Description

Technical Field

[0001] This utility model relates to the technical field of plum wine fermentation equipment, and in particular to a pressure relief mechanism and its plum wine fermentation equipment. Background Technology

[0002] The pressure relief mechanism of the plum wine fermentation device refers to the exhaust device designed to prevent excessive pressure inside the device during the fermentation process, when yeast produces carbon dioxide through anaerobic respiration. Its main function is to discharge gases such as carbon dioxide produced during fermentation to maintain pressure balance inside the device and prevent safety hazards such as explosions.

[0003] In traditional plum wine fermentation equipment, the pressure relief mechanism is prone to carrying away residues such as fruit pomace, pulp, and yeast sediment during use. The outlet of the pressure relief mechanism is easily blocked by too much residue, which prevents the pressure from being released in time. In severe cases, this can lead to tank rupture or seal failure, requiring workers to frequently stop the machine for disassembly and cleaning. This downtime for maintenance reduces production efficiency. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figures 1-3 The pressure relief mechanism shown includes an air inlet cylinder 1, a filter screen 10, and a rotary drive mechanism. An elastic mechanism is installed inside the air inlet cylinder 1, which automatically opens and closes according to the system's working pressure. The filter screen 10 is fixedly connected to the inner cavity of the air inlet cylinder 1. A fixing frame 14 is fixedly connected to the inner wall of the inner cavity of the air inlet cylinder 1. A first rotating shaft 13 is rotatably connected to the inner wall of the fixing frame 14. A second rotating shaft 15 is rotatably connected to the upper side of the outer wall of the first rotating shaft 13. The second rotating shaft 15 is perpendicular to the first rotating shaft 13. The first rotating shaft 13 drives the second rotating shaft 15 to rotate around the central axis of the filter screen 10. A brush 17 is fixedly connected to the outer wall. A rotary drive mechanism is located inside the air inlet cylinder 1. The rotary drive mechanism is used to drive the brush 17 to rotate. In specific use, the filter screen 10 inside the air inlet cylinder 1 blocks the residue carried out by the high-pressure gas. At the same time, the high-pressure gas drives the rotary drive mechanism to drive the second rotating shaft 15 to rotate around the central axis of the filter screen 10. The second rotating shaft 15 drives the brush 17 to rotate. The brush 17 removes the residue adhering to the surface of the filter screen 10, thus achieving the purpose of automatic cleaning, preventing the filter screen 10 from clogging, saving workers the process of stopping the machine to disassemble and clean it, and improving work efficiency.

[0023] On one hand, an air outlet 2 is fixedly connected to the outer wall of the air inlet cylinder 1, and an end cap 3 is movably connected to the top of the air inlet cylinder 1. A bolt 4 is threaded between the end cap 3 and the air inlet cylinder 1, connecting the end cap 3 and the air inlet cylinder 1 for easy disassembly and maintenance. The elastic mechanism includes a first fixed plate 9, which is fixedly connected to the inner wall of the air inlet cylinder 1. A stop plate 8 is movably connected to the inner wall of the first fixed plate 9, and a sealing ring is provided on the outer wall of the stop plate 8 to prevent leakage during fermentation and improve the sealing effect. The stop plate 8 and the first fixed plate 9 are positioned above the filter screen 10. A spring 7 is fixedly connected between the stop plate 8 and the end cap 3, and a circular rod 6 is slidably connected to the outer wall of the end cap 3. When the air pressure reaches a certain level, a spring 7 is released. When the pressure is high, the pressure on the abutment plate 8 causes it to move, and the abutment plate 8 compresses the spring 7. After the air pressure is released, the spring 7 resets, causing the abutment plate 8 to reset until the abutment plate 8 and the first fixed plate 9 are back together, ensuring a sealing effect. The end cover 3 has a sliding rod 5 slidably connected to its inner cavity. A circular rod 6 is fixedly connected to the bottom of the sliding rod 5, and the abutment plate 8 is fixedly connected to the bottom of the circular rod 6. In specific use: when the air pressure inside the device is too high, the air pressure compresses the abutment plate 8 until the abutment plate 8 and the first fixed plate 9 are no longer together, forming a vent. At the same time, the spring 7 is compressed to achieve a pressure relief effect. When the air pressure inside the device drops to a suitable level, the spring 7 resets, causing the abutment plate 8 to reset and back together with the first fixed plate 9.

[0024] On the other hand, the filter screen 10 is set above the fixed frame 14. The rotation drive mechanism includes blades 12, which are fixedly connected to the outer wall of the first rotating shaft 13. When high-pressure gas passes through the air inlet cylinder 1, the air pressure drives the blades 12 to rotate, causing the brush 17 to come into contact with the filter screen 10. A second bevel gear 16 is fixedly sleeved on the outer wall of the second rotating shaft 15. A second fixed plate 18 is fixedly connected to the middle of the outer wall of the filter screen 10. A first bevel gear 11 is fixedly connected to the bottom of the second fixed plate 18. The first bevel gear 11 and the second bevel gear 16 mesh with each other. The brush 17 rotates when it rotates around the central axis of the filter screen 10, thanks to the action of the first bevel gear 11 and the second bevel gear 16. In practical use: air pressure drives the blade 12 to rotate, the blade 12 drives the first rotating shaft 13 to rotate, the first rotating shaft 13 rotates through the second rotating shaft 15 and the brush 17, and under the action of the first bevel gear 11, the second rotating shaft 15 rotates on its own, the second rotating shaft 15 drives the brush 17 to rotate on its own, thereby improving the cleaning effect of the brush 17 on the filter screen 10.

[0025] This embodiment also provides a plum wine fermentation device, including the aforementioned pressure relief mechanism.

[0026] In specific operation: When the internal air pressure of the device is too high, the air pressure compresses the abutment plate 8 to move until the abutment plate 8 no longer abuts the first fixed plate 9, forming a vent. At the same time, the spring 7 is compressed to achieve the pressure relief effect. The air pressure drives the blade 12 to rotate, and the blade 12 drives the first rotating shaft 13 to rotate. The first rotating shaft 13 rotates through the second rotating shaft 15 and the brush 17. Under the action of the first bevel gear 11, the second rotating shaft 15 rotates on its own axis, and the second rotating shaft 15 drives the brush 15 to rotate on its own axis, completing the purpose of automatic cleaning and preventing the filter screen 10 from being blocked. When the internal air pressure of the device drops to a suitable air pressure, the spring 7 resets and drives the abutment plate 8 to reset, abutting the first fixed plate 9 again.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
