Abstract
Description
Technical Field
[0001] The present application relates to the technical field of silicone grease production, and in particular to a constant temperature reaction kettle. Background Art
[0002] In the production process of silicone grease, in addition to adding the corresponding reaction raw materials, it is also necessary to cooperate with the stirring mechanism to stir the raw materials so that they can be fully mixed and reacted. On this basis, some reactions need to reach certain reaction conditions, such as temperature. Therefore, in the production process of some silicone grease, a constant temperature reactor is needed, which can achieve the stirring of the raw materials while ensuring the corresponding reaction temperature.
[0003] Although traditional reactors have stirring and heating functions, a common problem is that the heating is not uniform and the internal raw materials are not heated evenly. This may cause local raw materials to react faster while some other locations react slower, which may cause an increase in side reactants and affect the quality of silicone grease. Utility Model Content
[0004] The purpose of this application is to provide a constant temperature reactor to solve at least one of the above technical problems.
[0005] In order to solve the above technical problems, the present application provides a constant temperature reactor, comprising an outer shell and a reactor body arranged in the outer shell;
[0006] A water inlet is provided near the upper end of the side wall of the outer shell, a water outlet is provided near the lower end, a plurality of heating units are distributed on the inner wall and the bottom, and water is filled between the reactor body and the inner wall of the outer shell;
[0007] The reactor body comprises a main shell, a rotary drive member, a rotary shaft, a rotary frame, a linkage assembly and a first stirring assembly; the rotary drive member is arranged at the upper end of the main shell, the rotary shaft is arranged at the driving end of the rotary drive member, the rotary shaft and the rotary frame are coaxially arranged and the rotary shaft passes through the rotary frame, the linkage assembly connects the rotary shaft and the rotary frame so that the rotary shaft and the rotary frame rotate in opposite directions, and the first stirring assembly is arranged on the rotary shaft; a feed port is arranged at the upper end of the main shell, and a discharge port is arranged on the side wall near the lower end, and the discharge port passes through and extends out of the outer shell;
[0008] Wherein, when the first stirring component rotates, it is suitable for driving the reaction liquid to move away from the axis, and when the rotating frame rotates, it is suitable for driving the reaction liquid to move close to the axis;
[0009] In the above implementation process, the staff adds the reaction liquid into the main shell from the feed port, and adds water into the space between the outer shell and the reactor body from the water inlet, and then starts the heating unit to heat the water to achieve water bath heating. The heat of the water can be transferred to the outside of the main shell and further to the reactor body; when the reaction is carried out, the rotating drive member drives the rotating shaft to rotate, and further drives the first stirring component to rotate to stir and mix the raw materials. It can be understood that at this time, the first stirring component stirs the slurry from the axis to the outside, and while the rotating shaft rotates, under the action of the linkage component, the rotating frame follows the rotation and is in the opposite direction to the first stirring component. Rotation, the rotating frame can also drive the raw materials to move, which drives the raw materials to be pushed into the axis from the outside, and finally the raw materials are fully mixed under the cooperation of the two. In this scheme, the raw materials in the reactor body are fully mixed by double rotation, which can avoid the situation where the local temperature is high and the local temperature is too low, and the raw materials inside the reactor are kept at a relatively balanced temperature as much as possible, so that the reaction conditions are in a balanced and equal state, the production of side reactions is reduced, and the quality of the final product is improved. In addition, the water bath constant temperature heating method is used in conjunction with multiple heating units to avoid the problem of local excessive temperature affecting the reaction of the raw materials due to the concentration of the heating source in the same place.
[0010] Preferably, the rotating frame comprises a cylindrical frame body, the frame body is formed with a receiving groove, the first stirring component is located in the receiving groove, and the rotating shaft passes through the frame body and penetrates into the receiving groove;
[0011] A plurality of second stirring paddles are arranged around the periphery of the frame;
[0012] In the above implementation process, the frame constitutes the main structure and provides an assembly position for the second stirring paddle. Of course, it is understandable that in some embodiments, the second stirring paddle and the frame can also be made into one piece; when the rotating frame rotates, it drives the second stirring paddle to rotate, and the second stirring paddle drives the raw material to move closer to the axis.
