Description

Technical Field

[0001] The present invention relates to the technical field of fermentation tanks, and in particular to a fermentation tank cleaning and disinfection device and method. Background Art

[0002] As the core equipment in the biological fermentation process, the cleanliness of the fermentation tank is directly related to the product quality. During the use of the fermentation tank, it is easy to be contaminated by external microorganisms, such as bacteria, molds and viruses. If it is not cleaned and disinfected, these microorganisms will breed and multiply in the tank, compete with the fermentation bacteria for nutrients, affect the normal fermentation, and may even cause fermentation failure, resulting in economic losses. In addition, the substances produced during the fermentation process may cause corrosion and wear to the inner wall and components of the fermentation tank. If not cleaned in time, these substances will gradually accumulate, aggravate the corrosion and wear of the equipment, and shorten the service life of the equipment. Regular cleaning and disinfection can remove these harmful substances, protect the inner wall and components of the equipment, and extend the service life of the equipment.

The mobile trolley is provided with a liquid storage mechanism for storing a cleaning medium, a lifting mechanism for lifting movement, and a liquid supply mechanism for conveying the cleaning medium. The lifting mechanism is provided with a blowing mechanism for providing high-pressure air and a rotating mechanism for rotary cleaning. When the fermentation tank is disinfected, the rotating mechanism sprays disinfectant onto the inner wall of the fermentation tank, thereby disinfecting the inner wall of the fermentation tank.

[0004] In the above technology, when disinfecting the inner wall of the fermentation tank, disinfection is performed by spraying disinfectant. The disinfectant cannot remain on the inner wall of the fermentation tank for a long time, and the range of spraying disinfection at the same time is limited.

At this time, the internal gas of the airbag 34 is discharged to the outside of the airbag 34 through the electromagnetic valve during the winding process.

[0049] The specific implementation method of the present invention for cleaning and disinfecting the fermentation tank 1 is as follows:

[0050] S1. First, the motor 5 drives the screw 2 25 to rotate, so that the slider drives the stirring shaft 22 to move coaxially with the fermentation tank 1, and then the motor 1 drives the screw 1 321 to rotate so that the two mounting rings 322 approach each other, thereby moving the cleaning rod 31 toward the inner wall of the fermentation tank 1;

[0051] S2. When the cleaning rod 31 moves toward the inner wall of the fermentation tank 1, the electric telescopic cylinder drives the connecting rod 1 331 to extend from the cleaning rod 31, and at the same time, the nozzle 333 sprays water toward the inner wall of the fermentation tank 1, and the motor 4 23 drives the rotating shaft to rotate, thereby causing the connecting plate 21 to drive the stirring shaft 22 to rotate through the slider, thereby increasing the range of the nozzle 333 spraying water;
