Description

Technical Field

[0001] This utility model relates to a reaction vessel, and in particular to a large-capacity reaction vessel suitable for high-viscosity adhesive materials. Background Technology

[0002] Traditional reactors heat the material through their outer wall while an agitator stirs it internally to ensure uniform heating. However, for highly viscous materials, such as adhesives with a viscosity of 100,000 mPa·s, the volume of the stirred reactor must be very small to accommodate the high viscosity. Otherwise, the agitator would require enormous power, making it inefficient and uneconomical from an energy perspective. Furthermore, because the material in the reactor is highly viscous, the adhesion between the material and the reactor wall is strong. When the agitator stirs the material, it experiences significant resistance from the material. This resistance also acts on the motor base, which in turn acts on the reactor wall. This means the reactor wall must withstand enormous torque, requiring high mechanical strength and a thicker wall, which negatively impacts the reactor's cost.

[0003] When a large amount of material needs to be cast and coated per unit time, a large-capacity reactor is required to accommodate the continuous feeding of such high-viscosity materials. As explained above, traditional reactors are either too small to keep up with the material consumption or too expensive to manufacture, resulting in high production costs.

[0004] Therefore, a reactor was designed to meet the requirements of continuous coating of high-viscosity adhesive materials while also being economical, so as to realize the production needs of large-capacity continuous coating. Utility Model Content

[0005] The purpose of this invention is to provide a large-capacity reaction vessel suitable for high-viscosity adhesive materials, so as to solve the problem that existing reaction vessels cannot meet the needs of large-capacity high-viscosity adhesive production.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A large-capacity reaction vessel suitable for high-viscosity adhesive materials, including

[0008] The vessel body has a conical constriction at the bottom, the diameter of which gradually increases from bottom to top;

[0009] The outer wall heating tube A is spirally coiled around the outer surface of the converging part;

[0010] The inner heating tubes are at least three in number and are arranged in a ring above the converging part. The inner heating tubes have a vertically extending spiral structure, and the diameter of the tangent circle formed by the innermost points of the at least three inner heating tubes is 2 / 5 to 3 / 5 of the inner diameter of the vessel.

[0011] Preferably, the inner diameter of the spirally coiled inner heating tube is 1 / 4 to 1 / 3 of the inner diameter of the vessel body.

[0012] Preferably, the spiral height of the internal heating tube is 1 / 3 to 2 / 5 of the height of the vessel body.

[0013] Preferably, the number of internal heating tubes is 6.

[0014] Preferably, a support column is provided inside the vessel body, and the internal heating tube is fixed to the support column.

[0015] Preferably, an outer wall heating tube B is also provided on the outside of the vessel body. The outer wall heating tube B is spirally wound on the outer surface of the portion above the constriction of the vessel body and is at the same height as the inner heating tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This solution transforms the traditional method of external heating and central stirring to achieve uniform heating of materials into regional heating centered on each internal heating tube by setting multiple sets of annularly distributed internal heating tubes inside the vessel.

[0018] In this heating method, the high-viscosity material in each heating zone can receive heat radiated from the internal heating tube of that zone. Simultaneously, the edges of the divided zones can benefit from the superposition of heat radiated from adjacent internal heating tubes, ensuring uniform heating. In other words, with this structural design, uniform heating of the high-viscosity material inside the reactor can be achieved without the need for stirring, as is common in traditional reactors.

[0019] Furthermore, it should be noted that in this design, the converging section at the bottom of the reactor serves to facilitate the flow of high-viscosity materials. When the high-viscosity material is heated by the internal heating pipes, its fluidity increases. This more fluid material then enters the converging section below. At this point, external wall heating is applied to the converging section. The reduced viscosity and increased fluidity of the material effectively achieve the required heating uniformity within the converging section. Additionally, the converging section has a gradually decreasing diameter. The heat radiated by the external wall heating pipe A, coiled around the outside of the converging section, is better distributed to the central material as the diameter decreases, ensuring uniform heating during subsequent discharge.

[0020] Furthermore, it should be noted that the inner heating tube has a coiled spiral structure, and the diameter of the tangent circle formed by the innermost point of the inner heating tube is 2 / 5 to 3 / 5 of the inner diameter of the vessel. This structure effectively ensures uniform heating in the area where the inner heating tube is located, while multiple heating tubes can also radiate heat towards the center of the vessel, thus achieving a similar degree of heating between the center of the vessel and the area containing the inner heating tube.

[0021] 2. Controlling the inner diameter of the spiral structure of the inner heating tube to be between 1 / 4 and 1 / 3 of the inner diameter of the vessel body. At this size, the heat radiation area that each inner heating tube can cover will achieve the consistency of overall area heating after being superimposed on each other, thereby better realizing the effective heating of high viscosity materials in the vessel body.

[0022] 3. Under this design, the presence of zoned heating allows materials to be heated quickly and evenly without stirring. Therefore, the height of the internal heating tube only needs to be 1 / 3 to 2 / 5 of the height of the vessel body to maximize the utilization of thermal energy and reduce ineffective heating strokes.

[0023] 4. The purpose of setting up support columns is that although high-viscosity materials achieve a decrease in viscosity and an increase in fluidity due to heating, there is still a significant downward pulling effect on the internal heating tube during its downward flow. In order to maintain the stability of the spiral winding structure of the internal heating tube, setting up support columns and fixing the internal heating tube to the support columns is obviously a very simple and effective method.

