Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of asphalt production, in particular to a special modified asphalt SBS submerged feeding system. Background Art
[0002] Composite modified asphalt combines the advantages of SBS modified asphalt and rubber asphalt. The modified rubber powder is evenly dispersed by high-speed shearing, grinding, stirring and other means, so that the rubber powder is fully dispersed in the matrix asphalt to form a stable suspension.

[0020] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0021] Reference Figure 1 The utility model embodiment provides a special modified asphalt SBS submerged feeding system, which includes: a large silo 1, a buffer bucket 2, a weighing meter 3, a metering bucket 4, a spiral pipe chain 5, a submerged feeder 6 and a premixing tank 7.
[0022] In this embodiment, the SBS modifier is delivered to the large silo 1 through the spiral tube chain 5, and the large silo 1 is also connected to the buffer hopper 2 through the spiral tube chain 5, and four weighing meters 3 are arranged below the buffer hopper 2. The buffer hopper 2 is connected to the metering hopper 4 through the spiral tube chain 5, and four weighing meters 3 are arranged below the metering hopper 4 to further calibrate the amount of the added special modified SBS. The metering hopper 4 is connected to the premixing tank 7 through the spiral tube chain 5, and the other end of the spiral tube chain 5 is connected to the submerged feeder 6 through a flexible unit.
[0023] Furthermore, by calculating the buoyancy of SBS in asphalt, the length of the submerged feeder 6 is set to 40 cm, thereby preventing the modifier from floating up and affecting the dissolution efficiency.
[0024] Furthermore, since the modifier is in granular form, the modifier is transported by the spiral tube chain 5 so that the modifier is in a mobile state, thereby preventing the modifier from accumulating into blocks and affecting transportation.
[0025] Furthermore, for the entire special modified asphalt SBS underwater feeding system, the closing of the feeding valve is controlled by PLC, and the metering information of the weighing sensor is displayed in real time on the central control screen through the corresponding communication method.
[0026] Working principle: Before adding SBS modifier, add material to the large silo to ensure sufficient modifier, set the amount of SBS to be added on the PLC control end, open the feed valve, add the material into the corresponding buffer hopper 2 through the spiral pipe chain 5, and feedback the weighing information in real time through the weighing module under the buffer hopper 2.
[0027] Open the feed valve of the metering hopper 4, and transport the material in the buffer hopper 2 to the metering hopper 4 through the spiral pipe chain 5. Complete the secondary metering through the weighing module under the metering hopper 4, and check the amount of material added. When the quantity calibration is completed, transport the material in the metering hopper 4 to the premixing tank 7 through the inclined spiral pipe chain 5. The end of the inclined spiral pipe chain 5 is connected with a pressing screw, and the end of the pressing screw is connected to a submersible feeder 6. The material is directly transported to the interior of the asphalt through the submersible feeder 6 to avoid the modifier floating on the surface of the asphalt and complete the full dissolution of the modifier.
