Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb mills, in particular to powder composite modified honeycomb mill equipment. Background Art

[0002] The honeycomb mill is a continuous mechanochemical powder compound modifier, which features three functions: synchronous drying, depolymerization and dispersion, and powder surface chemical treatment. It is specially used for the production of micro-nano powder particles with certain powder size requirements. A high linear speed can generate "eddy currents" to quickly "rub" the material to the original particle size, achieving depolymerization and dispersion of the material; after the process gas is heated, the honeycomb mill is a dryer with good drying capacity during operation; the powder boils in the atomized modifier air, and the high-speed moving powder and the activator produce mechanochemical modification, with good coverage and modification rate.

[0003] For example, the utility model patent with the authorization announcement number CN213254926U discloses a honeycomb mill device, including a base, a shell, a driving mechanism, a feeding mechanism and a grinding mechanism, the shell is mounted on the base; the driving mechanism includes a driving device and a rotating shaft, the driving device is mounted on the base, the rotating shaft is mounted on the output end of the driving device and is placed in the shell; the feeding mechanism includes an air volume chamber and a disintegration structure, the air volume chamber is placed in the shell and located on the base, the shell has a lower feeding port connected to the air volume chamber, the disintegration structure is built into the air volume chamber and installed on the rotating shaft; the grinding mechanism is built into the shell and located on the feeding mechanism, the grinding mechanism is installed on the rotating shaft, the shell is provided with an activator interface and an upper feeding port connected to the grinding mechanism, and the top of the shell is provided with a discharge port. The honeycomb mill device of the above scheme has the advantages of high and uniform activation modification rate.

[0004] The honeycomb mill of the above scheme mainly adopts belt drive, and the motor is arranged at the side end of the honeycomb mill, which occupies a relatively large space, and additional transmission mechanisms such as pulleys and belts are required between the motor and the honeycomb mill. Since the transmission mechanism is at the bottom of the base, there are relatively many parts, and installation, maintenance and replacement of accessories are extremely inconvenient; and the belt transmission efficiency is low, the transmission loss is large, the transmission structure is complex, there is a certain slip rate, and the unstable speed is easy to have an adverse effect on the product quality; in addition, the modified activator directly enters the honeycomb mill through a single inlet, which is not conducive to rapid and uniform mixing with the material.
