Technical Field

[0001] The present invention relates to the technical field of mature vinegar brewing, and more specifically, to an aging tank for mature vinegar fermentation. Background Art

[0002] Traditional aging tanks for mature vinegar fermentation mostly adopt a single spraying or stirring structure, which has problems such as low dissolved oxygen efficiency, incomplete tank cleaning, and temperature control lag. For example, the fixed spraying device cannot balance the functions of atomizing oxygenation and high-pressure flushing, resulting in limited proliferation of acetic acid bacteria and easy growth of contaminants from residues; the structure of the stirring device is fixed and lacks an effective dissolved oxygen design, affecting the uniformity of fermentation.

[0003] The Chinese utility model patent with the publication number CN215480833U discloses a fully automatic solid-state vinegar fermentation device, which is provided with a spraying device and a stirring device inside the fermentation device body to accelerate the fermentation process through stirring and spraying. However, the conventional stirring device has a small disturbance to the liquid, resulting in low dissolved oxygen efficiency.

[0004] The Chinese utility model patent with the publication number CN214142320U discloses a fermentation tank with a special cleaning part, including a tank body and a stirring part and a cleaning part installed on its top. Its cleaning part uses a fixed nozzle for flushing, and it is difficult to achieve the cleaning of the entire tank body.

[0005] Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0011] Preferably, vertical guide rails are arranged on the outer side of the inner sleeve, and positioning blocks cooperating with the vertical guide rails are arranged on the inner side of the outer sleeve. When the outer sleeve moves downward to the maximum stroke, the positioning blocks do not contact the vertical guide rails.

[0012] Preferably, a heat preservation sleeve is arranged on the outer side of the tank body. A water outlet and a water inlet are respectively arranged at the upper and lower ends of the heat preservation sleeve, and electric heating wires are arranged in the heat preservation sleeve.

[0013] Preferably, triangular through holes are arranged on the stirring blades.

[0018] 2. A ventilation pipeline is provided on the stirring blade of the present invention. Utilizing the air flow formed during stirring, air is introduced into the deep layer of the vinegar liquid through the pipeline to achieve efficient dissolved oxygen; the telescopic stirring rod (inner / outer sleeve structure) cooperates with the clamping and positioning device to ensure that the stirring blade does not interfere with the tank body. The bending part and the triangular through-hole design can not only enhance the liquid turbulence mixing effect but also prevent the vinegar liquid from blocking the ventilation pipeline.

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. Embodiment

[0024] As Figures 1 to 12 shown, an aging tank for mature vinegar fermentation includes a tank body 1, a spraying device 2 and a stirring device 3. The spraying device 2 includes a self - priming pump 21 and a hollow ring 22 arranged at the upper opening of the tank body 1. A number of first spray heads 23 and second spray heads 24 are arranged on the hollow ring 22. Preferably, the first spray head 23 adopts an atomizing spray head, and by pumping vinegar liquid and spraying it out from the first spray head 23, the dissolved oxygen in the vinegar liquid is increased, accelerating the proliferation of acetic acid bacteria. The second spray head 24 adopts a flat - mouth flushing spray head, and when the second spray head 24 works, it faces the inside of the tank body 1 for cleaning the tank body 1.

[0025] The self - priming pump 21 is connected to the hollow ring 22 through a pipeline. A liquid outlet is arranged at the lower end of the tank body 1. The liquid inlet of the self - priming pump 21 is connected with a tee pipe I 25. One of the liquid inlet pipelines of the tee pipe I 25 is communicated with the liquid outlet of the tank body 1, and the other liquid inlet pipeline of the tee pipe I 25 is used for connecting a cleaning liquid device; solenoid valves 26 for controlling the on - off of the corresponding pipelines are arranged on both liquid inlet pipelines of the tee pipe I 25.

[0026] When the first nozzle 23 works, the three-way pipe I 25 is controlled to communicate with the liquid outlet of the tank body 1, and the vinegar liquid is extracted by the self-priming pump 21 for spraying. When the second nozzle 24 works, the three-way pipe I 25 is controlled to communicate with the cleaning liquid equipment, and the cleaning liquid equipment is used to provide the cleaning liquid, and the self-priming pump 21 extracts the cleaning liquid to clean the inner wall of the tank body 1.

[0027] In order to facilitate the switching between the work of the first nozzle 23 and the second nozzle 24, a plurality of columnar structures 27 fixedly connected to the hollow ring 22 are arranged circumferentially on the hollow ring 22. The first nozzle 23 and the second nozzle 24 are both rotatably arranged on the columnar structures 27 through the mounting rings 28. Preferably, one first nozzle 23 and one second nozzle 24 are arranged on each mounting ring 28. An opening I 29 communicating with the inside of the hollow ring 22 is arranged on the outer cylindrical surface of the columnar structure 27. The hollow ring 22 is connected with a driving structure 4 for driving a plurality of mounting rings 28 to rotate synchronously. When the mounting ring 28 rotates, one of the first nozzle 23 and the second nozzle 24 communicates with the opening I 29; when the opening I 29 communicates with the first nozzle 23, the liquid in the hollow ring 22 is ejected through the first nozzle 23; when the opening I 29 communicates with the second nozzle 2, the liquid in the hollow ring 22 is ejected through the second nozzle 24.

[0028] The driving structure 4 includes a control ring 41 arranged parallel to the hollow ring 22. The control ring 41 is slidably arranged in the tank body 1 in the vertical direction. Tooth teeth 210 are arranged on the mounting ring 28, and a rack 43 meshing with the tooth teeth 210 is fixedly arranged on the control ring 41. A lifting control device 42 is arranged between the control ring 41 and the hollow ring 22. By changing the distance between the control ring 41 and the hollow ring 22 through the lifting control device 42, the rack 43 is driven to move relative to the tooth teeth 210, so that the mounting ring 28 rotates relative to the columnar structure 27.