[0024] 5. Installing an external heating pipe B on the outside of the vessel body can effectively supplement the heating method of this scheme, so as to make corresponding remedies in some special cases (when the heating by the internal heating pipe and the external wall heating pipe A still cannot achieve the desired effect).

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figures 1-3 The diagram illustrates a large-volume reactor suitable for high-viscosity adhesive materials, comprising a reactor body 1. In this design, the reactor body is a large-volume reactor with a diameter between 2 and 3 meters, providing a continuous supply of raw materials for large-scale adhesive production. In this design, the bottom of the reactor body 1 has a constriction section 11, which is conical in shape and gradually increases in diameter from bottom to top. It is important to note that traditional large-diameter reactors incorporate a stirring mechanism inside the reactor body to ensure uniform heating of the internal materials. However, high-viscosity materials exhibit strong hysteresis during stirring, requiring a particularly high-power stirring mechanism, resulting in a significant energy consumption and substantial cost pressure for enterprises. Furthermore, due to the strong adhesion between high-viscosity materials and the inner wall of the reactor body 1, the outer wall of the reactor body would be subjected to a very large reaction torque if a stirring mechanism is used, easily leading to deformation. This necessitates thickening the reactor wall, further increasing the manufacturing cost. The combination of these two factors results in persistently high costs for existing enterprises when handling high-viscosity materials. Therefore, it is essential to design a reaction vessel capable of addressing these issues.

[0033] This solution proposes the following approach. Specifically, an outer wall heating tube A2 is spirally wound around the outer surface of the converging part 11. Both ends of the outer wall heating tube A2 are connected to a high-temperature steam pipe, providing external heating energy through the high-temperature steam passing through the pipe. Simultaneously, at least three sets of inner heating tubes 3 are arranged inside the vessel body 1, positioned above the converging part 11 and extending spirally upwards. It should be noted that the at least three sets of inner heating tubes are evenly distributed around the vessel body, and the diameter of the circle formed by the innermost points of the at least three sets of inner heating tubes 3 in a tangent configuration is between 2 / 5 and 3 / 5 of the inner diameter of the vessel body 1. Furthermore, in this structure, the heating area inside the vessel body 1 is evenly divided into fan-shaped regions centered on each heating tube by multiple sets of inner heating tubes, thus achieving uniform heating of each region. The central part of the vessel body, farther from the inner heating tubes, can achieve consistent heating through the superposition of heat radiation from multiple inner heating tubes.

[0034] It is important to note that, as a further improvement to the above scheme, the inner diameter of the spiral structure of the inner heating tube 3 is 1 / 4 to 1 / 3 of the inner diameter of the vessel body 1. This ensures that the inner and outer radiation areas of the inner heating tube remain close. That is, the distance between the outward radiation channel of the inner heating tube and the center of the vessel body is close to the distance between the center of the radiation channel itself. Thus, the material at the center of the spiral structure of the inner heating tube achieves equivalent heating to the material near the inner heating tube through its own annular radiation, while the material near the center of the vessel body achieves equivalent heating to the central region through the annular array formed by multiple inner heating tubes.

[0035] It should be noted that, as a further improvement to the above scheme, in order to reduce ineffective heating and thus improve heating efficiency, the spiral height of the inner heating tube in this scheme is between 1 / 3 and 2 / 5 of the height of the vessel body 1.

[0036] It should be noted that, as a further improvement to the above scheme, the number of internal heating tubes 3 is 6, and they are evenly distributed in a ring.

[0037] It should be noted that, as a further improvement to the above solution, in order to ensure that the inner heating tube of the spiral structure will not be pulled and deformed during the falling of high-viscosity materials, that is, to maintain the stability of the spiral structure of the inner heating tube during long-term operation, a support column 4 is also provided in the vessel body 1 of this solution. Each spiral ring of the inner heating tube 3 is fixed to the support column by bolts or pipe clamps.

[0038] It should be noted that, as a further improvement to the above solution, this solution inevitably encounters the problem of insufficient heating capacity during the actual heating process. Therefore, an outer wall heating tube B5 is spirally coiled around the outside of the vessel body 1. Specifically, this outer wall heating tube B is wound around the outer wall of the vessel body above the converging part, and the height of the outer wall heating tube B is the same as the height of the inner heating tube 3.

[0039] Working Principle: After the high-viscosity material enters the vessel through the external pipe, it flows and levels itself within the vessel. Then, this portion of material slowly descends along the bottom discharge path and passes through the radiation zone of the internal heating pipe within the vessel. During this process, the internal heating pipe provides uniform heating to this portion of the material. It's important to note that due to the outer ring partitioning and central overlapping of the internal heating pipes, the degree of heating within the vessel along the section containing the internal heating pipe tends to be uniform, ensuring consistent heating of the material. After being heated by the internal heating pipes, the material enters the lower converging section. At this point, the material's fluidity increases and its viscosity decreases. As the diameter of the converging section narrows, the material converges towards the center, and the diameter gradually decreases. The heat radiated by the outer wall heating pipe A is sufficient to effectively heat the material in the converging section, ensuring temperature consistency between the central and outer areas of the material upon discharge. Furthermore, it should be noted that as the diameter of the converging section decreases, the material on the outside and the material in the center gradually converge and mix. Thus, the inner and outer materials mix and exchange heat in the converging section, thereby further improving the temperature uniformity.

[0040] In summary, the structure of this solution enables uniform heating of high-viscosity materials in a large-volume reactor without the need for a stirrer or thickening of the reactor's outer wall.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
