Embodiment 1

[0022] Such as figure 1 As shown, a kind of suction filtration bottle of the present invention has the vacuum filtration equipment of draining function, comprises suction filtration bottle 1, the suction filtration funnel 2 that cooperates suction filtration with suction filtration bottle 1, the connection between suction filtration funnel 2 and suction filtration bottle 1 The first cork 3 for inserting the lower end of the suction filter funnel 2 into the suction filter bottle 1 is arranged between, and the bottom of the suction filter bottle 1 is provided with a drain tank 6 with a top cover, and the suction filter bottle 1 is placed on the top cover of the drain tank 6 Above, the bottom of the suction filter bottle 1 is provided with a through hole 4 communicating with the inside of the drain tank 6, and the inside of the drain tank 6 is provided with a second cork 5 for blocking the through hole 4, and the second cork 5 is connected below the second cork 5. The pull rod 9 ...

Embodiment 2

[0025] Based on embodiment 1, the bottom of the drainage groove 6 is provided with a drainage hole 7, and the drainage hole 7 is concentric and coaxial with the through hole 4, and the inside of the drainage groove 6 is provided with a third cork 8 for blocking the drainage hole 7, and the third cork The stopper 8 is positioned at the bottom of the second cork 5, and the pull rod 9 passes through and fixes the third cork 8.

[0026] In the present invention, the third cork and the second cork are fixed on the same pull rod; when the suction filter bottle does not need to drain, the pull rod is pushed upwards, so that the second cork blocks the through hole of the suction filter bottle, and when necessary When draining, pull the pull rod downward, the through hole will be opened when the pull rod is downward, and the third cork will seal the drainage groove downward; after the liquid in the filter bottle is drained, push the pull rod upward, the second cork will re- Block the t...

Abstract

The invention discloses vacuum suction filtration equipment with a suction filtration bottle with a liquid draining function. The vacuum suction filtration equipment comprises the suction filtration body and a suction filtration funnel, wherein the suction filtration funnel is matched with the suction filtration bottle for suction filtration; a first soft wood cork is arranged between the suction filtration funnel and the suction filtration bottle, and is used for the lower end of the suction filtration funnel to be inserted into the suction filtration bottle; the lower part of the suction filtration bottle is provided with a water drain groove with an upper cover; the suction filtration bottle is arranged on the upper cover of the water drain groove; a through hole is formed in the bottom part of the suction filtration bottle and is communicated with the interior of the water drain groove; a second soft wood cork is arranged in the water drain groove and is used for blocking the through hole; the lower part of the second soft wood cork is connected with a pull rod, and the lower end of the pull rod penetrates through the bottom part of the water drain groove and reaches the exterior of the water drain groove. The vacuum suction filtration equipment has the advantages that by forming the through hole in the bottom part of the suction filtration bottle, filtrate in the suction filtration bottle can flow into the water drain groove in the lower part of the suction filtration bottle through the through hole; the filtrate can be drained without removing the suction filtration funnel, and the secondary installation of the suction filtration funnel is avoided.

Description

technical field [0001] The invention relates to a suction filtration device, in particular to a vacuum filtration equipment with a suction filtration bottle having a liquid drainage function. Background technique [0002] Vacuum filtration refers to the method of accelerating water filtration by using the negative pressure caused by air extraction. The shape of the suction filtration bottle is very similar to that of a conical flask, the difference is that there is a thin neck on the side, which is connected to a vacuum pump. When a funnel is placed on the mouth of the suction filter bottle to filter, the water flow pump (that is, the water flow suction pump) starts to pump air at this time, so that the air pressure in the suction filter bottle is reduced; if there is any solution in the filter paper on the funnel, Due to the effect of atmospheric pressure and gravity, these solutions will flow through the filter paper into the suction filter bottle below, and the residual s...
