Description

Technical Field

[0001] This utility model relates to the field of processing technology of traditional Chinese medicine plant beverages, and in particular to a filtration device for traditional Chinese medicine plant beverages. Background Technology

[0002] Traditional Chinese medicine (TCM) herbal beverages are drinks with specific health benefits, made from Chinese medicinal herbs or plants that are both food and medicine, through extraction and blending. Filtration is a crucial step in the production process to ensure the clarity, stability, and sensory quality of the product. It primarily removes insoluble impurities such as plant fibers, colloids, and starch from the extract, preventing sedimentation or turbidity. Commonly used filtration devices include plate and frame filters and membrane separation equipment. Depending on the production scale and precision requirements, filter screens or media with different pore sizes can be selected for multi-stage filtration to achieve the desired clarification effect. These traditional filtration technologies achieve solid-liquid separation through physical retention, providing a fundamental guarantee for the industrial production of TCM herbal beverages.

[0003] However, the aforementioned devices have the following drawbacks: Both plate and frame filters and membrane separation equipment rely on filter cloth to physically remove tiny particulate impurities from beverages. As filtration progresses, the pores of the filter cloth become clogged with impurities, leading to increasingly slower filtration speeds and impacting overall filtration efficiency. Secondly, the filter components are typically fixed inside the device, making cleaning the surface of the filter components after each filtration cycle quite cumbersome. Therefore, further improvements are needed. To address this, we propose a filtration device for herbal beverages. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a filtration device for herbal plant beverages, comprising a base plate, a bottom cylinder fixed to the upper surface of the base plate, and two second electric telescopic rods fixed to the upper surface of the base plate and on both sides of the bottom cylinder. The telescopic ends of the two second electric telescopic rods are jointly and fixedly connected to a top cylinder. The top cylinder has the same diameter as the bottom cylinder and is open at both ends. A filtration assembly is held between the top cylinder and the bottom cylinder. A liquid injection pipe is fixed to the top of the side wall of the top cylinder, and a liquid drain pipe is fixed to the bottom of the side wall of the bottom cylinder. An L-shaped support plate is fixed to the side of the upper surface of the base plate, and a first electric telescopic rod is fixed to the top of the L-shaped support plate. A detachable pressure plate is fixed to the bottom telescopic end of the first electric telescopic rod, and the pressure plate is slidably connected to the inner wall of the top cylinder. A control cabinet is installed on the upper surface of the base plate.

[0006] Furthermore, the filter assembly includes a filter plate located on the upper surface of the bottom cylinder, the upper surface of the filter plate having a groove, the inner diameter of the groove being the same as the inner diameter of the top cylinder, the bottom of the groove having several leakage holes, and a filter cloth fixed to the bottom wall of the groove.

[0007] Furthermore, annular sealing gaskets are fixed on both the upper and lower surfaces of the filter plate, and the two sealing gaskets are respectively attached to the bottom cylinder and the top cylinder.

[0008] Furthermore, two symmetrical protrusions are fixed to the top of the bottom cylinder sidewall, and a slot for engaging the protrusions is provided on the lower surface of the filter plate. A handle is fixed to the side of the filter plate.

[0022] like Figures 1-4 As shown, a filtration device for herbal plant beverages is disclosed, comprising a base plate 1, a bottom cylinder 2 fixed on the upper surface of the base plate 1, and two second electric telescopic rods 10 fixed on both sides of the bottom cylinder 2 on the upper surface of the base plate 1. The telescopic ends of the two second electric telescopic rods 10 are fixedly connected to a top cylinder 3. The top cylinder 3 has the same diameter as the bottom cylinder 2 and is open at both ends. A filter assembly 4 is sandwiched between the top cylinder 3 and the bottom cylinder 2. An injection pipe 5 is fixed to the top of the side wall of the top cylinder 3, and a drain pipe 6 is fixed to the bottom of the side wall of the bottom cylinder 2. An L-shaped support plate 7 is fixed to the side of the upper surface of the base plate 1. A first electric telescopic rod 8 is fixed to the top of the L-shaped support plate 7. A detachable pressure plate 9 is fixed to the bottom telescopic end of the first electric telescopic rod 8 and is slidably connected to the inner wall of the top cylinder 3. A control cabinet 11 is installed on the upper surface of the base plate 1.

