Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sludge recovery device that collects cutting powder in cutting water generated in a high-pressure water cutting machine and purifies the cutting water so that it can be reused. The present invention relates to a sludge recovery device for a high-pressure water cutter, which has a structure to be scraped out and which is compact and does not use a conventional paper filter.

[0002]

[Prior Art]

 High-pressure water cutters, which perform cutting and grinding with high-pressure or ultra-high-pressure water, are used in various processing and manufacturing industries today because their equipment is relatively small and noise and dust are unlikely to occur. The cutting water used in the high-pressure water cutting machine contains cutting powder during processing, so it cannot be reused or drained without separating and collecting this cutting powder.

[0003]

[Problems to be solved by the device]

 Conventionally, a paper filter was used to process the cutting water after processing with such a high-pressure water cutting machine, that is, to separate and collect cutting powder. Despite being at most 40 liters per minute, the cutting powder is fine particles, so the amount of paper filters used increases, which not only increases the so-called running cost but also wastes paper resources.

As a device for recovering sludge from cutting water of a high-pressure water cutter, cutting powder is easily atomized because high-pressure water is used, and a paper filter is optimal for recovering cutting powder in a short time. However, the long-time sinking type recovery device had a large water tank, and the high-pressure water cutting machine was originally small in size, which made it unsuitable.

This invention is a sludge for a high-pressure water cutting machine, which does not use a paper filter when processing cutting water in a high-pressure water cutting machine, and has a small installation area and excellent recovery efficiency even in a sinking type recovery device. The purpose is to provide a recovery device.

[Means for Solving the Problems]

 This invention has multiple water tanks for precipitation in which the bottom plate has a concave arc surface with a required radius, and it overflows from the tank into which cutting water flows into other tanks in sequence and collects the cutting water by the overflow water from the final tank. This is not possible, but the sludge recovery device for a high-pressure water cutting machine is characterized in that the rotary shaft of a rotary scraper that scrapes out the sludge settled on the bottom plate of each water tank is arranged at the center of a predetermined arc of the bottom plate.

In the present invention, the flow of cutting water to be treated is carried out by arranging a plurality of water tanks for precipitation in parallel and sequentially overflowing, that is, overflowing. The cutting water introduced into the first water tank is the same as in the embodiment. The water tank overflows into the adjacent second water tank, and the overflow water from the second water tank is collected so that the water overflows sequentially, and the water tank can be arranged as long as the installation area can be reduced.

In this invention, since the sludge that has settled out is scraped out of the tank with a rotary scraper at the bottom of the water tank, a scraper is provided at the tip of a rotating rod having a required diameter as shown in the embodiment, and this is the bottom of the water tank. The bottom plate is formed with a concave arc surface with a required radius so that it can slide and move, and the configuration of the rotary scraper is selected according to the arrangement and size of the water tank, and the bottom shape of the water tank is accordingly selected. Should be decided.

[0009]

[Action]

 This invention has a structure in which sludge is submerged in a plurality of overflow type water tanks and is scraped out of the tank by a rotary scraper, which makes it possible to make the installation space small and to have an extremely simple structure. It is a sludge recovery device that can efficiently scrape out the sludge that has settled in, and is suitable for the processing of cutting water in a high-pressure water cutting machine.

【Example】

 FIG. 1 is a vertical sectional front view showing an embodiment of a sludge recovery device according to the present invention, and FIG. 2 is a vertical sectional side view. In the first water tank 1 and the second water tank 2 for settling the sludge, the bottom plate 4 placed on the base 3 has a concave arc surface with a required radius, and the upper opening surface has a rectangular water tank 5 at the center. The partition plate 6 is formed by dividing it into two tanks having a rectangular upper opening surface of a wide width and a narrow width. In addition, the used cutting water flows in through the inlet 7 on the side surface of the first water tank 1, overflows from the cutout portion 8 of the partition plate 6 and flows into the adjacent second water tank 2, and the front surface of the second water tank 2 further. It is an overflow type water tank in which cutting water is collected from an overflow port 9 provided on a wall.

The rotary scraper 10 is mounted on a rotary shaft 12 that is rotatably driven via a chain by the power of an electric motor 11 mounted on the base 3 while being pivotally supported on the upper end of a common water tank 4. However, it has a structure in which a scraper 14 having a width corresponding to the bottom plate width of each of the water tanks 1 and 2 is provided at the tip of an arm 13 of a required length erected on the rotating shaft 12. Here, although it has a simple structure in which scrapers are provided at both ends of one rotary rod, for example, the arm 13 can be expanded and contracted so that the arm 13 has a required length when it is inside the water tank 5, In some cases, the arm length can be shortened to lower the height of the cover 20 provided on the water tank 5, and various configurations using known mechanical mechanisms can be adopted.

In the above-mentioned configuration, the cutting water discharged from the high-pressure water cutter enters the first water tank 1 through the introduction port 7, then flows into the second water tank 2, and is mixed while being collected from the overflow port 9. The sludge settles and settles on the bottom plates of the water tanks 1 and 2, and can be collected as purified overflow water.

Sludge that has settled on the bottom plates of the water tanks 1 and 2 is scraped out of the water tanks 1 and 2 by a rotary scraper 10 that rotates at a constant speed or rotates intermittently, as shown in FIG. The bottom plate 4 of the water tank 5 continuously rises to one side and serves as an upper end, and sludge scraped up by the scraper 14 rotating and sliding on the bottom plate 4 falls from the upper end and is collected in the sludge receiver 15. It Also, in order to prevent the sludge attached to the scraper 14 that has come out of the water tank 5 from falling again, the sludge on the surface of the scraper 14 is scraped off by a scraping tool 16 that is separately mounted with one end pivotally supported near the upper end. Consist of the composition.
