。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pass-through device in a chemical treatment device, and more particularly to a filtration device in a chemical conversion coating treatment device that effectively captures and removes fine particles without clogging.

For example, in the phosphate treatment of metals, a large amount of spray is generated during this reaction process, and the amount of fine particles is particularly large.

く白濁する不具合があった。However, in recent years, the dipping method (dip method) has come to be widely adopted because it is necessary to perform chemical conversion treatment on the inside of structures that cannot be treated by this spray method. As a result, there have been many problems caused by spray particles floating in the chemical conversion treatment solution adhering to the surface of the object to be treated. In other words, adhering spray often causes paint defects and significantly impairs its functionality. Therefore, removal of this spray in the immersion method has become a major issue. For this reason, various proposals have been made.
Generally, this is removed by collecting or filtering it. As an example, JP-A-57-1269
In the method described in Publication No. 76, the bottom of the chemical conversion reaction tank is improved to prevent the spray once deposited from rising up and to effectively remove it, achieving great results. Methods for depositing and removing such spray are not possible until the floating spray generated in the chemical conversion reaction is removed; therefore,
The spray was not completely removed, and the chemical conversion treatment solution had the problem of becoming slightly cloudy due to the spray.
そこで本発明は、この従来の不具合を解消するために創

細物を完全に除去することを目的とするものである。Therefore, the present invention was created in order to solve this conventional problem.The present invention was created in order to solve this conventional problem. By providing a filtration device for chemical processing equipment, which is characterized in that the chemical treatment liquid is always made clear by trapping the substances with a fibrous p-material provided in the middle of the circulation circuit, The purpose is to perform the treatment as uniformly and well as possible and to completely remove fine particles generated by the chemical treatment or brought in by adhering to the object to be treated.
以下、本発明の特徴を詳述するが、化学処理液例えば、
りん酸塩処理液中に副生ずるスプレ除去操作の基本は、
当然のことながら、スプレの濾過・捕捉であり、この操
作の能率向上が、化成処理の品質向上に直結する。The features of the present invention will be described in detail below.
The basics of the spray removal operation that occurs as a by-product in the phosphate treatment solution are as follows:
Naturally, this involves filtering and capturing the spray, and improving the efficiency of this operation is directly linked to improving the quality of chemical conversion treatment.
一方、スプレ除去用の濾過操作のネックはｐ材の目づま

板１を間隔をおいて多重にした濾過装置のカートリッジ
２を一様流れでない状態の液循環回路の途中に置いた場
合、多孔板１が目づまりを生じ、圧力を犬にしなければ
液の流れが困難で益々目づまり現象が生じる。On the other hand, the bottleneck in the filtration operation for spray removal is clogging of the p-material, and as the clogging increases, the load increases, further reducing the p-filtration efficiency. This is shown in FIG. 2 (LL). If a cartridge 2 of a filtration device in which a large number of perforated plates 1 are stacked at intervals is placed in the middle of a liquid circulation circuit where the flow is not uniform, the perforated plates 1 will become clogged and the liquid will not flow unless the pressure is maintained. Flow is difficult and clogging phenomenon occurs more and more.

相違することが判明した。ここで、一様流れというのは
、以下説明する実施例に示すごとく、液面のすべてを大
気に開放し、同一水平面を維持する条件下で液を流す流
れのことを指す。Therefore, as a result of research on the occurrence of this clogging, the inventors of the present invention determined that the liquid should be transferred in a uniform flow Qbnifornbf.
It was discovered that if the setting was set to low, no clogging occurred. It was found that clogging was significantly different between uniform flow and non-uniform flow. Here, the term "uniform flow" refers to a flow in which the entire liquid surface is exposed to the atmosphere and the liquid flows under conditions in which the same horizontal surface is maintained, as shown in the examples described below.
本発明方法・装置ではｐ材は、多孔性のできるだけ大き
いものの方が好都合であり、例えばガラスウールをゆる
やかにおくことでよい。この炉材の場合、処理液の循環
の抵抗もきわめて少ない。In the method and apparatus of the present invention, it is advantageous for the p-material to be as porous as possible; for example, glass wool may be placed loosely. In the case of this furnace material, the resistance to circulation of the processing liquid is also extremely low.
この理由は、スプレが、第２図（ｂ）で示すように、繊

て長寿命となって運転コストの低減をはかることができ
る。The reason for this is that, as shown in Figure 2 (b), the spray adheres to the surface of the fibrous p-material B in areas that do not impede the circulation of the liquid, and if this is expanded, the flow of the liquid will be affected. It is deposited within the boundary layer, and the flow of the liquid itself is not obstructed, meaning no clogging phenomenon occurs. Therefore, by replacing the p-material, the service life will be extremely long and operating costs can be reduced.
一方、濾過に対して好都合な一様流れによる処理液は、
被処理物を処理する上でも都合がａ ’Ｊ）。On the other hand, processing liquid with uniform flow, which is convenient for filtration,
It is also convenient for processing the object to be processed a'J).
流れのムラがないだけ均一性を保持し、その処理が理想
に近づくのは明白である。It is obvious that uniformity is maintained as long as there is no unevenness in the flow, and the processing approaches the ideal.
本発明方法が、微細物の除去に効果があるほか、液に溶

