Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature-controlled reactor technology, and in particular to a uniform temperature-controlled reaction device with a loading and unloading port. Background Technology
[0002] Uniform temperature-controlled reactors, also known as high-efficiency temperature-controlled reactors, are widely used in chemical, pharmaceutical, biotechnology, and materials science fields to promote and control chemical reaction processes, ensuring that reactants react under suitable temperature and pressure conditions to obtain the desired product. By providing precise temperature control, uniform temperature-controlled reactors help improve reaction efficiency, product quality, and process safety.
[0003] Traditional reactors typically lack dedicated loading and unloading ports. This leads to a series of inconveniences and inefficiencies in practical use. For example, when reactant replacement or reactor cleaning is required, operators must fully open the reactor, which is not only time-consuming and labor-intensive but also introduces contamination risks. Furthermore, the lack of dedicated loading and unloading ports limits the reactor's continuous operation capability, as frequent opening and closing can affect process stability and efficiency.
[0004] Traditional reaction apparatuses typically only have heating or cooling devices on the outside of the chamber. External heating or cooling leads to uneven temperature distribution because heat or cold must be conducted through the reactor walls to the interior, causing localized overheating or undercooling of the reactants. Secondly, external temperature control systems have slow response times, making it difficult to quickly adjust and maintain the precise temperature conditions required for the reaction. Furthermore, external temperature control increases energy consumption because heat or cold is lost during the transfer process.
[0005] In summary, traditional reaction equipment has significant shortcomings in loading and unloading and temperature control, which limits its application in efficient, precise and continuous production processes. Utility Model Content
[0006] The purpose of this invention is to provide a uniform temperature control reaction device with a loading and unloading port to solve the problem that existing reaction devices cannot achieve uniform temperature control.
[0007] This utility model is achieved through the following technical solution:
[0008] A uniform temperature-controlled reaction device with a loading and unloading port includes a cavity filled with a reactant. An inlet pipe and an outlet pipe are provided above the cavity and are connected to each other and extend into the cavity. Along the direction of gravity of the gas, the end of the outlet pipe extending into the cavity is lower than the end of the inlet pipe extending into the cavity. A number of heat-conducting rods are provided in the cavity, and the end of each heat-conducting rod is connected to the inner wall of the cavity. The heat-conducting rods arranged along the horizontal plane and the heat-conducting rods perpendicular to the horizontal plane intersect to form a "well" shaped structure.
[0009] Gas enters the chamber through the inlet pipe and is evenly distributed onto the reactant surface from above. Because the outlet pipe is positioned lower than the inlet pipe, the gas has more time to react with the reactant before leaving the reactor, thus increasing the conversion rate of the reactants and the purity of the products. The "well"-shaped structure of the heat-conducting rod is designed to achieve a uniform temperature distribution. The heat-conducting rod is connected to the inner wall of the chamber and distributes heat evenly to the reactant through thermal conduction, ensuring that the reaction proceeds under constant temperature conditions.
[0010] As a preferred technical solution of this utility model, a loading pipe is provided above the cavity and a unloading pipe is provided below the cavity; both the loading pipe and the unloading pipe are connected to the inside of the cavity.
[0011] In a preferred embodiment of this invention, multiple heat-conducting rods forming a "well" shape together constitute a heat-conducting assembly. Multiple heat-conducting assemblies are installed within the cavity at different heights, with each assembly evenly spaced apart. By setting multiple heat-conducting assemblies at different heights, the temperature requirements of different areas within the reactor can be precisely adjusted.
[0012] In a preferred embodiment of this invention, the heat-conducting rod has a circular cross-sectional shape. A circular cross-section heat-conducting rod can provide uniform heat conduction.
[0013] In a preferred embodiment of this invention, in each heat-conducting component, the heat-conducting rods arranged along the horizontal plane form an acute angle with the horizontal plane; the heat-conducting rods perpendicular to the horizontal plane are at the same height. This increases the contact area between the heat-conducting rods and the reactant, thereby improving heat transfer efficiency.
[0014] In a preferred embodiment of this invention, the loading pipe and unloading pipe are arranged coaxially in the vertical direction. This ensures that the flow path of the material during addition and removal is straight, reducing the residence time of the material inside the reactor.
[0015] In a preferred embodiment of this invention, the end of the inlet pipe extending into the cavity is connected to an inlet anti-blocking head, and the end of the outlet pipe extending into the cavity is connected to an outlet anti-blocking head. This prevents solid particles or other substances generated during the reaction process from blocking the gas flow path.
[0016] As a preferred technical solution of this utility model, an upper hemispherical end cap is connected above the cavity, and a lower hemispherical end cap is connected below the cavity.
[0017] In a preferred embodiment of this invention, both the intake pipe and the outlet pipe are composed of different connecting sections, which are connected by a VCR connector. Using a VCR connector ensures high airtightness between the intake and outlet pipes, reducing the risk of leakage.
