Description
Technical field
The invention belongs to incineration of waste technical fields, specifically disclose a kind of rotary structure.
Background technique
As people's living standard improves, article used in life is more and more, and the speed that article updates is accelerated, life
In many unused articles such as electronic product, battery be taken as hazardous waste to handle, hazardous waste, which is packed together, not only to be accounted for
With biggish soil, moreover it is possible to pollute environment, increasing hazardous waste is made troubles to people's lives environment.
The mode for handling waste is usually to fill and burn, and during handling waste by the way of burning, can use burning
The waste heat of generation is generated electricity, is warmed oneself.It in incinerating waste material, generally requires and uses rotary kiln, when using rotary kiln incineration waste
Will appear following problem: waste is easy accumulation in rotary kiln, causes incineration of waste insufficient in this way, incineration of waste is insufficient
It is easy to produce more toxic and harmful gas, seriously pollutes air；Residue is deposited in rotary kiln bottom and cannot clear up in time, influences
Subsequent incineration of waste.
Summary of the invention
The purpose of the present invention is to provide a kind of rotary structure, being deposited in rotary kiln bottom excessively to solve residue influences
The problem of subsequent incineration of waste.
In order to achieve the above object, base case of the invention are as follows: rotary structure, including support frame, motor and cylinder,
Described cylinder one end is equipped with kiln head cover, and the other end of the cylinder is equipped with kiln hood, and cylinder rotates close with kiln head cover, kiln hood
Envelope connection, the side wall of the kiln head cover are equipped with the burning pipe for incinerating waste material, and the lower part of the kiln head cover is equipped with slag notch,
The kiln hood is equipped with feeding tube, and one end that the cylinder is located at kiln head cover is lower than the other end, on the cylinder inboard wall successively
Equipped with thermal insulation layer and flame retardant coating, the thermal insulation layer with a thickness of 65-75mm, the flame retardant coating with a thickness of 290-310mm, it is described
Support frame two sides are equipped with the support roller of face, and the support roller and support frame are rotatablely connected, and are additionally provided with gear on support frame as described above, institute
Cylinder body outer wall is stated equipped with belt wheel and outer gear ring, the belt wheel and support roller are against the outer gear ring is engaged with gear；The motor
The rotation of sliding tooth wheel.
The working principle of this base case is: using before this rotary kiln incineration waste, starting motor, and controls burning pipe
Flame, motor rotation driven gear rotation, drives outer gear ring and barrel body rotation when gear rotates；Waste is launched by feeding tube
Into cylinder, due to the inclined arrangement of cylinder, cylinder waste in rotation is mobile to kiln head cover side, burns pipe flame
Waste is burned in cylinder；The lime-ash generated after incinerating waste material drops into kiln head cover, and lime-ash can be discharged by kiln head cover.
The beneficial effect of this base case is:
(1) it studies for a long period of time discovery through applicant, sets 65-75mm for the thickness of thermal insulation layer, the thickness of flame retardant coating is set
When being set between 290-310mm, cylinder of rotary kiln external skin temperatures avoid the low temperature and height of hydrogen chloride gas at 240 DEG C or so
Warm corrosion region, extend cylinder uses the time；Meanwhile flame retardant coating and thermal insulation layer can play insulation effect, reduce in cylinder
The loss of heat can make the intracorporal waste full combustion of cylinder；
(2) cylinder is obliquely installed, during barrel body rotation, the intracorporal waste of cylinder and lime-ash can be from trend kiln head covers
Side is mobile, realizes self-skimming in the case where not needing to remove the gred structure by other.
Further, the thermal insulation layer is clay brick, and the flame retardant coating is chrome corundum brick.Chrome corundum brick has preferable high temperature resistant
Property, corrosion resistance, wearability etc., extend the service life of flame retardant coating.
Further, the side wall in the kiln head cover is equipped with the casing of rotation connection, and the burning pipe is located in casing, institute
It states one end that cylinder is located in kiln head cover and is distributed along the circumference with transverse slat, form groove between two neighboring transverse slat, in described sleeve pipe
It is fixedly connected with cam, the cam and the position of groove face are equipped with mandril, and the mandril protrudes into groove, the mandril
Gap is equipped between transverse slat.When the cylinder rotates, cylinder band motion plate rotates, and transverse slat rotation drives mandril rotation, due to top
Between bar and transverse slat be equipped with gap, therefore, when lime-ash is moved on transverse slat and mandril out of cylinder, the lesser lime-ash of particle from
It is fallen between gap, the biggish lime-ash of particle occurs to be crushed under the squeezing action of transverse slat and mandril, can prevent in lime-ash in this way
Larger particles accumulated in kiln head cover.
Further, the kiln head cover inner wall lower is hinged with the baffle for blocking slag notch, institute far from the side of cylinder
It states and is equipped with torsional spring between baffle and kiln head cover, the kiln head cover is located at the position above baffle and is equipped with lantern ring, on the baffle
Equipped with sliding slot, be slidably connected push rod in the sliding slot, and the top of the push rod passes through lantern ring, and the push rod upper end is equipped with push plate.
Band motion plate rotates when barrel body rotation, and mandril and cam is driven to rotate when transverse slat rotates, and cam rotation pushes on push plate and push rod
Lower movement, when push rod moves down, baffle opens slag notch, and the lime-ash in kiln head cover is discharged by slag notch, meanwhile, it is empty
Gas is added into cylinder, and intermittent tonifying Qi can not only make the intracorporal waste full combustion of cylinder, moreover it is possible to avoid crossing ambassador because of air inflow
The intracorporal thermal loss of furnace is more, ensure that waste can be sufficiently burned.
Further, the cylinder and the angle of horizontal direction are 1.6-1.8 °, and the revolving speed of the cylinder is 0.01-1.1r/
min.Cylinder can have preferable stirring effect to the intracorporal waste of cylinder, ensure that waste full combustion, together between this revolving speed
When be able to maintain speed of slagging tap more stable in cylinder, make rotary kiln stable operation；By the way that the revolving speed of cylinder is arranged, cylinder can be enable
The ulking thickness of residue has higher temperature in 50mm or so when ensure that trash burning.
