Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and more specifically, to a device and method for vortex separation of live and dead bait snails in the culture of broad-bodied golden thread leeches. Background Technology

[0002] The broad-bodied golden thread leech is a traditional Chinese medicine specified in the Chinese Pharmacopoeia. It has extremely high medicinal value. After processing, its dried form can effectively treat diseases such as hypertension, hyperlipidemia, stroke, and cerebral infarction, and has become one of the most sought-after Chinese medicinal materials. Currently, due to the high medicinal value and large market demand for the broad-bodied golden thread leech, relying solely on catching wild individuals can no longer meet the growing demand. There is an urgent need to carry out research on artificial breeding technology. Therefore, the broad-bodied golden thread leech has become an important new species in aquaculture. This type of leech does not suck the blood of vertebrates, but mainly feeds on the body fluids of mollusks such as snails, clams, and mussels, and is figuratively called "golden leech in water".

[0003] In existing technologies, the broad-bodied golden-line leech feeds only on the soft parts of forage snails, omitting the foot near the operculum. This makes it difficult to separate the snail remains from the live snails in a timely and efficient manner, leading to prolonged accumulation and decay, causing water pollution. Furthermore, it disperses tiny particles of low-grade fatty amines as aerosols in the farming area, producing an unpleasant odor. These low-grade fatty amines are harmful to broad-bodied golden-line leech farming. Due to the broad-bodied golden-line leech's feeding habits and unique feeding method, it further complicates disease control by making medication difficult; once infected, the snails ultimately die, and they also become active sources of infection. Therefore, based on the strategy of shifting the disease control focus forward, timely and efficient separation of live and dead forage snails, water purification, and enhancing the leech's own disease resistance become effective ways to control diseases.

[0004] Currently, the grassroots aquaculture industry, traditionally a labor-intensive industry, is gradually transforming into a technology-intensive one. Developing a cyclone separation device for live bait snails and debris snails, and promptly removing debris snails, can reduce the incidence of broad-bodied golden leeches, increase aquaculture efficiency, reduce the burden on workers, and improve productivity. Summary of the Invention

[0005] To address this issue, the present invention provides a cyclone separation device and method for live and dead bait snails in the cultivation of broad-bodied golden thread leeches, in order to solve the technical problem in the prior art where it is difficult to separate live bait snails and dead snails in a timely and efficient manner during the cultivation process, resulting in the long-term accumulation, decay and deterioration of the dead snails, which pollutes the cultivation environment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A cyclone separation device for live and dead bait snails in the cultivation of broad-bodied golden thread leeches includes: The pump suction conduction structure centrally collects the snails to be sorted; The vibrating sieve assembly groups the snails to be sorted according to their specifications based on the size of the aperture of the vibrating sieve disc; The self-falling conduction structure is connected and assembled with the pump suction conduction structure at the input end, and the self-falling conduction structure receives the snails and debris to be sorted and automatically transports and adaptively drains them. The wind-cyclone sorting structure includes a variable frequency fan assembly and a self-sorting inclined cavity tube positioned in a specific location; the self-sorting inclined cavity tube extends obliquely, and the top middle position of the obliquely extending self-sorting inclined cavity tube is connected to the output end of the self-falling conduction structure; the wind power output end of the variable frequency fan assembly is connected to the lower end of the self-sorting inclined cavity tube. The screw body storage structure is provided with a residual screw collection pipe and a live screw collection pipe; the residual screw collection pipe and the live screw collection pipe are respectively connected and assembled to the bottom side of the self-sorting inclined cavity pipe, and the residual screw collection pipe is located on the side of the live screw collection pipe away from the variable frequency fan assembly.

[0007] Based on the above technical solution, the present invention is further described as follows: As a further aspect of the present invention The pump suction conduction structure includes a flexible conveying pipe and a driving water pump suction head; The self-falling conduction structure includes a spiral self-falling inclined tube; The spiral body is inclined and extends obliquely as a whole, and the starting end of the spiral body is connected to the suction head of the driving water pump via a flexible conveying pipe. A water filter screen is provided on the side near the end of the spiral body inclined tube, and the lower end of the spiral body inclined tube is connected to the top middle part of the self-sorting inclined tube.

