Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, and in particular to a formaldehyde-free adhesive reaction vessel with rapid temperature control. Background Technology

[0002] Reactors are core equipment used in industries such as chemical, pharmaceutical, food, and new materials to realize chemical reactions. They are usually made of corrosion-resistant materials such as stainless steel and titanium alloys, and have the characteristics of being sealed and pressure-resistant, and having controllable temperature / pressure. They can be equipped with stirring devices, heat exchange jackets or coils inside, and external auxiliary systems such as temperature control, pressure monitoring, and feeding / discharging are provided.

[0003] Reactors provide stable process conditions such as temperature, pressure, and stirring rate for chemical reactions, and are suitable for various reaction scenarios such as homogeneous and heterogeneous oxidation, reduction, polymerization, and synthesis. They support small-batch research and development in laboratories and can also meet the needs of large-scale industrial production. By precisely controlling reaction parameters, they ensure product purity and yield, and are a key core device in chemical production processes to realize the transformation of raw materials into target products.

[0004] Reactors are generally equipped with an outer jacket. By introducing high-temperature steam or other media into the jacket, the internal temperature can be affected, thereby enabling the internal temperature of the reactor to reach the optimal reaction temperature. However, the current method of temperature control by relying solely on the jacket is relatively slow and cannot quickly bring the internal temperature of the reactor to the required level.

[0005] Therefore, it is necessary to provide a formaldehyde-free adhesive reaction vessel with rapid temperature control to solve the above-mentioned technical problems. Utility Model Content

Multiple annular temperature-conducting plates are fixedly connected to the inner surface of the reaction vessel body, evenly spaced along its height.

Heat exchange vertical pipes are vertically fixedly connected inside the aligned connecting holes. The top or bottom ends of some adjacent heat exchange vertical pipes are connected by bent pipes, which are spaced apart from each other between the top and bottom ends of the heat exchange vertical pipes. The top ends of two heat exchange vertical pipes are connected to inlet / outlet pipes that extend outwards through the side wall of the reaction vessel body.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1-3 The rapid temperature-controlled formaldehyde-free adhesive reactor includes a reactor body 1 with an open top. Multiple annular temperature-conducting plates 2 are fixedly connected to the inner surface of the reactor body 1 and are evenly spaced along its height. Multiple connecting holes 3 are vertically opened on the upper surface of the multiple temperature-conducting plates 2. The multiple connecting holes 3 on the multiple temperature-conducting plates 2 are evenly spaced along the circumference of the reactor body 1 and are aligned in the height direction. Heat exchange vertical pipes 4 are vertically fixedly connected inside the multiple connecting holes 3 aligned in the height direction. The top or bottom of some adjacent heat exchange vertical pipes 4 are connected by a bend 5. Multiple bends 5 are spaced apart between the top and bottom of the multiple heat exchange vertical pipes 4. The top of the two heat exchange vertical pipes 4 are connected to inlet and outlet pipes 6 that penetrate the side wall of the reactor body 1 and extend outward.

[0021] The device has multiple annular heat-conducting fins 2 evenly spaced along the height of the inner wall surface of the reactor, and vertical heat exchange risers 4 are set in the multiple heat-conducting fins 2. The multiple heat exchange risers 4 are interconnected by bends 5 to form a serpentine structure. When the reactor is in actual operation, the heat exchange medium is sent into the serpentine heat exchange pipeline through an inlet / outlet pipe 6 to exchange heat with the multiple heat-conducting fins 2. The multiple heat-conducting fins 2 also increase the contact area between the inner wall surface of the reactor and the material, which can more quickly regulate the temperature of the material and thus quickly reach the optimal reaction temperature.

[0022] The reactor body 1 is also equipped with parameter devices such as thermometers to monitor the temperature and other values ​​inside the reactor in real time.

[0023] The bottom of the reactor body 1 is recessed to form a funnel shape, and the bottom of the reactor body 1 is vertically connected to a drain pipe 7.

