Description

Technical Field

[0001] The utility model relates to the technical field of fermentation, in particular to a digital display type fermentation tank. Background Art

[0002] A fermenter is a device used for microbial fermentation. Typically made of stainless steel, it has a cylindrical main body and a volume ranging from one to several hundred cubic meters. It typically features a stirring paddle to disperse bubbles and introduce oxygen to meet the metabolic needs of the microorganisms. It is widely used in the pharmaceutical, dairy, beverage, bioengineering, and fine chemical industries to cultivate microorganisms and enable them to grow efficiently and secrete target products.

[0003] Existing fermentation tanks usually require a thermometer to be placed inside to monitor the internal temperature when performing temperature detection. This detection method is relatively cumbersome, and the top temperature measured in the fermentation tank is higher than the actual temperature, and the temperature accuracy is also low. At the same time, the existing stirring blades are usually fixed and the inclination angle of the stirring blades cannot be changed. It is difficult to ensure the mixing effect of the fermentation products when facing different materials. Utility Model Content

[0004] The purpose of the present utility model is to provide a digital display fermentation tank in order to solve the above problems. The connecting wires and thermometer in the digital display are directly connected to the inner bottom surface of the tank body to measure the temperature of the fermented material. The threaded turntable with a lifting sleeve surrounds the external thread of the connecting threaded rod, and rises and falls with the lifting sleeve to change the inclination angle of the arrow-shaped stirring blade in the connecting stirring mechanism, thereby improving the mixing effect and fermentation efficiency.

[0030] By adopting the above technical solution, the supporting bent rod 2 provides supporting force for the driving motor 4, so that the driving motor 4 is fixed in a suitable position to drive the internal connecting stirring mechanism 6. After being driven, the connecting stirring mechanism 6 stirs the fermented material inside the tank body 1 to make it fully fermented. The output end of the driving motor 4 is fixed with a connecting threaded rod 5 so that the connecting threaded rod 5 cannot rotate. The threaded connecting rod 606 is fixed and cooperated with the threaded turntable 7 to adjust the height of the lifting sleeve 8 to adapt to different fermented materials. The rotating sleeve 9 is between the middle of the top side of the tank body 1 and the lifting sleeve 8 to help the lifting sleeve 8 rotate in the tank body 1. The connecting threaded rod 5 and the connecting stirring mechanism 6 are in a sleeve relationship. The connecting threaded rod 5 is on the outside, and the rotation of the inner connecting stirring mechanism 6 will not affect the connecting threaded rod 5. The supporting bent rod 2, the rotating sleeve 9 and the digital display 3 are L-shaped, so that the staff can more intuitively observe the status of each structure and facilitate timely adjustment.

[0031] See also Figure 6 As shown, the digital display 3 includes a display screen 301, a connecting line 302 is fixedly provided on the bottom side of the display screen 301, one end of the connecting line 302 is connected to a thermometer 303, and the connecting line 302 passes through the lower position of the can body 1 and extends to the middle position inside the can body 1;

[0032] When in use, the connecting line 302 is connected to the bottom of the display screen 301, and extends to the inside of the tank body 1 in a C shape, and finally connected to the thermometer 303 to detect the temperature of the fermented material in the tank body 1 and display the temperature on the display screen 301, so that the staff can make corresponding adjustments to the temperature of the internal fermented material in time.

[0033] See also Figure 4-Figure 7As shown, the connecting stirring mechanism 6 includes a transmission shaft 601, a connecting rod 606 is fixedly provided at the lower end of the transmission shaft 601, a rotating rod 602 is fixedly provided at the lower end of the connecting rod 606, a plurality of hinged disks 603 are hingedly provided on the outer surface of the rotating rod 602, an arrow-shaped stirring blade 604 is fixedly provided on the side of the hinged disk 603 away from the rotating rod 602, a limiting disk 605 is fixedly provided at the lower end of the rotating rod 602, and the rotating rod 602 is a pentagonal long rod.

[0034] Using the above embodiment, after being driven by the driving motor 4, the transmission shaft 601 rotates with the rotating rod 602 through the connecting rod 606 on the bottom side, and the rotating rod 602 rotates with the multiple hinged disks 603 on its own surface and the arrow-shaped stirring blades 604 inside the tank body 1 to stir the fermented material and improve the mixing effect. The arrow-shaped stirring blades 604 have strong comprehensive performance, and are better at crushing bubbles and turning over liquids. At the same time, they are also more conducive to use with the lifting sleeve 8.

[0035] See also Figure 4-Figure 7 As shown, the lifting sleeve 8 includes a connecting sleeve 801, and a lifting shell 802 is fixedly provided on the bottom side of the connecting sleeve 801. The connecting sleeve 801 and the lifting shell 802 are both hollow. A plurality of elliptical holes 803 are opened on the outer surface of the lifting shell 802, and the lifting shell 802 is pentagonal.

[0036] When in use, the five sides of the lifting shell 802 correspond to the five sides of the rotating rod 602. The hollow setting provides space for the rotating rod 602 to facilitate the placement of the rotating rod 602. The elliptical hole 803 allows the hinge plate 603 to pass through. At the same time, when the lifting shell 802 is lifted, the hinge plate 603 is rotated through the elliptical shell, changing the inclination angle of the arrow-shaped stirring blade 604 on one side of the hinge plate 603, so that the inclination angle of the arrow-shaped stirring blade 604 is upward or downward, thereby improving the mixing effect of the fermentation product.

[0037] With the above structure, after the staff starts the drive motor 4, the output end of the drive motor 4 directly drives the transmission shaft 601 connected to the stirring mechanism 6 to rotate. The transmission shaft 601 drives the connecting rod 606 and the rotating rod 602 on the bottom side to maintain a consistent rotation speed. The rotating rod 602 rotates with the multiple hinged plates 603 and arrow-shaped stirring blades 604 provided on the surface, stirring the items to be fermented inside the tank body 1, thereby improving the fermentation efficiency.

[0038] When the density of the fermented materials is different, the staff can rotate the threaded turntable 7 to make the threaded turntable 7 rotate on the outside of the connected threaded rod 5 to rise or fall, and pull the lifting shell 802 up or down through the connecting sleeve 801 on the bottom side. At the same time, the elliptical hole 803 opened through the outer surface of the lifting shell 802 is used to rotate the hinged disk 603 to complete the lifting and lowering of the arrow-shaped stirring blade 604, adapting to different fermented materials, and evenly stirring the fermented materials to improve the fermentation effect. The display screen 301 is connected to the thermometer 303 inside the tank body 1 through the connecting line 302, and the temperature of the thermometer 303 is displayed on the display screen 301, which is convenient for the staff to intuitively check the temperature of the fermentation liquid inside the tank body 1.
