[0013] The present invention provides a polyethylene polyamine derivative synthesis reactor, which has the following beneficial effects:

[0014] 1. The polyethylene polyamine derivative synthesis reactor cooperates with the dividing cylinder and the auger plate to make the materials on both sides of the dividing cylinder circulate during the rotation, so that the solid-liquid mixed material can drive the solid material to flow during the circulation of the liquid, and evenly contact the heat transferred by the heat conduction mechanism, thereby avoiding directly driving the material to rotate for stirring and mixing, resulting in the accumulation of the solid material at the bottom of the outer periphery of the material under the action of centrifugal force, resulting in uneven heating between the materials.

[0016] 3. The polyethylene polyamine derivative synthesis reactor, through the cooperation of the pad and the inclined block, increases the internal air pressure, so that the sliding plate is pushed up by the pressure, driving the connecting rod and the inclined block to move upward, and utilizing the opposite surface of the pad to be an inclined surface inclined from top to bottom to the outside and the outer side of the inclined surface block to be an inclined surface inclined from top to bottom to the outside, so that the pad drives the arc slider to expand, increases the contact pressure between the rubber ring and the inside of the reaction tank, and as the air pressure increases, the contact pressure is also increased, thereby improving the sealing of the equipment during the reaction.

[0017] Fourth, the polyethylene polyamine derivative synthesis reactor has arc-shaped annular grooves uniformly arranged on the inner wall of the corrugated cylinder. When the hot water passes through the process, the flow is restricted when it reaches the convex position and diffuses to both sides. In the process of hot water introduction, it is evenly diffused around the outside of the reaction tank. When the hot water conducts heat, the temperature of the hot water on the same horizontal plane remains consistent, avoiding uneven heating of the reaction tank, which makes it impossible to transfer the same amount of heat to the material.

At the same time, during the rotation of the shaft sleeve 27, the separation cylinder 21 is driven to rotate through the connecting ring 29, and during the rotation of the separation cylinder 21, the inner auger plate 28 and the outer connecting strip 22 are driven to rotate. A separation cylinder 21 is fixedly installed on the outer side of the connecting ring 29, an auger plate 28 is fixedly installed between the separation cylinder 21 and the shaft sleeve 27, a connecting strip 22 is fixedly installed on the outer side of the separation cylinder 21, the connecting strip 22 is evenly installed along the center position of the circle of the separation cylinder 21, and a brush strip 25 is fixedly installed on the outer side of the connecting strip 22. During the rotation of the auger plate 28, the spiral shape drives the material below to surge upward, and after reaching the top of the separation cylinder 21, it diffuses outward under the action of centrifugal force, and the material on the outside of the separation cylinder 21 moves up after the bottom material moves down to fill the space, so that the material inside and outside the separation cylinder 21 forms a circulating flow, and cooperates with the heat conduction mechanism 4 to heat the inner tank body of the reaction tank 1, and transfers heat to the material on the outside of the separation cylinder 21 for heating, and the outer side of the brush strip 25 contacts the inner wall of the reaction tank 1.

During the heating reaction of the material inside the reaction tank 1, the pressure inside the reaction tank 1 increases. Through the cooperation between the inner disk 305 and the outer disk 304, the gas inside the reaction tank 1 passes through the bearing 306 under the blockage of the inner disk 305 and the outer disk 304 and reaches the top of the outer disk 304 and the inner disk 305. The bottom of the cover plate 302 is fixedly installed with a sealing cylinder 312, and the bottom of the sealing cylinder 312 is fixedly installed with the inner disk 305. The inner wall of the inner disk 305 is connected to the connecting shaft 26. The outer side of the inner disk 305 is fixedly connected, and the outer side of the inner disk 305 is fixedly installed with a bearing 306. The inner disk 305 is rotatably installed with the outer disk 304 through the bearing 306. The outer side of the outer disk 304 contacts the inner wall of the reaction tank 1. The outer side of the sealing cylinder 312 is fixedly installed with a groove disk 310. The outer side of the groove disk 310 is evenly provided with sliding grooves, and the sliding grooves of the groove disk 310 are slidably installed with arc sliders 311. Under the action of air pressure, the sealing cylinder 312 blocks the gas inside the reaction tank 1, so that it pushes the sliding disk 308 along the groove disk 310. The inner wall slides upward, and during the sliding process, the connecting rod 313 drives the inclined surface block 314 to move upward. The inclined surface of the inclined surface block 314 slides and fits with the inclined surface of the cushion block 315. During the upward movement of the inclined surface block 314, the cushion block 315 is pushed to make the arc slider 311 expand outward, driving the rubber ring 309 to squeeze the inner wall of the reaction tank 1, thereby increasing the contact pressure at the gap position and improving the sealing performance. The outer side of the arc slider 311 is fixedly installed with a rubber ring 309, and the outer side of the rubber ring 309 is tightly fitted with the inner wall of the reaction tank 1.

