In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0023] In view of the problems existing in the prior art in the background art, the embodiments of the present application provide a solid waste fiber modified asphalt preparation device, such asFigures 1 to 2 Schematically shows a structural diagram of a solid waste fiber modified asphalt preparation device in an embodiment of the present application.

The dust treatment unit 4 includes a first dust collector 41 and a second dust collector 42. The first dust collector 41 is connected to the modifier processing unit 1, and the second dust collector 42 is connected to the screw agitator 3.
[0024] As Figures 1 to 2 , solid fiber waste refers to materials obtained by recycling and reprocessing fibrous solid waste. These materials usually come from the fiber components in industrial production, post-consumer products, construction waste, and other waste items, such as discarded clothes, plastic products, industrial gloves, etc. However, the quality of solid fiber waste varies. Therefore, in this embodiment, a modifier processing unit 1 is provided to pre-treat the above-mentioned solid fiber waste so that it can meet the standards as an asphalt modifier.
[0025] Specifically, the above-mentioned meter 24 is used to accurately measure and control the outflow rate of the modifier in the first hopper 21, improving the accuracy of the mixing ratio of the modified asphalt. The inlet of the feeder 23 is connected to the outlet of the first hopper 21, and is used to uniformly and continuously add the modifier to the screw agitator 3. The screw agitator 3 is used to fully mix the modifier with the matrix asphalt. Exemplarily, the feeder 23 can be selected from a screw conveyor, a vibrating feeder, a rotary feeder, etc. The present application does not limit the type of the feeder. Optionally, considering the flow characteristics of the fiber, in order to avoid blockage when the first hopper 21 discharges materials, the first hopper 21 can be connected with a vibrator or an air flow device to help the fiber discharge smoothly.
[0026] It should be understood that certain dust may be generated during the transportation of the modifier and the mixing of the asphalt and the modifier. In order to reduce the environmental pollution caused by the preparation of modified asphalt, in this embodiment, dust collectors are provided at multiple locations of the solid waste fiber modified asphalt preparation device. The first dust collector 41 is connected to the modifier processing unit 1, and the second dust collector 42 is connected to the screw mixer 3, thereby reducing the escape of dust. Further, the first dust collector 41 and the modifier processing unit 1 can be connected through an exhaust duct, and the second dust collector 42 and the screw mixer 3 can be connected through an exhaust duct or the second dust collector 42 can be integrated inside the screw mixer 3. As an example, the first dust collector 41 is set as a filtering brush, and the second dust collector 42 is set as a bag dust collector.
[0027] Thus, in the embodiment of the present application, through the modifier processing unit 1, the feeding unit 2, the screw mixer 3 and the dust treatment unit 4, the modifier processing unit 1 is used to preprocess the modifier, and the modifier includes solid fiber waste; the feeding unit 2 includes a first hopper 21 for storing the modifier, a second hopper 22 for storing matrix asphalt, and a feeder 23.

[0028] As an improvement of the present application to the above embodiment, in one implementation manner, the modifier processing unit 1 includes: a separator 11 and a crusher 12; the separator 11 is used to separate impurities contained in the input modifier, and the outlet of the separator 11 is connected to the inlet of the crusher 12; the crusher 12 is used to crush the modifier to a predetermined size.
[0029] Specifically, due to the uneven quality of the solid fiber waste, the above-mentioned separator 11 can separate the impurities in the solid fiber waste to ensure the purity and consistency of the solid fiber. The crusher 12 is used to crush the purified modifier to a predetermined size, making the modifier more uniform, which helps the modifier to form a uniform dispersed phase in the matrix asphalt, expand the contact area, and thus improve the utilization rate of the modifier.
[0030] Optionally, the separator 11 can be any one of a vibrating screen, an air separator, a cyclone separator, a centrifugal separator, a magnetic separator or an optical separator, etc.

Optionally, a first dust collector 41 can be arranged at the connection between the crusher 12 and the conveyor belt 13 to reduce the dust overflowing during the transfer of the modifier.
[0032] Based on the above embodiments, please continue to refer to Figure 1 , in one embodiment, the dust treatment unit 4 further includes a filter, and the filter is respectively connected to the first dust collector 41 and the second dust collector 42 for filtering the dust.
[0033] Specifically, compared with the dust collector, the filter generally has a finer filter screen / filter bag, which can capture the tiny particles that the dust collector cannot collect, thereby reducing the amount of dust discharged into the environment, reducing the blockage of the filter bag or filter screen inside the dust collector, and improving the health of the operators and the working environment.
[0034] Based on the above embodiments, in one implementation, the screw agitator 3 is connected with a temperature controller 5, and the temperature controller 5 is used to monitor and adjust the mixing temperature in the screw agitator 3.
[0035] Specifically, the activities of asphalt and the modifier are affected by temperature. Too high or too low temperature may affect their chemical reaction rates and effects.

[0037] Specifically, in order to precisely control the mixing ratio of the modifier and the base asphalt and the temperature of the mixing reaction in this embodiment, a sensor 61, a controller 62, and an actuator 63 are provided in the control unit 6. During operation, the sensor 61 first collects the real-time data of the meter 24 and the temperature controller 5, including the feeding speed, feeding amount of the modifier, and the temperature of asphalt modification. The controller 62 analyzes this real-time data and generates control instructions according to the requirements of the modified asphalt preparation process, and issues them to the actuator 63. The actuator 63 receives the control instructions and adjusts the working states of the modifier processing unit 1, the feeding unit 2, the screw stirrer 3, and the dust treatment unit 4 according to the instructions, such as adjusting the rotation speed of the screw stirrer 3, the conveying speed of the conveyor belt 13 in the modifier processing unit 1, the sorting rules of the separator 11, and the crushing size of the crusher 12, etc. Thus, an efficient and stable modified asphalt preparation process is realized. Ensure the uniform mixing of asphalt and modifier and maintain an appropriate processing temperature.
[0038] Optionally, the controller 62 can be a PLC controller or a DCS control system.
