Description

Technical Field

[0001] This utility model relates to the field of calcium peroxide concentration detection technology, specifically a calcium peroxide concentration detection device. Background Technology

[0002] The detection of calcium peroxide concentration usually refers to the detection of the concentration of hydrogen peroxide released by calcium peroxide in the solution, because calcium peroxide (CaO2) slowly dissolves in aqueous solution and releases hydrogen peroxide (H2O2) and calcium hydroxide. Directly measuring the concentration of dissolved CaO2 molecules is relatively difficult and uncommon. Therefore, most devices and methods indirectly reflect the concentration of effective "calcium peroxide" in the solution by measuring the concentration of released H2O2. Common measurement methods include titration, spectrophotometry, and electrochemical detection. Electrochemical sensors are used, and the sensor head typically includes a working electrode (such as a platinum, gold, or glassy carbon electrode), a counter electrode, and a reference electrode. When a specific voltage is applied to the working electrode, H2O2 undergoes oxidation or reduction reactions on the electrode surface. The magnitude of the current generated is proportional to the concentration of H2O2 in the solution. Electrochemical detectors are portable and convenient, suitable for rapid on-site detection. However, most electrochemical detectors are handheld and portable, making them susceptible to damage to the display screen and surrounding components when dropped, affecting their use. Furthermore, during detection, some water sources with high turbidity can easily contaminate the detector head, affecting its lifespan. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] This utility model provides a calcium peroxide concentration detection device, which is equipped with a protective pad. When the main body of the detector is accidentally dropped, the display screen will land on one side, and the protective pad will provide cushioning protection to prevent the display screen from directly hitting the ground and being damaged. When the water source being tested is turbid, the first and second filter cylinders are threaded onto the detection rod to protect the detection head and reduce impurities from contaminating the detection head.

[0028] Figures 1-6 The diagram shown is an overall structural schematic of one embodiment of the calcium peroxide concentration detection device of this utility model. Please refer to [link / reference]. Figures 1-6 The present embodiment of a calcium peroxide concentration detection device includes a detector body 1, a display screen 2 embedded on the front side of the detector body 1 near the top, a protective soft pad 3 on the front side of the detector body 1, the protective soft pad 3 being disposed outside the display screen 2, the detector body 1 being connected to a detection rod 8 via a connecting line 7, and a detection head 9 being disposed at the end of the detection rod 8.

[0029] Protective frames 5 are provided at each corner of the upper part of the detector body 1. Through holes 10 are opened on the side wall of the protective frame 5. A first screw 6 is inserted through the through hole 10. One end of the first screw 6 is threaded to the detector body 1.

[0030] When the main body 1 of the detector is accidentally dropped, the display screen 2 lands on one side. The protective pad 3 provides cushioning protection, preventing the display screen 2 from directly hitting the ground and being damaged. At the same time, the protective frame 5 further protects the main body 1 of the detector. The first screw 6 can be removed to facilitate the maintenance and replacement of the protective frame 5.

[0031] The detection rod 8 includes a first filter cartridge 801 and a second filter cartridge 804 threadedly connected to the outer ring of the detection rod 8. The second filter cartridge 804 is disposed inside the first filter cartridge 801. A first mounting groove 802 is provided on the right end of the first filter cartridge 801. A first mounting hole 803 is provided in the first mounting groove 802. An integrated 20μm stainless steel primary filter is installed in the first mounting groove 802 through an external first bolt in conjunction with the first mounting hole 803. A second mounting groove 805 is provided on the right end of the second filter cartridge 804. A second mounting hole 806 is provided in the second mounting groove 805. A 5μm filter membrane is installed in the second mounting groove 805 through a second external bolt in conjunction with the second mounting hole 806.

[0032] If necessary, the turbid water source needs to be filtered to avoid affecting the detection head 9. The second filter cartridge 804, equipped with a 5μm filter membrane, and the first filter cartridge 801, equipped with an integrated 20μm stainless steel pre-filter, are sequentially threaded onto the outer ring of the detection rod 8. The integrated 20μm stainless steel pre-filter provides initial filtration of the turbid water source and protects the 5μm filter membrane from larger impurities. The 5μm filter membrane is a positively charged nylon 66 membrane. Filtering the turbid water source prevents it from affecting the detection head 9 while simultaneously repelling Ca. 2+ Adsorption only traps particulate matter, reducing detection deviation caused by filtration. Both the 5μm filter membrane and the integrated 20μm stainless steel pre-filter are fixedly installed through an external frame.

