Abstract
The utility model provides a combined drawing and filtering device capable of automatically discharging liquid. The combined drawing and filtering device comprises a funnel and a drawing and filtering bottle connected with the funnel, wherein a liquid discharging pipe is mounted on one side wall of the middle part of the drawing and filtering bottle; a pipe opening of the liquid discharging pipe, which is positioned at the inner part of the drawing and filtering bottle, is placed at the bottom of the drawing and filtering bottle; a cock is mounted at a pipe opening of the liquid discharging pipe, which is positioned at the outer part of the drawing and filtering bottle; the funnel comprises a funnel-shaped support frame at the bottom of the funnel, wherein the upper end of the support frame is connected with a cylinder, and the lower end of the support frame is connected with the drawing and filtering bottle; and a filtering screen is paved on the upper end surface of the support frame. The combined drawing and filtering device has a reasonable design and a simple structure, is easy to realize, and has the advantages that dead corners can be effectively eliminated and cleaned, material cross infection caused by non-thorough cleaning is avoided, automatic liquid discharge of the drawing and filtering bottle is realized in the operation process, and the disadvantage of operation interruption caused by liquid discharging or vacuum pump pollution caused by inverse suction of solution is avoided.
Description
Technical field
The utility model relates to a kind of chemical experimental instrument, but specifically is a kind of combination suction filtration device of automatic drain.
Background technology
The suction filtration device is chemical laboratory a kind of laboratory apparatus commonly used, and normally used funnel is the overall structure formula, after suction filtration finishes; Inside is difficult to clean up; Especially during the suction filtration thick liquid, stick to inwall or dead angle place more easily, bring difficulty to cleaning; If clean not thoroughly, cause the material cross-infection easily; In addition; The bottle,suction of suction funnel is finite capacity often, and is big or when producing the more solution of foam at the suction filtration volume, in the middle of needing once or interrupt operation for several times; Discharge the filtrating in the bottle,suction; If it is untimely to discharge filtrating, can cause that also solution or foam suck-back go in the vacuum system, cause that vavuum pump pollutes.
Summary of the invention
But the utility model technical problem to be solved provides a kind of combination suction filtration device of automatic drain, this device can be in operating process with the filtrating in the bottle,suction in time, automatically discharge.
For addressing the above problem; The technical scheme that the utility model adopts is: but a kind of combination suction filtration device of automatic drain; Comprise funnel and connected bottle,suction; On the sidewall at bottle,suction middle part discharging tube is housed, discharging tube places the bottle,suction bottom at the inner mouth of pipe of bottle,suction, and discharging tube is equipped with cock at the outside mouth of pipe place of bottle,suction.During suction filtration, when liquid level reach discharging tube go out open height the time, open cock, liquid promptly flows out from discharging tube.
Described funnel comprises the funnel type bracing frame of bottom, and the upper end of bracing frame connects a cylinder, and the lower end connects bottle,suction, and the upper surface tiling of bracing frame has filter screen.After suction filtration finishes, cylinder, filter screen taken off respectively from bracing frame clean, be easy to clean up, time saving and energy saving.
The utility model is reasonable in design, and is simple in structure, is easy to realize.It is also advantageous in that: (1) combined funnel can be eliminated effectively and clean the dead angle; Avoided owing to cleaning the not thorough material cross-infection that causes; (2) bottle,suction that has leakage fluid dram realized bottle,suction automatic drain in the operating process, avoided polluting because of discharge opeing and interrupt operation or solution suck-back the drawback of vavuum pump.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1-funnel, 2-bottle,suction, 3-discharging tube, 4-cock, 5-bracing frame, 6-cylinder, 7-filter screen, 8-sealing ring, 9-vacuum orifice.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be specified.
But the combination suction filtration device of the described a kind of automatic drain of the utility model; Comprise funnel 1 and connected bottle,suction 2; On the sidewall at bottle,suction 2 middle parts discharging tube 3 is housed; Discharging tube 3 places bottle,suction 2 bottoms at the bottle,suction 2 inner mouths of pipe, and discharging tube 3 is equipped with cock 4 at bottle,suction 2 outside mouth of pipe places.Funnel 1 and bottle,suction 2 are with grinding port plug or be socketed with rubber stopper with holes and be connected, and the bottle,suction side is provided with known vacuum orifice 9, and inner discharging tube 3 extends near the bottle,suction bottom with vertical direction.
Funnel 1 comprises the funnel type bracing frame 5 of bottom, and the upper end of bracing frame 5 connects a cylinder 6, and cylinder 6 is connected with bracing frame 5 with knob or plug-in type, and the lower end connects bottle,suction 2, and the upper surface tiling of bracing frame 5 has filter screen 7.Filter screen 7 is sandbox filter screen or type filter screen with holes, is lined with sealing ring 8 between filter screen 7 and the bracing frame 5.
When preparing suction filtration, earlier cylinder 6 is connected with bracing frame 5, successively sealing ring 8 and filter screen 7 is placed on the bracing frame then; Funnel 1 and bottle,suction 2 are connected, close the outside cock 4 of discharging tube 3, filter paper is tiled on the filter screen 7 begins suction filtration then; When liquid level reach discharging tube 3 go out open height the time, open cock 4, liquid promptly flows out from discharging tube 3; After suction filtration finishes, cylinder 6, filter screen 7 and sealing ring 8 taken off respectively from bracing frame 5 clean.