[0008] As a further aspect of the present invention The spiral body has several sets of adaptive balls and / or several sets of elastic protrusions with predetermined elasticity embedded in its bottom inner wall, and the adaptive balls and / or the elastic protrusions are all located on the upper side of the water filter screen.

[0009] As a further aspect of the present invention The self-selecting inclined cavity tube is provided with a gathering direct blowing section and a sealing and guiding section respectively on its lower end and upper end in the direction of extension. The inner cavity channel of the gathering direct blowing section is designed with a reduced diameter based on the overall inner cavity channel of the self-selecting inclined cavity tube, and the gathering direct blowing section is offset to one side of the spiral body self-falling inclined tube. The wind power output end of the variable frequency fan assembly is connected to the inlet end of the gathering direct blowing section. The live and residual snails falling into the self-sorting inclined cavity through the spiral falling pipe are simultaneously subjected to the wind force output from the variable frequency fan assembly and their own gravity. Due to the mass difference between the live and residual snails, the wind force output from the variable frequency fan assembly can effectively separate the live and residual snails in the upward direction. As the wind force flows along the self-sorting inclined cavity, the wind pressure gradually decreases, and the live and residual snails complete their descent under their own weight, corresponding to the live snail collection pipe and the residual snail collection pipe, respectively.

[0010] As a further aspect of the present invention The sealing and guiding air section is configured as an arc-shaped sealing plate. The air inlet side of the arc-shaped sealing and guiding air section is configured to correspond to the direct blowing direction of the gathering and direct blowing section, and the air outlet side of the arc-shaped sealing and guiding air section is configured to correspond to the inlet end of the residual screw collection and discharge pipe.

[0012] As a further aspect of the present invention The residual screw limiting part is also provided with an arc-shaped air guiding part on the side opposite to the residual screw collection and discharge pipe. The air guiding part is located on the upper side of the corresponding position of the screw body self-falling inclined pipe, so as to form an airflow to assist the residual screw to float inside the self-sorting inclined cavity pipe corresponding to the outlet area of ​​the screw body self-falling inclined pipe.

[0013] The self-selecting inclined cavity tube is also fixedly connected to the inlet end of the live screw receiving and discharging tube with a live screw limiting part, which is located on the side of the live screw receiving and discharging tube near the gathering and blowing part.

[0014] As a further aspect of the present invention The vibrating screen assembly includes a grading vibrating screen plate, a collection hopper, and channel valves; The grading vibrating screen includes several sets of vibrating screens, which are arranged obliquely from top to bottom between the drive pump suction head of the pump suction conduction structure and the inlet end of the flexible conveying pipe. Each set of vibrating screens is equipped with a variable frequency vibrating screen drive structure. The collecting hopper and the channel valve are provided in several groups. The inlet ends of the several groups of collecting hoppers are respectively connected to the downward-sloping ends of the several groups of vibrating screens. The outlet ends of the several groups of collecting hoppers are respectively connected to the flexible conveying pipe. The several groups of channel valves are respectively installed at the outlet ends of the several groups of collecting hoppers. The variable frequency fan assembly is connected to the control output terminal of the electronic control module via a circuit, and the control input terminal of the electronic control module is connected to several sets of channel valves via a circuit.

[0015] As a further aspect of the present invention, it also includes: The pre-removal component specifically includes a microporous jet structure, an electro-filter grid structure, and a biomimetic removal structure; The micro-orifice jet structure includes several controllable water pressure array pipes, and the ends of the array pipes are respectively equipped with micro-orifice nozzles facing the outer side of the electrical filter grid structure. The electrical filter grid structure includes a forward filter grid assembly and two sets of lateral filter grid assemblies that are respectively and sequentially arranged on both sides of the forward filter grid assembly, and the enclosure area formed by the electrical filter grid structure is correspondingly arranged with the pump suction head of the pump suction conduction structure. The forward filter assembly and the lateral filter assembly have the same structure, both including a live screw blocking part, an electric field filter part and a top shielding part that are fixedly connected from bottom to top. The live snail blocking part is configured as a cylindrical structure located at the bottom. When the micro-orifice jet structure releases a specific pressure water flow, the live snail blocking part plays a role in displacing and blocking the self-displaced live snails and smaller live snails that are blown up. The electric field filter grid part is configured as a vertical channel filter grid structure located in the middle, so that the blown-up residual snails can pass through the channel of the electric field filter grid part and reach the enclosure area of ​​the electric filter grid structure. The electric field filter grid part is connected to a deflecting electric field through a circuit. The top shield is arranged laterally above the electric field filter to block excessively blown-up residual screws; The biomimetic expulsion structure is provided in several groups, and the several groups of biomimetic expulsion structures are distributed and fixed to the electrical filter grid structure, and the biomimetic expulsion structure outputs the snail's natural enemy biomimetic vibration wave.

