Description

Technical Field

[0001] This utility model relates to the field of asphalt heating technology, specifically to an efficient asphalt heating device for highway maintenance equipment. Background Technology

[0002] Currently, in the process of highway maintenance, because many highways are long, the repair work of a section of highway often takes several days. As a result, the asphalt left over after the equipment is used during the highway repair process needs to be stored. Transporting the remaining asphalt back and forth is not only troublesome, but also increases transportation costs.

[0003] Currently, the remaining asphalt is stored outdoors, usually in a mixing and heating drum. However, being outdoors can easily cause the asphalt to lose temperature and solidify. It needs to be reheated and melted the next day, which delays construction time and reduces efficiency. However, continuously heating the asphalt leads to high energy consumption, and the current drums are not easy to insulate, resulting in rapid temperature loss of the asphalt. Utility Model Content

[0004] The purpose of this invention is to address the problems of asphalt easily solidifying outdoors, thus reducing construction efficiency, and the current material cylinders being inconvenient for heat preservation, resulting in rapid asphalt temperature loss. This invention provides an efficient asphalt heating device for highway maintenance equipment.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A high-efficiency asphalt heating device for highway maintenance equipment includes a material cylinder, a cylinder cover at the upper end of the material cylinder, and multiple support legs fixedly installed on the lower side of the material cylinder. An annular heat storage box is fixedly sleeved on the side wall of the material cylinder and is in contact with the material cylinder. A heating mechanism is provided on the lower side of the annular heat storage box, and a heat preservation mechanism is provided on the side wall of the material cylinder above the annular heat storage box. A discharge pipe is provided on the bottom side wall of the material cylinder, and a control valve is provided on the side wall of the discharge pipe.

[0007] Preferably, the heating mechanism includes an annular protective shell, which is fixedly installed on the lower side wall of the annular heat storage box, and an annular electric heating plate is provided inside the annular heat storage box.

[0008] Preferably, the lower end of the annular protective shell is open, and a movable sealing plate is provided at the open end of the annular protective shell. The movable sealing plate has wire holes on its side wall, and multiple positioning screw holes are provided on the peripheral side wall of the movable sealing plate. A positioning screw groove is provided on the end face of the open end of the annular protective shell, and the positioning screw groove is matched with the positioning screw hole. A positioning bolt is provided between the annular protective shell and the movable sealing plate.

[0009] Preferably, the heat preservation mechanism includes a connecting ring plate, which is slidably sleeved on the outer side wall of the material cylinder, and a heat preservation cover is fixedly installed on the lower side wall of the connecting ring plate, and the heat preservation cover is slidably sleeved on the outer side wall of the annular protective shell.

[0010] Preferably, a plurality of solar panels are provided on the outer wall of the heat insulation cover, and the plurality of solar panels are arranged in a ring-like manner.

[0011] Preferably, guide rails are symmetrically installed on the side wall of the material cylinder, and guide sliders are slidably installed inside the guide rails, with one side of the guide sliders fixedly installed on the connecting ring plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, the annular heat storage box, annular protective shell, and annular heating plate are designed to keep the asphalt in the barrel warm by means of the annular heat storage box and the internal heat transfer oil. The heat insulation cover effectively reduces heat loss from the asphalt, thus maintaining the temperature of the asphalt in the barrel and reducing its curing degree. The solar panel stores electrical energy under sunlight, which powers the annular heating plate, further increasing the temperature of the heat transfer oil in the annular heat storage box. This maintains the asphalt in the barrel at a higher temperature, further reducing the probability of curing and facilitating faster asphalt melting the next day. This reduces waiting time and effectively improves on-site construction efficiency. Attached Figure Description

[0022] like Figure 1-3 As shown, a high-efficiency asphalt heating device for highway maintenance equipment includes a material cylinder 1. A cylinder cover 11 is provided at the upper end of the material cylinder 1, and multiple support legs 2 are fixedly installed on the lower side of the material cylinder 1. The material cylinder 1 is used to store surplus asphalt that has not been used in a timely manner by the highway maintenance equipment. An annular heat storage box 9 is fixedly fitted onto the side wall of the material cylinder 1, and the annular heat storage box 9 is in contact with the material cylinder 1. The annular heat storage box 9 is filled with heat-conducting oil, which effectively reduces heat loss from the material cylinder 1, thereby improving the heat preservation effect on the asphalt.

[0023] A heating mechanism is provided on the lower side of the annular heat storage box 9. The heating mechanism includes an annular protective shell 7, which is fixedly installed on the lower side wall of the annular heat storage box 9. An annular electric heating plate 15 is provided inside the annular heat storage box 9. The annular electric heating plate 15 is in contact with the annular heat storage box 9. The annular electric heating plate 15 can heat the heat-conducting oil in the annular heat storage box 9, and the annular protective shell 7 can effectively reduce the heat loss of the annular electric heating plate 15.

[0024] The lower end of the annular protective housing 7 is open, and a movable sealing plate 8 is provided at the open end of the annular protective housing 7. The movable sealing plate 8 has wire holes 12 on its side wall, and multiple positioning screw holes 10 are provided on the peripheral side wall of the movable sealing plate 8. A positioning screw groove is provided on the end face of the open end of the annular protective housing 7, and the positioning screw groove is matched with the positioning screw hole 10. A positioning bolt is provided between the annular protective housing 7 and the movable sealing plate 8. By setting it to be detachable, the installation and disassembly of the annular protective housing 7 can be effectively facilitated.

[0025] A heat preservation mechanism is provided on the side wall of the material cylinder 1 above the annular heat storage box 9. The heat preservation mechanism includes a connecting ring plate 5, which is slidably sleeved on the outer side wall of the material cylinder 1. Guide slide rails 3 are symmetrically installed on the side wall of the material cylinder 1, and guide sliders 4 are slidably installed inside the guide slide rails 3. One side of the guide slider 4 is fixedly installed on the connecting ring plate 5. The connecting ring plate 5 can be easily moved by the guide slide rails 3 and the guide sliders 4.

[0026] An insulation cover is fixedly installed on the lower side wall of the connecting ring plate 5, and the insulation cover is slidably fitted onto the outer side wall of the annular protective shell 7. The insulation cover effectively insulates the annular heat storage box 9, further reducing heat loss. Multiple solar panels 6 are installed on the outer side wall of the insulation cover, arranged in a ring. The solar panels 6 can store electrical energy under sunlight, thereby providing energy for continuous outdoor heating of the heat transfer oil, thus achieving energy conservation. A discharge pipe 13 is installed on the bottom side wall of the material cylinder 1, and a control valve 14 is installed on the side wall of the discharge pipe 13. The discharge pipe 13 and the control valve 14 facilitate the use of asphalt.

[0027] In summary: Residual and unused asphalt for highway repair is placed in the material cylinder 1. Under high-temperature and sunlight conditions, the protective cover, connecting ring plate 5, and multiple solar panels 6 can be pushed upwards. The connecting ring plate 5 moves along the guide rail 3 via the guide slider 4. This allows the sunlight to heat the heat-conducting oil in the annular heat storage box 9, and also enables the solar panels 6 to store electrical energy. When the ambient temperature is low, the insulation cover is lowered to protect the annular heat storage box 9, reducing heat loss. The electrical energy from the solar panels 6 then supplies the annular electric heating plate 15, activating it to further heat the heat-conducting oil in the annular heat storage box 9. This effectively transfers heat to the asphalt in the material cylinder 1, facilitating asphalt melting. When needed, the control valve 14 is opened, and the asphalt is discharged through the discharge pipe 13.

[0028] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
