[0002] As a traditional tonic, the soaking and impurity separation processes are crucial in the processing of bird's nest. Traditional methods of soaking and separating bird's nest mainly rely on manual operation, which is not only inefficient but also makes it difficult to ensure the consistency of soaking results and the thoroughness of impurity separation.
[0003] While some existing mechanized devices can improve production efficiency to some extent, most suffer from problems such as complex structure, limited functionality, incomplete impurity separation, and easy damage to bird's nests. For example, some devices cannot effectively remove light impurities during the soaking process, and in the impurity separation stage, they struggle to separate heavy impurities from the bird's nest, resulting in inconsistent product quality and failing to meet market demand for high-quality bird's nest products. Therefore, designing a device with a reasonable structure that can achieve efficient soaking of bird's nests and precise impurity separation is of significant practical importance.

[0025] Example 1
[0026] like Figures 1-3 As shown:
[0027] A device for soaking and separating bird's nest includes a cylindrical soaking vessel 1 for holding bird's nest. The top surface of the soaking vessel 1 is provided with a cover plate 11, and a discharge port is provided on the cover plate 11. The bottom of the soaking vessel 1 is a conical structure 12 to facilitate material discharge, and a discharge port 13 is provided at the bottom of the conical structure 12.
[0028] The soaking vessel 1 is connected to a purified water supply mechanism, which includes a purified water storage tank 2, a delivery pump 21, and a supply pipe 22. The inlet of the delivery pump 21 is connected to the purified water storage tank 2, and the two ends of the supply pipe 22 are connected to the water inlet of the soaking vessel 1 and the outlet of the delivery pump 21, respectively. A supply control valve 23 is installed on the supply pipe 22. Soaking the bird's nest in room temperature purified water allows it to gradually absorb water and expand to a suspended state.
[0029] The soaking container 1 is equipped with a stirring mechanism, which includes a stirring motor 31 installed above the cover plate 11. The output shaft of the stirring motor 31 is connected to a stirring shaft 32 extending into the inside of the soaking container 1. Stirring blades 33 are installed on the stirring shaft 32. The stirring blades 33 are covered with a rubber protective layer 34 to avoid structural damage to the bird's nest.
[0030] The foaming vessel 1 is also equipped with an air blowing mechanism, which includes a mesh air distribution pipe 41 installed inside the foaming vessel 1 and near the bottom. The center of the air distribution pipe 41 serves as a rotating seat at the bottom of the stirring shaft 32. Multiple aeration heads 42 are installed on the air distribution pipe 41. The air distribution pipe 41 is connected to an air storage tank 44 through an air supply pipe 43 outside the foaming vessel 1. An air compressor 45 is installed on the air storage tank 44, and an air flow regulating valve 46 is installed on the air supply pipe 43.
[0031] The synergistic effect of the stirring and aeration mechanisms effectively promotes the floating of light impurities. The rotation of the blades in the stirring structure disperses bird's nest or impurities, breaking up the agglomeration and sinking of light impurities. The tiny bubbles generated by the aeration head 42 of the aeration mechanism can be adsorbed onto the surface of light impurities, causing them to float rapidly to the liquid surface. During the rise of the bubbles, they push the surrounding water to form an upward microjet, disrupting the laminar flow of the liquid and generating local turbulence, which can carry light impurities towards the liquid surface. A large number of bubbles gather on the liquid surface to form a foam layer, in which light impurities are trapped, forming a high-concentration impurity layer, which is convenient for collection and removal by the net 5.
[0032] like Figure 1 and Figure 2 As shown, a semi-cylindrical scooping net 5 with a water-filtering hole is installed on the stirring shaft 32. The scooping net 5 is positioned at the liquid level in the foaming vessel 1. The semi-cylindrical scooping net 5 has an axial scooping opening 51 on its outer circumference based on a cylindrical structure. The end of the scooping net 5 near the stirring shaft 32 is connected to a mounting ring 52 sleeved on the stirring shaft 32, and the end of the scooping net 5 away from the stirring shaft 32 is close to the inner wall of the foaming vessel 1. The mounting ring 52 can be connected to the stirring shaft 32 by welding or other fixing methods, or it can be detachably connected to the stirring shaft 32 by locking bolts.
