Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0049] Please see Figure 1This utility model provides an asphalt loading workshop, including a chamber 1, a roller shutter door (not shown in the figure) located on the front side of the chamber 1, a material feeding assembly 3 located on the top of the chamber 1, and an exhaust pipe assembly 4 connected to the chamber 1.

[0050] Furthermore, the asphalt loading workshop also includes a flue gas treatment system 5, an exhaust duct 6, a first exhaust fan 7, and a second exhaust fan 8. The flue gas treatment system 5 (only the activated carbon adsorption box portion of the flue gas treatment system 5 is shown in the attached diagram) is connected to the exhaust duct assembly 4. The flue gas treatment system 5 is based on existing technology (such as the asphalt flue gas treatment system 5 disclosed in Chinese patent document CN218763437U), used to treat asphalt fumes to ensure they meet environmental protection requirements before being released into the atmosphere. The air inlet of the exhaust duct 6 is connected to the flue gas treatment system 5, and the exhaust duct 6 has two air outlets; the first exhaust fan 7 and the second exhaust fan 8 are respectively connected to the two air outlets of the exhaust duct 6.

[0051] During asphalt loading operations, either the first induced draft fan 7 or the second induced draft fan 8 is activated to provide power for drawing asphalt fumes into the fume treatment system 5, thus ensuring that harmful asphalt fumes do not drift outside the chamber 1. Since the first induced draft fan 7 and the second induced draft fan 8 are not activated simultaneously, but rather one fan is always on standby, even if one fan malfunctions, the other can be activated promptly. This ensures that the asphalt fumes inside the chamber 1 are timely drawn into the asphalt fume treatment system 5, and that personnel operating the asphalt tanker inside the chamber 1 will not pose a threat to their health.

[0052] In this invention, multiple material dispensing components 3 can be provided, thereby enabling simultaneous filling of asphalt into multiple asphalt tank trucks. For example... Figure 5 As shown, optionally, the feeding assembly 3 includes a bracket 301, a fixed feeding tube 302, a lifting feeding tube 303, a transmission screw 304, an annular connector 305, a connecting wing plate 306, and a drive mechanism 307.

[0053] The support 301 is a steel frame structure, which is fixedly installed on the top of the chamber 1. The fixed discharge pipe 302 is fixedly installed on the support 301 and connected to the asphalt finished product tank. Thus, under the action of the asphalt pump, the finished asphalt in the asphalt finished product tank can be transported to the fixed discharge pipe 302. The lifting discharge pipe 303 is movably sleeved on the fixed discharge pipe 302, so that the lower end of the lifting discharge pipe 303 can extend into the interior of the chamber 1. When loading asphalt, the lower end of the lifting discharge pipe 303 extends into the asphalt storage tank of the asphalt tanker truck. This can avoid asphalt splashing during the asphalt loading operation, and at the same time, asphalt fumes are not easily dispersed to the top side of the chamber 1.

[0054] The transmission screw 304 is rotatably mounted on the bracket 301; and the drive mechanism 307 is mounted on the bracket 301, and the output shaft of the drive mechanism 307 is connected to the transmission screw 304 for driving the transmission screw 304 to rotate.

[0055] The annular connector 305 is fixedly mounted on the upper end of the lifting and discharging pipe 303, and is sleeved on the fixed discharging pipe 302. The connecting wing plate 306 is connected to the outer wall of the annular connector 305, and is movably sleeved on the transmission screw 304. When the drive mechanism 307 drives the transmission screw 304 to rotate, the connecting wing plate 306 can move up and down relative to the transmission screw 304, thereby driving the annular connector 305 and the lifting and discharging pipe 303, enabling the lifting and discharging pipe 303 to rise and fall.

[0056] It is understandable that, in order to enable the connecting wing plate 306 to move up and down relative to the transmission screw 304, the connecting wing plate 306 can be threaded into the transmission screw 304, or the ball screw nut can be used to maintain the movable connection with the transmission screw 304.

[0057] like Figures 3 to 5 As shown, optionally, the top of the chamber 1 is provided with a discharge port 101 for the lower end of the lifting discharge pipe 303 to extend into the chamber 1; there are two transmission screws 304, and the two transmission screws 304 are respectively located on both sides of the lifting discharge pipe 303; there are two connecting wing plates 306, and the two connecting wing plates 306 are respectively movably sleeved on the two transmission screws 304.

