Biological fermentation aeration fan

High pressure aeration vortex fanIt is a new type of power air source equipment with sufficient wind pressure, large air volume, low noise, and long service life; Its advantages are: 1. Strong and uniform aeration, capable of delivering a large amount of oxygen-containing air to the materials that require aeration; 2. Due to the abundant oxygen in the material, active microorganisms are present, and the rapid inhibition of anaerobic microbial growth accelerates anaerobic microbial death; 3. Due to the activity of microorganisms, the material undergoes sufficient fermentation, resulting in a good fermentation effect, high efficiency, and no waste of materials.

Aeration vortex fanAdopting brand new molds and aluminum shells, introducing assembly lines and testing tools, strict control, high reliability, low maintenance, and long service life. In the process of work, the efficiency of work has been improved, maintenance costs have been reduced, and energy consumption during shutdown and start-up has been reduced. Overall reduction reduces waste of resources.

Biological fermentation aeration fanto configure:
1. Shell material: The high-pressure fan is made of * degree die cast aluminum, which is the same aluminum material as the Mercedes Benz wheel hub. Compared to ordinary aluminum alloy, die cast aluminum is stronger and has a lighter weight effect compared to iron shell fans.

2. Motor performance: The high-voltage fan adopts a wide frequency and voltage motor, which is included in single-phase 110V/230V industrial three-phase: 220/380/415/660V, etc. The motor frequency can be adjusted from 45-75HZ, with an IP55 protection level and F-class insulation level. Its advantages are technology that domestic motors cannot achieve, and it is highly favored by customers at home and abroad;

3. Fan oil seal: The fan adopts German MERKEL oil seal, and the German MERKEL material uses fluororubber that can withstand temperatures from -25 ℃ to 300 ℃. Compared to the general oil seal, its lip temperature is 20-50 ℃ higher than the working medium temperature during operation, making it more stable in performance, maintenance free, and has a longer lifespan;

4. Fan bearings: The core components of the fan are made of German SKF and Japanese NSK brand bearings, which can withstand 350 degrees Celsius and 4000 revolutions per minute. For domestically produced Luo axis and Japanese bearings, the performance is stable, the noise is low, maintenance is free, and the service life is longer, which can ensure that the fan runs longer.

Biological fermentation aeration fanJob characteristics:

1. The oxygenation and aeration high-pressure blower is a classic work of our company, which changes the history of iron shell centrifugal fans in China;
2. Adopting high-strength aluminum alloy high-pressure die-casting body, it runs for a long time without overheating;
3. Smooth inner wall, flawless exterior, and lower operating noise;
4. Adopting a wideband variable frequency motor, suitable for frequency conversion between 20-80 Hz, more energy-efficient and environmentally friendly;
5. Using the manufacturing process of Siemens fan motors from Germany, we provide you with the configuration of high-pressure blowers;
6. Using exclusive Japanese NSK/SKF bearings, with superior rigidity and more suitable for long-term non-stop operation, one machine can be used on top of two domestically produced machines;
7. The blade design with a better angle allows us to have a larger air volume, higher air pressure, and twice the lifespan of domestic blowers.
8. Humanized independent fan blade connection plate allows you to avoid direct damage to the bearings even when extracting waste directly;
9. Adopting German air regenerative technology, it can operate smoothly even when the air is compressed, eliminating the situation of low air volume and pressure during the operation of high-pressure blowers;
10. The air inlet silencing cotton design makes our fan run quieter!

aeration blowerUsage requirements:
1. The fan may generate high temperatures during use, so avoid touching the casing to prevent burns.

2. The load current of the motor will vary with the air pressure used by the fan. When wiring, an overload protection switch suitable for the model should be installed and used at the rated full load current to avoid motor burnout.

3. The applicable range of continuous operation of the fan should not exceed the applicable range. If it is necessary to approach the closed pressure during use, a pressure relief valve should be installed in the pipeline. When the pipeline is closed, the pressure relief valve will automatically open to regulate the air inlet and outlet to ensure the service life of the fan. If the fan is operated under the closed pipeline, the temperature will rise sharply. At this time, continuous operation should be avoided, otherwise deformation or damage may occur. When the air used is intermittent, the air valve switching mode should be used for operation.

4. Hard objects, dust bag particles, fibers, and water droplets should be removed before entering the fan, and can be treated with dust bags. If a filter is installed in the pipeline, to avoid pressure reduction losses, please use a large area filter and regularly clean the pollutants in the filter.

5. Regularly clean the inside and outside of the fan to remove surface dust. If a large amount of dust accumulates, the heat dissipation effect will deteriorate, which may cause temperature rise, reduced air volume, increased vibration, and ultimately lead to malfunction.

6. Bearings, oil seals, and mufflers are consumables and therefore have a certain lifespan, requiring regular replacement. At the same time, blades, shells, metal mesh, etc. must also be replaced regularly according to the usage environment (mainly corrosive air flow, gas-liquid mixture, etc.).

7. If the operation is not smooth or there is abnormal noise during use, please turn off the power for maintenance or call.

With the continuous development of China's sewage treatment industry, the increasing number of dehydrated sludge from sewage treatment plants has gradually become a stubborn problem in urban management. Traditional landfill or disposal methods can no longer meet current needs, and technologies for harmless, reduced, and resourceful sludge have developed accordingly. The aerobic composting technology for sludge, as a sludge disposal technology suitable for China's national conditions, is being promoted and developed. The aerobic aeration process is a major component of the sludge aerobic composting process, and the rational selection of the aeration high-pressure fan will have a significant impact on the technical and economic feasibility of the entire project.