[0018] As a preferred technical solution of this utility model, the cavity is cylindrical, and the air inlet pipe and the air outlet pipe are arranged along the diameter of the circular cross-section of the cavity.
[0019] Compared with existing technologies, this invention has the following advantages and beneficial effects: By setting heat-conducting rods in a cross-shaped pattern inside the reactor and adopting an inclined design, this invention increases the contact area with the reactants, promotes uniform heat distribution, and enhances the mixing effect of the reactants. This helps maintain temperature uniformity during the reaction process, avoids local overheating or undercooling, thereby improving the efficiency of the chemical reaction and the quality of the products.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit it. It should be noted that this utility model is already in the actual research and development stage.

The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.
[0034] Traditional reactor designs often neglect dedicated loading and unloading pipelines, leading to a series of inconveniences and efficiency problems in actual operation. For example, changing reactants or cleaning the reactor requires fully opening the reactor, increasing operating time and labor intensity, and introducing contamination. Simultaneously, the lack of dedicated loading and unloading ports restricts the reactor's continuous operation capability, as frequent opening and closing disrupts process stability and efficiency. Furthermore, traditional devices typically only have heating or cooling systems external to the reactor cavity. This external temperature control method easily leads to uneven temperature distribution because heat or cold must be conducted through the reactor walls to the interior, causing localized overheating or undercooling of the reactants. External temperature control systems generally have slow response times, making it difficult to quickly adjust and maintain precise reaction temperature conditions. Moreover, this method increases energy consumption due to losses during heat or cold transfer.
[0035] Example 1:
[0036] like Figures 1-2 As shown, a uniform temperature-controlled reaction device with a loading and unloading port includes a cavity 1 filled with reactant 8. An inlet pipe 4 and an outlet pipe 5 are provided above the cavity 1, which are connected to and extend into the cavity 1. Along the direction of gravity of the gas, the end of the outlet pipe 5 extending into the cavity 1 is lower than the end of the inlet pipe 4 extending into the cavity 1. A number of heat-conducting rods 3 are provided inside the cavity 1. The end of each heat-conducting rod 3 is connected to the inner wall of the cavity 1. The heat-conducting rods 3 arranged along the horizontal plane and the heat-conducting rods 3 perpendicular to the horizontal plane intersect to form a "well" shaped structure.
[0037] The working principle of this reaction apparatus is based on the chemical reaction of reactant 8 within chamber 1, with reaction conditions optimized through precise temperature control. The arrangement of the inlet pipe 4 and outlet pipe 5 is designed to optimize the contact between the gas and the reactant 8. The gas enters chamber 1 through inlet pipe 4 and is evenly distributed from above onto the surface of the reactant 8. Because the outlet pipe 5 is positioned lower than inlet pipe 4, the gas has more time to react with the reactant 8 before leaving the reactor, thereby increasing the conversion rate of the reactants and the purity of the products.
[0038] The "well"-shaped structure of the heat-conducting rod 3 is designed to achieve a uniform temperature distribution. The heat-conducting rod 3 is connected to the inner wall of the cavity 1, and distributes heat evenly to the reactant 8 through heat conduction, ensuring that the reaction proceeds under constant temperature conditions, effectively preventing local overheating or overcooling, and improving the selectivity of the reaction and the purity of the product.
[0039] In actual production and manufacturing, forced convection can be used to promote gas flow through fans or other mechanical devices, rather than simply relying on the natural path of gas flow; in addition to the heat-conducting rod 3, electric heaters or cooling coils can also be used to achieve temperature control, which can provide faster response speeds in some cases; the "well" shaped structure of the heat-conducting rod 3 can be replaced with other shapes of heat-conducting structures, such as spiral or mesh structures, to adapt to different reaction requirements and space constraints.
[0040] As a further implementation of this embodiment, a loading pipe 6 is provided above the cavity 1, and a unloading pipe 7 is provided below the cavity 1; both the loading pipe 6 and the unloading pipe 7 are connected to the interior of the cavity 1.
[0041] By installing the loading pipe 6 above the chamber 1, new reactants or catalysts can be added to the reactor without interfering with the reaction process. Similarly, the unloading pipe 7 is located below the chamber 1, facilitating the removal of products or unreacted reactants after the reaction is complete. This improves operational convenience and efficiency, reduces the number of times the reactor is opened and closed, thereby lowering the risk of contamination and operating costs.
[0042] like Figure 2 As shown, in a further implementation of this embodiment, multiple heat-conducting rods 3 forming a "well"-shaped structure together constitute a heat-conducting component; at different height positions of the cavity 1, multiple heat-conducting components are provided inside the cavity 1, with each heat-conducting component evenly spaced apart. This means that the heat conduction structure inside the reactor is modular and can be adjusted and optimized as needed.
