While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0036] like Figures 1-5 As shown, this utility model provides a digestion and acid removal device, which includes:

[0037] Main body 1, the interior of main body 1 has multiple first cavities 2 with upward openings;

[0038] Multiple rods 3, one rod 3 is vertically arranged inside each first cavity 2, and heating elements are distributed on the inner side of the first cavity 2 and on the rod 3;

[0039] Test tube 4 has a second cavity 5 with its opening facing downwards. Test tube 4 is used to be placed inside the first cavity 2, and rod 3 is used to be inserted into the second cavity 5.

[0040] Specifically, to address the problem of uneven heating and low acid removal efficiency in existing electric hot plate acid removal instruments when heating test tubes, this invention provides a digestion and acid removal device. Each first cavity 2 on the main body 1 of this device has a vertically installed rod 3 inside. The test tube 4 has a downward-facing second cavity 5 inside. Heating elements are distributed on the inner side of the first cavity 2 and on the rod 3. During the digestion and acid removal process, the test tube 4 can be placed inside the first cavity 2, and the rod 3 can be inserted into the second cavity 5. At this time, the heating element on the inner side of the first cavity 2 can heat the outer side of the test tube 4, and the heating element on the rod 3 can heat the inner side of the test tube 4. Simultaneous heating of the inner and outer sides achieves uniform heating of the test tube 4. This device is suitable for sample pretreatment in environmental protection, chemical, food, and pharmaceutical industries, enabling simultaneous digestion and acid removal, shortening the pretreatment time for element detection. Generally, 2 ml of acid solution can be evaporated to the size of a soybean in 1 hour, improving detection efficiency.

[0041] Preferably, the rod body 3 has an upward-facing third cavity inside. The digestion and acid removal device also includes multiple telescopic drive members 9, each of which is disposed in a third cavity. The output end of the telescopic drive member 9 passes through the opening and is used to abut against the top of the second cavity 5. The test tube 4 can move along the axial direction of the first cavity 2 when driven by the telescopic drive member 9.

[0042] Specifically, the telescopic drive 9 can be an electric, hydraulic, or pneumatic telescopic drive. When the output end of the telescopic drive 9 is raised, it can press against the top of the second cavity 5 and push the test tube 4 out of the first cavity 2, making it easier for the operator to understand the digestion and acid removal process, avoiding errors caused by manually operating the test tube 4, and improving safety.

[0043] Preferably, the digestion and acid removal device further includes:

[0044] Robotic arm 6, one end of which is connected to the main body 1;

[0045] Camera 7 is connected to the other end of robotic arm 6;

[0046] The remote digital display is electrically connected to the camera 7 and the telescopic drive 9.

[0047] Specifically, the remote digital display is equivalent to a visual controller. It can control the raising and lowering of each telescopic drive component 9. The addition of a camera 7, working in conjunction with the telescopic drive components 9, allows for real-time monitoring of the digestion and acid removal process inside each test tube 4. This facilitates operators' understanding of the digestion and acid removal status. Visualizing the reaction process through electronic information technology is beneficial to operator health. The program controlling the raising and lowering of the telescopic drive components 9 is existing technology.

[0048] Preferably, the digestion and acid removal device further includes a controller 8, a temperature controller, an air acidity detection sensor, and an alarm. The controller 8, temperature controller, air acidity detection sensor, and alarm are all mounted on the main body 1. The controller 8 is electrically connected to the air acidity detection sensor, the alarm, the temperature controller, and the heating element.

[0049] The controller 8 can send an alarm signal to the alarm based on the data detected by the air acidity detection sensor;

[0050] The controller 8 can send temperature control signals to the heating element according to the instructions set by the temperature controller.

[0051] Specifically, because a large amount of acid vapor is generated during the digestion process, which can easily irritate the respiratory tract and lungs of operators, an air acidity detection sensor has been added. When the acidity reaches a certain range, an alarm will be triggered, and operators can take relevant actions based on the alarm and open windows for ventilation in time, without having to wait next to the equipment. This reduces the inhalation of acid vapor and also avoids the corrosive effect of excessive acid vapor on instruments and laboratories. The alarm control program is existing technology.

[0052] The thermostat can achieve timed constant temperature heating from 0 to 200 degrees Celsius. When the temperature reaches the set heating time, it can provide an alarm prompt. The constant temperature setting program is existing technology.

