Abstract
The utility model relates to a vertical refrigerator for cement rotary kilns, composed of a vertical refrigerator cylinder, an eccentric conical grate, a hollow drive shaft, a cold blast pipeline, a drive mechanism and a discharging pipe, wherein, the vertical refrigerator cylinder is a cylinder, the upper end is provided with a choke, and the lower end forms a cone shape; the upper part in the cylinder is lined with a fireproofing material inner lining, and the lower end is lined with a castiron inner lining; so, the quality of cement can be raised, heat released from high-temperature clinkers can be effectively utilized to preheat the secondary air, and the full line thermal efficiency is improved; the utility model has the advantages of simple structure and low investment and is especially suitable for medium and small sized rotary kiln with the clinker output of less than 40 tons/hour.
Description
The utility model is the vertical cooler that a kind of cement rotary kiln cooling down high-temperature grog is used, and is a kind of cement industry plant equipment.
The high temperature chamotte of in rotary kiln, calcining, essential cooling fast behind the kiln discharge, to prevent the crystal transfer of dicalcium silicate, the decomposition of tricalcium silicate and magnesia crystallization are that periclase influences stability of cement, in addition, chilling can also improve the grindability of grog.So the grog cooling device is extremely important.Current domestic used cooler is many, and monotubular and comb formula are several.
See that with monotubular and grate cooler that present domestic consumption is maximum exist subject matter to have: 1. weight of equipment is big, investment is expensive, and 2, occupation area of equipment is big, 3, power consumption is big, 4, the grate cooler dust is big, running rate is low.
Task of the present utility model is the vertical cooler of a kind of rotary kiln that designs according to the principle of cement in vertical kiln lower eccentric taper discharging fire grate at the cooling problem of above-mentioned cement rotary kiln kiln discharge grog, make dynamic cooling air all carry out countercurrent heat exchange by the bed of material, high temperature chamotte can evenly be cooled off fast, very thick because of cooling air again by the grog layer, the secondary wind dust-laden of using cooler is few, the wind-warm syndrome height can supply the combustion-supporting usefulness of rotary kiln, can improve the thermal efficiency completely.
Structure of the present utility model can be referring to Fig. 1, and it is mainly by cooler cylindrical shell 7, eccentric taper discharging fire grate 10, and the Hollow Transmission Shafts blowing line 11 of holding concurrently, transmission mechanism 12, discharge duct 1 constitutes; The cooler cylindrical shell is that the upper end has reducing, and the lower end is the tube of cone, tube internal upper part lining refractories liner 8, and following end liner cast iron liner 9, cylindrical shell is fixedly mounted on the basis facing to cement rotary kiln high temperature chamotte discharge port 3; Eccentric taper discharging fire grate 10 is connected as a single entity with the Hollow Transmission Shafts of double blowing line, have the hole of blanking and ventilation usefulness and the tooth that particle is used on the eccentric taper discharging fire grate 10, connect cool air hose under the Hollow Transmission Shafts, and link to each other, connect vibration material envelope conveyer under the discharge duct with air blast.Hollow Transmission Shafts 11 is being with by transmission mechanism 12 and is being rotated, cold wind is sent in hole by the taper fire grate in cooler, when eccentric taper fire grate rotates, gap on every side constantly changes, the bulk grog can be squeezed broken dropping in the discharge duct by its particle tooth, by vibration material envelope conveyer, will cool off grog and deliver in the clinker warehouse.The material degree of filling is by measuring instrument 6 observing and controlling in the cooler inner cylinder.
Embodiment:
The grog that burns till in the rotary kiln 5 falls into cooler by discharge port 3, carry out heat exchange with the cold wind that advances from following cool air hose drum, clinker cools off gradually, the cold wind that comes up from below is heated to be the grog discharge port 3 of hot blast by rotary kiln and enters rotary kiln 5 as combustion air, the grog that is cooled drops to eccentric taper fire grate gradually, the bulk grog constantly done eccentric motion fire grate fragmentation, by taper fire grate and barrel gap, and the hole on the fire grate falls to drop to discharge duct, transported by vibration material envelope conveyer.
The utility model is applicable to that grog output is the middle-size and small-size rotary kiln employing below 40 tons/hour.
Advantage of the present utility model and effect:
1, cooling effectiveness height, dynamically cold air all carries out countercurrent heat exchange by the bed of material, makes equably fast cooling of high temperature chamotte, and the grog chilling guarantees the raising of cement quality.
2. vertical cooler shell stationary fixing, the barrel heat-insulation and heat-preservation, reverse heat exchange, cold air does not have short circuit, can obtain higher temperature, and the controllable dustiness of air quantity secondary wind seldom is combustion-supporting for rotary kiln, can improve the thermal efficiency completely.
3, equipment simple, economize with material, be convenient to make and install, the running rate height, maintenance task is few, takes up an area of less, reduced investment, goes up this project investment and only reach 1/5 of monotubular and grate cooler.
Description of drawings:
Accompanying drawing 1 is a cross-sectional view of the present utility model, numbers 1 among the figure, discharge duct, 2, forced the grog layer of cooling by cold wind, 3, rotary kiln high temperature chamotte discharge port, 4, grog in the kiln, 5, rotary kiln, 6, the level measuring and controlling instrument, 7, cooler cylindrical shell, 8, refractory lining, 9, the cast iron liner, 10, eccentric taper discharging fire grate, 11, the Hollow Transmission Shafts cold air duct of holding concurrently, 12, transmission mechanism.
