[0018] Please see Figure 1-3 This utility model provides an embodiment of a tea beverage processing impurity removal device, including a storage tank 1, a fixed top cover 2 installed on the top of the storage tank 1, and a filter cylinder 3 for filtration. Several support legs 7 are fixed to the bottom of the outer peripheral wall of the storage tank 1. The bottom of the storage tank 1 is funnel-shaped, and the bottom of the storage tank 1 is provided with an outlet 101 for discharging the internally filtered tea beverage. A valve (not shown in the figure) is installed on the outlet 101. The storage tank 1 can temporarily store the filtered tea beverage. In order to facilitate observation of the liquid level, a transparent observation window can be provided on the storage tank 1, or a liquid level sensor can be installed inside.

[0019] In this embodiment, a flange ring 102 is horizontally provided at the top edge of the liquid storage tank 1, and the flange ring 102 is detachably connected to the fixed top cover 2 by bolts, which makes it convenient to remove the fixed top cover 2 to clean and maintain the inside of the liquid storage tank 1, making it safer and more hygienic.

[0020] Two filter cartridges 3 are provided, one for filtration and one for cleaning, reducing downtime. A movable top cover 4 is located at the top of the fixed top cover 2. All filter cartridges 3 are open-top cylindrical structures. Several filter holes are provided on the side walls of the filter cartridges 3, and the hole diameter can be set as needed. After the beverage enters the filter cartridge 3 for filtration, tea leaves and other impurities remain inside. The filter cartridge 3 can be removed for cleaning. A limit stop 301 is horizontally provided at the top edge of the filter cartridge 3. A through-hole is provided on the fixed top cover 2 to accommodate the bottom end of the filter cartridge 3. An opening extending into the liquid storage tank 1 has a downwardly recessed positioning groove 201 at its edge that matches the limiting baffle 301. After the filter cartridge 3 is inserted into the liquid storage tank 1, the limiting baffle 301 abuts against the inside of the positioning groove 201, and the movable top cover 4 abuts against the top of the limiting baffle 301, thus limiting the filter cartridge 3. In this embodiment, the limiting baffle 301 is annular. Furthermore, to prevent the filter cartridge 3 from rotating during filtration, the limiting baffle 301 can also be set as a square ring or other structure (not shown in the figure).

[0021] The movable top cover 4 is provided with a liquid inlet 401 and a maintenance port 402 corresponding to the two filter cartridges 3. The inner diameter of the maintenance port 402 is not less than the outer diameter of the limiting stop 301, so that the filter cartridge 3 can be pulled out of the maintenance port 402 for cleaning. The inner diameter of the liquid inlet 401 is smaller than the inner diameter of the filter cartridge 3 to prevent the filter cartridge 3 from moving up and down. The liquid inlet 401 can be connected to the tea beverage to be filtered through a hose, and the tea beverage to be filtered is passed into the interior of the filter cartridge 3 for filtration. The movable top cover 4 is adjustablely connected to the fixed top cover 2, specifically by rotation, for exchanging the positions of the liquid inlet 401 and the maintenance port 402 with the two filter cartridges 3. In this embodiment, the liquid inlet 401 and the maintenance port 402 are located on both sides of the radial direction of the movable top cover 4. By rotating the movable top cover 4 as a whole by 180 degrees, the positions of the filter cartridges 3 corresponding to the liquid inlet 401 and the maintenance port 402 can be exchanged. After working for a period of time, the filter cartridges 3 can be replaced for filtration, and the filter cartridges 3 containing impurities can be taken out for cleaning.

[0022] The maintenance port 402 is provided with a sealing cap 5 for sealing. Specifically, the inner peripheral wall of the maintenance port 402 is provided with an internal thread, and the outer peripheral wall of the sealing cap 5 is provided with an external thread that matches the internal thread of the maintenance port 402. When the sealing cap 5 is inserted to the lowest end of the maintenance port 402, the bottom end of the sealing cap 5 abuts against the top edge of the filter cartridge 3 to limit the filter cartridge 3. After the filter cartridge 3 is removed, the liquid storage tank 1 can also be sealed.

[0023] The movable top cover 4 is provided with a locking structure 6 for fixing it. Specifically, the movable top cover 4 is a circular plate structure. The fixed top cover 2 has an annular groove 202 that is adapted to the movable top cover 4 at its edge. The movable top cover 4 can rotate freely inside the annular groove 202. The locking structure 6 includes a threaded post 601 that is vertically fixed at the edge of the movable top cover 4. The top of the annular groove 202 is provided with a limiting slide hole 602 that accommodates the threaded post 601 to rotate around the center of the movable top cover 4. The limiting slide hole 602 is an arc groove that is concentric with the annular groove 202 and has an angle of 180 degrees. The threaded post 601 passes through the limiting slide hole 602 and is threadedly connected to a locking nut 603. When the threaded post 601 rotates to the limit position at both ends of the limiting slide hole 602, the two filter cartridges 3 correspond one-to-one with the liquid filling port 401 and the maintenance port 402, respectively, for convenient use.

[0024] Working principle: The liquid inlet 401 is connected to the tea beverage to be filtered through a hose. The tea beverage enters the interior of the filter cartridge 3 and is filtered by the filter cartridge 3. Tea residue and other impurities remain inside the filter cartridge 3, and the clarified tea beverage enters the storage tank 1 for storage. Finally, it is discharged through the liquid outlet 101. After working for a period of time, a lot of impurities adhere to the inner wall of the filter cartridge 3. Loosen the locking nut 603 and rotate the threaded post 601 180 degrees around the center of the movable top cover 4 to the limit position of the other end of the limit sliding hole 602. Then tighten the locking nut 603 to fix it. At this time, the liquid inlet 401 and the maintenance port 402 are switched. The liquid inlet 401 is rotated to the top of another filter cartridge 3 for liquid addition and filtration. Open the sealing cover 5 and the filter cartridge 3 containing impurities can be completely pulled out from the liquid inlet 401 for cleaning to avoid contaminating the tea beverage inside the storage tank 1.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
