Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of reaction vessel technology, and more specifically to a high-efficiency mixing reaction vessel. Background Technology
[0002] Double-walled glass reactors are commonly used laboratory instruments, widely applied in fine chemical engineering and new material synthesis. By injecting high-temperature or low-temperature liquid media into the jacket of the reactor, materials within can be heated or cooled at a constant temperature. A typical glass reactor consists of a vessel body, a stirring system, a heating and cooling system, and inlet / outlet ports. Because the vessel body is a cylindrical tube, the smooth, rounded inner wall of the inner liner results in strong, unimpeded liquid flow during mixing, limiting the mixing effect and reducing efficiency. To address this, a method is proposed to install equidistant protrusions or grooves within the inner liner of the reactor. These protrusions increase shear force during mechanical stirring, shortening the mixing time of the liquid materials to meet practical application needs.
[0003] Traditional reactors often have significant limitations in mixing operations. For example, the mixing effect of common impeller reactors relies heavily on the type and rotation speed of the impeller. In reactions involving high-viscosity materials, the material around the impeller mixes well, but areas further away from the impeller experience poor mixing, leading to uneven mixing, incomplete reactions, or unstable product quality. Furthermore, due to the limited range of motion of the impeller, large-scale reactors require a considerable amount of time to achieve an ideal mixing state, thus reducing production efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency mixing reactor. By installing the reactor mechanism and the mounting mechanism, the reactor increases shear force, improves uniformity during stirring, and increases production efficiency, thereby solving the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A high-efficiency mixing reactor, including
[0007] The mounting mechanism is equipped with the reactor mechanism.
[0008] The reactor structure includes a double-layered glass vessel body. The bottom of the double-layered glass vessel body is equipped with a discharge valve, and the inner wall is provided with multiple cylinders in a ring shape. The top is equipped with a top cover, and the upper end of the top cover is connected to a constant pressure dropping funnel, a motor and a connecting pipe.
[0009] As a further technical solution of this utility model, the top cover is connected to the double-layer glass vessel body by two fixed sealing rings. The two fixed sealing rings are arranged vertically, with the upper fixed sealing ring connected to the top cover and the lower fixed sealing ring connected to the double-layer glass vessel body. The upper fixed sealing ring is provided with multiple fixing bolts, which fix the position of the two fixed sealing rings.
[0010] As a further technical solution of this utility model, the motor is mounted on a motor mounting bracket, the end of the motor is connected to a rotating rod, and a stirring paddle is installed at the bottom of the rotating rod.
[0011] As a further technical solution of this utility model, a stirring baffle is fixedly installed inside the double-layer glass vessel, and the stirring baffle is provided with multiple round holes.
[0012] As a further technical solution of this utility model, the other end of the connecting tube is connected to the reflux bottle, the upper end of the reflux bottle is provided with a condenser tube, the reflux bottle and the condenser tube are fixed on the stainless steel frame by a bracket, each of the four corners of the bottom of the stainless steel frame is provided with a caster wheel, and a vessel mounting bracket is installed on the stainless steel frame. The vessel mounting bracket is connected to the bottom of the double-layer glass vessel, and a frequency converter digital display speed controller is installed at the upper end of the stainless steel frame. The motor mounting bracket is also located on the stainless steel frame.
[0013] As a further technical solution of this utility model, a C-shaped support block 216 with an upward opening is integrally formed at the bottom of the double-layer glass vessel body 21, and there are two symmetrical sets of C-shaped support blocks 216. Two symmetrical sets of limiting blocks 217 are fixedly installed at the bottom of the stirring baffle 213, and there are two limiting blocks 217 in each set. The C-shaped support block 216 is located between the two limiting blocks 217 to perform a limiting function.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. In use, the motor drives the rotating rod to rotate, which in turn drives the stirring paddle to rotate. The inner wall of the double-layered glass vessel is provided with multiple cylinders in a ring shape. When the stirring paddle drives the material inside the double-layered glass vessel to rotate, the cylinders inside the double-layered glass vessel can effectively increase the shearing force, shorten the mixing time, improve the heat transfer efficiency, reduce the cost, and make it easy to clean. At the same time, since no additional devices are needed to increase the shearing force, the operation is simple, easy to clean, and shortens the working time.
[0016] 2. In this invention, a stirring baffle is fixedly installed inside the double-layered glass vessel. The stirring baffle obstructs the solution during stirring, causing the solution inside the double-layered glass vessel to no longer exhibit a vortex-like pattern, but instead to generate turbulence on the side of the stirring baffle. This increases the dissolution efficiency and shortens the experimental stirring time. At the same time, multiple round holes are provided on the stirring baffle to reduce the resistance and centrifugal force of the liquid during the baffle's movement, which could lead to deformation or breakage of the stirring baffle, thus greatly shortening the material mixing time.

Detailed Implementation
[0027] 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.
[0028] Please see Figure 1-7 In this embodiment of the present invention, a high-efficiency mixing reactor includes an installation mechanism 1 on which a reactor mechanism 2 is installed;
[0029] The reactor mechanism 2 includes a double-layered glass reactor body 21. The bottom of the double-layered glass reactor body 21 is provided with a discharge valve 22, the inner wall is provided with a plurality of cylinders 215 in a ring shape, and the top is provided with a top cover 23. The upper end of the top cover 23 is connected to a constant pressure dripping funnel 26, a motor 27 and a connecting pipe 28 respectively.
