Abstract
The utility model discloses a dust exhausting fan is with a suction tube of waiting to inhale speed cambered surface inlet scoop, it joins in marriage the dress on dust exhausting fan (8) air intake, suction tube (3) main aspects are the flat arris toper, be provided with aspiration channel (4) about suction tube's the tip relatively, the aspiration channel links to each other with negative-pressure air pipe (2) one end activity, and negative-pressure air pipe other end swing joint has leading inlet scoop (1), suction tube main aspects terminal surface is dust absorption cambered surface (7). The utility model discloses not only increased the area of induced drafting, enlarged the degree of depth of induced drafting, increased the dirty gas volume of induced drafting, can be favorable to improving dust collection effect according to the position of the leading inlet scoop of condition adjustment moreover. The utility model discloses compact structure, dismouting maintenance convenience do not occupy ground and space, can not influence other construction operations.
Description
Technical Field
The utility model relates to a suction tube especially relates to a suction tube of equiping on the dust exhausting fan that the mine used and inhale speed cambered surface inlet scoop equally.
Background
When a tunnel is tunneled under a coal mine, due to the fact that air circulation of a tunneling working face is not smooth, a large amount of dust can be generated in the tunneling process of the tunneling machine and float in the air for a long time, the dust concentration in the air on the tunneling working face is high, and a dust removal fan with an air suction barrel needs to be arranged on the tunneling working face for removing dust. The air suction inlet of the existing air suction barrel is a plane, and as a result, the central air speed of the plane of the air suction inlet is high, and the air speed is obviously reduced near the edge of the air suction inlet, so that the dust suction effect is poor. Moreover, although the air suction barrel is designed with a flaring, the area of the air suction opening is still not large, dust is easy to diffuse to the rear of the working surface, the dust content in the rear air is too large, the physical and mental health of workers is seriously affected, and the life risk can be caused even in the environment with high dust concentration after long-time working.
SUMMERY OF THE UTILITY MODEL
To the problem that dust exhausting fan dust catcher exists among the above-mentioned prior art, the utility model provides a take leading inlet scoop, not only can take out alone dismantlement, durable, and can improve dust exhausting fan dust collection efficiency's dust collection fan greatly with the suction tube of waiting to inhale speed cambered surface inlet scoop.
The to-be-solved technical problem of the utility model is that: a dust suction cylinder with a cambered surface air suction opening with equal suction rate for a dust removal fan is assembled on an air inlet of the dust removal fan, the large end of the dust suction cylinder is in a flat flared pyramid shape, negative pressure air pipes are oppositely arranged on the left and right sides of the small end of the dust suction cylinder, the negative pressure air pipes are movably connected with one end of the air suction cylinder, the other end of each negative pressure air pipe is movably connected with a front air suction opening, and the end face of the large end of the dust suction cylinder is a dust suction cambered surface.
Furthermore, two ends of the negative pressure air pipe are respectively movably connected with the air suction pipe and the front air inlet through loose joint pipe sleeves, and the negative pressure air pipe is made of a telescopic pipe.
The utility model discloses owing to change the plane inlet scoop of current suction tube into cambered surface inlet scoop, enable like this to induced draft on the face of induced drafting and be the constant speed and induced draft, make the flow direction of induced drafting on the terminal surface of induced drafting orderly, the volume of induced drafting is even. Because the arc area is larger than the plane area, the air suction volume is increased. In addition, the two sides of the dust suction cylinder are provided with the front-arranged air suction openings with position adjustment, so that the air suction area is increased, the air suction depth is enlarged, the air suction volume of the dust-containing air is increased, the position of the front-arranged air suction opening can be adjusted according to the condition, and the dust suction effect is improved. The utility model discloses compact structure, dismouting maintenance convenience do not occupy ground and space, can not influence other construction operations.

Figure 1 is a schematic view of the structure of the utility model,
fig. 2 is a left side view structure diagram of the present invention.
In the figure, 1, a front air suction opening 2, a negative pressure air pipe 3, a dust suction barrel 4, an air suction pipe 5, a connecting seat 6, a flange 7, a dust suction cambered surface 8, a dust removal fan 9 and a loose joint pipe sleeve.
Detailed Description
In the figure, a dust suction tube with a constant suction rate cambered surface air suction opening for a dust removal fan is assembled on an air inlet of a dust removal fan 8, the small end of the dust suction tube 3 with the constant suction rate cambered surface air suction opening is a connecting seat 5 (formed by intersecting a round hole on the dust removal fan with a flat square hole on the dust suction tube), the large end of the dust suction tube is in a flat square pyramid shape, the connecting seat is connected with the air inlet of the dust removal fan 8 through a flange 6, a rubber pad and a screw, air suction tubes 4 are oppositely arranged on the left and the right of the small end of the dust suction tube, the air suction tubes are movably connected with one ends of negative pressure air tubes 2 through a movable connecting tube sleeve 9, the other ends of the negative pressure air tubes are movably connected with a front air suction opening 1 through a movable connecting tube sleeve 9, the large end surface (flat square pyramid end surface) of the dust suction tube is a. Two ends of the front-mounted air suction opening can be expanded outwards or contracted inwards so as to be beneficial to sucking dust-containing air on a working surface.
The foregoing description is a more detailed description of the invention, taken in conjunction with the specific preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described above. To those skilled in the art to which the present invention pertains, the changes or substitutions made without departing from the principles and concepts of the present invention should be considered as belonging to the protection scope of the present invention.
