AI Technical Summary
In the existing bamboo pulp bleaching process, when the solution is poured into a pool filled with bamboo products, the contact with the bamboo pulp is not uniform enough, resulting in low reaction efficiency.
A bamboo pulp bleaching device is designed to guide the fused solution into the inside of the water tank through a water pump, and drive the second rotation shaft to rotate through the first motor, so that the solution can be thrown out through the liquid outlet hole of the diverter rod, achieving uniform contact between the solution and the bamboo pulp.
Through this equipment, the contact between the solution and the bamboo slurry is more uniform, which improves the efficiency of the bleaching reaction and avoids the process of the solution being poured into the sink.
