Embodiment
With specific embodiment, the utility model is illustrated by reference to the accompanying drawings:
As shown in Figure 1, and composition graphs 2, diesel engine combined type air filter is used in the extremely cold area of one, and described air-strainer 4 is arranged on the air intlet end of air inlet pipe of diesel engine 5; The electric heater 2 in order to carry out heating air inlet to air-strainer net is provided with inside the air-strainer net 1 of described air-strainer 4 entry end; Air-strainer net 1 is for the coarse filtration grains of sand, ice and snow; Described electric heater 2 connects power supply 8 by the resistance 11 of series connection with it, and is parallel with the control switch 12 of control box at the two ends of resistance 11; Described air inlet pipe of diesel engine 5 is provided with the vacuum pressure transmitter 7 in order to measure the degree of vacuum of air inlet pipe of diesel engine; Air inlet pipe of diesel engine 5 is stamped on the hole of φ 15, hole and is welded inipple 6, is tightened onto by vacuum pressure transmitter 7 on inipple 6; Described vacuum pressure change send 7 to be electrically connected with described control box 10; Described control box 10 receives the current signal of vacuum pressure transmitter feedback and exports opening or closing of control signal control control switch after carrying out analysing and processing, described electric heater 2 is connected with power supply 8 by resistance 11, electric heater is in the low temperature shelves work in order to improve intake temperature, guarantee diesel engine quick starting, or, described electric heater 2 is directly connected with power supply 8, electric heater in order to thaw ice and snow, the high temperature shelves work of automatic cleaning air filter cleaner net; Be provided with between described electric heater 2 and air-strainer 4 and use so that the backward outer elbow 3 dripped of ice dissolution, described elbow 3 is the structure of bending 30 ° downwards.
Described electric heater 2 adopts ring electric heater, 24V direct current supply, point high/low temperature two grades heating; Low temperature shelves heating power is 500W, for improving intake temperature; High temperature shelves heating power is 1000W, melts the ice and snow on air cleaner gauze for heating air inlet simultaneously.
As shown in Figure 2, circuit connects: electric current is by DC24V power supply 8 negative pole, by after key switch 9 point of two-way, one road flows through control box 10 and to wire back source 8 positive pole, an other road flows through resistance R, electric heater 2 flows back to power supply 8 positive pole, wherein in parallel with resistance 11 by execution switch 12, controls the high and low shift power of electric heater 2, vacuum pressure transmitter 7 connects on control box 10, for control box 10 provides current signal.
Working principle is as follows:
1, before diesel engine plays machine, close switch 9, electric heater 2 low temperature shelves, work, improves intake temperature, ensures that diesel engine can quick starting.After diesel engine starting success, electric heater 2 low temperature shelves continuous firing is used for heating air inlet, Optimizing Combustion, reduces the discharge of diesel engine solid particulate matter, extends diesel engine object in working life.
2, close switch, control box obtains electric.Vacuum pressure transmitter 7 is powered by control box 10, is constantly control box 10 fed-back current signals.When air-strainer net 1 is blocked by ice and snow, both intake elbow intake vacuum was higher than 3.5kPa, vacuum pressure transmitter 7 exports 12mA current signal, control box 10 receives and processing signals, execution switch 12 is closed, electric heater 2 high temperature shelves are opened, and start to thaw ice and snow, and then reach the object of automatic cleaning air filter cleaner net 1; After ice and snow is disposed, when intake vacuum recovers normal value 2kPa, vacuum pressure transmitter 7 feeds back the current signal of 6mA to control box 10, and control box 10 conveys a message and makes execution switch 12 open circuit, electric heater 2 high temperature shelves automatically switch to low temperature shelves, and then reach deicing object.
