Description

Technical Field

[0001] This utility model relates to the field of high-temperature stirring tank technology, and in particular to a high-temperature stirring tank for silicone oil production. Background Technology

[0002] Silicone oil, as a chemical material with good chemical stability and high temperature resistance, is commonly used in industrial production. It is often used in industrial products such as lubricants and mold release agents. However, the production of silicone oil often requires the use of a special high-temperature stirring tank. Through high-temperature mixing and polymerization reactions of various raw materials, silicone oil can be produced quickly.

[0003] To address this, patent specification CN221673994U discloses a high-temperature stirred tank for producing high-boiling-point silicone oil, belonging to the field of stirred tank technology. The high-boiling-point silicone oil high-temperature stirred tank includes a high-temperature stirred tank body, an upper cover, a stirring assembly, and a high-temperature heating tube. The upper cover is movably engaged with the upper end of the high-temperature stirred tank body. The stirring assembly is rotatably connected to the high-temperature stirred tank body and includes a main rotating shaft, a stirring mounting base, a stirring inclined plate, an arc-shaped stirring blade, and an inclined stirring blade. This allows the high-boiling-point silicone oil high-temperature stirred tank to fully stir the high-boiling-point silicone oil within the stirred tank during use, preventing uneven stirring due to sedimentation of the high-boiling-point silicone oil. It also facilitates disassembly and cleaning, effectively improving the stirring efficiency of the high-boiling-point silicone oil high-temperature stirred tank. Furthermore, it can uniformly heat the high-boiling-point silicone oil within the stirred tank, thereby effectively improving the quality of the stirred production. While the above-mentioned high-temperature stirred tank has good stirring effects during use, some problems still exist:

[0004] When the aforementioned high-temperature stirred tank is in use, its large internal space and uneven temperature distribution during stirring can affect the production efficiency of silicone oil. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature stirring vessel for silicone oil production, in order to solve the defect of uneven internal temperature distribution in existing high-temperature stirring vessels for silicone oil production.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-temperature stirring kettle for silicone oil production, comprising an inner tank and a driving assembly. A top cover is fixedly connected to the top of the inner tank, and a feed inlet is provided on one side of the top of the top cover. The driving assembly is installed at the middle position of the top of the top cover. An outer tank is sleeved on the lower side of the outer side of the inner tank. A heat-conducting structure is fixedly connected to the middle position of the outer wall of the inner tank. The bottom end of the driving assembly penetrates into the interior of the inner tank and is fixedly connected to the top of a first transmission rod. Stirring blades are fixedly connected to both sides of the first transmission rod. A second transmission rod is provided below the first transmission rod. An auxiliary structure is fixedly connected to the bottom end of the second transmission rod. The auxiliary structure includes a reciprocating screw, a support frame, a connecting rod, a side bevel gear, a transmission gear, an internal threaded sleeve, a bottom plate, a drainage groove, a guide tube, and a drainage pipe. The reciprocating screw is fixedly connected to the bottom end of the second transmission rod.

[0007] When using this high-temperature stirred tank to produce silicone oil, the raw materials are injected into the inner tank through the feed port. When the high-temperature stirred tank is started, heat transfer oil is injected into the inner jacket between the inner and outer tanks, so that the heat of the heat transfer oil is quickly transferred to the inside of the inner tank for heating treatment. At the same time, the drive assembly is started to drive the first transmission rod and the stirring blade to stir the raw materials inside the inner tank.

[0008] Preferably, the heat-conducting structure includes a fixed plate, a heat-conducting extension rod, and heat-absorbing fins. The fixed plate is fixedly connected to the outer wall of the inner tank. A heat-conducting extension rod is fixedly connected to one side of the fixed plate, and heat-absorbing fins are fixedly connected to the other side of the fixed plate. The heat-conducting extension rod extends into the interior of the inner tank to increase the heat conduction range.

