Description

Technical Field

[0001] The utility model belongs to the technical field of acid-removing liquid level monitoring, and more specifically relates to an acid-removing device capable of monitoring the liquid level. Background Art

[0002] When analyzing heavy metals in the medium, the sample is generally pre-treated, including digestion, acid removal and volume determination, before analysis can be performed on the machine. Acid removal can protect the analytical instrument while reducing the acid concentration of the sample solution. Generally, the acid removal is required to leave 1-5 mL of solution.

[0003] In the existing scheme, the digestion tank after microwave digestion is generally placed in an acid remover, and then the temperature is adjusted to remove the acid. The experimenter repeatedly observes the volume of the remaining digestion solution to determine the acid removal time. If there is a lot of remaining solution, the acid removal will be incomplete. If there is little remaining solution or it is evaporated to dryness, it will cause the loss of the element to be measured, causing deviations in the experimental results.

[0004] Since both the acid remover and the digestion tank are opaque structures, in order to ensure that the final remaining solution meets the requirements, the experimenter needs to repeatedly take out the digestion tank for observation, which will cause multiple interruptions in the heating process of the digestion tank and prolong the acid removal time. In addition, manual observation cannot accurately determine the liquid level, and there is a risk of scalding or acid burns during the operation, which affects the safety of the experiment.

The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0026] Please also read Figures 1 to 3 , the acid-removing device capable of monitoring liquid level provided by the utility model is now described. The acid-removing device capable of monitoring liquid level comprises an operation box 1, an acid-removing device 2, a laser transceiver 3 and a reflector 4. The acid-removing device 2 is arranged in the operation box 1, a digestion tank 21 is arranged in the acid-removing device 2, the laser transceiver 3 is arranged outside the operation box 1, a perspective window 11 corresponding to the level of the laser transceiver 3 is embedded on the side of the operation box 1, and the reflector 4 is connected to the inner side of the operation box 1 and tilted from bottom to top toward a side close to the laser transceiver 3;

[0027] Among them, the laser transceiver 3 is used to emit a first light beam 12, and the first light beam 12 is reflected by the reflector 4 to the digestion liquid 22 in the digestion tank 21; the digestion liquid 22 in the digestion tank 21 is used to reflect the first light beam 12 and form a second light beam 13, and the second light beam 13 can be reflected by the reflector 4 to the laser transceiver 3.

[0028] The acid-removing device capable of monitoring liquid level provided in the present embodiment is compared with the prior art. The acid-removing device capable of monitoring liquid level provided in the present embodiment is arranged in an acid-removing device 2 in an operation box 1, and a transparent window 11 on the side of the operation box 1 is used for a laser transceiver 3 to emit a first light beam 12, and project it onto the surface of a digestion liquid 22 in a digestion tank 21 under the reflection of a reflector 4, and then reflect to generate a second light beam 13. The second light beam 13 is reflected to the laser transceiver 3 through the reflector 4, and then it is determined whether the digestion liquid 22 remains at the position irradiated by the first light beam 12. The determination method is simple and convenient, eliminates the tediousness of manual operation, improves the test efficiency, ensures the safety of the operation process, and improves the accuracy of the test results.

[0029] It should be noted that the bottom of the digestion solution 22 has a small concave arc, and the internal digestion solution 22 needs to be acid-driven to droplets with a diameter of 3mm-6mm. Since the above droplets will eventually form the center position of the digestion tank 21, when installing the laser transceiver 3, the position of the first light beam 12 projected on the inner bottom surface of the digestion tank 21 should correspond to the edge position of the droplet. When the first light beam 12 can form the second light beam 13 under the action of the digestion solution 22, it proves that the coverage area of ​​the digestion solution 22 on the inner bottom surface of the digestion tank 21 is too large, and the acid driving is not completed; when the first light beam 12 is difficult to form the second light beam 13 under the action of the digestion solution 22, it proves that there is no digestion solution 22 at the position where the first light beam 12 is projected on the inner bottom surface of the digestion tank 21. At this time, the digestion solution 22 has completed the acid driving, and the acid driving step needs to be stopped to avoid the loss of the element to be measured due to too little residual solution, so as to ensure the accuracy of the experimental results.

