AI Technical Summary

Technical Problem

Traditional filter presses have low filtration efficiency during the feeding stage. The presence of moisture and gas in the material results in insufficient compactness of the filter cake, affecting overall production capacity.

Method used

A vacuum negative pressure auxiliary filtration device, including a mounting bracket, is installed in the feed channel of the filter press. Through the feed assembly and vacuum negative pressure auxiliary mechanism, the feed pump can deliver the filter material into the filter chamber through the feed pipeline assembly. In conjunction with the vacuum chamber in the movable press base, the vacuum pump generates a negative pressure environment when it is working, which removes moisture and gas from the material. The filtration speed is accelerated by the positive pressure feeding and negative pressure extraction.

Benefits of technology

This accelerates the filtration speed of the material in the filter chamber, allowing the material to initially form a relatively compact filter cake, laying a good foundation for the subsequent pressure filtration process.
