The important measures of power noise.In order to reduce noise, at the tail gas aerofluxuss of diesel fork lift truck, it is connected with acoustic filter, existing fork truck
On acoustic filter be usually by the global design of fork truck producer, the cylinder of acoustic filter is generally large, its by be installed in two ends
Frame is fixed on fork truck.
But with gradually stepping up of non-road engines discharge standard, increasing electromotor producer joins on product
Ternary catalyzing unit is had to be used for purifying vehicle tail gas, the main harmful gass such as co, hc and nox that vehicle exhaust is discharged pass through oxidation
It is changed into harmless carbon dioxide, water and nitrogen with reduction.Thus leading to existing monomer acoustic filter cannot meet
Car load is using needs, if directly increase on the existing fork truck with ternary catalyzing unit installing acoustic filter, because fork truck is empty
Between limited, cause crowded and there is potential safety hazard.If the monoblock type three-element catalyzing muffler that buying producer provides, relatively costly
And need in addition to pay high die sinking expense.
Utility model content
In order to solve the above problems, this utility model provides the diesel fork lift truck that a kind of split type tail gas clean-up is eliminated the noise, and solves
Fork truck tail gas clean-up and the two fold problem eliminated the noise, and reach saving space and environment protection emission requirement.
The diesel fork lift truck that a kind of split type tail gas clean-up is eliminated the noise, the three-element catalytic be connected including acoustic filter and with tail gas
Device, described acoustic filter includes silencer cylinder, and the inlet end of silencer cylinder is connected with intake elbow, outlet side is connected with aerofluxuss
Tail pipe, the outlet side of described ternary catalyzing unit is connected with described intake elbow, and the two ends of described silencer cylinder are installed with respectively
Mounting bracket, and by mounting bracket, silencer cylinder is arranged on vehicle frame；It is installed with upwards outside described silencer cylinder
The heat shield being obliquely installed, described ternary catalyzing unit is inclined between silencer cylinder and heat shield, and same with heat shield
Direction is obliquely installed.
Scheme further, the outlet side of described ternary catalyzing unit is connected by adpting flange with described intake elbow.
Scheme further, the line of centres of described ternary catalyzing unit and silencer cylinder end tilts 22 ° to frame outside.
Scheme further, the mounting bracket positioned at silencer cylinder two ends is in that diagonal is arranged.
This utility model by ternary catalyzing unit and silencer cylinder using being inclined in fork truck tailstock, silencer cylinder
Intake elbow be connected with the port of export of ternary catalyzing unit, forklift engine tail gas through ternary catalyzing unit purification after enter back into noise elimination
Carry out noise reduction, final purification, the tail gas of noise reduction are discharged through tailpipe, greatly reduce tail gas to environment in device cylinder
Atmospheric pollution and noise pollution.It is welded with heat shield in silencer cylinder outer inclination to completely cut off hot air reflux.
Arrange that the mounting bracket at its its two ends and forklift frame are fixedly connected in silencer cylinder by diagonal, make
Its fixing-stable, thus reduce vibration and the noise of exhaust system assembly；In addition, ternary catalyzing unit and silencer cylinder are in fork truck
To 22 ° of arrangements of outer incline in tailstock space, utilize the inner space of fork truck tailstock and counterweight from face to greatest extent, reach finger simultaneously
Fixed soundproof effect.
This utility model has the advantages that compared to prior art
1st, by acoustic filter and ternary catalyzing unit separate design, make full use of the inner space of fork truck tailstock and counterweight, and real
The double effectses having showed to tail gas clean-up and having eliminated the noise, effectively meet discharge standard, and can meet the further demand of client.
2nd, will be arranged apart to acoustic filter and ternary catalyzing unit, it is to avoid the higher die sinking expense that monoblock type catalytic muffler brings
With.
