Description

TECHNICAL FIELD

[0001] The application relates to the technical field of modified asphalt preparation, and particularly relates to a biochar modified asphalt material preparation device and a preparation method thereof. BACKGROUND

[0002] In cities with rapid economic development, especially in cities with large traffic volume, the number of urban roads and bridges is large. By adding modified asphalt to road construction materials, the anti-aging and high-temperature performance can be greatly improved. Biochar can improve the performance of asphalt due to its carbon properties and forms. Rice husks, fruit shells and straws are abundant in raw material sources. Compared with pure rubber raw materials, biochar is more environmentally friendly and does not produce harmful substances. Biochar not only saves resources but also effectively protects the environment.

[0003] A modified asphalt preparation device is disclosed in a Chinese utility model patent with the publication number CN114082498A. The device includes a first modifier adding hopper, a second modifier adding hopper, a base asphalt mixing tank, an asphalt grinding tank, an asphalt dilution tank, and an asphalt storage tank. The base asphalt mixing tank is emptied after the asphalt mixture in the base asphalt mixing tank is completely transferred to the asphalt grinding tank through a colloid mill, and the next mixing process begins. At the same time, the asphalt mixture in the asphalt grinding tank is repeatedly ground for a period of time through the colloid mill. The grinding process produces high-concentration modified asphalt. After the mixing in the base asphalt mixing tank is completed, the base asphalt is injected into the asphalt dilution tank through the asphalt pump A. After the grinding in the asphalt grinding tank is completed, the high-concentration modified asphalt in the asphalt grinding tank is injected into the asphalt dilution tank through the colloid mill, and the base asphalt is fully stirred to become modified asphalt. The modified asphalt is output to the asphalt storage tank.

[0004] However, the preparation process lacks crushing and grinding of raw materials, which may result in excessively large particle sizes of the raw materials and affect the quality of the finished product after mixing. In addition, the device structure is complex, large and energy-consuming.

[0005] A modified asphalt preparation device for roads is disclosed in a Chinese utility model patent with the publication number CN211098974U. The device includes a kettle body, a main stirring shaft, 22 auxiliary stirring shafts, a heating device, an ultrasonic generator, and an anti-sticking layer. The kettle body is provided with a speed reducer at the top end, and the speed reducer is connected with a driving motor. The kettle body is provided with a feeding port at the top and an outlet at the bottom. The main stirring shaft is rotatably arranged in the kettle body and connected with the driving motor through the speed reducer. The auxiliary stirring shafts are rotatably arranged in the kettle body and driven by the main stirring shaft. The main stirring shaft and the auxiliary stirring shafts are both provided with a plurality of stirring blades. The heating device is installed on the side of the kettle body. The ultrasonic generator is connected with the side of the kettle body. The anti-sticking layer is arranged on the inner surface of the kettle body.

[0006] Although it improves the stirring mode, it lacks the screening function of raw materials, and cannot guarantee that the particle size of the raw materials meets the production requirements, affecting the quality of stirring and mixing. SUMMARY

When the carbonized biological raw material crushed by the rolling roller 531 slides to the falling section a14, the shaking plate 631 is driven by the servo motor d630 to shake the carbonized biological raw material, so that the carbonized biological raw material can fall more uniformly on the matrix asphalt mixed with the non-carbonized biological raw material in the material falling channel b42, and the shaking speed can be changed by calculation to make the carbonized biological raw material can be output according to the required proportion.

[0048] As shown in Figures 1 to 7 , a modified biological asphalt material preparation method includes the following steps:

[0049] S1. The biological raw material is carbonized by the carbonization furnace body 21 and transported to the raw material cylinder a1 by the conveying assembly 22, and the carbonized biological raw material in the raw material cylinder a1 falls into the material falling channel a11. The part of the biological raw material that needs to be carbonized is carbonized by the carbonization furnace body 21 and falls into the conveyor housing a220 through the receiving hopper a223, and then the carbonized biological raw material is transferred from the material falling hopper a227 to the raw material cylinder a1 by rotating the hinge dragon a222 driven by the servo motor a221, which has strong processing continuity, can closely combine the carbonization process with subsequent processing, and can improve processing efficiency.

[0050] S2. The biological raw material in the raw material cylinder b3 is crushed by the crushing assembly 51 and transmitted to the mixing hopper 41 by the transmission assembly 52, and the uncarbonized biological raw material is mixed with the matrix asphalt in the mixing hopper 41 in advance and falls into the material falling channel b42. The uncarbonized biological raw material output from the raw material cylinder b3 is crushed and ground by the counter-rotating crushing rollers a512 and b513 in the crushing assembly 51, and is sieved by the steel filter screen 518 provided to meet the preparation requirements of the uncarbonized biological raw material with a particle size of 200 purposes, thereby improving the quality of subsequent product preparation.

