[0044] As a further solution of the present invention: the impact rods on both sides of the support plate face opposite directions.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] 1. By setting a centrifugal cleaning component, when the driving motor drives the stirring rod to rotate clockwise, the first ratchet is limited by the first pawl, so that the rotating connecting bin cannot rotate with the stirring rod. During this process, the second ratchet rotates synchronously with the stirring rod, and the second pawl swings back and forth under the toggle of the second ratchet. When the driving motor drives the stirring rod to rotate counterclockwise, the second pawl blocks the second ratchet. At this time, the stirring rod drives the rotating connecting bin to rotate through the second ratchet and the second pawl, so that the rotating connecting bin can be driven to rotate when the stirring rod rotates counterclockwise, so that the material on the surface of the stirring rod is separated from the stirring rod under the action of centrifugal force;

[0047] 2. By setting a temperature-increasing drying mechanism, when the rotating connecting bin rotates synchronously with the stirring rod, the second transmission spur gear will drive the first transmission spur gear to rotate. At this time, the first transmission spur gear will drive the direct-connected sleeve to move back and forth left and right through the shift pin. When the piston rod moves away from the air cylinder as the direct-connected sleeve moves, the centrifugal contact unit operates at the same time, so that the temperature inside the mixing tank increases, and the air cylinder absorbs the hot air inside the mixing tank. In this process, the hot air inside the mixing tank enters the air cylinder through the connecting pipe, the corrugated telescopic pipe, and the drying bin, and the humidity of the air inside the mixing tank is reduced by the desiccant inside the drying bin. When the piston rod moves toward the air cylinder, the air inside the air cylinder will be discharged from the air cylinder. At the same time, the position of the connecting pipe will change with the movement of the direct-connected sleeve, so as to extract hot air from different positions inside the mixing tank, thereby further improving the drying efficiency of the air inside the mixing tank.

[0048] 3. By setting up a centrifugal contact unit, the rotation of the rotating connecting bin causes the transverse rod to move in the direction away from the stirring rod under the action of centrifugal force. During this process, the transverse rod pulls the rotating ring downward through the extrusion rod, so that the second contact piece contacts the first contact piece, thereby energizing the heater. At the same time, the extension frame loses its shielding of the bottom of the protective sleeve as the positioning ring moves downward. At this time, the heater will heat the air inside the mixing tank. At the same time, the hot air is dried by the drying bin, so that the moisture in the residual material inside the mixing tank is reduced, thereby reducing the viscosity between the residual material and the mixing tank, so that the dried material is separated from the mixing tank, thereby achieving the effect of self-cleaning of the equipment;

[0049] 4. By setting a vibration disengagement part, when the rotating connecting bin rotates, it will drive the splicing pipe to rotate. At this time, the splicing pipe drives the second transmission bevel gear to rotate through the first transmission bevel gear. When the second transmission bevel gear rotates, the transmission shaft will drive the half gear to rotate. The spur rack moves during the rotation of the half gear. At the same time, the impact rod will move away from the inner wall of the mixing tank with the pushing frame. When the tooth on the half gear is separated from the spur rack, the spur rack will quickly recover under the action of the elastic restoring force of the second telescopic spring, so that the impact rod will hit the inner wall of the mixing tank, thereby causing the mixing tank to vibrate as a whole, thereby improving the separation effect of the dried material and the mixing tank, and further improving the self-cleaning efficiency of the equipment.

The following describes an embodiment of the present invention based on its overall structure.

[0061] Example 1

[0062] See also Figures 1 to 8In an embodiment of the present invention, a high-viscosity polymer reaction stirring device with a self-cleaning function includes a stirring tank 1;

[0063] The driving motor 2 is arranged on the top of the stirring tank 1, and the output end of the driving motor 2 is connected to the stirring rod 4 extending into the interior of the stirring tank 1;

[0064] The feed port 3 is provided on the outer wall of the mixing tank 1;

[0065] The support plate 6 is mounted on the inner side of the mixing tank 1. The support plate 6 is rotatably connected to a rotating connecting bin 7 via a bearing. The rotating connecting bin 7 is located on the outer side of the stirring rod 4.

[0066] A centrifugal cleaning element is provided on the inner side of the rotating connecting bin 7 and is used to clean the highly viscous material on the stirring rod 4;

[0067] The heating and drying mechanism is provided at the bottom of the support plate 6 and is used to dry the viscous material inside the mixing tank 1;

[0068] The vibration separation member is provided on both sides of the support plate 6 and is used to discharge the material adhering to the inner wall of the mixing tank 1 and the stirring rod 4 after drying.

