Abstract
Disclosed is an air heater for a bulldozer, the complete air heater is in a horizontal type barrel shape, and an air exhaust pipe is led from the right side wall. The complete air heater comprises a combustion head, a combustion chamber and a heat exchanger, the combustion head comprises a motor, an oil pump, a combustion-supporting wind wheel and a big fan, the big fan and the oil pump are connected with each other to be fixed on one side of the motor through bolts, the combustion-supporting wind wheel is installed on the other side of the motor, the combustion chamber comprises a central connecting body, a flow guide disk, an ignition plug and a fuel volatilization net, the combustion chamber is connected with the rear surface of the combustion head, and the heat exchanger is covered on the outer portion of the combustion chamber. The air heater for the bulldozer is applicable to heating and defrosting a cab of the bulldozer, good in sealing effect, high in heat exchange efficiency, fast in heating speed, stable in effect, low in oil consumption and power consumption, capable of working by using a storage power for a long time and extremely low in exhaust emission, and the cab is free from abnormal odor.
Description
Technical field
The utility model relates to a kind of bulldozer air heater, is used for bulldozer cab heating, defrosting.
Background technique
Present domestic traditional bulldozer air heating apparatus need use engine water tank and using waste heat from tail gas, and this apparatus structure is simple, cheap, but there are problems such as heating speed is slow, heat exchange efficiency is low in this air heating apparatus.
Summary of the invention
The purpose of the utility model provides a kind of bulldozer air heater, solves that traditional bulldozer air heater heating speed is slow, heat exchange efficiency is low, discharge amount of exhaust gas is than problems such as height.
The purpose of the utility model realizes as follows: complete machine is a horizontal cylinder shape, and right side wall picks out outlet pipe; Complete machine comprises burning head, firing chamber and heat exchanger; Burning head comprises motor, oil pump, combustion-supporting wind wheel and big fan, and big fan and oil pump connect through bolt and arrive the motor side, and combustion-supporting wind wheel is installed in the motor another side; The firing chamber comprises center connecting body and diversion disk, igniter plug, fuel oil volatilization net, and the firing chamber is connected the burning head back; The outside, firing chamber is covered with heat exchanger.Igniter plug energising preheating reaches rated temperature rear electromagnetic valve and electrical power work during heater work, and fuel oil is sucked by oil pump and delivers to volatilization on the net; Fuel oil volatilizees immediately and mixes with the combustion-supporting air of being sent into by combustion-supporting wind wheel, and gas mixture burns in the firing chamber rapidly under the igniter plug high temperature action, and combustion gas are discharged by outlet pipe after the heat exchanger heat exchange simultaneously; Along with heat exchanger temperature rises, the flame detector action, control circuit cuts off the glow plug power supply; The heater normal combustion; Big fan sucks cool air in the compartment by cool air inlet under driven by motor, after the heat exchanger heating, send the compartment back to by hot air outlet, reaches heating purposes.
The utility model good sealing effect, heat exchange efficiency is high, the compartment free from extraneous odour, heating speed is fast, and effect stability consumes oily little power consumption, can use storage battery work for a long time, and toxic emission is extremely low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
