Technical Field

[0001] The utility model relates to the technical field of initiator addition, in particular to an adjustable initiator quantitative addition device applicable to chemical production. Background Technique

[0002] Initiators, also known as free radical initiators in English, refer to a class of compounds that are easily decomposed into free radicals by heat. They can be used to initiate the free radical polymerization and copolymerization reactions of vinyl and diene monomers, and can also be used for the crosslinking and curing of unsaturated polyesters and polymer crosslinking reactions. There are many types of initiators, and the commonly used ones in adhesives are free radical initiators.

When in use, the storage tank 1 stores the initiator, and the stirring assembly 6 stirs the initiator. When the initiator needs to be added, the initiator flows under the drive of the water pump inside the device. The initiator flows downward to the discharge assembly 2, and the initiator flows along the discharge assembly 2 into the discharge pipe 3. The initiator flows along the discharge pipe 3 to the addition pipeline 5, and then flows along the addition pipeline 5 into the reaction tank. The refluxed initiator flows back to the storage tank 1 along the reflux pipeline 4. The newly added flowmeter 7 detects the flow rate of the refluxed initiator. The pressure regulating valve 8 on the initiator reflux pipeline 4 is used to control the addition amount of the initiator in real time. By setting the newly added flowmeter 7 and the pressure regulating valve 8 on the initiator reflux pipeline 4, the addition device can accurately measure and control the addition amount of the initiator by detecting the initiator flow rates on the discharge pipe 3 and the reflux pipeline 4, improving the metering accuracy, thereby reducing the error between the added value and the set value.

The scraping component 66 scrapes the materials adhered to the inner wall of the storage tank 1. The flow-around component 65 drives the initiator below to move upward. Through the scraping component 66 and the flow-around component 65, the initiator at the bottom and on the side wall is driven to flow, making the stirring of the stirring assembly 6 more uniform and improving the stirring effect of the initiator.

[0026] The flow-around component 65 includes a spiral rod 651. The inner side of the spiral rod 651 is fixedly connected to the outer side of the rotating shaft 62.

The bottom of the fixing plate 653 is fixedly connected to the bottom of the inner cavity of the storage tank 1. When in use, the rotating shaft 62 rotates to drive the flow-around component 65 to rotate. The spiral rod 651 in the flow-around component 65 drives the initiator at the bottom to flow. The initiator at the bottom bypasses the fixing plate 653 and flows into the guiding column 652, and then flows upward along the guiding column 652. By driving the initiator at the bottom to flow upward through the flow-around component 65, the stirring rod 64 can stir the initiator at the bottom, avoiding the inability to stir the initiator at the bottom and improving the stirring effect.

[0027] The scraping component 66 includes a rotating rod 661. A resilient spring 662 is fixedly connected to the inner side of the rotating rod 661. One end of the resilient spring 662 away from the rotating rod 661 is fixedly connected to a scraping plate 663. The outer side of the scraping plate 663 is slidably connected to the inner side of the rotating rod 661.

The scraping plate 663 is subjected to the reaction force of the storage tank 1, driving the resilient spring 662 to compress. Under the influence of its own elastic force, the resilient spring 662 drives the scraping plate 663 to adhere to the inside of the storage tank 1. The scraping plate 663 scrapes the materials adhered to the inner wall of the storage tank 1.

The rotating shaft 62 drives the connecting rod 63 to rotate. The connecting rod 63 drives the stirring rod 64 to rotate. The connecting rod 63 and the stirring rod 64 stir the initiator. The rotating shaft 62 rotates to drive the flow-around component 65 to rotate. The spiral rod 651 in the flow-around component 65 drives the initiator at the bottom to flow. The initiator at the bottom bypasses the fixing plate 653 and flows into the guiding column 652, and then flows upward along the guiding column 652. The initiator at the bottom flows to the stirring rod 64 and is stirred by the stirring rod 64;

[0030] At the same time, the rotating shaft 62 drives the rotating rod 661 in the scraping component 66 to rotate. The rotating rod 661 drives the resilient spring 662 and the scraping plate 663 to rotate. The scraping plate 663 is subjected to the reaction force of the storage tank 1, driving the resilient spring 662 to compress. Under the influence of its own elastic force, the resilient spring 662 drives the scraping plate 663 to adhere to the inside of the storage tank 1. The scraping plate 663 scrapes the materials adhered to the inner wall of the storage tank 1;

[0031] When an initiator needs to be added, the initiator flows under the drive of the water pump inside the device. The initiator flows downward to the discharge assembly 2, and the telescopic rod 22 drives the sliding block 23 to move upward. The initiator flows downward along the gap between the sliding block 23 and the guide plate 21. When the addition of the initiator stops, the telescopic rod 22 drives the sliding block 23 to move downward, and the sliding block 23 blocks the guide plate 21. The initiator flows downward into the discharge pipe 3, and the initiator flows along the discharge pipe 3 to the addition pipeline 5, and then flows along the addition pipeline 5 into the reaction tank. The refluxed initiator flows back to the storage tank 1 along the reflux pipeline 4. The newly added flowmeter 7 detects the flow rate of the refluxed initiator.