[0030] In one possible implementation, see Figures 1 to 3 The reflector 4 is connected to the inner wall of the operation box 1 through a folding component 5. The folding component 5 includes a mounting seat 51 connected to the inner wall of the operation box 1, a folding rod 52 hinged on the mounting seat 51, and a telescopic driving member 53 connected to the inner wall of the operation box 1 and connected to the folding rod 52. The reflector 4 is connected to the extended end of the folding rod 52. The folding rod 52 can swing vertically under the drive of the telescopic driving member 53 to drive the reflector 4 to be folded at the top of the operation box 1.

[0031] In this embodiment, the reflector 4 is installed in the operating box 1 through the folding component 5. When not in use, the reflector 4 can be stored through the folding component 5 to avoid the upper space of the acid remover 2 to avoid space occupation, making it convenient to perform other operations in the operating box 1.

[0032] Specifically, the folding rod 52 is installed using the mounting seat 51, and the folding rod 52 is driven to swing vertically by the telescopic driving member 53, and then the folding rod 52 is used to drive the reflector to a position away from the digestion tank 21, so that it is stored on the top of the operation box 1, forming a good space avoidance effect.

[0033] For some examples, see Figures 1 to 3 The fixed end of the telescopic driving member 53 is hinged to the inner wall of the operating box 1 and is located below the mounting seat 51 . The telescopic end of the telescopic driving member 53 extends upwardly toward the axial center side of the operating box 1 and is connected to the folding rod 52 .

[0034] In this embodiment, the telescopic driving member 53 has a fixed end and a driving end. The fixed end is hinged to the inner wall of the operating box 1, and the driving end is hinged to the folding rod 52. It can drive the folding rod 52 to swing vertically, and then drive the reflector 4 to change its position, so that the reflector 4 can be switched between the use state and the folded state.

[0035] In one possible implementation, see Figures 1 to 3 The mounting seat 51 is hinged to the end of the folding rod 52 through a first axis 511 , the driving end of the telescopic driving member 53 is connected to the hinge seat 54 , and the hinge seat 54 is rotationally connected to the folding rod 52 through a second axis 541 .

[0036] In this embodiment, the first axis 511 on the mounting seat 51 can realize the vertical swing of the folding rod 52, the hinge seat 54 on the telescopic driving member 53 has a space for the folding rod 52 to pass through, and the second axis 541 on the hinge seat 54 is used to cooperate with the middle part of the folding rod 52 in rotation. When the telescopic driving member 53 is extended outward, the folding rod 52 can be driven to swing vertically upward, so that the folding rod 52 and the top of the reflector box operating box 1 are synchronized and retracted, thereby realizing effective avoidance of the upper space of the digestion tank 21.

[0037] In one possible implementation, see Figures 1 to 3 The reflector 4 is hinged to the outer end of the folding rod 52 through a universal damping ball head 41, and the universal damping ball head 41 is connected to the side of the reflector 4 away from the laser transceiver 3 and is located in the middle of the reflector 4. The reflector 4 is hinged to the outer end of the folding rod 52 through the universal damping ball head 41, so that the angle of the reflector 4 can be adjusted by using the universal damping ball head 41, so that the first light beam 12 can be accurately radiated to the corresponding position of the inner bottom wall of the digestion tank 21, meeting the liquid level monitoring requirements of the digestion solution 22, so as to ensure the accuracy of the acid removal operation.

[0038] In one possible implementation, see Figures 1 to 3 There are a plurality of digestion tanks 21 in the operation box 1 , and a plurality of laser transceivers 3 are also provided. The plurality of laser transceivers 3 are arranged in a one-to-one correspondence with the plurality of digestion tanks 21 .

