Abstract
The utility model discloses an auxiliary dust collecting system of a coal mine tunnel. The auxiliary dust collecting system of the coal mine tunnel comprises an air return pipe arranged along the bottom of one side of the tunnel, and more than two air return ports are evenly formed in the air return pipe at intervals. One end of the air return pipe is closed, and the other end of the air return pipe is an air outlet end and is connected with a dust collecting pipeline. An active carbon absorbing device, a filter device and an axial flow fan are arranged on the dust collecting pipeline in series in sequence in the flow direction of air inside the pipeline, and a blast pipe is connected at the tail end of the dust collecting pipeline. The ventilation direction inside the pipeline is regarded as the front direction, and the blast pipe is arranged in front of the air return pipe and on the top of the tunnel. More than two air outlets are evenly formed in the blast pipe. The auxiliary dust collecting system of the coal mine tunnel is simple in structure and convenient to manufacture and use, can compensate for the deficiency of an existing ventilation system in a mine, can be arranged in any tunnel sections needing auxiliary dust collection, and enables the working environment in the mine to be more clean and comfortable.
Description
Technical field
The utility model relates to a kind of coalmine ventilation technical field, especially a kind of dust pelletizing system.
Background technology
At present, under the ore deposit, ventilation equipment adopt mechanical forced ventilation equipment, with the production tunnel as air intake passage.Existing ventilation equipment are the supporting dust arrester that is provided with all, guarantees to carry the gas of cleaning in the tunnel.But can produce a large amount of dusts in coal mine roadway driving and seam mining process, existing dust arrester is difficult to avoid dust to enter the tunnel fully, and when in the tunnel, transportation goods and materials and personnel are current, also can produce at any time new dust, cause occurring sometimes dust along the situation of tunnel diffusion, affect normal operating environment.
The utility model content
The purpose of this utility model is to provide a kind of coal mine roadway assisted dust-collecting system.
For achieving the above object, coal mine roadway assisted dust-collecting of the present utility model system comprises the backwind tube that one side bottom arranges along the tunnel, evenly is interval with two above return air inlets on backwind tube; Backwind tube one end sealing, the other end of backwind tube is outlet air end and is connected with the dedusting pipeline; Along the flow direction of wind in pipeline, to connect successively on the dedusting pipeline and be provided with activated carbon adsorption unit, filter and axial flow blower, the end of dedusting pipeline is connected with ajutage; Direction of ventilation in the tunnel is as forward direction, and described ajutage is arranged on the top, tunnel in backwind tube the place ahead; Evenly be provided with two above air outlets on ajutage.
Described backwind tube blind end is provided with internal thread and is bolted with plug, and described backwind tube outlet air end and described backwind tube blind end are complementary and are provided with external screw thread.
Described each air outlet all tilts towards the front lower place.
During use, the backwind tube in the utility model is laid in a side bottom that produces the more tunnel section of dust.As required, can will be screwed onto together before and after the more piece backwind tube in order to be combined into the length that needs.Certainly, also a plurality of the utility model alternately can be laid along the tunnel, with the long dedusting scope in edge.When laying backwind tube, the ajutage in the utility model is laid in adjacent section top, tunnel, backwind tube the place ahead.When in tunnel section corresponding to the utility model, dust is larger, start axial flow blower, the wind the tunnel in is extracted out by the bottom, and device filters afterwards and is sent by the top, tunnel after filtration, thereby dust removal operation is carried out in this section tunnel, has made up the deficiency of ventilation system under existing ore deposit.Due to the utility model return air inlet under, air outlet is upper, therefore can not produce air-flow from bottom to top, avoids the dust of Near Ground is blowed to eminence.The setting of activated carbon adsorption unit can alleviate the burden of filter.
In a word, the utility model is simple in structure, is convenient to make and uses, and can make up the deficiency of ventilation system under existing ore deposit, and can be arranged in needs arbitrarily in the section of the tunnel of assisted dust-collecting, makes that under the ore deposit, working environment more cleans, comfortable.
Description of drawings
Fig. 1 is that the utility model is arranged on the structural representation in the tunnel.
The specific embodiment
In Fig. 1, direction shown in arrow is normal direction of ventilation in the tunnel.
As shown in Figure 1, coal mine roadway assisted dust-collecting of the present utility model system comprises the backwind tube 1 that one side bottom arranges along the tunnel, evenly is interval with two above return air inlets 2 on backwind tube 1; Backwind tube 1 one end sealings, the other end of backwind tube 1 is outlet air end and is connected with dedusting pipeline 3.
Along the flow direction of wind in pipeline, to connect successively on dedusting pipeline 3 and be provided with activated carbon adsorption unit 4, filter 5 and axial flow blower 6, the end of dedusting pipeline 3 is connected with ajutage 7.Dedusting pipeline 3, activated carbon adsorption unit 4, filter 5 and axial flow blower 6 all preferred concealed installation on the sidewall of tunnel.Filter 5 can adopt various existing strainers, is this area routine techniques, its structure is not done concrete the restriction herein.
Direction of ventilation in the tunnel is as forward direction, and described ajutage 7 is arranged on the top, tunnel in backwind tube 1 the place ahead; Evenly be provided with two above air outlets 8 on ajutage 7, each air outlet 8 all tilts towards the front lower place.
For ease of making, transport and install, preferred long 1.5 meters to 3 meters of backwind tube 1 of the present utility model.Described backwind tube 1 blind end is provided with internal thread and is bolted with plug 9, and the blind end of the outlet air end of described backwind tube 1 and described backwind tube 1 is complementary and is provided with external screw thread.Such setting, can be in tunnel under the ore deposit as required, plural backwind tube 1 front and back are connected to be screwed onto together, thereby is combined into the backwind tube of random length according to actual conditions under the ore deposit, makes backwind tube of the present utility model can satisfy the dedusting needs of different length tunnel section.
During use, the backwind tube 1 in the utility model is laid in a side bottom that produces the more tunnel section of dust.As required, more piece backwind tube 1 front and back can be screwed onto together in order to be combined into the length that needs.Certainly, also a plurality of the utility model alternately can be laid along the tunnel, with the long dedusting scope in edge.When laying backwind tube 1, the ajutage 7 in the utility model is laid in adjacent section top, tunnel, backwind tube 1 the place ahead.When dust is larger in tunnel of the present utility model section is installed, start axial flow blower 6, the wind in the tunnel is extracted out by the bottom, installs after filtration 5 filtrations and is sent by the top, tunnel afterwards, thereby dust removal operation is carried out in this section tunnel, made up the deficiency of ventilation system under existing ore deposit.Due to the utility model return air inlet 2 under, air outlet 8 is upper, therefore can not produce air-flow from bottom to top, avoids the dust of Near Ground is blowed to eminence.
