[0014] This invention provides a fermentation device for fertilizing aquaculture water with a spraying structure. It has the following beneficial effects:

[0015] 1. This fermentation device for aquaculture water and fertilizer with a spraying structure first mixes the additives in the mixing and pushing component through the circulation component, and then disperses the additives and air through the spraying component into the water and fertilizer at different depths inside the fermentation tank, promoting contact between the water and fertilizer, air and additives, increasing the reaction speed and promoting the fermentation of the water and fertilizer.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0031] Example 1: Please refer to Figure 1-7 The present invention provides a technical solution: a fermentation device for aquaculture water fertilization with a spraying structure, including a fermentation tank 1, a feed inlet 2 on the outer wall of the fermentation tank 1, a waste outlet 3 at the bottom of the fermentation tank 1, a detachable end cap at the bottom of the waste outlet 3, a circulation mixing mechanism 5 at the top of the fermentation tank 1, a scraping mechanism 4 inside the fermentation tank 1, the circulation mixing mechanism 5 including a mixing and pushing component 51, the mixing and pushing component 51 being disposed at the top of the fermentation tank 1, a circulation component 52 on the outer wall of the fermentation tank 1, and a spraying component 53 at the top inside the fermentation tank 1.

[0032] Raw materials can be injected into the fermentation tank 1 through the feed inlet 2, allowing the water and fertilizer inside the fermentation tank 1 to undergo a fermentation reaction. The scraping mechanism 4 agitates the reactants inside the fermentation tank 1 to promote the reaction. Simultaneously, the circulation component 52 of the circulating mixing mechanism 5 draws the liquid portion inside the fermentation tank 1 into the mixing and pushing component 51, and then sprays it back into the fermentation tank 1 through the spraying component 53, promoting the circulation of raw materials. In addition, the mixing and pushing component 51 allows the spraying component 53 to inject external air into the liquid inside the fermentation tank 1, promoting the fermentation reaction. Furthermore, when adding adjuvants later, the adjuvants can first come into contact with the liquid inside the mixing and pushing component 51 to promote the diffusion of the adjuvants. Subsequently, the adjuvants are sprayed into the fermentation tank 1 through the spraying component 53 to fully mix with the fermenting water and fertilizer, which is beneficial for promoting the fermentation of water and fertilizer.

[0033] The spraying assembly 53 includes a sliding rail 536, which is fixedly connected inside the fermenter 1. A rotating frame 531 is movably connected to the top of the sliding rail 536. The top of the rotating frame 531 is movably connected to the mixing push assembly 51. Several fixed tubes 532 are fixedly connected to the bottom of the sliding rail 536. A movable sleeve 534 is movably connected to the bottom of the fixed tubes 532. An inner spring 533 is fixedly connected inside the fixed tubes 532. The bottom of the inner spring 533 is fixedly connected to the movable sleeve 534. A spray head 535 is fixedly connected to the outer wall of the movable sleeve 534.

[0034] The top of the connecting shaft 42 is fixedly connected to the bottom of the sliding rail 536. The drive motor 41 drives the sliding rail 536 to rotate through the connecting shaft 42. There are two working modes:

[0035] In mode 1, when the connecting shaft 42 is driven by the drive motor 41 to rotate the sliding rail 536, the flow channel inside the sliding rail 536 remains connected to one of the inner springs 533 for a period of time, and then the sliding rail 536 rotates so that the flow channel rotates to the next inner spring 533 and remains connected.

[0036] Mode 2 slows down the speed at which the mixing push component 51 pushes in air and the speed at which the circulation component 52 pushes in liquid, so that the drive motor 41 drives the connecting shaft 42 to rotate rapidly, which facilitates rapid stirring of the substances inside the fermenter 1 and promotes the reaction.

[0037] In actual use, the device can cycle between mode one and mode two.

[0038] When liquid or gas is continuously pushed into the corresponding fixed tube 532 through the rotating frame 531, the pressure inside the fixed tube 532 increases, causing the corresponding movable sleeve 534 to move under the pressure and stretching the corresponding inner spring 533. Under the tension of the spring, the corresponding spray head 535 continuously sprays out the corresponding gas and liquid. During this process, the movable sleeve 534 moves downward, causing the spray head 535 to move into the liquid, thereby expanding the spraying area of ​​the spray head 535. This promotes better contact between the sprayed gas and additives and the liquid inside the fermenter 1. When the flow moves away from the top of the corresponding inner spring 533, the connection at the top of the inner spring 533 is sealed by the sliding rail 536. At this time, under the elastic force of the inner spring 533, the movable sleeve 534 is pulled back to its original position. This causes the movable sleeve 534 to slowly spray the substance inside the fixed tube 532 through the spray head 535, improving the contact effect of the substance and increasing the fermentation speed.

[0039] After the water and fertilizer fermentation is completed, the end cap at the bottom of the waste outlet 3 can be opened to discharge the water and fertilizer inside the fermentation tank 1. At the same time, the scraping and stirring mechanism 4 can be stirred in the opposite direction to promote the discharge of solid raw materials inside the fermentation tank 1 through the waste outlet 3.

[0040] The mixing push assembly 51 includes a mixing tank 511, which is fixedly connected to the top of the fermentation tank 1. An air compressor 512 is fixedly connected to the top of the mixing tank 511. A feeding port 513 is fixedly connected to the top of the mixing tank 511. A sealing cover that can be opened by rotating the feeding port 513 is provided on the top. The top of the sliding rail 536 is rotatably connected to the bottom of the mixing tank 511 and is provided with a sealing structure.

