Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring, and in particular to an online detection device for resin exchange. Background Technology

[0002] Ion exchange resin technology is widely used in modern industrial production and water treatment. Ion exchange resins achieve separation, purification, and water softening by exchanging ions with those in solution. They play a crucial role in industries such as boiler feedwater treatment, chemical refining, and food and beverage processing. With the expansion of production scale and the increasing demands for product quality, monitoring the working status and performance of ion exchange resins has become particularly important. Traditionally, resin exchange processes typically employ offline testing, involving periodic sampling from the resin exchange system and sending it to a laboratory for analysis. This method has significant limitations: firstly, the long offline testing cycle makes it difficult to detect abnormalities during the resin exchange process, such as resin failure or contamination, potentially leading to fluctuations in product quality, equipment malfunctions, or even production interruptions; secondly, frequent sampling not only increases labor and time costs but also introduces errors that affect the accuracy of the test results.

[0003] Existing online detection devices for resin exchange involve mixing the introduced reagent with the exchanged solution before detection. However, in practical use, the reaction between the added reagent and the exchange solution requires a certain amount of time, and insufficient mixing can affect the detection results, leading to inaccurate detection. Therefore, we propose an online detection device for resin exchange. Utility Model Content

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An online detection device for resin exchange includes a reaction mechanism, a preparation mechanism fixedly connected to the rear side of the reaction mechanism, and a detection mechanism fixedly installed on the inner side of the inner end of the preparation mechanism.

[0007] The detection mechanism includes a motor housing, a rotating shaft movably mounted at the upper center of the motor housing, a stirring rod fixedly connected to the upper center of the rotating shaft, a stirring box fixedly connected to the upper end of the motor housing, a reagent port fixedly mounted at the upper center of the stirring box, a liquid inlet at the front center of the stirring box, a suction tube fixedly connected to the outer side of the stirring box, a suction pump fixedly connected to the end of the suction tube, an inlet tube connected to the end of the suction pump, and a detection box fixedly connected to the end of the inlet tube. By setting the stirring rod to stir the reagent and exchange solution, the reaction efficiency is improved, avoiding incomplete precipitation of target ions due to insufficient reaction between the reagent and solution during detection, thus improving the accuracy of detection during device use.

[0008] Furthermore, the preparation mechanism includes a preparation box, with support legs fixedly installed on the lower left and right sides of the preparation box.

[0009] Furthermore, the reaction mechanism includes a feeding box, a reaction box is fixedly installed at the lower end of the feeding box, a pump box is fixedly installed at the rear side of the reaction box, and an interface is provided at the end of the pump box. By setting the pump box to periodically and automatically draw the exchange liquid, the device can be automatically detected, which improves the convenience of using the device.

[0010] Furthermore, the front end of the suction tube has a curved structure, and the suction tube is sealed to the mixing tank. By setting the front end of the suction tube to a curved structure, the solution in the mixing tank can be completely sucked out for testing as much as possible, avoiding the residual solution from affecting the results of the next test.
