Description

[Detailed Description of the Invention] The present invention relates to an improvement of a pickling device for descaling a coil wire wound into an east node shape by immersing it in an acid solution.

Conventionally, there is a type of seed pickling equipment as shown in Figure 1. In this figure, 1 is a pickling tank containing an acid solution 2 such as sulfuric acid or hydrochloric acid, and 3 is a pickling tank suspended by an overhead crane. It is a suspension stand that is lowered, transported to the upper part of the pickling tank 1 and suspended over the tank 1, and an L-shaped support arm 4 is attached to the lower surface of the suspension stand.

The cylindrical coil wire 5 is inserted into and supported by the support arm 4 with its inner circumferential center axis in the horizontal direction, and is immersed in the acid solution 2 and vibrated by the vibration motor 6 installed in the pickling tank 1. The scale is removed with the following steps.

However, in the above device, in the arm 4 which is cylindrical and inserts and supports the coiled wire 5 so that the center axis of the wire is horizontal, the vertical base 4 of the arm 4 is connected to the suspension base 3. Although the coil wire material 5 is made to have a strong and large diameter and is exposed in the acid solution 2, there is a loss in that the acid solution 2 existing around the base 4a, especially below, becomes unused.
There was an economic loss in that a large amount of expensive acid was required compared to the size and amount of the stool.

Further, vibration is applied to this device by a vibration vibration motor 6.

However, there is almost no movement around the central axis of the coiled wire 5, and therefore, the lower part of the outer peripheral surface of the wire 5 is used as a casing 1 that is close to and faces the sludge 7 deposited at the bottom of the tank 1, and the acid in that part is This will result in insufficient washing.

The vibrating structure has the disadvantage that the device is easily damaged in a short period of time.

The present invention improves the above-mentioned drawbacks of the conventional method, allows full use of the entire acid solution in the pickling tank, and saves acid solution.
The present invention also aims to provide a coil wire pickling device that can uniformize pickling, shorten pickling time, and improve the durability of the device. In an apparatus for descaling a coiled wire material wound into a shape by immersing it in an acid solution, the suspension table is equipped with a drive motor and is suspended above a pickling tank containing a carbon acid solution;
a vertical shaft protruding downward from the suspension base and rotationally driven by the motor; and a rotation support made of an acid-resistant material that is removably suspended from the lower end of the vertical shaft and rotates around the vertical axis. The rotating support has a flow section that is inserted into the inner periphery of the cylindrical coil wire with the inner periphery center axis in the vertical direction, and that allows the acid solution to freely flow in and out of the cylindrical coil wire. The present invention is comprised of a vertical body and a flange extending outwardly from the lower end of the vertical body and on which the lower end surface of the wire is placed.

Embodiments of the present invention will be described below with reference to FIGS. 2 and 3.

In FIGS. 2 and 3, 10 is a pickling tank similar to the conventional pickling tank 1 shown in FIG. 1, and an acid solution 11 such as sulfuric acid or hydrochloric acid is contained therein.

Reference numeral 12 denotes a suspension frame having a length that can be hung over the top of the pickling tank 10, and a drive motor 13 and a speed reducer 14 are mounted on the suspension frame.

In addition, a vertical shaft 15 is provided on this table 12 and extends vertically through a part of the table 12 and protrudes downward from the lower surface. It is supposed to be done.

16. 17 is a cylindrical coil wire that is wound into a cylindrical shape before being pickled, and 17 is a rotating support that is made of an acid-resistant material, such as a stainless steel rod, and is assembled into a cylindrical shape. Vertical body 1 configured to have a flow section that allows acid solution 11 to freely flow inside and outside the cylinder between the materials.
8, and a flange 19 extending radially outward from the lower end of the body 18.

The seventh end of the vertical body 18 of this rotary support 17 is narrowly narrowed and has a housing-shaped neck 20, and the lower end of the vertical shaft 15 is provided with a locking rod 22 that can be freely raised and tilted around a pin 21. In addition, the locking rod 22 can be releasably hooked onto the neck portion 20.

In order to pickle the cylindrical coil wire 16, first, pickle the inner periphery of the cylindrical coil wire 16 from the vertical axis 15 so that the center axis of the inner periphery of the cylindrical coil wire 16 is in the vertical direction. While inserting the vertical body portion 18 of the rotation support 1/7 that has been removed once,
The lower end surface of the wire 16 is placed on the collar portion 19.

Next, the neck portion 20 of the rotary support 17 is hooked onto the lower end of the vertical shaft 15, and then the suspension base 12 is secured to the rope 23 using a crane or the like.
Or hang it via the hook 24 and attach it to the top of the pickling tank 10.
Then, the suspension stand 12 is suspended over the pickling bath 10 as shown in FIG. 2, and the box-shaped coil wire 16 is entirely immersed in the acid solution 11.

When the drive motor 13 is driven, the rotary support 7 rotates around the vertical axis 15, and the cylindrical coil wire 16 placed thereon also rotates at a slow speed while facing resistance from the acid solution 11. Acid solution 11 flowing inside and outside the rotating support 11
The entire inner and outer peripheries are pickled to remove scale.

After pickling, the suspension frame 12 is lowered from the pickling tank 10 by a crane, and the cylindrical coil wire 16 is lowered by rotating and removing the support 17 from the vertical shaft 15.

In the illustrated example, one suspension stand 12 is provided with two rotational supports 17 so that the coil wires 16 placed on each supporter 1T can be pickled at the same time, but only one supporter 1T is provided, Alternatively, it is optional to provide three or more.

In the illustrated example, a blade 25 is detachably attached to the lower surface of the flange 19 of the rotary support 1T, so that the acid solution 11 can be stirred not only by the rotation of the rotary support 11 but also by the blade 25. The aim is to increase the rate of pickling.

In the present invention, as described above, the coil wire 16 is immersed in the pickling tank 10 in a vertical position so that the center axis of the inner circumference of the cylindrical coil wire 16 is in the vertical direction. Between the outer periphery of the coil wire 16 and the inner wall of the pickling tank 10,
There is no large unused (loss) area of the acid solution 2, which is caused by the conventional vertical base 4a' of the support arm 4 shown in FIG. It is possible to take an economical immersion mode with no waste by bringing it as close to the inner wall of the pickling tank 10 as possible, so that the entire acid solution 11 in this pickling tank 10 can be fully used for pickling without wasting it. When pickling the coil wire 16 of the same amount and size as in the past, the amount of acid solution used is much smaller than in the past, and moreover, the entire coil wire 16 dipped in this way is pickled in the acid solution 11. It rotates around a vertical axis 15 inside and is placed on a support 17 that allows the acid solution 11 to freely flow inside and outside the support 17 and is rotated while being pickled. Through this process, scale removal is significantly promoted, and the wire rod 1 is removed without leaving any parts that are insufficiently pickled.
6 can be pickled extremely uniformly and in a short time to completely remove scale, and the rotary support 17 has a vertical body 18 which is inserted through the coil wire 16 in the central axis direction. Flange portion 19 on which the lower end surface of the wire rod 16 is placed
Since it is constructed of , the coil wire 16 can be placed stably, and the support 17 can also be conveniently used as a carry for transporting the coil wire 16 by detaching it from the vertical shaft 15. Further, this device operates a coil wire 16 by a motor 13 on a suspension stand 12.
Since they only rotate the support 17, they are less likely to break and are more durable than the pickling structure that applies vibration to the entire suspension 3 as shown in FIG. A smaller one is sufficient compared to the vibration motor 6 shown in
In this respect as well, it has the advantage of being economical.
