Abstract

PROBLEM TO BE SOLVED: To obtain a device in which oil can be purified with a high degree of purity and which is inexpensive by a method wherein oil flows successively between pipes in layered construction, the opposite ends thereof being sealed, and centrifugal forces are imparted to the oil flowing from the central part, while the oil is flowing between the pipes to remove impurities in the oil. SOLUTION: When a centrifugal power motor 10 is operating and the oil containing impurities is introduced into a centrifugal pipe case 40 from an oil feed pipe 25, the oil, while being subjected to centrifugal forces, flows along each pipe partition over the entire length thereof and flows out of an oil outlet hole to an oil outlet casing cup 35. Then impurities accumulate on the inner wall of each pipe and when feeding oil from the oil feed pipe 25 is stopped at a proper time to remove the impurities, a sliding geared motor 5 is actuated to slide an oil takeout side centrifugal pipe cover 36 and an inner side scraping scoop 12 connected to the cover 36 and an outer side scraping scoop 21 are used to scrape out the impurities and the scoop are returned to their original positions for regeneration.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a compact type which can purify oil such as cooling oil and circulating oil for industrial machines used industrially in a piping system to purify oil with high purity. It is intended to provide an inexpensive device.

[0002]

2. Description of the Related Art Conventionally, the purification of oil such as cooling oil and circulation oil contains chips, powder impurities, colloidal impurities, etc., so that the oil tank is partitioned to remove heavy impurities during the sequential flow. A method of separating, a method of removing impurities by the action of static electricity, a method of pouring oil from the top into a vertical container and applying centrifugal force to the container to let the oil in the center part flow out, and impurities are removed by an oil element. Although there is a method of removing it, except the oil element method, all the apparatuses are large, and the apparatus is in a state where it cannot be said to be oil purification in the piping system, and it has the drawback of being expensive.

Purification with an oil element has drawbacks such as clogging of the element and purification of colloidal impurities in oil are difficult, and there is a problem in durability of the element itself.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, in which a centrifugal pipe formed by rotating a conventional vertical container is installed in a horizontal pipe formed of multiple layers. The oil flows through the multi-layered pipe to increase the total flow distance, and in particular, the oil containing a large amount of impurities at the time of inflow is used as the central part to rotate the purified oil on the outer peripheral part in sequence. By sending it to the outside where gravity is large, the outer diameter of the pipe is reduced and the size of the entire device is reduced.

Further, by providing a scraping spatula so that impurities accumulated inside the pipes of each layer can be automatically discharged, it is possible to inexpensively realize automation by continuous repeated use of the device. .

[0006]

In order to achieve the above object, the present invention provides a method of obtaining a centrifugal force by providing several pipes inside a pipe at intervals of several centimeters, and using both ends of the pipes with lids. Make a sealable state, and insert a small diameter pipe from the inlet side so that oil can be injected inside.

Inside the lid on the outlet side, a scraping spatula attached so as to rub the inner and outer walls of each pipe inside is provided up to the inner surface of the lid on the inlet side, and is connected to the inside of the lid on the outlet side by a connecting rod. Therefore, the impurities accumulated in the pipe can be scraped out by sliding together with the outlet side lid.

[0008]

Therefore, the oil flowing through the small-diameter pipe on the inlet side is subjected to centrifugal force while passing through the pipes provided inside, so that impurities are broken out toward the outside,
While flowing in the inner wall, it flows sequentially and is discharged from the outlet side.

Also, by stopping the inflow of the oil on the input side at a fixed cycle and sliding the lid on the outlet side, the impurities accumulated inside by the scraping spatula are scraped downward from the end portion on the outlet side. The internal impurities can be discharged, and the recycle operation can be performed automatically.