[0013] Preferably, the linkage assembly comprises a first gear, a second gear and a reversing gear respectively meshing with the first gear and the second gear;
[0014] Wherein, the first gear is coaxially arranged with the rotating shaft, and the second gear is coaxially arranged with the rotating frame;
[0015] In the above implementation process, when the rotating shaft rotates, it will drive the first gear to rotate, and the steering gear is respectively engaged with the first gear and the second gear, so the first gear drives the second gear to rotate through the steering gear, and the second gear is connected to the rotating frame, so that the rotating frame forms a rotation direction opposite to the rotating shaft, and finally drives the rotating frame to rotate in the opposite direction.
[0016] Preferably, the lower end of the rotating shaft passes through the main housing and is provided with a third stirring paddle;
[0017] In the above implementation process, when the rotating shaft rotates, it can also drive the third stirring paddle to rotate. The third stirring paddle can be understood as being located between the reactor body and the outer shell. When it rotates, it can stir the heated water, thereby further promoting the uniformity of the water temperature, so that the water on the outer wall of the main shell presents a balanced temperature state, which is more conducive to achieving a constant temperature reaction.
[0018] Preferably, a sealing ring is provided at the lower end of the main housing between the rotating shaft and the main housing;
[0019] In the above implementation process, the sealing ring can further enhance the sealing between the rotating shaft and the main shell, thereby reducing the risk of raw materials overflowing from the reactor body and the risk of water infiltrating from outside the reactor body, thereby ensuring the stability of the reaction process.
[0020] Preferably, the first stirring assembly comprises a fixed disk and a plurality of first stirring paddles circumferentially arranged around the fixed disk;
[0021] The fixed disc is coaxially arranged with the rotating shaft;
[0022] In the above implementation process, the fixed disc is coaxially connected to the rotating shaft. When the rotating shaft rotates, it can drive the fixed disc to rotate, and then drive the multiple first stirring paddles to rotate to stir the raw materials.
[0023] Preferably, the first stirring paddle comprises a V-shaped main body connected to the fixed disc and folded edges extending along both sides of the main body; the angle range of the corner of the main body is 100°-135°; the angle between the folded edge and the main body is 90°-150°;
[0024] A plurality of first through holes are provided on the folded edge portion;
[0025] In the above implementation process, there is a certain angle between the main body and the folded edge portion, and a first through hole is opened on the folded edge portion. When the first stirring paddle rotates, part of the raw material will pass through the first through hole. Since the first through hole has a certain vertical bias, the raw material will produce a part of vertical movement mixing at this time. In this way, during the rotation process, not only the raw materials are mixed in the horizontal direction, but also part of the raw materials are mixed in the vertical direction, thereby improving the mixing efficiency.
[0026] Preferably, a plurality of second through holes are provided on the main body.
[0027] In the above implementation process, a second through hole is provided on the main body, which can further improve the movable direction of the raw materials and accelerate the mixing of the raw materials.
[0028] Compared with the prior art, the beneficial effects of the present application are as follows: in the present solution, the double rotation is used to ensure that the raw materials in the reactor body are fully mixed, thereby avoiding the situation where the local temperature is high and the local temperature is too low, and the raw materials inside the reactor are kept at a relatively balanced temperature as much as possible, so that the reaction conditions are in a balanced and equal state, the production of side reactions is reduced, and the quality of the final product is improved; in addition, the water bath constant temperature heating method is used in conjunction with multiple heating units to avoid the problem of the local temperature being too high affecting the raw material reaction due to the concentration of the heating source in the same place.

