Description

Technical Field

[0001] This invention relates to the field of chemical production equipment technology, specifically to a chemical raw material reaction tank that allows materials to be heated uniformly. Background Technology

[0002] In chemical production, paraffin wax, as a commonly used raw material, needs to be heated to become liquid before participating in subsequent processes. Currently, for large-volume paraffin wax with regular shapes (such as cylinders or blocks), batch heating and liquefaction mainly relies on two technical solutions:

[0003] Firstly, reaction vessels with built-in flow guiding structures are used. These vessels utilize components such as stirring paddles and baffles to mechanically agitate the paraffin wax, resulting in more uniform heating and reducing localized overheating or unmelted areas. However, this approach has significant limitations: because paraffin wax is initially a large, regular block, its heat conduction path is long (especially in the central region). The flow guiding structure can only optimize heat transfer in liquid paraffin through physical agitation; it cannot shorten the heat transfer distance within solid paraffin wax. In actual production, even with uniform heating, the time for large-volume paraffin wax to completely liquefy from the surface to the center is still as long as 3-5 hours, resulting in low heating efficiency and difficulty in meeting the cycle time requirements of continuous industrial production.

[0004] Secondly, the paraffin wax undergoes pretreatment and cutting. Before heating, large volumes of paraffin wax are mechanically cut into smaller pieces, which are then placed in the tank for heating. While this method shortens the heat transfer path and increases the liquefaction rate (approximately 25% more efficient than the uncut state), it requires additional cutting equipment (such as a hydraulic cutter), increasing equipment investment and floor space. Furthermore, the cutting process requires separate manual operation, extending the production cycle (adding 15-20 minutes of pretreatment time per batch), resulting in limited overall production efficiency improvement. Summary of the Invention

[0005] In view of the above-mentioned defects in the existing technology, the present invention aims to solve the technical problem of "efficient and uniform heating without pretreatment cutting" in the heating and liquefaction process of large-volume regular paraffin wax. Specifically, it includes: how to simultaneously cut the paraffin wax during the heating process to shorten the heat transfer path, how to improve the heating uniformity through structural design, and how to avoid the cost increase caused by additional processes.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a chemical raw material reaction vessel for uniform heating of materials, comprising a fixed support platform and a reaction vessel with a heating function, wherein the reaction vessel is installed on the fixed support platform; a rotating structure and a transmission structure are respectively provided on both sides of the fixed support platform, wherein the working end of the rotating structure is located inside the reaction vessel, and the working end of the transmission structure is located inside the reaction vessel and is located inside the rotating structure;

[0007] The rotating structure is equipped with several sets of stirring structures, with each pair of stirring structures symmetrically distributed and spaced apart. Each set of stirring structures is connected to the transmission structure. The working end of the stirring structure is a sharp blade. The rotating structure can drive the stirring structure to rotate to move the paraffin wax. The transmission structure can drive the stirring structure to adjust its angle.

[0008] The reaction vessel is equipped with multiple blocking blocks, which are spaced apart. Every two blocking blocks are located on both sides of a set of stirring structures, at the top and left and right ends of the reaction vessel, without affecting the rotation of the stirring structures. The sharp blades of the stirring structures can cut paraffin wax. When the stirring structures move the paraffin wax, the blocking blocks can contact the paraffin wax to generate resistance and cooperate with the blades to cut the paraffin wax. The reaction vessel has a feed end at the top and a discharge end at the bottom. Both the feed end and the discharge end are connected to the reaction vessel through a sealing structure.

[0009] Furthermore, each of the blocking blocks has sharp corners at both ends.

[0010] Furthermore, the rotating structure includes a drive mounting frame, a drive power supply, a drive rod, and a rotating connecting rod. The drive mounting frame is located on one side of the fixed support platform, the drive power supply is mounted on the drive mounting frame, one end of the drive rod is connected to the output end of the drive power supply, the rod body passes through the side wall of the reaction tank through a bearing, and the other end is located inside the reaction tank and connected to one end of the rotating connecting rod. The other end of the rotating connecting rod is rotatably mounted on the inner wall of the reaction tank.

