Description

Technical Field

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

[0002] Microwave reactor technology is applied to organic synthesis reactions, which can accelerate the reaction rate by tens or even thousands of times compared to conventional methods. It can also synthesize substances that are difficult to produce by conventional methods. It is being used more and more widely in materials, pharmaceuticals, chemical engineering and other related scientific research and teaching fields. Microwave reactors are required when carrying out organic synthesis reactions. In order to prevent the formation of reaction dead zones, the solution in the container needs to be stirred during the reaction.

[0003] Current microwave reactor stirring components use a stirring rod and a stirring shaft in combination. They are mainly used to stir solutions in wide-mouthed containers. However, solutions placed in narrow-mouthed bottles cannot be stirred when reacting in a microwave reactor, which may affect the reaction efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a stirring assembly for a microwave reactor that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stirring assembly for a microwave reactor includes: a mounting bracket disposed on the microwave reactor; a rotating tube rotatably disposed on the mounting bracket, with one end of the rotating tube extending into the microwave reactor and rotatably connected to the microwave reactor; a motor fixedly connected to the mounting bracket, with the output end of the motor fixedly connected to the rotating tube; a movable column disposed below the rotating tube; an electrically operated telescopic rod fixedly disposed between the movable column and the rotating tube; a first triangular prism fixedly disposed below the movable column; a plurality of rotating plates rotatably disposed on the first triangular prism; and a counterweight fixedly disposed at the lower end of the rotating plates.

[0007] To facilitate the resetting of the rotating plate, a second triangular prism is further fixedly connected to the lower side of the first triangular prism, and an elastic band is fixedly connected to the second triangular prism, with the upper end of the elastic band fixedly connected to the lower end of the rotating plate.

[0008] Furthermore, the second triangular prism is provided with multiple twisted surfaces, and when the rotating plate drives the elastic band to open, the elastic band is twisted.

[0009] Preferably, a sealing block matching the rotating tube is fixedly connected to the movable column.

[0010] To further improve the stirring efficiency of the solution in the container, a limiting groove and a receiving groove are further provided on the first triangular prism. A stirring rod is provided between the rotating plate and the limiting groove. Connecting rods are symmetrically fixed at both ends of the stirring rod. One of the connecting rods is slidably disposed in the limiting groove, and the other connecting rod is rotatably connected to the rotating plate.

[0011] To facilitate drainage and prevent residual solution in the container, a drain pipe is further provided between the container and the bottom of the second triangular prism.

[0012] Compared with the prior art, the present invention provides a stirring assembly for a microwave reactor, which has the following advantages:

[0013] 1. This microwave reactor uses a stirring assembly. The microcomputer on the microwave reactor adjusts the motor speed so that the diameter of the rotating plate when it opens is smaller than the inner diameter of the container. The motor drives the first and second triangular prisms to rotate through the rotating tube. Under the action of centrifugal force, the rotating plate opens and pulls the twisted elastic band to open. At this time, the rotating plate and the elastic band act as stirring elements to stir the raw materials in the container, thereby effectively improving the efficiency of the organic synthesis reaction, preventing the formation of reaction dead zones, and can also stir the solution in the container with a small opening. It has wide applicability.

[0014] 2. The microwave reactor uses a stirring assembly. When the rotating plate opens, the rotating plate pulls the stirring rod to move, causing the stirring rod to slide out of the limiting groove, thereby effectively improving the stirring effect on the solution in the container bottle.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention effectively improves the efficiency of organic synthesis reactions, prevents dead zones in the reaction, and can also stir the solution in the small-mouthed container, making it widely applicable.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Refer to Figures 1-5 A stirring assembly for a microwave reactor includes: a mounting bracket 1 disposed on the microwave reactor; a rotating tube 101 rotatably disposed on the mounting bracket 1, with one end of the rotating tube 101 extending into the microwave reactor and rotatably connected to the microwave reactor; a motor 102 fixedly connected to the mounting bracket 1, with the output end of the motor 102 fixedly connected to the rotating tube 101; a movable column 2 disposed on the lower side of the rotating tube 101; an electric telescopic rod 103 fixedly disposed between the movable column 2 and the rotating tube 101; a first triangular prism 3 fixedly disposed on the lower side of the movable column 2; multiple rotating plates 301 rotatably disposed on the first triangular prism 3; and a counterweight 302 fixedly disposed at the lower end of the rotating plates 301.

[0024] A second triangular prism 4 is fixedly connected to the lower side of the first triangular prism 3. An elastic band 402 is fixedly connected to the second triangular prism 4, and the upper end of the elastic band 402 is fixedly connected to the lower end of the rotating plate 301.

[0025] The second triangular prism 4 is provided with multiple twisted surfaces 401. When the rotating plate 301 drives the elastic band 402 to open, the elastic band 402 is twisted.

[0026] A sealing block 201 that matches the rotating tube 101 is fixedly connected to the movable column 2.

[0027] In the organic synthesis reaction of raw materials, the container containing the raw materials is placed in the microwave reactor with its mouth aligned with the rotating tube 101. The moving column 2 is pushed downward by the electric telescopic rod 103, and the first triangular column 3 and the second triangular column 4 enter the container. Then, the speed of the motor 102 is adjusted by the microcomputer on the microwave reactor so that the diameter of the rotating plate 301 when it opens is smaller than the inner diameter of the container. The motor 102 drives the first triangular column 3 and the second triangular column 4 to rotate through the rotating tube 101. Under the action of centrifugal force, the rotating plate 301 opens and pulls the twisted elastic band 402 to open. At this time, the rotating plate 301 and the elastic band 402 act as stirring elements to stir the raw materials in the container, thereby effectively improving the efficiency of the organic synthesis reaction, preventing the formation of reaction dead zones, and stirring the solution in the container with a small mouth. It has wide applicability.

[0028] After the reaction, the motor 102 is turned off to stop the rotation of the rotating tube 101, and the rotating plate 301 is reset under the action of the elastic belt 402.

[0029] Example 2: Refer to Figures 1-5 A stirring assembly for a microwave reactor is basically the same as in Example 1. Further, a limiting groove 303 and a receiving groove 304 are provided on the first triangular prism 3. A stirring rod 305 is provided between the rotating plate 301 and the limiting groove 303. Connecting rods 306 are symmetrically fixedly connected to both ends of the stirring rod 305. One of the connecting rods 306 is slidably disposed in the limiting groove 303, and the other connecting rod 306 is rotatably connected to the rotating plate 301.

[0030] A drain pipe 403 is provided between the receiving groove 304 and the bottom of the second triangular prism 4.

[0031] When the rotating plate 301 opens, it pulls the stirring rod 305 to move, causing part of the stirring rod 305 to slide out of the limiting groove 303, thereby effectively improving the stirring effect on the solution in the container bottle.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
