Embodiment
Technological scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
As Fig. 1, shown in Fig. 2, a kind of self-cleaning air-strainer, comprise upper cover 1, lower cover 2, and outer net 3 between upper cover 1 and lower cover 2 and Intranet 4, filter paper 5 is provided with between outer net 3 and Intranet 4, the bottom of upper cover 1 is provided with the cleaning device 6 of the outer side surface for clean filter paper 5, cleaning device 6 comprises the flexible rod 62 that can move up and down along the axial direction of filter paper 5 be connected with upper cover 1, and the drive unit 61 for driving flexible rod 62 to move up and down, the end of flexible rod 62 is provided with the bristle 63 matched with filter paper 5, bristle 63 is between outer net 3 and filter paper 5.
Self-cleaning air-strainer of the present invention, by being provided with filter paper 5 between outer net 3 and Intranet 4, the bottom of upper cover 1 is provided with the cleaning device 6 of the outer side surface for clean filter paper 5, cleaning device 6 comprises the flexible rod 62 that can move up and down along the axial direction of filter paper 5 that is connected with upper cover 1 and the drive unit 61 for driving flexible rod 62 to move up and down, the end of flexible rod 62 is provided with the bristle 63 matched with filter paper 5, and bristle 63 is between outer net 3 and filter paper 5; Under its working state, can bristle 63 be driven to move up and down by flexible rod 62 at any time to clean the outside of filter paper 5, without the need to shutdown operation, the dust of the accumulation outside automated cleaning filter paper 5 can be realized, also without the need to dismantling filter paper, this will greatly reduce and safeguard intensity, make to safeguard more timely, and then ensure air intake efficiency; And this structure is simple, fabricating cost is low.
Preferably, this self-cleaning air-strainer also comprise be arranged at Intranet 4 inner side for detecting the air volume test sensor of the air intake state of self-cleaning air-strainer, and the bottom being arranged at upper cover 1 is for receiving the controller of the Detection Information of air volume test sensor, drive unit 61, air volume test sensor are all connected with controller.When engine operation, this self-cleaning air-strainer is also in running order, because engine charge is interrupted, the air thus entering this air-strainer is also interrupted, at this moment utilizes air volume test sensor can the air intake state of this self-cleaning air-strainer of Real-Time Monitoring, to determine its working state, when motor air intake, self-cleaning air-strainer is air intake state, otherwise, when engine stop air intake, self-cleaning air-strainer is for stopping air intake state; Utilize air volume test sensor that Detection Information is passed to controller, controller is started working according to the Detection Information accessory drive 61 received or is quit work.Preferred further, in the present embodiment, when air volume test sensor detects this self-cleaning air-strainer for stopping air intake state, controller accessory drive 61 is started working, drive unit 61 drives flexible rod 62 to move up and down, also namely flexible rod 62 drives bristle 63 to move up and down, and then realizes the automated cleaning to filter paper 5.This just can control cleaning device 6 well and clean under the state of this self-cleaning air-strainer not air intake, in order to avoid delay its normal air intake, and then the air intake of motor can be ensured, and utilize coordinating of this air volume test sensor and controller, making to control comparatively accurately, can realize without the need to artificially participating in.
Certainly, the air intake state detecting this self-cleaning air-strainer except utilizing air volume test sensor with carry out in good time filter paper 5 clean except, this self-cleaning air-strainer can also by arranging timer to realize.Now make timer be connected with controller, utilize timer to control to drive decoration 61 start by set date or stopping making controller, carry out automated cleaning in the punctual outside to filter paper 5 in the given time to make cleaning device 6.Clean by timing, effectively can avoid the serious laying dust of filter paper 5, and then reduce each clean difficulty, improve cleaning quality.
Especially, when the laying dust brush outside filter paper 5 falls behind by bristle 63, these dusts fall naturally, directly fall into the surface of lower cover 2, and if the surface of lower cover 2 for a long time overstock dust, when this self-cleaning air-strainer air intake, dust can be adsorbed by filter paper 5 again, and then affects air inlet effect.For avoiding the generation of above-mentioned situation, the bottom of lower cover 2 is provided with the dust accommodation box 7 removably connected, and the bottom of lower cover 2 is provided with the dust via hole be dropped through for the dust on filter paper 5, and dust via hole is corresponding with dust accommodation box 7 to be arranged.At each bristle 63, the laying dust brush in the outside of filter paper 5 is fallen behind dust and will directly fall into dust accommodation box 7, dust in dust accommodation box can be cleaned out when carrying out plant maintenance, so just can ensure this self-cleaning air-strainer work long hours unaffected.
In the present embodiment, for increasing incoming air area, filter paper 5 has multiple folded slot.Correspondingly, the bottom of upper cover 1 is provided with the support ring removably connected, and the bottom of support ring is provided with multiple flexible rods 62 of annular arrangement, and the quantity of the quantity of flexible rod 62 and the folded slot of filter paper 5 adapts, and bristle 63 is arranged in folded slot.And bristle 63 coordinates just with the outer side surface of filter paper 5, to reach completely clean object.In addition, in order to make flexible rod 62 to match with the folded slot of filter paper 5 neatly, flexible rod 62 and support ring are for removably connecting, when folded slot is more, more flexible rod 62 can be installed, and when folded slot is less, the flexible rod 62 of a part can be disassembled.
Be provided with sealing rubber pad between the upper cover 1 of this self-cleaning air-strainer and filter paper 5 and between lower cover 2 and filter paper 5, effectively can ensure the air intake quality at the two ends up and down of filter paper 5, avoid dust to enter.
This self-cleaning air filtering device structure is simple, and easy to use.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present invention, and these modes all will fall within protection scope of the present invention.
