[0015] As an improved technical solution, one end of the bearing rod away from the bearing arm is fixedly installed with a convex column, and the convex column is movably connected to the transparent measuring cylinder.

[0016] As an improved technical solution, a groove column is fixedly installed on the outer surface of the transparent measuring cylinder, and the groove on the groove column is rotatably connected to the outer surface of the convex column.

[0034] Refer to Figures 1-4 , a production synthesis device for aluminum diethylphosphinate is provided. In this production synthesis device for aluminum diethylphosphinate, there is a reaction kettle 1, and the reaction kettle 1 is used for carrying out reactions;

[0035] An inverted L-shaped plate 2 is provided on the reaction kettle 1;

[0036] A rotating structure 3 is provided on the inverted L-shaped plate 2, and the rotating structure 3 is used for rotating and adjusting the position;

[0037] A transparent measuring cylinder 4 is provided on the rotating structure 3, and the transparent measuring cylinder 4 is used for accurately quantitatively adding diethylphosphinic acid;

[0038] An opening and closing structure 5 is provided on the transparent measuring cylinder 4, and the opening and closing structure 5 is used for automatic feeding.

[0039] The rotating structure 3 includes a driving motor 31, which is fixedly connected to the inverted L-shaped plate 2. An output shaft 32 is provided on the driving motor 31. The output shaft 32 penetrates through the inside of the inverted L-shaped plate 2, and a bearing arm 33 is fixedly sleeved on the outer surface of the protruding part.

[0040] A bearing rod 34 is fixedly installed at one end of the bearing arm 33 away from the output shaft 32. The end of the bearing rod 34 away from the bearing arm 33 is movably connected to the transparent measuring cylinder 4. By starting the driving motor 31, at this time, the output shaft 32 on the driving motor 31 drives the bearing arm 33 to rotate, the bearing arm 33 drives the bearing rod 34 to rotate, and the bearing arm 33 on the side away from the driving motor 31 rotates around the rotating shaft 35 until the transparent measuring cylinder 4 is rotated directly above the reaction kettle 1, so as to conveniently rotate and adjust the quantified diethylphosphonic acid directly above the reaction kettle 1, and further facilitate automatic feeding.

[0041] The rotating structure 3 further includes a rotating shaft 35. One end of the rotating shaft 35 is fixedly connected to the inverted L-shaped plate 2. The outer surface of the rotating shaft 35 is rotatably sleeved with the inside of the bearing arm 33. By rotating the bearing arm 33 on the side away from the driving motor 31 around the rotating shaft 35, the quantified diethylphosphonic acid can be rotated and adjusted directly above the reaction kettle 1.

[0042] A convex column 341 is fixedly installed at the end of the bearing rod 34 away from the bearing arm 33. The convex column 341 is movably connected to the transparent measuring cylinder 4 to facilitate the connection between the bearing rod 34 and the transparent measuring cylinder 4.

[0043] A groove column 41 is fixedly installed on the outer surface of the transparent measuring cylinder 4. The groove on the groove column 41 is rotatably connected to the outer surface of the convex column 341 to facilitate the rotation of the convex column 341 in the groove cavity of the groove on the groove column 41.

[0044] The diameter and size of the groove cavity on the groove column 41 are both adapted to the diameter and size of the outer surface of the convex column 341 to ensure that the convex column 341 rotates more smoothly in the groove on the groove column 41.

[0045] The opening and closing structure 5 includes a fixed plate 51, which is fixedly connected to the outer surface of the transparent metering cylinder 4. A micro stepping motor 52 is fixedly installed on the fixed plate 51. The output shaft of the micro stepping motor 52 penetrates through the inside of the fixed plate 51, and a connecting plate 53 is fixedly sleeved on the outer surface of the extended part. A baffle 54 is fixedly installed on the connecting plate 53, and the baffle 54 is movably connected to the bottom end of the transparent metering cylinder 4. By starting the micro stepping motor 52, the output shaft of the micro stepping motor 52 drives the connecting plate 53 to rotate at this time, and the connecting plate 53 drives the baffle 54 to rotate until the baffle 54 does not block the inner cavity of the transparent metering cylinder 4. At the same time, the quantified diethyl phosphite in the transparent metering cylinder 4 automatically drops into the reaction kettle 1 for reaction, so that diethyl phosphite can be accurately quantified and added, which is conducive to the reaction of the reactants and the improvement of the dissolution rate.

[0046] The cross section of the baffle 54 is circular, and the outer surface diameter of the baffle 54 is larger than the inner cavity diameter of the transparent metering cylinder 4, so as to facilitate the baffle 54 to block the inner cavity of the transparent metering cylinder 4 and prevent the quantified diethyl phosphite from leaking.

[0047] Working principle: By putting the quantified diethyl phosphite into the transparent metering cylinder 4, and then starting the driving motor 31 fixed on the inverted L-shaped plate 2. At this time, the output shaft 32 of the driving motor 31 drives the bearing arm 33 to rotate, the bearing arm 33 drives the bearing rod 34 to rotate, and the bearing arm 33 on the side far from the driving motor 31 rotates around the rotating shaft 35 until the transparent metering cylinder 4 is rotated directly above the reaction kettle 1. During this period, due to the weight of the transparent metering cylinder 4 and the quantified diethyl phosphite, the convex column 341 rotates in the groove inner cavity of the groove column 41, and the transparent metering cylinder 4 always keeps vertically downward during the rotation process, so as to facilitate the rotation adjustment of the quantified diethyl phosphite directly above the reaction kettle 1, and then facilitate automatic feeding;

[0048] Then, by starting the micro stepping motor 52 fixed on the fixed plate 51, the output shaft of the micro stepping motor 52 drives the connecting plate 53 fixed on the output shaft to rotate at this time, and the connecting plate 53 drives the baffle 54 to rotate until the baffle 54 does not block the inner cavity of the transparent metering cylinder 4. At the same time, the quantified diethyl phosphite in the transparent metering cylinder 4 automatically drops into the reaction kettle 1 for reaction, so that diethyl phosphite can be accurately quantified and added, which is conducive to the reaction of the reactants and the improvement of the dissolution rate. This device can not only accurately quantify and add diethyl phosphite, but also is conducive to the reaction of the reactants and the improvement of the dissolution rate.

In addition, it should also be understood that after reading the technical content of the present utility model, those skilled in the art can make various changes, modifications and / or variations to the present utility model, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
