Technical Field

[0001] This utility model belongs to the field of emulsification equipment technology, specifically relating to a methyl anthranilate emulsification device. Background Technology

[0002] Methyl anthranilate has a wide range of applications in many fields. In some applications, such as water-based coatings, water-based inks, and cosmetic emulsions, emulsification is necessary to ensure uniform dispersion in the aqueous phase, improving solubility and stability in aqueous environments, and facilitating processing and use. Current emulsification equipment for methyl anthranilate simply involves setting up a stirring and dispersing device within the emulsification tank, resulting in poor emulsification effects and impacting subsequent use. Utility Model Content

[0003] Therefore, it is necessary to provide an o-aminobenzoic acid methyl ester emulsification device to address the problems of the existing technology.

[0004] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows:

[0005] A methyl anthranilate emulsification device includes a colloid mill, a base plate fixed to the bottom of the colloid mill, a feed hopper and a discharge pipe on the colloid mill, a return pipe on the discharge pipe, a support fixed to the base plate, a premixing tank fixed to the support, a discharge pipe at the bottom of the premixing tank, a stirring shaft inside the premixing tank, a stirring motor and stirring blades connected to the stirring shaft, multiple raw material inlet pipes connected to the upper part of the premixing tank, a removable cover plate fixed to the top of the feed hopper, a support sleeve one and a support sleeve two fixed to the top of the cover plate, the bottom of the discharge pipe extending into the support sleeve one, a liquid outlet elbow extending into the support sleeve two at the top of the return pipe, a section of corrugated pipe two on the liquid outlet elbow, and a section of corrugated pipe one on the discharge pipe.

[0006] As a preferred embodiment, the feed hopper is equipped with a cooling jacket, with a coolant inlet pipe at the lower part of the cooling jacket and a coolant outlet pipe at the upper part. This effectively reduces the temperature of the material entering the colloid mill from the feed hopper during operation, ensuring the emulsification quality of methyl anthranilate and extending the service life of the colloid mill.

[0007] As a preferred option, each stirring blade is evenly provided with liquid passage holes, which further increases the flow of liquid and enhances the mixing effect.

[0008] As a preferred embodiment, a distribution ring pipe is fixed on the inner wall of the top of the premix tank. The bottom of the distribution ring pipe is uniformly provided with distribution liquid holes. The inner ends of multiple raw material inlet pipes are connected to the distribution ring pipe and feed along the tangential direction of the distribution ring pipe. Multiple materials are initially mixed in the distribution ring pipe when they enter the premix tank, thereby increasing the mixing efficiency.

[0009] As a preferred embodiment, the bottom outer perimeter of the colloid mill is provided with a fixed flange one, and the top of the base plate is fixed with a fixed frame plate by bolts. The outer side of the fixed frame plate is fixed with a fixed flange two that cooperates with the fixed flange one. Multiple shock-absorbing rubber blocks are evenly arranged between the fixed flange one and the fixed flange two. A support screw is provided in the inner hole of the shock-absorbing rubber block. The two ends of the support screw pass through the fixed flange one and the fixed flange two respectively and are connected to locking nuts, which can better reduce vibration.

[0010] As a preferred option, the shock-absorbing rubber block is encased with a shock-absorbing spring, and a buffer rubber plate is provided between the locking nut below and the fixed flange two, which can better absorb shock.

[0011] As a preferred embodiment, two hemispherical liquid distribution heads are fixedly connected to the vertical section of the return pipe, and a cooling cylinder is fixed between the two liquid distribution heads. The upper and lower parts of the cooling cylinder are respectively provided with a second coolant outlet pipe and a second coolant inlet pipe. Multiple cooling pipes are evenly arranged between the two liquid distribution heads, which can cool the liquid in the return pipe and increase the liquid cooling effect.

[0012] The advantages of this utility model compared with the prior art are:

[0013] The colloid mill refines and emulsifies methyl anthranilate in the aqueous phase through grinding and shearing. Before entering the colloid mill, the methyl anthranilate and other materials are fully premixed, enabling the materials to achieve a good emulsification effect more quickly and improving emulsification efficiency. A removable cover plate is installed on the top of the feed hopper of the colloid mill to prevent dust from entering the feed hopper during emulsification, which can improve cleanliness. Furthermore, the setting of corrugated pipe one and corrugated pipe two ensures that the feed pipe and return pipe do not obstruct the removal of the cover plate, making it convenient to clean the colloid mill.

