Description

Technical Field

[0001] This utility model belongs to the field of azobisisobutyronitrile (AIBN) stirring technology, specifically relating to a stirring device. Background Technology

[0002] Azobisisobutyronitrile (AIBN) is an organic compound that is a white crystalline or crystalline powder. It is a commonly used free radical initiator and is widely used in the field of polymer synthesis, such as in polymerization reactions to prepare various plastics, rubbers, and resins. When dissolving AIBN (AIBN is insoluble in water but soluble in organic solvents such as ethanol and toluene; in liquid-phase reactions, dissolution is a necessary step to introduce AIBN into the reaction system), a stirring device is required.

[0003] In the current technology, cleaning the azobisisobutyronitrile (AIOBR) stirring device requires manually adding water to the inside of the device to clean the AIOBR. However, AIOBR has a certain degree of toxicity, posing a certain safety hazard. Therefore, a technical measure is proposed to solve the problem of the current technology requiring manual water addition to clean the AIOBR, which involves manual cleaning and has certain safety hazards due to the toxicity of AIOBR.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This specific embodiment is a stirring device, the structural schematic diagram of which is shown below. Figure 1 , Figure 2 , Figure 3 As shown, the device includes a base plate 3 and a lid 9. A tank body 1 is mounted on the upper surface of the base plate 3. A sealing ring 6 is embedded in the upper part of the tank body 1. The tank body 1 is compatible with the lid 9. A slot 19 is provided inside the lid 9. The lid 9 has a first round hole 18 and a second round hole 20. The first round hole 18 and the second round hole 20 are symmetrically distributed. A cleaning component 2 is provided inside the lid 9. A discharge pipe 4 is installed through the lower part of the tank body 1. A valve 5 is provided on the discharge pipe 4. A body 7 is connected to the side of the base plate 3. A sealing ring 6 is installed on the upper side of the body 7. The enclosure is equipped with a top plate 8. A second motor 13 is installed at the center of the upper surface of the top plate 8. The second motor 13 is connected to a screw 16. Two sets of symmetrically distributed limit rods 15 are installed on the lower surface of the top plate 8. The screw 16 is rotatably connected to the top plate 8 and threadedly connected to a lifting plate 14. The lifting plate 14 is slidably adapted to the limit rods 15. An installation plate 17 is installed at the center of the side of the lifting plate 14. A first motor 10 is installed on the upper surface of the installation plate 17. The first motor 10 is connected to a vertical rod 11, which rotates through the center of the enclosure cover. Position: Two sets of stirring blades 12 are installed at the lower end of the vertical rod 11. The tank cover 9 is fixedly installed on the lower surface of the mounting plate 17. When actually dissolving and stirring azobisisobutyronitrile powder, azobisisobutyronitrile and solvent (such as ethanol, toluene, etc.) are added according to the ratio. Then, the second motor 13 is started to drive the screw 16 to rotate. The rotation of the screw 16 drives the lifting plate 14 to move downward (when the lifting plate 14 moves downward, the limiting plate limits the lifting plate 14). The downward movement of the lifting plate 14 drives the mounting plate 17, the cleaning component 2, and the tank. The lid 9, the first motor 10, the vertical rod 11, and the stirring blade 12 move downwards. Then, the lid 9 engages with the tank body 1. The first motor 10 is then started to drive the vertical rod 11 to rotate. The rotation of the vertical rod 11 drives the stirring blade 12 to rotate. The rotation of the stirring blade 12 mixes and dissolves the azobisisobutyronitrile. During stirring, the sealing ring 6 increases the sealing performance. Then, the valve 5 is opened to discharge the azobisisobutyronitrile solution through the discharge pipe 4. When it is necessary to clean the tank body 1, the stirring blade 12, and the vertical rod 11, they are cleaned through the cleaning assembly 2.

