Abstract
The utility model relates to a main roadway long distance whole section spraying device. A plurality of section spray nozzle groups and multiple ground spray nozzle groups are arranged along the stretching direction of the main roadway. The section spray nozzle groups are arranged on the lateral wall of the main roadway which is higher than the main roadway ground; water mist is sprayed out from the lateral direction of the section spray nozzle groups and covers the main roadway ground. Water supply for pipelines of the section spray nozzle groups and the ground spray nozzle groups comes from both ends; a control system controls the work of a spray nozzle through an electromagnetic valve. The main roadway long distance whole section spraying device has the advantages that the device adopts a multi-unit stereometric formula spraying setting method, achieves that spray mist covers a whole section, and eliminates dust in the air and dirt retention on the ground. The dedusting and dust-falling effects are obvious. Both ends of the pipeline provide water, and problems that a sprayer is far away from a valve, the sprayer water pressure is small and the atomization is not good are solved.
Description
Technical field
The utility model belongs to dust falling in coal mining equipment, relates in particular to the full section spray device of the long distance in a kind of large lane.
Background technology
Coal mine is in the production processes such as coal mining, driving, explosion, shipment, capital produces a large amount of dust, mechanization degree is higher, the dust produced is more, swimming that these dust have flowed with distinguished and admirable in the operating environment air, some gravitates form laying dust, and they can directly or indirectly produce harm to health.Mine Dust has dual harmfulness, can damage health, again violent coal-dust explosion can occur, and just can cause in a flash ore deposit to ruin the major accident that the people dies.Atomizing de-dusting can effectively prevent dust from flying and accumulation, but the pipe arrangement that arranges of shower nozzle is understood effect and the system reliability that directly affect depositing dust.
Summary of the invention
The purpose of this utility model is the technical scheme that proposes the full section spray device of the long distance in a kind of large lane, improves tunnel dust-laying effect and device functional reliability.
To achieve these goals, the technical solution of the utility model is: the full section spray device of the long distance in a kind of large lane arranges a plurality of section waterfog head groups and a plurality of surface water fog spray head group along tunnel along stretching direction; Described section waterfog head group is positioned at the tunnel sidewall higher than ground, tunnel, and section waterfog head group covers drift section from side direction ejection water smoke; Described a plurality of section waterfog head group is connected by a section pipe-line; Described surface water fog spray head group is positioned at ground, tunnel, and surface water fog spray head group upwards sprays water smoke and covers ground, tunnel; Described a plurality of surface water fog spray head group is connected by a ground pipe-line.
The inside nominal diameter of described section pipe-line is DN20, at the two ends of section pipe-line, all by electromagnetic valve, with water source, is connected, and the inside nominal diameter of described ground pipe-line is DN20, at the two ends of ground pipe-line, all by electromagnetic valve, with water source, is connected; Described electromagnetic valve is the bi-bit bi-pass normally closed solenoid valve.
Each described section waterfog head group has two single hole shower nozzles that are provided with in the vertical direction angle, and each described surface water fog spray head group has two three hole shower nozzles that are provided with angle.
The length of described section pipe-line and ground pipe-line is not more than 200 meters; Spacing between adjacent two described section waterfog head groups is 20 meters; Spacing between adjacent two described surface water fog spray head groups is 20 meters.
The beneficial effects of the utility model are: adopt the three-dimensional spraying settings of many groups, realized that full section spraying covers, can eliminate the laying dust on airborne floating dust and ground, dedusting, dust-laying effect are more obvious; Adopt the pipeline two ends to supply water, solved because shower nozzle is far away apart from valve, nozzle hydraulic is little, the atomization problem of poor.
Below in conjunction with drawings and Examples, the utility model is described in detail.
The accompanying drawing explanation
Fig. 1 is the utility model system drawing;
Fig. 2 is the utility model shower nozzle schematic views.
The specific embodiment
As shown in Figure 1, Figure 2, the full section spray device of the long distance in a kind of large lane, arrange a plurality of section waterfog head groups 1 and a plurality of surface water fog spray head group 2 along tunnel along stretching direction; Described section waterfog head group is positioned at the tunnel sidewall higher than ground, tunnel, and section waterfog head group covers drift section from side direction ejection water smoke 6; Described a plurality of section waterfog head group is connected by a section pipe-line 3; Described surface water fog spray head group is positioned at ground, tunnel, and surface water fog spray head group upwards sprays water smoke 7 and covers ground, tunnel; Described a plurality of surface water fog spray head group is connected by a ground pipe-line 4.
The inside nominal diameter of described section pipe-line is DN20, at the two ends of section pipe-line, all by electromagnetic valve, with water source, is connected, and the inside nominal diameter of described ground pipe-line is DN20, at the two ends of ground pipe-line, all by electromagnetic valve, with water source, is connected; Described electromagnetic valve is the bi-bit bi-pass normally closed solenoid valve.
Each described section waterfog head group has two single hole shower nozzles that are provided with in the vertical direction angle, and each described surface water fog spray head group has two three hole shower nozzles that are provided with angle.
The length of described section pipe-line and ground pipe-line is not more than 200 meters; Spacing between adjacent two described section waterfog head groups is 20 meters; Spacing between adjacent two described surface water fog spray head groups is 20 meters.
In a specific embodiment, the length of section pipe-line and ground pipe-line is 180 meters, and 10 section waterfog head groups are installed on the section pipe-line, and section waterfog head group is 1.8 meters apart from the height on ground, tunnel; 10 surface water fog spray head groups are installed on the pipe-line of ground.Spacing between adjacent two described section waterfog head groups is 20 meters; Spacing between adjacent two described surface water fog spray head groups is 20 meters.