[0021] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] Example 1, Reference Figures 1 to 5 A methyl anthranilate emulsification device includes a colloid mill 12, a base plate 14 fixed to the bottom of the colloid mill 12, a feed hopper 10 and a discharge pipe 15 on the colloid mill 12, a return pipe 16 on the discharge pipe 15, a bracket fixed to the base plate 14, a premixing tank 3 fixed to the bracket, a discharge pipe 8 at the bottom of the premixing tank 3, a stirring shaft 2 inside the premixing tank 3, and a stirring motor 1 and a stirring blade 6 connected to the stirring shaft 2 (the stirring blade 6 is not limited to the motor). Other stirring structures can also be used, such as stirring impellers. The upper part of the premix tank 3 is connected to multiple raw material inlet pipes 5. The top of the feed hopper 10 is fixed with a detachable cover plate 20. The top of the cover plate 20 is fixed with a support sleeve 1 9 and a support sleeve 2 17. The bottom of the discharge pipe 8 extends into the support sleeve 1 9. The top of the return pipe 16 is provided with a liquid outlet elbow whose end extends into the support sleeve 2 17. A section of corrugated pipe 2 18 is provided on the liquid outlet elbow. A section of corrugated pipe 1 19 is provided on the discharge pipe 8.

[0023] During operation, methyl anthranilate and other related materials enter the premix tank 3 from multiple raw material inlets 5. The stirring motor 1 drives the stirring shaft 2 to rotate, and the stirring blades 6 on the stirring shaft 2 stir the materials to ensure thorough premixing. Then, the valve on the discharge pipe 8 is opened, and the materials enter the feed hopper 10 and then the colloid mill 12. The colloid mill 12 emulsifies the materials, and the materials will flow back into the feed hopper 10 through the return pipe 16. After the feed hopper 10 reaches a certain position, the valve on the discharge pipe 8 is closed. After the feed hopper 10 circulates and emulsifies for a period of time, the valve on the discharge pipe 15 is opened to discharge the emulsified liquid. When it is necessary to clean the feed hopper 10, the discharge pipe 8 and the liquid outlet elbow can be lifted upwards, so that the bottom of the discharge pipe 8 is removed from the support sleeve 1 9 and the liquid outlet elbow is removed from the support sleeve 2 17. Then, the cover plate 20 can be removed to clean the feed hopper 10.

[0024] In Example 2, based on Example 1, a cooling jacket 11 is provided on the outside of the feed hopper 10. A coolant inlet pipe is located at the lower part of the cooling jacket 11, and a coolant outlet pipe is located at the upper part of the cooling jacket 11. During emulsification, coolant is introduced into the coolant inlet pipe and discharged from the coolant outlet pipe, cooling the feed hopper 10 and thus the material inside. The cover plate 20 is made of transparent material, and sealing rings are provided in the inner walls of the support sleeve 1 9 and the support sleeve 2 17 for better sealing.

[0025] Each stirring blade 6 has evenly distributed liquid passage holes 7.

[0026] A distribution ring pipe 4 is fixed on the top inner wall of the premix tank 3. Distribution liquid holes are evenly distributed at the bottom of the distribution ring pipe 4. Multiple raw material inlet pipes 5 are connected to the inner ends of the distribution ring pipe 4 and feed material along the tangential direction of the distribution ring pipe 4. The materials entering through the multiple raw material inlet pipes 5 enter along the tangential direction of the distribution ring pipe 4, thus undergoing initial mixing within the distribution ring pipe 4, and then being evenly distributed from the bottom distribution liquid holes. A level sensor is installed at the top of the feed hopper 10. The level sensor is connected to a controller, which is connected to the valves on the discharge pipe 15 and the feed pipe 8. The controller is also connected to the drive motor of the colloid mill 12.

[0027] The bottom outer perimeter of the colloid mill 12 is provided with a fixed flange 13. The top of the base plate 14 is fixed with a fixed frame plate 21 by bolts. The outer side of the fixed frame plate 21 is fixed with a fixed flange 2 that cooperates with the fixed flange 13. Multiple shock-absorbing rubber blocks 22 are evenly arranged between the fixed flange 13 and the fixed flange 2. The inner hole of the shock-absorbing rubber block 22 is provided with a support screw 23. The two ends of the support screw 23 pass through the fixed flange 13 and the fixed flange 2 respectively and are connected to a locking nut.

[0028] The shock-absorbing rubber block 22 contains a shock-absorbing spring, and a buffer rubber plate is provided between the locking nut below and the fixed flange 2. When the colloid mill 12 is working, the vibration generated will be transmitted to the fixed flange 13. At this time, the shock-absorbing rubber block 22 between the fixed flange 13 and the fixed flange 2 will play a shock-absorbing role and reduce noise.

[0029] Two hemispherical liquid distribution heads 26 are fixedly connected to the vertical section of the return pipe 16. A cooling cylinder 24 is fixed between the two liquid distribution heads 26. The upper and lower parts of the cooling cylinder 24 are respectively provided with a second coolant outlet pipe and a second coolant inlet pipe. Multiple cooling pipes 25 are evenly arranged between the two liquid distribution heads 26. During operation, coolant is introduced into the second coolant inlet pipe, then flows in the cooling cylinder 24, and then exits from the second coolant outlet pipe. During this process, heat exchange occurs with the liquid in the multiple thin cooling pipes 25, thus better cooling the liquid.

[0030] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
