Description

Technical Field

[0001] This utility model relates to the field of surfactant detection technology, and in particular to a rapid surfactant detection device. Background Technology

[0002] Surfactants, also known as interfacial surfactants, are compounds that can significantly reduce the surface tension or interfacial tension between two liquids, between a liquid and a gas, or between a liquid and a solid. This property gives them their detergent and cleaning properties. Surfactants are widely used in detergents used in industrial washer-extractors. However, after washing, residual surfactants in the wastewater can affect water quality. Therefore, it is necessary to test for residual surfactants in the wastewater discharged from washer-extractors.

[0003] Traditional rapid surfactant detection devices are prone to errors due to the presence of solid particles or suspended matter in the wastewater, such as clothing fibers, dust, and dirt. These errors can affect the accuracy of the tests. Furthermore, most tests are performed only once, making it difficult to cross-verify the results.

[0004] A search of existing patents revealed a device for rapid detection of surfactant concentration in washing water (publication number: CN210720144U). This device features a composite bandpass filter consisting of quartz windows and a quartz substrate fixed to both sides of a through-channel. Based on multispectral (absorption, scattering, and fluorescence) fusion detection technology, the arrangement of the light source and multiple photodetectors ensures effective acquisition of transmission, scattering, and fluorescence / phosphorescence signals, enabling rapid detection of detergent residues in washing water, especially effective detection of low concentrations of surfactant residues. It effectively eliminates interference from liquid color and turbidity, significantly improving detection accuracy.

[0005] This rapid detection device for surfactant concentration in washing water is not convenient for simultaneous testing and comparison of multiple sets of data. A single test may result in inaccurate results due to factors such as solid impurities in the water, affecting the test results.

[0006] Therefore, it is necessary to invent a rapid surfactant detection device to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a rapid surfactant detection device to solve the problems mentioned in the background art, such as the inconvenience of simultaneously detecting and comparing multiple sets of data, and the possibility that a single detection may result in inaccurate results due to factors such as solid impurities in the water.

[0010] Preferably, the filtration mechanism includes a filter screen movably installed inside the filter box, and a rubber strip is fitted onto the inner top wall of the filter screen. The filter screen is used to filter solid impurities in wastewater.

[0011] Preferably, mounting holes are fixedly provided around the top surface of the filter screen, and mounting bolts are movably provided inside the mounting holes. A handle is fixedly installed in the middle of the top surface of the filter screen, which facilitates the removal of the filter screen by personnel.

[0012] Preferably, the detection mechanism includes a fluorescence sensor fixedly installed on the top surface of the detection box, a controller electrically connected to one side of the fluorescence sensor, and a display electrically connected to one side of the controller. Both the controller and the display are fixedly installed on the top of one side of the detection box. The fluorescence sensor detects surfactants in the wastewater and displays the results on the display via the controller.

[0013] Preferably, valve A is fixedly installed on the top of the surface of the inlet pipe, and valve B is fixedly installed on the top of the surface of the outlet pipe. Valve B is used to control the flow of the outlet pipe.

[0014] Preferably, a drain hose is fixedly provided at one end of the delivery pipe, and the sealing connection mechanism is connected to the drain pipe of the external washer-extractor, and the sealing connection mechanism seals the connection between the drain pipe of the external washer-extractor and the threaded pipe.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting up the filtration mechanism, the sealing rubber ring is put on the threaded pipe, and then the threaded pipe is connected to the external washer-extractor drain pipe. Open valve A, and the wastewater is transported to the filter box through the inlet pipe. Insert the filter screen into the filter box, and the filter screen will filter out the solid impurities in the wastewater, so as to avoid solid particles or suspended matter mixed in the washing water from affecting the detection of surfactants and reducing interference with the detection results.

[0017] 2. With the setup of three detection mechanisms, the filtered wastewater flows into the detection box, where the fluorescence sensor detects the surfactants in the wastewater. The controller controls the display to show the readings. The three detection mechanisms detect three different wastewater samples, allowing for cross-comparison and analysis, which improves the accuracy of the test results. Attached Figure Description
