Description

Technical Field

[0001] This invention relates to the field of non-standard storage tank technology, specifically to a non-standard storage tank structure and construction method for precise temperature control. Background Technology

[0002] Precision temperature-controlled non-standard storage tanks are specially designed for storing and transporting materials in a specific temperature environment. Compared with ordinary non-standard storage tanks, precision temperature-controlled non-standard storage tanks have stronger temperature control and insulation functions, which can ensure that the internal temperature remains stable under different environmental and climatic conditions, so that the materials stored inside are always within the set ideal temperature range. This is especially important for some pharmaceuticals, chemicals, biological products and other materials that require a specific temperature environment to maintain the stability of the substances.

[0003] Different types of materials have different temperature requirements and need to be maintained in a specific temperature environment to maintain stability. Therefore, in actual storage, it is necessary to accurately control the storage temperature. As the storage volume increases, the heat capacity of the storage tank will also increase accordingly. This will lead to more drastic temperature fluctuations inside the storage tank, forming areas with uniform or uneven heat distribution. This will affect the temperature distribution inside the storage tank and make it difficult to accurately control the temperature inside the storage tank. In order to accurately control the temperature of the materials inside the storage tank, the existing technology generally divides the storage tank into multiple zones, and each zone uses an independent control system for precise temperature control. This can reduce the temperature fluctuations inside the entire storage tank and improve the temperature control accuracy. However, since each zone requires an independent control system, this increases the difficulty of management and control. Furthermore, since the temperature control of each zone is independent, local temperature unevenness may occur in some zones, causing damage to the stored materials. Summary of the Invention

[0004] This invention proposes a non-standard storage tank structure and construction method for precise temperature control, which solves the problem in related technologies that makes it difficult to accurately control the temperature of substances in the storage tank due to uneven temperature in different areas of the tank.

[0005] The technical solution of the present invention is as follows: A non-standard storage tank structure with precise temperature control includes the tank body and also includes: The storage tank body has three fixed cylinders fixedly installed at equal angles, and the angle between the three fixed cylinders and the axis of the storage tank body is 45°.

[0010] Based on the aforementioned solution, the heating component includes: A support plate, which is rotatably mounted on the lower part of the storage tank; A heater, which is fixedly mounted on the support plate; A heat pipe is rotatably installed inside the storage tank and is fixedly connected to the support plate; The heat-conducting pipe has multiple connecting pipes that are symmetrically connected at equal intervals. A heat-conducting wire is fixedly installed on the heater and is located inside the connecting pipe and the heat-conducting pipe.

[0011] Based on the aforementioned scheme, the heat equalization section includes: A third motor is fixedly installed on the storage tank; The first gear is fixedly installed at the output end of the third motor; The second gear is fixedly mounted on the bearing plate and meshes with the first gear.

[0014] A construction method for a precision temperature-controlled non-standard storage tank, comprising the aforementioned precision temperature-controlled non-standard storage tank structure, and further comprising the following steps: S1. Design: Draw a layout diagram based on the specific requirements of the storage tank body; S2. Processing: Cut the board material according to the design requirements and roll it into shape. S3. Inspection: Inspect the formed sheet material. Use a straight template in the vertical direction and an arc template in the horizontal direction. S4. Rolling: The plate is rolled into an arc shape using a rolling machine on a special platform. S5. Forming: The rolled plates are welded to form the tank body, and the joints of the tank body are tested for leaks. S6. Installation: Install the three fixed cylinders at equal angles onto the tank body, with the included angle between the three fixed cylinders being 120°. S7. Assemble the mixing equipment, install the mixing rod and the first motor on the three fixed cylinders in sequence, and arrange the axis of the mixing rod at 45° with the inner wall of the storage tank body; S8. Install the heat tracing half-pipe. The heat tracing half-pipe is installed on the tank body and is fully penetrated and welded to the inside of the tank body using a T-type weld. S9. Thermal insulation construction: The insulation layer and the protective layer are installed on the tank body in sequence from the inside to the outside.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the three stirring rods are arranged at a 120° angle, and the three stirring rods are at a 45° angle to the axis of the storage tank body. During the stirring process, the three stirring rods drive the corresponding stirring blades to move, thereby stirring the material, disrupting the flow of material at different heights, generating turbulence, and making the material flow vertically, thereby improving the temperature uniformity of the material in different areas.

