Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of silicone oil dehydration kettle equipment, and in particular to a dehydration kettle device for methyl hydrogen silicone oil. Background Technology
[0002] In the production process of silicone oil, hydrogen-containing silicone oil, DMC, and MM are first added to a reactor, followed by the addition of 98% sulfuric acid. The high concentration of sulfuric acid absorbs water to dehydrate the high-hydrogen-content silicone oil. A mechanical paddle agitator is installed inside the reactor to accelerate mixing. However, in actual production, concentrated sulfuric acid is usually added at the top of the reactor. Due to the difference in density, concentrated sulfuric acid and silicone oil are prone to stratification. Although the agitator can mix them, the rotation of the agitator blades mainly involves horizontal mixing, resulting in uneven vertical distribution of concentrated sulfuric acid and hydrogen-containing silicone oil, and insufficient contact. This leads to a long dehydration time in the reactor, requiring further improvement. Utility Model Content
[0003] The purpose of this invention is to provide a dehydration reactor for methyl hydrogen silicone oil to solve the technical problem of low dehydration efficiency in the existing hydrogen silicone oil dehydration process.
[0004] The utility model relates to a dehydration reactor device for methyl hydrogen silicone oil, comprising a reactor body, an inlet pipe and an outlet pipe respectively installed at the top and bottom of the reactor body, and a vertically arranged feeding pipe rotatably connected to the reactor body and drivingly connected to a drive assembly. Several inclined tubes are connected downwards along the circumferential direction at the bottom of the feeding tube, and the inclined tubes are located inside the reactor body. A vertically sealed vertical tube is connected downwards at the bottom of the inclined tubes. Several outlet cone holes are horizontally formed on the outer side of the vertical tubes, and an elastic centrifugal plug assembly is installed in each outlet cone hole.
[0005] Furthermore, the elastic centrifugal plug assembly includes a cone plug located inside the liquid outlet cone hole. A connecting rod is screwed to the inner end of the cone plug, and a limiting plate is fixedly connected to the other end of the connecting rod. A compression spring is fitted on the connecting rod, and the two ends of the compression spring contact the limiting plate and the inner wall of the vertical tube, respectively.
[0006] Furthermore, a process hole coaxial with the liquid outlet cone hole is horizontally opened on the inner side of the vertical pipe, and a sealing plug is screwed into the process hole. The diameter of the process hole is larger than the diameter of the limiting plate.
[0007] Furthermore, the drive assembly includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly mounted on the feeding pipe and located outside the reactor body. The first bevel gear meshes with the second bevel gear. The second bevel gear is fixedly mounted on a drive shaft. The drive shaft is rotatably connected to a bearing seat and is connected to a motor for transmission.
[0008] Furthermore, a feeding hopper is installed at the top of the feeding pipe.
[0009] The beneficial effects of this utility model are as follows: This utility model has a simple structure. It is designed with a discharge pipe that has both stirring and dispersing gradient liquid addition functions in the dehydration kettle. An elastic centrifugal plug assembly is designed on the discharge pipe. When the vertical pipe rotates at high speed, the centrifugal force causes the elastic centrifugal plug assembly to open and release concentrated sulfuric acid liquid, so that the concentrated sulfuric acid and the hydrogen-containing silicone oil can be fully mixed and contacted in both the horizontal and vertical directions, thereby improving the dehydration efficiency of the hydrogen-containing silicone oil.

[0015] like Figures 1 to 4 As shown, a dehydration reactor for methyl hydrogen silicone oil includes a reactor body 1. An inlet pipe 2 and an outlet pipe 3 are respectively installed at the top and bottom of the reactor body 1. It also includes a vertically arranged feeding pipe 4, which is rotatably connected to the reactor body 1 and is driven by a drive assembly. Several inclined tubes are connected downwards along the circumferential direction at the bottom of the feeding pipe 4. The inclined tubes are located inside the reactor body 1. A vertically downward-facing vertical tube 5 with a sealed bottom end is connected at the bottom of the inclined tubes. Several liquid outlet cone holes 9 are horizontally opened on the outside of the vertical tube 5. An elastic centrifugal plug assembly is installed in the liquid outlet cone hole 9. It is worth noting that all components of this application can be made of rigid resin.
[0016] like Figure 4 As shown, the elastic centrifuge plug assembly includes a cone plug 10 located inside the outlet cone hole 9. A connecting rod 12 is screwed to the inner end of the cone plug 10, and a limiting disk 13 is fixedly connected to the other end of the connecting rod 12. A compression spring 11 is fitted on the connecting rod 12, and the two ends of the compression spring 11 are in contact with the limiting disk 13 and the inner wall of the vertical tube 5, respectively. A process hole 14 coaxial with the outlet cone hole 9 is horizontally opened on the inner side of the vertical tube 5. A sealing plug 15 is screwed into the process hole 14, and the diameter of the process hole 14 is larger than the diameter of the limiting disk 13.
[0017] like Figure 1 and Figure 3 As shown, the drive assembly includes a first bevel gear 6 and a second bevel gear 7. The first bevel gear 6 is fixedly mounted on the feeding pipe 4 and is located outside the reactor body 1. The first bevel gear 6 meshes with the second bevel gear 7. The second bevel gear 7 is fixedly mounted on the transmission shaft. The transmission shaft is rotatably connected to the bearing seat and is connected to the motor 8. To facilitate feeding, a feeding hopper 16 is installed at the top of the feeding pipe 4.
[0018] In specific work, such as Figures 1 to 4 As shown, first, hydrogen-containing silicone oil, DMC, and MM are added into the feed pipe 2, and then concentrated sulfuric acid is added into the feed hopper 16. The motor 8 is started to drive the feed pipe 4 and the vertical pipe 5 to rotate at high speed. Due to the centrifugal force, the cone plug 10 is thrown out, thereby discharging the concentrated sulfuric acid from different gradient positions. Through the rotation and stirring of the vertical pipe 5, the concentrated sulfuric acid and the hydrogen-containing silicone oil can be fully mixed and contacted in both the horizontal and vertical directions, thereby improving the dehydration efficiency of the hydrogen-containing silicone oil.
[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
