Description

Technical Field

[0001] This invention relates to the field of material crushing technology, specifically to an apparatus and method for the three-dimensional cultivation and purification of microalgae wastewater coupled with the preparation of aquatic feed. Background Technology

[0002] In large-scale wastewater treatment processes, sewage (especially domestic sewage, aquaculture wastewater, and agricultural wastewater) often contains large amounts of nutrients such as nitrogen (e.g., ammonia nitrogen, nitrate) and phosphorus (e.g., phosphate). Direct discharge of these substances can lead to eutrophication of water bodies (e.g., cyanobacterial blooms in lakes, red tides in the sea). Therefore, a large quantity or a large diameter of microalgae hydrogel beads (made from sodium alginate and chitosan, with microalgae injected into the beads to obtain microalgae-containing hydrogel beads) is needed for active absorption and metabolism. This allows microalgae and heterotrophic microorganisms to form an "algae-bacteria symbiotic system," synergistically improving degradation efficiency. After wastewater treatment, the microalgae hydrogel beads remain in the wastewater treatment device. While purifying sewage, the microalgae hydrogel beads themselves accumulate a large amount of biomass (e.g., proteins, oils, carbohydrates) through photosynthesis. Therefore, aquatic feed preparation equipment is needed to further transform microalgae hydrogel beads, turning waste into treasure and promoting resource recycling. However, the existing coupled aquatic feed preparation process requires a crusher to break large or granular microalgae hydrogel bead raw materials into smaller particles to ensure the continuity of subsequent microalgae hydrogel bead processing. However, when crushing microalgae hydrogel bead raw materials, existing crushers add a large amount of raw materials to ensure that the crusher can work continuously for a long time without frequent stops for feeding. Moreover, all raw materials are discharged uniformly after reaching the preset crushing degree. This results in raw materials that have reached the appropriate particle size still being mixed with other large particles that still need to be crushed. As a result, these qualified raw materials continue to remain in the crushing chamber and are over-crushed, affecting the quality of raw materials and reducing the quality of aquatic feed preparation. Summary of the Invention

[0003] The purpose of this invention is to provide an apparatus and method for the three-dimensional cultivation and purification of microalgae wastewater coupled with the preparation of aquatic feed, so as to solve the above-mentioned deficiencies in the technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an apparatus and method for three-dimensional microalgae cultivation and wastewater purification coupled with aquatic feed preparation, comprising a crusher frame, coarse and fine crushing seats, and a crushing core disc column. An annular receiving tray for receiving materials is movably connected inside the crusher frame. A discharge port is provided on one side of the crusher frame. A dispersing assembly is provided between the crushing core disc column, the annular receiving tray, and the crusher frame for connection. The dispersing assembly includes a connecting cylinder installed at the bottom of the crushing core disc column and an abutting cone column installed inside the crusher frame. A slow-descent frame that cooperates with the abutting cone column is fixedly connected to the outside of the connecting cylinder, and the slow-descent frame is used to drive the crushing core disc column to move intermittently along the interior of the coarse and fine crushing seats. A granulation assembly is provided between the annular receiving tray and the connecting cylinder to rapidly rebound the intermittently moving crushing core disc column within the coarse and fine crushing seats. A shaking and distributing assembly for dispersing or classifying materials is provided between the crusher frame and the coarse and fine crushing seats. A clearing assembly for pushing materials is provided between the crusher frame and the annular receiving tray.

[0005] Preferably, the pelletizing assembly includes a push spring installed at the bottom of the connecting cylinder and inside the annular receiving plate, and a crushing and twisting disc fixedly connected to the top of the crushing core disc column. The crushing and twisting disc column is configured as an inclined pentagonal structure. A first servo motor is fixedly connected to the bottom of the crusher frame, and a rotating column is fixedly connected to the output end of the first servo motor. The top of the rotating column passes through the crusher frame, the annular receiving plate, the connecting cylinder, and the crushing core disc column from bottom to top and is movably sleeved inside the crushing and twisting disc column. The rotating column is used to drive the annular receiving plate and the crushing core disc column to rotate. An electric push rod is fixedly connected inside the crusher frame, and the electric push rod is used to control the movement of the contact cone column up and down along the top of the deceleration frame.

