Description

With the potent heat insulation laborsaving manhole door of energy-saving observation door
Technical field
The present invention relates to a kind of manhole door, particularly a kind of heating furnace manhole door.Belong to energy-saving equipment technical field.
Background technology
Manhole door is an important component part of industrial heating furnace, manhole door is arranged on the furnace wall of heating furnace, it is the device that maintainer passes in and out heating furnace, manhole door not only will make people come in and go out safely, and the isolation of internal environment and external environment condition in heating furnace operation will be ensured, guarantee that high-temperature flue gas does not leak, therefore its heat insulating ability and sealing directly affect the thermal efficiency of heating furnace.
Conventional manhole door has two kinds:
Self-supporting hinge is not with between the first doorframe and gate seat, each self-separation, bolted is used at ordinary times between doorframe and gate seat, when personnel need enter, first sending bolt to be pulled down by door closure looks for place to lay again, because door closure is heavier, workman constructs cumbersome, wastes time and energy and easily damages in installation course.
The second is band self-supporting rotary open type manhole door, general point two classes: the first kind is used in the not high place of furnace temperature (≤200 DEG C), as heating furnace convection section, is generally arranged in door closure by lining thermal insulation layer, and door closure thickness general control is in 60mm; Equations of The Second Kind is used in high-temperature area (≤1000 DEG C), as heating furnace radiant section.
There is following problem in conventional rotary open type manhole door:
1) temperature due to manhole door installation site (heating furnace radiant section) is very high, very thick (general more than 250mm) that thermal insulation layer must do, and conventional rotary open type manhole door must make corner cut skiving to avoid manhole door unlatching anglec of rotation ability smooth opening to thermal insulation layer, thermal insulation layer is thicker, corner cut skiving the more, causes this serious overtemperature in structure manhole door local.
2) for 1) in rotary open type manhole door, also have and thermal insulation layer module be independently arranged in manhole doorframe and be separated with door closure, though solve thermal insulation layer corner cut skiving problem, but during each heating furnace maintenance, all artificially must remove thermal insulation layer module after opening manhole door closure and lay, personnel just can enter, and bothersome effort and removing in installation course is easily damaged.
3) conventional rotary open type manhole door is a seal structures, when heating furnace runs, high-temperature flue gas is easy to overflow from the gap between manhole door and manhole doorframe, thus have the conventional rotary open type manhole door of potential safety hazard due to power transmission shaft position bearing is not set, general unlatching compares effort.
4) existing manhole door and observation door are independently two devices, open heat insulating ability and sealing bull point hidden danger that a door means heating furnace more.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of manhole door, this manhole door is provided with observation door, the enabling direction of this manhole door is perpendicular to furnace wall simultaneously, therefore manhole door closure medial septal thermosphere does not need corner cut skiving, ensure that heat insulating ability and the sealing of heating furnace, coordinates door opener, workman is made to open the door conveniently, time saving and energy saving.
The object of the present invention is achieved like this:

Detailed description of the invention
See Fig. 1-3, the present invention relates to a kind of potent heat insulation laborsaving manhole door with energy-saving observation door, it comprises manhole doorframe 1, manhole door closure 2, door opener and observation door 6, described manhole doorframe 1 is arranged on the outer wall of heating furnace, manhole door closure 2 top is provided with the opening 9 coordinated with observation door 6, manhole door closure 2 bottom is provided with door opener, described door opener comprises the first axle 5, first connecting plate 7, second connecting plate 8, 4th axle 10 and the 5th axle 11, 4th axle 10 is arranged on manhole door closure 2, one end of described first connecting plate 7 is connected with the 4th axle 10, the other end is connected with the first axle 5, one end of described second connecting plate 8 is connected with the first axle 5, the other end is connected with the 5th axle 11, described 5th axle 11 is fixed on manhole doorframe 1.
See Fig. 4-6, described observation door 6 comprises hold down gag 6.1, gate seat 6.2, observation door lid 6.4, drive link 6.5, second axle 6.6, 3rd axle 6.7, 3rd connecting plate 6.8 and handle 6.9, be fixedly connected with manhole door closure 2 outside described gate seat 6.2, visor 6.3 is provided with inside gate seat 6.2, during observation door closed condition, observation door lid 6.4 and gate seat 6.2 compress fits, the second thermal insulation layer 6.11 inside observation door lid 6.4 is positioned at gate seat 6.2, described handle 6.9 is arranged at the outer wall of observation door lid 6.4, described hold down gag 6.1 one end and gate seat 6.2 are fixed, the other end coordinates with observation door lid 6.4, observation door lid 6.4 is played to the effect of compression, described second axle 6.6 is fixed on the crossette 6.10 of gate seat 6.2, described drive link 6.5 has two and its one end is connected with the vertical both sides of observation door lid 6.4 respectively, the other end of drive link 6.5 is connected with the 3rd axle 6.7, one end of described 3rd connecting plate 6.8 is connected with the 3rd axle 6.7, the other end is connected with the second axle 6.6.
Operation principle: manhole door closure 2 is consistent with the unfolding mode of observation door lid 6.4, for observation door lid 6.4, see Fig. 7, first hold down gag 6.1 is opened, the opening direction of observation door lid 6.4 perpendicular to furnace wall, observation door lid 6.4 along the outside moving linearly in direction perpendicular to furnace wall, after pull-out, observation door lid 6.4 does circular motion around the 3rd axle 6.7, and now observation door lid 6.4 is opened completely.
The unfolding mode of manhole door closure 2 in like manner, the opening direction of manhole door closure 2 equally perpendicular to furnace wall, manhole door closure 2 along the outside moving linearly in direction perpendicular to furnace wall, after pull-out, manhole door closure 2 does circular motion around the first axle 5, and now manhole door closure 2 is opened completely.
Because first manhole door closure 2 does rectilinear motion, therefore the first thermal insulation layer 12 inside manhole door closure 2 does not need corner cut skiving, manhole doorframe 1 has twice to fit tightly sealing surface with the joint of manhole door closure 2, when heating furnace runs, high-temperature flue gas not easily overflows from the gap between manhole door and manhole doorframe, ensure that heat insulating ability and the sealing of manhole door, ensure that the security of production, coordinate door opener simultaneously, smooth and time saving and energy saving when manhole door closure 2 is opened.
The present invention arranges observation door on manhole door, both is integrated, and further ensures heat insulating ability and the sealing of heating furnace.
In figure, how the first thermal insulation layer 12 of observation door lid 6.4 has still done corner cut at a glance, and designer has considered that the thickness of the first thermal insulation layer 12 is enough to ensure effect of heat insulation, does the design of this corner cut only for attractive in appearance, be independent of each other with effect of heat insulation and unfolding mode in figure.Because observation door uses relatively more frequent, observation door is when opening, and can prevent heating furnace furnace flame from causing the problem of licking outside flame due to pressure reduction impact, for ensureing the personal safety of operating personnel, designer arranges visor 6.3 inside gate seat 6.2.
