Description
Technical field
The present invention relates to raw coal conveying device under the coal mine, be specially belt conveyor capable of dewatering.
Background technology
In the downhole production process, influenced by mining conditions, the working face water yield is big, uses drainage equipment in time to discharge, and causes the raw coal of a large amount of water bursts and production to be transported on the adhesive tape conveyor by the working face drag conveyor together.And the upper supporting roller of existing adhesive tape conveyor is the flute profile carrying roller that is made of three carrying rollers, adhesive tape on it also correspondingly is a flute profile, water in the raw coal can't be discharged on adhesive tape, cause adhesive tape conveyor to skid, can't normally move, after the raw coal that water content is big is transported to shaft coal pocket, in putting the coal process, very easily scurry the coal phenomenon, the main rubber conveyer that promotes can not run well, the influence safety in production.Do not see belt conveyor capable of dewatering at present, do not see relevant bibliographical information yet.
Summary of the invention
The present invention provides a kind of belt conveyor capable of dewatering in order to solve the problem that does not have belt conveyor capable of dewatering at present.
The present invention adopts following technical scheme to realize: belt conveyor capable of dewatering, comprise frame, be supported in upper supporting roller and the snub pulley on the frame and be supported in (closed loop) adhesive tape on each carrying roller (because adhesive tape is a closed loop, so adhesive tape has formed the upper and lower); Upper supporting roller is thick (diameter is big) two end portions of the mid portion of single carrying roller and upper supporting roller thin (diameter is little), and it is low to make the upper strata adhesive tape be middle high both sides; Frame top be fixed be positioned at upper strata adhesive tape top, two ends are the fan housing that import and export and top are provided with air inlet.According to the natural quality that Water seeks its own level, under the situation that does not influence the adhesive tape conveyor transport capacity, change upper supporting roller into single carrying roller and the thin shape of the thick two end portions of mid portion, high both sides are low in the middle of making the upper strata adhesive tape, but make the water spontaneous current both sides in the raw coal on the adhesive tape, drop to by the upper strata tape edge and discharge with water pump after ditch, upper edge, floor flows to sump; Because the effect of water adhesive force so still can not thoroughly purify water.During use, secondary fan is linked to each other with air inlet on the fan housing with air duct.Wind by secondary fan's fan-out enters in the fan housing through air duct, air inlet, adhesive tape and on raw coal through fan housing, under the wind-force effect, raw coal is realized further dehydration.
The upper supporting roller of belt conveyor capable of dewatering of the present invention changes single drum type carrying roller into by the groove profile carrier roller group; And set up the wind-force dewater unit, and successfully solved in the downhole production process because the working face water yield is big, use that adhesive tape conveyor promotes, skid during transportation and shaft coal pocket is scurried the coal problem.Through actual tests, use, this adhesive tape conveyor dehydrating effect is remarkable, and dehydration rate can reach 90-95%, has improved the scope of application of adhesive tape conveyor, and the normal safety in production of the big working face of water burst is become a reality.

The specific embodiment
Belt conveyor capable of dewatering comprises frame 1, is supported in upper supporting roller 2 and the snub pulley 3 on the frame 1 and is supported in (closed loop) adhesive tape 4 on each carrying roller; Upper supporting roller 2 is thick (diameter is big) two end portions of the mid portion of single carrying roller and upper supporting roller 2 thin (diameter is little), and it is low to make upper strata adhesive tape 4 be middle high both sides; It is the fan housing 6 that import and export and top are provided with air inlet 5 that frame top is fixed with the two ends that are positioned at adhesive tape top, upper strata.During concrete enforcement, the thin upper supporting roller 2 of the thick two end portions of mid portion can be by realizing at the solid cydariform overcoat 7 of existing straight shape upper supporting roller middle part cover.Like this, both utilize the parts on the existing transporter, simplified manufacturing procedure again.
The axis of the air inlet 5 on the fan housing 6 tilts to the fan housing outlet side, makes the axis of air inlet 5 become angle α with the adhesive tape plane vertical direction.Can make wind direction opposite like this, to improve dehydrating effect with the coal flow path direction.For further optimizing structure, angle α need meet:
The angle of the axis of α-air inlet and adhesive tape plane vertical direction in the formula
V-adhesive tape speed of service m/s
A-air inlet section m

Q-fan delivery m
3/ s
The inside bending in biside plate lower end of fan housing 6 makes dogleg section become 130 degree angles with adhesive tape, is fixed with adjustable overlap joint rubber 11 in the dogleg section end.Adjustable overlap joint rubber 11 lower ends and adhesive tape leave the 5-10mm gap.Stayed passage for the wind-force draining like this, can also prevent that wind-force from blowing down adhesive tape with raw coal, structure is optimized.
Flexible air curtain 8 is set on the import and export of fan housing 6, guarantees that the raw coal of upper strata adhesive tape transportation passes through smoothly, and work the effect of keeping out the wind.
Be fixed with " wedge " shape collection coal block 9 that is positioned at above the adhesive tape of upper strata symmetrically at the frame top of fan housing 6 imports one end." wedge " shape collection coal block 9 make raw coal in the dispersion of distribution of upper strata adhesive tape less than the fan housing throat width, so that raw coal passes through fan housing smoothly; Collecting coal block 9 simultaneously also has squeezing action to raw coal, further realize moisture content of coal from.Water after the separation is forced to scrape by flexible air curtain before entering fan housing.Be fixed with the adhesive tape scraper cleaner 10 that is positioned at above lower floor's adhesive tape on the frame 1.Trickle down at a little raw coal of lower floor's adhesive tape and the water of wandering on lower floor's adhesive tape and can clear up on the floor during collection coal block collection coal by adhesive tape scraper cleaner 10.Adhesive tape scraper cleaner 10 is angled with lower floor's adhesive tape, helps the cleaning of lower floor's adhesive tape like this.
