Specific embodiment
Each step of the present invention is further illustrated with reference to the accompanying drawings and detailed description.
Molten salt chlorination furnace bottom biock building method includes step A~I.
Step A building construction platform 1 as shown in Figure 1: guarantees 1 surface levelness of operation platform and flatness.Operation platform
1 uses soft clay fire resisting brick masonry, and there is certain degree of hardness and intensity to guarantee load-bearing；Also there is certain can be processed simultaneously
Property, being able to use hand-held scraper or abrasive machine carries out polishing its levelness of guarantee and flatness to 1 surface of operation platform, can also protect
Card can process suspender groove 5 in the next steps.1 flatness of operation platform should be not more than 2mm.
Step B: production suspender 2, suspender 2 include suspender bottom plate 2-1, suspender bar 2-2 and hanging ring 2-3, suspender bar 2-2 with hang
Tool bottom plate 2-1 is vertical, and suspender bottom plate 2-1 and hanging ring 2-3 are connected to the both ends suspender bar 2-2.Specifically, as shown in Fig. 2, bottom
Plate 2-1 is cut by steel plate, and according to stress condition, bottom plate 2-1 can be made into different size, and suspender bar 2-2 and hanging ring 2-3 are by justifying
Steel is made, round steel top circumflexion, forms hanging ring 2-3；Round steel lower end bent jointing is on bottom plate 2-1.Suspender bar 2-2's
After the completion of length should meet subsequent step masonry, hanging ring 2-3 exposes.
Step C is as shown in Figure 3: unwrapping wire determines circular masonry region 4 and divides equally region 4 is built on operation platform 1
At the small masonry region 4-1 of four a quarter circles；In each small masonry region 4-1, it is recessed on operation platform 1 to output suspender
Slot 5；One layer of paper washer 3 is laid on operation platform 1 again, and outputs on paper washer 3 and passes through with the one-to-one suspender of suspender groove 5
Hole 6.It is identical as Molten salt chlorination furnace bottom block size to build 4 size of region.The effect of paper washer 3 is easy for after the completion of masonry, salt chlorine
Change furnace bottom to separate with operation platform 1.2 distribution situation of suspender is as shown in figure 3, there are three hang tool in each small masonry region 4-1
Tool 2, suspender 2 are located in the middle part of small masonry region 4-1；It is larger by paracentral suspender bottom plate 2-1, the suspender bottom plate 2-1 of outside compared with
It is small；The angle of hanging ring 2-3 is 120 °.
Step D: being put into suspender groove 5, fixed spreader bottom plate 2-1 for suspender bottom plate 2-1, and guarantees that suspender 2 is vertical；Paper washer
On 3, it is vertically arranged spacer 7 in the adjacent small junction for building region 4-1,7 cross-sectional shape of spacer is cross, interval
Part 7 separates masonry region 4-1 four small.Spacer 7 is separated out masonry region 4-1 four small, to build out four bottom biocks point
Body 11, convenient for guaranteeing the bottom biock form accuracy after seperated 11 form accuracies of bottom biock and assembly；Bottom biock is divided into four bottoms
Portion's block fission 11, convenient for hanging in Molten salt chlorination furnace.Spacer 7 is made of aluminium alloy.Suspender bottom plate 2-1 does not have to operation platform 1
It fixes very secured, avoids being difficult to separate in subsequent step, filled out between suspender bottom plate 2-1 and suspender groove 5 with refractory wass
?.
Step E: masonry 9 is successively built in small masonry region 4-1 and forms multiple bottom biock layers 10, the arrangement shape of masonry 9
Formula is herringbone, and 9 fissure of displacement of masonry of adjacent base block layer 10 is built；Be provided on two bottom biock layers 10 of the top with
The corresponding preformed hole 8 in the position suspender bar 2-2 is provided with suspender bar corresponding with the suspender position bar 2-2 on remaining bottom biock layer 10
Hole 12, filling fire resisting material between suspender rod aperture 12 and suspender bar 2-2；Each bottom biock layer 10 obtains four bottoms after the completion of building
Block fission 11.Gray seam thickness is 1-2mm between masonry 9.Masonry 9 at the position suspender bar 2-2 cuts out suspender rod aperture with brick cutting machine
12, it is every to have built one layer of bottom biock layer 10, its flatness, thickness plumb bob, horizontal ruler cooperation are checked with guiding ruler cooperation level meter
Tape measure inspection carries out the masonry of next layer of bottom biock layer 10 after passed examination.The preformed hole 8 of top layer's bottom biock layer 10 can compare
The preformed hole 8 of the bottom biock layer 10 of its lower layer is big.The quantity of bottom biock layer 10 is eight layers.
Step F: drying bottom biock fission 11.Usual manner drying bottom biock fission 11 can be used, it can also be flat in construction
The lower setting drying unit of platform 1 is dried.
Step G: hooking hanging ring 2-3 using lifting tool and sling, and each bottom biock fission 11 is hung in Molten salt chlorination furnace, and group
At circle；During lifting, paper washer 3 seperated with bottom biock 11 is separated, and suspender bottom plate 2-1 is separated with operation platform 1, suspender bottom plate
The de- firmly bottom biock fission 11 of 2-1.
Step H: suspender bar 2-2 is cut off from 8 bottom of preformed hole, then fills up preformed hole 8 with refractory material.Refractory material
It fills up preformed hole 8 i.e. and can guarantee seperated 11 surfacings of bottom biock, and can avoid bottom biock and lead to along boom hole shape 12 at downward
Seam.
Step I: the filling fire resisting material between bottom biock fission 11, so that bottom biock fission 11 is connected to form fused salt
Chlorination furnace bottom biock.
