In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 to 3 show a front view of a liquid adding device according to an embodiment of the present disclosure, fig. 2 shows a left side view of the liquid adding device corresponding to fig. 1 according to the embodiment of the present disclosure, and fig. 3 shows a bottom view of the liquid adding device corresponding to fig. 1 according to the embodiment of the present disclosure. The number of the first side plate 1, the second side plate 2 and the polygonal flat plate 3 is two. The polygonal flat plate 3 may be formed by combining an isosceles trapezoid and a square flat plate, and the short side of the isosceles trapezoid is connected with one side of the square flat plate to form a funnel-shaped polygonal flat plate 3. First curb plate 1 links to each other on one side with second curb plate 2, and the another side of first curb plate 1 equals and is connected with the isosceles trapezoid's of the dull and stereotyped 3 of polygon waist limit, and the another side of second curb plate 2 equals and is connected with the length of the another side of the dull and stereotyped 3 square board of polygon. Thus, the two first side plates 1, the two second side plates 2 and the two polygonal flat plates 3 form a pipeline structure with a large square opening and a small square opening. In practical application, the small square opening is an inlet of fluid, and the large square opening is an outlet of fluid. In some embodiments, modified from the above embodiments, the shape of the first side plate 1 may also be an isosceles trapezoid, etc., and the structure with a small fluid inlet and a large fluid outlet is within the protection scope of the present disclosure.
A first baffle 4 is located between the two profiled plates 3, which first baffle 4 can be used on the one hand to divert the flow and on the other hand to change the direction of flow of the fluid. The number of the first baffle 4 may be plural, preferably even number. The even number of first baffle-plates 4 is preferably symmetrically arranged between the two polygonal flat plates 3. The specific number of the first baffle 4, the deflection angle, the installation position, the length and the like of the first baffle 4 can be adjusted according to the flowing condition of the fluid. The thickness of the first baffle 4 should be as thin as possible to reduce the resistance to the fluid. In the embodiment of the present disclosure, the number of the first baffle plates 4 is two. The two first baffles 4 form a splayed structure and are symmetrically arranged between the two polygonal flat plates 3. In order to reduce the speed of the fluid after the fluid is divided by the baffles 4, splayed structures are formed between the first baffles 4 and the adjacent first side plates 1 and between every two adjacent first baffles 4, the fluid enters from a small opening and exits from a large opening, and the flow speed is reduced. Therefore, the included angle of the two first baffles is smaller than the included angle of the two waists of the isosceles trapezoid in the polygonal flat plate 3.
The length that first baffle 4 and polygon flat board 3 are connected is less than the distance between two bases of the trapezoidal root of equal waist in the polygon flat board 3, also is that first baffle 4 installs in two first curb plates 1, two second curb plates 2 and two polygon flat boards 3 constitution have one big square opening and the open inside pipeline structure of little square. Of course, the length of the connection between the first baffle 4 and the polygonal flat plate 3 is not as long as possible, and may be determined according to the flow rate of the fluid, the density of the fluid, the pressure of the fluid, and the like in the actual process. The length of the first baffle 4 connected with the polygonal flat plate 3 in the embodiment of the disclosure is preferably 1/2-2/3 of the distance between two bottom edges of a middle waist trapezoid in the polygonal flat plate 3.
The installation angle of the first baffle 4 and the polygonal flat plate 3 is related to the installation state of the liquid adding device. When there are a plurality of first baffles 4, the included angles between the plurality of first baffles 4 and the polygonal flat plate 3 may be the same or different. Can be vertically installed or can be obliquely installed with the polygonal flat plate 3. In general, the angle between the first baffle 4 and the polygonal flat plate 3 is preferably greater than 15 ° and equal to or less than 90 °. In the disclosed embodiment, it is preferably 90 °, i.e. the first baffle 4 is perpendicular to the polygonal plate 3. In practical application, the angle between the first baffle 4 and the polygonal flat plate 3 can be adjusted according to the arrangement of the liquid adding device in the gas-phase liquid tank.
A second baffle 5 is arranged at the large square opening formed by the first side plate 1, the second side plate 2 and the polygonal flat plate 3. The installation angle of the second baffle 5 is also determined by the arrangement of the liquid adding device in the gas phase liquid tank. So that the fluid flowing out of the liquid adding device is tangent to the wall surface of the gas-phase liquid tank wall as much as possible. The included angle between the second baffle 5 and the polygonal flat plate 3 can not be too small, and the too small included angle causes too large resistance and more energy loss after the fluid flows out of the liquid adding device. The included angle between the second baffle 5 and the polygonal flat plate 3 is more than or equal to 135 degrees and less than 180 degrees. In the embodiment of the present disclosure, the angle between the second baffle 5 and the polygonal flat plate 3 is preferably 150 °.
In the assembling process, the first side plate 1, the second side plate 2 and the polygonal flat plate 3 can be assembled and welded. The first baffle 4 is inserted into the polygonal flat plate 3 and then welded, then is assembled and welded with the flared pipe 7, and finally is assembled and welded with the connecting pipe 6.
When the liquid filling device is used, the residual liquid nitrogen inlet pipe groups of the connecting pipes 6 are butt-welded, liquid nitrogen enters the connecting pipes 6 and then enters the flaring through the flaring pipe 7 during liquid filling, the flowing cross section is enlarged, the flow rate is reduced, the liquid nitrogen enters the flaring, the flow rate is reduced to be slow to flow, and vortex-shaped liquid filling is formed in a liquid filling area.
In summary, the present disclosure provides a liquid adding device, in which the flow rate of liquid nitrogen is reduced through a flaring structure during liquid filling, and a baffle is installed in the flaring structure to enable fluid to flow according to a set structure, so as to form vortex-shaped liquid filling, thereby preventing the liquid surface from boiling during liquid filling, and preventing the liquid surface from affecting the storage of frozen articles in a gas phase region.
