Description
Technical field
The invention belongs to down-hole atomizing de-dusting technical field, more particularly to a kind of iron ore drop shaft smart spraying depositing dust dress
It puts and control method.
Background technology
Iron ore is important one of basic industries, and the worker's number for being engaged in iron ore exploitation is numerous.With mining rate and machine
The raising of toolization level, the dust pollution in mine operation area is apparent, influences the safety of downhole production, especially endangers shop floor worker
Health, therefore there is obvious necessity for atomizing de-dusting.
In traditional mine, dedusting uses manual control or timing, position control watering and sprayer substantially, exists
The problems such as inefficiency, waste water resource.With the development of electronic technology, employed between frame with reference to practical application Some Enterprises
Auto spraying, ore drawing auto spraying, the device for reducing dust according to some intelligents such as dust concentration auto sprayings.But not yet
The device for reducing dust at ore deposit is unloaded in appearance for iron ore drop shaft, and due to the complexity of actual field environment, common device for reducing dust is not
It can be applicable in well.
More pervasive device for reducing dust detects dust concentration using light scattering method sensor of dust concentration at present, according to setting
Fixed threshold values control spraying device.But sensor of dust concentration range ability is limited, easily by dust pollution, zero migration is tight
Weight, needs often to clear up, accuracy of detection is low, and error is up to 25%.The operating current of sensor is big simultaneously, sensor and controller
Required distance it is shorter.However general wind-force is larger at drop shaft, dust recycling is fast, and sensor of dust concentration detection lag needs
Depositing dust area is big, it is desirable that more complete equipments carry out depositing dust, and equipment cost is high, and water utilization rate is low.
Common device for reducing dust also has the device for reducing dust such as sound control type, light-operated, touch controlled type.But it cannot all be applicable in well
The depositing dust at drop shaft, the source that this kind of sensor cannot effectively distinguish signal are staff or locomotive, can not be distinguished
Mine locomotive type (locomotive divides loaded vehicle and empty wagons, and loaded vehicle is divided into the loaded vehicle of different dress ore deposit volumes, and empty wagons is including inspection car etc.), no
Can ore deposit amount adjustable spraying amount, waste of resource be filled according to locomotive.And be easily disturbed, accuracy in detection is low.
A kind of existing patent " high-pressure micro-mist dust suppression equipment ", " a kind of anion suppressing dust with dry mist purification method and device ", " one
The clean dry fog cleaner of kind intelligent self-cleaning ", " a kind of double centrifugal dust collection devices of dry fog moisture film and its dust collecting process " all can not achieve
Automatic dust removing effect.Patent " car dumper shed region dry fog cleaner " is controlled according to photosensitive sensors, and patent is " a kind of
Dry fog dedusting control system and its control method " according to sensor of dust concentration carry out auto spraying, all there are it is above-mentioned the shortcomings that,
Iron ore drop shaft environment is not suitable with, iron ore drop shaft dust removal requirement can not be met.

Reach when drop shaft unloads ore deposit and start spraying operation in advance, i.e., reach region one in locomotive and be not in dead ship condition, control high pressure spray
The corresponding solenoid valve of mouth group is opened and controls unlatching water, sprays in advance, creates wet environment, and manufacture isolation mist wall prevents from unloading
Dust large area is spread during ore deposit；When detect locomotive reach drop shaft unload start to unload ore deposit at ore deposit when, i.e., locomotive enter region two and
When being not in dead ship condition, then the corresponding solenoid valve of ultrasonic nozzle group is controlled to open and controls unlatching water, carried out quick high
The depositing dust operation of effect；When detecting that locomotive leaves after drop shaft is unloaded at ore deposit or is in dead ship condition due to unexpected situation, that is, work as
When locomotive enters region three, delay control, it is ensured that preferable dust-laying effect；After the signal that can't detect locomotive, then control height
The solenoid valve of nozzle sets and ultrasonic nozzle group is pressed to close, terminates depositing dust operation.And staff can be according to actual condition
Pass through the button sets itself and the mounting distance of modification time parameter and RFID card-reading apparatus on control cabinet, optimization depositing dust effect
Fruit.
Compared with prior art, advantage of the invention is that：
The present invention has locomotive type (locomotive of difference dress ore deposit volume) automatic feedforward control according to RFID identification, prevents
Dust recycling directly in the dedusting of dust source, saves water resource, improves iron ore underground work environment, effectively prevent dust to people
The infringement of body is fitted, and closes the demand of iron ore drop shaft dedusting.
