Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically to a high-efficiency stirred reaction vessel for chemical production. Background Technology

[0002] In chemical production, precise control of parameters such as stirring, temperature, and pressure is used to ensure the full reaction of chemical materials. Reactors are used to improve reaction efficiency and increase work efficiency. However, in practice, stirring alone is insufficient to improve work efficiency and can negatively impact chemical reaction efficiency.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application with application number CN202121939982.2 and application date of 2021-08-18) provides a stirred chemical reactor in which the stirring motor stirs the chemical raw materials through the stirring shaft, so that the centrifugal vortex fluid of the chemical raw materials at the bottom impacts the crushing device, which breaks up the agglomerated chemical raw materials. Compared with the existing structure, it not only facilitates the stirring and mixing of chemical raw materials, but also facilitates the crushing of the agglomerated chemical raw materials at the bottom, thereby improving the reaction efficiency. While existing technologies can complete chemical reactions, it is inconvenient to fully stir them during operation, which can easily lead to a low mixing reaction rate of materials and affect the chemical reaction effect. Furthermore, stirring alone is insufficient for mixing gases to carry out the reaction when aeration or other reactions are required.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing high-efficiency stirred reactors used in chemical production. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency stirred reactor for chemical production, in order to solve the problems mentioned in the background art, such as the inconvenience of sufficient stirring during operation, which easily leads to a low mixing reaction rate of materials, affecting the chemical reaction effect, and the difficulty in mixing gases for reaction work when gasification or other reactions are required, simply by stirring.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency stirred reactor for chemical production, comprising a reaction vessel and a cover assembled on the upper surface of the reaction vessel; including: a rotating shaft, rotating on the lower side of the inner surface of the cover, with a stirring shaft mounted on the lower surface of the rotating shaft, and a stirring element mounted on the outer surface of the stirring shaft, while a flow divider is mounted on the outer surface of the stirring element, and a through hole is opened on the inner surface of the stirring shaft, and a bottom rod is mounted on the outer surface of the rotating shaft, while a diagonal brace is obliquely mounted between the bottom rod and the rotating shaft, and a turntable is mounted on the upper side of the outer surface of the rotating shaft, and the turntable is connected to a telescopic component through a compression telescopic mechanism, while the telescopic component is connected to an external ring through an alternating ventilation mechanism, and an exhaust pipe is mounted on the upper surface of the cover.

A telescopic rod is installed on the outer surface of the slider, and an extrusion plate is installed on the outer surface of the telescopic rod. The telescopic rod and the extrusion plate are slidably connected to a telescopic assembly, and the telescopic assembly is installed on the inner surface of the cover.

[0009] Preferably, the turntable and the rotating shaft form an integrated structure, and the turntable forms a limiting sliding structure with the slider through the sliding groove, and the slider and the telescopic rod form an integrated structure, while the telescopic rod is embedded in the outer surface of the extrusion plate.

[0012] Preferably, the telescopic component forms an integrated structure with the air inlet pipe and the air outlet pipe, and the air outlet pipe is embedded in the outer surface of the outer ring. The outer ring is positioned and rotated with the stirring shaft through the inner ring, while the stirring shaft forms a ventilation structure with the air outlet pipe through the air delivery groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-6 The present invention provides the following technical solution: a high-efficiency stirred reaction vessel for chemical production, which is provided with a reaction vessel 1 and a cover 2 assembled on the upper surface of the reaction vessel 1.

[0020] Example 1: As Figures 1-6 The present invention provides the following technical solution: a high-efficiency stirred reactor for chemical production, comprising: a rotating shaft 3, rotating on the lower side of the inner surface of the cover 2, and a stirring shaft 6 installed on the lower surface of the rotating shaft 3, and a stirring element 4 installed on the outer surface of the stirring shaft 6, and a flow divider 5 installed on the outer surface of the stirring element 4, and a through hole 7 opened on the inner surface of the stirring shaft 6, and a bottom rod 8 installed on the outer surface of the rotating shaft 3, and a diagonal brace 9 installed obliquely between the bottom rod 8 and the rotating shaft 3, and a turntable 10 installed on the upper side of the outer surface of the rotating shaft 3, and the turntable 10 is connected to a telescopic component 15 through a compression telescopic mechanism, and the telescopic component 15 is connected to an external ring 18 through an alternating ventilation mechanism, and an exhaust pipe 22 is installed on the upper surface of the cover 2.

[0021] During use, the stability of chemical material delivery is controlled through the feed inlet on the cover 2 assembled in the reaction vessel 1. The motor installed on the cover 2 drives the rotating shaft 3 assembled on the output shaft to rotate, thereby controlling the coaxial rotation of the stirring shaft 6 installed on the rotating shaft 3. The flow divider 5 assembled on the stirring component 4 installed on the stirring shaft 6 can divert and fully stir the incoming chemical material. The holes in the stirring component 4 can improve the diversion reaction effect and increase the dispersion effect. When the stirring shaft 6 passes through, the diagonal brace 9 installed on the bottom rod 8 can improve the stability of the bottom rod 8 assembly and prevent the accumulation at the bottom of the reaction vessel 1, so as to ensure full reaction. In conjunction with the rotation of the rotating shaft 3, the position of the extrusion plate 14 of the turntable 10 is adjusted, thereby controlling the gas delivery effect. In conjunction with the external ring 18 connected to the telescopic component 15, the gas is delivered to the gas delivery trough 21, and then vented through the through hole 7 opened on the stirring shaft 6 to improve the chemical reaction effect. Different gases can be delivered according to the chemical reaction requirements, and when the chemical reaction is not required, inert gas can be introduced to improve the reaction effect.

