Abstract
The utility model relates to a monitor for a blast furnace. The device has an optical fiber camera component used for collecting the actual work signal, a signal processing unit used for receiving the signal of the optical fiber camera component and converting the signal into the visual signal, and a monitor which can receive the visual signal sent by the signal processing unit and display the visual signal in terms of pictures. The imaging head of the utility model is smaller in volume but large in signal collection rang, and the optical fiber components in the imaging head are easy to be replaced and convenient in use.
Description
Technical field: the novel a kind of blast furnace that is used to monitor, the particularly watching device of Top of BF zone operating mode of relating to of this reality.
Background technology: the blast furnace in the real work, states such as the distribution of the granularity of the raw material of dosing, raw material and air-flow all have strict requirement in it, such as iron ore raw material and the coke that acts as a fuel, when adding these raw materials in the blast furnace, should follow predetermined in advance accumulation form, this accumulation form rule of thumb feeding or can not reach gratifying degree by the predefined program feeding of mechanical means, for this reason, also should monitor inner operating randomly, so that adjust the distribution of raw material in the stove at any time.And above-mentioned raw materials is piled up or distribution can be come out by direct reaction from the charge level that adds the raw material in the stove, so the charge level monitoring equipment is now generally adopted.
Known blast furnace charge level monitoring equipment comprises ray or temperature imaging head unit, promptly infrared radiation signal in the blast furnace is changed into the temperature signal of charge level with this imaging head, convert this signal to vision signal by the specific signal treatment unit then, show by the vision signal of watch-dog again input.But, because above-mentioned ray that adopts or temperature imaging head, from the overlay area of its image-forming principle and required imaging, should possess has relatively large diameter comparatively ideally the charge level distribution to be reflected exactly, otherwise can't finish imaging task.Because imaging head is to need directly or extend into parts in the stove by safety guard, it will be subjected to the erosion of furnace high-temperature and fluidised form gas, and prior art to solve high temperature and gas erosive the only resource be to adopt directly to feed cooling gas in imaging head it is cooled off at random, this cooled is safeguarded relevant with the size of imaging head volume, and bulky imaging head need feed bigger airshed; In addition, what above-mentioned imaging head adopted usually is the higher optical imagery camera lens of cost, and this camera lens is worked very easily impaired under severe environment such as high temperature, and is difficult for after damaging changing.
Summary of the invention: task of the present utility model provides a kind of less shooting part of volume that utilizes to obtain the watching device on the blast furnace of being used for of optical field of view in a big way.
The utility model proposed is used for watching device on the blast furnace, have one and be used to gather the optical fiber camera assembly of actual condition signal in the blast furnace and the signal processing unit that is used to receive the signal of optical fiber camera assembly and converts thereof into vision signal, but and the vision signal sent of received signal processing unit and can be with its watch-dog that reflects in the mode of image.
The output terminal of described watch-dog also is provided with picture storing apparatus.
Described optical fiber camera assembly comprises imaging fiber head and the cooling gas circulation device that is arranged in the blast furnace, and is used for joint flange that imaging head and gas communication device are combined.
Described gas communication device has a gas communication pipe fitting, and this pipe fitting is provided with radially input hole.
Because the utility model adopts the optical fiber camera assembly as imaging head, and optical fiber components has the goodish high temperature resistant and intrinsic propesties of collecting optical signalling, thus adopt the volume of imaging head of this kind structure less relatively, but the scope of collection signal is really quite big; It is very little to use the imaging head of this kind structure need feed the cold gas scale of construction simultaneously, thereby can reduce its use cost greatly; In addition, this device has adopted a joint flange, dismantles or install optical fiber components in the described imaging head at an easy rate by this flange, and it is very easy to use.
Description of drawings: accompanying drawing 1 is the system flow synoptic diagram of an embodiment of the utility model.
Embodiment: referring to Fig. 1, the system flow that provides from figure comprises four parts altogether, i.e. optical fiber camera assembly 1, signal processing unit 2, watch-dog 3 and picture storing apparatus 4.Because signal processing unit 2 and watch-dog 3, and picture storing apparatus 4 all belongs to moulding product, thus do not provide its concrete structure in the accompanying drawing, but those of ordinary skill in the art can implement fully according to annexation shown in Figure 1.
The watching device that the utility model proposed is with an optical fiber camera assembly 1 is arranged, it comprises imaging fiber head 11 and carries the gas communication device of cooling gas for this imaging fiber head, and be used for joint flange that imaging fiber head 11 and gas circulation device are combined, described gas communication device is made of pipe fitting 12 and the radially input hole 13 that is arranged on the pipe fitting 12, is connected with gas supply member by input hole 13 radially.
Optical fiber camera 11 can be arranged on it in Top of BF, it can gather the optical signal of charge level in the stove, then it is fed back to signal processing unit 2, convert optical signal to vision signal by signal processing unit 2, again this vision signal is input in the watch-dog 3, and by watch-dog 3 inner operating is shown, the output terminal at watch-dog 3 also is provided with a picture storing apparatus 4 simultaneously, for inquiry in the future.
