Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of bag hose blowback system of the present utility model.
Detailed description of the invention
Refer to Fig. 1, inventor of the present utility model, in order to understand the technical solution of the utility model better, below by embodiment particularly, and is described in detail by reference to the accompanying drawings:
Refer to Fig. 1, a kind of bag hose blowback system of the present utility model comprises winding-up steel pipe 10, impulse electromagnetic valve 2, first thin type ball valve 41, second thin type ball valve 42, gas collection bag 7.Wherein gas collection bag 7 is fixed on the outer wall of bag hose 8, and the compressed air in gas collection bag 7, through the first thin type ball valve 41, impulse electromagnetic valve 2 and the second thin type ball valve 42, sprays in bag hose by winding-up steel pipe 10, reaches the object of cleaning cloth bag dust.
The air inlet of impulse electromagnetic valve 2 is communicated with the first thin type ball valve 41 by the first steel pipe 11, and the exhaust outlet of impulse electromagnetic valve 2 is communicated with the second thin type ball valve 42 by the second steel pipe 12.Because the air inlet of impulse electromagnetic valve 2 and exhaust outlet are all provided with screw thread, the connection therefore between the air inlet of impulse electromagnetic valve 2 and the first steel pipe 11, the connection between exhaust outlet with the second steel pipe 12 is and is threaded.
One end that first steel pipe 11 is communicated with the first thin type ball valve 41 is provided with the first lap joint flange 31, and the first steel pipe 11 and the first thin type ball valve 41 are fixed.One end that second steel pipe 12 is communicated with the second thin type ball valve 42 is provided with the second lap joint flange 32, and the second steel pipe 12 and the second thin type ball valve 42 are fixed.First steel pipe 11 and the second steel pipe 12 can according to impulse electromagnetic valve 2 engage situation, the installation position of corresponding adjustment the first lap joint flange 31 and the second lap joint flange 32, impulse electromagnetic valve 2 is avoided to have mount stress, so that damage impulse electromagnetic valve 2, thus extend the service life of impulse electromagnetic valve 2.
Under normal operating conditions, first thin type ball valve 41 and the second thin type ball valve 42 are in normally open, when impulse electromagnetic valve 2 needs to change or keep in repair, the first thin type ball valve 41 can be closed and the second thin type ball valve 42 is changed online or overhauls, and not affecting the normal work of the impulse electromagnetic valve 2 in other bag hose blowback system, the hazardous gas that simultaneously also avoid in bag hose leaks outside the injury caused operative employee.
Be communicated with by air inlet steel pipe 13 between gas collection bag 7 with the first thin type ball valve 41, the connected mode between air inlet steel pipe 13 with gas collection bag 7 is for being threaded.One end that air inlet steel pipe 13 is communicated with the first thin type ball valve 41 is provided with air inlet lap joint flange 33, and air inlet steel pipe 13 and the first thin type ball valve 41 are fixed.Air inlet steel pipe 13 can according to gas collection bag 7 engage situation, the installation position of corresponding adjustment air inlet lap joint flange 33, avoids gas collection bag 7 to have mount stress, so that damages gas collection bag 7.
Fixed by screw bolt and nut between air inlet lap joint flange 33, first thin type ball valve 41 and the first lap joint flange 31.
Second thin type ball valve 42 is communicated with by steel pipe 10 of jetting with bag hose 8, and one end that winding-up steel pipe 10 is communicated with the second thin type ball valve 42 is provided with lap joint flange 34 of jetting, and winding-up steel pipe 13 and the second thin type ball valve 42 are fixed.Fixed by screw bolt and nut between winding-up lap joint flange 34, second thin type ball valve 42 and the second lap joint flange 32.
First thin type ball valve 41 and the second thin type ball valve 42 all can manual-locks.
Corresponding installation the first thin type ball valve 41 and the second thin type ball valve 42 before and after impulse electromagnetic valve 2, corresponding connected set gas bag 7 and bag hose 8, like this when changing impulse electromagnetic valve 2, just can turn off the first thin type ball valve 41 and the second thin type ball valve 42 be communicated with it, change online, and do not affect the normal work of the impulse electromagnetic valve 2 in other bag hose blowback system.About 10 minutes total times are dismantled and installed to an impulse electromagnetic valve 2 on old bag hose blowback system 8, in a kind of bag hose blowback system of the present utility model, change an impulse electromagnetic valve 2 need two minutes, by a set of bag hose 8 there being 120 cover bag hose blowback systems calculate, the set-up time of 16 hours can be saved.Greatly shorten the operating time of operating personnel, reduce labour intensity, under effectively solving online operating mode, the difficult problem that impulse electromagnetic valve 2 overhauls and changes, it also avoid and need bag hose entirety to stop and the production loss that causes.
Connection between impulse electromagnetic valve 2 and bag hose 8 adopts steel pipe Hard link, replaces old rubber hose, avoids the work needing to change rubber hose because rubber tube is aging.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
