Technical Field

[0001] The utility model relates to the technical field of ethanol extraction, in particular to an ethanol recovery device for ethanol extraction waste liquid. Background Art

[0002] Ethanol extraction is a commonly used solvent extraction method that uses ethanol as a solvent to extract target compounds from plants or other substances. If necessary, ethanol can be separated and recovered from the concentrate by distillation or other methods for reuse.

[0003] At present, the existing ethanol recovery device (such as announcement number: CN215136973U) discloses a distillation reactor, which is provided with a connecting piece. When the reactor body needs to be cleaned, the staff can remove the top cover from the reactor body by disassembling the connecting piece, so that the inside of the reactor body can be cleaned, and the disassembly and installation process is relatively simple. At the same time, an insulating shell is provided, which can prevent the waste heat generated during the heating process of the device from diffusing to the outside to a certain extent.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the solution inside the reactor is evaporated by heating, the steam is cooled by a condensing device, and re-condensed into a solution for collection; the condenser is directly connected to the steam pipe, and the specifications of the condenser are fixed. When the steam temperature inside the pipe changes, the condenser cannot be adjusted according to the temperature, and has certain limitations in use. Utility Model Content

[0020] The embodiment of the present application provides an ethanol recovery device for ethanol extraction waste liquid, which effectively solves the problem of cooling the steam through a condensing device, re-condensing it into a solution, and collecting it. The condenser is directly connected to the steam pipe, and the specifications and sizes of the condenser are fixed. When the steam temperature inside the pipe changes, the condenser cannot be adjusted according to the temperature, and has certain limitations in use.

The end of the push rod is rotatably connected to the end of the cooler, pushing the end of the cooler to move to one side. At the same time, the top of the cooler is fixed on the surface of the connecting pipe, and is subjected to the force, so that the sealing sleeve moves and stretches inside the cooler, thereby increasing the coverage of the connecting pipe.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem of cooling the steam through the condensing device, re-condensing it into a solution, and collecting it. The condenser is directly connected to the steam pipeline, and the size of the condenser is fixed. When the steam temperature inside the pipeline changes, the condenser cannot be adjusted according to the temperature, and there are certain technical limitations in use. The overall idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides an ethanol recovery device for ethanol extraction waste liquid, the ethanol recovery device comprises a distillation kettle 1, a connecting pipe 11 is fixedly installed on the top of the distillation kettle 1, a cooler 12 is fixedly installed on the surface of the connecting pipe 11, a sealing sleeve 17 is movably installed inside the cooler 12, two support plates 15 are fixedly installed on the surface of the cooler 12, a T-shaped slider 19 is slidably installed on the outer side of each support plate 15, a push rod 16 is rotatably installed on the side end of each T-shaped slider 19, and the cooler 12 is a segmented design One end of the cooler 12 is fixedly connected to the connecting pipe 11, and the other end can be moved. The inner side of the sealing sleeve 17 is a sandwich design. By pushing the T-shaped slider 19, the T-shaped slider 19 is moved up and down on the side end of the support plate 15. The movement of the T-shaped slider 19 pushes the inclined push rod 16 to move. The end of the push rod 16 is rotatably connected to the end of the cooler 12, pushing the end of the cooler 12 to move to one side. At the same time, the top end of the cooler 12 is fixed to the surface of the connecting pipe 11, and is subjected to the force, allowing the sealing sleeve 17 to move and stretch inside the cooler 12.

[0024] The two side ends of the cooler 12 are fixedly installed with a closed ring 13, and the side ends of each T-shaped slider 19 are slidably installed with a positioning block 22, and the side ends of each positioning block 22 are fixedly installed with a first reset rod 21, and the bottom end of each T-shaped slider 19 is fixedly installed with a second reset rod 23. A slot 18 is provided on the inner side of the cooler 12. By releasing the thrust on the positioning block 22, under the reverse force of the first reset rod 21, the top end of the first reset rod 21 applies a horizontal thrust to the positioning block 22, so that the positioning block 22 slides out on one side of the T-shaped slider 19 and docks with the bayonet on the outside of the support plate 15 to fix the position of the T-shaped slider 19. Two circulation pipes 14 are fixedly installed on the top of the cooler 12.

[0025] Working principle:

[0026] In the first step, the ethanol solution is transported to the inner wall of the still 1 through the pipe at the top of the still 1, and the still 1 is heated by the heating device. The temperature of the ethanol inside the still 1 rises, and steam is generated. The steam is transported to the outside through the connecting pipe 11, and a cooler 12 is installed on the outside of the connecting pipe 11. Two circulation pipes 14 are installed on the top of the cooler 12. The circulation pipe 14 guides cooling water into the inside of the cooler 12 to cool the connecting pipe 11. The difference in volatility of each component in the liquid mixture is used to partially vaporize the liquid mixture and then cool the steam part, so that the ethanol is extracted and recovered. In use, the positioning block 22 can be moved on one side of the T-shaped slider 19 by pushing the fixed plate outside the positioning block 22. The positioning block 22 moves to the inside of the T-shaped slider 19, and the positioning block 2 2 squeezes the top of the first reset rod 21, forcing the first reset rod 21 to be compressed inside the T-shaped slider 19. At the same time, the top of the positioning block 22 moves away from the bayonet on one side of the support plate 15, releasing the limit of the T-shaped slider 19. By pushing the T-shaped slider 19, the T-shaped slider 19 is moved up and down on the side end of the support plate 15. The movement of the T-shaped slider 19 pushes the inclined push rod 16 to move. The end of the push rod 16 is rotatably connected to the end of the cooler 12, pushing the end of the cooler 12 to move to one side. At the same time, the top of the cooler 12 is fixed to the surface of the connecting pipe 11, and the sealing sleeve 17 is subjected to the force to move and stretch inside the cooler 12, thereby increasing the coverage of the connecting pipe 11 and the cooling speed. It can be adjusted according to the temperature of the ethanol vapor, thereby improving the versatility of the equipment.

[0027] The second step is to move the T-shaped slider 19 so that the T-shaped slider 19 moves up and down on the side end of the support plate 15, and the end of the T-shaped slider 19 squeezes the second reset rod 23. At the same time, the T-shaped slider 19 moves downward, exerts downward extrusion on the second reset rod 23, forcing the second reset rod 23 to be compressed. The top end of the second reset rod 23 will exert an upward thrust on the T-shaped slider 19, which can quickly reset the T-shaped slider 19. Since the cooler 12 is designed in sections as a whole, the internal components are movably connected. By moving the T-shaped slider 19, the push rod 16 exerts a force on one side of the cooler 12 to adjust the length of the cooler 12. By releasing the thrust on the positioning block 22, under the reverse force of the first reset rod 21, the top end of the first reset rod 21 exerts a horizontal thrust on the positioning block 22, allowing the positioning block 22 to slide out on one side of the T-shaped slider 19 and dock with the bayonet on the outside of the support plate 15, thereby fixing the position of the T-shaped slider 19, which is convenient to operate.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description.
