Description

Technical Field

[0001] This utility model relates to the field of silicone oil production technology, specifically a mixing device for silicone oil production. Background Technology

[0002] The mixing device for silicone oil production is used to mix various raw materials in the silicone oil production process. Silicone oil has excellent chemical stability and high temperature resistance. It is colorless and odorless, and has high temperature stability and chemical stability. Silicone oil is a non-polar compound that is insoluble in water, but can be miscible with many organic solvents. It has the characteristics of low viscosity, low surface tension and high flash point, and remains stable over a wide temperature range.

[0003] Patent CN208809911U discloses a high-efficiency silicone oil mixing device, including a mixing tank, a mixing motor, and a feed port. A heater is connected to the side of the jacket via a heat transfer pipe. A spiral mixing blade is fixedly welded onto the mixing shaft. A scraper with the same curvature as the inner wall of the mixing tank is provided around the spiral mixing blades. A discharge pipe is provided at the bottom of the mixing tank, and a rotating mixing drum is fixedly installed inside the mixing tank at the end of the mixing shaft, corresponding to the input end of the discharge pipe. This high-efficiency silicone oil mixing device has the advantages of preheating the silicone oil raw materials before mixing, improving the efficiency of silicone oil mixing, and effectively scraping off and discharging the silicone oil adhering to the inner wall of the mixing container, facilitating cleaning of the mixing container. It solves the problems of silicone oil easily adhering to the inner wall of the mixing container and being difficult to discharge, as well as the low mixing efficiency of existing silicone oil mixing methods.

[0004] The above-mentioned device has certain shortcomings when in use: it can produce a uniform mixture of silicone oil by spiral stirring inside the mixing tank with a spiral stirring blade, but the overall uniformity of the material mixing is poor due to the stirring in one direction by a single spiral stirring blade in the mixing tank.

[0005] Therefore, this utility model provides a mixing device for silicone oil production to solve the above problems. Utility Model Content

[0015] Through the above technical solution, the hot air can be delivered to the transmission rod, connecting seat, C-shaped frame and stirring blade through the cooperation of the conveying pipe and the double-pass pipe, and discharged from the air outlet.

[0016] As a further optimization, a fixing ring is fixedly installed at the bottom of the outer wall of the mixing cylinder, and a support frame is fixedly installed on the bottom wall of the fixing ring.

A gear 63 is fixedly mounted on the top of the transmission rod 67 on the left side, passing through the mixing cylinder 3 via a bearing. A gear 64 is fixedly mounted on the top of the transmission rod 67 on the right side, passing through the mixing cylinder 3 via a bearing. Gear 62... The transmission ratio of gear 2 63 and gear 3 64 is 3:2:1. Connecting seats 65 are fixedly installed on the top and bottom of the outer wall of the two transmission rods 67. C-shaped frames 68 are fixedly installed on the outer wall of the connecting seats 65 on the same side. Stirring blades 69 are fixedly installed on the outer wall of several C-shaped frames 68. Several air outlets 610 are evenly opened on the bottom of the outer wall of the stirring blades 69. The transmission rods 67, connecting seats 65, C-shaped frames 68 and stirring blades 69 are all hollow inside. Gear 1 62, gear 2 63 and gear 3 are all located inside the protective cover 13.

[0034] In this embodiment of the present invention, the purpose of this arrangement is that the mixing component 6, by means of differential reverse rotation, causes the stirring blades 69 distributed on the left and right sides to rotate in opposite directions, thereby uniformly mixing the raw materials inside the mixing cylinder 3 and improving the mixing uniformity of silicone oil and raw materials.

[0035] Example 2:

[0036] like Figures 1 to 5 As shown, this embodiment provides a technical solution based on embodiment 1: the heating component 7 includes a fan 71, which is fixedly connected to the top wall of the protective cover 13. The air inlet of the fan 71 is connected to the outside, and the air outlet of the fan 71 is connected to an air outlet pipe 72. The rear end of the air outlet pipe 72 is connected to a heating box 73. The bottom wall of the heating box 73 is fixedly connected to the top wall of the protective cover 13. A plurality of electric heating tubes 74 are evenly installed on the inner wall of the heating box 73. The electric heating tubes 74 are electrically connected to an external electric heating module. The front wall of the heating box 73 is connected to a conveying pipe 75. 5. A double-pipe 76 is connected to the front end. The bottom end of the double-pipe 76 is connected to the top end of the transmission rod 67 through the anti-leakage bearing through the protective cover 13. A fixing ring 1 is fixedly installed at the bottom of the outer wall of the mixing cylinder 3. A support frame 2 is fixedly installed on the bottom wall of the fixing ring 1. A discharge pipe 4 is connected to the bottom end of the mixing cylinder 3. A control valve 5 is installed on the outer wall of the discharge pipe 4. A liquid level window 12 is installed on the front wall of the mixing cylinder 3. An exhaust pipe 8 is installed on the outer wall of the mixing cylinder 3. An exhaust valve 9 is installed on the outer wall of the exhaust pipe 8. A feed pipe 10 is installed on the outer wall of the mixing cylinder 3. A feed valve 11 is installed on the outer wall of the feed pipe 10.

[0037] In this embodiment of the utility model, the purpose of this arrangement is that the heating component 7 heats the cool air inside the heating box 73 through the electric heating tube 74 and then delivers it to the transmission rod 67, connecting seat 65, C-shaped frame 68 and stirring blade 69, and discharges it into the silicone oil through the air outlet 610. This can heat the silicone oil raw material, and the hot air entering the silicone oil will surge upward, which can also improve the mixing uniformity of the silicone oil raw material.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] During operation, the control valve 5, drive motor 61, fan 71, external heating module, exhaust valve 9, and feed valve 11 are electrically connected via an external power supply and controller. First, the feed valve 11 is opened, and silicone oil raw material is added into the fixed ring 1 through the feed pipe 10. The fan 71 sends air into the heating chamber 73 through the air outlet pipe 72. The external controller controls the external heating module to start the heating element 74, heating the air entering the heating chamber 73. The hot air passes through the conveying pipe 75 and then into the double-pass pipe 76 and transmission rod 67. After passing through the hollow areas inside the connecting seat 65, C-shaped frame 68, and stirring blade 69, the hot air is discharged from the air outlet 610 into the silicone oil for further heating. Simultaneously, the drive motor 61 is started, driving gear 62 to rotate. When gear 62 rotates, it drives gears 63 and 64 to rotate. When gears 63 and 64 rotate, they drive transmission rod 67 and connecting seat 65 to rotate. When connecting seat 65 rotates, it drives C-shaped frame 68 and stirring blade 69 to stir the silicone oil. Through differential rotation, the transmission rod 67 on the left and the transmission rod 67 on the right rotate at different speeds. As a result, the stirring blade 69 mixes the silicone oil in the mixing cylinder 3 more evenly. At the same time, the hot air discharged from the vent 610 will continue to heat the silicone oil and churn from bottom to top to improve the mixing effect. By opening the exhaust valve 9, the hot air inside the mixing cylinder 3 can be discharged to the outside through the exhaust pipe 8, and the liquid level change inside the fixed ring 1 can be observed in real time through the liquid level window 12.
