Figure 6The schematic diagram of the cross-section structure of the first special-shaped heat sink 10 is shown in the figure. The first special-shaped heat sink 10 is set as a cavity structure.

Figure 7 The cross-sectional structural schematic diagram of the second special-shaped heat sink 11 is shown in the figure, in which the second special-shaped heat sink 11 is arranged as a cavity structure, and the water outlet end of the second circulation pipeline 13 bypasses the entire cavity of the second special-shaped heat sink 11 in a serpentine manner; the water outlet end of the second circulation pipeline 13 successively passes through the planar part and the cylindrical part of the support seat 8 and is connected to the water reservoir.

[0038] Compared with the prior art, the present invention combines a heat dissipation mechanism, and cold water flows in a serpentine manner in the circulation pipeline, which fully extends the flow path of the cold water in the polymerization kettle, and can more effectively remove the heat generated by the chloroprene monomer during the polymerization reaction in a timely manner.

[0039] In order to further improve the heat dissipation effect of the heat dissipation mechanism in the second embodiment, it is necessary to ensure that the first special-shaped heat dissipation rod 10 and the second special-shaped heat dissipation rod 11 move back and forth when dissipating the polymerizing chloroprene monomer; for this purpose, this embodiment also provides a first driving unit, and a more specific implementation of the first driving unit is as follows.

[0040] One implementation of the first driving unit is as follows (not limited to the implementation of the first driving unit described here): Figure 8 , which is a schematic diagram of the installation structure of the first drive unit. It can be seen from the figure that the first drive unit is connected to the output shaft of the motor 4, and the two output ends of the first drive unit are respectively connected to the first special-shaped radiator rod 10 and the second special-shaped radiator rod 11 to form a transmission connection. The first drive unit is used to drive the first special-shaped radiator rod 10 and the second special-shaped radiator rod 11 to reciprocate. Specifically, further combined with Figure 9-10 ,in, Fig. 9 is a schematic diagram of a first driving unit's three-dimensional structure from a first viewing angle, Fig.101 is a schematic diagram of the second perspective three-dimensional structure of the first drive unit, which includes a rotating disk 14, which is fixedly connected to the output shaft of the corresponding motor 4 in a concentric manner, and a slide rail 16 is sleeved and connected on the eccentric column 15 at the edge of the rotating disk 14; a connecting rod 18 at the bottom of the slide rail 16 is connected to the bearing plate 17 in a vertical sliding manner, and the other end of the bearing plate 17 is fixedly connected to the plane portion of the support seat 8, and a U-shaped flange is formed at the bottom of the connecting rod 18; a groove body 19 is fixedly connected to the bearing plate 17 on one side of the flange, and a pin shaft 20 is connected to the left and right sides of the groove body 19 respectively, and a track plate 21 (such as Fig.11 A schematic diagram of the three-dimensional structure of the track plate 21 is shown in the figure); a curved slide 22 is formed on a single track plate 21, and the curved slide 22 gradually extends from the inside to the outside, and the curved slides 22 formed on the two track plates 21 together form a forked "eight" shape; a push-pull plate 23 is rotatably connected to the bottom of the track plate 21, and the push-pull plate 23 is fixedly connected to the outer wall of the first special-shaped heat dissipation rod 10 or the second special-shaped heat dissipation rod 11 on the adjacent side; limiting columns 24 are respectively formed on the left and right sides of the flange, and the limiting columns 24 are slidably connected to the curved slide 22 on the adjacent side; at the same time, the following is made: when the eccentric column on the rotating disk 14 When the eccentric column 15 on the rotating disk 14 drives the slide rail 16 and the connecting rod 18 to move to the highest point, the flange of the connecting rod 18 uses the two limit columns 24 to move the bottom of the two track plates 21 away from each other until the forked angle of the two track plates 21 is maximum; and when the eccentric column 15 on the rotating disk 14 drives the slide rail 16 and the connecting rod 18 to move to the lowest point, the flange of the connecting rod 18 uses the two limit columns 24 to move the bottom of the two track plates 21 toward each other until the forked angle of the two track plates 21 is minimum; during the process of moving toward and away from each other, the two track plates 21 indirectly drive the first special-shaped heat sink 10 and the second special-shaped heat sink 11 to reciprocate respectively.

