Description

Technical Field

[0001] The invention relates to the technical field of mixing equipment, and more specifically to a high-efficiency methyl salicylate preparation device. Background Art

[0002] Methyl salicylate is a colorless or light yellow or light yellow-red transparent oily liquid. It can be used as a solvent and intermediate, and can also be used in the formulation of daily chemical flavors. It is mainly used to formulate flavors such as ylang-ylang, tuberose, chypre, acacia, fougere, and jasmine. It is a widely used chemical product.

[0003] The shortcomings of the prior art are as follows: when preparing methyl salicylate, multiple substances need to be added, and then mixed and stirred for multiple times to finally form methyl salicylate.

[0031] The technical scheme of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are only examples. The high-efficiency methyl salicylate preparation device involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0032] like Figure 1-6As shown, in one embodiment, a high-efficiency methyl salicylate preparation device is proposed, including a reaction tank 1, a heating support seat 2 is arranged at the lower end of the reaction tank 1, a tank cover 101 is arranged at the upper end of the reaction tank 1, a through hole 102 is arranged at the upper end of the tank cover 101, and the through hole 102 is blocked by a block 103, a mixing assembly 3 is arranged in the reaction tank 1, the mixing assembly 3 includes a feeding mechanism 31 and a stirring mechanism 32, the feeding mechanism 31 includes a rotating seat 311, a rotating joint 312, a rotating rod 313 and a feeding pipe 316, the rotating seat 311 is installed at the lower end of the tank cover 101, the rotating joint 312 is rotatably connected in the rotating seat 311, the rotating rod 313 is installed at the lower end of the rotating joint 312, a cavity 314 is opened in the rotating rod 313, a discharge pipe 315 is installed on the circumferential surface of the rotating rod 313, and the feeding pipe 316 is installed in the tank cover 101, and the end of the feeding pipe 316 away from the tank cover 101 is connected to the rotating seat 311;

[0033] The stirring mechanism 32 includes a driving motor 321, a driving shaft 322, a clamping block 323 and a stirring rod 324. The driving motor 321 is installed on the upper end of the tank cover 101. The driving shaft 322 is installed at the output end of the driving motor 321 and is rotatably connected between the tank cover 101 and the rotating seat 311. The clamping block 323 is installed in the rotating joint 312. One end of the driving shaft 322 away from the driving motor 321 is located in the clamping block 323. A plurality of stirring rods 324 are all installed on the circumferential surface of the rotating rod 313. The rotating frame 325 installed on the inner wall of the reaction tank 1 is rotatably connected to the rotating rod 313.

[0034] An anti-blocking mechanism 4 is provided in the rotating rod 313 , and a separation mechanism 5 is provided in the reaction tank 1 .

[0035] In actual application of the embodiment of the present invention, after the initial materials for preparing methyl salicylate are input into the reaction tank 1, the initial materials are generally salicylic acid solid, methanol liquid and sulfuric acid, which are added in sequence. At this time, by controlling the operation of the driving motor 321, the driving motor 321 will drive the driving shaft 322 to rotate, and then under the action of the block 323, the driving shaft 322 will drive the rotating joint 312 to rotate, and the rotating joint 312 will drive the rotating rod 313 to rotate, thereby driving the multiple stirring rods 324 to stir and mix the materials. After mixing, the external reflux condensing device can be connected in the through hole 102. After cooling water is introduced, the heating effect is achieved under the action of the support seat, so that methanol and salicylic acid undergo esterification reaction. After the reaction is completed and cooled, the subsequent materials can be added. When liquid or solid powder is added, it is added through the feed pipe 316, and then these materials first enter the rotating seat 311 and the rotating joint 312, and finally enter the cavity 314 opened in the rotating rod 313, and finally enter the reaction tank 1 through the discharge pipe 315. Since the height of the discharge pipe 315 is relatively low, the material can directly enter the reaction liquid after being output from the discharge pipe 315. In particular, for some powdery or granular materials, when the traditional method of adding the material into the liquid from above is used, the material will be pushed and it is difficult to quickly dissolve into the reaction liquid. Under the stirring action of the stirring rod 324, the mixing effect of the subsequently added material and the reaction liquid is better, the mixing effect of the material addition is improved, the reaction speed after the material is mixed is increased, and the efficiency of preparing methyl salicylate is improved.

