[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 7 As shown, an embodiment of the present invention provides a nicotinamide reactor, comprising a fixing seat 1 and a reactor body 2, wherein the reactor body 2 is fixedly installed inside the fixing seat 1, a discharge port 3 is provided at the bottom of the reactor body 2, and a ventilation port 4 is provided on the outer wall of the reactor body 2;

[0029] A heating layer 5 is provided on the inner wall of the kettle body 2, a fixing plate 6 is fixedly installed in the middle of the heating layer 5, a guide groove 7 is provided inside the fixing plate 6, a stirring shaft 8 is provided inside the kettle body 2, a limiting rod 9 is fixedly installed at the bottom of the stirring shaft 8, a stirring rod 11 is movably installed on the outer wall of the stirring shaft 8, a slide groove 12 is provided on the left and right sides of the bottom of the stirring rod 11, guide blocks 10 matching the slide groove 12 are provided on the left and right sides of the limiting rod 9, the stirring rod 11 can slide up and down on the outer wall of the limiting rod 9 through the guide blocks 10, and sliders 13 are provided on the front and back sides of the top of the stirring rod 11, and two sets of sliders 13 are movably installed inside the guide groove 7.

[0030] When the staff needs to prepare nicotinamide, the staff can adopt a graded mixing method, first directly put part of the raw materials into the interior of the kettle body 2, and then start the motor 22. The operation of the motor 22 drives the driving wheel 21 to rotate, and further the driven wheel 14 rotates. The rotation of the driven wheel 14 will drive the feeding cylinder 15 to rotate. However, the feeding cylinder 15 and the stirring shaft 8 are fixedly connected, so that the stirring shaft 8 rotates synchronously. At this time, since the left and right sides of the limit rod 9 at the bottom of the stirring shaft 8 are provided with guide blocks 10, the stirring rod 11 will rotate when the stirring shaft 8 rotates. Further, the front and back sides of the stirring rod 11 are provided with sliders 13, and the sliders 13 are located inside the guide groove 7, so that when the stirring rod 11 rotates, the sliders 13 will slide along the guide groove 7. Further, the stirring rod 11 will rotate and stir the raw materials inside the kettle body 2 while sliding up and down along the guide blocks 10 to achieve multi-dimensional stirring and mixing. During mixing, the staff can start the heating layer 5 The solution is heated to accelerate the reaction of the raw materials, and then the staff can put the remaining raw material liquid into the storage tank 24 from the feeding port 25. At this time, the hot air generated inside the kettle body 2 will float upward and contact with the heat conducting plate 29. The further heat conducting pad 23 is heated by the heat conducting plate 29 to preheat the materials to be mixed inside the storage tank 24. After the raw materials inside the kettle body 2 are mixed to a certain extent, the staff can put in the remaining raw materials. At this time, the staff starts the water pump 26. The operation of the water pump 26 sends the raw material liquid inside the storage tank 24 to the inside of the feeding barrel 15 through the water pipe 27. As the liquid is injected, the movable plug 18 will be squeezed to compress the spring 19. Further, the discharge nozzle 16 is opened, and the raw material will be injected into the inside of the kettle body 2 through the discharge nozzle 16. At this time, because the driven wheel 14 drives the feeding barrel 15 to rotate, the discharge nozzle 16 will rotate during feeding, and the raw material will be evenly sprinkled on the inside of the kettle body 2 to ensure uniform mixing.

[0031] By rotating the stirring shaft 8, the limiting rod 9 drives the stirring rod 11 to rotate. Through the setting of the guide groove 7 on the inner wall of the fixed plate 6, when the stirring rod 11 rotates to mix the materials, the stirring rod 11 will also move up and down along the guide block 10, further realizing the dimensional stirring and mixing operation. Compared with the traditional plane stirring, the device can stir and turbulently stir the raw materials inside the kettle body 2 when the stirring rod 11 rises and falls during stirring, effectively improving the mixing efficiency, greatly reducing the flow dead angle during stirring, and effectively prolonging the preparation time of niacinamide and improving production efficiency.

[0032] Among them, a driven wheel 14 is rotatably installed on the top of the kettle body 2, a storage tank 24 is fixedly installed on the top of the kettle body 2, a feeding port 25 is opened on the top of the storage tank 24, a water pump 26 is fixedly installed on the right side of the feeding port 25, one end of the water pump 26 is connected to a water pipe 27, a bracket 28 is fixedly installed on the top of the kettle body 2, the bracket 28 is rotatably connected to the storage tank 24, a feeding barrel 15 is fixedly installed on the bottom of the driven wheel 14, a stirring shaft 8 is fixedly installed inside the feeding barrel 15, one end of the water pipe 27 is rotatably connected to the bracket 28 and is connected to the feeding barrel 15.

[0033] The staff starts the water pump 26, and the operation of the water pump 26 sends the raw material liquid inside the storage tank 24 into the interior of the feeding barrel 15 through the water pipe 27. As the liquid is injected, the movable plug 18 will be squeezed to compress the spring 19, and further the discharge nozzle 16 will be opened, and the raw material will be injected into the interior of the kettle body 2 through the discharge nozzle 16.

[0034] The driving wheel 21 is driven to rotate by the operation of the motor 22, and further, the driven wheel 14 meshing with the driving wheel 21 rotates, and the liquid in the storage tank 24 is transported to the inside of the feeding barrel 15 through the water pipe 27 through the operation of the water pump 26, and finally sprayed out from the discharge nozzle 16. Compared with the traditional feeding method, the device can transport the raw materials to the inside of the feeding barrel 15 through the water pump 26, and through the rotation of the discharge nozzle 16, the discharge nozzle 16 evenly sprays the raw materials inside the kettle body 2, which effectively improves the efficiency of raw material mixing, avoids the problem of uneven feeding, and improves the reaction rate and product quality.

