Description

Technical Field

[0001] This utility model belongs to the technical field of road construction equipment, specifically relating to an integrated device for storing, transporting and cleaning emulsified asphalt. Background Technology

[0002] In recent years, with the rapid increase in the mileage of high-grade highways, small-area and sudden pothole damage has become increasingly frequent. The traditional approach is to centrally produce hot-mix asphalt at the mixing plant and then transport it to the site by dump trucks. During winter or long-distance transport, the mixture cools rapidly, often falling below the lower limit of the paving temperature, necessitating on-site reheating or scrapping, resulting in material waste, low construction efficiency, and significant traffic disruption. To address this, the industry has begun using integrated maintenance vehicles with built-in insulated silos to achieve "patching on the go." However, after excavating a pothole, a layer of emulsified asphalt tack coat needs to be sprayed onto the bottom and sidewalls to ensure adhesion between the old and new surfaces. Currently, maintenance vehicles typically use gear pumps or plunger pumps to pump emulsified asphalt from the vehicle's storage tank to a handheld nozzle. This design has three main drawbacks: First, the emulsified asphalt has a solid content exceeding 60%, making it prone to forming an asphalt film on the pump body, valves, and the inner wall of the 20-30 meter long hose during downtime. This results in a sudden drop in flow rate and even pipe blockage upon restarting. Second, there is a lack of dedicated cleaning facilities on-site, requiring manual pipe disassembly and gasoline washing, which is time-consuming, polluting, and incomplete. Residue is sprayed out during subsequent applications, affecting interlayer adhesion. Third, the cleaning wastewater contains oil and surfactants, posing a high environmental risk if directly discharged. Therefore, there is an urgent need for a dedicated emulsified asphalt device that integrates stable delivery and rapid cleaning to meet the technical requirements of "rapid construction and rapid removal" in highway maintenance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an integrated device for the storage, transportation and cleaning of emulsified asphalt with high integration, fast cleaning and stable transportation.

[0004] The technical solution adopted to solve the above technical problems is: an integrated device for storing, transporting and cleaning emulsified asphalt. The asphalt outlet of the emulsified asphalt pressure tank is connected to the asphalt outlet pipe through a connecting pipe. An asphalt outlet valve is installed on the connecting pipe. The connecting pipe is located in the middle of the asphalt outlet pipe and is perpendicular to the asphalt outlet pipe. A diesel filling structure, a clean water filling structure and an air blowing structure are sequentially installed on the asphalt outlet pipe upstream of the connecting pipe. An asphalt spraying valve and an asphalt spraying port are installed on the asphalt outlet pipe downstream of the connecting pipe.

[0005] As a preferred technical solution, the emulsified asphalt pressure tank is provided with an asphalt filling port, an air inlet pipe, an exhaust pipe, a pressure gauge, and a tank safety valve at the top of the tank body, a pressure sensor at the bottom, a sealing cap on the asphalt filling port, an air inlet valve on the air inlet pipe, and an exhaust valve on the exhaust pipe.

[0006] As a preferred technical solution, the clean water filling structure is provided with a clean water filling valve on the clean water filling pipe.

[0007] As a preferred technical solution, the diesel refueling structure is provided with a diesel refueling valve on the diesel refueling pipe.

[0008] As a preferred technical solution, the air blowing structure includes an air blowing inlet pipe, an air blowing control valve, and an air blowing check valve. The air blowing inlet pipe is connected to the asphalt output pipe in sequence through the air blowing control valve and the air blowing check valve.

[0009] The beneficial effects of this utility model are as follows: This invention achieves zero-blockage pipe restart during intermittent operation by combining a diesel filling structure and an air blowing structure, solving the common problems of intermittent pipe blockage and manual pipe dismantling in the industry, and improving construction efficiency.

[0010] After construction, this invention first introduces a high-pressure airflow into the asphalt output pipe via an air blowing structure to clear most of the emulsified asphalt from the pipe. Then, a diesel fuel injection structure injects diesel fuel into the pipe to wash the pipe wall, reducing the adhesion resistance of the emulsified asphalt. This is then combined with the high-pressure airflow from the air blowing structure to further clear the emulsified asphalt from the output pipe. Finally, a water injection structure injects clean water into the asphalt output pipe for thorough cleaning. This invention offers the advantages of stable delivery and rapid cleaning.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments.

[0014] exist Figure 1In this embodiment, the integrated device for storing, transporting, and cleaning emulsified asphalt has an asphalt outlet of the emulsified asphalt pressure tank connected to an asphalt outlet pipe 12 via a connecting pipe. An asphalt outlet valve 9 is installed on the connecting pipe. The connecting pipe is located in the middle of the asphalt outlet pipe 12 and is perpendicular to the asphalt outlet pipe 12. A diesel fuel filling structure, a water filling structure, and an air blowing structure are sequentially arranged on the asphalt outlet pipe 12 upstream of the connecting pipe for injecting diesel fuel, water, and high-pressure gas into the asphalt outlet pipe 12, respectively. An asphalt spraying valve 11 and an asphalt spraying port 10 are installed on the asphalt outlet pipe 12 downstream of the connecting pipe.

[0015] In this embodiment, the emulsified asphalt pressure tank has an asphalt filling port, an air inlet pipe 6, an exhaust pipe 20, a pressure gauge 4, and a tank safety valve 2 installed on the top of the tank body 7, and a pressure sensor 8 installed at the bottom. A sealing cap 3 is installed on the asphalt filling port, an air inlet valve 5 is installed on the air inlet pipe 6, and an exhaust valve 1 is installed on the exhaust pipe 20. The air inlet pipe 6 is used to inject pressurized gas into the tank body 7, the pressure gauge 4 is used to monitor the pressure inside the tank body 7, and the tank safety valve 2 automatically controls the pressure of the tank body 7. When the pressure of the tank body 7 exceeds a set safety value, the tank safety valve 2 automatically starts to release pressure. The exhaust valve 1 is used to manually control the pressure of the emulsified asphalt tank, and the pressure sensor 8 is used to weigh and measure the emulsified asphalt inside the tank in real time.

[0016] In this embodiment, the water filling structure is a water filling pipe 19 with a water filling valve 18 installed on it, the diesel filling structure is a diesel filling pipe 14 with a diesel filling valve 13 installed on it, and the air blowing structure includes an air blowing inlet pipe 17, an air blowing control valve 16, and an air blowing check valve 15. The air blowing inlet pipe 17 is connected to the asphalt output pipe 12 in sequence through the air blowing control valve 16 and the air blowing check valve 15.

[0017] The working principle of this utility model is as follows: When asphalt needs to be sprayed, open the asphalt output valve 9 and the asphalt spraying valve 11. The gas pressure in the emulsified asphalt pressure tank drives the emulsified asphalt to be transported and sprayed. After the emulsified asphalt is sprayed, first close the asphalt output valve 9, open the air blowing control valve 16, and introduce high-pressure airflow into the asphalt output pipe 12 through the air blowing inlet pipe 17 to clear most of the emulsified asphalt in the asphalt output pipe 12. Close the air blowing control valve 16, open the diesel fuel filling valve 13 to add diesel fuel to the asphalt output pipe 12 to wash the pipe wall and reduce the adhesion resistance of the emulsified asphalt. Open the air blowing control valve 16 again to clear the emulsified asphalt in the output pipe through the high-pressure airflow. Finally, close the air blowing control valve 16, open the clean water filling valve 18 to add clean water to the asphalt output pipe 12 for final cleaning until the asphalt output pipe 12 is completely clean.
