Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0027] In one embodiment, such as Figures 1-3As shown, a reactor for the synthesis of umbelliferous hydrocarbons includes: a base 100, a reactor body 200, a hollow jacket 300, and a stirring assembly. The reactor body 200 is disposed above the base 100, and the hollow jacket 300 is disposed on the outer surface of the reactor body 200. The stirring assembly includes a support frame 401, which is disposed on the top of the reactor body 200. A motor 402 is disposed on the top of the support frame 401. The output end of the motor 402 passes through the support frame 401 and is provided with a first rotating gear 403. The first rotating gear 403 is meshed with a second rotating gear 404. Hollow columns 405 are rotatably connected inside both the support frame 401 and the reactor body 200, and the interior of the second rotating gear 404 is connected to the hollow column 405. The hollow column 405 is fixedly connected to the outer surface of the reactor body 200. A spiral blade 406 is also provided on the outer surface of the hollow column 405. A cleaning assembly for cleaning the interior of the reactor body 200 is provided on the hollow column 405. A heating assembly for heating the reactor body 200 is provided on the hollow jacket 300. A discharge assembly for discharging air from inside the hollow jacket 300 is provided on the hollow jacket 300. A support assembly for supporting the hollow jacket 300 is provided on the top of the base 100. By starting the motor 402, the first rotating gear 403 is driven to rotate, thereby driving the second rotating gear 404 and the hollow column 405 to rotate, thus causing the spiral blade 406 to rotate inside the reactor body 200.
[0028] In one embodiment, such as Figure 1 and Figure 2 As shown, the cleaning assembly includes a rotary joint 501 located at the top of a hollow column 405. Several water outlet holes 502 are formed on the outer surface of the hollow column 405. Connecting rods 503 are provided at one end of the upper and lower parts of the hollow column 405. Cleaning strips 504 are provided at the ends of the two connecting rods 503 that are far apart from each other. Water is connected to the rotary joint 501, allowing water to reach the interior of the hollow column 405 and then be discharged through the water outlet holes 502. The rotation of the hollow column 405 also drives the two connecting rods 503 to rotate, thereby causing the cleaning strips 504 to move and clean the inner wall of the reactor body 200.
[0029] In one embodiment, such as Figure 1 and Figure 2As shown, the heating assembly includes a water tank 601, which is located on top of the base 100. A water pump is installed inside the water tank 601, and the output end of the water pump is provided with a water outlet pipe 602. A steam generator 603 is provided on one end of the cavity jacket 300, and the other end of the water outlet pipe 602 passes through the water tank 601 and is located at the input end of the steam generator 603. The output end of the steam generator 603 passes through the cavity jacket 300 and is located inside the cavity jacket 300. By starting the water pump, water inside the water tank 601 is pumped to the water outlet pipe 602, and then reaches the steam generator 603. The water is then converted into steam and discharged into the cavity jacket 300.
[0030] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the emission assembly includes an exhaust pipe 701, which is located at the top of the cavity jacket 300. A limiting ball 702 is slidably connected inside the exhaust pipe 701. An electric push rod 703 is provided at one end of the top of the reactor body 200. A support plate is provided at the output end of the electric push rod 703. A connecting rod 704 is provided at the bottom of the support plate. The other end of the connecting rod 704 passes through the exhaust pipe 701 and is connected to the limiting ball 702. Several exhaust holes 705 are also provided on the exhaust pipe 701. By activating the electric push rod 703, the support plate and the connecting rod 704 are raised and lowered, thereby raising and lowering the limiting ball 702, so that steam can be discharged from the exhaust holes 705.
[0031] In one embodiment, such as Figure 1 and Figure 2 As shown, the support assembly includes a plurality of support columns 801, all of which are disposed on the top of the base 100. Each of the support columns 801 has a support ring 802 at its top. The inside of the support ring 802 is connected to the outer surface of the cavity jacket 300. The support columns 801 support the support ring 802, and the support ring 802 then provides fixed support for the cavity jacket 300.
[0032] In one embodiment, such as Figure 1 As shown, a temperature gauge is provided on the top of the reactor body 200 to facilitate observation of temperature changes inside the reactor body 200.
[0033] In one embodiment, such as Figure 1 and Figure 2As shown, both ends of the top of the reactor body 200 are provided with inlets, and the bottom of the reactor body 200 is provided with a discharge pipe, and the discharge pipe is equipped with a solenoid valve. Cyperine and reagents for synthesis can be added to the reactor body 200 through the inlets, and the contents of the reactor body 200 can be discharged through the discharge pipe. The solenoid valve can control its opening and closing.
[0034] In one embodiment, such as Figure 2 As shown, both cleaning strips 504 are in contact with the inner wall of the reactor body 200.
[0035] The above embodiment discloses a reactor for synthesizing cymene. Cymene and synthesis reagents are added to the feed inlet. Then, a motor 402 is started, driving a first rotating gear 403 to rotate, which in turn drives a second rotating gear 404 and a hollow column 405 to rotate. This causes the spiral blades 406 to rotate inside the reactor body 200, thus mixing the cymene and synthesis reagents. A water pump is then started, drawing water from the water tank 601 to the outlet pipe 602, which then reaches the steam generator 603. The water is then converted into steam and discharged into the hollow jacket 300, thereby heating the reactor body 200. Upon completion of the synthesis, if the height inside the reactor body 200 is too high, the electric push rod 703 can be activated to raise and lower the support plate and connecting rod 704, thereby raising and lowering the limit ball 702. This allows steam to be discharged from the exhaust port 705. After the synthesis is complete, the steam can be discharged through the discharge pipe. When it is necessary to clean the inside of the reactor body 200, a water source can be connected to the rotary joint 501. The water then reaches the hollow column 405 and is discharged through the water outlet 502. The rotation of the hollow column 405 will also drive the two connecting rods 503 to rotate, thereby moving the cleaning strip 504 on the inner wall of the reactor body 200 for cleaning.
[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
