Description

Technical Field

[0001] This invention relates to the technical field of storage tanks, and more particularly to a sealed storage device for anti-caking vegetable oil powder. Background Technology

[0002] Non-dairy creamer storage tanks are specially designed airtight storage containers for storing non-dairy creamer. They are mostly made of food-grade stainless steel and have excellent sealing and hygiene properties. The tanks are often equipped with stirring, temperature control, moisture-proof, and discharge devices to prevent the non-dairy creamer from becoming damp, clumping, oxidizing, and deteriorating. They are widely used for large-scale storage of raw materials in industries such as milk tea, baking, and food processing.

[0003] Patent CN107867505A discloses a material storage tank based on a vibration device, including a storage tank body 1. A partition 4 is inclinedly arranged inside the storage tank body 1. The storage tank body 1 is provided with a discharge port 5, a feed port 3, and a sealing device for sealing the discharge port 5 located on the outside of the storage tank body 1. A storage cavity 10 is formed between the partition 4 and the top of the storage tank body 1, and an installation cavity 16 is formed between the partition 4 and the bottom of the storage tank body 1. A vibration device for vibrating the partition 4 is provided inside the installation cavity 16.

[0004] The existing technology has the following drawbacks: Existing technologies related to the storage of non-dairy creamer have several issues that require optimization in practical applications: most technologies focus on a single storage function, and the anti-caking function is not effectively integrated with the storage structure, requiring additional decoction equipment, resulting in a relatively cumbersome overall process and increased space occupation and equipment investment costs; some anti-caking solutions rely on external power, which limits the application scenarios and increases energy consumption and maintenance costs; anti-caking treatment often adopts a single action mode, making it difficult to achieve a layered and progressive fine effect, and the dispersion of agglomerated powder is insufficient; there is a lack of precise control mechanisms for the operation sequence of the sieving components, which may lead to incomplete sieving; some structural designs have limited adaptability, making it difficult to meet the needs of repeated anti-caking operations and unable to maintain the loose state of the powder stably for a long time; the guiding and coordination design of internal moving parts needs improvement, as they are prone to misalignment or jamming, affecting operational stability and shortening the service life of components; a few equipment have relatively complex operation procedures, requiring high operator skills, which reduces efficiency to some extent. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, a sealed storage device for anti-caking vegetable oil powder is proposed.

[0006] This application provides a sealed storage device for non-caking non-dairy creamer, the purpose of which is to provide a non-dairy creamer storage tank with good anti-caking effect.

[0007] The technical solution of the present invention is: a sealed storage device for anti-caking vegetable oil powder, comprising a bracket, a pair of support shafts disposed on the bracket, an outer tank disposed between the pair of support shafts, and an inner tank slidably disposed within the outer tank; The inner tank is slidably equipped with a powder screening unit. The powder screening unit includes a support ring that fits against the inner wall of the inner tank and a horizontal plate set in the middle of the support ring. Multiple arc-shaped powder screening holes are set at the junction of the support ring and the horizontal plate. A rotating platform is rotatably set at the center of the horizontal plate. A pair of rotating shafts are symmetrically arranged in the horizontal direction at the eccentric part of the rotating platform. Each rotating shaft is connected to a conical cap. The pair of conical caps are symmetrically arranged along the horizontal plate and the apexes are far apart from each other. Powder screening blades are evenly spaced on the edge of the conical caps. The powder screening blades are inclined and extend above the powder screening holes. Under normal conditions, the sieving unit is located above the powder. After rotating the outer tank 180°, the powder falls through the sieving holes and drives the sieving blades to rotate, thus refining the powder.

[0008] Furthermore, a rotating rod is provided on one of the support shafts.

[0009] Furthermore, the inner tank is provided with a lid at the top and a discharge pipe at the bottom. The outer tank is provided with a through hole at the corresponding position of the discharge pipe. When the inner tank slides vertically, the through hole and the discharge pipe do not interfere with each other.

[0010] Furthermore, the inner wall of the outer tank is vertically provided with multiple limiting ribs, and the outer wall of the inner tank is provided with multiple sets of sliding plates that match the limiting ribs.

[0011] Furthermore, a pair of limiting rings are provided on the inner wall of the outer tank to limit the sliding stroke of the sliding plate.

