Description

Technical Field

[0001] This utility model relates to the field of combined vibratory rollers, and in particular to an oil-water mixing spraying system for combined vibratory rollers. Background Technology

[0002] Combination vibratory rollers typically have a steel front wheel and a rubber rear wheel. During asphalt pavement compaction, to ensure neither the steel nor the rubber wheel adheres to asphalt, and to meet the requirements of construction quality and work efficiency, a spraying system is required at the wheel locations. Current technology involves spraying water at the steel wheel location and spraying an asphalt release agent or vegetable oil at the rubber wheel location. This spraying method solves the problem of asphalt adhesion between the steel and rubber wheels, thereby ensuring the compaction quality of the asphalt pavement.

[0003] In practice, the non-stick asphalt effect of steel wheels meets construction requirements, but the non-stick asphalt effect of rubber wheels is not ideal, specifically as follows: The first method, spraying a release agent on the rubber wheel, is particularly problematic in summer. If the release agent is not used up in the spray tank after a few days, it will solidify into lumps and have an odor, making the nozzles prone to clogging during subsequent use. Furthermore, the inconvenience of purchasing release agents discourages construction workers from using them. The second method, spraying vegetable oil, is costly, and its high viscosity and susceptibility to oxidation in air, especially at low temperatures, easily clogs the nozzles, resulting in poor non-stick asphalt effect on the rubber wheels and failing to meet normal construction requirements. The third method, the oil, air, and water mixed spraying system currently used in tire rollers, while ensuring construction quality and operational efficiency, requires an additional air system, making the system complex. Since combined vibratory rollers lack an air source, this spraying method is unsuitable for them.

[0004] Therefore, it is necessary to develop new oil-water mixing spraying systems to overcome the shortcomings of existing technologies. Summary of the Invention

[0005] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, this utility model provides an oil-water mixed spraying system for combined vibratory rollers. After the oil and water are mixed and emulsified, the anti-sticking effect of the asphalt is good. The system has a simple structure, saves the cost of spraying oil during operation, and can ensure the construction quality and operation efficiency of combined vibratory rollers.

[0006] Technical Solution: This utility model discloses an oil-water mixing spraying system for a combined vibratory roller, characterized in that it includes a water tank and an oil tank, the water tank being connected to a steel wheel spray pipe, a diaphragm pump being installed between the water tank and the steel wheel spray pipe, and the water tank being connected to an oil-water mixing device; the oil-water mixing device is connected to the oil tank, and the oil-water mixing device is connected to a rubber wheel spray pipe, a second diaphragm pump being installed between the oil-water mixing device and the rubber wheel spray pipe; both the steel wheel spray pipe and the rubber wheel spray pipe are equipped with several nozzles at their ends.

[0007] The oil tank is installed at a position higher than the oil-water mixing device.

[0008] A filter is provided between the water tank and the diaphragm pump.

[0009] A flow regulating valve is provided between the diaphragm pump and the oil-water mixing device.

[0010] The oil tank and the oil-water mixing device are equipped with a second filter and a second flow regulating valve.

[0011] A filter is provided between the oil-water mixing device and the diaphragm pump.

[0012] Beneficial effects: Compared with the prior art, this utility model has the following significant advantages: This utility model solves the problem of asphalt sticking to the rubber tires during operation of combined vibratory rollers, which affects construction quality and work efficiency, by designing an oil-water mixed spraying system. The system is simple in structure and can save on the cost of sprayed oil during operation. Attached Figure Description

Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] This utility model discloses an oil-water mixing spraying system for a combined vibratory roller, comprising a water tank 3 and an oil tank 6. The water tank 3 is connected to a steel wheel sprinkler pipe 1, and a diaphragm pump 5 is installed between the water tank 3 and the steel wheel sprinkler pipe 1. The water tank 3 is also connected to an oil-water mixing device 10. The oil-water mixing device 10 is connected to the oil tank 6 and a rubber-tired sprinkler pipe 14, and a second diaphragm pump 12 is installed between the oil-water mixing device 10 and the rubber-tired sprinkler pipe 14. Both the steel wheel sprinkler pipe 1 and the rubber-tired sprinkler pipe 14 have several nozzles 2 at their ends. The oil tank 6 is installed higher than the oil-water mixing device 10. A filter 4 is installed between the water tank 3 and the first diaphragm pump 5. A flow regulating valve 8 is installed between the first diaphragm pump 5 and the oil-water mixing device 10.

A third filter 11 is installed between the oil-water mixing device 10 and the second diaphragm pump 12.

[0017] During operation, water is drawn from water tank 3 by diaphragm pump 5. Part of the water goes directly to the steel wheel sprinkler pipe 1 and is sprayed through nozzle 2, while the rest goes to the oil-water mixing device 10. Oil is drawn from oil tank 6 by gravity into the oil-water mixing device 10. The oil and water are thoroughly mixed to form an oil-water emulsion, which is then drawn by diaphragm pump 12 and sprayed onto the surface of the rubber wheel through nozzle 2 on the rubber wheel spray pipe 14. Oil tank 6 is installed higher than the oil-water mixing device 10, and the oil in oil tank 6 can be forced into the oil-water mixing device 10 through pressure differential.

[0018] The present invention is equipped with a filter 4 between the water tank 3 and the diaphragm pump 5 to filter impurities in the water; a flow control valve 8 is configured between the diaphragm pump 5 and the oil-water mixing device 10 to regulate the amount of water entering the oil-water mixing device 10; a filter 7 and a flow control valve 9 are arranged between the oil tank 6 and the oil-water mixing device 10 to filter impurities in the oil and control the amount of oil entering the oil-water mixing device 10, respectively; a filter 3 11 is provided between the oil-water mixing device 10 and the diaphragm pump 12 to filter out the gel-like substances formed by the long-term residue of the oil-water emulsion in the oil-water mixing device 10, and to protect the diaphragm pump 12.

[0019] This invention features a simple system design that saves on spraying oil costs during operation. It also solves the problem of asphalt residue on the rubber tires of combined vibratory rollers, which negatively impacts construction quality and work efficiency.
