Description

Technical Field

[0001] This application relates to the field of acidification reactor technology, and in particular to a continuous reaction energy-saving acidification reactor. Background Technology

[0002] Acidification refers to the process of adding acid to change a system from alkaline or neutral to acidic. It is a very important step in chemical production. Different acids and amounts of acid are selected according to the purpose of acidification. For example, to oxidize potassium iodide in sodium arsenate (Na3AsO4) solution, the solution must be acidified to a strong acid state using strong acid such as sulfuric acid or hydrochloric acid. This is because sodium arsenate only has strong oxidizing properties under strong acid conditions. Acidification is the process of adding hydrogen ions to the solution to lower the pH value, and the added acid will not react with the ions in the original solution.

[0003] A search revealed that patent document CN213348873U discloses a continuous reaction acidification reactor. The technical solution includes an acidification reactor body with an auxiliary mechanism extending outwards. The auxiliary mechanism includes a motor fixedly mounted on the top of the acidification reactor body. A square rod is fixedly connected to the motor via an output shaft. The square rod is positioned on the top of the acidification reactor body and extends into its interior. A sleeve is fitted around the square rod, and auxiliary components are located outside the sleeve. The beneficial effect is that the design of the auxiliary mechanism, along with the sleeve and reciprocating screw, allows for stirring of the material inside the acidification reactor body. Simultaneously, the first stirring rod moves downwards, preventing centrifugal forces from forming within the material and ensuring optimal acidification.

[0004] In practical use, it was found that existing acidification reactors cannot automatically feed and discharge materials after the reactants reach the reaction standard, resulting in discontinuous production and low production efficiency. Therefore, we proposed a continuous reaction energy-saving acidification reactor to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a continuous reaction energy-saving acidification kettle, which has the functions of automatic feeding and discharging, continuous reaction, and improved production efficiency.

A gear mechanism is provided between the first stirring shaft and the rotating shaft.

[0008] By adopting the above technical solution, and by setting up a first stirring mechanism, the first stirring shaft can drive the stirring rod to rotate, thereby stirring the incoming material through the stirring rod. This allows the material to begin mixing fully the moment it enters the reaction zone, promoting the rapid progress of the reaction.

[0009] A further configuration of this application is as follows: the second stirring mechanism includes a second stirring shaft and a blade, the same second stirring shaft is rotatably mounted on the left inner wall of the functional box and the right inner wall of the acidification kettle, the second stirring shaft is located between the partition and the discharge pipe, the blade is provided on the second stirring shaft, the blade is located inside the acidification kettle, and a second transmission mechanism is provided between the second stirring shaft and the rotating shaft.

[0010] By adopting the above technical solution and by setting a second stirring mechanism, the second stirring shaft can drive the blades to rotate, which can realize the stirring of the material in the lower part of the acidification kettle by the blades, and can ensure that the material in the entire reaction area is fully mixed, thereby improving the uniformity and efficiency of the reaction.

[0011] A further configuration of this application is as follows: the feeding mechanism includes a conveying shaft and a spiral blade, the conveying shaft is fixedly installed on the motor output shaft, the right end of the conveying shaft is rotatably connected to the inner wall of the right side of the conveying cylinder, the spiral blade is provided on the conveying shaft, the spiral blade is located inside the conveying cylinder, and a first transmission mechanism is provided between the conveying shaft and the rotating shaft.

[0013] A further feature of this application is that the gear mechanism includes two bevel gears, and bevel gears are fixedly sleeved on both the first stirring shaft and the right end of the rotating shaft. Both bevel gears are located above the partition plate and mesh with each other.

[0014] By adopting the above technical solution and by setting a gear mechanism, the rotating shaft can drive the first stirring shaft to rotate synchronously.

[0015] A further configuration of this application is as follows: the first transmission mechanism includes two first transmission wheels and a first transmission belt. The first transmission wheels are fixedly sleeved on both the conveying shaft and the rotating shaft. The first transmission wheels are located inside the functional box, and the same first transmission belt is sleeved on both first transmission wheels.

[0018] By adopting the above technical solution and by setting a second transmission mechanism, the rotating shaft can drive the second stirring shaft to rotate synchronously.

The controller is located on the front side of the functional box, the heating plate is located on the right side of the acidification kettle, and the temperature sensor is located at the bottom of the partition. The temperature sensor is located on the left side of the first stirring shaft, and the temperature sensor, the heating plate and the controller are electrically connected.

[0020] By adopting the above technical solution and setting up a heating mechanism, the temperature sensor can monitor the temperature inside the acidification kettle in real time and feed the temperature data back to the controller. The controller can accurately adjust the working state of the heating plate according to the preset temperature range. When the temperature is close to the upper limit, the heating power is reduced, and when it is close to the lower limit, the heating power is increased. This can avoid the overheating or cooling phenomenon that may occur in traditional heating methods, thereby achieving the goal of energy saving.

[0021] A further feature of this application is that a pressure sensor is provided at the bottom of the partition, the pressure sensor is located between the feed pipe and the first stirring shaft, and the pressure sensor, the discharge valve and the controller are electrically connected.

[0022] By adopting the above technical solution and installing a pressure sensor, the pressure changes inside the acidification reactor can be detected in real time.

At this time, the controller immediately controls the discharge valve to open for discharge and closes the feed valve at the same time. This can prevent more material from entering and further increasing the pressure, ensuring the safe operation of the equipment and avoiding dangers caused by excessive pressure.

[0024] By adopting the above technical solution and installing a liquid level sensor, the liquid level in the acidification reactor can be monitored in real time. When the liquid level is low, it indicates that the amount of material in the reactor is insufficient. The controller will close the discharge valve and start the feed valve, so that new material can enter the acidification reactor in a timely manner, maintain the continuous reaction, and achieve the purpose of ensuring the continuity and stability of production.

Through the cooperation of the second transmission wheel, the second transmission belt, the second stirring shaft and the blade, the rotating shaft can drive the blade to rotate synchronously, and the blade can stir the material in the lower part of the acidification kettle, thus ensuring that the material in the entire reaction area can be fully mixed, thereby improving the uniformity and efficiency of the reaction.

[0028] (3) Through the cooperation of the controller, air pressure sensor, liquid level sensor, feed valve and discharge valve, when the air pressure reaches the set threshold, it indicates that the reaction of the reactants has reached the standard. At this time, the controller immediately controls the discharge valve to open for discharge and closes the feed valve at the same time. This can prevent more material from entering and further increasing the air pressure, ensuring the safe operation of the equipment and avoiding the danger caused by excessive air pressure. When the liquid level is low, it indicates that the amount of material in the reactor is insufficient. The controller will close the discharge valve and start the feed valve, which can allow new material to enter the acidification reactor in time, maintain the continuous reaction, and achieve the purpose of ensuring the continuity and stability of production.
