[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a granular material collector.
[0002]
[Prior art]
Heretofore, the following are known as this type of particulate collector.
A cylindrical main body having a top wall in which a granular material inlet is formed, a lower tapered portion having a granular outlet at a lower portion, and a gas outlet at a side peripheral wall, and the cylindrical main body The gas outlet is provided so as to define the gas outlet with the granular material inlet and the granular material outlet so as to have a predetermined interval therebetween, and the passage of the granular material of the set size is not allowed. It is known to have a filter that allows the passage of water and an open / close lid provided at the outlet of the granular material of the cylindrical body.
[0003]
[Operation of conventional technology]
The operation of the conventional technique will be described below.
Connect the granular material storage source (having a gas inlet) where the granular material is stored at the granular material inlet, connect the suction port of the gas suction device to the gas outlet, and open and close after such preparation If the gas suction device is operated after closing the outlet of the granular material with the lid, the following actions are performed.
Since the inside of the powder collector becomes negative pressure, the powder flows into the powder collector together with the gas from the powder inlet, the gas goes out from the gas outlet, and the powder is powder. Accumulated in the particle collector. And after stopping a gas suction device, the granular material in a granular material collector is discharged | emitted from a granular material exit by opening an on-off valve.
[0004]
[Disadvantages of the prior art]
The conventional powder collector has the following drawbacks.
Virgin raw materials such as heavy pellets (generally having a high apparent density) are collected by the conventional powder collector, and then opened by opening the on-off valve. (In this specification, a light-weight granule is a gas having a predetermined flow rate from the bottom to the top and is swung up by the gas flow and does not fall under its own weight, or (Refer to powder particles that are difficult to fall.) (In general, the apparent density is small), the light-weight particles supplied from the particle inlet to the particle collector are placed at the gas outlet. It is attached to and accumulated on the surface of the filter by riding the gas flow. And after a certain amount of lightweight powder has accumulated in the powder collector, even if the gas suction device is stopped and the on-off valve is opened to discharge the lightweight powder, the lightweight powder will remain. Because it adheres to and accumulates on the surface of the filter, and the lower part of the cylindrical body is a tapered part below the concavity and the wall surface resistance is high, it is possible to reliably discharge lightweight powder particles under its own weight. There was a drawback of not.
In addition, since reused raw materials pulverized to reuse used synthetic resin products often become lightweight powder particles, promoting the reuse of used synthetic resin products from the viewpoint of protecting the global environment. For this reason, it is indispensable to eliminate the drawbacks.
[0005]
[Means for Solving the Problems]
The present invention employs the following means in order to eliminate the above disadvantages.
The invention of claim 1 has a top wall in the upper part, the lower part serves as a granule outlet, a granule inlet is formed in the lower part of the side peripheral wall, and a gas outlet is formed in the upper part or top wall of the side peripheral wall. And the passage of a granular material of a set size provided so that the gas outlet is separated from the granular material inlet and the granular material outlet in the cylindrical main body. A taper tube that extends downward and includes a filter that allows gas to pass, an open / close lid provided at the outlet of the granular material of the cylindrical main body, and a granular material pressing tool that is movable up and down within the tapered cylinder. It has a gas flow to the lower part of the taper tube from the powder particle inlet by the gas flow, the gas is discharged from the gas outlet, and the powder particle is moved above the taper tube to the upper part of the taper tube And the granular material accumulated at the top of the taper tube is pushed by the granular material pressing tool. In which it was to be lowered.
[0006]
【The invention's effect】
The present invention has the following effects by the configuration as described above.
After closing the open / close lid, the lightweight powder is introduced from the lower powder inlet to the lower part of the tapered cylinder, and the gas is discharged from the upper gas outlet so that the lightweight powder flows into the gas flow. By moving the upper part of the tapered cylinder from the upper part of the tapered cylinder, the lighter granular substance tends to become denser toward the upper part and sparse toward the lower part. In addition, the filter that separates the light-weight granular material is a tapered tube that expands downward, and after opening the opening / closing lid, the light-weight granular material accumulated on the upper portion of the tapered tube by the granular material pressing tool Due to the synergistic effect of pushing down, the light-weight granular material stored in the tapered cylinder can be reliably discharged from the granular material outlet.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
The granular material collector 1 has a top wall 2 at the upper part, the lower part serves as a granular material outlet 3, and a granular material inlet 4 is formed at the lower part of the side peripheral wall. Alternatively, a cylindrical main body 7 having a gas outlet 5 formed on the top wall 2) and the gas outlet 5 are provided in the cylindrical main body 7 so as to be separated from the granular material inlet 4 and the granular material outlet 3. A taper tube 8 having a downward expansion and made of a filter that does not allow the passage of a granular material of a set size and does not allow the passage of gas; and an opening / closing lid 11 provided at the granular material outlet 3 of the cylindrical main body 7. In addition, it has a powder body pressing tool 12 of an arbitrary shape provided so as to be movable up and down in the tapered cylinder 8.