[0006] Preferably, the bottom end of the torsion-breaking disc column is fixedly connected to an annular protrusion, and the annular protrusion is sleeved on the outside of the rotating column. The outside of the rotating column is provided with a displacement groove for the annular protrusion to move up and down.

[0007] Preferably, the material distribution assembly includes a diversion plate installed between the coarse and fine crushing seat and the crusher frame, and a support rod fixedly connected to the top of the crushing disc column. The diversion plate and the coarse and fine crushing seat are used to alternate the material feeding method. The top of the diversion plate is provided with a diversion cavity communicating with the interior of the coarse and fine crushing seat. The top of the support rod is fixedly connected with a shift frame, and the shift frame moves up and down reciprocally along the diversion cavity.

[0008] Preferably, the diverter plate and the crusher frame are connected by an external gear ring, and a second servo motor is fixedly connected to the outside of the crusher frame. The output end of the second servo motor is fixedly connected to a gear that meshes with the external gear ring, and the gear is used to drive the diverter plate to rotate along the outside of the shift frame.

[0009] Preferably, the clearing assembly includes a stabilizing frame fixedly connected to the inside of the crusher frame and the discharge port, and a movable frame slidably connected to the outside of the stabilizing frame, with a certain distance between the movable frame and the stabilizing frame. Several meshing columns are fixedly connected to the side of the stabilizing frame near the movable frame. A third servo motor is installed inside the movable frame, and an annular toothed disc that cooperates with the meshing columns is installed at one end of the third servo motor. A pusher plate is installed on one side of the movable frame, and the pusher plate is configured with a willow leaf-shaped structure. A lifting assembly for connection is provided between the stabilizing frame and the annular toothed disc.

[0010] Preferably, the lifting assembly includes a first and a second auxiliary pin fixedly connected to one side of the stabilizer, and the first and second auxiliary pins are used to drive the annular toothed disc to move in multiple dimensions along one side of the stabilizer. The third servo motor is externally fixedly sleeved with a limit frame, and the inside of the moving frame is provided with a limit groove for the limit frame to move up and down. The limit frame and the push plate are connected by a guide seat.

[0011] The method for using a microalgae three-dimensional culture and purification wastewater coupled with aquatic feed preparation device includes the following steps:

[0012] S1. By placing the microalgae hydrogel raw material inside the shaking and distributing component, the shaking and distributing component disperses and evenly feeds the microalgae hydrogel raw material inside into the coarse and fine crushing seat. The coarse and fine crushing seat rotates under the rotation of the shaking and distributing component. At this time, the coarse and fine crushing seat and the crushing core disc are used to crush and prepare the microalgae hydrogel raw material.

[0013] S2. Secondly, under the action of the dispersion component, the crushing core disc rotates along the inside of the coarse and fine crushing seat. During the rotation, the crushing core disc moves slowly and intermittently downward along the inside of the coarse and fine crushing seat. Then, the gap between the coarse and fine crushing seat and the crushing core disc changes continuously. At this time, smaller microalgae hydrogel raw materials fall through the gap onto the surface of the annular receiving plate. The remaining microalgae hydrogel raw materials are still being crushed and prepared during the descent and fall onto the surface of the annular receiving plate.

[0014] S3. Next, the granulation component is used to move the crushing core column downward to a certain position and then push it back. Then the position of the microalgae hydrogel raw material inside the crushing core column and the coarse and fine crushing seat is adjusted, and the microalgae hydrogel raw material continues to be prepared inside the crushing core column and the coarse and fine crushing seat to ensure the quality of feed preparation.

[0015] S4. Subsequently, the microalgae hydrogel bead raw material after crushing and preparation is pushed into the discharge port by the clearing component to process the microalgae hydrogel bead raw material in the annular receiving tray, ensuring the continuity of microalgae hydrogel bead raw material preparation.

