Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel heating technology, and in particular relates to a reaction vessel heating device. Background Technology

[0002] A reactor heating device is a device used to heat the materials inside a reactor. It mainly transfers heat to the materials inside the reactor through an external heat source to control the reaction temperature, thereby affecting the rate and efficiency of the chemical reaction. Common reactor heating methods include electric heating, steam heating, and heat transfer oil heating. Specific applications include the synthesis of concrete water-reducing agents, which involves heating the reactants to a certain temperature to carry out a polymerization reaction.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing reactor heating devices:

[0004] 1. The heating tube is a single spiral type, which easily leads to a temperature difference between the inlet and outlet, resulting in uneven heating. It is not convenient to compensate for the temperature difference by introducing liquid in opposite directions through two spiral heating tubes.

[0005] 2. The heating tube is welded to the outer circumference of the reactor, which makes it impossible to disassemble and replace the heating tube after it is damaged. It is also inconvenient to fix the heating tube to the outside of the reactor through a fixing structure. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a reactor heating device to address the issues that existing heating tubes are single-tube spiral type, which easily leads to temperature differences between the inlet and outlet, resulting in uneven heating, and it is inconvenient to compensate for the temperature difference by introducing liquid in opposite directions through two spiral heating tubes; the heating tubes are welded to the outer circumference of the reactor, making it impossible to disassemble and replace the heating tubes after damage, and it is inconvenient to fix the heating tubes to the outside of the reactor through a fixing structure.

[0007] The purpose and effectiveness of this novel reactor heating device are achieved through the following specific technical means:

[0008] A heating device for a reaction vessel includes a heating device body. The heating device body is provided with an upper liquid inlet heating pipe in a vertical direction. The upper liquid inlet heating pipe has a spiral tubular structure. A downward-facing long L-shaped liquid inlet pipe is provided on the upper left side of the upper liquid inlet heating pipe. A threaded annular groove is formed on the outer circumference of the lower end of the long L-shaped liquid inlet pipe. An upward-facing short L-shaped liquid outlet pipe is provided on the lower right side of the upper liquid inlet heating pipe. A threaded annular groove is formed on the outer circumference of the upper end of the short L-shaped liquid outlet pipe. A lower liquid inlet heating pipe in a vertical direction is fitted onto the upper liquid inlet heating pipe. The lower liquid inlet heating pipe has a spiral tubular structure. An upward-facing short L-shaped liquid outlet pipe is formed on the lower left side of the lower liquid inlet heating pipe. The upper part of the short L-shaped inlet pipe of the lower inlet heating pipe has a threaded annular groove on the outer circumference of the upper end. The lower part of the long L-shaped outlet pipe of the lower inlet heating pipe has a threaded annular groove on the outer circumference of the lower end. A vertical pipe assembly tee is installed between the long L-shaped inlet pipe of the upper inlet heating pipe and the short L-shaped inlet pipe of the lower inlet heating pipe. A vertical pipe assembly tee is installed between the short L-shaped outlet pipe of the upper inlet heating pipe and the long L-shaped outlet pipe of the lower inlet heating pipe. The three ends of the pipe assembly tee have threaded annular grooves on the inner circumference of the three ends. The three ends of the pipe assembly tee have regular hexagonal ring plates on the outer circumference of the three ends.

[0009] Furthermore, an assembly limiting cylinder in the front-to-back direction is installed inside the threaded hole of the heat-insulating half cylinder, a threaded post is provided at the inner end of the assembly limiting cylinder, and a regular hexagonal prism is provided on the outer end face of the threaded post of the assembly limiting cylinder.

[0010] Furthermore, each end of the heat-insulating half-cylinder is equipped with an assembly locking hoop on its outer circumference. The inner circumference of the assembly locking hoop is threaded, and the outer circumference of the assembly locking hoop is provided with eight vertically penetrating rotating grooves in an annular array.

[0011] Furthermore, a fitting semi-circular groove is provided in the middle of the inner circumference of the heat-insulating half-cylinder, and fitting grooves that run through the left and right are provided at both the upper and lower ends of the inner end face of the heat-insulating half-cylinder. Threaded holes that run through the front and back are provided at both the upper and lower ends of the heat-insulating half-cylinder.

[0012] Furthermore, the upper liquid inlet heating pipe is provided with heat-insulating half-cylinders in the vertical direction at both the front and rear, and the outer circumference of the upper and lower ends of the heat-insulating half-cylinders is provided with threaded semi-annular grooves.

[0013] Furthermore, a reactor protective shell is placed inside the upper liquid inlet heating pipe, and insertion blind holes are opened on the front and back of the outer circumference of both the upper and lower ends of the reactor protective shell.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The liquid for heating is designed to flow downwards from the top of the upper inlet heating tube and upwards from the bottom of the lower inlet heating tube. This complementary flow ensures more uniform heating and solves the problem that a single spiral heating tube can easily cause temperature differences between the inlet and outlet, resulting in uneven heating and making it inconvenient to compensate for the temperature difference by introducing liquid in opposite directions through two spiral heating tubes.

