Description

A kind of lubricating oil recycling device for cold-rolled

Technical field

The utility model relates to cold tube rolling production equipment technologies, and in particular to a kind of cold tube rolling lubricating oil recycling Device.

Background technique

Cold tube rolling is using the steel pipe of cold-rolling process production, and lubrication is extremely important in the technical process of cold tube rolling 's.The surface quality problems due to caused by faulty lubrication often appear in the production process of steel pipe, are especially producing in enormous quantities In as cleanliness of lubricating oil difference caused by steel tube surface quality problem it is very universal, therefore lubricate improper or lubricating oil it is unclean Great harm is caused to production.

At present during rolling, lubricating oil is constantly recycled, and is flowed down from pipe and is directly entered oil sump It mixes with the lubricating oil of lubrication head, is then ceaselessly squeezed into the circulatory system through oil pump.On pipe surface or When under the oil stream in the inner wall of core rod touch can by pipe surface iron filings particle, dust, oxidation bits etc. impurity bring oil into Chi Zhong pollutes lubricating oil, can aggravate the abrasion of equipment, shorten the service life of equipment.

The device of the recycling lubricating oil of the prior art needs to process by repeatedly precipitating, separating a few road process flows Journey is complicated, and the time is longer, influences the use of lubricating oil, influences the production efficiency of cold tube rolling.The lubricating oil that cold-rolling process uses Major impurity be iron filings, also containing the impurity such as a small amount of dust, paraffin, graphite, and the main reason for iron filings are equipment attritions.

Utility model content

The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, design is closed Reason, lubricating oil recycling device for cold-rolled easy to use.

In order to achieve the above purposes, the technical solution adopted by the utility model is:, and it includes oil sump, heating tube, precipitating bottom, falls Tapered coarse strainer, bracket, flowline, fine filter, oil pump, condenser, cooling water, can use lubricating oil pipe, decontamination at cone cell magnet Pipe, decontamination pump；The side wall of the oil sump is equipped with heating tube, and the bottom of oil sump is provided with precipitating bottom, the upper end setting of oil sump There is inverted cone-shaped coarse strainer, bottom is fixed with bracket in oil sump, and cone cell magnet is provided on bracket；The oil sump passes through flowline It being connect with fine filter, fine filter is connected by the oil inlet end of oil pump and condenser, cooling water is filled in condenser, condenser Oil outlet is connect with available lubricating oil pipe；It is connected with decontamination pipe on the precipitating bottom, decontaminates and decontamination pump is installed on pipe.

Preferably, being fixed with temperature sensor in the oil sump.

Preferably, being fixed with carrying handle on the bracket.

Preferably, the bracket of the inverted cone-shaped coarse strainer upper end and oil sump upper-end contact are arranged, it is fixed on bracket Handle.

Preferably, being inserted with refined filtration net in the fine filter.

When the utility model operates, the oil recovery flowed down from pipe is directly entered oil sump, first passes around inverted cone-shaped coarse filtration The coarse filtration of net filters out big impurity, and then thinner impurity passes through cone cell magnet, and iron filings are adsorbed by cone cell magnet, remaining Impurity is trickled downwards along the cone cell of cone cell magnet into bottom is precipitated, and the oil after precipitating is delivered to condenser by cooling water through oil pump It is cooling, fall fine impurities through refined filtration net filtration again in transmission process, can be available lubricating oil with the oil that lubricating oil pipe is gone out, The operation only needs the regular hour in settling step, remaining process, as long as oil is by filtering.

After adopting the above structure, the utility model is the beneficial effects are as follows: a kind of cold-rolled steel described in the utility model Pipe lubricant recovery device, recovery efficiency is high, and the time is short, high production efficiency, can be adequately filtered out iron tramp, avoids the mill of equipment Damage, the utility model have many advantages, such as that structure is simple, setting is reasonable, low manufacture cost.