[0016] 2. In this invention, the rotation of the stirring blades creates a negative pressure in the upper part of the outer shell, drawing external materials into the shell through the feed chute. Then, the rotation of the stirring blades discharges the materials through the discharge chute. Since the outer shell has three equal angles and the discharge chute is arranged at an incline, the materials discharged through the discharge chute will flow within the tank body and be affected by the materials flowing out of the discharge chute on other outer shells. This quickly and evenly distributes the materials in the tank body and reduces the impact of prolonged stirring on the materials.

[0017] 3. In this invention, the second motor drives the drive gear to rotate, and the drive gear drives the gear ring to rotate through the intermediate gear. The rotation of the gear ring drives the transmission cylinder to rotate, thereby driving the stirring frame to rotate. The stirring frame and the transmission rod rotate in opposite directions. When the material enters the stirring frame and is discharged from the through slot, the continuous rotation of the stirring frame drives the baffle plate to rotate. Through the cooperation of the baffle plate and the through slot, the material can be stirred by the flow of the material, thereby further improving the temperature uniformity of each area in the material and reducing the problems that may be caused by over-stirring.

[0018] 4. In this invention, the third motor drives the second gear to rotate via the first gear, thereby driving the bearing plate to rotate, which in turn drives the connecting pipe to rotate via the heat-conducting pipe. The inclined plate, in conjunction with the connecting pipe, stirs the heat-conducting medium in the storage tank, making the temperature of the heat-conducting medium in the storage tank more uniform. The temperature of the heat-conducting medium is monitored in real time by the first sensor until the heat-conducting medium reaches a suitable temperature, thereby making the heat distribution of the heat-conducting medium in the storage tank more uniform, reducing the occurrence of temperature fluctuations in the discharged heat-conducting medium, and making the temperature of the heat-conducting medium more controllable.

[0019] 5. In this invention, by setting up the uniform material assembly and the stirring assembly, when controlling the temperature of the material in the storage tank body through the heat tracing half-pipe, the possibility of different temperatures in different areas of the material is avoided, thereby improving the accuracy of temperature control. With the cooperation of the heat exchange assembly, the material is always kept at the required storage temperature, and the uniformity of the material is improved. With the setting of the heating assembly, not only can the heat transfer medium be heated uniformly, but also, in conjunction with the heat exchange assembly, the material in the storage tank body can be controlled more accurately and stably.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1 like Figures 1 to 11As shown, this embodiment proposes a non-standard storage tank structure for precise temperature control, including a storage tank body 1, a fixed cylinder 2, a material homogenizing assembly, a mounting frame 3, a stirring assembly, a storage tank 4, a heat tracing half-pipe 5, a heating assembly, and a heat exchange assembly. Three fixed cylinders 2 are fixedly installed at equal angles on the storage tank body 1, with each of the three fixed cylinders 2 forming a 45° angle with the axis of the storage tank body 1. The material homogenizing assembly is installed inside the fixed cylinders 2 to homogenize the material within the storage tank body 1. The material homogenizing assembly includes a fixed tube 6, a stirring rod 7, a first motor 8, and a material homogenizing section. The fixed tube 6 is fixedly installed at the bottom of each of the three fixed cylinders 2, and the stirring rod 7 is rotatably installed on each of the three fixed cylinders 2. The stirring rod 7 rotatably engages with the fixed tube 6. The first motor 8 is fixedly installed at the top of each of the three fixed cylinders 2, and the output end of the first motor 8 is fixedly connected to the stirring rod 7. A material homogenizing section is installed at the bottom of the fixed tube 6 to homogenize the temperature of different areas of the material.

