Detailed description of the invention
As it is shown in figure 1, the one of the present invention isolated powder flow metering device, including two-position five-way
Magnetic valve 11, powder conveyer 4 and the powder storage tank 1 that lower end is cone；Powder conveyer 4 includes horizontal long rectangular housing, and housing is provided with left right-alternative upper feeding mouth 6 and lower discharge port 5, and upper feeding mouth 6 is directly docked by flange with drain hole bottom powder storage tank 1.
Being provided with the long rectangular shaped slider 8 that can horizontally slip in housing, slide block 8 is provided with the metering cavities 7 the most vertically run through, metering cavities 7 is orthobaric volume, and the powder amount that metering cavities 7 is received every time is i.e. for unit powder flow.Slide block 8 outer surface is tightly engaged into shell inner surface, has not only ensured that slide block 8 can slide in housing but also ensure that the gap between slide block 8 and housing is the least, has prevented the powder when slide block 8 slides from falling in housing from gap.
Powder conveyer 4 side is horizontally arranged with cylinder 10, is provided with in end extends into housing and the piston rod 9 coaxially connected with slide block 8 in cylinder 10, and piston rod 9 comes and goes action band movable slider 8 synchronization action.When piston rod 9 band movable slider 8 slides into stroke one end, the upper port of metering cavities 7 is docked with upper feeding mouth 6；When piston rod 9 band movable slider 8 slides into the stroke other end, the lower port of metering cavities 7 is docked with lower discharge port 5.
The air supply opening A external compressed air pipe of two-position-five-way solenoid valve 11, working hole B connects the blow vent I of cylinder 10 by air pipe, and working hole C connects the blow vent II of cylinder 10 by air pipe, and two-position-five-way solenoid valve 11 is electrically connected to measurement controller 12.Program setting by measurement controller 12, controlling cylinder 10 by two-position-five-way solenoid valve 11 drives the slide block 8 within powder conveyor to realize coming and going action, because the powder of conveying is certain value every time, therefore powder flow value just can be calculated by the number of times of statistics two-position-five-way solenoid valve 11 break-make.Equipped with flow rate calculation, flow indication software on measurement controller 12, the touch-screen that measurement controller 12 connects is used for the amendment of operating frequency and shows instantaneous delivery and the integrated flux of powder carry.
Being provided above blanking gas blow pipe 2 bottom powder storage tank 1 in drain hole, blanking gas blow pipe 2 is annular, and is evenly arranged with gas hole on blanking gas blow pipe 2.Blanking gas blow pipe 2 connects the exhaust outlet D of two-position-five-way solenoid valve 11 by air pipe.Being provided with discharging inflatable mouth 3 on housing above lower discharge port 5, discharging inflatable mouth 3 connects the exhaust outlet E of two-position-five-way solenoid valve 11 by air pipe.
As shown in Figure 1, when two-position-five-way solenoid valve 11 when power is off, when air supply opening A and working hole C connects, working hole B communicates with exhaust outlet D, and compressed air enters cylinder 10 through air supply opening A and working hole C from blow vent II, and piston rod 9 is moved to the left, and then band movable slider 8 is moved to the left, when piston rod 9 band movable slider 8 slides into stroke left end, the upper port of metering cavities 7 is docked with upper feeding mouth 6, and the powder in powder storing tank can automatically fall in metering cavities 7.And now, the lower port of metering cavities 7 staggers lower discharge port 5, the powder entering metering cavities 7 will not be discharged.While piston rod 9 moves to left, the gas on the left of piston is entered blanking gas blow pipe 2 through working hole B and exhaust outlet D, blows the powder of powder storage tank 1 inner bottom part, it is ensured that in metering cavities 7, be full of powder.
As shown in Figure 2, when two-position-five-way solenoid valve 11 is in energising, when air supply opening A and working hole B connects, working hole C communicates with exhaust outlet E, and compressed air enters cylinder 10 through air supply opening A and working hole B from blow vent I, and piston rod 9 moves right, and then band movable slider 8 moves right, when piston rod 9 band movable slider 8 slides into stroke right-hand member, the lower port of metering cavities 7 is docked with lower discharge port 5, and the powder in metering cavities can be automatically drained out by gravity.And now, the upper port of metering cavities 7 staggers upper feeding mouth 6, do not have powder and enter metering cavities 7.While piston rod 9 moves to right, the gas on the right side of piston is entered discharging inflatable mouth 3 through working hole C and exhaust outlet E, blows the powder in metering cavities 7, it is ensured that the whole emptying of powder in metering cavities 7.
Measurement controller 12 is according to programme-control two-position-five-way solenoid valve 11 timing break-make, and driving cylinder 10 drives the slide block 8 in powder conveyor to slidably reciprocate.Owing to the powder volume of metering cavities 7 is a definite value, the number of times coming and going action in the powder conveyor unit interval is multiplied by this definite value, is i.e. the flux cumulating value of powder carry.Cylinder 10 can be set by the program in adjustment measurement controller 12 and come and go the frequency of action, and instantaneous delivery value and the cumulative flow value of conveying powder can be demonstrated on the touchscreen.
The above is only the preferred embodiment of this patent; it should be pointed out that, for those skilled in the art, on the premise of without departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection domain that also should be regarded as this patent.
