Technical Field
[0001] This utility model relates to the field of dairy beverage processing technology, and in particular to a device for removing impurities from dairy beverages based on molecular membrane filtration. Background Technology
[0002] Milk beverage impurity removal typically refers to the removal of non-milk solids and contaminants introduced during preparation, processing, or storage. Milk beverages are drinks made from dairy products, mixed with other ingredients through a process of milk pulp or emulsion. Common examples include formula milk, lactic acid drinks, yogurt, and milk tea. They may be primarily made from fresh milk, whole milk, or skim milk, and may also contain added water, sugar, fruit juice, flavorings, stabilizers, and seasonings.
[0003] However, traditional dairy beverage impurity removal equipment typically uses a single filter screen and a membrane element as its core, making it difficult to accurately classify and intercept large, medium, and microparticles in the same process. This can easily lead to clogging at the front end, reduced throughput at the back end, and the accumulation of contaminants such as protein, fat, and adhesive particles in the beverage raw materials. This results in problems such as accelerated membrane fouling rate, increased cleaning intensity, and increased downtime.
[0004] Therefore, those skilled in the art have provided a device for removing impurities from milk beverages based on molecular membrane filtration to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a molecular membrane filtration-based impurity removal device for dairy beverages. This device is equipped with a filtration mechanism. Initial filtration of the incoming raw material is performed by a metal filter screen on a fixed frame, removing large particles to protect subsequent filter screens and membrane elements, reducing the risk of membrane fouling and clogging. A secondary, finer filtration is then performed by a fiber filter screen to intercept medium-sized particles, reducing the impact of larger particles (slightly smaller than the metal screen) on the membrane. Finally, a third filtration separation occurs through sedimentation and permeation of the filtration membrane, efficiently separating particulate matter and soluble impurities for a finer purification effect, thereby improving the filtration efficiency of the device.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A milk beverage impurity removal device based on molecular membrane filtration includes a filter tank. The filter tank has an internal filtration mechanism, which includes a drive base, a positioning slot, a sedimentation casing, a sealing transmission ring, and a feed pipe. A first servo motor is fixedly connected to the center of the lower surface of the drive base. A filter membrane is fixedly connected to the inner bottom surface of the sedimentation casing. An inner cylinder is rotatably connected to the upper surface of the drive base. Multiple filter grooves are formed on the outer wall of the inner cylinder. Multiple filter frames are fitted into the inner wall of the inner cylinder. Fiber filter screens are fixedly connected to the inner wall of each filter frame. A trapezoidal sealing groove is formed on the lower surface of the sealing transmission ring. A connector is fixedly connected to the center of the upper surface of the feed pipe. A fixing frame is threaded onto the lower end of the inner wall of the feed pipe. Multiple metal filter screens are fixedly connected to the inner wall of the fixing frame. A can lid is fixedly connected to the upper surface of the filter can, and a mixing mechanism is provided on the lower surface of the can lid. The mixing mechanism includes a second servo motor and a rotating shaft. A mixing frame is fixedly connected to the outer wall of the rotating shaft, and multiple silicone diagonal strips are fixedly connected to the outer wall of the mixing frame.
[0007] Through the above technical solution, the equipment is equipped with a dual mixing structure.

At the same time, under the drive of the second servo motor, the mixing frame with the silicone inclined strip is controlled to rotate in the opposite direction at a low speed. This improves the filtration effect of the equipment. Moreover, the silicone inclined strip can adhere to the inner cylinder to sweep the inner wall of the fiber filter, thereby reducing the accumulation of deposits and extending the service life of the equipment.
[0008] Furthermore, the drive base is fixedly connected to the lower end of the inner wall of the filter tank, and a trapezoidal groove is provided around the upper surface of the drive base. The output end of the first servo motor passes through the drive base and is fixedly connected to the inner cylinder. Through the above technical solution, the first servo motor can drive the inner cylinder, thereby enabling the inner cylinder to rotate at a low speed, so as to reduce the accumulation of impurities on the filter screen.
[0009] Furthermore, the positioning slots are respectively opened at the upper end of the inner wall of the filter tank, the sedimentation casing is snapped into the inner wall of the filter tank, and multiple positioning blocks are fixedly connected to the upper end of the outer wall of the sedimentation casing. The above technical solution enables the sedimentation cartridge to be installed tightly and securely inside the filter tank, thereby allowing the filtered raw materials to undergo sedimentation filtration.
[0010] Furthermore, a sealing slot is provided at the lower end of the inner wall of the filter tank, and an installation slot is provided at the upper end of the inner wall of the filter tank. A sealing block is fixedly connected to the lower end of the outer wall of the filter frame, and an installation block is fixedly connected to the upper surface of the filter frame. The above technical solution allows the filter frame to be securely fastened within the filter chamber, enabling users to quickly replace and clean the fiber filter screen through disassembly and replacement.
[0011] Furthermore, the sealing drive ring is rotatably connected to the lower surface of the can lid, the trapezoidal sealing groove is engaged with the inner cylinder, and the feed pipe is fixedly connected to one side of the upper surface of the can lid; The above technical solution enables the inner cylinder to be engaged and fitted with the sealing drive ring, thereby forming a sealed space.
[0012] Furthermore, the second servo motor is fixedly connected to the center of the upper surface of the can lid, the rotating shaft is rotatably connected to the center of the lower surface of the can lid, and the output end of the second servo motor passes through the can lid and is fixedly connected to the rotating shaft; The above technical solution enables the second servo motor to drive the rotating shaft, thereby controlling the mixing frame to rotate at a low speed.
[0013] Furthermore, a support frame is fixedly connected to the lower surface of the filter tank, and handles are fixedly connected to both the front and rear ends of the upper surface of the tank cover; The above technical solution enables users to open and disassemble the can lid using the handle.
[0014] Furthermore, a discharge pipe is fixedly connected to one side of the lower end of the outer wall of the filter tank, a manual valve is fixedly connected to the middle of the outer wall of the discharge pipe, and a flange is fixedly connected to the outer wall of one side of the discharge pipe. The above technical solution enables the collected and filtered container to be fixed to the discharge pipe by a flange bolt, and the discharge pipe can be opened or closed by a manual valve.

[0025] Working principle: First, the servo motors (first servo motor 202 and second servo motor 401) are powered on. The liquid raw material injection pipe is connected to the connector 2019, and the collection pipe after the liquid raw material is filtered is connected to the discharge pipe 7. As the power is turned on, the servo motors start, controlling the inner cylinder 208 and the rotating shaft 402 to rotate at low speeds in different directions. This allows the mixing frame 403 to control the silicone inclined strip 404 to adhere to and sweep against the fiber filter screen 2013 (polypropylene material) on the inner cylinder 208. When the raw material is injected into the equipment, it is first filtered by the metal filter screen 2021 (stainless steel) on the fixed frame 2020. The steel filter initially intercepts a small number of larger particles that are not properly filtered. The particles then enter the sealed cavity formed by the inner cylinder 208 and the sealing drive ring 2016. As the inner cylinder 208 rotates at a low speed, the raw material continuously permeates and is filtered through the fiber filter screen 2013 and collected in the sedimentation cassette 205. A large number of medium-sized particles are intercepted in the inner cylinder 208. The permeated raw material undergoes three permeation filtrations through the filter membrane 207 and is guided by the trapezoidal groove 203 to the discharge pipe 7. Finally, it is collected and discharged into the container. After use, the various filter components can be disassembled for cleaning, maintenance, or replacement.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
