Abstract
The utility model relates to a kind of sealing device for roller, it comprises seal ring hoop, extension spring device and spring pressuring plate, described seal ring hoop can fixing two semicircular ring of screw be made up of two ends, described extension spring device is arranged on the semicircular ring joint of described seal ring hoop, described spring pressuring plate is fixedly mounted on described seal ring hoop, reach further sealing effect, also be not worn the impact brought, seal ring is made to be close to body of heater well all the time, ensure high leak tightness, reduce heat energy loss, micro-vacuum state is adopted in stove, effectively prevent flue gas, furnace gas after burning and dust also can not leak to outside.
Description
Technical field
The utility model relates to incineration device field, particularly relates to the seal arrangement field for incinerator cylinder.
Background technique
Along with the acceleration of urbanization process, the rubbish quantity produced and discharge increases rapidly, but along with many landfill yards reach capacity, masses are also concerned about further to the environmental problem caused by incorrect waste disposal mode, the selection rubbish that burning has become an attractive process refuse burns energy minimizing, save land used, also can eliminate various pathogen.
Prior art burns the mode that incinerator cylinder seal ring used adopts directly laminating, and after causing long term wear, sealability declines, and heat energy loss is serious, pollutes surrounding enviroment.
Model utility content
The purpose of this utility model is to provide a kind of sealing device for roller of rational in infrastructure, good seal performance, and embodiment of the present utility model adopts following technological scheme:
A kind of sealing device for roller, it comprises seal ring hoop, extension spring device and spring pressuring plate, and described seal ring hoop is formed by described extension spring device docking by two semicircular ring, and described spring pressuring plate is fixedly mounted on described seal ring hoop.
Further, described extension spring device comprises hexagon head bolt, extension spring and nut, described hexagon head bolt is arranged on one end of a semicircular ring, what described nut was arranged on another semicircular ring connects one end corresponding thereto, described extension spring one end is connected on hexagon head bolt, described extension spring the other end attaching nut, thus two semicircular ring are coupled together formed described seal ring hoop.
Further, described seal ring hoop and extension spring device form the annulus of a sealing.
Further, described spring pressuring plate is multiple, and is uniformly distributed in seal ring hoop circumferentially.
Further, the semicircular ring joining place of described seal ring hoop respectively installs two extension spring devices.
In sum, the beneficial effects of the utility model: sealing device for roller takes more reasonably spring pressuring plate structure, seal ring is made to be close to body of heater well all the time after meeting long-term running, ensure high leak tightness, reduce heat energy loss, adopt micro-vacuum state in stove, effectively prevent flue gas, the furnace gas after burning and dust also can not leak to outside.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of sealing device for roller of the present utility model;
Fig. 2 is the structural representation of extension spring device of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1-2, it illustrates the concrete structure of sealing device for roller of the present utility model, described sealing device for roller, it comprises seal ring hoop 1, extension spring device 3 and spring pressuring plate 2, seal ring hoop 1 is connected to form by extension spring device 3 by two semicircular ring, the seal ring of incinerator and incinerator cylinder surface held tightly by seal ring hoop 1, extension spring device 3 is arranged on the semicircular ring joint of seal ring hoop 1, spring pressuring plate 2 is fixedly mounted on seal ring hoop 1, extension spring device 3 makes seal ring be close to body of heater all the time in the weight range of extension spring, reaches good sealing effect.
Wherein extension spring device 3 comprises hexagon head bolt 301, extension spring 302 and nut 303, hexagon head bolt 301 is arranged on one end place of seal ring hoop 1 one semicircular ring, one end place that another semicircular ring that nut 303 is arranged on described seal ring hoop 1 connects corresponding thereto, extension spring 302 one end is connected on hexagon head bolt 301, extension spring 302 the other end is connected to nut 303 place, incinerator cylinder and seal ring long-play can wear and tear, and extension spring device 3 is just in the weight range of extension spring 302, seal ring can be made to be close to body of heater, ensure high leak tightness, reduce heat energy loss.
Seal ring hoop 1 of the present utility model and extension spring device 3 form the annulus of a sealing, and energy and incinerator are shown consideration for and closed like this, reduce heat energy loss.
Spring pressuring plate of the present utility model has multiple, and is uniformly distributed in seal ring hoop 1 circumferentially, and each local of incinerator seal ring 1 can be allowed to be close to body of heater.The semicircular ring joining place of seal ring hoop 1 respectively installs 2 extension spring devices 3, makes the stress balance of seal ring hoop 1.
Sealing device for roller of the present utility model, is not limited to the structure in above-described embodiment, can carry out multiple modification, in a word, all falls in scope of the present utility model not departing from all improvement in the utility model scope.
Claims (5)
1. a sealing device for roller, is characterized in that, it comprises seal ring hoop, extension spring device and spring pressuring plate, and described seal ring hoop is formed by described extension spring device docking by two semicircular ring, and described spring pressuring plate is fixedly mounted on described seal ring hoop.
