Abstract
The utility model discloses a reverse-suction-proof suction filtration device, which belongs to the technical field of test equipment. An L-shaped extension tube is disposed at the connection position between an air exhaust tube of a filter flask and a flask wall, a perpendicular portion of the L-shaped extension tube is conical, and the top of the conical perpendicular portion is provided with an opening. A turn tube is disposed on the lower portion of a liquid downcomer of a funnel, and an outlet of the turn tube is adjacent to the flask wall of the filter flask. The funnel is a suction filtration funnel or a common funnel. A filter device is a sand filter device or porous filter device. An included angle between the turn tube and the liquid downcomer ranges from 95 degrees to 160 degrees. An opening of the L-shaped extension tube is positioned on the upper portion of the filter flask. The reverse-suction-proof suction filtration device is reasonable in design, simple in structure, easy in manufacture and high in applicability, reverse suction of liquid easy to foam during suction filtration is avoided effectively, operating efficiency is increased, and pollution of a vacuum pump is avoided.
Description
Technical field
The utility model belongs to the testing equipment technical field, is specifically related to a kind of suction filtration device that can prevent in foam or the filtrate suction vavuum pump.
Background technology
In the prior art, decompress filter claims 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, the equipment that the rate of filtration is accelerated.When in the chemical analysis method solution being filtered at present, the filter that is adopted is made of bottle,suction and funnel, and it is simple in structure.Because some solution easily produces a large amount of foams, this moment suction filtration liquid very easily when flowing down along the landing of bottle,suction wall, and near the air entry of bottle,suction, produce high negative, very easily, cause the pollution of solution loss and vavuum pump with in foam or the filtrate suction vavuum pump.In addition, because the height of exhaust tube inlet influences the actual capacity of bottle,suction in the middle and lower part of bottle,suction, reduced operating efficiency.
The utility model content
At the above-mentioned deficiency of prior art, the technical problems to be solved in the utility model provides a kind of anti-suck suction filtration device, and it can avoid the foam suction vavuum pump with filtrate or generation, and increase bottle,suction capacity, increase work efficiency.
The technical solution of the utility model is: anti-suck suction filtration device contains bottle,suction, funnel, is provided with filter in the funnel, funnel is the band grinding port plug, or is socketed with rubber stopper with holes.The exhaust tube of described bottle,suction is provided with L shaped prolongation pipe with the junction of bottle wall, and the vertical component of L shaped prolongation pipe is taper, and the top of taper is provided with opening; Liquid drop pipe bottom at funnel is provided with the corner pipe, the bottle wall of the contiguous bottle,suction of the outlet of corner pipe.Described funnel is suction funnel or common funnel.Described filter is sandbox filter or type filter with holes.Angle between described corner pipe and the liquid drop pipe is 95 degree～160 degree.The opening of described L shaped prolongation pipe is positioned at the top of bottle,suction.
The utility model is reasonable in design, and is simple in structure, makes easily, and adaptability is strong.Effectively avoid being easy to produce liquid suck-back in the suction filtration process of foam, improved operating efficiency, avoided the pollution of vavuum pump.
Description of drawings
Accompanying drawing 1 is the utility model one example structure schematic diagram.
Accompanying drawing acceptance of the bid keep the score state as follows: the 1-funnel; The 2-filter; 3-grinding port plug or rubber stopper with holes; 4-liquid drop pipe; The 5-bottleneck; 6-corner pipe; 7-bottle wall; The 8-bottle,suction; The 9-opening; The prolongation pipe of 10-L shape; The 11-exhaust tube.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.The utility model is a kind of foam suction vavuum pump that can avoid filtrate or its generation, and increases the capacity of bottle,suction, the suction filtration device of increasing work efficiency.Funnel 1 can be the suction funnel of band ground, also can be common funnel or other funnels.If common funnel can be regulated height by the rubber stopper of punching.Corner pipe 6 can be made in funnel 1 liquid drop pipe 4 bottoms, thus adherent needs can satisfy suction filtration the time.Suction filtration receiving bottle 5 is at 11 bottles of L shaped prolongation pipes 10 of inner connection of exhaust tube, and opening 9 is blow vents upwards, and L shaped prolongation pipe 10 dwindles internal diameter of the pipeline gradually, and the top is an opening 9, avoids sucking the foam of suction filtration liquid and generation thereof as far as possible.
Suction filtration device of the present utility model is mainly used in the suction filtration process in the scientific experiments such as chemical, medicine, biology, food.By redesign to the suction filtration device, adopting head is the diminishing L shaped prolongation pipe 10 of internal diameter of opening 9, increased the actual space that utilizes of suction filtration receiving bottle 8, and effectively avoided some to be easy to produce liquid suck-back suction filtration liquid or generation foam in the suction filtration process of foam, improved operating efficiency, avoided the pollution of vavuum pump, had simple in structure, characteristics such as it is easy to make, and adaptability is strong.
