Description

Technical Field

[0001] This utility model relates to the field of 1-aminoanthraquinone preparation technology, specifically to a high-efficiency temperature-controlled reaction vessel for the preparation of 1-aminoanthraquinone. Background Technology

[0002] The preparation of 1-aminoanthraquinone typically involves an ammoniation reaction of anthraquinone with reagents such as ammonia under specific conditions. The reaction vessel provides a sealed space for this chemical reaction, allowing the reactants to mix thoroughly and react. During the reaction, parameters such as temperature, pressure, reactant concentration, and reaction time must be strictly controlled to ensure the reaction proceeds towards the formation of 1-aminoanthraquinone and to achieve high yield and purity. The preparation of 1-aminoanthraquinone is primarily carried out in a reaction vessel.

[0003] For example, the prior art application number CN202321685180.2 discloses a high-efficiency reactor for the production of 1-aminoanthraquinone, including a reactor body, and a heater is provided on the inner wall of the reactor body. A discharge pipe is connected to the bottom of the reactor body. A heat dissipation cylinder is installed on the outer wall of the reactor body. A heat-conducting circular plate is provided on the inner side of the inner cavity of the heat dissipation cylinder. Multiple sets of heat dissipation copper pipes are connected to the outer wall of the heat-conducting circular plate. Four sets of heat dissipation fans are connected to the outer side of the inner cavity of the heat dissipation cylinder through a bracket. Heat dissipation vents are opened on the outer side of the heat dissipation fans. A drive motor is installed in the middle of the upper surface of the reactor body. A stirring cylinder is connected to the output end of the drive motor. Multiple sets of stirring blades are installed on the outer wall of the stirring cylinder. An arc-shaped scraper is provided on the outer side of the stirring blades.

[0004] The prior art described above, through practical use, mainly relies on heating plates located around the reactor body for heating. However, this heating method is prone to heat dissipation into the heat dissipation copper pipes during the heating process, causing interference between the heat dissipation and heating systems, resulting in low efficiency in both heating and heat dissipation. Therefore, we have improved the prior art based on actual usage. Utility Model Content

Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0006] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-efficiency temperature-controlled reactor for the preparation of 1-aminoanthraquinone includes a reactor body, with a first cylinder and a second cylinder arranged on the outer surface of the reactor body, two feed hoppers arranged at the upper end of the reactor body, a stirring rod rotatably arranged inside the reactor body, and an electromagnetic induction heating coil and a heat insulation component arranged on the outer surface of the reactor body; the heat insulation component includes an aerogel plate and a nano heat insulation coating, the aerogel plate is arranged on the outer surface of the reactor body and a nano heat insulation coating is arranged on one side of the aerogel plate.

[0009] Furthermore, a motor is fixed to the upper end of the reactor body, and a connecting shaft is fixed to the output end of the motor. The lower end of the connecting shaft passes through the reactor body and is fixed to the stirring rod to drive the stirring rod to rotate.

[0010] Furthermore, a temperature controller is provided at the upper end of the reactor body, and at least three fiber optic temperature sensors are arranged in a ring around the inner wall of the reactor body.

[0011] Furthermore, a first cylinder is integrally formed on the outer surface of the reactor body, and a second cylinder is integrally formed on the outer surface of the first cylinder.

[0012] Furthermore, the inner wall of the second cylinder is integrally provided with copper needles, a fan is provided inside the upper end of the second cylinder, and an exhaust hole is provided at the lower end of the second cylinder.

[0013] Furthermore, a discharge pipe is provided at the lower end of the reactor body, and a solenoid valve is installed on the discharge pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Aerogel insulation material is installed inside the No. 1 cylinder. Aerogel has an extremely low thermal conductivity, and its insulation performance is several times that of traditional insulation materials. At the same time, the surface of the aerogel is coated with a nano-insulating coating to further prevent heat loss. This double insulation ensures that heat is concentrated inside the reactor. It can effectively prevent the heat from the electromagnetic induction heating coil from being transferred to the surrounding area and the copper pins used for heat dissipation, ensuring that heat is mainly transferred to the inside of the reactor, avoiding mutual interference between the heat dissipation and heating systems, and improving heating and heat dissipation efficiency. It also avoids the risk of burns to operators.

