Description

Technical Field

[0001] This utility model relates to the field of lutein technology, and in particular to a filtration and sieving device for producing lutein powder. Background Technology

[0002] Lutein powder is a fat-soluble carotenoid extracted from natural plants and is widely used in food additives, health products, and pharmaceuticals. Due to its unique molecular structure, the powder particles are prone to aggregation and are lightweight with strong adhesive properties, making them susceptible to clumping during production and storage, affecting the product's flowability and uniformity. Therefore, fine sieving is necessary to ensure that the powder particle size meets industry standards. However, existing lutein powder production filtration and sieving equipment still suffers from poor sealing, failing to effectively isolate sunlight and oxygen, and exhibiting slow sieving efficiency.

[0003] Therefore, it is essential to invent a filtration and sieving device for producing lutein powder. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a lutein powder production filtration and sieving device, which solves the problems of poor sealing, ineffective isolation of sunlight and oxygen, and slow sieving efficiency found in existing lutein powder production filtration and sieving devices. The lutein powder production filtration and sieving device includes a supporting base plate, a supporting frame, a sieving section, a finished product tank, a sieving structure, a sealing cover, and a lifting structure. The supporting base plate is fixedly installed on the ground, and the supporting frame is fixedly installed in the middle position on the surface of the supporting base plate. The sieving section is rotatably installed inside the supporting frame. The finished product tank is slidably installed inside the sieving section, and the sieving structure engages inside the sieving section. The sealing cover is engaged above the sieving section. The sealing cover is suspended above the sieving section by the lifting structure.

[0005] The screening section includes a screening chamber, a closed bottom plate, a swing connecting platform, a meshing rack, and a swing traction rope. The closed bottom plate is fixedly installed at the bottom of the screening chamber, and the swing connecting platform is fixedly installed below the closed bottom plate. The meshing rack is fixedly installed on the inner wall of the screening chamber, and the swing traction rope is fixedly installed at both ends of the closed bottom plate and installed on the roof of the building via a traction motor.

[0006] The screening structure includes closed side plates, counterweight support frames, internal support nets, external support nets, and meshing gears. Two sets of closed side plates are used, and counterweight support frames are fixedly installed on the outer side of each closed side plate. The internal support nets and external support nets are fixedly installed inside the two sets of counterweight support frames, and the meshing gears are fixedly installed on the outer side of the two sets of closed side plates and mesh with the meshing rack.

[0007] The screening section is a long, rectangular metal box, and it can repeatedly tilt up and down at both ends by the pull of the swinging traction ropes at both ends, with the swinging connecting platform as the fulcrum. The overall movement trajectory of the screening section is consistent with that of a seesaw. When the screening section tilts up and down, the meshing rack also performs corresponding actions.

[0008] When the screening structure tilts and falls within the screening zone, it rolls repeatedly on the meshing rack under gravity until it impacts the inner walls at both ends of the screening zone. The closed side plate can be detached from the counterweight support frame for feeding lutein powder. The counterweight support frame uses two sets of ring-shaped steel metal structures, and the outside of the counterweight support frame is wrapped with a protective rubber pad. The inner and outer support nets use two sets of concentric steel metal meshes, with a gap between them. This gap allows for the placement of filter screens with different pore sizes as needed.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The design of the screening chambers in this utility model, with the screening chamber and sealing cover forming a closed working cavity, effectively prevents powder scattering. Reciprocating oscillation is achieved through the fulcrum design of the swing connecting table and the traction of the swing traction rope. The oscillation is converted into automatic rolling screening action of the screening structure by the meshing of the inner wall rack and gears of the screening structure. Simultaneously, the closed bottom plate provides stable support and supports the finished product trough. This ensures the airtightness of the screening operation and achieves efficient power transmission, enabling the entire screening process to be completed automatically in a controlled environment.

[0011] 2. The sieving structure of this utility model forms an independent sieving chamber through a closed side plate, and consists of a replaceable double-layer filtration system composed of an internal support mesh and an external support mesh. With the cooperation of meshing gears and meshing racks within the sieving section, the equipment's oscillation motion is transformed into autonomous rolling sieving action. Simultaneously, the counterweight support frame generates anti-clogging vibration through periodic impacts, and the rubber coating layer also serves as a buffer and noise reduction function. This structure combines three major advantages: high-efficiency filtration, automatic anti-clogging, and convenient maintenance, significantly improving the sieving efficiency and production convenience of lutein powder.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0018] As attached Figure 1 To be continued Figure 3 As shown.

