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 cartridge type deduster; This cartridge type deduster 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 the cartridge type deduster 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 cartridge type deduster 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 cartridge type deduster; Comprise underframe and be arranged on dust catcher, the electric control box on the underframe that it is characterized in that said dust catcher comprises cleaner head, hose, blower fan, urceolus and filter bag, cleaner head, hose, blower fan connect the air intake of urceolus successively; Filter bag is arranged in the urceolus; Said filter bag is that an end opening, an end are remained silent, and the closed end of filter bag is in face of air intake, and the openend of filter bag is towards the air outlet of tail end; Said urceolus downside is provided with a plurality of ash discharging holes; Urceolus downside inwall is provided with sparge pipe, and described ventilation fan air intake place is provided with the online detection alarm device of gas, and said electric control box is provided with the automatic control system of band PLC programming Control program.
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 automatic control system, and control program 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.
The quantity of said filter bag is 6-15.
Said filter bag adopts the flame-retardant and anti-static glass fiber material to process.
Said urceolus tail end is provided with the bonnet of fast-assembling screw flange arrangement.
Said ventilation fan is that mining anti-riot pull-out type is to the axial flow rotary booster.
The flow direction according to dry dusty gas connects cleaner head, hose, ventilation fan and urceolus in order.Urceolus perisporium sealed air-tight, built-in a plurality of dust-filtering bags, filter bag adopt the flame-retardant and anti-static glass fiber material to process; The urceolus tail end is provided with fast-assembling screw flange arrangement, is convenient to change filter bag and maintenance, and the wet technique coal ash discharging mouth is located at the lower wall of urceolus; Ash discharging hole quantity is decided according to the length of urceolus, and the urceolus lower wall also is provided with sparge pipe along its length, is used for spilling the dry dust that drops from filter bag wet; Moistening dirt is discharged urceolus from ash discharging hole, causes secondary pollution when avoiding dry dust to discharge.
Ventilation fan air intake place is provided with 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 reached 4%, ventilation fan automatic switch control device got into duty, cuts off the ventilation fan power supply automatically, avoids 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 the cartridge type deduster get into duty, promptly realize cartridge type deduster work whether automatic control according to gas density.
The supporting use of the present invention and development machine.The cartridge type deduster is located at development machine rear end, two fortune machines upper end, and in two fortune machines and development machine junction, the cleaner head of cartridge type deduster front end and the heading end of hose and development machine closely accompany, and is convenient to the dust that produces when very first time processing development machine is mined.During the work of cartridge type deduster; Dusty gas through cleaner head, hose by ventilation fan suction urceolus; To get into filter bag inner by being located at filter bag external surface in the urceolus, and dust is stopped by filter bag and filters and attached to the filter bag external surface, air can get into the inner not dust-laden pure qi (oxygen) that become of filter bag through the filter bag external surface; Discharge from the filter bag tail end; The dust of filter bag external surface drops on the laying dust district on the urceolus downside inwall, and sparge pipe spills dry dust in wet, moistening dirt and dust-containing water is discharged urceolus 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 cartridge type deduster 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.
