Abstract

PURPOSE:To improve the accuracy of measurement of the supplied quantity of powder in an equipment for continuously supplying the fixed quantity of the powder, by controlling the degree of opening of a valve for a hopper depending on the amount of the powder in the hopper to keep the amount constant. CONSTITUTION:When powder supplied from a butterfly valve 10 has accumulated into contact with the open end of a detection pipe 13 provided in the body 6 of a hopper, air blown off from the open end of the detection pipe is hindered by the powder from flowing, so that the back pressure of the air in the detection pipe rises. The pressure rise is found out by a pressure detection mechanism 15 and applied to a controller 16. In response to the pressure rise signal, the controller 16 supplies an air cylinder 11 with a signal to close the butterfly valve 10. The air cylinder 11 is driven by the signal to shut the valve 10. This series of action keeps constant the quantity of the powder in the hopper 5.

Conventionally, the conventional method for supplying powder with continuous quantitative powder supply equipment is to quantitatively feed the powder stored in a surge bin to a belt conveyor or ejector using a rotary feeder, screw feeder, slat valve, etc. Met. However, these methods tend to cause a flash phenomenon of the powder in the surge bin and a phenomenon in which coarse particles mixed in the powder such as gold are caught, and when these phenomena occur, it is difficult to weigh the powder. There were drawbacks such as the inability to control the process at all. In addition, particularly in the case where a screw feeder is used as the feeder, the discharge amount of the screw feeder varies depending on the layer thickness of the powder in the surge bin, which makes it difficult to supply the powder in a constant quantity.

Next, the operation of the fixed quantity supply mechanism configured in this way will be explained as follows.
The diagram will be explained. The powder in the surge bin 1 passes through the inflow pipe 7, the butterfly valve lO, and the hopper body 6.
It is deposited on the bell) 17 of the belt conveyor 8 inside. When the powder accumulates until it contacts the open end of the detection tube 13 provided in the hopper body 6, the flow of air blown out from the open end of the detection tube 13 is blocked by the powder.
Therefore, the back pressure of the air inside the detection tube 13 increases.

This pressure increase is detected by the pressure detection mechanism 15 and sent to the controller 16. The controller 16 uses this pressure increase signal to apply a butterfly valve 10t- to the air cylinder 11.
A pulp closing signal corresponding to this pressure increase signal is sent to close the pulp. The air cylinder 11 operates according to this signal,
Close the butterfly valve 10'. Through this series of operations, the amount of powder in the hopper 5 is kept constant. Then,
When the belt conveyor 8 begins to move and a certain amount of powder begins to be transferred through the cutting outlet 9 of the hopper body 6, the amount of powder in the hopper 5 decreases, and the open end of the detection tube 13 becomes larger than the powder. ]
The air pressure inside the detection tube 13 decreases. This pressure decrease is similarly detected by the pressure detection mechanism 15 and sent to the controller 16 as a pressure decrease signal. The controller 16 sends a pulp open signal to the air cylinder 11 based on this signal. The air cylinder 11 opens the butterfly valve 10 to the roundness level in response to the pressure drop signal according to the pulp open signal.

When the butterfly valve 10 is opened, the powder in the surge bin 1 flows into the hopper 5. Here, the powder is in the detection tube 1.
If the powder is deposited until it contacts the open end of No. 3, the inflow of the powder will be suppressed as described above. In this way, hopper 5
Although part of the powder is constantly transferred by the belt conveyor 8, the amount of powder inside is always kept constant. Therefore, even if the phenomenon of 7:L of powder occurs in the surge bin 1 and a large amount of powder starts to flow at once, the amount of powder in the hopper 5 will always be at the level of the open end of the detection tube 13. The butterfly valve prevents the flash phenomenon from spreading to the belt conveyor 8 by maintaining a constant amount determined by the butterfly valve. Since 10't is used, coarse particles will not be caught.

In this way, when the powder begins to be transferred onto the belt conveyor 8, a pulse signal representing the transportation amount determined by the transportation amount totalizer 20 is inputted to the FA converter 21. The FA converter 21 converts the pulse signal into an analog/pg signal, which is input to the controller 22 . The controller 22 mo obtains a signal corresponding to the difference between the measured transport amount and the supply capacity set value, and this signal is input to the speed control mechanism 23, and the signal is inputted to the speed control mechanism 23 to indicate that the difference between the measured transport amount and the supply capacity set value is zero. The traveling speed of the belt conveyor 80 is adjusted so that. Through these series of operations, the powder 71) transferred on the belt conveyor 8 is always kept constant. Note that the supply capacity setting value of the powder continuous quantitative supply device shown in this example fluctuates from moment to moment. In such a case, the supply capacity setting value may be used as the opening degree reference signal of the butterfly valve 10, and in this case, the quantification of the powder in the hole 5 is further improved.

FIG. 2 shows a second example of a continuous quantitative supply of powder using the quantitative supply mechanism of the present invention, and the same components as those shown in FIG. omitted. The powder continuous quantitative supply device of this example uses a screw feeder 31 as a feeder, and the powder discharged from the screw feeder 31 is pneumatically transported by an ejector 32. In addition, in order to prevent the pressure of the high-pressure air for pneumatic transport sent to the ejector 32 from causing fluctuations in the pressure change of the detection tube 13, the screw pitch of the screw feeder 31 is gradually narrowed to transfer the powder to the screw feeder 31. The compressed powder is used to block the pressure t-.

The explanation will be omitted. In this example, the pressure of high-pressure air in the ejector 32 is shut off by a two-stage lock hopper 33 provided at the input port 2 of the surge bin 10, so as to prevent pressure changes in the detection tube 13 from changing.

As explained above, the quantitative feeding mechanism of the present invention includes a hopper between the surge bin and the feeder, and detects the pulp that controls the powder flowing into the hopper from the surge bin and the amount of powder stored in the hopper. A detection mechanism is provided, and a pulp control mechanism is further provided that controls the opening degree of the valve based on the nine powder amount signals detected by this detection mechanism, so that the amount of powder stored in the hopper is only a part of the amount of powder stored in the hopper. 9 is always constant regardless of whether it is always sent to the feeder.
, the accuracy of measuring the powder supply amount of the powder continuous quantitative supply device is improved. Furthermore, even if a flash phenomenon occurs in the powder in the surge bin, this does not spread to the feeder, and the powder is supplied to the feeder as usual. 1 more
Even if coarse particles such as metal objects are mixed into the powder, using a butterfly valve for pulp will prevent the coarse particles from getting caught in the pulp. The disadvantage that the discharge amount of the screw feeder varies depending on the thickness of the powder layer in the surge bin is also solved.
