Technical Field

[0001] This utility model relates to the technical field of tea filtration equipment, and in particular to a multi-stage filtration component and a cold-brewed tea clarification device. Background Technology

[0002] Cold-brewed tea stands out in the tea beverage industry due to its method of brewing with cold water. Cold water steeping reduces the dissolution of bitter and astringent substances in tea leaves at low temperatures, accelerates the extraction of umami substances, resulting in a sweeter taste. At the same time, it reduces the loss of nutrients such as vitamin C and tea polyphenols, preserving the natural flavor and nutritional components of the tea leaves.

[0003] In the tea beverage market, clarity and transparency are important indicators of quality, and cold-brewed tea drinks with high transparency are more favored by consumers and distributors. However, existing cold-brewed tea filtration and clarification equipment has a complex internal structure. The filter cartridge, as a key component, needs to be replaced regularly to ensure filtration effectiveness. However, the complex structure makes the filter cartridge replacement process cumbersome, time-consuming, and increases the difficulty of operation, causing many inconveniences for users.

[0004] To address the aforementioned issues, this utility model document proposes a multi-stage filtration component and a cold-brew tea clarification device. Utility Model Content

The filter element, as a key component, needs to be replaced regularly to ensure the filtration effect. However, the complex structure makes the filter element replacement process cumbersome, which not only consumes time but also increases the difficulty of operation, causing many inconveniences to users.

[0006] This utility model provides the following technical solution:

[0007] A multi-stage filtration assembly and a cold-brew tea clarification device, comprising:

[0008] A filter canister has two symmetrically arranged sliding grooves on its inner wall. A corresponding vertical rod is slidably arranged in the sliding groove. A horizontal bar for serving as a handle is fixedly arranged at the top of the vertical rod. Two annular frames are welded and fixed between the two vertical rods. A corresponding fixing ring is snapped onto the annular frame. A first filter element and a second filter element are fixedly arranged sequentially from top to bottom on the inner wall of the two fixing rings. A discharge pipe is connected to the center of the bottom of the filter canister. A corresponding discharge valve is arranged on the discharge pipe. A fine filter cloth is detachably installed at the bottom end of the discharge pipe.

[0009] The filter can is provided with a matching can lid at the top opening of the can, and a stop block is fixedly provided at the bottom of the can lid to abut against the top of the crossbar. The filter can and the can lid are fixed together by a fastener assembly that is easy to open and close.

[0010] In one possible design, two pre-drilled holes on the fixing ring are provided with corresponding bolts, and the ends of the bolts are threadedly connected to the corresponding threaded holes on the ring frame.

[0011] In one possible design, the bottom end of the discharge pipe is threaded with a hollow cap, and the fine filter cloth is filled inside the hollow cap and wraps around the outlet of the discharge pipe.

[0012] In one possible design, the fastener assembly includes U-shaped hooks welded and fixed to the outer wall of the can lid in a circular array, and a handle for engaging with the corresponding U-shaped hooks is provided on the upper edge of the outer wall of the filter can, with the seat plate of the handle welded and fixed to the outer wall of the filter can.

[0013] This utility model also provides a cold brew tea clarification device, including the multi-stage filtration assembly described in any one of the above, and two vibration motors, which are fixedly installed on one side of the corresponding mounting base on the outer wall of the filter tank.

[0014] In one possible design, a base is welded and fixed to the bottom of the outer wall of the filter tank, and a hollow frame that contacts the ground is provided below the base. Springs for reducing vibration transmission are arranged in a circular array between the base and the hollow frame. The fixing seats at both ends of the springs are fixedly connected to the bottom of the base and the top of the hollow frame, respectively.

[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0016] The working principle and usage process of this technical solution are as follows:

[0017] The following is the working process of this multi-stage filtration assembly and cold brew tea clarification equipment:

[0018] When installing the filter elements, fix the first and second filter elements to the inner walls of the two fixing rings respectively, and install them from top to bottom. Attach the fixing rings to the ring frame and thread them through the pre-drilled holes on the fixing rings to the corresponding threaded holes on the ring frame to securely connect the fixing rings and the ring frame. Then, place the ring frame with the filter elements installed into the groove on the inner wall of the filter tank using a vertical rod, allowing the vertical rod to slide in the groove until it contacts the bottom. Then, place the tank lid at the top opening of the filter tank, ensuring the bottom abutment of the lid abuts against the top of the corresponding horizontal bar. Secure the filter tank to the lid using the snap fastener assembly, i.e., fasten the U-shaped hook on the outer wall of the lid with the buckle on the upper edge of the outer wall of the filter tank. When installing the fine filter cloth, fill the hollow cap with the fine filter cloth and wrap it around the outlet pipe opening, then thread the hollow cap to the bottom end of the outlet pipe.

[0019] When in use, the feed pipe at the top of the can lid receives the filtered and clarified cold-brewed tea liquid through the hose. After the power of the vibration motor is turned on, the vibration motor drives the filter can to vibrate. After the tea liquid enters the can, it first passes through the first filter element for preliminary filtration to remove larger particles of impurities. Then it passes through the second filter element for further filtration to remove smaller impurities. The vibration of the vibration motor can make the tea liquid pass through the filter element better, improving the filtration efficiency. After opening the discharge valve on the discharge pipe, the tea liquid filtered by the two-stage filter element flows out through the discharge pipe and then passes through the fine filter cloth for a final filtration to obtain a clear and transparent cold-brewed tea drink.

[0020] When replacing the filter element and maintaining the equipment, unfasten the latch assembly, open the tank cover, and pull the vertical bar upward using the horizontal bar. Let the vertical bar slide upward in the groove to remove the two ring frames with the filter element installed from the filter tank as a whole. Then, reinstall another new whole filter frame into the tank. Alternatively, you can unscrew the bolt to remove the retaining ring from the ring frame and replace the first or second filter element separately.

[0021] This utility model has the following beneficial effects:

[0022] In this invention, the tea liquid is filtered three times in sequence through the first filter element, the second filter element, and the fine filter cloth, which can effectively remove impurities of different sizes and obtain a clear cold-brewed tea, ensuring the quality of the cold-brewed tea. In addition, the vibration motor drives the filter tank to vibrate, which allows the tea liquid to pass through the filter element better, improving the filtration efficiency and completing the filtration and clarification of cold-brewed tea in a shorter time.

[0023] This utility model allows for the replacement of the entire ring frame containing the filter element, or the replacement of the first or second filter element individually. Users can choose the appropriate replacement method according to their actual situation. The operation is convenient and quick, solving the problem of cumbersome filter element replacement in existing filtration and clarification equipment. The fine filter cloth is filled into the hollow cap and wrapped around the outlet of the discharge pipe. The hollow cap is then threaded to the bottom of the discharge pipe, ensuring a secure installation and facilitating the replacement of the fine filter cloth.

[0024] In this invention, the springs between the base and the hollow frame are arranged in a circular array, which can effectively reduce the transmission of vibration generated by the vibrating motor to the ground. Attached Figure Description
