Technical Field

[0001] The utility model relates to the field of chemical industry, in particular to a carbon dioxide supercritical extraction gas disperser. Background Art

[0002] Supercritical carbon dioxide extraction is a technology that uses carbon dioxide in a supercritical state as a solvent to extract substances. This method is widely used in the food, pharmaceutical, cosmetics, fragrance and other industries to extract plant essential oils, natural pigments, fatty acids, caffeine and other ingredients. A gas diffuser is a device used to evenly disperse gas into liquids or other gases. It is widely used in many fields, including chemical industry, biotechnology, water treatment, laboratory research, etc.

[0003] Existing equipment can only extract relatively coarse materials. If relatively fine materials are produced, the carbon dioxide fluid will carry the materials out of the material basket and into the carbon dioxide pipeline, causing blockage of the carbon dioxide pipeline. In addition, the existing equipment only separates the materials in the material basket once in the state of carbon dioxide fluid, resulting in low production efficiency.

[0004] Therefore, it is necessary to design a carbon dioxide supercritical extraction gas disperser that can evenly feed the carbon dioxide fluid, improve the extraction efficiency and production efficiency, and can reflux the fluid under the action of the conical part for secondary extraction, prevent the material from being carried out, and improve the extraction effect.

[0006] The technical implementation scheme of the utility model is: a carbon dioxide supercritical extraction gas diffuser, including a mounting tube, a first orifice plate, a filter screen, a support column, a baffle, a second orifice plate and a fixing assembly, the first orifice plate is connected to the inner side of the middle part and the inner side of the lower part of the mounting tube, the filter screen is connected to the lower side of the first orifice plate, a plurality of support columns are connected between the first orifice plates, the upper side of the support columns is connected to the baffle, the baffles are in contact with the mounting tube, the second orifice plate is placed between the baffles, and the baffles are provided with a fixing assembly.

[0007] As a preferred technical solution of the present invention, the mounting tube is made of a transparent material.

[0009] As a preferred technical solution of the present invention, a plurality of tapered parts are provided on the upper side of the second orifice plate.

[0010] As an optimal technical solution of the present invention, the fixing assembly includes a telescopic rod, a spring and a pressure plate. The baffles are connected to the telescopic rod, and springs are connected between the fixed end and the telescopic end of the telescopic rod.

[0011] As a preferred technical solution of the present invention, it also includes a connecting flange, and the outer sides of the upper and lower parts of the installation pipe are both connected to the connecting flange.

[0012] The utility model has the following advantages: 1. The utility model is connected to the feed port of the extraction tank through the upper connecting flange. By adding carbon dioxide fluid into the feed pipe, the carbon dioxide fluid enters the installation pipe, flows through the first hole plate, the filter screen and the second hole plate, and then flows into the extraction tank to extract the material, thereby being able to evenly feed the carbon dioxide fluid and improve the extraction efficiency and production efficiency.

[0013] 2. The utility model places the device in the extraction tank, so that the carbon dioxide can achieve a reflux effect under the action of the conical member, thereby causing the carbon dioxide fluid to reflux under the action of the conical member on the second hole plate for secondary extraction, thereby facilitating secondary extraction of the material, reducing the pressure of the carbon dioxide fluid when it is discharged from the material basket, preventing the material from being carried out, and improving the extraction effect.

[0014] 3. The utility model makes the second orifice plate contact with the baffle, then reversely rotates the pressure plate to reset, and then releases the pressure plate, the spring rebounds, and the telescopic rod contracts and recovers, so that the pressure plate contacts the second orifice plate, thereby fixing the second orifice plate and preventing the second orifice plate from falling when the carbon dioxide fluid flows.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] A carbon dioxide supercritical extraction gas diffuser, such as Figure 1-Figure 3 As shown, it includes a mounting tube 1, a connecting flange 2, a first hole plate 3, a filter screen 4, a support column 5, a baffle 6, a telescopic rod 7, a spring 70, a pressure plate 8 and a second hole plate 9. The mounting tube 1 is made of transparent material for easy observation of the internal situation. The outer sides of the upper and lower parts of the mounting tube 1 are connected with a connecting flange 2 for easy external connection to the pipeline. The inner side of the middle part and the inner side of the lower part of the mounting tube 1 are connected with the first hole plate 3. The lower side of the first hole plate 3 is connected with the filter screen 4. Four supporting columns 5 are connected between the first hole plates 3. The upper sides of the supporting columns 5 are connected with baffles 6. The baffles 6 are in contact with the mounting tube 1. The baffles 6 are connected with telescopic rods 7. The fixed end and the telescopic end of the telescopic rod 7 are connected with springs 70. The telescopic end of the telescopic rod 7 is rotatably connected with a pressure plate 8. The second hole plate 9 is placed between the baffles 6. The pressure plate 8 is in contact with the second hole plate 9. The first hole plate 3 and the second hole plate 9 have the same shape. Twelve cones are provided on the upper side of the second hole plate (9) for easy backflow.

[0021] When the extracted components need to be extracted by supercritical carbon dioxide extraction, this device can be used. The device is driven to the place where the extracted components need to be extracted, so that the connecting flange 2 at the bottom of the mounting tube 1 is connected to the feed pipe. The mounting tube 1 is made of transparent material, which is convenient for observing the internal situation. Then, the pressure plate 8 is pulled to move and rotate, so that the telescopic rod 7 is extended and the spring 70 is stretched. Then, the second hole plate 9 is brought into contact with the baffle 6, and then the pressure plate 8 is rotated in the opposite direction to reset. Then, the pressure plate 8 is released, the spring 70 rebounds, and the telescopic rod 7 shrinks and recovers, so that the pressure plate 8 is brought into contact with the second hole plate 9, thereby fixing the second hole plate 9 to prevent the second hole plate 9 from falling when the carbon dioxide fluid flows. Then, the upper connecting flange 2 is connected to the feed port of the extraction tank. Then, by adding carbon dioxide fluid into the feed pipe, the carbon dioxide fluid enters the installation pipe 1, flows through the first hole plate 3, the filter screen 4 and the second hole plate 9, and then flows into the extraction tank to extract the material. The first hole plate 3 and the second hole plate 9 have the same shape, so that the carbon dioxide fluid can be fed evenly, improving the extraction efficiency and production efficiency. At the same time, the device can be placed in the extraction tank, and the carbon dioxide can achieve a reflux effect under the action of the tapered member, so that the carbon dioxide fluid refluxes under the action of the tapered member on the second hole plate 9 for secondary extraction, which facilitates the secondary extraction of the material, reduces the pressure of the carbon dioxide fluid when it is discharged from the material basket, prevents the material from being brought out, and improves the extraction effect.
