Description

Technical Field

[0001] The invention relates to the technical field of solution dripping impact force detection, in particular to a device for real-time detection of solution dripping impact force. Background Art

[0002] The phenomenon of droplets impacting walls is widely present in daily life and industrial production, and has related applications in fields such as spray cooling, trace oil and gas lubrication, inkjet printing, and internal combustion engine cylinder combustion.

[0003] In specific industrial applications, such as spray cooling, coolant is atomized into microdroplets that then obliquely impact the workpiece surface. Continued impacts form a thin film on the surface, and the flow pattern at the gas-liquid interface during the entire droplet-to-wall impact process is complex. Therefore, an experimental setup is needed to study the entire process of droplet generation, impact, and film formation during droplet impact. This provides reliable experimental data for subsequent studies of the jet breakup, droplet formation, and droplet impact mechanisms.

[0004] The solution drop impact force in the prior art is not convenient for accurate detection operations and is greatly affected by external factors, such as liquid remaining on the detection panel or being unable to be discharged in the form of drops, as well as dust or shaking, which can affect the detection results.

[0005] When applying for the present invention, the applicant searched and found that a Chinese patent disclosed a "rotating jet droplet generation and collision experimental device" with the application number "202310262651.7". This patent mainly promotes the jet to break up in a short time in a rotating mode to generate a large number of droplets. The droplets cover a wide area, the film forming process is rapid, and the liquid film thickness is easy to measure, thereby improving the experimental efficiency and experimental accuracy. However, the structure is exposed to the outside as a whole, is greatly affected by the outside world, and is prone to errors. Therefore, according to the applicant's invention, a device that can detect the impact force of solution drops in real time was invented, which solves the problem that the liquid remains on the detection panel or cannot be discharged in the form of drops.

During use, the threaded rod 2 can be rotated by turning the knob 3, and after rotation, it can be threadedly matched with the threaded block 4 to realize the movement of the threaded position. By rotating and matching the two ends of the rotating rod 5, the top plate 6 can be lifted. At this time, the top plate 6 rises, and the telescopic sleeve 8 extends out of the detection box 1. The required detection height can be checked by the scale 9. The impact force results are different at different heights; at this time, the liquid can be circulated through the inkjet device, and then the liquid can be discharged in the form of drops through the dropper 28 through the downward high-speed flow of the liquid. At this time, the solution will impact the surface of the sensing plate 22 vertically downward, and achieve high-precision impact force through the high-precision pressure sensor 25. The detection operation, after the collision, the solution will pass through the arc setting of the induction plate 22, and the liquid will flow outward and fall into the inside of the inclined groove 14, and be discharged through the discharge pipe 11. Then, when there is still liquid residue on the surface of the induction plate 22, it can be driven by the drive motor 18 to rotate the turntable 17. After rotation, it can cooperate with the rotation of the two ends of the moving rod 16 to realize reciprocating motion of the moving block 19. During the movement, the slider and the slide groove 27 slide together to maintain the horizontal lateral position movement. At this time, when the moving block 19 extends, the bottom wiping cloth is fitted with the induction plate 22 to complete the wiping operation. After wiping, a heating wire 23 is provided inside the moving block 19, which can realize the heating of the wiping cloth to achieve a drying effect, which is convenient for recycling. After the use of the detection box 1 is completed, the conical cover 29 is sleeved on the inside of the funnel 7 to provide protection.
