Abstract
The utility model relates to fan equipment, particularly a mining pneumatic draw-out type local fan suitable for mine digging working surfaces and branch tunnels. According to the mining pneumatic draw-out type local fan provided by the utility model, in order to lower noise, silencing cotton is added to the main case, a front and back silencers are respectively arranged at the front and back ends of the main case, and a wire mesh is used instead of a punched plate; and in order to enhance the air quantity and pressure, twisted blades are adopted. The measures above greatly lower the noise of the fan, and enhance the air quantity and pressure of the fan.
Description
Technical field
The utility model relates to ventilation equipment, particularly a kind of mine pneumatic extraction type local ventilator that is applicable in mine excavation working surface and the tunnel.
Background technique
At present, there are two defectives in the pneumatic extraction type local ventilator that use in existing mine excavation working surface and a tunnel, and the one, noise is large, because silencer is not installed, noise is much larger than 85db during its work; Air quantity is little, and existing pneumatic extraction type local ventilator air quantity is 100 cubes of per minutes, and pressure is 800Pa, and air quantity is little, pressure is low.
The model utility content
The purpose of this utility model is to provide the mine pneumatic that a kind of noise is little, air quantity is large extraction type local ventilator.
The purpose of this utility model is achieved through the following channels: a kind of mine pneumatic extraction type local ventilator, it comprises wind collecting unit, blade, pneumatic motor, air inlet pipeline, main case, gas exhaust piping, straightener(stator) blade, be separately installed with premuffler and rear muffler in the outside, main case front end and back end, described blade is the curving machine airfoil fan.
As the further optimization of scheme, be coated with silencing cotton on the stage casing shell of described main case.
As the further optimization of scheme, the inwall of described premuffler and rear muffler is steel wire.
The utility model mine pneumatic extraction type local ventilator, aspect noise reduction, main case has increased silencing cotton in this programme, designed forward and backward silencing apparatus in the main case front end and back end, and replaced punched-plate with steel wire, aspect raising air quantity and pressure, adopted the meander configuration blade, by taking above-mentioned measure, greatly reduce the noise of blower fan, improved air quantity and the pressure of blower fan.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Among the figure, 1-wind collecting unit, 2-premuffler, 3-blade, 4-pneumatic motor, 5-air inlet pipeline, 6-main case, 7-rear muffler, 8-gas exhaust piping, 9-straightener(stator) blade, 10-silencing cotton, 11-steel wire 11.
Embodiment
As shown in Figure 1, the utility model mine pneumatic extraction type local ventilator, it comprises wind collecting unit 1, blade 3, pneumatic motor 4, air inlet pipeline 5, main case 6, gas exhaust piping 8, straightener(stator) blade 9, shell is coated with silencing cotton 10 in the stage casing of main case 6, the outside, main case 6 front end and back end is separately installed with premuffler 2 and rear muffler 7, the inwall of premuffler 2 and rear muffler 7 has replaced punched-plate of the prior art with steel wire 11, and described blade 3 is the curving machine airfoil fan.
During work, the down-hole wind regime drives the rotation of pneumatic motor 4 axles behind air inlet pipeline 5, discharges with the gas exhaust piping 8 of pneumatic motor 4 afterwards.Pneumatic motor 4 band moving vanes 3 rotations of rotation, the wind that the blade disturbance of High Rotation Speed is come in by wind collecting unit 1, premuffler 2 is along straightener(stator) blade 9, rear muffler 7 ejaculations of 6 li of main cases.
