[Industrial applications]

 The present invention purifies the liquid by collecting oils and floating scum floating on the liquid surface of the coolant aqueous solution or cleaning liquid by adsorbing them on a rope that floats on the liquid surface and rotates endlessly. The present invention relates to a rope type liquid cleaning device.

[0002]

[Prior Art]

 Conventionally, as a device for collecting and removing oil and floating scum floating on the liquid surface of a liquid such as an aqueous solution for a coolant or a cleaning liquid, the collecting means is a cloth or a rubber or chain type flat belt. There is a so-called rope-type liquid cleaning device (oil skimmer) that uses a rope that has an adsorptive property.

[0003] For example, the applicant of the present application has two driving ropes, which are endless trapping ropes having a circular cross section and having adsorption properties for oils, floating scum, etc., which are arranged at left and right intervals above the liquid surface. It is hung on a pulley for endless rotation so that the lower part floats above the liquid surface, and removes oil and scum attached to the rope on the horizontally moving part between both pulleys. A liquid cleaning device having a structure provided with scraping means has been proposed (Japanese Utility Model Laid-Open No. 61-191198).

[0004]

[Problems to be solved by the device]

 The rope type liquid cleaning device proposed above has two pulleys for endless rotation of the rope and removes oil and scum adhering to the rope at the horizontal movement part. There was a problem that the overall width became large and the size became large, and the size of the liquid tank that could be equipped with this was restricted.

Therefore, the inventor of the present invention intends to reduce the size of the entire apparatus by using one pulley for endless rotation of the collecting rope floating on the liquid surface. In this case, the rope is only hung on one drive pulley, so at the rising part of the rope that is pulled up by the pulley, scrape means such as oil and scum adhering to the peripheral surface of the rope can be removed. It is necessary to provide.

However, as the scraping means, as shown in the above-mentioned proposed liquid cleaning apparatus and the like, a simple plate-like scraping having a semicircular cutout portion that can be brought into contact with the peripheral surface of the rope. If the collecting members are arranged on both the upper and lower sides, the oil and scum scraped off by this may fall to the liquid surface and cannot be collected as it is.

In view of the above, the present invention aims to reduce the size of the entire device by providing one driving furry for endlessly rotating the collecting rope, and to prevent oil, scum, and the like from rising in the rope. The present invention provides a liquid cleaning device that can be surely scraped and collected, and further provides a liquid cleaning device that can be scraped and collected without damaging the rope surface.

[Means for Solving the Problems]

 The present invention is a rope-type liquid cleaning apparatus for collecting and recovering oils and floating scum floating on the liquid surface of a liquid tank. As a means for solving the above problems, oils and floating scum An endless collection rope with a circular cross-section that can adsorb, etc., is hung on a single drive pulley located above the liquid surface, and can be endlessly rotated with the lower part floating above the liquid surface. The part of the rising part of the collecting rope from the liquid surface by the drive pulley has a scraping means at the tip part for scraping oil and scum adhering to the peripheral surface of the rope. In addition, a scraping and collecting guide made up of a circular pipe or the like, which can guide the scraped oils and scum to the discharge and collecting means below, is arranged with the tip end facing up.

Further, as the scraping and collecting guide, the tip portion is made of a circular tube having a half-divided tubular shape with one half portion cut off, and the tip portion of the half-divided tubular member is in a state where the tip portion is on the upper side. And a scraping member made of rubber, which has a cutout portion through which the collecting rope can pass, and has a through hole through which the rope can slidably pass and which is smaller in diameter than the cutout portion. It is preferable that the oil and scum scraped off by the above are obliquely arranged so as to flow through the lower circular pipe portion to the discharge and recovery means below.

[0010]

[Action]

 According to the rope type liquid cleaning apparatus of the present invention described above, the lower part of the collecting rope suspended on the driving pulley is floated on the liquid surface with respect to the liquid in the liquid tank containing oil and floating scum. In this state, by rotating the drive pulley, one end of the collecting rope is pulled up from the liquid level to move upward, and continuously, so that it is fed again below the liquid level from the other hanging part. Rotate endlessly.

At this time, in the lower part of the collecting rope that floats on the liquid surface, floating oils, scum, and the like are attached to the peripheral surface of the rope and are pulled up from the liquid surface to rise. Oil and scum that have reached the portion of the scraping and collecting guide provided on a part of the ascending portion, pass through the portion of the scraping means at the tip of the scraping and collecting guide, and adhere to the peripheral surface of the rope While being scraped by the scraping means, it is dropped through the scraping and collecting guide to the lower discharge collecting means and is collected.

In particular, the scraping and collecting guide is made of a circular tube whose tip is formed in a half-split tube as claimed in claim 2, and the collection rope has a margin at the tip of the half-split tube. When a rubber scraping member is provided that has a cutout that can pass through and that has a through hole through which the rope can slide and contact is smaller than the cutout, if the scraping member is attached to the peripheral surface of the rope, Due to the elastic contact, the above-mentioned scraping action is performed well and the rope surface is not damaged.

Moreover, since the scraping and collecting guide is arranged obliquely with the tip end of the half-tube shape facing upwards, the oil and scum scraped off as described above have a tip shape of the half-tube shape. It will surely flow into the circular pipe part that is inclined along the inner surface of the part, and will be recovered from the discharge recovery means below.
