Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0026] Such as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown in the figure, a silicone sealant production reactor provided by an embodiment of the present invention includes a housing 1. Inside the housing 1, there is a reactor inner tank 12. At the top of the reactor inner tank 12, there is a connecting flange 121. A top cover 13 is detachably installed on the connecting flange 121. In the cavity between the housing 1 and the reactor inner tank 12, there is a heat-conducting medium for heating the reactor inner tank 12. A liquid inlet pipe 14 is provided on the side wall of the housing 1, and a liquid discharge pipe 16 is installed at the bottom of the housing 1. It further includes:

[0027] A working module 3. The working module 3 includes a main shaft 31 disposed in the reactor inner tank 12. And on the top cover 13, there is also a driving unit 2 for driving the main shaft 31 to rotate. A number of stirring rods 32 are annularly installed on the main shaft 31. Between the stirring rods 32 in the same vertical direction, there is an auxiliary scraper 33 connected. And the auxiliary scraper 33 is slidably installed on the stirring rod 32 along the radial direction of the main shaft 31. At the upper end of the main shaft 31, there is also a sliding sleeve 34. The sliding sleeve 34 is slidably installed on the main shaft 31 along the axial direction of the main shaft 31. And on the top cover 13, there is also a lifting unit 5 for driving the sliding sleeve 34 to move along the axial direction of the main shaft 31. An adjusting unit is installed on the sliding sleeve 34. The adjusting unit is used to convert the linear movement of the sliding sleeve 34 along the axial direction of the main shaft 31 into the linear movement of each auxiliary scraper 33 along the radial direction of the main shaft 31. And when the sliding sleeve 34 moves to the lower limit position, the adjusting unit will drive each of the auxiliary scrapers 33 to be in contact with the inner wall of the reactor inner tank 12 synchronously.

[0028] In the embodiment of the present invention, during use, the raw materials are put into the reactor inner tank 12 from the feed pipe 15. Then, the heat-conducting medium is conveyed between the housing 1 and the reactor inner tank 12 through the liquid inlet pipe 14, so as to heat the raw materials in the reactor inner tank 12. Then, the driving unit 2 is started. The driving unit 2 can drive the main shaft 31 to rotate, thereby driving the stirring rods 32 and the auxiliary scrapers 33 to rotate around the main shaft 31 as the rotation center to stir the raw materials. At the same time, the lifting unit 5 drives the sliding sleeve 34 to linearly move along the axial direction of the main shaft 31. The sliding sleeve 34 drives each auxiliary scraper 33 to linearly move along the radial direction of the main shaft 31 through the adjusting unit, thereby improving the stirring effect on the raw materials. After the processing is completed, the sliding sleeve 34 can be controlled to move to the lower limit position. At this time, the adjusting unit will drive each of the auxiliary scrapers 33 to be in contact with the inner wall of the reactor inner tank 12 synchronously. As the main shaft 31 continues to rotate, the inner wall of the reactor inner tank 12 can be scraped and cleaned through the auxiliary scrapers 33, reducing the difficulty of subsequent cleaning treatment.

[0029] Such as Figure 2 、 Figure 4 And Figure 7As shown, as a preferred embodiment of the present invention, a partition layer 11 is further provided between the outer shell 1 and the reactor inner liner 12, which is used to separate the space between the outer shell 1 and the reactor inner liner 12 into two nested cavities. The liquid inlet pipe 14 penetrates through the side wall of the partition layer 11 and extends into the cavity between the partition layer 11 and the reactor inner liner 12. A liquid discharge hole 111 is further provided in the upper part of the side wall of the partition layer 11.

[0030] In the embodiment of the present invention, during use, the heat transfer medium is directly input into the cavity between the partition layer 11 and the reactor inner liner 12 through the liquid inlet pipe 14 to directly heat the reactor inner liner 12. The heat transfer medium after heat exchange flows into the chamber between the outer shell 1 and the partition layer 11 through the liquid discharge hole 111 above the side wall of the partition layer 11, which can play a heat preservation role, so that the heat of the heat transfer medium between the partition layer 11 and the reactor inner liner 12 is transferred to the partition layer 11 as much as possible, improving the utilization rate of heat.

