Description

Technical Field

[0001] The utility model relates to an outer cover device for an observation window of a heating furnace in an oil refinery, in particular to a magnetic absorption type heat insulation cover device for the observation window of the heating furnace in the oil refinery made of an aerogel material. Background Art

[0002] At present, the heating furnace is equipped with a fire door device with a glass observation window to facilitate observation of the combustion of the burner inside the heating furnace. Since the observation window is a hanging device, if the insulation material itself is not installed in place, or during long-term operation, when the personnel observe the heating status in the furnace, the observation window is repeatedly opened and closed, and the observation window and the frame are worn, the connection parts are loosened and shifted, which will cause the sealing between the observation window and the window frame to be poor and the gap is too large. Once the gap between the observation window and the window frame is too large, the insulation effect of the heating furnace observation window cover is reduced, which will cause the heat of the heating furnace to leak out, causing heat loss, affecting the thermal efficiency of the heating furnace and energy saving and emission reduction; due to the different sizes of heating furnaces, the fire door changes accordingly. Generally, the refinery is a large heating furnace, the observation window is correspondingly enlarged, the heating furnace has a large firepower, the temperature on the front of the observation window is high, and the cover and removal of the observation window cover are unsafe, which is easy to scald the operator; In view of the above reasons, a magnetic heat insulation cover device for the observation window of the refinery heating furnace made of aerogel material is proposed. Utility Model Content

[0003] The purpose of the utility model is to overcome the problem that the observation window of the heating furnace door is set and hung on the outside of the observation window. The thermal insulation performance of the observation window itself may be due to the construction of the thermal insulation material and the use time, resulting in some heat leakage due to poor sealing, or in the long-term production process, the observation window switch is repeatedly worn, loosened, and shifted, resulting in poor sealing between the observation window and the frame and excessive gaps. Once the gap is too large, the thermal insulation effect of the heating furnace observation window is reduced, resulting in heat loss, affecting the thermal efficiency of the heating furnace and energy saving and emission reduction; generally, the refinery is a large-scale heating furnace, the temperature on the front of the observation window is relatively high, and the covering and removal operations of the observation window cover are unsafe, which is easy to scald the operator; through reasonable design, a magnetic absorption heat insulation cover device for the observation window of the refinery heating furnace made of aerogel material is provided; the utility model is fixed at the position of the heating furnace fire viewing window by the magnetic absorption heat insulation cover device, and the heating furnace fire viewing window is completely covered. A pair of operating handles are symmetrically arranged on both sides of the observation window magnetic insulation cover. When the observation window magnetic insulation cover needs to be covered or removed, two operators operate a pair of operating handles on both sides of the observation window magnetic insulation cover to cover or remove the cover, which can avoid the high temperature on the front of the observation window and ensure the safety of the operators; the heating furnace observation window outer cover is fixed by the corner magnets of the cover edge and the middle magnets of the cover edge to the outer wall of the heating furnace, and the heating furnace observation window outer cover is installed more firmly, and the heating furnace observation window outer cover is stably combined with the heating furnace door and firmly sealed; the utility model adopts aerogel material to reduce the overall weight of the insulation cover and is easy to install and remove. In addition, the heating furnace observation window outer cover is loaded and unloaded by the operating handles on both sides, which is stable and simple to operate, saves energy and reduces consumption, and improves the insulation effect and production efficiency of the heating furnace observation window outer cover.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a magnetic heat insulation cover device for an observation window of a heating furnace in an oil refinery made of aerogel material, which is composed of: a heat insulation outer cover of a heating furnace, a magnetic cover edge, magnets at corners of the cover edge, a magnet in the middle of the cover edge, an operating handle, and a heat insulation cover cavity; the magnetic cover edge is set in a rectangular shape, and magnets at corners of the magnetic cover edge are inlaid at four corners of the edge, and magnets in the middle of the edge of the magnetic cover edge are inlaid; a heat insulation cover cavity is reserved in the middle of the magnetic cover edge, a heat insulation outer cover of a heating furnace is set outside the heat insulation cover cavity, and the inner side of the heat insulation cover cavity corresponds to the observation window of the heating furnace door; the heat insulation outer cover of the heating furnace and the magnetic cover edge are set as an integrated aerogel material;

[0005] A pair of operating handles are symmetrically arranged on both sides of the outer side of the magnetic cover.

[0006] Beneficial effects: The utility model is fixed at the location of the heating furnace fire viewing window through a magnetically-absorbed heat-insulating outer cover device, and completely covers the heating furnace fire viewing window. The heating furnace observation window outer cover is fixed by the corner magnets of the cover edge and the middle magnets of the cover edge of the magnetically-absorbed cover edge adsorbing the outer wall of the heating furnace. The heating furnace observation window outer cover is installed more firmly, and the heating furnace observation window outer cover is stably combined with the heating furnace door and firmly sealed. The utility model adopts aerogel material to reduce the overall weight of the heat-insulating cover, and is easy to install and remove. In addition, the heating furnace observation window outer cover is loaded and unloaded through the operating handles on both sides, which is stable and simple to operate, saves energy and reduces consumption, and improves the heat insulation effect and production efficiency of the heating furnace observation window outer cover.
