What are the process characteristics and technical parameters of sludge thickener?

The residence time of the sludge thickener is short, the static pressure head of the feed part is added, the dehydration efficiency is improved, the operation is flexible, and the maintenance is simple and convenient. The "process characteristics and technical parameters of the sludge thickener" are introduced in detail below.

1、 Process characteristics of sludge thickener

1. The residence time of sludge thickening is short. The residence time of traditional sludge thickening tank is generally more than 10 hours, while the dehydration residence time of belt thickening section is only tens of seconds to 1-2 minutes on average.

2. The belt concentration section is designed as an inclined type, which increases the static pressure head of the feed part and improves the dehydration efficiency.

3. Stepless speed regulation is adopted in the concentration section and pressure filtration section for better process matching.

4. Filter cloth deviation correction device: the sludge thickener adopts pneumatic feedback single side automatic deviation correction.

5. Filter cloth cleaning device: the sludge thickener adopts rate nozzle and washing mechanism for automatic cleaning.

6. Filter cloth tensioning device: the sludge thickener adopts pneumatic tensioning, so the operation is flexible and the maintenance is simple and convenient.

2、 Main technical parameters of sludge thickener

1. Upper limit particle settling velocity in overflow: the process of ore particle settling in concentration tank is very complex, and there is no accurate calculation method at present. The factors affecting the settling velocity of ore particles are density, particle size, shape and surface properties of ore particles.

2. Sludge thickener area: in the actual work of design and production, the thickener area required for thickening operation is generally calculated by the sedimentation rate of upper limit particles in overflow.

3. Treatment capacity per unit area of sludge thickener: the treatment capacity per unit area of sludge thickener is generally selected according to industrial or simulation tests. If there is no test data, it can be selected with reference to the actual production index of similar concentrators.

4. Depth of sludge thickener: the depth of the thickener depends on the height of each area through which the slurry passes during the thickening process. It is necessary to add the height of the clarification area, the height of the free settlement area, the height of the compression area and the height of the scraper movement area of the thickener to obtain its depth.
