Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sample detection equipment, in particular to an oscillating device for improving sample detection effect. Background Art
[0002] In the process of production and experiment, liquid sample testing is often required. However, during the sampling, transportation and pouring process, gas is often mixed into the sample to be tested to form bubbles. The bubbles will cause inaccurate sampling volume, thus affecting the detection effect. At the same time, the bubbles will also affect the sensitivity of chromatographic analysis. Therefore, the sample to be tested needs to be defoamed to improve the detection effect. Some liquid samples need to be mutually dissolved or stratified before testing. An oscillator is needed to shorten this process. At the same time, the oscillation also has a certain effect on eliminating smaller and easily broken bubbles in the liquid sample. However, the defoaming method that relies solely on the oscillation equipment is single and the effect is poor. It cannot completely eliminate the bubbles. Therefore, a oscillation equipment with a simple structure and good defoaming effect is needed. Utility Model Content
[0003] In view of the above technical problems, the utility model provides a device for defoaming through vibration and negative pressure environment to improve the sample detection effect.
[0004] In order to solve the above technical problems, the utility model discloses an oscillation device for improving sample detection effect, including an oscillator and a sample box. The sample box is embedded in an oscillation disk above the oscillator. A sampling port and a vacuum tube are fixedly connected to the top of the sample box. The vacuum tube is connected to a first hose through a quick connector. The other end of the first hose is fixedly connected to a vacuum pump.
[0005] Furthermore, the other end of the first hose is connected to the buffer bottle and extends inwardly, the buffer bottle is connected to the vacuum pump via a second hose, and the connection between the first hose, the second hose and the buffer bottle is sealed.
[0006] Furthermore, a portion of the first hose extending into the buffer bottle is longer than a portion of the second hose extending into the buffer bottle.
[0007] Furthermore, the bottom of the oscillating plate is provided with a heating device.
[0008] Furthermore, a check valve is connected to the vacuum tube.
[0009] Furthermore, a pressure relief valve is connected to the top of the sample box.
[0010] Furthermore, a vacuum gauge is connected to the top of the sample box.
[0011] Furthermore, a buffer strip is provided between the sample box and the oscillation plate.
[0012] Compared with the prior art, the utility model has the following advantages:
[0013] 1. The utility model processes the sample to be tested by using vibration and vacuuming. The structure is simple and practical, the efficiency of removing bubbles is high, the influence on the sample detection effect can be reduced, and the detection accuracy of the sample is improved.
[0014] 2. The utility model makes the device safer to use by arranging a buffer bottle, a check valve, a pressure relief valve and a vacuum gauge. The buffer strip also avoids damage to the sample box during the oscillation process. At the same time, a heating device is added to the bottom of the oscillation plate, which can accelerate the floating of bubbles and improve the defoaming efficiency.

[0017] The utility model will be further described below in conjunction with the accompanying drawings.
[0018] like Figure 1 An oscillation device for improving sample detection effect is shown, including an oscillator 1 and a sample box 2. The sample box 2 is embedded in an oscillation disk 101 above the oscillator 1. A sampling port 3 and a vacuum tube 5 are fixedly connected to the top of the sample box 2. The vacuum tube 5 is connected to a first hose 9 through a quick connector 6. The other end of the first hose 9 is fixedly connected to a vacuum pump 11.
[0019] It should be noted that the oscillator 1 used in this embodiment is an ultrasonic frequency modulation oscillator, which is an existing device and its specific structure will not be described in detail.
[0020] In order to prevent the sample to be tested from entering the vacuum pump 11 and causing damage to the vacuum pump 11 during the vacuuming process, the other end of the first hose 9 is connected to the buffer bottle 10 and extended inward, and the buffer bottle 10 is connected to the vacuum pump 11 through the second hose 12. The connection between the first hose 9, the second hose 12 and the buffer bottle 10 is sealed.
[0021] In order to further prevent the sample to be tested from entering the vacuum pump 11 , the portion of the first hose 9 extending into the buffer bottle 10 is longer than the portion of the second hose 12 extending into the buffer bottle 10 .
[0022] In order to accelerate the floating speed of bubbles and improve the defoaming efficiency, a heating device is added to the bottom of the oscillating plate 101 to improve the fluidity of the liquid sample, thereby increasing the floating speed of bubbles. In this embodiment, heating wire heating is used.
[0023] In order to prevent foreign matter from entering the sample to be tested and to prevent gas from flowing back after the vacuum pump 11 is turned off, a check valve 4 is connected to the vacuum tube 5 .
[0024] In order to facilitate pressure relief after defoaming is completed and to facilitate opening the sampling port 3 for sampling, a pressure relief valve 8 is connected to the top of the sample box 2 .
[0025] In order to accurately control the vacuum degree, a vacuum gauge 7 is connected to the top of the sample box 2 .
[0026] In order to prevent the sample box 2 from breaking due to vibration and to increase the service life of the sample box 2 , a buffer strip is provided between the sample box 2 and the vibration plate 101 to fill the gap between the sample box 2 and the vibration plate 101 .
[0027] The working process of this embodiment is as follows:
[0028] Add the sample to be tested into the sample box 2, connect the first hose 9 to the vacuum tube 5 through the quick connector 6, then turn on the oscillator 1 and start constant temperature heating. After three to five minutes, stop the oscillation, turn on the vacuum pump 11, and wait for the remaining bubbles to float up. During this period, observe the vacuum gauge 7 to prevent the vacuum from being too high, maintain -80KPa to -90KPa. After maintaining for 10 minutes, turn off the vacuum pump 11, open the pressure relief valve 8, balance the pressure inside and outside the sample box 2, and then open the sampling port 3 to take samples for the next step of testing.
