Description
Technical field
The utility model relates to a kind of chemical experiment suction filtration device.
Background technology
In chemical experiment, often adopt the mode of filtering that sample is carried out Separation of Solid and Liquid.Simple utilize filter such as millipore filter etc. can only carry out natural filtration, and not only labour intensity is big, and inefficiency, has prolonged the whole chemical test cycle greatly.In order to accelerate the rate of filtration, the filtered fluid output with filter is communicated with suction filtration device of composition with air extractor usually.Can make the air pressure of filter filtered fluid output be lower than outside ambient atmosphere pressure by air extractor, promote sample solution to accelerate the pressure reduction that filters thereby produce, and then improve the rate of filtration.As present the most frequently used suction filtration device, mainly form by the Buchner funnel of making filter and bottle,suction and the air pump of making air extractor.The filtered fluid output of Buchner funnel is inserted in the bottle,suction in this suction filtration device, and the effect of bleeding by air pump makes in the bottle,suction and to form negative pressure and impel sample solution to accelerate to filter.Yet there is the shortcoming that once can only carry out Separation of Solid and Liquid to a kind of sample in above-mentioned suction filtration device, influences test efficiency.
The utility model content
The technical problem that the utility model solved is: a kind of chemical experiment suction filtration device that can be simultaneously two or more sample be carried out the Separation of Solid and Liquid operation is provided.
The technical scheme that solves the problems of the technologies described above is: chemical experiment suction filtration device, comprise filter and air extractor, and the filtered fluid output of at least two filters is communicated with air extractor by after the pipeline parallel connection.
For the rate of filtration to each filter is controlled separately, be provided with switch on the filtered fluid output of each filter.
The beneficial effects of the utility model are: adopt above-mentioned suction filtration device can realize simultaneously two or more sample is carried out the Separation of Solid and Liquid operation, and can not produce interference effect mutually each other.This device is applicable in the Chemical Manufacture work such as raw and auxiliary material, intermediate products and end article being carried out the chemical composition analysis detection, as detecting chemical composition content with gravimetric method or eliminating certain interference component with the precipitate and separate mode.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The suction filtration device of chemical experiment as described in Figure 1 comprises filter 11 and air extractor 12, and the filtered fluid output of at least two filters 11 is communicated with air extractor 12 by after the pipeline parallel connection.Can make the air pressure of the filtered fluid output of filter 11 be lower than outside ambient atmosphere pressure by air extractor 12, promote sample solution to accelerate the pressure reduction that filters thereby produce, and then improve the rate of filtration.Be communicated with air extractor 12 by after the pipeline parallel connection by filtered fluid output at least two filters 11, can avoid simultaneously the sample in each filter 11 being carried out the suction filtration operation on the interactional basis between the filter 11, thereby reach simultaneously the purpose that two or more sample is carried out the Separation of Solid and Liquid operation.Certainly, can either adorn with a kind of sample in each filter 11, also can adorn different samples, concrete use can be grasped by actual needs flexibly.
As shown in Figure 1, for the rate of filtration to each filter is controlled separately, be provided with switch 4 on the filtered fluid output of each filter 11.Can realize with different speed sample solution of different nature being operated synchronously simultaneously by switch 4 is set on the filtered fluid output of each filter 11, satisfy the rate request of different sample filterings, improve the popularity and the applicability of suction filtration device.In addition, before the filtered fluid in any one filter 11 wherein drains, should close switch 4 timely, can prevent that the suction filtration effect that air outside enters all the other filters 11 from impacting.
As shown in Figure 1, filter 11 can be selected multiple existing filtration facility for use according to the different qualities of filtered sample.The application provides a kind of novel filter 11, comprise micropore glass crucible 1, elastic caoutchouc circle 2 and have the separatory funnel 3 of switch 4 that the filtered fluid delivery outlet of described micropore glass crucible 1 and the input port of separatory funnel 3 are by 2 butt joints of elastic caoutchouc circle and be communicated with.Above-mentioned filter 11 is creationary will test the most frequently used several common equipment and assemble, because micropore glass crucible 1 is docked and connected by elastic caoutchouc circle 2 with separatory funnel 3, therefore the advantage that has easy disassembly between micropore glass crucible 1 and the separatory funnel 3, so just can be according to the character such as what and particle diameter of solid sediment, freely change, select for use the micropore glass crucible 1 of different size, model, the size that only need change elastic caoutchouc circle 2 gets final product.Therefore, adopt the filter 11 of said structure to change the vessel of perfect coupling with it flexibly, easily, make that the popularity of equipment for separating liquid from solid and applicability are stronger according to concrete test needs.
As shown in Figure 1, be communicated with air extractor 12 by after the pipeline parallel connection for the ease of filtered fluid output each filter 11, the filtered fluid output of each filter 11 is connected on each branch input port of multi-limbed tube 6, and total road delivery outlet of described multi-limbed tube 6 is communicated with air extractor 12.As Fig. 1, for the ease of filter 11 is connected with multi-limbed tube 6 respectively with air extractor 12, the filtered fluid output of each filter 11 is connected on each branch input port of multi-limbed tube 6 by plastic tube 5 respectively, and total road delivery outlet of described multi-limbed tube 6 is communicated with air extractor 12 by flexible pipe 7.
Described air extractor 12 can directly adopt mechanical pump.Certainly, in order to avoid the fault of mechanical pump as much as possible, reduce power consumption and maintenance cost, described air extractor 12 also can adopt structure as shown in Figure 2.This air extractor 12 comprises the closed container 8 that has water inlet 13 and delivery port 15, have on the wall of this container 8 and be used for the gas circuit arm 9 that is communicated with the filtered fluid output of filter 11, be provided with the interior pipe 14 that is communicated with described water inlet 13 in this container 8, the outlet of interior pipe 14 is near the delivery port 15 of container 8.To water inlet 13 water flowings, water is taken away the air in the container 8 when delivery port 15 flows out, thereby produces negative pressure in container 8 by water pipe 10.Enter air for fear of container 8, described delivery port 15 in tubular construction, described in pipe 14 outlet over against the upper port of this tubular structure, form liquid sealings at container 8 delivery ports 15 easily, prevent to enter air in the container 8.
In addition, when this suction filtration device used, the setting height(from bottom) of air extractor 12 should be lower than the setting height(from bottom) of filter 11, prevents that filtered fluid from overcoming gravity acting, improved suction filtration speed.
