[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figure 1-9The utility model provides an automatic acid adding device for soil sample digestion, comprising:

[0028] A support assembly, the support assembly includes a glass container base 200, a lifting mechanism 100 is disposed on the bottom surface of the glass container base 200, a controller 500 is fixedly connected to the glass container base 200, and the lifting mechanism 100 is electrically connected to the controller 500;

[0029] The filling component includes an acid container 300 and a dropper mechanism 400. The acid container includes a concentrated sulfuric acid container 310 and a perchloric acid container 320. The concentrated sulfuric acid container 310 and the perchloric acid container 320 are fixedly connected in a glass container. The dropper mechanism 400 includes an electrically controlled glass dropper. The electrically controlled glass dropper includes a plurality of electrically controlled glass single droppers 410, a plurality of electrically controlled glass triple droppers 420 and an electrically controlled switch. The bottom surface of the concentrated sulfuric acid container 310 is connected with a plurality of electrically controlled glass single droppers 410 and a plurality of electrically controlled glass triple droppers 420. The bottom surface of the perchloric acid container 320 is connected with a plurality of electrically controlled glass single droppers 410 and a plurality of electrically controlled glass triple droppers 420. Both the electrically controlled glass single dropper 410 and the electrically controlled glass triple dropper 420 are provided with magnetically controlled switches, and the magnetically controlled switches are electrically connected to the controller 500.

[0030] The glass container base 200 is used to place the concentrated sulfuric acid container 310 and the perchloric acid container 320. The lifting mechanism 100 can be controlled by the controller 500. The lifting mechanism 100 drives the glass container base 200 to rise or fall. During the experiment, the glass container base 200 can be raised when acid is not needed, and dropped when acid is needed. The bottom surface of the concentrated sulfuric acid container 310 is connected to a plurality of electrically controlled glass single droppers 410 and a plurality of electrically controlled glass triple droppers 420. The bottom surface of the perchloric acid container 320 is also connected to a plurality of electrically controlled glass single droppers 410 and a plurality of electrically controlled glass triple droppers 420. Figure 3 and Figure 7 It can be seen that the electrically controlled glass single dropper 410 and the electrically controlled glass triple dropper 420 are placed crosswise and side by side, and concentrated sulfuric acid and perchloric acid solutions can be dripped out at the position of each digestion tube, which is more convenient to use. The electrically controlled switch is used to control the dripping of the solution, and the controller 500 can control the opening or closing of the electrically controlled switch.

[0031] A further optimized solution is provided, wherein the electrically controlled single glass dropper 410 and the electrically controlled triple glass dropper 420 both have a tube body, and the magnetically controlled switch 430 comprises a glass tube 431, the glass tube 431 is fixedly connected to the tube body, the glass tube 431 is communicated with the tube body, the glass tube 431 is communicated with a conical nozzle, the glass tube 431 is vertically arranged to the tube body, an electrically controlled strong magnet 432 and a permanent weak magnet 433 are respectively fixedly connected at both ends of the glass tube 431, a glass-clad iron 434 is movably arranged in the glass tube 431, and the electrically controlled strong magnet 432 is electrically connected to the controller 500.

[0032] The electrically controlled glass single dropper 410 has a single tube body, and the electrically controlled glass triple dropper 420 has three tube bodies, which are connected together by a connecting tube. The solution drips out through a conical nozzle, and the conical nozzle is connected to the side of the glass tube 431 away from the tube body. The glass-clad iron 434 has a glass outer layer and an iron core inside. When the electrically controlled strong magnet 432 is not energized, the electrically controlled strong magnet 432 has no magnetism, and the glass-clad iron 434 is attracted by the permanent weak magnet 433. At this time, the glass-clad iron 434 blocks the tube body and no liquid drips. When the electrically controlled strong magnet 432 is energized, the glass-clad iron 434 moves to the side of the electrically controlled strong magnet 432, the tube body is unobstructed, and the liquid can flow down and drip out from the conical nozzle.

[0033] According to a further optimization scheme, the glass tube 431 is eccentrically arranged on the tube body, and the length of the glass-clad iron 434 is larger than the inner diameter of the tube body.