[0069] In this embodiment, the stirring of the material inside the stirring tank 1 is achieved by driving the stirring rod 4 to rotate clockwise by the driving motor 2. When the driving motor 2 drives the stirring rod 4 to rotate counterclockwise, the centrifugal cleaning part operates, and the heating and drying mechanism operates at the same time, so as to reduce the adhesion between the material and the stirring tank 1. Then, the material is separated from the inner wall of the stirring tank 1 through the synchronous operation of the vibration separation part, so that the material is discharged through the bottom of the stirring tank 1.

[0070] Example 2

[0071] Please refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 , centrifugal cleaning parts include:

[0072] The first ratchet 9 is provided on the outer wall of the rotating connecting bin 7 and is located above the support plate 6. The top of the support plate 6 is rotatably connected to a first pawl 12 that meshes with the first ratchet 9;

[0073] The second ratchet 26 is provided on the stirring rod 4 and is located inside the rotating connecting chamber 7;

[0074] The second pawl 28 is rotatably connected to the inner wall of the rotating connecting bin 7 via a rotating shaft and engages with the second ratchet 26;

[0075] The torsion spring 29 is engaged with the outer side of the rotating shaft connecting the rotating connecting bin 7 and the second pawl 28 through a slot. A torsion spring 29 is also provided between the first pawl 12 and the support plate 6 .

[0076] The orientation of the ratchet teeth on the second ratchet 26 is opposite to that of the ratchet teeth on the first ratchet 9 .

[0077] In this embodiment, when the driving motor 2 drives the stirring rod 4 to rotate clockwise, the first ratchet 9 is limited by the first pawl 12, so that the rotating connecting bin 7 cannot rotate with the stirring rod 4. During this process, the second ratchet 26 rotates synchronously with the stirring rod 4, and the second pawl 28 swings back and forth under the action of the second ratchet 26. When the driving motor 2 drives the stirring rod 4 to rotate counterclockwise, the second pawl 28 will block the second ratchet 26. At this time, the stirring rod 4 drives the rotating connecting bin 7 to rotate through the second ratchet 26 and the second pawl 28. In this way, the rotating connecting bin 7 can be driven to rotate when the stirring rod 4 rotates counterclockwise, so that the material on the surface of the stirring rod 4 is separated from the stirring rod 4 under the action of centrifugal force.

[0078] Example 3

[0079] Please refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 , the heating and drying mechanism includes:

[0080] The second transmission spur gear 27 is provided on the outer wall of the rotating connecting bin 7 and is located below the support plate 6;

[0081] The first transmission spur gear 25 is rotatably connected to the bottom of the support plate 6 and meshes with the second transmission spur gear 27. A shift pin 31 is installed at the bottom of the first transmission spur gear 25;

[0082] The directly connected sleeve plate 30 is sleeved on the outer side of the shift pin 31;

[0083] The air cylinder 23 is mounted on the bottom of the support plate 6 and is located on the side of the first transmission spur gear 25 away from the second transmission spur gear 27. A piston rod 32 is inserted into the interior of the air cylinder 23, and the piston rod 32 is connected to the outer wall of the direct-connection sleeve 30;

[0084] The traction frame 33 is provided at the bottom of the direct-connection sleeve 30, and a drying chamber 24 is provided at one end of the air cylinder 23 away from the direct-connection sleeve 30;

[0085] The bellows expansion tube 35 is provided at the bottom of the drying chamber 24 . One end of the bellows expansion tube 35 is connected to the air connection tube 34 . The traction frame 33 is connected to the outer wall of the air connection tube 34 .

[0086] The centrifugal contact unit is arranged on the top of the inner wall of the mixing tank 1 and is used to reduce the viscosity of the residual material in the mixing tank 1.

[0087] In this embodiment, when the rotating connecting bin 7 rotates synchronously with the stirring rod 4, the second transmission spur gear 27 will drive the first transmission spur gear 25 to rotate. At this time, the first transmission spur gear 25 will drive the direct-connection sleeve 30 to move back and forth left and right through the shift pin 31. When the piston rod 32 moves in the direction away from the air cylinder 23 as the direct-connection sleeve 30 moves, the centrifugal contact unit operates at the same time, which increases the temperature inside the mixing tank 1. The air cylinder 23 will absorb the hot air inside the mixing tank 1. In this process, The hot air inside the mixing tank 1 enters the air cylinder 23 through the connecting air pipe 34, the bellows expansion pipe 35, and the drying chamber 24. The humidity of the air inside the mixing tank 1 is reduced by the desiccant inside the drying chamber 24. When the piston rod 32 moves toward the air cylinder 23, the air inside the air cylinder 23 will be discharged from the air cylinder 23. At the same time, the position of the connecting air pipe 34 will also change with the movement of the direct-connected sleeve 30, so as to extract the hot air from different positions inside the mixing tank 1, thereby further improving the drying efficiency of the air inside the mixing tank 1.

