Description

Technical Field

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

[0002] Bio-organic fertilizer refers to a type of fertilizer that has the effects of both microbial fertilizer and organic fertilizer, which is composed of specific functional microorganisms and organic materials that are mainly derived from animal and plant residues and have been harmlessly treated and decomposed. Fermentation is required during the processing of bio-organic fertilizer to decompose the complex organic matter in organic waste into simpler nutrients, thereby improving the fertilizer efficiency.

[0003] Traditional biological organic fertilizer fermentation devices will produce a large amount of water vapor during the fermentation process of organic fertilizer, which will cause the organic fertilizer to clump. The agglomeration of organic fertilizer will affect the fermentation effect of the fertilizer, making the fermentation speed of organic fertilizer inconsistent and incomplete, thereby resulting in low fermentation efficiency and qualified rate. At the same time, in traditional devices, the uneven oxygen supply makes the microbial activity uneven during the fermentation process, affecting the fermentation effect, which may lead to a decrease in the quality of the fermentation product, prolonged fermentation time, odor problems, and ultimately unstable or uneven nutritional components of the organic fertilizer. Therefore, a biological organic fertilizer fermentation device is proposed to solve the above problems. Utility Model Content

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0021] Reference Figure 1-Figure 3As shown, a biological organic fertilizer fermentation device includes a heat-insulating shell 1, a fermentation tank 2 is fixedly connected to the inner side of the heat-insulating shell 1, a heating chamber 3 is formed between the fermentation tank 2 and the heat-insulating shell 1, a plurality of evenly distributed heating plates 4 are arranged inside the heating chamber 3, the heating plates 4 are fixedly connected to the outer surface of the fermentation tank 2, the upper end of the heat-insulating shell 1 is rotatably connected to a first drive shaft 5, one end of the first drive shaft 5 is rotatably connected to a rotary joint 14, the other end of the rotary joint 14 is fixedly rotatably connected to a first gas pipe 15, and the other end of the first gas pipe 15 is fixedly connected to an exposure Air machine 16, the other end of the first drive shaft 5 passes through the insulation shell 1 and the upper end of the fermentation tank 2 and extends to the interior of the fermentation tank 2. The outer surface of the fermentation tank 2 is fixedly connected to the spiral conveying blade 6. The outer surface of the first drive shaft 5 is located at the upper end of the fermentation tank 2 and is fixedly connected to the driving gear 7. The periphery of the driving gear 7 is engaged with four evenly distributed driven gears 8. The driven gear 8 is rotatably connected to the upper end of the fermentation tank 2. The lower end of the driven gear 8 is fixedly connected to the second drive shaft 9. The outer surface of the second drive shaft 9 is fixedly connected to a number of evenly distributed crushing blades 10.

[0022] Furthermore, the outer surface of the first drive shaft 5 is located at the upper end of the insulation shell 1 and is fixedly connected to the first pulley 11. The upper end of the insulation shell 1 is located on the left side of the first drive shaft 5 and is fixedly installed with a motor 17 through a fixed seat. The output end of the motor 17 is fixedly connected to the rotating shaft 18, and the other end of the rotating shaft 18 is rotatably connected to the upper end of the insulation shell 1. The outer surface of the rotating shaft 18 is fixedly connected to the second pulley 19, and the outer surfaces of the second pulley 19 and the first pulley 11 are provided with a transmission belt 20.

[0023] Furthermore, the heating plate 4 can heat the fermentation tank 2, and the heat-insulating shell 1 can reduce heat dissipation, thereby reducing heat loss. The heating temperature of the heating plate 4 can be controlled by an external control system to ensure that the tank is at a suitable fermentation temperature.

[0024] Furthermore, the motor 17 can drive the rotating shaft 18 and the second pulley 19 to rotate. When the second pulley 19 rotates, the first pulley 11 will also rotate synchronously under the drive of the transmission belt 20, thereby driving the first drive shaft 5 to rotate, so that the spiral conveying blade 6 operates to transport the material at the bottom upward, thereby stirring the material. When the first drive shaft 5 rotates, it will drive the driving gear 7 to rotate synchronously. Since the four driven gears 8 are engaged with the driving gear 7, when the driving gear 7 rotates, the four driven gears 8 will rotate synchronously, so that the second drive shaft 9 drives the crushing blade 10 to rotate to crush the agglomerated fertilizer produced by water vapor during the fermentation process, thereby maintaining the uniformity and fluidity of the fertilizer.

