[0021] Step 1: Programming and controlling the servo motor, the servo motor drives the first rotating shaft to rotate, driving the loading plate, the loading box assembly and the sealing plug assembly to rotate. When the loading box assembly rotates to the bottom of the feeding pipe, the servo motor stops working. At the same time, under the action of the connecting plate mechanism, the interior of the loading box assembly is exposed, the first solenoid valve is opened, and dimethylpropylenediamine liquid is quantitatively input into the loading box assembly directly below through the feeding pipe, wherein the delivery pipe is used to connect the production equipment and storage equipment of the dimethylpropylenediamine liquid, and then the servo motor continues to work, driving the loading plate mechanism to rotate clockwise. During the process, under the action of the connecting plate mechanism, the interior of the loading box assembly is closed;

[0022] Step 2, when the loading box assembly filled with dimethylpropylenediamine liquid rotates to the rear end, the servo motor stops working, and at the same time, under the action of the adapter plate mechanism, the interior of the loading box assembly is exposed again, and the concentration analysis mechanism performs concentration analysis and detection on the dimethylpropylenediamine liquid in the loading box assembly. After the detection, the servo motor works again to drive the loading plate mechanism to rotate clockwise. During the process, under the action of the adapter plate mechanism, the interior of the loading box assembly is closed again. When the loading box assembly rotates to the rightmost end, the servo motor stops working again, and at the same time, under the action of the adapter plate mechanism, the interior of the loading box assembly is exposed. At the same time, under the push of the arc-shaped protrusion, the sealing plug assembly directly below the loading box assembly is pushed upward to expose the discharge hole, and the dimethylpropylenediamine liquid in the loading box assembly flows into the bottom barrel through the discharge hole. At the same time, the second solenoid valve on the water pipe is opened. Since the right end of the water pipe is connected to the external water source, the external water source is sucked into the water pipe by the external pump body, and the loading box assembly directly below is flushed through the nozzle. The flushing water flows into the bottom barrel and is finally discharged through the sewage pipe;

[0023] Step three, after rinsing, the servo motor works again, driving the loading plate mechanism to rotate clockwise. During the process, under the joint action of the connecting plate mechanism and the arc-shaped protrusion, the interior of the loading box assembly continues to be exposed, and the discharge hole is also exposed. The second solenoid valve on the air pipe is opened. Since the right end of the air pipe is connected to the external hot air blower, the hot air generated by the external hot air blower passes through the air pipe and the arc-shaped hollow plate and blows out into the loading box assembly just below the arc-shaped hollow plate to dry the interior of the loading box assembly. After the drying process is completed, the loading box assembly continues to rotate and rotates again to just below the discharge pipe to enter the next cycle operation.

[0024] Beneficial Effects

After the test is completed, the interior of the loading plate mechanism can be automatically rinsed and dried in time to complete continuous automatic operation, improve work efficiency, avoid sample residue, and ensure the accuracy of the re-sampling test results.

[0027] 2. A dimethylpropylenediamine concentration analysis device and method, through the mutual cooperation between the discharge hole, the sealing plug rod, the semicircular block, the second spring and the arc-shaped protrusion, when the loading box assembly and the corresponding sealing plug assembly are rotated to the bottom of the nozzle or the arc-shaped hollow plate, the semicircular block and the sealing plug rod will be moved up under the push of the arc-shaped protrusion, and then the discharge hole will be automatically exposed, so that the dimethylpropylenediamine liquid detected in the receiving chamber will automatically flow downward through the discharge hole, and the water flushed into the receiving chamber will also automatically flow out along the discharge hole, so that the cleaned receiving chamber can be quickly dried later to avoid residual water stains interfering with the concentration detection result. The waste water is uniformly discharged to the designated external location through the sewage pipe, which is more convenient to use.

[0028] 3. A device and method for analyzing dimethylpropylenediamine concentration. Through the cooperation of a sealing plate, a through port, a first spring, a protrusion, a second trapezoidal block and a third trapezoidal block, when the loading box assembly rotates with the loading disk, when there is no need to operate the interior of the accommodating chamber, the sealing plate covers the top of the accommodating chamber under the elastic action of the first spring to prevent the pungent odor of the dimethylpropylenediamine liquid in the accommodating chamber from emitting. When it is necessary to operate the interior of the accommodating chamber, the sealing plate is moved under the push of the second trapezoidal block or the third trapezoidal block to connect the through port with the interior of the accommodating chamber. The interior of the accommodating chamber can be operated through the through port, thereby preventing the dimethylpropylenediamine liquid in the accommodating chamber from being exposed to the outside all the time and reducing the emission of pungent odor.

