Description

Technical Field

[0001] This utility model relates to the technical field of high-activity side-hydrogen-containing silicone oil production equipment, specifically a catalytic hydrogenation reactor. Background Technology

[0002] Highly reactive hydrogen-containing silicone oil is an organosilicon material with a special chemical structure and excellent properties. Under the action of a metal catalyst, it can crosslink at appropriate temperatures to form a waterproof film on the surface of various substrates. It is widely used as a waterproofing agent, anti-sticking agent, or anti-corrosion agent for fabrics, paper, metals, leather, wood, glass, cement, ceramics, and marble. In the production of highly reactive hydrogen-containing silicone oil, a reaction vessel is generally used. However, existing reaction vessels typically use hydrogen pipes to deliver hydrogen to the bottom of the vessel and a stirring structure to mix the material with the solution. However, the existing hydrogen pipes are straight, resulting in a fixed hydrogen injection position. This prevents the material at the top from quickly contacting and mixing with the hydrogen, leading to slow mixing efficiency and affecting the hydrogenation reaction, thus impacting production efficiency.

[0019] The second connecting ring is fixedly connected to the inner top surface of the reactor body.

[0020] A circulation pipe is installed inside the reactor body. The inlet end of the circulation pipe is connected and fixed to the bottom of the first annular shell, and the outlet end of the circulation pipe is connected and fixed to the bottom of the second annular shell.

[0021] Preferably, the rotating assembly includes:

[0023] Motor 2 is fixedly connected to the top of the reactor body. The output end of motor 2 passes through the side wall of the reactor body and is fixedly connected to a gear. Motor 2 has a gear ring inside, which is fixedly connected to an annular shell 2 and meshes with the gear.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. By setting a mixing mechanism on the reactor body, and utilizing the reactor body to facilitate material storage, and using an electric heating ring to heat the inner wall of the reactor body, the material inside the reactor body is heated.

The hydrogen floating on the top of the reactor body can only contact the upper layer of the material, resulting in a low hydrogen utilization rate. By extracting the hydrogen floating on the top of the reactor body and re-transporting it to the inside of the connecting shell and rotating pipe, the utilization rate of hydrogen is improved, and the efficiency of the hydrogenation reaction is increased.

[0027] 3. By installing an adjustment mechanism on the reactor body and using multiple temperature sensors to monitor the temperature of the material inside the reactor body, cooling water or hot water is supplied to the circulation pipe.

By controlling the material temperature, the efficiency of the hydrogenation reaction is ensured. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1-7 In this embodiment of the present invention, a catalytic hydrogenation reactor includes a reactor body 100, a mixing mechanism 200, and a positioning mechanism 300. The reactor body 100 has a placement groove 101, and an electric heating ring 110 is fixedly connected to the inner side wall of the placement groove 101. The mixing mechanism 200 is disposed on the reactor body 100 for stirring the materials and conveying hydrogen. The positioning mechanism 300 is disposed on the reactor body 100.

[0038] Specifically, the reactor body 100 facilitates the storage of materials, and the electric heating ring 110 facilitates the heating of the inner wall of the reactor body 100, thereby heating the materials inside the reactor body 100. The mixing mechanism 200 facilitates the stirring of materials and the addition of hydrogen into the reactor body 100. The stirring process mixes the hydrogen with the materials to achieve the hydrogenation reaction. The adjusting mechanism 300 facilitates the adjustment of the temperature inside the reactor, ensuring the efficiency of the hydrogenation reaction and making it more convenient to use.

[0039] Example 1

[0040] like Figure 3-4 As shown, in this embodiment, the mixing mechanism 200 includes: a support frame 210, a motor 220, a rotating tube 230, and multiple fixed tubes 240. The support frame 210 is fixed to the top of the reactor body 100. The motor 220 is fixed to the top of the support frame 210. The output end of the motor 220 passes through the side wall of the support frame 210 and extends into the interior of the support frame 210. The rotating tube 230 is rotatably connected to the reactor body 100. The top of the rotating tube 230 is fixedly connected to the output end of the support frame 210. Multiple air inlets 231 are provided on the top of the rotating tube 230. Furthermore, an air supply assembly is provided on the outer side of the top of the rotating tube 230. Multiple temperature sensors are installed and fixed on the rotating tube 230. Multiple fixed tubes 240 are connected and fixed to the rotating tube 230. Multiple one-way valves 241 are connected and fixed on the fixed tubes 240. Two agitator plates 242 are symmetrically fixed to the outer wall of the fixed tubes 240. The air supply assembly includes a connecting shell 260. The connecting shell 260 is rotatably sleeved with the top of the rotating tube 230, and the bottom of the connecting shell 260 is fixed to the top of the reactor body 100. An electric control valve 261 is connected and fixed to the outer side of the connecting shell 260.

