Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for separating particles being transported in a fluid stream from the fluid stream and discharging said particles out of the downstream stream.

Conventionally, when transporting particles by mixing them into a gas or liquid stream,
A large separator such as a cyclone is required as a device to separate the particles from the fluid stream. Furthermore, when discharging the pre-1'i3 particles out of the separator, an airtight discharge machine such as a rotary feeder is required. However, the rotary feeder also has the drawback of frequent failures such as malfunction due to particle entrapment and poor airtightness due to wear.

The present invention provides a particle separating and discharging device that has both the function of separating particles from a fluid stream and the function of discharging the particles to the outside of the fluid stream, and has a very compact structure and a structure with few failures. The purpose is to

To explain the present invention based on drawings of embodiments, in FIGS. 1 and 2, a cylindrical portion 1111i1/ with one side open is open, and the other side is the shaft of the motor 2. is fixed. The minute 1ife/ has a large number of small holes l/ on the circumferential side, a brush 12 is planted around the entire circumference of the end of the open side, and the unopened side has a collar 13. ing.

Fixed 1i! 3 has a slit-shaped particle injection port 3/ on its circumferential side. A side plate to which the motor 2 is fixed is attached to one side of the fixed cylinder 3, and a so-called granule inflow pipe S through which fluid mixed with granules flows is attached to the other side. . Fixing W of the inflow pipe S of this granule
The part facing J3 has a double pipe structure, and the name of the so-called fluid outflow pipe through which the fluid flows out after the granules are separated is written inside the inlet pipe S of the granules. The opening surface of this fluid inflow pipe B is 11! The brush 12 is in close contact with the end of the opening. Although this brush 12 has a sealing function to prevent particles from flowing into the fluid outflow pipe 6, it does not need to be a brush as long as it has a similar function.

In the apparatus configured as described above, a hose j communicating with a suction blower is connected to the fluid outflow pipe B, and a hose 7 having a suction nozzle attached to the tip is connected to the granule inflow pipe S.
is connected, the operation of the suction blower causes the suction nozzle to flow through the hose 7 and the granule inflow pipe 51 minutes 111.
An atmospheric flow is generated through the small hole Q/, the fluid outflow pipe 6, and the hose g to the suction blower. Therefore, when the particles are sucked together with the air from the suction nozzle, the large and heavy particles cannot pass through the small hole of 1ml Fi due to rotation, and are instead blown away by the lit cylinder. The liquid is then injected out of the fixed cylinder 3 from the injection port 3/ of the fixed cylinder 3. Note that since the pressure inside the stationary 1ll3 is below atmospheric pressure, the atmosphere flows in from the injection port 3 and prevents the injection of the particles.
There is no problem as long as sufficient centrifugal force, or speed, is applied to make the object fly out. FIG. 3 shows that a vane plate/g is provided on the outside of the circumferential side of the cylinder in order to increase the centrifugal force acting on the grains. When the centrifugal force acting on the granules increases and the speed of the granules increases due to the above measures, the amount of granules injected per unit time remains the same even if the opening area of the injection port 31 of the fixed fI3 is reduced. , - Due to the reduction in the opening area of the injection port 31, the amount of air flowing from the injection port 31 into the inner wall of the fixed cylinder 3 is reduced, and the amount of air sucked from the suction nozzle is equal to the reduced amount. Since this increases, the amount of particles transferred can be increased. Note that the particle size of the particles that can be separated by the separation tube 1 can be set to an arbitrary particle size by increasing or decreasing the opening area of the small hole // of the separation tube 1 and by increasing or decreasing the circumferential speed of the circumferential side surface.

The above describes an embodiment of the present invention in which the particles are separated from the atmospheric flow and injected out of the atmospheric flow when the particles are suctioned and transferred by the atmospheric flow. It may also be used as a means of separating the particles from the atmospheric flow and ejecting it out of the atmospheric flow during pumping. Furthermore, the present invention can be used as a means for separating particles from a mixed flow of particles and gas or liquid other than the atmosphere and injecting the separated particles out of the fluid flow.

As described above, the present invention has both the function of separating particles from a fluid stream and the function of discharging the particles to the outside of the fluid stream, and is very compact.Moreover, the structure is simple, there are few failures, and it is portable. Ideal for separating and injecting granules.
