It is widely used for mechanical bonding and sealing in various household appliances, circuit boards, electronic components, and other applications. Silicone sealant production reactors are key equipment for synthesizing, mixing, and reacting silicone sealant raw materials. They are widely used in the chemical, electronics, construction, and automotive industries.

[0003] Existing reactors often use fixed stirring blades to mix the raw materials for silicone sealant. This structure often takes a long time to evenly mix the various ingredients, hindering production. Furthermore, due to the stringent temperature requirements during silicone sealant production, maintaining consistent temperatures throughout the reactor when using a heat exchange medium to heat the reactor is crucial.

[0006] The driving mechanism that the said cam is in step with the said cam face is hinged on the said cam face, is fixed with the said cam face, and is provided with the said cam face that is fixed with the said cam face, and is fixed with the said cam face on the driving mechanism, and the said cam face is hinged on the said cam face, is fixed with the said cam face on the said cam face.

[0007] A further technical solution is that a partition is provided between the outer shell and the reactor inner liner, which is used to separate the outer shell and the reactor inner liner into two mutually nested cavities, and the liquid inlet pipe passes through the side wall of the partition and extends into the cavity between the partition and the reactor inner liner, and a drainage hole is also provided on the upper part of the side wall of the partition.

[0008] According to a further technical solution, an auxiliary stirring unit for stirring the heat-conducting medium between the partition and the inner container of the reactor is further provided on the inner side of the bottom wall of the partition.

[0009] A further technical solution is that the auxiliary stirring unit includes a mounting shaft installed on the inner side of the bottom wall of the partition, and a magnetic stirring rod is rotatably installed on the mounting shaft. A permanent magnet is installed at the bottom of each stirring rod located at the bottom, and the N pole and S pole of two adjacent permanent magnets are installed in opposite positions.

[0010] According to a further technical solution, the driving unit includes a mounting bracket mounted on the top cover, a driving motor is mounted on the mounting bracket, an output end of the driving motor is connected to a driving shaft, and a bottom of the driving shaft is connected to the main shaft.

[0011] According to a further technical solution, the lifting unit includes a controllable telescopic member installed on the top cover, the telescopic end of the controllable telescopic member is connected to a connecting rod, and the top end of the sliding sleeve is rotatably installed on the connecting rod.

[0012] According to a further technical solution, the controllable telescopic member is an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod.

Then, a heat-conducting medium is transported to the cavity between the partition and the reactor liner through the liquid inlet pipe to directly heat the reactor liner. The heat-conducting medium after heat exchange flows into the cavity between the outer shell and the partition through the drainage hole above the side wall of the partition, which can play a role in heat preservation, so that the heat of the heat-conducting medium between the partition and the reactor liner is transferred to the partition as much as possible. Then start the drive motor, the drive motor can drive the drive shaft to rotate, and the drive shaft can drive the main shaft to rotate synchronously, thereby driving the stirring rod and the auxiliary scraper to rotate with the main shaft as the rotation center to stir the raw materials. Simultaneously, controlling the controllable telescopic element to extend and retract simultaneously drives the sliding sleeve along the axial direction of the main shaft via the connecting rod. The sliding sleeve drives the connecting post to move downward synchronously, which in turn drives the adjusting connecting rod to move synchronously. This, in turn, propels each auxiliary scraper to slide synchronously along its corresponding stirring rod (i.e., radially of the main shaft). This allows the auxiliary scrapers to not only rotate about the main shaft but also slide linearly, thereby enhancing the mixing effect of the raw materials. As the sliding sleeve moves downward, the auxiliary crossbar moves synchronously downward, driving the spikes downward, thereby puncturing the foam at the raw material surface. After processing is completed, the sliding sleeve can be controlled to move to its lower limit position, where the adjusting connecting rod pushes each auxiliary scraper into contact with the inner wall of the reactor liner. At this point, as the main shaft rotates, the auxiliary scrapers scrape and clean the inner wall of the reactor liner. The device has a simple structure and can integrate multiple working modes, realizing multiple functions of stirring, removing bubbles and cleaning, effectively improving the production efficiency of silicone sealant, and has high working efficiency and good use effect.

DETAILED DESCRIPTION

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

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7As shown, a silicone sealant production reactor provided by one embodiment of the present invention includes a shell 1, a reactor liner 12 is provided inside the shell 1, a connecting flange 121 is provided on the top of the reactor liner 12, and a top cover 13 is detachably mounted on the connecting flange 121. A heat-conducting medium for heating the reactor liner 12 is contained in the cavity between the shell 1 and the reactor liner 12. A liquid inlet pipe 14 is provided on the side wall of the shell 1, and a liquid drain pipe 16 is installed at the bottom of the shell 1. The following also includes:

