Description

Technical Field

[0001] The utility model belongs to the field of alcohol precipitation equipment, and particularly relates to an alcohol precipitation device capable of recovering ethanol. Background Technique

[0002] The chondroitin sulfate alcohol precipitation device is a professional device for separating and precipitating chondroitin sulfate from a specific solution. At present, there are many disadvantages in that ethanol cannot be recovered in the chondroitin sulfate alcohol precipitation device. First of all, the large amount of un-recovered ethanol directly leads to a significant increase in production costs. Since ethanol is a commonly used solvent and a large amount is used in the alcohol precipitation process, the inability to recover means that new ethanol needs to be invested in each operation, resulting in a significant economic burden over the long term. The reason for this disadvantage lies in the limitations of the device design, which fails to consider the function of ethanol recovery. The conventional coping method is to try to control the ethanol usage as much as possible, but this has drawbacks and may lead to poor alcohol precipitation effect, affecting the purity and yield of chondroitin sulfate. Secondly, the non-recovery of ethanol also causes environmental pollution. The random discharge of ethanol disrupts the ecological balance and causes harm to the soil, water sources, etc. This is due to the lack of an effective recovery mechanism. The usual coping strategy is to strengthen environmental protection treatment, but this not only increases the treatment cost, but also has limited effects and cannot fundamentally solve the problem of ethanol discharge. Moreover, the waste of ethanol also limits the expansion of production scale because it is difficult to increase production due to high costs. The reason is that ethanol resources are not effectively utilized, so a new structure needs to be proposed to solve the above technical problems. Content of the Utility Model

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] Please refer to Figures 1 to 2, the present utility model provides a technical solution: an ethanol precipitation device capable of recovering ethanol, comprising: an ethanol precipitation tank 100 and a recovery assembly. A tank cover 200 is installed on the upper surface of the ethanol precipitation tank 100. A stirring assembly is installed on the upper surface of the tank cover 200. A feed pipe 210 is installed on the upper surface of the tank cover 200. A filter screen is installed inside the ethanol precipitation tank 100. An observation window 150 and a tank door 140 are hermetically hinged on the outer surface of the ethanol precipitation tank 100. A discharge pipe 130 is installed on the lower surface of the ethanol precipitation tank 100. A recovery assembly is installed on the outer surface of the ethanol precipitation tank 100. The recovery assembly includes: a recovery pipe 410, an evaporation chamber 400, a connecting pipe, a condensation chamber 420, and a discharge pipe. A connecting pipe is installed between the evaporation chamber 400 and the condensation pipe. The discharge pipe 130 is installed with a recovery pipe 410 through a pump. One end of the recovery pipe 410 away from the discharge pipe 130 is connected to the evaporation chamber 400.

[0021] Please refer to Figure 1 , Figure 2 , as the first embodiment of the present utility model: The tank cover 200 is fixed on the upper surface of the ethanol precipitation tank 100 through a fixing member. The stirring assembly includes: a stirring motor 300, a rotating shaft 310, a connecting rod 320, and a scraping plate 330. Two feed pipes 210 are symmetrically installed on the upper surface of the tank cover 200. A stirring motor 300 is installed on the upper surface of the tank cover 200;

[0022] The output shaft of the stirring motor 300 is installed with a rotating shaft 310 through a coupling. A connecting rod 320 is installed on the outer surface of the rotating shaft 310. One end of the connecting rod 320 away from the rotating shaft 310 is installed with a scraping plate 330. The side of the scraping plate 330 away from the connecting rod 320 abuts against the inner wall of the tank body of the ethanol precipitation tank 100. A filter screen is installed below the stirring assembly;

[0023] When in use, the user discharges the chondroitin sulfate solution and the ethanol solution into the alcohol precipitation tank 100 through the feed pipe 210. Then, after the discharge is completed, the user can start the stirring motor 300 to drive the rotating shaft 310 to rotate, thereby driving the connecting rod 320 and the scraper 330 to rotate, and performing alcohol precipitation operation on the chondroitin sulfate solution inside the alcohol precipitation tank 100. After the stirring is completed, since the diameter of the alcohol precipitate is larger than the diameter of the filter mesh holes, the alcohol precipitate will not fall below the filter screen. At this time, the remaining un-precipitated ethanol will fall from the sieve to the bottom inside the alcohol precipitation tank 100, and then be discharged through the discharge pipe 130. Then, the un-precipitated ethanol is recovered by the recovery component. When the alcohol precipitate needs to be taken out, the user only needs to open the door 140 to collect the alcohol precipitate on the surface of the filter screen. Since the stirring motor 300 drives the rotating shaft 310 to rotate, the connecting rod 320 and the scraper 330 move accordingly, which can make the chondroitin sulfate solution and ethanol fully contact and mix, helping to ensure that the alcohol precipitation reaction proceeds uniformly in the entire solution system and avoiding inconsistent alcohol precipitation effects caused by local concentration differences.

[0024] Please refer to Figure 1 、 Figure 2 As the second embodiment of the present utility model: The bottom inside the alcohol precipitation tank 100 is in a conical structure. Four support legs 110 are installed on the lower side surface of the alcohol precipitation tank 100. A discharge pipe 130 is installed at the central position of the lower side surface of the alcohol precipitation tank 100. A pump is installed at one end of the discharge pipe 130 away from the alcohol precipitation tank 100.

[0025] A recovery pipe 410 is installed at the outlet of the pump. The recovery pipe 410 is in a U-shaped structure. An evaporation chamber 400 and a condensation chamber 420 are installed on the left side of the outer surface of the alcohol precipitation tank 100. One end of the recovery pipe 410 away from the pump is connected to the central position of the lower side surface of the evaporation chamber 400. An electric heating element is installed inside the evaporation chamber 400.

[0026] A connecting pipe is installed on the upper side surface of the evaporation chamber 400. The upper end of the connecting pipe is connected to the lower side surface of the condensation chamber 420. A discharge pipe is installed on the lower side surface of the condensation chamber 420. A condenser is installed inside the condensation chamber 420. A door panel is installed on the outer surface of the evaporation chamber 400.

[0027] During use, after the ethanol that has not been completely precipitated by alcohol is discharged through the discharge pipe 130, the user starts the pump at this time, so that the pump sucks the ethanol into the inside of the recovery pipe 410, and then sucks the ethanol inside the recovery pipe 410 into the evaporation chamber 400. At this time, the user can start the electric heating element inside the evaporator. The ethanol sucked into the evaporation chamber 400 will be heated by the electric heating element and vaporized. Then the vaporized ethanol will enter the condensation chamber 420 through the connecting pipe. Then start the condenser inside the condensation chamber 420 to condense the vaporized ethanol into a liquid state, and then discharge the liquefied ethanol through the discharge pipe for recycling. After the evaporation chamber 400 has been used for a period of time, the user can open the door panel on the surface of the evaporation chamber 400 to clean the impurities inside the evaporation chamber 400 to avoid affecting subsequent ethanol evaporation operations. Since ethanol is a commonly used organic solvent, recycling and reusing ethanol through the recovery component can reduce the usage of new ethanol, thereby significantly reducing the solvent cost in the production process, realizing the recycling of ethanol resources, improving the utilization efficiency of resources, and conforming to the concept of sustainable development.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
