Description

Technical Field

[0001] The present invention belongs to the technical field of microbial fermentation, and particularly relates to an intelligent reactor for microbial fermentation and a usage method thereof. Background Art

[0002] Microbial fermentation refers to the process of using microorganisms to convert raw materials into products required by humans through specific metabolic pathways under suitable conditions. The production level of microbial fermentation mainly depends on the genetic characteristics of the strains themselves and the culture conditions. The microbial fermentation process is divided into aerobic fermentation and anaerobic fermentation according to the requirements of fermentation conditions. The aerobic fermentation method includes several methods such as liquid surface culture fermentation, fermentation on the surface of porous or granular solid media, and aerobic deep fermentation. Anaerobic fermentation uses deep fermentation without oxygen supply. Therefore, both aerobic and anaerobic fermentations can be achieved through deep cultivation, and this cultivation is completed in a cylindrical fermentation tank with a certain diameter-to-height ratio.

[0003] However, during the use of traditional microbial fermentation reactors, oxygen is mostly directly introduced into the tank body. The dispersion effect of oxygen up and down is not ideal enough, which is likely to reduce the microbial reaction efficiency. At the same time, raw material residues are easily attached to the inner wall of the tank body, and manual cleaning is required when changing different types of fermentation broth. The tank body cleaning process is rather troublesome and inconvenient to use. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides an intelligent reactor for microbial fermentation and a usage method thereof, which has a stirring structure that can improve the microbial reaction efficiency and a cleaning structure that facilitates people to clean the inner wall of the tank body.

[0005] To achieve the above object, the present invention provides the following technical solution: An intelligent reactor for microbial fermentation and its usage method, comprising a support plate and a tank body. The tank body is fixedly connected inside the support plate. The top of the tank body is fixedly connected with a fixed shell, an oxygen generator, a first rotating motor, and a second rotating motor. The first rotating motor is located inside the fixed shell. The top end inside the tank body is rotatably connected with a rotating pipe through a bearing. The surface of the rotating pipe is fixedly connected with a plurality of cross pipes and a plurality of stirring blades. The surface of the cross pipes is fixedly connected with a plurality of air outlets. The cross pipes and the stirring blades are located inside the tank body. The surface of the rotating pipe is fixedly connected with a first gear, and the first gear is located inside the fixed shell. The output end of the first rotating motor is fixedly connected with a second gear, and the first gear meshes with the second gear. The top of the fixed shell is fixedly connected with a rotary joint, and the top end of the rotating pipe is fixedly connected to the output end of the rotary joint. A connecting pipe is connected between the input end of the rotary joint and the output end of the oxygen generator. An annular groove is opened at the top end inside the tank body, and a meshing groove is opened on the side of the annular groove. An annular block is slidably connected inside the annular groove. The output end of the second rotating motor rotates through the meshing groove and is fixedly connected with a third gear. An annular rack is fixedly connected to the side of the annular block, and the third gear meshes with the annular gear. A plurality of scraping plates are fixedly connected to the bottom of the annular block, and the side of the scraping plates is lapped on the inner side of the tank body. A water spray head is fixedly connected to the top end inside the tank body, and a water inlet pipe is fixedly connected to the top of the tank body. The output end of the water inlet pipe passes through the top of the tank body and is fixedly connected to the input end of the water spray head.

Through the scraper, the materials adhering to the inner wall of the tank can be cleaned. At the same time, the control valve on the surface of the water inlet pipe is opened, and the tank can be sprayed with water through the water spray head, thereby improving the cleaning effect of the inside of the tank;

[0015] Step 4: When the device needs to be moved, the stepping motor operates, which can make the first threaded rod and the second threaded rod rotate, and can drive the two threaded cylinders and the two movable blocks to move on the surfaces of the first threaded rod and the second threaded rod respectively. Through the connecting rod, the wheel frame can be pushed out of the moving box, and under the action of the wheel frame, people can move the device.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

Through the second gear, the rotating pipe, the horizontal pipe and the stirring blades can be driven to rotate. Through the stirring blades and the horizontal pipe, the materials and microbial raw materials can be fully stirred. At the same time, with the cooperation of the oxygen generator to introduce oxygen into the tank, oxygen can be fully contacted with the materials, thereby improving the microbial reaction efficiency. When the second rotating motor operates, the third gear can rotate. Through the engagement of the third gear and the annular rack, the annular block and the scraper can be driven to rotate. Through the scraper, the materials adhering to the inner wall of the tank can be cleaned. At the same time, the control valve on the surface of the water inlet pipe is opened, and the tank can be sprayed with water through the water spray head, thereby improving the cleaning effect of the inside of the tank.

[0018] 2. In the present invention, by providing a pressure sensor and a stepper motor, under the action of the pressure sensor, the pressure inside the tank can be monitored and controlled. Then, through the controller and the electrically controlled air valve, the internal pressure can be controlled, which can prevent the microorganisms inside from being damaged due to excessive pressure.
