Design advantages
● The concentration section has been changed to an integrated concentration and pressing unit, which greatly saves space and the front-end sludge dewatering equipment. After this stage, the sewage can be dewatered to around 85%.
● The rakes in the concentration section feature a new design that causes the sludge to tumble during operation, allowing more free water to be filtered out through the filter cloth. Refer to the figure below.
The surface of the sludge rake features an arc-shaped design, which more effectively facilitates the tumbling of the sludge.
● The mixing of lime, iron salt, and sludge is carried out using an integrated spiral mixing and crushing device, as shown in the figure below.
As shown in the diagram, this component consists of three truncated double screws primarily responsible for conveying and mixing. The section between the two screw segments contains crushing blades (see right figure), which break down the mixture of sludge and lime, resulting in more thorough blending and reduced agglomeration.
● Lime dosing is carried out using a precision feeder, which controls the feeding screw through a frequency converter. The addition amount is adjusted according to actual conditions to ensure an appropriate mixing ratio and controllable moisture content in the discharged sludge cake.
● The equipment is pre-fitted with an air blow connection, which is positioned behind the cleaning water pipe. After the filter cloth is cleaned, the air blow function removes residual moisture, enhancing the cloth's permeability and resulting in lower moisture content after subsequent pressing.
● The roller arrangement follows a scientific design with progressively increasing pressure. The pressing force intensifies towards the later stages, as illustrated in the diagram below.