[0035] A heat conducting plate 29 is fixedly mounted on the top inner wall of the kettle body 2, and a heat conducting pad 23 is fixedly mounted on the top of the kettle body 2. The heat conducting pad 23 is located between the material storage tank 24 and the heat conducting plate 29 for transferring heat.

[0036] The staff can add the remaining raw material liquid into the storage tank 24 from the feeding port 25. At this time, the hot air generated inside the kettle body 2 will float upward and contact the heat conducting plate 29. The heat conducting pad 23 is further heated by the heat conducting plate 29 to preheat the material to be mixed inside the storage tank 24.

[0037] By setting the heating layer 5, the staff can heat the solution inside the kettle 2 to increase its reaction rate during the stirring and mixing operation. After the internal temperature of the kettle 2 is increased by setting the heat conducting plate 29 and the heat conducting pad 23, the hot air will heat the heat conducting pad 23 through the heat conducting plate 29. Furthermore, the raw materials in the storage tank 24 will be preheated before adding. This makes the device energy-saving and environmentally friendly, and can also improve the mixing efficiency of the raw materials during graded addition, thereby reducing the workload.

[0038] The guide groove 7 is formed by a plurality of groups of arc grooves in a circumferential array and is in a corrugated shape. The slider 13 is located inside the guide groove 7 .

[0039] The slider 13 is located inside the guide groove 7 , so that when the stirring rod 11 rotates, the slider 13 will slide along the guide groove 7 , and further, the stirring rod 11 will rotate and stir the raw materials inside the kettle body 2 while sliding up and down along the guide block 10 .

[0040] Among them, discharge nozzles 16 are fixedly installed on the left and right sides of the outer wall of the feeding barrel 15, and the discharge nozzle 16 and the feeding barrel 15 are connected to each other.

[0041] A fixed rod 17 is fixedly installed inside the discharge nozzle 16 , and a movable plug 18 is movably installed inside the discharge nozzle 16 . The movable plug 18 is movably installed on the outer wall of the fixed rod 17 .

[0042] As the liquid is injected, the movable plug 18 will be squeezed to compress the spring 19, and the discharge nozzle 16 will be opened, and the raw material will be injected into the interior of the kettle body 2 through the discharge nozzle 16.

[0043] The inner wall of the movable plug 18 and the fixed rod 17 are elastically connected via a spring 19 , and the other end of the movable plug 18 blocks the connection between the feeding barrel 15 and the discharge nozzle 16 .

[0044] In the absence of feeding, the movable plug 18 will block the connection between the discharge nozzle 16 and the feeding barrel 15, further preventing the solution from flowing into the inside of the feeding barrel 15 and causing losses.

[0045] Among them, a fixing frame 20 is fixedly installed on the top of the kettle body 2, a motor 22 is fixedly installed on the top of the fixing frame 20, a driving wheel 21 is rotatably installed on the bottom of the fixing frame 20, the driving wheel 21 and the driven wheel 14 are meshed with each other, and the output shaft of the motor 22 is fixedly connected to the driving wheel 21.

[0046] The staff starts the motor 22 , and the operation of the motor 22 drives the driving wheel 21 to rotate, and further the driven wheel 14 rotates, and the rotation of the driven wheel 14 drives the feeding barrel 15 to rotate.

[0047] Working principle and usage process:

[0048] When the staff needs to prepare nicotinamide, the staff can adopt a graded mixing method, first directly put part of the raw materials into the interior of the kettle body 2, and then start the motor 22. The operation of the motor 22 drives the driving wheel 21 to rotate, and further the driven wheel 14 rotates. The rotation of the driven wheel 14 will drive the feeding cylinder 15 to rotate. However, the feeding cylinder 15 and the stirring shaft 8 are fixedly connected, so that the stirring shaft 8 rotates synchronously. At this time, since the left and right sides of the limit rod 9 at the bottom of the stirring shaft 8 are provided with guide blocks 10, the stirring rod 11 will rotate when the stirring shaft 8 rotates. Further, the front and back sides of the stirring rod 11 are provided with sliders 13, and the sliders 13 are located inside the guide groove 7, so that when the stirring rod 11 rotates, the sliders 13 will slide along the guide groove 7. Further, the stirring rod 11 will rotate and stir the raw materials inside the kettle body 2 while sliding up and down along the guide blocks 10 to achieve multi-dimensional stirring and mixing. During mixing, the staff can start the heating layer 5 The solution is heated to accelerate the reaction of the raw materials, and then the staff can put the remaining raw material liquid into the storage tank 24 from the feeding port 25. At this time, the hot air generated inside the kettle body 2 will float upward and contact with the heat conducting plate 29. The further heat conducting pad 23 is heated by the heat conducting plate 29 to preheat the materials to be mixed inside the storage tank 24. After the raw materials inside the kettle body 2 are mixed to a certain extent, the staff can put in the remaining raw materials. At this time, the staff starts the water pump 26. The operation of the water pump 26 sends the raw material liquid inside the storage tank 24 to the inside of the feeding barrel 15 through the water pipe 27. As the liquid is injected, the movable plug 18 will be squeezed to compress the spring 19. Further, the discharge nozzle 16 is opened, and the raw material will be injected into the inside of the kettle body 2 through the discharge nozzle 16. At this time, because the driven wheel 14 drives the feeding barrel 15 to rotate, the discharge nozzle 16 will rotate during feeding, and the raw material will be evenly sprinkled on the inside of the kettle body 2 to ensure uniform mixing.
