The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, the pulse jetting deashing device of the disclosed pulse bag type dust collector of the utility model embodiment comprises pulse valve 10, divides gas bag 11 and gas vacuum tank 15.Pulse blast pipe 13 in the described pulse valve 10 is communicated with described gas vacuum tank 15; Pressure by air pressure in the described gas vacuum tank 15 is higher than the operating pressure of deduster, less than pulse jetting deashing pressure.Described deduster operating pressure is 0.8 to 6MPa.
Introduce the course of work and the operation principle of the pulse jetting deashing device of this pulse bag type dust collector below: during this pulse bag type dust collector work, after connecting the body air inlet pipe 22 of calming the anger, Compressed Gas enters rear gas chamber 17 by pulse valve throttle orifice 19, under the effect of described rear gas chamber 17 pressure and pulse valve armature component 16, pulse valve diaphragm 20 is adjacent to pulse jetting deashing pipe air inlet 21, and pulse valve is in closed condition.After described pulse valve 10 energisings, described pulse valve armature component 16 moves backward, and the blast pipe 13 of pulse valve rear gas chamber 17 is opened.Thereby the gas of the discharging of described pulse valve rear gas chamber 17 enters in the described gas vacuum tank 15.Chamber 17 rapid decompressions are moved behind the described pulse valve diaphragm 20 behind the described pulse valve, and the Compressed Gas in described minute gas bag 11 enters by pulse jetting deashing pipe air inlet 21 and carries out pulse jetting deashing in the pulse jetting deashing pipe 12.At this moment, pulse valve 10 is in opening.Because the Pneumatic pipe cleaner in the gas vacuum tank 15 is crossed described pulse blast pipe 13 and is entered chamber 17 behind the described pulse valve, so offset partial pulse jetting deashing pressure.Because the pressure by air pressure in the described gas vacuum tank 15 is higher than the operating pressure of deduster, less than pulse jetting deashing pressure.Thereby the pulse jetting deashing pressure that makes described pulse valve diaphragm 20 suffered pressure be less than deduster deducts operating pressure poor of deduster.And, because use the constant pressure in the described gas vacuum tank 15 to offset partial pulse jetting deashing pressure, so described pulse valve diaphragm is not subjected to the influence of described pulse bag type dust collector operating pressure size variation.
In the above-described embodiments, described pulse valve diaphragm 20 quantity can be one, also can be for a plurality of.
In above-mentioned all embodiment, described pulse valve 10 can also be right-angle type, through type, submerged, right-angle type electromagnetic impulse valve, through type electromagnetic impulse valve or submerged electromagnetic impulse valve.
In sum, the utility model embodiment is provided with the gas vacuum tank with Compressed Gas, and the pulse blast pipe in the pulse valve is communicated with the gas vacuum tank.By this technical scheme, make pulse bag type dust collector when carrying out pulse jetting deashing, the pressure of the gas vacuum tank that is communicated with the pulse blast pipe and the pulse jetting deashing pressure in the deduster part of having cancelled out each other, the pressure that the pulse valve diaphragm is subjected to effectively reduces, thereby has alleviated pulse valve diaphragm compressive strength.The scheme of the utility model embodiment has not only effectively prolonged service life of pulse valve diaphragm, has also reduced the intensity of paired pulses valve itself and the requirement of manufacture craft, the cost of manufacture of having saved pulse valve.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
