Description
Technical field
The utility model relates to charcoal element production equipment fields, and in particular to a kind of furnace cover structure of carbon calcination single-unit furnace.
Background technique
Calcining furnace is one of the main Thermal Equipment of charcoal element production, belongs to high energy-consuming industry stove equipment, existing calcining
Furnace is largely horizontal type structure, also there is the vertical structure of small part small volume, and bell is made of steel skeleton and refractory material,
In actual production use process, bell hot face temperature reaches 140 degrees Celsius or more, and heat loss is larger, and service life
It is shorter.
In recent years, after especially 2005, with new material, the exploitation and application of new technology, the bell of calcining furnace is most
It is made using ceramic fiber module anchoring installation, has thermal coefficient small, the advantages that capacity is low, and heat energy loss is small, but one
Secondary property cost is higher, and before 2005, calcining furnace bell is substantially and is formed using fire-resistant light clay brick masonry, state
Interior most of Tan Su enterprises are still using so far, its advantage is that low cost, easy construction, but the disadvantage is that refractory brick thermal coefficient compared with
Height, and increase with the raising of furnace chamber temperature, in long term high temperature use process, refractory brick contraction distortion occurs between each other
Gap causes the loss of furnace chamber negative pressure larger, and thermal losses is more, causes energy excess waste.
Therefore, carbon industry constantly gropes the construction technology of calcining furnace bell, constantly brings forth new ideas, and takes a series of
Measure carries out isothermal holding to it, is covered on light-weight brick using with diatomite brick earliest, and advantage is lighter in weight,
But globality is poor, poor sealing, superseded；Followed by uniformly smeared using lightweight pouring material on refractory brick surface, it is excellent
Point is that globality is preferable, also preferable using initial stage bell thermal-insulating sealing, but with the variation repeatedly of production temperature, castable is anti-
Thermal shock resistance is poor, phenomena such as cracking, fall off occurs, heat insulation effect is not achieved；The common heat preserving mode of calcining furnace bell is at present
Smearing covering is carried out on refractory brick surface using quality silicate composite thermo-insulating material, it is by refractory fibre powder, additive, bonding
The composition such as agent, heat insulation effect is good, but the disadvantage is that intensity is lower, easy to fall off, service life is shorter.
CN103591805B discloses a kind of ring type roasting furnace cover and preparation method thereof, and furnace cover structure includes steel construction
Ogive is equipped on skeleton, the composite heat-insulating layer on ogive, ogive is built by several pieces of lightweight heterotypic fire bricks, is protected
Warm layer includes alumina silicate fibre layer, metallic sieve and sealant, which has certain sealing performance, refractoriness and anti-erosion
The advantages that performance, long service life, but the quality of patent entirety or heavier, it has not been convenient to it is opened, closed procedure, it should
The insulating layer of patent is exposed, both will lead to insulating layer and has received destruction, is also easy to produce deformation, and refractory brick building process is also time-consuming and laborious,
It is also higher to the brick-building art requirement of worker, it is undesirable that final size is slightly easily led to without paying attention to, and the patent exists
Also be inconvenient to the operation such as carry out aperture, assemble other ancillary equipments on bell, service life is also up for further improving.