[0011] Furthermore, the rotating connecting rod is hollow inside, and the working end of the transmission structure is located inside the rotating connecting rod; the rotating connecting rod is provided with several hollow mounting shafts, and the interior of each mounting shaft is connected to the interior of the rotating connecting rod, and each set of stirring structures can be detachably installed on a mounting shaft.

[0012] Furthermore, the transmission structure includes a second drive mounting frame, a second drive power supply, a second drive rod, a transmission connecting rod, and a drive bevel gear. The second drive mounting frame is located on the other side of the fixed support platform. The second drive power supply is mounted on the second drive mounting frame. One end of the second drive rod is connected to the output end of the second drive power supply. The rod body passes through the side wall of the reaction tank through a bearing, and the other end is connected to the transmission connecting rod located inside the rotating connecting rod. The transmission connecting rod is provided with multiple spaced drive bevel gears, and each drive bevel gear is connected to two sets of symmetrical stirring structures.

[0013] Furthermore, the transmission connecting rod and the second drive rod are connected by a one-way bearing.

[0014] Furthermore, the stirring structure includes an assembly connecting rod, a rotating connecting sleeve, a rotating rod, a transmission bevel gear, and stirring blades; the assembly connecting rod is mounted on an installation shaft, the rotating connecting sleeve is rotatably sleeved on the assembly connecting rod, one end of the rotating rod is connected to the rotating connecting sleeve, and the other end passes through the assembly connecting rod and extends into the rotating connecting rod, the transmission bevel gear is mounted on the rotating rod end and meshes with the drive bevel gear, and the stirring blades are located on the side of the rotating connecting sleeve away from the assembly connecting rod and inside the reaction vessel.

[0015] Furthermore, the stirring blade is flat and has a bladed structure on one side.

[0016] Furthermore, the assembly connecting rod and the mounting shaft are connected by threads, and a sealing structure is provided between them.

[0017] Furthermore, in each pair of symmetrical stirring structures, the transmission bevel gears of the two stirring structures mesh with the two sides of the same driving bevel gear, and can rotate in opposite directions as the driving bevel gear rotates.

[0018] In summary, the present invention has the following main beneficial effects:

[0019] 1. Paraffin wax cutting without pretreatment, improving heating efficiency. This invention achieves this effect through the cooperation of a stirring structure and a blocking block: one side of the stirring blade of the stirring structure has an open edge, which can directly cut large volumes of paraffin wax in the reaction vessel when the entire structure rotates under the drive of the rotating structure; when the stirring blade is embedded in the paraffin wax without cutting it and moves the paraffin wax, the blocking block in the reaction vessel comes into contact with the paraffin wax and generates resistance, forming a shearing action with the open edge of the stirring blade, forcibly cutting the paraffin wax. At the same time, the sharp corner structure at both ends of the blocking block and the open edge structure of the stirring blade further enhance the shearing effect, decomposing large volumes of paraffin wax into smaller volumes without additional pretreatment cutting process, shortening the heat transfer path and significantly improving heating efficiency.

[0020] 2. Multi-angle adjustable stirring structure improves heating uniformity. This invention utilizes the cooperation between the transmission structure and the stirring structure: the drive bevel gear of the transmission structure meshes with the transmission bevel gear of the stirring structure. When the driving power source drives the transmission connecting rod to rotate, the drive bevel gear rotates through meshing, thereby driving the stirring blades to adjust their angle (from vertical to inclined plane and then to horizontal). Stirring blades at different angles can adapt to different states of paraffin wax from solid to liquid: expanding the cutting range in the solid stage and enhancing the mixing effect in the liquid stage; at the same time, the rotating structure drives the entire stirring structure to rotate, causing the paraffin wax to move within the reaction vessel, avoiding local overheating and ensuring uniform heating.

