The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of deduster off-line ash-clearing device in detail.
As figure Fig. 1-Fig. 5: the utility model comprises bracing frame 14, core tube 9, piston bush 12, pats and cover 10, return spring 13, rotate the wing 6, suspension rod 3, bearing 8, star nut 1.
Support frame as described above 14 is a three-legged support, is installed on the bag filter tubesheet 19 by bolt, over against the top in a card hole, whole off-line ash-clearing device is played the installation supporting role.
Described core tube 9, its center has a centre bore to connect this axle, descend therein the position to be drilled with a horizontal aperture 11 and communicate with centre bore, this axle has all been attacked external screw thread in two ends up and down, this core tube 9 is packed on the bracing frame 14 with locking nut and transition nuts 15 by its upper end screw thread.Be connected with magnetic valve 17 outlets by movable joint nut 16 in core tube 9 upper ends.
Described piston bush 12, it makes material is nylon or plastic cement, is fixed with the beating lid 10 that can seal the card hole with back-up ring on it; Piston bush 12 sealing shrouds are contained in the core tube 9, can slide up and down along core tube 9; Between piston bush 12 and core tube 9 return spring 13 is housed, is not having under the external force effect, return spring 13 can be all the time covers piston bush 12 10 and is promoted to high-order bit together with patting.
The described rotation wing 6 overlapped for 2 and 7 welded together compositions by two spray orifice pipes that match with described filter cylinder 20 internal diameter sizes 4 and metal (upper, and the rotation wing 6 is supported on the suspension rod 3 by the ball bearing 8 of its metal (upper cover by dual face seals; Described spray orifice pipe 4, be drilled with the more tiny spray orifice 5 of a row along its length direction, the included angle B of spray orifice axis and the rotation wing 6 central planes at 20 degree to 45 degree scopes, this not only made from its recoil strength of high velocity air of spray orifice 5 ejections can 6 rotations of driven rotary wing get up but also can make from the high velocity air of spray orifice 5 ejections can be stronger piping and druming on filter cylinder 20 inner surfaces.
Described suspension rod 3, its upper end has a screw, having two transverse holes at corresponding spray orifice tube inlet position communicates with its central blind hole, have a screw rod in its lower end, described suspension rod 3 passes the card hole and places the bag filter tubesheet below, screw by its upper end is connected with core tube 9, its central blind hole communicates with the core tube centre bore, and the centre bore that the screw rod by its lower end passes on filter cylinder 20 bottoms is pressed on filter cylinder 20 on the bag filter tubesheet 19 by star nut 1, thereby filter cylinder 20 is in place.
After the deashing instruction of receiving the deduster control module, magnetic valve 17 is opened, the deashing air-flow sprays in pressure gas bag 18, when flowing through core tube's 9 centre bores, act on the piston bush 12 via its horizontal aperture 11, piston bush 12 is covered 10 together with beating depress and be pressed on the bag filter tubesheet 19, seal the outlet of filter cylinder 20 inner chambers, make this filter cylinder 20 be in off-line state, no longer participate in the work of Chalk-dust filtering; The deashing air-flow continues to flow, flow in two spray orifice pipes 4 via suspension rod 3 transverse holes, spray to filter cylinder inner chamber filtrate inner surface at a high speed by its spray orifice 5 again, the rotation wing 6 rotates at a high speed under the recoil active force of the high velocity air of spray orifice 5 ejections, the rotation wing 6 limits rotate the limit at a high speed by its spray orifice 5 ejection high speed pressure air-flows, filter cylinder 20 chamber pressures evenly promote rapidly, and filter cylinder 20 is expanded, and the filtrate shake will stick to the dust of filter cylinder outer surface and shake off removing; Directly blow and beat on the filtrate inner surface by the high speed pressure air-flow of spray orifice 5 ejections simultaneously, the more tiny dust that sticks to the filtrate the inside is blown off, reached the effect of reverse reverse gas cleaning.Magnetic valve 17 cuts out, and the deashing air-flow stops, and piston bush 12 cover 10 get back to the extreme higher position under the effect of return spring 13 together with patting this moment, and the filter cylinder inner chamber exports and opens, and filter cylinder 20 is returned to the duty of Chalk-dust filtering again.