[0016] 2. The temperature controller increases the fan speed to enhance heat dissipation when the temperature is too high, and increases the power of the electromagnetic induction heating coil when the temperature is too low, based on the preset temperature range, to achieve precise heat dissipation and heating.

[0017] 3. Distributed fiber optic temperature sensors are evenly distributed in a ring at key locations within the reactor body. Based on optical time-domain reflectometry, these sensors can monitor the temperature at different locations in real time with high precision, and are unaffected by electromagnetic interference. They can automatically adjust the power of the electromagnetic induction heating coil according to the temperature controller's preset program and real-time temperature data to achieve precise and efficient temperature control.

[0030] Please see Figures 1 to 4 This utility model provides a technical solution: a high-efficiency temperature-controlled reactor for the preparation of 1-aminoanthraquinone, including a reactor body 1, a first cylinder 2 and a second cylinder 6 arranged on the outer surface of the reactor body 1, a cover plate 3 arranged at the upper end of the reactor body 1, two feed hoppers 4 arranged at the upper end of the cover plate 3, a stirring rod 5 rotatably arranged inside the reactor body 1, an electromagnetic induction heating coil 7 and a heat insulation component 8 arranged on the outer surface of the reactor body 1; the heat insulation component 8 includes an aerogel plate 81 and a nano heat insulation coating 82, the aerogel plate 81 is arranged on the outer surface of the reactor body 1 and the nano heat insulation coating 82 is arranged on one side of the aerogel plate 81.

[0032] refer to Figure 2 A temperature controller 13 is installed at the upper end of the reactor body 1. At least three fiber optic temperature sensors 12 are arranged in a ring around the inner wall of the reactor body 1 for detecting temperature. A discharge pipe is installed at the lower end of the reactor body 1, and a solenoid valve is installed on the discharge pipe for discharging material.

[0033] refer to Figure 2 and Figure 3The outer surface of the reactor body 1 is integrally provided with a first cylinder 2, and the outer surface of the first cylinder 2 is integrally provided with a second cylinder 6. The inner wall of the first cylinder 2 is fixed with an aerogel plate 81 by rivets. The inner side of the aerogel plate 81 is coated with a nano heat insulation coating 82, which is a nano metal oxide, such as titanium dioxide (TiO2) or zinc oxide (ZnO).

[0034] refer to Figure 2 The inner wall of the second cylinder 6 is integrally provided with copper needles 9 to increase the heat dissipation speed. A fan 10 is provided in the upper end of the second cylinder 6, and an exhaust hole 11 is provided in the lower end of the second cylinder 6. When the fan 10 is started, it will take away the heat around the copper needles 9 and discharge it through the exhaust hole 11, thereby increasing the heat dissipation speed.

[0035] Working principle: During operation, the material is fed into the reactor body 1 through the feed hopper 4. Then, the electromagnetic induction heating coil 7 is activated by the temperature controller 13 to heat the reactor body 1. Distributed fiber optic temperature sensors 12 are evenly distributed in a ring at key locations within the reactor body 1. Based on optical time-domain reflectometry, the fiber optic temperature sensors 12 can monitor the temperature at different locations in real time with high precision and are unaffected by electromagnetic interference.

[0036] Aerogel plate 81, a heat insulation material, is installed inside cylinder 2. Aerogel plate 81 has an extremely low thermal conductivity, and its heat insulation performance is several times that of traditional heat insulation materials. Simultaneously, a nano-heat insulation coating 82 is applied to the surface of aerogel plate 81 to further prevent heat loss. This double insulation ensures that heat is concentrated within the reactor body 1. It effectively prevents heat from the electromagnetic induction heating coil 7 from being transferred to the surrounding area and to the copper pins 9 used for heat dissipation, ensuring that heat is mainly transferred to the interior of the reactor body 1. This avoids interference between the heat dissipation and heating systems, improving both heating and heat dissipation efficiency. It also reduces the risk of burns to operators.

[0037] According to the preset temperature range, the temperature controller 13 increases the speed of the fan 10 to enhance heat dissipation when the temperature is too high, and increases the power of the electromagnetic induction heating coil 7 when the temperature is too low, so as to achieve precise heat dissipation and heating.
