Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As depicted in figs. 1 and 2, the dust excluding hood 1 including tubular, with the partition of Openworks shape at the upper end opening of dust excluding hood 1
One 11, with the partition 2 12 of Openworks shape at the lower ending opening of dust excluding hood 1, there is a connection ring on the middle part inner wall of dust excluding hood 1
13, be connected with a dust-removal cloth-bag 2 in connection ring 13, the rims of dust-removal cloth-bag 2 are connected with connection ring 13, partition 1 and every
A slide bar 21 is fixedly installed between plate 2 12, the bottom of dust-removal cloth-bag 2 has a notch, and indentation, there is connected with sliding sleeve 22, sliding
Set 22 is slidably connected on slide bar 21, and the tension spring 23 of connection sliding sleeve 22 and partition 1 is arranged on slide bar 21；Partition 1
Top is fixedly installed a shield 31, and shield 31 is cell structure, and the top and bottom of shield 31 are open, partition one
It is connected between 11 and shield 31 by a guide post 32, a guide rod 33 is inserted in guide post 32,33 upper end of guide rod is solid
Surely the valve 34 of opening of 31 lower end of shield can be covered by being provided with one, and a reset is connected between valve 34 and guide post column
Spring 35 is provided with an impeller 41 at the upper end opening of shield 31, and impeller 41 is connected with the output shaft of a driving motor 42；It is anti-
There is a flexible caplet 5, caplet 5 is tubular, and two openings of caplet 5 are respectively and above and below shield 31 in shield 31
Two openings correspond to.
By impeller 41 to air blast is carried out in shield 31, expand 5 deformation of caplet, air pressure reaches multiple in shield 31
When the pretightning force of position spring 35, valve 34 is opened, and is allowed airflow into dust cover, and impact dust-removal cloth-bag 2, is made miscellaneous in air-flow
Matter is by dust-removal cloth-bag 2 every filter.
It is not difficult to find out that increasing the stream pressure entered in dust excluding hood 1, valve 34 due to being provided with valve 34 and caplet 5
When closing, larger negative pressure is formed, and there are biggish airflow fluctuation, enable the shake by a relatively large margin of dust-removal cloth-bag 2 and larger
The shake of frequency avoids dust-removal cloth-bag 2 from blocking to shake out to the impurity that may be adhered on 2 inner wall of dust-removal cloth-bag.
In dust removal process, dust-removal cloth-bag 2 is acted on by stream pressure, stretches tension spring 23, so that dust-removal cloth-bag 2 is had bigger
Breathing area be located at the lower section of connection ring 13, after dedusting, by the pulling force effect of tension spring 23, dust-removal cloth-bag 2 is located at
The top of connection ring 13, the i.e. inner surface of dust-removal cloth-bag 2 are in upwards and to present convex, are accumulated on 2 inner wall of dust-removal cloth-bag originally
Dust and impurities can be by being deposited at the position of connection ring 13 again, thus will not be in the inner wall long-time heap of dust-removal cloth-bag 2
Product, avoids dust from being bonded on the inner wall of dust-removal cloth-bag 2 and cloth bag is caused to block.
It is connected between slide bar 21 and sliding sleeve 22 by spline.By spline, dust-removal cloth-bag 2 can be prevented to fluctuate up and down
It is distorted in journey, keeps the planarization of dust-removal cloth-bag 2, prevent dust-removal cloth-bag 2 from being pullled by tension spring 23 and be damaged.
Slide bar 21 is arranged with a bellows, and tension spring 23 is located in bellows.The setting of bellows can prevent the product of tension spring 23
Ash.
A cleaning window is offered on dust excluding hood 1, cleaning window is located on connection ring 13, clears up at window and detachably connect
It is connected to a cover board.When cloth bag needs to clear up, it is only necessary to cleaning window is opened, cloth bag part is pulled to cleaning window, it can be right
Dust-removal cloth-bag 2 is tentatively cleared up.
The upper and lower surfaces of connection ring 13 are inclined inclined-plane inwardly.13 one side of connection ring is convenient for dust removing cloth
On the other hand the dismounting of bag 2 by the inclined mode of upper and lower surface, can prevent dust accretions, increase the guiding to air-flow.
