Description

[Detailed Description of the Invention] Industrial field of use The present invention relates to a separation device that removes non-magnetic chips or magnetic chips contained in coolant liquid for machine tools, etc. and reuses the liquid. When scraping off the chips that settled on the inclined frame part with a scraper to the outside of the tank, a guide plate is installed with a narrower interval for the scraping surface from the bottom of the inclined frame part to the discharge port. The present invention relates to a separating device in which scraping can be scraped and discharged regardless of the shape of the chips by pressing and compressing the scraped chips with a scraper to improve the carrying-out efficiency.

BACKGROUND ART A large amount of so-called coolant liquid is used to cool cutting tools and machining materials in machine tools and to remove generated chips. To reuse this, a large amount of mixed chips of various shapes are used. Need to be removed from the coolant,
Many filter bodies and separation devices for cleaning a coolant liquid that has become a polluted liquid due to chips and the like have been proposed so far.

In particular, the filtering device for coolant such as non-magnetic chips generated during the processing of aluminum materials and plastics materials is composed of two tanks, a dirty tank and a clean tank, between which filters such as nets and paper are placed. There has been proposed a configuration in which a so-called filter body is used for cleaning, such as a configuration in which slit members are used, a slit material is arranged in multiple stages, or members having a required shape are arranged in multiple stages.

Further, a configuration utilizing the fact that non-magnetic chips are precipitated in the coolant, that is, by introducing a polluted coolant into the precipitation tank, the chips precipitated at the bottom can be scraped out of the tank and discharged. There is a separation device equipped with a so-called flying scraper conveyor, which is most frequently used in the field of the filtration and separation device.

Problems of the prior art Separation device (1) having a settling tank equipped with a flying scraper conveyor has a settling tank (2) at a required angle from one side of its horizontal bottom (3) as shown in FIG. An inclined frame part (4) having a discharge port 5 at the end is continuously provided, and the inclined frame part and the introduction port (6) side of the settling tank (2) are provided.
(4) Stretching with a sprocket (7) between the upper ends, a scraper (9) provided on a rotatably arranged chain (8), etc., to remove the chips that have settled on the bottom (3). And a structure capable of scraping and discharging by moving on the inclined frame part (4) and discharging from the discharge port (5) to the outside of the device (1).

The shape of the chips that flow into the settling tank (2) together with the coolant is
There are various shapes depending on the difference in tools such as a cutting tool, a drill, a grindstone, etc., and depending on the processing conditions, the desired accuracy and the surface roughness.

In such a separating device (1), chips and particles in the form of particles and flakes can be easily discharged, but as shown in FIG. 3, curled rods (Fig. A) and filaments are entangled and spherical. The scraps (Fig. B) and plates (Fig. C) are difficult to discharge because they fall from the scraper when scraping, or come in contact with the circulating return scraper.
There was a problem of remaining in (2).

DISCLOSURE OF THE INVENTION An object of the present invention is to provide a separating device having a settling tank equipped with a flying scraper conveyor, which can be scraped and discharged regardless of the shape and magnetism of the chips and has improved carrying-out efficiency.

Configuration of the Invention This invention has a settling tank that has an inclined frame part that continuously rises from one side of the bottom part, and a settling tank and a flying scraper conveyor that is rotatably arranged inside the inclined frame part. In a separation device that can scrape the chips settled on the bottom of the tank to the outside of the device and discharge them, the scraps scraped by a scraper with a narrow interval for the scraping surface from the bottom of the settling tank on the inclined frame to the discharge port. The separating device is characterized in that a guide plate capable of pressing and compressing is disposed in the device.

Disclosure of the Invention Based on the Drawings FIG. 1 is a schematic vertical sectional front view showing the configuration of a separating device according to the invention.

Structure The separation device (10) according to the present invention has a settling tank (11) of the main body arranged in a pit provided under the floor of a processing factory, for example.
The horizontal bottom of the settling tank (11) continuously rises from one side thereof at a required angle to form an inclined frame portion (12) having a discharge port (14) at the end.

Inside the settling tank (11) and the inclined frame part (12), the settling tank (11)
The sprocket (17) (17) and a sprocket (not shown) are stretched and rotatably arranged between the inlet (12) side of the upper part of the machine and the upper end of the inclined frame part (13) and arranged at a required interval.
For example, the chain (18) of two threads is rotatably driven by a geared motor (not shown) arranged at the upper end of the inclined frame portion (13), and is mounted between the two chains (18) and fixed. A large number of scrapers (19) arranged at intervals contact the bottom part (15) of the settling tank (11) and the scraping surface (16) of the inclined frame part (13) to collect the chips deposited on the bottom part (15). A so-called flying scraper conveyor having a structure capable of being discharged to the outside of the tank is provided.

Furthermore, in the separating device (10), a scraping surface (16) from the bottom (15) side of the settling tank (11) of the inclined frame part (13) to the discharge port (14).
A guide plate (20) is provided for the.

Actions / effects The guide plate (20) is located on the bottom (15) of the settling tank (11) from the required position above the chain (18) to the inclined frame part.
With respect to the scraping surface (16) near the discharge port (14) of (13), it is arranged so as to narrow the interval with the scraping surface (16) until a position close to the chain (18), The scraper (19) has a function of temporarily contacting the chips (21) that are scraped and carried out, and then pressing against the scraping surface (16) and further compressing.

As the guide plate (20), not only a flat plate shape but also a grid shape can be used.

The chips (21) settled on the bottom part (15) of the settling tank (11) are slidably moved to the scraping surface (16) by each scraper (19) of the circulating flying scraper conveyor, and further scraping surface ( 16) A guide plate that moves up, but is conventionally curled, such as curled rods that easily fall from the scraper when scraping, spheres in which filaments are entangled, plates, etc. are guide plates. (20) is abutted for a while, then pressed against the scraping surface (16) and further compressed, so it is scraped out from the scraper (19) without falling, and is sent from the discharge port (14) to the chip receiving box (22). ).

That is, the separation device (10) according to the present invention comprises a settling tank (11).
The scraps (2) conveyed by the scraper (19) at the horizontal bottom (15) of the
In 1), it is possible to discharge chips of various shapes, which were previously impossible to discharge, by being surely scraped up and discharged.

The separation device (10) of FIG. 1 is designed to scrape and discharge non-magnetic chips, but even if the processed material is magnetic, chips as shown in FIGS. 3 a to 3 c are generated. Therefore, in the configuration of FIG. 1, the bottom part (15) of the settling tank (11) and the inclined frame part (13)
By arranging a magnet on the back side of the machine, not only the natural precipitation of non-magnetic chips but also the forced precipitation of magnetic chips can be achieved by the flying scraper conveyor. It is possible to scrape and discharge.
