Abstract
Preparation solution anti-gathered structure of the fuel cell in peristaltic pump opening-closing process, packing groove box, peristaltic pump and spray head including preparation solution, inlet suction port and three-way connection are fixedly connected on spray head, the input end of three-way connection is fixedly connected with feed liquor pipe fitting, perfusion tube is fixedly connected on feed liquor pipe fitting, perfusion tube is connected with packing groove box, and peristaltic pump is fixedly connected on perfusion tube；Liquid back pipe is fixedly connected in the bifurcations of the three-way connection, liquid back pipe is connected with packing groove box.This structure adds threeway on spray head, connects liquid back pipe, and the preparation solution water conservancy diversion that can originally accumulate in spray head is understood to the packing groove box of preparation solution using liquid back pipe；So as to eliminate the problem that preparation solution after spray head is closed accumulates in spray head.
Description
Technical field:
The utility model relates to the technical fields of fuel cell preparation facilities, wriggle more specifically to fuel cell
Pump the anti-gathered structure of preparation solution in opening-closing process.
Background technique:
Fuel cell is a kind of chemical devices for chemical energy possessed by fuel being directly changed into electric energy, also known as electrochemistry
Electric organ.It needs for preparation solution to be sprayed on carbon paper by spray head in fuel cell manufacture preparation process, the conveying one of preparation solution
As by peristaltic pump provide power；And in the actual production process, spray head is first closed, and peristaltic pump turns off, but the preparation of perfusion tube
Liquid can continue a period of time of wriggling, and preparation solution can accumulate in spray head；When the preparation solution meeting gathered in next spray head unlatching, spray head
It is whole to spray, influence spraying data；And the preparation solution of accumulation also be easy to cause the blocking of spray head.
Utility model content:
The purpose of the utility model is to solve the deficiencies of the prior art, and provides fuel cell and opened and closed with peristaltic pump
The anti-gathered structure of preparation solution in journey can eliminate the problem that preparation solution after spray head is closed accumulates in spray head.
Preparation solution anti-gathered structure of the fuel cell in peristaltic pump opening-closing process, it is packing groove box including preparation solution, compacted
Pump and spray head are moved, is fixedly connected with inlet suction port and three-way connection on spray head, the input end of three-way connection is fixedly connected with feed liquor
Pipe fitting is fixedly connected with perfusion tube on feed liquor pipe fitting, and perfusion tube is connected with packing groove box, and peristaltic pump is fixedly connected on defeated
In liquid pipe；Liquid back pipe is fixedly connected in the bifurcations of the three-way connection, liquid back pipe is connected with packing groove box.
Preferably, the three-way connection is in level, and the bifurcations on three-way connection are distributed in the upside of three-way connection.
Preferably, the liquid back pipe is located at the top of spray head.
Preferably, the caliber of the liquid back pipe is less than the caliber of perfusion tube.
The utility model has the beneficial effects that:
This structure adds threeway on spray head, connects liquid back pipe, the system that will can originally accumulate in spray head using liquid back pipe
The packing groove box of standby liquid water conservancy diversion meeting preparation solution；So as to eliminate the problem that preparation solution after spray head is closed accumulates in spray head.
Detailed description of the invention:
Fig. 1 is the easy structure schematic diagram of the utility model；
In figure: 1, packing groove box；2, perfusion tube；3, peristaltic pump；4, spray head；5, inlet suction port；6, feed liquor pipe fitting；7, three
Pass joint；8, liquid back pipe.
Specific embodiment:
Embodiment: as shown in Figure 1, preparation solution anti-gathered structure of the fuel cell in peristaltic pump opening-closing process, including system
For packing groove box 1, peristaltic pump 3 and the spray head 4 of liquid, inlet suction port 5 and three-way connection 7, three-way connection are fixedly connected on spray head 4
7 input end is fixedly connected with feed liquor pipe fitting 6, and perfusion tube 2, perfusion tube 2 and packing groove are fixedly connected on feed liquor pipe fitting 6
Box 1 is connected, and peristaltic pump 3 is fixedly connected on perfusion tube 2；Liquid is fixedly connected with back in the bifurcations of the three-way connection 7
Pipe 8, liquid back pipe 8 are connected with packing groove box 1.
Preferably, the three-way connection 7 is in level, and the bifurcations on three-way connection 7 are distributed in the upper of three-way connection 7
Side.
Preferably, the liquid back pipe 8 is located at the top of spray head 4.
Preferably, the caliber of the liquid back pipe 8 is less than the caliber of perfusion tube 2.
Working principle: the utility model is the anti-gathered structure of preparation solution in fuel cell peristaltic pump opening-closing process,
Technical point is to be mounted with that a three-way connection 7, three-way connection 7 connect the liquid back pipe of packing groove box 1 on spray head 4, thus
When spray head 4 is first closed, peristaltic pump 3 is turned off, and the preparation solution flowed in perfusion tube 2 to spray head 4 can be returned to by liquid back pipe 8
In packing groove box 1.
The embodiment is rather than limited the present invention the utility model is illustrated.Any this field
Technical staff can modify to the embodiment under the spirit and scope without prejudice to the utility model, therefore this is practical
Novel rights protection scope, should be as listed by the claim of the utility model.
