At present, the air-distribution board mount on fluidized bed furnace is conventionally by workWhat word molten steel was flat be welded on inboard wall of furnace body forms; Boiling section operating temperature is higher in fluidized bed furnace, conventionally between 850-1100 DEG C,Being heated for a long time, in cooling process, I-steel is because the effect of expanding with heat and contract with cold frequently very easily deforms; Due to I-steel twoEnd is all welded on inboard wall of furnace body, therefore distortion mainly occurs in vertical direction, causes that I-steel is irregular to arch upward, and causes wholeFrame surface is no longer smooth, thereby causes the dispersion plate distortion being placed on support, causes a point wind inequality, often dead stove, shadowThe normal operation that has rung fluidized bed furnace, causes economic loss.
Utility model content
The purpose of this utility model is to provide a kind of fluidized bed furnace, easily deforms with the air-distribution board mount that solves existing fluidized bed furnaceAnd then cause dispersion plate distortion, cause the problem of a point wind inequality, often dead stove.
The utility model solves the technical scheme that its technical problem adopts: fluidized bed furnace, comprise body of heater, in body of heater, be provided with intoMaterial mouth, discharging opening, bottom of furnace body is provided with the air inlet being connected with blower fan, and upper of furnace body is boiling section, and lower portion of furnace body is air compartment,Boiling section and air compartment separate by dispersion plate, are horizontally disposed with the support of placing dispersion plate on body of heater, and support is by someRoot girder steel composition, one end of described girder steel is fixedly connected with body of heater, and the other end connects with the compensator being fixedly installed on inboard wall of furnace bodyConnect, on the inboard wall of furnace body of support lower end, be provided with the ring-type gusset for supporting bracket.
Wherein, compensator is made up of the first sleeve, the second sleeve, spring, and described the first sleeve and the second sleeve are one end envelopeClose, the tubular structure of an end opening, the two ends of spring are solid with the first sleeve inner bottom part center, the second sleeve inner bottom part center respectivelyFixed connection, the external diameter adaptation of the internal diameter of the first sleeve and the second sleeve, the first sleeve is relative with the second sleeve openings direction, and firstThe bottom of sleeve is fixedly connected with inboard wall of furnace body, and the bottom of the second sleeve is fixedly connected with one end of girder steel.
The beneficial effects of the utility model are: air-distribution board mount is made up of some girder steels, and one end and the body of heater of girder steel are fixedConnect, the other end is connected with the compensator being fixedly installed on body of heater, and in the time that girder steel expands with heat and contract with cold, compensator is in level sideTo giving girder steel with compensation, thereby reach the object of avoiding girder steel to be out of shape, to arch upward at vertical direction, ensured support integral surfacePlanarization, thereby avoided being placed on the distortion of dispersion plate on support; Compensator is made up of two sleeves and spring, letterSingle practical, convenient installation; On the inboard wall of furnace body of support lower end, be provided with ring-type gusset, support entirety has been played to support, reinforcingEffect.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1 and Figure 2, the utility model fluidized bed furnace, comprises body of heater 1, is provided with charging aperture, discharging opening on body of heater 1,Body of heater 1 bottom is provided with the air inlet being connected with blower fan, and body of heater 1 top is boiling section, and body of heater 1 bottom is air compartment, boiling sectionSeparate by dispersion plate 2 with air compartment, be horizontally disposed with the support of placing dispersion plate 2 in body of heater 1, support is by someRoot girder steel 3 forms, and one end of described girder steel 3 is fixedly connected with body of heater 1, the other end be fixedly installed on body of heater 1 inwallCompensator 4 connects, and on body of heater 1 inwall of support lower end, is provided with the ring-type gusset 5 for supporting bracket. When girder steel 3 is heatedExpand, entire length is elongated, compression compensation device 4; When girder steel 3 is cooling, length returns to normal length, compensator 4 withReturn to normal condition; Compensator 4 has played in the horizontal direction the effect of compensating length in the time that girder steel 3 expands with heat and contract with cold, fromAnd reach the object of avoiding girder steel 3 to be out of shape, to arch upward at vertical direction, ensure the planarization of support integral surface, thereby avoidedThe dispersion plate 2 that is placed on support be out of shape; Ring-type gusset 5 has played the effect of support, reinforcing to support entirety. ?Frame can be two groups of double-layer structures up and down that girder steel 3 cross welds form as shown in Figure 3, can be also one group of steel as shown in Figure 4Beam 3 is uniformly distributed one deck structure forming.
