Battery gradelithium carbonateIt is a key intermediate in the production process of lithium batteries, used to manufacture positive electrode materials or electrolyte additives for batteries. In order to improve the reactivity of the material and ensure the normal operation of subsequent processes, lithium carbonate powder needs to be dehydrated and ensure the purity of the material before further processing.

A lithium salt production enterprise uses a disc dryer to dry lithium carbonate. The disc dryer uniformly heats the lithium carbonate powder laid on the drying disc through heating and stirring, thereby reducing its moisture content. In order to ensure stable operation of the equipment, there is also a transfer warehouse at the inlet and outlet of the disc dryer.

1 Measurement difficulties of transfer warehouse in disc dryer

The company has installed a level switch in the transfer warehouse of the disc dryer to detect lithium carbonate powder and provide high-level alarms to avoid material overflow. However, the measurements of these level switches are not reliable and often result in false alarms, causing the company to be frequently disturbed by instrument failures during the production process. This not only increases the workload of maintenance personnel, but also invisibly increases production costs.

Installation site: Small space, strong dust, strong adhesion

The company attempted to find a new solution, but found that it needed toMeet the on-site installation conditionsandStable and reliable measurementThe instrument is not easy. The space above the transfer warehouse is narrow, requiring instruments to be compact enough, otherwise it is difficult to install. At the same time, the strong dust and adhesion inside the silo have put forward strict requirements for the anti-interference ability and reliability of the instrument.

At this moment, the measurement solution brought by VEGA measurement engineers has solved the urgent problem for users.

2 VEGA's flexible solutions

After carefully understanding the customer's needs, VEGA's measurement engineers decided to adoptSplit type level switchTo measure lithium carbonate powder. This level switch can be used for the vast majority of media,Not affected by dust adhesionThe measurement is stable and reliable, the mechanical structure is sturdy and has a long service life, significantly reducing the maintenance workload of users.

At the same time, in order to adapt to the installation conditions on site, VEGA engineers have configured a split type header for users. Through a 5-meter-long connecting cable, users can install the meter head to any position, overcoming the problem of installation limitations and facilitating users to observe the instrument status, debug and maintain the instrument in a convenient location.
