Abstract
Survey stifled system online the invention discloses a kind of blast furnace coal gun, it is related to ironmaking equipment manufacturing technology field, it is included in the radio temperature sensor being equipped at the branch pipe of pulverized coal injection distributor for detecting the branch pipe surface temperature, the information of the branch pipe surface temperature is transmitted to terminal collector by the radio temperature sensor, this temperature information is passed to terminal by the terminal collector by interchanger.The present invention can solve that labor intensity is big, and installation difficulty is big, and installation period is long, safeguards the problem of relatively cumbersome.
Description
Technical field
The present invention relates to ironmaking equipment manufacturing technology fields, especially a kind of that stifled on-line system is surveyed for blast furnace coal gun.
Background technology
Blast furnace coal gun is by levigate coal dust, is sprayed into stove from blast-furnace tuyere coal rifle after distributor, with substitute for coke
Play a part of to provide heat and reducing agent, so as to reduce coke ratio and pig iron cost, whether blast furnace coal gun work is normal, is under blast furnace
The key that portion adjusts.Blast furnace coal gun blocks, and blast furnace circumferencial direction injecting coal quantity can be caused uneven, also there is spray in large-blowing coal
Coal amount not foot phenomenon, coal rifle duration of congestion is longer, and processing is more difficult, not only increases the labor intensity of operative employee, also affects
The service life of coal rifle.
Common coal rifle is surveyed there are mainly three types of blocking methods:First, manually on-the-spot make an inspection tour, rule of thumb by vision and touch
Feel is judged that this mode will depend on working experience, if lacked experience, cannot find that rifle is blocked up in coal powder injection in time, and
Increase labor intensity;Second is that judged by installing solid flow switch on coal spraying pipeline, this mode cost
Height, installation difficulty are big;Third, judging that installation period is long by wired temperature detecting element, safeguard relatively cumbersome.
Invention content
The object of the present invention is to provide a kind of blast furnace coal guns to survey stifled system online, and it is big that it can solve labor intensity,
Installation difficulty is big, and installation period is long, safeguards the problem of relatively cumbersome.
To solve the above-mentioned problems, the technical solution adopted by the present invention is:This blast furnace coal gun surveys stifled system online, including
The radio temperature sensor for detecting the branch pipe surface temperature is equipped at the branch pipe of pulverized coal injection distributor, it is described wireless
The information of the branch pipe surface temperature is transmitted to terminal collector by temperature sensor, and the terminal collector is by this temperature information
Terminal organ is passed to by interchanger.
In above-mentioned technical proposal, more specifically scheme can also be:In the pulverized coal injection distributor and the terminal
Wireless repeater is equipped between collector, the terminal collector is by the wireless repeater by the branch pipe surface temperature
Temperature information passes to terminal by interchanger.
Further:The terminal is computer.
Further:The radio temperature sensor is patch type radio temperature sensor.
Further:Described is MOXA interchangers.
By adopting the above-described technical solution, it compared with prior art, the present invention has an advantageous effect in that:Due to this hair
Bright to be equipped with radio temperature sensor at the branch pipe of pulverized coal injection distributor, radio temperature sensor is by pulverized coal injection distributor
Branch pipe at temperature by wireless signal transmission to wireless acquisition terminal, this temperature information is transferred to by wireless acquisition terminal again
Terminal, terminal can judge whether blast furnace coal gun blocks according to this information, go on-the-spot make an inspection tour without worker, alleviate worker
Labor intensity, present invention installation is simple, and installation period is short, easy to maintain.
Description of the drawings
Fig. 1 is the block diagram of the present invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples:
Blast furnace coal gun shown in FIG. 1 surveys stifled system online, including being located at the pulverized coal injection distributor 1 of blast furnace side in pulverized coal injection
The radio temperature sensor 2 for detecting branch pipe surface temperature is equipped at the branch pipe of distributor 1, radio temperature sensor 2 passes through
Wireless signal is connect with terminal collector 4, and wireless repeater 3 is equipped between pulverized coal injection distributor 1 and terminal collector 4,
Terminal collector 4 and interchanger 5 are connect respectively by wireless signal with wireless repeater 3, and in the present embodiment, terminal 6 is calculates
Machine.Interchanger 5 is connect by ethernet communication interface with computer.Computer judges coal rifle by neural computing method
Stifled rifle situation.
In the present embodiment, radio temperature sensor 2 is patch type radio temperature sensor.Interchanger 5 is MOXA interchangers.
When blast furnace works, the radio temperature sensor 2 for being attached to the branch pipe of pulverized coal injection distributor 1 detects the surface of branch pipe
The situation of change of temperature, and this situation of change by wireless signal transmission to wireless repeater 3, wireless repeater 3 receives
This information is transmitted to terminal collector 4 after this change information, terminal collector 4 is by Ethernet by information conveyance to exchanging
Temperature information is transported to computer by machine 5, interchanger 5 according to ICP/IP protocol, and computer can timing monitoring coal powder injection
The real time temperature of each branch pipe of distributor, and the historical temperature of each branch pipe of coal powder injection distributor is depicted as curve, while monitor at any time
The stifled rifle warning message of each branch pipe of coal powder injection distributor, and judge that coal rifle blocks up rifle situation by neural computing method.
The present invention judges duration 5 seconds to blocking up rifle judging nicety rate 100%, stifled rifle.By judging that coal rifle blocks up rifle in time, improve
Blast furnace processing coal rifle blocks up rifle efficiency, improves injecting coal quantity for blast furnace, reduces coke ratio and create condition.
