Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoop material cleaning apparatus for degreasing and cleaning the surface of a long and thin plate-shaped hoop material.

[0002]

2. Description of the Related Art Conventionally, as a method for cleaning the surface of a long member, for example, a shaped steel, a cleaning step of completely immersing the long member in a cleaning liquid tank in which a cleaning liquid such as an organic solvent is stored. The method of separately carrying out the drying step of drying the long member taken out from the cleaning liquid tank has been adopted.
In this case, since the cleaning process and the drying process can be carried out in a space isolated from the outside, respectively, it is possible to effectively prevent scattering of the cleaning liquid and mixing of dust from the outside.

[0003]

However, in the case of degreasing / cleaning a hoop material formed to be longer than a long member such as a shape steel, for example, a rolled steel material wound in a coil shape, It is unrealistic to provide a cleaning liquid tank or the like for completely immersing the tank in consideration of its installation area and the like.
Also, when the cleaning liquid tank or drying chamber is inserted while feeding the hoop material to degrease and clean the surface, the entire hoop material cannot be placed in the cleaning liquid tank or drying chamber, so It is conceivable that dust may be mixed in from the boundary portion between or and the cleaning liquid or the like may leak to the outside.

Further, when an organic solvent is used as the cleaning liquid, it is necessary to adopt a completely airtight structure due to its high volatility. However, as described above, the hoop material is fed and the cleaning chamber or the like is inserted therethrough. Therefore, it is difficult to achieve a completely airtight structure. On the other hand, when a water-soluble cleaning liquid is used, it is considered that the cleaning liquid is used at a high temperature in order to improve the cleaning power. In this case, the cleaning liquid is evaporated in the cleaning chamber or the drying chamber. There is a problem of vapor condensation due to.

In other words, dew drops of vapor may fall onto the hoop material and be carried out of the cleaning chamber. If the dew drops are put into the drying chamber with the dew drops attached, stains of the dew drops on the hoop material may occur. Will be formed. Furthermore, when dew drops adhere to the hoop material carried out from the drying chamber, the hydrogen atmosphere in the bright annealing furnace arranged in the subsequent stage may be destroyed.

The present invention has been made in view of the above circumstances, and is capable of reliably degreasing and cleaning the hoop material and continuously producing a hoop material having a clean surface state free from dust and stains. An object is to provide a hoop material cleaning device that can be carried out.

[0007]

In order to achieve the above object, the present invention allows a hoop material fed in one direction to be inserted into a tunnel-shaped processing chamber which is partitioned from the outside, and the hoop material is inserted into the processing chamber. A cleaning device for continuously degreasing and drying the space between the cleaning chamber and a cleaning unit for injecting the cleaning liquid into the hoop material, and a cleaning liquid disposed on the subsequent stage of the cleaning unit to clean the cleaning liquid attached to the hoop material. A rinse part to be washed away by the cleaning part and a drying part, which is arranged at a subsequent stage of the rinse part and which dries the cleaning liquid adhering to the hoop material, are provided, and a space is provided on the front and back sides of the hoop material before and after the cleaning part and the rinse part. We proposed a hoop material cleaning device that is provided with a nozzle that blows pressurized air diagonally to the front and back surfaces of the hoop material in the longitudinal direction toward the inside of the hoop material cleaning section or the rinse section. There.

In the above hoop material cleaning apparatus, if a suction means for sucking the processing chamber to a negative pressure is connected to the processing chamber, the vapor generated in the processing chamber is scattered and the cleaning liquid and the cleaning liquid are scattered. Is effective in that it is prevented.

Further, in the above hoop material cleaning device,
The suction means is composed of a flow passage formed above the processing chamber by a partition plate arranged above the hoop material and partitioning the processing chamber into upper and lower parts, and a suction blower connected to the flow passage. With the configuration in which a plurality of through-holes that penetrate vertically are provided, it is possible to effectively prevent the vapor from being dissipated and also to prevent dew drops from falling onto the hoop material.

Further, in the above-mentioned hoop material cleaning apparatus, the drying section is provided with a drying nozzle for blowing heated air to the front and back surfaces of the hoop material, and the drying nozzle provided near the outlet of the processing chamber is the outlet. Generating an air flow in the direction is effective in preventing dust from adhering to the hoop material.

[0011]

According to the hoop material cleaning apparatus of the present invention, the hoop material fed in one direction and inserted into the tunnel-shaped processing chamber is first degreased by being sprayed with the cleaning liquid in the cleaning section. Next, in the rinse portion, the cleaning liquid adhering to the hoop material is washed away by the cleaning liquid. Then, after that, the cleaning liquid is dried in the drying unit, whereby the degreasing and cleaning of the hoop material is completed.