[0036] like Figure 4-8 As shown, as a preferred embodiment of the present invention, a mounting bracket 317 is installed on the surface of the reaction tank 1, and a first air pump 318 and a second air pump 319 are installed on the upper end of the mounting bracket 317. The output ends of the first air pump 318 and the second air pump 319 are connected to a venturi tube 3110, and the venturi tube 3110 is connected to the feed pipe 316 through a three-way pipe 3111. The end of the venturi tube 3110 away from the first air pump 318 and the second air pump 319 and the feed pipe 316 is connected to an input pipe 3112, and a pair of input pipes 3112 are respectively used to transport liquid materials and solid materials.

[0037] In actual application, the embodiment of the present invention is provided with a first air pump 318 and a second air pump 319, and the corresponding input pipe 3112 is used to input solid materials and liquid materials respectively. When inputting materials, the first air pump 318 or the second air pump 319 is controlled to operate, and then the external materials are extracted by negative pressure under the action of the venturi tube 3110 and the input pipe 3112, and then the materials can be input into the cavity 314 opened in the rotating rod 313 through the three-way pipe 3111 and the feed pipe 316, and finally discharged through the discharge pipe 316. The tube 315 is discharged at the middle and lower part of the reaction tank 1, and can be directly mixed with the liquid in the reaction tank 1. When the material is input, the material is transported by the airflow. When the material enters the liquid, it will enter with a large amount of gas. The gas will generate impact airflow and bubbles in the mixed liquid, promoting the rapid diffusion of the material. Then, through the cooperation with the rotating stirring of the stirring rod 324, the material can be quickly mixed when entering the liquid. When there is gas entering the reaction tank 1, the block 103 can be opened to allow the gas to be discharged through the through hole 102.

[0038] like Figure 6-9 As shown, as another preferred embodiment of the present invention, the anti-blocking mechanism 4 includes a rotating shaft 401, a pushing blade 402, a driven shaft 403, a linkage gear 405 and a gear ring 407. The rotating shaft 401 is rotatably connected in the rotating rod 313 and is rotatably connected between the block 323 and the driving shaft 322. The pushing blade 402 is installed on the circumferential surface of the rotating shaft 401 and is slidably connected to the inner wall of the rotating rod 313. The driven shaft 403 is rotatably connected in the rotating seat 311. The circumferential surface of the driven shaft 403 is fixedly connected with the first bevel gear 404 and the linkage gear 405. The upper end of the rotating shaft 401 is fixedly connected with the second bevel gear 406. The first bevel gear 404 is meshed with the second bevel gear 406. The gear ring 407 is installed in the rotating seat 311, and the linkage gear 405 is meshed with the gear ring 407.

[0039] In actual application of the embodiment of the present invention, when the driving shaft 322 rotates, the driving shaft 322 will drive the driven shaft 403 to rotate. At this time, under the action of the linkage gear 405 and the gear ring 407, the driven shaft 403 will rotate while revolving. At this time, the driven shaft 403 will drive the first bevel gear 404 to rotate, and the first bevel gear 404 will drive the second bevel gear 406 to rotate, thereby driving the rotating shaft 401 to rotate. Since there is a speed difference between the rotating shaft 401 and the rotating rod 313, the speed of the rotating shaft 401 is much higher than that of the rotating rod 313. At this time, the rotating shaft 401 will drive the pusher blade 402 to rotate, which can not only promote the downward transportation of the material, but also because the cavity 314 is a channel for conveying solid and liquid materials, the pusher blade 402 can prevent solid materials from adhering to the cavity 314 when it rotates, thereby achieving a cleaning effect on the cavity 314.

[0040] like Figure 6-8 As shown, as another preferred embodiment of the present invention, the anti-blocking mechanism 4 also includes a first bevel gear 408, a second bevel gear 4011, a rotating frame 409, a connecting shaft 4010 and a spiral blade 4012, the first bevel gear 408 is installed on the circumferential surface of the rotating shaft 401, the rotating frame 409 is installed in the discharge pipe 315, the connecting shaft 4010 is rotatably connected in the rotating frame 409, the second bevel gear 4011 and the spiral blade 4012 are both installed on the circumferential surface of the connecting shaft 4010, the spiral blade 4012 is slidably connected to the discharge pipe 315, and the first bevel gear 408 is meshed with the second bevel gear 4011.

[0041] In actual application of the embodiment of the present invention, when the rotating shaft 401 rotates, the rotating shaft 401 will drive the first bevel gear 408 to rotate, the first bevel gear 408 will drive the second bevel gear 4011 to rotate, the second bevel gear 4011 will drive the connecting shaft 4010 to rotate, and then drive the spiral blade 4012 to rotate. Since the position of the discharge pipe 315 is located in the mixed liquid, the spiral blade 4012 can rotate to push out the material located at the discharge pipe 315, thereby promoting the discharge of solid materials. The outlet of the discharge pipe 315 faces downward. After the material enters the liquid in the reaction tank 1 through the discharge pipe 315, the material will first be discharged downward, and then float upward with the large number of bubbles generated by the gas in the liquid, which can achieve a certain stirring effect on the liquid and further improve the mixing speed of the material.

