Description
Technical field
The utility model relates to explosion rig field, relates in particular to a kind of dust diffusion that can prevent to produce in the rig operation process and the surface mine explosion rig of kicking up, and the dust guard that is used for this rig.
Background technology
Surface mine can produce a large amount of rock slags in using the rig process, the rock slag particle of discharging in boring footpath is not of uniform size, and particle diameter is more little, more difficult deposition, if do not control and handle, they will be dispersed in the production environment and go, the harm workers ' health.Trickle rock slag deposits can be quickened galling to machine movement part, influence the machine operate as normal, shortens rig application life.During punching, a large amount of dusts that drill bit produces to around spray, not only influence environment, and pass the sight line that dust that horizontal table upwards sprays influences the meeting operator.
Current, open-air mining-drilling machine dust pelletizing system is divided into two kinds of wet type and dry types by dedusting method.
Wet dedusting system mainly is made up of water supply installation, geomantic omen mixing arrangement, aperture slag-draining device etc.; During rig boring, the press water that water supply installation provides gets into the geomantic omen mixing arrangement, mixes with air pressure; The rock dust that feasible fragmentation is got off at the bottom of the hole and along in the hole wall uphill process by moistening; The rock dust pelletizing that congeals into moistening or semifluid magma drain into the aperture, blow to rig one side by the aperture slag-draining device.
The dry dust removal system directly separates the dirt gas mixture and captures, water not, better dust removal effect.The dry dust removal system mainly is made up of dust hood, flow tank, other chamber cyclone dust collectors, mechanical pulsing sack cleaner and ventilating fan.During rig boring, the pull-out type ventilating fan starts, and forms negative pressure in the dust pelletizing system dust hood, and dust gets into dust hood under the drive of rig return air.Particle diameter is in the dust major part sedimentation in dust hood more than 100 microns; The granule dust is sucked gravity settling chamber by ventilating fan, and when the dirt gas of extraction got into than the expansion chamber of large space suddenly, flow velocity reduced; The particle that settling rate is big becomes the rock slag at the bottom of falling into the chamber, is emitted by automatic slagging mechanism.Thinner little dust gets into other chamber cyclone dust collectors with air-flow from outlet, and in cyclone dust collectors, air-flow is rotated down under the guiding of spirality top board; Thick dust gets rid of to outer wall under action of centrifugal force, and descends along hand of helix, falls into and unloads the dirt device; Fine solid particle rises from stack with air-flow; Get into the mechanical pulsing sack cleaner, under the effect of ventilating fan, the dust that gets into deduster is delayed at the cloth bag periphery; Purge gas through the cloth bag filtration gets into upper box body, at last through going out to pile up.
The most basic requirement of dry dust removal system is can be earlier being surrounded to all dusts that spray all around before dust-filtering.This requirement is easy to realize in single angle boring fashion, yet when holing with multiple angles, just is surrounded very difficulty to dust fully.
Therefore, be necessary to improve dust pelletizing system, improve efficiency of dust collection, with the operating environment that guarantees cleaning and equipment application life of length.
