Technical Field

[0001] The utility model belongs to the field of organic fertilizer production equipment, and in particular relates to biological organic fertilizer fermentation and drying equipment. Background Art

[0002] Bio-organic fertilizer is a fertilizer obtained by composting and fermenting biological raw materials. The raw materials of bio-organic fertilizer will produce a certain amount of moisture during the fermentation process. In order to facilitate storage and transportation, the fermented product needs to be dried after fermentation. In the traditional processing flow, the fermentation and drying steps are often carried out in sequence using different equipment. Among them, the equipment commonly used for drying organic fertilizer is a hot air dryer. In order to improve production convenience, some existing organic fertilizer production equipment has achieved the integrated function of fermentation and drying through functional aggregation. The integrated means include adding a drying component to the discharge part of the fermentation equipment, or continuously stirring the fermented product in a fermentation equipment with a heating function to achieve a drying effect. The former has a short and fixed heating time and cannot ensure the drying effect. The latter has the defects of uneven drying and long drying time due to the large accumulation of fermented materials. In response to the above problems, the utility model proposes a bio-organic fertilizer fermentation and drying equipment. Utility Model Content

[0022] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1-4 As shown, the biological organic fertilizer fermentation and drying equipment of this embodiment includes a heating tank 1 and a frame thereof. The electric heating tube of the heating tank 1 is embedded in the side wall (not shown in the figure). A barrel for holding fermented material is provided in the heating tank 1. A gap is provided between the barrel and the heating tank 1 and the barrel can be ventilated all around. The heating tank 1 is also equipped with a hot air circulation mechanism, which is used to stir the fermented material and continuously pump the gas outside the barrel into the fermented material.

[0025] When using the device, the raw material of biological organic fertilizer can be placed in a barrel for fermentation. During the fermentation process, the driving member corresponding to the central tube 4 can be turned to rotate the integral body formed by the central tube 4 and the branch pipe 5, so as to achieve the effect of stirring the biological organic fertilizer to ferment it fully. After the fermentation is completed, the heating tank 1 is turned on, and the material and gas inside are heated at the same time. After the hot air circulation mechanism is turned on, on the one hand, the material in the barrel is continuously heated, and the water evaporates continuously, and is converted into high-temperature gas, which is mixed with the original high-temperature gas in the heating tank 1 and surrounded by the outside of the barrel. On the other hand, the hot air circulation mechanism continuously stirs the fermented material, and the high-temperature gas outside the barrel is pumped into the fermented material. The injected high-temperature gas overflows from the gap between the fermented material and then re-enters the cycle. In this process, the effect of continuous stirring and irregular overflow of the gas can improve the porosity of the fermented material. The high-temperature airflow can also fully contact the fermented material in different directions, and the uniformity of the fermented material being heated is greatly improved, thereby effectively improving the drying efficiency of the fermented material.

[0026] Preferably, the material barrel includes a base 2 and a mesh tube 3 arranged on the base 2. The base 2 is a truncated cone structure and a support block is provided on the outside. The fermentation liquid produced during the fermentation process will settle downward. The truncated cone-shaped base 2 can prevent the fermentation liquid from overflowing, so that the effective ingredients therein can fully participate in the fermentation process and will not interfere with the gas circulation due to accumulation near the air inlet of the hot air circulation mechanism.

[0027] Preferably, the hot air circulation mechanism includes a central tube 4 that is vertically arranged in the barrel and can rotate. A number of evenly distributed exhaust components are provided on the outside of the central tube 4. The exhaust components are used to output airflow while stirring the fermented material. The exhaust position changes continuously with the stirred part, so that the hot air flow can be distributed over a large range and overflow in multiple directions.

[0028] Preferably, the exhaust assembly includes a branch pipe 5 connected to the central pipe 4 and a surrounding extension frame 6 provided on the outside of the outlet end of the branch pipe 5. The lengths of the exhaust assemblies are the same, and the lengths of the branch pipes 5 are different. The different lengths of the branch pipes 5 result in different radial depths of the hot air flow injection point, which can further improve the uniformity of the distribution of the hot air flow in the fermentation product.

[0029] Preferably, the branch pipe 5 has an inclined structure and the air outlet is located at the lower end of the incline.

[0030] Preferably, a shielding piece 8 for shielding materials is provided at the exhaust port of the branch pipe 5. The shielding pieces 8 include several shielding pieces 8 distributed in a circular array. The branch pipe 5 is provided with a shielding net 7 for supporting the shielding piece 8. The air outlet is tilted downward. The combination of the shielding piece 8 and the shielding net 7 can prevent the fermented material on the outside from entering the air outlet of the branch pipe 5 and affecting the air outlet. However, the air flow can pass through the shielding net 7 to break through the shielding piece 8 and be output, which is beneficial to improving the stability of the equipment operation and function.

[0031] Preferably, the hot air circulation mechanism also includes an outlet pipe 11 for conducting the airflow outside the barrel. The outlet pipe 11 is connected to the central pipe 4 through a circulation fan. The bottom end of the central pipe 4 is closed, and the top end of the central pipe 4 passes through the top cover of the heating tank 1 and a corresponding driving member is provided on the top cover. The circulation fan is connected to the central pipe 4 through an air inlet pipe 12, and the central pipe 4 is rotatably connected to the air inlet pipe 12. In this embodiment, the air inlet of the outlet pipe 11 extends to the gap between the heating tank 1 and the mesh cylinder 3, and is located within the upper third of the height of the mesh cylinder 3. Even if a small amount of liquid produced by fermentation overflows the mesh cylinder 3 due to squeezing between the solids during the stirring process, the liquid is not easy to enter the outlet pipe 11, so that the airflow can circulate stably.

[0032] Preferably, the driving member corresponding to the central tube 4 includes a motor and a gear 13 for transmission.

[0033] Preferably, the top cover of the heating tank 1 includes a detachable fixed cover 9 and a side flip cover 10 provided on the fixed cover 9. The central tube 4 and its corresponding driving member and circulating fan are located on the fixed cover 9. After the material barrel, top cover and hot air circulation mechanism are installed in place, the side flip cover 10 is opened to add materials, thereby avoiding the problem of first adding the fermentation material and then being inconvenient to insert the exhaust component.

[0034] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
