Abstract
The utility model relates to a heat accumulating type heating furnace, in particular to a heat accumulating type steel pushing heating furnace wall structure which comprises a furnace protecting steel plate, a thermal insulating layer and a fireproofing material layer. Anchoring nails and anchoring hooks are welded on the furnace protecting steel plate in a spaced mode, and anchoring bricks are horizontally suspended on the anchoring hooks. The heat insulating layer is an aluminum silicate fiber blanket, the aluminum silicate fiber blanket penetrates through the anchoring bricks and the anchoring nails and is adhered to the furnace protecting steel plate, the outer layer of the aluminum silicate fiber blanket is covered wholly by a steel wire mesh, and the steel wire mesh is welded and fixed and pressed by pressing plates and the anchoring nails, the fireproofing material layer is poured on the outer side of the steel wire mesh, and the fireproofing material layer and the thermal insulating layer are combined into a whole. According to the heat accumulating type steel pushing heating furnace wall structure, a traditional four-layer furnace wall structure is replaced by a three-layer structure, and an insulating layer is avoided. The phenomenon of firing on the connecting position of the furnace protecting steel plate and the furnace wall in the process of production is effectively avoided, heat efficiency of the heating furnace is guaranteed, heat loss is reduced, energy consumption is saved, intensity and durability of the furnace wall are enhanced, and service life of the heating furnace is prolonged.
Description
Technical field
The utility model relates to recuperative heater, specifically a kind of regenerative pusher type reheating furnace furnace wall structure.
Background technology
Tradition recuperative heater furnace wall structure is divided into from the inside to the outside: flame retardant coating, heat-insulation layer, heat insulation layer and furnace retaining steel plate, and the combination of each layer of furnace wall is not tight, and globality is relatively poor.Especially the heat-insulation layer that is consisted of by insulating brick, under the lasting high temperature resistant state, easily aging and be out of shape, the brickwork joint place produces the slit, make furnace retaining steel plate and furnace wall binding site the phenomenon of burning with anger often occur, gently then the furnace retaining steel plate is burnt red stain shape, heavy then cause furnace wall to tilt and collapse, namely increase the body of heater heat loss, can shorten again the service life of heating furnace.
The utility model content
The utility model is intended to solve the drawback that traditional recuperative heater furnace wall structure exists, and provides a kind of minimizing heat waste, energy efficient, the regenerative pusher type reheating furnace furnace wall structure of enhancing furnace wall intensity and durability.
The technical scheme that the described problem that solves the utility model adopts is:
A kind of regenerative pusher type reheating furnace furnace wall structure comprises furnace retaining steel plate, thermal insulation layer, refractory masses, and the interval is welded with anchor nails and anchoring hook on the described furnace retaining steel plate, and level hangs anchored brick on the anchoring hook; Described thermal insulation layer is alumina silicate fibre blanket, alumina silicate fibre blanket passes anchored brick and anchor nails is attached on the furnace retaining steel plate, the alumina silicate fibre blanket skin is by the whole bedding of steel wire, and being welded and fixed the compacting steel wire by pressing plate and anchor nails, the steel wire outside is cast with the refractory masses that is combined as a whole with thermal insulation layer.
Further, according to 200mm * 200mm spacing welding anchor nails, weld anchoring hook according to 400mm * 400mm spacing on the described furnace retaining steel plate; Described furnace retaining steel plate thickness is 8mm, and alumina silicate fibre blanket is threeply degree 120mm, refractory material layer thickness 354mm, furnace wall gross thickness 482mm.
Compared with prior art, the utility model has the advantages that: change four layers of furnace wall structure of traditional heating stove into three-decker, the cancellation heat-insulation layer, effectively prevented in the production process furnace retaining steel plate and the furnace wall binding site phenomenon of burning with anger, guarantee the thermal efficiency of heating furnace, reduced heat loss, saved energy consumption, strengthen intensity and the durability of furnace wall, prolonged the service life of heating furnace.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram
Among the figure: 1-furnace retaining steel plate, 2-alumina silicate fibre blanket, 3-refractory masses, 4-steel wire, 5-anchored brick, 6-pressing plate, 7-anchor nails, 8-anchoring hook.
The specific embodiment
Below in conjunction with embodiment the utility model is further described.
Referring to Fig. 1, the basis of regenerative pusher type reheating furnace furnace wall take furnace bottom as furnace wall, it is 482mm that four layers of furnace wall structure gross thickness of furnace wall gross thickness and tradition remain unchanged, wherein: furnace retaining steel plate 1 thickness is 8mm; Thermal insulation layer adopts three layers of alumina silicate fibre blanket 2, gross thickness 120mm; Refractory material layer thickness 354mm.
At first on furnace retaining steel plate 1, weld anchor nails 7 according to 200mm * 200mm spacing, according to 400mm * 400mm spacing welding anchoring hook 8; Anchored brick 5 levels are hung on the anchoring hook 8, alumina silicate fibre blanket 2 is passed anchored brick 5 and anchor nails 7 is attached on the furnace retaining steel plate 1, outer with steel wire 4 whole bedding compactings, steel wire 4 is welded and fixed with the pressing plate 6 of anchor nails 7 usefulness 50mm * 50mm * 5mm.Lay template according to furnace wall refractory material 354 thickness, place corrugated plating and reserve dilatation joint, pouring fireproof material layer 3.Pouring fireproof material layer 3 casting and constructing are to begin upwards continuous pouring until the furnace wall top vibrates with vibrating head in the casting process at any time by furnace bottom, and note vibrating time.Check at any time and guarantee anchored brick 5 not deflection drop, guarantee not produce cavity, non-running pulp, template indeformable.
After the furnace wall construction is complete, in strict accordance with the heating furnace furnace wall baking temperature rise curve baking furnace wall of regulation.Temperature freely heats up after rising to 850 ℃.
