What are the types of spiral sludge dehydrators and how to maintain them?

The types of spiral sludge dehydrators include plate and frame sludge dehydrators, belt sludge dehydrators and centrifugal sludge dehydrators; The maintenance method is to check the equipment regularly. After the quality of oil changes, it should be replaced in time. Next, let's introduce the details.

1、 Types of spiral sludge Dehydrators

1. Plate and frame sludge dehydrator equipment

In the closed state, the sludge pumped by the high-pressure pump is squeezed by the plate and frame, so that the water in the sludge is discharged through the filter cloth, so as to achieve the purpose of dehydration.

2. Belt sludge dehydrator

The sludge layer is entrained by the upper and lower tensioned filter belts and passes through a series of regularly arranged roller cylinders in an S-shape. The pressing and shear force of the sludge layer is formed by the tension of the filter belt itself to squeeze out the capillary water in the sludge layer, so as to realize sludge dewatering.

3. Centrifugal sludge dehydrator

It is composed of a transfer and a screw conveyor with a hollow rotating shaft. The sludge is sent to the drum by the hollow rotating shaft, and is immediately thrown into the drum cavity under the centrifugal force generated by high-speed rotation. Due to different specific gravity, solid-liquid separation is formed. Driven by the screw conveyor, the sludge is transported to the cone end of the drum and continuously discharged from the outlet.

2、 Maintenance of spiral sludge dehydrator

1. During the maintenance process of the screw stack sludge dehydrator, relevant maintenance record sheets shall be determined to form good use habits, especially the contents of regular inspection and relevant treatment results, and various maintenance and detection matters and relevant contents shall be recorded.

2. The bearing of the screw stack sludge dehydrator shall be lubricated frequently during use. According to the service cycle and operation time, it is determined to use the oil gun to inject butter to lubricate the bearing, so as to ensure the service life of the equipment bearing in the sewage treatment process.

3. The lubricating oil of the air compressor must be checked regularly during the daily maintenance of the screw stack sludge dehydrator. The lubricating oil should be added and replaced accordingly. After the quality of the oil changes, it should be replaced in time. At the same time, the and fire relief valve of the air barrel should be opened frequently to remove relevant waste water.

4. The screw stack sludge dehydrator generally uses 32# circulating oil during use. The three-point combination should be checked regularly to determine the internal moisture of the equipment, remove relevant lubricating oil regularly, and supplement it in time to ensure the operation of equipment parts during operation and avoid wear of parts during operation.

5. The spiral sludge dehydrator shall be placed on the machine as far as possible to avoid steam, so as not to affect the service life of the machine. At the same time, the machine shall not be placed outdoors.

The above is an introduction to "what are the types of stacked screw sludge dehydrators and how to maintain them". I hope it can help you.
