Figure 6 The 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. The water outlet end of the first circulation pipe 12 bypasses the entire cavity of the first special-shaped heat sink 10 in a serpentine manner; the water outlet end of the first circulation pipe 12 sequentially passes through the flat part and the cylindrical part of the support base 8 and is connected to the water reservoir. The water inlet end of the second circulation pipe 13 is connected to the water reservoir filled with cold water. The cold water in the water reservoir is pumped into the water inlet end of the second circulation pipe 13 through the pump body (the water reservoir and the pump body are not shown in the figure); the water outlet end of the second circulation pipe 13 sequentially passes through the cylindrical part and the flat part of the support base 8, as shown in FIG. Figure 7 The cross-sectional structural diagram of the second special-shaped heat sink 11 is shown in the figure. The second special-shaped heat sink 11 is set 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 passes through the planar part and the cylindrical part of the support seat 8 in sequence and is connected to the water tank.

[0039] By combining a heat dissipation mechanism, compared with the prior art, the present invention enables cold water to flow in a serpentine manner in the circulation pipeline, fully extending the flow path of the cold water in the polymerization kettle, and can more effectively and timely remove the heat generated by the chloroprene monomer during the polymerization reaction.

[0040] 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 heat of 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.

[0041] One embodiment of the first driving unit is as follows (not limited to the embodiment of the first driving unit exemplified here): Figure 8The figure shows 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, Figure 9 is a schematic diagram of the first driving unit's three-dimensional structure from a first viewing angle, Figure 10 Schematic diagram of the second perspective structure of the first drive unit, the first drive unit includes a rotating disk 14, the rotating disk 14 is fixedly connected to the output shaft of the corresponding motor 4 in a concentric manner, and the eccentric column 15 on the edge of the rotating disk 14 is sleeved with a slide rail 16; the connecting rod 18 at the bottom of the slide rail 16 is connected to the supporting plate 17 in a vertical sliding manner, and the other end of the supporting plate 17 is fixedly connected to the flat portion of the support seat 8, and the bottom of the connecting rod 18 is formed with a U-shaped flange; a groove 19 is fixedly connected to the supporting plate 17 on one side of the flange, and a pin 20 is connected to the left and right sides of the groove 19 respectively, and a track plate 21 (as shown in FIG. Figure 11 A schematic diagram of the three-dimensional structure of the track plate 21 is shown in FIG); a curved slide 22 is formed on the 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; the bottom of the track plate 21 is rotatably connected to a push-pull plate 23, 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 15 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 bottoms 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 bottoms of the two track plates 21 toward each other until the forked angle of the two track plates 21 is minimum; in the process of moving toward each other 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 move back and forth respectively.

[0042] The working principle of the first driving unit is as follows: first, Figure 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 move up (in the direction a1) and down (in the direction a2) in the process of rotation; then, when the flange of the connecting rod 18 moves upward, the two limiting 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 at this time gradually become a forked state); and when the flange of the connecting rod 18 moves downward, the two limiting columns 24 drive the two track plates 21 on the left and right sides to rotate toward each other along the directions c2 and c1 respectively (the two track plates 21 at this time gradually become a closed state); 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 move back and forth, When the first special-shaped heat dissipation rod 10 and the second special-shaped heat dissipation rod 11 move back and forth, they can fully dissipate the heat of the chloroprene monomer being polymerized, thereby further improving the heat dissipation effect of the heat dissipation mechanism of the present invention.

[0043] Example 2. This example provides a rapid heat exchange system, which includes the rapid heat exchange polymerization kettle shown in Example 1. In order to further improve the heat dissipation efficiency, this example 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 inside the kettle, and a stirring mechanism is provided on the kettle cover 1 on the right side and a heat dissipation mechanism is provided inside 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 also be provided inside 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.

[0044] The first embodiment of the dust removal mechanism directly uses an exhaust fan available on the market. The exhaust fan is fixedly connected to the machine 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.

[0045] The second embodiment of the dust removal mechanism, refer to Figure 12-14 , Figure 12 The figure shows the installation structure diagram of the second embodiment of the dust removal mechanism. Figure 13 The figure shows a partial installation structure diagram of the second embodiment of the dust removal mechanism. Figure 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, an outer wall of the cylinder 25 is formed with a support arm 26, the other end of the support arm 26 is fixedly connected to the machine base 5; a rotary shaft 27 is rotatably connected to the center of the cylinder 25, and a transmission gear 28 is concentrically fixedly connected to the rotary shaft 27, and a toothed plate 29 is meshed and linked on the transmission gear 28, and a sliding arm 30 of the toothed plate 29 is slidably connected in the 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 stipulated that: when the toothed plate 29 moves back and forth, the bristles of the cleaning brush 32 move back and forth on the shaft of the motor 4, thereby realizing dust cleaning; a second drive unit for driving the rotary shaft 27 to rotate is installed in the cylinder 25, and the more specific structure of the second drive unit is as follows.

[0046] refer to Figure 15 , which is a schematic diagram of the installation structure of the second drive unit in the cylinder 25. As can be seen from the figure, 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 respectively connected to a liquid inlet 35 and a liquid outlet 36, and the liquid inlet 35 is connected to the first circulation pipeline 12 or the second circulation pipeline 13. Similarly, the liquid outlet 36 is connected to the first circulation pipeline 12 or the second circulation pipeline 13. During use, the pump is first started and shut down intermittently, allowing cold water to enter the cylinder 25 intermittently. Once the cold water enters the cylinder 25 at high speed and impacts the turbine 33, the turbine 33 rotates under the action of the water pressure. Once the cold water stops entering the cylinder 25, the turbine 33, no longer constrained by the water pressure, returns to its original position under the action of the elastic member 34. The turbine 33 then swings back and forth, driving the rotating shaft 27 to reciprocate clockwise and counterclockwise. The rotating shaft 27 then sequentially drives the transmission gear 28, the toothed plate 29, the sliding arm 30, and the cleaning brush 32 to reciprocate. This allows the cooling mechanism to dissipate heat while indirectly driving the cleaning brush 32 to clean and remove dust from the shaft of the motor 4.

[0047] 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 placed on the outside of 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.

[0048] As an optimization solution of the present invention, Figure 3As shown in the figure, a 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.

[0049] Also, 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. 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. 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 refrigerant flow in the jacket and the refrigerant flow in the circulation pipeline.

[0050] During the heat exchange process, the present invention uses an adjustable speed stirring mechanism to adjust the speed of the kettle body according to the intelligent interlocking to reduce the temperature inside the kettle body. The heat exchange equipment on the outer wall of the kettle body uses at least one stage of heat exchange to fine-tune the heat exchange. According to the heat of the kettle body, the level of heat exchange is intelligently adjusted to keep the heat inside the kettle body within a 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 with at least one stage of large-capacity refrigerant installed on the kettle cover starts to operate and takes away the heat of the kettle body, so that the heat inside the kettle body operates within a normal range, thereby realizing multi-configuration intelligent interlocking automatic and rapid heat exchange and achieving precise temperature control.