[0031] As Figure 2 and Figure 4 shown, as a preferred embodiment of the present invention, an auxiliary stirring unit 4 for stirring the heat transfer medium between the partition layer 11 and the reactor inner liner 12 is further provided on the inner side of the bottom wall of the partition layer 11. Through the auxiliary stirring unit 4, the temperature of the heat transfer medium between the partition layer 11 and the reactor inner liner 12 can be kept uniform everywhere, improving the heating effect on the partition layer 11.

[0032] In the embodiment of the present invention, the auxiliary stirring unit 4 includes a mounting shaft 41 mounted on the inner side of the bottom wall of the partition layer 11. A magnetic stirring rod 42 is rotatably mounted on the mounting shaft 41. A permanent magnet 43 is mounted at the bottom of each of the stirring rods 32 at the bottommost position, and the N poles and S poles of two adjacent permanent magnets 43 are mounted in opposite positions.

[0033] During use, as the main shaft 31 drives each auxiliary scraper 33 to rotate, the auxiliary scraper 33 can drive the permanent magnet 43 to rotate synchronously, thereby generating a rotating alternating magnetic field, which can drive the magnetic stirring rod 42 to rotate around the permanent magnet 43, so as to stir and mix the heat transfer medium between the partition layer 11 and the reactor inner liner 12, making the temperature of the heat transfer medium everywhere more uniform and improving the heating effect.

[0034] As Figure 1 and Figure 2 shown, as a preferred embodiment of the present invention, the driving unit 2 includes a mounting frame 21 mounted on the top cover 13. A driving motor 22 is mounted on the mounting frame 21. The output end of the driving motor 22 is connected to a driving shaft 23, and the bottom of the driving shaft 23 is connected to the main shaft 31.

[0035] In the embodiment of the present invention, during use, only need to start the drive motor 22, the drive motor 22 can drive the drive shaft 23 to rotate, thereby driving the main shaft 31 to rotate synchronously, and then the raw materials in the reactor inner tank 12 can be stirred and mixed.

[0036] As Figure 1 , Figure 2 and Figure 5 shown, as a preferred embodiment of the present invention, the lifting unit 5 includes a controllable telescopic member 51 installed on the top cover 13, the telescopic end of the controllable telescopic member 51 is connected with a connecting rod 52, and the top end of the sliding sleeve 34 is rotatably installed on the connecting rod 52.

[0037] In the embodiment of the present invention, the controllable telescopic member 51 can be a conventional telescopic control element, specifically it can be an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod. During specific use, the controllable telescopic member 51 is arranged along the axial direction of the drive shaft 23. Only need to control the controllable telescopic member 51 to expand and contract, and then the sliding sleeve 34 can be driven by the connecting rod 52 to move synchronously along the axial direction of the main shaft 31 (the drive shaft 23 and the main shaft 31 are coaxial).

[0038] As Figure 3 , Figure 5 and Figure 6 shown, as a preferred embodiment of the present invention, the adjusting unit includes a connecting column 36 installed at the bottom of the sliding sleeve 34, a plurality of adjusting connecting rods 37 are annularly installed on the connecting column 36, and the number of the adjusting connecting rods 37 is the same as the number of the auxiliary scraping plates 33. One end of each adjusting connecting rod 37 is hinged to the side wall of the sliding sleeve 34, and the other ends of the adjusting connecting rods 37 are respectively hinged to an auxiliary scraping plate 33.

[0039] In the embodiment of the present invention, during use, the sliding sleeve 34 can drive the connecting column 36 to move downward synchronously, the connecting column 36 can drive the adjusting connecting rods 37 to move synchronously, and then each auxiliary scraping plate 33 can be pushed by the adjusting connecting rods 37 to slide synchronously along the corresponding stirring rod 32 (i.e., the radial direction of the main shaft 31). Thus, on the basis of rotating around the main shaft 31 as the rotation center, the auxiliary scraping plates 33 can also perform linear sliding synchronously, thereby improving the mixing effect of the raw materials. And when the sliding sleeve 34 moves to the lower limit position, the adjusting connecting rods 37 will push each auxiliary scraping plate 33 to abut against the inner wall of the reactor inner tank 12. At this time, with the rotation of the main shaft 31, the inner wall of the reactor inner tank 12 can be scraped and cleaned by the auxiliary scraping plates 33, reducing the difficulty of later cleaning treatment.