[0021] 3. The structural design is stable and reliable, reducing maintenance costs. This effect is achieved through the combination of the assembly structure and the one-way bearing: the mounting shaft of the stirring structure's assembly connecting rod and the rotating connecting rod are threaded together and equipped with a sealing structure, which facilitates the disassembly and maintenance of the stirring blades and ensures the sealing of the reaction vessel; in the transmission structure, the transmission connecting rod and the second drive rod are connected by a one-way bearing. When the rotating structure drives the stirring structure to rotate, the one-way bearing rotates freely, preventing the transmission connecting rod from driving the second drive power supply in the reverse direction, protecting the equipment from damage and extending its service life.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of the present invention will now be described.

[0034] Example 1

[0035] according to Figures 1-9 The chemical raw material reaction vessel shown includes a fixed support platform 1 placed on the ground and a reaction vessel 2 with heating function. The reaction vessel 2 is installed on the fixed support platform 1. A rotating structure 3 and a transmission structure 4 are respectively installed on both sides of the fixed support platform 1. The working end of the rotating structure 3 is located inside the reaction vessel 2, and the working end of the transmission structure 4 is located inside the rotating structure 3 while being inside the reaction vessel 2.

[0036] The rotating structure 3 is equipped with several sets of stirring structures 5. Each pair of stirring structures 5 is symmetrically installed on the rotating structure 3, and the stirring structures 5 are spaced apart. The stirring structures 5 are connected to the transmission structure 4 on the rotating structure 3. The working end of each stirring structure 5 is a sharp blade structure. The stirring structures 5 can be driven to rotate on the rotating structure 3. In this way, the stirring structures 5 can move the paraffin wax in the reaction tank 2 by rotating. This allows the paraffin wax to be heated evenly in the reaction tank 2 by moving. Furthermore, the transmission structure 4 can drive the stirring structures 5 in the rotating structure 3 to adjust the angle, so that the stirring structures 5 can be reversed from a single row, such as vertical or horizontal, thereby increasing the contact range between the stirring structures 5 and the paraffin wax.

[0037] Multiple blocking blocks 21 are installed in the reaction vessel 2, spaced apart from each other. Each pair of blocking blocks 21 is located on either side of a set of stirring structures 5. The blocking blocks 21 are positioned at the top and left / right ends of the reaction vessel 2, respectively. The blocking blocks 21 do not affect the normal rotation of the stirring structures 5 in the reaction vessel 2. Furthermore, because paraffin wax has a regular shape, it is located at the bottom of the reaction vessel 2. Therefore, when the stirring structure 5 rotates within the reaction vessel 2, it can cut the paraffin wax with its sharp working end. If the working end of the stirring structure 5 becomes embedded in the paraffin wax without cutting it off, it will instead cause the paraffin wax to be pulled further into the reaction vessel. When the wax is in a moving state, the blocking block 21 will play a cooperating role. The paraffin wax is driven to move on the working end of the stirring structure 5 and will come into contact with the blocking block 21 to generate resistance. In this way, the working end of the stirring structure 5 can cut off the paraffin wax. In this way, the paraffin wax can be cut off when it is heated and turned into a liquid state, thereby improving the working efficiency. Furthermore, when the paraffin wax is completely or mostly turned into a liquid state after being heated in the reaction tank 2, the reverse rotation of the working end of the stirring structure 5 can also stir the liquid paraffin wax evenly, so that the liquid paraffin wax is in a uniform heating state.

[0038] The upper and lower ends of the reaction vessel 2 are respectively provided with a feed end 22 and a discharge end 23, both of which are connected to the reaction vessel 2 by a sealed structure. The feed end 22 and the discharge end 23 allow the paraffin wax in a fixed state to enter the reaction vessel 2 and the paraffin wax in a liquid state to exit the reaction vessel 2, respectively.

[0039] Each blocking block 21 has sharp corners at both ends. When the blocking blocks 21 of this shape are used in conjunction with the working end of the stirring structure 5, they can interact with each other. On the one hand, the blocking blocks 21 can generate resistance to the paraffin wax, making it easier for the working end of the stirring structure 5 to cut it. On the other hand, the working end of the stirring structure 5 can also generate resistance, which, together with the sharp corners of the blocking blocks 21, can cut or slit the paraffin wax. This can further improve the efficiency of paraffin wax cutting and the heating efficiency of paraffin wax.

