Description

Technical Field

[0001] This utility model relates to the field of zinc isooctanoate synthesis technology, specifically to a zinc isooctanoate synthesis device. Background Technology

[0002] Zinc isooctanoate is an important organometallic compound. Its physical form is typically a pale yellow to brownish-red viscous liquid with a slight fatty acid odor. It is soluble in many organic solvents and is an amorphous liquid with good thermal stability. In the coatings industry, it is mainly used as a drying agent to accelerate the oxidative curing of paint films, especially suitable for white paints, reducing yellowing and improving paint transparency and durability. In the polymer materials field, it is mainly used as a catalyst in polyurethane elastomers and casting systems to optimize reaction efficiency; it also acts as a plastic stabilizer to inhibit resin thermal degradation.

[0003] The synthesis of zinc isooctanoate typically employs an ester exchange method. Isooctanoic acid and dichloromethane are added to a reaction vessel, and the temperature is raised to 50-60°C to completely dissolve the acid. Then, zinc salt is added and the mixture is stirred slowly at a constant temperature. After the reaction is complete, the solvent is recovered by vacuum distillation and unreacted solid impurities are removed by filtration to obtain crude liquid zinc isooctanoate. However, due to the slow stirring and the potential presence of agglomerates in the zinc salt, these agglomerates are difficult to fully integrate and participate in the reaction, resulting in waste. Therefore, we propose a new equipment for the synthesis of zinc isooctanoate. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a zinc isooctanoate synthesis device that screens the input zinc salt, and the zinc salt and solvent are more fully integrated, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a zinc isooctanoate synthesis device, comprising a mixing tank and a feeding mechanism; Mixing tank: Motor 2 is fixedly connected to the rear end of the upper surface of the end cap, and a stirring shaft is fixedly connected to the lower end of the output shaft of Motor 2. Heating plates are evenly distributed and fixedly connected to the outer arc surface of the mixing tank. The upper end of the end cap of the mixing tank is provided with evenly distributed mounting openings. Feeding mechanism: It includes a feeding seat, a screening component, a recovery pipe and a material bucket. The feeding seat is fixedly connected to the middle of the end cover of the mixing tank. The upper end of the feeding seat is connected to a cover plate by bolts. The lower end of the cover plate is equipped with a screening component. The material bucket is placed on the right side of the mixing tank. The upper end of the material bucket is fixedly connected to a recovery pipe. The discharge port on the right side of the feeding seat is located inside the upper end of the recovery pipe to screen the added zinc salt, so that the zinc salt and solvent can be more fully mixed.

[0006] Furthermore, it also includes a controller, which is located on the left side of the mixing tank. The input terminal of the controller is electrically connected to an external power source, and the output terminals of the heating plate and the second motor are both electrically connected to the output terminal of the controller to control the electrical appliances.

[0007] Furthermore, the screening component includes a screen, a support, a support column, a spring plate, and a spring. The screen is equipped with a support at both the left and right ends, and the upper end of the support is equipped with a support column symmetrically distributed front and back. The upper end of the support column passes through vertically adjacent round holes in the cover plate. The upper end of the support column is threaded with a spring plate, and the upper end of the support column is movably fitted with a spring. The spring is located between the cover plate and the vertically adjacent spring plate to achieve screening.

[0008] Furthermore, the screening component also includes a vibration motor and a motor base. The motor base is located in the middle of the filter screen, and the upper end of the filter screen is fixedly connected to the vibration motor. The input end of the vibration motor is electrically connected to the output end of the controller to drive the filter screen to vibrate.

[0009] Furthermore, the feeding mechanism also includes a motor and a dispersing shaft. The motor is fixedly connected to the lower end of the front side of the recovery pipe, and the dispersing shaft is fixedly connected to the rear end of the output shaft of the motor. The input end of the motor is electrically connected to the output end of the controller to disperse the clumps of zinc salt.

[0010] Furthermore, a temperature sensor is fixedly connected to the mounting port in the middle of the mixing tank end cap, and an online pH meter is fixedly connected to the mounting port at the rear end of the mixing tank end cap. The probes of the temperature sensor and the online pH meter are both located inside the mixing tank to detect the state of the mixed solution.

[0011] Furthermore, the outer arc surface of the feed seat is threaded with symmetrically distributed air inlets, which are evenly connected to an external air pump to facilitate the feeding of zinc salt.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This zinc isooctanoate synthesis equipment has the following advantages: The added zinc salts are vibrated and screened through the screen of the filter screen. Before returning to the material bucket from the recovery pipe, the clumps of zinc salts are broken up by the rotating dispersing shaft, making them easier to reuse. The zinc salts falling from the screen of the filter screen are all fine particles, which reduces the possibility of the clumps of zinc salts not being able to react completely, and makes the fusion more thorough.