[0029] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, the cleaning assembly 2 includes a multi-section electric telescopic rod 204, which is fixedly installed on the upper surface of the tank lid 9. The lower end of the multi-section electric telescopic rod 204 is adapted to the second round hole 20. A retaining ring 203 is connected to the lower end of the multi-section electric telescopic rod 204. Multiple sets of evenly distributed first water spray holes 205 are opened on the outside of the retaining ring 203, and multiple sets of evenly distributed second water spray holes 206 are opened inside the retaining ring 203. A vertical pipe 202 is installed on the upper surface of the retaining ring 203, and a telescopic hose 201 is installed on the upper end of the vertical pipe 202. The telescopic hose 201 is connected to an external water pipe. The vertical pipe 202 is slidably adapted to the first round hole 18, and the retaining ring 203 is properly engaged with the retaining groove 19. The first water spray hole 205 and the second water spray hole 206 are set at an angle and expand outward to supply water to the cleaning assembly through an external water source. Then, the multi-section electric telescopic rod 204 is activated to drive the retaining ring 203 to move downward. The downward movement of the retaining ring 203 drives the vertical pipe 202 and the telescopic hose 201 to move downward. When the retaining ring 203 moves, clean water enters the retaining ring 203 through the telescopic hose 201 and the vertical pipe 202 (the length of the vertical pipe 202 is greater than that of the tank 1). Then, the clean water cleans the tank 1, the stirring blades 12, and the vertical rod 11 through the first water spray hole 205 and the second water spray hole 206 of the retaining ring 203.

[0030] Working principle: When dissolving and stirring azobisisobutyronitrile powder, azobisisobutyronitrile and solvent (such as ethanol, toluene, etc.) are added according to the ratio. Then, the second motor 13 is started to drive the screw 16 to rotate. The rotation of the screw 16 drives the lifting plate 14 to move downward (the lifting plate 14 is limited by the limiting plate when it moves downward). The downward movement of the lifting plate 14 drives the mounting plate 17, cleaning component 2, tank cover 9, first motor 10, vertical rod 11, and stirring blade 12 to move downward. Then, the tank cover 9 engages with the tank body 1. Then, the first motor 10 is started to drive the vertical rod 11 to rotate. The rotation of the vertical rod 11 drives the stirring blade 12 to move downward. The stirring blade 12 rotates, mixing and dissolving azobisisobutyronitrile. During stirring, the sealing ring 6 increases the sealing performance. Then, the valve 5 is opened to discharge the azobisisobutyronitrile solution through the discharge pipe 4. When it is necessary to clean the tank 1, stirring blade 12, and vertical rod 11, cleaning is carried out through the cleaning assembly 2. The growth of the second motor 13, screw 16, lifting plate 14, mounting plate 17, and limit rod 15 facilitates the up and down movement of the tank cover 9, thereby facilitating the up and down movement of the stirring blade 12 and making it convenient for inspection and maintenance of the stirring blade 12. The sealing ring 6 increases the sealing performance.

[0031] The cleaning component 2 operates by supplying water to the cleaning assembly via an external water source. Then, the multi-section electric telescopic rod 204 is activated, causing the retaining ring 203 to move downwards. This downward movement of the retaining ring 203 causes the vertical pipe 202 and the telescopic hose 201 to move downwards. As the retaining ring 203 moves, clean water enters it through the telescopic hose 201 and the vertical pipe 202 (the vertical pipe 202 is longer than the tank 1). The clean water then cleans the tank 1, the stirring blades 12, and the vertical rod 11 through the first spray hole 205 and the second spray hole 206 of the retaining ring 203. 03 is at a certain distance from the inner wall of the tank 1 and the stirring blades 12. The first water spray hole 205 and the second water spray hole 206 are set to an inclined and expanded shape, so that the area sprayed by the first water spray hole 205 and the second water spray hole 206 is fan-shaped, which facilitates cleaning. During cleaning, the tank cover 9 is engaged with the tank 1. With the setting of the cleaning component 2, there is no need for manual contact with the azobisisobutyronitrile inside the tank 1, which improves safety and the cleaning speed is fast. The area sprayed by the first water spray hole 205 and the second water spray hole 206 is fan-shaped, and there are no dead corners in the cleaning, which improves practicality.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
