[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a microbial inoculant reactor, comprising a support frame 1, one side of four support frames 1 is fixedly connected with a same hollow circular sleeve 3, the inner side of the hollow circular sleeve 3 is fixedly connected with a tank body 4, a tank cover 5 is arranged on the top of the tank body 4, an air pump 6 is fixedly connected to the middle of the top of the tank cover 5, the input end of the air pump 6 is connected with an air inlet pipe 7, the output end of the air inlet pipe 7 passes through the tank cover 5 and is connected with an air outlet pipe 8, the outer bottom of the air outlet pipe 8 is rotatably connected with a hollow tube 9, and a plurality of stirring rods are fixedly connected to the outer side of the hollow tube 9 at equal intervals. 10, the bottom end of the hollow tube 9 is connected with a hollow box 11, and the four sides of the hollow box 11 are connected with aeration pipes 12, and the bottoms of the multiple aeration pipes 12 are evenly spaced and provided with multiple aeration holes 13, a driven gear 14 is fixedly connected to the middle and upper part of the outer side of the hollow tube 9, a servo motor 15 is fixedly connected to the right side of the top of the tank cover 5, the output end of the servo motor 15 passes through the tank cover 5 and is fixedly connected with a driving gear 16, and the driving gear 16 is meshed and connected with the driven gear 14, a temperature control component is arranged inside the hollow sleeve 3, and a cleaning mechanism 2 is arranged inside the tank body 4;

[0031] Specifically, the air pump 6 can continuously draw oxygen from the outside into the tank body 4. This process is crucial because oxygen is an indispensable factor for the growth and metabolism of microorganisms. After oxygen is drawn into the tank body 4, it will be evenly distributed in the microbial culture liquid through the carefully designed aeration pipe 12. At the same time, the servo motor 15 can drive the driving gear 16 to start rotating, because the driven gear 14 and the driving gear 16 are closely connected through a precise meshing relationship. When the driving gear 16 rotates, the driven gear 14 will also rotate, the hollow tube 9 will also rotate, and the stirring rod 10 on the outside will also rotate. They can fully mix the microbial culture liquid and oxygen inside the tank body 4 during the rotation process. Through this mixing method, the solubility of oxygen is significantly increased, thereby ensuring that the microorganisms are always in a suitable growth environment, so as to give full play to their biological activity.

[0032] Reference Figure 2 and Figure 3 The cleaning mechanism 2 includes a hollow ring 201, which is fixedly connected to the inner top of the tank cover 5, and a hollow toothed ring 202 is rotatably connected to the inner side of the hollow ring 201, and the hollow toothed ring 202 is meshedly connected to the driving gear 16, and a plurality of special-shaped scrapers 203 are fixedly connected to the bottom of the hollow toothed ring 202 at equal intervals, and the sizes of the plurality of special-shaped scrapers 203 are matched with the internal size of the tank body 4;

[0033] Specifically, when the driving gear 16 rotates, the hollow tooth ring 202 meshing therewith will also rotate, and the special-shaped scraper 203 at the bottom of the hollow tooth ring 202 will rotate to scrape the microorganisms remaining on the inner wall of the tank body 4. The design of the special-shaped scraper 203 is very clever, and its shape and size have been carefully calculated and optimized to ensure that it can fit closely to the inner wall of the tank body 4, thereby achieving an efficient scraping effect. During the scraping process, the special-shaped scraper 203 can effectively remove the microbial residues on the inner wall of the tank body 4, so that the inner wall of the tank body 4 remains clean, and it is relatively simple for the staff to clean the inner wall of the tank body 4, thereby improving the practicality of the device.

[0034] Reference Figure 1 and Figure 2 The temperature control component includes a condenser 18, which is fixedly connected to the inside of the hollow sleeve 3. The upper and middle right side of the condenser 18 is connected to a liquid inlet pipe 19, and the lower and middle right side of the condenser 18 is connected to a liquid outlet pipe 20. The right ends of the liquid inlet pipe 19 and the liquid outlet pipe 20 both pass through the hollow sleeve 3 and are threadedly connected to a first sealing cover 21. A cavity 22 is provided on the inner side of the tank body 4, and a plurality of heating rods 23 are fixedly connected to the inside of the cavity 22 at equal intervals. A temperature sensor 29 is fixedly connected to the upper and middle left side of the hollow sleeve 3;

