Description

Technical Field

[0001] This utility model relates to the field of fermentation equipment technology, specifically to a liquid fermentation device for aquaculture. Background Technology

[0002] Liquid reaction fermentation devices promote the proliferation of beneficial microorganisms (such as lactic acid bacteria or yeast) by providing suitable environmental conditions (such as temperature, humidity or pH value). These microorganisms can decompose the complex components in feed and transform them into nutrients that are more easily digested and absorbed by animals. Therefore, fermentation devices are frequently used in the aquaculture industry.

[0003] A search revealed a patent, CN208327980U, which discloses a liquid fermentation device for livestock farms. The device includes a tank with a retaining seat at the bottom and a retaining ring fitted onto the outer wall of the tank. The retaining ring is connected to the retaining seat via a support rod, which is welded to both the retaining ring and the retaining seat. A support leg is welded to the bottom of the retaining seat. A connecting pipe and a drain pipe are installed at the upper and lower ends of the right side of the tank, respectively. This liquid fermentation device for livestock farms effectively supports the tank by using a retaining seat and a retaining ring, with the retaining ring connected to the retaining seat via a support rod. This increases the stability of the tank during use. Rotating the cap on the exhaust pipe, when the gas inside the tank reaches a certain level, effectively pushes a sliding plate and compresses a first compression spring, facilitating the discharge of gas from the tank and enhancing the efficiency of liquid fermentation, thus meeting user needs.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes a method where the gas produced during fermentation pushes a sliding plate upwards within the inner cavity, connecting the vent, outlet, and inner cavity to expel the gas generated during the fermentation of the aquaculture liquid. However, in reality, a large amount of gas is produced in the initial stage of fermentation, while the amount of gas produced decreases in the later stages. The vent and outlet diameters in the aforementioned comparative document are limited. If the vent and outlet diameters are too small, gas may not be discharged in time during the initial stage of fermentation, and the accumulation of a large amount of gas may push out the cap connected to the exhaust pipe. If the vent and outlet diameters are too large, during the later stages of fermentation, due to the smaller amount of gas discharged, external air may overflow into the tank through the vent and outlet. All of these factors will affect the quality of the fermentation of the aquaculture liquid. Therefore, there is an urgent need in the field to improve the fermentation device for aquaculture liquid to overcome the shortcomings of the prior art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a liquid aquaculture reaction fermentation device to improve the quality of liquid aquaculture reaction fermentation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a liquid reaction fermentation device for aquaculture, comprising a fermentation tank, a discharge port at the lower end of the fermentation tank, a tank cover with a sealing effect at the upper end of the fermentation tank, a first vent pipe with an inner upper cavity larger than an inner lower cavity fixedly connected to the upper part of the tank cover, a second vent pipe with an inner lower cavity larger than an inner upper cavity provided above the first vent pipe, an vent adapted to the first vent pipe on the tank cover, a conical sealing block with an inverted cone shape and a sealing effect provided inside the first vent pipe, an inclined extrusion platform adapted to the side of the conical sealing block provided on the inner side wall of the first vent pipe, and a first elastic spring provided between the conical sealing block and the inner side wall of the second vent pipe.

[0008] Preferably, the conical sealing block has a first arc-shaped groove on its side, and an elastic first sealing ring is embedded in the first arc-shaped groove.

[0009] Preferably, a number of limiting strips are fixedly connected to the upper side of the conical sealing block, and a number of limiting grooves adapted to the limiting strips are opened on the upper cavity side wall of the first air outlet pipe.

[0010] Preferably, the conical sealing block and the inner wall of the second air outlet are both provided with opening slots, and the first spring is placed between the two opening slots.

[0011] Preferably, a threaded connecting ring is fixedly connected to the lower part of the second air outlet pipe, and the threaded connecting ring is threadedly connected to the upper side of the first air outlet pipe.

[0012] Preferably, the inner wall of the tank cover is provided with a plurality of movable grooves, and a meshing plate that is threadedly connected to the upper side of the fermentation tank is movably connected in the movable groove. A movable column that penetrates the tank cover is fixedly connected to one side of the meshing plate. A pull plate is fixedly connected to the outer end of the movable column. A second spring that is sleeved on the side of the movable column is provided between the side of the meshing plate and the inner wall of the movable groove.