[0040] The rotating structure 3 includes a drive mounting frame 31, a drive power supply 32, a drive rod 33, and a rotating connecting rod 34. The drive mounting frame 31 is mounted on one side of the fixed support platform 1, and the drive power supply 32 is mounted on the drive mounting frame 31. One end of the drive rod 33 is connected to the working end of the drive power supply 32, and the rod body of the drive rod 33 is mounted on one side of the reaction tank 2 via a bearing. The other end of the drive rod 33 is located inside the reaction tank 2. One end of the rotating connecting rod 34 is connected to the other end of the drive rod 33, and the other end of the rotating connecting rod 34 is rotatably mounted in the reaction tank 2. The drive power supply 32 is mainly used to drive the drive rod 33 to rotate. The drive rod 33, in turn, can drive the rotating connecting rod 34 to rotate within the reaction tank 2 using the power of the drive power supply 32. In this way, the rotating connecting rod 34 can drive several sets of stirring structures 5 to rotate within the reaction tank 2.

[0041] The rotating connecting rod 34 is hollow inside, and the working end of the transmission structure 4 is located inside the rotating connecting rod 34. The rotating connecting rod 34 is provided with several mounting shafts 35, each of which is hollow and connected to the inside of the rotating connecting rod 34. Each mounting shaft 35 can detachably install a set of stirring structures 5 on the rotating connecting rod 34.

[0042] The transmission structure 4 includes a second drive mounting frame 41, a second drive power supply 42, a second drive rod 43, a transmission connecting rod 44, and a drive bevel gear 46. The second drive mounting frame 41 is set on the other side of the fixed support platform 1. The second drive power supply 42 is mounted on the second drive mounting frame 41. One end of the second drive rod 43 is connected to the working end of the second drive power supply 42. The rod body of the drive rod is mounted in the other side of the reaction tank 2 through a bearing. The transmission connecting rod 44 is located inside the rotating connecting rod 34 and is connected to the other end of the second drive rod 43. The transmission connecting rod 44 is provided with multiple spaced drive bevel gears 46. Each drive bevel gear 46 can be connected to two sets of symmetrically arranged stirring structures 5 inside the rotating connecting rod 34. The second driving power supply 42 is used to drive the second driving rod 43 to rotate. When the second driving rod 43 rotates, it enables the transmission connecting rod 44 to rotate inside the rotating connecting rod 34. When the transmission connecting rod 44 rotates, it enables multiple driving bevel gears 46 to rotate synchronously. When the multiple driving bevel gears 46 rotate, they enable several sets of stirring structures 5 to adjust their angles on the rotating connecting rod 34.

[0043] A one-way bearing 45 is installed on one end of the transmission connecting rod 44, and the transmission connecting rod 44 is connected to the drive rod 43 through the one-way bearing 45. The one-way bearing 45 is a type of bearing that can rotate freely in one direction and is locked in the other direction. In this design, when the drive rod 43 drives the transmission connecting rod 44 to rotate, the one-way bearing 45 is locked, which facilitates the drive rod 43 to drive the transmission connecting rod 44 to rotate. When the rotating connecting rod 34 drives the stirring structure 5 to rotate, since the stirring structure 5 and the transmission connecting rod 44 are connected by a bevel gear set, the transmission connecting rod 44 will also rotate. At this time, the one-way bearing 45 is in a free-rotating state, which can prevent the transmission connecting rod 44 from driving the drive rod 43 and causing the drive power supply 42 to reverse.