[0016] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0017] 1. This invention, through the arrangement of a crushing core column, coarse and fine crushing seats, a slow-descent frame, and an abutting cone column, enables the crushing core column to generate circumferential shearing and friction on the microalgae hydrogel raw material. The vertical adjustment can change the distance between the crushing core column and the coarse and fine crushing seat cavity arms, allowing the microalgae hydrogel raw material to be subjected to squeezing and kneading under different pressures and gaps. When the crushing core column is adjusted downwards, the gap widens, and the crushed particles are discharged from the coarse and fine crushing seats and the crushing core column within this gap, while the remaining microalgae hydrogel raw material continues to be crushed. Furthermore, when the crushing core column is reset upwards, the gap narrows, increasing the pressure applied to the microalgae hydrogel raw material, which more effectively crushes the initially crushed particles, increases the effective crushing time, improves crushing efficiency, and facilitates the utilization of the feed.

[0018] 2. The present invention, through the arrangement of the crushing core column, coarse and fine crushing seats, push-back spring and connecting cylinder, ensures that the forces exerted on microalgae hydrogel raw materials of different sizes and positions during the grinding process are different. Therefore, after the crushing core column moves down a certain position, it can quickly push back. The rapid push-back reset can disrupt the original distribution state of the particles, so that the particles have a more uniform chance to contact all parts of the crushing core column and coarse and fine crushing seats. Particles that were originally in a loose state or not fully acted upon can be remixed and squeezed during the push-back process, reducing the situation of local uncrushed or inconsistent crushing degree, and improving the uniformity of the overall microalgae hydrogel raw material crushing.

[0019] 3. The present invention forms a throat movement mode by setting up a torsion disc column, a core disc column, and coarse and fine crushing seats. The torsion disc column can improve the accumulation state of the microalgae hydrogel raw material, redistribute the gaps between particles, increase the fluidity of particles, and make the microalgae hydrogel raw material gradually shrink between the coarse and fine crushing seats and the core disc column. The microalgae hydrogel raw material is subjected to uniform force during the crushing process, which is conducive to obtaining a more uniform particle size distribution and improving product quality.

[0020] 4. By setting up the support rod, the crushing disc column, and the diversion chamber, this invention can redistribute the microalgae hydrogel raw material in the gap between the coarse and fine crushing seats and the crushing core disc column, increasing the fluidity of the particles and reducing the accumulation of microalgae hydrogel raw material inside. This makes the newly added microalgae hydrogel raw material and the unremoved microalgae hydrogel raw material loose, which is more conducive to the entry of new microalgae hydrogel raw material into the grinding area. It can effectively prevent the excessive accumulation and agglomeration of particles in local areas, avoid production interruptions and equipment failures caused by blockage, ensure the continuity and stability of the microalgae hydrogel raw material crushing and preparation process, and also help improve the purity of the feed.

[0021] 5. The present invention, through the arrangement of the diversion plate, external toothed ring, coarse and fine crushing seat, crushing core disc column and dispersion assembly, can achieve coordinated cooperation between the rotating coarse and fine crushing seat and the rotating and vertically moving crushing core disc column, so that the force on each part of the crushing core disc column and the coarse and fine crushing seat is more uniform, avoiding the same part from bearing excessive pressure and friction for a long time. The grinding cores in different areas participate in the grinding process alternately, making the wear more dispersed and extending the service life of the crushing core disc column and the coarse and fine crushing seat.

