Description

Technical Field

[0001] This utility model relates to the field of asphalt production equipment technology, and in particular to an emulsification device for asphalt production. Background Technology

[0002] Emulsified asphalt refers to an oil-in-water emulsion formed by heating and melting asphalt, and then dispersing it as fine particles in an aqueous solution containing emulsifiers and their additives under mechanical stirring.

[0003] Chinese Patent No. CN217042117U discloses a heating emulsification device for asphalt production, relating to the field of asphalt production. This heating emulsification device includes a shell, an emulsification cylinder, and a servo motor. A convex ring is fixedly welded to the upper end of the emulsification cylinder, and an annular slider is slidably connected to the convex ring. Scrapers are fixedly installed on both the left and right sides of the lower end of the annular slider. A driven gear is fixedly welded to the outer wall of the annular slider. A reduction motor is fixedly installed on the left side of the upper surface of the shell, and a drive gear is fixedly installed at the lower end of the output shaft of the reduction motor. Through the interaction of the reduction motor, drive gear, driven gear, annular slider, and scrapers, this heating emulsification device allows the scrapers to rotate on the inner wall of the emulsification cylinder, thereby scraping off the emulsified asphalt adhering to the inner wall of the cylinder. This saves manpower for manual cleaning, improves work efficiency, and has better practicality, meeting the needs of users.

[0004] However, the above technical solution has the following shortcomings: when the emulsified asphalt flows out of the device, some of the emulsified asphalt will remain at the control valve, thus affecting the sealing of the control valve. After long-term use, water and asphalt will overflow from the gaps in advance, thus affecting the production efficiency and production cost of emulsified asphalt. Utility Model Content

[0018] Example 1

[0019] like Figures 1-3 As shown in this embodiment, an emulsification device for asphalt production includes a base frame 1, a sleeve 5, and a top frame 6. The base frame 1 is equipped with a lifting assembly and a conveying assembly. The lifting assembly includes a hydraulic cylinder 14 mounted on the base frame 1 and a lifting frame 15 connected to the output end of the hydraulic cylinder 14. The conveying assembly includes a conveying frame 2 bolted to the base frame 1, a motor a3 mounted on the conveying frame 2, and a screw conveying rod 4 mounted on the output end of the motor a3. The sleeve 5 is detachably mounted on the top of the base frame 1, and a heating mechanism is provided on the sleeve 5 and the base frame 1. The top frame 6 is detachably mounted on the sleeve 5 and has a smoke outlet pipe 61 and a discharge cylinder 62. A mixing assembly is also provided on the base frame 1, the sleeve 5, and the top frame 6. The lifting frame 15 is inverted L-shaped, with its top surface gradually tilting away from the sleeve 5 to facilitate the asphalt sliding down to the conveying assembly under its own weight.

[0020] In this embodiment, the hydraulic cylinder 14 pushes the lifting frame 15 upward until the lifting frame 15, sleeve 5, and top frame 6 cooperate to form a sealed space. Then, the user pours asphalt, liquid, and catalyst into the sealed space through the discharge cylinder 62. The mixing component mixes the asphalt until it emulsifies. The hydraulic cylinder 14 drives the lifting frame 15 downward. The asphalt slides down to the conveying component under the action of the mixing component and its own gravity. The motor a3 drives the screw conveyor 4 to convey the asphalt out of the sealed space. After the asphalt is conveyed, the hydraulic cylinder 14 pushes the lifting frame 15 to reset. Then, the user can remove the conveying component from the base frame 1 and clean the conveying component and the lifting frame 15. The residual asphalt on the conveying component can be recycled to reduce production damage to asphalt and ensure production efficiency.

[0021] Example 2

[0022] like Figure 1 and Figure 2As shown, this embodiment of the emulsification device for asphalt production, compared to Embodiment 1, includes a heating mechanism comprising two sets of heating components arranged opposite to each other on the sleeve 5 and the base frame 1. The heating components include a heat insulation frame 16 arranged on the sleeve 5 and the base frame 1, multiple abutment frames 17 arranged circumferentially on the heat insulation frame 16, a heating block 19 arranged on each of the multiple abutment frames 17, and a spring 18 arranged between each pair of abutment frames 17 and the heat insulation frame 16. The heat insulation frame 16, the abutment frames 17, and the heating blocks 19 are sequentially and electrically connected.

[0023] In this embodiment, the user places two heat insulation frames 16 opposite each other on the sleeve 5 and fixes them with bolts. Then, the spring 18 abuts the heating block 19 against the sleeve 5. The current from the power supply passes through the heat insulation frame 16, the abutment frame 17 and the heating block 19 in sequence, so that the heating block 19 dissipates heat. The heat insulation frame 16 reduces the rate of heat exchange with the outside air, reduces energy loss, and ensures the heating speed of the asphalt inside the solid heating sleeve 5 by heating the asphalt.

[0024] Example 3

[0025] like Figure 1 and Figure 3 As shown, this embodiment proposes an emulsification device for asphalt production. Compared to Embodiment 1, in this embodiment, the mixing assembly includes a motor b7 mounted on the top frame 6, a mixing frame detachably mounted on the sleeve 5, a drive rod 8 rotatably mounted on the mixing frame, a spiral conveying blade 9 mounted on the outer circumference of the drive rod 8, a rotating bearing 10 mounted on the base frame 1, a cleaning frame 11 mounted on the drive rod 8, an adjusting rod 131 slidably mounted on the cleaning frame 11, a cleaning plate 132 connected to the adjusting rod 131, and a guide cloth 12 disposed between the cleaning plate 132 and the cleaning frame 11; the rotating bearing 10 is connected to one end of the drive rod 8. A fixing knob is rotatably mounted on the cleaning frame 11, and the fixing knob is threadedly connected to the adjusting rod 131.

[0026] In this embodiment, the motor b7 abuts against the drive rod 8 to rotate on the mixing frame. The mixing frame is bolted to the sleeve 5. Before mixing, the user adjusts the position of the adjusting rod 131 according to the inner circumferential diameter of the sleeve 5, so that the cleaning plate 132 abuts against the inner surface of the sleeve, and the cleaning frame 11 slides against the top of the base frame 1. This allows the cleaning plate 132 and the cleaning frame 11 to clean the asphalt on the surface of the sleeve 5 and the base frame 1, thereby reducing asphalt production damage and reducing the difficulty of subsequent maintenance.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