[0041] The sealing cap on top of the feed inlet 513 can be opened by rotating it. Before opening the sealing cap, the air compressor 512 and the circulation pump 521 must be turned off. At this time, the liquid aid required for fermentation can be added into the mixing tank 511. Then the sealing cap can be reset.

[0042] The sliding rail 536 has a flow channel inside, and the top of the flow channel is connected to the inside of the mixing tank 511, while the bottom of the flow channel can be connected to the inside of the corresponding fixed pipe 532.

[0043] The mixing tank 511 can continuously press external air into the mixing tank 511. Under the action of pressure, the air can be sent into the corresponding fixed pipe 532 through the flow channel inside the sliding rail 536.

[0044] The circulation component 52 includes a circulation pump 521, which is fixedly connected to the outer wall of the fermenter 1. A filter screen is provided at the connection between the circulation pump 521 and the fermenter 1. A connecting pipe 522 is fixedly connected to the top of the circulation pump 521 and is fixedly connected to the outer wall of the mixing tank 511.

[0045] The circulating pump 521 can pump the liquid at the bottom of the fermenter 1 into the mixing tank 511 through the connecting pipe 522. During this process, the filter screen can prevent solid matter from being sucked into the circulating pump 521. The liquid pumped into the mixing tank 511 will be pushed into the flow channel of the sliding rail 536 under pressure, and further enter the corresponding fixed pipe 532.

[0046] The circulation pump 521 can be intermittently reversed to draw liquid, pushing the liquid into the fermenter 1 and pushing the material in the filter screen to the other side, reducing the adhesion of material on one side of the filter screen.

[0047] Example 2: Please refer to Figure 1-10 Based on Embodiment 1, the present invention provides a technical solution:

[0048] The scraping and stirring mechanism 4 includes a drive motor 41, which is fixedly connected to the bottom of the fermentation tank 1. A connecting shaft 42 is fixedly connected inside the fermentation tank 1. The bottom of the connecting shaft 42 is fixedly connected to the output shaft of the drive motor 41. A stirring frame 43 is fixedly connected to the outer wall of the drive motor 41. An agitation component 44 is fixedly connected inside the stirring frame 43.

[0049] The drive motor 41 can drive the connecting shaft 42 to rotate, and drive the stirring frame 43 on the outer wall of the connecting shaft 42 to rotate, so that the stirring frame 43 stirs the fermented water and fertilizer raw materials inside the fermentation tank 1. When the connecting shaft 42 is driven to rotate rapidly, the stirring component 44 can further stir the material inside the fermentation tank 1.

[0050] During the stirring stage, when the stirring frame 43 is rotated, it pushes the material inside the fermentation tank 1 upward, causing the solid material inside the fermentation tank 1 to surge upward. As the material inside the fermentation tank 1 moves towards the edge under the rotation of the stirring frame 43, and the spray head 535 sprays the material towards the center, it promotes the solid material pushed up by the stirring frame 43 to move towards the center area, so as to avoid the solid raw materials from accumulating.

[0051] When it is necessary to discharge the fermented water and fertilizer, the drive motor 41 drives the connecting shaft 42 to rotate in the opposite direction. At this time, when the stirring frame 43 rotates, it will push the material downward and push the solid material to the edge so that the fermentation raw material can be discharged through the bottom of the waste outlet 3.

[0052] In addition, as the stirring frame 43 is driven to rotate, the outer side of the stirring frame 43 can scrape the inner side of the filter screen at the connection between the circulating pump 521 and the fermentation tank 1, so as to prevent too much solid material from adhering to the outer side of the filter screen and affecting the flow of the liquid.

[0053] The stirring assembly 44 includes a fixed rod 441, which is fixedly connected inside the stirring assembly 44. A rotating sleeve 442 is movably connected to the outer wall of the fixed rod 441. An arc-shaped plate 443 is fixedly connected to the outer wall of the rotating sleeve 442. An elastic rod 444 is fixedly connected to the outer wall of the arc-shaped plate 443. When the elastic rod 444 rotates around the fixed rod 441, its outer end will strike the outer wall of the stirring frame 43, causing the surface of the stirring frame 43 to vibrate slightly.

[0054] When the stirring frame 43 is driven to rotate at high speed by the connecting shaft 42, the fluid will flow quickly over the surface of the arc plate 443. Due to the different resistances on the surface of the stirring frame 43, the fluid will push the rotating sleeve 442 to rotate around the fixed rod 441 through the stirring frame 43. The rotation will cause the arc plate 443 to drive the elastic rod 444 on its outer wall to rotate, which can stir the solid raw materials in the fermentation stage in the vertical direction and promote the contact between the solid raw materials and the liquid raw materials.

[0055] When discharging the water and fertilizer raw materials, the elastic rod 444 strikes the surface of the mixing frame 43, which causes the surface of the mixing frame 43 to vibrate, weakening the adhesion of the raw materials on the surface of the mixing frame 43 and promoting the discharge of the raw materials.

[0056] The bottom of the spraying component 53 is fixedly connected to an inner scraper 45, the top of the mixing frame 43 is fixedly connected to a support plate 46, and the top of the support plate 46 is fixedly connected to an elastic pressing plate 47.

[0057] When discharging the raw materials inside the fermenter 1, in Mode 1, the movable sleeve 534 moves downward, pushing the inner scraper 45 downward. This pushes the solid raw materials attached to the inner wall of the fermenter 1 downward. When it pushes the top of the elastic pressing plate 47, the inner scraper 45 presses the elastic pressing plate 47 downward and squeezes the solid material at the bottom of the inner scraper 45 to the edge, squeezing the raw materials into the scraping range of the stirring frame 43, so that this part of the raw materials can be pushed out by the stirring frame 43.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