[0009] Preferably, the fixing plate is perpendicular to the heat-conducting extension rod, and the heat-absorbing fins are evenly distributed on the other side of the fixing plate to improve heat conduction efficiency.

[0010] Preferably, a support frame is rotatably connected to the lower side of the outer wall of the first transmission rod, and connecting rods are fixedly connected to both sides of the support frame. A side bevel gear is rotatably connected to one side inside the support frame. Transmission gears are fixedly connected to the bottom end of the first transmission rod and the top end of the second transmission rod. An internal threaded sleeve is fitted on the outer side of the reciprocating screw. A base plate is fixedly connected to the bottom end of the internal threaded sleeve. A drainage groove is opened inside the base plate. Guide tubes penetrate both sides inside the base plate. A drainage tube is fixedly connected to the bottom end of the guide tube.

[0011] Preferably, the reciprocating lead screw and the internal threaded sleeve are connected by a thread, and the side bevel gear and the transmission gear are meshed, so that the two sets of stirring blades stir in opposite directions.

[0012] Preferably, a plurality of the diversion channels are provided inside the bottom plate, and the plurality of the diversion channels are distributed at equal intervals inside the bottom plate, so as to enable the bottom plate to perform bottom-up stirring.

[0013] Preferably, the base plate and the guide tube have a sliding structure, and the interior of the drain tube is connected to the interior of the inner tank for secondary heating.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the high-temperature stirring vessel is used, a fixing plate is fixed in the outer wall area of ​​the inner tank inside the outer tank. Heat is quickly conducted through heat-absorbing fins and heat-conducting extension rods, and the heat radiation range is increased. The combination of side bevel gears and transmission gears causes the stirring blades on both sides of the first and second transmission rods to rotate in opposite directions to improve the stirring efficiency. At the same time, the reciprocating screw and the internal threaded sleeve cause the bottom plate to move up and down, thereby stirring the unstirred part at the bottom of the inner tank cavity, so as to make the raw materials and temperature distribution inside the inner tank more uniform.

[0015] 1. When the drive assembly drives the first transmission rod to rotate, the two sets of transmission gears rotate in opposite directions under the indirect transmission of the side bevel gears, so that the first transmission rod and the second transmission rod respectively drive the two sets of stirring blades to rotate in opposite directions and stir.

[0016] At the same time, when the second transmission rod rotates, the internal threaded sleeve connected to the reciprocating lead screw drives the bottom plate to move up and down along the outer wall of the guide tube, and stirs the raw material at the bottom of the inner tank cavity through the diversion groove, so as to make the raw material and temperature distribution inside the inner tank more uniform.

[0017] Furthermore, by installing a corresponding air pump, the hot air inside the inner tank can circulate along the drainage pipe and guide pipe, thereby allowing the guide pipe to reheat the raw materials inside the inner tank.

[0018] 2. When the heat transfer oil is injected into the outer tank, the heat of the heat transfer oil is quickly absorbed by the heat-absorbing fins and transferred to the interior of the inner tank through the heat-conducting extension rod, thereby increasing the heat radiation efficiency of the high-temperature stirring vessel.

[0026] Please see Figures 1-5This utility model provides a high-temperature stirring vessel for silicone oil production, comprising an inner tank 1 and a drive assembly 4. A top cover 2 is fixedly connected to the top of the inner tank 1, and a feed inlet 3 is provided on one side of the top of the top cover 2. The drive assembly 4 is installed at the middle position of the top of the top cover 2. An outer tank 5 is fitted around the lower outer side of the inner tank 1. The bottom end of the drive assembly 4 penetrates into the interior of the inner tank 1 and is fixedly connected to the top of a first transmission rod 6. Stirring blades 7 are fixedly connected to both sides of the first transmission rod 6. A second transmission blade is provided below the first transmission rod 6. The bottom end of the moving rod 8 and the second transmission rod 8 is fixedly connected to an auxiliary structure 10. The auxiliary structure 10 includes a reciprocating lead screw 1001, a support frame 1002, a connecting rod 1003, a side bevel gear 1004, a transmission gear 1005, an internal threaded sleeve 1006, a base plate 1007, a drainage groove 1008, a guide tube 1009, and a drainage tube 1010. The reciprocating lead screw 1001 is fixedly connected to the bottom end of the second transmission rod 8. The support frame 1002 is rotatably connected to the lower part of the outer wall of the first transmission rod 6. Connecting rods 1003 are fixedly connected to both sides of the support frame 1002. A side bevel gear 1004 is rotatably connected to one side inside the support frame 1002.

