[0034] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figure 1-3 The ultrasonic waste oil treatment device provided in this embodiment includes a housing 1 and an ultrasonic reactor 2 arranged in the housing;

[0036] The ultrasonic reactor 2 comprises a shell 21 and a plurality of ultrasonic generators, the plurality of ultrasonic generators are evenly arranged on the outer surface of the shell, and the waste oil outlet pipe 22 arranged at the upper end of the shell and the waste oil inlet pipe 23 arranged at the lower end both extend out of the shell and communicate with external pipelines;

[0037] The housing 21 is provided with a heating coil 3 .

[0038] In this embodiment, the heating coil is arranged at the middle and lower part of the ultrasonic reactor to heat the waste oil in the middle and lower part. As the waste oil flows, the heat is gradually transferred to the waste oil in the upper part of the ultrasonic reactor. The heat of the heating coil can reduce the viscosity of the waste oil and improve its fluidity. In combination with the cavitation and warming effect of the ultrasonic wave of the ultrasonic generator, the small oil droplets are better aggregated into large oil droplets, and the small water droplets are aggregated into large water droplets. At the same time, the solid matter can also be aggregated, which improves the separation effect of the oil-water-solid three-phase and the demulsification effect. After the waste oil enters the waste oil inlet pipe 23, it passes through the shell 21 of the ultrasonic reactor 2 from bottom to top. In this process, the waste oil is demulsified and the oil-water separation process is completed under the action of the uniformly distributed ultrasonic field, and then flows out of the ultrasonic reactor through the waste oil outlet pipe 22 and enters the subsequent separation unit. The ultrasonic action time can be adjusted according to the waste oil flow rate. While the waste oil passes through the ultrasonic reactor 2, the heating coil 3 inside it indirectly heats the waste oil, increases the fluidity of the waste oil, and improves the demulsification effect.

[0039] The utility model discloses an ultrasonic waste oil treatment device, which heats the waste oil through a heating coil arranged inside an ultrasonic reactor, so that the viscosity of the waste oil is reduced and the fluidity is increased, which facilitates the better aggregation of oil, water, solid and liquid droplets, and is combined with the cavitation, warming and other effects of the ultrasonic wave generated by the ultrasonic reactor of the ultrasonic generator, which can improve the separation effect of oil, water and solid and ensure the emulsification effect.

[0040] In a specific embodiment, the shell includes a shell body 211, an upper cover plate 212 arranged on the upper side of the shell body, and a lower cover plate 213 arranged on the lower side of the shell body; the dirty oil outlet pipe is arranged on the upper cover plate, and the dirty oil inlet pipe is arranged on the lower cover plate; the ultrasonic generator is arranged on the shell body; the dirty oil outlet pipe is welded to the upper cover plate as a whole, and the dirty oil inlet pipe is welded to the lower cover plate as a whole, which is convenient for disassembly and assembly; the ultrasonic wave generated by the ultrasonic generator is transmitted through the shell wall of the shell body to the dirty oil liquid introduced into the shell, and ultrasonic cavitation and warming are performed on the dirty oil to ensure the demulsification effect;

[0041] The heating coil 3 is provided with a plurality of bends, which form a plurality of connected pipe sections after bending. Each pipe section is arranged in a row, and there is a spacing between adjacent pipe sections. Both end ports of the heating coil are fixedly mounted on the upper cover plate 212. The heating coil and the upper cover plate are connected by welding. The heating coil pipe sections are arranged around the inner wall of the shell body. The bending and multi-segment design of the heating coil can increase the contact area between the heating coil and the dirty oil, that is, increase the heating area for indirect heating of the dirty oil. The top view cross-section is shown in Figure 3. The indirect heating reduces the viscosity of the dirty oil and increases the fluidity, which facilitates better aggregation of different oil and water droplets and improves the separation effect of oil, water and solids.

[0042] In a specific embodiment, the transverse cross-section of the shell body 211 is square, and a number of the ultrasonic generators are evenly and symmetrically arranged on the outer wall of the shell body; in this embodiment, the shell body is a rectangular shell structure, and four flat rectangular side walls are provided on the shell body, which can facilitate the installation of the ultrasonic generator, and each side is evenly installed with a number of ultrasonic generators.

[0046] In a specific embodiment, a channel gap 14 for introducing cold air is provided between the shell body 11 and the shell body 211, and the electrical components of the ultrasonic reactor are also placed in the channel gap. Since the temperature of the ultrasonic reactor is relatively high and the ultrasonic generator continuously generates heat, cold air is introduced into the channel gap inside the shell to ensure that the electrical components therein will not be damaged due to excessive temperature, which is beneficial to ensuring the use effect and improving the service life of the device.

[0047] In a specific embodiment, the heating coil 3 is a steam heating coil, and hot steam enters from the heating coil inlet to indirectly heat the waste oil, and condensed water is discharged from the steam heating coil outlet; the steam heating coil has the advantages of rapid heating and low energy consumption, which can meet the process requirements of the device for heating and demulsifying the waste oil in the ultrasonic reactor, and also makes the device economical and energy-saving.

[0048] In a specific embodiment, a pad 5 is provided between the upper cover plate 212 and the shell body 211 and between the lower cover plate 213 and the shell body 211. The pad 5 is made of soft shock-absorbing materials such as rubber, which can effectively prevent the ultrasonic vibration of the ultrasonic reactor 2 from being transmitted to the shell 1; when the upper cover plate and the lower cover plate of the ultrasonic reactor are fixed to the shell body by bolts, a soft pad is used to play a role of seismic isolation.

[0049] In a specific embodiment, a flexible joint 6 is provided at one end of the dirty oil inlet pipe 23 extending out of the shell, and the dirty oil inlet pipe 23 is connected to the external pipeline 7 through a threaded flexible joint.