[0016] A method for separating live and dead snails from feed snails in the cultivation of Hirudo macrocarpa using the aforementioned cyclone separation device includes the following steps: S1: Obtain the snails to be sorted, and perform size sorting, automatic conveying, and adaptive drainage processes on the obtained snails, specifically including: The pump suction head in the pump-suction transmission structure concentrates the snails to be sorted in the breeding area. The snails, both live and dead, are then effectively sorted into different sizes by a variable frequency vibrating screen component at different specific vibration frequencies. The grouped snails are then further placed into different collection troughs and transported to a flexible conveying pipe through a channel valve. From there, they are transported to the snail body self-falling inclined pipe in the self-falling transmission structure. As the live and dead snails fall automatically within the self-falling inclined pipe, several sets of adaptive ball bearings and / or several sets of spring-loaded convex ridges assist in the self-turning effect of the falling snails and dead, thereby enhancing the drainage of water from inside the snail shells. This increases the quality difference between live and dead snails and improves the sorting efficiency of the subsequent wind resistance sorting process. Finally, the water is automatically drained to the water collection and circulation structure through a filter screen, completing the automatic drainage return circulation. S2: The cyclone sorting process is completed based on the mass difference between live and dead snails, specifically including: The variable frequency fan assembly of the cyclone sorting structure outputs wind force based on the specific specifications of the live and residual snails. At this time, the live and residual snails falling into the self-sorting inclined tube through the self-falling inclined tube can be simultaneously subjected to the wind force output by the variable frequency fan assembly and their own gravity. Due to the mass difference between the live and residual snails, the wind force output by the variable frequency fan assembly separates the live and residual snails in the upward direction. As the wind force flows along the self-sorting inclined tube, the wind pressure gradually decreases. With the guidance of the sealing and adjusting air guides, the live and residual snails fall to their respective positions under their own weight, thus completing the cyclone sorting process. S3: Further automatic classification and storage of live and dead snails after the cyclone sorting process, specifically including: The snail remains that have completed the cyclone sorting process automatically fall into the snail remains collection pipe under gravity, while the live snails that have completed the cyclone sorting process automatically fall into the live snail collection pipe under gravity, and then further fall into the snail remains collection chamber and the live snail collection chamber respectively.

[0017] The present invention has the following beneficial effects: This device and method effectively extracts and groups snails of specific sizes through a pump-suction conduction structure. Simultaneously, it utilizes a self-falling conduction structure to achieve automatic snail descent, transport, and adaptive drainage, thus effectively ensuring the efficiency of subsequent cyclone sorting. Furthermore, a water collection and circulation structure can be used to automatically circulate drainage back to the self-falling conduction structure. In addition, the cyclone sorting structure effectively utilizes the mass difference between live and dead snails to complete the cyclone sorting process. A snail collection and storage structure can automatically classify and receive live and dead snails from the cyclone sorting structure, significantly enhancing the efficiency of separating live and dead snails.

