Abstract
The utility model discloses a rotary-cut type dredging feeder and solves the problem of poor material dredging effect of the conventional equipment. The rotary-cut type dredging feeder is characterized in that a row coal hopper is partitioned at a position 1 to 1.5 m above a gate door on the lower side of the row coal hopper; the upper part of the row coal hopper is welded with an annular upper tray; the lower part of the row coal hopper is welded with an annular lower tray; a hollow driven wheel is arranged between the upper tray and the lower tray and rotates in rings of the upper tray and the lower tray; a tool rest which consists of three scraping rods is arranged in the upper part of the row coal hopper; the upper ends of the scraping rods are connected together, and the lower ends of the scraping rods are welded on the inner wall of the driven wheel; a plurality of dredging scrapers are arranged on the scraping rods; the driven wheel is connected with a driving wheel; and the driving wheel is driven by a driving device. Materials are dredged by combined rotary-cut motion of the tool rest and the scrapers; the phenomena of arching, adhesion to a wall and coal agglomeration are prevented; the materials are in a flowing state; the problem of plugging of a row coal bin is effectively solved; and the rotary-cut type dredging feeder is low in energy consumption, simple in structure, convenient to install, wide in dredging range, convenient to maintain, and high in practicability.
Description
Technical field
The utility model relates to a kind of dredging device, relates to or rather a kind of bulk material and makes the unobstructed device of mass transport.
Background technology
Former coal bunker is the important member of coal-fired plant boiler coal handling system, generally adopts the structures such as steel structure or steel reinforced concrete, and its shape top is square or is cylindrical, and the bottom is circular cone or square taper, big upper and lower small mouth, and former coal particle flows by deadweight from top to bottom.Because shrink gradually in the cross section, former coal particle more flows downward, and squeese pressure is larger, very easily causes coal dust to glue wall, knot arch, stop up when raw coal humidity or blending coal slime, causes disconnected coal, thereby has a strong impact on the smooth operation of boiler, and is especially even more serious at plum rain season.At present, be to solve run coal bin chute blockage problem, the general employing of power industry is both at home and abroad manually knocked dredging, is installed air bubble additional, dither, can alleviate to a certain extent the chute blockage phenomenon, still dredges effect undesirable; Rotation coal scuttle dredging device is installed in addition, and this device is loose highly limited, and energy consumption is high, and relatively poor to carrying the humidity such as coal slime, high moisture content, full-bodied coal effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art provides a kind of rotary-cutting type simple in structure, that energy consumption is low, dredging is effective loose feeder.
The utility model comprises former coal bunker, lock gate hatch, it is characterized in that: 1-1.5 rice cuts off former coal bunker above the bottom of former coal bunker, lock gate hatch, the top tray of upper part raw coal bucket welding annular arrangement, and the inner ring of top tray is concordant with former coal bunker inwall; The lower tray of lower part raw coal bucket welding annular arrangement, the inner ring of lower tray is concordant with former coal bunker inwall; The flower wheel of hollow is set between upper and lower pallet, between flower wheel and top tray, the lower tray sealing arrangement is set, be connected with bearing with lower tray, flower wheel rotates in the ring of upper and lower pallet; The knife rest that is comprised of three floating rules is set in upper part raw coal bucket, and on the inwall that the upper end of floating rule connects together, the lower end is welded on flower wheel, floating rule is provided with some loose scrapers; Described flower wheel connects driving wheel, and driving wheel drives with actuating device.
2-3 lower adherent scraper of pressing close to former coal bunker inwall of welding on the described flower wheel inwall.
Also weld 2-3 the upper adherent scraper of pressing close to former coal bunker inwall on the described flower wheel inwall.
The thickness 100-120mm of described upper and lower pallet; Described tool holder height 4-5m.
Described actuating device is the frequency conversion speed-down machine.
Principle of work: reductor drives flower wheel according to setting rotational speed by driving wheel, and knife rest is along with flower wheel carries out rotary-cut campaign, the material in the loose former coal bunker of loose scraper, and material keeps flowing in the coal bunker thereby make, and prevents knot arch, bridging; Simultaneously, upper adherent scraper, lower adherent scraper carry out wiper to headwall under the rotarily driving of flower wheel, prevent sticking wall; Combination rotary-cut campaign by knife rest and loose scraper, upper adherent scraper, lower adherent scraper thoroughly prevents and eliminates former coal bunker latch up phenomenon.
As shown from the above technical solution, the utlity model has following beneficial effect: 1, by the combination rotary-cut campaign bulk material of knife rest and scraper, prevent knot arch, sticking wall, canopy coal, make material keep flow regime, thereby effectively solve the run coal bin blockage problem.2, when raw coal was dry, the utility model can not start, and does not hinder material dirty yet.3, energy consumption is low, simple in structure, easy for installation, the dredging scope is wide, easy to maintenance, and practical, is mainly used in the anti-blocking block clearing of the former coal bunker of power plant boiler, the anti-blocking of other industry feed bin such as also can use.
