A system and production process based on continuous production of isopropylhydroxylamine

Abstract

The present invention relates to the field of isopropylhydroxylamine production. The present invention discloses a system and a production process based on the continuous production of isopropylhydroxylamine. The problem to be solved by the present invention is that hydrogen peroxide and other catalysts need to be continuously adjusted during the stirring process. If the catalyst particles are added when the catalyst particles are added, the catalyst particles may be caused to stick, affecting the effect of the catalyst and its mixing. In the present invention, when the rotating frame drives the stirring frame to stir the materials in the stirring barrel during the rotation of the rotating frame, it can drive the set magnet frame to flip back and forth and turn the N level and S level of the magnet frame, thereby making the conical barrel reciprocate. When the conical barrel reciprocates, the intermittent contact with the ball on the clamping rod can control the discharge of the auxiliary discharge piece. In the process of stirring, the material is gradually and intermittently added to avoid the catalyst from accumulating into blocks in the stirring barrel, thereby improving the working efficiency of stirring.

[0011] Preferably, the method for using the system based on continuous production of isopropylhydroxylamine comprises the following steps:

[0012] S1: First, isopropylamine, deionized water and modified catalyst are placed in a mixing barrel to heat up, and then the driving disc is rotated under the drive of the driving motor. The driving disc rotates the transmission disc through the transmission belt on the transmission disc, and the transmission disc drives the transmission rod to rotate, so that the transmission gear can drive the driving gear to rotate. When the driving gear drives the driving rod to rotate, the rotating frame at the bottom of the driving rod will rotate with the driving rod as the center of the circle. When the rotating frame rotates, the positioning rods arranged on the two side walls of the rotating frame will synchronously drive the driving bevel gear to rotate in the bearing barrel. At this time, the driving bevel gear will synchronously drive the rotating bevel gear meshing with it to rotate. The rotation of the rotating bevel gear drives the rotating sleeve to rotate. A driving belt is arranged between the rotating sleeve and the stirring rod, and then when the rotating sleeve rotates, it can drive the driving belt to rotate the stirring rod. At this time, the stirring frame on the stirring rod will rotate and stir in the mixing barrel with the stirring rod as the center of the circle, so that the isopropylamine, deionized water and modified catalyst in the mixing barrel can be stirred and mixed, and the stirring efficiency of the materials can be improved by arranging a plurality of stirring frames around the outer wall of the mixing barrel so that the materials can be fully mixed;

[0013] S2: When the driving rod drives the rotating frame to rotate, the rotating frame rotates around the center of the driving rod, and the transmission bevel gear set on the rotating rod will rotate under the action of the fixed bevel gear. The rotation of the transmission bevel gear drives the rotating rod to rotate. The rotation of the rotating rod can drive the first turntable to rotate through the connecting belt between the second turntable and the first turntable. The first turntable drives the bearing rod to rotate, which can make the magnet frame set on the bearing rod flip back and forth. The N-level and S-level on the magnet frame reciprocate to adjust their positions, so that when the magnet frame contacts the magnetic block at the top of the conical barrel, it drives the magnetic block to make the moving column move back and forth up and down in the inner barrel. When the moving column moves back and forth up and down, the conical barrel will contact the ball set on the clamping rod, thereby driving the ball to make the clamping rod gradually squeeze into the rotating sleeve. The clamping rod is pressed to dock with the inner wall of the rotating sleeve. At this time, the rotating bevel gear rotates and drives the corresponding clamping rod to rotate, and then the clamping rod can drive the subsequent auxiliary discharging parts to perform discharging operations. Through this arrangement, when the rotating frame drives the stirring frame to stir the materials in the mixing barrel during the rotation, it can drive the set magnet frame to flip back and forth and turn the N level and S level of the magnet frame, so that the conical barrel moves back and forth. When the conical barrel moves back and forth, the intermittent contact with the ball on the clamping rod can control the discharging of the auxiliary discharging parts, and then the catalyst to be stirred can be placed in the annular disc during the stirring process. In the stirring process, the catalyst is gradually and intermittently added to avoid the catalyst from accumulating in the stirring barrel, thereby improving the stirring work efficiency.

