Abstract
The invention relates to a device for filtering a negative pressure solution. The device is composed of a closed container, a filtering plate chamber and a vacuum pumping port, a container for a to-be-filtered solution, a container for a filtered solution, a seal ring and a switch, wherein the bottom of the container for the to-be-filtered solution is connected with the filtering plate chamber, and the filtering plate chamber is internally provided with a gasket and a multi-hole filtering plate; a bottom pipeline passes through the seal ring, and enters the container for the filtered solution in the closed container, the closed container is provided with the vacuum pumping port, and the switch is arranged between the container for the to-be-filtered solution and the filtering plate chamber. The device provided by the invention has the advantages that the closed container is vacuumized, and differential pressure is generated between inside and outside of the container, so that a solution enters in the container through the device, and further, the purpose of filtering the solution is achieved, and the operation is rapid and convenient.
Description
Technical field
The present invention relates to a kind of device under condition of negative pressure, different solutions being filtered, utilize this device to filter impurity or the particle of different solutions (organic and inorganic).
Background technology
When solution being carried out to chemical analysis (ion component in solution or content), often to carry out early stage to analytic sample and process, comprising funnel, add the filtration of filter paper and the precipitation of use centrifuge.But these processing methods have its shortcoming: funnel adds the filtration of filter paper, and the time is longer, and filter paper easily damages, and affect the purity of sample; Use the precipitation of centrifuge, although the filtering-depositing time is very fast, its floating thing above solution and the suspension in solution remain, and must again process, and not only bother but also time-consuming.Developed a kind of negative pressure solution filtering device necessary for this reason.
Summary of the invention
For the deficiencies in the prior art, object of the present invention aims to provide a kind of device of negative pressure solution filter.This device can meet impurity or the particle of different solutions (organic and inorganic) are filtered.
The object of the invention is to be achieved through the following technical solutions:
A kind of device of negative pressure solution filter, mainly by closed container, filter chamber, vacuum orifice, the solution container being filtered, solution container after filtration, sealing ring and switch form, and the solution container bottom being filtered is connected with filter chamber, indoor pad and the porous filter plate of being equipped with of filter, its bottom pipe enters the solution container after closed container inner filtration through sealing ring, and closed container is provided with vacuum orifice, between the solution container being filtered and filter chamber, is provided with switch.
Advantage of the present invention:
The present invention utilizes this device vacuumizes (negative pressure) and different pore size filter by vavuum pump to different solutions is carried out to filtration treatment, not only soon but also convenient, overcome filtration, the filter paper that existing funnel adds filter paper and easily damaged, affected the filtration purity of sample and the centrifuge repeatedly floating thing above solution and the suspension in solution, the defect that wastes time and energy.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is filter chamber schematic diagram in Fig. 1.
The specific embodiment
A device for negative pressure solution filter, mainly by closed container 4, filter chamber 2, vacuum orifice 3, the solution container 1 being filtered, the solution container 5 after filtration, sealing ring 6 and switch 7 form.Solution container 1 bottom being filtered is connected with filter chamber 2, and filter chamber 2 is built-in with tetrafluoroethene pad 8 and two floor porous filter plate 9.Two layers of porous filter plate at the middle and upper levels filter aperture is 0.1mm, and lower floor's filter aperture is 0.01mm.Filter chamber 2 bottom pipe enter the solution container 5 after closed container 4 inner filtrations through sealing ring 6, and closed container 4 is provided with vacuum orifice 3, and 2 of the solution container 1 being filtered and filter chambers are provided with switch 7
Vavuum pump connects vacuum orifice 3.In use procedure, first closing switch 7, by 3 pairs of closed containers 4 of vacuum orifice, vacuumize, closed container 4 is inside and outside will produce pressure reduction, and the solution that will filter is poured in the solution container 1 being filtered simultaneously, in the situation that vacuum reaches 0.2Mpa, open switch 7, the solution being at this moment filtered will arrive in the solution container 5 after filtering, in the process of solution filter by upper and lower two-layer filter, continuation vacuumizes closed container, until solution filter completes.