[0022] 6. This invention, through the arrangement of a pusher plate, a lifting assembly, a discharge port, and an annular receiving tray, allows the pusher plate to perform a looping motion inside the annular receiving tray and the discharge port. This enables the pusher plate to quickly push out the microalgae hydrogel material from the surface of the annular receiving tray. Furthermore, during the process of the pusher plate returning from the discharge port to the surface of the annular receiving tray, there is a movement distance between the pusher plate and the discharge port and the annular receiving tray. This prevents the annular receiving tray from contacting the microalgae hydrogel material on the surface of the annular receiving tray and the discharge port during the resetting process, thus avoiding the occurrence of the microalgae hydrogel material being pushed back. This improves the comprehensiveness and thoroughness of the collection of microalgae hydrogel material. Attached Figure Description

[0039] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] This invention provides, for example Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The apparatus and method for the three-dimensional cultivation and purification of microalgae wastewater coupled with the preparation of aquatic feed, as shown, includes a crusher frame 1, a coarse and fine crushing seat 13, and a crushing core disc column 14. An annular receiving tray 12 for receiving materials is movably connected inside the crusher frame 1. A discharge port 11 is provided on one side of the crusher frame 1. A dispersing assembly 2 is provided between the crushing core disc column 14, the annular receiving tray 12, and the crusher frame 1 for connection. The dispersing assembly 2 includes a connecting cylinder 21 installed at the bottom of the crushing core disc column 14 and an abutting cone column 23 installed inside the crusher frame 1. A decelerating frame 22 that cooperates with the abutting cone column 23 is fixedly connected to the outside of the connecting cylinder 21. The decelerating frame 22 is used to drive the crushing core disc column 14 to move intermittently along the interior of the coarse and fine crushing seat 13. A granulation assembly is provided between the annular receiving tray 12 and the connecting cylinder 21 to rapidly rebound the intermittently moving crushing core disc column 14 within the coarse and fine crushing seat 13.

[0041] The pelletizing assembly includes a push spring 25 installed at the bottom of the connecting cylinder 21 and inside the annular receiving plate 12, and a crushing disc column 28 fixedly connected to the top of the crushing core disc column 14. The crushing disc column 28 is configured as an inclined pentagonal structure. A first servo motor 26 is fixedly connected to the bottom of the crusher frame 1, and a rotating column 27 is fixedly connected to the output end of the first servo motor 26. The top of the rotating column 27 passes through the crusher frame 1, the annular receiving plate 12, the connecting cylinder 21, and the crushing core disc column 14 from bottom to top. The rotating column 27 is movably fitted inside the crushing and twisting disc column 28, and is used to drive the annular receiving disc 12 and the crushing core disc column 14 to rotate. An electric push rod 24 is fixedly connected inside the crusher frame 1, and the electric push rod 24 is used to control the contact cone column 23 to move up and down along the top of the slow-falling frame 22. An annular boss 29 is fixedly connected to the bottom end of the crushing and twisting disc column 28, and the annular boss 29 is fitted outside the rotating column 27. A displacement groove 201 is opened on the outside of the rotating column 27 for the annular boss 29 to move up and down.

[0042] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the crushing disc 28 is inside the coarse and fine crushing seat 13, and there is a distance between the crushing disc 28 and the coarse and fine crushing seat 13. The movement state between the crushing disc 28 and the crushing core disc 14 and the coarse and fine crushing seat 13 is set as the throat movement mode. In addition, there are two sets of the contact cone 23, the electric push rod 24 and the deceleration frame 22. The deceleration frame 22 is set as an inclined and meandering arc structure. The deceleration frame 22 is symmetrically arranged outside the connecting cylinder 21. The contact cone 23 and the deceleration frame 22 are in correspondence.