[0025] Specifically, when storing materials such as pharmaceuticals, chemicals, and biological products that require a specific temperature environment to maintain material stability, first select a storage tank body 1 of appropriate capacity according to the amount of material, and install the storage tank body 1 in the working position. Then, fix three fixed cylinders 2 at equal angles to the storage tank body 1, with the axis of each fixed cylinder 2 forming a 45° angle with the inner wall of the storage tank body 1. Then, install the fixed pipe 6, stirring rod 7, and first motor 8 in sequence. Then, weld the heat tracing half-pipe 5 to the inside of the storage tank body 1 using a T-shaped weld. The heat tracing half-pipe 5 is generally arranged in 4 to 6 turns. After the storage tank body 1 is installed and passes inspection, the material to be stored can be poured into the storage tank body 1. To ensure that the temperature of each area of ​​the material is uniform, when the temperature of the material is lower than the required storage temperature, the heating component is activated to heat the heat transfer medium, and then the heat transfer medium is sent into the storage tank body 1 through the heat exchange component. The heating half-pipe 5 heats the material inside the storage tank body 1. To improve the temperature uniformity of the material in different areas, the first motor 8 is started. The first motor 8 drives the stirring rod 7 to rotate, which in turn drives the uniform material unit to rotate. The uniform material unit stirs the material. Since the three stirring rods 7 are arranged at a 120° angle and at a 45° angle to the axis of the storage tank body 1, during the stirring process, the three stirring rods 7 drive the corresponding uniform material unit to move, thereby stirring the material, disrupting the flow of material at different heights, generating turbulence, and causing the material to flow vertically, thus improving the temperature uniformity of the material in different areas. The stirring components stir the material synchronously until the material reaches the set temperature. In order to further maintain the temperature of the material and facilitate precise control of the storage temperature, an insulation layer is also added to the outside of the storage tank body 1.

[0026] Among them, such as Figure 4 , Figure 5As shown, the material mixing unit includes a shell 9, stirring blades 10, a feed trough 11, and a discharge trough 12. The shell 9 is fixedly installed at the bottom of the three fixed pipes 6, and the stirring blades 10 are fixedly installed at the bottom of the three stirring rods 7. Multiple feed troughs 11 are opened at equal angles on the shell 9, and the feed troughs 11 are located on the upper part of the stirring blades 10. Multiple discharge troughs 12 are opened at equal angles on the shell 9, and the discharge troughs 12 are located on the lower part of the stirring blades 10.

[0027] Specifically, as the stirring rod 7 rotates, it drives the stirring blade 10 to rotate. The rotation of the stirring blade 10 creates a negative pressure in the space above the outer shell 9, drawing external materials into the interior of the outer shell 9 through the feed chute 11. Then, through the rotation of the stirring blade 10, the materials are discharged through the discharge chute 12. Since the outer shell 9 has three equal angles and the discharge chute 12 is arranged at an incline, the materials discharged through the discharge chute 12 will flow inside the storage tank body 1 and be affected by the materials flowing out of the discharge chute 12 on other outer shells 9. This quickly and evenly distributes the materials in the storage tank body 1 and reduces the impact of prolonged stirring on the materials.

[0028] like Figures 6 to 8 As shown, the mounting frame 3 is fixedly installed at the bottom of the storage tank body 1, and the stirring assembly is installed on the mounting frame 3 for stirring the material inside the storage tank body 1. The stirring assembly includes a stirring frame 13, a transmission cylinder 14, a second motor 15, a transmission rod 16, an impeller 17, and a stirring part. The stirring frame 13 is rotatably installed on the inner bottom wall of the storage tank body 1, the transmission cylinder 14 is rotatably installed at the bottom of the storage tank body 1, and the transmission cylinder 14 is fixedly connected to the stirring frame 13. The second motor 15 is fixedly installed on the mounting frame 3, the transmission rod 16 is rotatably installed on the transmission cylinder 14, and the transmission rod 16 is rotatably connected to the stirring frame 13. The transmission rod 16 is fixedly connected to the output end of the second motor 15. The impeller 17 is fixedly installed at the top of the transmission rod 16 and is located inside the stirring frame 13. The stirring part is installed on the transmission cylinder 14 for driving the stirring frame 13 to stir the material.

