Description

Technical Field

[0001] The utility model belongs to the field of stirred reactors, and in particular relates to a transverse stirred reactor. Background Art

[0002] Water-based silicon steel insulating coating can improve the processing performance of silicon steel plates and become an important and indispensable material in the current silicon steel production.

[0003] During the production of water-based silicon steel insulating coating, it is necessary to add corresponding powdered materials such as salt into the reactor. In current technology, the method of increasing the stirring rate of stirred reactors is mainly to increase the stirring shaft speed and larger stirring blades. Some stirred reactors may use multiple stirring shafts to increase the stirring rate and stirring efficiency.

[0004] A transmission method for a stirred reactor with multiple stirring shafts is that the motor output shaft drives the driving gear and the main stirring shaft to rotate, multiple driven gears are meshed with the driving gear, and the slave stirring shaft is coaxially fixedly connected with the corresponding driven gear. This method can make the main stirring shaft and the slave stirring shaft rotate at the same time, and the rotation directions of the two are opposite, which can effectively improve the stirring efficiency of the stirred reactor. However, as the rotation speed of the slave stirring shaft increases, there is a reverse force of the liquid in the reactor on the slave stirring shaft, which causes the slave stirring shaft to be easily deformed when in working state, and then may form a force on the driven gear, causing the meshing of the driven gear and the driving gear to be offset, and further, the teeth in the transmission between the driving gear and the driven gear are damaged or broken.
