Description
Technical field
The utility model is related to a kind of air prefilters to set, more particularly to a kind of engineering machinery, agricultural machinery air
Prefilter.
Background technology
Engine is the core of motor vehicles, therefore is essential to the safeguard measure of engine.Its is hollow
Air cleaner can effectively remove the granulometric impurity in air, and then reduce abrasion of the impurity to engine interior in air.It is logical
It crosses and is further added by air prefilter on the engine not only and can extend the service life of air cleaner, reduce and enter gas handling system
Dust and impurity, but also allow air cleaner keep clean and keep the operation of engine more powerful, while improve start
Machine performance reduces downtime and operation cost.
The principle of air prefilter is that the suction by engine is used so that air-flow is generated rotation under the action of blade at present
Turn, the dust in air gets rid of the edge to prefilter shell under the influence of centrifugal force, and ash is driven under the action of eddy flow fan
Dirt makes dust from the dust exhausting hole discharge on shell；But since engine speed when engine uses is different, lead to air inflow
It is different；The rotating speed of eddy flow fan can also change with the size of air inflow, and when the rotating speed of engine is too low, (such as engine is protected
Hold idling mode), the rotating speed of eddy flow fan then cannot achieve, and the dust for entering air prefilter is discharged, and influences the thick of prefilter
Filter efficiency.
Utility model content
A kind of the technical problem to be solved by the utility model is to provide coarse filtration effects good, eddy flow fan stabilization of speed height
Imitate rotor air prefilter.
In order to solve the above technical problems, the utility model provides a kind of efficient rotor air prefilter, bottom is included at least
Seat, shell, eddy flow fan, pedestal are outward extended with escape pipe, the endoporus of escape pipe with cavity, pedestal is formed inside housing combination
It is communicated with cavity, several deflectors is also distributed on pedestal, the external air admission hole with cavity of connection is equipped between adjacent baffle,
Eddy flow fan is mounted in cavity, and side wall of outer shell is provided with the dust exhausting hole communicated with cavity；
Further include motor, eddy flow fan is mounted on the output shaft of motor, the axis of the dust exhausting hole of shell along motor output shaft
Line circle distribution.
After such structure, this efficient rotor air prefilter can be made not influenced by engine speed, will revolved
The rotating speed of flow fan is controlled in a rational range, this efficient rotor air prefilter is made to reach better coarse filtration effect.
For the clearer technology contents for understanding the utility model, this efficient rotor air prefilter is referred to as below
This prefilter.
Separating pipe is additionally provided in the cavity of this prefilter, for separating pipe side end sleeve on escape pipe, separating pipe is another
Side end is stretched out to eddy flow fan directional；After such structure, it is direct from air admission hole that a part of dust, impurity can be obstructed
It is discharged through escape pipe.
It is provided with the groove for agreeing with separating pipe end side tube wall on the blade of the eddy flow fan of this prefilter；Using in this way
Structure after, make the maximum length of separating pipe, avoid the gap of dust, impurity between separating pipe and eddy flow fan directly into
Enter escape pipe.
The air inlet position of the pedestal of this prefilter is equipped with filter screen；After such structure, filter screen can be pre-
First filter the larger foreign matter such as a part of long fibre, leaf.
Strength hose clamp is banded with outside the escape pipe of this prefilter；After such structure, strength hose clamp facilitates outlet
Tube end is connected to the air filter air entraining pipe on engine.
Description of the drawings
Fig. 1 is the sectional view of the structural schematic diagram of this prefilter embodiment.
Specific implementation mode
(succinct for view, the hatching of shell 2 is omitted in Fig. 1) as shown in Figure 1.
This prefilter includes pedestal 1, shell 2, eddy flow fan 5 and motor 4.
Pedestal 1 is substantially in the form of annular discs, and 1 center of pedestal is extended with escape pipe 11, and the endoporus of escape pipe 11 runs through pedestal 1
Upper and lower end face, 11 lower end of escape pipe is banded with strength hose clamp 12, and the lower end of escape pipe 11 passes through strength hose clamp 12 and hair
Air filter air entraining pipe in motivation is connected to, and multiple deflectors 14 are additionally provided on the region that pedestal 1 is in except escape pipe 11, multiple to lead
Flowing plate 14 is distributed along 11 uniform circular of escape pipe, and the air admission hole for being connected to external and cavity 3 is equipped between adjacent baffle 14 (in figure
Do not indicate), air inlet position is covered with filter screen 13.
The flat tubbiness of the generally lower face of shell 2 opening, shell 2 combine internal formation cavity 3 with pedestal 1, outside
2 side wall of shell is provided with the dust exhausting hole 21 communicated with cavity 3.
Motor 4 is fixed on 2 outer wall upper surface of shell, and the output shaft of motor 4 stretches into cavity 3, and eddy flow fan 5 is mounted on electricity
On the output shaft of machine 4, the voltage DC24V of motor 4, rotating speed 1800r/min, the axis of the dust exhausting hole 21 of shell 2 along 4 output shaft of motor
Line circle distribution, escape pipe 11 are on the downside of the axial direction of 4 output shaft of motor.
Separating pipe 6 is additionally provided in cavity 3,6 side end sleeve of separating pipe is mounted in the endoporus top of escape pipe 11, separating pipe 6
End side is stretched out to 5 direction of eddy flow fan, is provided on the blade of eddy flow fan 5 and is agreed with 6 end side tube wall of separating pipe
Groove 51.
In use, motor 4 drives eddy flow fan 5 to turn with the rotating speed of 1800r/min or so by external power drives
Dynamic, external air is entered by the air inlet of pedestal 1 in cavity 3, and eddy airstream can be formed in cavity 3.Due in air
The impurity (such as dust, rainwater, snow sundries) mixed is rotated with the eddy airstream entered in cavity 3, and because impurity
Rotary inertia is more than the rotary inertia of air, therefore most of impurity should be detached with air under the influence of centrifugal force, be got rid of to shell
Body edge；Impurity, which is hit with eddy flow fan 5 to 3 side wall of cavity, to be moved, and such impurity will be discharged by the dust exhausting hole 21 of shell 2
Outside this prefilter.
Above-described is only a kind of embodiment of the utility model, it is noted that for the ordinary skill of this field
For personnel, without departing from the principle of this utility model, several variations and modifications can also be made, these also should be regarded as
Belong to the scope of protection of the utility model.
