DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments in 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.
[0024] like Figure 1-4 As shown, the utility model provides a mixing tank for fruit and vegetable fermentation with an emergency pressure relief function, comprising a circular tank top plate 1, a cylindrical tank barrel 2, a funnel-shaped tank bottom hopper 3 and a mixing mechanism;
[0025] The bottom surface of the tank top plate 1 is correspondingly covered on the top of the tank barrel 2, and the top of the tank bottom hopper 3 is correspondingly sealed and connected to the bottom end of the tank barrel 2. A discharge port is provided at the bottom center of the tank bottom hopper 3, and the discharge port is equipped with a discharge valve 4 for opening and discharging after the fermentation is completed; a plurality of groups of locking buckles 22 are evenly provided between the circumferential edge of the tank top plate 1 and the outer edge of the top end of the tank barrel 2, and the tank top plate 1 and the tank barrel 2 are connected by the locking buckles 22. A sealing ring is provided on the bottom surface of the tank top plate 1 at the position where it contacts the tank barrel 2, so that the sealing of the tank body is guaranteed during the fermentation process. A lifting lug 23 for lifting the tank top plate 1 is provided on the top surface of the tank top plate 1, which facilitates the movement of the entire tank top plate 1 and the mixing mechanism.
[0026] The mixing mechanism includes a drive motor 5, a coupling 6, a stirring shaft 7, and a stirring paddle 8. A drive port is provided through the center of the tank top plate 1, and the coupling 6 is provided inside the drive port. The stator end of the drive motor 5 is fixedly connected to the top surface of the tank top plate 1, and the rotor end of the drive motor 5 is fixedly connected to the stirring shaft 7 through the coupling 6. The stirring paddle 8 is connected to the outer side of the stirring shaft 7; after the drive motor 5 is started, its rotor end drives the stirring shaft 7 to rotate through the coupling 6, and drives the stirring paddle 8 to rotate inside the tank body, thereby stirring and mixing the fruit and vegetable raw materials on a large scale, so that the fermentation progress of the fruit and vegetable raw materials inside the tank body is consistent and the fermentation quality is higher.
[0027] like Figure 2As shown, a barometer and at least two automatic pressure relief valves 11 are provided on the tank top plate 1. The sensing end 9 of the barometer is provided on the bottom surface of the tank top plate 1, and the display end 10 of the barometer is provided on the side or top of the tank top plate 1. The tank top plate 1 is provided with a pressure relief hole, and the automatic pressure relief valve 11 is fixedly provided inside the pressure relief hole. The barometer is used to measure the internal air pressure of the tank body and display it, making it convenient for staff to understand the internal air pressure of the tank body. The automatic pressure relief valve 11 has a certain pressure relief threshold value. When the threshold value is reached, it can automatically relieve the pressure, which can greatly improve safety during the fermentation process.
[0028] The working principle, use process and technical advantages of the mixing tank for fruit and vegetable fermentation of the present invention are as follows: in actual use, the tank top plate 1 is first lifted to release the top of the tank barrel 2, and the pulped or crushed fruit and vegetable raw materials are put into the mixing tank from the top of the tank barrel 2. After the fruit and vegetable raw materials are fully put in, the tank top plate 1 is lowered, and the tank top plate 1 and the tank barrel 2 are fixedly connected. During the fermentation process, by starting the driving motor 5, the stirring paddle 8 is driven to rotate and stir inside the tank body to achieve mixing of the fruit and vegetable raw materials. The air pressure inside the tank body can be obtained by the barometer, and the automatic pressure relief valve 11 can be selectively controlled to perform pressure relief. When the air pressure inside the tank body increases rapidly and is not handled in time by humans, causing the air pressure inside the tank body to reach the automatic pressure relief pressure value of the automatic pressure relief valve 11, the automatic pressure relief valve 11 can automatically open to relieve pressure, thereby avoiding safety accidents caused by excessive air pressure. In addition, at least two automatic pressure relief valves 11 are provided to increase the probability of smooth pressure relief and reduce the situation where the air pressure cannot be released due to failure of the automatic pressure relief valve 11. The entire mixing tank can support air pressure display and can also automatically release pressure in an emergency. The pressure relief operation is more timely and efficient. The raw material mixing operation is convenient, and the safety level is greatly improved, thereby improving the fermentation quality.
