Specific implementation mode
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1 - 4 , in order to solve the problem that when the extraction solvent reacts with alkanes and alkenes, it is difficult to quickly stir and mix, resulting in a decrease in mass transfer efficiency and affecting the overall extraction efficiency, the following preferred technical solutions are provided:
[0023] A device for reducing fusel oil in alkane and alkene extraction includes a reaction body 1 and an outer mounting frame 2 installed on the outer wall of the reaction body 1. A support frame 3 is fixedly connected to the lower end of the outer mounting frame 2. A discharge pipe 4 is arranged at the lower end of the reaction body 1, and a feed main body 5 is arranged at the upper end of the reaction body 1. A mixing mechanism 6 is installed in the cavity of the reaction body 1. The mixing mechanism 6 includes a driving gear 61. A control rod 62 is fixedly connected to the center of the driving gear 61. A driven gear 63 is meshed and connected to one side of the driving gear 61. A rotating rod 64 is fixedly connected to the inner wall of the driven gear 63. The outer wall of the rotating rod 64 is provided with a first connecting plate 65 and a second connecting plate 66. Mixing screens 67 are arranged on the outer walls of the first connecting plate 65 and the second connecting plate 66. Cleaning blocks 68 are installed at both ends of the first connecting plate 65 and the second connecting plate 66.
[0024] Both the driving gear 61 and the driven gear 63 are rotatably connected to the upper wall of the reaction body 1. The first connecting plate 65 and the second connecting plate 66 are perpendicularly distributed, and the lengths of the first connecting plate 65 and the second connecting plate 66 match the inner diameter of the cavity of the reaction body 1.
[0025] The cleaning block 68 is a component made of rubber, and the inside of the cleaning block 68 is a hollow structure. The inner wall of the cleaning block 68 is axially connected with a first push plate 69 and a second push plate 610. The opposite ends of the first push plate 69 and the second push plate 610 are axially connected. A top block body 611 is installed at the connection of the first push plate 69 and the second push plate 610. One end of the top block body 611 away from the first push plate 69 and the second push plate 610 is fixedly connected with an elastic element 612. The elastic element 612 is fixedly connected with the side wall of the cleaning block 68 away from the top block body 611. The first push plate 69, the second push plate 610, the top block body 611 and the cleaning block 68 are all provided with two groups, and are symmetrically distributed about the center of the cleaning block 68.
[0026] Specifically, when it is necessary to perform extraction work on the fusel alcohols of alkenes and alkanes, first, the alkenes and alkanes and the extraction solvent are introduced into the cavity of the reaction body 1 through the feeding main body 5 in proportion. At this time, the control rod 62 is rotated, and the control rod 62 is used to drive the driving gear 61 to rotate. The driven gear 63 is driven to rotate by the driving gear 61, so that the driven gear 63 drives the first connecting plate 65 and the second connecting plate 66 to rotate through the rotating rod 64, thereby stirring and mixing the alkenes and alkanes and the extraction solvent. The alkenes and alkanes and the extraction solvent continuously pass through the mixing mesh 67 on the first connecting plate 65 and the second connecting plate 66, thereby greatly increasing the mixing speed, and solving the problem that when the extraction solvent reacts with the alkenes and alkanes, it is difficult to quickly stir and mix, resulting in a decrease in mass transfer efficiency and affecting the overall extraction efficiency.
[0027] When the first connecting plate 65 and the second connecting plate 66 rotate, the cleaning block 68 will be squeezed by the inner wall of the reaction body 1, causing the outer wall of itself to sink inward, thereby driving the angle between the first push plate 69 and the second push plate 610 to become smaller, driving the top block body 611 to compress the elastic element 612. At this time, by using the reaction force of the elastic element 612, the outer wall of the cleaning block 68 will be driven to recover, so that the outer wall of the cleaning block 68 tightly fits the inner wall of the reaction body 1. Therefore, as the cleaning block 68 rotates, the inner wall of the reaction body 1 can be cleaned to avoid liquid adhesion.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