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The terms "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0028] Example 1 like Figures 1 to 3 As shown in the figure, this invention provides a cyclone separation device for live and dead snails in the cultivation of broad-bodied golden leeches. The device includes a pump-suction transmission structure 1, a free-fall transmission structure 2, a water collection and circulation structure 3, a cyclone separation structure 4, and a snail collection and storage structure 5. The pump-suction transmission structure 1 effectively extracts snails of specific sizes. Simultaneously, the free-fall transmission structure 2 enables automatic falling, conveying, and adaptive drainage of the snails, thus effectively ensuring the efficiency of subsequent cyclone separation. Furthermore, the water collection and circulation structure 3 corresponds to the free-fall transmission structure 2 to achieve automatic drainage recirculation. In addition, the cyclone separation structure 4 effectively utilizes the quality difference between live and dead snails to complete the cyclone separation process. The snail collection and storage structure 5 automatically classifies and receives live and dead snails from the cyclone separation structure 4, thereby significantly enhancing the efficiency of live and dead snail separation and improving its practicality. The specific settings are as follows: Please refer to Figure 1The pump suction conduction structure 1 includes a flexible conveying pipe 11 and a driving water pump suction head 12, and the self-falling conduction structure 2 includes a spiral self-falling inclined pipe 21; wherein, the spiral self-falling inclined pipe 21 extends obliquely as a whole, and the starting end of the spiral self-falling inclined pipe 21 on the upper side is connected and assembled between the flexible conveying pipe 11 and the driving water pump suction head 12, so as to concentrate the suction of live and residual snails to be sorted by the driving water pump suction head 12 and transport them to the spiral self-falling inclined pipe 21 through the flexible conveying pipe 11.

[0029] Please refer to Figure 1 and Figure 2 The spiral-shaped inclined tube 21 has a water-filtering screen 23 on its side near the bottom end. The spiral-shaped inclined tube 21 has several sets of adaptive ball bearings 22 and / or several sets of elastic protrusions 24 fixedly mounted on its bottom inner wall. These adaptive ball bearings 22 and / or elastic protrusions 24 are located on the upper side of the water-filtering screen 23. This allows for the automatic falling and conveying of live and dead snails via the spiral-shaped inclined tube 21. Furthermore, the adaptive ball bearings 22 and / or elastic protrusions 24 effectively assist the falling snails in enhancing their self-turning effect, making it easier to drain water from the shells of the dead snails. This increases the quality difference between live and dead snails, effectively ensuring the sorting efficiency during subsequent cyclone sorting processes. Additionally, the water-filtering screen 23 automatically drains water, improving the overall functionality and practicality.

[0030] Please continue to refer to this. Figure 1 The water collection and circulation structure 3 includes a water collection tank 31, a water guide inclined pipe 32, and a pump return pipe 33. The inlet end of the water collection tank 31 is connected to the outlet end of the filter screen 23 via the water guide inclined pipe 32, so that the water automatically discharged by the filter screen 23 can be further guided to the water collection tank 31. The water collection tank 31 is connected to the external aquaculture area via the pump return pipe 33, so as to cooperate with the pump suction conduction structure 1 and the self-falling conduction structure 2 to effectively complete the automatic drainage return circulation, further improving the functionality and practicality.

[0031] Please refer to Figure 1 and Figure 3The cyclone sorting structure 4 includes a variable frequency fan assembly 41, a self-sorting inclined cavity tube 42, a gathering and direct blowing section 43, a sealing and guiding section 44, a residual screw limiting section 45, a live screw limiting section 46, and a guiding section 47; wherein, the variable frequency fan assembly 41 and the self-sorting inclined cavity tube 42 are respectively positioned and connected, and the wind power output end of the variable frequency fan assembly 41 is connected to the self-sorting inclined cavity tube 42; specifically, the self-sorting inclined cavity tube 42 extends obliquely at a 45° angle, and the top middle position of the obliquely extending self-sorting inclined cavity tube 42 is connected to the lower end of the screw body self-falling inclined tube 21. The self-sorting inclined cavity tube 42 is provided with a gathering and direct blowing section 43 and a sealing and guiding section 44 corresponding to its lower and upper ends in the direction of extension, respectively; The inner cavity channel of the gathering direct blowing section 43 is designed with a reduced diameter based on the overall inner cavity channel of the self-selecting inclined cavity tube 42, and the gathering direct blowing section 43 is offset to one side of the spiral body falling inclined tube 21. The wind power output end of the variable frequency fan assembly 41 is connected to the inlet end of the gathering direct blowing section 43. This is to enable the live and dead snails falling from the spiral body falling into the self-selecting inclined cavity tube 42 to be simultaneously subjected to the wind power output from the variable frequency fan assembly 41 and their own gravity. In this way, due to the mass difference between the live and dead snails, the wind power output from the variable frequency fan assembly 41 can effectively separate the live and dead snails in the upward direction. As the wind power flows along the self-selecting inclined cavity tube 42, the wind pressure gradually decreases, and the live and dead snails complete their fall by their own weight at specific positions.

