Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for solution preparation, specifically a solution preparation tray for a fume hood with a replaceable ice box. Background Technology

[0002] When performing qualitative and quantitative analysis on complex mixtures with multiple components, the mixture needs to be dissolved in a solvent and placed into sample vials. Depending on the testing requirements, various types of test solutions with different solvents and specific gravities are typically prepared and then placed in trays for subsequent instrument loading and analysis. Existing sample vial trays are mostly simple in structure, only capable of holding a single-sized sample vial. Multiple trays are needed to hold sample vials of different capacities. Furthermore, to prevent the evaporation of the prepared solution from affecting the accuracy of the analysis, it needs to be kept in a relatively low-temperature environment. However, existing trays often lack low-temperature storage capabilities, impacting the quality of subsequent analysis. Utility Model Content

[0003] The purpose of this invention is to provide a solution preparation tray for a fume hood with a replaceable ice box, which can not only hold sample bottles of different capacities, but also provide low-temperature storage through the internal ice box, thus solving the problems in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a solution preparation tray for a fume hood with a replaceable ice box, including a tray body with several square slots. Each square slot has an elastic clamp on its inner peripheral wall. The bottoms of the elastic clamps in the same square slot tend to converge towards each other. A first placement slot is formed in the tray body below the square slots, and a detachable ice box is installed in the first placement slot. The ice box provides a low-temperature environment for the top square slots. A second placement slot is formed in the tray body between the first placement slot and the square slots, and a hot water exchange bag is installed in the second placement slot. A first grid mesh is provided between the hot water exchange bag and the ice box. The front end of the first placement slot is open, and a protrusion is provided at the bottom of the front end of the first placement slot. The ice box can be tilted and placed into the first placement slot above the protrusion. After the ice box is fully inserted into the first placement slot, the protrusion provides a horizontal limit to the front end of the ice box. The ice box has a pull ring at the front end, a connecting strap installed on the pull ring, and a buckle at the end of the connecting strap. A groove for engaging the buckle is located on the end face of the tray body below the first placement slot. A second grid is located at the bottom of the first placement slot. Two first inclined surfaces, tilted towards the center, are located within the tray body below the second grid. A water collection trough is located between the bottoms of the two first inclined surfaces. A second inclined surface is located at the bottom of the water collection trough. A plug for engaging the water collection trough is installed on the tray body at the bottom position of the second inclined surface.

[0005] The positive effects of this utility model are as follows: The solution preparation tray for a fume hood with a replaceable ice box described in this utility model has elastic clamps in each grid slot that can automatically adjust the clamping force according to the size of the sample bottle, ensuring that the sample bottle is placed stably. This enables flexible filling of sample bottles of different capacities and types, improving the applicability of the solution preparation tray. At the same time, the internal ice box provides a continuous low-temperature environment for the solution in the tray, effectively slowing down the evaporation rate of the solution, ensuring the concentration and stability of the solution, thereby improving the accuracy and reliability of subsequent detection.

[0012] The present invention describes a solution dispensing tray for a fume hood with a replaceable ice box, such as... Figure 1-3 As shown, the device includes a tray body 1, on the upper surface of which are evenly distributed several square slots 2, each slot 2 for placing sample vials. The solution preparation tray is typically placed in a fume hood, a commonly used laboratory device with exhaust functions to ensure that harmful gases generated during solution preparation or experimental operations do not diffuse to the outside, thus protecting the operator's safety.

[0013] In order to accommodate sample bottles of different capacities, each grid slot 2 is provided with an elastic clamp 3 on its inner peripheral wall. The bottoms of the elastic clamps 3 in the same grid slot 2 tend to converge and move closer to each other. Sample bottles of different diameters can be inserted downwards between the elastic clamps 3, and the sample bottles are clamped and fixed by the elastic force of each elastic clamp 3. The elastic clamps 3 can automatically adjust their clamping force according to the size of the sample bottle to ensure the stable clamping and placement of the sample bottle, thereby improving the applicability of the solution preparation tray.