In this case, in the cleaning unit, pressurized air is ejected from nozzles arranged before and after the cleaning unit. The pressurized air ejected from the nozzle is blown diagonally to the front and back surfaces of the hoop material in the longitudinal direction toward the inside of the cleaning part, so the cleaning liquid sprayed on the hoop material in the cleaning part is cleaned along the hoop material. It is prevented from flowing out of the part.

Therefore, it is possible to prevent the cleaning liquid from leaking to the outside from the inlet of the processing chamber, and also to prevent a large amount of the cleaning liquid from being supplied to the rinse section arranged in the subsequent stage of the cleaning section. As a result, it is possible to suppress changes in the concentration of the cleaning liquid in the cleaning unit and changes in the cleanliness of the cleaning liquid in the rinse unit.

Further, in the cleaning section, the cleaning liquid is urged so as to remain on the front and back surfaces of the hoop material, so that the hoop material is arranged as if it was immersed in the cleaning liquid, and the cleaning effect is obtained. Will be raised. Also,
Since the cleaning liquid is urged by the pressurized air, it is possible to keep the surface of the hoop material passed from the cleaning unit to the rinse unit so as not to be completely dried. This prevents the dried cleaning liquid from sticking to the surface of the hoop material and forming a stain.

Also in the rinsing section, the pressurized liquid is jetted inward from the rinsing section from the nozzles arranged before and after the rinsing section, so that the cleaning liquid jetted in the rinsing section can be washed in the preceding washing section and the latter stage. Flow to the drying section is avoided. As a result, the concentration of the cleaning liquid is prevented from decreasing, and the cleaning liquid that is urged to stay on the front and back surfaces of the hoop material ensures that a small amount of cleaning liquid is attached to the front and back surfaces of the hoop material without sticking. It becomes possible to wash it away.

After that, the hoop material from which the cleaning liquid has been completely washed off is sent to the drying section to evaporate the cleaning liquid. As a result, it is surely degreased,
The dried hoop material from which dust and cleaning liquid have been completely removed is delivered from the processing chamber outlet. That is, while feeding in one direction, the surface is continuously degreased and washed,
A hoop material in a dried state will be obtained.

If the hoop material cleaning device is provided with suction means for sucking the processing chamber to a negative pressure,
It is possible to more effectively prevent the cleaning liquid and the cleaning liquid from leaking from the processing chamber. That is, it is possible to prevent the spray of the cleaning liquid and the cleaning liquid, and the vapor of the cleaning liquid and the cleaning liquid in the high temperature state from leaking to the outside from the inlet / outlet of the processing chamber.

Therefore, it is possible to prevent the occurrence of dew condensation in the structure arranged near the entrance and exit, maintain the soundness of the structure, and prevent the concentration change of the cleaning liquid or the like.

Further, the suction means comprises a flow passage formed above the processing chamber by a partition plate which is arranged above the hoop material and divides the processing chamber into upper and lower parts, and a suction blower connected thereto. If the partition plate is provided with a plurality of through-holes penetrating up and down, the suction chamber blows the negative pressure into the processing chamber through the flow passage and the through-holes. In this case, the flow cross-sectional area of the flow passage can be made sufficiently smaller than that of the processing chamber, and this makes it possible to apply suction by the suction blower to the entire processing chamber. Further, by providing the through hole at a desired position, it becomes possible to increase or decrease the suction force at each position of the processing chamber.

Moreover, by providing the partition plate having the through hole in the upper part of the processing chamber arranged above the hoop material, the mist and vapor of the cleaning liquid generated in the processing chamber is sucked upward through the through hole. At this time, a part of the steam or the like is condensed on the partition plate, but the sudden flow of air flowing upward through the through hole prevents its fall. Therefore, it is possible to prevent the dew drop from falling on the hoop material, and to avoid inconveniences such as generation of stains on the surface of the hoop material and reduction of hydrogen concentration in the annealing furnace arranged in the subsequent stage.

Further, if a drying nozzle for blowing heated air to the front and back surfaces of the hoop material is provided in the drying section to generate an air flow in the outlet direction in the drying nozzle arranged in the vicinity of the outlet of the processing chamber, suction is performed. Even when the processing chamber is in a negative pressure state due to the operation of the means, it is possible to avoid suction of external dust or the like from the outlet of the processing chamber to the drying section due to the air flow due to the operation of the drying nozzle. As a result, the cleanliness inside the drying section is maintained, and dust is prevented from adhering to the surface of the hoop material during the drying process.

For example, as shown in FIGS. 3 and 4, the flow passage 28 is partitioned and formed by a horizontal partition plate 30 arranged so as to partition the entire processing chamber 2 into upper and lower parts, and is sufficiently larger than the cross-sectional area of the processing chamber 2. It has a small flow cross section. The partition plate 30 is a flat plate having a plurality of through holes 30a, such as punching metal.

