Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation technology, and more specifically, to a water filtration device for tapioca pearls after cooking. Background Technology Currently, various industries require different filters to achieve solid-liquid separation in their production processes. A suitable filtration method can often make the solid-liquid separation more ideal. However, for some special products, such as tapioca pearls that do not need to be cooked, solid-liquid separation is required after cooking due to the requirements of the processing technology.

[0002] The inventors discovered in their research that existing devices for filtering water after cooking tapioca pearls have at least the following drawbacks: Due to the tendency of tapioca pearls to deform after cooking, existing extrusion filtration methods are unsuitable as they can easily lead to deformation. On the other hand, existing static filtration methods are prone to clogging the filter holes with tapioca pearls, resulting in unsatisfactory filtration effects, which can affect production time, reduce processing efficiency, and increase processing costs. Utility Model Content

[0003] The purpose of this invention includes, for example, providing a device for filtering water after cooking tapioca pearls, which can improve the solid-liquid separation effect and efficiency, reduce damage to tapioca pearls, and reduce the processing cost of tapioca pearls.

[0004] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides a water filtration device for tapioca pearls after cooking, comprising: The system includes a drive mechanism, an inner filter cage, and an outer filter cage. The outer filter cage is fitted over the inner filter cage, and the two work together to define an annular space for containing materials. The drive mechanism is simultaneously connected to both the inner and outer filter cages for driving them to rotate in opposite directions.

[0005] In an optional embodiment, the outer filter cage includes a hollow cylinder and a supporting bottom shell. The hollow cylinder is connected to the supporting bottom shell, and the inner filter cage passes through the hollow cylinder. The inner filter cage is rotatably connected to the supporting bottom shell. The inner filter cage, the hollow cylinder, and the supporting bottom shell cooperate to limit the annular space.

[0006] In an optional embodiment, the supporting bottom shell is configured as a conical shell, and the supporting bottom shell is provided with an inward conical surface for supporting materials.

[0007] In an optional embodiment, the inner filter cage is detachably connected to the supporting bottom shell.

[0008] In an optional embodiment, the external filter cage further includes a connector, which is connected to the side of the hollow cylinder away from the supporting bottom shell. The drive mechanism is connected to the connector and is used to drive the hollow cylinder and the supporting bottom shell to rotate through the connector.

[0009] In an optional embodiment, the device for filtering water after cooking tapioca balls further includes a housing with a discharge hole; the housing is sleeved on the outer filter cage, and the housing and the outer filter cage cooperate to define a drainage cavity communicating with the discharge hole; the drive mechanism is fixed on the housing.

[0010] In an optional embodiment, the bottom of the outer casing is spaced from the bottom of the outer filter cage, and the discharge hole is located at the bottom of the outer casing.

[0011] In an optional embodiment, the device for filtering water after cooking tapioca balls further includes a control valve mounted on the housing, the control valve being used to adjust the working state of the discharge port.

[0012] In an optional embodiment, the water filtration device for cooking tapioca pearls further includes a level gauge, which is installed on the outer or inner water filtration cage and is used to obtain the water level height in the annular space.

[0013] In an optional embodiment, the drive mechanism includes a dual-axis motor, which has a coaxial inner shaft and an outer shaft. The outer shaft is sleeved outside the inner shaft, and the inner shaft is drivenly connected to the inner filter cage, while the outer shaft is drivenly connected to the outer filter cage.

[0014] The beneficial effects of this utility model embodiment include, for example: In summary, the filtration device for cooked tapioca pearls provided in this embodiment places a mixture of tapioca pearls and liquid into an annular space. Since the density of the tapioca pearls is greater than that of the liquid, they tend to sink. The drive mechanism is activated, causing the inner and outer filter cages to rotate in opposite directions. The outer filter cage rotates at a higher speed than the inner filter cage, allowing the liquid to move outwards under the centrifugal force generated by the rotation of the outer filter cage. This liquid movement carries the tapioca pearls outwards, positioning them in the middle of the outer and inner filter cages. The distance between the tapioca pearls and both cages prevents clogging of the filter holes, allowing the liquid to drain effectively and resulting in high solid-liquid separation efficiency. Furthermore, because the inner and outer filter cages rotate in opposite directions, the liquid flow around the outer periphery of the inner filter cage is effectively disrupted, creating a turbulent flow that moves the tapioca pearls. This prevents multiple pearls from being squeezed together, forming a closed space where liquid cannot drain easily. Simultaneously, the centripetal force disrupts the flow of liquid from the surrounding area, resulting in smoother drainage and achieving rapid solid-liquid separation. Attached Figure Description

[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0024] Please refer to Figures 1-3 This embodiment provides a device for filtering water after cooking tapioca balls, which includes a drive mechanism 100, an inner filter cage 200 and an outer filter cage 300; the outer filter cage 300 is sleeved on the outside of the inner filter cage 200, and the two cooperate to define an annular space 001 for containing materials; the drive mechanism 100 is simultaneously connected to the inner filter cage 200 and the outer filter cage 300 for driving the inner filter cage 200 and the outer filter cage 300 to rotate in opposite directions.

