Description

Technical Field

[0001] The invention relates to the field of salicylic acid preparation and processing, and in particular to an emulsifying device for preparing salicylic acid. Background Art

[0002] Salicylic acid, chemically known as 2-hydroxybenzoic acid, is an important organic acid widely used in medicine, daily chemicals, pesticides, dyes and other fields. As a drug, salicylic acid has multiple pharmacological effects such as anti-rheumatic, anti-inflammatory and antipruritic. It is an important raw material or intermediate for the preparation of various drugs. In the preparation process of salicylic acid, emulsification is a key step. The emulsification device can disperse the immiscible oil phase and water phase in the form of tiny droplets in the other liquid through the action of emulsifiers to form a stable emulsion.

[0003] The emulsification effect in the preparation process of salicylic acid depends on the stirring effect. The existing emulsifying device for preparing salicylic acid has a single stirring mode and can only rotate in one direction, and the stirring position and mode cannot be well adjusted, resulting in poor emulsification effect of salicylic acid. At the same time, when adding an appropriate amount of distilled water or other liquids during the stirring process, it is often necessary to add them manually, but it is difficult for the operator to control the speed and amount of addition, which may cause uneven distribution of distilled water in the emulsification system, thereby affecting the emulsification effect and the stability of the final product, and cannot meet the actual use requirements.

DETAILED DESCRIPTION

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0040] Example 1

[0041] See also Figures 1 to 13 , an emulsifying device for preparing salicylic acid, comprising an emulsifying box 1, a supporting foot 53 for supporting is arranged at the bottom of the emulsifying box 1, a feeding pipe 2 is arranged on the emulsifying box 1, a first control valve 3 is arranged on the feeding pipe 2, and further comprising:

[0042] The annular rotating stirring mechanism is installed inside the emulsifying tank 1 and is used for performing annular rotating stirring treatment on the materials in the emulsifying tank 1. The annular rotating stirring mechanism includes a second rotating rod 31, a first rotating rod 28 and an annular ring 22 for annular rotating stirring processing. The annular ring 22 is limitedly rotated and installed inside the emulsifying tank 1.

The other end of the first rotating rod 28 is fixedly connected to a second stirring shaft 29, and a plurality of second stirring blades 30 are arranged on the second stirring shaft 29.

[0043] The stirring and infusion control mechanism is installed on the emulsification box 1, and is used to control the circular rotation and stirring of the second stirring shaft 29 and the synchronous rotation and stirring of the second stirring shaft 29 following the annular ring 22. The stirring and infusion control mechanism includes a first connecting shaft 9 and a connecting drum 18 for rotation control connection. The first connecting shaft 9 is fixedly connected to the output shaft of the driving motor 8. A plurality of first limiting plates 10 are arranged on the first connecting shaft 9. The connecting drum 18 is movably installed on the outer side of the first connecting shaft 9. A plurality of second limiting plates 19 are arranged inside the connecting drum 18, and one end of the connecting drum 18 is fixedly installed on the first fixing plate 20. The first fixing plate 20 is fixedly installed inside the annular ring 22 through a fixing rod 21.

[0044] Furthermore, the stirring infusion control mechanism also includes a square shaft 11 for driving the second rotating rod 31 to rotate, the first connecting shaft 9 is fixedly connected to the first stirring shaft 12 through the square shaft 11, one end of the second rotating rod 31 is fixedly connected to the second fixed plate 32, the second fixed plate 32 is limitedly rotated and installed on the first fixed plate 20, the second fixed plate 32 is provided with a square groove 33 that is adapted for sliding connection with the square shaft 11, and the first fixed plate 20 is provided with a avoidance groove 34 for avoiding the connection of the square shaft 11.

[0045] Furthermore, the stirring infusion control mechanism also includes a heating rod 13 for heating and a spiral stirring blade 15 for stirring at the bottom. Several heating rods 13 are arranged on the first stirring shaft 12. The first stirring shaft 12 is also provided with a first stirring blade 14 for stirring. The first stirring blade 14 and the heating rod 13 are arranged at intervals, and the spiral stirring blade 15 is fixedly connected to the first stirring shaft 12.

[0046] Furthermore, the stirring and infusion control mechanism also includes an auger blade 17 for assisting in discharging materials. One end of the first stirring shaft 12 is fixedly connected to a material guide shaft 16 , and the auger blade 17 is fixedly mounted on the material guide shaft 16 .

[0047] Furthermore, the stirring and infusion control mechanism also includes an electric push rod 7 for controlling the lifting and lowering connection of the first connecting shaft 9, the drive motor 8 is fixedly mounted on the top plate 6, the top plate 6 is fixedly connected to the output end of the electric push rod 7, and the electric push rod 7 is fixedly mounted on the emulsification box 1.