The through holes 30a may be provided so as to be uniformly distributed over the entire area of the processing chamber 2, or the nozzles 24a, 24b, 25a, 25b of the cleaning section 15 and the rinse section 16 may be provided.
In order to improve the suction effect of the suction blower 29, the number of the through holes 30a may be reduced in the portion arranged above.

The operation of the hoop material cleaning apparatus 1 of the present embodiment thus constructed will be described below. The hoop material 18 fed from an uncoiler (not shown) is temporarily supported by a receiving roller 19 and inserted into the processing chamber 2 through an inlet 13 of the processing chamber 2, and is fed in one direction while being guided by a supporting roller 20 and a guide roller 21. To be The hoop material 18 that has entered the processing chamber 2 is first cleaned in the cleaning unit 15.

In the cleaning section 15, the cleaning liquid S is sprayed on the front and back surfaces of the hoop material 18 by the operation of the cleaning liquid spraying means 22, and the oil and fat adhering to the surface of the hoop material 18 is degreased and cleaned. In this case, in the cleaning unit 15, the cleaning liquid W is sprayed at a high pressure and is heated to a high temperature state of 60 to 70 ° C., so that the spray and the steam V are filled.

The atomized powder such as the steam V is sucked from above by the suction means 3. Also, the cleaning unit 1
5 by the air curtain formed by the nozzles 24a and 24b arranged before and after 5,
Leakage to the outside of the cleaning unit 15 from the through hole 27a to the rinse unit 16 is avoided.

The cleaning liquid S sprayed on the front and back surfaces of the hoop material 18 is urged inwardly of the cleaning unit 15 by the air flow A formed by the nozzles 24a and 24b arranged before and after the cleaning unit 15. . That is, the cleaning liquid S disposed on the front and back surfaces of the hoop material 18 tries to flow through the hoop material 18, but the air flow A formed by the nozzles 24a and 24b functions like a scraper and functions as a hoop material. Scraped from 18. In this case, unlike the mechanical scraper, the front and back surfaces of the hoop material 18 are not rubbed and scratches are not generated.

Moreover, the cleaning liquid S, which is blocked by the airflow A of the nozzles 24a and 24b from flowing outward on the hoop material 18, is urged to concentrate near the center of the cleaning portion 15. Therefore, in that portion, the hoop material 15 is in a state as if it was immersed in the cleaning liquid tank, so that the cleaning effect is enhanced.

Further, the nozzle 24b arranged at the rearmost part of the cleaning unit 15 does not dry the cleaning liquid S adhering to the front and back surfaces of the hoop material 18, but leaves the cleaning liquid S thinly adhering to the front and back surfaces. You can Therefore, it is possible to prevent the front and back surfaces of the hoop material 18 delivered from the cleaning unit 15 from being dried before being put into the rinse unit 16, and the cleaning liquid S may adhere to the front and back surfaces to form a stain. Can be prevented. Moreover, the carry-in of the cleaning liquid S into the rinse section 16 can be suppressed to a minimum, and the contamination of the pure water in the rinse section 16 can be suppressed to a minimum.

Next, the hoop material 18 delivered from the cleaning unit 15 is put into the rinse unit 16 with a small amount of the cleaning liquid S attached to the front and back surfaces as described above. Rinse section 16
Then, the pure water W is sprayed on the front and back surfaces of the hoop material 18 by the operation of the cleaning liquid spraying means 23, and the cleaning liquid S adhering to the front and back surfaces is completely washed away. Also in the rinse section 16, as in the cleaning section 15, the nozzle 25
By the air flow A generated by a · 25b and the suction means 3, it is possible to prevent the vapor V of the pure water W and the spray from leaking to the cleaning unit 15 and the drying unit 17. In addition, a large amount of pure water W that scrapes the front and back surfaces of the hoop material 18 into the center of the rinse portion 16 by the air flow A of the nozzles 25a and 25b.
Thus, the cleaning liquid S can be efficiently washed out.

Further, the hoop material 18 from which the cleaning liquid S has been completely washed off in the rinse section 16 is sent out from the rinse section 16 with a small amount of pure water W attached to the front and back surfaces, and is introduced into the drying section 17. It In the drying section 17, the hot air B from the hot air jetting means 26 is blown to the front and back surfaces of the hoop material 18, so that a small amount of pure water W is immediately dried. Then, the hoop material 18 that has been degreased and washed in this way is delivered from the outlet 14 of the processing chamber 2 in a dried state.

Since each operation in the cleaning section 15, rinsing section 16 and drying section 17 as described above is continuously performed on the hoop material 18 fed in one direction, degreasing and
The washed hoop material 18 can be continuously obtained.
Moreover, since the hoop material 18 is partially processed while the hoop material 18 is inserted through the tunnel-shaped processing chamber 2, it is not necessary to install a cleaning liquid tank or the like for immersing the entire hoop material 18, The installation space can be reduced.