[0025] As described above, the working principle of the water filtration device for cooked tapioca balls provided in this embodiment is as follows: A mixture of tapioca pearls and liquid is placed in an annular space 001. Since the density of the tapioca pearls is greater than that of the liquid, they tend to sink. The drive mechanism 100 is activated, causing the inner filter cage 200 and the outer filter cage 300 to rotate in opposite directions. The outer filter cage 300 rotates at a higher speed than the inner filter cage 200. The liquid moves outward under the centrifugal force generated by the rotation of the outer filter cage 300, carrying the tapioca pearls with it. This positions the tapioca pearls in the middle of the outer and inner filter cages 300, with sufficient space between them to prevent clogging of the filter holes. The liquid can then drain from these holes, resulting in good liquid drainage and high solid-liquid separation efficiency. Furthermore, because the inner filter cage 200 and the outer filter cage 300 rotate in opposite directions, the liquid flow around the outer periphery of the inner filter cage 200 is effectively disrupted, causing a turbulent flow around the inner filter cage 200. This facilitates the movement of the tapioca pearls, preventing multiple pearls from being squeezed together and forming a closed space, which would hinder the drainage of liquid within that space. Simultaneously, the disruption of centripetal force in the surrounding liquid flow results in smoother drainage, achieving rapid solid-liquid separation.

[0026] It should be understood that this water filtration device can be used not only for filtering tapioca pearls, but also for other materials that are not suitable for filtration by squeezing.

[0027] The following embodiments illustrate the details of the water filtration device for cooked tapioca balls of this application by way of example.

[0028] Please refer to Figures 1-8In this embodiment, optionally, the device for filtering water after cooking tapioca pearls includes a drive mechanism 100, an inner filter cage 200, an outer filter cage 300, a housing 400, a control valve 500, a level gauge 600, and a pull rod 700. The drive mechanism 100 is fixed to the housing 400. The housing 400, the outer filter cage 300, and the inner filter cage 200 are sequentially nested with a gap. The housing 400 and the outer filter cage 300 cooperate to define a drainage chamber 002, and the inner filter cage 200 and the outer filter cage 300 cooperate to define an annular space 001, into which the material formed by mixing tapioca pearls and liquid can enter. The control valve 500 is connected to the housing 400. The level gauge 600 can be connected to the inner filter cage 200, the outer filter cage 300, or the housing 400, and the level gauge 600 can obtain the liquid level height within the annular space 001. The pull rod 700 is connected to the inner filter cage 200 and can drive the inner filter cage 200 to rise and fall, thereby separating the inner filter cage 200 and the outer filter cage 300. The drive mechanism 100 is connected to both the inner filter cage 200 and the outer filter cage 300. The drive mechanism 100 can drive the inner filter cage 200 and the outer filter cage 300 to rotate synchronously in opposite directions, and can adjust the rotation speed of the inner filter cage 200 and the outer filter cage 300 as needed.

[0029] The mixture is placed in the annular space 001. The drive mechanism 100 drives the inner filter cage 200 and the outer filter cage 300 to rotate in opposite directions. Under the action of centrifugal force, the liquid can drive the tapioca pearls to move relative to the inner filter cage 200 and the outer filter cage 300. The tapioca pearls can be suspended in the middle of the inner filter cage 200 and the outer filter cage 300, and are not easy to come into contact with the inner filter cage 200 and the outer filter cage 300, and are not easy to clog the filter holes on the inner filter cage 200 and the outer filter cage 300, resulting in good solid-liquid separation effect.

[0030] In this embodiment, optionally, a feed hole 410 is provided at the top of the outer casing 400, which is used to add material into the annular space 001. A discharge hole 420 is provided at the bottom of the outer casing 400, which may be located at the center of the bottom of the outer casing 400. Furthermore, the inner surface of the bottom of the outer casing 400 may be a conical surface, with the discharge hole 420 located at the apex of the conical surface. The low position of the discharge hole 420 facilitates the discharge of liquid and separated tapioca pearls from the discharge hole 420.

[0031] Optionally, the level gauge 600 can be installed on top of the housing 400. With the housing 400 stationary and the level gauge 600 stationary, the level gauge 600 can easily obtain the liquid level height.

