Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device for aged tea extract. Background Art

[0002] Aged tea leaf extract is a natural extract with multiple uses and functions. Aged tea leaf extract is rich in antioxidants such as tea polyphenols and catechins, which can scavenge free radicals, reduce oxidative stress, delay aging, and prevent chronic diseases. Because the extract contains many unnecessary impurities, it must be filtered to obtain the extract of the required purity.

[0003] When filtering the extract of old tea leaves, since the extract contains more impurities, and the particles and types of the impurities are different, when using the filter to filter the extract, the impurities in the extract will adhere to the filter. In the existing structure, a scraper pair is often used to scrape the filter in real time to extend the service life of the filter and reduce the impact of impurity blockage on the filtering efficiency. However, the scraper pair can only clean the impurities on the surface of the filter that are easy to clean, and the scraper pair will also be attached with impurities when working. Therefore, this method has a poor cleaning effect on the filter and has a greater impact on the filtering efficiency.

[0004] Based on the above situation, it is necessary to design a filtering device for old tea extract to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0022] Reference Figure 1-Figure 5 As shown, a filtering device for aged tea extract comprises a three-way valve body 1, to which an input pipe 2 and two output pipes 3 are connected, and further comprises a tank body 4, a water inlet mechanism and a water outlet mechanism respectively connected to the output ends of the two output pipes 3. A plurality of filter screen members 5 are arranged in the tank body 4, and scrapers 6 driven to rotate by a driving member are arranged on the upper and lower sides of the filter screen member 5; the water inlet mechanism is used to transport clean water into the tank body 4 and accelerate the flow rate of the clean water in the tank body 4; the water outlet mechanism is used to discharge the clean water containing impurities in the tank body 4. When in use, the three-way valve body 1 is activated to connect one of the output pipes 3 with the input pipe 2. At this time, the extract will be introduced into one of the tank bodies 4 for filtering treatment. When the tank body 4 has been filtering for a period of time, the three-way valve body 2 is activated to connect the other output pipe 3 with the input pipe 2. At this time, the other tank body 4 performs the filtering operation, and the previously used tank body 4 starts the self-cleaning operation.

[0023] During cleaning, the water inlet mechanism is first used to introduce external clean water into the tank body 4, so that the interior of the tank body 4 is filled with clean water and is in a flowing state. Then, the driving member is used to drive the scraper 6 to rotate and scrape off the impurities on the surface of the filter element 5. Under the impact of the clean water, the impurities will be mixed into the clean water. Then, the water outlet mechanism is used to discharge the clean water containing impurities from the tank body 4. After the tank body 4 is cleaned, the three-way valve body 1 is started to connect the tank body 4 with the input end and perform the filtering operation. Then, the other tank body 4 is cleaned. This cycle is repeated, and the tank body 4 is cleaned without delaying the filtering operation. During cleaning, the impurities in the tank body 4 can be removed, thereby improving the cleaning degree of the filter element 5 and improving the filtering effect of the tank body 4 on the extract.

[0024] Among them, the driving part includes a rotating shaft 8 and a motor 7 arranged on the tank body 4. One end of the rotating shaft 8 passes through and rotates on the top of the tank body 4, and is connected to the output end of the motor 7. The other end of the rotating shaft 8 passes through several filter members 5 and is connected to the scraper 6. When in use, start the motor 7, the motor 7 will drive the rotating shaft 8 to rotate, and then drive the scraper 6 connected to the rotating shaft 8 to rotate with the central axis of the rotating shaft 8 as the center of the circle, which will scrape off the impurities attached to the filter member 5 so that the impurities will no longer continue to adhere to the filter member 5.

[0025] Furthermore, the water inlet mechanism includes a water inlet pipe 9, a plurality of nozzles 10 connected to the water inlet pipe 9, and a water pump 11 arranged on the water inlet pipe 9. The output ends of the plurality of nozzles 10 extend to the interior of the tank body 4. The water inlet pipe 9 is provided with a three-way valve body 2 12 and a three-way valve body 3 14. The three-way valve body 2 12 is connected to a water diversion pipe 13, and the three-way valve body 3 14 is connected to a drainage pipe 15. The three-way valve body 2 12 and the three-way valve body 3 14 are respectively located at the input and output ends of the water pump 11. When the scraper 1 6 scrapes away the impurities attached to the filter element 5, the three-way valve body 2 12 is opened to connect the water diversion pipe 13 to the water inlet pipe 9, receive the water source outside the drinking water pipe, and introduce clean water into the water inlet pipe 9. Under the action of the water pump 11, the clean water is sent to the plurality of nozzles 10 in an accelerated manner, and then sent into the tank body 4 by the plurality of nozzles 10.