[0019] This utility model provides a filtration and sieving device for producing lutein powder, comprising a supporting base plate 1, a supporting frame 2, a sieving section 3, a finished product tank 4, a sieving structure 5, a sealing cover 6, and a lifting structure 7. The supporting base plate 1 is fixedly installed on the ground, and the supporting frame 2 is fixedly installed at the middle position on the surface of the supporting base plate 1. The sieving section 3 is rotatably installed inside the supporting frame 2. The finished product tank 4 is slidably installed inside the sieving section 3, and the sieving structure 5 is engaged inside the sieving section 3. The sealing cover 6 is engaged above the sieving section 3. The sealing cover 6 is suspended above the sieving section 3 by the lifting structure 7.

[0020] The screening section 3 includes a screening chamber 31, a closed bottom plate 32, a swing connecting platform 33, a meshing rack 34, and a swing traction rope 35. The closed bottom plate 32 is fixedly installed at the bottom of the screening chamber 31, and the swing connecting platform 33 is fixedly installed below the closed bottom plate 32. The meshing rack 34 is fixedly installed on the inner wall of the screening chamber 31, and the swing traction rope 35 is fixedly installed at both ends of the closed bottom plate 32 and installed on the roof of the building through a traction motor.

[0021] The screening structure 5 includes a closed side plate 51, a counterweight support frame 52, an internal support net 53, an external support net 54, and a meshing gear 55. Two sets of closed side plates 51 are used, and a counterweight support frame 52 is fixedly installed on the outer side of each closed side plate 51. The internal support net 53 and the external support net 54 are fixedly installed inside the two sets of counterweight support frames 52, and the meshing gear 55 is fixedly installed on the outer side of the two sets of closed side plates 51 and meshes with the meshing rack 34.

[0022] The screening section 3 is a long strip of metal box, and the screening section 3 can repeatedly tilt up and down at both ends by the pull of the swing traction ropes 35 at both ends, with the swing connecting platform 33 as the fulcrum; the overall movement trajectory of the screening section 3 is consistent with that of a seesaw; when the screening section 3 tilts up and down, the meshing rack 34 also makes corresponding movements.

[0023] When the screening structure 5 tilts and falls in the screening section 3, it rolls repeatedly on the meshing rack 34 under gravity until it hits the inner walls at both ends of the screening section 3. The closed side plate 51 can be disassembled from the counterweight support frame 52 for feeding lutein powder. The counterweight support frame 52 adopts two sets of ring-shaped steel metal structures, and the outside of the counterweight support frame 52 is wrapped with a protective rubber pad. The inner support net 53 and the outer support net 54 adopt two sets of concentric steel metal meshes, and there is a gap between the inner support net 53 and the outer support net 54. The gap between the inner support net 53 and the outer support net 54 can accommodate filter screens of different pore sizes as needed.

[0024] This equipment uses the alternating traction of the swinging traction rope 35 to drive the screening section 3 to swing in a seesaw-like manner with the swinging connecting table 33 as the fulcrum. The meshing rack 34 on the inner wall transmits the swing displacement to the meshing gear 55 of the screening structure 5, which is converted into the autonomous rolling of the screening structure, forming a unique mechanical self-propelled screening state.

[0025] The powder-loading sieving structure 5 rotates, filtering the powder through a sieve held between an internal support mesh 53 and an external support mesh 54. Periodic impacts from the counterweight support frame 52 generate vibrations, which, combined with a rubber buffer layer, prevent filter clogging and reduce noise. The sieved powder is then guided through a closed bottom plate 32 to the finished product tank 4 for efficient collection.

[0026] The sieving chamber 31 and the sealing cover 6 form a fully enclosed space to prevent powder spillage. The support frame 2 and the support base plate 1 ensure operational stability, while the removable enclosed side plate 51 facilitates maintenance. This device integrates mechanical automation and modular design to achieve clean and efficient sieving of lutein powder.

[0027] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
