Causes of sludge running in the snail sludge dewatering machine

- Nov 07, 2020-

The development of everything requires continuous trials. As a new type of sludge dewatering equipment, the stacking screw sludge dewatering machine is of course the same. Only with as much project experience as possible can the equipment continue to improve and improve. Here are some reasons for the mud running of the screw stacker at the application site:

The operation of snail stacking equipment is inseparable from the flocculation of sludge, so the selection of the appropriate flocculating agent is also very important for the treatment effect, so the choice of the agent is very important. The screw stacking thickener first turns on the dosing device to prepare the medicine, and then turns on the sludge pump, the dosing pump, and the screw stacking equipment. In this way, the sludge and chemicals can enter the screw stacking equipment for full flocculation, and then enter the dehydration part for dehydration! In addition to the choice of medicament, the amount of medicament added is also very important. Adding too much medicament will cause the sludge to be sticky and not easy to fall off and the mixed water cannot be squeezed out. Too little medicament addition will affect the effect of flocculation. Phenomena such as mud running or no mud.

Of course, the equipment itself will also have an impact. For example, the gap between the moving and static ring pieces of the equipment is too large, the gap between the back pressure plate of the mud outlet is too small, and some manufacturers, in order to save costs, the ring piece technology does not meet the standard resulting in insufficient flatness, and the material is not 304 stainless steel There will be mud running phenomenon. The condensed sludge of the stacked screw sludge dehydrator moves forward with the rotation of the screw shaft; along the direction of the mud cake outlet, the screw pitch of the screw shaft gradually decreases, and the gap between the rings gradually decreases. The volume of the cavity keeps shrinking; under the action of the back pressure plate at the outlet, the internal pressure gradually increases. Under the continuous operation of the screw drive shaft, the water in the sludge is squeezed and discharged, and the solid content of the filter cake continues to increase. Realize continuous dewatering of sludge. Therefore, the normal operation of the equipment is also inseparable from the debugging experience of the experienced manufacturer of the project.
