How to feed solid powder materials into a reaction vessel
Thread Content
As the title suggests, powder materials are fed into the reaction vessels in large quantities – several tons each time. The powder is packaged in ton bags, and it is considered useful to use a lift to raise them to a higher height and add a storage bin. The question is: since multiple vessels need to be fed, how can the packaging be opened? How can dust be prevented? And how can accurate measurement be achieved? Consider using a diaphragm pump for feeding as well, but its large volume makes implementation difficult; experienced personnel should discuss this.
Send the powder to the manufacturers of conveying equipment for testing; there are many options available such as vacuum suction, air conveyance, chain conveyors, and bucket elevators. It mainly depends on the properties of the material, and testing is necessary
It is entirely possible to transfer the material from the first floor; a ton bag-based closed-unloading station can be placed on the first floor, and a vacuum-conveyed closed feeding system can be installed on the reactor. This allows for efficient nitrogen displacement followed by closed feeding. When the material enters the reactor, the oxygen content can be reduced to 4%, or even down to 1%； The simplest and most direct approach is to use bags with a specified weight; that is, a bag of the appropriate weight is used for materials that require that much weight. Using weighing-based metering for transportation is also an option, but it will lead to other problems later on.