[0037] The third embodiment is based on the first and second embodiments. Figures 8 to 9As shown, the heat conduction mechanism 4 includes a liquid inlet pipe 41 and a liquid outlet pipe 42. The liquid inlet pipe 41 is fixedly installed on the top of the outer side of the reaction tank 1, and the liquid outlet pipe 42 is fixedly installed on the bottom of the outer side of the reaction tank 1. A corrugated cylinder 46 is fixedly installed at the center position between the double-layer structures of the reaction tank 1. The inner wall of the corrugated cylinder 46 is evenly provided with arc-shaped annular grooves along the axial direction. A top ring 48 is fixedly installed on the top of the double-layer gap of the reaction tank 1. The liquid inlet pipe 41 and the liquid outlet pipe 42 are connected with the hot water pipeline, so that the hot water is introduced into the gap of the double-layer tank body of the reaction tank 1 along the liquid inlet pipe 41, and enters the inner side of the corrugated cylinder 46 by its own gravity under the restriction of the inclined ring 47 and the top ring 48. The arc-shaped annular grooves evenly provided on the inner side of the corrugated cylinder 46 along the axial direction limit the flow rate of the flowing hot water, so that it slowly passes through the corrugated cylinder On the inner side of 46, a bevel ring 47 is fixedly installed on the top of the bellows 46, the bevel ring 47 is located below the liquid inlet pipe 41, and the top ring 48 is located above the liquid inlet pipe 41. A through groove ring 45 is fixedly installed on the bottom of the bellows 46, and through grooves are evenly opened on the top of the through groove ring 45. A spiral plate 44 is fixedly installed on the bottom of the through groove ring 45. The spiral plates 44 are evenly installed along the center position of the through groove ring 45, and a bottom ring 43 is fixedly installed on one end of the spiral plate 44 away from the through groove ring 45. When hot water flows to the bottom of the bellows 46, the hot water is evenly guided by the through groove ring 45, so that the material flows evenly downward and enters the gap between the spiral plates 44. Finally, the hot water after the heat conduction is completed is led out of the reaction tank 1 through the liquid outlet pipe 42, and the spiral plate 44 is located above the liquid outlet pipe 42.

[0038] When in use, the staff introduces the materials required for the synthesis of polyethylene polyamine derivatives into the reaction tank 1, then seals the reaction tank 1 with the sealing mechanism 3, then connects the hot water pipe with the heat conducting mechanism 4, so that the hot water is introduced into the gap of the double-layer structure of the reaction tank 1 to heat the materials in the reaction tank 1, and then starts the motor 7 to drive the stirring mechanism 2 to operate to stir the materials, and cooperates with the heat conducting mechanism 4 to evenly heat the materials during the reaction process.

[0039] After the material is introduced into the reaction tank 1, the cover plate 302 and the fixing ring 301 are fixedly connected by bolts 303, so that the rubber ring 309 and the outer disk 304 are closely attached to the inner wall of the reaction tank 1. During the heating reaction of the material inside the reaction tank 1, the pressure inside the reaction tank 1 increases. Through the cooperation between the inner disk 305 and the outer disk 304, the gas inside the reaction tank 1 passes through the bearing 306 under the obstruction of the inner disk 305 and the outer disk 304, and reaches the top of the outer disk 304 and the inner disk 305. Under, in cooperation with the sealing cylinder 312 to block the internal gas of the reaction tank 1, it pushes the sliding plate 308 to slide upward along the inner wall of the groove plate 310. During the sliding process, the connecting rod 313 drives the inclined surface block 314 to move upward. The inclined surface of the inclined surface block 314 slides with the inclined surface of the cushion block 315. During the upward movement of the inclined surface block 314, the cushion block 315 is pushed to make the arc slider 311 expand outward, driving the rubber ring 309 to squeeze the inner wall of the reaction tank 1, thereby increasing the contact pressure at the gap position and improving the sealing performance.

[0040] In the process of stirring the material inside the reaction tank 1 by the stirring mechanism 2, the motor 7 drives the connecting shaft 26 to rotate, so that the connecting shaft 26 drives the sleeve 27 and the connecting plate 23 to rotate, and the connecting plate 23 drives the stirring blade 24, so that the stirring blade 24 rotates at the bottom of the inner side of the reaction tank 1, driving the material inside the reaction tank 1 to be evenly mixed. At the same time, in the process of the rotation of the sleeve 27, the connecting ring 29 drives the separation cylinder 21 to rotate. In the process of the rotation of the separation cylinder 21, the inner auger plate 28 and the outer connecting strip 22 are driven to rotate. In the process of the rotation of the auger plate 28, the spiral shape drives the material below to surge upward, and after reaching the top of the separation cylinder 21, it diffuses outward under the action of centrifugal force. After the material on the outside of the separation cylinder 21 moves up, it moves downward to fill the space, so that the materials inside and outside the separation cylinder 21 form a circulating flow, and cooperate with the heat conduction mechanism 4 to heat the inner tank body of the reaction tank 1, and transfer the heat to the material on the outside of the separation cylinder 21 for heating.

[0041] In the heat conduction mechanism 4, the liquid inlet pipe 41 and the liquid outlet pipe 42 are connected with the hot water pipeline, so that the hot water is introduced into the gap of the double-layer tank body of the reaction tank 1 along the liquid inlet pipe 41, and enters the inner side of the corrugated cylinder 46 by its own gravity under the restriction of the inclined ring 47 and the top ring 48. The arc-shaped annular grooves uniformly opened along the axial direction on the inner side of the corrugated cylinder 46 limit the flow rate of the flowing hot water, so that it slowly passes through the inner side of the corrugated cylinder 46. When the hot water flows to the bottom of the corrugated cylinder 46, the hot water is uniformly guided by the through groove ring 45, so that the material flows evenly downward and enters the gap between the spiral plates 44. Finally, the hot water after the heat conduction is discharged out of the reaction tank 1 through the liquid outlet pipe 42.

[0042] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
