Abstract
The invention discloses a fan, belonging to the technical field of ventilation equipment. The fan comprises a shell and a motor mounted in the shell, wherein the shell corresponding to two ends of the motor is provided with two air inlets; an output shaft of the motor extends to two ends, each of which is provided with a fan blade in a sleeving way by an impeller, the lower end of an outer wall of the motor is provided with two opposite wind boards, and the shell corresponding to the lower end of the motor is provided with an air outlet. By adopting the fan, the problems that an existing fan is inconvenient to mount in a mine shaft and is low in air draft efficiency are solved.
Description
Technical field
The present invention relates to ventilation equipment technical field, especially a kind of blower fan for taking a breath.
Background technique
Blower fan is that the mechanical energy rotated is converted to gas pressure energy and kinetic energy, and the machinery that gas is transferred out.A kind of blower fan comprises the casing that offers an intake grill and an exhaust outlet and is arranged in casing the impeller be sleeved on motor one-way output shaft; Due to this blower fan only there is an intake grill and exhaust outlet wind direction constant, therefore when this assembling is in multichannel mine, one Fans is often installed and will increases a pipeline in tunnel, not only increase installation cost, waste time and energy, and single head blower fan is not because intake grill stops have axial wind to enter, define constant impact force, must have reverse restraint, this power is provided by the frictional force in blower fan, can bearing heating be caused, thus reduce air suction efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of blower fan of two-way air intake, and this blower fan can solve existing blower fan in mine, install inconvenience, the problem that air suction efficiency is low.
In order to solve the problem, the technical solution adopted in the present invention is: this blower fan, includes housing and is installed on the motor in described housing, the described housing corresponding to described motor two ends offers respectively two intake grills; Described motor output shaft stretches out to two ends, and the two ends of this output shaft is all equipped with fan blade by impeller set, and described motor outer wall lower end is provided with 2 relative wind deflectors, and the housing corresponding to described motor lower end offers exhaust outlet.
In technique scheme, technological scheme can also be more specifically: be provided with between the outer wall upper end of described motor and housing every flow, and described motor is connected with housing by link.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, mine triple channel intersection can be arranged on because blower fan has 2 intake grills, reduce and install and cost of material.
2, because motor two respectively drives a mirror image blower fan, axial wind impact force is just offset, and motor and blower interior do not have frictional force, so efficiency is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Blower fan shown in Fig. 1, the motor 6 including housing 2 and be connected with housing by link 5, the housing 2 corresponding to motor 6 two ends offers respectively intake grill 2a and intake grill 2b, the housing 2 corresponding to motor 6 lower end offers an exhaust outlet 2c; The output shaft of motor 6 stretches out to two ends, and the two ends of this output shaft is all set with impeller 3, and impeller 3 is all provided with fan blade 7, and motor 6 outer wall lower end is provided with 2 relative wind deflectors 9, is provided with every flow 4 between the outer wall upper end of motor 6 and housing.
During work, the provided with blades moving air flow at electric machine rotation motor two ends enters from the intake grill at housing two ends respectively, and due to the obstruct every flow 4, air-flow flows downward from the left chamber in housing and right chamber respectively, and passes through the effect of wind deflector 9, and air-flow flows out from exhaust outlet; Because motor two respectively drives a mirror image blower fan, axial wind impact force is just offset, and motor and blower interior do not have frictional force, so efficiency is higher.
Claims (2)