[0043] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, when a large amount of microalgae hydrogel raw material is coarsely prepared, the microalgae hydrogel raw material is placed inside the shaking and distributing component 3. The shaking and distributing component 3 then disperses the microalgae hydrogel raw material into the coarse and fine crushing seat 13. At this time, the first servo motor 26 rotates, driving the rotating column 27 to rotate along the inside of the crusher frame 1. The rotation of the rotating column 27 also drives the annular receiving plate 12 to rotate synchronously along the inside of the crusher frame 1. Simultaneously, the rotation of the rotating column 27 drives the displacement groove 201 to rotate synchronously. Moreover, during the rotation of the displacement groove 201, a gap is formed between its interior and the annular protrusion 29. The contact cone 23 is activated and rotates synchronously with the annular convex seat 29. This rotation of the annular convex seat 29, in turn, causes the crushing disc 28 and the crushing core disc 14 to rotate synchronously. As the crushing core disc 14 rotates, it generates pressure at different positions between the microalgae hydrogel material and the coarse and fine crushing seats 13, thus crushing and preparing the microalgae hydrogel material. Simultaneously, the electric push rod 24, according to a pre-set time, pushes or pulls the contact cone 23 downwards or upwards along the crusher frame 1. As the electric push rod 24 extends and retracts downwards, it moves the contact cone 23 along the crusher frame 1, thereby increasing the pressure on the microalgae hydrogel material. As the column 23 moves downward, it is offset from the deceleration frame 22, and the contact cone column 23 continues to move downward, forming contact with the top of the deceleration frame 22, which has already circled once inside the crusher frame 1. Subsequently, the deceleration frame 22 rotates along the bottom of the contact cone column 23 and slowly moves downward under the rotation of the connecting cylinder 21. During the downward movement of the connecting cylinder 21, its bottom moves deeper into the interior of the annular receiving plate 12. Then, the push spring 25 is squeezed between the connecting cylinder 21 and the annular receiving plate 12, thereby causing the crushing core disc column 14 to slowly move downward along the interior of the coarse and fine crushing seat 13. During the process, the crushing core disc 14 moves downward, causing the crushing torsion disc 28 to move downward simultaneously, so that the annular protrusion 29 moves downward along the inside of the displacement groove 201, thereby meeting the multi-directional rotation requirement of the crushing core disc 14. During this process, the crushing core disc 14 can both rotate and slowly move downward along the inside of the coarse and fine crushing seat 13. After it comes into contact with the cone 23 and the deceleration frame 22 and they are misaligned, the elasticity of the push spring 25 can give the top of the connecting cylinder 21 an upward thrust, which then pushes the connecting cylinder 21 upward quickly, ensuring that the crushing core disc 14 quickly resets within the coarse and fine crushing seat 13.

[0044] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a material distribution assembly 3 for dispersing or classifying materials is provided between the crusher frame 1 and the coarse and fine crushing seat 13. The material distribution assembly 3 includes a diversion plate 31 installed between the coarse and fine crushing seat 13 and the crusher frame 1, and a support rod 34 fixedly connected to the top of the crushing disc column 28. The diversion plate 31 and the coarse and fine crushing seat 13 are used to alternate the material feeding method. The top of the diversion plate 31 is provided with a diversion cavity 32 that communicates with the interior of the coarse and fine crushing seat 13. The top of the support rod 34 is fixedly connected to a shift frame 33, and the shift frame 33 moves up and down along the diversion cavity 32.

[0045] The diverter plate 31 and the crusher frame 1 are connected by an external gear ring 35. The crusher frame 1 is fixedly connected to a second servo motor 37. The output end of the second servo motor 37 is fixedly connected to a gear 36 that meshes with the external gear ring 35. The gear 36 is used to drive the diverter plate 31 to rotate along the outside of the shift frame 33.

[0046] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the coarse and fine crushing seat 13 and the diversion plate 31 have two usage methods when feeding microalgae hydrogel raw materials. First, when crushing and preparing microalgae hydrogel raw materials of the same specification, the microalgae hydrogel raw materials are placed inside the diversion plate 31, and the diversion plate 31 continuously feeds the microalgae hydrogel raw materials inside it into the coarse and fine crushing seat 13. Second, when crushing microalgae hydrogel raw materials of different specifications, some microalgae hydrogel raw materials are fed into the coarse and fine crushing seat 13, and then the other part is placed inside the diversion plate 31. The coarse and fine crushing seat 13 and the crushing core plate 14 pre-crush some of the microalgae hydrogel raw materials inside it. Then the diversion plate 31 gradually feeds the other part of the microalgae hydrogel raw materials into the coarse and fine crushing seat 13. This makes the processing of microalgae hydrogel raw materials of different specifications sequential, increases the amount of microalgae hydrogel raw materials processed per unit time, and improves production efficiency.

