The composition principle and overall advantages of the screw stacking machine!

The screw stacker should be cleared of debris before starting the machine. In fact, there should be no debris after the equipment is used up, especially in the screw shaft head, equipment slot, filter body, etc., and regular inspections should be done. , Metal, this is even more not allowed; check after turning on the machine, carefully observe whether the screw shaft rotates normally, whether the mixing tank mud is stable, whether the rotating parts are operating normally, and whether there are abnormal noises; the screw stacker must be set during operation Reasonable operation and shutdown time, neither too long nor too short, and complete the entire process as required. The screw stacker machine works for about 6-8 minutes, and the outlet pipe has no water flowing out, and the power supply can be blocked; screw stacker When shutting down, first turn off the sludge feed pump, stop the sludge feeding, turn off the dosing pump, dosing system, stop dosing, empty the flocculation mixing tank, stop the flocculation stirring motor, wait until all the sludge is exhausted, and spray it manually. Drain the filter body for 5 minutes to rinse the equipment clean, and then turn off the power.


Screw stacking machine


The composition and principle of screw stacking machine:


The equipment is mainly composed of frame, screw shaft, moving ring, static ring, spacer ring, stud bolt, flocculation mixer, electric control box, etc.


Features of stacked screw sludge dewatering machine


The screw shaft, the concentration section and the dehydration section are integrated, and the drive part is directly connected with a reducer, and the reducer uses a frequency conversion motor.


The spiral shaft, the concentration section and the dehydration section are integrated, with a compact structure and a small footprint


Concentration: When the spiral propulsion shaft rolls, the multiple solid and active laminations arranged on the periphery of the propulsion shaft move relatively. Under the effect of gravity, water is filtered out of the relatively moving laminations to complete rapid concentration.


The space between the screw shaft, the fixed ring and the moving ring gradually becomes smaller to form a dehydration section: the concentrated sludge moves forward with the rolling of the screw shaft; along the direction of the mud cake outlet, the pitch of the screw shaft gradually decreases, and the ring and the ring The space between the spaces has also gradually decreased, and the volume of the spiral cavity has been continuously shortened; under the effect of the back pressure plate at the outlet, the internal pressure has gradually increased. With the continuous work of the screw propulsion shaft, the water in the sludge is squeezed and discharged. The solid content of the filter cake continues to rise, and the successive dehydration of the sludge is finally completed.


The advantages of the screw stacking machine are easy installation and strong modification. It can basically change the entrance direction according to the construction environment. Its simple operation and design flexibility are deeply trusted by users. However, some users find that the screw stacker occasionally has a slow flow rate after using it for a period of time, which reduces the operating efficiency of the screw stacker to a certain extent.


The main reasons for the slower flow rate:


The machine or accessories are aging. Reasons that may include: connecting pipes, filters, wires and cables, motor aging, screw shaft failure, voltage instability, etc.


If you encounter this kind of problem, please contact the after-sales service of the machine in time to ensure that the problem is solved safely.
