To achieve these goals, the utility model provides a kind of withdrawal device, comprising: extracting part, and the inner chamber with variable volume, the bottom of extracting part is provided with the fluid passage that is communicated with inner chamber; Commutation portion, be connected with the fluid passage of extracting part, it also comprises suction pipe connecting end and the discharge tube connecting end that is interconnected, and is provided with first one-way valve in the suction pipe connecting end, be provided with second one-way valve in the discharge tube connecting end, first one-way valve and second one-way valve to open direction opposite; Suction pipe is connected with the suction pipe connecting end; Discharge tube is connected with the discharge tube connecting end.
Further, extracting part is a cylinder body, has the piston that can slide in cylinder body in the cylinder body, and piston is provided with the twitch bar.
Further, on suction pipe and/or discharge tube, flow control valve is installed.
Further, commutation portion is detachably connected on the fluid passage of extracting part.
Further, commutation portion and extracting part are structure as a whole.
Further, the suction pipe connecting end is provided with the discharge tube connecting end is vertical.
According to withdrawal device of the present utility model, employing has the extracting part of the inner chamber of variable volume, utilizing cavity volume to increase the generation negative pressure sucks liquid, the principle of drain is carried out the liquid cleaning operation of internal tank during the cavity volume compression, no longer adopt the mode of container being toppled over discharge opeing, solve the problem of Liquid extracting difficulty, shortened the liquid clearance time.
In addition, in the time need clearing up to the bigger container of volume, owing to do not need to move container, also just no longer need many people to fit into line operate, a people can independently finish whole scale removal process, and there is not the potential safety hazard that threatens operator's personal safety in the whole operation process, has reduced operator's work risk when having saved manpower, has effectively guaranteed operator's personal safety.
Description of drawings
The Figure of description that constitutes the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of withdrawal device of the present utility model.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
According to an embodiment of the present utility model, a kind of withdrawal device is provided, as shown in Figure 1, mainly comprise: extracting part 10, the inner chamber that has variable volume in the extracting part 10, and the bottom of extracting part 10 is provided with the fluid passage 11 that is communicated with inner chamber, preferably, extracting part 10 is a cylinder body, has the piston that can slide in cylinder body in this cylinder body, and piston is provided with twitches bar 13.
Like this, when cavity volume increased, liquid can be drawn in the inner chamber by fluid passage 11, and when cavity volume was compressed, liquid can be discharged from inner chamber by fluid passage 11 equally.
In Fig. 1, also show the commutation portion 30 that is connected with the fluid passage 11 of extracting part 10, commutation portion 30 comprises suction pipe connecting end 31 and the discharge tube connecting end 33 that is interconnected, be provided with first one-way valve 35 in the suction pipe connecting end 31, be provided with second one-way valve 37 in the discharge tube connecting end 33, first one-way valve 35 and second one-way valve 37 to open direction opposite, suction pipe 50 is installed on suction pipe connecting end 31, discharge tube 70 is installed on discharge tube connecting end 33.
Preferably, commutation portion 30 can removably be connected on the fluid passage 11 of extracting part 10, also can be structure as a whole with extracting part 10, to reach portable purpose.
And suction pipe connecting end 31 adopts vertical setting with discharge tube connecting end 33, makes suction pipe 50 and discharge tube 70 be easy to unfold like this, helps flowing of liquid.
And, can also play the effect of controlling liquid flow by flow control valve 90 is installed on suction pipe 50 and/or discharge tube 70.
The withdrawal device of present embodiment confirms at first whether suction pipe 50 and discharge tube 70 are connected correctly, and promptly suction pipe 50 should be connected with the suction pipe connecting end 31 that is provided with first one-way valve 35, and first one-way valve 35 is opened to extracting part 10 1 sides in use; Discharge tube 70 should be connected with the discharge tube connecting end 33 that is provided with second one-way valve 37, and second one-way valve 37 is opened to discharge tube 70 1 sides.
Subsequently suction pipe 50 is stretched in the container for clearance, discharge tube 70 is put into the container of contain fluid, bar 13 is twitched in pulling, the volume of extracting part 10 inner chambers is increased, liquid is sucked in the inner chamber of extracting part 10 through first one-way valve 35 by suction pipe 50, when the volume that promotes to twitch bar 13 compression extracting part 10 inner chambers, liquid will be discharged through fluid passage 11, because stopping of first one-way valve 35, liquid can only enter discharge tube connecting end 33, flow into discharge tube 70 through second one-way valve 37, flow at last in the container of contain fluid.Repeatable operation like this is up to the liquid in the container for clearance is discharged fully.
