Description

Technical Field

[0001] The utility model relates to the field of sodium salicylate, in particular to a sodium salicylate production device. Background Art

[0002] Sodium salicylate is an organic substance, white flakes or powder, odorless, turns pink when exposed to light for a long time, soluble in water and glycerin, insoluble in organic solvents such as ether, chloroform, benzene, and flammable when exposed to fire. It is mainly used in analgesics and rheumatism drugs, and is also used in organic synthesis. In the production process of sodium salicylate, a neutralization reaction is required to stir the salicylic acid solution with the sodium carbonate solution. To generate sodium salicylate through the neutralization reaction, the salicylic acid solution needs to be added to the reactor, and then the sodium carbonate solution is gradually added. Salicylic acid reacts with sodium carbonate to generate a sodium salicylate solution. This entire process requires the use of a production device.

[0003] After searching, a high-efficiency reactor for aminosalicylic acid production with publication number CN216093619U is disclosed, which specifically discloses a high-efficiency reactor for aminosalicylic acid production, including device legs, support vertical rods bolted to the top of the device legs, rubber columns bolted to the top of the support vertical rods, a reactor frame bolted to the top of the rubber columns, a PLC controller bolted to the outer wall of the reactor frame, a reactor shell sleeved on the inner wall of the reactor frame, a pressure door detachably connected to the top of the reactor shell, a power box bolted to the bottom of the reactor shell, a stirring device connected to the top flange of the pressure door, a main material inlet pipe and an auxiliary material inlet pipe are arranged on the top of the pressure door, a heating device and a reactor are arranged on the inner wall of the reactor shell, the device legs provide support for the utility model and improve the stability of the utility model, the rubber columns improve the seismic resistance of the utility model, the pressure door facilitates the internal pressure generation and improves the reaction efficiency of the utility model, and the heating device provides heat to the heating chamber and improves the uniformity of heat generation.

[0004] In the use process of the existing sodium salicylate production device, when mixing and stirring salicylic acid and sodium carbonate, the internal salicylic acid and sodium carbonate are only heated by heat transfer by an external heating device, and then simply stirred by a stirring rod. In this way, not only the fusion reaction speed of salicylic acid and sodium carbonate is slow, but also the effect after the fusion reaction is not good. In addition, the above comparative case also lacks means to enhance the mixing degree of salicylic acid and sodium carbonate and uniform heating. In this way, after the sodium salicylate production device is used for a long time, not only the overall production time is extended, but also the production efficiency is reduced.

[0005] Therefore, it is necessary to invent a sodium salicylate production device to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a sodium salicylate production device, which realizes a positive and a reverse rotation inside the sodium salicylate production device through a servo motor, a transmission rod, an inner mixing barrel, an outer embedded groove, a serpentine heating tube, a hot air blower and a hot air duct, not only strengthening the mixing means of the sodium salicylate production device for salicylic acid and sodium carbonate, but also such a heat covering type stirring and mixing method allows salicylic acid and sodium carbonate to react more thoroughly, thereby improving the production time and production efficiency of the sodium salicylate, so as to solve the problem that in the prior art, when the sodium salicylate production device is used, when mixing and stirring salicylic acid and sodium carbonate, only an external heating device is used to heat the internal salicylic acid and sodium carbonate, and then the simple stirring of the stirring rod is combined, so that not only the fusion reaction speed of salicylic acid and sodium carbonate is slow, but also the effect after the fusion reaction is not good, and the above comparative case also lacks the means for strengthening the mixing degree of salicylic acid and sodium carbonate and heating uniformly, so that after the sodium salicylate production device is used for a long time, not only the overall production time is extended, but also the production efficiency is reduced.

[0016] 1. The utility model is provided with a servo motor, a transmission rod, an inner mixing barrel, an outer embedded groove, a serpentine heating pipe, a hot air blower and a hot air duct.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-5 A sodium salicylate production device shown includes a reaction barrel 1 for carrying salicylic acid and sodium carbonate for fusion reaction;

[0028] A servo motor 4 is arranged at the bottom of the reaction barrel 1, and is used to drive the internal components to rotate. The output end of the servo motor 4 is fixedly connected to a transmission rod 5, and an inner mixing barrel 6 is fixedly installed at one end of the transmission rod 5. An outer embedding groove 7 is provided on the outside of the inner mixing barrel 6, and a serpentine heating tube 8 is fixedly installed inside the outer embedding groove 7;

