Description
Technical field
This utility model is related to metallurgy sintered pelletizing mechanical field, and more particularly, to a kind of the new of revolving drum dehydrator slips
Groove.
Background technology
Revolving drum dehydrator is the drying equipment that agglomerates of sintered pellets factory commonly uses, and is mainly used to be dried place to Iron Ore Powder
Reason, the moisture content reducing Iron Ore Powder is to OK range so as to disclosure satisfy that the requirement of agglomerates of sintered pellets production technology.Revolving drum dries
Dry owner will be made up of following sections：One is air stove, generally uses blast furnace gas useless as the high warm of combustion medium production
Gas（750℃-850℃）；Two is feed chute, and feed chute generally steel plate rolls welding processing and forms, and Iron Ore Powder etc. needs
The material being dried passes through air stove by upper funnel through feed chute and enters revolving drum drier；Three is that revolving drum is dried
Machine, Iron Ore Powder etc. needs dry material from import to exit movement from revolving drum drier, and with hot waste gas, heat occurs
Exchange；Four is kiln hood, plays sealing, discharges water vapour and discharging effect.
Feed chute passes through air stove at present, is subject to air stove high temperature heat radiation and hot waste gas to toast, because it adopts for a long time
Steel plate rolls welding processing and forms, so often there is steel plate temperature distortion, the problem of weld cracking, and chute interior abrasion
Seriously, lead to chute service life shorter.Problem above causes Iron Ore Powder to be leaked into air stove from weld seam, big in air stove
Amount piles up mixed material, or even hot-blast stove gas burner is buried, and has a strong impact on the production operation of revolving drum drier.
Content of the invention
This utility model is directed to the deficiencies in the prior art, provides a kind of Novel chute of revolving drum dehydrator, can be effective
Avoid cell body steel pipe heat damage and inter deterioration.
This utility model is achieved by the following technical solution, and provides a kind of Novel chute of revolving drum dehydrator,
Including for steel-tube construction the first groove and be fixed in described first groove one end and for steel-tube construction the second groove, in described second groove
Surface is installed with Ceramic Lined Pipes Made, and the second groove outer surface is installed with breather and flame retardant coating, is installed with one end in described flame retardant coating
Connect the air inlet pipe of described breather, the described air inlet pipe other end is communicated with source of the gas, described Ceramic Lined Pipes Made is installed with connection
Breather and some blowpipes of ceramic-lined pipe orifice.Flame retardant coating avoids the second groove cell body to be directly subject to high-temperature baking, ceramic-lined
Pipe is avoided material and is directly worn and torn with cell body；In source of the gas, compressed gas are ceramic-lined by air inlet pipe, breather and blowpipe entrance
Pipe orifice, carries out purging and air-dries, it is to avoid material sticks at ceramic-lined inside pipe wall to material.
Preferably, described breather includes being fixedly arranged on the second groove outer surface and the coil pipe that is interconnected and connecting tube, disk
Pipe circumferentially arranges, connecting tube is axially disposed, and air inlet and point gas are more uniform.
Preferably, described flame retardant coating includes being fixedly arranged on pouring skeleton and pouring bone by described of described second groove outer surface
The refractory material LIFT of frame cladding, not only can be high temperature resistant, and increased the intensity of the second groove.
Preferably, the described skeleton that pours includes some anchor studs being fixedly arranged on described second groove outer surface, described anchoring
Nail is arranged according to mode of anyhow interlocking two-by-two, increases the intensity of skeleton and the absorbability to fire resisting LIFT.
As optimization, described flame retardant coating thickness is more than 50mm it is ensured that enough high temperature strength.
As optimization, be passed through gas in described blowpipe flows to the inclination of feeding stream direction, blowpipe axis and the second fluted shaft line
Angle is 10 °～30 °.
The beneficial effects of the utility model are：Using composite structural design, it is to avoid cell body is directly subject to flame, hot waste gas
High-temperature baking, solves the problems, such as temperature distortion, weld cracking, improves wearability, the use of chute is greatly improved
In the life-span, improve the equipment availability efficiency of revolving drum dehydrator；Utilize air flow cooling pipe, using air purging simultaneously
Compound prevents the compound with moisture to be bonded in ceramic-lined pipe internal surface.
