Abstract
The utility model provides a filtering flask and relates to a device for filtration in a chemical experiment process. The filtering flask structurally comprises a tapered flask body and an air bleeding through tube arranged at the neck of a flask opening. The filtering flask is characterized in that a fluid discharging tube with a valve is arranged on the side wall of the lower part of the filtering flask body. For the filtering flask provided by the utility model, as the fluid discharging through tube with the valve is arranged on the side wall of the lower part of the filtering flask body, excessive filtrate in the filtering flask can be discharged without pulling out a rubber plug and a hopper; when the filter can not be contained in the filtrating process, the solution in the filtrating flask can be discharged as long as the opening of an air bleeding device is closed and the valve is opened; and after the completion of discharging, the valve is closed, and the air bleeding device is started to implement filtration; and therefore, the filtering flask is time-saving and labor-saving, simple in structure and easy in operation.
Description
Technical field
A kind of filtering flask relates to the device that filters usefulness in a kind of chemical experiment process.
Background technology
In the chemical experiment research process, often use the separation that filtering flask carries out solid-liquid.Present used filtering flask substantially all is glass material, thin mouthful neck, and body is tapered, near thin mouthful of neck place one aspirating hole is being arranged.During use funnel is passed hole in the rubber stopper, and make the funnel eck stretch out rubber stopper, approximately half reaches the effect of sealing to 2/3rds then rubber stopper to be filled in the bottleneck of filtering flask.Bleeding point connects ejector pump or vavuum pump, the operation that can filter.The problem that this filtering flask exists is that in filter process, if solution amount is few, filtering flask can be contained lower filtered fluid, once just can finish filtration.If solution amount is large, when solution in the filtering flask is expired soon, must stop to filter, the rubber stopper that is inserted with funnel is pulled out, even after disconnecting the air extractor of bleeding point, the solution in the filtering flask to out, is refiltered behind the jockey again.
Summary of the invention
The purpose of this utility model is the deficiency that exists for above-mentioned prior art, and a kind of simple in structure, processing ease is provided, and does not extract the filtering flask that rubber stopper and funnel just can be discharged filtrate.
The purpose of this utility model is achieved through the following technical solutions.
A filtering flask, which structure comprises a conical bottle, and bottled neck has a mouth through the suction tube, characterized in that the bottles in the filter body on the lower side are equipped with a liquide discharge tube with valve .
A kind of filtering flask of the present utility model, it is characterized in that described discharging tube is by a horizontal tube that passes filtering flask bottle lower sides, be positioned at bottle with horizontal tube termination be connected as a single entity ground, reclinate broken pipe, be positioned at bottle outer, form be connected as a single entity ground, reclinate broken pipe, horizontal tube termination.
A kind of filtering flask of the present utility model on the lower sides of filtering flask bottle, is provided with a discharging tube with valve, not extracting rubber stopper and funnel just can emit filtrate unnecessary in the filtering flask, when filtered fluid can not load in filter process, as long as stop the air extractor mouth, valve open, just can realize the solution in the filtering flask is released, after discharging, again valve closing, start air extractor and filter, laborsavingly save time again simple in structure, processing ease.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A filtering flask, which structure includes a tapered mouth bottle neck 1 and bottled with a suction through the tube 2, characterized in that the bottles of the filter on the bottom side wall of the body are equipped with a liquid discharge tube 4 with valve 3.Described discharging tube is by a horizontal tube that passes filtering flask bottle lower sides, be positioned at bottle with horizontal tube termination be connected as a single entity ground, reclinate broken pipe, be positioned at bottle outer, form be connected as a single entity ground, reclinate broken pipe, horizontal tube termination.
During operation, funnel is passed hole in the rubber stopper, and make the funnel eck stretch out rubber stopper, approximately half reaches the effect of sealing to 2/3rds then rubber stopper to be filled in the bottleneck of filtering flask, bleeding point connects ejector pump or vavuum pump, the operation of filtering when solution in the filtering flask is expired soon, is opened discharge opeing siphunculus that the lower sides of filtering flask bottle is provided with valve, solution in the filtering flask emits, and just can proceed filter operation.
Claims (2)
