Abstract
The utility model discloses a comb type hunk removing device for a coal conveying system with automatic dredging function, which belongs to the field of machinery, and is used for removing hunks in power plant coal conveying system and overcoming the defect of local blockage of the current comb type hunk removing device. A plurality of sickle-shaped crank shifting teeth are serially connected on a shifting tooth shaft to form comb type local sifter surfaces, the local sifter surfaces are formed to a framework of an integral sifter surface, the box bodies of the sifter surfaces are enclosed, and the local sifter surfaces rotate to drive a motor, a rotating handle and a connecting rod; and the comb type hunk removing device is characterized in that shaft sleeves rotating with the shifting tooth shafts are installed on the shifting tooth shafts between the shifting teeth, and a plurality of cutting teeth are fixed on the shaft sleeves. The comb type hunk removing device disclosed by the utility model has the positive effects that the cutting teeth on the shaft sleeves extrude and cut the hunks stained at the position during the rotation process with the shifting tooth shafts so as to gradually shrink the volumes of the hunks, and the hunks drop on the conveying system through the sifter surfaces if the volumes of the hunks are smaller than the distance between the shifting tooth shafts to remove the local blockage of the sifter surfaces and keep the optimal working state of the hunk removing device.
Description
Technical field
The invention belongs to mechanical field, be specifically related to large-scale with scalper subset in the coal yard institute coal.
Background technology
Coal, generally all has and considers in advance removing of coarse coal for preventing the damage of coarse coal to transmission equipment in big consumption places such as thermal power plants.Before this, some thermal power plants use turns the shape tooth by several sickle shapeds that are separated of string dress on an axle and constitutes the local compass screen surface of comb formula, is connected mutually by several local compass screen surfaces head and the tail and forms complete compass screen surface; The comb formula that adjacent local compass screen surface oppositely rotates in being bordering on 90 ° of scopes of level and numerical value direction is removed big block assembly; Can bulk be removed with separate mode reasonably, but find in actual the use, volume is less than coaxial when going up adjacent fingers and being a bit larger tham local screen cloth rotating shaft in running into bulk; Promptly can not be dialled away by broach; Can not see through compass screen surface again and fall, wriggle, cause follow-up fines to stop at the bulk periphery but be trapped in the sieve aperture; Make compass screen surface cause local the obstruction, influence the work efficiency of equipment.
Summary of the invention
The purpose of this invention is to provide a kind of coal handling system that has from the block clearing function and remove big block assembly, be used for power plant's coal handling system and remove bulk, overcome existing comb formula and remove the deficiency that the part of big block assembly existence is stopped up with the comb formula.
Of the present invention have remove big block assembly from the coal handling system of block clearing function with the comb formula and comprise: several sickle shapeds are turned the shape moving tooth string that is separated and are contained in the local compass screen surface of the pectination that constitutes on the moving tooth axle; The framework of several local compass screen surfaces being formed whole compass screen surface; Crowd around the casing of compass screen surface, by the electrical motor that drives the compass screen surface swing, on the motor reel turning handle, connect the electrical motor turning handle connecting rod, connect the compass screen surface driver train that the turning handle of connecting rod and moving tooth axle is formed.Electrical motor wherein, connecting rod and turning handle are positioned at each local compass screen surface near reciprocally swinging in vertical and the horizontal extent; And when forming the odd positions compass screen surface and moving to the vertical position stop, the local compass screen surface of even number position is from level or near the starting point of the level attitude movement relation of swing upwards.The improvement of being done is the axle sleeve that rotates with the moving tooth axle to be installed between each moving tooth on each moving tooth axle, to be fixed with several cuttings on the axle sleeve.
Good effect of the present invention is: the cutting on the axle sleeve forms in the rotation of moving tooth axle the bulk that is trapped in this place is pushed, cut; The bulk volume is dwindled gradually; When seeing through compass screen surface to less than the moving tooth distance between shafts time, falls on the delivery system size reduction; Remove the part of compass screen surface and stop up, keep removing the optimum Working of big block assembly.

The specific embodiment
Consult Fig. 1, Fig. 2; Comprising that several sickle shapeds being turned shape moving tooth 1 string that is separated is contained in the local compass screen surface of the pectination that constitutes on the moving tooth axle 2; The framework 3 of several local compass screen surfaces being formed whole compass screen surface; Crowd around the casing 4 of compass screen surface; By first turning handle 6 on the electrical motor 5 that drives the compass screen surface swing, the motor reel, connect the connecting rod 7 of electrical motor turning handle, second turning handle 8 that connects connecting rod and tooth axle and electrical motor 5, first turning handle 6, connecting rod 7 and second turning handle 8 each local compass screen surface be positioned near reciprocally swinging vertically and in the horizontal extent; And when forming the odd positions compass screen surface and moving to the vertical position stop, the local compass screen surface of even number position from level or near the starting point of level attitude upwards the comb formula of the movement relation of swing remove on the big block assembly.Axle sleeve 9 is being installed between each moving tooth on the moving tooth axle, fixing several alloy cuttings 10 on the axle sleeve, there is keyway corresponding axle sleeve position on axle sleeve 9 and the moving tooth axle 4, is embedded with the connecting key that stops axle sleeve to rotate relative to the tooth axle in the keyway.
