Description

Technical Field

[0001] The invention belongs to the field of water treatment, and specifically discloses an oil-water separation device with a slag removal function. Background Art

[0002] Sewage usually refers to the discharged water from life or production that is polluted to a certain extent. According to the source of sewage, it can be divided into industrial wastewater, domestic sewage, commercial sewage and surface runoff. Commercial sewage is non-toxic and harmless sewage from commercial facilities, and some components exceed domestic sewage, such as catering sewage, laundry sewage, animal breeding sewage, hair salon sewage, etc. In large and medium-sized cities, the proportion of commercial sewage is increasing, and oil pollution accounts for a large proportion of commercial sewage.

[0003] At present, most of the oil-water separators on the market cannot remove solid residues in the oil and water. Solid residues entering the oil-water separator are likely to block the oil outlet or the water outlet, requiring manual removal of the solid residues or continuous cleaning of the oil outlet and the water outlet, which brings great trouble to the work of the staff and reduces the work efficiency of the staff. At the same time, small-sized solid residues are directly discharged with the oil or water, which also brings certain harm to the ecological environment and affects people's work and life. Summary of the invention

An oil outlet is arranged on the side of the vacuum oil collecting box, and the oil outlet is connected with the oil outlet pipe; a vacuum pipe is arranged on the top of the vacuum oil collecting box, and the vacuum pipe is connected with the vacuum system; a water outlet is arranged at the bottom of the oil-water separation box, and a liquid inlet is arranged on the cone bucket box, and the liquid inlet is connected with the liquid inlet pipe;

[0007] A solid-liquid separation module, the solid-liquid separation module is integrated on one side of the oil-water separation module, the solid-liquid separation module comprises a solid-liquid separation box, a filter plate is arranged in the solid-liquid separation box, a feed port and a liquid outlet are arranged on the solid-liquid separation box, the feed port is located above the filter plate, the liquid outlet is located below the filter plate, the liquid outlet is connected to the liquid outlet pipe, the liquid outlet pipe is located above the liquid inlet pipe and communicates with the liquid inlet pipe.

[0008] As a further description of the above technical solution, a control valve is provided on the vacuum pipe and a stop valve is provided on the oil outlet pipe. The control valve can control the vacuum degree in the vacuum oil collecting tank. When the oil in the vacuum oil tank reaches the discharge volume, the control valve is closed and the stop valve is opened to facilitate the discharge of the oil.

[0009] As a further description of the above technical solution, the oil-water separation box is provided with an electric heating system. The heating system is combined with the vacuum system to prevent grease from hardening in the oil-water separation module and improve the oil-water separation efficiency.

[0010] As a further description of the above technical solution, a spiral slag discharger is provided in the solid-liquid separation box. The spiral slag discharger is arranged above the filter plate and can discharge the solid residue on the filter plate in time to prevent the solid residue from clogging the filter plate holes, thereby improving the solid-liquid separation effect.

[0011] As a further description of the above technical solution, the solid-liquid separation box is provided with an electric heating system, which can prevent the grease from being compacted in the solid-liquid separation box, avoid clogging the filter plate holes, and improve the solid-liquid separation efficiency.

[0012] As a further description of the above technical solution, a window is provided on the side of the vacuum oil collecting tank to facilitate observation of the oil level in the vacuum oil tank.