[0022] Example 2: Figures 1-4The technical solution shown, based on Embodiment 1, further discloses increasing the stirring effect through diversion and further increasing the reaction effect through a compression and telescopic mechanism. This solves the problem that during operation, it is inconvenient to perform thorough stirring, which easily leads to a low mixing reaction rate and affects the chemical reaction effect. The specific details are as follows: The cover 2 forms a coaxial rotating structure with the stirring shaft 6 via the rotating shaft 3, and the rotating shaft 3, stirring shaft 6, and stirring component 4 form an integrated structure. The stirring component 4 is embedded in the outer surface of the diversion component 5, while the stirring shaft 6, bottom rod 8, and diagonal brace 9 form an integrated structure. Figure 3 and Figure 4 As shown, the extrusion telescopic mechanism also includes a groove 11 formed on the outer surface of the turntable 10, and a slider 12 is slidably connected to the outer surface of the groove 11. A telescopic rod 13 is mounted on the outer surface of the slider 12, and an extrusion plate 14 is mounted on the outer surface of the telescopic rod 13. A telescopic assembly 15 is slidably connected to the telescopic rod 13 and the extrusion plate 14, and the telescopic assembly 15 is mounted on the inner surface of the cover 2. Figure 3 and Figure 4 As shown, the turntable 10 and the rotating shaft 3 form an integrated structure, and the turntable 10 and the slider 12 form a limiting sliding structure through the slide groove 11. The slider 12 and the telescopic rod 13 form an integrated structure, and the telescopic rod 13 is embedded in the outer surface of the extrusion plate 14. Figure 3 and Figure 4 As shown, the extrusion plate 14 and the telescopic component 15 constitute a sliding extrusion structure, and the telescopic component 15 is symmetrically embedded in the inner surface of the cover 2.

[0023] In use, the stirring component 4 and the flow divider 5 installed on the stirring shaft 6 assembled by the rotating shaft 3 are used for full stirring. When the rotating shaft 3 rotates, the rotation of the turntable 10 controls the sliding groove 11 and the slider 12 to slide and squeeze. The sliding adjustment slider 12 is installed on the telescopic rod 13 and the extrusion plate 14 installed on the telescopic rod 13 slides and limits the sliding on the inner surface of the telescopic assembly 15, thereby controlling the telescopic assembly 15 to carry in and out of gas, thereby controlling the stability of gas delivery.

[0024] Example 3: Figure 5 and Figure 6The technical solution shown, based on Embodiment 2, further discloses the ability to introduce different gases as needed to enhance the reaction effect. This solves the problem that it is difficult to mix gases for reaction when gasification or other reactions are required by stirring alone. The specific details are as follows: The alternating ventilation mechanism also includes an inlet pipe 16 mounted on the upper surface of the telescopic component 15, and an outlet pipe 17 mounted on the lower surface of the telescopic component 15. An outer ring 18 is mounted on the outer surface of the outlet pipe 17, and a support rod 19 is mounted on the outer surface of the outer ring 18. The support rod 19 is positioned and mounted on the inner surface of the cover 2. An inner ring 20 is rotatably connected to the inner surface of the outer ring 18 and is mounted on the stirring shaft 6. A gas delivery groove 21 is opened on the upper side of the stirring shaft 6, and the gas delivery groove 21 is nested with the outer ring 18. An exhaust pipe 22 is mounted on the upper surface of the cover 2. Figure 5 and Figure 6 As shown, the telescopic component 15, the air inlet pipe 16, and the air outlet pipe 17 form an integrated structure. The air outlet pipe 17 is embedded in the outer surface of the outer ring 18. The outer ring 18 is positioned and rotated with the stirring shaft 6 through the inner ring 20. At the same time, the stirring shaft 6 is connected to the air outlet pipe 17 through the air delivery groove 21 to form a ventilation structure.

[0025] When the extrusion plate 14 installed on the telescopic rod 13 slides inside the telescopic assembly 15, the control gas enters through the inlet pipe 16 and exits through the outlet pipe 17 installed on the lower side of the telescopic assembly 15. The gas is then vented through the outer ring 18 installed on the outlet pipe 17 and transported to the stirring shaft 6 of the outer ring 18. The gas is then stably output to the reaction vessel 1 through the through hole 7 opened on the stirring shaft 6. The stirring shaft 6 installed on the rotating shaft 3 needs to rotate. To prevent affecting the normal rotation of the stirring shaft 6, the gas delivery groove 21 opened on the stirring shaft 6 and the nesting between the inner ring 20 installed on the stirring shaft 6 and the outer ring 18, along with the support rod 19 installed on the outer ring 18, are stably assembled on the lower side of the cover body 2. This controls the stability of the outer ring 18 and the gas delivery, increases the chemical reaction effect, and controls the reaction vessel to carry out efficient stirring reaction.

[0026] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