[0034] The permanent weak magnet 433 on the glass tube 431 is closer to the tube body. When the electrically controlled strong magnet 432 is not energized, the glass-coated iron 434 is on the side of the permanent weak magnet 433, thereby blocking the tube body and preventing the solution from dripping. After the electrically controlled strong magnet 432 is energized, the glass-coated iron 434 moves to the side of the electrically controlled strong magnet 432, thereby connecting the tube body and the conical nozzle, and the solution can drip out.

[0035] According to a further optimized solution, the glass container base 200 includes a bottom plate 220 , a plurality of guard plates 210 are fixedly connected to the bottom plate 220 , a plurality of observation ports 230 are opened on the guard plates 210 , and a transparent plate is inlaid on the observation ports 230 .

[0036] The observation port 230 is convenient for observing the amount of concentrated sulfuric acid and perchloric acid solution. The concentrated sulfuric acid container 310 and the perchloric acid container 320 are placed in the protective plate 210.

[0037] A further optimized solution is that the lifting mechanism 100 has four electric telescopic rods 120, two of which are fixedly connected to a fixed base 110, the output ends of the electric telescopic rods 120 are fixedly connected to a top support 130, the top support 130 is fixedly connected to the bottom plate 220, and the electric telescopic rods 120 are electrically connected to the controller 500.

[0038] The controller 500 controls the lifting and lowering of the electric telescopic rod 120 , and the top support 130 is used to connect to the bottom plate 220 .

[0039] According to a further optimization scheme, the concentrated sulfuric acid container 310 is provided with a liquid replenishing port 330, to which a frosted cover 331 is detachably connected, and the perchloric acid container 320 is provided with a liquid replenishing port 2, to which a frosted cover 2 is detachably connected.

[0040] Concentrated sulfuric acid solution is added into the concentrated sulfuric acid container 310 through the liquid replenishing port 1 330, and the frosted cover 1 331 is covered on the liquid replenishing port 1 330. Perchloric acid solution is added into the perchloric acid container 320 through the liquid replenishing port 2, and the frosted cover 2 is covered on the liquid replenishing port 2.

[0041] According to a further optimized solution, the controller 500 has an electronic integrated box 510 , and a plurality of switch buttons 520 are arranged on the electronic integrated box 510 .

[0042] The switch button 520 facilitates controlling the device.

[0043] The method of using the device is to first add concentrated sulfuric acid solution into the concentrated sulfuric acid container 310 through the liquid replenishing port 1 330, and add perchloric acid solution into the perchloric acid container 320 through the liquid replenishing port 2, and place the device above the digestion tube, so that the conical nozzles of the electric-controlled glass single dropper 410 and the electric-controlled glass triple dropper 420 are aligned with the digestion tube below, and the arrangement of the electric-controlled glass single dropper 410 and the electric-controlled glass triple dropper 420 is as follows: Figure 7 As shown, the magnetically controlled switch 430 on the electrically controlled glass single dropper 410 and the electrically controlled glass triple dropper 420 is controlled by the controller 500. When concentrated sulfuric acid solution and perchloric acid solution need to be added, the magnetically controlled switch 430 is controlled by the controller 500. When the electrically controlled strong magnet 432 is not energized, the electrically controlled strong magnet 432 has no magnetism, and the glass-coated iron 434 is attracted by the permanent weak magnet 433. At this time, the glass-coated iron 434 blocks the electrically controlled glass single dropper 410 or the electrically controlled glass triple dropper 420, and the solution does not drip. When the electrically controlled strong magnet 432 is energized, the glass-coated iron 434 moves to the side of the electrically controlled strong magnet 432, the tube body is unobstructed, and the liquid can flow down and drip out from the conical nozzle.

[0044] The device can accurately control the amount of concentrated sulfuric acid and perchloric acid added through the magnetic switch 430. After the preliminary program setting, the amount of acid added each time can be controlled to be certain. The concentrated sulfuric acid container 310 and the perchloric acid container 320 are used to separate the concentrated sulfuric acid and perchloric acid, and the perchloric acid container is made of dark glass. The dropper mechanism can accurately connect the 16 digestion tubes on the digestion furnace to ensure that the amount of acid added each time is certain and the time of adding is the same.
