[0015] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0016] like Figures 1 to 4As shown, a blast furnace dust removal ash carbon-iron-zinc separation device includes a frame 1. Two conduits 13 are fixedly installed on the inner wall of the frame 1. A collection cylinder 15 is movably installed between the two conduits 13. Multiple electromagnetic plates 18 are connected between the two conduits 13 inside the collection cylinder 15. An iron outlet 19 is inserted through the lower part of one side of the collection cylinder 15, and a zinc outlet 20 is inserted through the middle of the collection cylinder 15. A fluidizing box 6 is fixedly connected to the upper end of the collection cylinder 15. A scraper 22 is movably installed inside the fluidizing box 6 and slides against the upper wall of the fluidizing box 6. A positive electrode plate 23 is provided on the inner wall of the fluidizing box 6. Several coils 17 are provided on the inner wall of the collection cylinder 15. An inlet plate 14 is installed on one side of the collection cylinder 15, and a carbon outlet 16 is inserted through the one side of the fluidizing box 6.

[0017] In Example 1, the dust to be treated is fed into the collection cylinder 15 through the feed port at the top of one side of the fluidized bed fluidizing box 6. The external pipe is connected to the inlet plate 14 to send in fluidizing gas. After the dust enters, it mixes with the fluidizing gas. According to the different densities of carbon, iron and zinc in the dust, carbon particles float to the surface of the fluidized bed 6, iron particles sink to the bottom of the collection cylinder 15, and zinc is distributed in the middle between the fluidized bed 6 and the collection cylinder 15. The carbon particles are adsorbed onto the positive electrode plate 23 by the electric field. The collected material is discharged to the carbon outlet 16. The sinking iron particles are adsorbed by the collection cylinder 15 and discharged from the side iron outlet 19. Then the zinc gas is discharged from the zinc outlet 20. This effectively separates the mixed particles of carbon and iron, avoids high iron content after mixed flotation, and improves the separation effect of ultrafine carbon and iron particles.

[0018] like Figure 1 - Figure 3 As shown, a through plate 4 is fixedly connected to the inner side of the frame 1, and a traction slider 11 is slidably installed on the inner side of the through plate 4. A magnetic chuck 12 is fixedly connected to the bottom end of the traction slider 11.

[0019] In Example 2, the traction slider 11 slides in the through plate 4, thereby driving the magnetic chuck 12 to move and then driving the scraper 22 to scrape the carbon material on the positive electrode plate 23.

[0020] like Figure 1 - Figure 3 As shown, two grooves 9 are opened on the upper wall of the chute 9. The scraper 22 is slidably set with the chute 9. The magnetic chuck 12 is used in conjunction with the scraper 22. The servo motor 2 is installed on the inner side of the frame 1. The threaded rod 3 is installed horizontally on the inner side of the frame 1. The threaded rod 3 is connected to the output shaft of the servo motor 2. The threaded sleeve 5 is threaded on the outer surface of the threaded rod 3. The threaded sleeve 5 is fixedly connected to the traction slider 11. The telescopic bolt 8 is inserted on one side of the magnetic chuck 12. The telescopic bolt 8 abuts against the through plate 4. The outer surface of the telescopic bolt 8 is fitted with a spring 10.

[0021] In Example 3, after the servo motor 2 is turned, the output end drives the threaded rod 3 to rotate, so that the threaded sleeve block 5 moves horizontally along the thread groove. When the magnetic chuck 12 moves, it drives the telescopic bolt 8 to abut against the through plate 4 and compress the spring 10, resulting in good circulation.

[0022] Working principle: Dust particles are fed into the collection cylinder 15 through the feed inlet at the top of one side of the fluidized bed fluidizing box 6. An external pipe connects to the inlet plate 14 to supply fluidizing gas. The dust particles mix with the gas. Based on the different densities of carbon, iron, and zinc in the dust particles, carbon particles rise to the surface of the fluidized bed 6, iron particles sink to the bottom of the collection cylinder 15, and zinc particles are distributed between the fluidized bed 6 and the collection cylinder 15. Carbon particles are adsorbed onto the positive electrode plate 23 by the electric field. The servo motor 2 is activated by an external controller. 2. After operation, the output end drives the threaded rod 3 to rotate, causing the threaded sleeve block 5 to move horizontally along the thread groove, thereby driving the traction slider 11 to slide in the through plate 4, which in turn drives the magnetic chuck 12 to move and drive the scraper 22 to scrape the carbon material on the positive electrode plate 23. When the magnetic chuck 12 moves, it drives the telescopic bolt 8 to contact the through plate 4 and compress the spring 10 to prevent foreign objects from getting stuck. The collected material is discharged to the carbon outlet 16. The sinking iron particles are adsorbed by the collection cylinder 15 and discharged from the side iron outlet 19. Then the zinc gas is discharged from the zinc outlet 20 and enters the subsequent acid leaching process.

[0023] Working principle: When in use, first rotate the crank handle 674 to move the mounting plate 63 along with the moving top block 62 to compress the spring 65. When there is enough space between the moving top block 62 and the fixed top block 61 to place the filtration bottle 2, stop rotating and place the filtration bottle 2 on the filtration bottle placement platform 31 between the fixed top block 61 and the moving top block 62. Then, rotate the crank handle 674 and the sliding block 673 to move towards the support plate 671. Under the elastic force of the spring 65, the mounting plate 63 also moves towards the fixed top block 61 until the moving top block 62 and the fixed top block 61 clamp the filtration bottle 2. Stop rotating the crank handle 674. Then, the operator holds the connector 7, with the branch pipe 5 and the connector 7 in a normally connected state. Insert the rubber plug 72 of the connector 7 into the connecting pipe of the filtration bottle 2. According to the number of filtration bottles 2 used, open the manual valve 51 on the corresponding branch pipe 5. Finally, start the vacuum pump to perform the filtration action.

[0024] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
