Description

Technical Field

[0001] The utility model relates to the technical field of carbon black processing, in particular to a dust collecting and recycling device for a carbon black pellet mill. Background Art

[0002] Carbon black is a type of amorphous carbon with a very large surface area. It is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances under insufficient air conditions. It can be used as a black dye to make Chinese ink, printing ink, paint, etc. It is also used as a reinforcing agent for rubber. Existing carbon black grinding devices generally add the carbon black to be ground into a grinding container first, remove the ground carbon black from the grinding container after the carbon black in the grinding container is ground, and then add the carbon black to be ground to continue grinding. This process is discontinuous, not only cumbersome to operate, but also low in carbon black grinding efficiency.

[0003] The existing disclosed technology, with publication number CN210752859U, discloses a carbon black grinding and processing device, comprising a mounting table, a plurality of support legs evenly mounted on the bottom wall of the mounting table, a grinding groove formed on the top wall of the mounting table, the bottom end of which extends to the bottom side of the mounting table, a grinding block rotatably mounted in the grinding groove and cooperating with the grinding groove, the top end of the grinding block being connected to a driving device, a material guide plate mounted on one side of the top of the mounting table, the material guide plate being tilted, the bottom end of which extends into the grinding groove, a discharge plate fixedly mounted on the bottom wall of the mounting table, the discharge plate being tilted, and the discharge plate being located on the bottom side of the grinding groove. In the utility model, the carbon black to be ground is added into the grinding groove from the top of the mounting table, and the ground carbon black falls directly from the mounting table and the bottom end of the grinding groove. This is not only convenient to operate, but also allows for a continuous processing process, greatly improving the grinding efficiency of the carbon black and having a reasonable design.

[0004] Although the above patent can gradually grind carbon black into smaller pieces, has good grinding effect, and improves the grinding quality of carbon black, there are still some shortcomings in its use. First, the grinding block used in the patent is a fixed structure, which can only grind out carbon black of a fixed diameter, and the applicability of the device is not high enough. Secondly, carbon black dust will overflow during the grinding process, which not only causes waste of carbon black raw materials, but also causes certain pollution to the environment. In addition, the patent lacks a structure for pre-crushing carbon black. If the carbon black is directly ground, the grinding efficiency will not be high enough. For the problems in the relevant technology, no effective solution has been proposed yet. Utility Model Content
