Description

Technical Field

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

[0002] In the production process of humic acid fertilizer, fermentation is a key step, which directly affects the quality and effect of the final product. Appropriate ventilation volume during the fermentation process can ensure that microorganisms obtain sufficient oxygen for aerobic fermentation, thereby accelerating the decomposition rate, improving the tolerance and metabolic capacity of microorganisms to VFAs, and reducing the toxic effects of volatile fatty acids generated during fermentation.

[0003] At the same time, waste gas is generated during the aerobic fermentation of humic acid fertilizer, and the waste gas needs to be collected and treated. At present, the exhaust outlet of the waste gas and the intake port of oxygen on the fermentation device are set at different positions. To improve the uniformity of oxygen distribution, multiple groups of intake ports for oxygen are distributed. At the same time, to prevent impurities from entering the exhaust outlet during fermentation stirring, a protective net is installed at the exhaust outlet, and a cleaning mechanism needs to be set to clean it regularly.

[0004] Due to the complexity of the above structure, this solution provides a fermentation device for the production of humic acid fertilizer, which combines the intake and exhaust structures, reduces the number of intake ports and realizes uniform gas distribution without additional power sources, and can also complete the cleaning of the protective net. Content of the Utility Model

[0005] The utility model aims to solve at least the problem that the intake structure and the exhaust structure in the prior art are independent and separated from each other and cannot interact.

[0006] This solution provides a fermentation device for the production of humic acid fertilizer, which is achieved by the following specific technical means: including a fermentation tank with an internal stirrer, an intake cylinder is fixedly penetrated through the top wall of the fermentation tank, an exhaust pipe is fixedly penetrated through the top wall of the intake cylinder, the bottom end of the exhaust pipe extends out from the bottom opening of the intake cylinder, the outer diameter of the exhaust pipe is smaller than the inner diameter of the intake cylinder, and an intake hood is fixedly sleeved at the bottom end of the exhaust pipe, and a protective net is fixed inside the bottom opening of the intake hood. At the same time, an impeller is rotatably sleeved at the top of the intake hood, and the impeller is rotatably sleeved at the bottom opening of the intake cylinder. When injecting oxygen from the intake cylinder into the fermentation tank, when the oxygen flows out from the impeller, it drives the impeller to rotate, centrifugally spraying the oxygen around, and at the same time, there is a cleaning part at the bottom side of the impeller, and the cleaning part brushes and cleans while fitting the protective net.

[0007] Preferred Technical Solution 1: The air outlet pipe is composed of an air outlet fixed cylinder penetrating and fixed on the top wall of the air inlet cylinder and an air outlet movable cylinder slidably connected to the bottom opening of the air outlet fixed cylinder. The bottom end of the air outlet movable cylinder extends out from the bottom opening of the air inlet cylinder, and an air inlet cover is fixed to the bottom end of the air outlet movable cylinder. A spring is connected between the top wall of the air inlet cover and the inner wall of the air inlet cylinder. At the same time, the impeller is slidably connected to the air inlet cylinder.

[0008] Preferred Technical Solution 2: The top end of the air inlet cylinder is fixedly connected to the gas adsorption processor for adsorption and deodorization treatment.

[0009] Preferred Technical Solution 3: A gas supply device is externally connected to the air inlet cylinder through a pipeline.

[0010] Preferred Technical Solution 4: A protective cover is fixedly sleeved on the middle and lower part of the air inlet cylinder. The protective cover has an opening facing downward, and the inner diameter of the protective cover is equal to the outer diameter of the impeller. When the air inlet stops and the air inlet cover moves upward, the impeller completely slides into the protective cover for storage.

[0011] Preferred Technical Solution 5: The diameter of the air inlet cover is larger than the inner diameter of the air inlet cylinder.

[0012] Adopting the above structure enables this solution to have the following beneficial effects:

[0013] 1. By combining the air inlet cylinder and the air outlet pipe, and using the impeller and the cleaning part, it is possible to reduce the number of air inlets and achieve uniform air distribution without setting up an additional power source, and at the same time, it can also complete the cleaning function of the protective net;

[0014] 2. While collecting the waste gas, the air inlet cover can also block the air inlet cylinder to prevent the waste gas from entering the air inlet cylinder;

[0015] 3. The setting of the protective cover can protect and store the upward-moving impeller after the air inlet stops. Description of the Drawings

At the same time, an outlet pipe 3 is fixedly penetrated through the top wall of the intake cylinder 2, the top end of the outlet pipe 3 is fixedly connected to a gas adsorption processor 8 to perform adsorption and deodorization treatment on the discharged waste gas. The bottom end of the outlet pipe 3 extends out from the bottom opening of the intake cylinder 2, the outer diameter of the outlet pipe 3 is smaller than the inner diameter of the intake cylinder 2, and an intake hood 4 is fixedly sleeved at the bottom end of the outlet pipe 3, and a protective net 41 is fixedly arranged inside the bottom opening of the intake hood 4. At the same time, an impeller 5 is rotatably sleeved at the top of the intake hood 4, and the impeller 5 is rotatably sleeved at the bottom opening of the intake cylinder 2. When injecting oxygen from the intake cylinder 2 into the fermentation tank 1, when the oxygen flows out from the impeller 5, it drives the impeller 5 to rotate, centrifugally spraying the oxygen in all directions to achieve rapid gas uniformity. At the same time, a cleaning part 7 is fixedly connected to the bottom side of the impeller 5 through a vertical rod 6, and the cleaning part 7 brushes and cleans the protective net 41 when the impeller 5 rotates while being attached to the protective net 41;

[0025] A controller 12 is arranged on the fermentation tank 1, and the controller 12 is electrically connected to the air supply device and the stirrer 11 for controlling the air supply state of the air supply device and the stirring state of the stirrer 11.

[0026] Please refer to Figures 2 - 5, a fermentation device for the production of humic acid fertilizer.

The bottom end of the air outlet movable cylinder 32 extends out from the bottom opening of the air inlet cylinder 2, and the air inlet hood 4 is fixedly sleeved on the bottom end of the air outlet movable cylinder 32. A spring 33 is connected between the top wall of the air inlet hood 4 and the convex ring 21 fixed inside the air inlet cylinder 2. The spring 33 is always in a stretched state. At the same time, the impeller 5 is slidably connected to the air inlet cylinder 2. The diameter of the air inlet hood 4 is larger than the inner diameter of the air inlet cylinder 2. When oxygen is not supplied, the air inlet hood 4 moves upward due to the rebound of the spring 33 to block the air inlet cylinder 2, preventing waste gas from entering the air inlet cylinder 2 from the bottom opening. At this time, the overall length of the air outlet pipe 3 is shortened, and the impeller 5 is also driven to move upward along the air inlet cylinder 2. When oxygen is supplied, the gas pushes the air inlet hood 4 downward, causing the spring 33 to be stretched, and the impeller 5 also moves downward.
