Abstract
The utility model discloses an axial flow fan which is high in intensity of fan blades, small in noise, excellent in performance, easy to mount, operate and use, and convenient to maintain. The axial flow fan is composed of a base, an impeller, a mounting base, a hydraulic motor, a front flow guide device, a flow collector and a streamline cover. The streamline cover and the base are connected through a bolt, and the flow collector is of a circular-arc-shaped structure. The impeller is composed of a hub and plastic vanes, each vane is of a structure with the cross section being in a wing shape, and the vanes are embedded on the steel hub. The hub and the plastic vanes are fastened through bolts, and the two end faces of the hub are covered with copper sheets. The hydraulic motor is mounted in a core tube and is connected with the impeller of the fan through a coupling.
Description
Affiliated technical field
The utility model relates to a kind of ventilation plant of industrial and mining enterprise, the propeller fan that especially noise is few, drafting efficiency is high.
Background technique
Axial-flow blower is again booster, is the conventional a kind of blower fans of industrial and mining enterprise, but is different from general blower fan, and its motor and fan blade are all in a cylinder, and profile is exactly a tubular, and for local ventilation, the cylinder of can giving a dinner for a visitor from afar is kept watch and delivered to the region of appointment.
At present, in the construction work of industrial and mining enterprise, in order to water down and get rid of harmful gas and the dust in mine, ensure that underground work personnel have sufficient amount, satisfactory air for breathing, improve underground work environment, must supply with incessantly in process of production a large amount of fresh airs.The every conveying 4～6t of normal conditions fresh air, the power consumption of mine main ventilator on average accounts for 8 %～15 % of total power consumption.The increase to energy demand along with energy shortage in world wide and economic growth, an urgent demand people energy saving and protection of the environment.Mine main ventilator all must move every day, selects economize on electricity, low noise type ventilator just to seem extremely important.And in the axial-flow blower main product using at present, compared with the Fan Product of the blower fan of home brands and the same nominal aerodynamic parameter of foreign brand name or import, mainly there is following gap: 1. overall efficiency is on the low side, energy consumption is higher; 2. fan performance curve is steeper, adapts to the ability of variable working condition; 3. total noise of centrifuge is higher.
Summary of the invention
In order to overcome the deficiency that existing air-blower noise is large, overall efficiency is on the low side, the utility model provides a kind of propeller fan, and not only fan blade intensity is high, noise is few for this propeller fan, and function admirable, fitting operation are used simple, easy to maintenance.
The utility model solves the technological scheme that its technical problem adopts: a kind of propeller fan, be made up of pedestal, impeller, mounting base, oil hydraulic motor, preposition fluid director, slip ring, streamlined windscreen seven parts, described streamlined windscreen is realized and being connected by bolt with pedestal; Described slip ring is structure in the arc-shaped; Described impeller is made up of wheel hub and plastic blade, and described blade is the structure that section becomes wing blade, and described blading is on steel wheel hub; Described wheel hub and plastic blade bolton, both ends of the surface cover with copper sheet; Described oil hydraulic motor is installed in core cylinder, and is connected with draught fan impeller by shaft coupling.
The utility model, the streamlined windscreen of propeller fan is connected with bolt with pedestal, can adjust according to the difference of operating mode the angle of streamlined windscreen and pedestal; Slip ring adopts structure in the arc-shaped, is provided with the cowling that semicircle is spherical in it, by the importing impeller of gas uniform, reduces the distinguished and admirable drag losses of entrance, thereby has increased speed and the blast of air; Impeller is made up of wheel hub and plastic blade, and blade section becomes wing blade, is embedded on steel wheel hub, and get up by bolton, both ends of the surface cover with copper sheet, not only can regulate on demand the setting angle of plastic blade, the noise having produced while also having reduced blade High Rotation Speed; Oil hydraulic motor is installed in core cylinder, and is connected with draught fan impeller by shaft coupling, the design of this structure, and the sound that while having avoided motor movement, vibrations occur, also produces dual rotary pulse jet, and projection is long.
Working principle of the present utility model: air-flow enters streamlined windscreen by slip ring, obtain pre-supination through preposition fluid director, under the effect of impeller movable vane, increase energy, thereby obtain certain speed and blast, proofread and correct after flow direction through fixing each stator again, discharge to approach axial direction.
The beneficial effects of the utility model are, can improve overall efficiency, fall the low noise while, and fitting operation uses simple, easy to maintenance, adapts to all-environment operating mode.
