Description

Technical Field

[0001] The invention relates to the technical field of reactors, and in particular to a reactor for producing modified asphalt and a production process thereof. Background Art

[0002] In the production process of modified asphalt, the reactor, as one of the key equipment, undertakes the task of mixing, reacting and homogenizing the base asphalt with various modifiers. However, there are some technical problems in the feeding link of the traditional reactor for modified asphalt production, which affects the production efficiency and product quality. First, the problem of accurate metering and feeding. The traditional feeding method often relies on manual operation, and the feeding amount is estimated by weighing or volumetric method, which is not only time-consuming and labor-intensive, but also difficult to achieve accurate metering. The inaccurate feeding amount will lead to an imbalance in the ratio of modifier to base asphalt, which in turn affects the performance and quality of modified asphalt. Secondly, it is limited to adapt to a variety of modifiers. There are many types of modifiers used in the production process of modified asphalt, including polymers, rubber powder, sulfur, etc., and their density, particle size and feeding requirements are different.

In the traditional reactor feeding process, manual intervention is an indispensable link, which not only increases the operator's workload and safety risks, but also limits the improvement of production efficiency.

[0024] A reaction kettle for modified asphalt production in the present invention comprises a kettle body 1. A plurality of temporary storage barrels 2 are arranged on the inner wall of the kettle body 1, and these temporary storage barrels 2 are used to temporarily store materials to be added to the reaction. A feed pipe 3 is installed on the top of each temporary storage barrel 2, and these feed pipes 3 penetrate to the top of the kettle body 1 and are connected to the top of the kettle body 1, so that the material can be added from the top. A movable baffle plate 4 is installed on the inner wall of the temporary storage barrel 2, and a discharge pipe 41 is connected to the bottom of the baffle plate 4. The baffle plate 4 is concavely arranged and the concave part faces the discharge pipe 41. A valve 42 is installed on the surface of the discharge pipe 41 to control the outflow of materials.

In addition, a mounting cylinder 13 is also installed on the inner top wall of the kettle body 1. The surface of the mounting cylinder 13 is provided with contact switch 3 14 and contact switch 4 15. These two switches cooperate with contact probe 2 46 at the end of U-shaped rod 2 45 at the bottom of the baffle plate 4 to control the switch state of valve 1 31 on the surface of the feed pipe 3. Through the above structure, the amount of material added to the reactor each time can be accurately controlled to ensure the stability and accuracy of the production process. The driving member 9 includes a mounting plate 91 installed on the inner wall of the kettle body 1. The mounting plate 91 is rotatably connected with a rotating rod 1 92 through a bearing. A rotating rod 2 93 is installed at the bottom of the driving rod 5. The rotating rod 2 93 and the rotating rod 1 92 are meshed and connected through a bevel gear. A toothed disc 94 is installed at the end of the rotating rod 1 92, and a rack portion 95 is installed at the bottom of the contact probe 1 44. When the rack portion 95 moves upward, it will drive the toothed disc 94 to rotate, and then drive the rotating rod 1 92 and the rotating rod 2 93 to rotate, so that the driving rod 5 and the feed hopper 8 rotate to the position of the next temporary storage bucket 2. When the rack portion 95 moves downward, it will not drive the toothed disc 94 to rotate. This driving method realizes the automatic positioning and rotation of the feed hopper 8, and improves the automation degree and production efficiency of the equipment.

[0025] In the present invention, the rack part 95 includes a straight plate 951 installed at the bottom of the contact probe 44, and a plurality of latch teeth 952 are arranged on the side of the straight plate 951. The ends of these latch teeth 952 are rotatably connected to the straight plate 951 through a rotating shaft, so that the latch teeth 952 can rotate smoothly and drive the toothed disc 94 to rotate when driven by the toothed disc 94. At the same time, a limit bar 953 is also installed at the bottom of the latch teeth 952 to limit the latch teeth 952 and prevent them from rotating by themselves when not subjected to force. The design of the rack part 95 makes its cooperation with the toothed disc 94 more stable and reliable, and improves the operating accuracy and stability of the equipment. When in use, when the straight plate 951 moves upward, its moving distance is just enough to drive the rotating rod 92 to rotate 90 degrees.

