Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a separation and extraction device for black tea extract as Figures 1-3 shown, including a base 1 and a barrel body 11 installed on the upper side of the base 1;

[0025] A feeding port 4 is provided on the upper side of the barrel body 11 to add a mixture of tea powder and extractant into the interior of the barrel body 11;

[0026] The inner wall of the lower end of the barrel body 11 is drivingly connected to a fixed seat 12;

[0027] The upper outer wall of the fixed seat 12 is fixedly connected with a separator 8. The circular inner walls of the separator 8 are respectively provided with an ultrafiltration cylinder a17 and an ultrafiltration cylinder b18 to block the tea powder in the mixture of tea powder and extractant. Drainage ports 24 are fixedly connected to the inner parts of the left and right outer walls of the barrel body 11 to discharge the extractant outward. A clamping tooth 13 is fixedly connected between the left and right outer walls of the fixed seat 12 near the lower side. A driving motor 16 is arranged on the left side of the right inner wall of the base 1. The driving motor 16 is electrically connected to an external power supply. The upper outer wall of the driving motor 16 is fixedly connected with a driving tooth 14 to engage with the clamping tooth 13 to drive the fixed seat 12 to rotate. A discharge port 3 is formed in the inner part of the lower outer wall of the barrel body 11 to discharge the tea powder. When separating and extracting the tea powder and the extractant, first, the mixture of tea powder and extractant is introduced into the separator 8 inside the barrel body 11 from the feeding port 4. Subsequently, the driving motor 16 is started, and the driving tooth 14 is controlled to drive the clamping tooth 13 to rotate, thereby driving the fixed seat 12 and the separator 8 on its upper end to rotate. During the rotation process, the mixture of tea powder and extractant is continuously added. The separator 8 rotating at a high speed will drive the mixture of tea powder and extractant to form a vortex and separate the mixture of tea powder and extractant through the ultrafiltration cylinder a17 and the ultrafiltration cylinder b18. The separated extractant is discharged from the drainage port 24, and the tea powder is subsequently discharged outward from the discharge port 3;

[0028] Scrapers 10 are respectively arranged on the circular inner wall of the ultrafiltration cylinder a17 and near the left and right sides to scrape off the tea powder adhering to the inner wall of the ultrafiltration cylinder a17. Scraping teeth 19 are fixedly connected to one end of each of the two scrapers 10 that fits the inner wall of the ultrafiltration cylinder a17. During the high-speed rotation of the separator 8, the scraping teeth 19 and the scrapers 10 that fit the inner wall of the ultrafiltration cylinder a17 can scrape off the tea powder adhering to the inner wall of the ultrafiltration cylinder a17, avoiding the situation where the tea powder accumulates on the inner wall of the ultrafiltration cylinder a17 and causes the slow flow rate of the extractant.

[0029] As Figure 3 shown, arc angles 20 are respectively arranged on the side of each of the two scrapers 10 close to the inner wall of the ultrafiltration cylinder a17 and in front of the scraping teeth 19 to guide the moving direction of the scraped tea powder. Guide blocks 21 are fixedly connected to the front outer walls of the two scrapers 10 to guide the scraped tea powder to the center of the separator 8.

[0030] After the scraping teeth 19 scrape off the tea powder on the inner wall of the ultrafiltration cylinder a17, the tea powder will be guided to the guide block 21 through the arc angle 20 to transfer the tea powder.

[0031] As Figure 3 and Figure 4As shown, connection blocks 22 are fixedly connected to the outer walls of the upper ends of both scraping plates 10. A guiding ring 23 is fixedly connected near the lower side between the two scraping plates 10 to guide the tea powder into the discharge port 3. The guiding ring 23 is inclined inward, and the two scraping plates 10 and the guiding ring 23 are fixedly connected by welding.

[0032] The positions of the two scraping plates 10 are restricted by fixedly connecting through the connection blocks 22 and the guiding plate 6 inside the barrel body 11. After the tea powder is scraped off and guided by the guiding block 22, it will fall into the guiding ring 23, and the tea powder is guided to the upper side of the discharge port 3, waiting for subsequent cleaning.

[0033] As Figure 1 shown, a top cover 5 is provided on the outer wall of the upper end of the barrel body 11 to restrict the position of the feeding port 4. Guiding plates 6 are fixedly connected to the inner walls of the left and right ends of the barrel body 11 to guide the tea powder and extractant mixture into the separator 8. A fixed plug 2 is provided inside the discharge port 3 to control the opening and closing of the discharge port 3. A fixing frame 15 is fixedly connected between the outer wall of the right end of the driving motor 16 and the inner wall of the right end of the base 1 to restrict the position of the driving motor 16.

[0034] The position of the feeding port 4 is restricted by the top cover 5. At the same time, the inside of the barrel body 11 and the separator 8 can be cleaned and replaced by opening the top cover 5. The fixed plug 2 can be removed by rotating it counterclockwise, and at this time, the tea powder accumulated on the upper side of the discharge port 3 can be discharged. Rotating the fixed plug 2 clockwise into the discharge port 3 can block the discharge port 3 to prevent the leakage of the tea powder and extractant mixture during the separation process.

[0035] As Figure 1 shown, drain pipes 9 are fixedly connected to the inner walls of the left and right ends of the barrel body 11. The outer wall of the right end of one of the two drain pipes 9 is fixedly connected with a water inlet 7 to convey cleaning liquid into the drain pipe 9. A plurality of nozzles are arranged at equal distances from top to bottom on the opposite sides of the two drain pipes 9 to spray the cleaning liquid. A driving shaft is arranged between the driving motor 16 and the driving gear 14.

[0036] When separating the mixture of tea powder and extractant after completion, pressurized cleaning liquid can be added to the water inlet 7. The cleaning liquid will be guided through the drain pipe 9 and sprayed out from the nozzles to clean the ultrafiltration cylinder a17 and ultrafiltration cylinder b18 in the separator 8. At this time, the drain port 24 is connected to the sewage discharge pipe, so that the cleaning liquid is discharged out from the drain port 24.

[0037] The implementation principle of this embodiment is as follows: when separating and extracting tea powder and extractant, first, the mixture of tea powder and extractant is introduced into the separator 8 inside the barrel body 11 from the feeding port 4. Subsequently, the driving motor 16 is started, and the driving gear 14 is controlled to drive the engaging teeth 13 to rotate, thereby driving the fixing seat 12 and the separator 8 at its upper end to rotate. During the rotation process, the mixture of tea powder and extractant is continuously added. The high-speed rotating separator 8 will drive the mixture of tea powder and extractant to form a vortex and separate the tea powder and extractant mixture through the ultrafiltration cylinder a17 and the ultrafiltration cylinder b18. The separated extractant is discharged from the drain port 24, and the tea powder is subsequently discharged outward from the discharge port 3. During the high-speed rotation of the separator 8, the scraping teeth 19 and the scraping plate 10 attached to the inner wall of the ultrafiltration cylinder a17 can scrape off the tea powder adhering to the inner wall of the ultrafiltration cylinder a17, preventing the situation where the tea powder accumulates on the inner wall of the ultrafiltration cylinder a17 and causes the slow flow rate of the extractant.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. 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.