[0014] S3: When the clamping rod is clamped with the inner wall of the rotating bevel gear, the rotating bevel gear rotates to drive the clamping rod to rotate, and the spiral discharging rod at the other end of the clamping rod will rotate. The spiral discharging rod rotates in the discharging slot, and then the material in the annular disc can be rotated and transported to the mixing barrel, realizing intermittent material delivery operation, avoiding accumulation of materials during continuous delivery and effectively controlling the delivery of materials.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, firstly, isopropylamine, deionized water and modified catalyst are placed in a stirring barrel to be heated, and then the driving disc is rotated under the drive of a driving motor, and the driving disc rotates the transmission disc through a transmission belt on the transmission disc, and the transmission disc drives the transmission rod to rotate, so that the transmission gear can drive the driving gear to rotate, and when the driving gear drives the driving rod to rotate, the rotating frame at the bottom of the driving rod will rotate with the driving rod as the center of the circle, and when the rotating frame rotates, the positioning rods arranged on the two side walls of the rotating frame will synchronously drive the driving bevel gear to rotate in the bearing barrel, and at this time, the driving bevel gear will synchronously drive the rotating bevel gear meshed with it to rotate, and the rotating bevel gear rotates to drive the rotating sleeve to rotate, and a driving belt is arranged between the rotating sleeve and the stirring rod, and then when the rotating sleeve rotates, it can drive the driving belt to rotate the stirring rod, and at this time, the stirring frame on the stirring rod will rotate and stir in the stirring barrel with the stirring rod as the center of the circle, and then the isopropylamine, deionized water, modified catalyst and other materials in the stirring barrel can be stirred and mixed, and the stirring efficiency of the materials can be improved by arranging a plurality of stirring frames around the outer wall of the stirring barrel so that the materials can be fully mixed.

[0017] In the present invention, when the driving rod drives the rotating frame to rotate, the rotating frame rotates around the center of the driving rod, and the transmission bevel gear arranged on the rotating rod rotates under the action of the fixed bevel gear. The rotation of the transmission bevel gear drives the rotating rod to rotate. The rotation of the rotating rod can drive the first rotating disk to rotate through the connecting belt between the second rotating disk and the first rotating disk. The first rotating disk drives the bearing rod to rotate, thereby enabling the magnet frame arranged on the bearing rod to flip back and forth. The N-level and S-level on the magnet frame reciprocate to adjust their positions, so that when the magnet frame contacts the magnetic block at the top of the conical barrel, the magnetic block is driven to enable the moving column to move back and forth up and down in the inner cylinder. When the moving column moves back and forth up and down, the conical barrel will contact the ball arranged on the clamping rod, thereby driving the ball to make the clamping rod gradually move toward the inside of the rotating sleeve. The clamping rod is extruded to dock with the inner wall of the rotating sleeve. At this time, the rotating bevel gear will drive the corresponding clamping rod to rotate, and then the clamping rod can drive the subsequent auxiliary discharging parts to perform discharging operations. Through this arrangement, when the rotating frame drives the stirring frame to stir the materials in the mixing barrel during rotation, it can drive the set magnet frame to flip back and forth and turn the N and S levels of the magnet frame, so as to make the conical barrel reciprocate. When the conical barrel reciprocates, the intermittent contact with the ball on the clamping rod can control the discharging of the auxiliary discharging parts, and then the catalyst required for stirring can be placed in the annular disc during the stirring process. In the process of stirring, the material is gradually and intermittently added to avoid the catalyst from accumulating into blocks in the stirring barrel, thereby improving the stirring work efficiency.

[0018] In the present invention, when the clamping rod is clamped with the inner wall of the rotating bevel gear, the rotating bevel gear rotates to drive the clamping rod to rotate, and the spiral discharging rod at the other end of the clamping rod will rotate. The spiral discharging rod rotates in the discharging slot, and then the material in the annular disc can be rotated and transported to the mixing barrel, realizing intermittent material delivery operation, avoiding accumulation of materials during continuous delivery and effectively controlling the delivery of materials.

Through this arrangement, when the rotating frame 31 rotates and drives the stirring frame 316 to stir the materials in the stirring barrel 11, it can drive the set magnet frame 39 to flip back and forth and turn the N level and S level of the magnet frame 39, so that the conical barrel 42 reciprocates. When the conical barrel 42 reciprocates, the intermittent contact with the ball 54 on the clamping rod 52 can control the discharging of the auxiliary discharging piece 5, and then the catalyst required for stirring can be placed in the annular disc 51 during the stirring process. In the stirring process, the material is gradually and intermittently added to avoid the catalyst from accumulating into blocks in the stirring barrel 11, thereby improving the stirring work efficiency.

[0043] S3: When the clamping rod 52 is clamped with the inner wall of the rotating bevel gear 313, the rotating bevel gear 313 rotates to drive the clamping rod 52 to rotate, and the spiral discharging rod 55 at the other end of the clamping rod 52 will rotate. The spiral discharging rod 55 rotates in the discharging slot 56, and then the material in the annular disc 51 can be rotated and transported to the mixing barrel 11, realizing intermittent material delivery operation, avoiding accumulation of materials during continuous delivery and effectively controlling the delivery of materials.