[0042] like Figure 1 and 2 As shown, as another preferred embodiment of the present invention, a heating plate 201 is arranged in the heating support seat 2, and the heating plate 201 is attached to the lower end of the reaction tank 1, and the reaction tank 1 is made of transparent material.

[0043] In actual application, the embodiment of the present invention controls the heating disk 201 to generate heat, and the heating disk 201 transfers the heat to the liquid in the reaction tank 1 to promote the esterification reaction of the liquid in the reaction tank 1 .

[0044] like Fig.10 and 11 As shown, as another preferred embodiment of the present invention, the separation mechanism 5 includes a floating plate 503, a sliding seat 502, a sliding rod 501, a liquid extraction tube 504 and a liquid extraction head 505, a plurality of sliding rods 501 are installed on the inner wall of the reaction tank 1, the sliding seat 502 is slidably connected to the circumferential surface of the sliding rod 501, the floating plate 503 is installed between the sliding seats 502, the liquid extraction tube 504 is installed on the upper end of the floating plate 503, a plurality of liquid extraction heads 505 are installed on the liquid extraction tube 504, and the liquid extraction heads 505 penetrate the floating plate 503 and the lower ends are flush with the floating plate 503.

[0045] In actual application of the embodiment of the present invention, after the reaction liquid is esterified and subsequent materials are added, precipitation occurs in the reaction liquid. After precipitation, since the density of methyl salicylate is greater than that of water, methyl salicylate will precipitate below the water. At this time, the liquid in the reaction tank 1 is extracted by controlling the liquid extraction head 505 on the liquid extraction pipe 504, and the liquid located above will gradually decrease. As the water level drops, since the floating plate 503 floats on the water surface, the floating plate 503 will drop along with the water level until the floating plate 503 is attached to the position of methyl salicylate and the extraction is stopped, so that part of the liquid is extracted, and the separation and purification effect of methyl salicylate can be completed. At this time, the liquid remaining in the reaction tank 1 is the initially obtained methyl salicylate, and then the subsequent processing and preparation of methyl salicylate can be carried out, and the subsequent purification treatment can be carried out through the liquid extraction pipe 504.

[0046] like Fig.10 and 11 As shown, as another preferred embodiment of the present invention, an output pipe 506 is installed on the liquid extraction tube 504, and the output pipe 506 passes through the tank cover 101. A slide groove 507 is opened at the upper end of the tank cover 101, and an extrusion block 508 is slidably connected in the slide groove 507. The extrusion block 508 is used to extrude the output pipe 506. An electric push rod 509 is installed on the upper end of the tank cover 101, and the output end of the electric push rod 509 is connected to the extrusion block 508.

[0047] When the embodiment of the present invention is actually applied, a certain amount of liquid can be extracted through the output pipe 506 by controlling the external liquid extraction pump to complete the separation effect of methyl salicylate. At the same time, during the extraction process, the electric push rod 509 is controlled to retract to release the extrusion positioning of the output pipe 506. Since the output pipe 506 is a hose, part of the output pipe 506 will enter the reaction tank 1 as the position of the floating plate 503 decreases, while maintaining the vertical state of the output pipe 506 to avoid interference with the stirring rod 324. After a batch of methyl salicylate is prepared, after subsequent materials are added, the water level in the reaction tank 1 will increase, thereby causing the floating plate 503 to rise and reset. At the same time, the output pipe 506 is straightened during subsequent material addition, so that the output pipe 506 remains in a vertical state, and then the electric push rod 509 is controlled to push the extrusion block 508 to compress the output pipe 506.

[0048] like Figure 1 and 2 As shown, as another preferred embodiment of the present invention, a discharge port 6 is provided at the lower end of the reaction tank 1, a valve 601 is provided in the discharge port 6, a scraper 602 is fixedly connected to the circumferential surface of the rotating rod 313, and the scraper 602 is slidably connected to the reaction tank 1 and the discharge port 6.

[0049] In actual application of the embodiment of the present invention, after the preparation of methyl salicylate is completed, the valve 601 is opened, and the rotating rod 313 drives the scraper 602 to rotate, so that the prepared methyl salicylate can be discharged and collected.