[0026] In the present invention, a leakage hose 81 is installed at the bottom of the feed hopper 8, and the leakage hose 81 is inserted into the feed pipe 3. At the same time, an arc-shaped limit plate 32 is provided on the surface of the feed pipe 3 on one side of the rotation direction, which is used to limit the leakage hose 81. The setting of the leakage hose 81 and the arc-shaped limit plate 32 ensures that the material can accurately flow from the feed hopper 8 into the corresponding temporary storage barrel 2, avoiding waste and pollution of the material.

[0027] A production process of a reactor for producing modified asphalt, including a reactor for producing modified asphalt, including the following steps: the material enters the temporary storage barrel 2 from the feed pipe 3, and as the material continues to increase, the baffle plate 4 is forced to move downward. When the baffle plate 4 moves to the bottom, the contact probe 1 44 contacts the contact switch 2 12, and the contact probe 2 46 contacts the contact switch 4 15. At this time, the valve 2 42 is opened and the valve 1 31 is closed, and the material is discharged from the discharge pipe 41 into the kettle body 1. After the material at the top of the baffle plate 4 is discharged, due to the gradual decrease in the weight of the material, the baffle plate 4 is reset upward under the pull of the weight 7. During the reset process, the contact probe 2 46 contacts the contact switch 3 14, and the valve 1 31 at the next location is opened. At the same time, the contact probe 1 44 contacts the contact switch 1 11, and the valve 2 42 is closed. If different weights of materials need to be added, the pulling force on the baffle plate 4 can be adjusted by replacing the weight 7. Through the above production process, the precise feeding and control of the reactor for modified asphalt production can be achieved, ensuring the stability of the production process and product quality, ensuring that all temporary storage barrels 2 are empty, the baffle plate 4 is in the initial position, the contact probe 1 44 is in contact with the contact switch 1 11, and the valve 2 42 is closed; the contact probe 2 46 is in contact with the contact switch 3 14 or is in the initial untriggered state, depending on the design logic, and the valve 1 31 is in an open or closed state depending on whether the current feeding is required. The weight 7 has been installed on the suspension rope 6 according to the weight of the required feeding. The operator pours the material into the feed hopper 8, and the material enters the feed pipe 3 of the currently selected temporary storage barrel 2 through the leakage hose 81. As the material increases, the baffle plate 4 gradually descends, driving the U-shaped rod 1 43 and the contact probe 1 44 to descend, and the U-shaped rod 2 45 and the contact probe 2 46 to descend. When the baffle plate 4 drops to a certain extent, the contact probe 1 44 moves from the contact switch 1 11 to the contact switch 2 12, triggering a signal to open the valve 2 42. At the same time, the contact probe 2 46 drops to a position where it contacts the contact switch 4 15 or reaches a certain preset distance, triggering a signal, causing the valve 1 31 to close and stop feeding the current temporary storage barrel 2. The material is discharged from the opened valve 2 42 through the discharge pipe 41 into the kettle body 1. Baffle plate reset and next cycle: as the material is discharged, the baffle plate 4 gradually rises under the pulling force of the weight 7 due to the reduction in weight. When the baffle plate 4 rises to a certain position, the contact probe 44 contacts the contact switch 11 again, triggering a signal to close the valve 2 42. At the same time, the contact probe 46 rises to contact the contact switch 3 14 or reaches a preset position to trigger a signal. If the system is set to automatic cycle, the valve 1 31 is opened to prepare for the addition of the next temporary storage bucket 2. At this time, if there is a driving member 9 in the system to control the rotation of the feed hopper 8, the interaction between the rack portion 95 and the toothed disc 94 will cause the driving rod 5 and the feed hopper 8 to rotate to the position of the next temporary storage bucket 2. Repeat steps 2 to 4 until all temporary storage buckets 2 have been filled according to the predetermined amount, or until the total amount required for production is reached.When all materials have been added to the kettle body 1 and the reaction has started, the feeding system can be closed and the subsequent production process can be carried out. After the production is completed, the reactor and the temporary storage barrel 2 are cleaned as needed to prepare for the next production.
