[0053] Example 3:

[0054] The present invention also discloses an online analysis method for the content of products in a continuous production process of propylenediamine, which comprises the following steps:

[0055] Step 1: First, the staff places the propylene diamine production raw materials into the inner cavity of the working box 102 from the first feed port 1021 and the second feed port 1022 respectively. When the placement is completed, the staff drives the component to stir the placed propylene diamine production raw materials;

When the rotating rod 2011 rotates three-quarters of a circle, the first sealing plate 3022 and the second sealing plate 3023 just seal the placement cylinder 302. At the same time, the rotating rod 203 can rotate three-quarters of a circle, driving the first half gear 4012 and the second half gear 4013 to rotate three-quarters of a circle, so that they can mesh with the first gear ring 4014 and the second gear ring 4015 respectively, so that The first gear ring 4014 and the second gear ring 4015 drive the first drum 401 and the second drum 4011 to rotate respectively, so that the first drum 401 and the second drum 4011 can rotate one circle for six minutes, and the collecting drum 4016 containing propylene diamine is replaced, and the next collecting drum 4016 is allowed to come over. At this time, the above steps are repeated, so that the propylene diamine production process can be continuously collected. When all the collection is completed, the staff uses the detection equipment to detect the inner cavity of the collecting drum 4016 containing propylene diamine, thereby measuring the propylene diamine product content.

[0058] The implementation principle of the online analysis device and method for product content in a continuous production process of propylenediamine in this embodiment is as follows:

[0059] First, the staff places the propylene diamine production raw materials into the inner cavity of the working box 102 from the first feeding port 1021 and the second feeding port 1022 respectively. When the placement is completed, the staff starts the servo motor 201. When the servo motor 201 is running, it can drive the rotating rod 2011 to rotate. When the rotating rod 2011 rotates, it can drive the stirring rod 2012 to rotate, so that the propylene diamine production raw materials placed in the working chamber 103 are stirred by the stirring rod 2012.

[0060] At the same time, when the rotating rod 2011 rotates, the rotating rod 2011 will be able to drive the rotating rod 202 to rotate. When the rotating rod 202 rotates, the rotating rod 202 will be able to drive the guide sleeve 2023 to move vertically downward with the assistance of the guide chute 2021, the guide slider 2022 and the guide rod 2025. When the guide sleeve 2023 moves vertically downward, it will be able to drive the two placing cylinders 302 to move vertically downward through the connecting block 2024, so that the placing cylinder 302 can leave the unloading port opened at the positioning plate;

[0062] When the movable rod 3033 rotates, the movable rod 3033 can push the first sealing plate 3022 and the second sealing plate 3023 respectively to move in opposite directions with the assistance of the third slide groove 3031 and the third slider 3032, so that the placement cylinder 302 can be opened, so that the produced propylenediamine can fall onto the collecting cylinder 4016 provided on the workbench 101 along the discharge port and the first notch 3026 and the second notch 3027 opened on the placement cylinder 302, until the rotating rod 2011 rotates half a circle, at this time the guide sleeve 2023 can move vertically upward, thereby driving the placement cylinder 302 to slowly reset, and when the rotating rod 2011 rotates three-quarters of a circle, the first sealing plate 3022 and the second sealing plate 3023 just close the placement cylinder 302, and at the same time At this time, the rotating rod 203 can rotate three-quarters of a circle, driving the first half gear 4012 and the second half gear 4013 to rotate three-quarters of a circle, so that they can engage with the first gear ring 4014 and the second gear ring 4015 respectively. Therefore, the first gear ring 4014 and the second gear ring 4015 can respectively drive the first rotating drum 401 and the second rotating drum 4011 to rotate, so that the first rotating drum 401 and the second rotating drum 4011 can rotate one-sixth of a circle, and the collecting drum 4016 containing propylene diamine is replaced, and the next collecting drum 4016 is allowed to come over. At this time, the above steps are repeated, so that the propylene diamine production process can be continuously collected. When all the collection is completed, the staff will use the detection equipment to detect the inner cavity of the collecting drum 4016 containing propylene diamine to measure the propylene diamine product content.
