Description

Technical Field

[0001] This utility model relates to the field of reactor component technology, and in particular to a reactor stirring mechanism. Background Technology

[0002] There are many types of chemical raw materials with a wide range of uses. There are as many as 5 to 7 million kinds of chemicals in the world, and more than 100,000 kinds are sold and circulated on the market. In addition, more than 1,000 new chemicals are launched every year. In recent years, the consumption of chemical raw materials has increased dramatically. In the chemical production process, after the materials are put into the reaction vessel, it is usually necessary to use a stirring mechanism to stir the materials.

[0003] Currently, existing reactor stirring mechanisms, such as Chinese Patent Publication No. CN216149732U, disclose a reactor stirring mechanism for processing methyl amidate. This mechanism includes a horizontally mounted servo motor at the top of the reactor, a pad fixedly installed between the bottom of the servo motor and the curved wall of one side of the reactor, and the output end of the servo motor extending into the reactor cavity via a bearing through the pad and the reactor wall. A vertically downward rotating rod is fixedly connected to the output end of the servo motor, positioned eccentrically within the reactor cavity. A stirring assembly driven by the rotating rod is installed within the reactor cavity. The stirring assembly includes a travel sleeve and a stirring plate. The mixing plate is a hollow cylinder, fixedly installed between the upper and lower stroke sleeves. The upper stroke sleeve is fixedly installed on the bottom wall of the rotating rod. Each stroke sleeve cavity is equipped with a stirring crossbar that can be squeezed. By setting the mixing plate and the stepped rod, the mixing plate in the reactor cavity presents a wave-like shape from top to bottom, so that the rotating rod drives the mixing plate to rotate and stir the reaction material in the reactor cavity, improving the stirring efficiency and frequency of the reaction material. However, in actual use, the stirred material in the reactor will have a certain impact on the stirring mechanism. After long-term use, the complex stirring mechanism of the above device often requires frequent maintenance and repair, which is inconvenient to use.

[0004] How to quickly and efficiently mix materials in a reactor while ensuring the strength of the stirring mechanism, and improve the mixing effect, has become a technical problem that needs to be solved.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] To address the aforementioned shortcomings, the purpose of this invention is to provide a reaction vessel stirring mechanism that has a simple structure and can quickly and efficiently stir and mix the materials in the reaction vessel while ensuring the strength of the stirring mechanism, thereby improving the mixing effect.

[0007] To achieve the above objectives, this utility model provides a reaction vessel stirring mechanism, including a rotatable rotating shaft, on which a plurality of collars are sleeved, and at least two sets of stirring components are provided circumferentially on the outside of the collars.

[0010] According to the reaction vessel stirring mechanism of this utility model, several fixing strips are symmetrically arranged on the movable plate, and each fixing strip has a pointed end near the fixing plate.

[0014] According to the reaction vessel stirring mechanism of this utility model, the rotating shaft is rotatably connected to the inside of the reaction vessel, and a driving component is provided on the outside of the reaction vessel, the driving component being connected to the rotating shaft.

[0015] The purpose of this invention is to provide a stirring mechanism for a reaction vessel, including a fixed plate and a movable plate. When materials impact the movable plate, the movable plate can disperse the materials, creating turbulence within the reaction vessel, thereby quickly and efficiently stirring and mixing the materials in the reaction vessel, improving the mixing effect. Each stirring assembly has at least one stabilizing rod between the two fixed plates and the movable plate.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] See Figures 1-3 This utility model provides a stirring mechanism for a reaction vessel, including a rotating shaft 1, which is rotatably connected to the inside of a reaction vessel (not shown in the figure). A driving component is provided on the outside of the reaction vessel, and the output shaft of the driving component passes through the inside of the reaction vessel and connects to the rotating shaft 1. The driving component can drive the rotating shaft 1 to rotate. The structure and working principle of the rotating shaft 1 are the same as the stirring shaft of the reaction vessel in the prior art. The specific connection method will not be described in detail here. Several collars 2 are sleeved on the rotating shaft 1. All collars 2 can rotate with the rotating shaft 1. At least two sets of stirring components are provided on the outside of the collars 2 along the circumference. The stirring components are evenly distributed along the circumference of the collars 2 (the interval between two adjacent sets of stirring components is the same).

[0024] See Figures 1-3Each stirring assembly includes symmetrically arranged fixed plates 21. The fixed plates 21 are cuboid structures. A movable plate 22 is provided between the two fixed plates 21. The end of the movable plate 22 near the collar 2 is hinged to the collar 2. The movable plate 22 can rotate to the side closer to or away from the fixed plate 21. At least one stabilizing rod 3 is provided between the two fixed plates 21 and the movable plate 22 of each stirring assembly. The stabilizing rod 3 includes an outer rod 31 connected to the fixed plate 21. An inner rod 32 is elastically connected inside the outer rod 31 (the inner rod 32 inside the outer rod 31 is symmetrically provided with a plug, and the outer rod 31 is provided with a slot that cooperates with the plug. The plug is slidably set in the slot, and an elastic element 33 is provided between the plug and the slot). The end of the inner rod 32 near the movable plate 22 extends out of the outer rod 31 and connects to the movable plate 22. When the material in the reactor comes into contact with the movable plate 22, the stabilizing rod 3 can improve the stability of the movable plate 22.

[0025] See Figures 1-3 Preferably, the elastic element 33 is a spring, which provides return power.

[0026] See Figures 1-3 Preferably, the fixed plate 21 is provided with several through holes 211, and the material in the reactor can pass through the through holes 211 to impact the movable plate 22, thereby further improving the mixing effect.

[0027] See Figures 1-3 Preferably, the movable plate 22 is symmetrically provided with a number of fixing strips 221. The end of the fixing strip 221 near the fixing plate 21 is provided with a tip (the tip is the end with a ridge). When the material in the reactor passes through the through hole 211 and hits the movable plate 22, the fixing strip 221 can contact the material, break up the material, and improve the mixing effect.

[0028] See Figures 1-3 The rotating shaft 1 is rotated, which drives the collar 2 to rotate. The collar 2 drives the fixed plate 21 and the movable plate 22 to rotate. Due to the impact of the material on the movable plate 22, the movable plate 22 undergoes a small-amplitude rotational vibration, which disperses the material and forms turbulence in the reactor, thereby accelerating the mixing of the material.

[0029] This invention provides a stirring mechanism for a reaction vessel, including a fixed plate and a movable plate. When material impacts the movable plate, the movable plate disperses the material, creating turbulence within the reaction vessel. This rapidly and efficiently stirs and mixes the material, improving the mixing effect. Each stirring assembly has at least one stabilizing rod between the two fixed plates and the movable plate. Each stabilizing rod includes an outer rod connected to the fixed plate, and an inner rod elastically connected to the outer rod. When the material in the reaction vessel contacts the movable plate, the stabilizing rod enhances the stability of the movable plate and strengthens the stirring mechanism. In summary, the beneficial effects of this invention are: it can rapidly and efficiently stir and mix the material in the reaction vessel while ensuring the strength of the stirring mechanism, thus improving the mixing effect.

[0030] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
