Abstract
The utility model discloses a nozzle brick fire-guard cooler for one-piece formed components. The central part of the cooling body is a hollow cooling cavity. An air inlet pipe, an air outlet pipe are placed on the dummy club in the front face of the cooling body. The air inlet pipe and outlet pipe communicate with the air passage of the cooling cavity. A fire hole is opened in the center of the front face of the cooling body and a through-hole is provided in the center of the fire hole. An oblique cone is provided on the outskirt of the through-hole and internal wall of the fire hole. Gas film holes are evenly distributed on the oblique cone. An inward groove is provided between the circular internal dummy club and the end face. Through the circulation of heated air inside the inlet pipe, the outlet pipe and the oil gun pulverized gas, the cooler of the present utility model further improves the atomization quality of fuel oil, increases the combustion efficiency of fuel oil. An oblique cone designed inside the fire hole and the gas film holes evenly distributed on the oblique cone can break down the reversed-flow region formed by working of the oil gun and thus reduces the coking problem on the back surface of the cooler.
Description
Technical field
The utility model relates to a kind of cooling device that is applicable to Industrial Stoves oil gun burner brick, more particularly says, is meant that a kind of nozzle brick keeps off fiery cooler.
Background technology
Nozzle brick is a general industry kiln oil gun burner brick, and environment temperature is up to more than 1500 ℃ in the brick, and generally, the aperture of nozzle brick is big than the oil gun shower nozzle, and behind the work certain hour, owing to the reason of ablating can cause the aperture further to strengthen.So, when oil gun is worked on the one hand,, cause the interior thermal efficiency of kiln to reduce because the effect cool ambient air of jet is introduced in (suction) kiln by a large amount of; On the other hand, when the oil gun commutation is not worked, injection kinetic energy and furnace pressure effect that the work of opposite side oil gun produces, the nozzle brick mouth loses heat energy outward.In addition, oil gun operating ambient temperature height causes adverse circumstances to operating personnel.
In order to improve the thermal efficiency, reduce heat-energy losses and improve operating personnel's working environment, the inventor has designed a kind of thermal efficiency that can improve effectively and has stopped that cold air enters in the kiln, and heat energy is to external radiation and reduce heat-energy losses, and the nozzle brick that reduces the oil gun operating ambient temperature keeps off fiery cooler.
Summary of the invention
The purpose of this utility model provides a kind of nozzle brick and keeps off fiery cooler, it is the integrally casting profiled member that this nozzle brick keeps off fiery cooler, carry out the air-flow exchange by air inlet pipe, escape pipe and cooling chamber and reach the purpose that the cooling jet brick keeps off fiery cooler, its reasonable in design, compactness, simple are easy to processing and fabricating.
The utility model is that a kind of nozzle brick keeps off fiery cooler, and its member that is formed in one is hollow cooling chamber in the centre of cooling body; The boss in cooling body front is provided with air inlet pipe, escape pipe, air inlet pipe and escape pipe and the conducting of cooling chamber gas circuit; The cooling body front center is provided with fire jetting hole, and the center of fire jetting hole is a through hole, and through hole outer rim and fire jetting hole inwall are provided with a scalene cone, evenly is furnished with air film hole on the scalene cone; The cooling body back side is provided with annular outer platform, annular inner convex platform, end face, is outer groove between annular outer platform and the annular inner convex platform, is inner groovy between annular inner convex platform and the end face.
The advantage that the utility model nozzle brick keeps off fiery cooler is: (1) can stop in the kiln heat-energy losses outward, thereby improves the thermal efficiency in the kiln; (2) can stop cool ambient air by in the oil gun work jet introducing kiln, thereby improve the thermal efficiency in the kiln; (3) reduced oil gun operating personnel's environment temperature; (4) by the circulation of cooling chamber 12, air inlet pipe 1, escape pipe 2 and oil gun atomization gas, make heated air carry out one and go on foot the atomization quality that improves fuel oil, improved combustion efficiency of fuel oil; (5) be designed to scalene cone 5 in the fire jetting hole 7, and uniform air film hole 6 can be broken the recirculating zone that oil gun work forms on scalene cone 5, thereby alleviate cooler back side fuel oil coking defective.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also shown in the accompanying drawing, it is a kind of one-body molded member that nozzle brick of the present utility model keeps off fiery cooler, and the centre of its cooling body 3 is a hollow cooling chamber 12 (as shown in Figure 3); The boss 4 in cooling body 3 fronts is provided with air inlet pipe 1, escape pipe 2, air inlet pipe 1 and escape pipe 2 and cooling chamber 12 gas circuit conductings; Cooling body 3 front center are provided with fire jetting hole 7 (fire jetting hole 7 apertures and Industrial Stoves oil gun output aperture are adaptive), the center of fire jetting hole 7 is through holes 14, through hole 14 outer rims and fire jetting hole 7 inwalls are provided with a scalene cone 5, evenly are furnished with air film hole 6 (as shown in Figure 1) on the scalene cone 5; Cooling body 3 back sides are provided with annular outer platform 13, annular inner convex platform 10, end face 8 link of the atomization gas output port of Industrial Stoves oil gun (promptly with), being outer groove 9 between annular outer platform 13 and the annular inner convex platform 10, is inner groovy 11 (as shown in Figure 2) between annular inner convex platform 10 and the end face 8.
In the utility model, the hollow cooling chamber 12 in cooling body 3 centres and the air inlet pipe 1 in cooling body 3 fronts and the gas circuit conducting of escape pipe 2, realized circulating of inside and outside air-flow, heated air can import oil gun when reaching the ablated problem of this cooler of cooling, as the atomizing air of oil gun, thus the atomization quality of raising fuel oil.Uniform air film hole 6 is designed to conical through-hole or straight shape through hole on the scalene cone 5, solved the reflux problem that the oil gun atomizing air produces when fire jetting hole 7 enters, when having stoped the oil gun commutation not worked, injection kinetic energy and furnace pressure effect that the opposite side oil gun works on and produces, the nozzle brick mouth loses heat energy outward; Simultaneously, the air film hole 6 of cooling body 3 back side end faces 8 helps alleviating the conduction of heat.The inner groovy 11 at cooling body 3 back sides and the structural design of outer groove 9 have solved nozzle brick effectively and have kept off the conducting effect of fiery cooler heat.
In the utility model, also can evenly arrange louvre on the sidewall of annular outer platform 13, the design of louvre helps the heat dissipation problem of industrial furnace when ablating.
