Description

Technical Field

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

[0002] A chemical reaction is the process by which molecules break down into atoms, and these atoms rearrange and recombine to form new molecules. Reactions are often accompanied by phenomena such as light emission, heat generation, color change, and the formation of precipitates. The criterion for determining whether a reaction is a chemical reaction is whether or not new molecules are formed.

[0003] In chemical analysis, appropriate reaction apparatus is required. An existing chemical analysis reaction apparatus, such as one described in patent publication number CN214382706U, allows for setting the stirring speed during experiments through a stirrer and control panel. This solves the problem that existing apparatuses cannot maintain a constant stirring speed for experimental materials as needed. Furthermore, the control panel allows for position adjustment of the stirrer in front of the functional column, addressing the issue that operators often find it difficult to immediately operate the apparatus after it has been heated, hindering data collection. The apparatus also features a reaction chamber and a setting plate. The setting plate allows for setting the heating stability of the reaction chamber as needed, enabling constant temperature heating. This solves the safety issues associated with the use of open flames such as alcohol lamps in existing reaction apparatuses, which result in uncontrollable temperature control. Additionally, the apparatus is configured with two sets for control experiments, reducing experimental errors.

[0004] However, the device has difficulty in accurately controlling the amount of chemical raw materials added, which leads to errors in the reaction and poor reliability. Utility Model Content

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.

[0024] Example

[0025] Please see Figures 1-4A chemical analysis reaction apparatus includes a reaction vessel 1, a connecting frame 1 2, a hopper 3, a small on / off valve 4, a discharge head 1 5, a connecting frame 2 6, a central rotating cylinder 7, a piston 8, a connecting rod 9, a push-pull plate 10, a feed pipe 11, a discharge head 2 12, and a graduation strip 24. The front top of the reaction vessel 1 is connected to the middle front of the hopper 3 via the connecting frame 1 2. A graduation strip 24 is also provided inside the hopper 3. The bottom of the hopper 3 is connected to the top of the small on / off valve 4, and the bottom of the small on / off valve 4 is connected to the top of the discharge head 1 5. The rear top of the reaction vessel 1 is connected to the lower rear end of the central rotating cylinder 7 via the connecting frame 2 6. The input end of the central rotating cylinder 7 is connected to the inside of the feed pipe 11, and the output end of the central rotating cylinder 7 is connected to the inside of the discharge head 2 12. The inside of the central rotating cylinder 7 is slidably connected to the outside of the piston 8. The middle top of the piston 8 is connected to the middle bottom of the push-pull plate 10 via the connecting rod 9. Two hoppers 3, a small on / off valve 4, and a discharge head 5 are fixed at the top of the reaction tank 1. A connecting frame 6, a transfer cylinder 7, a piston 8, a connecting rod 9, a push-pull plate 10, an inlet pipe 11, and a discharge head 12 are also fixed at the top of the reaction tank 1. In use, solid raw materials can be placed into the hoppers 3. With the small on / off valve 4 closed, the scale bar 24 is used to accurately determine the material. Then, the small on / off valve 4 is opened, and the material in the hoppers 3 is discharged downward into the reaction tank 1 through the discharge head 5. Liquid raw materials are inserted into the source through the inlet pipe 11. When the piston 8 is at its lowest position, the push-pull plate 10 is pulled upward, and the connecting rod 9 moves the piston 8 upward, creating negative pressure inside the transfer cylinder 7. This allows a certain amount of liquid raw materials to be drawn in through the inlet pipe 11. The push-pull plate 10 is then pressed, and the piston 8 pushes the material in the transfer cylinder 7 out through the discharge head 12, where it is mixed and reacted in the reaction tank 1.

[0026] It also includes a handle 13, with the outer side of the top of the transfer cylinder 7 connected to the inner side of the handle 13; when the push-pull plate 10 is pushed or pulled, the handle 13 can help fix the transfer cylinder 7, thus facilitating operation.

[0027] It also includes a one-way valve 14. A set of one-way valves 14 is respectively installed on the feed pipe 11 and the discharge head 2 12. The one-way valve 14 can allow one-way flow between the feed pipe 11 and the discharge head 2 12, avoiding backflow and improving reliability.

[0028] It also includes a collection hopper 15, a discharge head 3 16, and an on / off valve 17. The bottom end of the reaction tank 1 is connected to the top end of the collection hopper 15, the bottom end of the collection hopper 15 is connected to the top end of the discharge head 3 16, and the bottom end of the discharge head 3 16 is connected to the top end of the on / off valve 17. The material in the reaction tank 1 can be collected downward through the collection hopper 15 and discharged through the drive motor 18 after the on / off valve 17 is opened, which improves convenience.

[0029] It also includes a drive motor 18, a reducer 19, a stirring shaft 20, and stirring blades 21. The bottom middle of the hopper 15 is connected to the top of the reducer 19. The output end of the drive motor 18 is connected to the input end of the reducer 19. The output end of the reducer 19 is connected to the bottom end of the stirring shaft 20. The outer side of the stirring shaft 20 is connected to the inner side of multiple sets of stirring blades 21. During the reaction, the drive motor 18 runs and the reducer 19 slows down the speed, causing the stirring shaft 20 to drive multiple sets of stirring blades 21 to move, stirring the mixture, accelerating the reaction rate, and improving practicality.

[0030] It also includes a support 22 and a base 23. The top rear side of the base 23 is connected to the bottom of the support 22, and the top front side of the support 22 is connected to the rear side of the reaction tank 1. The base 23 is in contact with the ground, and the support 22 can connect the reaction tank 1 to a high position for easy material discharge and collection.

[0031] In summary, in the use of a chemical analysis reaction apparatus, the hopper 3, small on / off valve 4, and discharge head 5 are fixed at the top of the reaction vessel 1 via connecting frame 2. The central rotating cylinder 7, piston 8, connecting rod 9, push-pull plate 10, feed pipe 11, and discharge head 12 are also fixed at the top of the reaction vessel 1 via connecting frame 2 6. During use, solid raw materials can be placed into the hopper 3. With the small on / off valve 4 closed, the scale bar 24 is used for accurate judgment. Then, the small on / off valve 4 is opened, and the material in the hopper 3 is discharged downward into the reaction vessel 1 through discharge head 5. Liquid raw materials are inserted into the source through the input end of feed pipe 11. When the piston 8 is at its lowest position, the central rotating cylinder 7 is fixed with the assistance of the handle 13. Pulling the push-pull plate 10 upward causes the piston 8 to move upward via the connecting rod 9. The process creates negative pressure inside the transfer cylinder 7, allowing a quantitative amount of liquid raw material to be drawn in through the feed pipe 11. Then, the push-pull plate 10 is pressed, and the piston 8 forces the material out of the transfer cylinder 7 through the discharge head 12. A one-way valve 14 allows for unidirectional flow between the feed pipe 11 and the discharge head 12, preventing backflow. The material is then mixed and reacted in the reaction tank 1. During the reaction, the drive motor 18 operates, and the speed reducer 19 slows the reaction, causing the stirring shaft 20 to drive multiple sets of stirring blades 21 to agitate the mixture and accelerate the reaction rate. After the reaction is complete, the material is collected downwards through the collection hopper 15 and discharged through the drive motor 18 after the on / off valve 17 is opened. The material is then placed on the ground by the base 23 and connected to the reaction tank 1 by the bracket 22, placing it in a high position for easy collection.

[0032] The small on / off valve 4, check valve 14, on / off valve 17, drive motor 18 and reducer 19 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not elaborate further on them here.
