Shangshui Smart

Application award: Annual Innovation Technology Award (Equipment)

Declaration technology: circulating high -efficiency pulp technology

Shangshui Intelligent Circular pulp technology is an efficient powder mixed slurry technology. Its working principle is to first remove part of the gas under vacuum conditions and spread it into a state of diffuse. In the liquid, the decentralized liquid is cut with high -intensity to obtain a dispersed high -quality slurry through the dispersed module composed of the impeller and baffle.

At present, the slurry of power batteries is generally used in traditional dual -planet mixing processes. For the technical difficulties with long and high energy consumption of traditional mixing equipment, the new type of pulp and technology developed by Shangshui Intelligent has greatly shortened the pulp making time and reduced energy consumption. The specific description is as follows:

1. The powder is in a diffuse state to contact the liquid that is quickly flowing in a large area. The wetting time is short and the energy consumption is low.

2. The dispersing module adopts a unique fixed rotor design, using higher line speed and smaller gaps to obtain higher shear strength.

3. Circular slurry technology makes the pulp circular up and forth between the decentralized modules and the circulating tank, which effectively ensures that all pulps are “inevitable decentralized” in the decentralized module, ensuring that the stay time of different parts of the slurry is the same. Ensuring the uniformity and consistency of the dispersing of the slurry, it also greatly shortens the total slurry time.

This technology breaks through the capacity bottleneck of traditional mixing equipment. The capacity of single equipment, small size, high efficiency, and low unit energy consumption can greatly reduce the energy consumption of the slurry system, improve the consistency of the pulp and the stability of batch stability , Reduce customer investment costs and labor costs, and help improve the level of automation and intelligence of the slurry system. At present, the technology has declared four invention patents.
