Description
Technical field
The invention belongs to coke oven technology, more particularly to a kind of detection method of coke oven coal filling mouth blocking.
Background technology
Coal filling hole is that coking mixed coal loading carbonization chamber must be had no coal filling hole at present by top dress coke oven coal charging car by passage
The method of the detection of blocking.The mechanical lance formula detection device of existing coke oven coal filling mouth bell sorption, which, which is installed on, coalings
Che Shang, stopper removing machine are promoted after taking lid, and after bell meets the lance of the device, /V detects bell.
Existing bell sorption detection device there are the problem of：First, device is yielding, take a machine take lid after upper limit be equipped with
Deviation causes detection to fail；Second is that at present after the commonly used heat-insulated bell of double-layer energy-saving type, once the lower floor of double-layer furnace cover takes off
Fall, which can not detect, chute blockage when still causing to coaling.
More than reason causes current bell sorption to confirm that device application is difficult, is blocked up caused by bell is not normally-open
Coal phenomenon is more frequent.In coke oven destructive distillation production process, free charcoal is accumulated at coal filling hole, forms time burnt, blocking coal sometimes
Mouthful, coal will also result in chute blockage at this time.During coke oven coal-charging, once coal filling hole chute blockage occurs, coal is easy to send out at high temperature
Raw phenomenon of burning with anger of smoldering, pollutes environment.Chute blockage processing is also extremely difficult, need to each device of charging car be all recovered to raw bits
It puts, removes charging car, then after manual cleaning coal piling, coal filling hole time coke etc. is opened or cleared up to the bell of non-sorption with perching knife
Sundries, environmental pollution is serious in the process, and coal flame and raw coke oven gas are largely excessive, also there is very big security risk.Chute blockage processing
It finishes, needs that manually coal piling is sent into carbonization chamber.
The content of the invention
It is an object of the invention to provide the detection methods that a kind of coke oven coal filling mouth blocks, and can find that coke oven carbonizes in time
Room coal filling hole blocks, chute blockage failure caused by coaling operation when avoiding the coal filling hole from blocking, it is ensured that the safety for the treatment of people reduces dress
Environmental pollution caused by due to processing coal filling hole blocking in coal operation process mitigates the burden of hand sweeping.
In order to achieve the above objectives, the technical scheme is that：
The detection method that a kind of coke oven coal filling mouth blocks, temperature measuring equipment is installed on charging car, corresponding each coal filling hole
An if temperature measuring equipment；After charging car stopper removing machine takes lid, before sleeve of coalingging declines, the temperature in temperature measuring equipment detection coal filling hole region,
And transfer data to the vehicle-mounted PLC system of charging car；Temperature measuring equipment and charging car stopper removing machine synchronization action, charging car stopper removing machine take
After lid to the upper limit, temperature measuring equipment stretches out simultaneously, and alignment carbonization chamber coal filling hole carries out thermometric, and temperature is 950 in carbonization chamber coal filling hole
~1000 DEG C, therefore, the temperature that temperature measuring equipment measures blocks, due to stifled at 800 DEG C or more if coke furnace carbonization chamber coal filling hole occurs
Plug thing completely cuts off carbonization chamber and outside, and temperature measuring equipment can not measure relevant temperature；The numerical value that temperature measuring equipment is measured includes control
System is set below sending alarm at 500 DEG C, and coherent signal includes charging car operation interlock condition, is examined with this according to scene
The temperature data of survey judges whether coal filling hole blocks, and after only obtaining the normally-open signal of bell, charging car just starts coal work
Industry；If less than 500 DEG C, show coal filling hole there are clogging, operating personnel block corresponding coal filling hole according to alert locations
Object is handled；Meanwhile the output phase answers coal filling hole block information to charging car operating terminal, be simultaneously stopped charging car it is subsequent plus
Coal acts.
Preferably, the temperature measuring equipment is arranged at charging car one and fixes in guide sleeve, and the lower coal for stretching into corresponding coal filling hole slips
In slot, lower coal chute one side open one for temperature measuring equipment disengaging through hole, through hole top installation one fan can freely openable it is small
Door.
Preferably, the temperature measuring equipment is an infrared thermometer, is mounted in stainless steel tube, under stainless steel tube one end
Portion's perforate so that the temperature measuring head direction of infrared thermometer is downward, the position alignment carbonization chamber coal filling hole of stainless steel tube perforate.
Preferably, the stainless steel tube rear end car silk, diameter and a drive cylinder piston rod end diameter match, and
It is connected in the drive cylinder piston rod end；The perforate at stainless steel tube caudad, by call wire from stainless steel tube tail hole
In pierce into, be connected with infrared thermometer, the drive cylinder be mounted on charging car fixed frame on.
Testing principle of the present invention：
Coke oven production process completely cuts off the process of air heating destructive distillation for coking mixed coal in carbonization chamber, it is generally the case that
Indoor temperature is carbonized more than 1000 DEG C.In coke oven production process, coal filling hole bell closed state, bell surface temperature for 200~
300 DEG C, during coaling operation, bell is opened, and is coaling and is finished, and bell is closed, and bell on-off action is performed by charging car corresponding mechanism.
By installing temperature measuring equipment on charging car, to coal filling hole bell location detection, the front and rear temperature of bell opening and closing is utilized
If difference less than 500 DEG C, shows coal filling hole there are clogging, and coherent signal includes charging car operation interlock condition, only
To after the normally-open signal of bell, charging car just starts coal operation.
Beneficial effects of the present invention：
Detection technique method of the present invention fully combines coke oven productive prospecting, charging car job behavior and automatic measurement technique,
Bell can quickly and effectively be detected to have turned on, eliminate hole chute blockage of coalingging caused by charging hole lid is not switched on, stopping problem of coalingging is kept away
Exempt to smolder in coke oven coal-charging operation process the security risk burned with anger in environmentally friendly risk and fault treating procedure.This detection method is answered
Technical support is provided with to realize that charging car is unmanned.This detection method is the most Direct Inspection Technology that coal filling hole blocks, can
Greatly improve by property.
Difference with the prior art of the present invention is：
The method of the present invention is taken full advantage of under coal filling hole blocked state, and coal filling hole regional temperature is low, and coal filling hole is normally-open
Under state, coal filling hole regional temperature raised characteristic suddenly detects the regional temperature by temperature measuring equipment and changes, and direct detection adds
The problems such as whether coal mouth is normally opened, and bell is not normally-open, and coal filling hole time coke blocks can detect judgement together, it is ensured that abnormal
In the case of can dispose in advance, avoid coal filling hole block caused by coaling operation when chute blockage failure, have it is safe efficient, cleaning etc.