[0035] Specifically, the temperature inside the tank body 4 can be monitored in real time through the temperature sensor 29. When the temperature inside the tank body 4 is higher than the maximum temperature set by the temperature sensor 29, the first sealing cover 21 outside the liquid inlet pipe 19 is opened, allowing cooling water to flow into the condenser 18 through the liquid inlet pipe 19. The condenser 18 is located at the periphery of the tank body 4. Through the circulation of cooling water, the heat inside the tank body 4 can be absorbed and taken away, thereby achieving the cooling treatment of the tank body 4. In this process, the flow rate and temperature of the cooling water can be accurately controlled by the system to ensure that the cooling effect is optimal. On the contrary, when the temperature inside the tank body 4 is lower than the minimum temperature set by the temperature sensor 29, the heat released by the heating rod 23 can increase the temperature inside the tank body 4. Through such a set of precise temperature control system, the growth and reaction of microorganisms can always be in the most suitable temperature conditions. This can not only improve the growth rate and reproduction efficiency of microorganisms, but also promote the metabolic activities of microorganisms, thereby accelerating the reaction process and improving the reaction efficiency of the device.

[0036] Reference Figure 1 and Figure 2 The top front side of the tank cover 5 is connected to a liquid inlet 25, the bottom of the tank body 4 is connected to a liquid outlet 24, and one side of the liquid outlet 24 and the liquid inlet 25 are both threadedly connected to a second sealing cover 26;

[0037] Specifically, the liquid inlet 25 can be used to conveniently inject microbial liquid into the tank body 4, and the liquid outlet 24 can be used to collect the cultured microorganisms. The second sealing cover 26 can prevent foreign impurities from entering the tank body 4 and affecting the subsequent reaction of the microbial liquid.

[0038] Reference Figure 1 A controller 27 is fixedly connected to the middle of the left side of the hollow sleeve 3. The controller 27 is electrically connected to the air pump 6, the servo motor 15 and the heating rod 23 respectively. A protective cover 28 is arranged on the outside of the controller 27. One side of the protective cover 28 is rotatably connected to the left side of the hollow sleeve 3.

[0039] Specifically, the operation of the air pump 6, the servo motor 15 and the heating rod 23 can be controlled by the controller 27, and the protective cover 28 can protect the controller 27 from being damaged by external factors.

[0040] Reference Figure 1 and Figure 2 The left and right sides of the tank cover 5 are both threadedly connected with bolts 17, and one end of the bolt 17 passes through the tank cover 5 and the tank body 4 in sequence;

[0041] Specifically, loosening the bolts 17 can release the limit fixation of the tank cover 5, and then the tank cover 5 can be removed to inspect and maintain the structure at the bottom thereof.

[0042] Working principle: When using the device, first open the second sealing cover 26 on the top of the liquid inlet 25, and inject the microbial liquid into the tank body 4 through the liquid inlet 25, then connect the air inlet pipe 7 with the external oxygen tank, and then pump the external oxygen into the tank body 4 through the air pump 6. At this time, the oxygen will enter the microbial liquid through the aeration pipe 12. At the same time, the servo motor 15 can be started to drive the driving gear 16 to rotate, and the driven gear 14 will also rotate due to the meshing with the driving gear 16, thereby driving the hollow tube 9 to rotate. The stirring rod 10 outside the hollow tube 9 will rotate to fully mix the microbial liquid in the tank body 4 with oxygen, which can increase the solubility of oxygen and will not cause some microorganisms to be in an oxygen-deficient state, thereby improving their growth and reaction efficiency, which can meet the needs of users, and the temperature sensor 29 can be used to set the temperature of the microorganism. When the internal temperature of the tank body 4 is higher than the maximum temperature set by the temperature sensor 29, the first sealing cover 21 on the outside of the liquid inlet pipe 19 is opened, and then cooling water is injected into the condenser 18 through the liquid inlet pipe 19 to cool the tank body 4. When the internal temperature of the tank body 4 is lower than the minimum temperature set by the temperature sensor 29, the heating rod 23 is started to heat the tank body 4, so that the growth and reaction of the microorganisms are always in the most suitable temperature conditions, thereby improving the reaction efficiency of the device. When the driving gear 16 rotates, the hollow gear ring 202 will also rotate due to the engagement with the driving gear 16, thereby driving the special-shaped scraper 203 to rotate to scrape the microorganisms remaining on the inner wall of the tank body 4. It is relatively simple for the staff to clean the inner wall of the tank body 4, thereby improving the practicality of the device.