[0041] The working principle of the first driving unit is as follows: first, Fig. 9As shown in, under the driving action of the motor 4, the rotating disk 14 and the eccentric column 15 rotate along the direction a, and the eccentric column 15 carries the slide rail 16 and the connecting rod 18 to reciprocate upward (in the direction a1) and downward (in the direction a2) during the rotation; then, when the flange of the connecting rod 18 moves upward, the two limit columns 24 drive the two track plates 21 on the left and right sides to rotate in opposite directions along the directions c1 and c2 respectively (the two track plates 21 are gradually in a forked state at this time); and when the flange of the connecting rod 18 moves downward, the two limit columns 24 drive the two track plates 21 on the left and right sides to rotate in the directions c2 and c1 respectively (the two track plates 21 are gradually in a closed state at this time); finally, during the reciprocating rotation and swinging process of the track plate 21, the push-pull plate 23 on the track plate 21 drives the corresponding first special-shaped heat dissipation rod 10 or the second special-shaped heat dissipation rod 11 to reciprocate, When the first special-shaped heat dissipation rod 10 and the second special-shaped heat dissipation rod 11 move back and forth, sufficient heat dissipation of the chloroprene monomer in polymerization is achieved, thereby further improving the heat dissipation effect of the heat dissipation mechanism of the present invention.

[0042] Embodiment 2, this embodiment provides a rapid heat exchange system, which includes the rapid heat exchange polymerization kettle shown in Embodiment 1. In order to further improve the heat dissipation efficiency, this embodiment is optimized as follows: a stirring mechanism is provided on the kettle cover 1 on the left side and a heat dissipation mechanism is provided in the kettle, and a stirring mechanism is provided on the kettle cover 1 on the right side and a heat dissipation mechanism is provided in the kettle; of course, in actual design, stirring mechanisms can also be provided on the kettle covers 1 on multiple sides and heat dissipation mechanisms can be provided in the kettle; on the other hand, during the long-term use of the motor 4, a large amount of dust will cover the shaft of the motor 4, which will inevitably affect the rotation of the shaft of the motor 4; for this reason, the present invention further designs a dust removal mechanism, and the specific structure of the dust removal mechanism is as follows.

[0043] The first embodiment of the dust removal mechanism directly uses a commercially available exhaust fan, which is fixed to the base 5 by bolts, and the air outlet of the exhaust fan is opposite to the shaft of the motor 4; this embodiment of the dust removal mechanism is not shown in the figure.

[0044] The second embodiment of the dust removal mechanism, refer to Figure 12-14 , Fig.12 The figure shows the installation structure diagram of the second embodiment of the dust removal mechanism. Fig.13 The figure shows a partial installation structure diagram of the second embodiment of the dust removal mechanism. Fig.14What is shown is a schematic diagram of the three-dimensional structure of the second embodiment of the dust removal mechanism. It can be seen from the above figure that the dust removal mechanism includes a cylinder 25, a support arm 26 is formed on the outer wall of the cylinder 25, and the other end of the support arm 26 is fixedly connected to the base 5; a rotating shaft 27 is rotatably connected at the center of the cylinder 25, and a transmission gear 28 is concentrically fixedly connected to the rotating shaft 27, and a tooth plate 29 is meshed and linked on the transmission gear 28, and a sliding arm 30 of the tooth plate 29 is slidably connected in a slide groove 31, and the slide groove 31 is fixedly connected to one end of the cylinder 25 by welding; a cleaning brush 32 is fixedly connected to the end of the sliding arm 30; it is also defined that: when the tooth plate 29 reciprocates, the bristles of the cleaning brush 32 reciprocate on the shaft of the motor 4, thereby realizing dust cleaning; a second driving unit for driving the rotating shaft 27 to rotate is installed in the cylinder 25, and the more specific structure of the second driving unit is as follows.

