Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an apparatus for efficiently and purely separating and extracting powder having a specific particle size range from powder having a wide particle size distribution.

In particular, it relates to a filter-type powder separator.
[Background of the Invention] This type of filter-type powder separator uses a filter (hereinafter referred to as a filter) to collect a fluid in which powder is dispersed.

) to classify and separate the powder by passing only the powder with a specific particle size or less. However, although this powder separator can obtain powder with an accurate particle size range, it is inefficient and the filter can become clogged because the liquid in which the powder is dispersed is filtered by gravity. Easy to do. Therefore, a device was developed that filters the liquid containing powder dispersed through the bottom of the filter.

This powder separator is highly efficient and difficult to clog, as exemplified by the one described in Registered Utility Model No. 32496. [Object of the Invention] The present invention relates to an improvement of the above-mentioned powder separator, and aims to provide a powder separator that is more efficient and difficult to estimate.

[Summary of the invention]

The present invention provides a constriction part in the upper part of the tank, a filter is installed on the constriction part, and the tanks equipped with filters for each stage are connected by a pipe,
Finally, a water storage tank is connected, and the liquid containing the powder dispersed therein is allowed to pass from the bottom surface of the filter, and the liquid containing the separated specific powder is stored in the water storage tank. shall be.

[Embodiments of the invention]

An embodiment of the powder separation apparatus of the present invention will be described below with reference to the accompanying drawings.

The accompanying drawing is a schematic diagram of an embodiment of the powder separation apparatus of the present invention.

In the figure, 1 is a water flow pump that creates a flow of water (or liquid) throughout the device, 2 is a feed intake that introduces powder or a liquid in which powder is dispersed, and 3 is a water flow between the mysterious material intake 2 and the water flow. This is a lock that separates the space between the two and prevents liquid from overflowing.

Reference numeral 4 denotes a tank, which is provided with a constriction part 5 at the top, a filter 6 is installed in the constriction part 5, and an ultrasonic transmission device 7 as a vibration means for applying ultrasonic vibration to the filter 6 to prevent glancing. And an ultrasonic generator 8 is installed.

The tank 4 is equipped with a filter 6 for each stage.
are connected by a pipe 9, and the last tank 4 is connected to a water storage tank 12 via a pipe 9, a sample reservoir 11, and a filter 10. In the figure, 13 is a water supply port that supplies liquid prior to over-separation of powder, and 14 is a discharge port that takes out unnecessary liquid. Next, the operation of the powder separator of the present invention in this example will be explained.

First, powder or a liquid in which the powder is dispersed is introduced into the apparatus through the grain intake port 2, and the liquid is supplied through the water supply port 13.

Then, the liquid in which the powder is dispersed flows as shown by the arrow by the water pump 1, and first in the first tank 4, it becomes a distant upward flow due to the upper constriction part 5, and passes through the lower surface of the filter 6. Since the flow of liquid becomes a fast upward flow due to this constriction part 5, the flow rate of the liquid becomes faster and the powder can be separated more efficiently, and the powder adhering to the lower part of the filter 6 can be removed by itself or by its own weight after agglomeration. Because it falls due to
There are very few blinds where filter 6 becomes clogged. Also,
When the filter 6 is vibrated with ultrasonic waves, the powder adhering to the lower part of the filter 6 is promoted to fall, so that the filter 6 is not clogged.

When the above-mentioned liquid passes through the lower surface of the filter 6, only particles with a small particle size selectively pass through the filter 6, while powder with a large particle size sticks to the filter 6 or settles at the bottom of the tank 4. . Next, the fluid that has passed through the filter 6 of the first tank 4 flows into the second tank 4 through the pipe 9, and then passes through the filter 6 in the same manner as described above.
Finally, the liquid passes through the sample reservoir 11 and the filter 10 and accumulates in a water tank 12, and the powder in a specific fleas range is collected from the liquid collected in the water tank 12. [Effects of the Invention] As is clear from the above examples, the powder separator of the present invention has a constriction section at the top of the tank, a filter above the constriction section, and disperses the powder. Since the liquid passes through the bottom of the filter, the flow rate of the upward flow of the liquid increases due to the action of the constriction part, making it possible to separate the powder more efficiently and removing the powder that adheres to the bottom of the filter. Since the particles fall off due to their own weight either alone or after agglomeration, clogging of the filter is extremely rare.

Moreover, since the filter is equipped with a vibration means for vibrating the filter, when the filter is vibrated, powder adhering to the lower part of the filter is promoted to fall, and the filter is not clogged.
