Embodiment
The utility model is described in further details with specific embodiment below in conjunction with the accompanying drawings.As shown in figure 1, a kind of base
In the air cleaning unit of diesel particulate trap, including housing 14, axial flow blower 11 and diesel particulate trap 4；Bavin
Oil machine grain catcher 4 is located at the bottom in housing 14, and its air inlet is connected to the opening of the bottom of housing 14, and gas outlet is connected to
The big opening end of horn mouth 9, the osculum end of horn mouth 9 is connected to the air inlet of axial flow blower 11, axle stream by rubber bellows 10
Blower fan 11 is located at the top in housing 14, and its gas outlet is connected to the opening at the top of housing 14.
Wherein, diesel particulate trap（DPF Diesel Particulate Filter）It is to remove in diesel engine vent gas
The important device of particulate matter, the particle size of its port of export can be controlled in Nano grade., can using DPF architectural characteristic
To use it for the indoor PM2.5 for crossing micron level in air filtering.Its structure, material are respectively wall-flow type and cordierite.
The DPF sizes of the present embodiment are：Diameter 144mm, high 155mm, are positioned on plastic casing, housing lower end is provided with out
Bore dia is 140mm, and installs a diameter of 144mm screen pack 3, pre-filtering of entering to air in perforate upper end.
Axial flow blower has high, medium and low three gears, and perforate size in housing upper end matches with axial flow blower outlet size；
Axial flow blower is connected with horn outlet by rubber bellows.
Axial flow blower is used for the directed flow for strengthening air；Horn mouth is used for the connection of DPF and rubber bellows；Rubber is stretched
The retractility of the draw is easy to DPF handling.
Axial flow blower is mainly made up of parts such as impeller, stator, diffuser pipe, motor, when the impeller is rotated, gas from
Air inlet raises the energy of gas by the pushing of impeller blade, then flows into stator axially into impeller.Stator will
Deflection air-flow is changed into axial flowing, while introducing gas into diffuser pipe, gas kinetic energy further is converted into pressure energy, finally drawn
Enter working line.
The air inlet of the diesel particulate trap 4 of the present embodiment and the junction of the bottom opening of housing 14, and gas outlet
It is equipped with the junction of horn mouth 9 for sealed rubber ring 8, rubber ring 8 is externally provided with the elastic rubber band for fastening.Rubber
Ring internal diameter is 146mm, a length of 10mm.
The outer wall of diesel particulate trap 4 is fixed on the madial wall of housing 14 by Y type supports in the present embodiment.During installation
Y type supports one end is arranged on to the interior both sides of material shell body, and slided along chute, DPF both sides are fixed.
The bottom of the present embodiment housing 14 is additionally provided with universal wheel 1, is easy to flexibly move indoors.
Assembling and application method are as follows：
The first step：Universal wheel 1 is installed on plastic casing；
Second step：Axial flow blower 11 is installed to the upper end of plastic casing；
3rd step：The metal filtration that DPF is installed into housing is online, and blend rubber ring and elastic force elastic band are by DPF entrances
End sealing；
4th step：Y types support is arranged on to the interior both sides of plastic casing, and slided along chute, DPF both sides are fixed；
5th step：The entrance of rubber bellows and axial flow blower is connected, and rubber ring and elastic force elastic band are gone out DPF
The sealing of mouth end；
6th step：Connect power switch and driving switch；
7th step：Plug in, turn on the power switch, you can normal operation；
8th step：Gear-adjustable switchs to change the flow of DPF entrances.
The course of work is as follows：Air enters DPF through screen pack 3, and DPF filtered out the PM2.5 of micron level in air filtering
Afterwards, clean air is extracted out through rubber bellows by axial flow blower, is discharged into interior.
