Powder conveying
Thread Content
There is a material in our factory that needs to be transported to the reactor at 5T/h. The material is dried by a centrifuge (the oil content is about 2-5%). I would like to ask which pneumatic conveying equipment is better.
It has no granularity or physical properties, so how can I recommend it!
Pneumatic conveying is an important link in clean production. It is a process that uses sealed conveying pipes to replace traditional mechanical conveying materials. It has the following characteristics: ·Flexible layout and long conveying distance ； Leak-free transportation and no secondary pollution ； Energy saving and efficient ； Centralized transportation and recycling ； It has more advantages in special powder transportation. !
You can place the centrifuge on one floor above the reaction kettle. After the centrifuge has centrifuged the material and dried it, use a scraper to scrape the material into a conical storage tank. Open a 200-300mm hole under the storage tank, and then use a propeller to push it into the reaction kettle. The specific material and size will depend on the nature and quantity of the material before deciding. You can do a small test first to see.
A screw conveyor can be used for feeding. The entire process is heat and pressure resistant and is fully enclosed.
The information you gave is too general. You should provide the specific properties of the materials, the distance of transportation, etc. And also, whether you use intermittent transportation or continuous transportation. Based on the information you gave above, I feel that negative pressure transportation is still worthy of recommendation.
Replenish: This material contains oil, which is not conducive to transportation. It is recommended to install an air hammer or vibration motor on the transportation pipeline!
I think it is not feasible to transport oily or water-containing materials by pneumatic transport. The suggestions on the 4th and 5th floors are better and should not be blocked.
Dry nitrogen can be used for transportation, but the cost is higher.
In this working condition, a screw feeder can be used to add materials into the reaction kettle. When the materials enter the screw, they can be lifted by high-level gravity flow or by lifting methods such as bucket elevators and belt conveyors. If you definitely want to use pneumatic conveying, you can consider "air flow dense phase conveying", which uses very little air.
If the sealing requirements are not high, the conveying distance is not far, and the specific gravity of the material is relatively large, it is not recommended to use pneumatic conveying. Pneumatic conveying only has advantages in conveying bulk materials, low density, and long conveying distances.
