Description

Technical Field

[0001] This utility model relates to the field of chemical reaction vessel technology, and more specifically, to a reaction vessel for chemical raw materials. Background Technology

[0002] In existing chemical production, the reactor, as a core piece of equipment, is typically composed of a sealed vessel combined with structures for feeding, gas inlet, and stirring. Existing reactors usually require connecting a distillation column and condenser to the reactor via external piping, forming an independent and relatively complex reflux and recovery loop. This lengthy piping layout not only occupies space but also increases maintenance difficulty and the risk of leaks.

[0003] In addition, most inerting protection methods rely on directly introducing nitrogen gas at the inlet of the vessel body, which then flows directly into the vessel after being diverted through pipelines. However, since it is not integrated with the built-in structure, the nitrogen gas is unlikely to form a channel effect in the vessel, making it difficult to achieve uniform replacement and thus failing to ensure a continuous inert environment in the entire vessel cavity.

[0004] In particular, the common threaded or clamp connection method at the bottom outlet, although it can provide a certain degree of sealing, is cumbersome to disassemble and assemble in high-viscosity systems or when frequent process switching is required. It is also difficult to clean thoroughly and material can easily remain in dead corners, increasing the risk of cross-contamination and production downtime. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a reaction vessel for chemical raw materials to solve the above problems.

[0006] The present invention adopts the following solution:

[0007] This application provides a reaction vessel for chemical raw materials, including a tank body with an inner cylinder, a rotary motor mounted on the tank body, and a stirrer connected to the rotary motor and placed inside the tank body; the tank body has a distillation column and a feed inlet at the top, and a nitrogen inlet on the side, the distillation column being connected to the inner cylinder, and the nitrogen inlet being connected to the inner cylinder; the tank body has a mounting hole in the middle, the rotary motor being mounted on the mounting hole and linearly connected to the stirrer through a reducer; the tank body has a ball valve discharge port at the bottom.

[0008] As a further improvement, the distillation column is connected to the inlet side of an external condenser, and the outlet side of the condenser is connected to a receiving tank for waste gas storage.

[0009] As a further improvement, the volume of the receiving tank is smaller than that of the tank body, and the condenser is inclined downwards from the tank body to the receiving tank.

[0010] As a further improvement, the distillation column is positioned vertically below the condenser, and the receiving tank extends vertically below the condenser.

[0011] As a further improvement, the feed inlet is positioned opposite the distillation column on different sides of the mounting hole, and the feed inlet is equipped with a manhole device to facilitate inspection and maintenance.

[0012] As a further improvement, the nitrogen inlet extends horizontally outward on one side of the tank, and the tank is also provided with a wall-mounted channel connecting the inner cylinder and the nitrogen inlet.

[0013] As a further improvement, a temperature measuring port for monitoring the nitrogen temperature is also provided between the wall-mounted channel and the tank body.

[0014] As a further improvement, the lower half of the tank is provided with an outer sleeve that can cover the inner cylinder, and the outer sleeve is made of heat-insulating material.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] 1. The reaction vessel for chemical raw materials of this application has a top distillation column that is directly connected to the inner cylinder, so that light components can be distilled and recovered simultaneously during the reaction process, avoiding the complex layout of external pipelines. The side nitrogen inlet is also directly connected to the inner cylinder, realizing uniform nitrogen replacement in the cylinder area, enhancing the inert protection effect, and reducing the risk of oxidation and side reactions.

[0017] 2. The rotating motor is directly installed in the tank through the central mounting hole and is coaxially connected to the agitator through the reducer. It has high transmission efficiency and a compact structure, eliminating the energy loss and multiple seals of traditional eccentric or bent shaft transmission, reducing the risk of leakage, and improving the uniformity of mixing and the reliability of the system.

[0018] 3. In particular, the bottom ball valve outlet configuration enables one-click quick discharge, avoiding the tedious disassembly and assembly of threads or clamps, and allowing for more thorough cleaning. The machine has a high degree of integration, a small footprint, and simple piping, which facilitates rapid process switching and automated control, further improving production efficiency. Moreover, the reaction, distillation, inerting, stirring, and unloading functions are completed in the same reactor, significantly reducing equipment investment and maintenance costs, which meets the needs of modern chemical continuous and integrated production.

[0023] 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 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. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. Example

[0024] Combination Figures 1 to 2 This embodiment provides a reaction vessel for chemical raw materials, including a tank body 1 with an inner cylinder, a rotary motor 2 mounted on the tank body 1, and a stirrer 3 connected to the rotary motor 2 and placed inside the tank body 1. The tank body 1 has a distillation column 4 and a feed inlet 5 at the top, and a nitrogen inlet 6 on the side. The distillation column 4 and the nitrogen inlet 6 are connected to the inner cylinder. The tank body 1 has a mounting hole in the middle, and the rotary motor 2 is mounted on the mounting hole and linearly connected to the stirrer 3 via a reducer 7. The tank body 1 has a ball valve outlet 8 at the bottom.

[0025] The reaction vessel used for chemical raw materials described above has a top distillation column 4 that is directly connected to the inner cylinder, allowing for the simultaneous distillation and recovery of light components during the reaction process. This avoids the complex arrangement of external pipelines. The side nitrogen inlet 6 is also directly connected to the inner cylinder, enabling uniform nitrogen replacement of the cylinder area, enhancing the inert protection effect, and reducing the risk of oxidation and side reactions.