[0032] Optionally, the drive mechanism 100 may include a dual-axis motor, which has a coaxial inner shaft 110 and an outer shaft 120. The outer shaft 120 is sleeved on the outside of the inner shaft 110, and the bottom end of the inner shaft 110 extends out of the outer shaft 120, and the two are rotatably engaged. During assembly, the dual-axis motor is fixed to the bottom of the housing 400, and the two can be fixed with bolts, which facilitates disassembly and assembly. After installation, both the inner shaft 110 and the outer shaft 120 of the dual-axis motor are coaxially arranged with the housing 400. When the dual-axis motor is in operation, the rotation direction and speed of the outer shaft 120 and the inner shaft 110 can be adjusted as needed, allowing for flexible adjustment.

[0033] It should be understood that the dual-axis motor is a known existing structure, and its structure and working principle have not been improved in this embodiment. In order to avoid repetition and redundancy, its structure and working principle will not be described in detail in this embodiment.

[0034] In this embodiment, optionally, the inner filter cage 200 is provided with a plurality of first filter holes 210, which can be circular holes or strip-shaped holes, etc. The plurality of first filter holes 210 are arranged at intervals, and the number, shape, and size of the first filter holes 210 can be designed as needed. The inner filter cage 200 is mounted on the inner shaft 110, and the inner filter cage 200 and the inner shaft 110 can be connected by a key structure. The top of the inner filter cage 200 is sleeved on the outside of the inner shaft 110. The inner filter cage 200 and the inner shaft 110 are relatively fixed in the circumferential direction of the inner shaft 110, and the inner filter cage 200 and the inner shaft 110 are slidably connected in the axial direction of the inner shaft 110. Thus, the inner shaft 110 can drive the inner filter cage 200 to rotate together, and the inner filter cage 200 can rise and fall relative to the inner shaft 110.

[0035] Furthermore, an upper ring 220 is installed at the top of the inner filter cage 200, and a lower ring 230 is installed at the bottom. The lower ring 230 can be configured as a stepped structure. The upper ring 220 is sleeved on the outer shaft 110, and the lower ring 230 can be rotatably connected to the outer filter cage 300 or separated from it. Both the upper ring 220 and the lower ring 230 are annular structures, which are lightweight and low in cost. Moreover, after liquid enters the inner filter cage 200, it can be discharged from the lower ring 230. The pull rod 700 can be connected to both the upper ring 220 and the lower ring 230 simultaneously, which can improve the stability of the inner filter cage 200 structure.

[0036] In this embodiment, optionally, the external filter cage 300 includes a hollow cylindrical body 310, a supporting bottom shell 320, and a connector 330. The hollow cylindrical body 310 is provided with a plurality of second filter holes 311, the number, shape, and size of which can be designed as needed. The bottom of the hollow cylindrical body 310 is connected to the supporting bottom shell 320, and the two can be configured as an integral structure. The connector 330 is connected to the top of the hollow cylindrical body 310. The connector 330 can be a hollow component, which can provide a connection between the hollow cylindrical body 310 and the drive mechanism 100, and also reduce weight and material consumption.

[0037] Meanwhile, the supporting bottom shell 320 is designed as a conical shell with a concave conical surface 321 for carrying materials. This concave conical surface 321 design allows the tapioca pearls and liquid to concentrate on the outer circumference of the inner filter cage 200 during the final stage of solid-liquid separation, increasing the contact area and improving the agitation effect, thus enabling more thorough separation of the tapioca pearls from the liquid. Furthermore, the supporting bottom shell 320 is a closed structure, meaning it does not have filter holes. As a result, due to the weight of the tapioca pearls, they easily settle on the supporting bottom shell 320. If filter holes were added to the supporting bottom shell 320, the tapioca pearls would easily clog them, hindering drainage, restricting the movement of the tapioca pearls, reducing drainage efficiency, and making it difficult to clear the blockage and collect the tapioca pearls.

[0038] The assembly structure of the water filtration device provided in this embodiment is as follows: The inner filter cage 200 is inserted into the hollow cylinder 310. The lower ring 230 at the bottom of the inner filter cage 200 is inserted into the through hole 322 in the middle of the supporting base shell 320. Since the lower ring 230 has a stepped structure, it can limit the insertion depth. The inner filter cage 200 is rotatably connected to the supporting base shell 320, and the lower ring 230 can rise and fall relative to the supporting base shell 320. When the lower ring 230 rises, it can separate from the supporting base shell 320, exposing the through hole 322 in the middle of the supporting base shell 320, which facilitates the discharge of filtered tapioca pearls from the through hole 322. The inner filter cage 200, the hollow cylinder 310, and the supporting base shell 320 cooperate to limit the annular space 001, and the feed hole 410 connects to the annular space 001. The outer casing 400 covers the hollow cylindrical body 310, the supporting bottom shell 320, and the connecting piece 330. The outer casing 400 and the outer filter cage 300 cooperate to define a drainage chamber 002 that communicates with the discharge hole 420. Furthermore, there is a gap between the bottom of the outer casing 400 and the supporting bottom shell 320 of the outer filter cage 300, allowing the separated liquid to enter the drainage chamber 002 and then discharge from the discharge hole 420. A control valve 500 is installed at the bottom of the outer casing 400 and can control the opening or closing of the discharge hole 420. A dual-axis motor is fixed to the top of the outer casing 400. The inner shaft 110 of the dual-axis motor is drivenly connected to the upper ring 220 of the inner filter cage 200, and the outer shaft 120 of the dual-axis motor is drivenly connected to the outer filter cage 300.

