impurities in the quartz sand raw material remain on the grading magnetic separation mechanism 8, and the quartz sand raw material falls into the screening mechanism 6 in the screening box 4 for screening operation. After the dust generated during the screening process of the screening mechanism 6 enters the adsorption cylinder 71, it enters the adsorption tube 72 through the first adsorption port 75 and the second adsorption port 77, and then enters the dust cylinder in the dust collector 73 through the adsorption tube 72 for collection, so as to avoid the dust from spreading during the screening process. The quartz sand raw materials remaining after screening are taken out from the inside of the screening mechanism 6, and then the collecting box 31 is moved so that it is moved along the moving opening 33 and inserted into the inside of the magnetic separation box 2, and then the box door 5 on the magnetic separation box 2 is opened, and then the fixing nut 93 is rotated and removed from the fixing screw 94, so that the external fixing force between the scraper ring 92 and the fixing ring 91 is lost, and the scraper ring 92 is moved.