[0029] Specifically, while uniformly heating the material in different areas of the storage tank 1, the second motor 15 is started to further improve working efficiency. The second motor 15 drives the transmission cylinder 14 to rotate through the stirring part, which in turn drives the stirring frame 13 to rotate. Through the setting of the stirring part, the transmission rod 16 is driven to rotate in the opposite direction, thereby driving the impeller 17 to rotate, creating a negative pressure area on the upper part of the stirring frame 13. This draws the material from top to bottom into the stirring frame 13 and discharges it from the through groove 21, ensuring that the material in the storage tank 1 is always kept tumbling to a certain extent, making the temperature of the material more uniform and facilitating real-time observation of the material temperature.

[0030] The above, such as Figure 7 , Figure 8As shown, the stirring section includes a gear ring 18, a drive gear 19, an intermediate gear 20, a through groove 21, and a baffle plate 22. The gear ring 18 is fixedly installed inside the transmission cylinder 14, the drive gear 19 is fixedly installed on the transmission rod 16, and the intermediate gear 20 is rotatably installed on the mounting bracket 3. The intermediate gear 20 meshes with the drive gear 19 and the gear ring 18. Multiple through grooves 21 are opened at equal angles on the stirring frame 13, and multiple baffle plates 22 are fixedly installed at equal angles on the stirring frame 13. The multiple baffle plates 22 and the multiple through grooves 21 are arranged alternately.

[0031] Specifically, while the second motor 15 drives the transmission rod 16 to rotate, the second motor 15 also drives the drive gear 19 to rotate. The drive gear 19 drives the intermediate gear 20 to rotate, which in turn drives the gear ring 18 to rotate. The rotation of the gear ring 18 drives the transmission cylinder 14 to rotate, which in turn drives the stirring frame 13 to rotate. The stirring frame 13 rotates in the opposite direction to the transmission rod 16. When the material enters the stirring frame 13 and is discharged from the through groove 21, the continuous rotation of the stirring frame 13 drives the baffle 22 to rotate. Through the cooperation of the baffle 22 and the through groove 21, the material can be stirred by the flow of the material, while reducing the problems that may be caused by over-stirring.

[0032] like Figures 9 to 11 As shown, the storage tank 4 is fixedly installed on the storage tank body 1, and the heat tracing half-pipe 5 is fixedly installed inside the storage tank body 1. The output end of the heat tracing half-pipe 5 is connected to the storage tank 4. The heating component is installed inside the storage tank 4 and is used to heat the heat transfer medium. The heating component includes a support plate 23, a heater 24, a heat transfer pipe 25, a connecting pipe 26, a heat transfer wire 27, and a heat equalization part. The support plate 23 is rotatably installed on the lower part of the storage tank 4. The heater 24 is fixedly installed on the support plate 23. The heat transfer pipe 25 is rotatably installed inside the storage tank 4 and is fixedly connected to the support plate 23. Multiple connecting pipes 26 are symmetrically connected to the heat transfer pipe 25 at equal intervals. The heat transfer wire 27 is fixedly installed on the heater 24 and is located inside the connecting pipe 26 and the heat transfer pipe 25. The heat equalization part is installed on the storage tank 4 and is used to equalize the temperature of the heat transfer medium.

[0033] Specifically, when heating the heat transfer medium, the heater 24 is activated to heat the heating wire, which in turn heats the heat transfer pipe 25 and the connecting pipe 26. This heats the medium to the set temperature through the heat transfer pipe 25 and the connecting pipe 26. By setting up the heat equalization section, the heat distribution of the heat transfer medium in the storage tank 4 can be made more uniform, preventing temperature fluctuations in the discharged heat transfer medium and making the temperature of the heat transfer medium more controllable, thereby improving the controllability of the material temperature in the storage tank body 1.

