Description

Technical Field

[0001] The utility model relates to the technical field of solution concentration detection, in particular to a concentration detection device for a vehicle urea solution. Background Art

[0002] Automotive urea is an essential product for heavy-duty diesel vehicles to meet emission standards and is the key to reducing pollutant emissions from diesel vehicles. Automotive urea solution is generally composed of 32.5% high-purity urea and 67.5% deionized water. The concentration of automotive urea solution needs to be tested during its production process to ensure its subsequent normal use.

[0003] At present, when producing automotive urea, a sampling method is usually used to detect the concentration of automotive urea in a storage barrel. However, in the process of transporting automotive urea, pipeline transportation is required. The automotive urea in multiple storage barrels is collected in a main pipeline through small pipelines and supplied to the outside. This causes the concentration of automotive urea in different storage barrels to change after mixing with each other, and it cannot be monitored in real time. Utility Model Content

[0025] The effect achieved by the entire embodiment 1 is that when using the device, the filter cover 6 is fixed to one end of the butt joint pipe 2, and the filter cover 6 is extended to the inside of the main pipe 1, so that the solution inside the main pipe 1 can be introduced into the inside of the butt joint pipe 2 after being filtered by the filter cover 6, and then a support sleeve 13 is arranged on the filter cover 6. Through the support of the support sleeve 13, the support rod 8 can fix the waterproof motor 7, and the end cover 9 can be installed at the same time for connecting the concentration detection sensor 11. Since the concentration detection sensor 11 is inside the butt joint pipe 2, the solution concentration can be detected in real time when the solution flows.

[0026] Embodiment 2, as Figure 1-3As shown, a support sleeve 13 is fixed to the inner wall of one side of the filter cover 6, and a gap is left between the outer surface of the support sleeve 13 and the inner wall of the filter cover 6. A rotating shaft 4 is rotatably connected to one side of the filter cover 6, and two bent scrapers 5 are fixed to the outer surface of the rotating shaft 4. The two bent scrapers 5 are in contact with the outer surface of the filter cover 6, and one end of the two bent scrapers 5 extends to one side of the butt joint 2. An end cover 9 is arranged between the inner walls of the support sleeve 13, and a groove 10 is opened on one side of the end cover 9. A concentration detection sensor 11 is arranged inside the groove 10. A plurality of support rods 8 are fixed equidistantly along the circumferential direction between the inner walls of the support sleeve 13, and a waterproof motor 7 is fixed between one ends of the plurality of support rods 8.
