AI Technical Summary

Technical Problem

In the existing technology, multiple vacuum filters are connected to the vacuum bottle in a linear distribution. This results in the vacuum filters closer to the vacuum bottle receiving a stronger negative pressure, while the vacuum filters farther away from the vacuum bottle receive a weaker negative pressure, leading to inconsistent filtration results.

Method used

Design a multi-unit vacuum filtration device, including a disc body, a vacuum bottle, a first threaded tube, an outlet tube, a suction assembly, and multiple sets of vacuum filtration assemblies. The vacuum bottle is connected to the vacuum filter and the cavity through the connecting assembly. The suction assembly generates negative pressure, which causes the liquid in the solid-liquid mixture to pass through the filter membrane of the vacuum filter and flow into the vacuum bottle, thus achieving a uniform negative pressure distribution.

Benefits of technology

This solved the problem of inconsistent filtration results, ensuring that the negative pressure received by each filter is uniform and consistent, thus improving the consistency of filtration results.
