Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical engineering, in particular to a premixing device for a chemical reactor. Background Technique
[0002] A reactor is a reaction device. Generally speaking, a reactor is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are realized. It is a pressure vessel used to complete processes such as vulcanization, nitrification, hydrogenation, verticalization, polymerization, and condensation. Premixing is to premix the raw materials required by the reactor in advance so that after the premixing is completed, they can be fed into the reactor for reaction at any time.
[0003] For example, a premixing device for a chemical reactor described in the patent with the patent publication number CN220091048 U. The solution described therein includes a premixing cylinder, a feed inlet, and a discharge outlet. A premixing component is arranged inside the premixing cylinder. The premixing component includes a second motor. The second motor is installed at the top of the premixing cylinder. The output end of the second motor is connected with a coupling. A spiral rod is rotatably connected to the inner top of the premixing cylinder. The top end of the spiral rod penetrates through the premixing cylinder and is connected with the coupling. A hollow cylinder is connected to the inner top wall of the premixing cylinder. A through groove is opened at one end of the hollow cylinder. A connecting block is sleeved on the lower end of the outer part of the spiral rod. Three connecting frames are equally divided and connected to the outer part of the connecting block. One end of each connecting frame is equally divided and connected with a plurality of stirring blades.
[0004] The above case has the problem that the shaking frequency cannot be adjusted. The raw materials in the premixing barrel are based on actual needs, so the amount of raw materials in the premixing barrel is variable, and there will be more or less situations. When shaking the inside to prevent precipitation, different effects will occur according to the actual amount inside. The device can only shake at the same frequency. When the amount inside the premixing barrel is small, the shaking amplitude will be too large. When the amount inside the premixing barrel is large, the shaking will not be obvious, and thus precipitation will also occur. Content of the Utility Model

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0025] Embodiment 1
[0026] Please refer to Figures 1 - 3, the utility model includes a base 1. Above the base 1, there is a premixing barrel 2. At the top of the premixing barrel 2, there is a feed inlet. At the bottom of the premixing barrel 2, there is a discharge pipe. Inside the premixing barrel 2, there is a stirring assembly for stirring the raw materials. On the base 1, there is a chute. A sliding plate 3 is slidably connected in the chute. At the top of the sliding plate 3, there is a lifting assembly for lifting the premixing barrel 2. One side of the sliding plate 3 is fixedly connected to a connecting rod 4. At the other end of the connecting rod 4, there is a sliding frame 5. At the top of the base 1, there is also a U-shaped frame 6. At the bottom of the U-shaped frame 6, there is a shaking assembly for shaking the sliding plate 3. Through the stirring assembly, the raw materials inside the premixing barrel 2 can be stirred. Through the lifting assembly, the height of the premixing barrel 2 can be adjusted. Through the shaking assembly, the raw materials inside the premixing barrel 2 can be shaken.
[0027] As Figure 2 shown, the stirring assembly includes a first motor 7. The first motor 7 is fixedly connected to the top of the premixing barrel 2. The output end of the first motor 7 is fixedly connected to a stirring column 8. The stirring column 8 is rotatably connected inside the premixing barrel 2. And on the outer surface of the stirring column 8, there are stirring blades. By starting the first motor 7, it drives the stirring column 8 to rotate. The stirring column 8 drives the stirring blades to rotate inside the premixing barrel 2.
[0028] As Figure 1 and Figure 2 shown, the lifting assembly includes telescopic columns 9. The telescopic ends of the telescopic columns 9 are fixedly connected to the bottom of the premixing barrel 2. And between the telescopic columns 9, there is a support bar 10. An electric telescopic rod 11 is installed in the middle of the support bar 10. And the output end of the electric telescopic rod 11 is fixedly connected to the bottom of the premixing barrel 2. The bottoms of the telescopic columns 9 and the electric telescopic rod 11 are both fixedly connected to the top of the sliding plate 3. By starting the electric telescopic rod 11, it drives the premixing barrel 2 to move up and down. The telescopic columns 9 support the premixing barrel 2. The support bar 10 supports the electric telescopic rod 11.