[0034] The above, such as Figure 10 , Figure 11 As shown, the heat equalization section includes a third motor 28, a first gear 29, a second gear 30, an inclined plate 31, and a first sensor 32. The third motor 28 is fixedly mounted on the storage tank 4, the first gear 29 is fixedly mounted on the output end of the third motor 28, the second gear 30 is fixedly mounted on the support plate 23, and the second gear 30 meshes with the first gear 29. Multiple inclined plates 31 are fixedly mounted at equal intervals on multiple connecting pipes 26, and the multiple inclined plates 31 are arranged alternately. The first sensor 32 is fixedly mounted on the storage tank 4.

[0035] Specifically, when heating the heat-conducting medium in storage tank 4, in order to make the temperature of each part of the medium more uniform and reduce the inconsistency of the temperature of the heat-conducting medium delivered out, the third motor 28 is started. The third motor 28 drives the first gear 29 to rotate, the first gear 29 drives the second gear 30 to rotate, and the second gear 30 drives the bearing plate 23 to rotate, which in turn drives the connecting pipe 26 to rotate through the heat-conducting pipe 25. With the setting of the inclined plate 31, the heat-conducting medium in storage tank 4 is stirred in conjunction with the connecting pipe 26, so that the temperature of the heat-conducting medium in storage tank 4 is more uniform. The temperature of the heat-conducting medium is monitored in real time by the first sensor 32. When the heat-conducting medium reaches a suitable temperature, the heater 24 can be turned off.

[0036] like Figure 9 As shown, the heat exchange assembly is installed on the storage tank 4 and is used to send the heat transfer medium into the heat tracing half pipe 5. The heat exchange assembly includes a first valve 33, a second valve 34 and a second sensor 35. The first valve 33 is fixedly installed at the input end of the heat tracing half pipe 5, the second valve 34 is fixedly installed at the output end of the heat tracing half pipe 5 and the second sensor 35 is fixedly installed on the storage tank body 1.

[0037] Specifically, after adjusting the temperature of the heat transfer medium, it is necessary to send the heat transfer medium into the heat tracing half-pipe 5 to heat or cool the material in the storage tank body 1. At this time, the first valve 33 and the second valve 34 are opened simultaneously, and the second sensor 35 is activated to detect the material temperature in the storage tank body 1 in real time. Then, the heat transfer medium is sent into the heat tracing half-pipe 5, and the material temperature in the storage tank body 1 can be adjusted through the heat transfer medium in the heat tracing half-pipe 5.

[0038] The above, such as Figure 9 As shown, the system includes a cooler 36, a water pump 37, a discharge pipe 39, and a third sensor 40. The water pump 37 is fixedly installed on the storage tank 4. The output end of the water pump 37 is connected to the first valve 33 through the discharge pipe 38. The discharge pipe 39 is connected between the input end of the water pump 37 and the storage tank 4. The third sensor 40 is fixedly installed on the discharge pipe 38. The cooler 36 is fixedly installed on the storage tank 4, and the discharge pipe 39 is located inside the cooler 36.

[0039] Specifically, the water pump 37 is started, and the water pump 37 draws the heat transfer medium from the storage tank 4 through the discharge pipe 39, and then sends the heat transfer medium into the discharge pipe 38. The temperature of the heat transfer medium flowing out of the discharge pipe 38 is monitored in real time by the setting of the third sensor 40, and finally discharged into the heat tracing half pipe 5, thereby controlling the material temperature in the storage tank body 1 through the heat transfer medium in the heat tracing pipe.

[0040] Further explanation is needed: the first sensor 32 monitors the temperature of the heat-conducting medium inside the storage tank 4 in real time; the second sensor 35 monitors the temperature of the material inside the storage tank body 1 in real time; and the third sensor 40 monitors the temperature of the heat-conducting medium entering the discharge pipe 38. When the temperature of the material poured into the storage tank body 1 is lower than the required storage temperature, the heat-conducting medium inside the storage tank 4 needs to be heated until its temperature rises slightly above the required storage temperature. Then, the heat-conducting medium is sent into the heating half-pipe 5 to heat the material until it approaches the required storage temperature, at which point the heating of the storage tank is stopped. The heat transfer medium in tank 4 can be heated. When the temperature of the material poured into the storage tank body 1 is higher than the required storage temperature, the heating of the heat transfer medium in the storage tank 4 is stopped. At this time, the cooler 36 is started to cool the heat transfer medium entering the discharge pipe 39 until it is slightly lower than the required storage temperature of the material. At the same time, the temperature of the heat transfer medium entering the heat tracing half pipe 5 through the discharge pipe 38 is detected in real time by the third sensor 40. When the temperature of the material in the storage tank body 1 is close to the required storage temperature, the cooler 36 can be stopped. Through the cooperation between the first sensor 32, the second sensor 35 and the third sensor 40, the precise temperature control of the material in the storage tank body 1 is achieved.