[0032] The snail body collection and storage structure 5 includes a residual snail collection and discharge pipe 51, a residual snail storage cavity 52, a live snail collection and discharge pipe 53, and a live snail storage cavity 54. The residual snail collection and discharge pipe 51 and the live snail collection and discharge pipe 53 are both inclined extensions. The upper end of the residual snail collection and discharge pipe 51 is connected to the bottom side of the self-sorting inclined cavity pipe 42 near the sealing air guide part 44, and the lower end of the residual snail collection and discharge pipe 51 is connected to the residual snail storage cavity 52. ​​The upper end of the live snail collection and discharge pipe 53 is connected to the bottom side of the self-sorting inclined cavity pipe 42 near the gathering direct blowing part 43, and the lower end of the live snail collection and discharge pipe 53 is connected to the live snail storage cavity 54. This structure serves as the basis for the sorting and storage function of live and residual snails.

[0033] More specifically, the sealing and guiding air section 44 is configured as an arc-shaped sealing plate. The air inlet side of the arc-shaped sealing and guiding air section 44 is arranged corresponding to the direct blowing direction of the gathering and direct blowing section 43, and the air outlet side of the arc-shaped sealing and guiding air section 44 is arranged corresponding to the inlet end of the residual screw collection and discharge pipe 51, so that the residual screw blown to the sealing and guiding air section 44 falls to the residual screw collection and discharge pipe 51 more efficiently.

[0034] The self-selection inclined cavity tube 42 is also fixedly connected to the inlet end of the residual screw collection and discharge tube 51 with a residual screw limiting part 45. The residual screw limiting part 45 is located on the side of the residual screw collection and discharge tube 51 away from the sealing and guiding air part 44, so as to significantly improve the residual screw collection rate through the residual screw limiting part 45.

[0035] The residual screw limiting part 45 is also provided with an arc-shaped air guiding part 47 on the side facing away from the residual screw collection and discharge pipe 51. The air guiding part 47 is located on the upper side of the corresponding position of the screw body self-falling inclined pipe 21. It is used to form an airflow that assists the residual screw to float inside the self-sorting inclined cavity pipe 42 corresponding to the outlet area of ​​the screw body self-falling inclined pipe 21, so that the residual screw can reach the residual screw collection and discharge pipe 51 more stably, and avoid the insufficient running force of the residual screw caused by the gradual decrease of wind pressure along the self-sorting inclined cavity pipe 42 due to the wind force.

[0036] The self-selecting inclined cavity tube 42 is also fixedly connected to the inlet end of the live snail collection and discharge tube 53 with a live snail limiting part 46. The live snail limiting part 46 is located on the side of the live snail collection and discharge tube 53 near the gathering and blowing part 43. It is used to significantly improve the live snail collection rate through the live snail limiting part 46, and to help form the offset gathering and blowing part 43 with the help of the live snail limiting part 46, thereby improving the overall functionality and practicality.

[0037] As a preferred embodiment, please refer to Figure 4The aforementioned bait snail live and residual cyclone sorting device further includes a vibrating screen assembly 9. Specifically, the vibrating screen assembly 9 includes a grading vibrating screen disc 91, a variable frequency vibrating screen drive structure 92, a collection hopper 93, and a channel valve 94. The grading vibrating screen disc 91 includes several sets of vibrating screen discs, which are arranged obliquely from top to bottom between the pump suction head 12 of the pump suction conduction structure 1 and the inlet end of the self-falling conduction structure 2. Each set of vibrating screen discs is equipped with a variable frequency vibrating screen drive structure 92, which enables the several sets of vibrating screen discs to effectively sort snails of different specifications at different specific vibration frequencies. The collection hopper 93 and the... Each channel valve 94 is provided with several sets. The inlet ends of the several sets of collecting troughs 93 correspond to several sets of vibrating screens and are connected to the downward-sloping ends of the several sets of vibrating screens. The outlet ends of the several sets of collecting troughs 93 are connected to the flexible conveying pipe 11. The several sets of channel valves 94 are respectively installed at the outlet ends of the several sets of collecting troughs 93. First, the different specifications of screws after grouping can fall into different collecting troughs 93 respectively. Then, the screws of different specifications are transported to the flexible conveying pipe 11 by the channel valves 94, which makes it easier for screws of specific specifications to be concentrated and completed in the subsequent sorting process.