[0040] As Figure 3 , Figure 5 and Figure 6As shown, as a preferred embodiment of the present invention, the adjusting unit further includes auxiliary cross bars 35 annularly installed on the sliding sleeve 34, and the number of the auxiliary cross bars 35 is the same as that of the auxiliary scraping plates 33. Each of the auxiliary cross bars 35 respectively passes through one of the auxiliary scraping plates 33, and a limiting sliding groove 331 for the auxiliary cross bar 35 to slide in the vertical direction is formed on each of the auxiliary scraping plates 33. A plurality of thorn cones 351 are arranged at the bottom of each of the auxiliary cross bars 35.

[0041] In the embodiment of the present invention, during use, since the auxiliary cross bar 35 can only slide along the limiting sliding groove 331, therefore, during the rotation of the auxiliary scraping plate 33, the auxiliary cross bar 35 will be driven to rotate synchronously, so that the sliding sleeve 34 can rotate synchronously, and there is no need to provide a sliding key structure between the sliding sleeve 34 and the main shaft 31, which simplifies the connection between components. At the same time, during the downward movement of the sliding sleeve 34, the auxiliary cross bar 35 will move downward synchronously, and the auxiliary cross bar 35 can drive the thorn cones 351 to move downward synchronously, so as to pierce the foam at the liquid surface of the raw material through the thorn cones 351, thereby effectively reducing the bubbles generated during the mixing of the raw materials and further improving the mixing effect of the raw materials.

[0042] As Figure 1 shown, as a preferred embodiment of the present invention, it further includes an equipment support 18, and the equipment support 18 is installed on the housing 1.

[0043] As Figure 1 shown, as a preferred embodiment of the present invention, a handle 17 is further provided on the top cover 13, which is convenient for the operator to hold and facilitates the installation and disassembly of the equipment.

[0044] Working principle: During use, the raw materials are put into the inner tank 12 of the reactor from the feed pipe 15. Then, a heat-conducting medium is transported into the cavity between the interlayer 11 and the inner tank 12 of the reactor through the liquid inlet pipe 14 to directly heat the inner tank 12 of the reactor. The heat-exchanged heat-conducting medium flows into the cavity between the outer shell 1 and the interlayer 11 through the drain hole 111 above the side wall of the interlayer 11, which can play a heat preservation role, enabling the heat of the heat-conducting medium between the interlayer 11 and the inner tank 12 of the reactor to be transferred to the interlayer 11 as much as possible. Then, start the driving motor 22. The driving motor 22 can drive the driving shaft 23 to rotate. The driving shaft 23 can drive the main shaft 31 to rotate synchronously, thereby driving the stirring rod 32 and the auxiliary scraper 33 to rotate around the main shaft 31 as the rotation center to stir the raw materials. At the same time, control the controllable telescopic member 51 to expand and contract, and the connecting rod 52 can drive the sliding sleeve 34 to move synchronously along the axial direction of the main shaft 31. The sliding sleeve 34 can drive the connecting column 36 to move downward synchronously. The connecting column 36 can drive the adjusting link 37 to move synchronously, so as to push each auxiliary scraper 33 to slide synchronously along the corresponding stirring rod 32 (i.e., the radial direction of the main shaft 31) through the adjusting link 37. As a result, the auxiliary scraper 33 can not only rotate around the main shaft 31 as the rotation center, but also slide linearly synchronously, thereby improving the mixing effect of the raw materials. During the downward movement of the sliding sleeve 34, the auxiliary cross bar 35 will move downward synchronously. The auxiliary cross bar 35 can drive the thorn cone 351 to move downward synchronously, so as to pierce the foam at the liquid level of the raw materials through the thorn cone 351, effectively reducing the bubbles generated during the mixing process of the raw materials and further improving the mixing effect of the raw materials. After the processing is completed, the sliding sleeve 34 can be controlled to move to the lower limit position. The adjusting link 37 will push each auxiliary scraper 33 to abut against the inner wall of the inner tank 12 of the reactor. At this time, with the rotation of the main shaft 31, the inner wall of the inner tank 12 of the reactor can be scraped and cleaned through the auxiliary scraper 33, reducing the difficulty of later cleaning treatment.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