[0033] In this embodiment, there are two scooping nets 5. From a top-down perspective, the two scooping nets 5 are symmetrical about the axis of the stirring shaft 32, ensuring that they scoop in the same direction during rotation. If three scooping nets 5 are used, they are evenly distributed in a 120-degree ring around the axis of the stirring shaft 32. The number of scooping nets 5 is not limited, but their scooping directions remain consistent.
[0034] By setting up a centrally symmetrical scooping net 5, a regular geometric array can be formed on the liquid surface. Light impurities reach the liquid surface with the upward flow generated by blowing or stirring, and are simultaneously intercepted by the symmetrically distributed scooping net 5, which avoids the accumulation of impurities in local areas due to uneven flow field and improves capture efficiency. It can balance the fluid forces in all directions, suppress liquid surface swirling, and ensure that impurities remain stably in the area of scooping net 5.
[0035] The discharge port 13 of the foaming vessel 1 is connected to a flotation mechanism via a gradually expanding discharge pipe 14, and a discharge control valve 15 is installed on the discharge pipe 14. The flotation mechanism includes a flotation cell 6, with a slow-speed water flow drive mechanism connected upstream of the flotation cell 6 and a material collection mechanism connected downstream of the flotation cell 6.
[0036] The gradually expanding discharge pipe 14 can reduce the discharge speed of bird's nest and impurities, making it easier for heavy impurities gathered at the bottom of the soaking vessel 1 to be discharged first and reach the flotation cell 6, while the bird's nest is discharged later with the pure water; the low-speed fluid can reduce the disturbance to the flow field in the soaking vessel 1, and avoid the re-suspension of separated heavy impurities or a small portion of light impurities that have not been retrieved during the transportation process; it provides a stable low-speed feed for the flotation mechanism, which facilitates the full floating or settling of impurities in the flotation cell 6, and the low-speed fluid can prolong the residence time and promote the separation of impurities; it avoids the boundary layer separation of the fluid that is prone to forming eddy zones if the pipe is suddenly expanded, ensuring that the flow field in the flotation cell 6 is uniform and stable, and reducing the dead zones of impurity retention or deposition.
[0037] The bottom surface of the flotation cell 6 is set as a downward slope 61 from upstream to downstream, with an inclination angle of 10°. The interior of the flotation cell 6 is provided with a transverse intercepting net 62 installed on the top surface near the downstream position. The upstream side wall of the flotation cell 6 has a feed inlet 63 connected to the discharge pipe 14 and a water inlet 64 connected to the slow water flow drive mechanism. The downstream side wall of the flotation cell 6 has a discharge outlet 65 connected to the collecting mechanism. The lowest point of the slope 61 is provided with a slag discharge outlet 66.
[0038] like Figure 1 and Figure 3 As shown, the transverse intercepting net 62 is a deflected semi-cylindrical structure, with the bottom edge of its filter media inlet being higher than the lowest edge of the main body. An inclined overflow plate 621 is provided at the filter media inlet, and the overflow plate 621 is flush with the liquid surface.
[0039] A guide plate 611 is installed on the surface of the slope 61 near the upstream water inlet 64, and the guide plate 611 is inclined upward at 20 degrees. In order to further prevent the liquid conveyed through the water inlet 64 from generating eddies, a longitudinally arranged diverter plate 612 can also be installed on the guide plate 611.
[0040] The slow-speed water flow drive mechanism includes a water supply pipe 71 installed upstream of the flotation cell 6. The water supply pipe 71 is connected to the pure water storage tank 2 via a water pump 72. A water flow regulating valve 73 is installed on the water supply pipe 71. The water inlet 64 of the water supply pipe 71 is located below the feed inlet 63. The slow-speed water flow drive mechanism outputs a water flow with a velocity of 0.05-0.1 m / s.
[0041] The flotation cell 6 contains purified water that has been pre-injected by a slow-flow-driven mechanism.
[0042] Through the synergistic effect of the bottom slope 61 of the flotation cell 6, the guide plate 611, and the slow water flow drive mechanism, efficient stratification of light impurities, heavy impurities, and bird's nest can be achieved.