[0038] More preferably, the variable frequency fan assembly 41 is configured as an electronically controlled variable frequency mechanism, and the variable frequency fan assembly 41 is connected to the control output end of an electronically controlled module via a circuit. The control input end of the electronically controlled module is connected to several sets of channel valves 94 via a circuit to realize automated control of the opening and closing state of the channel valves 94, and to automatically adjust the kinetic energy output frequency of the variable frequency fan assembly 41 according to the specific specification screw body output by the channel valve 94, thereby improving the adaptability to different specification screw bodies and significantly improving the overall sorting effect.

[0039] This invention also provides a method for separating live and dead snails using the aforementioned vortex sorting device for bait snails in the cultivation of broad-bodied golden thread leeches, specifically including the following steps: S1: Obtain the snails to be sorted, and perform sequential sorting, automatic conveying, and adaptive drainage processes on the obtained live and dead snails. The specific process is as follows: the pump head 12 in the pump suction transmission structure 1 concentrates the snails to be sorted in the breeding area, and the snails and their remains are collected and then effectively sorted into different sizes of snails by the variable frequency vibration screening component 9 at different specific vibration frequencies. The snails of different sizes after being grouped are further dropped into different collection troughs 93 and transported to the flexible conveying pipe 11 by the channel valve 94. Then, the flexible conveying pipe 11 is transported to the snail self-falling inclined pipe 21 in the self-falling transmission structure 2. When the snails and their remains are automatically falling and transported based on the snail self-falling inclined pipe 21, the snails and their remains are assisted by several sets of adaptive ball bearings 22 and / or several sets of elastic contact ridges 24 to enhance the self-turning effect of the falling snails and their remains, so as to enhance the discharge of water inside the snail shells, improve the quality difference between the snails and their remains, and improve the sorting efficiency of the subsequent cyclone sorting process. At the same time, the water is automatically drained to the water collection and circulation structure 3 by the water filter screen 23 to complete the automatic drainage return circulation. S2: The cyclone sorting process is completed based on the mass difference between live and dead snails; The specific process is as follows: The variable frequency fan assembly 41 of the cyclone sorting structure 4 outputs wind power according to the specific specifications of the live and residual snails. At this time, the live and residual snails falling into the self-sorting inclined cavity tube 42 through the self-falling inclined tube 21 can be simultaneously subjected to the wind power output from the variable frequency fan assembly 41 and their own gravity. Under the mass difference characteristics of the live and residual snails, the wind power output by the variable frequency fan assembly 41 separates the live snails and the residual snails in the upward direction. As the wind power flows along the self-sorting inclined cavity tube 42, the wind pressure gradually decreases. With the guidance of the sealing guide part 44 and the adjusting guide part 47, the live snails and the residual snails are respectively positioned to complete the self-weight fall at specific positions, thereby completing the cyclone sorting process. S3: Automatically classify and store live and dead snails that have completed the cyclone sorting process; The specific process is as follows: the snail residues that have completed the cyclone sorting process automatically fall to the snail residue collection pipe 51 under the action of gravity, while the live snails that have completed the cyclone sorting process automatically fall to the live snail collection pipe 53 under the action of gravity, and then further fall into the snail residue collection chamber 52 and the live snail collection chamber 54 respectively.

[0040] Example 2 In Example 2, the same symbols are used for the same structures as in Example 1, and the same descriptions are omitted. Example 2 is an improvement on Example 1. Please refer to [link / reference needed]. Figure 5 and Figure 6 The aforementioned cyclone separation device for live and dead bait snails in the cultivation of broad-bodied golden thread leeches also includes a pre-dispersal component.