[0012] Furthermore, a thrust bearing is provided at the center of the horizontal plate, and retaining rings are provided on both the upper and lower end faces of the thrust bearing. The end face of the thrust bearing and the retaining rings are fitted with a clearance fit. The rotary table is snapped into the thrust bearing, and the rotary table and the end face of the thrust bearing are fitted with a clearance fit.

[0013] Furthermore, the powder screening unit also includes a falling reset assembly. At least two sets of falling reset assemblies are provided. Each set of falling reset assemblies includes a locking block rotatably disposed on the outer wall of the support ring and a pair of pressure blocks symmetrically disposed on the horizontal plate. Each pressure block is provided with a pressure rod extending in the direction of the horizontal plate. Each pressure rod end abuts against a swing rod. One end of the swing rod is hinged to the horizontal plate, and the other end abuts against the locking block.

[0014] Furthermore, the bottom of the pressure-bearing block is provided with multiple guide posts, and a guide ring matching the guide posts is provided inside the horizontal plate.

[0015] Furthermore, multiple weak springs abut against the horizontal plate and the pressure block.

[0016] Furthermore, the locking block is provided with symmetrical oblique sliding grooves, and the end of the swing rod abuts in the oblique sliding groove.

[0017] The beneficial effects of this invention are: The equipment adopts a double-layer tank structure with an outer tank and an inner tank. The inner tank, together with the tank cover, forms an independent sealed space, which can effectively isolate external moisture, dust and impurities, ensuring the quality of the non-dairy creamer during storage. At the same time, it integrates a dedicated anti-caking treatment structure, eliminating the need for additional independent decoction equipment, simplifying the storage and processing process, and saving equipment space and operating costs. The entire system relies on gravity, mechanical impact and mechanical transmission to achieve anti-caking operation, without relying on electricity or other external drive sources. The operation process has low energy consumption and high safety, making it suitable for various production and warehousing scenarios and reducing the difficulty of equipment use and maintenance.

[0018] The powder is fully refined and dispersed through a dual action. On the one hand, the vibration generated by the inner tank sliding down and hitting the limiting ring after the inner tank is overturned can initially disperse the agglomerated powder. On the other hand, the powder screening unit drives the powder screening blades to rotate, which shears and refines the powder. Combined with the additional vibration generated by the rotation of the eccentrically set conical cap, the powder is further crushed, which greatly improves the effect of preventing agglomeration and refining the powder.

[0019] The matching falling reset component can automatically adjust the falling timing of the sieving unit according to the pressure change of the powder. When the powder has not finished sieving and falling, the locking block increases the friction between the support ring and the inner tank, preventing the sieving unit from falling prematurely, ensuring that the powder is fully refined through the sieving structure. After most of the powder has fallen, the obstruction is automatically released, ensuring the sieving process is complete and orderly and improving the stability of operation.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example, refer to Figures 1-5 In this embodiment of the invention, an anti-caking resin powder sealing storage device is provided. The bracket 1 is the basic load-bearing component of the device. A pair of support shafts 2 are horizontally installed on the bracket 1. The outer tank 3 is set between the two support shafts 2 and is provided with rotational support by the support shafts 2. A rotating rod 13 is fixedly installed on one of the support shafts 2. The rotating rod 13 serves as an operating component and can be held by the operator to apply force and drive the outer tank 3 to rotate around the support shaft 2.

[0024] The inner tank 4 is slidably disposed inside the outer tank 3, forming a double-layer tank structure. The top of the inner tank 4 is provided with a lid 14, which cooperates with the inner tank 4 to form a sealed space for directly storing the vegetable oil powder, preventing moisture and impurities from the external environment from contacting the material. A discharge pipe 15 is provided at the bottom of the inner tank 4 for discharging the material. A through hole 16 is provided on the outer tank 3 at the position corresponding to the discharge pipe 15. The size and position of the through hole 16 ensure that when the inner tank 4 slides vertically inside the outer tank 3, there will be no interference between the discharge pipe 15 and the through hole 16 of the outer tank 3, thus not affecting the normal sliding of the inner tank 4 and subsequent material discharge operations.

