Detailed description of the invention
As depicted in figs. 1 and 2, a kind of ash exhauster for negative-pressure operation deduster, comprise the taper flue-dust retainer 1 be arranged on bottom deduster, the sidewall of taper flue-dust retainer 1 offers ash discharging hole 2, described ash discharging hole 2 place is provided with a hermatic door, sealing door is made up of rubber gasket 3 and the support frame 4 be arranged on rubber gasket 3, support frame 4 can adopt net metal gratings, it is in order to increase the rigidity of hermatic door, prevent rubber gasket 3 pliable-closure that collapses not tight, a horizontally disposed bearing pin 5 is installed with above ash discharging hole 2, bearing pin 5 is equipped with multiple back-moving spring 6, one end of back-moving spring 6 is connected with support frame 4 upper end of hermatic door, the other end supports or is connected on the sidewall of taper flue-dust retainer 1, described hermatic door is close on ash discharging hole 2 under the suction function of deduster dust removal operation and the acting in conjunction of back-moving spring 6, so that ash discharging hole 2 is sealed, automatically open to carry out ash discharge under the deashing pressure effect that hermatic door operates at remover ash discharge dust.
Ash exhauster of the present invention is applied on the single pulse dust-collector of negative-pressure operation dedusting and pulse deashing, by Flange joint bottom deduster and between removing ash pipeline.As shown in Figure 1, this deduster comprises a deduster body 13, air inlet 10 is provided with in the bottom of deduster body 13, top is provided with gas outlet 11, what carry dust treats that dedusting gas enters in deduster body 13 from air inlet 10, after depression dust-removing, discharge clean gas from gas outlet 11 by blower fan.In dust removal process, be in negative pressure state in deduster body, negative pressure is generally 60 ~ 80% of blower pressure, and under the reset response of this suction function and back-moving spring 6, both actings in conjunction make hermatic door close, and are sealed up by ash discharging hole 2.During deduster deashing, the deashing gas bag 12 that deduster body 13 top is arranged abrupt release can reach 4 ~ 6 atmospheric deashing pressure, hermatic door is opened to carry out ash discharge automatically at this pressure, when pulse dust cleaning pressure is excessive, can carry out the impact that compensation sealing door has little time reset by back-moving spring 6.When dedusting again, hermatic door is automatically closed under the double action of dedusting negative pressure and back-moving spring, and flue-dust retainer continues dust stratification, waits for that the next ash discharge cycle carries out deashing.
As shown in Figure 3 and Figure 4, bearing pin 5 is installed on the sidewall of taper flue-dust retainer 1, and be positioned at the top of ash discharging hole 2, multiple back-moving spring 6 is disposed on bearing pin 5, bearing pin 5 is provided with multiple baffle plate, baffle plate is positioned at the end of back-moving spring 6 to play barrier effect to back-moving spring 6, prevents back-moving spring 6 from moving on bearing pin 5.Two back-moving springs 6, one being positioned at bearing pin 5 two ends lean on the end cap of bearing pin 5 self to stop that it comes off from bearing pin 5, and another fixing back-up ring 14 arranged by bearing pin 5 end stops that it comes off, and fixing back-up ring 14 is stuck on bearing pin 5 by split pin 15.
As shown in Figure 2, the cross section of described taper flue-dust retainer 1 is quadrangle, the sidewall of the pair of opposing of taper flue-dust retainer 1 is equipped with the ash discharging hole 2 of a rectangle, ash discharging hole 2 is preferably arranged near the bottom of taper flue-dust retainer 1 sidewall, the shape of ash discharging hole 2 is not limited to rectangle, also can be poroid or other structures.An ash discharge platform 7 is provided with in the bottom of taper flue-dust retainer 1, the side that ash discharge platform 7 is relative with two ash discharging holes 2 is equipped with an inclined-plane 8, two inclined-planes 8 intersect formation fin on the top of ash discharge platform 7, the bottom on two inclined-planes 8 connects to the edge, lower end of the ash discharging hole 2 of respective corresponding side.The setting of ash discharge platform 7 enables the dust be gathered in bottom taper flue-dust retainer 1 discharge from ash discharging hole 2 fast, easily, and ash discharge thoroughly, can not in taper flue-dust retainer 1 remaining dust.
As shown in Figure 5 and Figure 6, the periphery of the side of the relative ash discharging hole 2 of described rubber gasket 3 is provided with a circle abrasion sealer 9, and abrasion sealer 9 is close on the edge of ash discharging hole 2 periphery when hermatic door is in closed condition.The setting of abrasion sealer 9 can increase the laminating degree of hermatic door and ash discharging hole 2, improves the sealing effectiveness of hermatic door further.