、この吸着剤が第２図（ｈ）に示すごとく捕捉され、こ
れが精製作用を発揮することによりきわめて効果的に吸
着される大きな特長を示す。The method of the present invention is effective in removing fine particles, and the contaminants dissolved in the liquid are captured by adding fine adsorbents as shown in Figure 2 (h). It has the great feature of being extremely effective in adsorption by exerting purification effects.
更に、処理液の循環の駆動力はごくわずかでよいので、
例えば大気を曝気して生しる噴流の利用で十分目的を達
成できる。Furthermore, since only a small amount of driving force is needed to circulate the processing liquid,
For example, the purpose can be achieved by using jets generated by aerating the atmosphere.
なお、りん酸塩処理に際しては、化成処理液中の酸化剤
濃度が重要であり、硝酸塩・亜硝酸塩過塩素酸塩の添加

この管理はきわめて微妙な高度の技術を必要としていた
が、大気を曝気したことで、大気の酸素供給が一定化さ
れることにより、こうした酸化剤の添加はきわめて小量
でもよくその組成も簡明になり、管理をきわめて容易に
行うことができる特長も得られた。In addition, during phosphate treatment, the concentration of oxidizing agent in the chemical conversion treatment solution is important, and it is necessary to add nitrates, nitrites, and perchlorates, and this addition is deeply involved in the chemical conversion reaction.
This management required extremely delicate and advanced technology, but by aerating the atmosphere, the oxygen supply in the atmosphere was stabilized, so the addition of such oxidizing agents could be done in extremely small amounts and the composition could be simplified. It also has the advantage of being extremely easy to manage.

れている。FIG. 1 shows an embodiment of the present invention, and shows a cross section of a chemical conversion treatment tank 4 in which a dipping method for forming a phosphate film, which is a type of chemical conversion treatment, is carried out. Before and after the chemical conversion treatment tank 4, a surface cleaning tank, a post-treatment tank, etc. (not shown) are arranged in parallel.

ている。The chemical conversion treatment tank 4 is formed in a rectangular shape with the upper side open to the atmosphere, and an inner tank 6 is further arranged inside the acid tank 4 with circulation passages 7 at the front, rear, and bottom sides. The inner tank 6 is provided with a partition plate 5 that can be moved up and down, and by means of the partition plate 5, the inner tank 6 is equipped with a dipping tank 9 for dipping a car body 8, which is a local product, and a cartridge 2 containing a p-material 3. It is divided into an overflow tank 10.

。The partition plate 5 is usually fixed at a position forming the passage 11. 12 is a stirrer used in the immersion tank 9 and is driven by a motor M. 16 is a downward agitator provided upstream of the circulation path 7, and is driven by a motor M. A heater 14 is inserted downstream of the circulation path 7 to control the temperature of the liquid and at the same time form an upward flow caused by the heating. Heater 14
A pipe 15 for performing atmospheric aeration is inserted in parallel to the pipe.

拌機１６を駆動すればよい。In this example having the above-described configuration, first, a cloudy, cloudy chemical conversion treatment liquid that had been used in another chemical conversion treatment tank was passed through. When the temperature control scale was set at 50°C and the treatment liquid was aerated with the atmosphere at 50z/min, the circulation rate was 100°/min. The circulation flow rate is determined by the resistance of the circulation circuit, so if it is desired to increase the flow rate, the cross-sectional area of the circulation path 7 may be increased. When it is not desired to aerate the chemical conversion treatment liquid with the atmosphere, the downward agitator 16 may be driven.
カートリッジ２の底は網目の粗いものにし、ガラスウー
ルを軽くつめておく。このガラスウールによって槽９と
１０の液面が数ｍｍの液面差しか生じなく、このＰ材の
抵抗が小さいことがわかった。The bottom of cartridge 2 should have a coarse mesh and be lightly stuffed with glass wool. This glass wool caused a difference in the liquid levels between tanks 9 and 10 by only a few mm, and it was found that the resistance of this P material was small.

Even the cloudy chemical conversion treatment liquid became transparent, and slag accumulated in the cartridge 2. At this time, there was almost no increase in the liquid level difference (count □□) and the circulation flow rate did not change.