[0026] Furthermore, the rotating motor 2 is directly installed on the tank 1 through the central mounting hole and is coaxially connected to the agitator 3 through the reducer 7. This results in high transmission efficiency, a compact structure, and eliminates the energy loss and multiple seals required by traditional eccentric or bent shaft transmissions, reducing the risk of leakage and improving the uniformity of mixing and the reliability of the system.

[0027] In particular, the bottom ball valve outlet configuration enables one-click quick discharge, avoiding the tedious disassembly and assembly of threads or clamps, and allowing for more thorough cleaning. The machine has a high degree of integration, a small footprint, and simple piping, which facilitates rapid process switching and automated control, further improving production efficiency. Moreover, the reaction, distillation, inerting, stirring, and unloading functions are completed in the same vessel, significantly reducing equipment investment and maintenance costs, which meets the needs of modern chemical continuous and integrated production.

[0028] In this embodiment, the distillation column 4 is connected to the inlet side of the external condenser 9, and the outlet side of the condenser 9 is connected to a receiving tank 10 for waste gas storage. On one hand, the direct connection of the distillation column 4 to the inlet of the external condenser 9 shortens the vapor transport path, reduces heat loss, and improves the condensation efficiency and recovery rate of light components. On the other hand, the dedicated receiving tank 10 connected to the outlet side of the condenser 9 stores uncondensed waste gas components or light component tail gas, avoiding direct emission of waste gas and facilitating subsequent centralized treatment or reuse.

[0029] Preferably, the volume of the receiving tank 10 is smaller than that of the tank body 1, and the condenser 9 is inclined downwards from the tank body 1 to the receiving tank. The smaller volume of the receiving tank 10 reduces the space required, thus lowering the equipment footprint and material and manufacturing costs. Furthermore, the smaller volume of the receiving tank 10 allows for the concentration and collection of uncondensed gas, increasing the concentration of effective components in the waste gas for easier subsequent treatment or recovery. Additionally, the downward-inclined orientation of the condenser 9 from the tank body 1 to the receiving tank 10 allows gravity to cause the condensate to flow naturally down the pipe wall, reducing blockages and residues and ensuring continuous and stable liquid phase transport. The inclined angle enhances the countercurrent contact time of steam inside the condenser 9, facilitating more thorough heat exchange and improving the condensation rate.

[0030] Preferably, the distillation column 4 is arranged vertically below the condenser 9, and the receiving tank 10 extends vertically below the condenser 9. Thus, the distillation column 4, condenser 9, and receiving tank 10 are arranged along the same vertical line, forming a compact integrated vertical structure of "tower-cooler-tank", which significantly reduces the horizontal footprint and facilitates deployment in limited workshop space.

[0031] Specifically, the feed inlet 5 and the distillation column 4 are positioned on opposite sides of the mounting hole, and the feed inlet 5 is equipped with a manhole for easy inspection and maintenance. Arranging the feed inlet 5 and the distillation column 4 on opposite sides of the mounting hole avoids mutual interference between the feed and distillation pipelines, clearly separates different functional areas within the tank 1, simplifies pipeline routing, and reduces the risk of cross-contamination.

[0032] Obviously, the feed inlet 5 is designed as a manhole, allowing operators to directly enter the tank for inspection, cleaning or replacement of internal components, eliminating the tedious steps of overall disassembly and greatly shortening downtime for maintenance.

[0033] In this embodiment, the nitrogen inlet 6 extends horizontally outward on one side of the tank body 1. The tank body 1 is also provided with a wall-adhering channel 11 connecting the inner cylinder and the nitrogen inlet 6. The horizontal outward extension of the nitrogen inlet 6, combined with the wall-adhering channel 11, allows the inert gas to be evenly distributed along the inner wall of the tank body 1, preventing nitrogen from directly rushing to the center and creating a channel effect, thus ensuring that the inner cylinder and the entire vessel cavity are always in a uniform inert environment. Furthermore, the wall-adhering channel 11 is closely attached to the inner wall of the tank body 1, allowing nitrogen to flow along the wall and diffuse to various areas, reducing dead zones at the gas-liquid interface and helping to prevent localized oxidation or side reactions.

[0034] It should be mentioned that a temperature measuring port 12 for monitoring the nitrogen temperature is also provided between the wall-attached channel 11 and the tank body 1. The temperature measuring port 12 between the wall-attached channel 11 and the tank body 1 can directly measure the temperature of the introduced nitrogen, realize real-time monitoring of the inert atmosphere temperature, and help to accurately control the reaction and cooling conditions.

[0035] In this embodiment, the lower half of the tank 1 is provided with an outer shell 13 that can cover the inner cylinder, and the outer shell 13 is made of heat-insulating material. The heat-insulating outer shell covering the inner cylinder in the lower half effectively reduces heat loss from the bottom of the vessel, ensures stable temperature in the reaction zone, and improves heat utilization. In addition, the heat-insulating material significantly reduces the energy required for heating or heat preservation, shortens the heating time, and reduces the energy consumption for maintaining the temperature, thereby reducing operating costs.

[0036] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