[0033] A handle 4 is fixedly installed on the right side of the main body 1 of the detector. A rear cover 11 is installed on the rear side of the main body 1 of the detector. A second screw 12 is installed through the rear cover 11. One end of the second screw 12 is threaded to the main body 1 of the detector. A cleaning cylinder 13 is fixedly installed on the rear side of the rear cover 11 near the bottom. The rear cover 11 includes a winding rod 1101 fixedly installed on the rear side of the rear cover 11 near the top. A limit frame 1102 is fixedly installed on the rear side of the rear cover 11. The limit frame 1102 is located between the winding rod 1101 and the cleaning cylinder 13. A spring 1103 is fixedly installed on the inner wall of the limit frame 1102. A clamp 1104 is fixedly connected to the inner end of the spring 1103.

[0034] When the main body of the detector 1 is not in use during the detection process, the winding rod 1101 is used to temporarily wrap the connecting wire 7 around the winding rod 1101 for simple storage. The clamp 1104 compresses the spring 1103, and the thin middle part of the detection rod 8 passes through the limiting frames 1102 on both sides and is placed between the clamp 1104. When the clamp 1104 is released, the clamp 1104 is pushed by the spring 1103 to clamp and limit the detection rod 8.

[0035] The cleaning cylinder 13 includes an ultraviolet sterilization lamp 1301 installed on the inner wall of the cleaning cylinder 13. A blowpipe 1302 is fixedly installed on the inner wall of the cleaning cylinder 13. The blowpipe 1302 is located above the ultraviolet sterilization lamp 1301. The blowpipes 1302 are connected to each other through an air supply pipe 1303. The air supply pipe 1303 is connected to an external pipe and a connecting pipe 1304. The connecting pipe 1304 is connected to a micro air pump. The micro air pump is installed inside the main body 1 of the detector.

[0036] After the test is completed, the detection head 9 is sterilized and cleaned by the ultraviolet sterilization lamp 1301. At the same time, under the action of the micro air pump, connecting pipe 1304, external pipe and air supply pipe 1303, the gas is blown out through the blow pipe 1302 to further clean the detection head 9 and reduce the contamination of the detection head 9.

[0037] Combination Figures 1-6 The specific usage process of the calcium peroxide concentration detection device in this embodiment is as follows: The detection head 9 is inserted into the water source to be tested via the detection rod 8. The water source is tested through the detection head 9, and the test data is observed on the display screen 2. If necessary, the turbid water source needs to be filtered to avoid affecting the detection head 9. The second filter cartridge 804, equipped with a 5μm filter membrane, and the first filter cartridge 801, equipped with an integrated 20μm stainless steel pre-filter, are sequentially threaded onto the outer ring of the detection rod 8. The integrated 20μm stainless steel pre-filter provides initial filtration of the turbid water source and protects the 5μm filter membrane from larger impurities. The 5μm filter membrane is a positively charged nylon 66 membrane, which filters the turbid water source, avoids affecting the detection head 9, and simultaneously repels Ca. 2+The adsorption process only traps particulate matter, reducing detection deviations caused by filtration. The winding rod 1101 is used when the main body of the detector 1 is not in use during the detection process. The connecting wire 7 is temporarily wrapped around the winding rod 1101 for simple storage. The clamp 1104 compresses the spring 1103, and the thin middle part of the detection rod 8 passes through the limiting frames 1102 on both sides and is placed between the clamp 1104. The clamp 1104 is released, and the clamp 1104 is pushed by the spring 1103 to clamp and limit the detection rod 8. The detection head 9 is pushed into the cleaning cylinder 13. The detection head 9 is sterilized and cleaned by the ultraviolet sterilization lamp 1301. At the same time, the gas is blown out through the blow pipe 1302 by the micro air pump, connecting pipe 1304, external pipe and air supply pipe 1303 to further clean the detection head 9 and reduce the contamination of the detection head 9.