[0029] 4. A device and method for analyzing the concentration of dimethylpropylenediamine. Through the cooperation between the vertical rod, the detection probe, the third spring and the first trapezoidal block, when the loading box assembly rotates to the rear end, the detection probe is automatically pushed downward under the action of the first trapezoidal block and the vertical rod. At the same time, the protrusion cooperates with the rear second trapezoidal block to push the sealing plate so that the through port and the accommodating chamber gradually overlap. During the process, the detection probe can automatically enter the accommodating chamber through the through port to perform concentration analysis and detection on the dimethylpropylenediamine liquid in the accommodating chamber.

[0055] The embodiment of the present invention further provides a method for analyzing the concentration of dimethylpropylenediamine, using a dimethylpropylenediamine concentration analysis device, and the specific method includes the following steps:

[0056] Step 1: Program the servo motor. The servo motor drives the first rotating shaft 61 to rotate, driving the loading plate 62, the loading box assembly 64 and the sealing plug assembly 65 to rotate. When the loading box assembly 64 rotates to the bottom of the feeding tube 85, the servo motor stops working. At the same time, the inside of the loading box assembly 64 is exposed under the cooperation of the second trapezoidal block 73 on the left and the protrusion 646. During the process, the second trapezoidal block 73 on the left pushes the protrusion 646 to move left, and then pushes the sealing plate 643 to the left, so that the through port 644 overlaps with the accommodating chamber 642. Then, the first solenoid valve is controlled to open, and the dimethylpropylenediamine liquid is quantitatively input into the accommodating chamber 642 directly below through the feeding tube 85. The dimethylpropylenediamine liquid in the accommodating chamber 642 is The weight will not push the sealing plug rod 652 downward, wherein the delivery pipe 84 is used to connect the production equipment and the storage equipment of the dimethylpropylenediamine liquid, one end of the delivery pipe 84 is connected to the output end of the production equipment of the dimethylpropylenediamine liquid, and the other end of the delivery pipe 84 is connected to the input end of the storage equipment of the dimethylpropylenediamine liquid, and the dimethylpropylenediamine liquid continuously flows from the production equipment to the storage equipment through the delivery pipe 84, and then the servo motor continues to work, driving the loading plate mechanism 6 to rotate clockwise, during which the protrusion 646 is separated from the second trapezoidal block 73, and under the elastic action of the first spring 645, the sealing plate 643 returns to its original position, and the through port 644 is not connected to the accommodating chamber 642, so that the top of the accommodating chamber 642 is sealed;

[0057] Step 2, when the loading box assembly 64 filled with dimethylpropylenediamine liquid rotates to the rear end, the servo motor stops working, and at the same time, under the cooperation of the second trapezoidal block 73 and the protrusion 646 at the rear, the interior of the loading box assembly 64 is exposed again. During the process, the second trapezoidal block 73 at the rear pushes the protrusion 646 to move backward, and then pushes the sealing plate 643 backward, so that the through-port 644 and the accommodating cavity 642 gradually overlap, and the accommodating cavity 642 is exposed. At the same time, under the action of the first trapezoidal block 648 and the vertical rod 93, the first trapezoidal block 648 passes through the top of the vertical rod 93 during the rotation process, and pushes the vertical rod 93 and the detection probe 94 downward. During the process, the detection probe 94 automatically enters the accommodating chamber 642 through the opening 644 to detect the concentration of the dimethylpropylenediamine liquid in the accommodating chamber 642. The detection probe 94 belongs to the prior art known to those skilled in the art and is used to detect the concentration of the dimethylpropylenediamine liquid. The detection probe 94 transmits the detection result to the processor 91, and the processor 91 analyzes and processes the detection result. After the detection, the servo motor works again to drive the loading plate mechanism 6 to rotate clockwise. During the process, the protrusion 646 is gradually separated from the rear second trapezoidal block 73. Under the elastic action of the first spring 645, the sealing plate 643 returns to its original position. The top of the accommodating chamber 642 is sealed, and at the same time, under the elastic action of the third spring 95, the vertical rod 93 and the detection probe 94 move up to restore their original positions, and the detection probe 94 is separated from the accommodating chamber 642. No interference will occur during the process. When the loading box assembly 64 rotates to the rightmost end, the servo motor stops working again. At the same time, under the cooperation of the third trapezoidal block 74 and the protrusion 646, the interior of the loading box assembly 64 is exposed again. At the same time, under the push of the arc-shaped protrusion 5, the sealing plug rod 652 directly below the loading box assembly 64 is pushed upward to expose the discharge hole 63. During the process, due to the rotation of the semicircular block 653 In the middle, the second spring 654 is compressed under the upward push of the arc-shaped protrusion 5, so that the semicircular block 653 and the sealing plug rod 652 move upward, thereby automatically exposing the discharge hole 63, and the dimethylpropylenediamine liquid in the loading box assembly 64 flows into the bottom cylinder 2 through the discharge hole 63. At the same time, the second solenoid valve on the water pipe 86 is opened. Since the right end of the water pipe 86 is connected to the external water source, the external water source is sucked into the water pipe 86 by the external pump body, and is flushed to the accommodating chamber 642 directly below through the nozzle 87. The flushing water also flows into the bottom cylinder 2 through the discharge hole 63 and is finally discharged through the sewage pipe 3;

