Description

Technical Field

[0001] This utility model relates to the field of plum filtration, and in particular to a multi-stage linkage plum filtration device. Background Technology

[0002] As a popular health drink, the taste, clarity, and stability of plum juice are key indicators of its quality. These indicators largely depend on the filtration process during production. Plum juice contains complex components such as pulp, pectin, fiber, protein, and suspended particles, which need to be effectively separated through multi-stage filtration to obtain a crystal clear and flavorful final product.

[0003] Currently, most filtration devices for green plums on the market adopt a split, multi-unit independently driven design, which connects different filtration units such as coarse filtration, fine filtration, and ultrafiltration as independent devices. However, because each unit is physically isolated, the material is prone to secondary pollution or oxidation during the transfer from one stage to the next due to excessive residence time or exposure to air. Furthermore, due to the lack of rigid linkage, the operation of each unit cannot form an organic whole, making it difficult to coordinate and optimize for the characteristics of green plums, thus affecting the final filtration effect and product quality stability.

[0004] Therefore, in view of the problems that existing Qingmeishuang filtration devices cannot or are difficult to perform multi-stage linkage and that the filter screen in the device is inconvenient to remove, a Qingmeishuang filtration device that solves the above problems is needed.

[0030] Example 1: As Figure 1 - Figure 4As shown, a multi-stage linkage plum-based filtration device includes a housing 1. A motor 7 is fixedly connected to the right end of the outer wall of the housing 1. The drive end of the motor 7 passes through the inner wall of the housing 1 and is fixedly connected to a rotating column 12. A bracket 11 is rotatably connected to the right end of the outer wall of the rotating column 12. A top plate 6 is fixedly connected to the bottom end of the bracket 11. A transmission assembly is provided on the inner wall of the top plate 6. The top plate 6 is connected to a stirring roller 21 through the transmission assembly. The transmission assembly includes a connecting column 26 rotatably connected to the top end of the inner wall of the top plate 6. A second bevel gear 25 is fixedly connected to the top end of the connecting column 26. A first bevel gear 24 is meshed with the outer wall of the second bevel gear 25. The inner wall of the first bevel gear 24 is fixedly connected to the outer wall of the rotating column 12. The left end of the outer wall of the rotating column 12 is fixedly connected to... There is an impact column 13, the outer wall of which rotates inside the housing 1. Fixed columns 15 are fixedly connected to the four corners of the top of the top plate 6. Impact plates 14 are slidably connected to the outer walls of the fixed columns 15. The top of the impact plates 14 collides with the first filter box 2. A bottom block 19 is fixedly connected to the bottom of the impact plates 14. A rotating wheel 20 is rotatably connected to the bottom of the inner wall of the bottom block 19. The bottom of the rotating wheel 20 collides with the impact column 13. A blocking block 31 is fixedly connected to the outer wall of the fixed columns 15. The top of the blocking block 31 is used to support the impact plates 14. A third bevel gear 27 is fixedly connected to the bottom of the connecting column 26. A fourth bevel gear 28 is meshed with the outer wall of the third bevel gear 27. A rotating column 23 is fixedly connected to the outer wall of the fourth bevel gear 28. The outer wall of the rotating column 23 is rotatably connected to the inner wall of the top plate 6. The outer wall of the top plate 6 is fixedly connected to the right end of the inner wall of the box 1. The outer wall of the rotating column 23 is rotatably connected to the mixing tank 18. The right end of the mixing tank 18 is fixedly connected to the left end of the outer wall of the top plate 6. The left end of the rotating column 23 is fixedly connected to the stirring roller 21, which is used to stir the pre-filtered plum juice. The left end of the mixing tank 18 is fixedly connected to the bottom pipe 22, the bottom end of which is aligned with the top end of the second filter box 3. The top end of the mixing tank 18 is fixedly connected to the guide pipe 17, and the top end of the guide pipe 17 is fixedly connected to the connecting box. The top end of the connecting box is provided with the discharge port 16, and the outer wall of the discharge port 16 is fixedly connected to the inside of the box 1. The first filter box 2, the second filter box 3, and the third filter box are connected together. Each of the boxes 4 has a discharge port 16 at its bottom. When the first filter box 2, the second filter box 3, and the third filter box 4 are all fully inserted into the box body 1, the bottoms of the first filter box 2, the second filter box 3, and the third filter box 4 are completely closed with the corresponding discharge ports 16. The first filter box 2, the second filter box 3, and the third filter box 4 are located on the right side of the inner wall of the box body 1. The first filter box 2, the second filter box 3, and the third filter box 4 are equipped with a coarse filter, a fine filter, and an ultrafiltration membrane. The coarse filter is used to block fruit pit fragments, larger fruit peels, fruit stems, and coarse plant fibers in the plum juice. The fine filter is used to block small fruit pulp particles, finer fiber bundles, and some colloidal clumps in the plum juice.The ultrafiltration membrane is used to block pectin, protein, and most microorganisms in the plum juice. A coarse filter, a fine filter, and the ultrafiltration membrane are used for layer-by-layer filtration of the plum juice. A storage tank is located at the bottom of the inner wall of the housing 1 to store the filtered plum juice. A valve 9 is fixedly connected to the bottom right side of the housing 1 to discharge the plum juice from the storage tank. An inlet 5 is fixedly connected to the top of the housing 1 to allow the plum juice raw material to fall into the housing 1 onto the coarse filter on the first filter box 2. A discharge port 10 is fixedly connected to the left end of the housing 1 to discharge any remaining pulp, pit fragments, larger peels, stems, and coarse plant fibers from the plum juice raw material filtered through the coarse filter.