[0051] S3. The carbonized biological raw material transported in the material falling channel a11 is rolled by the rolling assembly 53. The carbonized biological raw material in the material falling channel a11 is crushed by the rolling assembly 53, so that the particle size of the carbonized biological raw material meets the preparation requirements of the particle size of 200 purposes, and the crushing assembly 51 can drive the rolling assembly 53 to crush the carbonized biological raw material while crushing the uncarbonized biological raw material, which is efficient and synchronized, and greatly saves energy.

[0052] S4. The carbonized biological raw material after rolling in the material falling channel a11 is shaken by the shaking assembly 63 to fall uniformly to the material falling channel b42. When the carbonized biological raw material crushed by the rolling roller 531 slides to the falling section a14, the shaking plate 631 shakes the carbonized biological raw material under the drive of the servo motor d630, so that the carbonized biological raw material falling from the material falling channel a11 to the material falling channel b42 can fall more uniformly on the matrix asphalt mixed with uncarbonized biological raw material, and the shaking speed can be changed by calculation to make the carbonized biological raw material output according to the required proportion.

[0053] S5. The matrix asphalt mixed with carbonized biological raw material and uncarbonized biological raw material is fully stirred with the modified additive in the additive cylinder 62 by the stirring assembly 61 and is output. The rotating shaft b612 in the stirring assembly 61 is driven by the servo motor c611 to rotate and fully stir by the arrayed stirring paddles 613, and is uniformly heated by the spiral heating pipe b617 to make the mixing effect better. Embodiment

[0054] As Figure 6 shown, wherein the same or corresponding parts as in Example One are denoted by the same reference numerals as in Example One, for the sake of brevity, only the differences from Example One will be described below; the difference between this Example Two and Example One is that an arc-shaped baffle 539 is fixedly arranged above the rolling roller 531. By arranging the arc-shaped baffle 539, the rolling roller 531 in front can be shielded, so as to avoid the un-rolled carbonized biological raw materials falling in the falling material channel a11 directly passing from above the rolling roller 531, affecting the quality of the finished product after subsequent mixing preparation.

[0055] When processing, the part of the biological raw material that needs to be carbonized is introduced into the carbonization furnace main body 21 through the feed hopper 24, the carbonization furnace main body 21 is carbonized and falls into the conveyor housing a220 through the receiving hopper a223, and then the carbonized biological raw material is transferred from the receiving hopper a227 to the raw material cylinder a1 by rotating the hinge a222 driven by the servo motor a221, and the carbonized biological raw material in the raw material cylinder a1 falls into the dropping channel a11 and automatically slides into the dropping channel b42, at the same time, the servo motor b511 drives the crushing roller a512 to rotate, and through the meshing of the driving gear a514 and the driven gear a515, the crushing roller b513 is driven to rotate synchronously, and the uncarbonized biological raw material output from the raw material cylinder b3 is crushed and ground by the opposite rotating crushing roller a512 and crushing roller b513, and the particle size of the raw material is set to 200 mesh, and the uncarbonized biological raw material after crushing that meets the particle size falls into the conveyor housing b520 through the steel filter screen 518 arranged at the bottom of the mounting seat 510, and the servo motor b511 drives the crushing roller a512 and the crushing roller b513 to rotate at the same time, and the hinge b521 is driven to rotate synchronously by the belt a523, and the uncarbonized biological raw material passing through the steel filter screen 518 is transferred to the mixing hopper 41 by the hinge b521 after falling into the conveyor housing b520, and is pre-mixed with the matrix asphalt, the connecting piece a516 on one side of the crushing roller b513 is connected with the connecting piece c534 through the belt b535, and when the crushing roller b513 rotates, the driving bevel gear 532 is driven to rotate through the belt b535, and the driving bevel gear 532 drives the driven bevel gear 533 meshing with it to rotate, and then the driving gear b536 arranged at the tail end of the driven bevel gear 533 cooperates with the driven gear b538 arranged at the tail end of the rotating shaft a537 to drive the crushing roller 531 to rotate and crush the carbonized biological raw material to obtain carbonized biological raw material with a particle size of 200 mesh, and when the carbonized biological raw material slides to the falling section a14, the shaking plate 631 shakes the carbonized biological raw material under the drive of the servo motor d630, so that the carbonized biological raw material uniformly falls on the matrix asphalt mixed with the uncarbonized biological raw material, and the carbonized biological raw material, the uncarbonized biological raw material and the matrix asphalt are pre-mixed and then introduced into the stirring cylinder 610 through the falling section b45, and the modifier additive in the modifier additive cylinder 62 is sucked into the stirring cylinder 610 by the suction pump 616, and the stirring paddle 613 is driven to rotate by the servo motor c611 to drive the rotating shaft b612 to rotate, so that the stirring paddle 613 fully stirs each raw material in the stirring cylinder 610 to obtain modified asphalt, and the modified asphalt is output through the discharge port 614.
