Description
Technical field
The utility model relates to a kind of backwards rotation coal flow shaping device, for carrying out coal flow shaping to the coal before entering crusher and before contracting device, is specially adapted to that coal amount is large, coal granularity is large, the coal flow shaping that particle size distribution is uneven.
Background technology
Coal Mechanical sample devices generally uses in power industry, and sampler sampling quantity is often comparatively large, and elementary increment falls into one-level feeding belt instantaneously by coal spout, in stack on one-level feeding belt.Coal stream when coal enters crusher is extremely uneven, and cause crusher to account for coal, blocking, crusher load is uneven, grinder hammerhead wearing and tearing are very fast, shorten the service life of crusher, add the number of times that crusher cleaning is safeguarded, reduce the work efficiency of sample devices.It is uneven that coal stream also causes coal to flow through the flow velocity of contracting device without effective shaping, and the requirement of contracting device cutting coal stream number of times out of reach national standard, causes the preci-sion and accuracy of contracting device poor.
Usually adopt at present and select dissimilar crusher and contracting device according to actual conditions, to play the object to coal flow shaping, as in " propagation and employment of kibbler roll in the transport of coal master's coal stream " of academic journal " Silicon Valley " 2 phases in 2013, to disclose kibbler roll place in operation in coal production, solve the series of problems because bulk spoil causes; And for example publication date is on October 15th, 2014, and publication number is in the Chinese patent of CN104096616A, discloses a kind of hammer mill with screening structure, and object is the specification meeted the requirements be crushed in transportation by the coarse coal that elevating conveyor transports.Existing method limits dissimilar crusher and the applicable surface of contracting device.
Also do not have now a kind ofly effectively to control coal stream length and the shape that coal enters crusher and contracting device, make coal stream uniform and stable, improve equipment use efficiency, extension device maintenance intervals, the preci-sion and accuracy of raising equipment, entirety improves the backwards rotation coal flow shaping device of Sampling Machine in-use performance.
Utility model content
The purpose of this utility model is to overcome the uneven problem causing crusher blocking and division preci-sion and accuracy difference of Coal Mechanical sample devices coal stream, and a kind of reasonable in design is provided, design is unique, effectively can control coal stream length and shape that coal enters crusher and contracting device, make coal stream uniform and stable, improve equipment use efficiency, extension device maintenance intervals, the preci-sion and accuracy of raising equipment, entirety improves the backwards rotation coal flow shaping device of Sampling Machine in-use performance.
The technical scheme in the invention for solving the above technical problem is: the constructional feature of this backwards rotation coal flow shaping device is: comprise coal spout, dresser, feeding belt, feeding belt support, motor, dresser support, drive belt a, feeding belt rotating shaft and drive belt b, described feeding belt axis of rotation is connected on feeding belt support, described feeding belt is movably connected in feeding belt rotating shaft, the bottom of described coal spout is positioned on the initiating terminal of feeding belt, seal between the bottom of this coal spout and feeding belt, described dresser comprises dresser rotating shaft, belt flywheel and eight groups of dresser plectrums, described belt flywheel is fixed in dresser rotating shaft, described eight groups of dresser plectrums are all fixed in dresser rotating shaft, these eight groups of dresser plectrums are uniformly distributed along the radial direction of dresser rotating shaft, often organize in dresser plectrum and be provided with opening, the degree of depth of described opening increases in the middle part of two side direction, described dresser support is fixed on feeding belt support, described dresser axis of rotation is connected on dresser support, described dresser is positioned at directly over the conveyor surface of feeding belt, described drive belt a is movably connected on belt flywheel and motor, described drive belt b is movably connected on feeding belt rotating shaft and motor, when dresser rotates, the throughput direction stirring direction and feeding belt of dresser is contrary, when the dresser plectrum base in described dresser plectrum rotates to nadir, and this dresser plectrum base and feeding belt close contact.
As preferably, the dresser plectrum side in dresser plectrum described in the utility model and the spacing between the inwall in coal spout are less than 1mm.
