Description

Technical Field

[0001] This invention belongs to the field of asphalt production auxiliary material feeding technology, specifically an auxiliary material feeding device for asphalt production. Background Technology

[0002] During the asphalt production process, auxiliary materials need to be added during the mixing process. The added auxiliary materials, especially lightweight powders such as rubber powder, have a significantly lower density than asphalt and poor wettability and compatibility with asphalt. Lightweight powders such as rubber powder have small particles, large specific surface area, and strong hygroscopicity. During storage and transportation, they are prone to agglomeration, caking, and clumping due to moisture, electrostatic adsorption, or compression.

[0003] Compared with the existing patent 1: Authorization Announcement No. CN116440776B, this device only achieves mixing by splashing and stirring, and does not have the functions of forced pressure immersion and local stirring. It cannot press lightweight powders such as rubber powder with a density much lower than asphalt into the interior of asphalt. The auxiliary materials are still easy to float on the surface of asphalt and are difficult to wet and fuse, resulting in poor overall mixing uniformity. In summary, existing technologies for processing rubber powder additives generally suffer from poor anti-caking effects, easy clogging during feeding, difficulty in integration when floating on the asphalt surface, and uneven dispersion. There is an urgent need for an asphalt production additive feeding device that integrates anti-caking treatment, precise feeding control, and efficient wetting and mixing functions to solve the above-mentioned technical problems.

[0015] The beneficial effects of this invention are as follows: 4. This invention provides power to the drive component through an anti-caking component. The anti-caking component enables the crushing, breaking, and centrifugal dispersion of lightweight powdered materials such as rubber powder. The drive component can drive the feeding component to prevent material accumulation on the inner wall. The anti-caking component and the feeding component work together to achieve the effect of breaking arches and solving the problem of material arching during feeding. At the same time, the anti-caking component can also drive the extrusion rotary feeding component to rotate, thereby initiating the local mixing and mixing effect. Meanwhile, the drive component can control the extrusion rotary feeding component to descend and extrude the asphalt surface, effectively preventing lightweight powdered materials such as rubber powder from floating on the asphalt surface after entering the asphalt.

[0016] 2. This invention, through the cooperation of various components of the anti-caking assembly, can achieve the crushing and dispersing of lightweight powdered additives such as rubber powder, preventing agglomeration, caking, and clumping before addition, which would lead to uneven performance of the mixture and affect the overall production quality and use effect of asphalt.

[0017] 3. This invention uses a grinding roller to drive a cross-shaped rotating rod to rotate. The rotation of the cross-shaped rotating rod disperses the material at the lower conical discharge hole of the storage bin, preventing arching during material discharge and solving the problem of arching. A drive assembly further drives the auxiliary discharge rod to rise and fall, effectively preventing material from adhering to the inner wall of the storage bin and solving the problem of material accumulation on the inner wall. 4. This invention, through the combination of various parts of the extrusion-rotation dispensing component and the drive component, enables multiple downward-pressing rotating blades to be driven downward and open. When the downward-pressing rotating blades move downward, they can compress lightweight powdered additives such as rubber powder falling on the asphalt surface into the interior of the asphalt, effectively preventing them from floating on the asphalt surface and being unable to mix further. The opening of the downward-pressing rotating blades allows for the dispensing of additives through the rotating connecting pipe. Through the combination of various parts of the extrusion-rotation dispensing component and the anti-caking component, multiple downward-pressing rotating blades can be driven to rotate. Through the setting of downward pressure and rotation, lightweight powdered additives can be extruded and locally stirred, further solving the problem that lightweight powdered additives such as rubber powder are difficult to disperse and blend quickly after entering the asphalt.