[0013] Preferably, the upper part of the fermentation tank and the inner side wall of the tank cover are provided with a second arc-shaped groove, and a second sealing ring with elasticity is embedded in the second arc-shaped groove.

[0014] To address the shortcomings of existing technologies, this utility model provides a liquid fermentation device for aquaculture, overcoming the deficiencies of the prior art. The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, the tension of the first spring pushes the conical sealing block to seal at the position of the inclined extrusion table. When the amount of gas produced during the fermentation of the aquaculture liquid is large, the gas pushes the conical sealing block to move to a higher position. At this time, the gap between the conical sealing block and the inclined extrusion table is large. When less gas is produced during fermentation, the position of the conical sealing block is lower, so the gap between the side of the conical sealing block and the inclined extrusion table is small, or even sealed. The position of the conical sealing block can be adjusted independently according to the amount of fermentation gas. It is suitable for use when different amounts of gas are produced during fermentation, thereby improving the quality of the aquaculture liquid reaction fermentation.

[0016] 2. In this utility model, the first sealing ring is embedded in the first arc-shaped groove. When the tension of the first spring pushes the conical sealing block to move down, the first sealing ring contacts the inclined extrusion table, improving the sealing effect. When the gas generated during fermentation pushes the conical sealing block to move, the limiting strip moves in the opening groove to limit the movement position of the conical sealing block, preventing the conical sealing block from shifting and improving the stability of gas discharge during fermentation.

[0017] 3. In this utility model, pulling the pull plate away from the lid causes the moving column to move the meshing plate in the moving groove, compressing the second spring and completely covering the upper side of the fermentation tank with the lid. Then, the pull plate is released, and the tension of the second spring pushes the meshing plate to move. One side of the meshing plate engages with the threads on the upper side of the fermentation tank. By rotating the pull plate, the lid is tightened. It is not necessary to rotate the lid multiple times, and the lid can be quickly installed on the upper part of the fermentation tank.

[0018] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures pointed out in the description, claims, and drawings. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Please see Figures 1-5 A liquid reaction fermentation device for aquaculture includes a fermentation tank 1, a discharge port 2 at the lower end of the fermentation tank 1, a tank cover 3 with a sealing effect at the upper end of the fermentation tank 1, a first vent pipe 4 with an inner upper cavity larger than the inner lower cavity fixedly connected to the upper part of the tank cover 3, a second vent pipe 5 with an inner lower cavity larger than the inner upper cavity at the upper part of the first vent pipe 4, an vent 6 adapted to the first vent pipe 4 on the tank cover 3, a conical sealing block 7 with an inverted cone shape and a sealing effect inside the first vent pipe 4, an inclined extrusion platform 8 adapted to the side of the conical sealing block 7 on the inner side wall of the first vent pipe 4, and a first elastic spring 9 between the conical sealing block 7 and the inner side wall of the second vent pipe 5.

[0029] In this specific embodiment, when the aquaculture liquid needs to be fermented, the aquaculture liquid to be fermented is injected into the fermentation tank 1. Then, the tank lid 3 is sealed and installed on the upper part of the fermentation tank 1. At this time, due to the tension of the first spring 9, the side of the conical sealing block 7 is in close contact with the position of the inclined extrusion platform 8 inside the first gas outlet pipe 4, achieving the sealing effect of the first gas outlet pipe 4. When the aquaculture liquid ferments and produces gas, the gas will move into the first gas outlet pipe 4 through the gas outlet 6. The gas will push the conical sealing block 7 upward inside the first gas outlet pipe 4, and the side of the conical sealing block 7 will disengage from the position of the inclined extrusion platform 8. The gas will then move into the second gas outlet pipe 5 through the gap between the conical sealing block 7 and the inclined extrusion platform 8. Since the conical sealing block 7 is set in an inverted cone shape, when a large amount of gas is produced during the fermentation of the aquaculture liquid, the gas pushes the conical sealing block 7 to a higher position. At this time, the gap between the conical sealing block 7 and the inclined extrusion table 8 is larger. When less gas is produced during fermentation, the position of the conical sealing block 7 is lower, so the gap between the side of the conical sealing block 7 and the inclined extrusion table 8 is smaller, or even sealed. The position of the conical sealing block 7 can be adjusted according to the amount of fermentation gas. It is suitable for use when different amounts of gas are produced during fermentation, thereby improving the quality of the aquaculture liquid reaction fermentation. The elastic coefficient of the first spring 9 is determined according to the amount of fermented aquaculture liquid. After the fermentation of the aquaculture liquid is completed, it is discharged through the outlet 2.