[0039] According to the number of samples of the digestion solution 22 that need to be acid-removed, multiple digestion tanks 21 can be set to simultaneously remove the acid from multiple samples, and the same number of laser transceivers 3 are set accordingly, so that the laser transceivers 3 correspond to the digestion tanks 21 one by one, and the digestion solutions 22 in different digestion tanks 21 are monitored respectively.

[0040] Specifically, each laser transmitter is independently provided with a switch, so as to facilitate the opening and closing of the laser transceiver 3 according to the actual acid-removing condition, which helps to improve the acid-removing efficiency.

[0041] In one possible implementation, see Figures 1 to 3 The acid-removing device capable of monitoring the liquid level also includes a controller 6, which is electrically connected to the laser transceiver 3 and is used to send a transmission signal to the laser transceiver 3 and receive a laser signal from the laser transceiver 3. The controller 6 is electrically connected to a buzzer alarm 7, and the controller 6 is used to send a buzzer signal to the buzzer alarm 7.

[0042] In this embodiment, during the acid-removing process, the laser transceiver 3 can continuously receive the second light beam 13 and send a laser signal to the controller 6. When the laser transceiver 3 cannot receive the second light beam 13, it stops sending the laser signal to the controller 6. At this time, it is difficult for the controller 6 to receive the laser signal from the laser transceiver 3. It can be determined that the acid-removing operation has been completed according to the internal preset program. At this time, the controller 6 sends a buzzer signal to the buzzer alarm 7, so that the buzzer alarm 7 emits an alarm sound to remind the operator to perform subsequent operations.

[0043] In one possible implementation, see Figures 1 to 3 A signal amplifier 8 is further provided between the laser transceiver 3 and the controller 6. The signal amplifier 8 is used to receive the laser signal to amplify the laser signal to form an amplified signal, and send the amplified signal to the controller 6. The signal amplifier 8 can achieve the effect of amplifying the signal, so as to improve the accuracy of the laser transceiver 3 in receiving the second light beam 13 and improve the accuracy of liquid level monitoring.

[0044] For some examples, see Figures 1 to 3 The controller 6 is also electrically connected to a warning light 9, and the controller 6 is used to send a warning signal to the warning light 9. The setting of the warning light 9 is used to send a warning signal, and the warning signal is a light signal. While the buzzer prompt is performed, the operator can conveniently observe the corresponding warning light 9 that sends the warning signal, and then judge the completion of the acid removal of the digestion solution 22 in the corresponding digestion tank 21, thereby improving the convenience of operation.

[0045] In one possible implementation, see Figures 1 to 3 The lower part of the operating box 1 is connected to an air duct 14 for exhausting air to the outside. The operating box 1 is provided with a blower 15 arranged toward one side of the air duct 14. The blower 15 is arranged higher than the upper end surface of the digestion tank 21 and is used to guide the gas in the digestion tank 21 to flow into the air duct 14. The surface of the reflector 4 is provided with an anti-fog film.

[0046] In this embodiment, in order to prevent the steam from affecting the reflection of the upper reflector 4 and the transparency of the perspective window 11 during the acid removal process, an air duct 14 capable of drawing air outward under negative pressure is provided on the side of the operating box 1, and a blower 15 is provided to deliver the steam into the air duct 14 to ensure the effective extraction of the steam. At the same time, an anti-fog film is provided to prevent the reflector 4 and the perspective window 11 from generating water mist, thereby improving the accuracy of monitoring.

[0047] The acid-removing device capable of monitoring the liquid level is provided with the acid-removing device 2 in the operating box 1, and the transparent window 11 on the side of the operating box 1 is used for the laser transceiver 3 to emit a first light beam 12, and project it onto the surface of the digestion liquid 22 in the digestion tank 21 under the reflection of the reflector 4, and then reflect to generate a second light beam 13, and the second light beam 13 is reflected to the laser transceiver 3 through the reflector 4, and then it is judged whether the digestion liquid 22 remains at the position irradiated by the first light beam 12. The judgment method is simple and convenient, eliminating the tedious manual operation, improving the test efficiency, ensuring the safety of the operation process, and improving the accuracy of the test results.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
