Abstract
The utility model relates to a hedgehog type chain fire grate, comprising a coal hod, a tooth counting wheel, a drive chain ring, a fire grate segment, a sealing wind box, a housing, etc., which is characterized in that one end of the fire grate segment is cast with mounting holes, and a set of furnace gate pieces are fixed to both ends of drive chain ring by round steel, and the other end gears into the furnace gate pieces in the back row so that the upper surface of the fire grate forms a transmission plane, each row of furnace gate pieces which take fixed ends as shaft centers rolls over to form an upright form automatically, so that the slag can be sent to slag boxes. The utility model used in coal burning furnace overcomes the defects of easy-damage and inconvenient repair of the traditional fire grate, which is an ideal substitute of the traditional fire grate.
Description
The utility model relates to a kind of coal-fired furnace kiln random, specifically a kind of novel chain fire grate.
The traveling-grate stoker of present industrial use has: continuous band fire grate, crossbeam formula fire grate, louver stoker, its pluses and minuses are structurally respectively arranged, respectively there is an axis hole at its each fire grate segment two ends of continuous band fire grate, fire grate is worn into fire grate by some gardens steel with screening, screening will be subjected to the pulling force that transmitted by the garden steel in the work, and fire grate segment is often broken; Crossbeam formula fire grate, fire grate segment are that vertical direction is settled, and metal wastage is big, install to make and have relatively high expectations; Louver stoker, screening are installed poor rigidity, screening in groups usually takes place come off and block accident.
The purpose of this utility model is to attempt to overcome the shortcoming of above-mentioned fire grate, and a kind of novel chain fire grate for ease of maintenaince simple in structure, durable is provided.
The utility model is design like this:
Hedgehog formula traveling-grate stoker is made up of coal bunker, meter gear wheel, active chain link, fire grate segment, sealing air compartment, casing etc., one end of fire grate segment is cast with installing hole, one group of screening is fixed on the active chain link at two ends with the garden steel, another head tower is by in one screening of back, pin hair as hedgehog, one fixedly the other end overlap mutually, make the fire grate upper surface form a transport plane.When screening moved to lower surface, each screening was the axle center with the stiff end, and under the gravity effect, upset is vertical shape automatically, and the cinder that will burn in backhaul is sent in the slag case.When fire grate forwarded upper surface to, screening automatically reset again, and the coal of coal bunker is sent into burner hearth.
The utility model is not subjected to pulling force because screening is an end bearing in the work, overcome the shortcoming that continuous band fire grate is easily broken.Its two because fire grate segment tipped upright during backhaul, automatic ash removing, fire grate do not have idle running and have saved the auxiliary equipment mucking machine.Its three because screening is turning, make fire grate become open type by enclosed type, can be observed situation in the stove, convenient for maintaining.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a hedgehog formula fire grate general structure schematic diagram.
Fig. 2 is the movable furnace grate plate structure chart.
Fig. 3 is a fire grate drive chain ring component installation diagram.
As described in Figure 1, fire grate is mainly by groups such as coal bunker 1 gear wheel 3, active chain link 4, activity screening 5, sealing air compartment 8, casings 9.Pair of right and left meter gear wheel drives initiatively chain link rotation under the effect of reductor, be contained in the middle fire grate segment combination of two active chain links along with the complete machine motion.One plate 2 is arranged on the coal bunker 1, the flow of control coal, the coal bunker right side has a restorer 10 to help moving grate to reset.
Be convenient for maintaining, initiatively install a quick change steel bushing 6 additional in the middle of chain link pilot hole and the garden steel 7, when needs taking-up garden steel keeped in repair a certain joint screening group, initiatively chain link can keep original assembly relation.
When the foundry furnace screening, in the bottom surface of screening, be cast into iron wire 11, its effect is when screening is assembled, every group of screening can couple together adjacent screening with iron wire, the globality during with increase work.
The utility model has designed sealing air compartment 8, has replaced original wind isolation board, thereby prevents the problem of leaking out effectively, and can collect the leakage coal that falls down from grate surface in the combustion process.
During fire grate work, the upper surface fire grate is taken mutually and is leaned on, and forms a transport plane.The coal of coal bunker is sent into burner hearth automatically along with the running of fire grate.During the fire grate backhaul, screening transfers vertical automatically to, and the slag that flows into casing is sent in the slag case.
Claims (4)
1, a kind of hedgehog formula traveling-grate stoker, comprise coal bunker, meter gear wheel, active chain link, fire grate segment, sealing air compartment, casing etc., it is characterized in that fire grate segment is that an end is cast with installing hole, and one group of screening is fixed on the active chain link at two ends with the garden steel, another head tower leans against in one screening of back, makes the fire grate upper surface form a transport plane, when screening moves to lower surface, each screening is the axle center with the stiff end, is turned into vertical automatically.
2, hedgehog formula traveling-grate stoker according to claim 1 is characterized in that installing a quick change steel bushing additional between the active chain link of fire grate and the garden steel.
3, hedgehog formula traveling-grate stoker according to claim 1 is characterized in that the bottom surface of fire grate segment is cast with the iron wire that the adjacent screening of connection is used.
4, hedgehog formula traveling-grate stoker according to claim 1 is characterized in that also having a kiln envelope air compartment.