[0016] The convenient heat-insulating half-cylinder protects the upper and lower liquid inlet heating pipes by assembling and locking the circular hoop. The convenient heat-insulating half-cylinder is installed on the outside of the reactor's protective shell by assembling the limiting cylinder, which allows for easy assembly and disassembly. This solves the problem that the heating pipes are welded to the outside circumference of the reactor, making it impossible to disassemble and replace them after damage, and that it is inconvenient to fix the heating pipes to the outside of the reactor through a fixing structure.

[0025] Example 1:

[0026] As attached Figure 1 To be continued Figure 6 As shown:

The long L-shaped inlet pipe of the upper inlet heating pipe 2 and the lower inlet... A vertically oriented pipe assembly tee 4 is installed between the short L-shaped inlet pipes of the liquid heating tube 3 to facilitate connection with an external liquid inlet pipe. A vertically oriented pipe assembly tee 4 is installed between the short L-shaped outlet pipe of the upper liquid inlet heating tube 2 and the long L-shaped outlet pipe of the lower liquid inlet heating tube 3 to facilitate connection with an external liquid outlet pipe. The pipe assembly tee 4 has threaded annular grooves on the inner circumference of its three ends to facilitate pipe installation via threads. The pipe assembly tee 4 has regular hexagonal ring plates on the outer circumference of its three ends to facilitate rotation and disassembly using tools.

[0028] The upper liquid inlet heating pipe 2 has a vertically oriented reactor protective shell 5 inside, which facilitates the support of various components. The reactor protective shell 5 has blind insertion holes on both the front and back of its outer circumference at both ends, facilitating the insertion of the positioning cylinder 8. The upper liquid inlet heating pipe 2 has vertically oriented heat-insulating half-cylinders 6 on both sides, facilitating heat insulation and protection for the upper and lower liquid inlet heating pipes 2 and 3. The heat-insulating half-cylinders 6 have threaded semi-annular grooves on both the front and back of their outer circumferences, facilitating the installation of the locking hoop 7 via threads. The heat-insulating half-cylinder 6 has a fitting semi-annular groove in the middle of its inner circumference, facilitating the placement of the upper and lower liquid inlet heating pipes 2 and 3 inside. The heat-insulating half-cylinder 6 has horizontally penetrating fitting grooves on both the front and back of its inner end face, facilitating the insertion of the L-shaped tubes of the upper and lower liquid inlet heating pipes 2 and 3, and providing heat insulation. Both ends of the heat-insulating half-cylinder 6 are provided with threaded holes that extend from front to back, facilitating the installation of the assembly limiting cylinder 8 via threads. Assembly locking hoops 7 are installed on the outer circumference of both ends of the heat-insulating half-cylinder 6, facilitating the assembly of the heat-insulating half-cylinder 6 into a cylindrical structure.

The outer end face of the threaded post of the assembly limiting cylinder 8 is provided with a regular hexagonal prism, facilitating rotational assembly and disassembly using tools.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In this utility model, such as Figure 1As shown, the reactor protective shell 5 is cut off at both ends. When the heating device body 1 is in use, the left-side pipe assembly tee 4 is connected to the external liquid inlet pipe, and the right-side pipe assembly tee 4 is connected to the external liquid outlet pipe. This allows heated liquid to enter the upper end of the upper liquid inlet heating pipe 2 and the lower end of the lower liquid inlet heating pipe 3 from the left-side pipe assembly tee 4. The heated liquid flows downwards from the upper end of the upper liquid inlet heating pipe 2 and upwards from the lower end of the lower liquid inlet heating pipe 3. The heat of the liquid is transferred to the reactor protective shell 5 through the upper and lower liquid inlet heating pipes 2 and 3. This method of counter-current liquid inlet from the two spiral heating pipes achieves temperature difference complementarity, making the reactor protective shell 5 more evenly heated, thereby improving the performance of the concrete water-reducing agent. The synthesis efficiency is improved, and the liquid that loses heat flows out from the right-side pipe assembly tee 4 to the external liquid outlet pipe, thus forming a circulation. When the reactor protective shell 5 is disassembled, the assembly limiting cylinder 8 is rotated with a tool to engage with the heat insulation half cylinder 6 threadedly, so that the assembly limiting cylinder 8 moves outward through the thread engagement and disengages from the insertion blind hole of the reactor protective shell 5. Then, the reactor protective shell 5 is pulled upward, thus realizing the disassembly of the reactor protective shell 5. The assembly locking hoop 7 is rotated with a tool to engage with the heat insulation half cylinder 6 threadedly, so that the assembly locking hoop 7 moves outward through the thread engagement and disengages from both ends of the heat insulation half cylinder 6, thus realizing the separation between the heat insulation half cylinders 6. This detachable installation method makes it convenient to disassemble and replace the heating components after they are damaged.

[0031] Example 2:

[0032] The difference from Embodiment 1 is that the regular hexagonal prism of the assembly limiting cylinder 8 can also be set as a regular heptagonal prism, thereby requiring a special tool that works with the regular heptagonal prism to rotate the assembly limiting cylinder 8, preventing non-staff members from rotating and disassembling the assembly limiting cylinder 8.

[0033] Example 3:

[0034] The difference from Embodiment 1 is that the inner end face of the assembly locking hoop 7 can also be set as a frosted surface, thereby increasing the friction between the inner end face of the assembly locking hoop 7 and the heat insulation half cylinder 6, and preventing the assembly locking hoop 7 from rotating and loosening.
