Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a cymoxanil hydrochloride aqueous solution reaction vessel with negative pressure safety degassing function. Background Technology

[0002] Propamoate hydrochloride aqueous solution, as a highly efficient and low-toxicity broad-spectrum fungicide, is widely used in the field of crop disease control. Its production process typically involves chemical reactions such as hydrolysis and neutralization, requiring the completion of raw material mixing, reaction, and product stabilization processes in a reaction vessel. The negative pressure safety degassing reaction vessel combines a negative pressure environment with a safe degassing mechanism. Air is extracted from the reaction vessel using equipment such as a vacuum pump, creating a negative pressure environment inside the vessel lower than the external atmospheric pressure. Under negative pressure conditions, the boiling point of the liquid decreases significantly, and components that are not easily volatile under normal pressure vaporize more easily, thereby accelerating the escape of gases from the liquid and achieving efficient degassing.

[0003] For example, Chinese patent CN213611382U discloses a negative pressure-resistant liner-lined reactor, which includes a reactor body with an inner liner fixedly connected to it. A compression buffer layer is provided on the side of the inner liner away from the reactor body. The device includes a pressure gauge for real-time monitoring of the internal pressure of the reactor, a compression buffer layer for protecting the inner liner, and an air pump and extraction pipe for evacuating or filling the reactor to maintain pressure balance and prevent damage due to excessive pressure or negative pressure.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the stirring and pressure detection in the device can play a certain role in preventing liquid from boiling over and play a certain role in safe degassing, but when the liquid is heated, the gas in the liquid will escape and form bubbles. As the bubbles float upward, they may mix into gas masses, causing the liquid to churn violently and boil over in the reaction vessel, resulting in the liquid spraying out. Utility Model Content

[0005] The technical problem to be solved by this invention is that the existing technology has the disadvantage that the bubbles generated when the liquid is heated can cause the liquid to boil violently, thus affecting the safe degassing. To this end, we propose a cymoxanil hydrochloride aqueous solution reaction vessel with negative pressure safe degassing function.

[0006] To achieve the above objectives, this application adopts the following technical solution: a cymoxanil hydrochloride aqueous solution reaction vessel with negative pressure safety degassing function, comprising a tank body, wherein a rotating shaft is provided in the inner cavity of the tank body, and a plurality of slide rails arranged in a circular array are fixedly connected to the side wall of the rotating shaft near the upper end, the slide rails being located on the upper side of the inner cavity of the tank body, a slider is slidably connected to each slide rail, and a rotating plate is fixedly connected to the side of each slider away from the rotating shaft, and a plurality of horizontally arranged needles are fixedly connected to the facing surfaces of two adjacent rotating plates, the needles being used to puncture bubbles floating on the liquid surface, a plurality of vertically arranged partition plates are fixedly sleeved in the middle of the rotating shaft, each partition plate having a plurality of dividing holes, the upper end of the rotating shaft being rotatably connected to the middle of the top of the tank body and extending to the outside, and a motor being fixedly connected to the top of the tank body, the motor shaft being fixedly connected to the upper end face of the rotating shaft.

[0007] Preferably, a plurality of stirring blades are fixedly connected to the side wall of the rotating shaft near its lower end, and the stirring blades are used to stir the liquid in the tank.

[0008] Preferably, an air pump is fixedly connected to the top of the tank, and the air inlet of the air pump extends through to the top of the inner cavity of the tank. The air pump is used to draw the inside of the tank into a negative pressure state.

[0009] Preferably, float plates are fixedly connected to the bottom of both sides of the rotating plate, and the float plates are used to make the rotating plate float on the liquid surface and not sink.

[0010] Preferably, a feed pipe is fixedly connected to one side of the top of the tank, and a discharge pipe is fixedly connected to one side of the bottom of the tank. Valves are installed on both the feed pipe and the discharge pipe, which are used to inject materials into the reactor and discharge materials, respectively.

[0011] Preferably, a pressure gauge is fixedly connected to the outer wall of the tank, and the detection end of the pressure gauge extends into the inner cavity of the tank. The pressure gauge is used to test the pressure inside the tank.

[0012] Preferably, the upper end of the rotating shaft is fixedly sleeved with two connecting plates arranged vertically opposite each other, and the two ends of the slide rail are respectively fixedly connected to the opposing surfaces of the two connecting plates. The connecting plates are used to prevent the slider from moving up and down too much and falling off from both ends of the slide rail.

[0013] The technical effects and advantages of this utility model are as follows: In this invention, multiple partition plates divide the interior of the tank into multiple spaces. On the one hand, the partition plates can block the gas mass and prevent it from condensing into a large mass. On the other hand, they can also reduce the impact of the gas mass boiling on the liquid in other spaces, effectively reducing the situation where bubbles cause the liquid to boil.

[0014] In this invention, the needle can rotate with the rotating shaft. The rotation of the needle will puncture the bubbles and air masses that float to the surface of the liquid, thereby preventing the bubbles from continuing to expand and further preventing the liquid from boiling violently due to bubbles.

