Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a sodium carbonate dosing system. Background Technology

[0002] In industrial production processes, sodium carbonate dosing systems are common auxiliary equipment used to add sodium carbonate solution to specific process stages to achieve functions such as water quality adjustment and neutralization reactions. Currently, existing industrial sodium carbonate dosing systems typically use domestic water as the solvent. However, domestic water contains abundant hardness components such as calcium and magnesium ions, which can react with sodium carbonate to form insoluble carbonate precipitates. This results in a significant loss of the active ingredient in the chemical, greatly reducing the efficiency of chemical use and increasing the company's chemical costs.

[0003] Furthermore, during the drug preparation process, water vapor generated by factors such as solution evaporation accumulates at the discharge port, creating a high-humidity environment. This high-humidity environment easily causes the drug to absorb moisture and caking, clogging the discharge pipe during transport. This leads to equipment failure and frequent downtime for maintenance, severely impacting production continuity, increasing equipment maintenance costs, and reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a sodium carbonate dosing system to solve the above-mentioned technical problems.

[0005] This utility model provides a sodium carbonate dosing system, including a dosing tank, which is connected to a water supply device containing demineralized water. The dosing tank's discharge pipe is connected to a sewage tank, and a temperature control and heat tracing mechanism is installed on the discharge pipe.

[0006] Furthermore, the demineralized water storage tank and the dosing tank are connected by a demineralized water pipeline, and an inlet butterfly valve is installed on the demineralized water pipeline.

[0007] Furthermore, a water quality detector is installed inside the medicine dispensing tank.

[0008] Furthermore, one end of the feed pipe is connected to the dosing tank, and the other end is connected to the dosing port of the sewage tank.

[0009] Furthermore, a discharge valve is installed on the discharge pipe.

[0010] Furthermore, the temperature-controlled heat tracing mechanism includes a self-regulating heat tracing cable, which is installed on the feed pipe.

[0011] Furthermore, the self-regulating heating tape is spirally wound around the outer wall of the feed pipe.

[0012] Furthermore, it also includes a control system, through which the self-regulating heating cable is electrically connected to a power source.

[0013] Furthermore, a temperature detection device electrically connected to the control system is installed at the drug dispensing port.

[0014] This invention uses demineralized water instead of domestic water as a solvent for dispensing medicine, which solves the problem of loss of effective ingredients due to reaction with hardness components in domestic water. By setting up a temperature-controlled heating system to heat and dehumidify the feed pipe, the medicine is prevented from absorbing moisture and caking. This solves the problem of equipment blockage caused by high humidity in existing systems, effectively avoids equipment failure and frequent downtime for maintenance, and improves production efficiency.

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown:

[0025] A sodium carbonate dosing system includes a dosing tank 1, and a water quality detector 7 is installed inside the dosing tank 1.

[0026] The dosing tank 1 is connected to a water supply device containing demineralized water. In this embodiment, the water supply device is a demineralized water storage tank 2. The demineralized water storage tank 2 and the dosing tank 1 are connected through a demineralized water pipe 5. An inlet butterfly valve 6 is installed on the demineralized water pipe 5.

[0027] The feed pipe 3 of the medicine preparation tank 1 is connected to the sewage tank 4. One end of the feed pipe 3 is connected to the medicine preparation tank 1, and the other end is connected to the medicine inlet 8 of the sewage tank 4. A feed valve 9 is installed on the feed pipe 3.

[0028] A temperature-controlled heating mechanism is installed on the feed pipe 3. The temperature-controlled heating mechanism includes a self-regulating heating tape 10. The power of the self-regulating heating tape 10 is 45W / m. The self-regulating heating tape 10 is spirally wound around the outer wall of the feed pipe 3. When the ambient temperature is lower than the set value, it compensates for the heat loss by heating its own resistance and maintains the target temperature.

[0029] It also includes a control system. The self-limiting temperature tracing cable 10 is electrically connected to a power source through the control system, and a temperature sensor 11 electrically connected to the control system is installed at the drug dispensing port 8.

