Abstract
The utility model relates to a coal and slag combustion device for a boiler, comprising a front boiler arch, a back boiler arch, a back wall, a hearth, a boiler drum, a chain grate and a front coal bucket. The utility model also comprises a slag bucket which is installed at the outer side of the back wall, a slag conveying device of which one end is installed above the slag bucket, a slag-pushing piston device placed at the outer side of the lower part of the slag bucket, and two side walls which are respectively arranged at both ends of the back boiler arch. The two side walls form a box-shaped channel which the slag can be conveyed and baked in. The utility model can combust the coal and the slag, and has the advantages that the fuel cost is saved and the environmental sanitation is protected.
Description
The utility model relates to chain-grate industrial boiler, can burning coal in particularly a kind of boiler again can combustion residue device.
Existing Industrial Boiler generally can only burning coal, and can not combustion residue, and fuel is single.
The purpose of this utility model provides a kind of boiler coal, waste residue and holds concurrently and burn device, it can burning coal again can combustion residue, saved fuel cost, the protection environmental sanitation.
A kind of boiler coal described in the utility model, the double device that burns of waste residue comprise preceding chimney arch, back chimney arch, Hou Qiang, burner hearth, drum, traveling-grate stoker and preceding coal bunker, it comprises that also one is installed in the waste residue bucket in the wall outside, back, one wherein an end be installed in the waste residue conveying device of waste residue bucket top, one be positioned at the waste residue bucket bottom outside push away the slag piston apparatus, and two abutment walls that two sides are provided with respectively on the chimney arch of back, above-mentioned dual side-edge wall forms the box-shaped passage that a waste residue is carried therein and dried.
The existing boiler plant of the utility model utilization also can be burnt waste residue in burning coal, and does not need to acquire in addition incinerator.For the waste residue that contains higher moisture content such as the dregs of a decoction, rubbish, the utility model all can burn, and has saved fuel cost, the protection environmental sanitation.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the double structural representation that burns device of a kind of boiler coal, waste residue.
Fig. 2 is the A-A cutaway view among Fig. 1.
Fig. 3 is the B-B cutaway view among Fig. 1.
Referring to Fig. 1 to Fig. 3, a kind of boiler coal, the double device that burns of waste residue comprise preceding chimney arch 1, back chimney arch 2, back wall 3, burner hearth 4, drum 5, traveling-grate stoker 6 and preceding coal bunker 7.
It also comprise a waste residue bucket 8, that is installed in wall 3 outsides, back wherein the end waste residue conveying device 9, that is installed in waste residue bucket 8 tops be positioned at the outside, waste residue bucket 8 bottoms push away slag piston apparatus 10 and two abutment walls 11 that two sides are provided with respectively on the chimney arch 2 of back.Abutment wall 11 on the back chimney arch 2 forms a box-shaped passage 12, and waste residue is carried in box-shaped passage 12 and passed through, and dries simultaneously.
Push away slag piston apparatus 10 and comprise the wherein push rod 14 that is connected with power set 13 of an end of power set 13,, and a piston 15 that is connected with push rod 14 other ends.Motor and gearbox are housed in the power set 13, and push rod 14 connects an end of power set 13 and is connected with the eccentric point of gearbox push-rod wheel 16 wherein, make rotatablely moving of push-rod wheel 16 become the reciprocating motion of push rod 14, and then promotion piston 15 pushes away slag.
Back chimney arch 2 is formed by cast iron casting.Front end two avris of back chimney arch 2 are respectively equipped with waste residue and shunt outlet 17, and when waste residue exported 17 by the 12 arrival waste residues shuntings of box-shaped passage, waste residue just dropped on the traveling-grate stoker 6, arrives the coal that is burning in the burner hearths 4 with coal bunker before entering 7 and burns.
Claims (3)
1. a boiler coal, waste residue are held concurrently and are burnt device, it comprises preceding chimney arch, back chimney arch, Hou Qiang, burner hearth, drum, traveling-grate stoker and preceding coal bunker, it is characterized in that, it comprises that also one is installed in the waste residue bucket in the wall outside, back, one wherein an end be installed in the waste residue conveying device of waste residue bucket top, one be positioned at the waste residue bucket bottom outside push away the slag piston apparatus, and two abutment walls that two sides are provided with respectively on the chimney arch of back, above-mentioned dual side-edge wall forms the box-shaped passage that a waste residue is carried therein and dried.
2. boiler coal according to claim 1, waste residue are held concurrently and are burnt device, it is characterized in that the described slag piston apparatus that pushes away comprises power set, the push rod that is connected with power set of an end wherein, and a piston that is connected with the push rod other end.
