Description

Technical Field

[0001] The utility model relates to a measuring device, in particular to a surfactant constant force measuring device, belonging to the technical field of solution foam characteristic testing. Background Art

[0002] Surfactants are widely used in the fields of chemical industry, textile, etc. Pure liquid cannot form stable foam, but after adding certain surfactants, the surfactant solution can form stable foam. Foam characteristics are of great significance in the fields of daily chemical industry, environmental protection, chemical industry, etc. Foam characteristics include foaming performance and foam stability. Evaluating the foam characteristics of different surfactant solutions is of great significance for formulation research and guiding practical applications. At present, the stirring method is usually used to test the foam characteristics of surfactant solutions. The stirring method usually uses a crusher to stir the surfactant solution. The stirring method currently used cannot allow the outside air to fully enter the surfactant solution, resulting in less foaming of the surfactant solution, which is not conducive to observing the dynamic changes of the foam amount.

[0003] Chinese patent application number: CN202023228962.2 discloses a surfactant testing device. The surfactant testing device includes a workbench, a transparent container, a stirring rod and a driving mechanism; the transparent container is arranged on the workbench, and is used to hold the surfactant solution to be tested; one end of the stirring rod is inserted into the transparent container; the driving mechanism is arranged on the workbench, and is connected to the stirring rod to drive the stirring rod to rise and fall. The patent provides a surfactant testing device that allows external air to fully enter the surfactant solution to increase the amount of foam generated by the surfactant solution, thereby facilitating the observation of the dynamic changes in the amount of foam.

[0004] This patent drives the stirring rod to rise and fall through a driving mechanism, which can drive the stirring rod to stir up and down in a transparent container to generate foam. However, the surfactant solution cannot form bubbles quickly by only stirring up and down, and the surfactant solution produces little foam, which is not conducive to observing the dynamic changes of the foam amount. Therefore, we propose a surfactant constant force measurement device. Utility Model Content

The air pump 15 is provided with a Z-shaped tube 62, and a hollow tube 63 is rotatably connected to the inside of the Z-shaped tube 62. One end of the hollow tube 63 passes through the container 3 and extends to the outside of the container 3. An impeller 64 is fixedly connected to the outer wall of the hollow tube 63 and located inside the Z-shaped tube 62. The Z-shaped tube 62 is exhausted by the air pump 15. Under the action of the airflow, the impeller 64 drives the hollow tube 63 to rotate, and the hollow tube 63 drives the vertical block 12 to rotate, so as to achieve horizontal stirring of the surfactant in the container 3 and accelerate the bubble efficiency. A plurality of vertical blocks 12 are symmetrically fixedly connected to the outer wall of the hollow tube 63 and located inside the container 3.

[0024] In actual application, the container 3 can be a transparent measuring cylinder commonly used in laboratories, with clear scale marks on the cylinder wall, so that the user can directly read the height of the foam generated through the scale marks, and the amount of foam generated can be obtained by calculation.

The air pump 15 pumps air into the interior of the hose 61, and the hose 61 transports gas to the interior of the containing plate 5. Under the action of the gas, the containing plate 5 slides downward, and the downward sliding of the containing plate 5 drives the reciprocating mechanism 10 to rotate. When the gas inside the containing plate 5 reaches a certain air pressure, the pressure relief valve 7 releases the pressure, so that the gas inside the containing plate 5 can be discharged into the interior of the container 3, so that the gas can fully enter the surfactant solution to achieve rapid bubbling. When the gas inside the containing plate 5 decreases, under the action of buoyancy, the containing plate 5 can move upward to achieve reciprocating sliding of the containing plate 5.