[0041] In summary, when storing materials such as pharmaceuticals, chemicals, and biological products that require a specific temperature environment to maintain material stability, first select a storage tank body 1 of appropriate capacity according to the amount of material, and install the storage tank body 1 in the working position. Then, fix three fixed cylinders 2 at equal angles on the storage tank body 1, with the axis of each fixed cylinder 2 forming a 45° angle with the inner wall of the storage tank body 1. Then, install the fixed pipe 6, stirring rod 7, and first motor 8 in sequence. Then, weld the heat tracing half-pipe 5 inside the storage tank body 1 using a T-shaped weld. The heat tracing half-pipe 5 is generally arranged in 4 to 6 turns. After the storage tank body 1 is installed and passes the inspection, the material to be stored can be poured into the storage tank body 1.

[0042] To ensure consistent temperature across all areas of the material, when there is a difference between the material's temperature and the required storage temperature, the temperature of the heat transfer medium needs to be adjusted first. When heating the heat transfer medium, heater 24 is activated to heat the heating wire, which in turn heats the heat transfer pipe 25 and connecting pipe 26. This, through the arrangement of heat transfer pipe 25 and connecting pipe 26, heats the material to the set temperature. To further evenly distribute the heat within the storage tank 4, reduce temperature fluctuations in the discharged heat transfer medium, and make the temperature of the heat transfer medium more controllable, the third motor 28 is activated. The third motor 28 drives the first gear 29 to rotate, which in turn drives the second gear 30 to rotate. The second gear 30 then drives the bearing plate 23 to rotate, which in turn drives the connecting pipe 26 to rotate via the heat-conducting pipe 25. The inclined plate 31, in conjunction with the connecting pipe 26, stirs the heat-conducting medium in the storage tank 4, making the temperature of the heat-conducting medium in the storage tank 4 more uniform. The temperature of the heat-conducting medium is monitored in real time by the first sensor 32. Once the heat-conducting medium reaches a suitable temperature, the heater 24 can be turned off, thus improving the controllability of the material temperature in the storage tank body 1.

[0043] After adjusting the temperature of the heat transfer medium, it is necessary to send the heat transfer medium into the heat tracing half-pipe 5 to heat or cool the material in the storage tank body 1. The water pump 37 is started, and the water pump 37 draws the heat transfer medium from the storage tank 4 through the discharge pipe 39, and then sends the heat transfer medium into the discharge pipe 38. At the same time, the first valve 33 and the second valve 34 are opened, and the second sensor 35 is activated to detect the temperature of the material in the storage tank body 1 in real time. Meanwhile, the temperature of the heat transfer medium flowing out of the discharge pipe 38 is monitored in real time through the setting of the third sensor 40. Finally, it is discharged into the heat tracing half-pipe 5, thereby controlling the temperature of the material in the storage tank body 1 through the heat transfer medium in the heat tracing pipe.

[0044] To improve the temperature uniformity of the material in different areas, the first motor 8 is started, which drives the stirring rod 7 to rotate. As the stirring rod 7 rotates, it drives the stirring blade 10 to rotate. The rotation of the stirring blade 10 creates a negative pressure in the upper space of the outer shell 9, drawing the external material into the outer shell 9 through the feed chute 11. Then, through the rotation of the stirring blade 10, the material is discharged through the discharge chute 12. Since the outer shell 9 has three equal angles and the discharge chute 12 is arranged at an angle, the material discharged through the discharge chute 12 will remain inside the storage tank body 1. The material flows and is affected by the material flowing out of the discharge trough 12 on the other outer shell 9, quickly and evenly distributing the material in the storage tank body 1, and reducing the impact of long-term stirring on the material. Since the three stirring rods 7 are arranged at a 120° angle and the three stirring rods 7 are at a 45° angle with the axis of the storage tank body 1, during the stirring process, the three stirring rods 7 drive the corresponding stirring blades 10 to move, thereby stirring the material, disrupting the flow of material at different heights, generating turbulence, and making the material flow vertically, thereby improving the temperature uniformity of the material in each area.

