Professional analysis on the working principle of diaphragm filter press products
Speaking of diaphragm filter press products, I wonder how much you know about them? Now our professional staff will introduce to you the working principle of diaphragm filter press products. Let's take a look together, and I believe you will gain something from it.
1. Dewatering: The concentrated sludge continuously moves forward as the screw shaft rotates. Along the direction of the mud cake outlet, the pitch of the screw shaft gradually decreases, and the gap between rings also gradually narrows, resulting in a continuous contraction of the screw chamber volume. Under the action of the back pressure plate at the outlet, the internal pressure gradually increases. With the continuous rotation and pushing of the screw shaft, the water in the sludge is squeezed out, and the solid content of the filter cake continuously increases, ultimately achieving continuous dewatering of the sludge.
2. Self-cleaning of diaphragm filter press: The rotation of the screw shaft drives the continuous rotation of the floating ring. The equipment relies on the movement between the fixed ring and the floating ring to achieve a continuous self-cleaning process, thus cleverly avoiding the common clogging problem of traditional dewatering machines.
3. Concentration with diaphragm filter press: When the screw drive shaft rotates, the multiple solid and flexible laminations arranged around the drive shaft move relative to each other. Under the influence of gravity, water is filtered out from the gaps between the moving laminations, achieving rapid concentration.