The output shaft of motor 2 4 drives the stirring shaft 5 to rotate slowly to promote the fusion of isooctanoic acid and dichloromethane. At the same time, heating plate 6 heats the mixed solution of isooctanoic acid and dichloromethane. Temperature sensors 7 detect the temperature of the mixed solution and feed it back to controller 2. The average temperature of the two temperature sensors 7 is the temperature of the mixed solution. Feeding mechanism 3: It includes a feeding seat 31, a screening component 32, a recovery pipe 33, and a material bucket 36. The feeding seat 31 is fixedly connected to the middle of the end cover of the mixing tank 1. The upper end of the feeding seat 31 is bolted to a cover plate 10. The lower end of the cover plate 10 is provided with the screening component 32. The material bucket 36 is placed on the right side of the mixing tank 1. The upper end of the material bucket 36 is fixedly connected to the recovery pipe 33. The discharge port on the right side of the feeding seat 31 is located inside the upper end of the recovery pipe 33. The screening component 32 includes a filter screen 321, a bracket 324, a support column 325, a spring plate 326, and a spring 327. The left and right ends of the filter screen 321 are provided with brackets 324. The upper end of the support 324 is provided with symmetrically distributed support columns 325. The upper ends of the support columns 325 pass through vertically adjacent round holes in the cover plate 10. The upper ends of the support columns 325 are threadedly connected to spring plates 326. The upper ends of the support columns 325 are movably fitted with springs 327. The springs 327 are located between the cover plate 10 and the vertically adjacent spring plates 326. The screening assembly 32 also includes a vibrating motor 322 and a motor base 323. The motor base 323 is located in the middle of the filter screen 321. The upper end of the filter screen 321 is fixedly connected to the vibrating motor 322. The input end of the vibrating motor 322 is electrically connected to the output end of the controller 2. The feeding mechanism 3 also includes... The system includes a motor 34 and a dispersing shaft 35. The motor 34 is fixedly connected to the lower end of the front side of the recovery pipe 33. The dispersing shaft 35 is fixedly connected to the rear end of the output shaft of the motor 34. The input end of the motor 34 is electrically connected to the output end of the controller 2. The outer arc surface of the feeding seat 31 is threaded with symmetrically distributed air inlets 9. The air inlets 9 are evenly connected to an external air pump. The vacuum feeder sends the zinc salt in the material barrel 36 into the feeding tank. The zinc salt in the feeding tank falls into the interior of the filter screen 321. The vibration motor 322 starts, driving the filter screen 321 to vibrate. The spring 327 intensifies the vibration of the filter screen 321. (The spring 327 is removed after aging.) (26 can be replaced) The clumped zinc salt is filtered by the filter screen 321 and rolls down to the recovery pipe 33. The powdered zinc salt falls into the mixing tank 1 through the filter screen 321 to participate in the reaction. The external air pump delivers air through the air inlet 9, and the discharge port at the lower end of the discharge seat 31 forms a negative pressure environment to draw in the powdered zinc salt, preventing the zinc salt from staying too long inside the discharge seat 31. The clumped zinc salt falls from the recovery pipe 33. The output shaft of the motor 34 drives the dispersing shaft 35 to rotate, dispersing the clumped zinc salt and simultaneously causing the recovery pipe 33 to vibrate. The vibration of the recovery pipe 33 facilitates the falling of the clumped zinc salt. The dispersed zinc salt returns to the material tank 36 to avoid waste.

[0017] It also includes a controller 2, which is located on the left side of the mixing tank 1. The input end of the controller 2 is electrically connected to an external power source, and the output ends of the heating plate 6 and the motor 4 are both electrically connected to the output end of the controller 2.

[0018] The working principle of the zinc isooctanoate synthesis equipment provided by this utility model is as follows: The vacuum feeding tank is fixed to the feed port at the left end of the cover plate 10. Zinc salt is poured into the material tank 36. Isooctanoic acid and dichloromethane are conveyed through the installation port at the front end of the end cover of the stirring tank 1. After the feeding is completed, the controller 2 turns on the motor 4 and the heating plate 6. The output shaft of the motor 4 drives the stirring shaft 5 to rotate slowly to promote the fusion of isooctanoic acid and dichloromethane. At the same time, the heating plate 6 heats the mixed solution of isooctanoic acid and dichloromethane. The temperature sensor 7 detects the temperature of the mixed solution and feeds it back to the controller 2. The average temperature of the two temperature sensors 7 is the temperature of the mixed solution. When the temperature of the mixed solution reaches 50-60℃, zinc salt is added. The vacuum feeder sends the zinc salt in the material tank 36 into the feeding tank. The zinc salt in the feeding tank falls into the inside of the filter screen 321. The vibration motor 322 starts, driving the filter screen 321 to vibrate. The spring 327 intensifies the vibration of the filter screen 321. 27. After aging, the spring plate 326 can be removed and replaced. The clumps of zinc salt are filtered by the filter screen 321 and roll into the recovery pipe 33. The powdery zinc salt falls through the filter screen 321 into the stirring tank 1 to participate in the reaction. (During the reaction, the pH value of the mixed solution will rise as the acid is gradually consumed. Zinc salt is added gradually in 3-5 batches. When the average pH value detected by the online pH meter 8 is 6.5-7.0, no more is added. When the detected pH value is close to the value of complete reaction.) Afterwards, zinc salt is added in small amounts multiple times. An external air pump delivers air through the air inlet 9, creating a negative pressure environment at the discharge port at the lower end of the feeding seat 31. This draws in the powdered zinc salt, preventing it from lingering too long inside the feeding seat 31. The clumps of zinc salt fall through the recovery pipe 33. The output shaft of motor 34 drives the dispersing shaft 35 to rotate, dispersing the clumps of zinc salt and simultaneously causing the recovery pipe 33 to vibrate. The vibration of the recovery pipe 33 facilitates the falling of the clumps of zinc salt, which then returns to the material bucket 36, preventing waste.
