[0022] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:
[0023] like Figures 1 to 4 As shown, a burner for asphalt production includes a frame, a feeding mechanism 3, a heating cylinder 2 and a driving mechanism 4. The heating cylinder 2 is provided on the top of the frame, the feeding mechanism 3 is provided at the feeding end 21 of the heating cylinder 2, the other end of the heating cylinder 2 is provided with a discharging end 22, and the driving mechanism 4 is provided at the bottom of the heating cylinder 2. The feeding mechanism 3 and the driving mechanism 4 are both fixedly connected to the frame.
[0024] The outer surface of the heating cylinder 2 is provided with a coil 5, and the coil 5 includes a heating coil 51 and a heat preservation coil 52. The heating coil 51 is provided on one side of the feed end 21, and the heat preservation coil 52 is provided on one side of the discharge end 22. The heating cylinder 2 is heated by the coil 5 so that the asphalt component in the heating cylinder 2 is heated evenly. The winding density of the heating coil 51 is greater than the winding density of the heat preservation coil 52, so that the heating capacity of the heating coil 51 is stronger than that of the heat preservation coil 52. The asphalt component heats up rapidly and is stirred in the heating coil 51 section, and remains in a constant stable range and continues to be stirred evenly in the heat preservation coil 52 section. The external circuits of the heating coil 51 and the heat preservation coil 52 are independent of each other, and the current intensity can be set separately without interfering with each other. The inner wall of the heating cylinder 2 is provided with a spiral blade 23. Driven by the spiral blade 23, the asphalt component inside the heating cylinder 2 is transferred from the feed end 21 to the discharge end 22. An outer sprocket 43 cooperating with the driving mechanism 4 is provided on the outer surface of the heating cylinder 2. The driving mechanism 4 drives the heating cylinder 2 to rotate, so that the asphalt components in the heating cylinder 2 are heated and stirred at the same time.
[0025] The driving mechanism 4 includes a rotating motor 41 and a chain 42. The rotating motor 41 is fixedly connected to the second platform 12 on the frame. The output end of the rotating motor 41 is provided with a driving sprocket, which is connected to an outer sprocket 43 through the chain 42. When the rotating motor 41 is started, the rotating motor 41 drives the driving sprocket to rotate, the driving sprocket drives the outer sprocket 43 to rotate through the chain 42, and the outer sprocket 43 drives the heating cylinder 2 to rotate.
[0026] Both ends of the heating cylinder 2 are provided with annular grooves 25, and both ends of the frame are provided with rollers 15 that match the annular grooves 25. The frame rolls in contact with the heating cylinder 2 through the rollers 15, reducing the friction between the heating cylinder 2 and the frame, and fixing the axial position of the heating cylinder 2. The feed end 21 and the discharge end 22 are both conical, and the conical feed port 34 facilitates the various components of the asphalt to enter the heating cylinder 2, and the conical discharge end 22 facilitates the collection of the stirred asphalt and discharges the asphalt. The outer surface of the heating cylinder 2 is provided with a thermal insulation layer 26, and the thermal insulation layer 26 is a thermal insulation material. The thermal insulation layer 26 is used to prevent the heat inside the heating cylinder 2 from dissipating, saving energy consumption. A front column 13 is provided at one end of the frame close to the feed end 21, and a rear column 14 is provided at one end close to the discharge end 22. The height of the front column 13 is higher than the height of the rear column 14. The height of the feed end 21 is higher than the height of the discharge end 22, which is more conducive to discharging the material from the heating cylinder 2. The discharge end 22 is provided with a rear cover 24, one side of the rear cover 24 is connected to the discharge end 22 by a hinge, and the other side is provided with a buckle 241. The discharge end 22 is provided with a card interface 242 that matches the buckle 241, and the rear cover 24 is provided with a handle 243. During the heating and stirring process, the rear cover 24 is locked with the discharge end 22 by the cooperation of the buckle 241 and the card interface 242. When it is necessary to discharge the asphalt, the rear cover 24 is opened by controlling the handle 243, the heating cylinder 2 continues to rotate, and the stirred asphalt is discharged from the discharge end 22.
[0027] A first platform 11 is provided on one side of the frame near the feeding end 21, and the feeding mechanism 3 is fixedly connected to the frame through the first platform 11. The feeding mechanism 3 includes a feeding motor, a feeding pipe 31 and a silo 33. One end of the feeding pipe 31 extends into the feeding end 21, and the other end is provided with a feeding motor, and the middle part is connected with the silo 33. The output end of the motor is arranged inside the feeding pipe 31 and is provided with a spiral shaft 321; the silo 33 is provided with a feeding port 34. The material enters the silo 33 from the feeding port 34 and falls into the feeding pipe 31. Start the feeding motor, and the spiral shaft 321 rotates, so that the material enters the heating cylinder 2. According to the actual production situation, the speed of the feeding motor can be controlled to control the feeding rate. A plurality of feeding ports 34 are provided above the silo 33, and the diameters of the feeding ports 34 are different. The proportions of the various components of the asphalt mixture are different. By changing the diameters of the various feed ports 34 in a certain proportion, the flow rates of the various asphalt components entering the heating cylinder 2 are in a certain proportional relationship, thereby better controlling the proportions of the various asphalt components added.
[0028] The working principle of the specific implementation of the utility model is as follows: the feeding motor is started, the material is transferred from the feeding mechanism 3 to the heating cylinder 2, the rotating motor 41 drives the heating cylinder 2 to rotate, and the coil 5 heats the heating cylinder 2. The material is continuously heated and stirred inside the heating cylinder 2, and under the action of the spiral blade 23, the material moves from the feeding end 21 to the discharging end 22.