[0027] The working module 3 includes a main shaft 31 arranged in the inner tank 12 of the reactor, and the top cover 13 is also provided with a driving unit 2 for driving the main shaft 31 to rotate. A plurality of stirring rods 32 are arranged in a ring on the main shaft 31. An auxiliary scraper 33 is connected between each stirring rod 32 located in the same vertical direction, and the auxiliary scraper 33 is installed on the stirring rod 32 along the radial direction of the main shaft 31. A sliding sleeve 34 is also provided on the upper end of the main shaft 31. The sliding sleeve 34 is arranged along the main shaft 31. The top cover 13 is axially slidably mounted on the main shaft 31, and a lifting unit 5 is provided on the top cover 13 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, and the adjusting unit is used to convert the linear motion of the sliding sleeve 34 along the axial direction of the main shaft 31 into the linear motion of each auxiliary scraper 33 along the radial direction of the main shaft 31. When the sliding sleeve 34 moves to the lower limit position, the adjusting unit drives each auxiliary scraper 33 to synchronously abut against the inner wall of the reactor liner 12.

[0028] In this embodiment of the present invention, raw materials are fed into the reactor liner 12 through the feed pipe 15. A heat-conducting medium is then delivered between the outer shell 1 and the reactor liner 12 via the liquid inlet pipe 14, thereby heating the raw materials within the reactor liner 12. The drive unit 2 is then activated, driving the main shaft 31 to rotate, thereby driving the stirring rod 32 and auxiliary scrapers 33 to rotate about the main shaft 31, thereby stirring the raw materials. Simultaneously, the lifting unit 5 drives the sliding sleeve 34 to move linearly along the axial direction of the main shaft 31. The sliding sleeve 34, through the adjustment unit, drives the auxiliary scrapers 33 to move linearly along the radial direction of the main shaft 31, thereby enhancing the stirring effect of the raw materials. After processing is completed, the sliding sleeve 34 is controlled to move to its lower limit position. At this point, the adjustment unit drives the auxiliary scrapers 33 to synchronously contact the inner wall of the reactor liner 12. As the main shaft 31 continues to rotate, the auxiliary scrapers 33 scrape and clean the inner wall of the reactor liner 12, reducing the difficulty of subsequent cleaning.

[0029] like Figure 2 、 Figure 4 and Figure 7As shown, as a preferred embodiment of the present invention, a partition 11 is further provided between the outer shell 1 and the reactor liner 12, which is used to separate the outer shell 1 and the reactor liner 12 into two mutually nested cavities, and the liquid inlet pipe 14 passes through the side wall of the partition 11 and extends into the cavity between the partition 11 and the reactor liner 12, and a drainage hole 111 is also provided on the upper part of the side wall of the partition 11.

[0030] In this embodiment of the present invention, during use, the heat transfer medium is directly introduced into the cavity between the barrier 11 and the reactor liner 12 through the liquid inlet pipe 14, directly heating the reactor liner 12. After heat exchange, the heat transfer medium flows into the cavity between the outer shell 1 and the barrier 11 through the drainage hole 111 above the side wall of the barrier 11, which can play a role in heat preservation. The heat of the heat transfer medium between the barrier 11 and the reactor liner 12 is transferred to the barrier 11 as much as possible, thereby improving the utilization rate of heat.

[0031] like Figure 2 and Figure 4 As shown, as a preferred embodiment of the present invention, an auxiliary stirring unit 4 for stirring the heat-conducting medium between the partition 11 and the reactor liner 12 is further provided on the inner side of the bottom wall of the partition 11. The auxiliary stirring unit 4 can keep the temperature of the heat-conducting medium between the partition 11 and the reactor liner 12 uniform and consistent, thereby improving the heating effect of the partition 11.

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

[0033] During use, as the main shaft 31 drives the auxiliary scrapers 33 to rotate, the auxiliary scrapers 33 can drive the permanent magnets 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, thereby stirring and mixing the heat-conducting medium between the partition 11 and the reactor liner 12, making the temperature of the heat-conducting medium more uniform everywhere, and improving the heating effect.

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

[0035] In the embodiment of the present invention, when in use, it is only necessary to start the drive motor 22, which can drive the drive shaft 23 to rotate, thereby driving the main shaft 31 to rotate synchronously, and the raw materials in the reactor liner 12 can be stirred and mixed.

[0036] like Figure 1 、 Figure 2 and Figure 5 As 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 to a connecting rod 52, and the top end of the sliding sleeve 34 is rotatably installed on the connecting rod 52.

[0037] In this embodiment of the present invention, the controllable telescopic member 51 can be a conventional telescopic control element, specifically an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod. During use, the controllable telescopic member 51 is positioned axially along the drive shaft 23. Simply controlling the controllable telescopic member 51 to extend or retract causes the connecting rod 52 to drive the sliding sleeve 34 to move synchronously along the axial direction of the main shaft 31 (the drive shaft 23 and the main shaft 31 are coaxial).

