Description

Technical Field

[0001] The utility model relates to the technical field of powder feeding for hazardous chemical production, in particular to a powder feeding device for hazardous chemical production. Background Art

[0002] In hazardous chemical production, powdered raw materials or additives are often fed into the production line for various chemical reactions or physical treatments. These powders are typically stored and transported in ton bags, large plastic woven bags containing approximately one ton of powder. These bags have four lifting rings on the outside, allowing them to be lifted and moved using equipment such as cranes or forklifts.

[0003] At present, the commonly used powder delivery methods are as follows:

[0004] Manual bag opening and delivery. This method involves hoisting ton bags above the production line, cutting the bottom of the bags with a knife, and allowing the powder to fall naturally into the production line. The disadvantages of this method are: first, the operator needs to climb onto the bag to open it, which poses a safety hazard; second, the powder falling into the production line easily generates a large amount of dust, polluting the environment and endangering personnel health; third, the amount of powder delivered is difficult to control, which can easily lead to waste or insufficient powder.

[0005] Mechanical bagging and delivery. This method involves hoisting the ton bag onto a dedicated bagging machine, which uses a blade or other means to cut the bottom of the bag and deliver the powder to the production line. The disadvantages of this method are: first, the bagging machine is expensive and requires a large amount of space; second, the operation and maintenance of the bagging machine are relatively complex and require professional personnel; third, the bagging machine has limited applicability and has certain requirements for the shape and size of the ton bag, making it unsuitable for different powder types and production needs.

[0006] Vacuum suction feeding. This method involves hoisting the ton bag onto a vacuum suction device, which draws the powder through a pipe and then delivers it to the production line through another pipe. The disadvantages of this method are: first, the vacuum suction device is expensive and requires a large amount of space; second, the operation and maintenance of the vacuum suction device is also complex and requires professional personnel; third, the vacuum suction device is inefficient and has high requirements for powder fluidity, making it unsuitable for different powder types and production needs.