[0041] Specifically, please refer to Figure 5The micro-orifice jet structure 6 includes a pressurization main pipe 61, array branch pipes 62, micro-orifice nozzles 63, pressure control valves 64, and positioning bends 65. The pressurization main pipe 61 serves as the main water supply pipe, responsible for delivering high-pressure water. A pressure control valve 64 is installed on it to regulate the water pressure and flow rate, ensuring that the water flow can flexibly meet the separation requirements of screws of different specifications. Several array branch pipes 62 are provided, and these branch pipes are connected to the end of the pressurization main pipe 61 via the positioning bends 65. The positioning bend 65 is configured to guide and stabilize the array branch pipes 62, while the array branch pipes 62 can effectively ensure uniform water flow distribution to fully cover the target area. Each end of several array branch pipes 62 is equipped with a micro-orifice nozzle 63, which sprays water at a specific pressure to initially separate the pumped snails. This allows the lighter snail debris to be blown up while preventing the heavier live snails from being blown away, keeping the live snails at the bottom, thus completing the initial separation of live and debris snails.

[0042] More specifically, the orifice diameter of the micro-orifice nozzle 63 is set to a range of 0.5 mm to 1.5 mm, and the spray angle of the micro-orifice nozzle 63 is set to a range of 30° to 60°. This allows for flexible adjustment of the specific spray position towards the outer side of the electrical filter structure as needed, thereby better adapting to snails at different growth stages.

[0043] Please refer to Figure 5 and Figure 6 The electrical filter structure 7 is configured as a C-shaped structure. The C-shaped electrical filter structure 7 includes a forward filter assembly 71 and two sets of lateral filter assemblies 72 respectively connected to each other on both sides of the forward filter assembly 71. The enclosure area formed by the C-shaped electrical filter structure 7 is correspondingly arranged between the pump suction head 12 of the pump suction conduction structure 1 and the forward filter assembly 71 is located in the pump suction direction of the pump suction head 12.

[0044] Specifically, the forward filter assembly 71 and the lateral filter assembly 72 have the same structure, both including a live screw blocking part 73, an electric field filter part 74, and a top shielding part 75 that are fixedly connected from bottom to top. The live screw blocking part 73 is configured as a cylindrical structure at the bottom. When the micro-orifice jet structure 6 releases water at a specific pressure, the live screw blocking part 73 can effectively block the displacement of live screws and smaller live screws that are blown up. The electric field filter part 74 is configured as a vertical channel filter structure in the middle. The electric field filter part 74 is connected to a driving electric field with a driving electric field strength of 5~10V / cm through an electrical circuit. This is used to further drive away live screws through the electric field, while allowing blown-up residual screws to pass through the channel of the electric field filter part 74 and reach the enclosure area of ​​the electric filter structure 7.

[0045] The top shielding part 75 is laterally positioned above the electric field filter section 74 to block excessively blown residual screws to a certain extent, allowing the residual screws to pass through the channel of the electric field filter section 74 more efficiently.

[0046] More specifically, the top shielding portion 75 may adopt, but is not limited to, a filter grid structure, and the filter grid channel width of the top shielding portion 75 is smaller than the channel width of the electric field filter grid portion 74.

[0047] Please continue to refer to this. Figure 5 The top shielding part 75 has a top mounting plate 76 fixedly connected to its inner side for distributively installing the bionic repelling structure 8. Specifically, the bionic repelling structure 8 is provided in several groups, and the several groups of bionic repelling structures 8 are distributedly fixed to the top mounting plate 76. The bionic repelling structure 8 is configured as a vibration generator with a vibrating plate. The vibration generator outputs vibration waves with a frequency range of 50Hz~100Hz to simulate the vibration pulse signal of snail predators and output bionic vibration waves of snail predators to further assist in repelling live snails in various directions, so as to enhance the repelling effect on live snails.

[0048] The installation spacing of several sets of the biomimetic dispersing structures 8 is 10cm~15cm, so as to ensure that the vibration wave forms a uniform coverage in the target area, further improving the separation effect of live snails and snail remains.