[0047] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, and according to the above steps, when the crushing disc 28 slowly moves downward along the interior of the coarse and fine crushing seat 13, the downward movement of the crushing disc 28 drives the support rod 34 to move downward synchronously along the interior of the coarse and fine crushing seat 13. Then, the movement of the support rod 34 drives the shifting frame 33 to move downward synchronously along the interior of the diversion cavity 32. The height difference between the top of the shifting frame 33 and the diversion plate 31 continuously decreases. At this time, the shifting frame 33 slides out of the interior of the diversion cavity 32, and there is a gap between the shifting frame 33 and the diversion plate 31. Furthermore, the microalgae hydrogel material on the surface of the diversion plate 31 slides down through the diversion cavity 32 into the interior of the coarse and fine crushing seat 13 for coarse and fine crushing. The interior of seat 13 is filled with microalgae hydrogel material. During this process, the second servo motor 37 drives the gear 36 to rotate. Then, the gear 36 meshes with the external gear ring 35 to drive the external gear ring 35 to rotate along the top of the crusher frame 1, which disperses the microalgae hydrogel material inside the diversion plate 31. At the same time, the rotation of the external gear ring 35 drives the diversion plate 31 and the coarse and fine crushing seat 13 to rotate synchronously, so that the coarse and fine crushing seat 13 and the crushing core disc column 14 are aligned to crush the microalgae hydrogel material at different positions inside, reducing excessive wear between the crushing core disc column 14 and the coarse and fine crushing seat 13 and extending the service life of the equipment.

[0048] refer to Figure 7 , Figure 8 and Figure 9 As shown, a clearing assembly 4 for pushing material is provided between the crusher frame 1 and the annular receiving plate 12. The clearing assembly 4 includes a stabilizing frame 41 fixedly connected to the inside of the crusher frame 1 and the discharge port 11, and a moving frame 43 slidably connected to the outside of the stabilizing frame 41. There is a certain distance between the moving frame 43 and the stabilizing frame 41. Several meshing pins 44 are fixedly connected to the side of the stabilizing frame 41 near the moving frame 43. A third servo motor 45 is installed inside the moving frame 43. An annular toothed disc 46 that cooperates with the meshing pins 44 is installed at one end of the third servo motor 45. A pusher plate 42 is installed on one side of the moving frame 43. The pusher plate 42 is designed with a willow leaf shape. A lifting assembly 5 for connection is provided between the stabilizing frame 41 and the annular toothed disc 46. The outer teeth of the annular toothed disc 46 mesh with the second auxiliary meshing pin 55, the several meshing pins 44 and the first auxiliary meshing pin 51.

[0049] refer to Figure 7 , Figure 8 and Figure 9As shown, the lifting assembly 5 includes a first attachment post 51 and a second attachment post 55 respectively fixedly connected to one side of the stabilizer 41. The first attachment post 51 and the second attachment post 55 are used to drive the ring toothed disk 46 to move in multiple dimensions along one side of the stabilizer 41. The third servo motor 45 is externally fixedly sleeved with a limit frame 53. The inside of the moving frame 43 is provided with a limit groove 52 for the limit frame 53 to move up and down. The limit frame 53 and the push plate 42 are connected by a guide seat 54.