[0026] Several filter elements 5 will divide the tank body 4 into several chambers. In order to ensure that the clean water can be quickly filled in the tank body 4, several nozzles 10 will be set in each chamber. When the nozzle 10 sprays water, the water flow impact force formed at its output end will also act on the filter element 5 at an oblique angle, and then cooperate with the scraper 6 to enhance the cleaning effect of impurities on the filter element 5. After a certain volume of clean water is injected into the tank body 4, the water flow sprayed by the nozzle 10 will cause the clean water in each chamber to be in a flowing state, carrying the impurities scraped off from the filter element 5 by the scraper 6 to flow, preventing the impurities from continuing to settle on the filter element 5 and attaching to it again.

[0027] Furthermore, the water outlet mechanism includes several water outlet pipes 16, a water conduit 17 connected to the several water outlet pipes 16, and a water pump 170 arranged on the water conduit 17. The water outlet pipe 16 is provided with a solenoid valve 18. After the scraper 6 in the tank body 4 has been operating for a period of time, the solenoid valve 18 is opened to connect the water outlet pipe 16 with the water conduit 17. Then, under the action of the water pump 170, the clean water containing impurities inside the tank body 4 is pumped out from the tank body 4, and then the clean water will flow out along the water conduit 27 and its output end. During this period, the three-way valve body 12 will close the connection between the water diversion pipe 13 and the water inlet pipe 9, so that the input end and the output end of the water inlet pipe 9 are connected, so that the water inlet pipe 9 no longer receives water from the external source at this time.

[0028] Next, a liquid outlet cavity 19 is formed between the bottom of the tank body 4 and the filter element 5 near the bottom of the tank body 4. In order to clean the liquid outlet cavity 19 between the filter element 5 and the bottom of the tank body 4, a scraper 20 is provided in the liquid outlet cavity 19. The scraper 20 is connected to the end of the rotating shaft 8 away from the top of the tank body 4. The bottom of the tank body 4 is connected to a liquid outlet pipe 21, and a three-way valve body 4 is provided on the liquid outlet pipe 21. The three-way valve body 4 is connected to a sewage pipe 23, and a water pump 3 24 is provided on the sewage pipe 23. When the water pump 2 170 extracts clean water from the inside of the tank body 4, a suitable time period is selected and the three-way valve body 4 is rotated to connect the liquid outlet pipe 21 with the sewage pipe 23. The clean water containing impurities in the liquid outlet cavity 19 is discharged through the water pump 3 24.

[0029] Furthermore, in order to reduce the waste of water resources, a filter tank 25 is provided below the tank body 4, and a movable filter screen 26 is provided in the filter tank 25. The movable filter screen 26 is movably installed in the filter tank 25, which is convenient for removal at any time. Since the filter tank 25 has a small volume, it is also convenient to remove it. The input end and the output end of the filter tank 25 are respectively connected to the water pipe 2 27 and the water pipe 3 28, and the output end of the sewage pipe 23 and the output end of the water pipe 1 17 are both connected to the input end of the water pipe 2 27, and the output end of the water pipe 3 28 is connected to the input end of the water inlet pipe 9. The water pipe 2 27 discharges the water from the water pipe 1 17 and the sewage pipe 23. The water is introduced into the filter tank 25, filtered by the movable filter 26, and then discharged through the water pipe three 28. The impurities in the clean water at this time will be filtered by the movable filter 26, and the clean water is cleaned. The clean water after the cleaning treatment will flow into the output end position of the water inlet pipe 9, and then under the action of the water pump 11, the clean water is transported to the position of the nozzle 10. This cycle will clean the impurities inside the tank body 4. Finally, the three-way valve body three 14 is started to discharge the last water flow along the drain pipe 15, and then the three-way valve body four 22 is started to make the output end of the liquid outlet pipe 21 connected to the inside of the tank body 4 again.
