Abstract

The utility model discloses an electromagnetic purifier for ferromagneto-micropowder in rolling oil. The device is composed of a filter box, a magnetic yoke, an iron core, a coil, magnetic poles, an inlet pipeline, an outlet pipeline, e tc. The filter box is arranged between two magnetic poles, and the interior of the box is filled with steel bars or steel balls. The ferromagneto-micropowder can be adsorbed on the steel bars or the steel balls when the rolling oil passes through between the steel bars or the steel balls, and thus, the utility model can achieve the purifying purpose. The device has simple structure.

Description

Electromagnetic purifier for ferromagneto-micropowder in rolling oil

The utility model relates to the electromagnetic cleaning means of ferromagnetism micro mist in a kind of electromagnetic cleaning means, particularly ROLLING OIL.

In modern steel rolling is produced, extensively adopt ROLLING OIL, its objective is in order to be lubricated between breaker roll and the band steel and breaker roll and band steel cool off.At present, not only in cold rolling production, adopt ROLLING OIL, but also progressively be generalized in the hot rolling production.In rolling process, attached to the iron scale on the steel strip surface, the tiny iron powder that iron rust and steel band are got off by roll wear etc., major part all is rolled oil and takes away, and these impurity will worsen the surface quality of band steel, the service life of reducing ROLLING OIL greatly.Because ROLLING OIL costs an arm and a leg, therefore domestic and international most of steel rolling mills all dispose the purifier of ROLLING OIL, and generally the purifier of Cai Yonging mainly contains Hard Magnetic magnetic drum formula, vacuum filter paper and centrifugal etc.These devices can be removed ferromagnetic particle thicker in the ROLLING OIL effectively, but the removal ability to ferromagnetism micro mist in the ROLLING OIL (as less than 10 microns) is very low, this is because particle diameter is bigger behind the ferromagnetism micro mist absorption one deck oil film in the ROLLING OIL, viscosity resistance also increases thereupon, the corresponding proportion that is reduced near ROLLING OIL of proportion makes the ferromagnetism micro mist to be suspended in the ROLLING OIL quite stable.If adopt Hard Magnetic drum device, then because magnetic field intensity is little, and magnetic drum is little to the attraction of ferromagnetism micro mist, effect is bad.In the Huffman device as select the filter paper in the superfine aperture phenomenon that very easily results in blockage again for use, and centrifugal device is to the subparticle nearly unavailable.Like this, the content of ferromagnetism micro mist can constantly accumulate with the use repeatedly of ROLLING OIL and increase in the ROLLING OIL, even can be agglomerated into greasy filth and worsen plate surface quality, quicken the wearing and tearing of rolling mill bearing and pollute working environment, can change whole ROLLING OIL because of using at last, cause great economic loss.

The purpose of this utility model just provides a kind of purifier that can effectively remove ferromagnetism micro mist in the ROLLING OIL.

To achieve these goals, the utility model proposes the design of the electromagnetic cleaning means of ferromagnetism micro mist in a kind of ROLLING OIL.The utility model is by Rose Box, yoke, iron core, coil, magnetic pole, compositions such as turnover pipeline, it is characterized in that Rose Box is contained between two electromagnetic poles, the rod iron of full magnetic conductivity in the case, the axis direction of rod iron is vertical with the magnetic line of force, leave between the rod iron less than 5 mm clearance, under the effect in magnetic field, the ferromagnetism micro mist in the ROLLING OIL just can be adsorbed on the rod iron, reaches the purification purpose when ROLLING OIL flow through between rod iron.

Adopted after the utility model, the ferromagnetism micro mist in the ROLLING OIL is almost all filtered clean, and ROLLING OIL outward appearance after filtering extremely cleans, and does not have the greasy filth that pollutes.Therefore not only the surface quality of steel band be improved significantly, outside bearing life improves greatly, also saved a large amount of ROLLING OIL expenses.With the Wuhan Iron and Steel Plant silicon sheet Plant is example, and before employing the utility model, milling train year consumes 500 tons of ROLLING OIL, and the price of ROLLING OIL is 15000 yuan/ton, has adopted after the utility model, and only ROLLING OIL is just saved 3,500,000 yuan an every year.In addition, workman's operating condition and working environment also are significantly improved.Of the present utility model in addition simple in structure, invest cheaply, easy to maintenance, and this device also can be used to purify other liquid medium such as emulsion etc., economic benefit and social benefit are very remarkable, and the excellent popularization prospect is arranged.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

Fig. 1 is the structure chart of the utility model purifier.

Fig. 2 is the A-A cutaway view of the utility model purifier.

1 is yoke among the figure, the 2nd, and iron core, the 3rd, coil, the 4th, magnetic pole, the 5th, Rose Box, the 6th, rod iron, the 7th, ROLLING OIL inlet tube, the 8th, hot water inlet pipe, the 9th, ROLLING OIL discharger, the 10th, the discharger of regenerated sewage.

As seen from the figure, the utility model forms magnetic loop by yoke 1, and iron core 2 is connected on the yoke, and solenoid 3 is housed on the iron core, and Rose Box 5 is placed between two magnetic poles, is full of the rod iron 6 of magnetic conductivity in the case, and the axis direction of rod iron is vertical with the magnetic line of force.Between magnetic pole, produce magnetic field after the coil electricity, after entering in the purifier casing, ROLLING OIL passes through the gap between the rod iron, under the effect of high-intensity magnetic field, tiny iron powder in the ROLLING OIL just is attracted on the rod iron, reach the purpose of purification, purification effects is relevant with the gap of magnetic field intensity and rod iron.Will determine the gap of magnetic field intensity and rod iron according to the situations such as treating capacity of the quantity of ferromagnetism micro mist in the ROLLING OIL, granularity, ROLLING OIL in the actual production, average magnetic field intensity is about 2000 Gausses in the present embodiment.The gap of rod iron should be less than 5 millimeters.This purifier is through being filled the ferromagnetism micro mist on the rod iron after the use of certain hour, influence treatment effect, so must be to the purifier processing of regenerating, elder generation is with the ROLLING OIL emptying during processing, under demagnetized state, hot water is sprayed in the case, directly wash the ferromagnetism micro mist on the rod iron, the regeneration period makes an appointment with half an hour for once a day at every turn.

The utility model purifier is independent of outside the original ROLLING OIL purifier of milling train, and ROLLING OIL is carried out purifying the second time.Therefore, the utility model purifier can be arranged in suitable place, workshop.If the place is narrow and small, a pair of coil and magnetic pole can be set, and a Rose Box, and yoke is vertically placed, one side, take up an area of to reduce being placed in the trench of coil is not installed.

In addition, in Rose Box, replace rod iron, can obtain same good effect with steel ball.
