TECHNICAL FIELD

[0001] The utility model relates to oil dirt separation technical field, especially a water collecting well oil dirt cleaning device oil water separation mechanism. BACKGROUND

[0002] Mechanical wear and tear and aging of parts and other defects will cause certain oil leakage in the operation process of the electromechanical equipment of the hydropower station, and the oil and water are all converged to the water collecting well through the pipeline. In order to ensure that the oil dirt is not discharged into the downstream river, the oil dirt in the water collecting well is often treated by the method of artificial regular cleaning, but on the one hand, the air in the water collecting well is not ventilated, the environment is dark and damp, and the safety risk of manual operation is great; on the other hand, the operation workload is large, the labor intensity is high, the effect of artificial cleaning is not ideal, and a small part of oil dirt will still be discharged into the river, affecting the safety of downstream water quality.

[0003] Some oil water separation equipment used by artificial in the prior art cannot achieve the effect of good oil water separation and respective treatment, and a certain amount of oil dirt will still remain in the water. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the problem of poor oil dirt and water separation effect in the cleaning of the water collecting well in the prior art, the utility model provides a water collecting well oil dirt cleaning device oil water separation mechanism.

[0005] The technical scheme adopted by the utility model is:

[0006] A water collecting well oil dirt cleaning device oil water separation mechanism, comprising a water storage pool and a pipeline separation mechanism arranged on the water storage pool, a water filtering hole is formed in the pipeline separation mechanism, the inlet end of the pipeline separation mechanism is used for connecting the water collecting well side wall drain pipe, and the outlet end of the pipeline separation mechanism is connected with a transmission storage control device.

[0007] The pipeline separation mechanism comprises a pipeline support frame arranged on the water storage pool and a U-shaped filter pipeline arranged on the pipeline support frame, and the water filtering hole is formed in the bottom of the U-shaped filter pipeline.

[0008] Further, the pipeline support frame comprises a transverse support and a longitudinal support, the transverse support is fixedly connected with the longitudinal support, and the two ends of the transverse support and the longitudinal support are arranged on the pool wall of the water storage pool respectively.

[0009] Further, the U-shaped filter pipeline is a multistage circulation structure, the U-shaped filter pipeline is composed of a plurality of straight pipe sections and elbow sections connected in sequence, and a pipeline clamp is arranged between adjacent straight pipe sections.

[0010] Further, a filter cloth layer is arranged on the pipeline separation mechanism, and the filter cloth layer is attached to the outer surface of the pipeline separation mechanism and covers the water filtering hole.

[0011] The beneficial effects of this utility model are:

[0012] This utility model's oil stain cleaning device separates water and oil in the liquid flowing into the side wall of the collection well using an oil stain separation device. The water portion is filtered through the filter holes and collected in the storage tank below, while the oily portion is blocked through the filter holes and retained in the pipeline separation mechanism. It then enters the oil collection tank of the transmission and storage control device through the outlet end of the pipeline separation mechanism for collection, thereby achieving complete separation of water and oil. This effectively prevents incomplete oil from flowing into rivers with the water flow, avoiding environmental pollution. Compared with manual cleaning, this utility model's device can achieve automatic separation, with good separation effect, saving time and high efficiency. The U-shaped filter pipe design allows the mixed liquid to have a longer flow path and a longer residence time in the pipeline separation mechanism, resulting in more thorough oil-water separation and further improving the separation effect.
