Abstract
The utility model provides a vacuum continuously-stable guarantee system for pressure reduction and sucking filtration on water solution, which comprises a vacuum pump, a gas-washing bottle, a vacuum bottle, a sucking filtration bottle, a funnel and other components. The vacuum pump and the gas-washing bottle, the gas-washing bottle and the vacuum bottle and the sucking filtration bottle are respectively connected by glass pipes, wherein the glass pipes of the vacuum bottle and the sucking filtration bottle are provided with tee plugs; the vacuum bottle is provided with a vacuum gauge; and the funnel is arranged on the sucking filtration bottle. The utility model has the advantages of simple structure, convenient use and the like.
Description
Technical field
The utility model relates to the equipment that a kind of laboratory aqueous sample is analyzed pre-treatment, the i.e. continual and steady safeguards system of aqueous solution decompress filter vacuum.
Background technology
Decompress filter is vacuum filtration, suction strainer again, is to utilize vavuum pump or aspiration pump will take out air in (suction) filter flask to take away and produce negative pressure, and the rate of filtration is accelerated.The decompress filter device is made up of vavuum pump, bottle,suction, funnel, and traditional decompress filter is that bottle,suction is connected with vavuum pump, and the centre connects a Drexel bottle and an insurance bottle at most again.If only filter a sample, and sample size (volume) hour, this system simple and feasible when running into the big or batch samples of single sample amount and will filter, need vacuumize (opening, close vavuum pump) continually, go vacuum in (by the plug vacuum tube) in the course of work.Complex operation after time-consuming taking a lot of work, particularly sample filtering are intact, just can take off funnel after residual vacuum such as palpus exhaust, inefficiency, and the vavuum pump wearing and tearing are big, and power consumption is many.
Summary of the invention
The purpose of this utility model just provides the continued stable safeguards system of a kind of vacuum, this system is by vavuum pump, Drexel bottle, Dewar bottle, parts such as bottle,suction and funnel are formed, between described vavuum pump and the Drexel bottle, between Drexel bottle and the Dewar bottle, be connected by glass tube between Dewar bottle and the bottle,suction, the glass tube that wherein connects Dewar bottle and bottle,suction is provided with stop,threeway, Dewar bottle is provided with vacuum meter, described funnel is installed on the bottle,suction, form by upper hopper and following funnel, be provided with the web plate that filters usefulness between upper hopper and following funnel, following funnel neck also is provided with the rubber sleeve plug, thereby can guarantee that funnel and bottle,suction junction are airtight air tight when working.Described vavuum pump vacuumizes, and is the vacuum source of whole system; The concentrated sulfuric acid is housed in the Drexel bottle is used to dry, i.e. absorption enters the airborne moisture of vavuum pump, prevents ponding in the vavuum pump, cause corrosion, Dewar bottle is used to store vacuum, makes this system provide continual and steady vacuum to become possibility, vacuum meter is housed, so that watch the negative pressure of vacuum value at any time on it; Stop,threeway can be done following operation at any time as required: (1) airtight vacuum bottle, and when vacuumizing, finishes Dewar bottle this operation; (2) be communicated with Dewar bottle and bottle,suction, finish this operation during vacuum filtration; (3) make bottle,suction lead to atmosphere, finish filtration after, must get rid of the vacuum in the bottle,suction so that take out funnel, take out filtrate, and ready for filtering next sample.
The utlity model has characteristics such as simple in structure, easy to use.

The specific embodiment
Contrast Fig. 1, Fig. 2 as can be known, the utility model is by vavuum pump 1, Drexel bottle 2, Dewar bottle 3, bottle,suction 4 and funnel 5 are formed, between described vavuum pump 1 and the Drexel bottle 2, between Drexel bottle 2 and the Dewar bottle 3, be connected by glass tube between Dewar bottle 3 and the bottle,suction 4, the glass tube that wherein connects Dewar bottle 3 and bottle,suction 4 is provided with stop,threeway 7, Dewar bottle is provided with vacuum meter 8, described funnel 5 is installed on the bottle,suction 4, form by upper hopper 9 and following funnel 10, be provided with the web plate 11 that filters usefulness between upper hopper 9 and following funnel 10, following funnel neck also is provided with rubber sleeve plug 12.
Operation principle of the present utility model is as follows:
(1) vacuum is prepared: revolve stop,threeway to the logical atmosphere position of bottle,suction, the airtight vacuum bottle starts vavuum pump, watches vacuum meter, when reaching 0.60-0.80atm etc. negative pressure, closes vavuum pump.
(2) bottle,suction is prepared: be ready to bottle,suction, install funnel.
(3) suction filtration process: add the aqueous solution to be filtered in upper hopper, filtration begins immediately, after finishing, revolve stop,threeway to the logical atmosphere of bottle,suction, at this moment can easily take off funnel part, from bottle,suction, pour out filtrate, clean bottle,suction and funnel, then filter next sample.10 (1000mL) are generally filtered in so cycling approximately, and negative pressure obviously descends when causing the rate of filtration slow, opens vavuum pump, increases the negative pressure of Dewar bottle.
In this system, adjunction Dewar bottle (being equipped with vacuum meter), three-way cock.The both competent single sample amount of this system is big, and the laboratory sample of competent batch samples vacuum filtration is analyzed pre-treatment work again.In addition, by this system, the laboratory can obtain negative regulation, and the vacuum condition of longer duration has in the laboratory more widely and uses relatively.
Claims (2)
1. continual and steady safeguards system of aqueous solution decompress filter vacuum, it is characterized in that forming by vavuum pump (1), Drexel bottle (2), Dewar bottle (3), bottle,suction (4) and funnel (5), between described vavuum pump (1) and the Drexel bottle (2), between Drexel bottle (2) and the Dewar bottle (3), be connected by glass tube between Dewar bottle (3) and the bottle,suction (4), the glass tube that wherein connects Dewar bottle (3) and bottle,suction (4) is provided with stop,threeway (7), Dewar bottle is provided with vacuum meter (8), and described funnel (5) is installed on the bottle,suction (4).
