Detailed Description

The technical solution of the present invention will be described in further detail with reference to specific embodiments.

In the description of the present invention, it should be noted that the terms "inside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 and 2, the present invention provides a dry-wet separated cooling oil slag discharging device, which comprises a slag scraper 10 and a plurality of magnetic iron scrap separators 12.

Wherein, the magnetic iron scrap separator 12 is used for separating iron scrap in the cooling oil by a strong magnet (not shown) before the cooling oil is filtered by a filtering device (not shown); the residue scraper 10 is used for back flushing the precipitated residual oil in the residue scraper 10 after the filtering device is filtered for a long time, then precipitating to further recover the oil in the residue scraper 10, and discharging the residual oil with higher final concentration. In the existing structure, scrap iron in a magnetic scrap iron separator is provided with a special recovery device for receiving and recovering the scrap iron; the slag scraper is also provided with a special recovery device to receive residual oil, so that the subsequent treatment is convenient; this structure needs two recovery unit, and the structure is complicated, take up an area of greatly, and is unfavorable for the oil-liquid separation in the iron fillings, causes certain waste. Scrap iron is also fed into the slag scraper in a uniform treatment manner, but this increases the workload of the slag scraper and increases the wear of the scraper therein.

Therefore, the invention adopts the following structure:

the residue scraper 10 comprises a hollow case 14, a residue pipe 16 for conveying residue is communicated with the case 14, a residue discharge port 22 is arranged on the case 14, a conveyor belt 20 is horizontally arranged on the case 14, one end of the conveyor belt 20 is positioned above the residue discharge port 22, and a driving motor 24 drives the conveyor belt 20 to circularly rotate between the two horizontally arranged conveyor rollers.

The magnetic iron scrap separator 12 is used for separating iron scraps from cooling oil, and the magnetic iron scrap separator 12 comprises an iron scrap outlet 26 positioned above the conveyor belt 20. The top of each magnetic iron chip separator 12 is provided with a cooling oil inlet 28, the bottom of each magnetic iron chip separator 12 is provided with a funnel-shaped oil receiving bucket 30, and the bottom of the oil receiving bucket 30 is provided with a cooling oil outlet. When the magnetic iron scrap separator is used, cooling oil enters the magnetic iron scrap separator 12 from the cooling oil inlet 28, iron scraps in the magnetic iron scrap separator are adsorbed under the action of strong magnets, and then the iron scraps fall onto the conveyor belt 20 from the iron scrap outlet 26 and are discharged from the conveyor belt 20 through the slag discharge port 22. On the conveyor belt 20, the oil contained therein drops into the lower cabinet 14, thereby avoiding being discharged, and improving the oil recovery efficiency. The scrap iron is directly discharged without entering the slag scraper 10. The structure and principle of separating iron pieces by the magnetic iron piece separator 12 can be seen in the antecedents 202022608701.7, 202022604702.4 and the like of the present application, which are described in detail, and the structure itself is not the innovation point of the present invention, so that the details are not described.

Furthermore, an overflow-preventing port 32 is arranged on the case 14, and the overflow-preventing port 32 is communicated with an oil return pipeline 34; the liquid level inside the slag scraper 10 is prevented from being too high, and when the liquid level is too high, the oil liquid in the slag scraper can flow back to the filtering device through the oil return pipeline 34.

Further, an oil discharge pump 36 is disposed in the casing 14, and the oil discharge pump 36 is connected to an oil discharge line 38. The oil discharge pump 36 is used for discharging the oil liquid obtained through precipitation and separation in advance before slag scraping so as to recycle the oil liquid, thereby improving the oil liquid recycling efficiency and improving the slag discharging efficiency of the slag scraper 10 (the dry residual oil is easier to be scraped by the scraper 42).

Furthermore, two annular transmission chains 40 are symmetrically arranged in the case 14, the transmission chains 40 extend from the bottom of the case 14 to the slag discharge port 22, and a plurality of scraping plates 42 are arranged between the two transmission chains 40.

Further, an oil mist cover 44 is disposed on the top of the cabinet 14 to prevent oil mist in the cabinet 14 from escaping.
