Ash-transmission system, it is positioned at lower stationary pipes bottom, and opening part is provided with ash-transmission system flange, and this ash-transmission system flange is connected with the lower adpting flange of described lower stationary pipes.
Further, described lower stationary pipes upper port is arranged with extrusion orchid outward, and this extruding flange consists of upper and lower two-layer flange, between two-layer flange, with extruding bolt, is connected and fixed.
Further, in the inner side of described extruding flange lower floor flange, be provided with oblique groove.
Further, in described oblique groove and the gap that extruding flange upper strata flange forms, be provided with sealing gasket.
Further, the deformation quantity that the length of fixed pipe and lower stationary pipes overlapping part is produced by the actual thermal expansion of ash bucket determines.
Further, described sealing gasket is made by soft rubber material.
The beneficial effects of the utility model are:
The utility model arranges elastic connecting device between sack cleaner ash bucket and ash-transmission system, this device consists of upper and lower stationary pipes, upper stationary pipes can be free to slide in lower stationary pipes, when ash bucket generation thermal expansion, this device can elimination effect stress up and down thereon, avoids ash bucket ash hole and ash-transmission system to be directly firmly connected the ash bucket steel plate cracking that may cause.The design of the utility model device is ingenious, simple in structure, with low cost, and to dust collector ash hopper, great role is played in normal work at high temperature.
Accompanying drawing explanation
Fig. 1 is the utility model elastic connecting device section right side structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, to make those skilled in the art can implement according to this with reference to description word.
Refer to Fig. 1, a kind of elastic connecting device being arranged between sack cleaner ash bucket and ash-transmission system, comprising:
Ash bucket (1), it is the narrow inverted cone-shaped structure of the wide lower ending opening of upper end open, at the outer ash bucket flange (11) that is arranged with of its lower ending opening;
Upper stationary pipes (2), it is positioned at ash bucket (1) bottom, is the cylindrical structural of hollow, and port periphery is provided with adpting flange (21) thereon, and described upper adpting flange (21) is connected with ash bucket flange (11);
Lower stationary pipes (3), its cylindrical structural that is hollow, is sheathed on fixed pipe (2) lower end, is slidably connected with upper stationary pipes (2), and its lower port is arranged with lower adpting flange (31) outward;
Ash-transmission system (4), it is positioned at lower stationary pipes (3) bottom, and opening part is provided with ash-transmission system flange (41), and this ash-transmission system flange (41) is connected with the lower adpting flange (31) of described lower stationary pipes (3).
In described lower stationary pipes (3) upper port, be arranged with extrusion orchid (5) outward, this extruding flange (5) consists of upper and lower two-layer flange, between two-layer flange, with extruding bolt (6), is connected and fixed.
Inner side at described extruding flange (5) lower floor flange is provided with oblique groove (8).
In described oblique groove (8) and the gap that extruding flange (5) upper strata flange forms, be provided with sealing gasket (7).Described sealing gasket (7) is made by soft rubber material.
In the present embodiment, the deformation quantity that the length of fixed pipe (2) and lower stationary pipes (3) overlapping part is produced by the actual thermal expansion of ash bucket (1) determines, calculates this swell increment and is designed to 50mm.
In sack cleaner, ash bucket (1) is fixedly mounted on below filter bag, and ash-transmission system (4) is connected to ash bucket (1) bottom, and both are all fixed, can not be subjected to displacement.Now, if ash bucket (1) is because of the generation deformation of being heated, the ash-transmission system (4) that is firmly connected in ash bucket (1) bottom will be subject to the downward active force of ash bucket (1), this active force discharges nowhere, only can act on ash bucket (1) and ash-transmission system (4), therefore,, when active force is larger, can makes the steel plate of ash bucket (1) bottom strut and split.
The utility model arranges elastic connecting device between ash bucket (1) and ash-transmission system (4), when ash bucket (1) thermal expansion, effect of stress is in this elastic connecting device, the relative sliding of stationary pipes up and down in device, can eliminate stress, avoid it to react on ash bucket (1) or ash-transmission system (4).In addition, the utility model arranges sealing gasket (7) on top, upper and lower stationary pipes gap, plays excellent sealing effect, avoids the interior dust of ash bucket (1) to leak in air by gap, causes secondary pollution.
Above-mentioned embodiment is only to functional descriptions of the present utility model; not design of the present utility model and scope are limited; do not departing under the prerequisite of the utility model design philosophy; various distortion and improvement that those skilled in the art make the technical solution of the utility model, within all dropping on protection domain of the present utility model.
