Abstract
The utility model discloses a high-efficiency heat-insulation observation door which comprises a door frame and a door cover, wherein an observation hole is formed in the center portion of the door frame, the door frame includes a fixing frame and a groove heat-insulation block which is attached to an inner side wall of the fixing frame, the observation hole is formed in the center of the groove heat-insulation block, the door cover is provided with a convex heat-insulation block which can be inserted into the observation hole, and the convex heat-insulation block is in driving fit with the observation hole. The convex heat-insulation block on the door cover can be sealed tightly with the observation hole when the observation door cover is closed, so that the effects of being without air leakage, isolating from the furnace temperature, reducing heat loss, and improving heat efficiency of a heating furnace, are achieved. The temperature of the outer wall of the furnace is equal to room temperature. The high-efficiency heat-insulation observation door has the advantages of being low in manufacturing cost of heat-insulation block materials, simple in structure, quick to produce and convenient to maintain.
Description
Technical field
The utility model relates to a kind of observation door of heating furnace of petroleum chemical industry.
Background technology
In the petroleum chemical industry, the following problem of observation door ubiquity of heating furnace: poorly sealed, cause heater efficiency to descend; Observation door does not establish lining or the lining effect of heat insulation is poor, causes the observation door temperature high; Observation door at the scene in the manufacture process because manufacture difficulty is larger, cause observation door lining and observation door periphery heating furnace lining deviation large, outside wall temperature height around observation door and the observation door; Cost is higher.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of effectively insulating observation door is provided, makes its sealing and thermal insulation good.
In order to solve the problems of the technologies described above, the utility model comprises doorframe and door closure, the doorframe middle part is provided with peephole, described doorframe comprises fixed frame and the groove heat insulation of fitting with the fixed frame madial wall, peephole is arranged on groove heat insulation central authorities, described door closure be provided with can insert in the peephole and with the protruding heat insulation of peephole phase driving fit.
For the ease of being connected with the furnace wall, the outside of described fixed frame is fixed with installing plate, and installing plate is provided with for the bolt that connects the furnace wall.
For make the utility model not only fire resistance well but also structural strength high, described fixed frame, installing plate and door closure adopt steel, described groove heat insulation and protruding heat insulation adopt fire-resistant heat insulating material.
In order further to improve sealing, described peephole apertura lateralis section is the frustum hole, and described protruding heat insulation is the corresponding cone table of frustum hole section with peephole.
For the ease of folding, described doorframe and door closure are articulated and connected.
Firm in order to connect, be fixed with bearing pin on the described fixed frame, be connected with two connecting rods on the bearing pin, bearing pin and connecting rod are rotationally connected, and two connecting rods parallel, and two connecting rods are all fixed with door closure.
The beneficial effects of the utility model: when closing the observation door lid, protruding heat insulation on the door closure can seal closely with peephole, thereby reach the effect of not leaking out, completely cutting off fire box temperature, reduction heat-energy losses, improve thermal efficiency of heating furnace, so that the hearth outer wall temperature is identical with room temperature; Heat insulation fast material is cheap, simple in structure, makes quick, easy to maintenance.
