Description

Technical Field

[0001] This utility model relates to a silicon meter assembly based on constant temperature control of sample water and ambient temperature compensation. Background Technology

[0002] In industrial water quality monitoring, silicon content is a key indicator. As the core device for detecting silicon content, the measurement accuracy of silicon meters is significantly affected by the temperature of the sample water and the ambient temperature. Traditional silicon meters have two major technical pain points: First, the sample water temperature is prone to fluctuations with operating conditions and seasons, deviating from the optimal measurement temperature of around 25°C, which leads to changes in chemical reaction rates and equilibrium states, causing detection deviations. Second, in low-temperature environments, excessively low ambient temperatures will affect the optical performance and signal stability of the photometer, the core component of the silicon meter. Furthermore, if the temperature difference between the sample water and the ambient temperature is too large, the silicon meter will stop measuring, causing monitoring interruptions. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a silicon meter assembly based on constant temperature control of sample water and ambient temperature compensation.

[0004] The above objectives are achieved through the following scheme: A photometer assembly based on constant temperature control of sample water and ambient temperature compensation includes a constant temperature device and a photometer body. The inlet of the constant temperature device's constant temperature pipe is connected to the sample water to be tested through a sample water pipe, and the outlet of the constant temperature device's constant temperature pipe is connected to the overflow cup of the photometer body through an inlet pipe. A heating jacket with constant temperature control is fitted around the photometer.

[0005] The aforementioned silicon metering unit based on constant temperature control of sample water and ambient temperature compensation includes a magnetic stirrer placed below the metering tank; the constant temperature controller includes a controller, which is connected to the constant temperature circuit, temperature sensor, heating element, and switch of heating jacket.

[0006] An overflow pipe is inserted into the bottom of the overflow cup. One end of the overflow pipe extends from the bottom surface of the overflow cup to the preset liquid level B inside the overflow cup, and the other end is connected to the drain connector.

[0007] The inlet pipe is equipped with a flow regulating valve, and the outlet pipe between the overflow cup and the metering tank is equipped with a solenoid valve.

[0008] The photometer has an exhaust channel at the top inside. One end of the exhaust channel is connected to the first air tube, and the other end is bent downwards and connected to the middle of the infusion channel below.

[0009] One end of the infusion channel is connected to the wall below the preset liquid level of the metering tank A, and the other end is connected to the first drain pipe. The other end of the first drain pipe passes through the bubble detector and is connected to the drain connector.

[0010] The reagent supply device includes four reagent bottles, a six-channel valve, and a peristaltic pump. Each reagent bottle is connected to a reagent tube and a reagent level detector. One end of the reagent tube is inserted into the reagent bottle, and the other end is connected to different input ports of the six-channel valve. The output port of the six-channel valve is connected to one end of the peristaltic pump tube, and the other end of the peristaltic pump tube passes through the peristaltic pump and is connected to one side of the bottom of the metering tank. Beneficial effects

[0011] 1. This utility model, by setting a constant temperature control device, can heat or cool the sample water entering the main body of the silicon meter, and stably control the sample water temperature within a suitable measurement range of about 25°C, so as to prevent the chemical reaction rate and equilibrium state of the sample water and reagent from changing due to temperature, reduce measurement deviation, and ensure the accuracy of measurement results.

[0012] 2. This utility model uses a heating jacket around the photometer. When the ambient temperature is too low in low-temperature environments such as winter, the heating jacket can keep the ambient temperature around the photometer constant at 35°C, reducing the temperature difference between the sample water and the environment, and avoiding the situation where the photometer stops measuring due to excessive temperature difference.

[0014] A silicon meter assembly based on constant temperature control of sample water and ambient temperature compensation includes a constant temperature device 3 and a silicon meter body 1. The inlet 33 of the constant temperature pipe 6 of the constant temperature device is connected to the sample water to be tested through the sample water pipe 7. The outlet 34 of the constant temperature pipe of the constant temperature device is connected to the silicon meter body through the inlet pipe 31, and a temperature sensor 32 is attached to the left end of the outlet of the constant temperature pipe. The main body of the silicon meter includes an overflow cup 30, which receives sample water treated by a constant temperature device through an inlet pipe and is connected to one side of the bottom of a metering tank 14 through an outlet pipe 13. The other side of the bottom of the metering tank is connected to a reagent supply device 2 through a peristaltic pump pipe 36. The metering tank is inside the photometer 15.

[0015] The photometer is surrounded by a heating jacket 16.

[0016] The heating jacket 16 is connected to the controller 4. The controller is connected to the constant temperature device and the temperature sensor via cables 5. The controller is used to control the temperature regulation of the constant temperature device and the switching on and off of the heating jacket.

[0017] The constant temperature device is used to heat or cool the sample water entering the silicon meter body, so that the temperature of the sample water 35 is stably controlled at 25℃±1℃. The temperature sensor is used to monitor the sample water temperature of the constant temperature device in real time and transmit the temperature data to the controller. The controller adjusts the heating or cooling of the constant temperature device according to the temperature data to ensure that the sample water temperature is controlled at 25℃±1℃. The heating jacket is used to heat the photometer when the ambient temperature is too low, and to stably control the ambient temperature around the photometer at 35℃±1℃. A magnetic stirrer 18 is placed below the metering tank to ensure that the reagent and sample water react fully.