[0043] The design of the heat-conducting components allows for more flexible control of the temperature distribution inside the reactor. By placing multiple heat-conducting components at different heights, precise temperature adjustments can be made for different areas within the reactor to meet their specific needs. For example, more heat-conducting components can be placed in areas of high reactivity to enhance heat transfer, while fewer components can be used in areas with less temperature variation, improving the accuracy of temperature control and reaction efficiency. Other options can also be considered: dividing the reactor interior into multiple independent temperature-controlled zones, each with its own independently adjustable temperature; or using a sensor and feedback control system to dynamically adjust the output of heating or cooling elements based on real-time temperature data.
[0044] As a further implementation of this embodiment, the heat-conducting rod 3 has a circular cross-sectional shape. A circular cross-section heat-conducting rod 3 can provide uniform heat conduction because the thermal conductivity of a circle is consistent in all directions, which helps to achieve a uniform temperature distribution inside the reactant 8 and avoids uneven reaction caused by temperature gradients. Furthermore, a circular heat-conducting rod 3 is relatively simple to manufacture and can be easily produced through standard machining processes, helping to control costs and improve production efficiency. Square or rectangular cross-sections offer better structural stability or thermal conductivity in certain applications; an elliptical shape can provide a larger contact area while maintaining good thermal conductivity.
[0045] As a further implementation of this embodiment, in each heat-conducting component, the heat-conducting rod 3 arranged along the horizontal plane forms an acute angle with the horizontal plane; the heat-conducting rod 3 perpendicular to the horizontal plane is at the same height.
[0046] By arranging the horizontally arranged heat-conducting rods 3 at an acute angle to the horizontal plane, the contact area between the heat-conducting rods 3 and the reactant 8 can be increased, thereby improving heat transfer efficiency. Simultaneously, ensuring that the vertically arranged heat-conducting rods 3 are at the same height helps maintain temperature uniformity within the reactor. This design contributes to a more uniform temperature distribution, improving reaction efficiency and product consistency. The particle size and shape of the reactant 8 have a significant impact on the reaction process; smaller particle sizes typically provide a larger surface area, which is beneficial for increasing the reaction rate.
[0047] like Figure 1 As shown, in a further implementation of this embodiment, the loading pipe 6 and the unloading pipe 7 are arranged coaxially in the vertical direction. By arranging the loading pipe 6 and the unloading pipe 7 coaxially, the flow path of the material during addition and removal can be ensured to be straight, reducing the residence time of the material inside the reactor. This design helps to improve the ease of operation and reduce contamination or uneven reaction problems caused by material retention. In some applications, a multi-channel system can be used to process multiple materials simultaneously, improving processing efficiency.
[0048] As a further implementation of this embodiment, an intake anti-blocking head 41 is connected to the end of the intake pipe 4 that extends into the cavity 1, and an outlet anti-blocking head 51 is connected to the end of the outlet pipe 5 that extends into the cavity 1. The anti-blocking heads are to prevent solid particles or other substances generated during the reaction from blocking the gas flow path. Integrating filters into the intake pipe 4 and outlet pipe 5 can more effectively capture solid particles; integrating automatic cleaning mechanisms, such as reverse airflow cleaning or mechanical brushing, can reduce maintenance requirements.
[0049] As a further implementation of this embodiment, an upper hemispherical head 21 is connected above the cavity 1, and a lower hemispherical head 22 is connected below the cavity 1. To enhance the structural strength and pressure resistance of the reactor, this shape provides a uniform stress distribution within the pressure vessel, reduces stress concentration points, and improves the overall safety and durability of the reactor. Other head shapes can also be considered: elliptical heads, which provide similar stress distribution characteristics and are more suitable for certain space constraints; and dished heads, which combine flat areas and curved edges, suitable for applications requiring flat surfaces.
[0050] Example 2:
[0051] like Figure 1 As shown, in a further implementation of the above embodiment, both the intake pipe 4 and the exhaust pipe 5 are composed of different connecting sections, which are connected by a VCR connector. The VCR connector is a high-precision sealing connection method, commonly used in applications requiring high airtightness. Using a VCR connector ensures high airtightness in the connection between the intake pipe 4 and the exhaust pipe 5, reducing the risk of leakage. This connection method also facilitates disassembly and reassembly, which is beneficial for maintenance and component replacement.
[0052] As a further implementation of this embodiment, the cavity 1 is cylindrical, with the inlet pipe 4 and outlet pipe 5 arranged along the diameter of the circular cross-section of the cavity 1. The cylindrical cavity 1 is easy to manufacture and process, while providing a larger internal space, which is beneficial for the thorough mixing and reaction of reactants. The arrangement of the inlet pipe 4 and outlet pipe 5 along the diameter ensures uniform gas distribution inside the reactor, improving reaction efficiency. Although the cylindrical design is very effective in many applications, other shapes of the cavity 1 can also be considered; square or rectangular cavities 1 are more suitable for certain space-constrained applications; spherical cavities 1 provide the largest internal volume to surface area ratio, suitable for applications requiring maximum reaction space.