[0031] Specifically, by starting motor 7, its output shaft drives rotating column 12 to rotate at high speed under the support of bracket 11. Then, the rotation of rotating column 12 drives the first bevel gear 24 fixed on it to rotate synchronously. Since the first bevel gear 24 meshes with the second bevel gear 25, the horizontal rotational power is converted into vertical rotational power. The second bevel gear 25 drives connecting column 26 to rotate in the bearing of top plate 6. Then, since the lower end of connecting column 26 is connected to third bevel gear 27, and the outer wall of third bevel gear 27 meshes with the horizontally installed fourth bevel gear 28, the vertical rotational power is converted into horizontal rotational power again. Finally, fourth bevel gear 28 drives rotating column 23 to rotate, thereby driving the rotating column 23 to rotate. The stirring roller 21 begins to rotate efficiently inside the mixing tank 18, preparing for subsequent material shearing. Simultaneously, the impact column 13, fixed to the rotating column 12, undergoes circular motion. Along its rotation path, the impact column 13 collides with the rotating wheel 20. This collision force is transmitted through the rotating wheel 20 to the rigidly connected bottom block 19, and then from the bottom block 19 to the fixed impact plate 14. Guided by the fixed column 15, the impact plate 14 converts the instantaneous impact force into upward linear motion, violently impacting the bottom of the first filter box 2. With the continuous rotation of the motor 7, the impact column 13 periodically collides with the rotating wheel 20. Then, as the impact column 13 slides down, it causes the impact plate 14 to slide downwards on the fixed column 15, eventually stopping on the blocking block 31. To prevent the rotating wheel 20 from sliding down and impacting the impact column 13, thus affecting the rotating column 12, the first filter box 2 generates continuous and stable high-frequency micro-vibration. After multi-stage linkage and stable operation, the filtration operation can begin. The raw material of the plum juice is then poured into the box 1 through the feed port 5. The raw material first falls on the coarse filter screen of the first filter box 2, which is vibrating at high frequency. Under the dual action of vibration and gravity, the raw material is quickly spread out and shaken. Large impurities such as fruit pit fragments, larger fruit peels, and fruit stems are effectively intercepted and move to the edge with the vibration. Finally, they are automatically discharged from the device through the discharge port 10 on the side wall of the box 1. The preliminary filtrate that has passed through the coarse filter screen flows out from the discharge port 16 at the bottom of the first filter box 2 and passes through the connecting box and guide pipe 1. 7. The liquid is precisely introduced into the mixing tank 18 below. Inside the mixing tank 18, the liquid is intensely stirred and sheared by the high-speed rotating stirring roller 21, further breaking down and refining any clumps of fruit pulp and colloidal clumps. The material, after being stirred and sheared, drips through the bottom pipe 22 at the bottom of the mixing tank 18 onto the fine filter screen of the second filter box 3. The fine filter screen blocks and intercepts small fruit pulp particles, fine fiber bundles, and some colloidal clumps from the plum juice. Finally, the clarified liquid after secondary filtration drips from the outlet 16 at the bottom of the second filter box 3 onto the ultrafiltration membrane of the third filter box 4 at the bottom. Here, the ultrafiltration membrane thoroughly removes residual pectin, protein, microorganisms, and other nanoscale impurities from the liquid.A clear and stable finished product is obtained. The product ultimately passes through the ultrafiltration membrane and collects from the outlet 16 at the bottom of the third filter box 4 into the storage tank at the bottom of the housing 1. When it is necessary to collect the finished product, simply open the valve 9 installed at the bottom of the collection chamber to smoothly discharge the filtered plum juice.

