Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Referring to FIG. 1, FIG. 2 and FIG. 4, be a kind of pre-filtering deduster disclosed by the utility model, mainly include collection chamber 11,
13 three parts of inlet plenum 12 and dust storage chamber.Collection chamber 11, inlet plenum 12 and dust storage chamber 13 are linked in sequence from top to bottom, mutually solely
It is vertical.Air inlet 14 is evenly equipped on the outer wall of inlet plenum 12, outside air is entered in inlet plenum 12 by air inlet 14.
Cyclone dust collectors are mounted in inlet plenum 12, and gas output end is connected to collection chamber 11, gas input with into
Gas chamber 12 is connected to, and dust output end is connected to dust storage chamber 13.Air in inlet plenum 12 enters whirlwind from gas output end and removes
The inside of dirt device, the dust filtered out are fallen in dust storage chamber 13 by dust output end, defeated by gas by filtered air
Outlet enters collection chamber 11.Multiple cyclone dust collectors are installed, these cyclone dust collectors are around inlet plenum 12 in inlet plenum 12
Center line circular array can further increase filter effect.
Central tube 14 is one section of round tube, and sequence from low to uper part passes through dust storage chamber 13 and inlet plenum 12 is connected to collection chamber 11,
The air of collection chamber 11 is flowed out by central tube 14.The top surface of collection chamber 11 is cambered surface, and inside is fixed with a guiding centrum
6, guiding centrum 6 is located at the surface of central tube 14, and sectional area is gradually reduced on the direction close to central tube 14, can incite somebody to action
The air of cyclone dust collectors discharge is imported into central tube 14, it is avoided to gather at the center of collection chamber 11, improves air stream
Speed.
The lower end of central tube 14 is fixed with one section of connecting tube 3, is provided with a plurality of contracting seam 4 on the side wall of connecting tube 3, contracting seam 4 with
The centerline parallel of connecting tube 3, lower end are connected to the lower end of connecting tube 3, are open end.When being squeezed by external force, connecting tube 3
It can deform, what is be bonded with engine air inlet tube is even closer.
Referring to Fig. 5 to Fig. 6, the main body of cyclone dust collectors is operating room 21, and the shape of operating room 21 is cylinder.Air inlet pipe
22 are located on the side of operating room 21, and air is entered inside all operating rooms 21 by air inlet pipe 22.Ash releasing tube 23 is located at operating room
On 21 bottom surface, shape is cone.A part of ash releasing tube 23 is located at outside operating room 21, and another part is located at operating room 21
It is internal.After air enters in air inlet pipe 22, the flow velocity of gas and the flow velocity of impurity are identical, but impurity is since quality is big, because
The centrifugal force that this is subject to is bigger.The motion profile of gas and impurity is curve in air inlet pipe 22, thus impurity can want close into
The direction of 22 wall of tracheae is mobile and rubs therewith, and the flow velocity that friction rear impurity occurs is slack-off, can be along in operating room 21
Wall is slipped in ash releasing tube 23 and eventually falls into dust storage chamber 13.Air flows into collection chamber 11 from exhaust pipe 24.
Referring to Figure 1 and Figure 3, multiple buckles 51 are installed, on the outer wall of corresponding inlet plenum 12 on the outer wall of dust storage chamber 13
Multiple connecting holes 52 are provided with, the hook on buckle 51 can be hooked on inlet plenum 12 by connecting hole 52, connect dust storage chamber 13
In the lower section of inlet plenum 12.Corresponding, the junction of cyclone dust collectors and dust storage chamber 13 is fixed with sealing ring 7.Because of dust storage chamber
13 can remove, so the junction of cyclone dust collectors and dust storage chamber 13 there are gap, needs to block up gap using sealing ring 7
Firmly, leakproofness is improved.
The implementation principle of the present embodiment are as follows:
By 3 sets of connecting tube in the air inlet pipe of engine, the fixation members such as the clip on 3 outer wall of connecting tube are then tightened.
During being somebody's turn to do, due to the presence of contracting seam 4, connecting tube 3 can be deformed, and even closer is fitted on engine air inlet tube.
In the course of work, outside air enters inlet plenum 12 by air inlet 14, then enters work by air inlet pipe 22
Room 21.During into air inlet pipe 22 and operating room 21 are crossed, is separated in foreign substances from air, collection is fallen on by ash releasing tube 23
In dirt room 13, air is flowed in collection chamber 11 by exhaust pipe 24.
Air in collection chamber 11 is flowed along the arc top surface of collection chamber 11, under the action of being oriented to centrum 6 in inflow
Then heart cylinder 15 flows in the air inlet pipe of engine by central tube 15.
After a period of work, it needs to open buckle 51, dust storage chamber 13 is removed, clear up the dust of the inside, cleaning is completed
After reinstall.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
