Abstract

The utility model relates to a filtering device which solves the technical problems that the common funnel is inconvenient for feeding and accessing, and has low filtering speed and the like. In the design, a funnel neck is stably sealed and connected with an edgy interface by a rubber tube; a glass cap provided with a polished edge and having good air impermeability is used for covering a funnel port with a polished edge; an air vent on the glass cap provided with a polished edge is blocked by a plug with a single-way air valve which only allows air to enter the funnel by the air vent; a feeding hole on the glass cap provided with a polished edge is blocked by a single hole plug with a glass tube; one end of the glass tube extends into the funnel and is in contact with the edge of filter paper while the other end thereof is connected with an air intake tube of a material bottle; the single-way air valve can only input air into the material bottle by an air inflating ball with a rubber tube; a sand core is arranged between the filter paper and the wall of the funnel; the edge of a receiving container is connected with the lower end of the funnel neck; the whole funnel and the receiving container are fixed on an iron support stand. The design is convenient and has low cost and easy production.

Description

A kind of filter

Affiliated technical field

The utility model relates to the experimental provision field, especially tests the filter field.

Background technology

Present known funnel both hands when reinforced all occupied (hand-held glass bar drainage, another is held container), very inconvenience.The rate of filtration is slow simultaneously, has prolonged experimental period.If have the little or rarer solution of those particles of solute of device suction filtration of vavuum pump with Buchner funnel etc., will take out brokenly filter paper.Common funnel long-neck when access takies very large space, and bumps disconnected easily.So a kind of reinforced convenience of design, access facility are arranged, necessity of the funnel that the rate of filtration is fast.

Summary of the invention

In order to overcome the deficiency that it is inconvenient, that the rate of filtration is slow, access is inconvenient that common funnel feeds in raw material, the utility model provides a kind of external pressure that utilizes to make the reinforced funnel filter synchronous with filtration, has accelerated the rate of filtration.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of filter, this filter are to be connected by the rubber tube stabilize containment by the interface of filler neck with the band rib, and the grournd glass good with air-tightness is placed in the ground bell mouth.Be arranged in the stopper that pore that grournd glass covers is plugged with the band Non-return air valve, only allow air to enter funnel by pore.Be arranged in the single hole plug that charging hole that grournd glass covers is plugged with the band glass tube, this glass tube one end stretches in the funnel and the filter paper EDGE CONTACT, and the other end connects rubber catheter, and the rubber catheter other end links to each other with the discharge nozzle of bottle for material again.The ball of inflating of band rubber tube links to each other with the air inlet pipe of bottle for material.Non-return air valve can only be inflated in bottle for material with the ball of inflating of rubber tube.Core is between filter paper and hopper walls, to reduce the impact of pressure to the filter paper tip.The receiving vessel edge links to each other with the filler neck lower end, is used to receive filtrate.Whole funnel and receiving vessel are fixed on the iron stand.When filter liquide, open pore earlier, the ball of inflating of compressive zone rubber tube makes the liquid in the bottle for material enter funnel, when treating that liquid level reach a certain height in the funnel, the stopper of band Non-return air valve is filled in the pore, and the ball of inflating of compressive zone rubber tube begins to filter then.

The beneficial effects of the utility model: this funnel utilize external pressure make reinforced with filter synchronously, accelerated the rate of filtration, and filler neck can dismantle, make things convenient for access, simple in structure.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the schematic diagram of a kind of filter of the utility model.

Among the figure: 1. pore, 2. charging hole, 3. grournd glass lid, 4. ground bell mouth, 5. filter paper, 6. core, 7. filler neck, the 8. interface of band rib, 9. receiving vessel, 10. rubber catheter, 11. bottle for material, 12. Non-return air valves, 13. be with the ball of inflating of rubber tube, 14. iron stand, 15. discharge nozzles, 16. air inlet pipe.

The specific embodiment

In Fig. 1, filler neck 7 connects by the rubber tube stabilize containment with the interface 8 of band rib.The grournd glass lid 3 good with air-tightness is placed in the ground bell mouth 4.The pore 1 that is arranged on the grournd glass lid 3 is plugged with the stopper of being with Non-return air valve, only allows air to enter funnel by pore 1.The charging hole 2 that is arranged on the grournd glass lid 3 is plugged with the single hole plug of being with glass tube, and this glass tube one end stretches in the funnel and filter paper 5 EDGE CONTACT, and the other end connects rubber catheter 10, and rubber catheter 10 other ends link to each other with the discharge nozzle 15 of bottle for material 11 again.The ball 13 of inflating of band rubber tube links to each other with the air inlet pipe 16 of bottle for material 11.Non-return air valve 12 can only be inflated in bottle for material 11 with the ball 13 of inflating of rubber tube.Core 6 is between filter paper 5 and hopper walls, to reduce the impact of pressure to filter paper 5 tips.Receiving vessel 9 edges link to each other with filler neck 7 lower ends, are used to receive filtrate.Whole funnel and receiving vessel 9 are fixed on the iron stand 14.When filter liquide, open pore 1 earlier, the ball of inflating of compressive zone rubber tube 13 makes the liquid in the bottle for material 11 enter funnel, when treating that liquid level reach a certain height in the funnel, the stopper of band Non-return air valve is filled in the pore 1, and the ball 13 of inflating of compressive zone rubber tube begins to filter then.

Claims

1. filter is characterized in that: the design is connected by the rubber tube stabilize containment by the interface of filler neck with the band rib, is placed in the ground bell mouth with the good grournd glass of air-tightness; Be arranged in the stopper that pore that grournd glass covers is plugged with the band Non-return air valve; Be arranged in the single hole plug that charging hole that grournd glass covers is plugged with the band glass tube, this glass tube one end stretches in the funnel and the filter paper EDGE CONTACT, and the other end connects rubber catheter, and the rubber catheter other end links to each other with the discharge nozzle of bottle for material again; The ball of inflating of band rubber tube links to each other with the air inlet pipe of bottle for material; Core is between filter paper and hopper walls, and the receiving vessel edge links to each other with the filler neck lower end, and whole funnel and receiving vessel are fixed on the iron stand.