[0045] While uniformly heating the material in all areas of the storage tank 1, to further improve work efficiency, the second motor 15 is started. The second motor 15 drives the transmission rod 16 to rotate, which in turn drives the impeller 17 to rotate, creating a negative pressure area on the upper part of the stirring frame 13. This draws the material from top to bottom into the stirring frame 13, and then discharges it through the channel 21, ensuring that the material in the storage tank 1 is always kept tumbling to a certain extent, making the temperature of the material in all areas more uniform. At the same time that the second motor 15 drives the transmission rod 16 to rotate, the second motor 15 also drives the drive gear 19 to rotate. The drive gear 19 drives the intermediate gear 20 to rotate, which in turn drives the gear ring. The gear ring 18 rotates, which in turn drives the transmission cylinder 14 to rotate, thereby driving the stirring frame 13 to rotate. The stirring frame 13 rotates in the opposite direction to the transmission rod 16. When the material enters the stirring frame 13 and is discharged from the through groove 21, the continuous rotation of the stirring frame 13 drives the baffle 22 to rotate. Through the cooperation of the baffle 22 and the through groove 21, the material can be stirred by the flow of the material, while avoiding the problems that may be caused by over-stirring. It is convenient to observe the material temperature in real time. When the material reaches the set temperature, and in order to further maintain the temperature of the material and facilitate precise control of the storage temperature of the material, an insulation layer needs to be added to the outside of the storage tank body 1.

[0046] Example 2 Based on Example 1, this example also discloses a construction method for a precision temperature-controlled non-standard storage tank, which uses the aforementioned precision temperature-controlled non-standard storage tank structure and includes the following steps: The first step is design, which involves drawing a layout diagram based on the specific requirements of the storage tank body 1; The second step is processing, which involves cutting the boards according to the design requirements and rolling them into shape. Among them, the local unevenness after material cutting should not exceed 1% of the deformation length, the cutting surface should be smooth, and there should be no defects such as slag inclusions, delamination, cracks and molten slag. The third step is inspection. The formed boards are inspected using a straight template in the vertical direction and an arc template in the horizontal direction. The fourth step is rolling. A rolling machine is used to roll the board into an arc shape on a special platform. When rolling, attention must be paid to the direction of the bevel of the board. The fifth step is forming. The rolled plates are welded to form the tank body 1. Soap water is applied to the joints of the tank body 1 to test for leaks. If there is no leakage, it is considered qualified. Step 6, Installation: Install the three fixed cylinders 2 at equal angles onto the tank body 1, with the included angle between the three fixed cylinders 2 being 120°. The fixed cylinder 2 is located at 4 / 5 of the height of the tank body 1; Step 7: Assemble the mixing equipment. Install the mixing rod 7 and the first motor 8 on the three fixed cylinders 2 in sequence. The axis of the mixing rod 7 is arranged at 45° with the inner wall of the tank body 1. During the mixing process, the flow of materials at different heights is disrupted to generate turbulence, thereby improving the temperature uniformity of different areas of the material. Step 8: Install the heat tracing half-pipe 5. The heat tracing half-pipe 5 is set on the tank body 1. The heat tracing half-pipe 5 is fully penetrated and welded to the inside of the tank body 1 using a T-type weld. The welding quality is tested using a vacuum test. Among them, the heat tracing half-pipe 5 is generally arranged in 4 to 6 turns; Step 9: Insulation construction. On the main body of the storage tank 1, the insulation layer and the protective layer are installed in sequence from the inside out.
