Description
Technical field
The present invention relates to a kind of mining cleaner,, can purify the deduster of the dust that produces in the coal digging operation particularly with the supporting use of coal excavation apparatus.
Background technology
At present; Matching used dust removing down-hole device all is a hydrofilter in the known coal digging operation; Dust-contained airflow through by continuous spraying moistening porous fiber layer or wire lath; Because fibrage or wire lath inner filling water have strengthened dust and water and fiber or wiry the contact and collision probability, reach the purpose of dedusting.But this kind dust collector efficiency is low, and respirable dust is difficult to filtering, and total efficiency of dust collection is less than 98%, and especially the respirable dust efficiency of dust collection makes dust heavy working environment in down-hole can not get basic improvement less than 95%, has a strong impact on the healthy of workman; In addition, existing deduster does not have the online detection alarm function of gas, can not control closing down of ventilation fan automatically according to the concentration of gas, has safety of coal mines hidden danger.
Summary of the invention
In order to overcome effectively filtering respirable dust and do not have the deficiency of the online detection alarm function of gas of existing mining deduster; The present invention provides a kind of mining horizontal dry method bag dust collector; This bag dust collector adopts the dedusting of horizontal dry method filter bag, and total efficiency of dust collection is greater than 98%, and particularly the removal efficient to respirable dust reaches more than 99.5%; Can greatly improve the underground work environment, reduce the risk that the workman suffers from pneumoconiosis.This is mining, and horizontal dry method bag dust collector has also increased online detection alarm device of gas and ventilation fan automatic switch control device; Can control the startup of ventilation fan automatically and stop according to the concentration of gas; Greatly reduced by manual work and carried out Monitoring and Controlling and the error that possibly occur, improved the safety in colliery.This bag dust collector also can be used for the processing of roads and tunnels dust that engineering construction produces.
The technical solution adopted for the present invention to solve the technical problems is: mining horizontal dry method bag dust collector; Comprise underframe and be arranged on dust catcher, the electric control box on the underframe; It is characterized in that said dust catcher is made up of cleaner head, hose, the online detection alarm device of gas, ventilation fan, air collecting box, glass filter bag, dust deposited case, cleaner head, hose, ventilation fan, air collecting box, filter bag, dust deposited case connect successively; Said glass filter bag both ends open is connected with dust deposited case with air collecting box respectively; The online detection alarm device of gas is arranged on ventilation fan air intake place, and bottom, the inboard both sides of said dust deposited case is provided with sparge pipe, and the dust deposited case lower end has ash discharging hole; Ash discharging hole is provided with aperture size adjustment valve, and said electric control box is provided with the automatic control system of band PLC programming Control program.
Said ventilation fan is that mining anti-riot pull-out type is to the axial flow rotary booster.
The online detection alarm device of said gas in use can spread out of two groups of signals: the first is reported to the police when the gas density of air intake reaches 1% automatically; It two is when the gas density of air intake reaches 4%, and this signal is passed to mining cartridge type deduster electrical equipment automatic control system, breaks off the ventilation fan power supply; When the automatic control system less than 1% time of the gas density in the tunnel starts the ventilation fan power supply automatically.
Said glass filter bag is a glass filter bag group, is made up of 10-20 monomer glass filter bag.
The sparge pipe that bottom, the inboard both sides of dust deposited case is provided with; Be used for spilling from the dry dust that filter bag drops wet, the dust deposited case lower end has ash discharging hole, by valve regulated ash discharging hole size; Moistening dirt is discharged dust deposited case from ash discharging hole, causes secondary pollution when avoiding dry dust to discharge.
Ventilation fan air intake place establishes the online detection alarm device of gas, and this device contains gas concentration sensor, can monitor the gas density at ventilation fan air intake place in real time, and this device can be reported to the police automatically when the gas density of air intake reaches 1%.The gas density signal can also be real-time transmitted to ventilation fan automatic switch control device, and this device is located in the electric control box, and electric control box is located on the deduster underframe.When ventilation fan air intake place gas density reaches 4%, cut off the ventilation fan power supply automatically, avoid electric spark actuation gas; When the online detection alarm device of gas detects gas density in the tunnel less than 1% the time; Ventilation fan automatic switch control device will start the ventilation fan power supply automatically; Make bag dust collector get into duty, promptly realize bag dust collector work whether automatic control according to gas density.
This bag dust collector and the supporting use of development machine.Bag dust collector is located at development machine rear end, two and transports end, and in two fortune and development machine junction, the heading end of the cleaner head of bag dust collector front end and hose and development machine closely accompanies, and is convenient to the dust that produces when very first time processing development machine is mined.During bag dust collector work; By ventilation fan suction air collecting box, it is inner that the dusty gas in the air collecting box gets into filter bag through cleaner head, hose for dusty gas, and dust is stopped filtration by filter bag and stays in the filter bag; Air can be discharged from the filter bag external surface through the filter bag inner surface becomes not dust-laden pure qi (oxygen); The dust of staying in the filter bag is blown into dust deposited case by the wind comes from of air collecting box, opens sparge pipe and ash discharging hole valve during ash discharge, spills wet dirt through water and discharges dust deposited case from ash discharging hole.
Beneficial effect of the present invention also has, and when improving total efficiency of dust collection, the removal efficient of respirable dust is improved greatly, can effectively improve the serious working environment of down-hole dust, reduces the risk that the workman suffers from pneumoconiosis.The present invention can also control the startup of ventilation fan and stops according to the concentration of gas automatically; Promptly realized bag dust collector work whether automatic control; Greatly reduced by manual work and carried out Monitoring and Controlling and the error that possibly occur, when improving safety of coal mines property, reduced labour intensity.