[0050] refer to Figure 7 , Figure 8 and Figure 9As shown, when the annular receiving tray 12 collects the crushed microalgae hydrogel material on its surface, and the microalgae hydrogel material needs to be quickly discharged from the surface of the annular receiving tray 12 into the discharge port 11, the third servo motor 45 drives the annular toothed disc 46 to rotate synchronously. The annular toothed disc 46 then rotates and forms a meshing transmission with the first auxiliary meshing post 51 and several meshing posts 44. At this time, the annular toothed disc 46 moves horizontally along the outside of the first auxiliary meshing post 51 and several meshing posts 44. During this movement, the annular toothed disc 46 drives the moving frame 43 to move horizontally along one side of the stabilizing frame 41 and several meshing posts 44, causing the moving frame 43 to move synchronously, driving the limiting frame 53, the guide seat 54, and the pusher plate 42. During this process, the pusher plate... The movement 42 is used to push the microalgae hydrogel material on the surface of the annular receiving tray 12, causing the microalgae hydrogel material on the surface of the annular receiving tray 12 to move towards the inside of the discharge port 11. When the annular toothed disc 46 moves to the vicinity of the second meshing post 55, the annular toothed disc 46 and the second meshing post 55 are engaged, so the rotation of the annular toothed disc 46 moves along the outer circumference of the second meshing post 55. As the annular toothed disc 46 moves upward along one side of the stabilizing frame 41, the upward movement of the annular toothed disc 46 drives the third servo motor 45 and the limiting frame 53 to move upward synchronously along the inside of the limiting groove 52. Subsequently, the pusher plate 42 moves upward along one side of the moving frame 43 under the movement of the limiting frame 53, so that the pusher plate 42 and the inside of the discharge port 11 are engaged. There is a certain height. During this process, the horizontal movement of the pusher plate 42 changes to an upward movement. Through the continuous rotation of the annular toothed disc 46, it engages with the second auxiliary meshing post 55 and several meshing posts 44 to drive the moving frame 43 and the pusher plate 42 to move horizontally from right to left. Similarly, when the annular toothed disc 46 and the moving frame 43 move back to the vicinity of the first auxiliary meshing post 51, the annular toothed disc 46 moves along the outer circumference of the first auxiliary meshing post 51, causing the annular toothed disc 46 to move from top to bottom along one side of the stabilizing frame 41. As a result, the limiting frame 53 and the third servo motor 45 move downward along the inside of the limiting groove 52, and the pusher plate 42 re-contacts the surface of the annular receiving plate 12. This process is repeated, causing the pusher plate 42 to reciprocate along one side of the stabilizing frame 41 in a loop. The movement of the pusher plate 42 within the discharge port 11 allows it to maintain multiple movement states, changing from horizontal movement from left to right to upward movement, and then from horizontal movement from right to left to downward movement, repeating this process. Firstly, during the crushing of microalgae hydrogel beads, the crushed microalgae hydrogel beads in the annular receiving pan 12 are promptly pushed towards the discharge port 11, preventing the accumulation of crushed microalgae hydrogel beads within the annular receiving pan 12. This allows the crushing device to continuously receive new microalgae hydrogel beads for processing, ensuring the continuity of the entire crushing process and reducing potential problems such as decreased crushing efficiency or equipment blockage caused by the accumulation of microalgae hydrogel beads. This also increases the amount of microalgae hydrogel beads crushed per unit time.

[0051] The method of using a microalgae three-dimensional culture and purification wastewater coupled with aquatic feed preparation device is characterized by the following steps:

[0052] S1. By placing the microalgae hydrogel raw material inside the shaking and distributing component, the shaking and distributing component disperses and evenly feeds the microalgae hydrogel raw material inside into the coarse and fine crushing seat. The coarse and fine crushing seat rotates under the rotation of the shaking and distributing component. At this time, the coarse and fine crushing seat and the crushing core disc are used to crush and prepare the microalgae hydrogel raw material.

[0053] S2. Secondly, under the action of the dispersion component, the crushing core disc rotates along the inside of the coarse and fine crushing seat. During the rotation, the crushing core disc moves slowly and intermittently downward along the inside of the coarse and fine crushing seat. Then, the gap between the coarse and fine crushing seat and the crushing core disc changes continuously. At this time, smaller microalgae hydrogel raw materials fall through the gap onto the surface of the annular receiving plate. The remaining microalgae hydrogel raw materials are still being crushed and prepared during the descent and fall onto the surface of the annular receiving plate.

[0054] S3. Next, the granulation component is used to move the crushing core column downward to a certain position and then push it back. Then the position of the microalgae hydrogel raw material inside the crushing core column and the coarse and fine crushing seat is adjusted, and the microalgae hydrogel raw material continues to be prepared inside the crushing core column and the coarse and fine crushing seat to ensure the quality of feed preparation.

