Description

Technical Field

[0001] This invention relates to the field of bird's nest impurity separation technology, and in particular to a bird's nest impurity separation device and separation method. Background Technology

[0002] The impurity removal process during bird's nest processing directly determines the final quality and commercial grade of the product. Raw bird's nests (raw bird's nests) usually contain various foreign objects such as bird feathers, down feathers, eggshell fragments, black spots (impurities), and sand, which must be thoroughly removed during processing to meet edible standards.

[0003] Currently, while some mechanically assisted impurity removal devices have emerged in existing technologies, significant technical bottlenecks remain in practical applications. Firstly, some devices rely solely on a single stirring device to rotate the water, using centrifugal force to float lightweight impurities. However, this method lacks an active capture mechanism for floating impurities; they primarily rely on passive drift to the collection area, resulting in some lightweight feathers remaining on the surface for extended periods, leading to low separation efficiency. Secondly, existing equipment typically operates under fixed and monotonous conditions, making it difficult to adapt to the processing needs of different grades of bird's nest (such as whole bird's nests and bird's nest strips with high impurity content). Fixed rotation speeds can easily cause top-grade bird's nests to break due to excessive mechanical shearing force, or the rotation speed may be too low to process raw materials with high impurity content. Furthermore, traditional filter structures are mostly static, easily creating "dead zones" in rotating water flow, hindering continuous impurity collection.

[0004] Therefore, in view of the problems of low impurity removal efficiency, poor adaptability and easy damage to bird's nest in the above-mentioned existing technologies, it is necessary to propose an impurity separation device and method with active capture function, adjustable working conditions and effective protection of the integrity of bird's nest. This is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To alleviate the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0006] This invention provides a device for separating impurities from bird's nest, comprising: Base tube; Turbine propellers installed inside the base tube; Microporous aeration discs are installed at the bottom of the base cylinder; And a filter installed inside the base cylinder and above the water surface; It also includes a transmission mechanism configured to drive the spoiler and the filter to rotate synchronously in opposite directions.

[0007] Furthermore, The filter is rotatably mounted on the upper part of the base cylinder via the outer ring body; The outer wall of the outer ring body is provided with an external toothed ring; The transmission mechanism includes a drive wheel coaxially connected to the spoiler, a driven wheel driven by the drive wheel, a trapezoidal wheel column coaxially connected to the driven wheel, a corresponding wheel cooperating with the trapezoidal wheel column, and a side gear driven by the corresponding wheel. The side gear is mounted on the vertical shaft; Corresponding gears are mounted on a splined shaft via splines; The splined shaft is connected to the vertical shaft via a cross coupling and a commutator. The side gear meshes with the external gear ring.

[0008] Furthermore, The filter includes a filter frame and two integrally formed corrugated plate sections. The two corrugated plate sections are arranged symmetrically on both sides of the filter frame. The corrugated plate sections have a curved guiding structure to intercept and guide floating impurities to gather into the filter frame.

[0009] Furthermore, It also includes a speed control component, which is used to adjust the contact position between the co-position wheel and the trapezoidal wheel column to steplessly adjust the speed ratio between the filter and the turbulence propeller.

[0010] Furthermore, The speed control assembly includes a stepper motor, a screw driven by the stepper motor, a positioning seat threadedly connected to the screw, and a guide post arranged parallel to the screw; The positioning seat is slidably sleeved on the guide post; One side of the positioning seat extends to form a support ear plate that is arranged vertically opposite to the other; The upper and lower end faces of the corresponding wheel are rotatably connected to the support ear plate, respectively.

[0011] Furthermore, The spoiler is an anchor-type blade, and its horizontal cross-sectional diameter is close to the inner diameter of the base tube.

[0012] Furthermore, The filter is detachably mounted on the base cylinder via a plug-in connection, specifically as follows: The outer ring has two sets of oppositely arranged side ears, and the ends of the two sets of corrugated plates are respectively inserted into the slots opened on the side ears.

[0013] Furthermore, A guide slope is provided at the connection between the side ear and the corrugated plate, and the guide slope and the arc surface of the corrugated plate transition smoothly.

