Stacked screw type sludge dewatering machine is often used in our daily life. Its appearance has brought great convenience to our life and work. What's its structure principle? Let's give you a brief introduction.

1. Concentration: when the screw pushes the shaft to rotate, the multiple solid and flexible laminations set on the periphery of the pushing shaft move relatively. Under the action of gravity, the water is filtered out from the relative moving lamination gap to realize rapid concentration.

2. Dewatering: the thickened sludge moves forward with the rotation of the spiral shaft; along the outlet direction of the sludge cake, the pitch of the spiral shaft gradually decreases, the gap between the rings also gradually decreases, and the volume of the spiral cavity constantly shrinks; under the action of the back pressure plate at the outlet, the internal pressure gradually increases, and under the continuous operation of the spiral shaft, the water in the sludge is squeezed out The solid content of filter cake increases continuously, and then the continuous dewatering of sludge is realized.

3. Self cleaning: the rotation of the screw shaft drives the traveling ring to rotate continuously. The stacked screw sludge dewatering machine realizes continuous self-cleaning process by moving between the fixed ring and the traveling ring, so as to skillfully avoid the common blockage problem of the traditional dewatering machine.

Power on of the screw type dehydrator: the rotating speed of the wave wheel is not slow after adding water. The clothes in the barrel roll with the rotation of the wave wheel. After washing for a period of time, the clothes are cleaned and working normally. Water leakage inspection: water leakage is a fatal defect of water washing equipment. All the leakage of the screw type sludge dehydrator, can not be selected. During inspection, water the washing bucket and dewatering bucket first to see if there is water leakage under the two buckets. Then place the drain pipe on the ground and close the drain switch. If there is still water flowing out of the drain pipe, it can be judged that the water leakage in the washing bucket. Check the water leakage in the dewatering bucket, only fill the water in the washing bucket, and the water in the water tank is not filled. Open the drain switch to discharge the water in the washing bucket. Check the dewatering bucket, so that there is water overflow in the bucket, indicating that the water leakage in the dewatering bucket. For the screw type dehydrator, we should do well in maintenance and maintenance work in order to make the equipment play a greater role.
