[0002] Sodium m-nitrobenzenesulfonate is an organic compound commonly used as an industrial chemical in the synthesis of dyes and pharmaceuticals. It consists of a nitro group (NO2) and a sulfonic acid group (SO3Na) at the meta-position of a benzene molecule. As a chemical substance containing both nitro and sulfonic acid groups, sodium m-nitrobenzenesulfonate participates in reactions including electrophilic substitution and reduction reactions. For example, the nitro group can be reduced to an amino group, and the sulfonic acid group can participate in reactions with other compounds. In summary, sodium m-nitrobenzenesulfonate is an important chemical intermediate widely used in the synthesis of dyes and pharmaceuticals.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example

[0027] Reference Figures 1-4 A centrifugal apparatus for purifying sodium m-nitrobenzenesulfonate, comprising:

[0028] Outer shell 1;

[0029] The components include a motor 2, a rotating seat 3, a connecting rod 4, a fixing ring 5, a fixing sleeve 6, a separating cylinder 7, and a fixing plate 13. The motor 2 is fixedly connected to the bottom of the outer casing 1, and the output shaft of the motor 2 extends into the interior of the outer casing 1. The rotating seat 3 is rotatably connected to the bottom of the outer casing 1, and the bottom of the rotating seat 3 is fixedly connected to the top of the output shaft of the motor 2. There are four connecting rods 4, which are fixedly connected to the top of the rotating seat 3 at equal intervals. The fixing ring 5 is fixedly connected to the top of the connecting rod 4. There are two fixing sleeves 6 and two fixing plates 13. The two fixing sleeves 6 are symmetrically fixedly connected to the top of the fixing ring 5. The separating cylinder 7 is movably connected to the top of the rotating seat 3. The two fixing plates 13 are symmetrically slidably connected to the top of the separating cylinder 7, and the fixing plates 13 and the fixing sleeves 6 are engaged.

[0030] The fixing mechanism is connected to the fixing plate 13 and is used to fix the separation cylinder 7.

[0031] The above-mentioned mechanism allows the motor 2 to easily drive the rotating seat 3 to rotate, thereby making the separation cylinder 7 rotate, which facilitates the centrifugation of sodium m-nitrobenzenesulfonate. The fixing mechanism facilitates the movement of the fixing plate 13, and the fixing plate 13 facilitates the fixing of the separation cylinder 7.

[0032] As a preferred embodiment of the present invention, the fixing mechanism includes: a turntable 8, a rotating rod 9, an insert rod 10, and two pull rods 12;

[0033] The turntable 8 is rotatably connected to the top of the separating cylinder 7, and the rotating rod 9 is fixedly connected to the top of the turntable 8. The insert rod 10 passes through the rotating rod 9. The top of the separating cylinder 7 has two slots, both of which engage with the insert rod 10. The two pull rods 12 are rotatably connected to the top of the turntable 8, and the bottom of the two pull rods 12 is rotatably connected to the top of the corresponding fixing plate 13. The insertion rod 10 moves and disengages from the slot, thereby unlocking the rotating rod 9. At this time, pushing the rotating rod 9 to rotate will drive the turntable 8 to rotate. The rotation of the turntable 8 will pull the two pull rods 12. The movement of the pull rods 12 will drive the two fixing plates 13 to move closer to each other and disengage from the fixing sleeve 6, thereby unlocking the separating cylinder 7.

[0034] As a preferred embodiment of this utility model, the top of the separating cylinder 7 is symmetrically fixedly connected with two fixing frames 14. The outer walls of the two fixing plates 13 are slidably connected to the inner walls of the corresponding fixing frames 14. The fixing frames 14 can conveniently limit the fixing plates 13, so that the fixing plates 13 can move laterally stably.

[0035] As a preferred embodiment of this utility model, a spring 11 is sleeved on the outer wall of the insertion rod 10. The top of the spring 11 is fixedly connected to the outer wall of the insertion rod 10, and the bottom of the spring 11 is fixedly connected to the top of the rotating rod 9. The elastic force of the spring 11 facilitates pulling the insertion rod 10 to reset and engage with the slot.

[0036] As a preferred embodiment of this utility model, the inner wall of the fixing ring 5 is symmetrically provided with sliding grooves, and the outer wall of the separating cylinder 7 is symmetrically fixedly connected with sliders. There are four sliders and four sliding grooves. The outer walls of the four sliders are slidably connected to the inner walls of the corresponding sliding grooves. Through the cooperation of the sliders and the sliding grooves, the separating cylinder 7 can be conveniently limited, and the fixing ring 5 can be conveniently rotated to drive the separating cylinder 7 to rotate.

[0037] As a preferred embodiment of this utility model, the top of the outer shell 1 is provided with a through hole, and the inner wall of the through hole is rotatably connected to the outer wall of the fixing ring 5 through a rotating sleeve. The through hole facilitates the fixing ring 5 to drive the separating cylinder 7 to rotate on the inner wall of the outer shell 1.

[0038] It should be noted that the specific model of motor 2 used can be selected by those skilled in the art, and the above-mentioned motor 2 and other related technologies are all existing technologies, which will not be elaborated on in this solution.

[0039] The working principle of this utility model is as follows: In actual use, when it is necessary to purify sodium m-nitrobenzenesulfonate by centrifugation, the sodium m-nitrobenzenesulfonate to be processed is placed into the separation cylinder 7. At this time, the insertion rod 10 is pulled upward. The movement of the insertion rod 10 will disengage from the slot, thereby unlocking the rotating rod 9. At the same time, the movement of the insertion rod 10 will stretch the spring 11. At this time, pushing the rotating rod 9 to rotate will drive the turntable 8 to rotate. The rotation of the turntable 8 will pull the two pull rods 12. At this time, the movement of the pull rods 12 will drive the two fixing plates 13 to move closer to each other. Then, the separation cylinder 7 can be inserted into the fixing ring 5, and the slider is inserted into the slide groove. The separation cylinder 7 is limited by the cooperation of the slider and the slide groove. At this time, the rotating rod 9 is pushed to reset. The rotation will cause the turntable 8 to rotate, which in turn will cause the two pull rods 12 to move. The movement of the pull rods 12 will push the two fixed plates 13 to move to a side away from each other. The fixed plate 13 is limited by the fixed frame 14, so that the fixed plate 13 moves horizontally in a stable manner. The fixed plate 13 is reset and engaged with the fixed sleeve 6 to fix the separation cylinder 7. When the insertion rod 10 moves to the position corresponding to the slot, the insertion rod 10 is released. At this time, the spring 11 loses its restraint and causes the insertion rod 10 to move down and reset, thereby fixing the rotating rod 9 and preventing the rotating rod 9 from being accidentally touched and rotating, which would cause the separation cylinder 7 to unlock. At this time, starting the motor 2 can drive the rotating seat 3 to rotate, thereby driving the separation cylinder 7 to rotate and achieve the effect of purification and centrifugation of sodium p-nitrobenzenesulfonate.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
