Abstract
An air-cooled hearth fire-viewing device comprising: the observation tube, the high-temperature glass, the sleeve, the compressed air interface and the discharge port; the sleeve is sleeved on the fire observation tube, the outer end of the sleeve is provided with a compressed air interface, a gap is arranged between the sleeve and the fire observation tube, and the side wall of the fire observation tube sleeved by the sleeve is provided with a through hole; high-temperature glass is fixed on the outer end face of the fire observation tube; the peeping cap is sleeved at the outer end of the peeping pipe, high-temperature glass is embedded at the top of the peeping cap, and a discharge port is arranged on the side wall of the peeping pipe close to the outer end. At ordinary times, the observation tube is cooled by blowing compressed air into the sleeve, and when observation is needed, the baffle device is opened and inward observation is carried out through high-temperature-resistant glass on the peeping cap.
Description
Technical Field
The utility model relates to an air-cooled furnace fire observation tube structure is installed at furnace afterbody or side for survey flame.
Background
The fire observation hole or the fire observation device of the hearth is a necessary flame observation hole of a boiler and is used for observing the flame combustion condition of the hearth of the boiler, the conventional fire observation hole consists of a steel pipe and high-temperature-resistant glass, the high-temperature-resistant glass is positioned on the outer end face of the steel pipe, and the steel pipe extends into the hearth and is separated by the high-temperature-resistant glass and a pipe hole of the steel pipe to observe the condition in the hearth of the boiler. When the temperature of the flue gas in the hearth of the boiler is too high, the temperature of the fire observation hole and the peripheral wall surface is over-temperature, and certain danger exists when the fire observation tube of the hearth is used.
And due to high temperature, the color of the paint around the steel pipe of the fire observation hole can also change, and the appearance of the boiler is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an air-cooled furnace sees fire hole structure is furnace and sees fire device is provided to above-mentioned prior art, installs at furnace afterbody or side, through blowing compressed air to seeing the fire downthehole, can effectively reduce the outside heat transfer of high temperature in the furnace, guarantees to see the outside normal atmospheric temperature that keeps of fire hole.
The utility model provides a technical scheme that above-mentioned problem adopted does: an air-cooled hearth fire-viewing device comprising: the observation tube, the high-temperature glass, the sleeve, the compressed air interface and the discharge port; the sleeve is sleeved on the fire observation tube, the outer end of the sleeve is provided with a compressed air interface, a gap is arranged between the sleeve and the fire observation tube, and the side wall of the fire observation tube sleeved by the sleeve is provided with a through hole; high-temperature glass is fixed on the outer end face of the fire observation tube; the peeping cap is sleeved at the outer end of the peeping pipe, high-temperature glass is embedded at the top of the peeping cap, and a discharge port is arranged on the side wall of the peeping pipe close to the outer end.
At ordinary times, the observation tube is cooled by blowing compressed air into the sleeve, and when observation is needed, the baffle device is opened and inward observation is carried out through high-temperature-resistant glass on the peeping cap.
Has the advantages that: compared with the prior art, the utility model has the advantages of: the utility model provides an air-cooled furnace fire observation hole, through to seeing the fire hole cover intraductal compressed air cooling observation pipe that blows, can effectively reduce the interior high temperature of furnace and outwards transmit heat, guarantee to see that the device outside keeps similar normal atmospheric temperature. Simple structure and convenient popularization and application.

FIG. 1 is a schematic structural view of an air-cooled hearth fire observation hole in the embodiment of the utility model;
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, an air-cooled type hearth fire observation hole structure in the embodiment includes: the observation tube comprises an observation tube 1, a sleeve 2, a compressed air interface 3, a peeping cap 4, high-temperature-resistant glass 5, a discharge port 6 and a baffle device 7. The sleeve is sleeved on the fire observation tube, a ring is arranged at the inner end of the sleeve, so that a gap is formed between the sleeve and the fire observation tube, a compressed air interface is arranged at the outer end of the sleeve, the sleeve is sleeved on the fire observation tube, the gap between the sleeve and the fire observation tube is a flow channel of compressed air, and a through hole is arranged on the side wall of the fire observation tube sleeved by the sleeve to allow the compressed air to flow to the fire observation tube and cool the fire observation tube; the fire observation tube is provided with a baffle device which is arranged in the fire observation tube from the outer end surface of the fire observation tube and blocks and protects the peeping cap and the high-temperature glass.
The operation principle of the air-cooled hearth fire observation hole structure is as follows: when the boiler is operated, compressed air is blown into the sleeve 2 through the compressed air interface 3 to cool the fire observation tube 1, and then the compressed air enters the hearth or is discharged outwards. The compressed air is blown into the sleeve to cool the observing tube, and when observation is required, the shutter device 7 is opened, the high temperature resistant glass 5 behind the observing cap 4 is used for observation, and the discharge port 6 can be opened to perform air discharge (compressed air) or water discharge when necessary.
The structure uses compressed air to cool the fire observation tube, so that the surface temperature of the outer part of the fire observation tube furnace is close to the normal temperature. It should be noted that the above-mentioned embodiment is only a preferred embodiment of the present invention, and any modification or improvement made by those skilled in the art based on the above-mentioned conception is within the protection scope of the present invention.
