Description
Technical field
The present invention relates to materials resistance on the outside of a kind of suspension cylinder cylinder body to protect lining mixing building method, and it is perpendicular to belong to the double thoraxes of suspension cylinder type
Kiln production equipment technology.
Background technique
Suspension cylinder type MAERZ lime kiln is a kind of common Industrial Stoves, is mainly used for calcined limestone, includes two cylinders
The vertical shaft of shape and cylinder-shaped suspension cylinder cylinder body when work, by the continuous charging into furnace, make lime stone (main component
CaCO3) quick lime (CaO) and carbon dioxide (CO are resolved under the high temperature conditions2).
Currently, the masonry in the air duct on the outside of suspension cylinder cylinder body is built with special form brick and castable.When masonry, hanging
The anchoring piece group that four groups of width are about 800mm is uniformly distributed on the circumference of cylinder cylinder body every 90 °, between with special-shaped brick masonry, so
It is filled afterwards in anchoring piece group position with castable, forms one side walls of annular passage.It is not cleavable that special form brick is built in this way,
It is big to build difficulty, it is big to build error；Secondly in production since the deformation of suspension cylinder cylinder body expanded by heating is big, lead to the resistance to material pine in outer ring
Dynamic, brick is easy to fall off；Furthermore special form brick purchase quantity is few, and scale error required precision is high, and purchase cost is big.
Summary of the invention
It is an object of the present invention to provide materials resistance on the outside of a kind of suspension cylinder cylinder body to protect lining mixing building method, in suspension cylinder cylinder body
It is poured two layers of castable using steel die block-by-block on outer circumference direction, reduces error caused by building, solves background technique
Present in the above problem.
The technical scheme is that
Resistance to material protection lining mixing building method on the outside of a kind of suspension cylinder cylinder body comprising the steps of:
1. the uniform fixed anchors in the outside of suspension cylinder cylinder body；
2. being poured lower layer's castable using steel die block-by-block on the circumferencial direction on the outside of suspension cylinder cylinder body, and adjacent at two pieces
Lower layer's castable between be arranged refractory ceramic fibre plate four；
3. being laid with refractory ceramic fibre plate two in lower layer's castable；
4. in lower layer's castable using steel die block-by-block be poured upper layer castable, and two pieces of adjacent upper layer castables it
Between be arranged refractory ceramic fibre plate one；
5. refractory ceramic fibre plate five is arranged in the outside of castable and lower layer's castable on upper layer.
The profile of the steel die cross section is the sector matched with suspension cylinder cylinder body, and fan-shaped side is equipped with one
Groove, the fan-shaped other side are equipped with a protrusion matched with groove.
The upper layer castable and lower layer's castable are mullite pouring material.
The thickness of the refractory ceramic fibre plate one and refractory ceramic fibre plate four is 3mm, refractory ceramic fibre plate two
With a thickness of 5mm, the thickness of refractory ceramic fibre plate three and refractory ceramic fibre plate five is 12mm.
The beneficial effects of the present invention are: being poured two layers on suspension cylinder cylinder body outer circumference direction using steel die block-by-block
Castable reduces error caused by building, simplifies building process, and can be avoided since suspension cylinder cylinder body expanded by heating becomes
The problems such as resistance to material in outer ring caused by after shape is loosened, is fallen off.

Specific embodiment
Below in conjunction with attached drawing, by example, the invention will be further described.
Referring to attached drawing 1-7, resistance to material protection lining mixing building method on the outside of a kind of suspension cylinder cylinder body comprising the steps of:
1. the uniform fixed anchors 13 in the outside of suspension cylinder cylinder body 9；
2. being poured lower layer's castable 4 using 10 block-by-block of steel die on the circumferencial direction in 9 outside of suspension cylinder cylinder body, and at two pieces
Refractory ceramic fibre plate 47 is set between adjacent lower layer's castable；
3. being laid with refractory ceramic fibre plate 23 in lower layer's castable 4；
4. being poured upper layer castable 1 using 10 block-by-block of steel die in lower layer's castable 4, and it is poured on two pieces of adjacent upper layers
