Abstract

A kind of fluidized bed furnace wall reinforcement drag hook, it is characterized in that: comprise steel plate (3), drag hook one (2), drag hook two (4), described drag hook one (2) is heat resisting steel drag hook, drag hook two (4) is stainless steel drag hook, the shape of drag hook two (4) is " L " type, and " L " type minor face afterbody is provided with moving part; Drag hook one (2) is connected with drag hook two (4), and drag hook one (2) is connected with steel plate (3).The utility model is simple and reasonable, can delay fluidized bed furnace deformation of wall, and extend the repair time, workload is little, and efficiency is high.

Description

A kind of fluidized bed furnace wall reinforcement drag hook
Technical field
The utility model relates to a kind of drag hook, particularly relates to a kind of fluidized bed furnace wall reinforcement drag hook.
Background technology
Current factory uses Huangshi sky to reach the thermal source of fluidized bed furnace as gypsum board manufacture, and fluidized bed furnace model is ZXEDFR16.In fluidized bed furnace long-play process, fluidized bed furnace fire box temperature maintains more than 900 DEG C operations for a long time, it is refractory brick that body of wall due to fluidized bed furnace consists of inner, outside is ordinary red brick, gap filling perlite between refractory brick and ordinary red brick, after this kind of structure long-play, owing to expanding with heat and contract with cold and the inner reason keeping negative pressure for a long time, body of heater can distortion gradually, along with the increase of service time, deflection can strengthen gradually, causes the inner body of wall of fluidized bed furnace to have the risk of caving in, stop production to overhaul of for this reason having to after deformation of wall is excessive.Internal refractory brick and insulating brick are removed after during maintenance, whole furnace roof needs dismounting, whole time time between overhauls(TBO) is long, and workload is large, and capital expenditure is large.In order to slow down this deformation of fluidized bed furnace body of wall, therefore needing to reinforce when overhauling whole fluidized bed furnace body of wall, reaching the effect delaying fluidized bed furnace deformation of wall.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the utility model provides a kind of simple and reasonable, reinforcing drag hook that can delay fluidized bed furnace deformation of wall.The technical solution adopted in the utility model is as follows:
A kind of fluidized bed furnace wall reinforcement drag hook, comprise steel plate, drag hook one, drag hook two, described drag hook one is heat resisting steel drag hook, and drag hook two is stainless steel drag hook, and the shape of drag hook two is " L " type, and " L " type minor face afterbody is provided with moving part; Drag hook one is connected with drag hook two, and drag hook one is connected with steel plate.
Further, described steel plate is heat-resisting steel sheet and plate, heat-resisting more than 500 DEG C.
Further, the shape of described drag hook one is " L " type, and the long limit of " L " type is through steel plate.
Further, the shape of described drag hook one is T-shape, and the long limit of T-shape is through steel plate.
Further, the top of described drag hook one is provided with manhole, and described drag hook two minor face is connected with drag hook one through through hole.
Further, the minor face of described steel plate and described drag hook two be arranged in parallel.
Fluidized bed furnace wall reinforcement drag hook of the present utility model, can delay fluidized bed furnace deformation of wall, and extend the repair time, workload is little, and structure is simple simultaneously, and efficiency is high.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.As shown in Figure 1, fluidized bed furnace wall reinforcement drag hook of the present utility model, comprises steel plate, drag hook 1, drag hook 24, described drag hook 1 is heat resisting steel drag hook, drag hook 24 is stainless steel drag hook, and the shape of drag hook 24 is " L " type, and " L " type minor face afterbody is provided with moving part; Drag hook 1 is connected with drag hook 24 by the through hole 5 on its top, and the shape of drag hook 1 is " L " type, and the minor face 1 of " L " type is connected with steel plate 3.
Carry out, in dismounting maintenance, first thoroughly removing the refractory brick of fluidized bed furnace internal modification, carrying out again in building process at fluidized bed furnace, use water drilling by saturating for outside common brick wall drill, pitch-row diameter 50mm, is stretched out stainless steel drag hook by this cavity, can be freely movable.The intermediate active part of stainless steel drag hook and heat resisting steel drag hook is placed between refractory brick and outside common brick, afterbody heat-resisting steel sheet and plate and heat resisting steel drag hook is embedding builds in inner body of wall refractory brick, after building end by laying bricks or stones, whole heat-resisting body of wall and outside common brick wall are fixed together by the stainless steel drag hook by fixedly reaching outside outside fluidized bed furnace body of wall, reach the object that inner heat-resisting body of wall slows down distortion.Burner hearth internal high temperature is mainly considered in the design of this drag hook, external temperature is relatively on the low side, and have relative movement owing to expanding with heat and contract with cold between internal refractory brick and outside common brick, therefore inner employing heat-resisting steel sheet and plate and heat-resisting reinforcing bar drag hook, the outside stainless steel drag hook that adopts prevents corrosion, and the Activities Design of middle drag hook can avoid the relative movement of external and internal wall and the destruction to whole body of wall.