[0049] The working process of the pre-removal component is as follows: First, the micro-orifice jet structure 6 is activated, and the pressure control valve 64 adjusts the water pressure and flow rate. The water flows through the pressurization main pipe 61 into the positioning bend pipe 65, and then through the array distribution pipe 62 to each micro-orifice nozzle 63. The micro-orifice nozzle 63 sprays water at a specific pressure to blow up the lighter residual snails, while the heavier live snails remain at the bottom due to their greater weight, thus achieving the initial separation of live and residual snails. Subsequently, the live screw blocking part 73 blocks smaller live screws that have shifted on their own or been blown up, preventing them from entering the sorting channel; the electric field filter part 74 further drives away the live screws by dispersing the electric field, while allowing the blown-up residual screws to pass through; the top shielding part 75 plays a certain role in blocking the excessively blown-up residual screws, so that the residual screws can pass through the channel of the electric field filter part 74 more efficiently and reach the suction area of ​​the drive pump suction head 12. Finally, the biomimetic expulsion structure 8 outputs biomimetic vibration waves that drive away live snails from all directions. Throughout the process, the components work together to significantly improve the separation effect between live and dead snails underwater.

[0050] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

The electrical filter grid structure includes a forward filter grid assembly and two sets of lateral filter grid assemblies that are respectively and sequentially arranged on both sides of the forward filter grid assembly, and the enclosure area formed by the electrical filter grid structure is correspondingly arranged with the pump suction head of the pump suction conduction structure. The forward filter assembly and the lateral filter assembly have the same structure, both including a live screw blocking part, an electric field filter part and a top shielding part that are fixedly connected from bottom to top. The live snail blocking part is configured as a cylindrical structure located at the bottom. When the micro-orifice jet structure releases a specific pressure water flow, the live snail blocking part plays a role in displacing and blocking the self-displaced live snails and smaller live snails that are blown up.

9. A method for separating live and residual bait snails using a vortex separation device in the cultivation of *Hirudo macrocarpa* according to any one of claims 1-8, characterized in that... Includes the following steps: The process involves acquiring snails to be sorted, sorting them by size, automatic conveying, and adaptive drainage. The cyclone sorting process is completed based on the quality differences between live and dead snails; The system automatically classifies and stores live and dead snails that have completed the cyclone sorting process.

10. The method for wind-swirling separation of live and dead bait snails in the culture of broad-bodied golden leeches according to claim 9, characterized in that, The process of acquiring snails to be sorted, sorting them by size, automatically conveying them, and adaptively draining them specifically includes: The pump suction head in the pump suction transmission structure concentrates the snails to be sorted in the breeding area. The snails and their remains are then effectively sorted into different sizes by a variable frequency vibrating screen component at different specific vibration frequencies. The snails of different sizes are then further divided into different collection troughs and transported to a flexible conveying pipe through a channel valve. The flexible conveying pipe then transports the snails to the snail self-falling inclined pipe in the self-falling transmission structure. When the snails and their remains are automatically transported in the snail self-falling inclined pipe, several sets of adaptive ball bearings and / or several sets of elastic contact ridges assist the snails and their remains in falling, enhancing the self-turning effect and accelerating the discharge of water from the snail shells. This improves the quality difference between the snails and their remains and the sorting efficiency of the subsequent cyclone sorting process. Finally, the water is automatically drained to the water collection and circulation structure through a filter screen, completing the automatic drainage return circulation. The cyclone sorting process is based on the quality difference between live and dead snails, specifically including: The variable frequency fan assembly of the cyclone sorting structure outputs wind force based on the specific specifications of the live and residual snails. At this time, the live and residual snails falling into the self-sorting inclined cavity through the self-falling inclined tube can be simultaneously subjected to the wind force output by the variable frequency fan assembly and their own gravity. Due to the mass difference between the live and residual snails, the wind force output by the variable frequency fan assembly separates the live snails and the residual snails in an upward direction. As the wind force flows along the self-sorting inclined cavity, the wind pressure gradually decreases. With the guidance of the sealing and adjusting air guides, the live and residual snails fall to their respective positions under their own weight, thus completing the cyclone sorting process. The system further automatically classifies and stores live and damaged snails after the cyclone sorting process, specifically including: The snail remains that have completed the cyclone sorting process automatically fall into the snail remains collection pipe under gravity, while the live snails that have completed the cyclone sorting process automatically fall into the live snail collection pipe under gravity, and then further fall into the snail remains collection chamber and the live snail collection chamber respectively.
