Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a detection device for ethanol derivatives. Background Technique

[0002] Ethanol derivatives refer to more complex products derived from the substitution of hydrogen atoms or atomic groups in ethanol by other atoms or atomic groups. Acetaldehyde, also known as acetic aldehyde, is one of them. It is a colorless and transparent liquid compound, soluble in water, ethanol, ether and other organic solvents. It can be used as a reducing agent and a bactericide. Industrially, it can be used to produce synthetic rubber, essence, etc. It has a wide range of uses and is toxic. Therefore, in life and production, we often test whether something contains acetaldehyde.

[0003] The existing acetaldehyde detection usually involves manual operation to conduct a chemical reaction test on the sample solution to detect whether the sample solution contains acetaldehyde. For example, first add 2 drops of 10% sodium hydroxide solution to a test tube, then add 5 - 8 drops of 2% copper sulfate solution, then shake the solution to mix it thoroughly, then add the sample solution to the test tube, continue to shake the solution to mix it repeatedly, and then heat the test tube. It is judged whether the sample contains acetaldehyde by whether the solution changes color and whether there is a precipitate. Generally, the tester shakes the test tube by swinging the wrist to accelerate the mixing of the solution. During the process, it is impossible to prepare for the next step, and the long-term swinging will damage the tester's wrist, affecting the test efficiency and the tester's physical health. Therefore, we propose a detection device for ethanol derivatives to solve the above-mentioned problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages in the prior art that the solution is accelerated and mixed by swinging the wrist to shake the test tube, and it is impossible to prepare for the next step during the process, and the long-term swinging will damage the tester's wrist, and to propose a detection device for ethanol derivatives.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A detection device for ethanol derivatives, including a base. An alcohol lamp is arranged on the top of the base, a reagent bottle is arranged on the top of the base, a support frame is fixedly connected to the top of the base, a test tube rack is fixedly connected to the top of the base. The same baffle is fixedly connected to both sides inside the test tube rack, and a plurality of holes for placing test tubes are opened at the top of the test tube rack. The detection device for ethanol derivatives further includes:

[0007] Two oscillation components, both of which are arranged at the bottom of the support frame. The oscillation components are used to oscillate the test tube to accelerate the full mixing of the solution;

[0008] Two test tube clamping assemblies are respectively arranged on the corresponding oscillation assemblies, and the test tube clamping assemblies are used to clamp test tubes.

[0009] In a possible design, an M-shaped chute frame is fixedly arranged at the top of the test tube rack. A chute is opened at the top of the M-shaped chute frame. A hollow slider is slidably connected to the inner wall of the chute. A funnel rack is slidably connected to the top of the hollow slider. A funnel is placed on the funnel rack. One side of the hollow slider is threadedly connected with a limit bolt, and one end of the limit bolt abuts against the outside of the funnel rack. The limit bolt is used to fix the funnel rack.

[0010] In a possible design, the oscillation assembly includes a support plate fixedly arranged at the bottom of the support frame. A first fixed column is fixedly connected to one side of the support plate. A U-shaped swing arm is rotatably connected to the first fixed column. A second support arm is rotatably connected to one side of the U-shaped swing arm. A first support arm is rotatably connected to one side of the second support arm. The first support arm is fixedly connected with a drive assembly.

[0011] In a possible design, the drive assembly includes a micro motor arranged on the other side of the support plate. The output end of the micro motor penetrates through the other side of the support plate and is fixedly connected with the first support arm.

[0012] In a possible design, the test tube clamping assembly includes a first clamp block rotatably connected to the corresponding U-shaped swing arm. A second fixing bolt is threadedly connected to the top of the first clamp block. A second clamp block is rotatably connected to the first clamp block. The bottom end of the second fixing bolt abuts against the top of the second clamp block. The second fixing bolt is used to fix the second clamp block.

[0013] In a possible design, a first fixing bolt is threadedly connected to the top of the U-shaped swing arm. One end of the first clamp block is provided with a hexagonal prism. One end of the first fixing bolt abuts against the outside of the hexagonal prism. The hexagonal prism is used to facilitate abutting and fixing with the first fixing bolt.

[0014] In a possible design, soft gaskets made of rubber material are arranged on the mutually approaching sides of the first clamp block and the second clamp block. The gaskets are used to play a buffering role when clamping the test tube to prevent the test tube from being damaged due to clamping.

[0015] In this application, first, place the test tube into the hole on the test tube rack. Then, by moving the hollow slider on the M-shaped chute rack, the hollow slider can move within the chute on the M-shaped chute rack, so that the funnel on the hollow slider can be moved directly above any test tube. When adding the same reagent to multiple test tubes, the reagent can be quickly and accurately dropped into the test tube through the funnel. When other solutions need to be added, simply replace the funnel, then turn the second fixing bolt on the first clamping block to move the second clamping block away from the first clamping block. Next, take out one of the test tubes that has already had the reagent added and place it into the space between the first clamping block and the second clamping block from top to bottom. Then, rotate the second clamping block to make the first clamping block and the second clamping block closely fit the test tube. Next, slowly turn the second fixing bolt to fix the second clamping block, thereby fixing the test tube between the first clamping block and the second clamping block. Subsequently, start the micro-motor. The rotation of the micro-motor drives the first support arm to rotate, causing the U-shaped swing arm connected to the first support arm to move back and forth left and right, so that the solution in the test tube vibrates and mixes thoroughly. During this process, the tester can place the next test tube to be tested in the same way on another clamping assembly, reducing the operation time. After the mixing is completed, stop the micro-motor to make the U-shaped swing arm stop moving back and forth and the test tube stop vibrating. Then, add the sample solution to be tested to the test tube. Next, start the micro-motor again. During the waiting process, another test tube can be operated on. After the solution is thoroughly mixed, turn the first fixing bolt to loosen the fixation between the first clamping block and the U-shaped swing arm, so that the first clamping block can rotate. According to the inclination angle at which the test tube is to be burned, adjust the angle between the first clamping block and the U-shaped swing arm, and then tighten the first fixing bolt. Then, take out the alcohol lamp and heat the test tube. During this process, the test tube is fixed by the first clamping block and the second clamping block, eliminating the need for manual operation by the tester. During the waiting process, the tester can debug the next sample, increasing the work efficiency and the testing rate. It is judged whether acetaldehyde is contained in the sample solution by whether the solution changes color and whether there are precipitates after heating.

[0018] In this utility model, for the ethanol derivative detection device, by setting an oscillating assembly that automatically swings back and forth left and right, the reagent solution is accelerated in mixing, improving the testing rate. At the same time, it eliminates the need for manual operation by the tester, enabling the tester to prepare the next operation step, and at the same time avoiding damage to the tester's wrist caused by long-term shaking;

[0019] In the present utility model, by providing a movable funnel, the same reagent can be quickly and accurately dropped into the test tube, avoiding the reagent solution dropping outside the test tube due to the small opening of the test tube. At the same time, an oscillation assembly that automatically swings left and right is provided, avoiding damage to the tester's wrist caused by long-term shaking, accelerating the mixing of the reagent solution, and liberating both hands so that the tester can prepare for the next operation step, improving the testing rate.
