In order to solve the technical problem, the adjustable vacuum rapid sample filtering device of the utility model comprises a box body and a vacuum box, wherein the box body is connected in a sealing way, the vacuum box is formed by a cover plate, at least two mounting holes which are downwards communicated with the inside of the vacuum box are arranged above the cover plate, a connecting pipe is arranged inside the mounting holes and is connected with the mounting holes in a sealing way, a one-way valve is arranged above the connecting pipe in a sealing way, the one-way valve is provided with a funnel, at least two container fixing parts which are longitudinally corresponding to the positions of the mounting holes are arranged in the box body, a container is arranged on each container fixing part, the lower part of the connecting pipe is arranged,

and an air pump connected through a pipeline is arranged outside the box body.

As a preferred embodiment of the adjustable vacuum rapid sample filtering device of the utility model, the mounting hole fixedly connected with barometer of apron.

As a preferred embodiment of the adjustable vacuum rapid sample filtering device of the present invention, the end of the pipeline is provided with a check valve, and is fixedly connected with the box body through the check valve.

Advantageous effects

The utility model discloses the technique has following innovation advantage:

1. the utility model adopts vacuum filtration, which improves the filtration efficiency;

2. the whole vacuum pressure is mastered at any time by adopting the measurement of a barometer, so that the adjustment is convenient;

3. a one-way valve is added between the funnel and the connecting pipe to prevent backflow;

4. the one-way valve is additionally arranged between the air suction pump and the box body, so that the whole device can still maintain suction force as long as vacuum pressure exists in the box body even in a state that the air suction pump is closed, and the funnel can accelerate filtration.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1 to 5, the adjustable vacuum rapid sample filtering device of the present invention firstly provides a vacuum box, the vacuum box is composed of a box body 1 and a cover plate 2 in a sealing connection manner, at least two mounting holes 3 penetrating through the inside of the vacuum box main body downwards are arranged above the cover plate 2, the mounting holes 3 are circular, a connecting pipe 4 is installed in the mounting holes 3 through the mounting holes 3, the connecting pipe 4 is ensured to be in a sealing connection with the mounting holes 3, and a check valve 5 in the same sealing connection manner is arranged above the connecting pipe 4; in addition, the vacuum box also comprises a funnel 6, wherein the funnel 6 is arranged in the one-way valve 5, and the fluid in the funnel 6 directly enters the vacuum box after being filtered by the funnel 6 through the one-way valve 5; meanwhile, a barometer 10 fixedly connected with the cover plate 2 is also arranged above the cover plate, and the barometer 10 can be installed in the installation hole 3 or can be installed by independently arranging an installation position;

the box body 1 is also internally provided with at least two container fixing parts 7 which are longitudinally corresponding to the positions of the mounting holes 3, the container fixing parts 7 are annular grooves and can be in other shapes, the purpose is to place containers 8, and the number of the container fixing parts is equal to that of the mounting holes 8; the container 8 is arranged in the container fixing part 7, the container 8 is also positioned below the connecting pipe 4, the end part below the connecting pipe 4 is positioned in the container 8, and the funnel 6, the one-way valve 5, the connecting pipe 4, the container 8 and the container fixing part 7 are positioned in the same vertical straight line in sequence from top to bottom;

an air pump 9 connected through a pipeline 11 is arranged outside the box body 1, a one-way valve 5 is arranged at the end part of the pipeline 11, and the one-way valve 5 is fixedly connected with the box body 1.
