The sewage inlet 11 is used to transport oil pollutants into the box body 1, the liquid inlet is used to replenish the liquid in the box body 1, and the sewage outlet 13 is used to discharge sediment. Figure 1 In this embodiment, the sewage inlet 11 is opened on the right side wall of the box body 1, and the liquid inlet 12 and the sewage outlet 13 are opened on the left side wall of the box body 1, and the height of the liquid inlet 12 is higher than the height of the sewage inlet 11, and the height of the sewage inlet 11 is higher than the height of the sewage outlet 13. The initial oily pollutants enter the box body 1 through the sewage inlet 11 for deoiling, and the solid sediment after deoiling is discharged through the sewage outlet 13, and the liquid is replenished in the box body 1 through the liquid inlet 12. Preferably, in this embodiment, the box body 1 is wrapped with sound-absorbing cotton on all sides to achieve the effect of silencing and reducing noise.

[0032] The universal movable bracket 2 is movably installed on the top of the box body 1. The universal movable bracket 2 can move and rotate relative to the top of the box body 1. Figure 2 As shown, in the present embodiment, the middle end of the outer wall of the universal movable bracket 2 is horizontally recessed from the edge to the center to form a slide groove 21. The universal movable bracket 2 is installed by plugging the slide groove 21 into the upper cover of the box body 1. A plurality of balls 211 are provided on the inner top wall of the slide groove 21. The balls 211 drive the universal movable bracket 2 to move forward, backward, left and right and rotate on the upper cover of the box body 1. Preferably, in the present embodiment, a motor 22 is also provided on the universal movable bracket 2. The motor 22 is used to drive the universal movable bracket 2 to rotate, realize automated operation, and improve the working efficiency of the ultrasonic deoiling equipment; preferably, in the present embodiment, shock-absorbing sliding pads 212 are provided on the upper and lower inner walls of the slide groove 21 to reduce the vibration of the universal movable bracket 2 during the movement and rotation process, thereby ensuring the stable operation of the entire ultrasonic deoiling equipment.

[0033] The ultrasonic deoiling device 3 includes an ultrasonic generator 31, an ultrasonic focusing probe 32 and an ultrasonic coupling vibration plate 33. The ultrasonic focusing probe 32 is fixedly mounted on the universal movable bracket 2. The universal movable bracket 2 can drive the ultrasonic focusing probe 32 to freely move to surrounding positions within a certain range, and can also drive the ultrasonic focusing probe 32 to make circular motion, so that the ultrasonic focusing probe 32 can have a larger range of action and a more uniform action. The detection end of the ultrasonic focusing probe 32 penetrates the universal movable bracket 2 and extends into the box body 1, so as to perform ultrasonic deoiling on the oil-containing pollutants in the box body 1.

[0034] The ultrasonic coupling vibration plate 33 includes a partition 331 and a plurality of ultrasonic transducers 332. The plurality of ultrasonic transducers 332 are coupled to one side of the partition 331. The partition 331 acts as a vibration plate. In this embodiment, the partition 331 and the plurality of ultrasonic transducers 332 in the ultrasonic coupling vibration plate 33 are connected by adhesive bonding, that is, the ultrasonic transducer 332 and the partition 331 are connected by adhesive bonding. The contact surface between the ultrasonic transducer 332 and the partition 331 is sandblasted and then glued with glue. The specific process is sandblasting, cleaning dust, drying and preheating, gluing, and pressurizing and heating to cure. After gluing, the coupling effect is judged by detecting the gluing impedance of each ultrasonic transducer 332. The gluing impedance of each ultrasonic transducer 332 cannot exceed the specified value, otherwise it is removed and re-glued. The ultrasonic coupling vibration plate 33 is installed at the lower end of the box body 1, and one end of the ultrasonic transducer 332 is placed downward.

[0035] The present invention uses ultrasonic wave to remove oil. As a special form of energy, ultrasonic wave will produce cavitation, mechanical and thermal effects when propagating. The ultrasonic cavitation effect will produce local high temperature (5000K) and high pressure (5×10 4kPa) phenomenon, and the high-intensity shear force generated by the annihilation of cavitation bubbles, as well as the free radicals of hydroxyl and hydroxyl groups with strong oxidizing ability generated thereby, can strengthen the local surface characteristics and improve the solid-liquid separation performance. Compared with other treatment methods, ultrasonic treatment is not easy to produce secondary pollution, has a higher resource recovery rate, effectively improves energy utilization, and has broad engineering application prospects. In this embodiment, the ultrasonic frequency, power and action time of the ultrasonic energy focusing probe 32 and the ultrasonic transducer 332 are independently and continuously adjustable through the ultrasonic generator 1, and the ultrasonic energy focusing probe 32 and the ultrasonic transducer 332 can also be selected to be turned on or act in synergy according to specific working conditions. Therefore, the ultrasonic deoiling equipment provided by the present invention can treat a wide range of oil-containing pollutants. For oil-containing pollutants of different types and characteristics, the optimal ultrasonic treatment working conditions can be configured to achieve the best deoiling effect and improve the deoiling efficiency.

The floating oil collecting head 41 is provided with an oil collecting inlet and an oil collecting outlet connected to the oil collecting inlet. The oil collecting inlet is used to collect free oil floating on the surface of the tank body 1. One end of the oil collecting pipe 42 is connected to the oil collecting outlet, and the other end extends out of the tank body 1 and is connected to the oil container. The oil collecting pipe 42 is used to transport the oil collected by the floating oil collecting head 41 to the storage container. In this embodiment, the oil collecting pipe 42 adopts a soft pipe.

[0038] Preferably, an oil pump 43 is provided between the oil collecting pipe 42 and the oil container. After the oil collecting head 412 collects the oil layer, the oil is collected through the oil collecting pipe 42 under the action of the oil pump 43 .

[0039] The ultrasonic deoiling device provided by the present invention has the following working process: firstly, oil solid pollutants are placed in a box body 1 through a sewage inlet 11, and water is added into the box body 1 through a liquid inlet 12. When the liquid level reaches a certain height, the ultrasonic generator 31 is turned on. According to the oil-containing properties of the solid waste, a specific working condition is selected, and the frequency, power and action time of the ultrasonic energy focusing probe 32 and the ultrasonic transducer 332 are adjusted respectively. The two can be turned on separately or act in coordination. The optimal action position of the ultrasonic energy focusing probe 32 is adjusted by a universal movable bracket 2, and the motor 22 is turned on to make the ultrasonic energy focusing probe 32 perform a circular motion within a certain range to increase the uniformity of the ultrasonic effect. After the ultrasonic action stops, the oil contained in the solid pollutants is desorbed and floats on the liquid surface. The oil is collected by an oil collecting head 412 floating on the liquid surface. At the same time, the oil pump 43 in the oil suction device is turned on to uniformly collect the oil collected in the oil collecting head 412. After the oil collection is completed, the waste liquid sediment in the box body 1 is discharged from the sewage outlet 13.