[0043] Example
[0044] Although the traditional reactor has stirring and heating functions, the common problem is that the heating is not uniform and the internal raw materials are not heated uniformly; this may cause local raw materials to react faster, while some parts react slower, which may cause an increase in side reactions and affect the quality of silicone grease; In order to solve the above technical problems, this embodiment provides the following technical solutions:
[0045] For details, see Figure 1-5 , this embodiment provides a constant temperature reactor, comprising an outer shell 10 and a reactor body 20 disposed in the outer shell 10;
[0046] For details, see Figure 1-2 A water inlet 11 is provided near the upper end of the side wall of the outer shell 10, a water outlet 12 is provided near the lower end, a plurality of heating units 13 are distributed on the inner wall and the bottom, and water is filled between the reactor body 20 and the inner wall of the outer shell 10;
[0047] Specifically, the reactor body 20 includes a main shell 21, a rotary drive member 22, a rotary shaft 23, a rotary frame 25, a linkage assembly 26 and a first stirring assembly 24; the rotary drive member 22 is arranged at the upper end of the main shell 21, the rotary shaft 23 is arranged at the driving end of the rotary drive member 22, the rotary shaft 23 and the rotary frame 25 are coaxially arranged and the rotary shaft 23 passes through the rotary frame 25, the linkage assembly 26 connects the rotary shaft 23 and the rotary frame 25 so that the rotary shaft 23 and the rotary frame 25 rotate in opposite directions, and the first stirring assembly 24 is arranged on the rotary shaft 23; a feed port 211 is provided at the upper end of the main shell 21, and a discharge port 212 is provided on the side wall near the lower end, and the discharge port 212 passes through and extends out of the outer shell 10;
[0048] The first stirring component 24 is adapted to drive the reaction liquid to move away from the axis when rotating, and the rotating frame 25 is adapted to drive the reaction liquid to move closer to the axis when rotating;
[0049] In the above scheme, the staff adds the reaction liquid into the main shell 21 from the feed port 211, and adds water into the space between the outer shell 10 and the reactor body 20 from the water inlet 11, and then starts the heating unit 13 to heat the water body to achieve water bath heating. The heat of the water body can be transferred to the outside of the main shell 21 and further to the reactor body 20; when the reaction is carried out, the rotating drive member 22 drives the rotating shaft 23 to rotate, and further drives the first stirring component 24 to rotate to stir and mix the raw materials. It can be understood that at this time, the first stirring component 24 stirs the slurry from the axis to the outside. While the rotating shaft 23 rotates, under the action of the linkage component 26, the rotating frame 25 follows the rotation and rotates with the first stirring component 2 4 rotates in the opposite direction, and the rotating frame 25 can also drive the raw materials to move (the raw materials can be understood as the reaction liquid mentioned above), which drives the raw materials to be pushed into the axis from the outside, and finally the raw materials are fully mixed under the cooperation of the two. In this scheme, the raw materials in the reactor body 20 are fully mixed by double rotation, so as to avoid the situation where the local temperature is high and the local temperature is too low, and the raw materials inside the reactor are guaranteed to be at a relatively balanced temperature as much as possible, so that the reaction conditions are in a balanced and equal state, the generation of side reactions is reduced, and the quality of the final product is improved. In addition, the water bath constant temperature heating method is used to cooperate with multiple heating units 13 at the same time to avoid the problem that the heating source is concentrated in the same place and the local temperature is too high to affect the reaction of the raw materials.
[0050] It should be noted that the provision of a heating unit 13 in the barrel for heating the water is a relatively mature technology in the prior art, so this solution will not be further elaborated on this; the specific form of the heating unit 13 can be a heating wire, a heating plate or other mechanism that can achieve heating.
[0051] For details, see Figure 3 The rotating frame 25 includes a cylindrical frame body 251, the frame body 251 is formed with a receiving groove, the first stirring assembly 24 is located in the receiving groove, and the rotating shaft 23 penetrates the frame body 251 and penetrates into the receiving groove;
[0052] Furthermore, a plurality of second stirring paddles 252 are disposed around the outer periphery of the frame 251.
[0053] In the above scheme, the frame 251 constitutes the main structure and provides an assembly position for the second stirring paddle 252. Of course, it is understandable that in some embodiments, the second stirring paddle 252 and the frame 251 can also be made into one piece; when the rotating frame 25 rotates, it drives the second stirring paddle 252 to rotate, and the second stirring paddle 252 drives the raw material to move closer to the axis.
