Technical characteristics and working principle of drum thickener

There are many kinds of machines for sewage and sludge treatment in our daily life. Today we are going to talk about a rotary drum thickener, which also has a fast and effective machine for sewage treatment. Let's take a look at its working principle and technical characteristics.





1、 Principle of drum thickener

1. It is a device that uses the natural precipitation of solid particles in slime water to complete the continuous concentration of slime water. The coal slurry that needs to be concentrated first enters into the free settling zone, and the particles in the water sink rapidly by their own weight. When they sink into the compression zone, the coal slurry gathers into close contact flocs and continues to sink into the concentration zone. Due to the operation of the scraper, the concentration zone forms a conical surface, and the concentrate is further compressed and squeezed out of the water by the pressure of the scraper, and finally transferred by the underflow pump To filter press.

2、 Technical features of drum thickener

1. Each drum is driven by a reduction motor (0.37 kW). The frame is made of stainless steel SS 2333.

2. The drum thickener is equipped with a stainless steel cover plate which is easy to remove. The filter cloth is equipped with continuous flushing system, which is composed of stop valve, filter, solenoid valve and water pipe with nozzle.

3. The diameter of the drum thickener is 400 mm, 600 mm, 900 mm or 1400 mm.

4. Considering the size of the hydraulic load, the drum thickener can be installed on the belt filter press.

5. As the flocculated sludge is stably transported from the drum thickener to the belt thickener, no additional flocculant is needed.

6. When the drum drive is installed on the thickener, the belt is integrated into the rotary filter press.

7. In other applications, drum thickener is also suitable for thickener. When the drum thickener is used as a separate thickening system, the thickener is equipped with a separate automatic control cabinet.
