Description

Technical Field

[0001] This utility model relates to the field of alcohol distillation technology, and in particular to an alcohol distillation reflux and diversion device. Background Technology

[0002] Alcohol distillation is a process of separating and purifying alcohol (ethanol) through heating and condensation. It is often used to produce high-concentration alcohol or to brew alcoholic beverages. When distilling alcohol, the alcohol vapor generated by heating needs to be transported to a condensing device for liquefaction.

[0003] Existing alcohol distillation methods typically involve directly transporting alcohol vapor through an exhaust pipe to a condenser for cooling and liquefaction. Residual vapor is then returned to the distillation tank via a reflux pipe for recycling. However, because the condenser cannot divert the vapor during cooling, the liquefaction efficiency is low, resulting in poor performance. Furthermore, some residual vapor is discharged into the environment along with the collected liquid alcohol, leading to waste and poor overall efficiency. During the reflux process, the vapor cools as it flows through the pipes, affecting the temperature inside the distillation tank and further compromising performance. Therefore, we propose an alcohol distillation reflux and diversion device. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing an alcohol distillation reflux and diversion device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an alcohol distillation reflux and diversion device is designed, including a base plate, a distillation tank is installed at one end of the top of the base plate, and a condenser is provided at the top of the base plate. One side of the condenser is installed on a support frame by a fixing bracket, and the support frame is fixed to the top of the base plate. The condenser is equipped with a lid at both the top and bottom, and a second reflux pipe is installed on one side of the bottom of the condenser. One end of the second reflux pipe is fixed to the air inlet of the delivery pump. The delivery pump is fixed to the side of the mounting bracket by a mounting plate, and the air outlet of the delivery pump is connected to the first reflux pipe. The other end of the first reflux pipe is fixed to the top of the distillation tank. The side of the first reflux pipe is provided with two insulation jackets. Each insulation jacket is arc-shaped. When the close surfaces of the two insulation jackets abut, a cylindrical space is formed between the two insulation jackets, and the first reflux pipe is located in this space. Air channels are provided on the inner walls of both insulation jackets. When the two insulation jackets are close together, the two sets of air channels form a spiral channel. A first exhaust pipe is installed on the side of one of the insulation jackets. One end of the first exhaust pipe is connected to one end of the air channel, and the other end of the first exhaust pipe is fixed to the top of the distillation tank and connected to the inside of the distillation tank. A second exhaust pipe is installed on one side of the bottom of one of the insulation jackets. One end of the second exhaust pipe is connected to the air channel, and the other end of the second exhaust pipe is fixed to the tank cover installed on the top of the condenser and connected to the inside of the condenser. Two partition plates are symmetrically installed inside the condenser. Each partition plate has a vent hole at its top. Several heat exchange tubes are installed between the two partition plates. Both ends of the heat exchange tubes are fixed to the adjacent surfaces of the two partition plates, and each heat exchange tube is connected to the vent hole.

[0006] Preferably, the bottom of the insulation jacket is higher than the top of the can lid.

[0007] Preferably, the inner surface of each insulation jacket is sealed to the side of the first return pipe.

[0008] Preferably, each insulation jacket is equipped with threaded joints at both ends, and two fastening screw sleeves are slidably fitted on the first return pipe. When the two threaded joints at the same end are close to each other, the fastening screw sleeves are fitted onto the corresponding pair of threaded joints and threadedly connected to the threaded joints.

[0009] Preferably, when the proximal ends of the two insulation jackets abut each other, the proximal ends of the two insulation jackets are sealed together.

[0010] Preferably, two delivery pipes are installed on the side of the condenser between two partition plates, and the other end of each delivery pipe is connected to the refrigeration mechanism.

[0011] Preferably, the bottom of the tank cover installed at the lower end of the condenser is connected to a drain pipe, the other end of which is connected to a collection device, and the end of the drain pipe near the tank cover is located below the bottom of the second return pipe.

[0012] The design scheme proposed in this utility model has the following beneficial effects in application: 1. By installing partition plates inside the condenser and multiple heat exchange tubes between the partition plates, the steam can be divided and cooled, ensuring thorough cooling. Furthermore, the residual steam after condensation can be returned to the distillation tank through the first and second reflux pipes via a transfer pump for recycling, preventing residual alcohol vapor from being released to the outside and thus avoiding waste, thereby improving the efficiency of use.

[0013] 2. By delivering the steam discharged from the distillation tank into the insulation jacket, the steam flowing along the gas guide channel can heat the steam in the first reflux pipe, preventing the steam temperature in the first reflux pipe from dropping and affecting the temperature inside the distillation tank, thus improving the performance.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-4 An alcohol distillation reflux diversion device includes a base plate 1, a distillation tank 2 mounted on one top end of the base plate 1, and a condenser 13 mounted on the top of the base plate 1. One side of the condenser 13 is mounted on a support frame 16 via a fixing bracket 14, and the support frame 16 is fixed to the top of the base plate 1. Both the upper and lower ends of the condenser 13 are fitted with tank covers 15, and a second reflux pipe 10 is mounted on one side of the bottom of the condenser 13. One end of the second reflux pipe 10 is fixed to the air inlet of a delivery pump 8. The delivery pump 8 is fixed to the side of the fixing frame 14 via a mounting plate 9, and the air outlet of the delivery pump 8 is connected to a first reflux pipe 4. The other end of the first reflux pipe 4 is fixed to the top of the distillation tank 2. In actual use, the residual vapor inside the condenser 13 can be transported back to the distillation tank 2 by the delivery pump 8 through the second reflux pipe 4 and the first reflux pipe 10 for circulation, thus avoiding the waste of alcohol in the residual vapor.