[0054] Specifically, the linkage assembly 26 includes a first gear 261, a second gear 262, and a reversing gear 263 meshing with the first gear 261 and the second gear 262 respectively;
[0055] The first gear 261 is coaxially arranged with the rotating shaft 23, and the second gear 262 is coaxially arranged with the rotating frame 25;
[0056] In the above scheme, when the rotating shaft 23 rotates, it drives the first gear 261 to rotate, and the steering gear is respectively engaged with the first gear 261 and the second gear 262, so the first gear 261 drives the second gear 262 to rotate through the steering gear, and the second gear 262 is connected to the rotating frame 25, so that the rotating frame 25 forms a rotation direction opposite to the rotating shaft 23, and finally drives the rotating frame 25 to rotate in the opposite direction.
[0057] Specifically, the lower end of the rotating shaft 23 passes through the main housing 21 and is provided with a third stirring paddle 30;
[0058] In the above scheme, when the rotating shaft 23 rotates, it can also drive the third stirring paddle 30 to rotate. The third stirring paddle 30 can be understood as being located between the reactor body 20 and the outer shell 10. When it rotates, it can stir the heated water, thereby further promoting the uniformity of the temperature of the water, so that the water on the outer wall of the main shell 21 presents a balanced temperature state, which is more conducive to achieving a constant temperature reaction.
[0059] Specifically, a sealing ring 31 is provided at the lower end of the main housing 21 between the rotating shaft 23 and the main housing 21;
[0060] In the above scheme, the sealing ring 31 can further enhance the sealing between the rotating shaft 23 and the main shell 21, thereby reducing the risk of raw materials overflowing from the reactor body 20 and the risk of water infiltrating from outside the reactor body 20, thereby ensuring the stability of the reaction process.
[0061] It is understandable that a sealing ring 31 may be further provided at the position where the discharge port 212 passes through the outer shell 10 .
[0062] Furthermore, both the material outlet 212 and the water outlet 12 may be provided with solenoid valves to control the outflow of liquid, which is a relatively mature prior art and will not be further elaborated in this application.
[0063] Specifically, the first stirring assembly 24 includes a fixed disk 241 and a plurality of first stirring paddles 242 circumferentially arranged around the fixed disk 241;
[0064] Furthermore, the fixed disc 241 is coaxially arranged with the rotating shaft 23;
[0065] In the above solution, the fixed disc 241 is coaxially connected to the rotating shaft 23. When the rotating shaft 23 rotates, it can drive the fixed disc 241 to rotate, and then drive the plurality of first stirring paddles 242 to rotate to stir the raw materials.
[0066] For details, see Figure 4-5 The first stirring paddle 242 includes a V-shaped main body 2421 connected to the fixed disk 241 and a folded edge 2422 extending along both sides of the main body 2421; the angle range of the corner of the main body 2421 is 100°-135°; the angle between the folded edge 2422 and the main body 2421 is 90°-150°;
[0067] Furthermore, a plurality of first through holes 2423 are provided on the folded edge portion 2422;
[0068] In the above scheme, there is a certain angle between the main body 2421 and the folded edge portion 2422, and a first through hole 2423 is opened on the folded edge portion 2422. When the first stirring paddle 242 rotates, part of the raw material will pass through the first through hole 2423. Since the first through hole 2423 has a certain vertical bias, the raw material will produce a part of vertical movement mixing at this time. In this way, during the rotation process, not only the raw materials are mixed in the horizontal direction, but also part of the raw materials are mixed in the vertical direction, thereby improving the mixing efficiency.
[0069] Specifically, a plurality of second through holes 2424 are formed on the main body 2421;
[0070] In the above solution, the second through hole 2424 is opened on the main body 2421, which can further improve the movable direction of the raw materials and accelerate the mixing of the raw materials.
[0071] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.
[0072] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application are within the scope of the technical solution of the present application.