[0025] The inner wall of the outer tank 3 is provided with multiple limiting ribs 17 along the vertical direction, and the outer wall of the inner tank 4 is provided with multiple sets of sliding plates 18. The shape and position of the sliding plates 18 and the limiting ribs 17 are matched. The sliding plates 18 can move up and down by conforming to the limiting ribs 17. The limiting ribs 17 provide vertical guidance for the sliding plates 18 and the inner tank 4, constraining the inner tank 4 to slide only in the vertical direction, avoiding circumferential rotation or horizontal displacement of the inner tank 4 during sliding, and reducing direct friction between the inner tank 4 and the inner wall of the outer tank 3. The inner wall of the outer tank 3 is also provided with a pair of limiting rings 19. The two limiting rings 19 are distributed at intervals along the vertical direction. The distance between the two is greater than the distance between the uppermost sliding plate 18 and the lowermost sliding plate 18 on the outer wall of the inner tank 4, thereby limiting the sliding stroke of the sliding plates 18, preventing the inner tank 4 from sliding excessively, and providing impact limit for the sliding plates 18.

[0026] In use, the operator holds the rotating rod 13 and rotates the outer can 3 180 degrees around the support shaft 2. After the outer can 3 flips over, the inner can 4 slides vertically down inside the outer can 3 under its own weight, guided by the limiting rib 17, until the sliding plate 18 collides with the limiting ring 19 below. The vibration generated by the collision is transmitted to the inside of the inner can 4 and acts on the clumps of vegetable oil powder inside the can, causing the clumps of powder to loosen under the vibration and impact, making it easier to discharge and use later.

[0027] Reference Figures 6-8 The inner tank 4 has a sliding sieving unit 5. This unit serves as the actuator for refining powder and preventing agglomeration. It is adapted to the sliding structure of the inner tank 4 to jointly complete the dispersion of the vegetable oil powder. The sieving unit 5 mainly consists of a support ring 6, a horizontal plate 7, a rotary table 9, a thrust bearing 20, a conical cap 11, and sieving blades 12. These components cooperate with each other to form a complete functional structure that integrates guiding descent, sieving, rotating crushing, and vibration refining.

[0028] The support ring 6 is the outer support component of the powder screening unit 5. It adopts a symmetrical structure that is narrow at the top and bottom and wide in the middle. Its outer wall is a standard cylindrical shape, which can keep it in close contact with the inner wall of the inner tank 4. Relying on the friction between the two, the support ring 6 can achieve a slow vertical drop inside the inner tank 4. This ensures that the powder screening unit 5 moves directionally along the axis of the inner tank 4, avoiding tilting or jamming during the drop. The controllable drop speed also provides sufficient time for the gradual screening and refining of the powder. At the same time, this symmetrical structure ensures that the powder screening unit 5 can maintain a stable assembly shape after the equipment is rotated multiple times, without affecting subsequent use. A horizontal plate 7 is fixedly installed in the middle of the support ring 6. The horizontal plate 7 is disc-shaped and coaxially arranged with the support ring 6. The two form a stable integral structure at their joint, providing a mounting base for the internal rotating parts and serving as a bearing surface for powder screening. Two arc-shaped powder screening holes 8 are provided at the joint position of the support ring 6 and the horizontal plate 7. The two powder screening holes 8 are centrally symmetrically distributed to provide a channel for the vertical passage of powder. Its arc-shaped structure can reduce the retention of powder when passing through and ensure that the powder falls smoothly.

[0029] A rotating platform 9 is installed at the center of the horizontal plate 7, and the two are rotatably connected by a thrust bearing 20. The thrust bearing 20 is embedded in the center mounting position of the horizontal plate 7, and retaining rings are provided on both its upper and lower end faces. The end face of the thrust bearing 20 and the retaining rings are fitted with a clearance fit, which not only limits the axial movement of the thrust bearing 20 during operation to prevent it from moving around, but also avoids the rotational jamming caused by an interference fit, ensuring the normal operation of the thrust bearing 20. The rotating platform 9 is snapped into the inside of the thrust bearing 20, and also maintains a clearance fit with the end face of the thrust bearing 20. Relying on the structural characteristics of the thrust bearing 20, the frictional resistance during the rotation of the rotating platform 9 is greatly reduced. At the eccentric position of the rotating platform 9, a pair of rotating shafts 10 are symmetrically arranged in the horizontal direction. Each rotating shaft 10 is connected to a conical cap 11. The pair of conical caps 11 are symmetrically arranged with the axis of the horizontal plate 7 as the center, and the cone apexes of the two are facing away from each other. The edge of the conical cap 11 is provided with several sieve blades 12 at equal intervals along the circumference. The sieve blades 12 are all arranged at an angle, and their ends extend to the area above the arc-shaped sieve hole 8, so that the falling powder can directly act on the surface of the sieve blades 12.

