The utility model provides a technical scheme that its technical problem adopted is: a quantitative conveying system for pulverized coal comprises a coal bunker fixed on an upper floor, a transition tank fixed on a middle floor and a rotor scale arranged on the ground, wherein a blanking hopper is arranged at the bottom of the coal bunker, a rotary feeding valve is arranged at the top of the transition tank, the blanking hopper is in flexible connection with the top of the rotary feeding valve, the bottom of the transition tank is in flexible connection with an inlet of the rotor scale, the bottom of the rotor scale is connected with a Roots blower for supplying air to the rotor scale through a pipeline, and an outlet of the rotor scale is connected with a negative-pressure coal conveying pipe.
Further, the lower hopper is sleeved at the bottom of the coal bunker from the outside, and the top of the lower hopper and the outer wall of the coal bunker are sealed.
Furthermore, the periphery of the discharging hopper is provided with an air pipe, and the air pipe is provided with a plurality of hoses for blowing the pulverized coal away from the inner wall of the discharging hopper.
Furthermore, the top of the transition tank is communicated with a dust collection bag through a pipeline.
Furthermore, one end of the rotor scale is fixed, and the other end of the rotor scale is elastically connected with the middle-layer floor slab through a spring.
The utility model has the advantages that: a quantitative conveying system for pulverized coal comprises a coal bunker fixed on an upper floor, a transition tank fixed on a middle floor and a rotor scale arranged on the ground, wherein a blanking hopper is arranged at the bottom of the coal bunker, a rotary feeding valve is arranged at the top of the transition tank, the blanking hopper is in flexible connection with the top of the rotary feeding valve, the bottom of the transition tank is in flexible connection with an inlet of the rotor scale, the bottom of the rotor scale is connected with a Roots blower for supplying air to the rotor scale through a pipeline, and an outlet of the rotor scale is connected with a negative-pressure coal conveying pipe. The utility model discloses a gyration feed valve guarantees the equilibrium of unloading, adopts the rotor scale to guarantee the ration supply of buggy to guarantee the firepower balance in the cement kiln, thereby realize cement manufacture's automation and ration controllable.

Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1, the quantitative conveying system for pulverized coal of the present embodiment includes a coal bunker 1 fixed on an upper floor, a transition tank 2 fixed on a middle floor, and a rotor scale 3 disposed on the ground, wherein a discharge hopper 4 is disposed at the bottom of the coal bunker 1, a rotary feed valve 5 is disposed at the top of the transition tank 2, the discharge hopper 4 is in flexible connection with the top of the rotary feed valve 5, the bottom of the transition tank 2 is in flexible connection with an inlet of the rotor scale 3, the bottom of the rotor scale 3 is connected with a roots blower 6 for supplying air to the rotor scale 3 through a pipeline, and an outlet of the rotor scale 3 is connected with a negative pressure coal conveying pipe 7.
The utility model discloses a coal bunker 1 stores a large amount of pulverized coals that have ground, perhaps coal bunker 1 is as the temporary storage point of pulverized coals, and its bottom generally is provided with the ooff valve, when needs carry the pulverized coals, opens the ooff valve, and the pulverized coals falls into under the action of gravity hopper 4 down, because the bottom outlet of hopper 4 is less, and the pulverized coals is too thin, for preventing the pulverized coals from gluing on the inner wall of hopper 4 down, the periphery of hopper 4 down is provided with tuber pipe 8, tuber pipe 8 is provided with a plurality of hoses 81 that blow off the pulverized coals from the inner wall of hopper 4 down; additionally, the utility model discloses a gyration feed valve 5 can prevent to heavily press for a long time by the buggy to cause the valve body to warp on the one hand, on the other hand, gyration feed valve 5 can turn over the below to the material of top to destroy the effect of piling up of buggy, thereby make the buggy can smoothly fall when the operation.
The buggy passes transition jar 2 falls into rotor scale 3 can produce the raise dust, and for preventing the raise dust too big, the top of transition jar 2 has dust bag 9 through the pipeline intercommunication. One end of the rotor scale 3 receives materials, and the weighed materials are sucked into the negative pressure coal conveying pipe 7 by the double functions of the Roots blower 6 and the negative pressure coal conveying pipe 7 at the other end in the continuous rotation process; the rotor scale 3 can be weighed according to the parts, and the pulverized coal entering the negative pressure coal conveying pipe 7 every time also enters the negative pressure coal conveying pipe according to the parts, so that the quantitative control is realized, the stable fire of the cement kiln is finally ensured, and the quantitative control of the cement production is realized.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
