Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to containers for various cylindrical oil purifiers, and more specifically, to manufacturing containers suitable for the amount of oil purified at a low cost. The present invention relates to a cylindrical oil purifier container having a structure in which the container is divided into an upper lid part, a J51 body part, and a lower lid part, which has the advantage that the inner surface of the container can be easily cleaned.

(Prior art) The cylindrical container body, which is the main component of various types of oil purifiers such as electrostatic type, filtration type, and electromagnetic type, is open at the upper end and closed at the lower end from the viewpoint of manufacturing. The type that forms the bottom of the container is often used. This is because this type of container can be easily processed by die casting, drawing, etc., and the open upper end can be sealed by attaching a lid, which has the advantage of using soil in terms of manufacturing and processing. however,
When a container of this type in which the bottom is integrated with the container body is used for an oil purifier, there are various problems.

This point will be explained below using an electrostatic oil purifier as an example.

Recently, the cleanliness control of oil used in hydraulic systems and lubrication systems of various industrial equipment has become stricter.For example, when looking at the relationship between the size and number of contaminant particles (dust) in oil, The new oil is NASA class 10-12 (pollution level, NASA 16).
The number of 5 to 15 μs dust particles in 100+aQ according to 38 is 250,000 to 1 million pieces), and the NC machine oil is NASA
Class 7 to 9 (30,000 to 100,000 pieces), NAS for missiles
It is classified as A4 grade (4,000 particles), and the requirements for reducing contaminant particles in oil are becoming increasingly strict. Oil contamination is caused by contaminants (contaminants) in the oil as it is used.
This contamination is caused by the accumulation of equipment wear debris (powder), sludge generated by oil oxidation, and chips on the equipment surface due to cavitation erosion, and this contamination impairs the normal operation of the equipment.

It is well known in the industry that electrostatic oil purifiers are effective in preventing oil contamination.

This type of electrostatic oil purifier is published in Japanese Patent Publications No. 45-35519, No. 47-25610, No. 50-11109, No. 53-
No. 139, No. 57-46898, Publication No. 59-254
No. 88, etc., Yin and Yang mW1 electrode plates are arranged facing each other in an electrostatic oil purification tank (container), and a porous or fibrous dust collector (for example, a collector made of non-woven fabric) is placed between the Yin and Yang electrodes. ), and a passage for oil, which is the liquid to be treated, is formed on both sides of the dust collecting body.

A high voltage (e.g. 10KV -15K) is applied between the negative and positive electrodes.
V) is applied to efficiently capture and remove (+) or (-) charged fine dust in oil onto a dust collector or electrode.

As the electrostatic oil purifier operates, contaminants in the oil become saturated and accumulate on the dust collector and the inner wall of the container, reducing the amount of oil purified and the oil purification efficiency, so it must be cleaned periodically. It is necessary to replace the dust collector and clean the inner wall of the container.

In this case, if the container body of the electrostatic oil purifier is of the conventional type in which the bottom is integrated with the container body, it is extremely difficult to clean the inner surface of the container. Particularly when a high amount of oil is required, the inner surface of the container must be thoroughly cleaned, but this type of container has poor workability and cleaning is often insufficient.

In addition, in this type of container, only one container with a fixed volume can be made with one design or mold, and in order to achieve the necessary and sufficient oil purification capacity, many containers of the same type must be prepared. This leads to high costs. Moreover, when multiple containers with limited capacity are connected and used.

There are many problems, such as problems with the installation location and the amount of work required to connect the pipes.

(Problems to be Solved by the Invention) As a result of intensive study in view of the problems of the oil purifier container described above, the present inventor has developed a cylindrical oil purifier container with an upper lid part, a body part, and a lower lid part. By having a structure that can be divided into parts and freely joined, there is no problem in cleaning the inner surface.

Furthermore, the inventors have discovered that, for example, by joining two body parts together, a container suitable for the amount of oil to be purified can be provided at a low cost, and the present invention has been completed.

[Structure of the invention]

(Means for Solving the Problems) To summarize the present invention, in a cylindrical oil purifier container, the container is divided into an upper lid part, a body part, and a lower lid part, and both open ends of the body part are divided. This invention relates to a container for a cylindrical oil purifier, characterized in that a joint part is provided at the open ends of the upper lid part and the lower lid part, so that the upper lid part, the body part, and the lower lid part can be freely joined. be.

Hereinafter, the configuration of the present invention will be explained in detail.

The cylindrical oil purifiers targeted by the present invention include electrostatic oil purifiers with dust collectors and electrodes inside, filtration oil purifiers with filter media inside, and cylindrical oil purifiers with magnetic fillers. Electromagnetic oil purifier filled inside the container (Electrification is applied to the electromagnetic coil installed on the outer periphery of the container, and the magnetic force generated magnetizes the magnetic filling filled inside the container, thereby eliminating the magnetic non-dissolution in the oil. Any oil purifier having a cylindrical container body, such as one that captures and removes solid matter, may be used.

Each member of the container of the present invention, ie, the body portion, upper and lower lid portions, can be easily formed by casting, drawing, or the like.

In the container of the present invention, since the height of the upper and lower lid parts can be reduced and the shape of the body part is simple, molding of each of these members is very easy.

In the present invention, since the body part is separated from the upper lid part and the lower lid part and configured as independent members, even if the same upper and lower lids are used, by simply changing the length of the body part, for example, the body part can be divided into two parts. You can create containers with arbitrarily different capacities just by joining them together. For example, if you change the diameter of the container to 100
■, 200is, 300+m, 400■, 500■
Even if the oil purifier container is set to the desired capacity, it is possible to manufacture an oil purifier container of any required capacity by simply changing the length of the body, which is easy to manufacture.