[0030] Under normal storage conditions, the sieving unit 5 relies on the friction with the inner wall of the inner tank 4 to stably remain above the powder inside the inner tank 4, without excessive compression of the powder, thus not affecting the normal sealed storage of the material, and preventing deformation of the sieving components due to long-term pressure. When the operator holds the rotating rod 13 and rotates the outer tank 3 180° around the support shaft 2, the inner tank 4 flips synchronously. Under the action of gravity, the vegetable oil powder inside the tank flows downward through the arc-shaped sieving holes 8 on the horizontal plate 7. The falling powder continuously impacts the inclined sieving blades 12 located above the sieving holes 8. The force generated by the powder flow is applied to the surface of the sieving blades 12, forming a resultant force that drives the conical cap 11 to rotate. The value of this resultant force is greater than the rotational resistance brought by the thrust bearing 20 to the rotating table 9 and the conical cap 11. Under the action of the difference between the force and the resistance, the conical cap 11 can smoothly rotate around the center of the rotating table 9. During the rotation, the sieving blades 12 continuously cut and disperse the passing powder, achieving preliminary refining of the powder.

[0031] During the rotation of the conical cap 11, because it is installed on the eccentric position of the rotating table 9 via the rotating shaft 10, the line of the rotating shaft 10 does not coincide with the center of gravity axis of the conical cap 11 itself. During rotation, regular eccentric vibration is generated. This vibration is transmitted to the horizontal plate 7 and the support ring 6 through the rotating table 9 and the thrust bearing 20, and then transmitted to the inner tank 4 by the support ring 6. It acts on the vegetable oil powder in the tank, causing the agglomerated powder to be further broken and loosened under the dual action of vibration impact and rotational shearing, improving the powder refinement effect and reducing the possibility of agglomeration from the root. The powder screening unit 5 adopts a completely symmetrical structure design. After the equipment completes a 180° flip and reset, when the flip operation is performed again, the powder screening unit 5 can maintain the original functional structure unchanged and continue to perform the complete process of powder falling, blade rotation, and eccentric vibration, realizing the effect of multiple flips and repeated refinement. It continuously turns and disperses the vegetable oil powder in the tank, maintains the loose state of the powder for a long time, and ensures the smoothness of the storage and discharge process.

[0032] Reference Figures 6-11 The powder screening unit 5, which is slidably installed inside the inner tank 4, is equipped with a matching falling and resetting component on the basis of the original screening and crushing structure. This component is integrated with the main structure of the powder screening unit 5, and two sets are symmetrically arranged with the central axis of the support ring 6 as the reference. The two sets of components have completely identical structures and functions complement each other, which is compatible with the overall symmetrical structure design of the powder screening unit 5, ensuring that the equipment can achieve stable anti-caking operation during the 180° bidirectional rotation process.

[0033] Each set of falling and resetting components mainly consists of a locking block 21, a pressure block 22, a pressure rod 23, a swing rod 24, a guide post 25, a guide ring 26, and a weak spring 27. These components are interconnected, forming a mechanical control structure triggered by pressure and reset by the spring, enabling precise control of the falling timing of the screening unit 5. A locking block 21 is rotatably mounted on the outer wall of the support ring 6. The locking block 21 adopts a symmetrical structure, with its rotation center located on the horizontal plane in the middle of the support ring 6, ensuring balanced force during rotation and maintaining the overall symmetrical assembly characteristics of the screening unit 5. The outer wall of the support ring 6 is provided with a locking groove. The spatial dimensions of the locking groove are adapted to the shape and rotation angle of the locking block 21. Under normal storage conditions and when no operation is triggered, the locking block 21 is completely housed in the locking groove and remains flush with the outer wall of the support ring 6. It does not protrude from the cylindrical outer surface of the support ring 6 and will not increase the contact friction between the support ring 6 and the inner wall of the inner tank 4. This ensures that the powder screening unit 5 can maintain a stable placement under normal conditions, without irregular slippage, and without affecting the normal sealing and storage function of the equipment.

