Description

A kind of thermal power plant double-roll type coal crushing device
Technical field
The utility model is related to thermal power plant's apparatus equipment technical field, and in particular to a kind of thermal power plant is broken with double-roll type coal Crushing device.
Background technology
Thermal power plant be by the use of coal, oil, natural gas as fuel production electric energy factory, its basic process of production is: Combustion heating water makes into steam to fuel in the boiler, and the chemical energy of fuel is transformed into heat energy, and steam pressure pushing turbine revolves Turn, heat energy is converted into mechanical energy, then steam turbine drives generator rotation, and mechanical energy is transformed into electric energy.
Thermal power generation main fuel is exactly coal at present, in order to improve the efficiency of coal burning, needs to break block coal Coal dust is worn into after broken, is often mixed into some ferrous metal impurity in real process, if entering boiler can be sintered in boiler Interior, impact boiler is used.In addition, traditional coal crusher coal particles out are relatively rough uneven, burning can be also affected Efficiency.
Utility model content
(One)Technical problem to be solved
For solving the above problems, the utility model proposes a kind of simple structure, improves operating efficiency, can effectively remove coal Ferrous metal impurity in charcoal, improves thermal power plant's double-roll type coal crushing device of coal crushing efficiency.
(Two)Technical scheme
A kind of thermal power plant of the present utility model double-roll type coal crushing device, including housing, movable pulley, feed hopper, magnetic Property conveyer belt, belt-driven motor, scraper plate, irony receiver, the first motor, the second motor, cracking cabin, bidentate Roller, double smooth rolls, discharging opening;The coal cinder and metal impurities are dropped on magnetic feed belt after entering feed hopper, and conveyer belt drives Dynamic Motor drive conveyer belt operating, coal cinder is dropped in cracking cabin, and metal impurities are turned at scraper plate, are scraped irony In receiver;First motor is rotated clockwise by belt drives double teeth roller left side wheels and double smooth roll left side wheels edges, and second Motor is rotated counterclockwise by belt drives double teeth roller right-hand wheel and double smooth roll right-hand wheel, secondary so as to carry out coal cinder Discharging opening is dropped into after crushing.
Further, the left roller of the left roller of the double teeth roller and double smooth rolls is respectively provided with regulation spring, in order to adjust Two running roller gaps, so as to adjust crushed particles size.
Further, the discharging opening arranges resilient dust dividing plate.
Further, the cracking cabin bottom is 35 degree of inclined-planes.
(Three)Beneficial effect
Compared with prior art, which has the advantages that the utility model:A kind of thermal power plant of the present utility model With double-roll type coal crushing device, simple structure, reasonable in design, the iron being mixed in coal can effectively be removed by magnetic conveyer belt Matter metal impurities, prevent from damaging coal pulverizer or enter burning in boiler, reduce boiler combustion efficiency, carry out just through double teeth roller After level is broken, then second-time breakage is carried out through double smooth rolls, the coal particles after making to crush are uniform, facilitate post-production to use, greatly Operating efficiency is improve greatly.
Description of the drawings
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment Or accompanying drawing to be used is briefly described needed for description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work Under, other accompanying drawings can also be obtained according to these accompanying drawings.
