Description
Technical Field
The utility model belongs to the experimental facilities field, in particular to quick filter equipment in multiunit vacuum.
Background
Filtration is a method of separating liquid-insoluble solid matter from a liquid, and is often required in laboratories. At present, in a vacuum filtration apparatus in a laboratory, a funnel is inserted into a filtration bottle, an interface of a filtration pump is connected with the filtration bottle by using a pipeline, and the filtration pump is started to form a negative pressure environment in the filtration bottle, so that solid substances in liquid are separated from the liquid.
However, the traditional equipment can only realize the filtration treatment of one funnel and one filter flask at a time, and the filtration efficiency is low. How to improve the filtration treatment efficiency under the laboratory condition is an urgent problem to be solved.
Disclosure of Invention
Problem to prior art existence, the utility model aims at providing a multiunit vacuum rapid filtration device can realize the rapid filtration in the time of multiunit sample simultaneously, improves test efficiency, avoids polluting mutually between the different samples, practices thrift the cost.
The utility model aims at realizing through the following technical scheme:
the utility model provides a quick filter equipment in multiunit vacuum, includes sealed container, funnel and vacuum pump, sealed container comprises top cap and vessel, the funnel is prefabricated on sealed container's top cap, and the quantity of funnel is 2 at least, and the below of every funnel passes through buckle sealing connection liquid collecting bottle, and the vacuum pump is connected through the rubber tube in one side of vessel.
Further, the funnel is a sand core funnel; the number of the funnels is 4-8.
Furthermore, the top cover and the container body are both made of glass.
Furthermore, a rubber pad is arranged between the funnel and the liquid collecting bottle for sealing.
The utility model discloses compare prior art's beneficial effect does:
multiunit vacuum rapid filtration device, can realize that multiunit sample carries out filtration simultaneously, filterable sample simultaneously can be same article, also can be different samples, has so not only improved the laboratory greatly and has carried out filtration treatment's efficiency, has still avoided different samples to carry out filtration treatment, the problem of the mutual pollution that probably produces is fit for different extraction condition screening experiments in advance.

Fig. 1 is a schematic structural view of a plurality of vacuum rapid filtering devices according to an embodiment of the present invention;
fig. 2 is a top view of fig. 1.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the present embodiment provides a multi-group vacuum rapid filtering apparatus, which includes a sealed container 1, a sand core funnel 2 and a vacuum pump 3, wherein the sealed container is composed of a top cover 1-1 and a container body 1-2, both of which are made of organic glass, and can bear a lower internal negative pressure, thereby ensuring the stability of the entire apparatus. 8 husky core funnels divide into two rows that parallel, prefabricate on sealed container's top cap, and buckle sealing connection liquid collecting bottle 4 is passed through to the below of every funnel, strengthens sealed effect through the rubber pad between liquid collecting bottle and the husky core funnel, and vacuum pump 3 is connected to one side of vessel.
According to the requirements of different filtering conditions, aluminum films with different apertures can be placed in the sand core funnel, so that different actual requirements are met. The sand core funnel is prefabricated on the glass top cover, and the leakproofness is good, also can guarantee effective negative pressure for long-term use. The glass material can bear lower inside negative pressure, has guaranteed the stability of device, and the filter effect is higher. The liquid collecting bottle and the sand core funnel are standard interfaces, and corresponding collecting bottles can be selected for different volumes of filter liquid to perform experiments.
The using method of the device comprises the following steps:
and opening the glass top cover, screwing the liquid collecting bottle below the corresponding sand core funnel according to the filtering volume, and tightly covering the glass top cover. The 0.45 micron filter membrane was placed in a sand core funnel, the vacuum pump was turned on, and the pressure gauge was observed. And adding a plurality of groups of samples to be separated into each sand core funnel when the negative pressure condition is stable. And pulling off a rubber tube connected with the vacuum pump and the device after the sample passes through the sand core funnel, and closing the vacuum pump. And opening the glass top cover, and sequentially taking down the liquid collecting bottles to finish the multi-component solid-liquid separation operation.
Extracting and analyzing volatile components of commercially available white tea serving as an extract, accurately weighing a certain amount of tea leaves, crushing the tea leaves, sieving the tea leaves with a 60-mesh sieve to obtain constant-weight tea powder, adding an ethanol solution into the constant-weight tea powder according to a certain liquid-material ratio, placing the constant-weight tea powder into a round-bottom flask, leaching for a certain time at a certain temperature, and taking out the constant-weight tea powder. Select the quick filter equipment in multiunit vacuum of this embodiment, screw up the liquid collecting bottle in husky core funnel below that corresponds, cover glass top cap. The 0.45 micron filter membrane was placed in a sand core funnel, the vacuum pump was turned on, and the pressure gauge was observed. And (3) when the negative pressure condition is stable, sequentially and respectively adding 1-8 groups of mixtures after extraction, enabling the samples to quickly enter a liquid collecting bottle through a sand core funnel, and taking the samples of the liquid collecting bottle for UV analysis.
