Abstract
The utility model provides a vacuum filtration device for secondary filter. The vacuum filtration device comprises a first hopper, a connecting piece, a second hopper and a filter flask, wherein the first hopper and the second hopper are connected through the connecting piece, the second hopper is connected with the filter flask, the diameter of the lower end connecting part of the first hopper is equal to that of the upper end connecting part of the second hopper, and the diameter of a filtering hole of the first hopper is larger than that of a filtering hole of the second hopper. The vacuum filtration device has the benefits as follows: two times of filer can be completed simultaneously, the operation is simple, and time is saved; and meanwhile, the purity of filtrate can be guaranteed, or the mass of a filter cake can be increased, the filter efficiency is high, and the effect is good.
Description
Technical field
The utility model belongs to filter technical field, relates in particular to a kind of secondary filter vacuum filtration device.
Background technology
At present, the suction filtration device that industry or simple scientific experiment are used on the market has a variety of, decompress filter is the operating procedure often using in experimental implementation process, decompress filter claims again vacuum filtration, suction strainer, to utilize vavuum pump or aspiration pump that the air of taking out in (suction) filter flask is taken away and produced negative pressure, the equipment that the rate of filtration is accelerated.When solution filtration in chemical analysis method at present, the filter adopting is made up of bottle,suction and funnel, and it is simple in structure.In the time that filtrate is required product, often need to carry out secondary filter by filtering for the first time the filtrate obtaining, to increase purity, when operation, need to first disconnect vavuum pump, liquid rotating in bottle,suction is moved on in other containers and carries out secondary filter again, and still operation is more loaded down with trivial details like this, and loses time.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of secondary filter vacuum filtration device, can complete twice filtration simultaneously, simple to operate, save time, can ensure the purity of filtrate simultaneously, or the quality that increases filter cake, filter efficiency is high, effective.
To achieve these goals, the utility model adopts following technical scheme: a kind of secondary filter vacuum filtration device, it is characterized in that comprising the first funnel, connector, the second funnel, bottle,suction, described the first funnel is connected by described connector with described the second funnel, described the second funnel is connected with described bottle,suction, the upper end connecting portion diameter of the lower end connecting portion of described the first funnel and described the second funnel matches, and the pore size filter of described the first funnel is greater than the pore size filter of described the second funnel.
Described the first funnel, described the second funnel are respectively Buchner funnel, and described connector is rubber tube.
Described the first funnel, described the second funnel are respectively sand core funnel, between described the first funnel and described the second funnel, are connected by ground adapter.
The beneficial effects of the utility model are: due on have two funnels, so can complete twice filtration, by controlling the difference in filter paper or filter aperture, make upper and lower two funnels realize respectively coarse filtration and essence filtration simultaneously, improve the precision of filtering, and simple to operate, save time, with low cost, can ensure the purity of filtrate simultaneously, or the quality that increases filter cake, filter efficiency is high, good filtration effect.

In figure, 1, the first funnel, 2, connector, 3, the second funnel, 4, bottle,suction, 5, micro-porous filtration plate, 6, suction filtration tank, 7, rubber stopper, 8, suction filtration mouth.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is explained.
As shown in Figure 1 and Figure 2, the utility model provides a kind of secondary filter vacuum filtration device, it is characterized in that comprising the first funnel 1, connector 2, the second funnel 3, bottle,suction 4, the first funnel 1 is connected by connector 2 with the second funnel 3, the second funnel 3 is connected with bottle,suction 4, the upper end connecting portion diameter of the lower end connecting portion of the first funnel 1 and the second funnel 3 matches, and the pore size filter of the first funnel 1 is greater than the pore size filter of the second funnel 3.
Embodiment 1: as shown in Figure 1, the first funnel 1, the second funnel 3 are respectively Buchner funnel, connector 2 is rubber tube, realize being tightly connected of upper end the first funnel 1 and lower end the second funnel 3 by rubber tube, while being convenient to suction filtration, keep good sealing, the filter paper of the first funnel 1, the interior placement different pore size of the second funnel 3, to reach twice filtration in various degree.
Embodiment 2: as shown in Figure 2, the first funnel 1, the second funnel 3 are respectively sand core funnel, the lower edge of the first funnel 1 is made to ground structure, the upper end-face edge of the second funnel 3 is made to ground structure, then between the first funnel 1 and the second funnel 3, just can be connected by ground adapter, smear silicone oil at ground place and the first funnel 1 is connected with the second funnel 3 and keep good sealing can be at suction filtration time.Sand core funnel is by for micro-porous filtration plate 5 and suction filtration tank 6 form, and micro-porous filtration plate 5 apertures of the first funnel 1 are greater than micro-porous filtration plate 5 apertures of the second funnel 3.
Example: the first funnel 1 is connected by connector 2 with the second funnel 3, the second funnel 3 is connected by rubber stopper with holes 7 with bottle,suction 4, water pump is connected with the suction filtration mouth 8 of bottle,suction 4, fix respectively the first funnel 1 and the second funnel 3 with iron stand, complete the installation of suction filtration device, when use, open water pump.
Above example of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