[0024] The bottom end of the drain pipe 7 is equipped with a valve structure. After the reaction is completed, the valve structure can be opened to discharge the material inside the reactor. The funnel-shaped bottom structure can prevent material from remaining inside the reactor.

[0025] The top of the reactor body 1 is detachably fitted with an equipment cover 9. The top of the equipment cover 9 is provided with a drive structure 11. The output shaft of the drive structure 11 rotatably passes through the equipment cover 9 and extends to its bottom end. The bottom end of the output shaft of the drive structure 11 is vertically fixedly connected to a stirring shaft extending into the interior of the reactor body 1. Multiple stirring blades are fixedly connected to the outer surface of the stirring shaft.

[0026] The drive structure 11 includes a motor, shaft seal, and other structures, which are mature existing technologies. The specific effects will not be elaborated here. The drive structure 11 drives the stirring shaft to rotate, thereby driving the stirring blades to rotate and stirring the materials inside the reactor, thereby accelerating the reaction of the materials and improving production efficiency.

[0027] A first flange 8 is fixedly connected to the outer edge of the top of the reactor body 1, and a second flange 10 is fixedly connected to the outer edge of the bottom of the equipment cover 9. The equipment cover 9 is detachably installed on the top of the reactor body 1 through the second flange 10.

[0028] Flange structures offer good sealing and are easy to install and disassemble, making them suitable for use in reactors.

[0029] The inner edges of multiple temperature-conducting plates 2 are all inclined downwards.

[0030] The inner edges of the multiple temperature-conducting plates 2 are tilted downwards so that material will not remain between two adjacent temperature-conducting plates 2.

[0031] Multiple support legs 12 are vertically fixedly connected to the outer surface of the reactor body 1, and a reinforcing frame 13 is horizontally fixedly connected between every two adjacent support legs 12.

[0032] The support leg 12 provides support, and multiple reinforcement frames 13 can improve the support stability of the support leg 12.

[0033] Multiple heat exchange vertical pipes 4 and multiple bends 5 have multiple grooves 14 evenly spaced along their circumferential cross-section on their inner surfaces.

[0034] Multiple grooves 14 can increase the contact area between the inner surface of the heat exchange vertical tube 4 and the bend 5 and the heat exchange medium, thereby further improving the heat exchange and temperature regulation effect of the device.

[0035] The working principle of the formaldehyde-free adhesive reaction vessel with rapid temperature control provided by this utility model is as follows: When using the device, the material is first sent into the interior of the reaction vessel body 1, then the equipment cover 9 is installed on the reaction vessel body 1, then the drive structure 11 is started and a heat exchange medium is sent into an inlet / outlet pipe 6. The heat exchange medium flows through the serpentine heat exchange vertical pipe 4 and the bend pipe 5 to exchange heat with the temperature conducting plates 2. The multiple temperature conducting plates 2 increase the contact area between the inner wall surface of the reaction vessel and the material, which can more quickly regulate the temperature of the material and thus quickly reach the optimal reaction temperature. The drive structure 11 can drive the stirring shaft to rotate continuously, and the stirring blades at its bottom stir the material so that the material reacts rapidly at the reaction temperature.

[0036] Compared with related technologies, the formaldehyde-free adhesive reaction vessel with rapid temperature control provided by this utility model has the following beneficial effects: The device is equipped with temperature-conducting plates 2 and multiple heat exchange vertical pipes 4. Multiple annular temperature-conducting plates 2 are evenly spaced along the height direction on the inner wall surface of the reaction vessel, and vertical heat exchange vertical pipes 4 are set in the multiple temperature-conducting plates 2. The multiple heat exchange vertical pipes 4 are interconnected by bends 5 to form a serpentine structure. When the reaction vessel is actually working, the heat exchange medium is sent into the serpentine heat exchange pipeline through an inlet / outlet pipe 6 to exchange heat with the multiple temperature-conducting plates 2. The multiple temperature-conducting plates 2 also increase the contact area between the inner wall surface of the reaction vessel and the material, which can more quickly regulate the temperature of the material and thus quickly reach the optimal reaction temperature.
