Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a homogenized stirred chemical reaction vessel. Background Technology

[0002] A reaction vessel is a comprehensive reaction container, widely used in production users such as petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries, as well as in various scientific research projects. As the core component inside the reaction vessel, the stirrer disperses two or more different substances during the material mixing and reaction process, thereby achieving uniform mixing and full reaction, while accelerating heat and mass transfer.

[0003] After long-term use, existing reactors are prone to leakage problems due to poor sealing of the discharge section caused by centrifugal force from stirring. Vibration and leakage problems can also lead to equipment damage and maintenance difficulties, which are the main reasons for replacing reactors.

[0004] Therefore, we propose a homogeneous stirred chemical reactor. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a homogenized stirred chemical reactor to avoid equipment damage caused by poor sealing of the discharge section, medium leakage, and excessive vibration.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A homogenizing stirred chemical reactor includes a reactor body and a base. A connecting hole is located at the center of the bottom end of the reactor body, and a sealing cover is located at the top end of the reactor body. A stirring rod is movably mounted on the inner wall of the reactor body, and a sealing disc is located at the bottom end of the stirring rod. Several feed inlets are located on the surface of the sealing disc, and a guide pipe is located at the bottom end of the sealing disc. A straight insertion pipe is located at the top end of the base, passing through the connecting hole and threadedly connected to it. The straight insertion pipe is also threadedly connected to the guide pipe. A discharge pipe is located on one side of the base, and the discharge pipe communicates with the straight insertion pipe. It is worth noting that the sealing disc and the stirring rod are only engaged; the sealing disc cannot be rotated. Furthermore, when the sealing disc is engaged with the connecting hole, a gasket can be optionally added to the bottom end of the sealing disc to reduce friction. While adding a gasket does not affect leakage (because the straight insertion pipe forms a seal during the threaded connection with the connecting hole), it indirectly affects the feed rate at the feed inlets and the outflow rate of the medium at the bottom of the reactor body.

[0008] As a further embodiment of this utility model: the top of the base is engaged with the bottom of the vessel body, stirring arms are provided on both sides of the stirring rod, and a few turbulence plates are provided at the bottom of the stirring arms.

[0009] As a further improvement of this utility model: the sealing cover is threadedly connected to the vessel body, and a stepper motor is provided at the top of the sealing cover. The motor shaft of the stepper motor is connected to the top of the stirring rod through a coupling.

[0010] As a further improvement of this utility model: stable supports are provided on both sides of the stirring arm, and a circumferential groove is opened on the inner wall of the vessel body, with the stable support passing through the circumferential groove and engaging.

[0011] As a further embodiment of this invention: the bottom end of the stirring arm is provided with several connecting bearings, the connecting bearings are connected to the top of the baffle plate, several flow-disrupting grooves are formed on both sides of the baffle plate, and several flow-disrupting holes are formed on the surface of the baffle plate. As a further embodiment of this invention: an electric heating plate is provided at the bottom of the inner wall of the vessel body, and several flow-guiding grooves are formed on the surface of the electric heating plate, the flow-guiding grooves surrounding the outside of the connecting hole.

[0012] As a further improvement of this utility model: the top of the base is provided with several fixing grooves, the bottom of the vessel is provided with several fixing rods, the fixing rods are surrounded around the outside of the connecting hole, the fixing grooves correspond to and engage with the fixing rods, and the four corners of the bottom of the base are provided with elastic supports.

[0013] Compared with the prior art, this utility model provides a homogenized stirred chemical reaction vessel, which has the following beneficial effects:

[0014] 1. In this utility model, the sealing cover is threadedly connected to the vessel body, and the straight insertion tube is threadedly connected to the connecting hole and the guide pipe respectively. The multi-threaded sealing design can reduce the risk of material leakage and avoid leakage caused by the vibration of the machine body during the stirring process. At the same time, the stirring area is always separated from the discharge part by means of the threaded seal, which avoids the minor leakage caused by long-term use of traditional stirring vessel bodies.

[0015] 2. In this utility model, stirring arms are provided on both sides of the stirring rod. The bottom end of the stirring arms is connected to a bearing and equipped with a baffle plate with multiple sets of turbulence grooves. The baffle plate is engaged with the stable support on both sides of the stirring arm through the grooves around the vessel body, which can prevent shaking during stirring. At the same time, the turbulence grooves can break up the material layer and improve the uniformity of stirring. Furthermore, the baffle plate connected to the bearing is also pushed by the flowing medium to rotate when the stirring arms rotate, thus creating a turbulence effect and avoiding stirring in one direction, making the mixing more uniform.

[0016] 3. In this utility model, the top of the base is engaged with the bottom of the vessel body by a fixing groove, thereby achieving lateral stability between the vessel body and the base. The four corners of the bottom of the base are provided with elastic supports, which can buffer the vibration during stirring and reaction, and improve the overall stability.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

Several turbulence plates 12 are provided at the bottom end of the stirring arms 11. The sealing cover 4 is threaded to the vessel body 1. The straight insertion pipe 9 is threaded to the connection hole 3 and the guide pipe 8, respectively. The multi-threaded sealing design can reduce the risk of material leakage and avoid leakage caused by machine vibration during stirring.

[0027] like Figure 1 - Figure 4 As shown, the sealing cover 4 is threadedly connected to the vessel body 1. A stepper motor 13 is installed at the top of the sealing cover 4. The motor shaft of the stepper motor 13 is connected to the top of the stirring rod 5 through a coupling. Stable supports 14 are provided on both sides of the stirring arm 11. A surrounding groove 15 is opened on the inner wall of the vessel body 1. The stable supports 14 pass through the surrounding groove 15 and are engaged. Several connecting bearings 16 are provided at the bottom of the stirring arm 11. The connecting bearings 16 are connected to the top of the baffle plate 12. Several turbulence channels 17 are opened on both sides of the baffle plate 12. Several turbulence channels 23 are opened on the surface of the baffle plate 12.

At the same time, the turbulence channels 17 can break the material layer and improve the uniformity of stirring.

[0028] like Figure 1 - Figure 3 As shown, an electric heating plate 18 is provided at the bottom of the inner wall of the vessel body 1. Several guide grooves 19 are opened on the surface of the electric heating plate 18. The guide grooves 19 surround the outside of the connection hole 3.