[0039] Based on the above solutions, the working principle of the water filtration device for cooked tapioca balls in this embodiment is as follows: The mixture of tapioca pearls and liquid is fed into the annular space 001 through the feed port 410. The control valve 500 opens the discharge port 420, and the drive mechanism 100 is started. The drive mechanism 100 drives the inner filter cage 200 and the outer filter cage 300 to rotate in opposite directions. The entire separation process is roughly divided into two stages, as follows: In the initial stage, the water volume is large, the water level in the annular space 001 is high, and the tapioca pearls are basically submerged in the liquid. The buoyancy of the tapioca pearls is at its maximum, and the contact area between the liquid and the outer filter cage 300 is large. During this process, the rotation speed of the outer filter cage 300 is greater than that of the inner filter cage 200. The liquid can move outward under the action of the centrifugal force generated by the rotation of the outer filter cage 300. When the liquid moves, it can also carry the tapioca pearls outward. In this way, by reasonably adjusting the rotation speed, the tapioca pearls can be positioned in the middle of the outer filter cage 300 and the inner filter cage 200. There is a gap between the tapioca pearls and both the outer filter cage 300 and the inner filter cage 200, so the tapioca pearls are not likely to clog the filter holes on the outer filter cage 300 and the inner filter cage 200. The liquid can be discharged from the filter holes on the outer filter cage 300 and the inner filter cage 200, resulting in good liquid discharge and high solid-liquid separation efficiency. Furthermore, because the inner filter cage 200 and the outer filter cage 300 rotate in opposite directions, the liquid flow around the outer periphery of the inner filter cage 200 is effectively disrupted, causing a turbulent flow around the inner filter cage 200. This facilitates the movement of the tapioca pearls, preventing multiple pearls from being squeezed together and forming a closed space, which would hinder the drainage of liquid within that space. Simultaneously, the disruption of centripetal force in the surrounding liquid flow results in smoother drainage, achieving rapid solid-liquid separation.

[0040] As the water level drops, the separation process enters its final stage. During this stage, the water level gradually decreases, the water volume gradually diminishes, and the tapioca pearls are not submerged in the liquid, thus reducing the buoyancy of the pearls. The tapioca pearls and liquid are located on the concave conical surface 321 of the supporting base shell 320. Guided by the concave conical surface 321, the tapioca pearls and liquid gradually approach the outer circumference of the inner filter cage 200, concentrating the liquid and increasing the contact area between the liquid and the inner filter cage 200. At this point, increasing the rotation speed of the inner filter cage 200 to exceed that of the outer filter cage 300 allows the liquid to continue to move the tapioca pearls away from the inner filter cage 200 under centrifugal force. This prevents the tapioca pearls from clogging the first filter hole 210 on the inner filter cage 200, enabling further solid-liquid separation and improving the separation effect.

[0041] During the solid-liquid separation process, the liquid can be discharged from the first filter hole 210 and the second filter hole 311, enter the drain chamber 002, and be discharged from the discharge port. After the solid-liquid separation is completed, the drive mechanism 100 is turned off. The pull rod 700 installed on the inner filter cage 200 can be lifted off the supporting bottom shell 320 by using tools such as pliers or hooks. The through hole 322 in the middle of the supporting bottom shell 320 is exposed, and the tapioca pearls can be discharged from the discharge hole 420 under the action of weight. The tapioca pearls can be collected at the discharge hole 420.

[0042] It should be understood that in some embodiments, in order to achieve automatic lifting of the inner filter cage 200, a telescopic device can be provided on the inner shaft 110. The telescopic device, the inner shaft 110, and the inner filter cage 200 rotate together, and the telescopic device can drive the inner filter cage 200 to rise and fall relative to the inner shaft 110. The telescopic device can be controlled by a button or a remote control. For example, the telescopic device can be a stepper motor, an electric push rod, etc.

[0043] The device for filtering water after cooking tapioca balls provided in this embodiment can improve the separation effect between tapioca balls and liquid by reasonably controlling the solid-liquid separation process, and it causes little damage to the tapioca balls, which is beneficial to the processing of tapioca balls.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
