Abstract

The utility model discloses a light boiler uptake belongs to boiler technical field. This smoke box includes the smoke box body and smoke box door, the smoke box door certain thickness has, circumference is provided with the plane on smoke box door opening inside wall, the plane lies in within the smoke box door terminal surface, be provided with first sealing layer between the terminal surface in plane and smoke box door, it is gapped between smoke box door and the smoke box panel, the edge cover was in smoke box panel scope smoke box door week, be provided with the sealed lining of second in the clearance between smoke box door and smoke box panel, it has fire -resistant heat preservation lining to fill between smoke box door medial surface and the outside terminal surface, it has fire -resistant heat preservation to fill in the smoke box body. The double -deck seal structure of this smoke box adoption can prevent the flue gas more than 60% before getting into the smoke box door in theory, along with the reduction of exhaust gas volumn, follows to a great extent and has reduced the possibility that leads to smoke box surface production high temperature, so this kind of structure can make the more lightweight of design of smoke box door.

Description

A kind of lightweight smoke box

Technical field

The utility model relates to a kind of smoke box, in particular to a kind of lightweight smoke box, belongs to boiler technology field.

Background technology

High-temperature flue gas is collected by the main effect of smoke box exactly, and forces flue gas to turn to, and promotes flow of flue gas in the pyrotechnics pipe of next group backhaul. Therefore, the sealing property of smoke box door and smoke box body is required higher, and smoke box heat-insulating property is also had requirement. At present, generally there is the higher phenomenon of smoke box surface temperature in domestic pan shell type fuel vapor boiler, sometimes this kind of phenomenon also can compare seriously, and smoke box surface can with obvious burning phenomenon, when people near time will produce scorching hot sensation, there is certain potential safety hazard. On the other hand, the generation of high temperature will cause the work efficiency drop of equipment and system thereof, increases unnecessary running cost, causes waste. Boiler is in actual motion, and smoke box inside needs the high-temperature flue gas bearing 400 DEG C��600 DEG C to wash away, if the sealing property of smoke box is bad, will directly affect the work-ing life of boiler, even causes boiler normally not run. If smoke box heat preservation and insulation is bad, smoke box hull-skin temperature will being caused too high, heat lost by radiation increases, and reduces the thermo-efficiency of boiler, and scald accident may occur. Time serious with obvious burning phenomenon, can there is certain potential safety hazard in smoke box surface. The heat lost by radiation brought due to high temperature increases, and also result in the waste of fuel energy. On the other hand, owing to smoke box door weight is big, welded type hinge strength is inadequate, easily produces distortion under the action of gravity of smoke box door. And smoke box door is heavier, open and close comparatively inconvenience. In order to solve above practical problems, boiler applications needs the smoke box designing a kind of lightweight, sealing thermal insulation performance is good.

Summary of the invention

The purpose of this utility model is to overcome in existing smoke box the above-mentioned technical problem existed, it is provided that a kind of lightweight smoke box.

For realizing the purpose of this utility model, have employed following technical scheme: a kind of lightweight smoke box, comprise smoke box body and smoke box door, described smoke box door has certain thickness, on smoke box door opening inner side-wall, circumference is provided with plane, within plane is positioned at smoke box door inner face, the first sealing ply it is provided with between plane and smoke box door inner face, gap is had between smoke box door and smoke box panel, smoke box door periphery covers in smoke box panel scope, the 2nd sealing lining it is provided with in gap between smoke box door and smoke box panel, fire resistant heat preserving lining it is filled with between smoke box door inner side end and end face outside, smoke box body is filled with refractory insulating layer, further, the first described sealing ply is: smoke box door flange connections inner circumferential is provided with plane, plane arranges a circle sealing groove, asbestos twine it is filled with in sealing groove, smoke box door is provided with the circle of with sealing groove mating shapes protruding, asbestos twine in protruding top tight sealing groove during closedown, smoke box door and smoke box body are filled with ceramic fiber fire resistant heat preserving lining, further, smoke box door is hinged on smoke box panel by hinged part, described hinged part is crotch, smoke box door is hinged on two bifurcateds of crotch, the butt of crotch is hinged on smoke box panel.

In the utility model, the first layer sealed structure can block high-temperature flue gas to the impact of second layer sealing material, blocks flue gas heat and outwards conducts, and this kind of dual seal smoke box has good heat-proof quality and sealing property. Adopt double-layer sealing structure can be stoped before entering smoke box door by the flue gas of more than 60% in theory, along with the minimizing of exhaust gas volumn, from reducing the possibility causing smoke box surface to produce high temperature to a great extent, so this kind of structure can make the design more lightweight of smoke box door. The design adopts a kind of simple, light and durable novel smoke box structure, manufacturing process simple possible, and safe reliability is also synchronously guaranteed, and to existing smoke box structure is one and well optimizes. Novel light smoke box, taking comparatively outstanding heat insulation effect, good processing characteristics and lighter quality as technology starting point, reduces the heat lost by radiation on smoke box surface, decreases the consumption of gas energy, serves energy-conservation effect. The design of twin shaft smoke box door tumbler in addition the choosing of light heat insulation material so that smoke box door is opened very convenient, improves the operability of smoke box to a great extent, and maintenance and maintenance work to the equipment later stage bring great convenience.