[0048] Furthermore, the annular rotating stirring mechanism also includes a first gear 24 and a second gear 26 connected to the first rotating rod 28 to drive the second stirring shaft 29 to rotate in an annular manner, the second gear 26 is fixedly connected to the third connecting shaft 27, the first gear 24 is meshedly connected to the second gear 26, the first gear 24 is rotatably mounted on the second rotating rod 31 through the second connecting shaft 25, and a plurality of teeth 23 meshingly connected to the first gear 24 are arranged on the inner side of the annular ring 22.

[0049] Furthermore, a discharge pipe 4 is fixedly connected to the bottom of the emulsification tank 1 , and a second control valve 5 is provided on the discharge pipe 4 .

[0050] Preferably, the material to be emulsified and stirred is injected from the feed pipe 2 on the emulsification box 1, and the output shaft of the driving motor 8 drives the square shaft 11 on the first connecting shaft 9 to rotate. Since the square shaft 11 is adapted to be limitedly connected to the inside of the second fixing plate 32, and the second fixing plate 32 is limitedly rotatably mounted on the first fixing plate 20, and since the first limiting plate 10 on the first connecting shaft 9 and the second limiting plate 19 in the connecting drum 18 do not contact each other, it can be seen that Figure 7 and Fig. 9 As shown, the rotation of the first connecting shaft 9 does not correspondingly drive the annular ring 22 connected to the connecting drum 18 to rotate. At this time, the square shaft 11 correspondingly drives the heating rod 13 and the first stirring blade 14 on the first stirring shaft 12 to rotate. The heating rod 13 heats the material in the emulsification box 1, and the first stirring blade 14 stirs the middle area of ​​the emulsification box 1. The spiral stirring blade 15 on the first stirring shaft 12 synchronously stirs the bottom of the emulsification box 1. In addition, the rotation of the first stirring shaft 12 correspondingly drives the auger blade 17 on the guide shaft 16 to rotate, thereby facilitating the material guiding and discharging processing at the discharge pipe 4, avoiding the blockage of the discharge, and significantly improving the discharge speed.

[0051] In addition, the square shaft 11 drives the second rotating rod 31 connected to the second fixed plate 32 to rotate continuously. Since the annular ring 22 is in a stationary and fixed position at this time, and the first gear 24 is meshed and connected to the teeth 23 on the inner side of the annular ring 22, the first rotating rod 28 on the third connecting shaft 27 is driven to rotate continuously under the relationship of meshing connection between the first gear 24 and the second gear 26. Therefore, the first rotating rod 28 drives the second stirring blade 30 on the second stirring shaft 29 to rotate accordingly. At this time, the rotation and stirring operation is performed with the center of the third connecting shaft 27 as the center, and since the second rotating rod 31 also rotates with the center of the first connecting shaft 9 as the center, the second stirring blade 30 on the second stirring shaft 29 rotates with the third connecting shaft 27 as the center and rotates with the center of the first connecting shaft 9 as the center. The range of rotation and stirring is greatly improved, thereby significantly improving the emulsification and stirring efficiency of salicylic acid.

[0052] By combining the two stirring modes of rotation and revolution, salicylic acid and emulsifier can be mixed and stirred more comprehensively and from multiple angles. This stirring method greatly improves the uniformity of the emulsion and the uniform dispersion of salicylic acid particles in the emulsifier, which not only shortens the emulsification time, but also improves the emulsification efficiency, making the production process more efficient.

[0053] When it is necessary to stir a specific fixed area in the emulsification box 1, such as stirring the outer area in the emulsification box 1 or the central area near the emulsification box 1, the top plate 6 drives the driving motor 8 to move upward, and the first limiting plate 10 on the first connecting shaft 9 moves toward the second limiting plate 19 in the connecting drum 18. When the first limiting plate 10 on the first connecting shaft 9 overlaps with the second limiting plate 19 in the connecting drum 18, the driving motor 8 is driven to rotate. Since the connecting drum 18 is fixedly installed on the first fixed plate 20, When the first connecting shaft 9 rotates, the connecting drum 18 rotates accordingly, so the connecting drum 18 synchronously drives the fixed rod 21 and the annular ring 22 connected to the first fixed plate 20 to rotate. At this time, the first gear 24 and the second gear 26 are in a relatively static position, so the first rotating rod 28 no longer rotates, so that the second stirring blade 30 on the second stirring shaft 29 follows the rotation of the annular ring 22 to perform a rotating stirring process, that is, the adjustment of the emulsification stirring process of the specific area in the emulsification box 1 is well realized, the adjustability is high, and the working efficiency of the emulsification stirring is significantly improved.

