Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a centrifuge cover structure with sealed segmented collection. Background Art

[0002] Existing pusher centrifuges generally collect filtrate in a single outlet, and part of the filtrate at the separation point is treated as wastewater, and the other part re-enters the circulation separation system. Some customers need the filtrate as an economic product (they are more sensitive to the solid content in the filtrate); due to the separation limitations of the structural principle of the pusher centrifuge, 80% of the filtrate is filtered out in the first drum separation section (or the separation section that forms an effective filter cake), and 15% of the filtrate is gradually filtered out in the normal direction corresponding to the movement direction of the filter cake of the pusher centrifuge. The last 5% of the filtrate is attached to the surface of the solid particles due to surface tension. The ratio of filtrate discharged is For example, as the push centrifuge moves in the direction of motion, the corresponding normal phase gradually decreases; generally, the particles of the suspension to be separated entering the centrifuge are in a normal distribution state, and the setting of the screen will intercept most of the particles, so it is inevitable that a small part of the material will be carried in the filtrate; however, firstly, compared with some materials with higher economic value, if the separated filtrate is treated as wastewater, it will inevitably cause corresponding economic losses. Secondly, all the filtrate re-enters the circulation separation system, which correspondingly increases a lot of energy consumption and additional production costs. Thirdly, for users who require the filtrate as an economic product, the fluctuation of the solid content in the filtrate has a greater impact on the quality of their filtrate products. For this reason, a centrifuge cover structure with a sealed segmented collection that can collect the filtrate in segments is proposed. Summary of the invention
