Abstract

A particle collecting system, when attached to a vacuum/blower unit, enables the collection of particles eg, seeds, insects, plants, into a quickly detachable vessel 22. No nets bags or screens are required for the collection of the particles. Air sucked in from atmosphere is caused to rotate by vanes 18 and entrains particles on surface 21. Particle laden air is further rotated by vanes 14. The separated air is drawn through a sieve 12 and over a vane airspeed indicator 11 to the vacuum/blower unit, while the separated particles fall into collection vessel 22. <IMAGE>

Description

VACUUM PARTICLE COLLECTOR This invention relates to a vacuum particle collector which may be used to collect a wide range of particle sizes including biological material such as seeds,insects and plant matter.
A range of portable vacuum particle collectors are available in which the particles are collected in a bag or net through which the air passes prior to being exhausted to the atmosphere.
It is an object of the present invention to provide an improved particle collecting system.
According to the present invention there is provided a system of tubes and vanes that cause the entrained air and particles to rotate to cause a vortex until an expansion chamber is reached.
The entrained particles are then deposited and collected in a quickly detachable vessel.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings.
Drawing 1/2 shows a sectional view of the apparatus; Drawing 2/2 shows plan views of components shown in page 1/2; Referring to the drawing 1/2 air is sucked through the gauze mesh surrounding anulus 20 and is caused to rotate by the inclined vanes 18 and entrain any paticles that are on the surface area 21.
The particle laden air then passes over vanes 14 to further develop the vortex until it reaches the expansion chamber 13.
The reduced velocity of the air at this stage effects separation of the particulate from the ascending air stream while the rotary action of air in the expansion chamber sweeps the particles into the collecting vessel 22. Air from the expansion chamber is drawn through a course mesh safety sieve 12 and over the vane airspeed indicator 11 before pasing through the impeller of an attached vac/blower unit not shown. The air is then exhausted to the atmosphere.
The vanes 18 may be ommited, but in that case, vanes at position 14 are essential to the effective collection of particulate.
Drawing 2/2 Fig 1 shows a plan view of the airflow indicator 11.
Drawing 2/2 Fig 2 shows the six 30 degree tilted vane unit 14 shown in sectional form in drawings 1/2. These vanes may also consist of two close coupled three bladed units fitted in series and set 60 degrees out of phase.
Drawing 2/2 Fig 3 shows the twelve 45 degree set vanes 18 attached to tube 19 shown also in drawings 1/2.
Drawing 2/2 Fig 3 also shows a deflector vane 23 fitted below the twelve vanes and protruding into the area of tube 15 to assist in entraining very light particles.
The collecting vessel 22 must be of rigid construction but can be of almost any shape or size.
It is shown attached to the 'D' shaped particle collector section attached to the expansion chamber 13.
An air tight seal must be effected between the expansion chamber 13 and the collecting vessel 22.

Claims (5)

1 A particle collector that permits the retention of the particles without an in-the-line collecting bag or screen.
2 A quickly detachable external cozycollecting vessel that permits immediate examination of the collected material. In the case of living organisms they may be examined and returned to their habitat.
3 A series of perforated screens fitted in the collecting vessel enables size based fractions of particulate to be obtained.
4 The airflow is not noticeably affected by the number of particles collected.
5 Staged vanes allow large particles to be collected.
