Description

Technical Field

[0001] The utility model relates to the technical field of strain cultivation, and particularly relates to a strain cultivation environment adjustment component and a strain cultivation device applying the component. Background Art

[0002] The working principle of the aerobic fermentation treatment technology for kitchen waste is to mix kitchen waste and biomass auxiliary materials evenly in a certain proportion, and in the fermentation tank, by adjusting the moisture, microbial inoculum, oxygen content and temperature change of the mixed materials, the materials are subjected to sufficient aerobic fermentation decomposition. The heat released during the decomposition process can increase the temperature of the kitchen waste itself, and part of the organic matter is decomposed, achieving the purpose of reducing the amount of kitchen waste. Through functions such as ventilation, oxygenation, and stirring, the garbage treatment equipment can ensure that the maximum temperature reaches the relevant standard requirements, can kill a large number of pathogenic bacteria and parasites in the kitchen waste heap body, and at the same time uses a deodorization system to deodorize the discharged gas, achieving the purpose of harmless treatment of kitchen waste. The products after aerobic fermentation of kitchen waste can be further processed and used for soil improvement, landscaping, organic fertilizer raw materials, etc.

[0003] In the existing kitchen waste treatment equipment and technology, the addition of microbial strains requires manual observation of the conditions inside the tank. According to the fermentation situation of the discharged fertilizer, the fermentation quality is judged manually, the microbial inoculum in the tank body is opened, and the microbial inoculum is added manually.

Since during the fermentation process, the artificial addition of inoculum, etc., will have a greater impact on the high-temperature aerobic fermentation of kitchen waste, the following problems mainly exist:

[0005] 2. The labor cost is increased because the inoculum is added manually, and it is necessary to continuously arrange personnel to observe the fermentation quality and judge the addition time and quantity of additives;

[0006] 3. It affects the quality of the output organic fertilizer. Due to the phenomenon of untimely addition, excessive addition or insufficient addition of microbial inoculum, etc., the high-temperature aerobic fermentation of kitchen waste is incomplete, and harmful substances cannot be completely reacted and eliminated, resulting in defects or non-compliance of the quality of the output organic matter.

[0007] Therefore, it is urgent to design a strain cultivation environment adjustment component and a strain cultivation device applying the component to improve the above problems. Content of the Utility Model

[0028] Embodiment:

[0029] Please refer toFigures 1 - 3 , this embodiment provides an environmental regulation component for strain cultivation, including a high-temperature aerobic fermentation bin 1. A bin support 2 is fixedly connected to the bottom of the high-temperature aerobic fermentation bin 1. An in-bin stirring device 4 is rotatably connected inside the bin support 2. A driving mechanism 5 for driving the in-bin stirring device 4 is installed on the bin support 2. An organic fertilizer discharge port 3 is provided at the bottom end of the high-temperature aerobic fermentation bin 1. A discharge electromagnetic valve is arranged at the organic fertilizer discharge port 3. A plurality of strain feeding and cultivation hoppers 6 are arranged above the high-temperature aerobic fermentation bin 1. The strain feeding and cultivation hoppers 6 are fixedly connected to the bin support 2 through fixing frames. A feed pipe 7 is fixedly connected between the discharge port at the bottom of each strain feeding and cultivation hopper 6 and the high-temperature aerobic fermentation bin 1. A feed metering valve 8 is arranged on the feed pipe 7. The strain feeding and cultivation hoppers 6 are provided in multiple numbers according to the types of microbial inoculants required during the fermentation of food waste.

[0030] Specifically, after squeezing the food waste, the solid residue is put into the high-temperature aerobic fermentation bin 1. The feed metering valve 8 on the feed pipe 7 of the corresponding strain feeding and cultivation hopper 6 is opened, so that the microbial inoculant is added into the high-temperature aerobic fermentation bin 1. After reaching the preset addition amount, the feed metering valve 8 is closed. Then, the driving mechanism 5 drives the in-bin stirring device 4 to rotate, so that the added microbial inoculant is fully stirred with the food waste solid residue, auxiliary materials, etc., in order to reach the optimal state of high-temperature aerobic fermentation. The utility model can automatically complete the addition of the microbial inoculant, has a high degree of automation, does not require on-site personnel, and has high practicability.