[0029] As an embodiment of the present invention, Figure 3 and 4 As shown, the automatic pressure relief valve 11 includes an installation valve tube 12, a pressure relief plug plate 13, a pressure relief spring 14, a pressure relief telescopic rod 15, a pressure relief limit block 16 and two limit rods 17; the outside of the installation valve tube 12 is fixedly connected to the inside of the pressure relief hole, and the two limit rods 17 are fixedly installed horizontally and parallel to the inside of the installation valve tube 12, the top and bottom ends of the pressure relief telescopic rod 15 are respectively fixedly connected to the bottom surface of the pressure relief plug plate 13 and the top surface of the pressure relief limit block 16, the top and bottom ends of the pressure relief spring 14 are also respectively fixedly connected to the bottom surface of the pressure relief plug plate 13 and the top surface of the pressure relief limit block 16, the pressure relief spring 14 is sleeved on the outside of the pressure relief telescopic rod 15, the bottom surface of the pressure relief plug plate 13 is in contact with the top edge of the installation valve tube 12, the top surface of the pressure relief limit block 16 is in contact with the bottom surfaces of the two limit rods 17, and the bottom end of the pressure relief telescopic rod 15 is arranged between the two limit rods 17.
[0030] The key structure for the automatic pressure relief valve 11 to trigger the automatic pressure relief operation lies in the elastic coefficient, length and other elastic parameters of the pressure relief spring 14. By selecting springs of different lengths or elastic coefficients, the threshold value of the automatic pressure relief can be adjusted, so that flexible selection can be made according to the type of fruit and vegetable raw materials to be fermented, so that the fermentation has higher quality.
[0031] During the fermentation process, when the air pressure inside the tank gradually increases, the pressure relief plug plate 13 will continue to be pushed toward the top. However, due to the presence of the limit rod 17, the pressure relief limit block 16 and the pressure relief spring 14, a downward pulling force is applied to the pressure relief plug plate 13. When the thrust is greater than the pulling force, a part of the pressure relief plug plate 13 will detach from the top of the mounting valve tube 12, thereby achieving automatic pressure relief.
[0032] Specifically, a manual pressure relief handle 18 is provided on the top of the pressure relief plug plate 13, which is convenient for manual pressure relief by pulling outward. A sealing gasket is also provided on the bottom edge of the pressure relief plug plate 13, so that the automatic pressure relief valve 11 has better sealing performance.
[0033] As an embodiment of the present invention, Figure 1 As shown, the stirring paddle 8 includes at least one scraping paddle 19 and a plurality of stirring connecting rods 20. The outer edges of the scraping paddle 19 respectively adhere to the inner wall of the tank barrel 2 and the inner wall of the tank bottom hopper 3. The two ends of the stirring connecting rod 20 are respectively fixedly connected to the inner side of the scraping paddle 19 and the shaft of the stirring shaft 7. This prevents the fruit and vegetable raw materials from sticking to the inner wall of the tank during the mixing operation, thereby ensuring more complete fermentation and facilitating the cleaning of the tank body later.
[0034] As one embodiment of the present invention, the barometer is also equipped with an audible and visual alarm 21. The barometer supports setting the air pressure value and triggering the alarm. When the barometer detects that the air pressure in the mixing tank reaches a preset value, the power switch of the audible and visual alarm 21 is triggered. The audible and visual alarm 21 is installed on the top surface or side of the tank roof 1. In other words, the barometer is a barometer that can alarm. When the set value is reached, the alarm sounds, which facilitates prompting manual processing.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
