Problems solved by technology

Although nitrocellulose with a nitrogen content of less than 12.5% ​​is relatively stable, when heated or stored for a long time, it will gradually decompose and release acid, lowering the ignition point, and may spontaneously ignite and explode
This reduces work efficiency and increases the packaging process, making the lifting efficiency too low, which is not conducive to mass production

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the drawings.

[0017] Such as figure 1 As shown, the present invention first dewaters the nitrocellulose slurry or replaces the water with alcohols, and then uses the conveying mechanism to transport the nitrocellulose to the metal detector. The metal detector is used to remove the metal contained in the nitrocellulose, and then the metal is removed The nitrocellulose is sent to the tablet press for tableting, and finally the compressed nitrocellulose is packaged. Dehydration is mainly achieved by a centrifuge. The nitrocellulose slurry is sent to the centrifuge, and the nitrocellulose slurry is continuously dewatered by centrifugation. Alcohols can also be used to replace the water, that is, add isopropanol, butanol and alcohol Replacement and flooding with alcohols. After dehydration or flooding, the nitrocellulose is transported to the next process through a conveying mechanism. This usually inv...

Abstract

The invention discloses a continuous packaging production process and in particular relates to a continuous nitrocotton packaging production process. The continuous nitrocotton packaging production process through which the occupied volume of the nitrocotton is reduced during packaging comprises the following steps of: dehydrating nitrocotton slurry or dewatering nitrocotton slurry through alcohol substance replacement; conveying the nitrocotton to a metal detector by utilizing a conveying mechanism, and removing metals mixed in the nitrocotton by utilizing the metal detector; feeding the nitrocotton in which the metals are removed into a tablet press for pressing tablets; and finally, packaging the pressed nitrocotton. Because the nitrocotton is pressed before packaging, the apparent density of the nitrocotton is improved, so that the occupied volume is greatly reduced during packaging, the more nitrocotton can be accommodated in the packaging structure with the same specification; and therefore, the storage and transportation cost is saved.

Description

Technical field [0001] The invention relates to a continuous packaging production process, in particular to a continuous packaging production process of nitrocellulose. Background technique [0002] Nitrocellulose is white or slightly yellow cotton wool, soluble in acetone. The scientific name is cellulose nitrate, formerly known as nitrocellulose and nitrocellulose. Nitrocellulose is a polymer with a large molecular weight. Nitrocellulose is highly flammable and explosive, and its degree of danger depends on the degree of nitrification. Nitrocellulose with a nitrogen content of 12.5% ​​or more is extremely dangerous and burns when it encounters a fire. It can accelerate its decomposition and spontaneous combustion when the temperature exceeds 40℃. Although nitrocellulose with a nitrogen content of less than 12.5% ​​is relatively stable, it will gradually decompose and release acid after being heated or stored for a long time, reducing the ignition point, and may also spontane...
