Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] The structure of a spiral densification device for nitrocellulose provided by the invention is as follows: figure 1 As shown, it includes a motor 1 and a conveying device with a cavity structure inside. The motor 1 is connected with a screw shaft 5. The conveying device includes a conveying section 2, a variable diameter section 3 and a pressure-holding discharge section 4 connected end to end in sequence. The screw shaft 5 runs through the conveying section 2, the variable diameter section 3 and the pressure-holding discharge section 4 along the axial direction of the conveying device; The self-aligning bearing is movable and fixed; the conveying section 2 is set close to the end of the motor 1, and is sealed at the contact with the screw shaft 5 or the motor 1. The inner diameter of the variable diameter section 3 gradually decreases...

Abstract
The invention discloses a spiral density increasing device for nitrocellulose. A motor and a conveying device which is internally of a cavity structure are included. The motor is connected with a spiral rotation shaft. The conveying device comprises a conveying section, a reducing section and a pressure maintaining discharging section which are sequentially connected. The spiral rotation shaft penetrates through the conveying section, the reducing section and the pressure maintaining discharging section in the axial direction of the conveying device. The conveying section is close to one end of the motor, the position contact with the spiral rotation shaft or the motor is sealed, the inner diameter of the reducing section starts to be gradually reduced from the conveying section for extrusion density increasing of the nitrocellulose, and the part, away from one end of the reducing section, of the conveying section is provided with a feeding port. According to the spiral density increasing device for the nitrocellulose, the spiral rotation shaft is utilized for extruding the nitrocellulose, the labor intensity of personnel is reduced, dust is reduced, the stacking density of the nitrocellulose is increased to the degree equivalent to manual extrusion, the dissolving effect is not influenced, and later usage of users is not influenced.
Description
technical field [0001] The invention belongs to the technical field of cellulose densification, and in particular relates to a spiral densification device for nitrocellulose. Background technique [0002] The bulk density of flocculent nitrocellulose in its natural state is 0.1g / cm 3 Or so, if it is not densified, the packaging shipping cost will be very high. At present, the existing densification technology of flocculent nitrocellulose is manual intervention extrusion densification and rolling roller extrusion densification. Manual intervention is to manually shake and squeeze the materials in the package during the process of nitrocellulose receiving and packaging. This method is labor-intensive, has poor densification effect, many on-site operators, and relatively large dust, which poses safety hazards. Roller extrusion is to use a rolling machine to extrude nitrocellulose. After extrusion, nitrocellulose is a sheet of 3-5mm. After densification, the density of nitroce...
