Technical Field

[0001] The utility model relates to the technical field of fertilizer fermentation, in particular to a composite microbial fertilizer fermentation production device. Background Art

[0002] Microorganism fermentation engineering is an important part of bioengineering. The application fields of bioengineering are very wide, including agriculture, industry, medicine, pharmacology, energy, environmental protection, metallurgy, chemical raw materials, etc. It will have a huge impact on the politics, economy, military and life of human society, and provide a bright prospect for solving the problems of resources, environment and human health faced by the world.

[0003] During the microbial fermentation process, it is generally necessary to heat the fertilizer, but the traditional heating device is generally electric heating, that is, a heating wire is set inside the fermentation box. Since these electric heaters are generally fixed, it is difficult to make full contact with the fertilizer, resulting in the need to improve the uniformity of heating. In addition, after the fermentation is completed, after the fermented fertilizer is discharged, some solid fertilizer will adhere to the inner wall of the box. In the existing method, a scraper is generally used to remove it. However, when the scraper is used to remove it, it is easy to damage the inner wall of the box, and the service life of the scraper is relatively short. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3A composite microbial fertilizer fermentation production device comprises a shell 1, a feed port 4 is arranged at the inner top of the shell 1, a discharge port 3 is arranged at the inner bottom of the shell 1, a sealing cover 8 is installed at the lower end of the discharge port 3, and a plurality of supporting legs 2 are installed at the lower end of the shell 1;

[0020] The stirring mechanism includes a motor 5 mounted on the upper end of the housing 1. The motor 5 is a servo motor capable of changing the direction of rotation. The output shaft of the motor 5 extends into the housing 1. The output shaft of the motor 5 is fixedly connected to a rotating shaft 7. A plurality of stirring rods 9 are fixedly connected to the outer side of the rotating shaft 7 at equal intervals.

[0021] The heating mechanism includes a spiral induction coil 10 embedded in the inner wall of the housing 1. The material of the plurality of stirring rods 9 is iron alloy. When the spiral induction coil 10 is started, the plurality of stirring rods 9 made of metal material are inductively heated;

[0022] It also includes a cleaning mechanism, which is used to clean the inner wall of the shell 1. The cleaning mechanism includes a hollow ring 12 fixedly connected to the top of the shell 1, and a plurality of inclined exhaust ports 13 are provided at the inner bottom of the hollow ring 12. A high-pressure air pump 6 is installed at the upper end of the shell 1, and the air outlet end of the high-pressure air pump 6 is connected to a connecting pipe 11, and the other end of the connecting pipe 11 is connected to the inside of the hollow ring 12, and the plurality of inclined exhaust ports 13 are all facing the inner wall of the shell 1.

[0023] In the utility model, when in use, the fermented material is put in from the feed port 4, and then the induction coil 10 is started, and the motor 5 and the rotating shaft 7 are started at the same time. After the induction coil 10 is started, the metal stirring rod 9 is heated. After the motor 5 is started, the rotating shaft 7 is driven to rotate. The rotation of the rotating shaft 7 can make multiple stirring rods 9 stir. Since the multiple stirring rods 9 have a certain temperature, they are equivalent to a heating source at this time. Therefore, their rotation can make full contact with the fermented material to achieve the purpose of uniform heating, and effectively ensure the uniformity of heating;

[0024] After the subsequent fertilizer has completed fermentation, the discharge port 3 is opened. After the discharge port 3 is opened, the fermented fertilizer is discharged. At this time, the high-pressure air pump 6 is started. After the high-pressure air pump 6 is started, the high-pressure gas generated will enter the hollow ring 12 and finally be discharged from multiple inclined exhaust ports 13. The gas discharged from the multiple inclined exhaust ports 13 can quickly blow off the fertilizer adhered to the inner wall of the shell 1, and finally be discharged from the discharge port 3, thereby cleaning the inner wall of the shell 1.
