Description

Technical Field

[0001] This utility model relates to the field of analyzer body technology, and in particular to a free alkali analyzer for degreasing tank liquid. Background Technology

[0002] The free alkali analyzer for degreasing bath is a professional instrument used to monitor the concentration of free alkali in degreasing bath, playing a key role in metal surface treatment and other related processes.

[0003] In the field of free alkali testing of degreasing tank solutions, traditional methods face numerous challenges. Manual testing based on the principle of acid-base neutralization titration has significant drawbacks. The entire testing process requires operators to manually add standard acid solution drop by drop using a burette, relying entirely on personal experience and feel for precise control of the liquid volume. Slight errors can lead to over- or under-addition, directly affecting the accuracy of the test results. The entire testing process involves multiple steps, including solution sampling, transfer, titration, and endpoint determination, which are cumbersome, time-consuming, and prone to external environmental influences and operator condition, resulting in significant differences in test results among different personnel. Furthermore, the complex composition of some degreasing tank solutions makes manual endpoint determination difficult, often leading to visual errors, further exacerbating the complexity and uncertainty of the test, and failing to meet the demands of efficient and precise production testing in modern industry. Therefore, we propose a free alkali analyzer for degreasing tank solutions to address the aforementioned problems. Utility Model Content

[0005] Therefore, the purpose of this invention is to provide a free alkali analyzer for degreasing tank solutions, which can solve the numerous challenges faced by traditional methods in the field of free alkali testing of degreasing tank solutions. Manual testing methods based on the principle of acid-base neutralization titration have significant drawbacks. Throughout the testing process, the operator must manually add standard acid solution drop by drop using a burette. Controlling the liquid volume relies entirely on personal experience and feel; slight errors can lead to over- or under-addition, directly affecting the accuracy of the test results. The entire testing process includes multiple steps such as solution sampling, transfer, titration, and endpoint determination, which are cumbersome, consuming a lot of time and energy. Furthermore, manual operation is easily affected by the external environment and the operator's condition, resulting in significant differences in test results among different personnel. At the same time, some degreasing tank solutions have complex compositions, making manual titration endpoint determination difficult and often leading to visual errors, further exacerbating the complexity and uncertainty of the test, making it difficult to meet the needs of modern industrial production testing for high efficiency and precision.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is in conjunction with the appendix Figures 1-4 This utility model will be described in further detail.

[0023] In this embodiment, to address the numerous challenges faced by traditional methods in the testing of free alkali in degreasing tank solutions, this invention provides a solution that addresses the inherent limitations of manual testing methods based on acid-base neutralization titration. The manual method requires operators to add standard acid solution drop by drop using a burette, relying entirely on personal experience and feel for precise control of the liquid volume. Even slight errors can lead to over- or under-addition, directly impacting the accuracy of the results. Furthermore, the entire testing process involves multiple steps, including solution sampling, transfer, titration, and endpoint determination, making it cumbersome and time-consuming. Manual operation is also susceptible to environmental factors and operator condition, resulting in significant differences in test results among different personnel. Additionally, the complex composition of some degreasing tank solutions makes endpoint determination difficult through manual titration, often leading to visual errors and further complicating the testing process. This invention addresses the challenge of meeting the demands of modern industrial production testing for high efficiency and precision. Therefore, this invention discloses a free alkali analyzer for degreasing tank solutions.

[0024] Includes a base 1, a mixing tank 2 is fixedly installed on the top of the base 1, and two sets of additive components are installed on the top of the mixing tank 2;

[0025] The added components include an inlet pipe 3, which is fixedly installed on the top of the base 1. An electric push rod 4 is fixedly installed on the top of the inlet pipe 3. A drive rod 5 is fixedly connected to the bottom output end of the electric push rod 4. The drive rod 5 extends into the interior of the inlet pipe 3. A sealing plate 6 is fixedly installed at the bottom of the drive rod 5. The top of the sealing plate 6 is attached to the bottom of the inlet pipe 3. The bottom of the inlet pipe 3 extends into the interior of the mixing tank 2. Two storage tanks 20 are fixedly installed on the top of the mixing tank 2. The two storage tanks 20 are connected to the adjacent inlet pipe 3 through a pump 22 and a hose 21.

[0026] Specifically, the inlet pipe 3 is used to store and transport standard acid solutions or other reagents required for testing. The electric actuator 4 precisely controls the raising and lowering of the drive rod 5, which in turn drives the sealing plate 6 to open and close the inlet pipe 3. When the electric actuator 4 receives a control signal, the drive rod 5 moves downward, causing the sealing plate 6 to detach from the bottom of the inlet pipe 3, allowing the reagent to flow into the stirring tank 2 through the inlet pipe 3. Conversely, the drive rod 5 moves upward, causing the sealing plate 6 to adhere to the bottom of the inlet pipe 3, blocking the flow of reagent. Compared with traditional manual titration, this electric control method can more accurately control the amount of reagent added and avoid errors caused by manual operation.

[0027] A motor 7 is fixedly installed on the top of the mixing tank 2. A drive shaft 8 is fixedly connected to the bottom output end of the motor 7. Multiple fixing blocks 9 are fixedly installed on the outside of the drive shaft 8 from top to bottom. Each fixing block 9 has a mixing component on both sides.

