Description
Technical field
Cooling machine Anti-caking is assisted thrust unit, belongs to the cement manufacture plant field.
Background technology
Be accompanied by the progress of cement technology, the technology of undertaking the cooling machine of grog cooling task constantly develops, satisfying wet-process cement production from the eighties of last century early sixties is the birth that the main first generation " approaches bed of material cooling machine ", the exploitation and the technology maturation that adapt to the second generation " thick bed of material cooling machine " of new dry cement production technology development to the eighties, arrive the nineties initial stage in order further to save energy and reduce the cost and to adapt to the development of equipping maximization until late nineteen eighties, third generation TC type inflation deck-molding is imitated the cooling machine and is begun to come out, after third generation inflating beam grid formula cooler technology, a kind of cooler of new generation of reforming theory has fully appearred in the world.They have modularization, do not have to leak material, wearing and tearing less, row motion, transfer efficiency height, heat recovery efficiency height, running rate height, characteristics such as in light weight.No matter which for the cooling machine, all is to improve rate of heat exchange, reduce the leakage material, reduce wearing and tearing, avoiding working hard on the fault, do not having the careful cooling machine of considering windrow, the handling problem of ramming material.
Because the variation of crude fuel composition, the method for operating that varies with each individual, and the instability of system all can cause the high-temperature material stickiness to increase and form cooling machine windrow, ramming material.At cooling machine windrow, ramming material problem, no matter external, domestic, the one, adopt air bubble, though can promote material movement, reduce material and stop phenomenon.But because factors such as the air pressure of ejection air, tolerance, motion state often are difficult to clean out; In addition, the gas shock meeting of air bubble destroys the cold burden layer of grate plate face, and grate plate is exposed in the heat material, the destructions such as oxidation of aggravation grate plate.The 2nd, adopt giant, though can avoid windrow, ramming material, people's operation in person at the scene must be arranged, abnormal condition not only also can cause red-hot watering material feeding and grate plate ftractures because of quenching, and equipment is caused huge destruction, increases maintenance cost.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, easy to maintenance, can safety, the auxiliary thrust unit of cooling machine Anti-caking of windrow, ramming material in stable, the fast processing cooling machine.
The technical scheme that its technical problem that solves the utility model adopts is: this cooling machine Anti-caking is assisted thrust unit, it is characterized in that: comprise, frame, carrying roller, the box push pedal of step, connection activity jaw, oil cylinder, limitation travel switch, carrying roller is installed in above the frame, the box push pedal of step is installed on the carrying roller, oil cylinder is connected with the box push pedal of step by connection activity jaw, and oil cylinder is fixed on the frame by the oil cylinder fixture, and limitation travel switch is installed on the frame.
The box push pedal of step, form by preceding case and rear cabinet, preceding case is the work push pedal, be fixed on the rear box, the bottom is equipped with oil cylinder in the rear box, and the middle and upper part is provided with dividing plate in the rear box, be used for concrete perfusion or dose other weight, quantity is as the criterion with box weight before can balance, and its effect is to lean forward during the casing pusher before preventing, it is inner and burn and damage sealing device to slip into the cooling machine.
Operation principle: the auxiliary thrust unit of cooling machine Anti-caking mainly is grouped into by frame, push pedal, oil cylinder and electrical control division.Wherein the step case structure is adopted in push pedal, and first half is welded by heat-resisting steel sheet and plate, with high temperature erosion and the impact that adapts to material; Latter half is made stepped ramp type, and inside pours into waters material feeding, not only plays self-locking, anti-thrust plate because deadweight slips into the cooling machine at extreme position, and can the balance head weight.Oil cylinder is the transmission component of hydraulic test, is characterized in that thrust is big, automatic overload protection, possesses pooling feature simultaneously, operates steadily.Electrical control cubicles is sent instruction and is controlled cylinder action by Hydraulic Station, the back and forth movement of the flexible drive push pedal of oil cylinder, thereby reach safety, stable, handle and be deposited in the high-temperature material that coheres in the cooling machine fast.
The beneficial effect that the auxiliary thrust unit of the utility model cooling machine Anti-caking is had is:
1, this apparatus structure is simple, and is easy to operate, and safety, stable is effectively improved cooling machine front end windrow operating mode, has optimized system process, alleviates staff labor intensity, has solved cooling machine windrow, ramming material problem, guarantees that system condition is stable.
2, adopt this device can save air bubble, the giant that generally adopts at present, they mostly are imported product, and the maintenance, repair difficulty is big; Related accessory is special purpose parts, costs an arm and a leg, and delivery date is long.And the thrust unit of development adopts hydraulic power voluntarily, and all adopts homemade, and maintenance and repair is very convenient.
When 3, artificial or employing giant was cleared up ramming material, cooling machine spot check door was in open mode, and cold wind is scurried in a large number, influences thermal technology's balance in the kiln, made to descend about 30-50 ℃ into kiln secondary air temperature degree that system's coal consumption will increase 1.5-3.0t/h.After adopting this Anti-caking thrust unit, the cleaning ramming material is to carry out under airtight state fully, has saved a large amount of coal consumptions that increase because of leaking out.
4, reduce material reducing artificial or that adopt giant to clear up ramming material and moved, can protect personal safety simultaneously, significant to energy savings and protection environment, have good application value.
To the damage of refractory material and grate plate, effectively protect equipment when 5, this project implementation has been avoided adopting giant, prolonged their service life.