[0053] Preferably, the digestion and acid removal device further includes:

[0054] Multiple gravity sensors 10 are connected to the telescopic ends of multiple telescopic drive components 9 respectively;

[0055] Multiple flashing indicator lights 11 are located on the top of the main body 1 and are respectively located near multiple first cavities 2. Adjacent gravity sensors 10 and flashing indicator lights 11 are electrically connected through a remote digital display. The remote digital display can send flashing indication signals to the adjacent flashing indicator lights 11 based on the data detected by the gravity sensors 10.

[0056] Specifically, since each sample is different, the digestion and acid removal process is also different. Therefore, a gravity sensor 10 is installed at the telescopic end of each telescopic drive 9. The original acid solution in the test tube 4 is generally about 2-5 ml. The gravity sensor 10 is set so that when the acid solution is 1 ml, the gravity sensor 10 detects 1 gram. The remote digital display can display the detection data of each gravity sensor 10.

[0057] When multiple different samples are digested and acid-removed, when one of them is heated and digested to a transparent or semi-transparent liquid state and the gravity sensor detects 1 gram, the corresponding flash indicator 11 will flash to indicate that it is about time to remove the corresponding test tube 4. At this time, the experimenter should go to the site to observe and wait until it evaporates to the size of a soybean before removing the corresponding test tube 4. The flash control program is existing technology.

[0058] Preferably, the test tube 4 includes a tube body and a cap. The cap is used to be placed at the opening of the tube body. The side of the cap near the tube body has a protruding conical surface, and the diameter of the cap is 33mm.

[0059] Specifically, the protruding conical surface allows droplets to slide into the tube, preventing them from accumulating on one side of the cap.

[0060] Preferably, the diameter of the tube is 29 mm and the height of the tube is 110 mm.

[0061] Preferably, the diameter of the first cavity 2 is 34 mm and the depth of the first cavity 2 is 80 mm.

[0062] Specifically, the existing cavity for placing the tube has a depth of 40mm, which limits the heating area and reduces the acid removal efficiency. The first cavity 2 of this application is designed with a depth of 80mm, which increases the heating area and thus improves the acid removal efficiency.

[0063] Preferably, the bottom of the test tube 4 is provided with a protruding first arc-shaped surface, and the bottom of the first cavity 2 is provided with a recessed first arc-shaped surface. The protruding first arc-shaped surface is used to fit against the recessed first arc-shaped surface.

[0064] Specifically, the protruding first arc surface matches the concave first arc surface, improving the stability of test tube 4 and increasing the heating area.

[0065] Preferably, the output end of the telescopic drive member 9 is provided with a protruding second arc-shaped surface, and the top of the second cavity 5 is provided with a recessed second arc-shaped surface. The protruding second arc-shaped surface is used to fit against the recessed second arc-shaped surface.

[0066] Specifically, the protruding second arc surface matches the concave second arc surface, increasing the contact area and thus improving the stability of test tube 4 during lifting and lowering.

[0067] Preferably, test tube 4 is provided with a 0-50ml graduation line.

[0068] In summary, when implementing the digestion and acid removal device of this utility model, the test tube 4 can be placed in the first chamber 2 and the rod 3 can be inserted into the second chamber 5. At this time, the heating element on the inner side of the first chamber 2 can heat the outer side of the test tube 4, and the heating element on the rod 3 can heat the inner side of the test tube 4. When the inner and outer sides are heated simultaneously, the test tube 4 can be heated evenly. It is suitable for sample pretreatment in environmental protection, chemical, food, pharmaceutical and other industries. It can realize the simultaneous digestion and acid removal, shorten the pretreatment time for element detection. Generally, 2 ml of acid solution can be evaporated to the size of a soybean in 1 hour, which improves the detection efficiency.

[0069] When the output end of the telescopic drive 9 is raised, it can rest against the top of the second cavity 5 and push the test tube 4 out of the first cavity 2. The camera 7 can capture the pushed-up test tube 4. At this time, the digestion and acid removal process inside the test tube 4 can be understood through the image transmitted by the camera 7, so that the operator can understand the digestion and acid removal status. The robotic arm 6, the telescopic drive 9 and the camera 7 can be connected to the visualization control device to visualize the reaction process with the help of electronic information, which is beneficial to the health of the operator.
