[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] like Figures 1-6 As shown, an o-nitroaniline reactor comprises: a reactor body 1, a carrier frame 6 and a servo motor 3.
[0029] The top of the kettle body 1 is provided with a feed port 2, and a plurality of heating boxes 13 are fixedly connected to the inner wall of the kettle body 1 along the axial direction. The inner wall of the heating box 13 is fixedly connected to a heating element 14. A carrier 6 is arranged at the bottom of the kettle body 1, and the carrier 6 is rotatably connected to the outer wall of the kettle body 1. The servo motor 3 is fixedly connected to the top of the kettle body 1, and the bottom of the servo motor 3 is fixedly connected to a rotating shaft 11. The outer wall of the rotating shaft 11 is fixedly connected to a stirring blade 12. Pour o-nitroaniline into the kettle body 1 from the feed port 2. A heater is provided in the kettle body 1 to heat o-nitroaniline. The servo motor 3 is operated to rotate the rotating shaft 11, which in turn rotates the stirring blade 12. The stirring blade 12 stirs the o-nitroaniline. In order to increase the heat exchange area of the o-nitroaniline, the heating element 14 is operated. The heat provided by the heating element 14 is transferred to the o-nitroaniline via the heating box 13. The use of the heating box 13 and the heating element 14 increases the heating area of the o-nitroaniline, improves the heat exchange efficiency of the o-nitroaniline, and thus improves the processing efficiency of the o-nitroaniline.
[0030] Among them, the supporting frame 6 provides support for the kettle body 1. When the o-nitroaniline is stirred in the kettle body 1, the rotating o-nitroaniline contacts the heating box 13. The heating box 13 can block the o-nitroaniline, thereby allowing the o-nitroaniline to further roll during the rotation process, thereby improving the stirring efficiency of the o-nitroaniline.
[0031] In some specific embodiments, the kettle body 1 is provided with a wire hole 15 along the axial direction of the heating element 14, the outer wall of the kettle body 1 is fixedly connected to a circular wire box 4, the bottom end of the kettle body 1 is fixedly connected to a discharge barrel 7, and the wire hole 15 is respectively communicated with the interior of the heating box 13 and the interior of the wire box 4. When the heating element 14 is running, the heating element 14 requires wires to transmit electrical energy. The wires are connected to the heating element 14, and then the wires pass through the wire hole 15 and gather in the wire box 4. The wire box 4 realizes the function of summarizing and collecting the wires.
[0032] In some specific embodiments, a battery 5 is fixedly connected to the top of the wire box 4, and the wires collected in the wire box 4 are connected to the battery 5. The battery 5 can provide electrical energy to the heating element 14 through the wires.
[0033] In some specific embodiments, the outer wall of the discharge barrel 7 is sleeved with a belt 8, and the belt 8 is sleeved with an output shaft 9 at the end away from the discharge barrel 7. The bottom end of the output shaft 9 is fixedly connected to a driving machine 10. In order to further improve the efficiency of the heating box 13 in stirring the o-nitroaniline, the driving machine 10 is running, and the driving machine 10 drives the output shaft 9 to rotate, and the output shaft 9 drives the belt 8 to move, and the belt 8 drives the discharge barrel 7 to rotate, and the discharge barrel 7 drives the kettle body 1 to rotate on the supporting frame 6, and the kettle body 1 drives the heating box 13 to rotate, and the heating box 13 stirs the o-nitroaniline, so that the heating box 13 can fully heat the o-nitroaniline, ensuring that the o-nitroaniline is heated evenly, and avoiding the phenomenon of uneven heating of the o-nitroaniline due to insufficient stirring. It should be noted that when the kettle body 1 rotates, the kettle body 1 drives the wire box 4 and the battery 5 to rotate, and the wire box 4 stores the wires to avoid the wires from being entangled due to the rotation of the kettle body 1.
[0034] In some specific embodiments, the stirring blade 12 is in a spiral shape. The shape of the stirring blade 12 can move the o-nitroaniline upward from the bottom of the kettle body 1. Part of the o-nitroaniline moving upward will flow around the stirring blade 12, thereby ensuring that the o-nitroaniline is fully stirred.
[0035] In some specific embodiments, the top of the heating box 13 is tilted to both sides, and a plurality of stirring grooves 16 are provided on the edge of the heating box 13. The cross-section of the stirring groove 16 is triangular. When the heating box 13 stirs o-nitroaniline, the stirring groove 16 provided in the heating box 13 increases the contact area between o-nitroaniline and the heating box 13, further improving the heat exchange area of o-nitroaniline. The shape of the stirring groove 16 can further stir the o-nitroaniline. When o-nitroaniline is discharged through the discharge barrel 7, the kettle body 1 can drive the heating box 13 to rotate, and the rotating heating box 13 can remove the o-nitroaniline remaining on the surface. The shape of the top of the heating box 13 can speed up the removal of o-nitroaniline from the top of the heating box 13, and avoid o-nitroaniline remaining on the top of the heating box 13, thereby ensuring that o-nitroaniline can be fully discharged.
[0036] The above describes several embodiments of the present invention in detail, but the present invention is not limited to these embodiments and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
