Description

Technical Field

[0001] The utility model relates to the technical field of beer fermentation tanks, in particular to a beer fermentation tank component. Background Art

[0002] The beer fermentation process is the normal life activity of brewer's yeast under certain conditions, using the fermentable substances in the wort. The metabolic product of beer is beer. The beer fermentation process is a sterile and pollution-free process, and the beer fermentation process generally uses a fermentation tank. When the fermentation tank is fermenting beer, there is a certain pressure in the tank. As the beer fermentation process progresses, the pressure in the fermentation tank becomes greater and greater. Therefore, during the fermentation process, the pressure in the fermentation tank is promptly relieved and exhausted by observing the pressure gauge on the fermentation tank. However, the exhaust assembly in the existing technology requires manual exhaust, which makes the entire exhaust process complicated to operate and the exhaust effect is poor, resulting in poor quality of the produced beer.

[0015] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-2The top of the pressure rod 10 is hinged with a pressure rod 9, and the front end of the pressure rod 9 is hinged with a connecting plate 8. The bottom end of the connecting plate 8 is hingedly connected to the top of the pressure relief valve 7. By pressing the pressure rod 9, the valve stem on the pressure relief valve 7 is lifted through the connecting plate 8, thereby releasing the pressure inside the pressure chamber 1. Under the action of the pressure difference at both ends of the exhaust pipe 3, the gas in the fermentation tank can be discharged through the exhaust pipe 3; at the same time, the distance between the support rod 10 and the pressure relief valve 7 is smaller than the distance between the tail end of the pressure rod 9 and the support rod 10, thereby forming a labor-saving lever structure, which is convenient for pressing the pressure rod 9;

[0017] A vacuum port 4 is provided on one side of the pressure chamber 1. A vacuum pipe 5 is connected to the vacuum port 4 via a flange. A one-way valve 501 is installed on the vacuum pipe 5 for vacuuming the interior of the fermenter at the start of fermentation.

[0018] An exhaust port 12 is welded to the other side of the pressure chamber 1. A flexible sleeve 11 is installed at the end of the exhaust port 12. The outer side of the flexible sleeve 11 is provided with an external thread for mating with a lock nut. A valve 16 is installed inside the flexible sleeve 11 to ensure the sealing of the interior of the pressure chamber 1. A support washer 19 is installed inside the valve 16 via a fixing bolt 17. A compression spring 18 is installed inside the support washer 19 to press against the support washer 19, thereby ensuring that the support washer 19 presses against the port position of the inserted exhaust pipe, ensuring the sealing of the connection.

[0019] An inner retaining ring 13 is vertically fixed to the inner wall of the exhaust port 12. The upper end of the exhaust pipe 3 extends into the interior of the exhaust port 12 and is fixed in the inner retaining ring 13. The end of the compression spring 18 away from the support washer 19 is fixed to one side of the inner retaining ring 13.

[0020] A connector 15 is installed at the end of the union sleeve 11 , and a sealing ring 14 is installed at the connection between the connector 15 and the union sleeve 11 .

[0021] When the present invention is in use: first, the exhaust pipe is inserted into the connector 15, and the valve 16 is pushed open and extended to the inner side of the valve 16, and then the exhaust pipe is locked and fixed by the cooperation of the locking nut and the flexible sleeve 11, so as to realize the quick connection of the exhaust pipe, and finally, the pressure rod 9 is pressed to drive the connecting plate 8 to move upward, and then the valve stem of the pressure relief valve 7 is pulled to open the pressure relief valve 7, and the pressure inside the pressure chamber 1 is reduced. After the pressure rod 9 is released, the valve stem of the pressure relief valve 7 is reset, resulting in a pressure difference between the two ends of the exhaust pipe 3, and then under the action of air pressure, the gas in the beer fermentation tank is discharged through the exhaust pipe 3 and discharged through the inserted exhaust pipe.

[0022] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
