As shown in fig. 1 to 3, the embodiment of the utility model provides a processing apparatus before oily dirty floater sewage sets up in the water inlet end of sewage treatment pond for separate the greasy dirt floater in the sewage. The device comprises a sewage draining channel 1, a separating conveyor belt 2, a cleaning piece 3, a driving piece, a sewage collecting groove 4 and the like.
The blowdown canal 1 is connected with the drain and the inlet end of the sewage treatment tank, and sewage flows into the sewage treatment tank through the blowdown canal 1.
The separation conveyor belt 2 is arranged in the sewage draining channel 1 and is obliquely and upwards arranged along the water flow direction of the sewage draining channel 1. The width of the separation conveyor belt 2 is slightly smaller than that of the sewage draining channel 1; when the sewage draining channel is obliquely arranged, the lower part of the separation conveying belt 2 is submerged below the sewage water surface, and the upper end part of the separation conveying belt 2 extends to the outer side of the upper part of the sewage draining channel 1.
And the driving piece is in transmission connection with the rotating shaft 22 at the upper end of the separation conveyor belt 2 and drives the separation conveyor belt 2 to rotate obliquely upwards. When the separating conveyor belt 2 rotates upwards in an inclined way, the upper surface of the separating conveyor belt passes through the surface from the lower part of the sewage surface in an inclined way, so that oil stain floaters floating on the sewage surface are attached to the separating conveyor belt 2 and are lifted upwards out of the water surface along with the operation of the separating conveyor belt 2; after the separation conveyor belt 2 runs over the highest point, the attached oil stain floater can fall off under the action of gravity and is separated from the water body by the separation conveyor belt 2.

The arc-shaped convex edges 21 are arranged, so that when the separation conveyor belt 2 lifts the oil stain floater, the oil stain floater can be effectively prevented from sliding back to the water body, and the separation effect of the oil stain floater and the water body is enhanced.
The separation conveyor belt 2 is a mesh conveyor belt, the aperture of the mesh on the separation conveyor belt is preferably less than or equal to 3mm, such as 3mm, 2.5mm or 2mm, oil stains, floating objects such as animal tissues and animal hairs are guaranteed to be effectively intercepted, and water flow is guaranteed to smoothly pass through.
In one embodiment, the cleaning element 3 is a brush roller, which is connected to a drive element and is driven in rotation by the drive element. And the rotating direction of the brush roller and the corresponding part of the separation conveyor belt 2 contacted with the brush roller move reversely, so that oil stain floaters and the like attached to the separation conveyor belt 2 can be completely scraped. It is obvious that the cleaning elements 3 can also be flexible scrapers mounted stationary, which by contact with the separating conveyor 2 effect the scraping off of oil-soiled floating material.
Specifically, as shown in fig. 1 to 3, the driving member includes a driving motor 5, a first driving wheel 52 is coaxially mounted on an output shaft 51 of the driving motor 5, and the first driving wheel 52 is in transmission connection with the end of the rotating shaft 22 at the upper part of the separation transmission belt 2 through the belt 6. The separation conveyor 2 is driven to rotate by a drive motor 5.
The output shaft 51 of the driving motor 5 is further provided with a second driving wheel 53, that is, the second driving wheel 53 and the first driving wheel 52 are both positioned on the output shaft 51 and coaxially arranged. The second driving wheel 53 is in transmission connection with the end part of the brush roller through the belt 6, the driving motor 5 drives the separation conveying belt 2 to operate, the brush roller is driven to rotate and operate simultaneously, the brush roller rotates in the same direction with the rotating shaft 22, and the outer surface of the brush roller and the contact part of the separation conveying belt 2 reversely operate.
As shown in fig. 2 and 3, the two sides of the separation conveyor belt 2 are provided with side plates 23, and a baffle 7 is further arranged between the outer side of each side plate 23 and the side wall of the sewage discharge channel 1 to prevent sewage from flowing through a gap between the side plate 23 and the side wall of the sewage discharge channel 1, so that the sewage can pass through the sewage discharge channel 1 after being completely filtered and separated by the separation conveyor belt 2, and the oil and dirt floaters are completely separated.
And the lower end of the separation conveyor belt 2 is arranged close to the bottom of the sewage discharge channel 1, so that oil stain floaters in sewage which cannot be well separated when the water level is too low are avoided.
To sum up, the utility model discloses a dirty floater sewage pretreatment device of oiliness sets up the ascending separation conveyer belt 2 of slope in blowdown canal 1, and separation conveyer belt 2 has the mesh, but water supply flow flows through and intercepts the greasy dirt floater, realizes the greasy dirt floater on sewage upper portion and water separation through the upwards operation of separation conveyer belt 2, and the greasy dirt floater is along with the transportation of separation conveyer belt 2, sweeps through cleaning member 3 and collects into dirty groove 4 of collection. The device can intercept and separate the oil stain floater in the sewage continuously, and has the advantages of simple structure, convenient operation and maintenance, good separation effect and high efficiency.