[0014] Furthermore, A flow channel is provided at the connection between the filter frame and the corrugated plate section to connect the water flow inside and outside the corrugated plate section.

[0015] A method for separating impurities from bird's nest includes the following steps: S1. Place the bird's nest to be processed into the base cylinder and pour in low-temperature purified water; S2. Set the initial speed of the turbulence propeller according to the grade of bird's nest, and set the speed ratio between the filter and the turbulence propeller through the speed control component. S3. Start the equipment to make the turbulence impeller and the filter rotate synchronously in opposite directions, and at the same time start the microporous aeration disc to generate microbubbles. S4. The wave plate section of the filter, which uses rotating water flow and counter-rotating filter, intercepts and collects floating light impurities. S5. After stopping the machine, remove the cleaned bird's nest.

[0016] The beneficial effects of the equipment and method for separating impurities in bird's nests in this invention are analyzed as follows: The present invention provides a device for separating impurities in bird's nest, including a base cylinder, a turbulence propeller disposed inside the base cylinder, a microporous aeration disc disposed at the bottom of the base cylinder, and a filter disposed inside the base cylinder and above the water surface; it also includes a transmission mechanism configured to drive the turbulence propeller and the filter to rotate synchronously in opposite directions.

[0017] First, the turbulence propeller and the filter are driven to rotate synchronously in opposite directions by the transmission mechanism. The floating impurities are transported in an orderly manner by the forward rotating water flow, and actively captured by the reverse rotating filter. This changes the traditional equipment's reliance on the passive drift of impurities and significantly improves the processing efficiency of light impurities such as swallow feathers.

[0018] Secondly, by adjusting the contact position between the corresponding wheel and the trapezoidal wheel column using a speed-regulating component, stepless adjustment of the speed ratio between the turbulence propeller and the filter is achieved. Operators can flexibly set the operating conditions according to the grade of bird's nest, ensuring the impurity removal effect while minimizing mechanical damage to top-grade bird's nests.

[0019] Furthermore, by using anchor-type paddles in conjunction with microporous aeration discs, a large-area overall flow is used instead of localized jets. Combined with the gentle peeling effect of microbubbles, impurities can be removed without damaging the structure of the swallow silk fibers, avoiding the hidden damage caused by high-pressure washing or strong agitation.

Detailed Implementation

[0023] like Figures 1 to 7As shown, this invention provides a device for separating impurities from bird's nest, including a base cylinder 100, a turbulence propeller 200, a microporous aeration disc 300, and a filter 400. The base cylinder 100 serves as the main container of the entire device, holding the bird's nest to be processed and water. The turbulence propeller 200 is disposed inside the base cylinder 100 to agitate the water flow and create a rotating flow field. The microporous aeration disc 300 is fixedly installed at the bottom of the base cylinder 100 to generate a large number of microbubbles. These bubbles can penetrate into the gaps in the bird's nest fibers, peeling off attached feathers, black spots, and other impurities and carrying them to the surface. The filter 400 is disposed at the top of the base cylinder 100, specifically for intercepting and collecting lightweight impurities floating on the water surface. Crucially, this device is also equipped with a precision transmission mechanism 500, configured to drive the turbulence propeller 200 and the filter 400 to rotate synchronously in opposite directions. This reverse rotation design allows the rotating water flow to push impurities toward the central area, while the reverse rotating filter 400 actively captures these impurities like a "sweeping arm," thereby greatly improving the impurity removal efficiency.

[0024] Based on the above, the filter 400 is rotatably mounted on the upper part of the base cylinder 100 via an outer ring body 600. An external toothed ring 610 is provided on the outer wall of the outer ring body 600. The transmission mechanism 500 specifically includes: a drive wheel 510 coaxially connected to the spoiler 200, which is connected to the driven wheel 520 via a belt or chain. The driven wheel 520 is coaxially connected to a vertically arranged trapezoidal wheel post 530, the side of which has a tapered friction surface. A corresponding wheel 540 cooperates with the trapezoidal wheel post 530, which is splined onto a splined shaft 570. The upper part of the splined shaft 570 is connected to the vertical shaft 560 at the lower part of the side gear 550 via a cross coupling and a reversing device. The cross coupling and reversing device are prior art and are omitted in the accompanying drawings. When the spoiler 200 is driven to rotate by the motor, the power is transmitted to the trapezoidal wheel column 530 via the driving wheel 510 and driven wheel 520, and then to the corresponding wheel 540 through friction. The power of the corresponding wheel 540 is transmitted to the vertical shaft 560 via the commutator, driving the side gear 550 to rotate. Since the side gear 550 meshes with the external gear ring 610 on the outer ring body 600, it ultimately drives the entire filter 400 to rotate. The presence of the commutator ensures that the rotation direction of the filter 400 is opposite to that of the spoiler 200.