[0088] Example 4

[0089] Please refer to Figure 2 、 Figure 3 、 Figure 4 , the centrifugal contact unit includes:

[0090] The guide plate 20 is mounted on the top of the rotating connecting bin 7. A transverse rod 19 is provided on one side of the guide plate 20 and extends to the other side of the guide plate 20. A first telescopic spring 21 connected to the guide plate 20 is provided on the end of the transverse rod 19 close to the stirring rod 4.

[0091] The extrusion rod 18 is rotatably connected to the end of the transverse rod 19 away from the stirring rod 4;

[0092] The rotating ring 14 is provided on the top of the extrusion rod 18 and is located outside the stirring rod 4;

[0094] A protective sleeve 8 is installed on the top of the inner wall of the mixing tank 1, and a heater 17 is installed inside the protective sleeve 8;

[0095] The second contact piece 16 is provided on the top of the positioning ring 13;

[0096] The connecting chamber 10 is installed on the top of the inner wall of the stirring tank 1 and is located on one side of the stirring rod 4. The second contact piece 16 is located on the inner side of the connecting chamber 10 and is connected to the positioning ring 13. The first contact piece 15 is installed on the inner wall of the connecting chamber 10.

[0097] The first contact piece 15 is electrically connected to the driving motor 2 through a wire, and the second contact piece 16 is electrically connected to the heater 17 through a wire.

[0098] The end of the extension frame 11 away from the positioning ring 13 is equal in size to the bottom of the protective sleeve 8 , and the protective sleeve 8 is a vacuum bottomless cylindrical structure.

[0099] In this embodiment, the rotation of the rotating connecting bin 7 causes the transverse rod 19 to move in a direction away from the stirring rod 4 under the action of centrifugal force. During this process, the transverse rod 19 pulls the rotating ring 14 downward through the extrusion rod 18, so that the second contact piece 16 contacts the first contact piece 15, thereby enabling the heater 17 to be powered on and operate. At the same time, the extension frame 11 will lose its cover on the bottom of the protective sleeve 8 as the positioning ring 13 moves downward. At this time, the heater 17 will heat the air inside the stirring tank 1, and at the same time, the hot air is dried by the drying bin 24, so that the moisture in the residual material inside the stirring tank 1 is reduced, thereby reducing the viscosity between the residual material and the stirring tank 1, so that the dried material is separated from the stirring tank 1, thereby achieving the self-cleaning effect of the equipment.

[0100] Example 5

[0101] Please refer to Figure 2 、 Figure 3 、 Figure 5 、 Figure 8 , vibration separation parts include:

[0102] The positioning frame 36 is installed on both sides of the support plate 6, and the bottom of the positioning frame 36 is rotatably connected to the transmission shaft 42 through a bearing;

[0103] The splicing pipe 5 is provided at the bottom of the rotating connecting bin 7, and the outer wall of the splicing pipe 5 is installed with a first transmission bevel gear 22;

[0104] The second transmission bevel gear 43 is provided at one end of the transmission shaft 42 close to the splicing pipe 5 and meshes with the first transmission bevel gear 22;

[0105] The half gear 39 is provided at the end of the transmission shaft 42 away from the second transmission bevel gear 43;

[0106] The guide frame 38 is provided on the outside of the positioning frame 36. A spur rack 44 is slidably connected to the guide frame 38. One end of the spur rack 44 is provided with a second telescopic spring 37 connected to the guide frame 38.

[0107] The pushing frame 40 is provided at one end of the spur rack 44 away from the second telescopic spring 37 , and a striking rod 41 is provided at the bottom of the pushing frame 40 .

[0108] When the end of the impact rod 41 away from the pushing frame 40 contacts the inner wall of the mixing tank 1, the second telescopic spring 37 is in an incompletely extended state. This structure ensures that the impact rod 41 is fully in contact with the inner wall of the mixing tank 1.

[0109] The impact rods 41 on both sides of the support plate 6 face in opposite directions. This structure is used to achieve synchronization of the impact rods 41 on both sides of the support plate 6 impacting the inner wall of the mixing tank 1 .

[0110] In this embodiment, when the rotating connecting bin 7 rotates, it will drive the splicing pipe 5 to rotate. At this time, the splicing pipe 5 drives the second transmission bevel gear 43 to rotate through the first transmission bevel gear 22. When the second transmission bevel gear 43 rotates, the transmission shaft 42 will drive the half gear 39 to rotate. The straight rack 44 moves during the rotation of the half gear 39. At the same time, the impact rod 41 will move with the pushing frame 40 in the direction away from the inner wall of the mixing tank 1. When the locking teeth on the half gear 39 are separated from the straight rack 44, the straight rack 44 will quickly recover under the action of the elastic restoring force of the second telescopic spring 37, so that the impact rod 41 will hit the inner wall of the mixing tank 1, thereby causing the mixing tank 1 to vibrate as a whole, thereby improving the separation effect of the dried material and the mixing tank 1, and further improving the self-cleaning efficiency of the equipment.

[0111] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
