Description
Technical field
The utility model is the feeding device that industries such as a kind of electric power, oil refining, chemical industry, pharmacy are used to carry the powder granule material, particularly the automatic feeding device of a measurable and continuous conveying powder material.
Background technology
Existing granular material feeding device, its added inventory, measure by following dual mode: the one, allow streams through a S shape material blanking tube, to obtain a metastable demarcation flow velocity, calculate the inventory that falls into feedway by the time of control blanking again.This kind metering method is comparatively rough, and its important parameter-flow velocity is subjected to the pressure influence of top storage silo and below transfer pot, produces bigger fluctuation, can cause metering than large deviation; The 2nd, by Weighing module or sensor the material that falls into tank body is carried out real-time weighing, because in the process that material falls, be subject to shake the influence with external factor such as temperature, so the meterage in weighting mode is short of stable and accuracy.
Aspect the continuous conveying of material, existing feeding device adopts the single transmit tank structure more, its course of conveying is: charging-charging end-conveying-conveying end-charging again-carry again can only be intermittently discrete so carry, and can not realize round-the-clock conveying.
The utility model content
The purpose of this utility model is in order to overcome inaccurate, the discontinuous defective of mass transport of existing feeding device inventory metering, to invent a kind of automatic feeding device that can accurately measure the measurable and continuous conveying powder material of material and the continuous convey materials of energy.
The purpose of this utility model realizes as follows: the automatic feeding device of described measurable and continuous conveying powder material, comprise storage warehouse, measuring chute, sending warehouse, air-blast device, storage warehouse is communicated with measuring chute from the bottom by inlet valve, measuring chute is communicated with sending warehouse from the bottom by the intermediate feed valve, and sending warehouse is connected with discharge nozzle by bleeder valve; Storage warehouse is communicated with measuring chute from the top by blow off valve, and measuring chute is communicated with sending warehouse from the top by balance cock; Measuring chute, sending warehouse and discharge nozzle are connected with air-blast device by compensating air valve, conveying air valve and purging air valve respectively; On measuring chute, be provided with high charge level meter and low level-sensing device; On measuring chute, sending warehouse and discharge nozzle, be respectively equipped with pressure transformer.
Good effect of the present utility model is as follows: the utility model adopts the structure of two warehouses up and down, the conveying of package unit is to control by small PLC controller program according to the rules, realized quantitatively and continuously the carrying of material, thereby satisfied in the industrial process quantitative and continuous interpolation demand granular material.

The specific embodiment
As shown in Figure 1, the automatic feeding device of described measurable and continuous conveying powder material, comprise storage warehouse 16, measuring chute 1, sending warehouse 2, air-blast device 14, storage warehouse 16 is communicated with measuring chute 1 from the bottom by inlet valve 3, measuring chute 1 is communicated with sending warehouse 2 from the bottom by intermediate feed valve 5, and sending warehouse 2 is connected with discharge nozzle 15 by bleeder valve 9; Storage warehouse 16 is communicated with measuring chute 1 from the top by blow off valve 4, and measuring chute 1 is communicated with sending warehouse 2 from the top by balance cock 6; Measuring chute 1, sending warehouse 2 and discharge nozzle 15 are connected with air-blast device 14 by compensating air valve 7, conveying air valve 8 and purging air valve 10 respectively; On measuring chute 1, be provided with high charge level meter 11 and low level-sensing device 12; On measuring chute 1, sending warehouse 2 and discharge nozzle 15, be respectively equipped with pressure transformer 13.
In the use, various valves and pressure transformer are connected with the PLC control housing by circuit, the control that the PLC control housing opens or closes the various valves of this device.At first open the inlet valve 3 and the blow off valve 4 of measuring chute 1 top, the material by gravity freely falls in the measuring chute 1 from storage warehouse 16, the low level-sensing device 12 and the high charge level meter 11 that are installed on the measuring chute 1 trigger successively, after PLC control housing 15 receives the high charge level signal, close inlet valve 3 and blow off valve 4, then open intermediate feed valve 5 and balance cock 6 between measuring chute 1 and the sending warehouse 2, at this moment material falls into sending warehouse 2, after the low level-sensing device 12 of measuring chute 1 triggers once more, close intermediate feed valve 5 and balance cock 6; Next open and carry air valve 8, when sending warehouse 2 to the pipeline back pressure, open and purge air valve 10 and bleeder valve 9, at this moment begin to carry out the conveying of material, it is full and trigger high charge level meter 11 that measuring chute 1 beginning simultaneously is fed to material once more, when the conveying of sending warehouse 2 begins toward sending warehouse 2 feeds when finishing again.Before carrying beginning, PLC controller 15 will obtain and write down the pipeline back pressure, and in course of conveying, the pressure of sending warehouse 2 will rise earlier and afterwards descend, if pressure drops to the pipeline back pressure, promptly the initial back pressure of pressure differential deltap P=sending warehouse pressure-pipeline=0 is then carried and finished.By setting a Δ P
sValue is controlled conveying near completeness, and PLC compares Δ P and Δ P in real time
sIf equating then to judge material finishes near being transferred, open compensating air valve 7 this moment to measuring chute 1 inflation, when measuring chute 1 pressure rises to after the pressure of sending warehouse 2 is consistent, open intermediate feed valve 5 and balance cock 6, at this moment material will fall into by gravity and continue in the sending warehouse 2 to carry, after the low level-sensing device in the measuring chute 1 12 triggers, close compensating air valve 7, intermediate feed valve 5 and balance cock 6, sending warehouse 2 continues to keep carrying, 1 then charging of measuring chute is so under the control of PLC, this device is in continuous feed status.
