Description
Technical field
The utility model relates to a kind of cement rotary kiln field, especially a kind of rotary kiln baiting dustpan supporting plate case.
Background technique
Cement rotary kiln blanking support plate is used in cement rotary kiln kiln tail smoke-box, needs to utilize its length, width, thickness
Degree and performance support resistant to high temperature live to pour high-temperature flame-proof pouring material at an upper portion thereof, and realize the shape knot for forming guide scraper-trough conveyer
Raw material water conservancy diversion after the pyrolytic of preheater is entered in kiln to calcine by structure, important as cement production system
Heat-resisting steel part, has the function of guide in production run.
Blanking support plate makes after preheating, decomposing from preheater because it needs to support castable refractory using its structural strength
Raw material can through this guiding after be fed into mature calcined material in rotary kiln, so it is needed to have stronger structural strength；Such as its damage
The bad castable of support to its upper that will result directly in generates slump, enters kiln life after pyrolytic herein so that flowing through
Material cannot be guided in kiln and generate kiln tail material leakage, cause rotary kiln that can not operate and pollute the accident of environment.
Because blanking support plate uses position in rotary kiln, it is harsh to bear 1100 ~ 1200 degree of high temperature and alkali, sulphur, chlorine etc.
Atmosphere corrode, therefore it is required that it will have a preferable structural strength, damage is mostly scaling loss deformation, fracture.
Former blanking support plate is the strip supporting plate of width 260mm, long 750mm, thickness 25mm, and supporting plate seat is welded on kiln tail smoke-box branch
On fagging, the 70% of length is partially protruded into kiln.After being corroded by high temperature and subversive gas, so that supporting plate service life is shorter, one
As between 3 months to 1 year；Replacement all needs to stop kiln every time, and after internal temperature is dropped to room temperature, operator just can enter internal work
Industry first has to replace supporting plate again after destroying supporting plate top castable refractory；Therefore replacement can all give production run, fire resisting every time
Castable consumption, supporting plate spare unit etc. bring greater loss.
In addition, Chinese patent announces " a kind of rotary kiln baiting dustpan ", it is mainly characterized by, including rolled with stainless steel plate
Made of dustpan body and area and pour concrete area positioned at laying bricks for dustpan body, it is characterised in that:
(1) the heat-resisting steel panel vertical with dustpan body steel plate is connected in the dustpan body forward position of stainless steel coiled sheet,
(2) it lays bricks in dustpan body and is equipped with the steel partition vertical with dustpan body steel plate between area and pouring area,
(3) dustpan body in fire resisting concrete placings region is fixed with latticed gusset.
In view of the above-mentioned problems, the utility model devises a kind of rotary kiln baiting dustpan supporting plate case, by original single panel type knot
Structure has been changed to hollow double-layer structure, can effectively promote the structural strength of supporting plate, by it is original without cooling vulnerable to thermal deformation, it is easy to damage right
The influence factor of service life has carried out Curve guide impeller, is changed to supporting plate case into hollow structure, cavity is interior to pass through air cooled shape
Formula reinforces cooling inside supporting plate case, the heat acted on supporting plate case is converted, and makes to be able to maintain after supporting plate is cooling good
Structural strength, create conditions to improve service life.
Summary of the invention
The purpose of the utility model is to provide a kind of structural strengths to improve supporting plate, promote the service life of supporting plate, drop
Low productive labor intensity devises a kind of rotary kiln baiting dustpan supporting plate case.
The utility model is realized using this method: a kind of rotary kiln baiting dustpan supporting plate case, is using supporting plate packing list
Body forms curved surface dustpan body, and curved surface dustpan body is connected to a fixed with kiln tail portion smoke-box pop-up panel seat, the weldering of smoke-box pop-up panel seat
It connects on supporting plate seat supports plate, physically there is castable refractory in curved surface dustpan, connected in curved surface dustpan body air inlet end
Cool wind box.Supporting plate plate case monomer structure is divided into base portion and preceding support two parts, and pedestal installation utilizes four heat-resistance high-strengths
Bolt is fixed on smoke-box pop-up panel seat, and preceding support is fixed after docking with slit between pedestal with bolt；It is normal every time only replacement by
The heavier preceding bearing of scaling loss, the lighter base portion of scaling loss can not have to replace every time, and only need to be by head when each replacement
The heat-resisting castable of bearing is pulled out bolt after removing and can be replaced before portion, therefore substantially saves replacing construction and fee of material
With.
The utility model has the beneficial effects that original dustpan supporting plate 1 year uses two to three sets, existing four Nian Zuo of novel supporting plate
Right use is a set of, and supporting plate fee of material can save about 160,000 yuan；Operating expenses and refractory casting are replaced every time after original supporting plate corrupted
Expect that Master Cost is 60,000 yuan, 4 years saving construction costs and refractory material expense are ten thousand yuan about more than 40；Because replacement supporting plate stops kiln to production
Influence loss do not give calculating in the case where, only the design, transformation of new supporting plate are just reached using the comprehensive benefit in a cycle
Nearly 600,000 yuan.Therefore deck internal cooling in hollow structure by air cooled form, will be reinforced, work using new design
It is converted with the heat on supporting plate, makes to be able to maintain good structural strength after supporting plate is cooling, to improve service life wound
Make condition.
