Abstract
The utility model discloses an anti-reflux air distributor which comprises a shell (1). Two air inlets (2) positioned in the same direction are arranged on one side of the shell (1), an air outlet (3) is arranged on the other side of the shell (1), the two air inlets (2) are communicated with the air outlet (3) through the shell (1), and anti-reflux devices (4) are arranged on the inner sides of the two air inlets (2). As the anti-reflux devices are arranged on the inner side of the air distributor, reflux can be prevented when a fan falls, air flow is 'switched', effective, safe and continuous air supply can be ensured when the fan falls, and safety production of a driving face is ensured. As the shell is made of metal, the service life of the shell can be ensured, the problem of air leakage is avoided, and use safety and stability are improved. Besides, the anti-reflux air distributor is simple in structure and fine in use effect.
Description
Technical field
The utility model relates to a kind of coal mine machinery field, especially a kind of air devider that prevents adverse current.
Background technology
In coal production, in order to guarantee the safety in production of mine, better carry out trouble free service, mine need to be carried out ventilation, the mode Gas Outburst.Local ventilation is the important component part of mine ventilation, and the management of local ventilation simultaneously is the emphasis of mine ventilation.The local ventilation place is hazardous location, if partial Ventilation Management is not good at causing that easily gas, mine dust gather etc., even can cause gas explosion, coal-dust explosion etc., brings threat for business property and employee's life.Therefore, the management of research local ventilation is particularly important.But also have certain difficulty in actual production process in partial Ventilation Management work, often automatically fall from power experiment with the damage of blower fan air devider because of blower fan, cause the driving face blowing-out, cause methane accumulation or transfinite.Thereby increased the labour intensity, waste material, labour cost of logical anti-work etc., and caused serious potential safety hazard.
Summary of the invention
The purpose of this utility model is: a kind of air devider that prevents adverse current is provided, and it can when blower fan is fallen from power, prevent anti-reverse, play " switching " distinguished and admirable effect, the continuous air feed of effective and safe of falling from power in the time of can guaranteeing blower fan has been guaranteed the safety in production of driving face, to overcome the deficiencies in the prior art.
The utility model is achieved in that the air devider that prevents adverse current, comprise shell body, a side at shell body is provided with two air intakes that are in equidirectional, is provided with an air outlet at the opposite side of shell body, is communicated with by shell body between two air intakes and air outlet; Inboard at two air intakes is equipped with anti-backflow device.
Described anti-backflow device comprises fixed axis, and the two ends of fixed axis are fixed on the inboard of air intake, is provided with two fan blades on fixed axis, and the diameter of fan blade is greater than the diameter of air intake.
Shell body is the metal shell body.The intensity of metal shell body is better, can solve the air devider shell body fragile and cause the problem of leaking out, and has guaranteed the wind supply quantity of driving face.
One of them air intake and air outlet are on same straight line, and the shell body that another air intake is corresponding is circular arc.Such structure can reduce fan resistance when air-supply, improve air-supply efficient.
Owing to having adopted technique scheme, compared with prior art, the utility model adopts the structure of anti-backflow device is set in the inboard of air devider, make it can be when blower fan is fallen from power, prevent anti-reverse, play " switching " distinguished and admirable effect, the continuous air feed of effective and safe of falling from power in the time of can guaranteeing blower fan has been guaranteed the safety in production of driving face; Because shell body adopts the metal shell body, therefore can guarantee application life, avoid the problem of leaking out, improve the safety and stability that uses.The utility model is simple in structure, and result of use is good.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the outer structural representation of filter box of the present utility model.
The specific embodiment
Embodiment of the present utility model: prevent adverse current air devider structure as shown in Figure 1, comprise the shell body 1 that adopts the thick steel plate of 3mm to be processed into, a side at shell body 1 is provided with two air intakes 2 that are in equidirectional, opposite side at shell body 1 is provided with an air outlet 3, one of them air intake 2 and air outlet 3 are on same straight line, the shell body 1 of another air intake 2 correspondences is circular arc, is communicated with by shell body 1 between two air intakes 2 and air outlet 3; Be equipped with anti-backflow device 4 in the inboard of two air intakes 2; Described anti-backflow device 4 comprises fixed axis 4-1, and the two ends of fixed axis 4-1 are fixed on the inboard of air intake 2, is provided with two fan blade 4-2 on fixed axis 4-1, and the diameter of fan blade is greater than the diameter of air intake 2.
In use, the utility model is arranged on two Fans air outlets and air duct air intake junction, two air intake 2 corresponding two Fans air outlets of difference, air outlet 3 is connected with the air duct air intake, after blower fan is fallen from power automatically, the fan blade 4-2 of anti-backflow device 4 can be under the wind-force effect inboard of automatic paste tightening air intake 2, prevent that the air-flow of the blower fan that moving is from another air intake 2 adverse currents, play " switching " distinguished and admirable effect, guarantee timely and effective safe and continuous air feed.