An internal threaded sleeve 1006 is fitted on the outer side of the reciprocating screw 1001. A base plate 1007 is fixedly connected to the bottom end of the internal threaded sleeve 1006. A drainage groove 1008 is opened inside the base plate 1007. Guide tubes 10 are passed through both sides inside the base plate 1007. 09. A drainage pipe 1010 is fixedly connected to the bottom end of the guide pipe 1009. The reciprocating screw 1001 and the internal threaded sleeve 1006 are threadedly connected. The side bevel gear 1004 and the transmission gear 1005 are meshed. Several drainage grooves 1008 are opened inside the bottom plate 1007, and the several drainage grooves 1008 are evenly distributed inside the bottom plate 1007. The bottom plate 1007 and the guide pipe 1009 are in a sliding structure. The inside of the drainage pipe 1010 is connected to the inside of the inner tank 1.

[0027] See attached document Figure 2 , Figure 4 and Figure 5When the high-temperature stirring vessel is in use, since the bottom end of the first transmission rod 6 and the top end of the second transmission rod 8 both pass through the support frame 1002 and are fixed to the transmission gear 1005, and both sets of transmission gears 1005 mesh with the side bevel gear 1004, when the drive assembly 4 drives the first transmission rod 6 to rotate, the two sets of transmission gears 1005 rotate in opposite directions under the indirect transmission of the side bevel gear 1004. This causes the first transmission rod 6 and the second transmission rod 8 to drive the two sets of stirring blades 7 to rotate in opposite directions for stirring. At the same time, since the bottom end of the second transmission rod 8 is fixed to the reciprocating screw 1001, when the second transmission rod 8 rotates, the reciprocating screw 1001 rotates simultaneously. When the reciprocating screw 1001 is engaged, the internal threaded sleeve 1006 drives the bottom plate 1007 to move up and down along the outer wall of the guide tube 1009, and stirs the raw material at the bottom of the inner tank 1 cavity through the diversion groove 1008, so as to make the raw material and temperature distribution inside the inner tank 1 more uniform. Furthermore, since the guide tube 1009 is connected to the inside of the inner tank 1 through the diversion tube 1010, by installing a corresponding air pump, the hot air inside the inner tank 1 can circulate along the diversion tube 1010 and the guide tube 1009, so that the guide tube 1009 can reheat the raw material inside the inner tank 1, thereby improving the thermal efficiency of the high-temperature stirring vessel.

The fixing plate 901 is perpendicular to the heat-conducting extension rod 902, and the heat-absorbing fins 903 are evenly distributed on the other side of the fixing plate 901.

[0029] See attached document Figure 2 and Figure 3 When the high-temperature stirred tank is in use, heat is transferred to the interior of the inner tank 1 for heating by injecting heat transfer oil into the interior of the outer tank 5 through thermal radiation. In order to improve its heat transfer efficiency, a fixing plate 901 is fixed on the outer wall of the inner tank 1 and a heat transfer extension rod 902 extends into the interior of the inner tank 1. When the heat transfer oil is injected into the interior of the outer tank 5, the heat of the heat transfer oil is quickly absorbed by the heat absorption fins 903 and transferred to the interior of the inner tank 1 through the heat transfer extension rod 902, thereby increasing the heat radiation efficiency of the high-temperature stirred tank.