[0054] By adjusting the stirring position arbitrarily, the uniform distribution of salicylic acid in the emulsifier can be greatly improved. This uniformity helps to accelerate the emulsification process, improve the emulsification efficiency, and thus shorten the production cycle. The function of arbitrarily adjusting the stirring position allows the same equipment to adapt to a variety of different emulsification processing needs, which helps to improve equipment utilization, reduce equipment idle time, and thus reduce equipment investment costs.

[0055] Example 2

[0056] like Figures 1 to 8 As shown, based on Example 1, this embodiment further includes an infusion mechanism, which is installed inside the emulsification box 1 and is used for automatically adding liquid to the emulsification box 1. The infusion mechanism includes a first liquid conduit 48 and an infusion box 46 for infusion connection. The infusion box 46 is installed inside the emulsification box 1. The infusion box 46 is connected to the inside of the emulsification box 1 through the first liquid conduit 48. The first liquid conduit 48 is provided with a liquid outlet one-way valve 49.

[0057] Furthermore, the infusion mechanism also includes a curved rotating rod 39 and a rotating rod 41 for driving the infusion box 46 to make an infusion connection. The curved rotating rod 39 is rotatably installed inside the emulsification box 1. The curved rotating rod 39 is adapted to be rotatably connected with a rotating sleeve 40, and the rotating sleeve 40 is fixedly connected with the rotating rod 41. One end of the rotating rod 41 is hingedly installed on a hinge seat 42, and the hinge seat 42 is fixedly installed on a pressing plate 43. The pressing plate 43 is fixedly connected with a piston plate 45 through a piston rod 44. The piston plate 45 is limitedly slidably connected to the inside of the infusion box 46, and an air guide hole 47 is provided on the infusion box 46.

[0058] Furthermore, the infusion mechanism also includes a fourth connecting shaft 36 for driving the curved rotating rod 39 to rotate. The fourth connecting shaft 36 is rotatably installed inside the emulsification box 1. The fourth connecting shaft 36 is rotatably connected to the connecting drum 18 through a synchronous belt 35. The fourth connecting shaft 36 is fixedly connected to the third gear 37. The third gear 37 is meshed with a fourth gear 38. The diameter of the fourth gear 38 is larger than that of the third gear 37. The fourth gear 38 is fixedly installed on the curved rotating rod 39.

[0059] Furthermore, the infusion mechanism also includes a second liquid conduit 50 and a liquid storage tank 52 for injection connection. The infusion tank 46 is connected to the interior of the liquid storage tank 52 through the second liquid conduit 50. The liquid storage tank 52 is fixedly installed on the emulsification tank 1. The second liquid conduit 50 is provided with a liquid inlet one-way valve 51.

[0060] Preferably, in this embodiment, during the emulsification and stirring process, in order to further improve the emulsification efficiency, when it is necessary to add a proper amount of liquid such as distilled water, the height of the driving motor 8 can be correspondingly raised, so that the first limit plate 10 on the first connecting shaft 9 is raised to a position overlapping with the second limit plate 19 in the connecting drum 18. At this time, the rotation of the connecting drum 18 drives the third gear 37 on the fourth connecting shaft 36 to rotate under the synchronous driving action of the synchronous belt 35. The third gear 37 drives the curved rotating rod 39 to rotate in a meshing connection with the fourth gear 38. Since the diameter of the fourth gear 38 is larger than that of the third gear 37, so that the curved rotating rod 39 slowly drives the rotating rod 41 on the rotating sleeve 40 to move back and forth, that is, correspondingly drives the piston plate 45 on the piston rod 44 to slowly move back and forth inside the infusion box 46, so that under the connection relationship between the liquid inlet check valve 51 set on the second liquid guide tube 50 and the liquid outlet check valve 49 set on the first liquid guide tube 48, the liquid in the liquid storage tank 52 is extracted, and the extracted liquid is injected into the emulsification box 1 through the first liquid guide tube 48, so as to realize the addition operation of distilled water or other liquid in the emulsification box 1, without manual addition, which significantly improves the efficiency of salicylic acid emulsification processing.

[0061] This method of combining the rotation control of the stirring shaft with the automatic addition of liquids such as distilled water can significantly reduce manual operations, thereby reducing production costs and improving production efficiency. At the same time, the automated addition process can also reduce human errors and improve the product qualification rate. That is, distilled water can be added in a timely and even manner during the stirring process, thereby optimizing process conditions, improving product quality and performance, and further improving production efficiency.

[0062] It should be particularly noted that pulleys which are synchronously connected to the synchronous belt 35 are provided on the connecting drum 18 and the fourth connecting shaft 36 .
