Description

Sealed tube furnace observation door with cleaning function

Technical Field

The utility model relates to the technical field of tubular heating furnace equipment, in particular to a sealed tubular furnace observation door with a cleaning function.

Background

At present, the observation door of current tubular heating furnace is the observation door of uncapping, at the in-process that inspection personnel patrols and examines tubular heating furnace, need open the observation door of tubular heating furnace, just can observe the flame state in the stove, when inspection personnel observes the flame state in the stove, the combustion space in the stove is with external direct intercommunication, because the flame radiation in the stove, inspection personnel has the risk of being scalded because of needing long-time observation easily, in addition, when opening the observation door, if furnace is in the malleation combustion state, there is the high temperature flue gas overflow in the tubular heating furnace, cause serious scald to inspection personnel easily.

Disclosure of Invention

The utility model aims to provide a sealed tube furnace observation door with a cleaning function, which can prevent a patrol inspector from being scalded when observing the flame state in a furnace.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides a sealed tubular furnace observation door of clean function in area, includes steel section bar frame and window form, the window form install in the steel section bar frame, still include clean air supply pipeline, clean air supply pipeline include main gas-supply pipe and a plurality of exhaust branch pipe, the one end intercommunication of exhaust branch pipe be in main gas-supply pipe on, the other end setting of exhaust branch pipe be in the inboard of window form, the window form be high temperature resistant glass.

Further, steel section bar frame include inside casing and outside casing, the medial surface of inside casing be equipped with the draw-in groove, the window body joint on the draw-in groove, the medial surface of inside casing be equipped with first screw, the surface of outside casing and be in the position of first screw on be equipped with the through-hole, the through-hole in be equipped with first bolt of first screw spiro union.

Further, a second screw hole is formed in the surface of the outer frame body, a second bolt is arranged in the second screw hole, and the end portion of the second bolt is propped against the window body.

The utility model has the beneficial effects that: the window body of the observation door adopts high-temperature-resistant glass, and is matched with the steel section frame to form the sealed observation door, so that an inspection worker can observe the flame state in the tubular heating furnace through the window body, and the risk of scalding the inspection worker when observing the flame state is effectively prevented; because tubular heating furnace during operation can produce the carbon deposition to glue and glue on the window body, consequently this observation door still installs clean air supply pipeline, inserts compressed air or nitrogen gas from main gas-supply pipe, then discharges from the exhaust branch pipe, realizes sweeping the effect of window body medial surface, so that glue the carbon deposition on the window body and obtain the clearance, guarantees the normal observation operation of inspection personnel.

Drawings

FIG. 1 is a schematic view of a sealed tube furnace door with cleaning function according to the present utility model.

Fig. 2 is a sectional view A-A in fig. 1.

Detailed Description

The technical solutions in the embodiments of the present utility model will be described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, a sealed tube furnace observation door with a cleaning function comprises a steel section frame 1 and a window body 2, wherein the window body 2 is installed in the steel section frame 1, the sealed tube furnace observation door further comprises a clean air source pipeline, the clean air source pipeline comprises a main air conveying pipe 3 and a plurality of exhaust branch pipes 4, one ends of the exhaust branch pipes 4 are communicated with the main air conveying pipe 3, the other ends of the exhaust branch pipes 4 are arranged on the inner side of the window body 2, and the window body 2 is made of high-temperature-resistant glass.

The window body 2 of the observation door adopts high-temperature-resistant glass, and is matched with the steel section frame 1 to form a sealed observation door, so that an inspector can observe the flame state in the tubular heating furnace through the window body 2, and the risk of scalding the inspector when observing the flame state is effectively prevented; because tubular heating furnace during operation can produce the carbon deposition to glue and glue on window form 2, consequently this observation door still installs clean air supply pipeline, inserts compressed air or nitrogen gas from main gas-supply pipe 3, then discharges from exhaust branch pipe 4, realizes sweeping the effect of window form 2 medial surface, so that glue the carbon deposition on window form 2 and get the clearance, guarantees the normal observation operation of inspection personnel.

The steel section frame 1 comprises an inner frame body 5 and an outer frame body 6, wherein a clamping groove 7 is formed in the inner side face of the inner frame body 5, the window body 2 is clamped on the clamping groove 7, a first screw hole 8 is formed in the inner side face of the inner frame body 5, a through hole 9 is formed in the surface of the outer frame body 6 and located in the position of the first screw hole 8, and a first bolt 10 screwed with the first screw hole 8 is arranged in the through hole 9. The combined design of the inner frame body 5 and the outer frame body 6 can facilitate the installation and replacement of the window body 2 so as to ensure the effective use of the observation door.

The surface of the outer frame 6 is provided with a second screw hole 11, a second bolt 12 is arranged in the second screw hole 11, and the end part of the second bolt 12 is propped against the window 2. The combined design of the second bolt 12 and the second screw hole 11 can effectively perform stable fixing function on the window body 2, and also enables the inner frame body 5, the outer frame body 6 and the window body 2 to be tightly attached, so that high-temperature smoke in the tubular heating furnace is prevented from being discharged.
