Description

Technical Field

[0001] This utility model relates to the field of chemical analysis, and in particular to a reaction apparatus for chemical analysis. Background Technology

[0002] In the field of chemical analysis, reaction apparatus is the core equipment for material mixing, reaction, and result detection, and its performance directly affects the accuracy and efficiency of analytical results. Especially in scenarios such as trace component analysis and reaction kinetic studies, it is necessary to precisely control the reaction environment through the apparatus to ensure that materials are in full contact and react according to the preset process. Therefore, efficient and stable reaction apparatus is of great significance for improving the quality of chemical analysis.

[0003] Most reaction apparatuses used in current chemical analysis are centered around a fixed container. During operation, the materials to be reacted are added to the container in sequence by hand. Some apparatuses are equipped with simple stirring components, which allow the materials to be mixed in one direction by manually rotating the stirring rod or starting a small stirring motor.

[0004] However, since traditional devices mostly use a single rotation or stirring mode, materials are prone to stratification or dead zones in the container. Especially for materials with large density differences, it is difficult to achieve sufficient contact, resulting in inconsistent reaction rates. Ultimately, this affects the repeatability and accuracy of the analytical results and cannot meet the needs of high-precision chemical analysis. Therefore, a chemical analysis reaction device is proposed to solve the above problems. Utility Model Content

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.

[0025] Reference Figure 1 - Figure 4This utility model provides an embodiment of a chemical analysis reaction apparatus, comprising a cylindrical body 1. A rotating mechanism 2 is provided on the inner wall of the cylindrical body 1. The rotating mechanism 2 includes a motor 21, which is fixedly mounted on the inner wall of the cylindrical body 1 to drive a first rotating rod 22 to rotate. The output end of the motor 21 is fixedly connected to the first rotating rod 22 to drive a first bevel gear 23 to rotate. The outer wall of the first rotating rod 22 is fixedly fitted with the first bevel gear 23 to drive a second bevel gear 25 to rotate. A second rotating rod 24 is rotatably passed through the bottom of the inner wall of the cylindrical body 1 to drive a turntable 26 to rotate. The outer wall of the second rotating rod 24 is fixedly fitted with the second bevel gear 25, and the second bevel gear 25 meshes with the first bevel gear 23 to drive the second rotating rod 24 to rotate. The top of the second rotating rod 24 is fixedly connected to... A turntable 26 is connected to the reactor. A positioning hole 27 is provided on the top of the turntable 26, so that the rotation of the turntable 26 can drive the reaction vessel 28 to rotate. The reaction vessel 28 is set on the top of the turntable 26. A positioning rod 29 is fixedly connected to the top of the reaction vessel 28, and the positioning rod 29 slides through the top of the positioning hole 27, so that the reaction vessel 28 can move up and down relative to the turntable 26. There are four positioning holes 27 and four positioning rods 29. The four positioning holes 27 are evenly arranged on the top of the turntable 26. A wave groove 210 is provided on the upper part of the inner wall of the cylinder 1. A sliding rod 211 is fixedly connected to the outer wall of the reaction vessel 28, and the bottom of the sliding rod 211 is slidably connected to the bottom of the inner wall of the wave groove 210, so that the reaction vessel 28 can shake up and down while rotating relative to the cylinder 1. A handle 212 is fixedly connected to the top of the reaction vessel 28 for easy removal of the reaction vessel 28.

[0026] Reference Figure 4 A swaying mechanism 3 is provided on the outer side of the cylinder 1. The swaying mechanism 3 includes a base 31, which is located below the cylinder 1. A bracket 32 ​​is fixedly connected to the top of the base 31 for supporting the cylinder 1. A rotating shaft 33 is fixedly connected to the outer wall of the cylinder 1. The rotating shaft 33 is rotatably connected to the bracket 32, allowing the cylinder 1 to sway relative to the bracket 32. A connecting rod 34 is fixedly connected to the inner side of the bracket 32 ​​for supporting the arc-shaped rack 35. An arc-shaped rack 35 is fixedly connected to one end of the connecting rod 34. A half gear 36 is fixedly sleeved at the bottom of the second rotating rod 24, and the half gear 36 meshes with the arc-shaped rack 35, allowing the cylinder 1 to sway while the second rotating rod 24 rotates. There are two arc-shaped racks 35, which are symmetrically arranged on both sides of the half gear 36. An anti-slip pad is fixedly connected to the bottom of the base 31.

[0027] Working principle: When the motor 21 is started, its output drives the first rotating rod 22 to rotate. The first bevel gear 23 on the outer wall of the first rotating rod 22 rotates accordingly. Since the first bevel gear 23 meshes with the second bevel gear 25 on the outer wall of the second rotating rod 24, the second bevel gear 25 drives the second rotating rod 24 to rotate, thereby causing the turntable 26 at the top of the second rotating rod 24 to rotate synchronously. The top of the turntable 26 engages with the positioning rod 29 at the top of the reaction vessel 28 through the positioning hole 27. When the turntable 26 rotates, it drives the reaction vessel 28 to rotate together. At the same time, the sliding rod 211 on the outer wall of the reaction vessel 28 slides in the wave groove 210 above the inner wall of the cylinder 1. The shape of the wave groove 210 affects the rotation of the rod. As the reaction vessel 28 rotates, it vibrates up and down, enhancing the mixing effect of the internal materials. When the second rotating rod 24 rotates, the half gear 36 at its bottom rotates synchronously. The half gear 36 meshes with the arc-shaped rack 35 at one end of the connecting rod 34 on the inner side of the support 32. The arc-shaped racks 35 on both sides alternately act with the half gear 36, pushing the cylinder 1 to swing left and right on the support 32 at the top of the base 31 with the rotating shaft 33 on its outer wall as the axis. This further improves the uniformity of the reaction of the materials in the reaction vessel 28. After the reaction is completed, the positioning rod 29 can be pulled out upwards through the handle 212 at the top of the reaction vessel 28 to disengage it from the positioning hole 27, thereby removing the reaction vessel 28 for subsequent operations.

[0028] It is worth noting that in this embodiment, the electrical equipment is a common device in the prior art, and the model used can be customized according to actual usage requirements.
