Description

Technical Field

[0001] This invention belongs to the field of beryllium-containing solution hydrolysis reaction technology, and particularly relates to a hydrolysis reaction device for beryllium-containing solutions. Background Technology

[0002] The hydrolysis reaction of beryllium-containing solutions refers to the reaction between beryllium ions and water molecules when beryllium-containing compounds are dissolved in water, forming beryllium hydroxide precipitate or releasing hydrogen ions, which leads to a change in the acidity or alkalinity of the solution. This reaction is usually manifested as the interaction between beryllium ions and water molecules, making the solution weakly acidic or neutral.

[0003] Currently, in actual use, existing hydrolysis reaction devices for beryllium-containing solutions generate a large amount of irritating gas during the precipitation of beryllium hydroxide by adjusting the pH value of the beryllium-containing solution with an alkaline solution. This irritating gas can easily leak out, affecting workers and the operating environment. Furthermore, the pH value is not accurately controlled and has a large deviation, resulting in unstable industrial beryllium oxide products.

[0004] To address this problem, we propose a hydrolysis reaction apparatus containing beryllium solution. Utility Model Content

[0005] The purpose of this invention is to solve the problems of irritant gas leakage and inaccurate pH control in the prior art, and to propose a hydrolysis reaction device containing beryllium solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A hydrolysis reaction apparatus for a beryllium-containing solution includes a reaction cylinder. A storage tank is disposed on the outside of the reaction cylinder. Three pumps are fixedly connected to the upper surface of the storage tank. The input end of each pump passes through the storage tank and extends into its interior. The output end of each pump is fixedly connected to an inlet pipe. The end of each inlet pipe away from the pump is fixedly connected to the upper surface of the reaction cylinder. A flow meter and a one-way valve are fixedly connected to the outer surface of each inlet pipe. A variable frequency servo motor is disposed above the reaction cylinder, and an anchor-type stirrer is fixedly connected to the output end of the variable frequency servo motor. The anchor-type stirring shaft is rotatably connected to the inner wall of the reaction cylinder. A purification tank is fixedly connected to the outer surface of the reaction cylinder. An air pump is fixedly connected to the left side of the purification tank. The power input end of the air pump passes through the purification tank and extends into the interior of the purification tank. Filter plates are fixedly installed on the inner wall of the purification tank. Two activated carbon plates are fixedly installed on the inner wall of the purification tank. A multi-port suction pipe is fixedly connected to the upper surface of the purification tank. The end of the multi-port suction pipe away from the purification tank is fixedly connected to the inner wall of the reaction cylinder. A pH meter is fixedly installed on the inner wall of the reaction cylinder. A controller is fixedly connected to the outer surface of the storage tank.

[0007] Preferably, the bottom surface of the reaction cylinder is fixedly connected to three first support legs, and the bottom surface of each first support leg is fixedly connected to a first base.

[0008] Preferably, the bottom surface of the storage box is fixedly connected to four second support legs, and the bottom surface of each second support leg is fixedly connected to a second base.

[0009] Preferably, a sealing cap is movably hinged to the upper surface of the reaction cylinder, and a handle is fixedly connected to the upper surface of the sealing cap.

[0010] Preferably, the bottom surface of the reaction cylinder is fixedly connected to a discharge pipe, and the outer surface of the discharge pipe is fixedly connected to a valve.

[0011] Preferably, a stabilizing frame is fixedly connected to the outer surface of the variable frequency servo motor, the bottom surface of the stabilizing frame is fixedly connected to the upper surface of the reaction cylinder, and a thermometer is fixedly connected to the inner wall of the reaction cylinder.

[0012] Preferably, a sealed bearing is fixedly connected to the top end of the anchor-type stirring shaft, and the outer ring of the sealed bearing is fixedly connected to the inner wall of the reaction cylinder.

