A vacuum degassing packaging system for inorganic flame retardant powder

Abstract

The invention relates to a vacuum degassing packaging system for inorganic flame retardant powder. The vacuum degassing packaging system for inorganic flame retardant powder comprises a bin, a feeding pipe, a vacuum device, a filter device and a packaging device. The bin is used for containing the powder and comprises an outlet in the bottom, an inlet corresponding to the outlet and a pressure reduction opening. The feeding pipe is connected with the inlet and used for bringing the powder into the bin through air flow. The vacuum device is connected with the pressure reduction opening. The filter device is arranged between the pressure reduction opening and the vacuum device and used for stopping the powder. The packaging device is connected with the outlet and used for packaging and bagging the powder. A material return pipe is further arranged between the packaging device and the feeding pipe and used for separating gas from the powder in the packaging device. According to the vacuum degassing packaging system for the inorganic flame retardant powder, the packaging process is simplified, equipment cost of a workshop is reduced, trouble of manual maintenance is avoided, the labor intensity of manual operation is reduced, and investment and operation cost are reduced; and the packaging process can be stable and continuous, and packaging efficiency is improved.

Description

technical field [0001] This field relates to feeding or unloading mechanism, especially refers to the improvement of packaging technology for inorganic flame retardant powder or powdery materials. Background technique [0002] In the prior art, magnesium hydroxide flame retardant inorganic flame retardant powder needs to be transported by airflow in the pipeline, so in the packaging stage of inorganic flame retardant powder, the packaging bag will be very bulging due to the inclusion of a large amount of gas, which is inevitable Affects the efficiency of packaging encapsulation. [0003] In the prior art, in order to solve the above-mentioned packaging problem, a packaging dust collector (for example, a cloth bag filter) is connected to one side of the packaging device to remove the gas in the packaging bag in time, reduce the air pressure of the packaging bag, and make the inorganic flame retardant The powder is smoothly filled into the bag. However, during the process of...

Problems solved by technology

In this way, it is found that the bag filter not only takes up limited space in the workshop, but also frequently suspends the operation of the packaging system, and requires regular maintenance by staff, which increases production costs; at the same time, it also seriously affects packaging efficiency and delays production; In addition, different Inorganic flame retardant powder products cannot be mixed with bag filters, otherwise the inorganic flame retardant powder on the bag cannot be recycled
