The collecting units include a horn cover 15 and a collecting box 16. The collecting box 16 is connected to the housing 10 through the horn cover 15.

The duct 17 is provided with a notch matching the dust collecting groove 23. The dust collecting groove 23 is embedded in the notch. The push-pull block 19 is connected to the dust collecting groove 23. The push-pull block 19 is located on the outside of the duct 17.

The position of the duct 17 corresponding to the first magnet 21 is provided with a second magnet 22, and the first magnet 21 and the second magnet 22 are attracted to each other.

[0015] Preferably, the two blades 5 on the same fixing ring 4 are symmetrical with respect to the metal rod 2 passing through the fixing ring 4 , and the two blades 5 are located on the same vertical straight line.

[0016] The positions of the two blades 5 are set in this way mainly to enable the blades 5 to cut the middle of the carbon black powder block pressed into a ring shape, so that the carbon black powder ring will not adhere to the metal rod 2 and easily fall off directly.

[0017] Preferably, a bracket 25 is provided below the housing 10 .

[0018] Preferably, a control box 26 is provided above the box body 1 , and a PLC is provided in the control box 26 . The PLC is electrically connected to the first motor 7 , the second motor 11 , and the fan 18 .

[0019] A collection method of the carbon black powder collection system as described above comprises the following steps: 1) Cooled gas containing carbon powder is introduced into the box 1 through the air inlet pipe 24; 2) The ions generated by the plasma generator 6 enter the box 1 through the metal rod 2, and the metal rod 2 absorbs the carbon black powder in the gas; 3) The first motor 7 is controlled by the PLC to rotate forward and reverse regularly, thereby driving the fixing ring 4 and the blade 5 to move circularly on the metal rod 2, squeezing and cutting the carbon black powder into blocks to make them fall. At the same time, the gas that is not completely adsorbed is filtered from the duct 17 through the filter cloth 20 of the filter unit and then sucked back into the box 1 by the fan 18; 4) The blocky carbon black powder is pressed into the filter screen 13 by the pressing rod 14, so that the carbon black powder is reduced to powder under the cutting of the filter screen 13 and enters the collection box 16 to achieve recycling.

[0020] Preferably, in step 3), there are three filtering units.

[0021] When the gas mixed with carbon black powder passes through the metal rod 2, the carbon black powder therein will be adsorbed on the metal rod 2, and then the first motor 7 will drive the screw 8 to rotate in a regular cycle, thereby driving the moving block 9 to move back and forth on the screw 8, and then driving the moving block 3 to move along the axial direction of the metal rod 2, driving the fixed ring 4 to move on the metal rod 2, so as to push the carbon black powder on the metal rod 2, and some of the powder will fall directly, pass through the filter 13 and directly enter the collecting box 16 to be collected, and some of the carbon black powder will be pushed to the edge by the fixed ring 4 to form a ring around the metal rod 2, and as the fixed ring 4 moves further, the blade 5 will cut the carbon black powder ring into two semicircular carbon black powder blocks, and the cut carbon black powder blocks will fall onto the filter 13, and the second motor 11 will keep driving the pressure rod 14 to rotate along the upper surface of the filter 13, and The side of the pressure rod 14 close to the upper surface of the filter screen is an inclined surface. As the pressure rod 14 rotates, the carbon black powder block will be forced forward by the pressure rod 14 under the continuous action of the inclined surface. In the process of being pushed, the carbon black powder block will gradually be pushed into the filter screen 13 and pass through the filter screen 13. In fact, the filter screen 13 at this time plays the role of mesh cutting and crushing. As long as the aperture of the filter screen 13 is well controlled, the carbon black powder block passing through the filter screen 13 will be cut into carbon black powder and then enter the collection box 16 to complete collection. The continuous rotation of the pressure rod 14 here presses the carbon black powder block into the filter screen 13, and can also realize the replacement of the old carbon black powder in the filter screen 13 with the new one. Even if the filter screen 13 is blocked, new powder will be pressed in under the action of the pressure rod 14, so the powder previously retained in the filter screen 13 will be pushed out of the filter screen 13, forming better sustainability.

[0022] When the gas passes through the box 1, the particles are adsorbed by the metal rod 2 and enter the conduit 17. Then, after being adsorbed by the filter unit, the gas can return to the box 1 through the action of the fan 18 and be repeatedly adsorbed, thereby improving the adsorption rate. In addition, the adsorption unit is provided with a filter cloth 20, so that the gas passing through the conduit 17 can also be adsorbed once, reducing the number of cycles and improving work efficiency. Here, the installation of the adsorption unit is arranged through a magnetic adsorption structure, so that the adsorption unit can be removed more conveniently, greatly improving the convenience of disassembly and maintenance.

[0023] The travel block 9 here can not only drive the moving block 3 to move under the action of the screw 8, but also effectively scrape off the powder that falls into the thread of the screw 8 to play a cleaning role. The cooperation of the fixing ring 4 and the blade 5 actually plays a role in cleaning the powder on the metal rod 2. In this way, the mechanism inside the box 1 and the shell 2 does not actually require more frequent cleaning, which reduces the number of maintenance times and improves the continuity of system operation.

[0024] Compared with the prior art, the carbon black powder collection system and method first collects most of the carbon black powder by plasma adsorption, and then scrapes and cuts the carbon black powder through the cooperation of the fixed ring 4 and the blade 5, so that it falls onto the filter screen 13, and is then forced to be crushed and pressed down by the pressure rod 14 to achieve block crushing. During this period, cyclic collection can be achieved, and micro-collection is achieved through the filtering unit, which improves the collection efficiency, extends the system maintenance cycle, and improves production efficiency.