便利であることも効果である。すなわち、多量に発生す
るこのスラグの廃却に際し、従来、問題が多かったが、
簡単に固形化できたことで再利用の道を開くこともでき
る。If you look closely at the glass wool inside the cartridge 2, you will see that the slag adheres to the surface of the glass wool and is deposited in the boundary layer of the flow, and the flowability of the liquid passing through the glass wool is not impaired in the slightest. Therefore, if the cartridge 2 is slowly pulled up from the processing liquid, immersed in a separate tank and vibrated, the slag will float again and glass wool can be used. Another advantage is that sintering together with glass wool makes it convenient to dispose of slag. In other words, there have been many problems in the past when disposing of this slag, which is generated in large quantities.
The fact that it can be easily solidified opens the door to reuse.

良好な化成処理ができた。Next, in this example, the car body 8 was immersed in the chemical conversion treatment liquid that had been regenerated to be transparent to perform the chemical conversion treatment. Since the degree of stirring of the acid solution was small, the stirrer 12 was driven to capture it. The circulation of the formed metal body was maintained regardless of this stirring action. Even when the chemical conversion treatment was carried out continuously, the chemical conversion treatment liquid did not become cloudy at all, and all the generated slag was collected in the tank. With this equipment, slag can be removed at the same time as chemical conversion treatment, so slag does not float, there is no slag attached to the chemical conversion treatment film, and the liquid flow is uniform, allowing for uniform and dense treatment. Together, we were able to achieve extremely good chemical conversion treatment.
更に、本化成処理槽４で使用する化成処理液劣化防止に
ついて述べる。Furthermore, prevention of deterioration of the chemical conversion treatment liquid used in the present chemical conversion treatment tank 4 will be described.

発生して初めて再生処理をせざるを得なかった。As is well known, if chemical conversion treatment is carried out continuously, the finish may be poor even though the composition of the straw material is kept the same.In this case, adsorbents such as activated carbon may be added. It has been confirmed that it can be played. As shown in FIG. 6, it is difficult to decide when to perform this process, and countermeasures are desired to prevent the current situation in which many defective products are produced and then recycled. In addition, thick arrow A indicates regeneration♂ In other words, if a degraded chemical conversion solution can be regenerated by treatment with an adsorbent such as activated carbon, it is clear that deterioration can be prevented by constantly performing this adsorption treatment. However, since no equipment was known to carry out this process, recycling had to be carried out only after deterioration and defective products occurred.

。However, with this chemical conversion treatment tank 4, even if the adsorbent (ion exchange resin or activated carbon) 17 is installed all the time, it will not interfere with the original chemical conversion reaction operation, and even if it is constantly operated, the cost is low. , was carried out for the first time. This will be explained below.

とがわかる。In FIG. 1, before installing the chemical conversion treatment tank 4 and the cartridge 2, a gauze cloth bag 16 wrapped with commercially available activated carbon is installed. A car with glass wool placed upstream of it) I
J Tsuji 2 was installed. No change in circulation rate could be detected. The difference in liquid level between the dipping tank 9 and the p-filtration tank 10 is 3 degrees. It is a very small amount and can be regarded as a horizontal plane. In other words, it can be seen that the adsorbent and glass wool do not act as a resistance to circulation.

に示す。At first, the fine powder in the activated carbon flowed out and the chemical conversion solution became black and cloudy, or when the electricity was restored for about 10 minutes, the activated carbon adhered to the glass wool and became clear. Therefore, the activated carbon does not need to be placed in a special gauze cloth bag as described above. This is only to prevent a large amount of activated carbon from being mixed into the slag. After that, zinc phosphate film treatment was performed continuously using a commercially available zinc phosphate treatment agent (Granozin manufactured by Nippon Peso), and the results of this and the conventional method in a circular beaker are shown in Table 1.
Shown below.

理を損っていた。Next, the apparatus of the present invention was employed in an alkaline liquid degreasing process for this phosphate treatment agent. Dust adheres to the object to be treated, and in the conventional method, it floats in the alkaline treatment solution, and uneven degreasing often occurs due to uneven flow, impairing the chemical conversion treatment.

流れに要する動力も少なくてすむ。■Since the chemical treatment liquid is circulated in a uniform flow and the object to be treated is immersed in the liquid, the chemical treatment is performed uniformly over the entire object, improving treatment quality and increasing the flow of the liquid. It also requires less power.
■−一様流の循環回路の途中に繊維状部材を設けだので
、全量確実に該部材を通過させるにもかかまりが生じな
い。- Since a fibrous member is provided in the middle of the uniform flow circulation circuit, the entire flow can be passed through the member without any obstruction.
■化学処理により発生した微細物は、直ちにＰ拐により
捕捉するので、該微細物によって化学処理が影響される
ことがない。(2) Fine particles generated by chemical treatment are immediately captured by P-filtering, so that chemical treatment is not affected by the fine particles.
０戸材が繊維状であるので、網目が多数形成されうるに
もかかわらず、目づまりが生じないことから、液の白濁