[0035] Working principle and usage process: When lightweight powdered additives such as rubber powder are required, since their density is significantly lower than that of asphalt and their wettability and compatibility with asphalt are poor, the rubber powder must first be poured into the storage hopper 209, and then the dual-axis servo motor 103 is started. The upper and lower output shafts of the dual-axis servo motor 103 rotate simultaneously. The upper output shaft drives the grinding roller 104 to rotate, and the grinding roller 104 drives the rotating connecting block 205, which is slidably connected to the upper end, to rotate. The rotation of the rotating connecting block 205 disperses the material at the lower outlet of the storage hopper 209, effectively solving the problem of rubber powder arching and being difficult to discharge. The lower output shaft of the dual-axis servo motor 103 rotates, driving the hinge shaft 105, which is fixedly connected to it, to rotate. The hinge shaft 105 then drives the driven rod 106, which is fixedly connected to one end, to rotate. Since one end of the driven rod 106 is hinged to the fixed block 411, and the fixed block 411 is fixedly connected to the sliding limit block 410, which is slidably connected to the mounting housing 401, the rotation of the hinge shaft 105 drives the driven rod 106 to reciprocate. The reciprocating motion of the driven rod 106 drives the sliding limit block 410 to reciprocate inside the mounting housing 401. Sliding, therefore the fixed block 411 drives the lead screw 412 to reciprocate. Through the connection between the lead screw 412 and the screw sleeve, the circular meshing active block 415 is driven to rotate. When the rack 407 needs to be raised or lowered, the hydraulic telescopic rod 403 is activated to retract backward, which drives the circular meshing driven block 406 to mesh with the circular meshing active block 415, thus completing the rotation of the gear 405. The rotation of the gear 405 drives the rack 407 to rise or fall. The rise or fall of the rack 407 drives the upper support rod 408 and the lower support rod 409, which are fixedly connected at both ends, to rise or fall. When the upper support rod 408 moves up and down, it drives the C-shaped connecting piece 203 to move up and down. The C-shaped connecting piece 203 moves up and down, which drives the limiting sealing ring 204 to move up and down. The limiting sealing ring 204 drives the auxiliary feeding rod 206 fixedly connected at the upper end to move up and down. By moving the auxiliary feeding rod 206 up and down, the rubber powder inside the storage barrel 209 is loosened, thereby preventing the rubber powder from accumulating on the edge of the storage barrel 209. When the driven rod 106 reciprocates, it drives the connecting rod 107, which is rotatably connected to the lower end, to rotate. The lower end of the connecting rod 107 is fixedly connected to the connecting shaft 110. The connecting shaft 110 drives the rotating dispersion chamber 108, which is connected to the lower end, to rotate. The rotation of the rotating dispersion chamber 108 drives the multiple rotating rings 111, which are fixedly connected to it, to rotate. When the rubber powder is poured in from top to bottom, it first passes through the middle of the grinding roller 104. The grinding roller 104 crushes the lumps in the rubber powder by squeezing it against the inner wall of the main body shell 101. Then it falls into the interior of the rotating dispersion chamber 108. The upper end of the rotating ring 111 inside the rotating dispersion chamber 108 is set with an inclined surface and has an inclined groove, which can rotate and shake the rubber powder to achieve crushing and shaking pretreatment and improve the subsequent mixing efficiency. When the rotating dispersion chamber 108 rotates, it drives the rotating connecting pipe 301, which is fixedly connected to the lower end, to rotate. The rotation of the rotating connecting pipe 301 drives the sliding circular limiting ring 302, which is slidably connected to the middle part, to rotate. Because multiple sliding protrusions are fixedly connected inside the sliding circular limiting ring 302, and the sliding protrusions are slidably connected to the sliding recess in the middle part of the rotating connecting pipe 301, it can slide when moving up and down, and can follow the rotation when rotating left and right. The rotation of the rotating connecting pipe 301 drives the sliding circular limiting ring 302 and the sliding mounting ring 303 to rotate. The rotation of the sliding mounting ring 303 drives the multiple downward-pressing rotating blades 304, which are hinged to the middle part, to rotate. Through the rotation of multiple extrusion protrusions 305 in the middle of the downward-pressing rotating blades 304, the downward-pressing rotating blades 304 begin to rotate after being extruded downwards, which plays a role in locally pressing and stirring the rubber powder. The rack 40 When the lower support rod 409, which is fixedly connected to the lower end, moves downward, it drives the upper support rod 408 to move downward. The upper support rod 408 drives the sliding circular limit ring 302 to move downward. The sliding circular limit ring 302 drives multiple hinge rods 307, which are fixedly connected to the lower end, to move downward. The downward movement of the hinge rods 307 drives the hinge plate 306, which is hinged to the lower end, to move downward. The hinge plate 306 drives the downward-pressing rotating blade 304 at the lower end, thereby squeezing the rubber powder placed above the asphalt downward. At the same time, with the setting of multiple extrusion protrusions 305, more rubber powder can be squeezed into the asphalt during downward extrusion. Since the density of rubber powder, a lightweight powder auxiliary material, is significantly lower than that of asphalt, its wettability and compatibility with asphalt are poor. Downward extrusion can effectively prevent the rubber powder auxiliary material from floating on the asphalt surface after entering the asphalt.