[0029] As Figure 2 and Figure 3As shown in the figure, the shaking assembly includes a second motor 12, which is fixedly connected to the U-shaped frame 6. The output end of the second motor 12 is fixedly connected with an eccentric turntable 13. A limiting groove is formed on one side of the eccentric turntable 13. A slider 14 is slidably connected in the limiting groove. A convex column 15 is fixedly connected to the bottom of the slider 14. The convex column 15 is slidably connected in the sliding frame 5. An adjusting assembly for adjusting the slider 14 is arranged inside the slider 14. By starting the second motor 12, it drives the eccentric turntable 13 to rotate. The eccentric turntable 13 drives the slider 14, the slider 14 drives the convex column 15, and the convex column 15 drives the sliding frame 5 to move. When the convex column 15 rotates to both sides of the eccentric turntable 13, it will not drive the sliding frame 5, but slide inside it. When the convex column 15 rotates to the other two sides, it drives the sliding frame 5 to move. The sliding frame 5 drives the connecting rod 4, and the connecting rod 4 drives the premixing barrel 2.
[0030] As Figure 3 shown in the figure, the adjusting assembly includes a threaded rod 16, which is threadedly connected to the inside of the slider 14. The threaded rod 16 is rotatably connected in the limiting groove, and one end connecting shaft of the threaded rod 16 is rotatably connected to the inside of one side of the eccentric turntable 13. A turntable is arranged at the end of the threaded rod 16 away from the slider 14. By rotating the threaded rod 16, it drives the slider 14 to slide in the limiting groove, so as to change the distance between the convex column 15 and the center of the eccentric turntable 13.
[0031] As Figure 2 shown in the figure, a solenoid valve is arranged on the discharge pipe, and the opening and closing of the discharge pipe can be controlled through the solenoid valve.
[0032] As Figure 2 shown in the figure, the telescopic columns 9 are symmetrical to each other, and the telescopic ends of the telescopic columns 9 have the same length as the telescopic ends of the electric telescopic rods 11, preventing the premixing barrel 2 from tilting when rising or falling.
[0033] Embodiment 2
[0034] As Figure 2 shown in the figure, the difference from Embodiment 1 is that connecting rods 17 are arranged in both the upper-middle part and the lower-middle part of the stirring column 8. The other ends of the connecting rods 17 are provided with cleaning blocks 18, and the cleaning blocks 18 are in mutual contact with the inside of the premixing barrel 2, so that the cleaning blocks 18 rotate together with the stirring column 8, thereby preventing raw materials from adhering to the inner wall of the premixing barrel 2.
[0035] The working principle of the present utility model is as follows: The operator adds the raw materials to be premixed at the feeding port, and then starts the first motor 7 to drive the stirring column 8 to rotate. The stirring column 8 drives the stirring blades to rotate inside the premixing barrel 2, thereby stirring the raw materials inside the premixing barrel 2. After the stirring is completed, in order to prevent precipitation, the second motor 12 can be started to drive the eccentric turntable 13 to rotate. The eccentric turntable 13 drives the slider 14, the slider 14 drives the convex column 15, and the convex column 15 drives the sliding frame 5 to move. When the convex column 15 rotates to both sides of the eccentric turntable 13, it will not drive the sliding frame 5 but slide inside it. When the convex column 15 rotates to the other two sides, it drives the sliding frame 5 to move. The sliding frame 5 drives the connecting rod 4, and the connecting rod 4 drives the premixing barrel 2, thereby shaking the raw materials inside it to prevent precipitation. In actual operation, the shaking frequency can be adjusted according to the capacity of the raw materials. By rotating the threaded rod 16, the slider 14 can be driven to slide in the limiting groove, thereby changing the distance from the convex column 15 to the center of the eccentric turntable 13, and thus changing the shaking frequency. Finally, when the raw materials need to flow into the reaction kettle, the electric telescopic rod 11 can be started to drive the premixing barrel 2 to move up and down, so that the reaction kettle can be aligned with the discharge pipe at the bottom of the premixing barrel 2, and then the output of the raw materials is controlled by the solenoid valve.
[0036] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
