Description
Technical field
The invention belongs to Automatic Measurement Technique field, be specifically related to a kind of method that detects tamping tool hammer body running parameter in tamping coking process, also relate to the pick-up unit of implementing this detection method.
Background technology
Coke is a kind of very basic raw material of industry, has irreplaceable vital role at industrial circles such as iron and steel, chemical fertilizer and Coal Chemical Industries.Along with the growth of coke demand and the day by day shortage of coal for coking.In order to use no or little coking coal refining high grade coke, develop again TAMPING COKING PROCESS on coalingging the basis of coking on top.
Tamping coking is that coal mechanical means is made firm by ramming after compacting coal-forming wall, packs the coking technology of carbonizing chamber from coke oven side into.Produce coke because this method can be used weak caking coal cheaply, can also improve the quality and yield of coke simultaneously, be therefore developed rapidly in recent years.
In tamping coking process, the physical strength of coal wall and bulk density are the important parameters that ensures briquette quality, and it will directly affect the efficiency of coking and the quality of coke product.Raw coal is strength increase after making firm by ramming, and bulk density also can be by the 0.72t/m of bulk coal
3bring up to 1.10～1.15t/m
3.And the basis that ensures these important technical parameters is the merit of making firm by ramming of the unit's of being input to coal charge.And the so-called merit of making firm by ramming is the energy to the input of coal wall when coal charge in compactor is beaten coal bin repeatedly.Therefore, the tamping tool of coal charge in coal bin being made firm by ramming to compacting is the key equipment of tamping coking, and its advance and reliability directly affect the technical merit of tamping coking.
Tamping tool mainly by compactor, gearing, put forward 6 major parts such as hammer device, running gear, lubricating system and electric control operation device and form.When work, motor, under electric control system controls, is driven and is carried hammer device by mechanical drive, utilizes friction force by compactor upthrow, and behind arrival summit, compactor freely falling body is pounded Xiang Meiqiang, makes merit firm by ramming to the input of coal wall.Coal by repeatedly and carry hammer and make firm by ramming, height and the intensity of coal wall constantly increase, and finally reach the technical requirement that enters carbonizing chamber and carry out coke production.The concrete grammar that promotes compactor in tamping coking has multiple, but all possesses with energy compactor upthrow, utilizes hammer body to fall the feature of the impact kinetic energy stamped coal wall of generation.
Coal wall is made firm by ramming in process and must whether compactor normally be moved up and down and be monitored.Because may be subject to the impact of the factors such as equipment failure, mechanical wear and coal charge input quantity in tamping tool work, cause carrying in work hammer device can not be correct compactor is mentioned, cause not enough or the fault that completely can not upthrow of compactor upthrow height.Once occur that this phenomenon will cause significant impact to the work of tamping tool, gently make the not enough coal wall of input work intensity firm by ramming not high, coal charge heavy that compactor is constantly added is buried and is led to great " burying hammer " accident.
In coal wall is made process firm by ramming, also must detect the height of coal wall, in the time that coal wall height does not increase or increasess slowly, need to export batcher abnormal signal; When coal wall high growth arrives after preset value, need to stop coal and export and make settling signal firm by ramming.
Owing to there is no the detection technique of mature and reliable, the monitoring that current coal wall is made state firm by ramming mainly relies on artificial field observation to realize.High temperature, dust, harmful gas and the outdoor working environment of coke oven production scene make operator's labour intensity high, and often occur because of work carelessness or observe the inaccurate coal wall causing to collapse and equipment breakdown, affected greatly safety in production and the work efficiency of coke oven.Make the state-detection problem in process firm by ramming in order to solve coal wall, some detection techniques and method have also been studied by recent domestic producer.
The method of at present conventional measurement compactor motion state has:
Elastic Contact wheel measurement technology.This technology utilizes latch plate that a friction pulley is pressed on the hammer stem of compactor, and in the time that compactor moves up and down, friction pulley rotates thereupon, then by the rotation situation of the device measuring friction pulleys such as photoelectric encoder, thereby indirectly measures the motion state of compactor.Owing to making firm by ramming, on-the-spot mechanical vibration are very large, and friction pulley is easy to beat on hammer stem, cause measurement result very coarse inaccurate.Because the method is contact type measurement, the wearing and tearing of friction pulley in long-term work and on-the-spot coal dust adhere to the friction factor that all can reduce friction pulley and hammer stem, cause measuring system cannot work because skidding.
Conventional coal wall height measurement method has at present:
After making end firm by ramming, can pass through many measuring methods, comprise the commercial measurement coal wall height such as supersonic sounding, radar range finding and infrared optics range finding.But in the process of making firm by ramming, multiple compactors are beaten coal wall repeatedly up and down, cause above-mentioned measuring method cannot be worked because strongly disturbing or blocking.Therefore also there is no at present the ripe method for the real-time measurement of the process of making firm by ramming coal wall height, existing method can only made firm by ramming, compactor could be realized detection after rising, and therefore in current stamp-charging coke is produced, mainly still relies on manual observation and manual operation to ensure the normal work of tamping tool.
