The invention relates to a pressure suction type solid-liquid separator, which comprises a filter, a pressurizing machine is arranged above the rear portion of a filter rack, the pressurizing machine is provided with a pressurizing machine adhesive tape arranged between a pressurizing machine driving roller and a pressurizing machine driven roller, pressurizing machine filter cloth is wound on the periphery of the pressurizing machine adhesive tape, and a pressurizing device is arranged in a gap between the upper part and the lower part of the pressurizing machine adhesive tape. The pressurizing device is provided with a plurality of compression roller sets capable of moving up and down, each compression roller set is provided with a plurality of compression rollers perpendicular to the length direction of a pressurizing machine adhesive tape in parallel, a compression roller set pressing device is further arranged, each compression roller set is connected with the compression roller set pressing device, and a plurality of supporting carrier rollers are arranged at the positions, corresponding to the compression roller sets, below the filter adhesive tape upper part. According to the invention, negative pressure water absorption and pressurized water squeezing are organically integrated on one device, so that the problem of high water content of the product is ingeniously solved, the problem of discontinuous production is solved, and the problem of unsafety caused by high pressure is also eliminated.
Description
technical field [0001] The invention relates to a device for dehydrating slurry to realize solid-liquid separation, especially a kind of dehydration device that can continuously absorb water under negative pressure and squeeze water under positive pressure during uninterrupted transportation. Suction solid-liquid separator. Background technique [0002] At present, there are mainly four known dehydration methods for slurry. One is to pressurize the chamber formed between the filter plates by pumping the slurry or further apply high pressure to the diaphragm filter plate to achieve dehydration; the other is to achieve dehydration by negative pressure water absorption. The third is to squeeze and dehydrate the filter belt on the drum, and the fourth is to loosen the material by vibration and then dehydrate by gravity. The main types of commonly used slurry solid-liquid separation equipment include frame filter press, diaphragm filter press, high pressure filter press, belt fi...
