Abstract
The utility model discloses a vacuum filtering device of a porous filtering plate. The vacuum filtering device comprises a box body and a cover body matched with the box body in size, wherein a silica gel sealing gasket for sealing the box body and the cover body in a filtering process is arranged between the box body and the cover body; the cover body is provided with an embedding hole for embedding the porous filtering plate; an upper silica gel sealing gasket is arranged at a hollow edge part of the embedding hole on the cover body; and the box body is provided with a pipe-shaped air exhausting opening which is used for communicating the inner part and the outer part of the box body. According to the vacuum filtering device of the porous filtering plate disclosed by the utility model, the cover body and the box body can be separated and a dead angle between the cover body and the box body is not generated, so that filtering liquid is easy to pour and recycle, the recycling is more complete and the washing and maintenance are convenient.
Description
Technical field
The utility model relates to a kind of vacuum filtration device, specifically relates to a kind of vacuum filtration device that porous filter plate filtered or cleaned use that is applicable to.
Background technology
In the biochemistries such as protein purification, nucleic acid preparation, new medicament screen, medicine and pharmacology experiment, especially in the processes such as solid phase extractions, component purification, magnetic beads analysis or product recovery, the commonly used filtration to micro-porous filtration plate cleaned or filtered and recycled.Existing micro-porous filtration plate vacuum filtration device, its lid and filtrate container are generally integral structure, owing between lid and filtrate container, the dead angle being arranged, filtrate easily remains in the dead angle when toppling over recovery, cause and reclaim incomplete, cleaning difficulty, the secondary that affects this micro-porous filtration plate vacuum filtration device uses.
The utility model content
The purpose of this utility model is to provide a kind of being applicable to of solving the problems of the technologies described above, and porous filter plate filters or the vacuum filtration device of cleaning use, and this porous filter plate generally refers to micro-porous filtration plate.The purpose of this utility model realizes by following technical proposals:
A kind of porous filter plate vacuum filtration device, comprise a casing and a lid that matches with its size, be provided with a silica gel sealing packing ring that casing and lid are sealed between described casing and described lid, offer the filter bores of filtering for porous filter plate on described lid, on described lid, described filter bores edge is provided with the silica gel sealing packing ring, be equiped with to be communicated with box house and outside tubulose bleeding point on described casing.
The utility model further, described casing is cuboid.
The utility model further, described casing upper end offers be used to the groove of placing described silica gel sealing packing ring.
Application of the present utility model is implemented its remarkable technique effect is mainly reflected in: due to lid and casing separable, do not produce the dead angle between lid and casing, filtrate toppled over reclaim easily, reclaim fully, clean and maintenance is convenient.
Following constipation closes accompanying drawing, the specific embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
Description of drawings
Fig. 1 is the structural representation of the utility model porous filter plate vacuum filtration device.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described, for embodiment the utility model is made the generality illustration, help to understand better the utility model, but can't limit the utility model scope.
See also Fig. 1, the utility model porous filter plate vacuum filtration device, comprise a casing 1 and a lid 2 that matches with its size, be provided with a silica gel sealing packing ring 3 that casing 1 and lid 2 are sealed between described casing 1 and described lid 2, offer the filter bores of filtering for porous filter plate on described lid 2, on described lid 2, described filter bores edge is provided with silica gel sealing packing ring 4, be equiped with to be communicated with the inside and outside tubulose bleeding point 5 of casing 1 on described casing 1.
This porous filter plate vacuum filtration device particularly, described casing 1 is cuboid, and offer be used to the groove of placing described silica gel sealing packing ring 3 in described casing 1 upper end, play the effect of strengthening casing 1 and lid 2 tight seal in the vacuum filtration process.With cuboid casing 1 accordingly, described lid 2 is the rectangle cover plate, described silica gel sealing packing ring 3 is rectangle ring spacers, and because normally used porous filter plate is the tabular structure of rectangle, the filter bores of the filtration use of therefore offering on described lid 2 is the rectangle perforate.
When the utility model uses, at first silica gel sealing packing ring 3 is placed in the groove of casing 1 upper end offering, cover lid 2, again upper silica gel sealing packing ring 4 is placed on lid 2, then porous filter plate (not shown on figure) is placed on upper silica gel sealing packing ring 4, the porous filter plate periphery is fitted with silica gel sealing packing ring 4, form thus the relative airtight vessel space that is consisted of by above-mentioned casing 1, lid 2, silica gel sealing packing ring 3, upper silica gel sealing packing ring 4 and porous filter plate.Connect the bleeding point 5 of vavuum pump to the casing 1 with exhaust tube at last, open vavuum pump, can carry out air exhaust filtering to porous filter plate.
Above, adopt lid 2 and the casing 1 of the utility model porous filter plate vacuum filtration device separable, do not produce the dead angle between lid 2 and casing 1, filtrate toppled over reclaim easily, reclaim fully, clean and maintenance conveniently.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
