Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to a reactor. Background Art

[0002] In the production process of paraffin emulsion, paraffin needs to be melted first. In the production process, paraffin and emulsifier and other raw materials are first added into the reactor through the feed port, and then the stirring device is started to mix the raw materials. When the reaction is completed, the discharge port is opened to discharge the paraffin emulsion.

[0003] The existing reactor for producing paraffin emulsion has a slow chemical reaction rate because the stirring rod inside is always rotating in a fixed state. In addition, during the stirring process, the rotation of the stirring rod generates a large centrifugal force, which causes the reactor to vibrate and generate noise.

[0004] To this end, the present invention provides a reaction kettle. Summary of the invention

Through the extension and retraction of the side rod, the paraffin can be more effectively transferred from one area of ​​the kettle body to another area, reducing local concentration differences, improving the overall mixing uniformity, and helping to increase the contact area and collision frequency between the reactants, thereby promoting the chemical reaction. By setting a shock-absorbing mechanism, the centrifugal force generated by the rotation of the main hollow rod is absorbed and dispersed, and the impact of vibration on the kettle body and the surrounding environment is reduced. The shock-absorbing mechanism can also provide a certain elastic support, so that the kettle body can be more stable when subjected to external forces.

By extending and retracting the side rod 22, the paraffin can be more effectively transferred from one area of ​​the kettle body 1 to another area, reducing local concentration differences, improving the overall mixing uniformity, and helping to increase the contact area and collision frequency between the reactants, thereby promoting the chemical reaction. By setting the shock-absorbing mechanism 6, the centrifugal force generated by the rotation of the main hollow rod 2 is absorbed and dispersed, and the impact of vibration on the kettle body 1 and the surrounding environment is reduced. The shock-absorbing mechanism 6 can also provide a certain elastic support, so that the kettle body 1 can be more stable when subjected to external forces.

[0037] Specifically, the movable rod 44 is driven to move inside the fixed box 41 through the linkage 45, and then the movable rod 44 drives the movable plate 43 to reciprocate inside the fixed box 41. When the movable plate 43 moves inside the fixed box 41 toward the air pipe 42, the gas inside the fixed box 41 will be squeezed, and the gas will enter the main hollow rod 2 through the air pipe 42, thereby driving the side rod 22 in the secondary hollow rod 21 to extend. When the movable plate 43 moves inside the fixed box 41 and gradually moves away from the air pipe 42, the air in the main hollow rod 2 and the secondary hollow rod 21 will be extracted, and the gas will flow back into the fixed box 41, thereby retracting the side rod 22 in the secondary hollow rod 21. Through the extension and retraction of the side rod 22, paraffin can be more effectively transferred from one area of ​​the kettle body 1 to another, reducing local concentration differences, improving the overall mixing uniformity, and helping to increase the contact area and collision frequency between reactants, thereby promoting the progress of chemical reactions.

[0038] Please refer to Figure 1 and Figure 6 , the linkage member 45 includes a first connecting rod 451 and a second connecting rod 452; One end of the movable rod 44 away from the movable plate 43 is rotatably connected to the first connecting rod 451 , and the other end of the first connecting rod 451 is rotatably connected to the second connecting rod 452 .

[0039] Specifically, the second connecting rod 452 is rotated by the rotation of the main rotating rod 31 , so that the second connecting rod 452 drives the first connecting rod 451 to move, and the first connecting rod 451 drives the movable rod 44 to reciprocate inside the fixed box 41 .

[0040] Please refer to Figure 4 and Figure 5 The inner wall of each secondary hollow rod 21 is connected to a return spring 46 , and the other end of each return spring 46 is connected to the outer wall of the side rod 22 .

[0041] Specifically, when the pneumatic mechanism 4 extracts air from the main hollow rod 2 and the secondary hollow rod 21 , the side rod 22 can quickly return to its original position under the action of the return spring 46 .

[0042] Please refer to Figure 4 and Figure 5The inner wall of each secondary hollow rod 21 is connected to a sealing ring 47 , and the inner wall of each sealing ring 47 is in contact with the outer wall of the side rod 22 .

[0043] Specifically, under the action of the sealing ring 47 , the sealing effect between the secondary hollow rod 21 and the side rod 22 can be improved.

[0044] Please refer to Figure 2 and Figure 3 The side wall of the first gear 32 is meshed with an inner gear ring 35, the bottom end of the inner gear ring 35 is connected to a ring 36, the ring 36 is rotatably connected to the inner wall of the kettle body 1, the bottom end of the ring 36 is symmetrically connected to two scrapers 37, a sleeve 38 is commonly connected between the two scrapers 37, the sleeve 38 is rotatably connected to the bottom of the inner wall of the kettle body 1, and the main hollow rod 2 passes through the sleeve 38.

[0045] Specifically, the first gear 32 rotates, thereby driving the inner gear ring 35 to rotate inside the kettle body 1, thereby driving the ring 36 to rotate synchronously inside the kettle body 1, and the rotation of the ring 36 drives the two scrapers 37 to rotate together, and then the two scrapers 37 drive the sleeve 38 to rotate inside the kettle body 1, and the scraper 37 can scrape the inner wall of the kettle body 1 to prevent paraffin from adhering to the wall to form difficult-to-remove residues. The first gear 32 rotates to drive the second gear 33 and the inner gear ring 35 to rotate synchronously, and then the main hollow rod 2 and the scraper 37 rotate in opposite directions, which can further enhance the stirring effect and ensure the uniformity and consistency of the paraffin in the kettle body 1.

