Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for cleaning long square pipes.

[Conventional technology]

As is well known, surface treatment in high-mix, low-volume production depends on the type, size, and shape of the material of the article.

The quantity etc. is not constant and varies widely. For example, the types of materials include steel and stainless steel.

Copper or copper alloy, aluminum or aluminum alloy, titanium or titanium alloy, iron-nickel alloy, iron-nickel-cobalt alloy, magnesium or magnesium alloy, molybdenum or molybdenum alloy, etc., and the shape is 1 cylinder, 1 box, 2 circles, pipe, Square pipes, etc., in terms of size, from small ones like svezers to large ones like electronic computer structures, from short pipes to long pipes, etc.

A characteristic of high-mix, low-volume production factories is that the quantity ranges from one to several.

Before production, the type of material of the article mentioned above.

We are considering the size, shape, quantity, and surface treatment specifications of the tank to be treated, as well as the treatment process.

However, the size and quantity of the processing tank are determined by the type of material, quantity, and surface treatment specifications of the article, and the shape and shape of the article. It is common that no consideration is given to the treatment tank, and that all types of articles are treated in the same treatment tank and in the same treatment process.

They are processed using the same method.

For example, items such as long rectangular pipes that cannot fit into the processing tank are not processed at once after consideration, but half of the items are immersed in the processing tank, and then half of the remaining material is immersed in the processing tank. We are implementing all of these methods.

Furthermore, since large cylindrical articles cannot be treated in the plating pretreatment process in the tank, there are cases where they are treated outside the tank and only 9 pieces are immersed in the tank.

Therefore, considering the treatment tank and treatment process in consideration of the shape of the article contributes to improving its quality and is directly linked to improving its physiological properties.

[Problem that the invention seeks to solve]

This invention was made in order to solve one of the technical problems related to the shape of articles mentioned above, namely the problem of cleaning articles in the shape of a long rectangular pipe. [Means for Solving Problems] A method for cleaning the entire inner surface of a long rectangular pipe at one time and its equipment are provided. As a result of careful consideration of the shape, material type, quantity, etc., the equipment was designed to be equipped with a cleaning tank and a pump when required.

Combining a flexible pipe and a multi-tube type tank, the cleaning liquid is pumped inside the long square pipe and cleaned while being circulated for the required time, followed by air 7 lashing.

Flushing with water? It is characterized by repeatedly discharging the cleaning liquid remaining inside the pipe.

The invention will be explained in more detail below.

The method and apparatus for cleaning a long rectangular pipe-like article of the present invention includes first arranging a plurality of second pipes having relatively small diameters at a predetermined interval in a first pipe having a predetermined diameter. , fix both ends of the second pipe to the partition plate, and then insert the long square pipe into the second pipe.

The first and second pipes and partition plates are preferably made of plastic to prevent them from being eroded by the cleaning liquid. Also, the diameter of the second pipe is similar to that of a long square pipe.
It is best to use the same diameter as the long square pipe.

The method and apparatus for cleaning long rectangular pipe-shaped articles of the present invention include a storage tank for cleaning liquid, a pedestal to which a pump is attached, a multi-tubular tank for completely cleaning the long rectangular pipe, and a system for completely forming the flow path. When necessary, a storage tank, a pump, and a multi-tube tank are arranged at appropriate intervals, and each is connected by a flexible pipe to form one line. Next, operate the pump to circulate the cleaning liquid and clean the inside of the long square pipe. After cleaning for the required time, use air to drive out the cleaning liquid remaining in the long square pipe (7 lashes of air).
First, water is pumped to clean the inside of the long square pipe (flushing with water).

After the cleaning in the first step, the cleaning liquid in the second step is pumped and circulated inside the long rectangular pipe, and air 7 lashing and water flushing are performed. This washing process is repeated from time to time.

Therefore, in order to facilitate the supply of cleaning fluid, air, and water between each process, cleaning fluid storage tanks and pumps are required.

One-touch joints are attached to the multi-tube tank and the flexible pipes that form the flow path.

Also, if such equipment is not required, a storage tank and a pump.

It can be stored in units of multi-tube tanks and flexible pipe stands.

[Effect]

In this invention, the cleaning device is a storage tank and a pump.

Since it is unitized into a multi-tubular tank and a flexible tube, it is possible to arrange all the devices to form a single-line configuration only when necessary.

In addition, storage tanks, pumps, and multi-tube tanks are provided when unnecessary.

Since each flexible tube stand can be stored individually, space is saved.

Since the structure of the multi-tubular tank can be changed in various ways depending on the shape of the article, it is possible to treat articles of any shape.

〔Effect of the invention〕

As explained above, according to the present invention, the cleaning tank can be changed depending on the shape of the article.

Space can be saved because the tanks can be arranged and operated only when necessary, and can be stored separately for each unit when unnecessary.

Therefore, it is most suitable for a high-mix, low-volume live burial system, and the quality of cleaning of articles is stable.