[0025] The filter 400 comprises a filter frame 410 with a filter screen at the bottom and two sets of corrugated plate sections 420 integrally formed on both sides thereof. These two sets of corrugated plate sections 420 are arranged in a centrally symmetrical manner, and their overall structure is a curved guiding structure. When floating impurities on the water surface come into contact with the corrugated plate sections 420, this curved structure not only effectively intercepts the impurities but also guides them smoothly along the curved surface to the central area of ​​the filter frame 410, preventing impurities from accumulating or escaping at the edges of the corrugated plate sections 420, thus ensuring the high efficiency and continuity of impurity collection.

[0026] To adapt the equipment to the processing requirements of different grades of bird's nest, this equipment is also equipped with a speed regulating component 700. The core function of this speed regulating component 700 is to adjust the contact position between the corresponding wheel 540 and the trapezoidal wheel column 530. Since the diameter of the trapezoidal wheel column 530 gradually changes along its axial direction, changing the contact point between the corresponding wheel 540 and it allows for stepless adjustment of the speed ratio between the two, thereby achieving precise and continuous control of the speed ratio between the filter 400 and the turbulence propeller 200.

[0027] The speed control assembly 700 includes a stepper motor 710, a screw 720 driven by the stepper motor 710, a positioning seat 730 threadedly connected to the screw 720, and a guide post 740 parallel to the screw 720. The positioning seat 730 is slidably fitted onto the guide post 740 to ensure its linear movement. A support ear plate extends from one side of the corresponding wheel 540, with opposing upper and lower support plates; the support ear plate is rotatably connected to the positioning seat 730, and the spline shaft 570, screw 720, and guide post 740 are all parallel to the side of the trapezoidal wheel post 530, ensuring that the corresponding wheel 540 is always connected to the trapezoidal wheel post 530 in a transmission manner. When the stepper motor 710 starts, it drives the screw 720 to rotate, thereby driving the positioning seat 730 to move precisely linearly along the guide post 740. The movement of the positioning seat 730 directly changes the relative contact position between its internal co-position wheel 540 and the trapezoidal wheel column 530, thereby realizing the aforementioned stepless speed regulation function.

[0028] The turbulence impeller 200 in this equipment preferably adopts an anchor-type blade, characterized by a horizontal cross-sectional diameter very close to the inner diameter of the base cylinder 100. This design enables the water within the base cylinder 100 to circulate over a wide range at relatively low speeds, forming a stable rotating flow field. Simultaneously, the anchor-type blade generates minimal shear force, effectively preventing mechanical damage to the delicate bird's nest during stirring, making it particularly suitable for the delicate processing of high-value bird's nests.

[0029] For ease of cleaning and maintenance, the filter 400 is installed on the outer ring body 600 using a detachable plug-in method. Specifically, the outer ring body 600 has two sets of opposing side ears 620, each with a slot that matches the shape of the end of the corrugated plate 420. During installation, simply align the ends of the two sets of corrugated plate 420 and insert them into the corresponding slots to secure them; for cleaning, the reverse operation allows for quick and easy disassembly.

[0030] At the connection between the side ear portion 620 and the corrugated plate portion 420, a guide slope 630 is specially designed. This guide slope 630 smoothly transitions to the arc surface of the corrugated plate portion 420 itself. This design eliminates steps or sharp angles at the connection, allowing water flow and floating impurities to flow smoothly from the side wall of the base cylinder 100 to the corrugated plate portion 420, avoiding water flow turbulence or impurity stagnation caused by structural abrupt changes, and further optimizing the impurity collection path.