[0028] Specifically, motor 7 serves as the power source for stirring, and upon startup, it drives the stationary blocks 9 to rotate via drive shaft 8. Multiple stationary blocks 9, working in conjunction with the stirring assembly, enable omnidirectional stirring of liquids at different heights within the stirring tank 2, ensuring thorough mixing of the solution and reagents and preventing testing errors caused by uneven mixing. The stationary blocks 9 also increase the stability of the stirring assembly, making the stirring process more efficient.

[0029] The stirring assembly includes a connecting rod 10, which is fixedly disposed on the outside of the fixing block 9. Multiple stirring plates 11 are fixedly disposed on the upper and lower sides of the connecting rod 10. A scraper 12 is fixedly disposed on the end of the connecting rod 10 away from the drive shaft 8. The outer side of the scraper 12 is attached to the inner wall of the stirring drum.

[0030] Specifically, the connecting rod 10 connects the fixing block 9 to the stirring plate 11 and the scraper 12, providing support. The stirring plate 11 promotes the flow of liquid during rotation, accelerating the reaction speed between the tank liquid and the reagent; the scraper 12 is in close contact with the inner wall of the mixing tank 2, which can promptly scrape off the liquid adhering to the tank wall, preventing liquid residue from affecting the test results. It also helps to keep the inner wall of the mixing tank 2 clean and avoid the accumulation of impurities that interfere with the test.

[0031] A liquid outlet pipe 13 is fixedly installed at the bottom of the mixing tank 2. A three-way valve 14 is fixedly installed at the bottom of the liquid outlet pipe 13. A drain pipe 15 is fixedly installed on one side of the three-way valve 14, and a delivery pipe 16 is fixedly installed on the other side of the three-way valve 14.

[0032] Specifically: the outlet pipe 13 is used to discharge the liquid after the reaction in the mixing tank 2, and the three-way valve 14 serves as a diversion valve. The drain pipe 15 can discharge the waste liquid in the mixing tank 2 after the test is completed, which is convenient for cleaning and replacing the new tank liquid sample; the inlet pipe 16 is connected to the analyzer body 19 and is used to transport the reacted liquid to the analyzer body 19 for free alkali concentration detection. By controlling the rotation angle of the ball valve 17 in the three-way valve 14, the liquid flow direction can be switched.

[0033] A ball valve 17 is rotatably mounted inside the three-way valve 14, and an electric actuator 18 is fixedly mounted on the rear side of the three-way valve 14. The output end of the electric actuator 18 is fixedly connected to the rear side of the ball valve 17.

[0034] Specifically, the electric actuator 18 receives a control signal and drives the ball valve 17 to rotate within the three-way valve 14 via its output shaft. When the ball valve 17 rotates to a specific angle, it can ensure that the liquid in the mixing tank 2 flows only to the drain pipe 15 or the delivery pipe 16, or completely block the liquid flow. The electric actuator 18 can precisely control the rotation angle and speed of the ball valve 17, providing more stable control of the liquid flow direction compared to a manually operated ball valve 17, thus ensuring the accuracy and reliability of the liquid delivery process during testing.

[0035] The analyzer body 19 is fixedly installed on the top of the base 1, and the end of the infusion tube 16 away from the three-way valve 14 is fixedly connected to the outside of the analyzer body 19.

[0036] Specifically, the analyzer body 19 is the core detection component of the entire device, used to analyze the free alkali concentration of the liquid delivered from the infusion tube 16. It integrates a sophisticated detection sensor and data processing module, which can quickly and accurately obtain the free alkali concentration value and output the results through a display screen or communication interface, providing reliable detection data for operators.

[0037] The specific working principle is as follows: First, the degreasing tank sample to be tested is injected into the mixing tank 2. Then, the electric actuator 4 is activated, causing the standard acid solution in the inlet pipe 3 to be injected into the mixing tank 2 according to the set amount. During the injection process, the electric actuator 4 precisely controls the opening and closing of the sealing plate 6 to ensure the accuracy of the acid solution addition. Next, the motor 7 drives the drive shaft 8, the fixing block 9, and the stirring assembly to start working. The stirring plate 11 thoroughly stirs the tank liquid and the acid solution, while the scraper 12 simultaneously cleans the inner wall of the mixing tank 2, ensuring uniform mixing and no liquid residue. After the mixing reaction is complete, the electric actuator 18 drives the ball valve 17 in the three-way valve 14 to rotate, guiding the liquid to the delivery pipe 16, allowing the mixture to flow into the analyzer body 19 for free alkali concentration detection. The analyzer body 19 outputs the detection results. After the detection is completed, the ball valve 17 is rotated again to discharge the waste liquid in the mixing tank 2 through the drain pipe 15, and the mixing tank 2 is cleaned to prepare for the next test. The entire process is controlled electrically, replacing traditional manual operation, which reduces the impact of human factors, improves testing efficiency and accuracy, and effectively solves the problems existing in the traditional degreasing tank liquid free alkali testing method.
