Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figures, the utility model provides an asphalt cooling and heat exchanging device, which comprises a heat exchanging pipe 1 and a storage tank 2 connected with the end of the heat exchanging pipe 1, wherein the heat exchanging pipe 1 comprises at least two asphalt pipelines 3 with spiral structures, and one end of each asphalt pipeline 3 extends to the outside of the starting end of the heat exchanging pipe 1 and is provided with a flow adjusting device 4; the other end of the asphalt pipeline 3 passes through the tail end of the heat exchange pipe 1 and extends to the inside of the storage tank 2; the upper part of the heat exchange tube 1 is provided with a water inlet 5, and the lower part is provided with a water outlet 6.
Before the asphalt cooling and converting device is used, circulating water is injected into a space between the heat exchange tube 1 and the asphalt pipeline 3 by using the water inlet 5 arranged at the upper part of the heat exchange tube 1. Thereafter, the asphalt is injected into the asphalt pipe 3 by opening a flow rate adjusting device 4 provided at one end of the asphalt pipe 3 outside the heat exchange pipe 1. The flow velocity of the bitumen inside the helical pipe will be slower than in the straight pipe, so the circulating water is able to provide a more adequate cooling of the bitumen. The asphalt is then stored in the storage tank 2 after passing through the heat exchange pipe 1 through the other end of the asphalt pipe 3. Above-mentioned pitch cooling device is owing to adopt helical structure, has consequently reduced the velocity of flow of pitch in pitch pipeline 3 to make pitch carry out abundant heat transfer under the circulating water effect of heat exchange tube 1 inside, thereby improved pitch cooling heat transfer device's heat transfer effect.
Further, one end of the asphalt pipeline 3 is movably connected with a high temperature resistant pipe 7, and the high temperature resistant pipe 7 is provided with an interface connected with the flow regulating device 4. The flow regulating device 4 preferably employs a flow meter and a valve, and can be used to regulate the pressure inside the asphalt pipeline 3 before it is filled with asphalt. During use, the actual inflow rate may be obtained by a flow meter to regulate the flow rate of the asphalt pipeline 3 through a valve.
Further, a protective shell 8 is arranged at the joint of the high temperature resistant pipe 7 and the asphalt pipeline 3. It should be added here that, because of the possibility of damage to the high temperature resistant pipe 7 and/or the asphalt pipeline 3 during use, a movable connection is preferably used between the high temperature resistant pipe 7 and the asphalt pipeline 3, including but not limited to a flange connection, in order to replace one or both of the high temperature resistant pipe 7 and the asphalt pipeline 3. Correspondingly, the protective shell 8 is arranged at the joint to prevent the asphalt from leaking from the joint, so that the safety of the asphalt cooling and heat exchanging device is improved.
Further, the drain opening 6 is provided with a first valve 9. The bottom of the storage tank 2 is provided with a first valve 9 for discharging the circulating water. Along with pitch cooling heat transfer device carries out the in-process that cools down to pitch, because the circulating water carries out the heat exchange with pitch, consequently can lead to the temperature of circulating water to rise constantly to consequently, make the effect of heat transfer reduce gradually, consequently, need discharge the circulating water in order to gain new circulating water, thereby guarantee pitch cooling heat transfer device's heat transfer effect.
Further, the bottom of the storage tank 2 is provided with a discharge opening 10, and the discharge opening (10) is provided with a second valve 11. The second valve 11 is disposed at the bottom of the storage tank 2 to discharge the cooled asphalt.