[0034] A pair of pressure blocks 22 are correspondingly arranged on the horizontal plate 7. The pair of pressure blocks 22 are also symmetrically distributed around the axis of the support ring 6. The horizontal plate 7 has pressure grooves that match the shape of the pressure blocks 22. The pressure grooves provide vertical movement space for the pressure blocks 22, allowing the pressure blocks 22 to move vertically when subjected to external force, while restricting their horizontal swaying and ensuring the directional movement of the pressure blocks 22. Each pressure block 22 has a pressure rod 23 fixedly installed on the side facing the center of the horizontal plate 7, extending towards the horizontal plate 7. The pressure rod 23 moves up and down synchronously with the pressure block 22. The end of each pressure rod 23 away from the pressure block 22 abuts against a swing rod 24, forming a stable force transmission structure. One end of the swing rod 24 is hinged to the inside of the pressure groove of the horizontal plate 7. The hinge structure provides a reliable rotation fulcrum for the swing rod 24, ensuring that it can generate a stable swinging motion when subjected to force. The other end of the swing rod 24 abuts against the corresponding position of the locking block 21, realizing the force transmission from the pressure block 22 to the locking block 21.

[0035] Multiple guide posts 25 are fixedly installed at the bottom of the pressure block 22. A guide ring 26, matching the size and position of the guide posts 25, is installed inside the horizontal plate 7 at a corresponding position. The guide posts 25 and guide rings 26 form a sliding fit structure, providing precise guidance for the vertical movement of the pressure block 22, preventing the pressure block 22 from shifting or jamming during pressing and resetting, and ensuring its movement trajectory remains vertical. Multiple weak springs 27 are abutting between the horizontal plate 7 and the pressure block 22. The weak springs 27 are evenly distributed at the bottom of the pressure block 22. When no external pressure is applied, the weak springs 27 are in a naturally extended state, lifting the pressure block 22 to its initial position, maintaining the standby state of the falling and resetting assembly. The elastic force of the weak springs 27 is set to a moderate value, requiring only a small external pressure to compress them. Furthermore, after the external pressure is removed, they can quickly push the pressure block 22 back to its original position, achieving automatic resetting of the assembly.

[0036] The surface of the locking block 21 is provided with symmetrical inclined grooves 28. The end of the swing rod 24 is movably abutted against the inside of the inclined groove 28. The inclination angle of the inclined groove 28 is adapted to the swing trajectory of the swing rod 24. When the swing rod 24 rotates around the hinge point, its end can slide smoothly along the inclined groove 28, converting the swing force of the swing rod 24 into torque that drives the locking block 21 to rotate around its own rotation center, realizing efficient force transmission and smooth conversion of motion mode. When the equipment is operated and rotated 180°, the vegetable oil powder in the inner tank 4 changes position and is above the powder screening unit 5. The gravity of the powder itself will form a continuous downward pressure, which directly acts on the surface of the pressure block 22 on the horizontal plate 7. Under the pressure of the powder, the pressure block 22 overcomes the elastic force of the weak spring 27 and moves downward along the guide ring 26, simultaneously driving the pressure rod 23 to press down. The pressure rod 23 pushes the swing rod 24 that it abuts to rotate around the hinge point. The end of the swing rod 24 slides along the inclined groove 28 of the locking block 21, thereby driving the locking block 21 to rotate around its rotation center at a certain angle.