[0032] Example 2: As Figure 1 and Figure 5 As shown, a handle 8 is slidably connected to the rear end of the inner wall of the box 1, a card plate is fixedly connected to the front end of the handle 8, and several card posts are fixedly connected to the front end of the card plate. The rear end of the outer wall of the first filter box 2, the second filter box 3 and the third filter box 4 are all provided with card slots 29. The size of the card slots 29 is adapted to the card posts. Compression springs 30 are fixedly connected to the upper and lower sides of the rear end of the card plate. The rear end of the compression springs 30 is fixedly connected to the rear end of the inner wall of the box 1.

[0033] Specifically, the operator prepares the first filter box 2 (with a built-in coarse filter), the second filter box 3 (with a built-in fine filter), and the third filter box 4 (with a built-in ultrafiltration membrane). Then, holding the handle 8 at the front of the housing 1 with one hand, the operator applies a steady backward force. This force is transmitted through the handle 8 to the connected locking plate, driving the locking plate and its locking pins to retract synchronously towards the rear end of the inner wall of the housing 1. During this process, the locking plate compresses the compression spring 30 installed on the inner wall of the housing 1, storing potential energy for the subsequent locking action. Then, when the locking pins have completely retracted into the internal space of the housing 1, creating sufficient installation clearance, the operator inserts the three filter boxes into the housing from top to bottom. In step 1, the filter box is pushed to the end of its stroke. When the filter box is pushed to the bottom, the pre-set slots 29 on the side wall of each filter box will be precisely aligned with the initial position of the locking post. At this time, the pull handle 8 is released, and the compressed spring 30 instantly releases the stored elastic potential energy, generating a strong rebound force. This force pushes the locking plate and locking post to quickly reset outward until the front end of the locking post is precisely and firmly locked into the slot 29 of the corresponding filter box, thereby completing the axial and radial limiting of all filter boxes. After the filter box is installed in place, because it is pushed to the bottom, the bottom of the filter box is tightly fitted with the top of the discharge port 16 of each level inside the box 1, ensuring that the material will not leak during the filtration process.

[0034] Working principle: First, remove the first filter box 2, the second filter box 3, and the third filter box 4. Then, by pulling the handle 8 backward, the handle 8 causes the locking plate and the locking pins on the locking plate to retract towards the inside of the housing 1. At the same time, the locking plate compresses the compression spring 30. After the locking pins retract into the housing 1, the first filter box 2, the second filter box 3, and the third filter box 4 can be inserted into the housing 1 and pushed all the way down until the locking slots 29 on all the filter boxes are engaged. Then, release the handle, and the compression spring 30 will rebound, locking the locking pins into the locking slots 29 on the first filter box 2, the second filter box 3, and the third filter box 4, thus limiting the filter boxes. Finally, by pushing all the filter boxes all the way down, the filter... The bottom of the box is completely closed to the top of the discharge port 16 in the housing 1. Then, by starting the motor 7, the motor 7 drives the rotating column 12 to rotate on the support 11. The rotation of the rotating column 12 then drives the first bevel gear 24 to rotate. The first bevel gear 24 then drives the meshing second bevel gear 25 to rotate. The second bevel gear 25 drives the connecting column 26 to rotate in the top plate 6. The connecting column 26 then drives the third bevel gear 27 to rotate. The third bevel gear 27 then drives the meshing fourth bevel gear 28 to rotate. The rotation of the fourth bevel gear 28 then drives the rotating column 23 to rotate. The rotating column 23 then drives the stirring roller 21 to rotate in the mixing tank 18. The rotating column 12 drives the impact column 13 to rotate, causing the impact column 13 to collide with the rotating wheel 20. The rotating wheel 20 transmits the impact force to the bottom block 19, which in turn transmits the force to the impact plate 14. The impact plate 14 slides upward on the fixed column 15 and collides with the bottom of the first filter box 2, causing the first filter box 2 to vibrate. Then, the raw material of the plum juice can be poured into the box 1 through the feed port 5, causing the raw material to fall onto the coarse filter screen of the first filter box 2. The vibration of the first filter box 2 blocks and filters out fruit pit fragments, larger fruit peels, fruit stems, etc., from the raw material and discharges it from the discharge port 10 on the box 1. After the first filtration, the plum juice is fed from the discharge port 16 at the bottom of the first filter box 2 into the guide pipe 17 through the connecting box, and then into the mixing tank 18. After being stirred and broken up by the stirring roller 21, it drips through the bottom pipe 22 onto the fine filter screen on the second filter box 3 for further filtration. This process blocks and intercepts small fruit pulp particles, fine fiber bundles, and some colloidal clumps in the plum juice. Then, it drips through the corresponding discharge port 16 at the bottom onto the ultrafiltration membrane on the third filter box 4 for final filtration. Finally, it enters the storage tank at the bottom of the box 1 through the corresponding discharge port 16 at the bottom of the third filter box 4. Then, opening the valve 9 allows the multi-filtered finished product to be discharged from the device.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
