The invention discloses an oil-water separation and
recovery device for the catering industry. The device comprises an
oil separation tank, a feeding box and a
discharge tank, the
oil separation tankis respectively connected with the feeding box and the
discharge tank through pipelines, the feeding box is higher than the
oil separation tank, and the oil separation tank is higher than the
discharge tank. The oil separation tank comprises a tank body, a core tube and a filter layer, the filter layer is arranged at the lower part in the tank body, and divides the internal of the tank body into an
oil water cavity and a water inlet cavity, the side surface of the upper part of the
oil water cavity is provided with an oil discharge port, and the top of the
oil water cavity is provided with a gas discharge port; the core tube is inserted into the tank body from top to bottom, the lower end of the core tube is located in the water inlet cavity, the top of the core tube is connected with a downcomer and a
siphon tube respectively, the other end of the downcomer is connected with the feeding box, the other end of the
siphon tube is connected to the discharge tank, and the highest point ofthe
siphon tube is lower than the bottom of the feeding box and higher than the oil discharge port; and the oil-water separation and
recovery device further comprises a blow-down tube, one end of theblow-down tube is inserted into the tank body, the other end is bent and then is connected to the highest point of the siphon tube, and the highest point of the blow-down tube is higher than the highest point of the siphon tube.
