[0018] See also Figures 1 to 2 , the utility model provides an embodiment: a silicone thermal conductive potting glue production system, comprising a silicone oil storage tank 1, a kneader 3 connected to the silicone oil storage tank 1, and a cooling tank 7 connected to the kneader 3 at one end away from the silicone oil storage tank 1, a metering pump 2 is provided between the silicone oil storage tank 1 and the kneader 3, an emptying valve 5 is provided on the top of the kneader 3, and a vacuum suction device 4 is provided on the kneader 3, a feeding pump A6 is provided between the kneader 3 and the cooling tank 7, the cooling tank 7 is a cavity structure with an opening at the top and a hollow interior, a plurality of inner coils 8 distributed at equal intervals in the vertical direction are provided in the cavity of the cooling tank 7, and the plurality of inner coils 8 are fixed together, a multi-axis disperser 10 is connected to the end of the cooling tank 7 away from the kneader 3, and a feeding pump B9 is provided between the cooling tank 7 and the multi-axis disperser 10, A circulation ball valve 11 is provided at the top of the multi-axis disperser 10, and a discharge ball valve 12 is provided at the bottom of the multi-axis disperser 10. A filling machine 14 is connected to the end of the multi-axis disperser 10 away from the cooling storage tank 7, and a feed pump C13 is provided between the multi-axis disperser 10 and the filling machine 14. The kneading machine 3 adopts the patent with patent number CN202320829890.1 in the prior art, the vacuum suction device 4 can adopt the patent with application number CN202122911857.7, the multi-axis disperser 10 adopts the patent with patent number CN202222580994.1 in the prior art, and the filling machine 14 adopts the patent with patent number CN202322892028.8 in the prior art. The structures of the kneading machine 3, the vacuum suction device 4, the multi-axis disperser 10 and the filling machine 14 are no longer repeated here.

[0019] Please refer to Figures 1 to 2During the operation of the present invention, the drain valve 5 on the top of the kneader 3 is opened, the metering pump 2 is started to add a specified amount of silicone oil into the kneader 3, the drain valve 5 is closed, the kneader 3 is started to stir the silicone oil, and the vacuum suction device 4 is started to suck the weighed powder into the kneader 3, the appropriate stirring speed and temperature are set, and the interlayer heating is started to heat up. During this process, the vacuum is turned on at an appropriate time to remove the moisture in the slurry; at the beginning of stirring, the current measured by the current transformer will be relatively high. As the stirring proceeds, the powder is gradually dispersed in the silicone oil, and the current will continue to decrease until it tends to remain unchanged for a certain period of time, and the process can be considered to be completed, thereby producing high-temperature slurry; the high-temperature slurry is transferred to the cooling tank 7 using the feed pump A6. , after circulating water is introduced into the inner coil 8 and cooled to a certain temperature, a certain weight of slurry is weighed through the feed pump B9 and sent to the multi-axis disperser 10. Usually, the feed pump B9 corresponds to two multi-axis dispersers 10, and each multi-axis disperser 10 produces two components of the silicone thermal conductive potting glue; during the dispersion process, the multi-axis disperser 10 closes the discharge ball valve 12, opens the circulation ball valve 11 and the feed pump C13, so that the slurry circulates to improve the efficiency of slurry dispersion; when the current transformer value of the multi-axis disperser 10 drops to a certain level and remains unchanged or even begins to show an upward trend, sampling can be carried out for testing. After the test is qualified, the circulation ball valve 11 is closed, the discharge ball valve 12 is opened, and the finished product is transferred to the filling machine 14 for packaging using the feed pump C13.

[0020] The reason for using kneader 3 before multi-shaft disperser 10 is that kneader 3 operates at a low speed, which is suitable for coarse dispersion. This low speed does not damage the powder surface and does not increase product viscosity. It also allows for mixing at a higher powder addition ratio, improving production efficiency. Multi-shaft disperser 10, on the other hand, operates at a high speed, and prolonged dispersion can easily increase product viscosity. It is primarily used for fine powder dispersion and for mixing and evenly diluting small ingredients such as silicone oil, curing agents, catalysts, and color pastes. The slurry must be cooled after mixing in kneader 3, primarily to prevent the ineffectiveness of some subsequently added small ingredients due to high temperatures. Using internal coil 8 for cooling offers the advantages of a large heat exchange area, high heat transfer efficiency, and rapid temperature reduction.

[0021] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
