Problems solved by technology

[0003] However, the existing molecular sieve production equipment has problems such as relying on skilled workers, time-consuming and laborious labor, uneven product size, high degree of unreliability, unstable product performance, and high scrap rate caused by untimely detection.
During the current production and preparation of molecular sieves, due to real-time changes in the viscosity of materials, material jams in relatively sticky and dry parts are prone to cause kneader motor failure, which in turn leads to downtime and delays; Moreover, it is also difficult to discharge the material in the production device. Operators need to use tools to transfer the molecular sieve. The production process is extremely unsafe, and accidents such as being involved in the kneader are prone to occur.
The tank with high-viscosity molecular sieve slurry is prone to stubborn scale, which affects the subsequent material ratio and promotes corrosion and aging of equipment. Each batch of production needs to be cleaned manually, which takes up a lot of production time
