Abstract

Foreign matter contained in cooling water is adsorbed and accommodated and easily and efficiently removed.
The apparatus is connected to an appropriate position of a cooling water circulation passage pipe with a hose to purify the cooling water. First, turbid cooling water flows from the cock A, light oil or the like floats upward, and heavy metallic fine particles sink downward and are attracted and accumulated by the magnetic force. The cooling water that has passed through the filter element 13 is purified and passes through the discharge pipe hole, and the purified cooling water from the discharge cock B returns to the circulation flow path. To replace the cartridge filter, first, the cocks A and B are closed, and the residual pressure is extracted and taken out by the drain plug 14, so that a safe operation can be performed in a short time without leakage of cooling water.

Description

Industrial application fields

The present invention relates to a device for purifying cooling water of a water-cooled engine.

Most engines mounted on vehicles are water-cooled engines, and coolant is circulated to cool the engines. Conventionally, this coolant has to be replaced periodically or purified and regenerated after the engine has been operating for a long time. For this reason, several purification devices have been developed. However, these purification devices have not been put into practical use because of the drawbacks that it takes time to replace and clean the filter.

The problem the device is trying to solve

However, maintenance of cooling water has not been emphasized so much and has not been carried out for many years, and it is generally used for a long period of time. The cooling water contains fine particles such as rust and a small amount of engine oil due to gasket deterioration Mixes and becomes cloudy brown. The dissolved matter such as rust may cause failure of various parts of the engine, such as cooling effect deterioration due to clogging and adhesion of the cooling circulation part, leakage due to corrosion, abnormal noise due to wear inside the water pump, and leakage. On the other hand, when LLC used for cooling water is composed mainly of harmful ethylene glycol, it causes environmental problems such as water pollution.

An object of the present invention, as a method for solving the above-described problem, is to purify and regenerate the cooling water by removing the foreign matter by attaching the present device to an appropriate position of the cooling water circulation passage.

Means for solving the problem

In order to achieve the above object, the cooling water is purified and regenerated by forming a diversion channel directly at an appropriate position of the cooling circulation channel and connecting it to the apparatus with a connection hose.
In addition, foreign substances in the cooling circulation system float and circulate most frequently during high temperature and high rotation water flow.

Therefore, since the purification under the above conditions can be performed most efficiently, this device is installed, and a part of cooling circulating water at the time of engine operation is circulated to this device with a connecting hose, and the cooling water is always purified. It was adopted.

Action

According to the present invention, the cooling water is always kept free of turbidity by adsorbing and collecting dissolved foreign substances contained in the cooling water by the above-described configuration.

An embodiment in which the device of the present invention is mounted on a large vehicle will be described with reference to the drawings.
FIG. 1 is an example of a configuration diagram of a general cooling circulation system, and a water hose 5 constantly circulates cooling water from a thermostat case 4 to a sub tank 3.
Therefore, the present apparatus shown in FIG. 3 is attached to the flow path of the water hose 5 shown in FIG. 2, but it may be attached to the heater hose 6 or the like by forming a diversion flow.

The cartridge filter case 11 is screwed into the filter mounting bolt 8 and the filter gasket 15 is brought into close contact therewith.
The drain plug 14 is used for removing residual pressure and air when replacing the filter, and discharging the accumulated oil.

A permanent magnet 12 was attached to the outer bottom of the cartridge filter case 11. As a cartridge filter for filtering and adsorbing the foreign matter, a commonly used fuel filter for a diesel engine is employed. These are integrated into a filter body mount 9 by tightening them with bolts.

サブタンク３も接続。エンジンのサーモスタットケース４から、コックＡに流入した、濁った冷却水は、フィルタボデーの通路を通りフィルタケース外室に入る、そこでオイルなどの軽いものは上へ浮き、重い金属性微粒物質などは下へ沈み永久磁石１２の磁力により吸着され堆積していく。さらに、フィルタエレメント１３にて濾過吸着され浄化された冷却水は内室に入る、浄化された冷

へ戻される。またフィルタに吸着された異物は、比重が重くエンジン停止中数時間で下へ沈む性質があり、フィルタの目詰まりが起こり難く、長期間のフィルタ交換を必要としない。Next, the function will be described.

Sub tank 3 is also connected. The turbid cooling water flowing into the cock A from the thermostat case 4 of the engine passes through the passage of the filter body and enters the outer case of the filter case, where light things such as oil float up, heavy metal particulate matter etc. It sinks down and is attracted and deposited by the magnetic force of the permanent magnet 12. Furthermore, the cooling water filtered and adsorbed by the filter element 13 enters the inner chamber, and the purified cooling water.

Returned to In addition, the foreign matter adsorbed on the filter has a characteristic that it has a high specific gravity and sinks down within a few hours while the engine is stopped, the filter is not easily clogged, and does not require long-term filter replacement.

冷却水を遮断し、ドレンプラグ１４を緩めて残圧を抜き、フィルタを取り出すことで漏洩を極力防ぎ、フィルタ脱着が冷却水高温時にも、容易に行うことができる。On the other hand, the oil C that floats and accumulates, and whose specific gravity is light and does not sink, is not returned to the sub tank 3 because the discharge port of the discharge pipe 10 is at the lower part. The drain plug 14 is used for discharging a large amount of oil and for releasing pressure and air when the cartridge filter is replaced. By loosening the drain plug 14, the drain plug 14 is discharged from the drain pipe. When the cooling water is hot, water pressure is generated by the action of the radiator cap, which is dangerous.

The cooling water is shut off, the drain plug 14 is loosened to release the residual pressure, and the filter is taken out to prevent leakage as much as possible. The filter can be easily detached even when the cooling water is hot.

effect

As a result of installing the device of the present invention on a large vehicle, the brown turbidity disappeared in a few days, and an excellent effect that a large amount of foreign matters can be purified and removed was found. Cooling water that has become turbid due to rust cannot be completely removed by washing or replacement, and turbidity due to foreign matter is generated again. This can be solved by installing this device and replacing the filter if necessary.

In addition to purification, the device can be installed efficiently and safely in a short time, and it is economical without discarding cooling water. It is something that demonstrates.