[0030] By adopting the above technical solution, during use, the motor 27 drives the rotating rod 211 to rotate, and the rotating rod 211 simultaneously drives the stirring paddle 212 to rotate. The inner wall of the double-layer glass vessel 21 is provided with multiple cylinders 215 in a ring shape. When the stirring paddle 212 drives the material inside the double-layer glass vessel 21 to rotate, the cylinders 215 inside the double-layer glass vessel 21 can effectively increase the shearing force, shorten the mixing time, improve the heat transfer efficiency, reduce costs, and make it easy to clean. At the same time, since no additional devices are needed to increase the shearing force, the operation is simple, easy to clean, and the working time is shortened.
[0031] In this embodiment, the top cover 23 is connected to the double-layer glass vessel body 21 by two fixing sealing rings 24. The two fixing sealing rings 24 are arranged vertically, with the upper fixing sealing ring 24 connected to the top cover 23 and the lower fixing sealing ring 24 connected to the double-layer glass vessel body 21. The upper fixing sealing ring 24 is provided with multiple fixing bolts 25, which fix the position of the two fixing sealing rings 24 by fixing bolts 25.
[0032] The motor 27 is mounted on the motor mounting bracket 16, and the end of the motor 27 is connected to the rotating rod 211. The bottom of the rotating rod 211 is equipped with a stirring paddle 212.
[0033] A stirring baffle 213 is fixedly installed inside the double-layer glass vessel body 21, and the stirring baffle 213 is provided with a plurality of round holes 214;
[0034] The other end of the connecting pipe 28 is connected to the reflux bottle 29. The upper end of the reflux bottle 29 is provided with a condenser tube 210. The reflux bottle 29 and the condenser tube 210 are fixed on the stainless steel frame 12 by the bracket 15. The bottom four corners of the stainless steel frame 12 are each provided with a caster wheel 11. The stainless steel frame 12 is also equipped with a vessel mounting bracket 13. The vessel mounting bracket 13 is connected to the bottom of the double-layer glass vessel 21. The upper end of the stainless steel frame 12 is equipped with a frequency converter digital display speed controller 14. The motor fixing bracket 16 is also provided on the stainless steel frame 12.
[0035] The double-layered glass vessel body 21 has an integrally formed C-shaped support block 216 with the opening facing upward at the bottom of the interior. There are two symmetrical sets of C-shaped support blocks 216. The bottom of the stirring baffle 213 is fixedly installed with two symmetrical sets of limiting blocks 217. There are two limiting blocks 217 in each set. The C-shaped support block 216 is located between the two limiting blocks 217 to limit the movement.
[0036] By adopting the above technical solution, the interior of the double-layered glass vessel 21 is integrally formed with an upward-facing C-shaped support block 216. At the same time, a limiting block 217 is set at the bottom of the stirring baffle 213. When installing the stirring baffle 213, two limiting blocks 217 are engaged between the upward-facing C-shaped support blocks 216. The stirring baffle 213 is limited by the action of the two sets of structures, so that the stirring baffle 213 cannot move in its original position. Due to its fixed installation structure, the stirring baffle 213 obstructs the solution in the stirring process, so that the solution in the double-layered glass vessel 21 no longer presents a vortex, but generates turbulence on the side of the stirring baffle 213, which increases the dissolution efficiency and shortens the experimental stirring time. At the same time, multiple round holes 214 are provided on the stirring baffle 213 to reduce the resistance of the liquid and centrifugal force on the stirring baffle 213 during the reduction of the plate, which may cause the stirring baffle 213 to deform or break, and greatly shorten the material mixing time.
[0037] The working principle of this utility model is as follows: When in use, the motor 27 drives the rotating rod 211 to rotate, and the rotating rod 211 simultaneously drives the stirring paddle 212 to rotate. The inner wall of the double-layer glass vessel 21 is provided with multiple cylinders 215 in a ring shape. When the stirring paddle 212 drives the material inside the double-layer glass vessel 21 to rotate, the cylinders 215 inside the double-layer glass vessel 21 can effectively increase the shearing force, shorten the mixing time, improve the heat transfer efficiency, reduce the cost, and make it easy to clean. At the same time, since no additional devices are needed to increase the shearing force, the operation is simple, easy to clean, and the working time is shortened.
[0038] A stirring baffle 213 is fixedly installed inside the double-layered glass vessel 21. An upward-facing C-shaped support block 216 is integrally formed inside the double-layered glass vessel 21. A limiting block 217 is provided at the bottom of the stirring baffle 213. During installation, two limiting blocks 217 are engaged between the upward-facing C-shaped support blocks 216. The stirring baffle 213 is limited by these two sets of structures, preventing it from moving in its original position. Due to its fixed installation, the stirring baffle 213 obstructs the solution during stirring, causing the solution inside the double-layered glass vessel 21 to no longer swirl, but instead generate turbulence on the side of the stirring baffle 213. This increases dissolution efficiency and shortens the experimental stirring time. Furthermore, multiple round holes 214 are provided on the stirring baffle 213 to reduce the resistance and centrifugal force experienced by the liquid during plate reduction, thus preventing deformation or breakage of the stirring baffle 213 and significantly shortening the material mixing time.