[0031] In this embodiment, a limit sensor is arranged inside the high-temperature aerobic fermentation bin 1. When the food waste solid residue added into the high-temperature aerobic fermentation bin 1 reaches the specified position, the limit sensor is triggered to prompt that the material addition is in place.

[0032] In this embodiment, as Figure 1 and Figure 2 shown, the driving mechanism 5 includes a driving motor 501, a driving sprocket 502, a driven sprocket 503, and a chain 504. The driving motor 501 is fixedly installed on the bin support 2. The driving sprocket 502 is fixedly connected to the output end of the driving motor 501. One end of the in-bin stirring device 4 extends outside the high-temperature aerobic fermentation bin 1 and is fixedly connected to the driven sprocket 503. The chain 504 is sleeved on the outside of the driven sprocket 503 and the driving sprocket 502. By the operation of the driving motor 501, the driving sprocket 502 is driven to rotate. The driving sprocket 502 drives the driven sprocket 503 to rotate synchronously through the chain 504.

The oxygen concentration in the high-temperature aerobic fermentation tank 1 is monitored in real time through the oxygen concentration sensor 10. When the oxygen concentration does not meet the fermentation requirement, the switch solenoid valve is controlled to automatically open for oxygen supplementation. When the oxygen concentration meets the fermentation requirement, the switch solenoid valve is controlled to automatically close.

The detection end of the temperature sensor 11 extends into the high-temperature aerobic fermentation tank 1. The temperature in the high-temperature aerobic fermentation tank 1 is monitored in real time through the temperature sensor 11. When the temperature in the high-temperature aerobic fermentation tank 1 does not meet the fermentation requirement, the heating device is controlled to work so that the heat exchange medium circulates in the heat conduction pipe 102 and conducts heat to the heat conduction plate 103 to uniformly heat the high-temperature aerobic fermentation tank 1.

Therefore, the control method and the circuit connection of the present utility model will not be explained in detail.

[0037] Working principle: During use, the solid residue after pressing the kitchen waste is put into the high-temperature aerobic fermentation tank 1. When the kitchen waste solid residue added into the high-temperature aerobic fermentation tank 1 reaches the designated position, the limit sensor is triggered, and the limit sensor generates a signal and transmits it to the controller to control the opening of the feed metering valve 8 on the feed pipe 7 of the corresponding strain addition and cultivation hopper 6, so that the microbial inoculum is added into the high-temperature aerobic fermentation tank 1. The amount of the added microbial inoculum can be measured through the feed metering valve 8. After reaching the preset addition amount, the feed metering valve 8 is closed. Then, the drive motor 501 is controlled to work to drive the driving sprocket 502 to rotate. The driving sprocket 502 drives the driven sprocket 503 to rotate synchronously through the chain 504, and the driven sprocket 503 drives the stirring device 4 in the tank to rotate, so as to realize the stirring and fermentation of the microbial inoculum and the kitchen waste solid residue. During the fermentation process, when the oxygen concentration in the high-temperature aerobic fermentation tank 1 does not meet the fermentation requirement, the switch solenoid valve is controlled to open automatically to supplement oxygen. When the temperature in the high-temperature aerobic fermentation tank 1 does not meet the fermentation requirement, the heating device is controlled to work so that the heat exchange medium circulates in the heat conduction pipe 102 and conducts heat to the heat conduction plate 103 to uniformly heat the high-temperature aerobic fermentation tank 1. After the fermentation is completed, the discharge solenoid valve is controlled to open to discharge the organic matter from the organic fertilizer discharge port 3. The online detection of the discharged organic matter can be carried out in time through the provided organic fertilizer automatic detection device, including indicators such as moisture content, pH value, organic matter, and heavy metals. When the detection indicators do not meet the standard values, the detection automatically identifies and controls the opening of the feed metering valve 8 to timely increase the addition amount of the microbial inoculum so as to meet the organic fertilizer use standard. The present utility model can automatically complete the addition of the microbial inoculum, has a high degree of automation, does not require on-site personnel, and has high practicability.
