Description

Technical Field

[0001] This utility model relates to the field of asphalt product technology, specifically a modified asphalt freeze-demolding device. Background Technology

[0002] Asphalt paving bricks are made by uniformly mixing liquid asphalt with an appropriate amount of aggregates (such as crushed stone and sand) to form an asphalt mixture. This mixture is then poured into molds of a specific shape and shaped using processes such as vibration and compaction. Modified asphalt can better bond with aggregates, making the paving brick structure more stable. For example, adding modifiers such as anti-stripping agents can enhance the adhesion between the asphalt and the aggregate surface, effectively preventing aggregates from detaching from the paving bricks and improving the overall quality and service life of the paving bricks. They are mainly used for paving roads, squares, parking lots, and other similar locations. Because asphalt paving bricks have good wear resistance, anti-slip properties, and impermeability, they can withstand the loads of vehicles and pedestrians while also effectively draining water, making them widely used in urban road construction and landscaping projects.

[0003] Because asphalt is highly fluid at high temperatures, it needs to be cooled and solidified before it can be demolded. The traditional cooling method is natural cooling. The advantage of natural cooling is that the processing cost is lower, but it requires a large storage area. At the same time, the natural cooling speed is slow and cannot quickly demold to improve the utilization rate of the mold. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a modified asphalt freeze-drying device, which solves the problems mentioned in the background art.

[0021] See Figures 1-4 A modified asphalt freezing and demolding device includes a conveyor belt 1 and a mold 2. The mold 2 is placed above the conveyor belt 1 and moves with the conveyor belt 1. The outer ring of the conveyor belt 1 is provided with a spray ring 3 for spraying cooling gas. The spray ring 3 is connected to a refrigeration unit. By cooling the air and making the cold air flow, the mold 2 is frozen. The outer ring of the spray ring 3 of the conveyor belt 1 is wrapped with a heat insulation cover 4. The heat insulation cover 4 is provided with a fan mechanism 5 located away from the spray ring 3. The fan mechanism 5 discharges the gas to form a circulation of the cold air in the heat insulation cover 4. The mold 2 is placed on the conveyor belt 1, and the conveyor belt 1 moves the mold 2 closer to the spray ring 3. The cold air sprayed by the spray ring 3 cools the asphalt in the mold 2, thereby enabling the asphalt to solidify and facilitate demolding.

[0022] The mold 2 includes a fixed frame 201, an upper pressure plate 202 is slidably connected inside the fixed frame 201, a pressure handle 203 is fixedly installed above the upper pressure plate 202, the pressure handle 203 extends to the outside of the fixed frame 201, a base plate 204 is inserted below the fixed frame 201, the insertion direction of the base plate 204 is perpendicular to the moving direction of the conveyor belt 1, the base plate 204 is pulled out, and the pressure handle 203 is pressed down, so that the upper pressure plate 202 can be moved, thereby demolding the asphalt inside the fixed frame 201.

[0023] The conveyor belt 1 is partially located inside the insulation cover 4 and partially located outside the insulation cover 4. A blower unit 6 is provided at the inlet and outlet of the insulation cover 4. The airflow of the blower unit 6 is directed towards the center of the insulation cover 4. By providing the blower unit 6, air can be blown into the center of the insulation cover 4. The blower unit 6 includes a nozzle with openings. The nozzle is built inside the insulation cover 4 and the inlet extends to the outside of the insulation cover 4. A blower is provided at the inlet to reduce the leakage of cold air.

[0024] The blower unit 6 at the outlet is connected to the spray ring 3 for cold air. The blower inlet of the blower unit 6 on this side is connected to the cold air pipe. The blower unit 6 at the inlet draws gas from the insulation cover 4 for blowing. The blower inlet at this location is connected to the outlet of the induced draft mechanism 5, so that some of the cold air is returned and the rest of the cold air can be recovered to the refrigeration unit.

[0025] There are multiple spray rings 3, which are equidistantly arranged on the outer ring of the conveyor belt 1. One spray ring 3 is located at the inlet of the heat insulation cover 4, and the spray ring 3 at the inlet can cool the mold 2 that enters in time. Another spray ring 3 is located at the outlet of the heat insulation cover 4, and the spray ring 3 at the outlet can move the cold air away from the blower unit 6 under the action of the blower unit 6.

[0026] A demolding platform 7 is provided in front of the conveyor belt 1. A baffle 8 is fixedly installed on the side of the demolding platform 7 away from the conveyor belt 1. A through groove 9 is provided above the demolding platform 7. A chute 10 is provided below the demolding platform 7. When the mold 2 moves above the demolding platform 7 via the conveyor belt 1, the bottom plate 204 is pulled out on one side, and then the fixing frame 201 can fall above the demolding platform 7. By pressing the handle 203, the asphalt part can fall from the through groove 9 and then be discharged from the chute 10.

[0027] When in use, asphalt is placed inside the mold 2 and the mold 2 is placed above the conveyor belt 1. The conveyor belt 1 can transport the mold 2 to the inside of the heat insulation cover 4. The inside of the heat insulation cover 4 is equipped with a spray ring 3 for spraying cold air. The sprayed cold air freezes the mold 2 and the asphalt inside the mold 2, thereby solidifying the asphalt and making it easy to demold.

[0028] Inside the insulation cover 4, there are blower units 6 located at the outlet and inlet, and the blower units 6 are restricted from blowing air into the insulation cover 4. The airflow blows cold air into the insulation cover 4, and the air-guiding mechanism 5 returns the cold air to the refrigeration unit for circulation and refrigeration. This arrangement can reduce the loss of cold air.
