Abstract
The invention belongs to the technical field of fire-resistant material spraying and especially relates to a fire-resistant liner for a warm air pipeline and a paving method thereof. The fire-resistant liner comprises the warm air pipeline and is characterized by comprising a set of anchoring nails, a fire-resistant fiber felt and a spraying coating layer, wherein the anchoring nails are welded with an inner wall of the warm air pipeline; the fire-resistant fiber felt penetrates through the anchoring nails and is grafted with the inner wall of the warm air pipeline; and the spraying coating layer is sprayed and coated on the surface of the fire-resistant fiber felt. The structures, such as a fire-resistant stainless steel network and a quick clamping sheet, for fixing the fire-resistant fiber felt and the spraying coating layer during the paving process of the original fire-resistant liner for the warm air pipeline are omitted by the fire-resistant liner provided by the invention; the anchoring nails are used for fixing the fire-resistant fiber felt and the spraying coating; and under the condition of maintaining each performance index of the original fire-resistant liner, the spraying coating construction efficiency of the warm air pipeline is increased, the operation time is reduced and the service life of the warm air pipeline is prolonged.
Description
Technical field
The invention belongs to refractory material laying technology field, especially relate to a kind of hot air duct refractory lining and laying method thereof.
Background technology
The inwall of general grate kiln pelletizing production system hot air duct all is provided with refractory material; The pipeline refractory material is sprayed coating, fire-resistant white steel mesh, fire-retardent fiber felt-rug, pipeline outer wall from inside to outside; Wherein fire-retardent fiber felt-rug and sprayed coating all are to rely on the supporting role of fire-resistant white steel mesh fixing, and fire-resistant white steel mesh is again to rely on flash card etc. to fix than labyrinth.The fire-resistant white steel mesh twine of original structure cross section is thinner, and easy oxidation under the high temperature can't be played permanent effective supporting, causes hot air duct low service life.There is complex structure in the building method of above-mentioned hot air duct refractory material, and easy oxidation shortcoming such as come off, and it is more that flash card and fire-resistant white steel mesh are installed inconvenient required maintenance zero spare part, and construction and installation are inconvenient.
Summary of the invention
The purpose of this invention is to provide a kind of hot air duct refractory lining method, change original pipeline refractory material inner-wall spraying structure, improve efficiency of construction, prolong hot air duct service life.
The objective of the invention is to realize through following technical proposals:
Hot air duct refractory lining of the present invention; Comprise hot air duct; It is characterized in that comprising the one group of anchor studs that is welded on said hot air duct inwall, penetrate this group of anchor studs and abut against the fire-retardent fiber felt-rug of said hot air duct inwall, be sprayed on the sprayed coating on this fire-retardent fiber felt-rug surface; The double end end of described anchor studs top for being abutted against each other; The bottom is the single head end, and this single head end welds with said hot air duct inwall mutually, and the double end end on described anchor studs top separately and be pressed on the surface of said fire-retardent fiber felt-rug.
The double end end on described every adjacent two anchor studs tops separately direction is vertical each other.
The laying method of hot air duct refractory lining, its concrete grammar is:
(1) weld one group of anchor studs at the hot air duct inwall, the double end end of this anchor studs top for being abutted against each other, the bottom is the single head end, this single head end welds with said hot air duct inwall mutually;
(2) fire-retardent fiber felt-rug is laid on described one group of anchor studs, penetrates described fire-retardent fiber felt-rug and it is fixed on the described hot air duct inwall with the double end end of anchor studs;
(3) the double end end with anchor studs separates, and is pressed on the surface of described fire-retardent fiber felt-rug;
(4) sprayed coating in the surface spraying of described fire-retardent fiber felt-rug.
Advantage of the present invention:
The present invention has cancelled structures such as the fire-resistant white steel mesh that is used for fixing fire-retardent fiber felt-rug and sprayed coating when original hot air duct refractory lining is laid and flash card; Adopt anchor studs that fire-retardent fiber felt-rug is fixed; Under the prerequisite that does not change original refractory lining each item performance indications; Improve hot air duct spraying application efficient, reduced the activity duration, and prolonged hot air duct service life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the I portion zoomed-in view of Fig. 1 of the present invention.
Fig. 3 is the A-A view of Fig. 1 of the present invention.
The specific embodiment
Further specify the specific embodiment of the present invention below in conjunction with accompanying drawing.
Like Fig. 1,2 and shown in Figure 3; A kind of hot air duct refractory lining comprises hot air duct, it is characterized in that comprising the one group of anchor studs 3 that is welded on said hot air duct inwall 4; Penetrate this group of anchor studs 3 and abut against the fire-retardent fiber felt-rug 2 of said hot air duct inwall 4; Be sprayed on the sprayed coating 1 on these fire-retardent fiber felt-rug 2 surfaces, the double end end of described anchor studs 3 tops for being abutted against each other, the bottom is the single head end; And this single head end welds with said hot air duct inwall 4 mutually, and the double end end on described anchor studs 3 tops separates and be pressed on the surface of said fire-retardent fiber felt-rug 2.
The double end end on described every adjacent two anchor studs 3 tops separately direction is vertical each other, the reinforcement that this layout is convenient to fire-retardent fiber felt-rug 2 is fixed.
A kind of laying method of hot air duct refractory lining, its concrete grammar is:
(1) in one group of anchor studs 3 of hot air duct inwall 4 welding, the double end end of these anchor studs 3 tops for being abutted against each other, the bottom is the single head end, this single head end welds with said hot air duct inwall 4 mutually;
(2) fire-retardent fiber felt-rug 2 is laid on described one group of anchor studs 3, penetrates described fire-retardent fiber felt-rug 2 and it is fixed on the described hot air duct inwall 4 with the double end end of anchor studs 3;
(3) the double end end with anchor studs 3 separates, and is pressed on the surface of described fire-retardent fiber felt-rug 2;
(4) sprayed coating 1 in described fire-retardent fiber felt-rug 2 surface sprayings.
The present invention has cancelled structures such as the fire-resistant white steel mesh that is used for fixing fire-retardent fiber felt-rug 2 and sprayed coating 1 when original hot air duct refractory lining is laid and flash card; Adopt 3 pairs of fire-retardent fiber felt-rugs 2 of anchor studs to fix; Under the prerequisite that does not change original refractory lining each item performance indications; Improve hot air duct spraying application efficient 33%, reduced the activity duration, and prolonged hot air duct service life.