[0014] To achieve the low-temperature storage function of the solution preparation tray, a first placement slot 4 is provided inside the tray body 1 located on the lower side of the grid slot 2. A detachable ice box 18 is installed in the first placement slot 4, providing a low-temperature environment for the top grid slots 2. The ice box 18 is a sealed box filled with a refrigerant, such as ice or a gel-like cooling material. It can be kept at a relatively low temperature by external refrigeration equipment before being placed into the first placement slot 4. The ice box 18 is detachable; due to the long solution preparation process, users can replace it with a new ice box 18 as needed to maintain the low-temperature state within the tray.

[0015] Furthermore, to avoid direct contact between the ice box 18 and the sample vial, which could cause the ultra-low temperature of the ice box 18 to affect the strength of the sample vial or disrupt the stability of the solution inside, leading to inaccurate subsequent detection, such as... Figure 4 As shown, a second placement slot 5 is provided in the tray body 1 between the first placement slot 4 and the grid slot 2. A heat exchange bag 6 is installed in the second placement slot 5. The heat exchange bag 6 serves as the heat exchange medium between the ice box 18 and the sample bottle. While achieving low-temperature transmission, it can also prevent direct contact between the ice box 18 and the sample bottle, thereby ensuring the stability of the solution in the sample bottle and ensuring the accuracy of subsequent test results.

[0016] The hot water exchange bag 6 has an opening for water supply and drainage and a sealing plug on one side to facilitate the replacement of the internal hot water exchange medium. A first grid mesh 7 is provided between the hot water exchange bag 6 and the ice box 18. The first grid mesh 7 not only increases the contact area between the hot water exchange bag 6 and the ice box 18 and improves the heat exchange efficiency, but also provides effective support for the hot water exchange bag 6.

[0017] Furthermore, in order to achieve a stable installation of the ice box 18 in the first placement slot 4, the front end of the first placement slot 4 is open, and a boss 8 is provided at the bottom position of the front end of the first placement slot 4. The ice box 18 can be tilted and placed into the first placement slot 4 above the boss 8. After the ice box 18 is completely inserted into the first placement slot 4, the front end of the ice box 18 can rotate and fall into the first placement slot 4. The boss 8 can form a horizontal limit on the front end of the ice box 18 to prevent the ice box 18 from falling out of the first placement slot 4.

[0018] To facilitate pulling the ice box 18 out of the first placement slot 4 when replacing it, the front end of the ice box 18 is provided with a pull ring 9, a connecting strap 10 is installed on the pull ring 9, and a buckle 11 is provided at the end of the connecting strap 10. A slot 12 that mates with the buckle 11 is provided on the end face of the lower tray body 1 of the first placement slot 4. When the ice box 18 is in normal use in the first placement slot 4, the buckle 11 is inserted into the slot 12, tauting the connecting strap 10. Pulling the front end of the ice box 18 presses it against the boss 8, and the ice box 18 is in a relatively stable state within the first placement slot 4. When it is necessary to replace the ice box 18, simply remove the buckle 11 from the slot 12, pull the connecting strap 10 diagonally upwards, and the ice box 18 can be pulled out of the first placement slot 4 together.

[0019] Furthermore, to facilitate the collection of condensate inside the tray, such as Figure 5 As shown, a second grid 13 is provided at the bottom of the first placement slot 4. The second grid 13 supports the ice box 18 while allowing condensate water inside the first placement slot 4 to flow downwards. Two first inclined surfaces 14, tilted towards the center, are provided inside the tray body 1 below the second grid 13. A water collection trough 15 is provided between the bottoms of the two first inclined surfaces 14. The first inclined surfaces 14 guide the condensate water to flow into the water collection trough 15 and collect the condensate water within it.

[0020] The bottom of the water collection tank 15 is provided with a second inclined surface 16. Corresponding to the bottom position of the second inclined surface 16, a plug 17 that matches the water collection tank 15 is installed on the tray body 1. When it is necessary to remove the internal condensate, the plug 17 is pulled out, and the condensate in the water collection tank 15 can flow out along the second inclined surface 16 under its own weight.

[0021] The solution preparation tray with replaceable ice packs described in this utility model, through the design of a multifunctional grid groove 2, replaceable ice packs 18, adjustable hot water exchange bladder 6, and convenient drainage system, not only improves the flexibility and efficiency of solution preparation, but also ensures the stability and safety of the solution during storage, providing strong support for scientific research experiments and testing work.