[0018] An overflow pipe 21 is inserted into the bottom of the overflow cup. One end of the overflow pipe extends from the bottom surface of the overflow cup to the preset liquid level B inside the overflow cup, and the other end is connected to the drain connector 20 to drain the sample water in the overflow cup that exceeds the preset liquid level B 12, so as to prevent the sample water from overflowing.

[0019] The inlet pipe is equipped with a flow regulating valve 8 for adjusting the flow rate of sample water entering the overflow cup, and the outlet pipe between the overflow cup and the metering tank is equipped with a solenoid valve 9 for controlling the opening and closing of the outlet pipe.

[0020] Adjust the flow regulating valve so that a small amount of sample water always flows into the drain connector through the overflow pipe, ensuring that there is sufficient sample water in the measuring tank of the photometer.

[0021] The photometer has an exhaust channel 37 located at the top inside. One end of the exhaust channel is connected to the first air tube 10, and the other end is bent downwards and connected to the middle of the infusion channel 38 below.

[0022] One end of the infusion channel is connected to the wall below the preset liquid level 11 of the metering tank A, and the other end is connected to the first drain pipe 17. The other end of the first drain pipe passes through the bubble detector 19 and is connected to the drain connector. The bubble detector is located between the photometer and the drain connector.

[0023] If no measurement occurs, the sample water in the photometer will pass through the infusion channel, where it will mix with the air passing through the exhaust channel to form bubble water, which will then enter the first drain pipe. After the bubble detector checks whether the sample water is normal, it will enter the drain connector.

[0024] The reagent supply device includes four reagent bottles 29, a six-channel valve 24, and a peristaltic pump 23. Each reagent bottle is connected to a reagent tube 27 and a reagent level detector 28. One end of the reagent tube is inserted into the reagent bottle, and the other end is connected to different input ports 25 of the six-channel valve. The output port 26 of the six-channel valve is connected to one end of the peristaltic pump tube, and the other end of the peristaltic pump tube passes through the peristaltic pump and communicates with one side of the bottom of the metering tank. The reagent supply device is used to accurately deliver the corresponding reagent from the reagent bottle to the metering tank and mix it with the sample water. The peristaltic pump is used to control the flow rate of the input reagent; The reagent level detector is used to detect the reagent level in the corresponding reagent bottle in real time.

[0025] One of the input ports of the six-channel valve is connected to a drain connector via a second air pipe 22.

[0026] The second air tube is used to store air into the six-channel valve, and then the air pushes the reagent stored in the six-channel valve into the metering tank.

[0027] The heating jacket has a ring-shaped structure with an internal resistance wire and an external insulation layer.

[0028] You can choose the constant temperature device with model number DHC-05-A.

[0029] Working principle

[0030] When this utility model is working, the water sample to be tested first enters the constant temperature device through the water sample pipe. The constant temperature device stabilizes the water sample temperature at 25℃±1℃. The treated water sample enters the overflow cup through the inlet pipe and the flow regulating valve. The flow regulating valve is adjusted so that a small amount of water sample can always flow into the drain connector through the overflow pipe, so that the water sample in the metering tank is sufficient.

[0031] If no measurement occurs, the sample water in the metering tank will pass through the infusion channel at the top of the photometer, where it will mix with the air passing through the exhaust channel. It will then pass through the first drain pipe, be measured by the bubble detector, and then enter the drain outlet to check whether the sample water meets the standard. If it does, the measurement can be performed.

[0032] The peristaltic pump draws in a fixed amount of reagent each time it rotates. After the fixed amount of reagent is drawn out of the reagent tank, the six-channel valve switches to the second air tube, drawing air into the tubing. The air pushes the reagent into the photometer, thus completely separating it from other reagents.

[0033] The sample water enters the photometer through the overflow cup. When a measurement cycle begins: the solenoid valve is activated, the inlet pipe is closed, and zero-point calibration begins.

[0034] Switch the six-channel valve to the reagent tube connected to reagent A39 and draw up reagent A; switch the six-channel valve to the reagent tube connected to reagent B40 and draw up reagent B; switch the six-channel valve to the second air tube and draw in air, using air to push all the reagents into the photometer, and use a magnetic stirrer to mix the reagents, thus starting the first step of the reaction.

[0035] Switch the six-channel valve to the reagent tube connected to reagent C41, draw up reagent C, switch the six-channel valve to the second air tube, draw in air, use air to push all the reagents into the photometer, use a magnetic stirrer to mix the reagents, and the second step of the reaction begins.

[0036] Switch the six-channel valve to the reagent tube connected to reagent D42, draw up reagent D, switch the six-channel valve to the second air tube, draw in air, use air to push all the reagents into the photometer, use a magnetic stirrer to mix the reagents, and the second step of the reaction begins.

[0037] After the three reactions are completed, the photometer performs optical detection on the reaction liquid in the internal metering tank to obtain the silicon content-related signal and transmits it to the controller. When the ambient temperature is too low, the heating jacket around the photometer is controlled by the controller to stabilize the surrounding temperature at 35℃±1℃ to achieve temperature compensation.

[0038] After the measurement is completed, the solenoid valve will automatically open and start cleaning the photometer with sample water. The reaction solution inside the photometer will be discharged through the first drain pipe. After the inside of the photometer is cleaned, the six-channel valve will switch to the second air pipe, and the peristaltic pump will reverse until the reagent inlet pipe is full of sample water. Then the peristaltic pump will rotate forward until the reagent tube is emptied, and each reagent tube will be cleaned in turn.
