preferably, described weighing apparatus is four LOAD CELLS, and described hopper of weighing is installed on a support by the LOAD CELLS described in these four.
preferably, described hopper of weighing is provided with the vibrating motor for auxiliary discharging.
preferably, the driving cylinder that described shedding mechanism comprises the discharge valve of the discharge outlet being arranged on described hopper of weighing, the discharge valve described in driving opens or cuts out, described driving air cylinder signal is connected to described control unit.
preferably, described transport sector is be connected to the conveyer between the discharging opening of corresponding described hopper of weighing and described mixer.
beneficial effect of the present invention is: the coal accurately being measured the flare point of required correspondence by the weighing apparatus be made up of four LOAD CELLS; the amount of the coal of weighing in hopper can be monitored in real time; not easily cause excessive problem; and be sent to mixed cell by transport sector; whole system all adopts electrically and Mechanical course; without the need to artificial participation; there will not be personal error; more accurately, efficient; more be reduction of the labour intensity of workman; can large-scale be realized, meet needed for every field, be suitable for promoting the use of in colliery or energy company etc.

Detailed description of the invention
below in conjunction with embodiment shown in the drawings, the present invention is described in detail below:
as shown in accompanying drawing 1 and accompanying drawing 2, Coal Blending System of the present invention, for the first coal and the second coal with different flare point are mixed into the Mixture Density Networks of required flare point according to the proportioning preset, comprise weighing unit, mixed cell and control unit 4, weighing unit comprises two Weighing mechanisms being respectively used to take the first coal and the second coal, two transport sectors that mixed cell comprises the mixer 11 for the first coal and the second coal being mixed and respectively the first coal and the second coal is delivered to mixer 11, Weighing mechanism comprises the bucket 1 for holding the first coal or the second coal, for measuring the hopper 2 of weighing of the first coal or the second coal, hopper 2 of weighing is positioned at the discharge outlet of bucket 1, bucket 1 is provided with for driving its driving reinforced in hopper 2 of weighing to feed in raw material motor 3, the discharging opening of hopper 2 of weighing extends to corresponding transport sector place, weighing on hopper 2 is provided with for driving it to the shedding mechanism of transport sector discharging, weigh on hopper 2 and be provided with weighing apparatus, weighing apparatus signal is connected to control unit 4, reinforced motor 3 signal is driven to be connected to control unit 4, weighing apparatus is four LOAD CELLS 5, hopper 2 of weighing is installed on a support 6 by these four LOAD CELLS 5, to weigh the vibrating motor 7 hopper 2 is provided with for auxiliary discharging, bucket 1 is arranged on the top of support 6, namely bucket 1 is setting up and down with hopper 2 of weighing, the discharge bucket of bucket 1 is positioned at weigh the top of hopper 2, four LOAD CELLS 5 circumferences are evenly distributed on weighs between hopper 2 and support 6, shedding mechanism comprises the discharge valve 8 of the discharge outlet being arranged on hopper 2 of weighing, discharge valve 8 in the driving cylinder 9(the present embodiment driving discharge valve 8 to open or cut out is two and half arc bodies, the driving cylinder 9 of both sides is had to control respectively, outwards can overturn and open), cylinder 9 signal is driven to be connected to control unit 4, transport sector is be connected to the conveyer 10 between the discharging opening of corresponding hopper 2 of weighing and mixer 11, above-mentioned control unit 4 selects PLC.
the working process of native system: according to required proportioning, the weight Input Control Element 4 of the first coal and the second coal will be needed, start and drive reinforced motor 3, to weighing, 2 kinds, hopper injects corresponding coal, and in real time the data of weighing are back to control unit 4 by four LOAD CELLS 5 in whole process, when value of weighing reaches required amount, then controlled to drive reinforced motor 3 to quit work by control unit 4, next the driving cylinder 9 passing through correspondence by control unit 4 again opens the discharge valve 8 below two hoppers 2 of weighing respectively, start the first coal and the second coal to be discharged on corresponding conveyer 10, in process, can limit discharge side be assisted reinforced by vibrating motor 7, or open vibrating motor 7 in the ending of discharging, unload the clout of 2 kinds, hopper of totally weighing, to reduce error, by two conveyers 10, the first coal and the second coal are delivered in mixer 11 like this, carry out the process such as follow-up mix and blend again.
the invention provides a kind of mixing system of the coal for blending required flare point, it accurately measures the coal of the flare point of required correspondence by the weighing apparatus be made up of four LOAD CELLS, the amount of the coal of weighing in hopper can be monitored in real time, not easily cause excessive problem, and be sent to mixed cell by transport sector, whole system all adopts electrically and Mechanical course, without the need to artificial participation, there will not be personal error, more accurate, efficiently, more be reduction of the labour intensity of workman, large-scale can be realized, meet needed for every field, be suitable for promoting the use of in colliery or energy company etc.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to the present invention's spirit change or modify, and all should be encompassed within protection scope of the present invention.
