Abstract
The utility model provides a novel mine fan. The innovation point of the fan mainly lies in that a transmission mechanism is added, wherein the transmission mechanism is connected with a motor via a diaphragm coupling. Because a structure consisting of a diaphragm coupling and a transmission shaft is added, the problem that the motor is damaged due to an insufficient load bearing is solved, thereby ensuring the safe operation of the motor, and improving the stability of the whole fan. Additionally, an aerodynamic efficiency is increased, and a good energy-saving effect is acted via an installation for a twisty airfoil blade and a mechanism optimization that the installation angle of the blade is adjustable.
Description
Technical field
The utility model relates to a kind of mine and uses blower fan.
Background technique
Mine fan is specially according to metallurgy, and is coloured, gold, chemical industry; The needs design of all kinds of non-mine ventilations such as building materials and nuclear industry, can be used as main fan, auxilliary fan can be installed in the face of land; Also can be installed on the down-hole, suitable multi fan co-operation is the desirable machine station blower fan in machines at different levels station in the multi fan series and parallel multi fan station ventilation system; Also applicable between large car, tunnel, the ventilation of civil air defense constructions and installations occasion.
Blower fan commonly used at present all is motor and draught fan impeller direct connection, because the strength that draught fan impeller carries is bigger, this strength is loaded on the motor bearings blower fan, and motor bearings is often damaged in actual use.And motor one is bad, and blower fan has just quit work, thereby causes the down-hole can't ordinary production, brings bigger economic loss.
Summary of the invention
In order to solve the problem of mentioning in the background technique, prevent motor bearings owing to carrying excessive the damage, the utility model provides a kind of novel blower fan.Innovative point in this blower fan mainly is to have increased a sets of transmission mechanism, and this driving mechanism adopts diaphragm coupling to be connected with motor.This blower fan is also improved on blade structure in addition.
Specifically, the novel fan that the utility model provided is made up of motor, diaphragm coupling, transmission shaft, draught fan impeller and air duct.Motor directly links to each other with diaphragm coupling, and diaphragm coupling directly links to each other with transmission shaft, and transmission shaft links to each other with draught fan impeller.Wherein draught fan impeller adopts the distortion wing blades, improves pneumatic efficiency.The blade installation angle of blower fan is adjustable, to adapt to the variation of production demand.
The blower fan that the utility model provides can be selected two kinds of hub ratios 0.40 and 0.45.
The blower fan that the utility model provides can be selected three kinds of rotating speeds, is respectively 1450r/min, 960r/min, 730r/min.
The blower fan that the utility model provides can use by unit, also can two blower fans be merged revolving use, can also a plurality of blower fans be united to form the series parallel connection multi fan station ventilation system.
The blower fan that the utility model provides has solved motor owing to the not enough problem of damaging of carrying owing to added the structure of diaphragm coupling and transmission shaft, thereby guarantees the safe handling of motor, has improved the whole stability of blower fan.In addition, twist wing blades through installing, and the adjustable such Mechanism Optimization of blade installation angle, improved pneumatic efficiency, played good energy-saving effect.
Description of drawings
Fig. 1 is that described two blower fans of the utility model merge revolving the structural representation of use.
Wherein 1 is blower fan 1,2nd, blower fan 2,3rd, motor, the 4th, diaphragm coupling, the 5th, transmission shaft, the 6th, draught fan impeller.
Embodiment
Shown in accompanying drawing, the described blower fan of the utility model is made up of motor, diaphragm coupling, transmission shaft, draught fan impeller and air duct.Motor directly links to each other with diaphragm coupling, and diaphragm coupling directly links to each other with transmission shaft, and transmission shaft links to each other with draught fan impeller.Wherein draught fan impeller adopts the distortion wing blades, improves pneumatic efficiency.The blade installation angle of blower fan is adjustable, to adapt to the variation of production demand.
Technical parameter when following table is to use the described blower fan of the utility model, use be 2 380v, the Y355L-6 motor of 2500kw, the running state of blower fan is rotating speed 980r/min, 20 ℃ of temperature.
The preferred embodiment that the above is merely the utility model is not the protection domain that is used to limit the utility model.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
Those skilled in the art can make replacement or modification to some structures of the utility model according to disclosed content of the utility model and the art technology of being grasped; But these replacements or modification should not be regarded as breaking away from the present invention's design, and these replacements or modification are all in the utility model requires the interest field of protection.
