Description
Technical field
The invention belongs to biomass layer burner technical fields, and in particular to a kind of to be used for what biomass layer burner face arch leaked out
Sealing device.
Background technology
Biomass layer burner is a kind of main Types of biomass boiler, and biomass fuel is on traveling-grate stoker by preheating
Dry, pyrolysis devolatilization analyzes burning, fixed carbon burning and after-flame three phases.Biomass layer burner is due to traveling-grate stoker at present
The needs of installation, there are larger spare spaces at face arch position so that and combustion space poor sealing causes high-temperature flue gas to waste,
Flue gas can also benefit leak out by housing seal.Since fire grate rotates when biomass layer burner is burnt, burner hearth environment is long
Phase is under the mal-condition of high temperature, high vibration, high dust, and burner hearth internal part service life receives larger impact, therefore solves
Certainly face arch sealing problem is very difficult.
The content of the invention
The technical problem to be solved by the present invention is to：A kind of sealing device to leak out for biomass layer burner face arch is provided,
To solve above-mentioned problems of the prior art.
The technical solution that the present invention takes is：A kind of sealing device to leak out for biomass layer burner face arch, including chain
Fire grate feeds one end in traveling-grate stoker and sets heat safe elastic sealing strip, elastic sealing strip contact traveling-grate stoker surface and
It keeps contacting with side before and after burner hearth.
Preferably, above-mentioned elastic sealing strip slant setting.
Preferably, stiffening piece is provided on the upside of above-mentioned elastic sealing strip and forms V-structure with elastic sealing strip upper end.
Preferably, above-mentioned elastic sealing strip is fixedly connected on hearth housing by screw.
Preferably, above-mentioned elastic sealing strip lower end sets heat resistant and wear resistant piece, is set at heat resistant and wear resistant piece contact fire grate
Arc fold bending structure reduces cost of manufacture, improves leakproofness and wearability.
Beneficial effects of the present invention：Compared with prior art, effect of the invention is as follows：
（1）The present invention can play the high-temperature flue gas of generation certain barrier effect in fire grate end set elastic sealing strip,
High-temperature flue gas can not further be spread, and be deposited in burner hearth and carried out heat exchange, reduced the waste of high-temperature flue gas, improved burner hearth
The thermal efficiency, the present invention have the characteristics that simple in structure, easy for installation, manufacture is at low cost；
（2）The elastic sealing strip of the present invention can bear strenuous vibration when fire grate rotates；
（3）The heat safe elastic sealing strip of the present invention adapts to the adverse circumstances of the high dust of thermal expansion；
（4）Elastic sealing strip is made of wear-resistant material, and the position that wear-resisting elastic sealing strip is contacted with stoker surface is wear-resisting
Property is good, and service life is long.
Description of the drawings
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is A portions enlarged structure schematic diagram in Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings and the present invention is described further in specific embodiment.
Embodiment 1：As Figure 1-Figure 2, a kind of sealing device to leak out for biomass layer burner face arch, including chain
Fire grate 4 feeds one end in traveling-grate stoker 4 and sets heat safe elastic sealing strip 3, and elastic sealing strip 3 contacts 4 surface of traveling-grate stoker
And it keeps contacting with side before and after burner hearth.
Preferably, above-mentioned 3 slant setting of elastic sealing strip, lower end are pressed against on fire grate, increase sealing blocking effect.
Preferably, above-mentioned 3 upside of elastic sealing strip is provided with stiffening piece 5 and forms V-type knot with 3 upper end of elastic sealing strip
Structure improves the rigidity of elastic sealing strip, it is further provided sealing blocking effect.
Preferably, above-mentioned elastic sealing strip 3 is fixedly connected on hearth housing 6 by screw or welding manner, is convenient to mount and dismount.
Preferably, above-mentioned 3 lower end of elastic sealing strip sets heat resistant and wear resistant piece 7, and heat resistant and wear resistant piece 7 contacts to be set at fire grate
Arc fold bending structure is put, elastic sealing strip 3 using welding or is bolted to connection with heat resistant and wear resistant piece 7.
Biomass fuel is sent into burner hearth by feeding system 2, falls the tiering on traveling-grate stoker 4, raw as fire grate rotates
Biomass fuel layer is slowly sent into fire box's burning, and the high-temperature flue gas generated is spread forwards, backwards, and a part is by before burner hearth
Arch 1 blocks, and a part diffuses to fire grate forepart, is blocked and can not further spread by elastic sealing strip 3, is deposited in burner hearth, into
Row heat exchange.Elastic sealing strip 3 is made of flexible heat-resisting material, such as heat safe spring steel, installs elastic sealing strip welding additional
In case inside, with stoker surface flexible contact, contact site installs wear plate, while ensure that sealing effect, Ke Yicheng additional
By high temperature, high vibration, high smoke and dust environment, reduce the waste of high-temperature flue gas, improve the burner hearth thermal efficiency.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can readily occur in change or replacement, should all contain
Within protection scope of the present invention, therefore, protection scope of the present invention should be based on the protection scope of the described claims lid.
