Abstract
The utility model discloses a double-reverse coal mixer for boilers. A pair of equilong screw conveying rods is mounted at the bottom in a coal mixing box, pitches of right screw blades which are arranged on the peripheral wall of a half of a right screw conveying rod and left screw blades which are arranged on the peripheral wall of the other half of the right screw conveying rod are equal but screwing directions thereof are opposite, pitches and lengths of right screw blades which are arranged on the peripheral wall of a half of a left screw conveying rod and left screw blades which are arranged on the peripheral wall of the right screw conveying rod are equal but screwing directions thereof are opposite, screw pitches and lengths of left screw blades which are arranged on the peripheral wall of the other half of the left screw conveying rod and the right screw blades arranged on the peripheral wall of the right screw conveying rod are equal but switching directions thereof are opposite, and the right screw conveying rod and the left screw conveying rod are driven to rotate in the same direction by a prime motor. Pressing force caused by rotation of the screw blades can be cancelled out, thereby avoiding potential failure due to pressing force, mixing coal more uniformly and increasing coal mixing efficiency.
Description
Technical field
The utility model relates to boiler with the coal-fired device that mixes, and belongs to the improvement of mixed coal device structure, particularly two oppositely boiler mixed coal devices.
Background technology
In the existing boiler mixed coal device screw rod axle only is installed, the helical blade rotation direction that is provided with on second half bar wall of helical blade and its that is provided with on half bar wall of screw rod axle is opposite, when work, when the motor prime movers drives this screw spindle rotation, can order about helical blade move block fire coal or powdery fire coal to its inner both sides from the centre of mixed coal case inside or in the mixed coal case both sides move to the centre, the both sides box wall of mixed coal case can be subjected to roof pressure (effect) power that helical blade brings because of turn (or seat power) and outwards heaves distortion like this, make securing members such as bolt that being used on the mixed coal case two side install device such as motor slowly loosening so that come off because of this roof pressure power, even influence motor etc. and be packed in steadiness on the mixed coal case tank wall, when serious, then can stop production, produce mechanical breakdown, influence carrying out in order of production work, in addition, can not mix block fire coal or powdery fire coal more even better.
The utility model content
The purpose of this utility model is to provide a kind of two oppositely boiler mixed coal device, it is rational in infrastructure, can offset the helical blade turn and the roof pressure power brought, thus the potential faults of avoiding roof pressure power to bring, also make block fire coal or powdery fire coal more even, mixed coal efficient is higher.
The purpose of this utility model is achieved in that a kind of two oppositely boiler mixed coal device, comprise prime mover, decelerator and be installed in the coal hopper upper end mixed coal case on uncovered, comprise the spiral conveyor rod that screw spindle and helical blade constitute, the helical blade that is provided with helix along its body of rod outer surface is being set on the screw spindle, mixed coal case inner bottom part is installed with a pair of isometric spiral conveyor rod, the backpitch blade uniform pitch and the rotation direction that are provided with on the periphery wall of the right-handed screw blade that is provided with on the periphery wall of half 1/2nd stock body of right-handed screw conveying lever wherein and its second half 1/2nd stock bodies are opposite, the backpitch blade uniform pitch that is provided with on right-handed screw blade that is provided with on the periphery wall of half 1/2nd stock body of backpitch conveying lever and the spiral conveyor rod periphery wall, isometric but rotation direction is opposite, the right-handed screw blade uniform pitch that is provided with on backpitch blade that is provided with on the periphery wall of second half 1/2nd stocks body of backpitch conveying lever and the spiral conveyor rod periphery wall, isometric but rotation direction is opposite, right-handed screw conveying lever and backpitch conveying lever are rotated by prime mover driven in the same way by decelerator.
The utility model is being provided with two screw rod axles, wherein, the backpitch blade uniform pitch that is provided with on second half body of rod of right-handed screw blade and its that is provided with on half stock body of right-handed screw bar axle but rotation direction is opposite, and the backpitch blade rotation direction that is provided with on the right-handed screw blade that is provided with on half stock body of backpitch bar axle and the right-handed screw bar axle is opposite to constitute the mirror image symmetry, in like manner, the right-handed screw blade rotation direction that is provided with on the backpitch blade that is provided with on second half stock body of backpitch bar axle and the right-handed screw bar axle is opposite to constitute the mirror image symmetry, helical blade on every screw rod axle is symmetrical and rotation direction is opposite, the helical blade rotation direction that is provided with respectively on two screw rod axles is opposite respectively and symmetrically, therefore, when prime mover rotates in the same way at two bar axles of drive, the roof pressure power that mixed coal case tank wall is applied of the helical blade on screw rod axle is opposite with the roof pressure force direction of the mutual roof pressure that the helical blade on another root screw rod axle produces in the middle of the coal storage case, thereby the roof pressure power that two screw rod axles helical blade is separately produced is respectively cancelled out each other, and because helical blade on a screw rod axle will be in block fire coal or powdery fire coal middle part in the coal storage case of both sides in the coal storage case moves when mixing, helical blade on another root swing arm axle will be in the block fire coal or the powdery fire coal at middle part in the coal storage case and move mixing in both sides in the coal storage case, can reach in shorter time the purpose of mixed coal better with this.Therefore, the utility model is rational in infrastructure, can offset the helical blade turn and the roof pressure power brought, thereby the potential faults of avoiding roof pressure power to bring makes also block fire coal or powdery fire coal more even, and mixed coal efficient is higher.
