Description

Technical Field

[0001] This utility model belongs to the field of dissolution instruments, specifically relating to an accelerated dissolution instrument for chemical analysis. Background Technology

[0002] In chemical analysis, sample dissolution efficiency directly affects analytical accuracy and experimental cycle. For samples in different states (solid, liquid, viscous) and with different solubilities (sparingly soluble, slightly soluble), specialized instruments for accelerating dissolution are required. The core principles of these instruments revolve around increasing the rate of molecular motion (heating), increasing the solid-liquid contact area (stirring / pulverizing), and enhancing mass transfer efficiency (ultrasounding / pressurization).

[0003] In existing technologies, traditional dissolution instruments often use a single heating source, which easily leads to a situation where the temperature is high in the center of the beaker and low at the edges. Furthermore, some samples may deteriorate due to excessively high local temperatures, while others dissolve slowly due to insufficient local temperatures. Additionally, traditional magnetic stirring often uses a single stir bar, which only rotates the solution in the center of the beaker, resulting in slow flow of the solution at the edges. This can lead to situations where the solution in the center has dissolved while clumping remains at the edges, prolonging the dissolution time and causing uneven solution concentration, which affects the accuracy of subsequent analyses. Therefore, this invention proposes an accelerated dissolution instrument for chemical analysis to solve the problems existing in the prior art. Utility Model Content

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please see Figures 1-6 This utility model provides an embodiment: a chemical analysis accelerated dissolution instrument, including a base 1 and a beaker 2, a partitioned heating structure disposed on the base 1 and a bidirectional stirring terminal structure disposed in the beaker 2, a storage groove 9 is provided at the upper end of the base 1, a second groove 7 and a third groove 8 are provided on the lower inner wall of the storage groove 9, a first groove 6 is provided through the center of the lower end of the storage groove 9, and the beaker 2 is disposed on the partitioned heating structure.

[0017] The partitioned structure of the central heating ring 12 and the edge heating ring 13 allows for individual or coordinated heating based on sample characteristics. Combined with real-time temperature control by the infrared temperature sensor 21, uneven sample heating can be avoided. The central stirring terminal 5 and the edge stirring terminal 18 are connected in a cross shape, and the synchronous rotation of the center and edge can also drive the flow of the solution in the entire beaker 2, improving the stirring effect of the sample.

[0018] Please see Figures 3-5 In this embodiment, the partitioned heating structure includes a central heating ring 12 installed in the second tank 7, an edge heating ring 13 installed in the third tank 8, two sets of infrared temperature sensors 21 symmetrically mounted at the upper edge of the base 1 via sensor brackets 4, and a glass plate 10 installed in the storage slot 9. The central heating ring 12 and the edge heating ring 13 are independently installed in the second tank 7 and the third tank 8, and their power can be adjusted separately to meet the differentiated needs of high temperature in the central area to accelerate dissolution and low temperature in the edge area to promote convection. The central heating ring 12 is located at the center of the inner wall of the edge heating ring 13, and the glass plate 10 is located at the upper end of the second tank 7 and the third tank 8. The upper end of the glass plate 10 has an outer ring line 14 and an inner ring line 15. The glass plate 10 covers the upper end of the two tanks and can uniformly support the container, avoiding temperature fluctuations caused by the container directly contacting the heating ring. At the same time, the glass material has strong chemical stability and is resistant to acid and alkali corrosion, making it suitable for chemical analysis scenarios.

[0019] Please see Figure 4In this embodiment, the bidirectional stirring terminal structure includes a central stirring terminal 5 and an edge stirring terminal 18. The central stirring terminal 5 and the edge stirring terminal 18 are connected to each other in a cross shape to form a magnetic stirrer terminal. The cross-shaped connection of the central and edge stirring terminals 18 can simultaneously act on the central and edge regions of the solution, avoiding the stirring blind zone of a traditional single stirrer. The upper and lower edges of the central stirring terminal 5 and the edge stirring terminal 18 are both fixed with protrusions 17. The inner wall of the central stirring terminal 5 and the edge stirring terminal 18 is provided with a hollow groove 20. The protrusions 17 on the edge of the terminal can enhance local turbulence during rotation, breaking the laminar flow state of the solution, and the mixing effect is more significant, especially for high viscosity solutions.

[0020] Please see Figures 3-5 In this embodiment, the outer wall of beaker 2 is provided with graduation lines, and a handle 16 is fixedly attached to the edge of the outer wall of beaker 2. A filter groove 19 is provided through the spout on the left side of the outer wall of beaker 2. The filter groove 19 on the spout can directly filter undissolved impurities when pouring the solution, eliminating the need for a separate transfer to a funnel for filtration, reducing sample loss and operation time, and improving analysis efficiency. A CNC console 3 is installed on the right end of the base 1. A magnetic stirrer base 11 is installed in the first tank 6. The CNC console 3 can centrally control parameters such as the heating power and stirring speed of the zones, and display the temperature data monitored by the infrared sensor.

[0021] The infrared temperature sensor can be of the HG04-HBIR-1816 series, IRTSM series, or IRTE series, such as... Figure 6 The workflow diagram shown below illustrates the specific control method as follows: When using, first add the chemical sample to be dissolved and the solvent to the graduated beaker 2 in proportion. Then, place the beaker 2 stably in the storage slot 9 of the base 1 using the handle 16 on the outer wall of the beaker 2, with the bottom of the beaker 2 in contact with the glass plate 10 in the storage slot 9. At the same time, place the bidirectional stirring terminal structure composed of the center stirring terminal 5 and the edge stirring terminal 18 into the beaker 2, ensuring that the terminals are completely immersed in the solution. Next, using the CNC stage 3 on the right side of the base 1, according to the dissolution requirements of the chemical sample, such as the set parameters of temperature and stirring rate, and as needed, the center heating ring 12 can work alone, the edge heating ring 13 can work alone or the two rings can work together to adapt to the heating requirements of different samples. Then, the magnetic stirrer base 11 in the first tank 6 is activated, and the bidirectional stirring terminal structure in the beaker 2 is rotated by magnetic force. Meanwhile, two sets of infrared temperature sensors 21 monitor the temperature of the solution in beaker 2 in real time and feed the data back to the CNC stage 3: if the temperature is lower than the set value, the CNC stage 3 automatically increases the power of the corresponding heating ring center and edge; if the temperature is too high, the power is reduced to ensure the stability of the dissolution temperature. At the same time, the cross-shaped structure of the bidirectional stirring terminal drives the center and edge of the solution to rotate synchronously, accelerating the mixing of the sample and solvent. After the sample has completely dissolved, turn off the heating and stirring functions, filter the trace amounts of undissolved impurities in the solution through the filter tank 19 on the left side of beaker 2, and then transfer the solution to beaker 2 through the handle 16 to complete the subsequent chemical analysis operation.

[0022] Through the above steps, the partitioned structure of the central heating ring 12 and the edge heating ring 13 allows for individual or coordinated heating based on sample characteristics. Combined with real-time temperature control by the infrared temperature sensor 21, uneven sample heating can be avoided. Furthermore, the cross-shaped connection between the central stirring terminal 5 and the edge stirring terminal 18, along with their synchronous rotation, can drive the flow of the solution in the entire beaker 2, improving the stirring effect of the sample. This solves the problem of uneven heating and stirring effects in existing dissolution instruments when assisting in the dissolution of different samples.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