[0041] In this embodiment, by starting motor 220, the rotating tube 230 is rotated, which in turn causes multiple fixed tubes 240 and multiple agitator plates 242 to rotate, facilitating the mixing of materials. The outer hydrogenation pipe is connected to an electrically controlled valve 261, which, when opened, allows hydrogen to be delivered into the connecting shell 260. Multiple electrically controlled valves 261 deliver hydrogen into the rotating tube 230 and multiple fixed tubes 240, while multiple one-way valves 241 facilitate the discharge of hydrogen. This allows hydrogen to be delivered into the materials from multiple locations. The rotation of the fixed tubes 240 and multiple agitator plates 242 agitates the materials and hydrogen, improving the mixing efficiency of hydrogen and materials, thereby reducing the reaction time and increasing production efficiency.

[0042] like Figure 4 As shown, in this embodiment, an electrically controlled valve 262 is fixedly connected to the outer side of the connecting shell 260, and a peristaltic pump 250 is provided on the outer side of the connecting shell 260. The peristaltic pump 250 is fixedly connected to the top of the reactor body 100. A connecting pipe 251 is fixedly connected to the air inlet end of the peristaltic pump 250, and the connecting pipe 251 is fixedly connected to the top of the reactor body 100. A connecting pipe 252 is fixedly connected to the air outlet end of the peristaltic pump 250, and one end of the connecting pipe 252 is fixedly connected to the electrically controlled valve 261.

[0043] In practice, by starting the peristaltic pump 250 and opening the second electrically controlled valve 262, the hydrogen floating on the top of the reactor body 100 can be extracted and re-transported to the interior of the connecting shell 260 using the peristaltic pump 250, connecting pipe 1 251 and connecting pipe 252. The hydrogen floating on the top of the reactor body 100 can only contact the upper layer of the material, resulting in a low hydrogen utilization rate. By extracting the hydrogen floating on the top of the reactor body 100 and re-transporting it to the interior of the connecting shell 260 and the rotating pipe 230, the utilization rate of hydrogen is improved.

[0044] Example 2

[0045] Based on Example 1, the efficiency of the hydrogenation reaction was improved in order to control the temperature of the material inside the reactor body 100.

[0046] like Figure 5-7 As shown, in this embodiment, the adjusting mechanism 300 includes: a first connecting ring 310, a second connecting ring 320, and a circulation pipe 350. The first connecting ring 310 is fixedly connected to the inner top surface of the reactor body 100. A first conveying pipe 311 is fixedly connected to the top of the first connecting ring 310, and an annular shell 312 is rotatably connected to the bottom of the first connecting ring 310. The second connecting ring 320 is fixedly connected to the inner top surface of the reactor body 100. A second conveying pipe 321 is fixedly connected to the top of the second connecting ring 320, and an annular shell 322 is rotatably connected to the bottom of the second connecting ring 320. A rotating assembly is provided on the second connecting ring 320. The circulation pipe 350 is disposed within the inner surface of the reactor body 100. The circulation pipe 350 has its inlet end connected and fixed to the bottom of the annular shell 312, and its outlet end connected and fixed to the bottom of the annular shell 322. The rotating assembly includes a shielding shell 330 and a motor 340. The shielding shell 330 is fixedly connected to the inner top surface of the reactor body 100. The outer wall of the shielding shell 330 is rotatably connected to the annular shell 322. The motor 340 is fixedly connected to the top of the reactor body 100. The output end of the motor 340 passes through the side wall of the reactor body 100 and is fixedly connected to a gear 341. A gear ring 342 is provided inside the motor 340. The gear ring 342 is fixedly connected to the annular shell 322 and meshes with the gear 341.

[0047] Both annular shell 312 and annular shell 322 are annular shell structures with open tops. Connecting ring 310 and annular shell 312 are rotatably engaged, so that connecting ring 310 and annular shell 312 will not separate. Similarly, connecting ring 320 and annular shell 322 are also rotatably engaged, so that connecting ring 320 will not separate from annular shell 322.

[0048] In this invention, to facilitate operator control of the utility model, a PLC controller can be set up, and the electric heating ring 110, motor 220, multiple temperature sensors, peristaltic pump 250, electric control valve 261, electric control valve 262 and motor 340 are all electrically connected to the PLC controller. The PLC controller is existing technology and will not be described in detail here.

[0049] In specific implementation, multiple temperature sensors are used to monitor the temperature of the material inside the reactor body 100. A first delivery pipe 311 is connected to an external water pump, and a second delivery pipe 321 is connected to an external water tank. This allows for the convenient delivery of cooling water or hot water into the annular shell 312 via the external water pump and delivery pipe 311. The inlet of the circulation pipe 350 is connected to the annular shell 312, thus allowing for the delivery of cooling water or hot water into the circulation pipe 350. The annular shell 322 and delivery pipe 321 facilitate the discharge of cooling water or hot water. When cooling water flows inside the circulation pipe 350… Cooling water lowers the temperature of the circulation pipe 350, thereby lowering the temperature of the material. When hot water flows inside the circulation pipe 350, the hot water heats the circulation pipe 350, thereby increasing the temperature of the material. By starting the motor 340, the motor 340 drives the gear 341 to rotate, which in turn drives the gear ring 342, the annular shell 322, and the circulation pipe 350 to rotate. The rotating circulation pipe 350 can agitate and mix the material, and it also allows the circulation pipe 350 to come into contact with the material at different locations, thus increasing the rate at which the circulation pipe 350 adjusts the temperature of the material.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