[0025] Reference Figures 1-4The interior of the first drive shaft 5 is a hollow structure. An aeration pipe 12 is fixedly connected to the interior of the first drive shaft 5. A number of evenly distributed aeration nozzles 13 are fixedly connected to the outer surface of the aeration pipe 12. The end of the aeration nozzle 13 away from the aeration pipe 12 passes through the outer surface of the first drive shaft 5 and is flush with the outer surface of the first drive shaft 5.

[0026] Furthermore, the aeration nozzles 13 are evenly distributed in the gaps of the spiral conveying blades 6, and the oxygen is transported to the inside of the aeration pipe 12 through the first air pipe 15 by the aerator 16. The oxygen transported to the inside of the aeration pipe 12 will be ejected through the aeration nozzles 13. Combined with the stirring effect of the spiral conveying blades 6, the oxygen can be in more uniform contact with the material inside the tank body, ensuring that the organic fertilizer in the entire fermentation tank 2 is adequately supplied with oxygen, which can promote the activity of microorganisms and the stability of the fermentation process, and increase the fermentation rate.

[0027] Furthermore, a feed hopper 21 is fixedly connected to the outer surface of the heat-insulating shell 1, and the feed hopper 21 is communicated with the interior of the fermentation tank 2. A sealing cover 22 is movably connected to the upper end of the feed hopper 21. The sealing cover 22 can prevent external impurities from entering the interior of the fermentation tank 2 during the fermentation process, while avoiding the leakage of odor during the fermentation process, thereby keeping the working environment clean and comfortable.

[0028] Furthermore, a discharge pipe 23 is fixedly connected to the lower end of the heat-insulating shell 1 , and the discharge pipe 23 is communicated with the bottom end of the fermentation tank 2 . A discharge valve is provided on the discharge pipe 23 .

[0029] Furthermore, the upper end of the insulation shell 1 is fixedly connected to a second gas pipe 24, and the second gas pipe 24 is connected to the upper end of the fermentation tank 2. The end of the second gas pipe 24 away from the insulation shell 1 is fixedly connected to a gas cleaning box 25, and the exhaust port of the gas cleaning box 25 is fixedly connected to an exhaust pipe 26. The interior of the gas cleaning box 25 is provided with an activated carbon net and a fan. The exhaust gas generated during the fermentation process can be sucked into the interior of the gas cleaning box 25 through the fan, and then the odor and harmful substances in these gases are adsorbed by the activated carbon net and then discharged through the exhaust pipe 26, which can reduce the pollution of the waste gas to the environment.

[0030] Working principle: When in use, open the sealing cover 22, inject the material into the fermentation tank 2 through the feed hopper 21, then cover the sealing cover 22 and start the motor 17 to drive the rotating shaft 18 and the second pulley 19 to rotate. When the second pulley 19 rotates, the first pulley 11 will also rotate synchronously under the rotation of the transmission belt 20, thereby driving the first driving shaft 5 to rotate, so that the spiral conveying blade 6 runs to transport the material at the bottom of the fermentation tank 2 upward, thereby stirring the material. When the first driving shaft 5 rotates, it will drive the driving gear 7 to rotate synchronously. Since the four driven gears 8 are engaged with the driving gear 7, when the driving gear 7 rotates, the four driven gears 8 The two shafts 14 and 15 will rotate synchronously, so that the second drive shaft 9 drives the crushing blade 10 to rotate to break up the agglomerated fertilizer produced by water vapor during the fermentation process, thereby maintaining the uniformity and fluidity of the fertilizer. During the fermentation process, the aerator 16 will continuously transport oxygen to the inside of the aeration pipe 12 through the first air pipe 15. The oxygen transported to the inside of the aeration pipe 12 will be ejected through the aeration nozzle 13. Combined with the stirring action of the spiral conveying blade 6, the oxygen can be more evenly contacted with the material inside the tank body, ensuring that the organic fertilizer in the entire fermentation tank 2 is adequately supplied with oxygen, which can promote the activity of microorganisms and the stability of the fermentation process, thereby increasing the fermentation rate.
