Consider the power take off who adopts fuel engine as the construction of colored road surface usually when the construction to fuel engine exhaust high temperature flue gas, the utility model aims to provide an utilize fuel engine's flue gas heat to clear up the road surface and carry out the device that heats to the road surface, specifically realize by following technical scheme:
a pavement cleaning device before construction of a colored pavement comprises a frame, a fuel engine, a fan, an air pipe, a heat exchange cylinder and a flue gas pipe, wherein the fuel engine, the fan and the heat exchange cylinder are all arranged on the frame; a smoke exhaust pipe of the fuel engine is connected with the smoke pipe, the middle part of the smoke pipe is arranged in the heat exchange cylinder, and high-temperature smoke exhausted by the fuel engine enters the heat exchange cylinder and transfers heat to air in the air pipe; the air outlet of the air pipe and the smoke outlet of the smoke pipe are both positioned at the lower part of the frame and opposite to the ground, and the smoke outlet of the smoke pipe is positioned in front of the air outlet.
The pavement cleaning device before construction of the colored pavement is further designed in that a cleaning brush positioned at the rear side of an air outlet of the air pipe is arranged at the lower part of the frame.
The pavement cleaning device before construction of the colored pavement is further designed in that the cleaning brush is elastically arranged at the lower part of the frame.
The pavement cleaning device before construction of the colored pavement is further designed in that heat exchange fins are arranged on the part, located in the heat exchange cylinder, of the flue gas pipe.
The pavement cleaning device before construction of the colored pavement is further designed in that the heat exchange fins are provided with ventilation holes.
The pavement cleaning device before construction of the colorful pavement is further designed in that a heat insulation layer is arranged on the outer side of the bottom wall of the heat exchange cylinder and is arranged on the frame through the heat insulation layer.
The pavement cleaning device before construction of the colored pavement is further designed in a way that a filter is connected in series in the flue gas pipe.
The utility model has the advantages that:
the utility model discloses utilize fuel engine's flue gas waste heat to heat the air, the flue gas through the heat transfer cooling at first carries out the primary heating to ground, and then the air that the heat transfer heaied up carries out the secondary heating and sweeps the road surface, treats the road surface of construction and carries out better heating and cleaning work.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The invention is further described with reference to the drawings and examples in the following description:
the pavement cleaning device before construction of the colorful pavement comprises a frame 1, a fuel engine (not shown in the figure), a fan 2, an air pipe 3, a heat exchange cylinder 4 and a flue gas pipe 5, wherein the fuel engine, the fan 2 and the heat exchange cylinder 4 are all arranged on the frame, the air pipe 3 is connected with an air outlet of the fan 2, and the heat exchange cylinder 4 is connected in series in the air pipe; a smoke exhaust pipe of the fuel engine is connected with the smoke pipe 5, the middle part of the smoke pipe is arranged in the heat exchange cylinder, and high-temperature smoke exhausted by the fuel engine enters the heat exchange cylinder and transfers heat to air in the air pipe; the air outlet of the air pipe and the smoke outlet of the smoke pipe are both positioned at the lower part of the frame and opposite to the ground, and the smoke outlet of the smoke pipe is positioned in front of the air outlet.
When the device is applied, a paint bucket, a spraying device and other equipment are also loaded on a frame, a diesel engine is generally adopted by a fuel engine and used as a power device for frame walking and spraying operation, the temperature of flue gas exhausted by the fuel engine is usually about 400 ℃, a fan 2 (driven by a generator driven by the fuel engine) sends air into a heat exchange cylinder, and high-temperature flue gas passes through a flue gas pipe 5 in the heat exchange cylinder to exchange heat with the air, so that the air is heated, and certain waste heat still exists when the flue gas is cooled; the cooled flue gas is sprayed to the ground to be operated for primary heating, then the air subjected to heat exchange and temperature rise is used for carrying out secondary heating and blowing on the road surface, and the road surface to be constructed is subjected to better heating and cleaning work.
Because the fuel engine contains trace carbon black generated by insufficient combustion, the lower part of the frame is provided with the cleaning brush 6 positioned at the rear side of the air outlet of the air pipe while air purging is carried out, and the cleaning brush is arranged at the lower part of the frame by utilizing the elasticity of a longitudinally arranged spring, so that the cleaning brush is pressed with trace elasticity and is applied to the road surface, and a better cleaning effect is achieved. And cleaning the road surface to be constructed by using the cleaning brush for one time.
In particular, in order to ensure that the flue gas pipe in the heat exchange cylinder has better heat exchange with the air in the heat exchange cylinder, the part of the flue gas pipe in the heat exchange cylinder is provided with heat exchange fins 51. The heat exchange fins are provided with ventilation holes.
The outer side of the bottom wall of the heat exchange cylinder is provided with a heat insulation layer 41 and is arranged on the frame through the heat insulation layer, so that heat transferred from the heat exchange cylinder to the frame is reduced. In order to reduce the particulate matter emission in the flue gas, a filter 7 is connected in series in the flue gas pipe.
