The material distribution device comprises a housing, a speed reduction motor, a roller and spoke plates, wherein the roller is arranged in the housing and driven by the speed reduction motor, and the spoke plates are detachably and uniformly arranged along the periphery of the roller. The material distribution device disclosed by the invention adopts the detachable spoke plate type roller and multi-working position regulation and variable-frequency speed reduction type drive so as to overcome the defects of low circulation capacity, easiness in causing coal blockage, poor regulation capacity of coal flow and the like of an old cushioning device. The material distribution device further has the advantages of simple structure, convenience in use, easiness in operation, convenience in maintenance and overhaul and the like, and can better control the motion state of materials under various conditions and realize optimal operation working conditions of the fine crusher. The device can be applied to not only coal crushing systems of large and medium-sized thermal power plants, but also bulk material crushing systems in coal, metallurgy, mining, building materials and other industries, and further has a wide range of applications and good development prospects.
Description
Technical field
The present invention relates to a kind of distribution device, particularly relate to a kind of fine crusher distribution device that is applied in the broken coal system of thermal power plant.
Background technology
Owing to the fast development of China's power industry, recirculating fluidized bed power plant is more and more at present, and its scale is also increasing.The large circulating fluidized bed boiler burnt fuel mainly is to be main with colm; Because pulverized coal preparation system is not set; And the steam generator system of power plant necessarily requires the granularity of raw coal will be below 6～8 millimeters, so such power plant is provided with the fine granularity coal breaker in fortune coal measures system.
The fine granularity coal breaker is had relatively high expectations to the pan feeding condition, requires material will be distributed in rotor tup surface in the horizontal direction, and the drop of pan feeding height will be strict controlled in about 1～1.5 meter.For this reason, all require to be provided with distributing device at the fine crusher feeding mouth with buffering and refining function.Old-fashioned distributing device generally adopts baffle plate to add the pattern of cylinder.Because baffle plate and cylinder are big through the ability influence to coal stream; Regulating power to coal stream is relatively poor, and in actual motion, the cloth effect is bad; Chang Yi causes phenomenons such as chute blockage, the wearing and tearing of fine crusher tup are unbalanced, the discharging-material size grating is bad, and is bigger to the influence of boiler of power plant operational efficiency.Given this; A kind of new-type fine crusher distribution device of necessary design can be in operation it and reduces the drop of coal stream, the initial velocity of buffering and the materials flow of scalable fine crusher inlet; Make its evenly material feeding on the length direction of whole hammer axle; Both optimized the discharging-material size grating of fine crusher, and also avoided the part tup to cause heavy wear, thereby improved the fine crusher runnability, increase the service life because of the concentration of local material feeding.
Summary of the invention
The object of the invention just provides a kind of novel fine crusher distribution device; Can be in operation and reduce the drop of coal stream; The initial velocity of buffering and the materials flow of scalable fine crusher inlet; Make its evenly material feeding on the length direction of whole hammer axle, both optimized the discharging-material size grating of fine crusher, also avoid the part tup to cause heavy wear because of the concentration of local material feeding.
The object of the invention is realized through following technical proposals:
A kind of novel fine crusher distribution device comprises shell, reducing motor, cylinder, disc, and cylinder is arranged in the shell and is driven by reducing motor, along the detachable disc that evenly is provided with of roll circumference.
Further, there is charging aperture on said shell top, and there is discharging opening the bottom, and its opening size increases gradually from charging aperture to shell middle part, reduces gradually from shell middle part to its opening size of discharging opening.
This structure more helps reducing the drop of coal stream, and the initial velocity of buffering and the materials flow of adjusting fine crusher inlet makes its evenly material feeding on the length direction of whole hammer axle.Coal stream is after charging aperture gets into the shell; The disc that is rotated is broken up, and increases gradually from charging aperture to shell intermediate openings size, forms the horn-like structure of back-off; This structure can prevent that being broken up the coal that upwards flies by disc flows the charging aperture that flies out; And launched downwards by outer casing inner wall, broken up by the disc secondary, further its granularity of refinement.Reduce gradually from the opening size of shell middle part to discharging opening; Form the horn-like structure of upward opening; This structure makes is broken up the coal stream and outer casing inner wall collision that flies downwards by disc, and speed reduces the effect of playing buffering, and slips into discharging opening from the outer casing inner wall that tilts; Get in the fine crusher, make whole hammer axle in the even material feeding of length direction.
Further, said reducing motor is a variable frequency reducer motor.
The employing variable frequency reducer motor can be according to the different operating modes of reality; Water content like kind variation, the large and small inequality of granularity of material, material is not equal; Output speed to motor carries out speed governing through frequency converter; Thereby control gets into the material movement state of fine crusher, reaches the best operational effect of fine crusher.
Further, the cylinder position in the said shell can be in its rotation direction adjustment.
This structural design; Can adjust the station of cylinder, adapting to different working conditions, not equal like the water content of the kind variation of material, the large and small inequality of granularity, material; Thereby control gets into the material movement state of fine crusher, reaches the best operational effect of fine crusher.
Further, said side wall of outer shell is offered the cylinder fixing hole more than two pairs, and cylinder detachably is fixed in the shell through fixing hole.
Further, said side wall of outer shell is offered chute, and the cylinder two ends are fixed in the chute, and can move along chute.
Action principle of the present invention is following:
Coal stream gets into the shell from charging aperture; The reducing motor head roll rotates, and rotates coal stream is broken up thereby drive disc on the cylinder, and the coal stream of being broken up scatters and flies out and outer casing inner wall collides; Reach deceleration buffer; Reduce the purpose of drop, get into the fine crusher, make whole hammer axle in the even material feeding of length direction from discharging opening.Simultaneously, can regulate the rotating speed of cylinder and the position of fore-and-aft direction in the enclosure thereof, get into the material movement state of fine crusher, reach the best operational effect of fine crusher with control according to different working conditions.
Beneficial effect of the present invention is:
Adopt removable disc formula cylinder, multistation position adjustments and frequency control formula to drive, overcome defectives such as low through ability, the easy chute blockage of old-fashioned buffer unit stream, coal stream regulating power difference.And have simple in structure, easy to use, easy operating, be convenient to advantages such as maintenance, maintenance, can control the material movement state under various conditions preferably, realize the fine crusher optimal operating condition.
This device can also be applied to be with a wide range of applications and bright development prospect in the bulk material crushing system of industries such as coal, metallurgy, mine, building materials except that being applied to large and medium-sized thermal power plant broken coal system.