[0013] In summary, the technical effects and advantages of this utility model are as follows: 1. A closed-loop gas treatment system is formed by a purification chamber, an air pump, and a multi-port suction pipe. The multi-port suction pipe extends deep into the inner wall of the reaction cylinder to capture all irritating gases generated during the hydrolysis reaction, preventing gas leakage. After the air pump draws the gas into the purification chamber, impurities are initially filtered by the filter plate, and then harmful components are adsorbed by two layers of activated carbon plates, achieving efficient gas purification treatment. This not only protects the operating environment from pollution but also completely eliminates the harm of irritating gases to the health of workers. 2. By setting up a pH meter, the acidity change of the solution can be monitored in real time, and the data is fed back to the controller to form an intelligent control closed loop. The three liquid pumps on the storage tank, together with the flow meter and one-way valve, can accurately control the injection volume and injection speed of the material solution. By controlling the injection volume, the problem of large pH value deviation can be controlled, and the pH value control accuracy is greatly improved. The anchor-type stirring shaft driven by the variable frequency servo motor rotates smoothly, which can fully stir the solution in the reaction tank, increase the solution contact area, accelerate the reaction rate, and improve the uniformity of pH value.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5 A hydrolysis reaction apparatus for a beryllium-containing solution includes a reaction cylinder 1, a storage tank 2 disposed on the outside of the reaction cylinder 1, three pumps 11 fixedly connected to the upper surface of the storage tank 2, the power input end of each pump 11 passing through the storage tank 2 and extending into the interior of the storage tank 2, three first support legs 3 fixedly connected to the bottom surface of the reaction cylinder 1, and a first base 4 fixedly connected to the bottom surface of each first support leg 3. The first support legs 3 can effectively isolate and support the reaction cylinder 1 from the ground, and can prevent the reaction cylinder 1 from directly contacting the ground. The first base 4 increases the contact area with the ground.

[0018] Each pump 11 has a fixed inlet pipe 12 at its power output end. The end of each inlet pipe 12 away from the pump 11 is fixedly connected to the upper surface of the reaction cylinder 1. A flow meter 13 and a one-way valve 14 are fixedly connected to the outer surface of each inlet pipe 12. Four second support legs 5 are fixedly connected to the bottom surface of the storage tank 2. A second base 6 is fixedly connected to the bottom surface of each second support leg 5. The second support legs 5 can evenly distribute the weight of the storage tank 2 and the internal solution, and prevent the storage tank 2 from deforming at the bottom due to excessive local stress. The second base 6 further enhances the fit between the storage tank 2 and the ground, and prevents the storage tank 2 from shifting due to slight vibrations generated when the pump 11 is working.

[0019] A variable frequency servo motor 15 is installed above the reaction cylinder 1. The output end of the variable frequency servo motor 15 is fixedly connected to an anchor-type stirring shaft 22. The top end of the anchor-type stirring shaft 22 is rotatably connected to the inner wall of the reaction cylinder 1. A sealing cover 8 is movably hinged to the upper surface of the reaction cylinder 1. A handle 9 is fixedly connected to the upper surface of the sealing cover 8. The sealing cover 8 can seal the top of the reaction cylinder 1 during the hydrolysis reaction, further reducing the possibility of irritating gases escaping from the gaps at the top of the reaction cylinder 1. The handle 9 allows the operator to quickly open or close the sealing cover 8.

[0020] A purification chamber 7 is fixedly connected to the outer surface of the reaction cylinder 1. An air pump 17 is fixedly connected to the left side of the purification chamber 7. The power input end of the air pump 17 passes through the purification chamber 7 and extends into the interior of the purification chamber 7. A discharge pipe 24 is fixedly connected to the bottom surface of the reaction cylinder 1. A valve 25 is fixedly connected to the outer surface of the discharge pipe 24. The discharge pipe 24 provides a controllable channel for the discharge of beryllium hydroxide precipitate generated by the hydrolysis reaction. After the reaction is completed, the operator can open the valve 25 to allow the precipitate to be discharged smoothly along the discharge pipe 24.

