[0027] Further, the top of the inlet box 21 is fixedly connected with an inlet pipeline 211, and the bottom of the inlet box 21 is provided with a discharge port 212.

[0028] Further, the spacing part 22 comprises a first motor 221 and a semicircular block 222, the first motor 221 is fixedly installed at the top of the inlet box 21, the semicircular block 222 is fixedly connected to the output end of the first motor 221 and is fixedly installed inside the inlet box 21.

[0029] In this embodiment, the inlet pipeline 211 is connected to the carbon black after densification, so as to avoid excessive addition of carbon black at one time; after a part of the carbon black enters the inside of the inlet box 21, the first motor 221 is driven to rotate the semicircular block 222, since the semicircular block 222 is in the shape of a fan, the semicircular block 222 will block the inlet pipeline 211, so as to block excessive addition of carbon black; the carbon black in the inlet box 21 is discharged into the inside of the screening tank 1 through the discharge port 212 along with the rotation of the semicircular block 222; in the inside of the screening tank 1, a part of the magnetic impurities in the carbon black after densification are adsorbed, and the remaining carbon black normally passes through the high-precision magnetic screen 12.

[0030] Embodiment Two

[0031] As shown in Figure 1 , Figure 2 and Figure 4 , the inside of the screening tank 1 is provided with a separation assembly 3 for screening carbon black, and the side end of the screening tank 1 is provided with a brine assembly 4 for storing high-concentration brine.

[0032] Specific, separation assembly 3 includes separation tank 31, fixed shell 32, drive components 33, separation tank 31 is fixedly connected in the inside of screening tank 1, fixed shell 32 is fixedly connected in the side end of separation tank 31, drive components 33 are fixedly installed in the inside of fixed shell 32, salt water assembly 4 includes salt water tank 41, first water pipe 42, second water pipe 43, first water pipe 42 one end is fixedly connected in the side end of salt water tank 41, and the other end is fixedly connected in the inside of screening tank 1, second water pipe 43 one end is fixedly connected in the side end of salt water tank 41, and the other end is fixedly connected in the inside of screening tank 1.

[0033] Further, drive components 33 include second motor 331, threaded rod 332, moving block 333, blocking block 334, second motor 331 is fixedly installed in the side end of fixed shell 32, threaded rod 332 one end is fixedly connected in the output end of second motor 331, and the other end is fixedly installed in the inside of fixed shell 32, moving block 333 is screw-connected on the surface of threaded rod 332, blocking block 334 is fixedly connected in the side end of moving block 333, and is fixedly installed in the inside of separation tank 31.

[0034] In the embodiment, the concentration of high-concentration salt water is configured according to the required density of carbon black, and the high-concentration salt water solution is added to the inside of the screening tank 1 through the salt water tank 41, and the liquid surface is always in the separation tank 31. Since the descending speeds of carbon black with different densities in the high-concentration salt water solution are different, the carbon black after passing through the high-precision magnetic screen 12 will enter the high-concentration salt water in the inside of the screening tank 1 and start to sink. However, due to the difference in density, the carbon black with qualified density will normally descend, but the unqualified carbon black will slowly sink. After the carbon black enters the high-concentration salt water for a certain period of time, the second motor 331 is driven to rotate the threaded rod 332, so that the moving block 333 moves on the surface of the threaded rod 332, thereby making the blocking block 334 isolate the screening tank 1 and block the unqualified carbon black.

[0035] The working process of the utility model is as follows:

[0036] When the carbon black is discharged, the inlet pipe 211 is connected to the carbon black after densification to avoid excessive addition of carbon black at one time. After part of the carbon black enters the inside of the inlet tank 21, the first motor 221 is driven to rotate the semicircular block 222. Since the semicircular block 222 is in the form of a fan, the semicircular block 222 will block the inlet pipe 211, thereby preventing excessive addition of carbon black. The carbon black entering the inside of the inlet tank 21 is discharged from the discharge port 212 into the screening tank 1. In the screening tank 1, part of the magnetic impurities in the carbon black after densification are adsorbed, and the remaining carbon black normally passes through the high-precision magnetic screen 12. The concentration of the high-concentration brine is configured according to the required density of the carbon black. The high-concentration brine solution is added to the inside of the screening tank 1 through the brine tank 41, and the liquid surface is always separated from the separation tank 31. Since the descending speed of carbon black of different densities in the high-concentration brine solution is different, the carbon black after passing through the high-precision magnetic screen 12 will start to sink in the high-concentration brine in the inside of the screening tank 1. However, due to the difference in density, the carbon black of qualified density will normally descend, but the unqualified carbon black will slowly sink. After the carbon black enters the high-concentration brine for a certain period of time, the second motor 331 is driven to rotate the threaded rod 332, so that the moving block 333 moves on the surface of the threaded rod 332, thereby making the blocking block 334 isolate the screening tank 1 to block the unqualified carbon black. The qualified carbon black sinks to the isolation net 13 and is blocked by the isolation net 13. Then, the high-concentration brine in the inside of the screening tank 1 is pumped out through the first water pump 42, and the qualified carbon black is taken out through the material taking port 11. After the qualified carbon black is taken out, the blocking block 334 is retracted and then the unqualified carbon black is taken out.
