Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structure cutaway view of the embodiment of the present invention;
In accompanying drawing: 1. magnetic valve; 2. gas storage bag; 3. elbow; 4. elasticity reset device; 5. Upstream section; 6. flange; 7. tract; 8. interior seal shaft; 81. sealing taperings; 82. bar portions; 9. ash bucket; 10. base; 11. fairleads.
The specific embodiment
Below by specific embodiment, the present invention is described in further detail.
As shown in Figure 1, a kind of for isolating the blowing device of the sack cleaner of corrosivity dust, this blowing device is installed on the ash bucket 9 of sack cleaner, ash bucket 9 is dust collectings of sack cleaner, when dust stockpiles in ash bucket 9, because dust is not necessarily dry, can be with certain moisture, long meeting of time one be hardened in ash bucket 9 so, so just need blowing device to blow pine to it, being convenient to derives from the outlet of bottom, this blowing device comprises breather pipe, interior seal shaft 8, valve and gas storage bag 2, described breather pipe be fixed on ash bucket 9 outsides and with ash bucket 9 internal communication, described breather pipe is that split type breather pipe comprises Upstream section 5 and tract 7, fixing by adpting flange 6 between described Upstream section 5 and tract 7, the downstream end of described tract 7 is threaded with base 10, the end, upstream of described Upstream section 5 elbow 3 that has been threaded, described elbow 3 is connected with valve.The outer wall of described base 10 welding and ash bucket 9; Like this, breather pipe is just fixed on ash bucket 9.Above-mentioned valve is preferably magnetic valve 1.
Described interior seal shaft 8 is slidably mounted in breather pipe, between described interior seal shaft 8 and breather pipe, be provided with elasticity reset device 4, described interior seal shaft 8 comprises bar portion 82 and sealing tapering 81, described bar portion 82 is slidably mounted on breather pipe by guider, the downstream end of described breather pipe is provided with inner conical surface, described inner conical surface coordinates with the sealing surface in sealing tapering 81, hermetically-sealed construction between interior seal shaft 8 and the downstream end of breather pipe can also be other structures in fact, for example, taper seat sealing, frustum sealing, trapezoidal sealing etc.Described guider comprises the fairlead 11 being arranged in breather pipe, this fairlead 11 by least two fixedly muscle be fixedly connected with breather pipe inwall, fixedly between muscle, there is the passage be convenient to Air Flow in each.The elastic force of this elasticity reset device 4 orders about the sealing surface of interior seal shaft 8 and the downstream end of breather pipe is sealed and matched, and described breather pipe is communicated with or is disconnected by described valve with gas storage bag 2.Described elasticity reset device 4 comprises a back-moving spring, in the bar portion 82 of described interior seal shaft 8, locating part is installed, described back-moving spring is pressed between locating part and fairlead 11 in advance, and described locating part is preferably nut, utilize nut can regulate the strain of back-moving spring, thereby guarantee optimal seal effect.
Because described interior seal shaft 8 is slidably mounted in breather pipe, between described interior seal shaft 8 and breather pipe, be provided with elasticity reset device 4, the elastic force of this elasticity reset device 4 orders about the sealing surface of interior seal shaft 8 and the downstream end of breather pipe is sealed and matched, described breather pipe is communicated with or is disconnected by described valve with gas storage bag 2, therefore, only interior seal shaft 8 need be made by resistant material, when winding-up, interior seal shaft 8 can be subject to the pressure that the gases at high pressure of high pressure breather pipe produce and compression reseting spring moves downstream, like this sealing surface with the separated object that reaches unlatching of inner conical surface of breather pipe downstream end, and when not jetting, because making interior seal shaft 8, the elastic force of back-moving spring resets, sealing surface with the inner conical surface fitted seal of breather pipe downstream end, guarantee that corrosivity dust does not enter breather pipe internal corrosion breather pipe and valve, guarantee the reliable and stable work of blowing device, increase the service life, reduce maintenance frequency and cost.
