Description

Technical Field

[0001] This utility model relates to a stirring device, and more particularly to an aerobic fermentation stirring device. Background Technology

[0002] In organic waste resource utilization and harmless treatment projects, organic waste, after sorting, crushing, and dehydration, needs to be decomposed at high temperatures in an aerobic fermentation tank by aerobic microorganisms to produce organic fertilizer. The main utilization pathways for the fermented product include: farmland use, forest land use, landscaping use, land remediation of abandoned mines, and landfill cover soil. Because the organic waste entering the aerobic fermentation tank is generally slag-like, with high water content and viscosity, it easily clumps when mixed with microorganisms, leading to microbial hypoxia and loss of activity, thus affecting the aerobic decomposition process. Therefore, stirring is necessary to solve these problems. Furthermore, to achieve high-temperature aerobic decomposition, a heating device is installed at the bottom of the tank to continuously heat the bottom material. Existing high-efficiency aerobic fermentation stirring equipment is difficult to recycle the pollutants generated during organic matter decomposition, easily causing environmental pollution and affecting people's lives. Therefore, it is necessary to develop a high-efficiency aerobic fermentation stirring equipment and recycling system for organic waste. Utility Model Content

[0003] This invention provides an aerobic fermentation stirring device to overcome the shortcomings of existing aerobic fermentation stirring equipment in terms of difficulty in recycling pollutants generated from the decomposition of organic matter.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses an aerobic fermentation stirring device, including a frame. A planetary reducer is fixedly installed on the left side of the frame, and a motor is fixedly connected to the input shaft end of the planetary reducer. A mechanical seal and a ribbon mixer are installed inside the frame. The ribbon mixer is a combination of a slanted paddle and a spiral. The frame and the mechanical seal are fixedly installed on the flange of the tank by bolts. A partition is provided inside the tank. A heating device, a filter screen, and a rice husk layer are respectively provided at the bottom of the inner cavity of the tank. A spiral discharge machine is installed at the discharge port on the right side of the tank and is connected to the feed port of the spiral conveyor by a clamp. A granulator and a silo are provided below the spiral conveyor.

[0006] Furthermore, the ribbon mixer includes a mixing shaft, on which an agitator is mounted by bolts.

[0007] Furthermore, one end of the stirring shaft passes through a mechanical seal and is fixedly connected to the output shaft end of the planetary reducer, while the other end is fixed to the right side of the tank.

[0008] Furthermore, a blower is provided on the upper right side of the tank to supply air into the tank.

[0009] Furthermore, the blower is connected to the inner pipe of the rice husk layer and supplies oxygen into the inner cavity of the tank.

[0010] Furthermore, the partition is arranged in seven layers.

[0011] The beneficial effects achieved by this utility model are as follows: By installing a ribbon mixer with a combination of inclined paddle and spiral types inside the tank, circumferential and axial flows are generated in the inner cavity of the tank as the mixing action is performed. The material and aerobic microorganisms come into full contact under the action of mixing, which allows the heated material to disperse and diffuse rapidly. A spiral pushing flow is generated towards the discharge port of the tank, which makes the material move slowly towards the discharge port. From the time the material is fed in, it enters a complex fluid environment that combines multi-stage internal circulation flow and spiral pushing flow. This allows the organic waste to come into full contact with aerobic microorganisms, and the heat from the bottom of the aerobic fermentation tank acting on the material is evenly and rapidly dispersed and diffused. This enables the organic waste to undergo high-temperature aerobic decomposition, which greatly improves the aerobic fermentation efficiency. At the same time, it is also equipped with supporting facilities such as a spiral conveyor and a granulator, which can directly transform the fermented product without transfer, thus achieving the goal of resource utilization and reduction of organic waste.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example 1

[0017] like Figure 1As shown, an aerobic fermentation stirring device includes a frame 3. A planetary reducer 2 is fixedly installed on the left side of the frame 3. A motor 1 is fixedly connected to the input shaft of the planetary reducer 2. A mechanical seal 4 and a ribbon mixer 5 are installed inside the frame 3. The ribbon mixer 5 is a combination of a slanted paddle and a spiral type. The frame 3 and the mechanical seal 4 are fixedly installed on the flange of the tank body 6 by bolts. One end of the stirring shaft 11 passes through the mechanical seal 4 and is fixedly connected to the output shaft of the planetary reducer 2. The other end is fixed to the right side of the tank body 6. A partition 10 is provided inside the tank body 6. The bottom of the cavity is equipped with a heating device 7, a rice husk layer 9, and a filter screen 8. A blower 13 is located on the upper right side of the tank 6 to supply air into the tank 6. The blower 13 is connected to the inner pipe of the rice husk layer 9 and supplies oxygen into the inner cavity of the tank 6. The screw conveyor 14 is installed at the discharge port on the right side of the tank 6 and is connected to the feed port of the screw conveyor 15 by a clamp. A granulator 16 and a hopper are located below the screw conveyor 15. The screw ribbon mixer 5 includes a mixing shaft 11, and the agitator 12 is bolted to the mixing shaft 11. The partition 10 is arranged in seven layers.

[0018] Working principle: The mixing and stirring equipment is installed inside the aerobic fermentation tank to stir the materials. After being refined by the ribbon mixer 5, the materials enter the tank. The ribbon mixer 5 is installed inside the tank body 6. As the ribbon mixer 5 stirs, the blower 13 delivers oxygen into the tank, generating an upward airflow inside the tank body 6. The materials inside the tank body 6 come into full contact with the aerobic microorganisms under the action of stirring, and the heated materials are quickly dispersed and diffused, thus allowing the organic waste to undergo thorough high-temperature treatment. The aerobic decomposition reaction generates a rightward pushing flow, causing the material to gradually move towards the discharge port of the tank 6 through the gap in the upper part of the baffle 10. Starting from the feed, the material enters a complex fluid environment that combines multi-stage internal circulation flow and spiral pushing flow. During the stirring process, the material will be dehydrated step by step. The liquid enters the discharge port through the bottom filter screen 8 and rice husk layer 9 of the tank 6 and is discharged. The generated powdery solid enters the granulator 16 through the screw conveyor 15. Finally, the fertilizer formed after exiting the granulator 16 is stored in the silo.
