いる。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an oil mist recovery device in a rolling equipment, and in particular, in a rolling equipment, a plurality of rolling mills are arranged in series, and a type of oil mist is collected for each classified rolling mill. [Background of the Invention] In rolling equipment, rolling oil is used for cooling and lubricating the rolls of the rolling mill and the objects to be rolled. During rolling operations, oil becomes oil mist, which deteriorates the surrounding environment. In addition, the amount of oil mist scattered is enormous, and
Rolling oil is wasted. Therefore, it is desired to efficiently suck this oil mist from around the rolling mill and to recover and reuse the sucked oil mist. Conventionally, in order to prevent environmental deterioration, an open hood was placed above the rolling mill, and the oil mist sucked together with air from the open hood was collected by a mist collector installed in the middle of the exhaust duct, and the oil mist was removed. The purified air is released into the atmosphere.

いため、吸引されない油ミストが周囲に拡散して、作業
環境の悪化をもたらすという欠点があった。Since the conventional open hood exhaust method has a large air suction area, the amount of exhaust air is large. For this reason,
The capacity of the exhaust duct, mist collector, and exhaust fan connected to the open hood must be increased, which increases the amount of equipment and operating costs.In addition, it is difficult to reliably suck in oil mist, so oil that is not sucked in There was a drawback that the mist spread to the surrounding area, causing a deterioration of the working environment.

Further, since the area around the rolling mill is a chamber isolated from the outside atmosphere, the oil mist generated from the rolling mill can be efficiently sucked, and the oil mist does not diffuse into the outside atmosphere. Therefore, a good working environment can be maintained.

The rolling equipment shown in the figure has five rolling mills arranged in series, and the first four rolling mills 12 are equipped with a work roller 14 and a pressure roller 16, and use the same type of rolling oil. 14A is the spindle of the work roll 14, 14B is the gear box, 14C
is the motor. The final rolling mill 18 includes work rolls 14,
It is equipped with a pressure roll 16 and an intermediate roll 20, and uses a different type of rolling oil from the four rolling mills 12. The steel plate 22 is rolled by the rolling mill 12.18 and finally wound onto a carrousel reel 23. Reference numerals 24 and 25 denote oil pans, and rolling oil stored in this oil pan is pumped up by an oil pump (not shown) and injected to the rolling mills 12 and 18. The surroundings of the rolling mill 12, 18 and the carousel reel 22 are divided and isolated from the outside atmosphere by a chamber. That is, it includes a chamber 26 that commonly accommodates the first four rolling mills 12, a chamber 28 that accommodates the rolling mill 18, and a chamber 30 that surrounds the carousel reel 22. The chamber 26 and the chamber 28 are separated by a partition plate 36, and as shown in FIG. 2, both chambers 26 and 28 are separated from the outside by at least a side plate 32 that can be opened and closed, at least a part of the operation surface side. The chamber 26.28 hermetically surrounds the rolling mill 12.18 on the sides and above, and is open on the lower side of the side plate 32 as an air intake. The chamber 30 has a shape similar to an open hood. Further, three air suction ports 44 are connected to the ceiling surface 42 of the chamber 26 at appropriate locations, and each air suction port 44 is connected to a duct 46 of the first system. The suction port 44 is the duct 46
A damper 48 is provided at a position connected to the damper 48, and the amount of air sucked is adjusted by the damper 48, and a part of the oil mist in the sucked air is transferred to the damper 48.
It collides with and liquefies. The bottom surface of the duct 46 has a wave-shaped inclined surface with a small slope, and the oil mist liquefied by colliding with the damper and the oil mist liquefied while passing through the duct are collected in the concave portion 50 of the duct 46. A small-diameter pipe line 52 is connected to each of the recesses 50, and one end of each pipe line 52 is connected to the oil pan 24. Therefore, the oil mist liquefied in the duct 46 is collected from the concave portion 50 on the bottom of the duct through the conduit 52 to the oil pan 24 and reused. Further, a first system primary mist collector 54 is provided on the downstream side of the duct 46, and most of the oil mist is collected by this primary mist collector 54. The collected oil mist is collected in the oil pan 24 via the pipe 56 and reused. Air suction ports 58 and 60 are connected to the chambers 28 and 30 in the same manner as described above, and communicate with the duct 62 of the second system. The oil mist liquefied in this duct 62 and the oil mist collected by a second system primary mist collector 64 provided at the rear of the duct pass through a pipe line 66.
It is collected in the oil pan 25 and reused.

なった圧延油の混合物であるから、再利用ができない。After removing most of the oil mist by the mist collectors 54, 64, the suction air from each chamber is combined and discharged to the atmosphere via the final mixed mist collector 68. Since the oil mist collected by the mist collector 68 is a mixture of different types of rolling oil, it cannot be reused.
従って管路７０を経て、廃油槽７２に貯えた混合油は廃
棄その他の処理処分を行う。Therefore, the mixed oil stored in the waste oil tank 72 via the pipe 70 is disposed of or otherwise disposed of.

Collect in one line. Further, the rolling oil used in the rolling mill 12 is different from the rolling oil used in the rolling mill 1 which uses a different type of rolling oil.
8 and the subsequent carousel reel 23 are enclosed in independent chambers 28 and 30, and the oil mist generated from these devices is collected by a second system. Therefore, the rolling oil collected for each system can be returned to the original oil pan 24 or 25 and reused.

雰囲気即ち作業環境を良好に保つことができる。Each chamber is isolated from the outside atmosphere, and the opening for taking in outside air is kept to the minimum necessary, with only the lower part on the operation surface side of the rolling mill. Therefore, the oil mist generated from the rolling mill can be reliably sucked with a minimum amount of suction air. Therefore, the capacity of the duct, mist collector, and exhaust fan can be reduced, which contributes to a reduction in equipment costs and operating costs, and it is possible to maintain a good external atmosphere, that is, a working environment.

きる。This oil cleaning means is used when the rolling mill stops operating.
It is effective for washing away oil stuck to the inner surface of the duct or mist collector element. Also, when changing the rolling oil, by washing off the oil stuck to the inner surface of the duct, etc., it is possible to mix it with the newly used rolling oil. Mixing can be prevented.

An intake fan (not shown) provided at the rear end of the bleed air duct 162, 164, 166 allows the air in the stand chamber 120 to be divided into two air streams A and B as shown by the arrows in FIG.
It flows like this. That is, the airflow A rises along the front surface of the mill stand and is sucked in from the intake duct 160.
and through the roll to the upper vent 12 of the intermediate wall 123.
5 and reaches the spindle chamber 120. Here, without the intermediate wall 123, the airflow would flow through a relatively low part of the mill stand, making it easier for the upper part to fill with fume. In particular, J:♂ flow along the front surface becomes difficult to generate, and air containing mist may leak from the gap in the front door, contaminating the surrounding area.

離回収される。After passing through the intermediate wall 123, the airflow in the stand chamber 120 enters the spindle chamber 121, which has a large space, where the airflow speed rapidly decreases. Therefore, the rolling oil droplets moving on the air current are separated and removed. Further, the mist contained in the airflow is separated and collected by primary mist collectors 163, 165, and 167 provided in the air extraction duct.

油を再利用することができる。According to the present invention, oil mist generated from a rolling mill can be reliably sucked in with a minimum suction air volume, and a good working environment can be maintained. Further, even when oil mist with different properties is generated from a plurality of rolling mills, the oil mist having common properties can be collected in a separate system, so the collected oil can be reused.