[0043] Heavy impurities tend to sink under gravity, and the inclined slope 61 provides them with the momentum to slide down the slope, accelerating sedimentation and separation. Light impurities easily float to the surface due to buoyancy in the water flow. The weak upward water flow generated by the slow-moving water flow drive mechanism helps the light impurities float stably to the surface. A transverse intercepting net 62 is set downstream of the flotation tank 6. The light impurities floating on the surface are carried by the water flow to the transverse intercepting net 62 and are then scooped into the net, completing the separation. The soaked bird's nest is in a suspended state in the slow-moving water flow, neither sinking quickly nor floating to the surface. Instead, it is guided by the guide plate 611 and slowly moves downstream with the water flow.
[0044] The guide vane 611 transforms turbulent water flow into regular laminar flow by changing the direction of the water flow, avoiding the generation of local eddies and preventing impurities from remixing under the action of eddies. In laminar flow, substances of different densities move independently in the water flow, each following the laws of gravity and buoyancy, thus achieving stratification.
[0045] The slow-flow mechanism generates a moderate water speed, which moves the bird's nest slowly without interfering with the settling of heavy impurities or the rising of light impurities. At the same time, the slight upward force generated by the slow water flow can offset some of the downward speed of heavy impurities, allowing them to move downstream and settle, preventing them from depositing too quickly at the bottom of slope 61 and affecting subsequent cleaning.
[0046] The material collection mechanism includes a material collection box 8, which is connected to the discharge port 65 downstream of the flotation cell 6 via a discharge pipe 81. The discharge port 65 is located above the slag discharge port 66. A discharge control valve 811 is installed on the discharge pipe 81 to control its opening and closing. A filter screen 82 is installed inside the material collection box 8 to separate the bird's nest from the purified water.
[0047] A screw feeding mechanism 9 is installed below the flotation cell 6. The slag discharge port 66 is connected to the feed end of the screw feeding mechanism 9 through the slag discharge pipe 67. The discharge end of the screw feeding mechanism 9 is connected to the slag collection box 91. A slag discharge control valve 671 is installed on the slag discharge pipe 67.
[0048] The flow rate of pure water output from the water inlet 64 of the slow-speed water flow drive mechanism is equal to the sum of the flow rates from the outlet 65 and the slag discharge outlet 66.
[0049] Work process:
[0050] First, inject room temperature purified water into the soaking container 1 through the purified water supply mechanism, open the feeding port on the cover plate 11, and put the dry bird's nest into the soaking container 1. After the dry bird's nest is put into the water, it will initially sink to the bottom of the container 1 due to its slightly higher density. However, after absorbing water, its volume expands, its density gradually decreases, and it begins to float slowly. The fully soaked bird's nest will be in a suspended state.
[0051] Next, the stirring mechanism pre-stirs for 1-3 minutes, maintaining a low stirring speed of 30-60 r / min. The aeration mechanism injects microbubbles of 50-200 μm into the soaking vessel 1 through the aeration head 42 at an output air velocity of 0.1-0.3 m³ / (m²·min). As the bird's nest soaks, heavy impurities settle to the discharge port 13, while light impurities float to the surface under the action of the stirring and aeration mechanisms, leaving the bird's nest suspended in the pure water. The net 5, driven by the stirring mechanism, scoops and separates the light impurities.
[0052] Pure water is pre-injected into the flotation cell 6 of the flotation mechanism through a slow water flow drive mechanism, and the pure water level is level with the lowest point of the transverse intercepting net 62.
[0053] Then, the discharge control valve 15 on the discharge pipe 14 is opened, and the material in the soaking vessel 1 is transported to the flotation cell 6 through the discharge pipe 14. The material is mixed with the pure water pre-injected into the flotation cell 6. At the same time, the water pump 72 slowly injects into the flotation cell 6. After the light impurities, heavy impurities and bird's nest reach the flotation cell 6, they are separated into layers. The discharge control valve 811 and the slag discharge control valve 671 are opened. The light impurities gradually float to the surface and are blocked and scooped up by the transverse intercepting net 62. The bird's nest reaches the discharge port 65 and enters the collection box 8. The heavy impurities reach the slag discharge port 66 and are discharged. Finally, the heavy impurities enter the slag collection box 91 through the screw feeding mechanism 9, completing the soaking of bird's nest and the separation of impurities.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