[0038] like Figure 3 、 Figure 5 and Figure 6 As shown, as a preferred embodiment of the present invention, the adjustment unit includes a connecting column 36 installed at the bottom of the sliding sleeve 34, and a plurality of adjustment links 37 are installed in a circle on the connecting column 36, and the number of the adjustment links 37 is the same as the number of the auxiliary scrapers 33. One end of the adjustment link 37 is hinged to the side wall of the sliding sleeve 34, and the other end of each adjustment link 37 is hinged to a corresponding auxiliary scraper 33.

[0039] In this embodiment of the present invention, during use, the sliding sleeve 34 can drive the connecting post 36 to move downward synchronously, and the connecting post 36 can drive the adjusting link 37 to move synchronously. As a result, the adjusting link 37 pushes each auxiliary scraper 33 to slide synchronously along the corresponding stirring rod 32 (i.e., radially of the main shaft 31). This allows the auxiliary scrapers 33 to rotate about the main shaft 31 while also performing linear sliding, thereby improving the mixing effect of the raw materials. Furthermore, when the sliding sleeve 34 moves to the lower limit position, the adjusting link 37 pushes each auxiliary scraper 33 into contact with the inner wall of the reactor liner 12. At this point, as the main shaft 31 rotates, the auxiliary scrapers 33 can scrape and clean the inner wall of the reactor liner 12, reducing the difficulty of subsequent cleaning.

[0040] like Figure 3 、 Figure 5 and Figure 6As shown, as a preferred embodiment of the present invention, the adjustment unit also includes auxiliary cross bars 35 installed in a ring on the sliding sleeve 34, and the number of the auxiliary cross bars 35 is the same as the number of the auxiliary scrapers 33. Each of the auxiliary cross bars 35 passes through one of the auxiliary scrapers 33 respectively, and each of the auxiliary scrapers 33 is provided with a limiting groove 331 for the auxiliary cross bar 35 to slide in the vertical direction, and a plurality of spikes 351 are provided at the bottom of each of the auxiliary cross bars 35.

[0041] In the embodiment of the present invention, during use, since the auxiliary crossbar 35 can only slide along the limiting chute 331, the auxiliary scraper 33 will drive the auxiliary crossbar 35 to rotate synchronously during its rotation, thereby allowing the sliding sleeve 34 to rotate synchronously without the need for a sliding key structure between the sliding sleeve 34 and the main shaft 31, simplifying the connection between the components. At the same time, as the sliding sleeve 34 moves downward, the auxiliary crossbar 35 will move downward synchronously, and the auxiliary crossbar 35 can drive the spike 351 to move downward synchronously, thereby puncturing the foam at the liquid surface of the raw material through the spike 351, thereby effectively reducing bubbles generated during the raw material mixing process and further improving the raw material mixing effect.

[0042] like Figure 1 As shown, as a preferred embodiment of the present invention, it also includes a device bracket 18, and the device bracket 18 is used to install the housing 1.

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

[0044] Working principle: When in use, the raw materials are put into the reactor liner 12 from the feed pipe 15. Then the heat-conducting medium is transported to the cavity between the partition 11 and the reactor liner 12 through the liquid inlet pipe 14 to directly heat the reactor liner 12. The heat-conducting medium after heat exchange flows into the cavity between the outer shell 1 and the partition 11 through the drainage hole 111 above the side wall of the partition 11, which can play a role in heat preservation, so that the heat of the heat-conducting medium between the partition 11 and the reactor liner 12 is transferred to the partition 11 as much as possible. Then start the drive motor 22, the drive motor 22 can drive the drive shaft 23 to rotate, and the drive shaft 23 can drive the main shaft 31 to rotate synchronously, thereby driving the stirring rod 32 and the auxiliary scraper 33 to rotate with the main shaft 31 as the rotation center to stir the raw materials. At the same time, controlling the controllable telescopic member 51 to extend and retract simultaneously drives the sliding sleeve 34 along the axial direction of the main shaft 31 via the connecting rod 52. The sliding sleeve 34 drives the connecting column 36 to move downward synchronously, and the connecting column 36 drives the adjustment link 37 to move synchronously. The adjustment link 37 then pushes each auxiliary scraper 33 to slide synchronously along the corresponding stirring rod 32 (i.e., radially of the main shaft 31). This allows the auxiliary scrapers 33 to rotate about the main shaft 31 while also performing linear sliding, thereby improving the mixing effect of the raw materials. As the sliding sleeve 34 moves downward, the auxiliary crossbar 35 also moves downward synchronously, driving the spike 351 to move downward synchronously. The spike 351 punctures the foam at the liquid surface of the raw materials, effectively reducing bubbles generated during the mixing process and further improving the mixing effect. After the processing is completed, the sliding sleeve 34 can be controlled to move to the lower limit position, and the adjusting connecting rod 37 will push each auxiliary scraper 33 to abut against the inner wall of the reactor liner 12. At this time, as the main shaft 31 rotates, the auxiliary scraper 33 can be used to scrape and clean the inner wall of the reactor liner 12, reducing the difficulty of subsequent cleaning processing.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
