[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0024] Example 1: When treating sludge containing mineral oil (hereinafter referred to as "oil sludge"), the utility model is used for circulating heating and evaporation, so that the mineral oil component and the sludge are fully separated to obtain valuable oil liquid. In addition, the petroleum content of the obtained deoiled sludge can meet the emission standards. The deoiled sludge can also be used as a filler for building bricks. The specific operation is as follows:

[0025] like Figure 1 As shown, the No. 1 motor 5 , the No. 2 motor 6 , the No. 3 motor 7 and the No. 4 motor 8 are turned on to drive the No. 1 screw shaft 13 , the No. 2 screw shaft 14 , the No. 3 screw shaft 15 and the No. 4 screw shaft 16 respectively.

[0026] like Figure 1 、 Figure 2 As shown, the feed pipe sealing cover 22 is opened, a certain amount of the oil sludge is added to the feed pipe 17, and then the feed pipe sealing cover 22 is closed. After the oil sludge falls into the No. 1 delivery pipe 9, it is dispersed into the No. 1 delivery pipe 9, the No. 2 delivery pipe 10, the No. 3 delivery pipe 11, and the No. 4 delivery pipe 12 under the action of each spiral shaft to perform a cyclic motion.

[0027] Further, if Figure 1 As shown, the second heater 19, the third heater 20, and the fourth heater 21 are turned on to heat the oil sludge circulating in the conveying pipe.

[0028] Further, if Figure 1 、 Figure 2 As shown, by observing the thermometer 27, when the temperature reaches 100 degrees, the water contained in the sludge turns into water vapor and begins to evaporate, and is discharged to the outside through the steam discharge pipe 18, condensed and collected for processing.

[0029] Further, if Figure 1 、 Figure 2As shown, the atmospheric distillation range of common mineral oil is 120 degrees to 450 degrees. As the temperature of the oil sludge gradually increases, the mineral oil contained in the oil sludge gradually turns into steam and is discharged outward through the steam discharge pipe 18 to be condensed and collected for processing and utilization.

[0030] Further, if Figure 1 、 Figure 2 As shown, observing the thermometer 27, when the temperature reaches 450 degrees, the mineral oil components contained in the sludge are basically evaporated. To ensure that the mineral oil components are basically completely evaporated, the heating is continued to 480 degrees and then the No. 2 heater 19, the No. 3 heater 20, and the No. 4 heater 21 are turned off and the heating is stopped. At this time, the sludge has been converted into deoiled sludge with an oil content of less than 0.3% and can be discharged or utilized.

[0031] Further, if Figure 1 、 Figure 2 As shown, after the slag discharge pipe valve 24 is opened, the rotation direction of the No. 1 motor 5 is changed to make the No. 1 screw shaft 13 perform reverse motion, gradually driving the deoiled sludge in each conveying pipe to move toward the slag discharge pipe 23. After the deoiled sludge has all fallen into the slag collecting tank 25, the slag discharge pipe valve 24 is closed.

[0032] Further, if Figure 1 、 Figure 2 As shown, after the de-oiled sludge is cooled to a suitable temperature, the sealing cover 26 of the slag collecting tank is opened to discharge the de-oiled sludge. Thus, the purpose of separating the mineral oil component contained in the oil sludge is achieved.

[0033] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
