DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] With reference to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present application is a detection device for performance detection of a foamed concrete foaming agent, comprising a cabinet 1, a fixed seat 2 is fixedly connected to one side of the cabinet 1, a detection tube 3 is arranged inside the fixed seat 2, a motor 4 is arranged on the top of the fixed seat 2, a rotating column 5 is fixedly connected to the output end of the motor 4, stirring rods 6 in annular array are fixedly connected to the outer wall of the rotating column 5, a scraping rod 7 is fixedly connected to one side of the stirring rod 6, the scraping rod 7 is in close contact with the inner wall of the detection tube 3 on one side, a cleaning plate 8 is fixedly connected to the bottom end of the scraping rod 7, a water inlet and outlet assembly is arranged inside the detection tube 3, the rotating column 5 is rotatably connected inside the detection tube 3, the water inlet and outlet assembly comprises a water discharge pipe 9, a water inlet 10 is arranged on the top of the water discharge pipe 9, and water valves are arranged on the water discharge pipe 9 and the water inlet 10;

[0031] Specifically, when detecting, first, the foaming agent to be detected is injected into the detection tube 3 through the water inlet 10; in order to ensure the accuracy of the detection of the foaming agent, the driving motor 4 is started to drive the rotating column 5 to rotate; with the rotation of the rotating column 5, the stirring rod 6 also rotates synchronously around the axis of the rotating column 5, so as to generate a stirring effect in the detection tube 3, so that the bubbles generated by the foaming agent are more delicate and uniform; such uniformly distributed bubbles can improve the stability of the detection and the reliability of the data; in order to prevent errors in detection, the same foaming agent is usually detected in multiple detection tubes 3 respectively, and finally the average value of multiple detection results is obtained to obtain more accurate detection data; in addition, in order to avoid the interference of residual liquid on the next detection result, clean water can be injected through the water inlet 10 before new detection; at this time, the driving motor 4 and the rotating column 5 drive the stirring rod 6 and the scraping rod 7, so that the scraping rod 7 scrapes the inner wall of the detection tube 3 to remove the attached residues; at the same time, the bottom cleaning plate 8 also performs cleaning operation; on the design, different density bristles are used on both sides of the cleaning plate 8 to adapt to the cleaning needs of the inner wall, so as to ensure that the residual foaming agent is completely removed; after cleaning, the clean water can be discharged into the laboratory waste water storage container through the water outlet 9, so as to avoid the pollution of waste liquid to the environment or the interference of waste liquid to the next experiment; this process not only ensures the cleaning of the detection tube 3 before each detection, but also effectively prevents cross contamination, so as to significantly improve the accuracy and reliability of the detection; through the above design, the system can maintain stability in multiple detections, ensure that each detection meets the standardization requirements, and provide accurate and reliable results for experiments.

[0032] With reference to Figure 1 and Figure 4 , the outer wall of the detection tube 3 is sleeved with a constant temperature tube 12, one end of the constant temperature tube 12 is fixedly connected with a water adding pipe 11 fixed in the fixed seat 2, the water adding pipe 11 is used to connect with the laboratory water pipe, and warm water or cold water can be injected into the constant temperature tube 12, a ventilation groove 13 is opened in the cabinet 1, the ventilation groove 13 is aligned with the constant temperature tube 12 in the same axis, a fan 15 is arranged in the cabinet 1, guide vanes 14 are arranged on both sides of the fan 15, and the fan 15 and the guide vanes 14 are arranged in the ventilation groove 13;

[0033] Specifically, in the detection process, in order to effectively control the exothermic effect caused by the reaction, and ensure that the system is maintained at a constant temperature to obtain accurate detection results, water at a predetermined temperature can be injected through the water injection pipe 11; the injected water will release or absorb heat in this area when passing through the constant temperature pipe 12, thereby maintaining the temperature around the detection tube 3 stable under the action of heat conduction; the constant temperature pipe 12 not only plays a role in heat conduction, but also continuously adjusts the temperature during system operation, ensuring that the detection environment is not affected by external temperature fluctuations; especially during the detection process, if a large amount of heat is generated due to chemical reactions or other factors, the system can inject low-temperature water through the constant temperature pipe 12 to quickly absorb excess heat; at the same time, the fan 15 guides the airflow through the air deflector 14 to blow cold air directly to the detection tube 3, further assisting in cooling, and ensuring that the temperature of the detection tube 3 rapidly decreases to a safe range; this design not only realizes temperature control of the detection system under high exothermic conditions, but also ensures constant reaction conditions, which helps to improve the accuracy and repeatability of the detection results; under such temperature control conditions, the system can effectively avoid errors caused by sudden temperature rises, thereby greatly improving the stability and reliability of the detection process.

[0034] Working principle: When detection is needed, the foaming agent to be detected is first injected into the detection tube 3 through the water inlet 10. At this time, in order to better detect the foaming agent, the driving motor 4 is needed to drive the rotating column 5 to rotate, and the stirring rod 6 will be driven to rotate around the rotating column 5 as the axis, so that the bubbles generated by the foaming agent in the detection tube 3 can be more dense and uniform, so as to better detect. At the same time, in order to prevent errors in detection, the same portion of the foaming agent will be detected in two detection tubes 3 to obtain the average value of the detection value. In order to prevent the residual liquid from interfering with the detection results of the next detection, clean water can be injected into the position of the water inlet 10 before the next detection, and the stirring rod 6 driven by the driving motor 4 and the rotating column 5 will drive the scraper 7 to scrape the inner wall of the detection tube 3, and the cleaning plate 8 at the bottom will also start to clean and brush, and the cleaning plates 8 on both sides are also provided with different density bristles to better clean and brush the residual agent. The clean water after cleaning can be discharged into the laboratory wastewater storage container through the water outlet 9 position as the foaming agent after detection. In order to prevent the heat release during detection and the need for constant temperature conditions, water at the required temperature can be injected through the water injection pipe 11, and the injected water will release and maintain heat at the constant temperature pipe 12 position, thereby ensuring the temperature of the detection tube 3 position. During the detection process, when a large amount of heat is released, cold water can be injected through the constant temperature pipe 12, and the fan 15 blows air through the air deflector 14 to cool the detection tube 3 position.

[0035] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
