Description

Technical Field

[0001] The utility model relates to the technical field of alcohol distillation, in particular to an alcohol evaporation and concentration device. Background Art

[0002] Wine is a liquid made from grains through fermentation. Its main chemical component is ethanol, which generally contains trace amounts of fusel alcohols. It is a drink with national cultural characteristics. During the fermentation process of edible wine, yeast converts sugars into alcohol and other products. Since yeast undergoes protein denaturation under high alcohol concentrations, it will gradually die as the alcohol concentration increases. Therefore, the alcohol concentration that edible wine can achieve through natural fermentation is limited. High-proof edible wine needs to be further processed to increase the alcohol concentration on the basis of natural fermentation.

[0003] As an indispensable device for alcohol concentration, distillation equipment mainly uses the difference in boiling points between alcohol and water. The alcohol output pipe of the existing alcohol evaporation and concentration equipment is relatively long to ensure that the rectified alcohol can be condensed. The long condensation pipe occupies a relatively large space, and after a certain period of condensation, the condensation pipe will absorb a certain amount of heat. The condensation pipes in the prior art are all exposed to the outside, and their own heat dissipation and cooling rely entirely on the natural environment, which is relatively slow, so a longer condensation pipe is required.

[0004] Therefore, we propose a device for alcohol evaporation and concentration to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an alcohol evaporation and concentration device to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An alcohol evaporation and concentration device comprises a distillation tank, a condensation pipe with a distillation hood is butt-jointedly mounted on the top of the distillation tank, an auxiliary box is mounted on the right side surface of the distillation tank via fasteners, an air inlet pipe is mounted on the top of the auxiliary box, a rectifier pipe is butt-jointedly mounted on the top of the air inlet pipe, a hollow shaft is connected through the side of the auxiliary box, a metal sheet is arranged on the outer ring of the hollow shaft located in the inner cavity of the distillation tank, and a linkage sheet is arranged on the outer ring of the hollow shaft located in the inner cavity of the auxiliary box.

[0008] Preferably, the bottom of the air inlet pipe is communicated with the inner cavity of the attached box, and the top of the air inlet pipe is communicated with the inner cavity of the rectifier tube.

[0009] Preferably, the rectifying tube is sleeved on the outer ring of the condensing pipe, and the upper part of the air inlet pipe and the bottom of the rectifying tube are designed to be inclined at an angle of 60°.

[0010] Preferably, the portion of the hollow shaft that passes through the distillation tank is installed with a mechanical seal, and the hollow shaft is located between the mechanical seal and the right side surface of the auxiliary box and is installed through a bearing.

[0012] Preferably, a bottom port for drawing cold air is provided at the bottom of the auxiliary box.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the alcohol evaporation and concentration device, cold air enters the space between the outer wall of the condensation pipe and the inner wall of the rectifier pipe through the air inlet pipe. Such cold air can directly and accurately act on the condensation pipe, dissipate heat and cool the condensation pipe, improve the alcohol condensation efficiency, and speed up the condensation speed of the alcohol gas that has just entered the inner cavity of the condensation pipe, avoiding the problem of reflux caused by the increase of internal pressure of the condensation pipe.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a technical solution for an alcohol evaporation and concentration device:

[0022] Embodiment 1:

[0023] The concentrating device mainly comprises a distillation tank 1, a condensation pipe 2 is butt-jointedly installed on the top of the distillation tank 1, an auxiliary box 3 is installed on the side wall of the distillation tank 1 by fasteners, an air inlet pipe 4 is installed on the top of the auxiliary box 3, a rectifying pipe 5 is set on the side of the outer circle of the condensation pipe 2 close to the distillation tank 1, a hollow shaft 7 is penetrated and connected to the side of the auxiliary box 3, a metal sheet 8 is arranged on the outer circle of the hollow shaft 7 located in the inner cavity of the distillation tank 1, and a linkage sheet 10 is arranged on the outer circle of the hollow shaft 7 located in the inner cavity of the auxiliary box 3.

[0024] Among them, the bottom of the air inlet pipe 4 is connected with the inner cavity of the auxiliary box 3, and the top of the air inlet pipe 4 is connected with the inner cavity of the rectifier tube 5. The bottom of the auxiliary box 3 is open, which is mainly used to draw cold air from the bottom of the auxiliary box 3. It is mainly based on the characteristics of the air itself, that is, the air with relatively low temperature sinks, so the air is drawn from a relatively low position.

[0025] Among them, a mechanical seal 9 is provided at the position where the hollow shaft 7 passes through the distillation tank 1, mainly to maintain the overall sealing of the distillation tank 1 while ensuring the rotation of the hollow shaft 7 when distilling concentrated alcohol.

[0026] In this embodiment, a sewage outlet is provided at the bottom of the distillation tank 1, and a feeding port is provided on the side of the distillation tank 1. An alcohol solution with a relatively low concentration is directly fed into the inner cavity of the distillation tank 1, and then evaporation and concentration can be performed. The alcohol is distilled and concentrated by controlling the temperature. During the distillation process, the vaporized alcohol will continuously move upward, and the flowing alcohol airflow will hit the metal sheet 8. The entire hollow shaft 7 first adopts a hollow design mainly to reduce weight. On the other hand, bearings are installed at the right end of the central shaft 7 and the mechanical seal position, so that the alcohol airflow gently hits the metal sheet 8. It drives the metal sheet 8 and the hollow shaft 7 to rotate. When the hollow shaft 7 rotates, it drives the linkage piece 10 thereon to rotate. When the linkage piece 10 rotates, the cold air at the bottom of the accessory box 3 is sucked in, and enters the space between the outer wall of the condensation pipe 2 and the inner wall of the rectifier pipe 5 through the air inlet pipe 4. Such cold air can directly and accurately act on the condensation pipe 2, and can dissipate heat and cool the condensation pipe 2. While improving the alcohol condensation efficiency, it can also speed up the condensation speed of the alcohol gas that has just entered the inner cavity of the condensation pipe 2, and avoid the problem of reflux caused by the increase in internal pressure of the condensation pipe 2.

[0027] Embodiment 2:

[0028] Threaded holes are provided at equal distances on the outer wall of the rectifier tube 5, and a threaded rod 6 is threadedly installed in the inner cavity of the threaded hole.

[0029] In this embodiment, first, when the rectifier tube 5 is installed, the threaded rod 6 can fix the rectifier tube 5 on the outer ring of the condensation pipe 2. At the same time, after the installation is completed, one end of the threaded rod 6 is against the outer wall of the condensation pipe 2, and the heat exchange of the condensation pipe just entering the alcohol vapor section is accelerated through the special heat conductivity of the metal.
