Abstract
The utility model provides a local fan blower for a mine, which overcomes the disadvantages of a prior fan blower that whole parts are not reasonable, the flowing loss is bigger, the stationarity of impellers is not enough, thereby leading the efficiency of a fan not to be high. The local fan blower comprises parts which are a current collector, an impeller I, an impeller II, a motor and a rectifier gate which are arranged in a main wind cylinder, the impeller I and the impeller II are respectively arranged on output shafts on the two ends of the motor, blades and hubs are injected into an integrated body, and the rectifier gate is welded in a wind outlet cylinder. The local fan blower for the mine uses modified plastics to inject the materials of the impeller I and the impeller II to an integrated body shape. The impellers have consistency, smooth and flat surface, excellent gas mobility, and play the characteristics of high wind pressure, large flow, high efficiency, low energy consumption, low cost and low noise.
Description
Technical field
The utility model belongs to all kinds of mine engineering construction such as metallurgy, non-ferrous metal, chemical industry, building materials local ventilation air regenerating device technical field, specifically a kind of special-purpose ventilator that is used for the excavation ventilation of all size number, the ventilation of bottom-column-free sectional mining process route and underground engineering construction.
Background technique
The mining partial ventilating fan has obtained general use, but since whole each parts inadequately rationally, flow losses exist more greatly, the impeller stationarity is not enough, cause fan efficiency not high.Therefore how guaranteeing fan performance and raising the efficiency is the difficult problem of blower fan manufacturing.
Summary of the invention
The utility model purpose provides a kind of mining partial ventilating fan, and overcoming present blower fan, whole each parts inadequately rationally, flow losses are not enough in, impeller stationarity greatly, cause the not high enough drawback of fan efficiency.
The mining partial ventilating fan, it comprises slip ring, impeller I, impeller II, motor, all parts of honeycomb, and these parts are positioned at main wind tube; Impeller I, impeller II are installed on the output shaft of motor two ends respectively and blade and wheel hub tube form one, and honeycomb is welded in the wind outlet barrel.
Main wind tube is circular, and slip ring is a toroidal; Wind outlet barrel is circular for extending.
The utility model mining partial ventilating fan adopts impeller I, impeller II material modified plastics, is injection molded into whole shape.Impeller has conformity smooth surface, smooth, makes gas fluidity good, brings into play the characteristics of its high blast, big flow, high efficiency, low energy consumption, low cost, low noise.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is a blade wheel structure schematic representation in the utility model.
Embodiment
As shown in Figure 1, the good equipment of ventilation that the mining partial ventilating fan is made up of parts such as slip ring 1, main wind tube 4, impeller I3, impeller II6, honeycombs 7, and these parts are positioned at the casing group; Slip ring is connected on main wind tube 4 entrance points, makes the air-flow uniform and stable enter draught fan impeller, and impeller I, impeller II are installed in the axle two ends of motor 5 respectively, and wind outlet barrel 8 is connected casing rear end, honeycomb 7 is welded in wind outlet barrel 8 cylinders.Fairshaped honeycomb can make the interior smoothness of blower fan be optimized after the impeller rotation work done, improves the operational efficiency of blower fan, reduces the noise of blower fan.Protective net 2 is installed on the wind outlet barrel 8 and before being positioned at slip ring 1.
The blower fan outward appearance designs for cylindrical body, slip ring is a toroidal, main wind tube is circular, wind outlet barrel is circular for extending. and air communication is crossed the impeller I that the fusiform slip ring uniform and stable of loudspeaker enters blower fan, impeller II, after the impeller rotation work done, through honeycomb the interior smoothness of blower fan is optimized, when obtaining guiding straightening circumferencial direction speed air quantity, promptly made the impact of air-flow in order, increased the energy of air-flow, it is good to make blower fan reach gas fluidity, the efficient height, noise is low, the effect that air supplying distance is far away. it is good that this blower fan has a gas fluidity, energy-conservation, the efficient height, low noise, air supplying distance is far away, compact structure, install, characteristics such as convenient transportation.
As shown in Figure 2, the mining partial fan impeller is to adopt modified plastics that two of 2-1,2-2 are injection molded into the one impeller, has flame retardant property and anti-static electricity property.Because integral molded plastic moulding, impeller has conformity, and smooth surface is smooth, makes gas fluidity good, bringing into play the characteristics that its high blast, big flow, high efficiency, low energy consumption, low cost, low noise, blade do not rupture, is the desirable equipment of all kinds of mining partial construction ventilations ventilations.
The utility model mining partial ventilating fan has been determined blower fan blade profile, cylindrical shape wheel hub by model investigation, adopts modified plastics to be injection molded into integral wheel.After improving, reduced flow losses, thereby made gas fluidity good, fan efficiency improves 90%, and noise has reduced 3.8dB than A sound, has strengthened blade strength again, has guaranteed that blower fan is firm and running is steady, durable.
This blower fan adopts the three-dimensional flow optimal design according to fluid mechanics principle, uses airfoil blade.Adopt bilobed wheel to form the rotating boosting mode, further improved the working efficiency of blower fan.This blower fan has been broken through several guardian technique difficult problems in the research and development field, we can say; Once huge innovation in the mine ventilator field.
A wind outward appearance is a cylindrical design, and main wind tube is circular, can make air-flow smooth along rotating work done by impeller.Slip ring is a horn shape, can make the smooth suction gas of air-flow.Honeycomb is that the streamlined interior smoothness of blower fan that makes is optimized, and improves the operational efficiency of blower fan, the noise of reduction blower fan.Really be the optimal ventilation equipment in all kinds of excavation engineering constructions.
This blower fan is the model utility product that design research and development for metallurgical I, all kinds of mine engineerings constructions such as coloured gold, chemical industry, building materials, ventilates and the smooth digging of underground engineering is constructed reliable guarantee is provided at all size section excavation ventilation, bottom-column-free sectional mining process route.
