In the fire coal production process of thermal power plant, the cost of fuel constitutes about the 80% of totle drilling cost, so ensureing into stove Coal is up-to-standard stable significant to the economic benefit safeguarding power plant.The error impact that analysis result is caused by sampling element Very big, existing as-fired coal sampling apparatus is arranged in the middle part of conveyer belt mostly, in belt runs by sampling head periodically by coal by skin Scraping on band, enter division equipment, unnecessary coal sample is carried back conveyer belt by bucket elevator.But the sampling head degree of depth is wayward, cross deep meeting Damage belt, crosses the most shallow, samples that under-represented (particularly CFB unit, at coal after Screening and crushing system at conveyer belt higher slice Piling up, ature of coal levels difference is bigger).
At present, as-fired coal weigh calibration equipment many employings carrying roller weigh, chain code dynamic check.But chain code check is installed relatively Complexity, is affected, after relatively testing with many factors such as zone face frictional force, chain code movable part resistances by conveyer belt tensile force, chain code Error cannot ensure, need to carry out physical goods inspection every year, major part factory coal handling system does not all design the feed bin of physical goods inspection and enters Material mouth, verifying work difficulty is big and precision is difficult to ensure that.
Solving coal handling system as-fired coal for specific aim to sample and problem present in checking procedure of weighing, the present invention proposes one Plant high accuracy as-fired coal sampling and verification integral system of weighing, by carrying out coal sampling the most automatically in coal spout, solve Above-mentioned coal sample devices is sampled the strongest problem uneven, representative.The corresponding biography received by computer control system The weight signal of sensor feedback, can complete automatic Weighing verification, solves that the work difficulty that chain code dynamic check exists is big, error The problem that cannot ensure.Make as-fired coal sampling and gage work automatization, precision.
Utility model content
The purpose of this utility model is to sample and present in metering process for coal handling system as-fired coal in prior art Problem and a kind of high accuracy as-fired coal sampling and verification integral system of weighing are provided, it is characterised in that the sampling of this as-fired coal and Weigh verification integral system by coal spout 1, coal sampler 2, sampling feed bin 3, conveyer belt 4, coal division keep sample equipment 5, from Dynamic packaging code-spraying equipment 6, computer control unit 7, belt conveyer scale gravity sensor 8, belt conveyer scale 9, electric door motor 10, Electrically operated gate 11, coal bunker gravity sensor 12, coal bunker 13 of weighing, bucket elevator 14, liftway 15, bucket elevator lifting motor 16 form;Wherein, Coal sampler 2 is installed on coal spout 1 side, as automatic sampling apparatus;The outlet of sampling feed bin 3 connects coal division and keeps sample equipment The entrance of 5, the keep sample standby sample outlet of equipment 5 of coal division connects the entrance automatically packing code-spraying equipment 6;Coal bunker gravity sensor 12 Lower section in coal bunker 13 of weighing;Electrically operated gate 11 is positioned at the lower section of coal bunker gravity sensor 12, and Electrically operated gate 11 outlet is positioned at belt conveyer scale 9 Front;Belt conveyer scale 9 is positioned at the lower section of conveyer belt 4;Computer control unit 7 by signal transmssion line respectively with coal sampler 2, code-spraying equipment 6, belt conveyer scale gravity sensor 8, electric door motor 10, coal bunker gravity sensor 12, bucket elevator liter are automatically packed Fall motor 16 connects.Bucket elevator 14 is positioned on liftway 15, and is connected with bucket elevator lifting motor 16.
The coal bunker gravity sensor 12 of described coal bunker 13 bottom of weighing periodically carries out counterweight verification.
Described coal division keeps sample the standby sample in equipment 5, through packaging code-spraying equipment 6 carries out packaging and coding preserves 30 automatically My god.
The beneficial effects of the utility model are: this utility model is sampled by carrying out coal the most automatically in coal spout, protects Uniformity and the representativeness of coal sampling are demonstrate,proved.The weight signal of respective sensor feedback is received by computer control system, can Complete automatic Weighing verifying work, solve the problem that the work difficulty that chain code dynamic check exists is big, error cannot ensure.Make Obtain as-fired coal sampling and weigh verifying work automatization, precision.For completing the automatic sampling work of as-fired coal and improving into stove Coal metering accuracy provides good Technical Reference.
Accompanying drawing explanation
Fig. 1 is high accuracy as-fired coal sampling and verification integral system structural representation of weighing.
Detailed description of the invention
This utility model provides a kind of high accuracy as-fired coal sampling and verification integral system of weighing the most right This utility model is further described.
As shown in fig. 1, the sampling of stove coal and verification integral system of weighing are by coal spout 1, coal sampler 2, sampling material Storehouse 3, conveyer belt 4, coal division keep sample equipment 5, automatically packaging code-spraying equipment 6, computer control unit 7, belt conveyer scale gravity sensitive Device 8, belt conveyer scale 9, electric door motor 10, Electrically operated gate 11, coal bunker gravity sensor 12, coal bunker 13 of weighing, bucket elevator 14, lifting are led to Road 15, bucket elevator lifting motor 16 form;Wherein, coal sampler 2 is installed on coal spout 1 side, as automatic sampling apparatus; The outlet of sampling feed bin 3 connects coal division and keeps sample the entrance of equipment 5, and the keep sample standby sample of equipment 5 of coal division exports to connect and automatically packs spray The entrance of decoding apparatus 6;Coal bunker gravity sensor 12 is positioned at the lower section of coal bunker 13 of weighing;Electrically operated gate 11 is positioned at coal bunker gravity sensor The lower section of 12, Electrically operated gate 11 outlet is positioned at the front of belt conveyer scale 9;Belt conveyer scale 9 is positioned at the lower section of conveyer belt 4;Computer controls single Unit 7 by signal transmssion line respectively with coal sampler 2, automatically packaging code-spraying equipment 6, belt conveyer scale gravity sensor 8, Electrically operated gate Motor 10, coal bunker gravity sensor 12, bucket elevator lifting motor 16 connect.Bucket elevator 14 be positioned on liftway 15 and with bucket Carry machine lifting motor 16 to connect.
