Description

Technical Field

[0001] The invention relates to the technical field of organic bacterial fertilizers, and in particular to a method and a device for preparing aerobic fermentation organic bacterial fertilizers. Background Art

[0002] In recent years, the rapid development of large-scale livestock and poultry farming in my country has brought about tremendous pressure on breeding companies due to the organic solid waste caused by centralized breeding. Livestock and poultry farming waste is a valuable resource rich in organic matter and plant nutrients. Through the aerobic fermentation technology of organic fertilizer, the reduction, harmlessness and resource utilization of livestock and poultry waste can be achieved, which can not only reduce the pollution of waste to the environment, but also turn waste into treasure. In order to avoid the secondary pollution of the atmospheric environment by odorous gases in the traditional open aerobic fermentation process, a fully enclosed fermentation tank is used in the aerobic fermentation of organic fertilizer. The aerobic fermentation process of organic fertilizer is a process in which various fermentation bacteria degrade large molecular structures into small molecular structures and transform them into stable humus. The traditional open aerobic fermentation cycle is usually about 45 to 60 days, while the fermentation cycle of a fully enclosed fermentation tank can be reduced to less than 30 days. Fully enclosed fermentation is to place the entire fermentation process in a fully enclosed fermentation tank, and a large amount of oxygen needs to be provided. Therefore, all fully enclosed fermentation-related equipment must use pressure-resistant equipment.

[0003] The current equipment has a single function in the process of fermenting materials. It can enable natural fermentation. However, since the materials are stationary inside the fermentation barrel, the contact between the materials and oxygen is insufficient, resulting in poor fermentation effect, which in turn leads to reduced fermentation efficiency. Moreover, since the fermentation speed of the materials is different at different temperatures, and the current equipment cannot adjust the temperature, the fermentation efficiency is reduced. Therefore, there is an urgent need for a method and device for preparing aerobic fermentation organic fertilizer to improve the above problems. Summary of the Invention

[0050] The implementation principle of this embodiment is:

[0051] The preparation method and device of the aerobic fermentation organic fertilizer are provided with a feed port 8. When using the device, the staff transports the material to the inside of the feed port 8 through the feeding device, so that the material can enter the inside of the fermentation barrel 1. After the material is added, the staff seals the device. Then, the staff starts the motor 4. The rotation of the motor 4 can drive the driving wheel 5 to rotate. The rotation of the driving wheel 5 can drive the belt to rotate. The rotation of the belt can drive the driven wheel 16 to rotate. The rotation of the driven wheel 16 can drive the connecting shaft 11 to rotate. The rotation of the connecting shaft 11 can drive the spiral blade 14 to rotate. When the spiral blade 14 rotates, it can lift the material at the bottom by cooperating with the sleeve 13, and when the connecting shaft 11 rotates It can drive the stirring rod 15 to rotate, thereby stirring the material, thereby making the material flow, thereby making the material and oxygen mixed more fully, thereby improving the fermentation efficiency. In this process, the staff connects with the external air supply equipment through the rotary joint 17, thereby making the oxygen enter the interior of the rotary joint 17, and the oxygen inside the rotating head can enter the interior of the connecting shaft 11 through the through groove 18. Through the air hole 19 and the guide groove 20, the oxygen can enter the interior of the stirring rod 15 and the spiral blade 14, and then the oxygen can be ejected through the aeration hole 21, thereby making the material and oxygen mixed more fully, thereby improving the fermentation effect of the material, thereby improving the fermentation efficiency.

[0052] When the connecting shaft 11 rotates, the connecting shaft 11 can drive the first gear 26 to rotate, the rotation of the first gear 26 can drive the second gear 25 to rotate, and the rotation of the second gear 25 can drive the reciprocating screw to rotate. Due to the design of the telescopic rod 31, the threaded sleeve 23 can be prevented from rotating, and the threaded sleeve 23 can be driven to move up and down during the rotation of the reciprocating screw, so that the threaded sleeve 23 can drive the temperature detection probe 24 to move up and down. When the second gear 25 rotates, the second gear 25 contacts the ring gear 27, which can make the second gear 25 perform a circular motion. The movement of the second gear 25 can It can drive the connecting frame 28 to rotate. Since the connecting frame 28 is rotatably connected to the first gear 26 and the second gear 25, the connecting frame 28 can be rotated, which can drive the slider 29 to rotate. Since the slider 29 is slidably connected to the slide groove 36, the slider 29 can be moved, and the temperature detection probe 24 can be moved in a circular motion, so that the temperature of various places inside the fermentation barrel 1 can be detected. When the detection is completed, the temperature inside the fermentation barrel 1 can be controlled by the heating tube 33 and the cooling tube 34, so that the fermentation can always be kept at a more suitable temperature, thereby improving the fermentation efficiency.
