大きな動力費を要する欠点があった。(Problems to be Solved by the Invention) Among the above-mentioned filters, in the former conventional cross-flow filter, when solid particles in the slurry liquid accumulate on the surface of the filtration layer of the cylindrical porous tube, the resistance of the filter medium increases. Since the filtration speed decreases, it is necessary to flow the slurry liquid at a high speed so that solid particles do not accumulate as a cake on the surface of the filtration layer, resulting in a disadvantage that large power costs are required.

は公害の点で問題があるなどの欠点があった。In addition, conventional filter presses used as concentrators have problems in terms of maintenance and energy saving, as they operate in batches and require frequent backwashing and regeneration because the filter media gets clogged quickly. Not only does the device require a large amount of power, but there is a limit to the separation, and the separation liquid contains quite a few small particles, so the separation efficiency is poor and the separation efficiency is low in the case of expensive particles or slurry liquid that contains harmful particles. There were some drawbacks, such as problems.

達成することができる。That is, the rotary continuous high-speed filter of the present invention rotates the vortex generating member to generate what is called a tiller vortex in mechanical engineering in the slurry liquid near the surface of the filter medium to prevent cake accumulation on the surface of the filter medium. This is a filter that performs cross-flow filtration by constantly cleaning the surface, and compared to conventional cross-flow filters, there is no need to flow the slurry liquid at high speeds, and in other words, the flow rate is small.In other words, it is possible to achieve high filtration speed with low power costs. can be obtained. In addition, when used as a filtration concentrator, not only can it be operated continuously, but if a filter material suitable for the slurry liquid is used, it can be separated with a separation efficiency of 100%, and furthermore, it is said that filtration SM can be performed with a small power cost. It is possible to achieve an energy-saving, high-precision, high-speed filter that has greatly improved the drawbacks of the above.

できる。(Effects of the Invention) As is clear from the detailed explanation above, according to the rotary continuous high-speed filter of the present invention, a vortex generating member is provided in the filter, and by rotating this member, the vortex is deposited on the filter medium. Since filter slag etc. are constantly removed, a higher filtration speed can be obtained compared to conventional cross-flow filters that do not have a vortex generating member, and processing can be performed using less power, resulting in energy savings and compactness. can. In addition, in the case of filtration and concentration, it is possible to obtain higher filtration speed and separation efficiency than with conventional cross-flow filters, etc., and continuous operation is possible, so energy saving, compactness, and maintenance can be achieved.
