AI Technical Summary
In the solid-liquid separation process of existing plate and frame filter presses, some mud cake tends to adhere to the inner wall of the feed hopper and is difficult to slide down into the collection box, resulting in poor mud cake collection effect.
An environmentally friendly, lime-free plate and frame filter press was designed. The drive motor drives the drive shaft and the movable shaft to drive the cam. After the cam contacts the guide hopper, it lifts the guide hopper. Through the cooperation of spring and telescopic rod, the guide hopper vibrates up and down to ensure that the mud cake slides smoothly into the collection box.
It effectively reduces the residue of mud cake on the inner wall of the feed hopper, improves the mud cake feeding efficiency, prevents blockage, and enhances the mud cake collection effect.
