Description

Repairing structure of hot air pipeline top refractory
Technical Field
The utility model relates to a hot-blast main roof refractory's repair structure.
Background
The hot air pipeline is a common pipeline in the rotary kiln process of the chain grate and is a conveying channel of a hot air flow system. In order to ensure that the wall steel plate of the regenerative air duct does not contact high-temperature air flow and is not scoured, abraded and oxidized by material flow, the interior of a general pipeline is in a refractory spraying or smearing mode, and a 50mm coating can meet the requirement. And higher temperature pipelines such as: the hot air pipeline from the circular cooler to the kiln head cover of the rotary kiln is integrally cast, and the thickness of the casting material layer is 250 MM. When a production line is newly built, when a hot air pipeline from the circular cooler to a kiln head cover of a rotary kiln is constructed, anchoring nails (with the distance of 200 MM) are welded firstly, then a layer of aluminum silicate fiberboard with the thickness of 30MM is laid, and finally, mullite castable (HD-MJ 65) is used for integral pouring construction. The top castable can partially fall off due to long-term high-temperature airflow scouring and oxidation in the production process, and the castable is not only not easy to be combined with the top anchoring piece due to the fact that the top falls off and the material layer is thick when the top castable is locally repaired, but also is not easy to form a whole with the peripheral old castable and can easily fall off even if the top castable is poured. The repairing effect is not ideal. From the aspect of safety, the pipeline needs to be drilled into during construction, and the limited space operation has great potential safety hazard.
Disclosure of Invention
An object of the utility model is to provide a hot-blast main top resistant material repair structure, safe and reliable, the construction is simple, and is durable firm, and the life is long.
The utility model aims at realizing like this, a hot-blast main top resistant material's repair structure, including the peripheral pipeline that is located the rotary kiln top, the suit is setting up the steel form sleeve pipe at the outer interval suit of rotary kiln hood and kiln hood backheat tuber pipe respectively, and the intussuseption of steel form sleeve pipe is filling and is being set up the mullite pouring material, wherein the side by side interval is setting up three anchor nail in the pouring material at kiln hood backheat tuber pipe top, and the anchor nail is hung through wire rope peripheral pipeline on.
The top of a hot air pipeline is repaired by adopting an anchoring brick hanging scheme, an upper steel plate at the repaired position is cut off, a hanging brick support is manufactured by utilizing pipelines around the steel plate, a steel template is connected to the bottom of the steel template, and the anchoring brick is installed for pouring. The method is constructed externally, is safe and reliable, simple in construction, firm and long in service life.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the structure of the present invention.
Detailed Description
A repairing structure of a hot air pipeline top refractory is shown in figure 1 and comprises a peripheral pipeline 8 located above a rotary kiln 1, steel formwork sleeves 2 and 4 are respectively sleeved outside a rotary kiln head and a kiln head regenerative air pipe at intervals, mullite castable 3 and mullite castable 6 are filled in the steel formwork sleeves 2 and 4, three anchoring nails 7 are arranged in the castable at the top of the kiln head regenerative air pipe 5 side by side at intervals, and the anchoring nails 7 are hung on the peripheral pipeline 8 through steel wire ropes.