Further, in the hoop material cleaning apparatus 1 of this embodiment, since the entire processing chamber 2 is sucked to a negative pressure, the cleaning liquid S
It is possible to prevent the steam V of pure water W from leaking to the outside of the processing chamber 2. As a result, it is possible to prevent the mechanical portion such as the receiving roller 19 arranged outside the processing chamber 2 from being damaged by corrosion due to dew condensation.

On the other hand, the operation of the suction means 3 causes the outside air containing dust to flow from the inlet / outlet ports 13 and 14 of the processing chamber 2 to the processing chamber 2.
However, in this embodiment, the hot air jetting means 26 arranged near the outlet 14 of the processing chamber 2
Since the airflow outward from the outlet 14 of the processing chamber 2 is generated, suction of dust from at least the outlet 14 of the processing chamber 2 is avoided. Therefore, it is possible to effectively prevent dust from adhering to the front and back surfaces of the hoop material 18 in the semi-dried state or the undried state disposed in the drying section 17 and being fixed by drying.

Further, in the hoop material cleaning apparatus 1 of this embodiment, the suction means 3 is provided in the upper part of the processing chamber 2, and the partition plate 30 having the through hole 30a is used to form the flow passage 28 over the entire length of the processing chamber 2.
Therefore, the suction force of the suction blower 29 can be effectively applied to the entire processing chamber 2. Further, at the same time, even when the vapor V of the cleaning liquid S or pure water W adheres to and is condensed on the ceiling surface of the processing chamber 2 constituted by the partition plate 30, it is formed on the ceiling surface. Through hole 30a
Since a high-speed airflow is generated toward the upper flow passage 28, the dew drops from the ceiling surface are effectively prevented from falling onto the hoop material 18.

Therefore, it is possible to prevent the surface condition of the degreased / washed / dried hoop material 18 from being contaminated by dew droplets. It is possible to avoid the occurrence of defects such as the destruction of the hydrogen atmosphere caused by the charging into the bright annealing furnace (not shown) arranged in the above.

In this embodiment, the cleaning liquid S is an alkaline cleaning liquid and the cleaning liquid W is pure water. However, the cleaning liquid S and the cleaning liquid W are not limited to these, and any cleaning liquid S and cleaning liquid W may be selected. it can. Processing chamber 2
The shape, the number of cleaning liquid ejecting means 22, the number of cleaning liquid ejecting means 23, and the like are not limited at all.

Further, the angle of the air flow A from the nozzles 24a, 24b, 25a, 25b for scraping off the cleaning liquid S or the like on the hoop material 18 can be adjusted appropriately. Further, the hot air jetted from the hot air nozzle 26b is made to enter the front and back surfaces of the hoop member 18 at a right angle to generate an air flow outward from the outlet 14 of the processing chamber 2.
Instead of this, it is also possible to separately arrange a nozzle that generates only an airflow directed from the processing chamber 2 outlet 14 to the outside.

A rinse part to be washed away with the liquid and a drying part to dry the cleaning liquid are sequentially arranged. Before and after each of the cleaning part and the rinse part, the inside of the cleaning part or the inside of the rinse part is attached to the front and back surfaces of the hoop material. Since a nozzle that blows pressurized air is installed diagonally, the cleaning liquid that flows along the hoop material and that flows out of the cleaning part and the cleaning liquid that flows out of the rinse part are blocked by the pressurized air from the nozzle, and the outside of the processing chamber This has the effect of preventing leakage to other adjacent parts.

In this case, instead of mechanically scraping off the cleaning liquid or the like adhering to the front and back surfaces of the hoop material,
Damage to the front and back of the hoop material is avoided because it is only dammed by pressurized air. further,
The hoop material cleaned in the cleaning part can be advanced to the rinse part without drying the cleaning liquid adhered to the front and back surfaces of the hoop material, so that it is possible to prevent the stain due to the drying of the cleaning liquid from sticking to the hoop material. it can.

If the suction means for sucking the processing chamber to a negative pressure is provided in the hoop material cleaning apparatus, in addition to the above-mentioned effects, the cleaning liquid and cleaning liquid in the form of vapor or mist generated in the processing chamber can be obtained. Is effectively prevented from leaking to the outside of the processing chamber or an adjacent part thereof, thereby preventing the work environment outside the processing chamber from being contaminated and the mechanical portion from being damaged due to dew condensation.

Further, the suction means is composed of a flow passage formed by a partition plate which is arranged above the hoop material and divides the processing chamber into upper and lower parts, and a suction blower connected to the flow passage, and the suction means is arranged above and below the partition plate. In addition to the above effect of preventing the leakage of vapor etc. by sucking the entire processing chamber by providing a plurality of penetrating holes, the dew droplets that condense on the ceiling are sucked upward through the penetrating holes, and the hoop It is possible to prevent the material from falling on the material.