[0029] The lifting control device 42 can adopt a guide rod 44 and an electromagnetic push rod 45. Specifically, the guide rod 44 is fixedly arranged on the control ring 41. A connecting platform is arranged on the hollow ring 22, and a jack slidably matched with the guide rod 44 is arranged on the connecting platform. The electromagnetic push rod 45 is arranged on the connecting platform, and the working end of the electromagnetic push rod 45 is connected to the control ring 41.

[0030] A lifting screw rod 15 is arranged between the control ring 41 and the tank body 1. The lifting screw rod 15 is rotatably connected to the tank body 1, and a threaded hole threadedly matched with the lifting screw rod 15 is arranged on the control ring 41. The upper end of the lifting screw rod 15 is connected with a motor 16 through a belt transmission mechanism.

[0031] When cleaning is required, the lifting screw rod 15 is controlled to rotate, driving the control ring 41 and the hollow ring 22 to move up and down, and then the inner wall of the tank body 1 is comprehensively cleaned through the second nozzle 24.

[0032] The stirring device 3 includes a movable support frame 35, a stirring rod 31, and stirring blades 32 provided on the stirring rod 31. Bent portions 33 are provided on both sides of the stirring blades 32. A ventilation pipeline 34 is provided on the stirring blades 32. The two ends of the ventilation pipeline 34 are respectively provided on the two bent portions 33 and have the same bending direction as the bent portions 33.

[0033] The lower side of the stirring blade 32 is below the liquid level, and the upper side of the stirring blade 32 is above the liquid level. When the stirring rod 31 drives the stirring blade 32 to rotate, a micro-negative pressure is formed behind the lower side of the stirring blade 32, driving air to flow from the upper end to the lower end of the ventilation pipeline 34 and mixing with the vinegar liquid. Triangular through holes 313 are provided on the stirring blades 32 to facilitate the passage of the vinegar liquid and prevent the vinegar liquid from entering the ventilation pipeline 34.

[0034] A clamping and positioning device 5 that cooperates with the bottom of the tank body 1 is provided at the lower end of the movable support frame 35 to facilitate the alignment of the stirring rod 31 with the tank body 1. Specifically, the clamping and positioning device 5 includes a first V-shaped block 51 and a second V-shaped block 52 that are oppositely arranged. The first V-shaped block 51 is fixedly connected to the movable support frame 35, the second V-shaped block 52 is slidably connected to the movable support frame 35, and a linear drive 53 for driving the second V-shaped block 52 to approach or move away from the first V-shaped block 51 is provided on the movable support frame 35.

[0035] The stirring rod 31 includes an inner sleeve 36 and an outer sleeve 37 that are slidably fitted. The upper end of the inner sleeve 36 is fixedly connected to the top of the movable support frame 35. An internally threaded sleeve 38 is coaxially and fixedly connected to the middle of the outer sleeve 37. A drive motor 310 is provided on the movable support frame 35. The motor shaft of the drive motor 310 is connected to a drive screw 39. The lower end of the drive screw 39 is threadedly connected to the internally threaded sleeve 38. A vertical guide rail 311 is provided on the outside of the inner sleeve 36, and a positioning block 312 that cooperates with the vertical guide rail 311 is provided on the inside of the outer sleeve 37. When the drive motor 310 drives the drive screw 39 to rotate, due to the circumferential limit between the vertical guide rail 311 and the positioning block 312, the outer sleeve 37 moves downward relative to the inner sleeve 36, so that the lower end of the outer sleeve 37 extends into the tank body 1.

[0036] When the outer sleeve 37 moves downward to the maximum stroke, the positioning block 312 does not contact the vertical guide rail 311, that is, the positioning block 312 is lower than the lowest end of the vertical guide rail 311. At this time, the lower end of the drive screw 39 and the upper end of the internally threaded sleeve 38 are axially limited, and the drive screw 39 drives the outer sleeve 37 to rotate synchronously, thereby driving the stirring blades 32 to rotate.

[0037] After the stirring is completed, the driving motor 310 drives the driving screw 39 to rotate reversely. By utilizing the speed difference between the driving screw 39 and the internal-thread sleeve 38, the internal-thread sleeve 38 moves upward relative to the driving screw 39 until the positioning block 312 contacts the vertical guide rail 311. The rotation of the outer sleeve 37 is restricted by the vertical guide rail 311. The driving motor 310 continues to rotate, driving the outer sleeve 37 to move upward continuously.

[0038] A heat-insulating sleeve 11 is arranged outside the tank body 1. Water outlets 12 and water inlets 13 are respectively arranged at the upper and lower ends of the heat-insulating sleeve 11. An electric heating wire 14 is arranged inside the heat-insulating sleeve 11. When the temperature needs to be raised, the liquid inside the heat-insulating sleeve 11 is heated by the electric heating wire 14. When the temperature needs to be lowered, cooling water is continuously injected through the water inlet 13 to cool the liquid in the tank.

[0039] The liquid outlet is connected to a three-way pipe II 17. One of the liquid outlet pipelines of the three-way pipe II 17 is communicated with the three-way pipe I 25. A discharge control valve 18 for controlling the discharge is arranged on the other liquid outlet pipeline of the three-way pipe II 17.

[0040] Only the preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention, and all such changes should be included within the protection scope of the present invention.
