Abstract
The invention relates to a protection device of a viewing lens inside a high-temperature heating furnace, in particular to a spiral air curtain cooling lens case of a high-temperature industrial television. The spiral air curtain cooling lens case of the high-temperature industrial television is provided with a case body, the center of the case body is provided with a through hole, and the periphery of the through hole of the case body is provided with an air inducing device which forms an air vortex at the through hole. The spiral air curtain cooling lens case is designed to be formed by utilizing a principle that whirlwind generates low temperature and negative pressure in the center of an air duct, protects a lens from being not radiated by high temperature, greatly enhances the cooling effect and can absorb away dust and oil contaminations on the lens because the central air pressure of the whirlwind can be less than peripheral air pressure by 20 percent, thereby achieving very obvious dust removing effect.
Description
Technical field
The present invention relates to observe in a kind of high-temperature heater stove the protective device of camera lens, especially a kind of spiral air curtain cooling lens case of high-temperature industrial television.
Background technology
High-temperature industrial television is a kind of equipment that high temperature heat-agglomerating process is observed and monitored; it generally constitutes by observing camera lens and the outer TV demonstration of stove and camera lens control protective device in the cover high-temperature heater stove; operating personnel can be by observing camera lens to all multifactor integrated and efficient image observations that carry out such as situation, graininess such as working condition, flame profile, charge level lifting in the stove in the stove; outside stove, show a kind of equipment that to intervene operating condition in the stove on the TV display.The high temperature industrial furnace kiln plant generally is the key equipment in the hot industry production run, its energy resource consumption height, and potential safety hazard is big, and hot worked flow process in the monitoring kiln body, be crucial and complicated technological process, be directly connected to the quality that improves product, reduce energy resource consumption.The most key is in process of production, if operating personnel can not understand the operating condition in the kiln comprehensively and in time, will stay very big hidden danger to the security of operation stove, so high-temperature industrial television is the visual plant guarantee of hot industry safe operation at present.
Observe camera lens in the stove because on-line operation in high temperature furnace; the hyperthermia radiation that is subjected to is very strong; must cool off and intercept; conventional at present method is to adopt two kinds of camera lens exogenous wind cold-peace water-cooleds; air-cooled promptly is to increase cooling jacket outside camera lens, is blown into gases at high pressure in cooling jacket, utilizes the transparency of gas; outside camera lens, form the high-pressure blast curtain and stop heat-flash radiation, len.Present product high pressure air curtain adopts the direct projection form, mainly there is following shortcoming: at first, the high pressure air curtain is because be the direct projection form, and internal-external heat exchange is fast, and cooling power is poor, must adopt gases at high pressure and air blast, could keep the cooling effect on camera lens surface reluctantly, if when temperature requirement is high, air cooling just can not meet the demands, must adopt gas cooled and two kinds of types of cooling of water cooling, just can meet the demands; Secondly, owing to adopt gases at high pressure and air blast, the moisture of gas and greasy dirt content height are piled up on camera lens easily, cause lens blur even cover, and influence the camera lens observing effect.
Summary of the invention
The objective of the invention is to, a kind of spiral air curtain cooling lens case of high-temperature industrial television is provided, camera lens cooling dome cooling effect is not high to cover technical matterss such as being difficult to eliminating with camera lens place dirt to solve.
The technical solution adopted for the present invention to solve the technical problems is: a kind of spiral air curtain cooling lens case of high-temperature industrial television, have cover body, and cover body central authorities offer through hole, are provided with the blower unit that makes the through hole form air eddy around the cover body through hole.
According to one of them embodiment of the present invention, further: blower unit comprises the camera lens cooling dome that is arranged in the cover body, camera lens cooling dome central authorities offer camera aperture, the camera lens cooling dome is all around to being outside equipped with fixed mount, fixed mount is welded in the cover body, and offering with the camera aperture on the camera lens cooling dome is the air inducing groove that center and spiral distribute, and air inducing groove and cover body inwall form the air inducing chamber, gapped between camera lens cooling dome and cover body, interstice coverage is 0.001～1.5mm.
In order to make wind to camera aperture central authorities, and the assurance air cooling effect, further: the camera lens cooling dome is round table-like, its side offers three to 15 road air inducing grooves, the scope of the angle angle between adjacent two walls of air inducing groove is 10～85 °, and it is beloid that the air inducing groove is presented.
In order to form air eddy better at the camera aperture place, a nearlyer step ground: the air inducing groove is an arc, and its camber scope is 0.1～0.5.
Beneficial effect of the present invention: the present invention utilizes spiral wind to produce low temperature and negative pressure principle design moulding at the center, air channel; len is not subjected to hyperthermia radiation; greatly improved cooling effect; the comparable ambient air pressure of spiral wind central pressure is low more than 10 simultaneously; dust on the camera lens and greasy dirt can be siphoned away, dust removing effects is very obvious.