[0030] Example 2

[0031] Please see Figure 3 and Figure 4 This embodiment includes the above embodiment, and further includes: a first arc-shaped groove 10 is provided on the side of the conical sealing block 7, and an elastic first sealing ring 11 is embedded in the first arc-shaped groove 10; a plurality of limiting strips 13 are fixedly connected to the upper side of the conical sealing block 7; a plurality of limiting grooves 12 adapted to the limiting strips 13 are provided on the upper cavity side wall of the first air outlet pipe 4; opening grooves 14 are provided on the inner side walls of both the conical sealing block 7 and the second air outlet pipe 5; a first spring 9 is placed between the two opening grooves 14; and a threaded connecting ring 15 is fixedly connected to the lower part of the second air outlet pipe 5, and the threaded connecting ring 15 is threadedly connected to the upper side of the first air outlet pipe 4.

[0032] In this embodiment, the first sealing ring 11 is embedded in the first arc-shaped groove 10. When the tension of the first spring 9 pushes the conical sealing block 7 downward, the first sealing ring 11 contacts the inclined extrusion table 8, improving the sealing effect. When the gas generated during fermentation pushes the conical sealing block 7 to move, the limiting strip 13 moves within the opening groove 14, limiting the movement position of the conical sealing block 7 and preventing it from shifting. The cross-section of the limiting strip 13 is as follows: Figure 4As shown, it is diamond-shaped to reduce resistance to gas flow. The open slot 14 is used to limit the first spring 9, and the threaded connecting ring 15 is used to connect the second air outlet 5 to the first air outlet 4.

[0033] Example 3

[0034] Please see Figure 2 and Figure 5 This embodiment includes all the above embodiments, and further includes: a plurality of movable grooves 16 are provided on the inner side wall of the tank cover 3, and a meshing plate 17 is movably connected to the movable groove 16 and threadedly connected to the upper side of the fermentation tank 1. A movable column 19 penetrating the tank cover 3 is fixedly connected to one side of the meshing plate 17, and a pull plate 20 is fixedly connected to the outer end of the movable column 19. A second spring 18 is provided between the side of the meshing plate 17 and the inner side wall of the movable groove 16 and sleeved on the side of the movable column 19. A second arc-shaped groove 21 is provided on the upper part of the fermentation tank 1 and the inner side wall of the tank cover 3, and an elastic second sealing ring 22 is embedded in the second arc-shaped groove 21.

[0035] In this embodiment, the following is a detailed implementation method: When the lid 3 needs to be sealed and installed on the upper part of the fermentation tank 1, the second sealing ring 22 is first embedded in the second arc groove 21. Then, the pull plate 20 is pulled away from the lid 3. The pull plate 20 drives the moving column 19 to move. The moving column 19 drives the meshing plate 17 to move in the moving groove 16. At this time, the second spring 18 is compressed, and the lid 3 is completely covered on the upper side of the fermentation tank 1. Then, the pull plate 20 is released. At this time, the tension of the second spring 18 pushes the meshing plate 17 to move. One side of the meshing plate 17 engages with the threads on the upper side of the fermentation tank 1. At this time, the lid 3 is tightened by rotating the pull plate 20. It is not necessary to rotate the lid 3 multiple times. The lid 3 can be quickly installed on the upper part of the fermentation tank 1.