Control valves are provided at both the feed port (6) and the discharge port (61).

4. A method for using a system based on continuous production of isopropylhydroxylamine, comprising the following steps: S1: First, isopropylamine, deionized water and a modified catalyst are placed in a stirring barrel (11) and heated. Then, the driving disc (22) is rotated under the drive of a driving motor (21). The driving disc (22) rotates the driving disc (24) through a driving belt (25) on the driving disc (24). The driving disc (24) drives the driving rod (23) to rotate, so that the driving gear (26) can drive the driving gear (28) to rotate. When the driving gear (28) drives the driving rod (27) to rotate, the rotating frame (31) at the bottom of the driving rod (27) will rotate with the driving rod (27) as the center of the circle. When the rotating frame (31) rotates, the positioning rods (310) provided on the two side walls of the rotating frame (31) will synchronously drive the driving bevel gear (311) to rotate in the carrying barrel (13). At this time, the driving bevel gear (311) will synchronously drive the rotating bevel gear (313) meshing with it to rotate, and the rotating bevel gear (313) will drive the rotating sleeve (312) to rotate. A driving belt (315) is provided between the rotating sleeve (312) and the stirring rod (314). When the rotating sleeve (312) rotates, the driving belt (315) can be driven to rotate the stirring rod (314). At this time, the stirring frame (316) on the stirring rod (314) will rotate and stir in the stirring barrel (11) with the stirring rod (314) as the center of the circle, thereby stirring and mixing the isopropylamine, deionized water and modified catalyst material in the stirring barrel (11). The stirring efficiency of the materials can be improved by arranging a plurality of stirring frames (316) around the outer wall of the stirring barrel (11), so that the materials can be fully mixed. S2: When the driving rod (27) drives the rotating frame (31) to rotate, the rotating frame (31) rotates around the center of the driving rod (27), and the transmission bevel gear (33) provided on the rotating rod (32) rotates under the action of the fixed bevel gear (34). The rotation of the transmission bevel gear (33) drives the rotating rod (32) to rotate. The rotation of the rotating rod (32) drives the first rotating disk (36) to rotate through the connecting belt (38) between the second rotating disk (37) and the first rotating disk (36). The first rotating disk (36) drives the bearing (36) to rotate. The carrier rod (35) rotates to cause the magnet frame (39) disposed on the carrier rod (35) to flip back and forth, and the N-stage and S-stage on the magnet frame (39) adjust their positions back and forth, so that when the magnet frame (39) contacts the magnetic block (43) on the top of the conical barrel (42), the magnetic block (43) is driven to cause the movable column (41) to move back and forth up and down in the inner cylinder (317). When the movable column (41) moves back and forth up and down, the conical barrel (42) contacts the ball (54) disposed on the clamping rod (52), thereby driving the movable column (41) to move back and forth up and down in the inner cylinder (317). The sphere (54) causes the clamping rod (52) to be gradually pressed toward the inside of the rotating sleeve (312), so that the clamping rod (52) and the inner wall of the rotating sleeve (312) are connected. At this time, when the rotating bevel gear (313) rotates, it drives the corresponding clamping rod (52) to rotate, and then the clamping rod (52) can drive the subsequent auxiliary discharge member (5) to perform a discharge operation. Through this arrangement, when the rotating frame (31) rotates, it drives the stirring frame (316) to stir the material in the stirring barrel (11). The magnet frame (39) can be driven to flip and rotate the N and S stages of the magnet frame (39) back and forth, thereby causing the conical barrel (42) to reciprocate. When the conical barrel (42) reciprocates, the intermittent contact with the ball (54) on the clamping rod (52) can control the discharge of the auxiliary discharge member (5), thereby allowing the catalyst to be stirred to be placed in the annular disc (51) during the stirring process. During the stirring process, the catalyst is gradually and intermittently added to avoid the catalyst from accumulating into blocks in the stirring barrel (11), thereby improving the stirring work efficiency. S3: When the engaging rod (52) engages with the inner wall of the rotating bevel gear (313), the rotating bevel gear (313) rotates to drive the engaging rod (52), and the spiral discharging rod (55) at the other end of the engaging rod (52) rotates. The spiral discharging rod (55) rotates in the discharging slot (56), and the material in the annular disc (51) is then conveyed to the mixing barrel (11) through rotation, thereby realizing an intermittent material delivery operation, avoiding accumulation of materials during continuous delivery, and effectively controlling the delivery of materials.