[0046] Please refer to Figure 2 and Figure 3 A plurality of stirring rods 371 are evenly connected to the two scrapers 37 , and the plurality of stirring rods 371 and the side rods 22 are arranged in a staggered manner at different heights.

[0047] Specifically, by providing a plurality of stirring rods 371, it is helpful to stir the paraffin better, because the stirring rods 371 and the side rods 22 of different heights can reach a wider area, which helps to improve the stirring and mixing efficiency.

[0048] Please refer to Figure 1 and Figure 2 , the shock absorbing mechanism 6 includes a foot seat 61, a shock absorbing spring 62, a rubber pad 63 and a shock absorber 64; The outer wall of each leg 5 is slidably connected to a foot seat 61, the inner wall of each foot seat 61 is connected to a shock-absorbing spring 62, the top end of each shock-absorbing spring 62 is connected to the bottom end of the leg 5, the bottom end of each foot seat 61 is glued to a rubber pad 63, the inner wall of each foot seat 61 is connected to a shock absorber 64, the top end of each shock absorber 64 is connected to the bottom end of the leg 5, and each shock-absorbing spring 62 is wrapped around the outer wall of the shock absorber 64.

[0049] Specifically, when the stirring operation begins inside the kettle body 1, the kettle body 1 drives the legs 5 to squeeze the shock-absorbing springs 62 inside the foot seats 61, allowing the legs 5 to slide inside the foot seats 61. Under the action of the shock-absorbing springs 62 and the shock absorbers 64, the legs 5 can return to their original positions. By setting up the shock-absorbing mechanism 6, the centrifugal force generated by the rotation of the main hollow rod 2 is absorbed and dispersed, thereby reducing the impact of vibration on the kettle body 1 and the surrounding environment. The shock-absorbing mechanism 6 can also provide a certain amount of elastic support, so that the kettle body 1 can be more stable when subjected to external forces.

[0050] Working principle: by opening the control valve on the feed port 11 of the kettle body 1, feeding into the kettle body 1, the motor 345 drives the secondary rotating rod 343 to rotate on the bracket 344, so that the secondary rotating rod 343 drives the second conical tooth 342 to rotate, and the second conical tooth 342 drives the first conical tooth 341 to rotate, and the first conical tooth 341 drives the main rotating rod 31 to rotate, and then the main rotating rod 31 drives the first gear 32 to rotate, and the main rotating rod 31 drives the first gear 32 to rotate, and the first gear 32 drives the second gear 33 to rotate, and the second gear 33 drives the main hollow rod 2 to rotate inside the kettle body 1, and then the main hollow rod 2 stirs the paraffin inside the kettle body 1, and the first gear 32 rotates, thereby driving the inner gear ring 35 to rotate inside the kettle body 1, thereby driving The movable ring 36 rotates synchronously inside the kettle body 1, and the two scrapers 37 are driven to rotate together by the rotation of the ring 36, and then the two scrapers 37 drive the sleeve 38 to rotate inside the kettle body 1. The scrapers 37 can scrape the inner wall of the kettle body 1 to prevent paraffin from adhering to the wall to form residues that are difficult to remove. The second gear 33 and the inner gear ring 35 are driven to rotate synchronously by the rotation of the first gear 32, so that the main hollow rod 2 and the scrapers 37 rotate in opposite directions, which can further enhance the stirring effect and ensure the uniformity and consistency of the paraffin in the kettle body 1. The provision of multiple stirring rods 371 helps to better stir the paraffin, because the stirring rods 371 of different heights and the side rods 22 can reach a wider area, which helps to improve the efficiency of stirring and mixing. The second connecting rod 452 is driven to rotate by the rotation of the main rotating rod 31, so that the second connecting rod 452 drives the first connecting rod 451 to move, and the first connecting rod 451 drives the movable rod 44 to move back and forth inside the fixed box 41. When the movable plate 43 moves inside the fixed box 41 toward the air pipe 42, the gas inside the fixed box 41 is squeezed, so that the gas enters the main hollow rod 2 through the air pipe 42, thereby driving the side rod 22 in the secondary hollow rod 21 to extend. When the movable plate 43 moves inside the fixed box 41 and gradually moves away from the air pipe 42, the side rod 22 in the secondary hollow rod 21 is extended. The air in the hollow rod 21 is extracted, and the gas is allowed to flow back into the fixed box 41, so that the side rod 22 in the secondary hollow rod 21 is retracted. By extending and retracting the side rod 22, the paraffin can be more effectively transferred from one area of ​​the kettle body 1 to another area, reducing the local concentration difference, improving the overall mixing uniformity, and helping to increase the contact area and collision frequency between the reactants, thereby promoting the chemical reaction. When the pneumatic mechanism 4 extracts the air in the main hollow rod 2 and the secondary hollow rod 21, the side rod 22 can quickly return to its original position under the action of the return spring 46; When the stirring operation starts inside the kettle body 1, the kettle body 1 drives the legs 5 to squeeze the shock-absorbing springs 62 inside the foot seats 61, so that the legs 5 slide inside the foot seats 61. Under the action of the shock-absorbing springs 62 and the shock absorbers 64, the legs 5 can return to their original positions. By setting up the shock-absorbing mechanism 6, the centrifugal force generated by the rotation of the main hollow rod 2 is absorbed and dispersed, thereby reducing the impact of vibration on the kettle body 1 and the surrounding environment. The shock-absorbing mechanism 6 can also provide a certain amount of elastic support, so that the kettle body 1 can be more stable when subjected to external forces.