[0030] In this embodiment, the control system includes an independent temperature controller connected to a temperature sensor 11. The independent temperature controller receives the real-time signal from the temperature sensor 11, compares it with the set temperature value, and calculates the deviation value. The temperature sensor 11 is connected to a power supply, which is connected to the self-regulating heating tape 10 through a circuit breaker and a relay. The independent temperature controller is electrically connected to the relay.

[0031] Precise temperature control process:

[0032] 1. Initial state and parameter settings

[0033] The user sets the target temperature (60℃) through the independent temperature controller interface and configures the PID parameters (P=50%, I=10s, D=2s) in the independent temperature controller interface; the self-limiting heating tape 10 is in a cold state, with low resistance and high initial power.

[0034] 2. Temperature Acquisition and Signal Transmission

[0035] Temperature sensor 11 measures the temperature of feed pipe 3 in real time, and converts the resistance signal into a 4-20mA signal through a transmitter, which is then transmitted to the controller of the temperature controller.

[0036] 3. Controller Operations and Output

[0037] The temperature controller compares the measured temperature with the set temperature, calculates the deviation, and generates an output signal based on the PID algorithm.

[0038] 4. Self-regulating heating tape 10 Heating and power regulation

[0039] The self-limiting heat tracing cable 10 heats up after being powered on, and its power gradually decreases as the temperature rises.

[0040] The controller corrects the output in real time:

[0041] When the temperature approaches the set value (55℃), the controller reduces the output signal through the PID algorithm, the relay reduces the conduction time, and the average power of the self-limiting heating tape 10 decreases to avoid temperature overshoot.

[0042] When the temperature reaches the set value (60℃), the controller outputs a signal to maintain the power of the self-limiting heating cable 10 just enough to compensate for heat loss, thus achieving constant temperature control.

[0043] 5. Temperature stability and dynamic regulation

[0044] Steady-state phase: Sensor 11 continuously monitors the temperature, and the controller adjusts the output of the small PID controller to counteract the effects of changes in ambient temperature or equipment heat load.

[0045] Abnormal situation handling: If the temperature exceeds the set upper limit (65℃), the controller will immediately cut off the relay output, the heating cable 10 will stop heating, and an alarm will be triggered (audio and visual alarm or upper computer prompt).

[0046] Working Principle: The demineralized water storage tank 2 contains demineralized water treated by reverse osmosis (RO) membrane technology, removing hardness components such as calcium and magnesium ions. The hardness of the demineralized water is controlled below 10 mg / L. It then flows through the demineralized water pipeline 5 into the chemical mixing tank 1. An inlet butterfly valve 6 is installed on the demineralized water pipeline 5 to control the amount of demineralized water used. A water quality detector 7 is installed in the chemical mixing tank 1 to measure the hardness of the demineralized water. The demineralized water is thoroughly mixed with industrial sodium carbonate to form a solution. This solution flows through the feed pipe 3 into the chemical inlet 8 and then into the wastewater tank 4 to participate in the reaction. An intelligent temperature control and heating system is installed at the feed pipe 3 to control the temperature of the industrial sodium carbonate solution. A temperature sensor 11 is installed at the chemical inlet 8 to measure the solution temperature and maintain it at approximately 60°C, adjusting as needed.

[0047] This invention uses demineralized water instead of domestic water as the solvent for dispensing medicine, solving the problem of loss of effective ingredients due to reaction with hardness components in domestic water. By setting up a temperature-controlled heating system to heat and dehumidify the feed pipe, it prevents the medicine from absorbing moisture and caking, solving the problem of equipment blockage caused by high humidity in existing systems, effectively avoiding equipment failure and frequent downtime for maintenance, and improving production efficiency. Through the control system and self-limiting temperature characteristics, it accurately controls the temperature, avoids overheating of the self-limiting heating tape, and dynamically adjusts the power to avoid the "overheating" problem of traditional constant power heating tapes.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