[0037] At this time, the upper part of the locking block 21 rotates out from the locking groove of the support ring 6, forming a wedge-shaped locking structure. This wedge-shaped structure protrudes from the outer wall of the support ring 6, forming additional contact pressure with the inner wall of the inner tank 4, significantly increasing the friction between the support ring 6 and the inner wall of the inner tank 4. Combined with the basic friction between the support ring 6 and the inner wall of the inner tank 4, only a small pressure is needed from the powder to the pressure block 22 to make the locking block 21 swing slightly, forming a sufficient blocking effect, effectively preventing the powder screening unit 5 from sliding downwards when the powder has not been screened and fallen. As the screening operation continues, most of the powder passes through the screening holes 8 in sequence to complete the fine processing and falls below the screening unit 5. The powder pressure acting on the pressure block 22 gradually decreases. When the pressure is less than the elastic force of the weak spring 27, the weak spring 27 begins to extend and reset, pushing the pressure block 22 to move upward along the guide column 25 to the initial position. The pressure rod 23 rises synchronously, releasing the downward pressure on the swing rod 24. The swing rod 24 rotates in the opposite direction to reset without external pressure, and its end retracts along the inclined slide groove 28, no longer applying rotational torque to the locking block 21. The locking block 21 then rotates in the opposite direction to return to the center and is re-stored in the locking groove of the support ring 6, restoring its flush state with the outer wall of the support ring 6.

[0038] After the locking block 21 returns to its original position, the additional friction between the support ring 6 and the inner wall of the inner tank 4 disappears, leaving only the basic contact friction. The obstruction is removed, and the sieving unit 5 can smoothly complete subsequent reset or position adjustment actions based on its own weight and the state of the material inside the tank. This avoids problems such as incomplete sieving and component collisions caused by the sieving unit 5 prematurely sliding down before the powder has been fully sieved and fallen. The overall falling reset assembly adopts a symmetrical upper and lower structure design consistent with the main body of the sieving unit 5. When the equipment is rotated 180° to return to its original position or reversed, the other set of falling reset components, originally on the opposite side, will bear the powder pressure and complete the complete action process of triggering, locking, and resetting according to the same mechanical transmission logic. The two sets of components work alternately to ensure that the equipment can stably and accurately control the falling timing of the sieving unit 5 during multiple, bidirectional flipping operations, continuously ensuring the fine sieving and anti-caking effect of the vegetable oil powder, further improving the stability and reliability of the equipment operation.

[0039] The working principle of this invention is as follows: The equipment is built on a stable foundation by a bracket 1 and a support shaft 2. The outer tank 3 and the inner tank 4 form a double-layer sealed structure. The inner tank 4 lid 14 ensures that the vegetable oil powder is isolated from external moisture and impurities, thus achieving sealed storage. The rotating rod 13 of the outer tank 3 is an operation triggering component. The user can start the anti-caking operation process by holding the rotating rod 13 and rotating the outer tank 3 180°. After being flipped, the inner tank 4 flips synchronously with the outer tank 3. On the one hand, the inner tank 4 slides vertically down the limiting rib 17 on the inner wall of the outer tank 3 under its own gravity until the sliding plate 18 hits the limiting ring 19 and generates vibration, which initially loosens the clumps of powder in the tank. On the other hand, the sieving unit 5 in the inner tank 4 responds synchronously. The sieving unit 5, which was originally located above the powder, is triggered by the gravity of the powder. The powder falls through the arc-shaped sieving hole 8 at the junction of the support ring 6 and the horizontal plate 7, impacting the sieving blades 12 and generating a resultant force. This resultant force overcomes the rotational resistance brought by the thrust bearing 20 and drives the eccentrically mounted conical cap 11 to rotate. The sieving blades 12 cut and refine the powder, and at the same time, the vibration generated by the eccentric rotation of the conical cap 11 further breaks up the clumps of powder. During this process, the falling and resetting component of the powder screening unit 5 works simultaneously: the powder pressure acts on the pressure block 22, causing the pressure rod 23 to push the swing rod 24 to rotate, which drives the locking block 21 to rotate and extend through the inclined slide groove 28, forming a wedge structure, increasing the friction with the inner tank 4, and preventing the powder screening unit 5 from falling prematurely; after most of the powder has been screened and fallen, the pressure on the pressure block 22 decreases, and it resets under the action of the weak spring 27, the locking block 21 returns to its original position, and the powder screening unit 5 can smoothly complete the subsequent actions. Since the powder screening unit 5 and the falling and resetting component are both symmetrical structures, when the equipment is flipped multiple times, the relevant structures can be repeatedly triggered to achieve repeated tumbling and refining of the powder, continuously ensuring the anti-caking effect. Finally, through the linkage and cooperation of various structures, the dual functions of sealed storage and anti-caking of the vegetable oil powder are achieved.
