Abstract
The invention provides a flexible sealing device of a fire grate push rod of a refuse incineration boiler, which guarantees the reliable seal between the fire grate push rod and a front wall board of fire grate, avoids attrition and ensures operation safety and economical efficiency of the boiler. The flexible sealing device comprises the fire grate push rod, the front wall board of fire grate and an air chamber, wherein a push rod mounting hole is arranged on the front wall board of fire grate, and the middle part of the fire grate push rod passes through the push rod mounting hole and is stretched into the air chamber. The flexible sealing device is characterized in that a protective sleeve is sleeved on the middle part of the fire grate push rod, a circular ring is welded on the end away from the air chamber of the protective sleeve, the fire grate push rod is welded on the inner ring surface of the circular ring, a flange is sleeved on the protective sleeve, the flange is situated on the outer side of the air chamber, the front wall board of fire grate is welded on the circular ring end of the flange, a flexible wavy expansion joint is sleeved on the outer peripheral surface of the protective sleeve, and the flexible wavy expansion joint is located between the circular ring and the flange.
Description
Technical field
The present invention relates to the modular construction technical field of boiler, be specially the flexible seal device of the fire grate push rod of garbage burning boiler.
Background technology
Domestic waste, be a kind of regenerative resource, utilizes waste incineration and generating electricity, has the energy of saving and land resource, antipollution social benefit, also has good economic benefit.The grate of refuse incineration boiler major part all adopts reciprocating fire grate at present.Reciprocating fire grate is driven by hydraulic transmission, and hydraulic transmission promotes fire grate realization reciprocating motion by fire grate push rod.The contacting mechanical seal structure adopted when fire grate push rod passes fire grate front panel reciprocating motion due to fire grate push rod after operation a period of time increases the rear fire grate push rod of hermetically-sealed construction wearing and tearing and fire grate front panel gap, under the effect of grate wind chamber blast, make outside the interior high temperature air of grate wind chamber and dust ejection stove, both dangerous, the economical operation that also has influence on boiler.
Summary of the invention
For the problems referred to above, the invention provides the flexible seal device of the fire grate push rod of garbage burning boiler, it guarantees to arrange the positiver sealing between push rod and fire grate front panel, and has avoided wearing and tearing, has guaranteed security, the economy of boiler operatiopn.
The flexible seal device of the fire grate push rod of garbage burning boiler, its technical scheme is such: it comprises fire grate push rod, the fire grate front panel, air compartment, be provided with the push rod installing hole on described fire grate front panel, described air compartment is goed deep into after running through described push rod installing hole in the middle part of described fire grate push rod, it is characterized in that: the middle part of described fire grate push rod is set with protective casing, described protective casing be welded to connect annulus away from described air compartment end, the inner ring surface of described annulus is welded to connect described fire grate push rod, flange is placed in described protective casing, described flange is positioned at the described air compartment outside, the annulus end of described flange is welded to connect described fire grate front panel, flexible corrugated-type expansion joint is placed in the outer edge surface of described protective casing, described flexible corrugated-type expansion joint is positioned at described annulus, between flange, the two ends of described flexible corrugated-type expansion joint are fastenedly connected respectively the anchor ring of described annulus, the end face of flange of flange.
It is further characterized in that: described flexible corrugated-type expansion joint is that to be that heat-resistance and flame-retardant fiber cloth is compound form for heat resistant rubber, internal layer by skin;
The two ends of described flexible corrugated-type expansion joint connect the anchor ring of described annulus, the end face of flange of flange by bolt, fastening nuts respectively, between described nut and described flexible corrugated-type expansion joint, packing ring are housed.
After adopting structure of the present invention; when fire grate push rod moves back and forth, annulus and protective casing synchronizing moving, flexible corrugated-type expansion joint of while are also thereupon flexible; this flexible seal device assembly had both been realized reliable sealing function between fire grate push rod and fire grate front panel; and avoided wearing and tearing, guaranteed security, the economy of boiler operatiopn.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
See Fig. 1, it comprises fire grate push rod 1, fire grate front panel 2, air compartment 3, be provided with push rod installing hole 4 on fire grate front panel 2, air compartment 3 is goed deep into after running through push rod installing hole 4 in the middle part of fire grate push rod 1, the middle part of fire grate push rod 1 is set with protective casing 5, protective casing 5 be welded to connect annulus 6 away from air compartment 3 ends, the inner ring surface of annulus 6 is welded to connect fire grate push rod 1, flange 7 is placed in protective casing 5, flange 7 is positioned at air compartment 3 outsides, the annulus end of flange 7 is welded to connect fire grate front panel 2, flexible corrugated-type expansion joint 8 is placed in the outer edge surface of protective casing 5, flexible corrugated-type expansion joint 8 is positioned at annulus 6, between flange 7, the two ends of flexible corrugated-type expansion joint 8 are respectively by bolt 9, nut 10 is fastenedly connected the anchor ring of annulus 6, the end face of flange of flange 7, between nut 10 and flexible corrugated-type expansion joint 8, packing ring 11 is housed, flexible corrugated-type expansion joint 8 is heat resistant rubber by skin, internal layer is the compound composition of heat-resistance and flame-retardant fiber cloth.
