Description
Technical field
The utility model belongs to engineering machinery field, relates to the vent systems of a kind of excavator, particularly a kind of middle-size and small-size excavator.
Background technique
As shown in Figure 3, existing middle-size and small-size excavator vent systems, comprises baffler 5, telescopic outlet pipe 7 and turbocharger of motor 1, and the suction tude 4 of baffler 5 is open flume type pipeline.Telescopic outlet pipe 7 one end are connected with turbocharger of motor 1 relief opening, and the other end is inserted into tracheae 4, fixing with baffler reducing clip 6, have formed the vent systems of middle-size and small-size excavator.
Middle-size and small-size excavator is with respect to large excavator, and its space is little, and turbocharger of motor 1 relief opening and baffler 5 spacing are little, generally adopts telescopic outlet pipe 7 to connect.But telescopic outlet pipe 7 is easily given a shock impact, the easy deformation gas leakage in joint.If run into the situations such as oil inflame is insufficient, exhaust resistance is excessive, the gas leakage of outlet pipe place, telescopic outlet pipe 7 can over-emitting black exhaust.This can affect vent systems overall performance, unfavorable to product performance.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of vent systems of middle-size and small-size excavator of difficult gas leakage.
To achieve these goals, the technological scheme that the utility model is taked is:
The vent systems of described middle-size and small-size excavator, comprise engine turbine pressure-increasing machine and baffler, described baffler is provided with suction tude, and the relief opening of described engine turbine pressure-increasing machine is connected with described suction tude by bellows, and described suction tude is connected by flange with described bellows.
Adopt technique scheme, simple in structure, adopt flange to connect the length that just can shorten suction tude, the air inlet mouth of pipe is increased to the distance of the relief opening of engine turbine pressure-increasing machine, thereby can use the bellows that is difficult for gas leakage to connect, reduce the possibility of gas leakage.Bellows has flexibility, is given a shock not fragilely, and shock resistance is good, long service life.

Being labeled as in figure:
1, turbocharger of motor; 2, bellows; 3, flange; 4, suction tude; 5, baffler; 6, baffler reducing clip; 7, telescopic outlet pipe; 8, dividing plate; 9 plasma reactors; 10, purifying net.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technological scheme.
As shown in Figure 1, the utility model provides a kind of vent systems of middle-size and small-size excavator, comprises turbocharger of motor 1, bellows 2 and baffler 5.Baffler 5 is provided with a suction tude 4, is welded with flange 3 at the mouth of pipe place of suction tude 4.The open flume type duct length of this suction tude 4 in is compared to existing technology shorter, and distance between suction tude 4 and the relief opening of turbocharger of motor 1 is increased, and can use bellows 2 to connect between the two.Compare telescopic outlet pipe, the sealability of bellows 2 is better, has solved the problem of vent systems gas leakage and then the black smoke of emerging.Simultaneously bellows 2 also has certain flexibility, is given a shock not fragilely, and shock resistance is good, long service life.
Bellows 2 one end are also welded with flange 3, and bellows 2 links together by flange 3 with suction tude 4.Suction tude 4 adopts welding manner to be connected with flange 3 with bellows 2, is not only connected firmly but also good airproof performance.Between two flanges 3, be provided with high-temperature resistant seal ring, can prevent flange 3 joint gas leakage after connection, during due to operation, the very high therefore seal ring of temperature of outlet pipe must have resistance to high temperature.The relief opening of bellows 2 the other ends and turbocharger of motor 1 is by V-type clip connected, and simple and reliable have enough sealings simultaneously.
In baffler 5, be provided with dividing plate 8.Dividing plate 8, to being noise elimination part between suction tude 4, is inside established the noise that silencer produces for reducing exhaust; Dividing plate 8, to being purification portion between the relief opening of baffler 5, is inside established exhaust gas cleaner for cleaning of off-gas.Described exhaust gas cleaner comprises plasma reactor 9 and purifying net 10.Bottom in purification portion is fixed with fixed base, and plasma reactor 9 is arranged on fixed base, and the suction tude of plasma reactor 9 is communicated to noise elimination part through dividing plate 8.The effect of dividing plate 8 is to prevent that the tail gas not purifying in noise elimination part from just entering purification portion without exhaust gas cleaner.Therefore, between the housing of dividing plate 8 and baffler 5 and the suction tude of plasma reactor 9, all to seal.In fixed base, be provided with electric control box, in electric control box, be provided with the electronic control system of plasma reactor 9.Toxic gas in plasma reactor 9 energy cleaning of off-gas, can also smash the solid particle containing in tail gas, has good cleaning of off-gas effect.
Purifying net 10 is fixed on the relief opening of plasma reactor 9, and purifying net 10 uses asbestos fiber net, and wherein absorption has conversion catalyst.In the time of tail gas process purifying net 10, solid grain contamination wherein can be adsorbed on purifying net 10, and conversion catalyst can impel the toxic gas in tail gas to be converted into innocuous gas, has further reduced the pollution that tail gas produces.