[0055] S4. Subsequently, the microalgae hydrogel bead raw material after crushing and preparation is pushed into the discharge port by the clearing component to process the microalgae hydrogel bead raw material in the annular receiving tray, ensuring the continuity of microalgae hydrogel bead raw material preparation.

[0056] Working principle:

[0057] When using;

[0058] refer to Figure 2 , Figure 3 , Figure 4 ,and Figure 6 As shown, the first servo motor 26 drives the rotating column 27 to rotate inside the crusher frame 1, and the rotating column 27 drives the annular receiving plate 12 to rotate synchronously inside the crusher frame 1. At the same time, the rotating column 27 drives the displacement groove 201 to rotate synchronously. During the rotation of the displacement groove 201, its interior forms an abutment with the annular boss 29 and drives the annular boss 29 to rotate synchronously. Thus, the rotation of the annular boss 29 drives the crushing disc column 28 and the crushing core disc column 14 to rotate synchronously. As the crushing core disc column 14 rotates, it generates pressure at different positions between the microalgae hydrogel raw material on its exterior and the coarse and fine crushing seats 13, which is used to crush and prepare the microalgae hydrogel raw material.

[0059] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the granulation component enables the crushing core disc 14 to slowly move downwards along the interior of the coarse and fine crushing seat 13, satisfying the requirement for multi-directional rotation of the crushing core disc 14. During this process, the crushing core disc 14 can both rotate and slowly move downwards along the interior of the coarse and fine crushing seat 13. Subsequently, the support rod 34 moves downwards synchronously along the interior of the coarse and fine crushing seat 13. The movement of the support rod 34 drives the shifting frame 33 to move downwards synchronously along the interior of the diversion cavity 32. The height difference between the top of the shifting frame 33 and the diversion plate 31 is continuously decreasing. At this time, the shifting frame 33 slides out of the interior of the diversion cavity 32, and there is a gap between the shifting frame 33 and the diversion plate 31. Moreover, the microalgae hydrogel material on the surface of the diversion plate 31 slides down through the diversion cavity 32 into the interior of the coarse and fine crushing seat 13 to fill the interior of the coarse and fine crushing seat 13 with microalgae hydrogel material.

[0060] refer to Figure 7 , Figure 8 and Figure 9 As shown, the crushed microalgae hydrogel material is collected on the surface of the annular receiving tray 12. When the microalgae hydrogel material needs to be quickly discharged from the surface of the annular receiving tray 12 into the interior of the discharge port 11, the third servo motor 45 drives the annular toothed disc 46 to rotate synchronously. Then the annular toothed disc 46 rotates and forms a meshing transmission with the first attached meshing post 51 and several meshing posts 44. At this time, the annular toothed disc 46 moves horizontally along the outside of the first attached meshing post 51 and several meshing posts 44. During the movement, the annular toothed disc 46 drives the moving frame 43 to move horizontally along one side of the stabilizing frame 41 and several meshing posts 44. This causes the moving frame 43 to move synchronously with the limiting frame 53, the guide seat 54 and the pusher plate 42. During this process, the pusher plate 42 moves to push the microalgae hydrogel material on the surface of the annular receiving tray 12, so that the microalgae hydrogel material on the surface of the annular receiving tray 12 moves into the interior of the discharge port 11.

[0061] refer to Figure 7 , Figure 8 and Figure 9 As shown, the pusher plate 42 is driven by the lifting component 5 to make a back-and-forth motion along one side of the stabilizer 41. This helps the pusher plate 42 maintain multiple motion states within the discharge port 11. Its motion state changes from horizontal movement from left to right to upward movement, and then from horizontal movement from right to left to downward movement. This reciprocating operation improves the comprehensiveness and thoroughness of the collection of microalgae hydrogel beads raw materials, which is beneficial to the utilization of microalgae hydrogel beads raw materials.