[0044] The stirring structure 5 includes an assembly connecting rod 51, a rotating connecting sleeve 52, a rotating rod 53, a transmission bevel gear 54, and a stirring blade 55. The assembly connecting rod 51 is mounted on the mounting shaft 35, and the rotating connecting sleeve 52 is rotatably mounted on the assembly connecting rod 51. One end of the rotating rod 53 is located on the rotating connecting sleeve 52, and the rotating rod 53 passes through the assembly connecting rod 51 and is located inside the mounting shaft 35 and the rotating connecting rod 34. The transmission bevel gear 54 is mounted on the other end of the rotating rod 53, and the transmission bevel gear 54 meshes with the drive bevel gear 46 inside the rotating connecting rod 34. The stirring blade 55 is located on the other side of the rotating connecting sleeve 52 and is located in the reaction vessel 2.

[0045] In this design, the assembly connecting rod 51 is used to rotate the connecting sleeve 52 onto the mounting shaft 35. The rotating connecting sleeve 52 is connected to the driving bevel gear 46 within the rotating connecting rod 34 via the rotating rod 53 and the transmission bevel gear 54. Thus, when the driving bevel gear 46 rotates, the transmission bevel gear 54 can drive the rotating rod 53 and the rotating connecting sleeve 52 mounted on the assembly connecting rod 51 to rotate. The rotating connecting sleeve 52 can then drive the stirring blade 55 to rotate, which facilitates the stirring blade 55 in disrupting and cutting the paraffin wax.

[0046] In this design, since each pair of stirring structures 5 are symmetrically arranged on both sides of the rotating connecting rod 34, the transmission bevel gear 54 in each pair of stirring structures 5 will mesh with the same driving bevel gear 46, and the two transmission bevel gears 54 will be located on both sides of a driving bevel gear 46 respectively. This assembly method will cause the two transmission bevel gears 54 to rotate clockwise and counterclockwise when the driving bevel gear 46 rotates clockwise. Under this rotation method, the two symmetrical stirring blades 55 will move in opposite directions to the left and right respectively. The advantage of this movement method is that it increases the contact range between the stirring blades 55 and the paraffin wax. Since the two blocking blocks 21 are spaced apart, and the stirring blades 55 will also pass through the gaps between the blocking blocks 21 when rotating, the way the two stirring blades 55 move apart without contacting the blocking blocks 21 can minimize the situation where the paraffin wax on the stirring blades 55 passes through the gaps between the two blocking blocks 21 when the stirring blades 55 are cutting the paraffin wax, causing the stirring blades 55 to be unable to cooperate with the blocking blocks 21 to cut the paraffin wax.

[0047] The assembly connecting rod 51 and the mounting shaft 35 are connected by a threaded connection, and a sealing structure is provided between them. The threaded connection between the assembly connecting rod 51 and the mounting shaft 35 allows for detachable installation, which ensures that the stirring blade 55 can be easily removed from the rotating connecting rod 34 for maintenance or replacement.

[0048] Each stirring blade 55 is flat and has a sharpened edge on one side, resembling a kitchen knife.

[0049] In this design, the stirring blade 55 can heat both solid and liquid paraffin, for example:

[0050] The first stage of paraffin heating: When using solid paraffin that has just begun heating, the stirring blades 55 are set vertically in the reaction vessel 2. When the stirring blades 55 rotate, they can work with the blocking block 21 to cut off the paraffin.

[0051] The second stage of paraffin heating: When using solid paraffin that has been cut multiple times, the paraffin changes from a regular shape to an irregular shape, and also changes from a single large volume to multiple smaller volumes. Therefore, the angle of the stirring blade 55 is adjusted by the operation of the transmission structure 4. The angle of the stirring blade 55 changes from a vertical state to an inclined state, which increases the range of movement of the stirring blade 55 between the two blocking blocks 21, so that the stirring blade 55 can contact more smaller volumes of paraffin and cooperate with the blocking blocks 21 to perform the cutting operation.

[0052] The third stage of paraffin heating: When using paraffin after most or all of it has been converted into a liquid state, the angle of the stirring blade 55 is adjusted to a horizontal state through the operation of the transmission structure 4. At this time, the stirring blade 55 can stir the liquid paraffin in a plate shape, so that the liquid paraffin is heated more evenly.
