Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
As shown in fig. 1, the utility model provides a positive displacement measurement feeding device, including storage silo 1, volume counter 2 and discharge hopper 3, connect through first governing valve 4 between the export of storage silo 1 and the import of volume counter 2, connect through second governing valve 5 between the export of volume counter 2 and the import of discharge hopper 3, discharge hopper 3 is used for downstream equipment output material.
The utility model discloses an among the positive displacement measurement feeding device, owing to set up volume counter 2 between storage silo 1 and discharge hopper 3, connect through first governing valve 4 between the export of storage silo 1 and the import of volume counter 2, connect through second governing valve 5 between the export of volume counter 2 and the import of discharge hopper 3, thus, can be through closing second governing valve 5, first governing valve 4 is opened, thereby make the material be full of volume counter 2, then close first governing valve 4 again, the material that has had the ration volume among the volume counter 2, open second governing valve 5 again, thus, the material in the volume counter 2 flows into discharge hopper 3 and carries downstream equipment. Therefore, the utility model discloses a positive displacement measurement feeding device can accurately measure the distribution material, simple structure, convenient to use.
In order to make the volume meter 2 measure the material accurately, the shape of the inner cavity of the volume meter 2 should be as regular as possible, the inner cavity of the volume meter 2 may be configured as a cylinder, as a preferred embodiment, the first regulating valve 4 and the second regulating valve 5 are quick-opening valves or quick-opening gate valves, the first regulating valve 4 and the second regulating valve 5 are respectively configured at the inlet and the outlet of the volume meter 2, after the material enters the volume meter 2 from the storage bin 1 to fill the volume meter 2, the first regulating valve 4 and the second regulating valve 5 block the inlet and the outlet of the volume meter 2, and then the second regulating valve 5 is opened to convey the material in the volume meter 2 to the discharge funnel 3. For convenient control of the first regulating valve 4 and the second regulating valve 5, it is preferable that the first regulating valve 4 and the second regulating valve 5 are controlled by a remote control device, and the on/off of the first regulating valve 4 and the second regulating valve 5 can be conveniently controlled by the remote control device.
In normal use the utility model discloses a during positive displacement measurement feeding device, open first governing valve 4 earlier and close second governing valve 5, make the material get into volume counter 2, the material is full of in the volume counter 2 after the definite time, and like this, volume counter 2 accomplishes once and measures the feeding circulation. Close first governing valve 4 and open second governing valve 5, open volume counter 2, the material slowly discharges the material through the discharge gate of discharge hopper 3 this moment, after the certain time, when the whole outflow of material in volume counter 2, just so accomplished once and measure the circulation of unloading. According to the circulation of the metering feeding and discharging, the metering feeding and discharging are carried out for a plurality of times, and the volume of the total discharged materials can be calculated; through the time of one-time circulation, the time for discharging a certain material can be calculated. The discharge funnel 3 has certain volume, and the time of unloading of the material of storing satisfies the time that once measures the feeding cycle of carrying on of volume counter 2, can not cause the interrupt that the material was unloaded like this, and 3 discharge gates sizes of discharge funnel need pass through the material volume that the technological requirement passed through in the unit interval of calculation, according to the material volume, combines known data density, can calculate the weight of material.