[0021] A filter plate 18 is fixedly installed on the inner wall of the purification chamber 7, and two activated carbon plates 19 are also fixedly installed on the inner wall of the purification chamber 7. A multi-channel suction pipe 20 is fixedly connected to the upper surface of the purification chamber 7. A stabilizing frame 16 is fixedly connected to the outer surface of the variable frequency servo motor 15. The bottom surface of the stabilizing frame 16 is fixedly connected to the upper surface of the reaction cylinder 1. A thermometer 21 is fixedly connected to the inner wall of the reaction cylinder 1. The stabilizing frame 16 can provide stable support for the variable frequency servo motor 15. The variable frequency servo motor 15 will generate a certain vibration when it is working. The stabilizing frame 16 can effectively absorb the vibration. The thermometer 21 can monitor the temperature change of the solution in the reaction cylinder 1 in real time and feed the temperature data back to the operator. The operator can adjust the reaction conditions according to the temperature to avoid affecting the rate and effect of the beryllium hydroxide precipitation reaction due to excessively high or low temperature.

[0022] The end of the multi-port suction pipe 20 away from the purification box 7 is fixedly connected to the inner wall of the reaction cylinder 1. A pH meter 26 is fixedly installed on the inner wall of the reaction cylinder 1. A controller 10 is fixedly connected to the outer surface of the storage tank 2. A sealed bearing 23 is fixedly connected to the top of the anchor-type stirring shaft 22. The outer ring of the sealed bearing 23 is fixedly connected to the inner wall of the reaction cylinder 1. By using the sealed bearing 23, the solution and gas inside the reaction cylinder 1 can be effectively blocked from leaking through the gap between the anchor-type stirring shaft 22 and the inner wall of the reaction cylinder 1, thus preventing the leakage of irritating gases.

[0023] The working principle of this utility model is as follows: In use, the operator first connects the controller 10, pump 11, flow meter 13, frequency converter servo motor 15, air pump 17, thermometer 21, and pH meter 26 to an external power supply. Simultaneously, the flow meter 13, pH meter 26, and pump 11 are connected to the controller 10 for control. Then, the sealing cover 8 is opened to add the raw material into the reaction cylinder 1. Afterward, the sealing cover 8 is closed, and the pH meter 26 and controller 10 are turned on. Based on the data fed back by the pH meter 26, the controller 10 controls the pump 11 to start. The pump 11 draws the corresponding material solution from the storage tank 2. The storage tank 2 has three independent spaces that can store different solutions. The material solution enters the reaction cylinder 1 through the inlet pipe 12. The flow meter 13 monitors the injection volume of the material solution in real time and feeds the data back to the controller 10. When the injection volume reaches the set value, the controller 10 controls the pump 11 to stop working. The one-way valve 14 prevents odors and liquid from entering the reaction cylinder. The solution is reversed to ensure accurate injection volume. Then, the variable frequency servo motor 15 is started, driving the anchor-type stirring shaft 22 to rotate and fully stir the solution in the reaction chamber 1, ensuring thorough mixing and accelerating the reaction rate. The air pump 17 absorbs irritating gases after the reaction chamber 1 is opened, preventing gas leakage. The generated irritating gases are pumped into the purification chamber 7 by the air pump 17 through the multi-port suction pipe 20. The gas first passes through the filter plate 18 for preliminary filtration of impurities, and then passes through two layers of activated carbon plates 19 to adsorb harmful components, achieving efficient gas purification. Modified activated carbon can be used for the activated carbon plates 19 to improve the purification effect. The purified gas is discharged from the purification chamber 7, avoiding harm to the operating environment and the health of the staff. The thermometer 21 monitors the temperature change of the solution in the reaction chamber 1 in real time and feeds the temperature data back to the staff. The staff can adjust the reaction conditions according to the temperature. After the reaction is completed, the staff opens the valve 25 to allow the generated beryllium hydroxide precipitate to be discharged smoothly along the discharge pipe 24.
