Description

Technical Field

[0001] The utility model relates to the technical field of defoamer testing, in particular to a defoamer testing device for detecting defoaming performance. Background Art

[0002] Defoamer is a substance that can reduce the surface tension of water, solution, suspension, etc., prevent the formation of foam, or reduce or eliminate the original foam. It is usually used in food, papermaking or washing industries. As a chemical substance that can effectively reduce the generation of foam, its performance detection is particularly important. However, the traditional defoamer performance detection method has problems such as cumbersome operation and inaccurate results, which cannot meet the needs of modern industrial production. In order to solve these problems, a new defoamer performance detection device came into being;

[0003] In a defoaming performance test device of a defoaming agent with the announcement number CN211528347U, a measuring cylinder is included, a material extraction pump is provided at the measuring cylinder, the material extraction pump is connected to a nozzle assembly through a pipeline, the nozzle assembly is supported above the measuring cylinder through a support, the nozzle assembly includes a rotating plate that can rotate relative to the support, a first nozzle and a second nozzle are connected to the rotating plate, a three-way valve is provided at the pipeline, the three-way valve is connected to the first nozzle and the second nozzle, and the second nozzle is a high-pressure nozzle. The testing device of the utility model has a simple structure and is easy to operate. It can switch between the foaming environments under normal pressure and high pressure, saving experimental equipment and space, and is suitable for laboratory detection. When the above-mentioned prior art is used, it mainly utilizes multiple nozzles to spray liquid under different normal pressure and high pressure states, and utilizes the bubble height to detect the defoaming ability of the defoaming agent. However, in actual use, full contact between the defoaming agent and the detection solution is a necessary condition. Even if the defoaming agent and the detection solution need to be fully integrated, a comprehensive detection can be performed. The above-mentioned prior art lacks corresponding full mixing and stirring. On the one hand, it will affect the accuracy of the defoaming agent detection, because the insufficient contact will not achieve a good detection effect. On the other hand, it will affect the detection efficiency of the device. Because there is no sufficient contact, the foam and the defoaming agent cannot be fully integrated, the defoaming efficiency is reduced, and the overall detection efficiency is reduced.
