Abstract
The utility model relates to a laboratory suction filtration device, which comprises a Buchner funnel, a suction filtration bottle, a bottle plug, a measuring cylinder frame, a filtrate measuring cylinder, an exhaust pipe, a cock, a leather hose and an exhaust pump, wherein the Buchner funnel is made of transparent glass; scales are marked at the upper part of the funnel; the upper end of the measuring cylinder frame is fixed on the bottle plug; the elastic leather hose in the middle is used for fixing the filtrate measuring cylinder; the filtrate measuring cylinder is made of transparent glass; scales are marked on the filtrate measuring cylinder; the exhaust pipe passes through the bottle plug; the cock is at the upper part of the exhaust pipe; the exhaust pump is connected with the suction filtration bottle through the leather hose. According to the utility model, because the Buchner funnel is made of transparent glass and the scales are marked on the funnel, the thickness of a filter cake can be directly red, and therefore, the thickness of the filter cake is measured simply and accurately; because the filtrate measuring cylinder is additionally arranged, the volume of filtrate is rapider and more accurate to measure; furthermore, by means of the laboratory suction filtration device disclosed by the utility model, the efficiency and the accuracy of laboratory filtering tests are increased.
Description
Technical field
The utility model relates to a kind of laboratory suction filtration device.
Background technology
Filtration refers to and utilizes aspiration pump that the pressure in bottle,suction is reduced, and reaches the object method of Separation of Solid and Liquid, in laboratory, conventionally utilizes this principle to carry out Separation of Solid and Liquid, and studies the filtering property of material by measuring filter cake thickness, filtrate volume etc.In at present conventional laboratory suction filtration device, Buchner funnel+bottle,suction+aspiration pump is most typical device.In the time using this device, after filter cake need to being taken out from the Buchner funnel of filter, measure again its thickness, the process that soft filter cake takes out from funnel is more difficult, and easily causes filter cake breakage, distortion, thus the measurement result of having influence on.In conventional laboratory suction filtration device, filtrate bottle is long-pending larger, collects filtrate inconvenience, and it is larger that filtrate is bonded at loss amount on bottle wall, causes the accuracy of experiment inadequate.So the purpose of this utility model is to provide a kind of high efficiency laboratory suction filtration device that can quick and precisely measure filter cake thickness, filtrate volume.
Summary of the invention
The purpose of this utility model is to provide a kind of laboratory suction filtration device, can quick and precisely measure filter cake thickness, filtrate volume, improves conventional efficient and the degree of accuracy.
Object described in the utility model is achieved through the following technical solutions: a kind of laboratory suction filtration device, comprise Buchner funnel, bottle,suction, bottle stopper, cylinder rack, filtrate graduated cylinder, blast pipe, cock, leather hose, aspiration pump, described Buchner funnel lower tubular part enters bottle,suction through bottle stopper; Described filtrate graduated cylinder be vertically mounted on Buchner funnel under, the filtrate of flowing out for accepting Buchner funnel; Described Buchner funnel is clear glass material, and funnel top is divided and indicated scale; Described cylinder rack upper end is fixed on bottle stopper, and there is an elasticity apron centre for fixing filtrate graduated cylinder; Described filtrate graduated cylinder is clear glass material, indicates scale; Described blast pipe is applied in bottle stopper, and top is with cock; Described aspiration pump is connected by leather hose and bottle,suction.
After having tested, close aspiration pump, open cock and make bottle,suction inner and outer air pressure identical, conveniently take off bottle stopper, thereby taking-up filter cake and filtrate are to test next time.
The beneficial effects of the utility model are: owing to using the Buchner funnel of clear glass material, and be marked with scale at funnel, can directly read the thickness of filter cake, the measurement of filter cake thickness is become simply, accurate.Owing to having added filtrate graduated cylinder, can be sooner, the more accurate filtrate volume of measuring.Whole device has improved efficiency and the degree of accuracy of laboratory filtration test.
