Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

In the present invention, as shown in fig. 1 to 4, a drilling oil sewage treatment device is provided, which comprises a treatment tank 10 and a filtering mechanism, wherein the treatment tank 10 is provided with a liquid mixing cavity 101, a liquid inlet 102 and a liquid outlet 103 communicated with the liquid mixing cavity 101, and a gas dissolving spray head 104 is arranged in the liquid mixing cavity 101; filtering mechanism arranges in and mixes liquid chamber 101 upside, and filtering mechanism is including rotating piece 11, rotates piece 11 and is mixing liquid chamber 101 internal rotation, and it is equipped with and filters piece 12 to rotate piece 11, filters piece 12 and removes in mixing liquid chamber 101, filters piece 12 and includes filter residue portion 121 and oil absorption portion 122, and it extends to below inlet 102 to filter piece 12.

In the above structure, as shown in fig. 1 and 3, in one embodiment, the filter element moves from left to right in the liquid, during the process of treating oily water, the oily water is poured into the liquid mixing chamber 101 from the liquid inlet 102, at this time, the dissolved air nozzle 104 in the liquid mixing chamber 101 starts to work, and starts to generate micro-bubbles in the oily water, and the micro-bubbles contact with suspended matters in the sewage when floating upwards and are adsorbed in the flocculated suspended matters during the rising process, so that the particulate sewage in the sewage floats upwards to form scum on the surface of the water body. Be provided with filtering mechanism at mixing liquid cavity 101 upside, filtering mechanism's the in-process of rotating piece 11 at mixing liquid cavity 101 internal rotation, the drive filters piece 12 and removes in liquid, when having oily water in mixing liquid cavity 101, filter piece 12 and can stretch into oily water, filter piece 12 and remove in mixing liquid cavity 101, can scrape the collection with the dross that suspends on the water, thereby the dross that produces when effectual collection air supporting machine handles oily water, improve the treatment effect to oily water.

In addition, the filter element 12 is provided with the filter residue part 121 and the oil absorption part 122, the filter residue part 121 can effectively collect scum, and after the filter element 12 extends into oily water, the oil absorption part 122 can not completely remove oil substances in the water because the dissolved air nozzle 104 can not completely remove the oil substances in the water, so that the residual oil substances can still be mixed in the water, and the density of the oily soil is lower than that of the water, therefore, the oily soil can float on the surface of the water or be mixed with the water on the upper part of the liquid, and the oil absorption part can absorb the oily soil mixed on the upper part of the liquid and the oily soil floating on the surface of the liquid. When the filter element 12 collects scum, the oil substances mixed in the water cannot be adsorbed, and the water mixed with the oil substances is discharged, which is very easy to cause ecological problems, so that the oil absorption part 122 is arranged to adsorb the oil substances in the water, thereby improving the water treatment effect.

In a preferred embodiment, as shown in fig. 4, the residue filtering part 121 is a residue filtering plate, the residue filtering plate is provided with a plurality of filtering holes 1211, one side of the residue filtering plate is connected with the rotating member 11, the oil absorbing part 122 is connected to the lower side of the residue filtering plate, and the oil absorbing part 122 comprises an oil absorbing sponge 1221.

Structural at filtering piece 12, be equipped with a plurality of filtration pores 1211 on the filter residue board, filter piece 12 when mixing the intracavity 101 removal, the filter residue board can be effectual with water filtration to collect the dross, use the filter residue board can improve the structural strength of filter, remove the in-process in the aquatic, can support the resistance effect of water-resistant, scrape the dross and move and collect, and oil absorption portion 122 is including oil absorption sponge 1221, the in-process that the filter residue board removed in liquid, oil absorption sponge can effectively adsorb the greasy dirt of mixing in the aquatic. The scum is collected by using the scum board and the oil absorption sponge 1221, and oil substances leaked from the dissolved air nozzle 104 are absorbed at the same time, so that the treatment effect on the oily water is further improved.

Because the oil absorption sponge 1221 is made of a lighter material, after the filtering member enters the liquid, the oil absorption sponge 1221 can float upwards, so that oil stain collection on the surface of the liquid is completed.

In an embodiment, be equipped with the rubber backup pad at the oil absorption sponge back, increase the rubber backup pad, can effectual improvement to inhale the holding power of oil absorption sponge.

In a preferred embodiment, as shown in fig. 1 and 2, the filter device further comprises a material collecting mechanism, the material collecting mechanism is disposed in the liquid mixing chamber 101, the material collecting mechanism comprises an oil collecting member 13, the oil collecting member 13 is disposed on one side of the moving path of the filter member 12, the oil collecting member 13 comprises a squeezing table 131, the squeezing table 131 is obliquely disposed in the liquid mixing chamber 101, a scraping plate 133 is disposed at one end of the squeezing table 131 close to the oil absorbing sponge 1221, and the squeezing table 131 is provided with an oil collecting port 132, so that when the filter member 12 moves to the oil collecting member 13, the scraping plate 133 abuts against the oil absorbing sponge 1221.

In the above structure, the collecting mechanism is installed in the liquid mixing cavity 101, wherein the oil collecting piece 13 is installed on one side of the moving path of the filtering piece 12, so that the filtering piece 12 can contact with the oil collecting piece 13 when moving in the liquid, in addition, because the extrusion table 131 is obliquely arranged in the liquid mixing cavity 101, the oil absorption sponge 1221 is enabled to pass through the extrusion table 131, the scraper 133 at one end of the extrusion table 131 abuts against the oil absorption sponge 1221, oil stains in the oil absorption sponge 1221 are scraped and extruded, the extruded oil stains flow into the oil collecting port 132, and the collection is completed, so that the oil absorption sponge 1221 can ensure a better oil absorption effect when entering the next process, thereby improving the recycling efficiency of the oil absorption sponge 1221, and also can effectively collect oil substances, thereby improving the collection utilization rate of the oil substances.

More specifically, as shown in fig. 2, a plurality of pressing tables 131 are provided, and the plurality of pressing tables 131 are arranged in a stepwise manner.

The plurality of squeezing platforms 131 are arranged in a stepped manner in the liquid mixing cavity 101, so that the rotating member 11 contacts with the plurality of squeezing platforms 131 in the process of driving the filtering member 12 to move, the oil absorption sponge 1221 is scraped and squeezed by the scraping plates 133 for multiple times, and oil stains on the oil absorption sponge 1221 are further squeezed out. Set up a plurality of extrusion platforms 131 and extrude oil absorption sponge 1221, the effectual greasy dirt of extruding is collected, further environmental protection.
