Specific embodiment
The utility model is further described with the following Examples.
A kind of air filter back-blowing device of the utility model, as shown in figures 1 and 3, back-blowing device are mounted on air
On filter, air filter includes babinet 1 and three cylindric filter screens 4 being installed in babinet 1, the side wall of babinet 1
Bottom offers air inlet, and babinet 1 and the top side wall of air inlet face offer gas outlet.Air with dust is from babinet
1 air inlet flows into babinet 1 (in Fig. 1 and Fig. 3 shown in arrow), and then after the filtering of strainer 4, clean air is from babinet 1
Gas outlet outflow.In addition, to prevent clean air by the air pollution with dust, by installing isolation board 2 in babinet 1
Babinet 1 is given as soil chamber and toilet, the air inlet of babinet 1 is located at soil chamber, and the gas outlet of babinet 1 is located at toilet.
The gas outlet of each filter screen 4 is located in toilet, and isolation board 2 is concordant with the end face of the gas outlet of filter screen 4, can increase in this way
Filter screen 4 is added to filter the flow of dust air, and then promotes filter efficiency.
As shown in Figures 1 to 4, back-blowing device is installed in toilet, and back-blowing device, which includes cover board 3, can seal single mistake
The cover board 3 of the gas outlet of strainer 4 and the blowback air source part 5 that can continue to provide blowback air-flow, blowback air source part 5 are connected with blowback
Tracheae 6, the outlet side of blowback tracheae 6 are inserted into across cover board 3 in the filter screen 4 that gas outlet is sealed by the cover board 3.It in this way can be right
The filter screen 4 carries out prolonged blowback cleaning, and the effect of blowback cleaning is good.And driver 7 can drive cover board 3 from one
The gas outlet of filter screen 4 is transferred to the gas outlet (as shown in figures 1 and 3) of another filter screen 4, the mistake not sealed by cover board 3
Strainer 4 can work on, it is ensured that the cleaning of blowback one by one can be carried out to each filter screen 4 at any time in the case of without shutting down,
Ensure the dust collection efficiency and pick-up performance of entire filter, also extend the service life of each filter screen 4, reduce filter screen
4 consumables cost and maintenance cost.
When carrying out blowback cleaning to filter screen 4, the air-flow to prevent from flowing up jacks up cover board 3, and then reduces anti-
The air pressure blown influences the effect of blowback cleaning, and the edge part in the gas outlet of filter screen 4 installs finite place piece 8, and locating part 8 is set
There is the limiting slot of arc, in the state of the gas outlet for sealing filter screen 4 in cover board 3, the part edge of cover board 3 is inserted into limiting slot
In so that the air-flow of blowback just can be all flowed to outside it from the inside of filter screen 4, and then will be attached to outside filter screen 4
Dust and impurity are blown off so that the flow of filter screen 4 and pressure drop restore normal.
In the present embodiment, driver 7 is motor.The pivot center of cover board 3 is located at the circumscribed of three columnar filter screens 4
On the round center of circle, the pivot center of the shaft of driver 7 is overlapped with the pivot center of cover board 3 so that driver 7 drives cover board 3
During rotation, cover board 3 can be transferred to the gas outlet for covering another filter screen 4 (as schemed from the gas outlet for covering a filter screen 4
Shown in 1 and Fig. 3), can blowback cleaning be carried out to each filter screen 4 one by one in this way in the case of without shutting down.
In the present embodiment, as shown in figures 1 and 3, locating part 8 and cover board 3 are all mounted on above isolation board 2, driver 7
Between blowback air source part 5 and cover board 3.Isolation board 2 plays supporting role to back-blowing device.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model rather than to this reality
With the limitation of novel protected range, although being explained in detail with reference to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the utility model, without departing from this
The spirit and scope of utility model technical solution.
