Abstract
The utility model belongs to the field of chemical experiment apparatuses and in particular discloses a novel suction flask. The suction flask comprises a flask neck, a flask body and a suction nozzle, wherein the flask body comprises an inner flask body and an outer flask body; a U-shaped channel is formed between the inner flask body and the outer flask body; the inner flask body and the outer flask body share the same flask neck; a vent hole is formed in the upper part of the side wall of the inner flask body; the suction nozzle is formed in the upper part of the side wall of the outer flask body; a liquid outlet with a plug is formed in the bottom of the side wall of the outer flask body. The suction flask has the advantages of convenience in operation and reverse suction prevention.
Description
Technical field
The utility model relates to a kind of bottle,suction, particularly a kind of reverse-suction-proof suction filtration bottle.
Background technology
Filtration is the conventional solid, liquid phase mixture separation method in a kind of laboratory.But the solution large to some concentration, or filtration flow-rate very slowly in situation, needs to adopt filtration under diminished pressure in normal pressure situation.Bottle,suction, as the utensil of accelerating flow velocity composition pressure-reducing filter, is widely used in chemical plant, pharmaceutical factory, petrochemical industry, the filtration under diminished pressure operation of R&D institution laboratory to solution.Now with bottle,suction, coordinate Buchner funnel to use, a suction filtration mouth that can be connected with vavuum pump is arranged at bottle,suction body side surface top.During suction filtration, the external vavuum pump of bottle,suction is bled under decompression, and liquid flows to filtrate bottle from Buchner funnel fast through filter paper.In the use procedure of existing bottle,suction, there is following problem: 1, filtrate is often inhaled into vavuum pump from suction filtration mouth, causes the pollution of vavuum pump; 2,, in suction filtration process, when power-off or the decompression of operate miss cut, in vavuum pump, circulation fluid cognition blows back into bottle,suction and causes suction filtration failure.
Utility model content
The utility model, for solving the technological deficiency of existing bottle,suction existence and the problem in use occurring, provides a kind of reverse-suction-proof suction filtration bottle.
For solving the problems of the technologies described above, the utility model scheme comprises:
A kind of Novel suction filter bottle, comprise bottleneck, bottle and suction filtration mouth, described bottle comprises inner bottle and external bottle, between described inner bottle and external bottle, form the passage of a U-shaped, described inside and outside bottle shares a bottleneck, on described inner bottle sidewall, is provided with passage, on described external bottle sidewall, be provided with suction filtration mouth, passage position is higher than suction filtration mouth, and the bottom of described external bottle sidewall arranges leakage fluid dram, the stopper shutoff of described leakage fluid dram.
Described stopper is rubber stopper or glass stopper.
The utility model provides a kind of Novel suction filter bottle, bottle consists of inner bottle and external bottle, between inner bottle and external bottle, form the passage of a U-shaped, when depressurized system work moves, use existing bottle,suction, filtrate may be inhaled into suction filtration mouth and be connected in vavuum pump, the utility model bottle,suction, can make filtrate enter U-shaped passage with passage, and prevent from entering the pollution that vavuum pump causes circulating fluid; When power-off or the decompression of operate miss cut, passage is higher than suction filtration mouth, and circulating fluid suck-back admission passage in vavuum pump, avoids mixing with filtrate, and the bottom of bottle side wall is provided with leakage fluid dram outside, and the liquid in passage can be discharged by leakage fluid dram.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Novel suction filter bottle of the utility model.
The specific embodiment
The utility model provides a kind of Novel suction filter bottle, below with reference to accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of Novel suction filter bottle, comprise bottleneck 1, bottle 2 and suction filtration mouth 4, bottle 2 consists of inner bottle 21 and external bottle 22, between inner bottle 21 and external bottle 22, form the passage of a U-shaped, inner bottle 21 and external bottle 22 share a bottleneck 1, inner bottle 21 side wall upper part arrange passage 3, external bottle 22 side wall upper part arrange suction filtration mouth 4, passage 3 is higher than suction filtration mouth 4, circulating fluid suck-back admission passage in vavuum pump, avoid mixing with filtrate, liquid in passage can be discharged by leakage fluid dram, external bottle 22 sidewall bottoms arrange leakage fluid dram 5, leakage fluid dram 5 is furnished with sealing plug 6.
Certain above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
Claims (2)
1. a Novel suction filter bottle, comprise bottleneck, bottle and suction filtration mouth, it is characterized in that: described bottle comprises inner bottle and external bottle, between described inner bottle and external bottle, form the passage of a U-shaped, described inside and outside bottle shares a bottleneck, on described inner bottle sidewall, is provided with passage, on described external bottle sidewall, be provided with suction filtration mouth, passage position is higher than suction filtration mouth, and the bottom of described external bottle sidewall arranges leakage fluid dram, the stopper shutoff of described leakage fluid dram.
2. a kind of Novel suction filter bottle according to claim 1, is characterized in that: described stopper is rubber stopper or glass stopper.