[0018] like Figure 2 and Figure 3As shown, the side of the first return pipe 4 is provided with two heat insulation jackets 5. Each heat insulation jacket 5 is arc-shaped. When the close surfaces of the two heat insulation jackets 5 abut, a cylindrical space is formed between the two heat insulation jackets 5. The first return pipe 4 is located in this space. A gas guiding channel 17 is opened on the inner wall of the two heat insulation jackets 5. When the close surfaces of the two heat insulation jackets (5) abut, the two sets of gas guiding channels (17) form a spiral channel. A first exhaust pipe 3 is installed on the side of one of the heat insulation jackets 5. One end of the first exhaust pipe 3 is connected to one end of the gas guiding channel 17, and the other end of the first exhaust pipe 3 is fixed to the steam... The top of the distillation tank 2 is connected to the interior of the distillation tank 2. A second exhaust pipe 6 is installed on one side of the bottom of one of the insulation jackets 5. One end of the second exhaust pipe 6 is connected to the gas guide channel 17, and the other end of the second exhaust pipe 6 is fixed to the tank cover 15 installed on the top of the condenser tank 13 and connected to the interior of the condenser tank 13. In actual use, the vapor generated by the evaporation of the alcohol solution in the distillation tank 2 can be discharged into the gas guide channel 17 through the first exhaust pipe 3 to heat the vapor in the first return pipe 4. Then the vapor is transported to the condenser tank 13 through the second exhaust pipe 6 for cooling and collection.

[0019] It should be noted that the inner surface of each insulation jacket 5 is sealed to the side of the first return pipe 4, and when the near ends of two insulation jackets 5 abut each other, the near ends of the two insulation jackets 5 are sealed to each other, so that alcohol vapor will not leak when it flows in the gas guide channel 17.

[0020] It should be noted that, as Figure 1 and Figure 3 As shown, each insulation jacket 5 has a threaded connector 18 installed at both ends, and two fastening sleeves 7 are slidably fitted on the first return pipe 4. When the two threaded connectors 18 at the same end are close to each other, the fastening sleeves 7 are fitted on the corresponding pair of threaded connectors 18 and threadedly connected to the threaded connectors 18. The two insulation jackets 5 can be fixed together by the fastening sleeves 7, and then the insulation jackets 5 are fixed on the side of the first return pipe 4. The fixing is simple.

[0021] like Figure 1 and Figure 4As shown, two partition plates 20 are symmetrically installed inside the condenser tank 13. Each partition plate 20 has a vent hole 19 at its top. Several heat exchange tubes 21 are arranged between the two partition plates 20, with both ends of each tube fixed to the adjacent surfaces of the two partition plates 20. Each heat exchange tube 21 is connected to the vent hole 19. Two conveying pipes 11 are installed on the side of the condenser tank 13 between the two partition plates 20. The other end of each conveying pipe 11 is connected to the refrigeration mechanism. In actual use… The refrigeration unit can deliver low-temperature refrigerant to the condenser tank 13 through one of the delivery pipes 11, where it comes into contact with the heat exchange tube 21. The refrigerant is then discharged into the refrigeration unit through another delivery pipe 11 for circulation cooling. At the same time, the steam flowing into the condenser tank 13 can flow into the heat exchange tube 21 through the vent 19. The refrigerant can cool the steam in the heat exchange tube 21, causing the alcohol in the steam to liquefy and flow along the heat exchange tube 21 to the bottom of the condenser tank 13, resulting in sufficient cooling and improved performance.

[0022] like Figure 1 and Figure 4 As shown, the bottom of the tank cover 15 installed at the lower end of the condenser 13 is connected to a drain pipe 12. The other end of the drain pipe 12 is connected to a collection device, and the end of the drain pipe 12 near the tank cover 15 is located below the bottom of the second return pipe 10. The liquefied alcohol can be transported to the external collection mechanism through the drain pipe 12. In this way, when the transfer pump 8 is sucking up the alcohol vapor remaining inside the condenser 13, the liquefied alcohol liquid will not be sucked up by the transfer pump 8.

[0023] Specifically, in use, the vapor generated by the evaporation of the alcohol solution in the distillation tank 2 can be discharged into the insulation jacket 5 through the first exhaust pipe 3. The vapor is then transported to the second exhaust pipe 6 through the gas guide channel 17, and then discharged into the condenser tank 13 through the second exhaust pipe 6. After that, the vapor flows into the heat exchange tube 21 along the gas guide channel 17. At the same time, the refrigeration mechanism transports refrigerant to the condenser tank 13 through one of the delivery pipes 11, which contacts the heat exchange tube 21 to cool the vapor in the heat exchange tube 21. The alcohol in the vapor liquefies and flows along the heat exchange tube 21 to the bottom of the condenser tank 13, and is discharged through the drain pipe 12. At the same time, the operator controls the delivery pump 8 to work. The delivery pump 8 transports the residual alcohol vapor in the condenser tank 13 to the first return pipe 4 through the second return pipe 10, and finally discharges it into the distillation tank 2 for circulation. Meanwhile, the vapor flowing in the gas guide channel 17 can keep the vapor in the first return pipe 4 warm, preventing the temperature of the vapor in the first return pipe 4 from decreasing and affecting the temperature in the distillation tank 2.

[0024] Furthermore, such as Figure 1As shown, the bottom of the insulation jacket 5 is higher than the top of the tank cover 15, so that when the alcohol vapor liquefies in the second exhaust pipe 6, the liquefied liquid can flow into the condenser tank 13 through the second exhaust pipe 6, and the alcohol liquid will not remain in the gas guide channel 17 or the second exhaust pipe 6.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
