Abstract
The utility model discloses an extraction filtration device capable for filtering insoluble materials, which has the characteristic of high filter speed. The extraction filtration device comprises a hopper and a container at the bottom of the hopper, wherein the chamber of the hopper is communicated with the chamber of the container; and a sealing device is connected between the hopper and the container. Since the sealing device connected between the hopper and the container can seal the container with the hopper, when in use, the air in the container can be extracted via externally connecting other suction units to generate negative pressure in the container, therefore, when fluid flows from hopper into the container, under external atmosphere pressure, the fluid can quickly flow into the container, thereby completing extraction and filtration quickly. The extraction filtration device has simple structure and low cost, can be produced in 30RMB, and is suitable for the instrument filtering insoluble materials.
Description
Technical field
The utility model relates to a kind of chemical apparatuses, especially relates to a kind of suction filtration device that can filter insolubles.
Background technology
When measuring in the sample insolubles with chemical analysis method at present, the filtration unit that is adopted is to be made of a bottle,suction and a sand core funnel, and it is simple in structure.But owing to be directly sand core funnel to be put on the bottle,suction liquid is filtered, so, sealing between sand core funnel and the bottle,suction is relatively poor, make that the pressure of external container pressure and internal tank is suitable, so it is slower that the liquid in sand core funnel flows into the speed of bottle,suction, the suction filtration poor effect can not be finished a sample by suction filtration in one day sometimes; Certainly, also adopt more complicated apparatus, effect is fine, but the price comparison height, a covering device is at least more than 100 yuans.
The utility model content
Technical problem to be solved in the utility model provides a kind of suction filtration device that can rapidly liquid filtering be fallen.
The technical scheme that its technical matters that solves the utility model adopts is: the suction filtration device, and the container that comprises funnel and be arranged on funnel bottom, the cavity volume of funnel communicates with the cavity volume of container, is connected with packoff between funnel and container.
As the preferred version of technique scheme, described packoff adopts plunger, and an end of plunger is connected in the bottom opening of funnel, and the other end is connected in the open top of container, is provided with flow passage in plunger.
Further be in funnel, to be provided with filtration unit.
As the preferred version of such scheme, filtration unit adopts sand core filter.
Further be between the bottom of the top of plunger and filtration unit, to be provided with the liquid fluid space.
The beneficial effects of the utility model are: by at the packoff that is connected between funnel and the container, in use, owing to seal between container and the funnel, can adopt other external getter device that the air in the container is extracted out, make internal tank produce negative pressure, thus at liquid when funnel flows into container, under the externally atmospheric effect, liquid can flow in the container rapidly, thus the suction filtration process of finishing that can be very fast.It is simple in structure, and is with low cost, only needs 30 yuan cost to make, and promotes the use of above the instrument that is particluarly suitable for insolubles is filtered.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Be labeled as among the figure: funnel 1, container 2, packoff 3, flow passage 4, filtration unit 5, liquid fluid space 6.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, suction filtration device of the present utility model, the container 2 that comprises funnel 1 and be arranged on funnel 1 bottom, the cavity volume of funnel 1 communicates with the cavity volume of container 2, is connected with packoff 3 between funnel 1 and container 2.By the packoff 3 that is provided with, can make sealing between funnel 1 and the container 2, like this, can the air in the container 2 be extracted out at external getter device in funnel 1 and the passage that container 2 communicates, make the inner negative pressure that produce of container 2, thus at liquid when funnel 1 flows into container 2, under the externally atmospheric effect, liquid can flow in the container 2 rapidly, thus the suction filtration process of finishing that can be very fast.
In the above-described embodiment, described packoff 3 can be the form realization that O-ring seal is set in the funnel 1 and the junction of container 2, as optimal way, described packoff 3 adopts plunger, one end of plunger is connected in the bottom opening of funnel 1, the other end is connected in the open top of container 2, is provided with flow passage 4 in plunger.When operation, with the bottom that an end of plunger inserts funnel 1, the other end inserts the top of container 2, needs the liquid of suction filtration test sample to pour funnel 1 into, flow in the container 2 from flow passage 4.Flow passage 4 can be the through hole that directly is opened in the plunger, also can be after offering through hole, connects forms such as glass tube or rubber tube and realize in through hole.Connect funnel 1 and container 2 by plunger, sealing is reliable, and attended operation is convenient.
In order to improve the suction filtration quality, in funnel 1, be provided with filtration unit 5.Like this, the small-sized particle that is insoluble to liquid also can filter out by filtration unit 5, improves the accuracy of test sample.Filtration unit 5 can adopt filter plants such as filter screen, and is better for making filter effect, and as optimal way, filtration unit 5 adopts sand core filter.
In order to finish the suction filtration process sooner, between the bottom of the top of plunger and filtration unit 5, be provided with liquid fluid space 6.Like this, liquid can be from flow through rapidly flow passage 4 and flowing in the container 2 of liquid fluid space 6 after filtering through filtration unit 5, and the top that can avoid plunger is with after filtration unit 5 directly contacts, and its filter velocity is shortcoming slowly.So, when making, except that liquid fluid space 6 is set, flow passage 4 suitably can also be done greatly, accelerate the whole suction filtration process that needs to measure sample.