[0058] Step three, after rinsing, the servo motor works again, driving the loading tray mechanism 6 to rotate clockwise. During the process, the discharge hole 63 continues to be exposed under the upward push of the arc-shaped protrusion 5, and the accommodating chamber 642 continues to be exposed under the push of the third trapezoidal block 74. The second solenoid valve on the air pipe 88 is opened. Since the right end of the air pipe 88 is connected to the external hot air blower, the hot air generated by the external hot air blower passes through the air pipe 88 and the arc-shaped hollow plate 89 and blows it into the accommodating chamber 642 just below the arc-shaped hollow plate 89 to dry the interior of the accommodating chamber 642. After the drying process is completed, the loading box assembly 64 continues to rotate and rotates again to the bottom of the discharge pipe 85 to enter the next cycle operation.

A method for analyzing the concentration of dimethylpropylenediamine, characterized in that: Using the dimethylpropylenediamine concentration analysis device as claimed in claim 1, the method comprises the following steps: Step 1: Programming and controlling the servo motor, the servo motor drives the first rotating shaft (61) to rotate, driving the loading plate (62), the loading box assembly (64) and the sealing plug assembly (65) to rotate. When the loading box assembly (64) rotates to the position directly below the discharge pipe (85), the servo motor stops working. At the same time, under the action of the connecting plate mechanism (7), the interior of the loading box assembly (64) is exposed. The first solenoid valve opens, and a quantitative amount of dimethylpropylenediamine liquid is input into the loading box assembly (64) directly below through the discharge pipe (85). The delivery pipe (84) is used to connect the production equipment and storage equipment of the dimethylpropylenediamine liquid. After that, the servo motor continues to work, driving the loading plate mechanism (6) to rotate clockwise. During the process, under the action of the connecting plate mechanism (7), the interior of the loading box assembly (64) is closed. Step 2: When the loading box assembly (64) containing the dimethylpropylenediamine liquid rotates to the rear end, the servo motor stops working. At the same time, under the action of the connecting plate mechanism (7), the interior of the loading box assembly (64) is exposed again. The concentration analysis mechanism (9) performs concentration analysis on the dimethylpropylenediamine liquid in the loading box assembly (64). After the detection, the servo motor starts working again, driving the loading plate mechanism (6) to rotate clockwise. During the process, under the action of the connecting plate mechanism (7), the interior of the loading box assembly (64) is closed again. When the loading box assembly (64) rotates to the rightmost end, the servo motor stops working again. At the same time, under the action of the connecting plate mechanism (7), the loading box assembly (64) is closed again. The interior of the loading box assembly (64) is exposed, and at the same time, the sealing plug assembly (65) directly below the loading box assembly (64) is pushed upwards by the arc-shaped protrusion (5), so that the discharge hole (63) is exposed, and the dimethylpropylenediamine liquid in the loading box assembly (64) flows into the bottom cylinder (2) through the discharge hole (63). At the same time, the second solenoid valve on the water pipe (86) is opened. Since the right end of the water pipe (86) is connected to the external water source, the external water source is sucked into the water pipe (86) by the external pump body, and is flushed into the loading box assembly (64) directly below through the nozzle (87). The flushing water flows into the bottom cylinder (2) and is finally discharged through the sewage pipe (3); Step 3: After rinsing, the servo motor starts working again, driving the loading tray mechanism (6) to rotate clockwise.
