Description

Technical Field

[0001] This application relates to the field of mixing equipment technology, and in particular to mixing equipment for nitrocellulose production. Background Technology

[0002] As is well known, nitrocellulose, also known as cellulose nitrate, is an organic polymer compound with the chemical formula (C6H7N3O11)n. It is a product of the esterification reaction of cellulose with nitrate, and appears as white or slightly yellow cotton-like material. It is insoluble in water but soluble in organic solvents such as esters and acetone.

[0003] Currently, nitrocellulose is widely used as a binder for single-base, double-base, triple-base, modified double-base, and composite modified double-base propellants, and as a viscosity modifier in the manufacture of propellants or casting mixed explosives. In its production process, it is necessary to mix the water-containing nitrocellulose with the other material components, which is generally done using a mixer. However, the applicant has found that during the mixing process of nitrocellulose with the other material components, because nitrocellulose is not easy to disperse, it is easy for the other material components to be difficult to mix evenly with nitrocellulose. Secondly, a long time is required to ensure that the other material components are mixed evenly with nitrocellulose, which makes it impractical.

[0004] Therefore, in response to the aforementioned technologies, we propose a mixing device for nitrocellulose production. Utility Model Content

[0029] Please see Figures 1-4 In this embodiment of the invention, the mixing device for nitrocellulose production includes:

[0030] Base 1;

[0031] The main compartment 2 is mounted on the base 1 via a connecting component. The main compartment 2 is equipped with a compartment cover 3 that is compatible with it. A limit lock 4 is provided between the compartment cover 3 and the main compartment 2.

[0032] The drive motor 5 is installed in the base 1 through the connecting groove. The output shaft of the drive motor 5 is fixedly connected to the connecting shaft 6. The connecting shaft 6 extends into the main compartment 2 through the connecting ring 7.

[0033] Connecting bracket 8 is fixedly connected to connecting shaft 6;

[0034] The material discharge bin 9 is detachably connected to the connecting frame 8 via a limiting component;

[0035] A stirring rod 10 is fixedly connected to the bottom of the bin cover 3, and multiple stirring blades 11 are fixedly connected to the outside of the stirring rod 10.

[0036] A support assembly is disposed within the base 1 and is used to support the base 1 in the position of use.

[0037] This mixing device for nitrocellulose production, when in use, uses a support assembly to support the base 1 in the operating position. Then, a limiting assembly fixes the discharge bin 9 onto the connecting frame 8. The nitrocellulose to be mixed, along with other materials, is then added into the discharge bin 9. A limiting lock 4 then fixes the bin cover 3 onto the main bin 2, allowing the stirring rod 10 and multiple stirring blades 11 to be inserted into the discharge bin 9. Starting the drive motor 5 causes the connecting frame 8 to rotate via the connecting shaft 6, which in turn rotates the discharge bin 9. This, combined with the stirring rod 10 and multiple stirring blades 11 within the discharge bin 9, effectively mixes the materials within the bin.

[0038] exist Figure 1-3 In the middle: the connecting component includes two connecting plates 12, which are respectively set on the outer wall of the main body 2. The bottom of the connecting plate 12 is fixedly connected to the support column 13, and the other end of the support column 13 is fixedly connected to the base 1.

[0039] The mixing device for nitrocellulose production, through this structure, facilitates the fixed support of the main chamber 2 on the base 1 with the cooperation of the connecting plate 12 and the support column 13.

[0040] exist Figure 1-4 In the middle: the limiting component includes four positioning posts 14, which are all correspondingly set on the connecting frame 8. Four positioning blocks 15 are correspondingly set on the outer wall of the feeding bin 9. The positioning blocks 15 are slidably connected to the positioning posts 14 through positioning rings 16.

[0041] This mixing device for nitrocellulose production, through the arrangement of the positioning block 15, positioning ring 16 and positioning column 14, facilitates the fixing and limiting of the discharge bin 9 on the connecting frame 8, preventing it from shifting or falling off during the rotation of the connecting frame 8.

[0042] exist Figure 1-4The support assembly includes four support columns 17, which are all installed in the base 1 through connecting grooves. The other end of each support column 17 is fixedly connected to a support seat 18. The bottom of the support seat 18 is provided with an anti-slip rubber pad 19 to increase the friction between the support seat 18 and the ground. The outer wall of the discharge bin 9 is provided with two first handles 20 for users to pick up and use the discharge bin 9. The bin cover 3 is fixedly connected with a ring handle 21. The first handle 20 and the ring handle 21 are fixedly covered with anti-slip rubber sleeves 22 to increase the user's grip comfort.

[0043] In this embodiment, the drive motor 5 is a commercially available device known to those skilled in the art. It can be customized or selected according to actual needs. Here, we are only using it without making any structural or functional improvements. We will not go into details here. The drive motor 5 is equipped with a matching control switch. The installation position of the control switch is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0044] The implementation principle of the mixing device for nitrocellulose production in this application embodiment is as follows: First, the base 1 is supported and placed in the usage position by the mutual cooperation of multiple support columns 17 and support seats 18. Then, the discharge bin 9 is fixed and limited on the connecting frame 8 by the mutual cooperation of positioning columns 14, positioning blocks 15 and positioning rings 16. Then, the nitrocellulose to be stirred and other materials are put into the discharge bin 9. At the same time, the bin cover 3 is fixed and limited on the main bin body 2 by the setting limit lock 4, so that the stirring rod 10 and multiple stirring blades 11 are inserted into the discharge bin 9. Then, the user can start the drive motor 5. The drive motor 5 will drive the connecting frame 8 to rotate through the connecting shaft 6, so that the connecting frame 8 drives the discharge bin 9 to rotate. Thus, the stirring rod 10 and multiple stirring blades 11 in the discharge bin 9 can play the role of stirring the materials in the discharge bin 9.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
