Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
In the figure:
1-arc chute, 11-fixed chute; 12-a movable discharge outlet; 2-a feeding belt, 3-a discharging belt and 4-a fixed shaft; 5-a viewing port; 6. an anti-blocking monitoring probe; 7. a lifting rope.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
example 1:
the embodiment is suitable for materials such as coke, sintered ore and the like, is not suitable for wet lump ore with high viscosity and easy material adhesion, and is also not suitable for materials with better fluidity such as pellet ore and the like; (there is no concept of chutes and movable discharge outlets, mentioned at the back)
As shown in the attached figure 1, the utility model provides a dust suppression, breakage prevention and blockage prevention transfer chute, which comprises an arc chute 1, wherein the top inlet of the arc chute 1 is connected with a horizontal feeding belt 2, and the bottom outlet is connected with a horizontal discharging belt 3; arc chute 1 is equipped with two opposite arc curved sections of orientation, comes the effectual falling speed that slows down the material, reduces raise dust and to the destruction of material granularity, has improved the production greatly and has brought the circumstances of environmental protection and material quality reduction. However, the reduction of the falling speed of the material may inevitably cause blanking blockage, and therefore, an inclination angle α of the second arc-shaped curved section of the arc-shaped chute is designed according to +5 ° of a repose angle of the material (a maximum angle at which the bulk material can be stacked in a natural stable state, which is called a "repose angle"), so as to prevent the material blockage; preferably, the tilt angle a is 50 °.
Preferably, the arc chute 1 comprises a fixed chute 11 and a movable discharge opening 12, the tail end of the S-shaped fixed chute 11 is connected with the movable discharge opening 12 through a fixed shaft 4, a lifting rope 7 is bound on the movable discharge opening 12, and the angle between the movable discharge opening 12 and the ground can be adjusted by loosening or tightening the lifting rope 7; when the lifting rope 7 is loosened, the angle of the fixed chute is consistent with that of the movable discharge opening.
Preferably, the discharge opening of the movable discharge opening 12 forms an included angle of 50 degrees with the ground. Since there is a possibility of material leakage at the gap between the end of the fixed chute 11 and the movable discharge opening 12, the bottom of the movable discharge opening extends upward longer than the fixed chute to prevent material scattering.
Preferably, wear-resistant lining plates are arranged on the parts, which are contacted with materials, in the arc chute 1, so that the service life of the arc chute 1 is prolonged.
In addition, a plurality of observation ports 5 are arranged on the side wall of the arc chute 1 aiming at the position which is easy to block inside, so that the blocking materials can be treated in time; the first observation port 5 is arranged at the first arc-shaped bent section of the arc-shaped chute 1 and is a blanking point of the feeding belt, and materials are easy to accumulate at the position because the materials are turned along the arc-shaped slope of the arc-shaped chute 1 after being blanked at the position; in order to solve the problem, an anti-blocking monitoring probe 6 is arranged below a tail wheel of a feeding belt head and is interlocked with a feeding belt 2, when blocking occurs, the material level is increased to rise to trigger a blocking monitoring device, and the feeding belt 2 stops running; the second and third observation ports are respectively arranged at two sides of the second arc-shaped bent section of the arc chute 1, so that the blanking condition of the material can be observed in time, and once accumulation occurs, the angle between the movable discharge port 12 and the ground can be adjusted by the accessible, or the accumulated material can be dredged by manual dredging.
Example 2
The embodiment is suitable for materials with good fluidity and small repose angle, such as pellet ore; this example differs from example 1 in that: when the pellet ore is fed, the discharge hole of the fixed chute 11 is tensioned upwards through the lifting rope 7, and the included angle between the discharge hole and the ground is 30-35 degrees.
Utilize technical scheme, or technical staff in the field be in the utility model technical scheme's inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
