Technical Field

The invention relates to a large-inclination-angle belt conveyor.

Background

The maximum inclination angle of the common belt conveyor in use can not exceed 19 degrees. The large-inclination-angle belt conveyors all adopt skirt-edge belts, the skirt-edge belt main bodies are annular base bands, two fold ring edges are arranged on the annular base bands, and a plurality of vertical partition plates are arranged on the annular base bands between the two parallel fold ring edges at intervals. The belt conveyor with the structure can realize large-inclination-angle conveying. For example, the Chinese utility model with the authorization notice number CN204078741U of 015.01.07 authorization notice discloses a belt conveyor with a large inclination angle.

When the existing large-inclination-angle belt conveyor is used, pulverized coal or coal particles are often entrained in the folds on the fold annular edge of the skirt-edge belt and in included angles among the fold annular edge, the vertical partition plate and the annular base belt, the entrained pulverized coal or coal particles still partially remain along with the skirt-edge belt after passing through a discharge port, and the remaining pulverized coal or coal particles are turned into a downward state along with the skirt-edge belt and gradually fall off to the ground below a rack of the large-inclination-angle belt conveyor, so that on one hand, coal resources are wasted, and on the other hand, the site ground and air are polluted.

When the coal contains moisture with or above the moisture content, the phenomenon of entrainment of the residual coal dust or coal particles is more prominent.

Disclosure of Invention

The invention aims to solve the technical problem of how to overcome the defects in the prior art and provide a large-inclination-angle belt conveyor with less waste of coal resources and less field pollution.

For solving above-mentioned technical problem, this big inclination belt conveyor, including frame, initiative cylinder, driven cylinder and shirt rim belt, the frame includes horizontal feed section, middle slope section and ejection of compact section, and ejection of compact section is higher than horizontal feed section, horizontal feed section and ejection of compact section are connected respectively to middle slope section both ends, initiative cylinder axle dress is at horizontal feed section head end, and driven cylinder axle dress is at ejection of compact section tail end, the shirt rim belt includes the annular baseband, is equipped with two parallel fold ring limits on the annular baseband surface, and it is equipped with a plurality of perpendicular baffles still to separate on the annular baseband between two parallel fold ring limits, and the annular baseband both ends are overlapped respectively on initiative cylinder and driven cylinder, its characterized in that: the joint of the middle inclined section and the discharge section is provided with an upper corner pressing wheel and a plurality of upper bend supporting rollers, wherein the plurality of upper bend supporting rollers are fixed between the upper-layer skirt belt and the lower-layer skirt belt, and each upper bend supporting roller is respectively supported on the lower surface of the upper-layer skirt belt, so that the upper-layer skirt belt is protruded into a circular arc shape.

The upper corner rotating pressing wheel comprises a main shaft, two large pressing wheels and two small pressing wheels, the two large pressing wheels and the two small pressing wheels are fixed on the main shaft, the main shaft of the upper corner rotating pressing wheel is fixed at the head end of a discharging section of the rack, the two large pressing wheels are abutted to two sides of an annular base band of the lower-layer skirt belt and are respectively located on the outer sides of the folded annular edges, and the two small pressing wheels are respectively abutted to two folded annular edges of the lower-layer skirt belt.

Lower corner pinch rollers and a plurality of lower bend rollers are arranged at the joint of the middle inclined section and the horizontal feeding section, wherein the plurality of lower bend rollers are fixed between the upper layer skirt belt and the lower layer skirt belt, and each lower bend roller is pressed on the upper surface of the lower layer skirt belt respectively, so that the lower layer skirt belt is protruded downwards into a circular arc shape.

The lower corner pinch roller comprises a main shaft, two large pinch rollers and two small pinch rollers, wherein the two large pinch rollers and the two small pinch rollers are fixed on the main shaft, the main shaft of the lower corner pinch roller is fixed at the tail end of a horizontal feeding section of the rack, the two large pinch rollers are pressed on two sides of an annular base band of an upper-layer skirt belt and are respectively positioned on the outer sides of folded annular edges, and the two small pinch rollers are respectively pressed on two folded annular edges of the upper-layer skirt belt.

The upper layer shirt rim belt and the lower floor's shirt rim belt of ejection of compact section outer end all downward sloping. The ejection of compact section downward sloping, when the shirt rim belt passes through initiative cylinder, fold ring limit is downward to fully expand, be favorable to buggy or coal grain to drop more. Due to the design, most of entrained coal dust or coal particles can fall into the downstream coal sliding hopper for distribution in time.

As optimization, be equipped with a plurality of evagination on the main shaft between two little pinch rollers of upper corner pinch roller and choose the coal frame, every chooses the coal frame to constitute by two fan-shaped framves and two connecting rods between two fan-shaped framves, above-mentioned coal frame of choosing surrounds the main shaft evenly sets up, when lower floor's shirt rim belt passes through, above-mentioned choose the coal frame and push up one by one in the defeated material check that each pair of adjacent vertical baffle on the lower floor's shirt rim belt and annular baseband formed. So design, even buggy or coal grain water content are big, form the coal slime piece, the adhesion is in fold ring limit, perpendicular baffle and the contained angle between the annular base band three, when going up the corner pinch roller, is chosen the coal frame and is chosen, is convenient for the coal slime piece to drop. The pulverized coal or coal particles only fall below the discharging section of the rack in a concentrated manner, so that the pulverized coal or coal particles are convenient to collect and treat.

The large-inclination-angle belt conveyor has the advantages of simple structure, less waste of coal resources and small field pollution, and is widely suitable for coal enterprises such as large coal mines, coal preparation plants and the like.