[0058] By installing drive screws 304 on both sides of the lifting and discharging pipe 303, and having two connecting wing plates 306 movably mounted on the two drive screws 304 respectively, more balanced support can be provided for the lifting and discharging pipe 303. When the drive mechanism 307 drives the drive screws 304 to rotate, the force on both sides of the lifting and discharging pipe 303 is even, thus preventing tilting or jamming, allowing the lifting and discharging pipe 303 to move stably up and down, ensuring smooth operation of the asphalt tanker truck. Furthermore, during long-term use of the discharging assembly 3, the two drive screws 304 can better bear the weight of the lifting and discharging pipe 303 itself, improving the safety of loading operations.

[0059] like Figure 5 As shown, optionally, the drive mechanism 307 is a dual-shaft geared motor; a worm gear is fixedly sleeved on the upper part of the transmission screw 304; the output shaft of the dual-shaft geared motor is connected to a worm; the worm and the worm gear cooperate. By using a dual-shaft geared motor in conjunction with a worm gear transmission structure, the transmission screw 304 can be driven to rotate simultaneously without the need for two motors, thus reducing equipment maintenance costs and asphalt loading operation costs.

[0060] like Figures 1 to 3 As shown, optionally, the exhaust duct assembly 4 includes a first exhaust duct 41; the first exhaust duct 41 extends into the chamber 1 from the rear side of the chamber 1, and is connected to the flue gas treatment system 5. Preferably, the first exhaust duct 41 can be provided with multiple air intakes inside the chamber 1. During the asphalt loading process, multiple air intakes can function simultaneously to quickly draw the flue gas into the first exhaust duct 41 and then transport it to the flue gas treatment system 5, thereby reducing the residence time of asphalt fumes in the chamber 1.

[0061] To prevent asphalt fumes from accumulating at the filling port of the asphalt storage tank, the exhaust pipe assembly 4 may optionally include a second exhaust pipe 42 connected to the first exhaust pipe 41. The intake port of the second exhaust pipe 42 is located inside the chamber 1 and faces the lifting discharge pipe 303. During the process of asphalt flowing from the lifting discharge pipe 303 into the asphalt storage tank, the generated asphalt fumes can be captured by the intake port of the second exhaust pipe 42, preventing the asphalt fumes from accumulating at the filling port of the asphalt storage tank. This effectively reduces the asphalt fumes content inside the chamber 1, protecting the health of the operators.

[0062] In addition, the fact that asphalt fumes do not accumulate at the filling port of the asphalt storage tank when operators close the filling port also protects the health of the operators.

[0063] like Figure 1 and Figure 3 As shown, optionally, the exhaust duct 6 includes an exhaust main duct 61 and two exhaust branch ducts 62 connected to the exhaust main duct 61; the first exhaust fan 7 and the second exhaust fan 8 are respectively connected to the two exhaust branch ducts 62; each exhaust branch duct 62 is rotatably equipped with a baffle plate 9. The shape of the baffle plate 9 can be based on the shape of the exhaust branch duct 62, and it can be a circular baffle plate 9 or a rectangular baffle plate 9. When the first exhaust fan 7 or the second exhaust fan 8 is not turned on, the baffle plate 9 in the exhaust branch duct 62 connected to the unturned exhaust fan is perpendicular to the axis of the exhaust branch duct 62, thereby ensuring that the treated asphalt fumes can only be directed to the normally turned-on exhaust fan.

[0064] like Figure 3 and Figure 6 As shown, optionally, a handwheel 2 is rotatably provided on the outer side of the air duct branch pipe 62. The handwheel 2 is connected to the rotating shaft 91 of the wind baffle 9, which makes it convenient for the operator to rotate the wind baffle 9 and adjust the included angle between the wind baffle 9 and the axial direction of the air duct branch pipe 62.

[0065] like Figure 1 and Figure 2As shown, optionally, a weighbridge 10 is installed inside the chamber 1, and the weighbridge 10 is located below the material discharge assembly 3. During asphalt loading operations, the asphalt tanker truck is positioned on the weighbridge 10, which can accurately control the amount of asphalt loaded and prevent overloading or underloading.

[0066] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