[0029] A fixed buckle 9 is arranged on the outside of the reaction barrel 1 for connecting the upper barrel cover, and a fixed block 10 is movably connected inside the fixed buckle 9, and an upper closing cover 11 is fixedly installed on one end of the fixed block 10. A hot air blower 12 is fixedly installed outside the reaction barrel 1, and a hot air duct 13 is fixedly installed on one end of the hot air blower 12. Salicylic acid and sodium carbonate can be put into the inner mixing barrel 6 for mixing and stirring. The servo motor 4 synchronously drives the inner mixing barrel 6 to rotate in the opposite direction, thus forming a positive and negative rotation with the bottom stirring frame 19, so that the internal salicylic acid and sodium carbonate are mixed and stirred in a spiral state, and then the hot air blower 12 and the hot air duct 13 are used to inject hot air into the inner mixing barrel 6, and the serpentine heating tube 8 is used to form heat transfer to the barrel wall, so that the entire salicylic acid and sodium carbonate are heated and mixed more thoroughly.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, a fixing bolt 2 passes through the outside of the reaction barrel 1, and a support rod 3 is fixedly installed at one end of the fixing bolt 2. The support rod 3 raises the entire external reaction barrel 1 to prevent the reaction barrel 1 from contacting the ground and causing moisture transfer to affect the internal sodium salicylate production reaction effect. The number of fixing buckles 9 is set to six, and the six fixing buckles 9 are distributed in a ring array on the reaction barrel 1. The overall structure of the fixing buckles 9 and the fixing blocks 10 is simple and easy to operate. After the sodium salicylate is mixed, it is convenient for external operators to directly open the upper closing cover 11 to take out the inner mixing barrel 6 and pour out the mixed sodium salicylate for the next production process.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, a feed pipe 14 is fixedly installed on the top of the upper closing cover 11, a connecting flange 15 is fixedly installed on the outside of the feed pipe 14, and an air vent 16 is provided on one side of the feed pipe 14. The feed pipe 14 is connected to the external sodium salicylate raw material, which is convenient for operators to add salicylic acid and sodium carbonate to the inside at a uniform speed. A drive motor 17 is fixedly installed on the top of the upper closing cover 11, and a connecting rod 18 is fixedly connected to the output end of the drive motor 17, and a bottom stirring frame 19 is fixedly installed on the other end of the connecting rod 18. The upper closing cover 11 can seal the inner mixing barrel 6 more firmly through the fixed buckle 9 and the fixed block 10 to avoid overflow of the salicylic acid and sodium carbonate inside during the up and down rotation. The bottom stirring frame 19 is movably connected to the inner mixing barrel 6, and the connecting rod 18 coincides with the center line of the bottom stirring frame 19. The bottom stirring frame 19 is driven to rotate by the drive motor 17 to complete the forward rotating mixing and stirring of salicylic acid and sodium carbonate.

After the preparation work is completed, the salicylic acid and sodium carbonate can be mixed and stirred, and the switch of the driving motor 17 is turned on first, and the driving motor 17 drives the salicylic acid and sodium carbonate inside the entire inner mixing barrel 6 to rotate forwardly through the bottom stirring frame 19, and then the switch of the servo motor 4 is turned on, and the servo motor 4 is synchronously driven by the inner mixing barrel 6 to rotate in the opposite direction, so that a positive and a reverse rotation is formed with the bottom stirring frame 19, so that the internal water Salicylic acid and sodium carbonate are mixed and stirred in a spiral shape, and then the hot air is injected into the inner mixing barrel 6 by the hot air blower 12 and the hot air duct 13, so that the whole salicylic acid and sodium carbonate are heated and mixed more thoroughly, which not only strengthens the mixing means of the sodium salicylate production device for salicylic acid and sodium carbonate, but also such a heat covering stirring and mixing method allows salicylic acid and sodium carbonate to react more thoroughly. After waiting for the sodium salicylate to react, the upper closing cover 11 can be directly opened through the fixing buckle 9 and the fixing block 10 to take out the inner mixing barrel 6 and pour out the mixed sodium salicylate to carry out the next production process. Finally, after completing the installation and use of the entire sodium salicylate production device according to the above operation, turn off the switch of the servo motor 4, turn off the switch of the serpentine heating tube 8, turn off the switch of the hot air blower 12, turn off the switch of the drive motor 17, and cut off the external power supply if it is not used for a long time. In this way, the use process of the sodium salicylate production device is completed.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
