专利汇可以提供Filtration apparatus专利检索，专利查询，专利分析的服务。并且Filtration apparatus for filtering radioactive or highly toxic materials includes a filter tank and a disposable filter cartridge removably mounted in the tank and including a plurality of filter rolls and a rotatable take-up spool mounted in a perforate container. The take-up spool mates with a drive shaft in the tank and is rotated to remove the plugged outer windings or layers from the rolls to expose a fresh filtering surface. After the filter rolls have been completely unwound, the filter cartridge, including the used filter material and any filter cake which may have been deposited thereon can be removed from the tank and replaced with a fresh cartridge without exposure to the operating personnel.，下面是Filtration apparatus专利的具体信息内容。
1. Filtration apparatus comprising a filter tank defining a filter chamber and having an inlet and an outlet; a perforate container adapted to be removably supported within said chamber; means for removably mounting said container in said chamber; at least one filtration unit mounted in said container, said unit including a perforate hollow support and a plurality of contiguous layers of a filter material wound on said perforate hollow support to form a roll; a take-up spool rotatably mounted in said container and adapted to be connected to the filter material on said hollow support; means for detachably connecting said hollow support to said outlet in fluid communication therewith; driving means for rotating said spool to unwind said filter material from said support, said driving means having an output; and means for detachably connecting said output of said driving means to said spool, whereby said container and its contents can be removed as an assembled unit from said tank when said filter material becomes exhausted and a fresh container replaced in said tank.
2. Filtration apparatus according to claim 1, wherein said means for removably mounting said container in said chamber comprises a plurality of mounting brackets secured to the inner wall of the filter tank for supporting said container from below, said container resting on the top surfaces of said brackets.
3. Filtration apparatus according to claim 1, wherein said means for detachably connecting said hollow support to said outlet includes a tubular connector connected in fluid communication with said hollow support and extending through an aperture in the bottom wall of said container, and a female connector connected in fluid communication with said outlet for receiving said connector.
4. Filtration apparatus according to claim 3, further including a resilient O-ring surrounding said tubular connector to seal the tubular connector to said female connector.
5. Filtration apparatus according to claim 3, wherein means for detachably connecting said output of said driving means to said spool includes a female connector fixedly connected to said output of said driving means for receiving an end portion of said spool extending through an aperture in the bottom wall of said container.
6. Filtration apparatus according to claim 5, further including a pair of guide strips secured to and extending along opposite sides of the perforate container on the outside thereof and a pair of guide tracks extending along opposite sides of the inner wall of the filter tank to receive said guide strips therebetween to guide the container as it is inserted into the filter chamber so that the tubular connector is positioned in proper alignment with its female connector and said spool is positioned in proper alignment with said female connector of said drive means.
7. A cartridge adapted for use in a filter tank having an inlet and an outlet and having supporting means for removably mounting said cartridge in its filter chamber, said tank including driving means, said cartridge comprising: a perforate container adapted to be removably supported by said supporting means within said filter chamber of said filter tank; at least one filtration unit mounted in said container and having means adapted to be removably connected in fluid communication to said outlet, said unit including a perforate hollow support and a plurality of contiguous layers of a filter material wound on said hollow support to form a roll; and a take-up spool in said container adapted to be drivingly and removably connected to said driving means and adapted to be connected to the filter material on said hollow support so that said driving means can rotate said spool to unwind said filter material from said support, whereby said container and its contents can be removed as an assembled unit from said tank when said filter material becomes exhausted and a fresh container replaced in said tank.
8. A cartridge according to claim 7, wherein said tank includes a pair of guide tracks extending along opposite sides of the inner walls thereof, said cartridge including a pair of guide strips secured to and extending along opposite sides of the perforate container on the outside thereof, said strips being adapted to be received by said guide tracks to guide the container as it is inserted into the filter chamber.