[0023] In this embodiment, all parts that come into contact with the herbal beverage are made of food-grade stainless steel.

[0024] The filter assembly 4 includes a filter plate 41 located on the upper surface of the bottom cylinder 2. A groove 42 is provided on the upper surface of the filter plate 41. The inner diameter of the groove 42 is the same as the inner diameter of the top cylinder 3. Several leakage holes 43 are provided at the bottom of the groove 42, and a filter cloth 44 is fixed on the bottom wall of the groove 42.

[0025] When the top cylinder 3 and the bottom cylinder 2 clamp the filter assembly 4 in the middle, the beverage to be filtered is injected into the top cylinder 3 through the injection pipe 5, and the beverage is filtered through the filter cloth 44. The filtered beverage passes through the leakage hole 43 into the bottom cylinder 2 and is then discharged from the drain pipe 6. The filtered impurities remain on the surface of the filter cloth 44.

[0026] Annular sealing gaskets 45 are fixed on both the upper and lower surfaces of the filter plate 41, and the two sealing gaskets 45 are respectively attached to the bottom cylinder 2 and the top cylinder 3.

[0027] By setting a sealing gasket 45, the sealing between the filter plate 41 and the bottom cylinder 2 and the top cylinder 3 can be increased, preventing beverage leakage from the joints.

[0028] Two symmetrical protrusions 21 are fixed at the top of the side wall of the bottom cylinder 2. The lower surface of the filter plate 41 is provided with a slot 46 for engaging the protrusions 21. A handle is fixed on the side of the filter plate 41.

[0029] The protrusion 21 can be inserted into the slot 46 to facilitate accurate positioning when installing the filter plate 41, and the handle makes it easy to pick up the filter plate 41.

[0030] Both the first electric telescopic rod 8 and the second electric telescopic rod 10 are electrically connected to the control cabinet 11.

[0031] In this embodiment, the control cabinet 11 controls the extension and retraction of the first electric telescopic rod 8 and the second electric telescopic rod 10 using existing technology; the specific models of the first electric telescopic rod 8 and the second electric telescopic rod 10 are not limited. The control cabinet 11 has a built-in PLC controller, which can be an S7-1200 series (small and medium-sized automation) CPU 1214C (6ES7214-1BG40-0XB0). Its working principle is as follows: after the PLC receives the operation command, the motor drives the lead screw to realize the extension and retraction movement.

[0032] The upper surface of the pressure plate 9 is rotatably connected to the inner threaded sleeve 91 via a bearing. The bottom telescopic end of the first electric telescopic rod 8 is fixed with a screw 81, and the inner threaded sleeve 91 is rotatably connected to the surface of the screw 81 via a thread.

[0033] By screwing the internal threaded sleeve 91 onto the surface of the screw 81, the pressure plate 9 is fixedly connected to the telescopic end of the first electric telescopic rod 8. The first electric telescopic rod 8 can drive the pressure plate 9 to move inside the top cylinder 3.

[0034] A sealing ring is fixed to the outer wall of the pressure plate 9, and the sealing ring fits against the inner wall of the top cylinder 3. The sealing ring improves the sealing performance between the side of the pressure plate 9 and the inner wall of the top cylinder 3.

[0035] Working principle: First, the beverage to be filtered is injected into the top cylinder 3 through the injection pipe 5. The beverage is filtered through the filter cloth 44. The filtered beverage passes through the leakage hole 43 into the bottom cylinder 2 and is then discharged from the drain pipe 6. The filtered impurities remain on the surface of the filter cloth 44. As the beverage is injected, when the filtration speed slows down significantly, the injection is stopped. Then, the first electric telescopic rod 8 is activated to extend and lower the pressure plate 9, using the pressure plate 9 to filter the beverage in the top cylinder 3. After filtration is completed, the first electric telescopic rod 8 is controlled to shorten and reset the pressure plate 9. Then, the second electric telescopic rod 10 is activated to extend and move the top cylinder 3 upward. At this time, the filter assembly 4 can be directly removed from the top of the bottom cylinder 2, and another filter assembly 4 can be installed on the top of the bottom cylinder 2 to continue filtering the herbal beverage. The removed filter assembly 4 can be cleaned for future use.
