Abstract
The utility model relates to an orepass dust control mechanism. A communicating passage (3) is arranged at a position under each middle section (5), which is close to a branch orepass (4) communicating with the middle section (5), and both ends of the communicating passage (3) respectively communicate with an orepass (1) and a spoil orepass (2). The two orepasses are pressure release orepasses for each other. When an orepass system discharges ores, the air in front of the falling direction of ores is rapidly compressed (positive pressure area), so that impact air pressure is generated, the vast majority of impact airflow passes through a circular air path of 'orepass-communicating passage-spoil orepass-communicating passage-orepass' for the two orepasses are pressure release orepasses for each other via the communicating passages, so that the dirty air is closed and circulated in the system formed by the orepass and the spoil orepass, consequently, the dusty airflow spurted by the mouth of the branch orepass of each middle section is greatly reduced, and the pollution of dust on a ventilating system is reduced.
Description
Technical field
The utility model relates to a kind of drop shaft dust Control mechanism.
Background technology
Drop shaft is dustproof always to be the difficult problem of domestic and international dust control by ventilation circle.Because when unloading the ore deposit, there is the ore drawing discrepancy in elevation of rice up to a hundred even hundreds of meters in drop shaft, loose ore receives the restriction of the borehole wall; In the process that falls, produce similar piston type motion; Air in the drop shaft is sharply compressed, and during diversion drop shaft through each stage casing, impact air-flow vomits.Air-flow carries amounts of dust, causes ventilation system high concentration powder dust pollution.
The utility model content
The utility model technical problem to be solved is, a kind of drop shaft dust Control mechanism is provided, and realizes air-flow closed circulation in the mutual pressure release of drop shaft and the system, controls the purpose that dust-contained airflow sprays to reach.
In order to solve this technical problem, the utility model adopts following technical scheme:
A kind of drop shaft dust Control mechanism; The mine chute and the barren rock drop shaft that comprise setting parallel to each other; Also comprise several highly different stage casings; A diversion drop shaft and the mine chute UNICOM of each stage casing through being positioned at below, this stage casing; Through being positioned at another diversion drop shaft and the barren rock drop shaft UNICOM of below, this stage casing, it is characterized in that: below each stage casing, be provided with a contact and wear near position with the fork drop shaft of this stage casing UNICOM, the two ends that said contact is worn respectively with mine chute and barren rock drop shaft UNICOM.
Perforation place at each stage casing and diversion drop shaft is provided with electronic cover plate.
Also comprise the air inducing dedusting mechanism that communicates with mine chute or barren rock drop shaft.
The good effect of the utility model is:
The utility model each bottom, stage casing crotch between two drop shafts is provided with contact and wears, and two drop shafts is connected each other, each other the pressure release well.During drop shaft system ore drawing; The air in falling direction the place ahead of ore is by sharply compression (zone of positive pressure); Produce impact wind pressure; Because two drop shafts wear pressure release well each other through contact, impact the distinguished and admirable overwhelming majority through " mine chute-contact wear-barren rock drop shaft-contact wear-mine chute " so annular wind path, make the internal system closed circulation of dirty wind in mine chute and barren rock drop shaft formation; Thereby the dust-laden of ejection that has significantly reduced each stage casing diversion drop shaft well head is distinguished and admirable, reduces the pollution of dust to ventilation system.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Further specify the utility model below in conjunction with the accompanying drawing and the specific embodiment.
Like Fig. 1, this mechanism comprises the mine chute 1 and barren rock drop shaft 2 of setting parallel to each other, also comprises several highly different stage casings 5.The diversion drop shaft 4 and mine chute 1 UNICOM of each stage casing 5 through being positioned at these 5 belows, stage casing is through being positioned at another diversion drop shaft 4 and barren rock drop shaft 2 UNICOMs of these 5 belows, stage casing.
Below each stage casing 5, be provided with a contact and wear 3 near position with the fork drop shaft 4 of these stage casing 5 UNICOMs, said contact wear 3 two ends respectively with mine chute 1 and barren rock drop shaft 2 UNICOMs.
Closed circulation for dust air-flow in the realization system; Avoid of impact and the pollution of dust air-flow to the stage casing; Perforation place at each stage casing 5 and diversion drop shaft 4 is provided with electronic cover plate; When mine chute 1 or barren rock drop shaft 2 ore drawings (ore or barren rock), the electronic cover plate at non-ore drawing place is in closed condition, make dust-containing air stream mine chute 1, contact wear 3 and the closed system that constitutes of barren rock drop shaft 2 in circulate.
For further control dust-contained airflow ejection, also be provided with the air inducing dedusting mechanism that communicates with mine chute 1 or barren rock drop shaft 2.
Claims (3)
1. drop shaft dust Control mechanism; The mine chute (1) and the barren rock drop shaft (2) that comprise setting parallel to each other; Also comprise highly different several stage casings (5); Each stage casing (5) is through being positioned at a diversion drop shaft (4) and mine chute (1) UNICOM of below, this stage casing (5); Another diversion drop shaft (4) and barren rock drop shaft (2) UNICOM through being positioned at this stage casing (5) below is characterized in that: be provided with a contact in the below of each stage casing (5) near position and wear (3) with the fork drop shaft (4) of this stage casing (5) UNICOM, the two ends that (3) are worn in said contact respectively with mine chute (1) and barren rock drop shaft (2) UNICOM.
2. drop shaft dust Control as claimed in claim 1 mechanism is characterized in that: perforation place at each stage casing (5) and diversion drop shaft (4) is provided with electronic cover plate.
3. according to claim 1 or claim 2 drop shaft dust Control mechanism is characterized in that: also comprise the air inducing dedusting mechanism that communicates with mine chute (1) or barren rock drop shaft (2).
