Abstract
The present invention provides one kind of rotary kiln with short lining producing period, simple production process, easy construction and maintenance, long service life and high heat efficiency. The rotary kiln includes a cylinder, a heat isolating layer and a furnace lining. The furnace lining consists of refractory bricks fixed with anchoring parts onto the cylinder, and the anchoring part has two hooks inserted into the holes in the refractory bricks in one end and the other end welded to the cylinder. The seams between refractory bricks are sealed with deposited material or interface bricks.
Description
Technical field
The invention belongs to a kind of rotary kiln, be specifically related to its furnace lining structure and improve, mainly be applicable in the roasting apparatus such as metallurgy, chemical industry, building materials.
Background technology
The method that the inside lining building of existing rotary kiln is commonly used basically has two kinds, and a kind of is the method that adopts refractory brick to build by laying bricks or stones by fissure of displacement block or circumferential weld.This method has following deficiency: 1) arch brick size head breadth difference is little, and brick and brick associativity are poor, easily fall brick; 2) build appearance and size tolerance strictness by laying bricks or stones to brick; 3) the little difficulty of construction of brickwork joint is big, long construction period; 4) along with the prolongation of running time, the wear extent of brick acquires a certain degree, and the brick and the accident of subsiding easily just fall.Second method is with prefabricated anchored brick and water the mode of material feeding combination, i.e. prefabricated anchored brick, and one is watered material feeding.This method also has following deficiency: 1) prefabricated anchored brick is that inner arrangement of reinforcement sponson and kiln shell weld together, and waters casting weldering anchoring piece earlier, the back cast, and arrangement of reinforcement is nearer from the high-temperature region in the prefabricated anchored brick, and it is big to conduct heat, and barrel temperature is increased, and radiation loss is big.2) coefficient of expansion of the thermal expansion of the interior arrangement of reinforcement in the prefabricated anchored brick and refractory material is inconsistent, and muscle expands prefabricated section is damaged, and influences the prefabricated section life-span; 3) fabrication cycle is longer, and manufacture craft is comparatively complicated, the cost of manufacture height.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the shortcoming that above-mentioned prior art exists, and provides a kind of its furnace lining manufacturing cycle short, produces simply construction, maintenance, easy to maintenance, long service life, the rotary kiln that the thermal efficiency is high.
Rotary kiln of the present invention, comprise cylindrical shell, thermal insulation layer and furnace lining, it is characterized in that described furnace lining is fixed on the cylindrical shell by anchoring piece by refractory brick, on two faying faces consistent of installation site on the refractory brick, have hook hole and hook concave surface with the rotary kiln tubular axis direction.Anchoring piece one end is provided with two hooks, hooks respectively in the hook hole of aforementioned adjacent two refractory brick, and the other end of anchoring piece is welded on the cylindrical shell for the welding body, and the interface of refractory brick is with watering the sealing of material feeding or interface brick in a circumference.
As a further improvement on the present invention, described watering is provided with the anchor studs that is welded on the cylindrical shell in the material feeding, and on four faying faces, adjacent two faces are provided with the wedge-shaped impression of concavo-convex engagement between brick and the brick on the described refractory brick, and two faces are provided with wedge-shaped bead in addition.Described refractory brick is that the cross section is the cuboid or the square of isosceles trapezoid.Described thermal insulation layer is a fire-retardent fiber felt-rug.
The present invention is because every brick is fixed by anchoring piece with cylinder of rotary kiln, and fixedly the anchoring piece of brick is far away from the high-temperature region, few by heat conducting heat like this, particularly is filled with thermal insulation layer between cylindrical shell and the refractory brick, the minimizing radiation loss; It is through behind the machine moulding that refractory brick is made, form in high-temperature roasting, and refractory brick intensity height, the life-span is long, and refractory brick is with short production cycle simultaneously, and processing cost is low; Whole rotary kiln refractory lining is cast-in-place few, has reduced construction, maintenance, maintenance difficulties.In addition, because four faying faces of refractory brick are provided with wedge shape tongue and groove edge, engagement is tight, good integrity, the furnace lining overall sealing performance has obtained reinforcement, reduced the probability that causes the furnace lining large tracts of land to be damaged because a small amount of refractory brick is destroyed, prolonged the service life of furnace lining, also increased the service life of whole rotary kiln, economic benefit is improved.

The specific embodiment
As shown in Figure 1, 2, rotary kiln of the present invention, comprise cylindrical shell 1, thermal insulation layer 2 and furnace lining, furnace lining is fixed on the cylindrical shell 1 by anchoring piece 4 by refractory brick 3, has hook hole 31 and hook concave surface 32 (see figure 3)s on two faying faces consistent with the rotary kiln tubular axis direction of installation site on the refractory brick 3.Referring to Fig. 5,6,7, anchoring piece 4 one ends are provided with two hooks 41, hook respectively in the hook hole 31 of aforementioned adjacent two refractory brick, and the other end of anchoring piece 4 is welded on the cylindrical shell 1 for welding body 42, and the interface of refractory brick 3 connects with watering material feeding 5 in a circumference.Water and be provided with the anchor studs 6 that is welded on the cylindrical shell 1 in the material feeding 5.
Shown in Fig. 3,4, on four faying faces, adjacent two faces are provided with the wedge-shaped impression 33 for concavo-convex engagement between brick and the brick on the refractory brick 3, and two faces are provided with wedge-shaped bead 34 in addition.Refractory brick 3 also can be the square of isosceles trapezoid for the cross section is the cuboid of isosceles trapezoid.Thermal insulation layer 2 is a fire-retardent fiber felt-rug.
