Abstract
The utility model relates to a rear arch crown ash removing device for chain fire grate coal fired steam boiler, which is characterized in: both ends of the connecting rod are respectively connected with a slide cover plate by a connecting joint, a connecting bolt and a connecting nut; the connecting rod is passed through a bushing, then, both ends of the connecting rod are respectively connected with a slide cover plate and a pull bar by a connecting joint, a connecting bolt and a connecting nut; the bushing and lugs are respectively fixed on the rear faceplate of the boiler by welding. The utility model can remove the ash deposited on the rear arch crown of the boiler without shutting down the boiler, solves the problem of deposited ash coking on the rear arch crown of the boiler or high temperature smoke short circuit.
Description
One, technical field
The utility model relates to dome portions deashing device behind a kind of traveling-grate stoker coal-fired steam boiler.
Two, background technology
1, the state of the art of like product
At present, the back chimney arch of DZL4t/h traveling-grate stoker coal-fired steam boiler burner hearth inside is to build by laying bricks or stones by the refractory concrete cast or with moulding refractory brick to form, its structure has two kinds, a kind of is totally enclosed (promptly not having ash-falling hole), another kind is at forward and backward position, and and arranged on left and right sides respectively leaves two rectangular ash-falling holes.
2, shortcoming
Totally enclosed (promptly not having ash-falling hole) back its shortcoming of chimney arch is: because dust stratification is deposited on the top of back chimney arch front end, the dust stratification fusing at burner hearth action of high temperature lower front end top forms coking to boiler, stops up exhaust gases passes boiler can't be moved in running.
At forward and backward position, its shortcoming of back chimney arch that and arranged on left and right sides respectively leaves two rectangle ash-falling holes is: thermal-flame and high-temperature flue gas form short circuit by four rectangular ash-falling holes under the effect of air-introduced machine, influence boiler combustion and cause the boiler output deficiency, the thermal efficiency reduces.
Three, Fa Ming content
1, the utility model is a dome portions deashing device behind a kind of traveling-grate stoker coal-fired steam boiler of employing, behind chimney arch top dust stratification behind the boiler, does not need blowing out then can remove, dust stratification coking or this problem of high-temperature flue gas short circuit at chimney arch top behind the solution boiler.
2, the utility model adopts following technical scheme:
Dome portions deashing device behind a kind of traveling-grate stoker coal-fired steam boiler, it is characterized in that: the two ends of connecting rod (5) are connected with slide cover (1) by jointing (2), connecting bolt (3), attaching nut (4) respectively, after connecting rod (6) passes sleeve pipe (7), two ends are connected with pull bar (8) with slide cover (1) by jointing (2), connecting bolt (3), attaching nut (4) respectively, and sleeve pipe (7), journal stirrup (9) are welded on respectively on the boiler rear board (10) and fix.
Operation principle:
Boiler slide cover (1) in running covers on the ash-falling hole (12) of chimney arch behind the boiler (11), when the dust stratification at chimney arch top need be removed after dropping to boiler, to draw back pull bar (8) and slide cover (1) be left ash-falling hole (12) by connecting rod (5), connecting rod (6), do not need under the boiler situation out of service at boiler like this, just can make that the dust stratification at chimney arch (11) top drops on the traveling-grate stoker naturally by ash-falling hole (12) behind the boiler, discharge out of the furnace by slag remover.To promote pull bar (8) after removing finishes and slide cover (1) be covered ash-falling hole (12) deashing constipation bundle by connecting rod (5), connecting rod (6).
3, the advantage of the invention, technical characterstic, result of use benefit.
1., the back chimney arch that solves totally-enclosed (promptly not having ash-falling hole) is because of the dust stratification fusing forms the exhaust gases passes that back chimney arch front top is seriously stopped up in coking, and boiler can't be moved.
2., solve at forward and backward position, the back chimney arch that and arranged on left and right sides respectively leaves two rectangle ash-falling holes because of the flue gas short circuit, causes the boiler output deficiency in boiler operatiopn, the thermal efficiency reduces.
3., reach boiler and need not close the purpose that air blast and air-introduced machine (i.e. not blowing out) can be removed chimney arch top, back dust stratification.
Technical characterstic is a compact conformation, is convenient to make.Result of use is very convenient.
Four, description of drawings:
Fig. 1 is the utility model sectional structure schematic diagram
Fig. 2 is the utility model plan structure schematic diagram
Among the figure: the 1-slide cover; The 2-jointing; The 3-connecting bolt; 4-attaching nut; The 5-connecting rod; The 6-connecting rod; The 7-sleeve pipe; The 8-pull bar; Chimney arch, 12-ash-falling hole are formed behind 9-journal stirrup, 10-rear board, the 11-boiler.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Jointing (2) is poured into a mould simultaneously with refractory concrete by figure processing back and slide cover (1) with heat-resistance stainless steel and is become one, consists of slide cover (1).Connecting rod (5), connecting rod (6) adopt heat-resistance stainless steel by figure processing, and connecting bolt (3), attaching nut (4) select for use the heat-resistance stainless steel material market to buy, and sleeve pipe (7), pull bar (8), journal stirrup (9) ordinary carbon steel material are by figure processing.
Claims (1)
1, dome portions deashing device behind a kind of traveling-grate stoker coal-fired steam boiler, it is characterized in that: the two ends of connecting rod (5) are connected with slide cover (1) by jointing (2), connecting bolt (3), attaching nut (4) respectively, after connecting rod (6) passes sleeve pipe (7), two ends are connected with pull bar (8) with slide cover (1) by jointing (2), connecting bolt (3), attaching nut (4) respectively, and sleeve pipe (7), journal stirrup (9) are welded on respectively on the boiler rear board (10) and fix.