[0017] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0018] Reference Figure 1-5As shown, this utility model provides a technical solution: a cymoxanil hydrochloride aqueous solution reaction vessel with negative pressure safety degassing function, including a tank body 1. A rotating shaft 2 is provided in the inner cavity of the tank body 1. Several slide rails 3 arranged in a ring array are fixedly connected to the side wall of the rotating shaft 2 near the upper end. The slide rails 3 are located on the upper side of the inner cavity of the tank body 1. A slider 4 is slidably connected to each slide rail 3. A rotating plate 5 is fixedly connected to the side of each slider 4 away from the rotating shaft 2. Several horizontally arranged needles 6 are fixedly connected to the facing surfaces of two adjacent rotating plates 5. The needles 6 are used to puncture bubbles floating on the liquid surface. Several vertically arranged partition plates 7 are fixedly sleeved in the middle of the rotating shaft 2. Several partition plates 7 are provided with several dividing holes 8. The upper end of the rotating shaft 2 is rotatably connected to the middle of the top of the tank body 1 and extends to the outside. A motor 9 is fixedly connected to the top of the tank body 1. The shaft of the motor 9 is fixedly connected to the upper end face of the rotating shaft 2.

[0019] Several stirring blades 10 are fixedly connected to the side wall of the rotating shaft 2 near the lower end. The stirring blades 10 are used to stir the liquid in the tank 1. The rotation of the stirring blades 10 will slowly stir the liquid, making the liquid flow in the tank 1, thereby improving the uniformity of the liquid heating and playing a certain role in preventing the liquid from boiling over.

[0020] An air pump 11 is fixedly connected to the top of the tank body 1. The air inlet of the air pump 11 extends to the top of the inner cavity of the tank body 1. The air pump 11 is used to draw the inside of the tank body 1 into a negative pressure state. After the material is added into the tank body 1, the air pump 11 can draw the inside of the tank body 1 into a negative pressure state.

[0021] Both sides of the rotating plate 5 are fixedly connected to the bottom of the float plate 12. The float plate 12 is used to make the rotating plate 5 float on the liquid surface and not sink. The density of the float plate 12 is less than the density of the liquid in the material. The float plate 12 floats in the liquid, so that the rotating plate 5 will not sink completely into the liquid. The rotating plate 5 can rise and fall with the height of the liquid surface, so that the rotating plate 5 always stays at the position of the liquid surface.

[0022] A feed pipe 13 is fixedly connected to one side of the top of the tank body 1, and a discharge pipe 14 is fixedly connected to one side of the bottom of the tank body 1. Valves 15 are installed on both the feed pipe 13 and the discharge pipe 14. The feed pipe 13 and the discharge pipe 14 are used to inject materials into the reactor and discharge materials, respectively. Materials are added to the tank body 1 through the feed pipe 13 and discharged from the tank body 1 through the discharge pipe 14. When both valves 15 are closed, the tank body 1 can remain sealed.

[0023] A pressure gauge 16 is fixedly connected to the outer wall of the tank 1. The detection end of the pressure gauge 16 extends into the inner cavity of the tank 1. The pressure gauge 16 is used to test the pressure inside the tank 1. The pressure gauge 16 detects the negative pressure value inside the tank 1 and displays the value through the dial on the pressure gauge 16.

[0024] Two connecting plates 17 are fixedly sleeved on the upper end of the rotating shaft 2 and arranged opposite each other. The two ends of the slide rail 3 are respectively fixedly connected to the opposing surfaces of the two connecting plates 17. The connecting plates 17 are used to prevent the slider 4 from moving up and down too much and falling off the two ends of the slide rail 3. When the liquid level is lower than the lower end of the slide rail 3 or higher than the upper end of the slide rail 3, the connecting plates 17 on the upper and lower sides can block the slider 4 and prevent the slider 4 from falling off the two ends of the slide rail 3.

[0025] Working principle: First, the material, cymoxanil hydrochloride aqueous solution, is added into tank 1 through feed pipe 13. After the addition is completed, valve 15 on feed pipe 13 is closed to keep tank 1 sealed. Then, air pump 11 is started to extract the air from tank 1, creating a negative pressure inside tank 1. The pressure inside tank 1 can be detected by pressure gauge 16. When heating the material in tank 1, motor 9 is started, driving rotating shaft 2 to rotate. Rotating shaft 2 drives stirring blade 10 to rotate, which slowly stirs the material in tank 1. The pressure detection and stirring of the material can play a certain role in preventing the material from boiling over. While the material is being heated, gas will escape from the liquid, and some of the gas will form small gas bubbles in the liquid. When small bubbles flow upwards, they mix to form gas clusters. Multiple partition plates 7 divide the interior of the tank 1 into multiple spaces. On the one hand, the partition plates 7 can block the gas clusters and prevent them from condensing into larger clusters. On the other hand, they can also reduce the impact of gas clusters boiling over on the liquid in other spaces, effectively reducing the situation where bubbles cause the liquid to boil. Some smaller gas clusters will be broken into small pieces and pass through the partition holes 8 and continue to move upwards until they float to the surface of the liquid. When the rotating shaft 2 rotates, it will also drive the slide rail 3 to rotate. The slide rail 3 will drive the slider 4, the rotating plate 5 and the needle 6 to rotate in sequence. The rotation of the needle 6 will puncture the bubbles and gas clusters that float to the surface of the liquid, thereby preventing the bubbles from continuing to expand and further preventing the liquid from boiling over due to bubbles.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