[0045] refer to Fig.15 , which is a schematic diagram of the installation structure of the second drive unit in the cylinder 25. It can be seen from the figure that the second drive unit includes a turbine 33, which is concentrically fixed on the rotating shaft 27 in the cylinder 25. An elastic component 34 (such as a spring, etc.) is connected to the turbine 33, and the other end of the elastic component 34 is connected to the cylinder 25; the cylinder 25 is connected to a liquid inlet 35 and a liquid outlet 36 respectively, and the liquid inlet 35 is connected to the first circulation pipeline 12 or the second circulation pipeline 13, and the liquid outlet 36 is also connected to the first circulation pipeline 12 or the second circulation pipeline 13. When in use, first, the pump body is started and shut down intermittently and cyclically, so that cold water enters the cylinder 25 intermittently; once the cold water enters the cylinder 25 at a high speed and impacts the turbine 33, the turbine 33 rotates under the action of the water pressure; and once the cold water stops entering the cylinder 25, the turbine 33 is no longer constrained by the water pressure and returns to its original position under the action of the elastic component 34; the turbine 33 drives the rotating shaft 27 to reciprocate clockwise and counterclockwise during the left and right reciprocating swing. Then, the rotating shaft 27 sequentially links the transmission gear 28, the tooth plate 29, the sliding arm 30, and the cleaning brush 32 to reciprocate, so that in the process of heat dissipation by the heat dissipation mechanism, the cleaning brush 32 can also be indirectly linked to achieve cleaning and dust removal operations on the shaft of the motor 4.

[0046] As an optimization solution for the second drive unit, refer to Figure 14-15 A fan blade 37 is concentrically sleeved on the rotating shaft 27 disposed outside the cylinder 25, so that when the cleaning brush 32 cleans the shaft of the motor 4, the rotating fan blade 37 can also be used to blow away the dust.

[0047] As an optimization solution for the present invention, Figure 3As shown in the figure, a mutually fitting sliding fit can be formed between the outer wall of the first special-shaped heat sink 10 and the outer wall of the second special-shaped heat sink 11, so that when the first special-shaped heat sink 10 and the second special-shaped heat sink 11 contact each other, the colloid on the surface of the first special-shaped heat sink 10 or the second special-shaped heat sink 11 is scraped off, thereby improving the heat dissipation efficiency.

[0048] In addition, see Figure 2 A heat exchange device is provided on the kettle cavity 2 and the kettle bottom 3 of the kettle body. The heat exchange system includes a jacket 38. The jacket 38 is installed on the outer wall of the kettle body. There is a gap between the jacket 38 and the kettle cavity 2 and the kettle bottom 3; and a refrigerant inlet 39 and a refrigerant outlet 40 are respectively connected on one side of the jacket 38 (for example, the refrigerant can be cooling brine). The cooling brine enters from the refrigerant inlet 39 through the pump body and flows through the inner wall of the jacket 38, and finally the cooling brine flows out from the refrigerant outlet 40; according to the amount of heat generated in the kettle body, the terminal controller is used to intelligently control the amount of refrigerant flow in the jacket and the amount of cold medium flow in the circulation pipeline.

[0049] In the heat exchange process of the present invention, the stirring mechanism with adjustable speed adjusts the speed in the kettle body according to the intelligent interlocking to reduce the temperature in the kettle body. The heat exchange equipment of the external circulation on the outer wall of the kettle body uses at least one stage of heat exchange to fine-tune the heat exchange, and intelligently adjusts the level of heat exchange according to the heat of the kettle body, so that the heat in the kettle body operates within the normal range. If the heat exchange equipment on the outer wall of the kettle body cannot meet the heat exchange requirements, the heat dissipation mechanism of at least one stage of large-capacity refrigerant installed on the kettle cover starts to operate and take away the heat of the kettle body, so that the heat in the kettle body operates within the normal range, thereby realizing multi-configuration intelligent interlocking automatic and rapid heat exchange and achieving precise temperature control.