[0031] At the junction of the filter frame 410 and the corrugated plate section 420, a final flow channel 430 is provided. These final flow channels 430 are small holes or gaps that connect the water flow on both the inner and outer sides of the corrugated plate section 420. Their function is to balance the water pressure on both sides of the corrugated plate section 420, prevent the formation of a "dead water zone" in front of the corrugated plate section 420 due to excessive water pressure difference, and ensure that the water flow can continuously and stably pass through the corrugated plate section 420, thereby maintaining efficient impurity interception and guidance functions.

[0032] The present invention also provides a method for separating impurities from bird's nests applied to the above-mentioned equipment, the specific steps of which are as follows: S1. Place the bird's nest to be processed into the base cylinder 100 and pour in low-temperature pure water. The water level should completely submerge the bird's nest and be slightly higher than the bottom of the filter 400.

[0033] S2. Set the initial rotation speed of the turbulence propeller 200 according to the grade of the bird's nest (such as whole bird's nest or bird's nest strips), and set the optimal rotation speed ratio between the filter 400 and the turbulence propeller 200 through the speed control component 700. For example, when processing top-grade whole bird's nest, a low-speed turbulence propeller 200 is used with a high-speed filter 400; when processing bird's nest strips with a high impurity content, a higher-speed turbulence propeller 200 can be used.

[0034] S3. Start the equipment. The external motor drives the turbulence propeller 200 and the filter 400 to rotate synchronously in opposite directions at a set speed ratio. At the same time, the microporous aeration disc 300 is started to generate microbubbles.

[0035] S4. During equipment operation, the rotating water flow pushes the bird's nest towards the side wall of the base cylinder 100, while light impurities such as feathers float to the surface under the influence of air bubbles. These floating impurities are intercepted by the counter-rotating wave plate section 420 and collected in the filter frame 410 under its curved guiding action.

[0036] S5. After the impurity removal process is completed, stop the machine. The operator can first remove the filter 400 to clean the impurities, and then take the cleaned bird's nest out of the base cylinder 100 to complete the entire impurity removal process.

[0037] The equipment and method for separating impurities in bird's nest provided in this invention have at least the following outstanding substantive features and significant advancements compared to the prior art: 1. This invention combines "active capture" and "passive floating": It utilizes rotating water flow to push lightweight impurities towards the central area, while simultaneously using a counter-rotating filter to continuously "sweep" the water surface. This dynamic interception mechanism ensures that impurities are guided into the filter frame as soon as they come into contact with the corrugated plate, completely solving the problem of impurity accumulation caused by the "stagnant zone" that easily forms in a rotating flow field when using a static filter.

[0038] 2. Excellent flexible processing capability: This invention avoids direct cutting of bird's nest strands through the large-area propulsion effect of the anchor-type turbulence propeller; at the same time, the microbubbles generated by the microporous aeration disc rise slowly and have a gentle impact force, which can penetrate deep into the folds of the bird's nest to remove impurities. This synergistic effect of water and air forces significantly reduces the breakage rate when processing top-grade white bird's nests, far superior to traditional mechanical stirring equipment.

[0039] 3. Intelligent Operation and Parameter Decoupling: Through a speed control component driven by a stepper motor, this invention achieves stepless adjustment of the speed of the turbulence propeller and the filter. For example, when processing low-grade bird's nest strips, a high-speed turbulence propeller can be set to enhance the peeling force, while a low-speed filter prevents impurities from escaping; when processing high-grade bird's nest pieces, a low-speed turbulence propeller can be set in conjunction with a high-speed filter, which both protects the shape of the bird's nest and ensures the timely collection of impurities.

[0040] 4. Humanized structural design: The filter adopts a plug-in detachable structure, combined with the design of the guide slope and the end flow channel, which not only facilitates the cleaning of impurities, but also optimizes the water flow field, prevents impurities from getting stuck at the connection, and improves the continuous operation capability and hygiene standards of the equipment.

[0041] In summary, through innovative mechanical structure design, this invention successfully achieves "high efficiency, low loss, and controllability" in the bird's nest impurity removal process, greatly improving the automation level and product yield of bird's nest deep processing.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention 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 the present invention.
