Description
Technical field
The utility model belongs to the outer technical field of imaging of blast furnace red, rotates automatically more particularly to a kind of blast furnace imaging device
Device.
Background technique
In blast furnace production process, in order to monitor the working condition and the condition of production in furnace in real time, need for blast furnace installation
Industrial Monitored Control System, it is general using the infrared imaging camera lens for being mounted on furnace roof, real-time continuous monitoring is carried out to situation in furnace.
Blast furnace imaging device is crossed preformed hole and is directly installed on blast furnace roof, carries out real-time continuous prison to the condition of production in furnace
Survey, on the monitor of control room can to the motion conditions of oscillating chute, the distribution situation of charge level in furnace, internal furnace charge
Seat material, situations such as the expecting that collapse are observed in real time, this has guidance to the control of conditions of blast furnace, energy saving, raising molten steel quality
Meaning.
Due to being high temperature, environment dusty, high humility in blast furnace, at the same it is there is also about the pressure of 0.2MPa in furnace and very strong
Ascending air, so camera lens is easy to be contaminated.In the case where continuous production, only holding lens cleaning does not tie ash,
It can guarantee that the image clearly of system is stablized, achieve the purpose that inner operating monitors in real time.Therefore for imaging device protection and
There is the protection of abnormal conditions (overtemperature stops the supple of gas or steam, cuts off the water) and the on-line maintenance in blast furnace continuous production process especially weighs
It wants.
High temperature imaging protective device and protection system have following two form at present:
1. plug-in type --- this structure is by imaging device protective jacket by being monitored in ball valve insertion State of Blast Furnace.It is this
Structure does not automatically exit from protective device, and the personnel that need repairing manually repair protective jacket extraction, when exception occurs in system
Or when there is overtemperature alarm, often maintenance personal has little time to extract video camera protective jacket in time to live, therefore in such case
Lower video camera or other monitoring devices and camera lens are easy to be burned out.In addition when needing on-line maintenance, due in State of Blast Furnace
Pressure is positive pressure (about 0.2MPa pressure) during maintenance personal extracts protective jacket and closes ball valve, to overcome the pressure in furnace
Also blast furnace gas to be prevented to be possible to leak outside simultaneously, therefore there is very big security risks.
2. flashboard valve type --- this structure is that Pneumatic gate valve is mounted on to imaging device protective jacket front end, when system occurs
When abnormal conditions or overtemperature alarm, slide valve is automatically closed to protect video camera (or other monitoring devices) not to be damaged.But this
There is certain limitations for kind structure, because entire protective device is installed in outside blast furnace furnace wall, video camera probe is without slotting
Enter into furnace, therefore the visual field is smaller, furnace wall aperture is larger.There is this structure also not automatically exit from protection system again, although
Pneumatic gate valve is mounted with before video camera protective jacket, and when abnormal conditions or overtemperature alarm occurs in system, slide valve can be certainly
It is dynamic to close protection video camera and camera lens, but to be nothing like ball valve sealing effect good for the sealing effect of slide valve, it is online when needing
Security hidden trouble described in the formula of being previously inserted into is equally existed when maintenance.
To solve the above-mentioned problems, one kind is disclosed in Chinese patent application the 201410557357.Xth by the applicant
" blast furnace imaging device exits protective device " submitted, Fig. 1 are that the blast furnace imaging device exits protective device structure schematic diagram.Such as
Shown in Fig. 1, the blast furnace imaging device exits shell 1, fire door 2, ball valve 3 and the cylinder 4 that protective device includes connection,
In:
The cylinder 4 includes cylinder body 41, piston 42 and piston rod 43, and the piston rod 43 is hollow structure and left end is opened
Mouthful, the right end of the piston rod 43 is connected to the piston 42, connecting rod 44, the connecting rod 44 is provided in the piston rod 43
One end be connected to the right end of the piston rod 43, the other end for installing infrared imaging device 5, be provided on the cylinder body 41
Cooling gas inlet 411 is provided with stomata 421, position corresponding with the stomata 421 on the piston rod 43 on the piston 42
Setting aperture is connected to the stomata 421 with space in the piston rod 43；
The shell 1, the fire door 2, the ball valve 3 and the cylinder 4 are set gradually from left to right and successively fixation connects
It connects, the left end opening of the shell 1, the piston rod 43 can be reduced to the right side of the ball valve 3, the piston when being fully retracted
43 bars protrude into the working position for the left end for making the infrared imaging device 5 be located at the shell 1 in the shell 1 when fully extended
And the stomata 421 is made to be directed at the cooling gas inlet 411.
It further includes controller that the blast furnace imaging device, which exits protective device,.
But find that the blast furnace imaging device exits protective device and has the following problems: in actual use
Infrared imaging device 5 is fixedly mounted on connecting rod 44, therefore can only take the work in blast furnace inner part region
The distribution situation of the motion conditions and charge level of making situation and the condition of production, especially oscillating chute cannot combine, if wanting to see
The overall picture in entire blast furnace is examined, at least needs opposite that two blast furnace imaging devices with different imaging angles are installed and exits protection
Device, it is clear that production cost can be increased substantially in this way, and can not usually be implemented because required operating space is excessive.
