[0075] By adopting the above technical solution:

[0076] 1. This equipment has an additional slag box compared to conventional similar equipment. The function of the slag box is to facilitate the cleaning of small particles in the slag removal box and filter out water at the same time. The small particles of slag are taken away and poured away, and the water in the slag box is pumped back to the slag removal box by the built-in water pump and discharged. It is convenient to clean the slag removal box and reduce the labor intensity of workers;

[0077] 2. The finishing structure adopts a split structure, which is convenient for transportation and installation. Separating the oil separator tank and the sewage lifting tank can facilitate transportation, and it is easier to install and carry in places where the equipment installation position is tight and the door is narrow;

[0078] 3. The oil separators on both sides of the oil collecting cone adopt an inclined box structure. The commonly used oil separators adopt a horizontal structure at the upper part of the outlet section (that is, the right part of the oil collecting cone).

[0080] 5. A sludge discharge pipe is added between the oil separator tank and the sewage lifting tank. The sewage pump in the sewage lifting tank can be used to discharge the sludge in the oil separator tank, making the cleaning work more convenient.

[0081] The oil-water separation equipment currently on the market is mostly controlled by time relays or PLC plus ordinary touch screen. It does not have oil level sensors and electric ball valves, and cannot achieve remote monitoring and control. It requires regular manual inspections and monitoring, which increases the personnel input of the equipment. In addition, the amount of grease produced cannot be counted and monitored. This system can help users accurately control the flow of grease and prevent recycled grease from flowing to catering venues.

[0082] In response to the above problems, this application uses intelligent sensors and touch screens that can be connected to the Internet to achieve remote monitoring and control via mobile phones, thereby saving labor costs and reducing labor intensity. The separated oil and fat are statistically analyzed to facilitate user management.

[0083] Working principle: Figure 1-4 As shown, the oily sewage enters the oil slag box of the equipment, and the large solid matter is separated from the sewage by the auger and filter net of the slag box and discharged into the trash can. The remaining oily sewage enters the oil separator, where the oil and water in the oil separator float due to different densities and are stored in the oil collecting cone. The remaining oil-free sewage is discharged into the sewage lifting tank through the drain pipe. The sewage in the sewage lifting tank is displayed by a float ball and discharged to the sewage treatment station or municipal pipe network by a sewage pump. The oil collecting cone is equipped with an oil level sensor. When the oil level sensor shows that there is oil, the oil discharge valve of the oil collecting cone can be opened to discharge the oil. The discharged oil enters the oil collecting barrel. The oil collecting barrel is placed on an electronic scale. The electronic scale can accurately know the weight of the oil barrel and notify the operator to replace the oil barrel in time. The oil filter net in the slag box. When there are more small slags in the slag box, it needs to be discharged to the slag box in time through the valve. The filtered sewage is pumped to the slag box by the sewage pump in the slag box and finally discharged.

[0084] The backwash system is used to remove solid matter attached to the filter screen in the slag removal box to prevent solid matter from clogging the leakage holes and causing sewage to overflow.

[0085] The aeration plate in the oil separator is connected to the oxygenator to generate tiny bubbles. The rising of the bubbles will drive the oil droplets in the sewage to float up quickly and concentrate in the oil collecting cone.

[0086] The sludge discharge pipe is used to discharge the sludge in the oil separator through the sewage lift pump. Regularly cleaning and discharging the sludge in the oil separator will improve the oil-water separation effect.

[0087] The function of the heating rod is to heat the grease separated in the oil collecting cone so that the grease can be discharged from the equipment smoothly.

[0088] The above equipment uses oil level sensors to sense the depth of the oil, so as to achieve the purpose of timely oil drainage; the electronic scale can be used to know whether there is an oil drain barrel under the equipment and the actual weight of the discharged oil, so as to achieve the purpose of actually controlling the direction of oil drainage.

[0089] The sewage pump in the slag discharge box is equipped with a float, which can achieve the purpose of automatic drainage according to the water level;

[0090] There is a float in the sewage lifting tank, and the sewage pump automatically starts and stops according to the position of the float;

[0091] The whole process of slag removal and oil separation is controlled by PLC. The operation time of slag removal auger, backwash pump, aerator and heating rod can be set through the touch screen of the control box according to the actual working time of the enterprise. The operation of the heating rod is also controlled by the temperature sensor, and the grease is heated according to the upper and lower temperature limits set on the touch screen. The upper and lower temperature limits are set according to the type of grease used by the user.
