Background technology
In power production process, as the production process of metal-powder, such as nickel powder is adding sulphur modification production process, needs the sulphur powder adding trace.The interpolation of the powder of this trace, must strictly control to add powder amount and disposable addition, this is because first owing to being micro powder, if addition controls not in place, probably adds or adds less, affecting reaction mass; Another aspect existing " microscale feeder " (helix line rotating discharge) at present, often the design charging upper limit, can cause " plug machine " phenomenon, use very inconvenient, add the maintenance down that will cause whole machine a little.
Utility model content
The technical problems to be solved in the utility model is to provide one and avoids " plug machine " phenomenon, and operational throughput is more small, is low to moderate per second or per minute 0 ~ milligram order of magnitude; The powder trace feedway that delivery speed is controlled.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of micro powder feedway, comprise powder hopper, pinprick discharge opening is set below powder hopper, vibration pestle is provided with in pinprick discharge opening, described vibration pestle comprises rod body part, and arrange cone shape sharp-pointed portion in the middle of rod body part, cone shape sharp-pointed subordinate's end face diameter is greater than pinprick discharge opening internal diameter; Described vibration pestle lower end is connected with horizontal elastic oscillation transmission lever; The other end of described elastic oscillation transmission lever and rotation knock bar Intermittent Contact, elastic oscillation transmission lever is connected with L shape pipe link near the below of this end (namely with the one end of knocking bar Intermittent Contact rotated), and the other end and the permanent seat of L shape pipe link are articulated and connected; The described bar that knocks is placed in the two ends of revolving bar and the center of revolving bar is connected with the output shaft of stepping motor; The below of described vibration pestle is provided with out funnel.
Adopt said structure, accurately rotative speed is controlled by stepping motor, the pole pair elastic oscillation transmission lever of knocking at driven rotary bar two ends carries out constantly knocking of rule, then transmission of power is given vibration pestle by elastic oscillation transmission lever, thus drive vibration pestle regular up-and-down movement in pinprick discharge opening, rod body part constantly dredges friction to powder, and sharp-pointed portion provides larger droping space for powder, realize vibrating the powder in powder hopper, loose, and drive powder out to enter out funnel from discharge opening, this structure compares similar " microscale feeder " (helix line rotating discharge), " plug machine " phenomenon is avoided from principle, charging times significantly reduces, more convenient operation.Operational throughput is more small, is low to moderate per second or per minute 0 ~ milligram order of magnitude; Delivery speed is controlled.No matter be pinprick or annular space, realize not vibrating (and rocking), not discharging; Large vibration, has more material.And the external diameter owing to adopting the internal diameter of pinprick discharge opening to be greater than vibration pestle, then vibration processes vibration pestle contacts hardly with bottom powder container, avoids powder hopper causes powder tapping not easily discharging phenomenon appearance owing to absorbing vibratory force.
As preferably, described vibration pestle rod body part be positioned at top, sharp-pointed portion sidewall on be provided with some hangnails, adopt this structure, powder quickly discharging can be driven, thus significantly reduce the jolt ramming phenomenon of upper strata heap powder-deposit.
As preferably, the lateral wall in the described tapered portion of powder hopper arranges one deck flexible bellow (as India rubber tube etc.), adopt this structure, even if vibrate the situation that pestle contacts with powder hopper more greatly, once in a while at Oscillation Amplitude, also can realize actv. damping effect, avoid powder hopper to cause the appearance of powder tapping not easily discharging phenomenon owing to absorbing vibratory force.
As preferably, the angle between the bus in described cone shape sharp-pointed portion and height is 10 °, adopts this structure, both fully can drive powder, loose effective, can play shear action simultaneously, reduce resistance to powder.
The utility model can control to knock frequency by the speed adjustment of adjustment stepping motor, thus controls operational throughput; In order to avoid, the employing of powder vibration agglomeration is lower knocks frequency; Such as 0.1 ~ 10Hz.

Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment, the utility model is described in detail.
As shown in accompanying drawing 1-2: a kind of micro powder feedway of the present utility model, comprise powder hopper 1, pinprick discharge opening 2 (namely internal diameter is the aperture in more than 0 to 5mm aperture) is set below powder hopper 1, vibration pestle 3 is provided with in pinprick discharge opening 2, described vibration pestle 3 comprises rod body part 3.1, arrange cone shape sharp-pointed portion 3.2 in the middle of rod body part, cone shape sharp-pointed portion 3.2 lower surface diameter is greater than pinprick discharge opening internal diameter; Described vibration pestle lower end is connected with horizontal elastic oscillation transmission lever 4; The other end of described elastic oscillation transmission lever 4 and rotation knock bar 5 Intermittent Contact, elastic oscillation transmission lever 4 is connected with L shape pipe link 7 near the below of this end, and the other end and the permanent seat 8 of L shape pipe link are articulated and connected; The described bar 5 that knocks is placed in the two ends of revolving bar 6 and the center of revolving bar 6 is connected with the output shaft of stepping motor 9; The below of described vibration pestle 3 is provided with out funnel 10.
Adopt said structure, accurately rotative speed is controlled by stepping motor, the pole pair elastic oscillation transmission lever of knocking at driven rotary bar two ends carries out constantly knocking of rule, then transmission of power is given vibration pestle by elastic oscillation transmission lever, thus drive vibration pestle regular up-and-down movement in pinprick discharge opening, rod body part constantly dredges friction to powder, and sharp-pointed portion provides larger droping space for powder, realize vibrating the powder in powder hopper, loose, and drive powder out to enter out funnel from discharge opening, this structure compares similar " microscale feeder " (helix line rotating discharge), " plug machine " phenomenon is avoided from principle, charging times significantly reduces, more convenient operation.Operational throughput is more small, is low to moderate per second or per minute 0 ~ milligram order of magnitude; Delivery speed is controlled.No matter be pinprick or annular space, realize not vibrating (and rocking), not discharging; Large vibration, has more material.And the external diameter owing to adopting the internal diameter of pinprick discharge opening to be greater than vibration pestle, then vibration processes vibration pestle contacts hardly with bottom powder container, avoids powder hopper causes powder tapping not easily discharging phenomenon appearance owing to absorbing vibratory force.
Vibration pestle described in the utility model 3 rod body part 3.1 be positioned at top, sharp-pointed portion 3.2 sidewall on be provided with some hangnails 3.3, adopt this structure, powder quickly discharging can be driven, thus significantly reduce the jolt ramming phenomenon of upper strata heap powder-deposit.
