Technical field
The present invention relates to apparatus fields of baking bricks, and in particular to a kind of high tenacity colliery wastes brick sintering of the pre- heat recovery function of band
Equipment.
Background technique
The high tenacity colliery wastes brick agglomerating plant of the existing pre- heat recovery function of band is all that multiple kilns are passed through pipeline string
Connection gets up, and then directly blasts in first kiln hot-air by pipeline and is sintered to the adobe in first kiln,
Then hot-air enters in second kiln through pipeline and preheats to the adobe in second kiln, later, second kiln
Interior hot-air enters in third kiln through pipeline preheats the adobe in third kiln, and such hot-air is past always
Conveying, achievees the purpose that make full use of the thermal energy in hot-air in next kiln.Although this kind of agglomerating plant good energy saving property,
Be its there are still some problems in actual use；
Such as sintering when hot-air enter after kiln do not stop substantially just enter pipeline leave the kiln, although hot-air is straight
It connects and is contacted with adobe, but since hot-air flow velocity is fast, time of contact is short, therefore actually needs to consume more heat ability
By adobe sinter molding, therefore traditional agglomerating plant coal consumption or air consumption is generally higher；
In addition, adobe is entered in next kiln by the moisture of thermal evaporation with hot-air, and so, kiln more rearward
Interior moisture is heavier, and pre-heat effect is also poorer, therefore more kilns is theoretically arranged can more fully absorb heat, but real
Humidity on border in the backward in hot-air is bigger, is unfavorable for the preheating of adobe instead.

Pad is equipped with gasket 7 between sealing cover and furnace body 5, and gasket 7 is used to enhance the sealing between sealing cover and furnace body 5
Property.
Jack 16 is provided on the side wall of support baseboard 13, jack 16 facilitates fork truck to insert support baseboard 13.
One end of appendix 2 is connected to the escape pipe 20 of a upper kiln 1, the other end of appendix 2 and next kiln 1
Air inlet pipe 21 be connected to, the hot gas that escape pipe 20 is discharged in a upper kiln 1 flows through appendix 2 and enters in next kiln 1
In big coiled pipe 18.
Relief valve 26 is installed, the threshold value of relief valve 26 is greater than the threshold value of pressure maintaining valve 25, when in furnace body 5 on 5 outside of furnace body
Air pressure be more than relief valve 26 threshold value when, relief valve 26 open, reduce furnace body 5 in air pressure, in this way design, once pressure maintaining valve
When 25 damage, relief valve 26 can also be worked normally, to guarantee that air pressure is unlikely excessively high in furnace body 5.
Furnace body 5 and sealing cover are all made of heat-barrier material production, design in this way, can reduce being generated by furnace body 5 and sealing cover
Thermal loss, further energy conservation and environmental protection.
The high tenacity colliery wastes brick agglomerating plant of the above-mentioned pre- heat recovery function of a kind of band, in use, first by high tenacity bastard coal
Stone brick adobe overlays on mounting table 12, forms adobe pile 31, is then placed on lifting seat plate 14 with equipment such as fork trucks,
Later, starting Electrohydraulic push rod 15 drives support baseboard 13 to rise, until mounting table 12 is inserted into input and output material hole 11 and seals therewith
Then connection opens gas valve 23 and air valve 24, lights burner 22 and start air blower 4, fired burner 22 by air blower 4
It burns the heat generated to be blown into big coiled pipe 18 by air inlet pipe 21, later, hot-air enters in small coiled pipe 19 and along small snake
Coil pipe 19 enters in escape pipe 20, finally enters in appendix 2 from 20 upper end of escape pipe, is then entered by appendix 2 next
In the air inlet pipe 21 of kiln 1, last thermal current is injected into the absorbing liquid contained in tail gas absorption box 3, and absorbing liquid is for inhaling
The polluted gas such as nitrogen oxides, sulfide in ending gas, since hot-air passes through big coiled pipe 18, small coiled pipe 19 and outlet
Kiln 1 is just left after pipe 20, therefore residence time of the hot-air in kiln 1 is longer, compared to traditional hot-air directly under
The sintering processing for going to next kiln 1 is out on and after kiln 1, kiln 1 of the invention can significantly extend hot gas
Flow flowing time in kiln 1, to make the abundant heating kiln 1 of hot-air, to greatest extent using hot-air to adobe into
Row sintering or preheating, significantly reduce energy consumption, and practicability is good, pass through big coiled pipe 18, small coiled pipe 19 and escape pipe in hot-air
During 20, big coiled pipe 18, small coiled pipe 19 and the outside radiations heat energy of the meeting of escape pipe 20, Heating guard cylinder 17 are then prevented
Casing 17 heats adobe pile 31, so that the sintering of adobe pile 31 is completed, the damp and hot sky generated in 31 sintering process of adobe pile
Gas enters from bottom to top in festoon drier 28, and the drying hot-air after festoon drier 28 is dry enters in annular groove 27 simultaneously
It is discharged into furnace body 5 by gas vent 29, as big coiled pipe 18, small coiled pipe 19 and escape pipe 20 constantly conduct heat outward, in furnace body 5
Air pressure and temperature it is higher and higher, when temperature be more than pressure maintaining valve 25 threshold value when, pressure maintaining valve 25 open, high-pressure hot air warp
Pressure maintaining valve 25 enters in escape pipe 20 and enters in appendix 2 with the hot-air in escape pipe 20, due in sealing cover
Add festoon drier 28, thus can ensure be sent into escape pipe 20 in hot-air be it is dry, efficiently solve preheating
The larger problem of humidity in air, pre-heat effect are good.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is 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.
