[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0030] Please refer to Figures 1-5 , in the embodiment of the present utility model, a high-efficiency stainless steel reaction kettle includes
[0031] a reaction kettle 4 embedded on the frame body 1, and the reaction kettle 4 is fixedly connected to the frame body 1 through corner seats around it; the reaction kettle 4 includes a kettle body 41, and the kettle body 41 has an interlayer 42;
[0032] It also includes a steam inlet pipe 10, a brine inlet pipe 5, a circulating water inlet pipe 6, a brine discharge pipe 7, a circulating water discharge pipe 8, and a compressed air inlet pipe 9; among them, the steam inlet pipe 10, the brine inlet pipe 5, the circulating water inlet pipe 6, the brine discharge pipe 7, and the circulating water discharge pipe 8 are all connected to the interlayer 42 inside the kettle body 41.
[0033] In this embodiment, the steam inlet pipe 10 is located on one side of the reaction kettle 4 and is connected to the inner interlayer 42; and a pressure relief valve is threadedly connected to the outside of the interlayer 42.
[0034] By adopting the above technical solution, steam enters the interlayer 42 through the steam inlet pipe 10; the steam can provide heat energy to heat the materials in the reaction kettle 4 to the required reaction temperature; this is crucial for many chemical reactions that need to be carried out at a certain temperature. For example, in some organic synthesis reactions, the reactants need to be heated to a specific temperature to make the reaction proceed smoothly;
[0035] By adjusting the flow rate and pressure of the steam, the temperature in the reaction kettle can be precisely controlled to keep it within a stable range, thereby ensuring the selectivity and yield of the reaction.
[0036] In this embodiment, the compressed air inlet pipe 9 penetrates from the reaction kettle 4 to the inside of the reaction kettle 4.
[0037] By adopting the above technical solution, the compressed air inlet pipe 9 penetrates to the inside of the reaction kettle 4, and when in use, compressed air can be transported into the reaction kettle 4 so that the compressed air is transported into the liquid medicine;
[0038] When the reactants need to be evenly distributed to ensure the smooth progress of the reaction, the compressed air can enter the reaction kettle by means of bubbling or spraying, promoting the stirring and mixing of the materials in the kettle, enabling the reactants to come into contact more fully, thereby improving the reaction efficiency and uniformity.
[0039] In this embodiment, there are two circulating water inlet pipes 6, both of which are arranged at the upper end of the kettle body 41; the circulating water discharge pipe 8 is connected to the lower end of the kettle body 41.
[0040] In the pharmaceutical industry, when producing certain drug intermediates, the circulating water cooling system can precisely control the temperature of the reaction kettle, ensuring the accuracy and consistency of drug synthesis.
[0041] In many chemical reactions, a large amount of heat is released. If it is not removed in time, it may lead to out-of-control reactions, an increase in side reactions, or a decrease in product quality.
[0042] By adopting the above technical solution, the circulating water inlet pipe 6 can transport water into the interlayer 42; the circulating water can effectively absorb this heat and reduce the temperature inside the reaction kettle to an appropriate range. For example, in some polymerization reactions with intense exotherm, the circulating water cooling can ensure the smooth progress of the reaction and prevent the polymer from deteriorating due to high temperature.
[0043] In this embodiment, there are two ice brine inlet pipes 5, both of which are arranged at the upper end of the kettle body 41; the ice brine discharge pipe 7 is connected to the lower end of the kettle body 41.
[0044] By adopting the above technical solution, the ice brine can enter the interlayer 42 through the ice brine inlet pipe 5; the ice brine has a low temperature and can effectively absorb the heat generated in the reaction kettle, thereby reducing the temperature of the reaction system. This is crucial for those reactions with intense exotherm and can prevent situations such as increased side reactions, product decomposition, or reaction runaway caused by excessive temperature. For example, in some polymerization reactions, it is necessary to strictly control the temperature to ensure the molecular weight and performance of the polymer, and the ice brine can play a good cooling role.
[0045] By adjusting the flow rate and temperature of the ice brine, the temperature inside the reaction kettle can be precisely controlled, thereby regulating the reaction rate. In some reactions with specific requirements for the reaction rate, this helps to obtain ideal reaction products and yields.
[0046] In this embodiment, the ice brine inlet pipe 5, the circulating water inlet pipe 6, the ice brine discharge pipe 7, the circulating water discharge pipe 8, the compressed air inlet pipe 9, and the steam inlet pipe 10 all penetrate to the lower part of the frame body 1 and are fixedly connected to the frame body 1, and solenoid valves 11 are respectively installed at the upper ends of the ice brine inlet pipe 5, the circulating water inlet pipe 6, the ice brine discharge pipe 7, the circulating water discharge pipe 8, the compressed air inlet pipe 9, and the steam inlet pipe 10.
[0047] The solenoid valve 11 is used to control the opening and closing of the above-mentioned multiple pipes and is controlled according to different production processes. Using the solenoid valve 11 to control the on-off of the pipeline belongs to the prior art and will not be elaborated here.
[0048] In this embodiment, a stirring paddle 43 is provided inside the kettle body 41; the stirring paddle 43 is in transmission connection with the driving assembly 44; the driving assembly 44 is fixed on the top of the kettle body 41.
[0049] In this embodiment, a safety valve 45 is provided at the top of the reaction kettle 4; when compressed air enters the kettle body 41, the internal pressure is bound to increase, and the safety valve 45 can ensure the stability of the pressure and avoid the situation of excessive pressure.
[0050] In this embodiment, a discharge valve 46 is further provided at the bottom of the reactor 4; after the reaction is completed, the materials can be directly discharged.
[0051] In this embodiment, two brackets 2 are further fixed to the upper end of the frame body 1, a top cover 3 is fixed to the upper end of the bracket 2, and markings of each pipe are provided on the outer side of the top cover 3.
[0052] The working principle of the present utility model is as follows: when in use, first, the raw materials to be reacted are added into the inner part of the kettle body 41 through the manhole at the top of the reactor 4, and then the driving assembly 44 is started to drive the stirring paddle 43 to rotate, so as to mix and stir the raw materials; the compressed air inlet pipe 9 penetrates into the inside of the reactor 4, and compressed air can be conveyed into the reactor 4 during use, so that the compressed air is conveyed into the liquid medicine;
[0053] When the reactants need to be evenly distributed to ensure the smooth progress of the reaction, the compressed air enters the reactor in the form of bubbling or spraying, promoting the stirring and mixing of the materials in the kettle, enabling the reactants to contact more fully, thereby improving the reaction efficiency and uniformity;
[0054] In the pharmaceutical industry, when producing certain pharmaceutical intermediates, after heating, it is necessary to carry out a cooling treatment; the circulating water inlet pipe 6 conveys water into the jacket 42 and discharges it through the circulating water discharge pipe 8, thereby realizing the circulation of water; the circulating water cooling system can accurately control the temperature of the reactor, ensuring the accuracy and consistency of drug synthesis;
[0055] In some reactions that require crystallization, ice brine can create suitable low-temperature conditions, promoting the formation and growth of crystals, which is beneficial to the separation and purification of products; the ice brine can enter the jacket 42 through the ice brine inlet pipe 5; the ice brine has a relatively low temperature and can effectively absorb the heat generated in the reactor, thereby reducing the temperature of the reaction system. This is crucial for those reactions with intense heat release, which can prevent situations such as an increase in side reactions, decomposition of products, or reaction runaway caused by too high a temperature. For example, in some polymerization reactions, it is necessary to strictly control the temperature to ensure the molecular weight and performance of the polymer, and the ice brine can play a very good cooling role.
