Description

Technical Field

[0001] This invention relates to the field of mineral oil treatment technology, and more particularly to a waste mineral oil treatment device. Background Technology

[0002] Waste mineral oil is mineral oil whose original physical and chemical properties have been altered due to contamination by impurities, oxidation, and heat, rendering it unusable. It mainly originates from machinery manufacturing and processing, the power industry, and automobiles. Waste mineral oil contains various toxic and harmful substances, and its indiscriminate discharge or disposal can cause serious harm to the environment and human health. Therefore, appropriate methods are needed for its treatment. The main methods for treating waste mineral oil include physical centrifugation and chemical treatment. Physical centrifugation separates impurities from the mineral oil, followed by distillation to separate the various components from the waste mineral oil.

[0003] Existing distillation technology requires heating the entire liquid to a certain temperature before distilling it. However, only a portion of the distillable liquid can be separated using this method, resulting in low efficiency and high cost. When a component in waste mineral oil vaporizes and separates, the rising gas can easily carry other liquids to vaporize, leading to a decrease in the purity of the distilled liquid. The waste material after centrifugal separation cannot be removed simultaneously with the stratification; it can only be removed after the rotation stops, and even then, impurities in the waste material cannot be completely removed. Summary of the Invention

[0010] Preferably, the main body cylinder has an annular rotating groove in the sixth placement groove, and a limiting ring is rotatably connected to the main body cylinder in the rotating groove. The upper end of the limiting ring is fixedly connected to the lower end of the receiving shell.

Then, several first electric telescopic rods retract, causing the lower end of the protective cover to contact the upper end of the main cylinder, activating the heating element to heat and vaporize the liquid between the inner and outer flexible isolation covers. At this time, the heating element only heats the liquid between the flexible isolation covers, which can significantly reduce the mass of the heated liquid, thereby reducing energy consumption. 2. The vaporized liquid moves into the guide groove through the area between the two flexible isolation covers, and then exits through the first through hole on the inner side of the folding telescopic plate to prevent the vaporized liquid from adhering to other liquids and improve the purity of distillation. At the same time, the heating of the folding telescopic tube can increase the temperature inside the fixed tube, so that the fixed tube can maintain the vaporization temperature when the vaporized liquid passes through the flexible isolation cover, preventing the gas from liquefying prematurely and improving the efficiency of the device. After vaporization is completed, the control valve located inside the flexible isolation cover is opened. At this time, the processed mineral oil moves to the outside through the fifth placement groove, the fourth through hole, and the fifth through hole. Attached Figure Description

[0016] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] Please see Figures 1-7 A waste mineral oil treatment device includes a main cylinder 1, a sixth placement groove 51 is provided at the upper end of the main cylinder 1, and a separation mechanism 2 for separating and distilling mineral oil is provided at the upper end of the main cylinder 1.

[0018] In this embodiment, the separating mechanism 2 includes several first placement slots 21 that are equally angled and opened at the upper end of the main body cylinder 1. The main body cylinder 1 is fixedly connected to the first placement slots 21 with first electric telescopic rods 22. The telescopic ends of several first electric telescopic rods 22 are fixedly connected with protective covers 23. The lower end of the protective cover 23 is provided with a second placement slot 24.

[0019] The upper end of the protective cover 23 is provided with a plurality of guide grooves 25, which are arranged at equal angles.

[0020] Each set of first fixing bodies 29 consists of two first fixing bodies 29, which are fixedly connected by a third electric telescopic rod 216. The first fixing body 29 located on the outside is fixedly connected to the telescopic end of the second electric telescopic rod 26. Each set of two first fixing bodies 29 has a folding telescopic plate 211 fixedly connected to its side. The end face of the folding telescopic plate 211 has a first through hole 212, and the first through hole 212 of the folding telescopic plate 211 is connected to the distiller through a delivery pipe.

[0021] A fourth placement groove 214 is provided through the end face of several groups of first fixing bodies 29. A fixing tube 213 is fixedly connected to each of the several groups of first fixing bodies 29 in the fourth placement groove 214. A second fixing body 217 and a third fixing body 218 are fixedly connected to the lower end of each group of fixing tubes 213. A hollow groove 219 communicating with the inside of the fixing tube 213 is provided at the upper end of each of the several second fixing bodies 217 and the third fixing bodies 218. A second through hole 220 communicating with the hollow groove 219 is provided on the inner side of each of the several second fixing bodies 217 and the third fixing bodies 218. A heated folding telescopic tube 221 is fixedly connected to the inner side of each of the several second fixing bodies 217 and the third fixing bodies 218. A heating element 215 is fixedly connected to the side of each of the first fixing bodies 29. A flexible flexible isolation cover 28 is fixedly connected to the side of each of the several fixing tubes 213. A telescopic connecting tube 210 is connected to the upper end of the fixing tubes 213 in two adjacent first fixing bodies 29.

[0022] Specifically, several second electric telescopic rods 26 extend and retract according to the thickness of the layers, while several third electric telescopic rods 216 extend and retract, so that the inner and outer flexible isolation covers 28 cover the layered liquid to be distilled. Then, several first electric telescopic rods 22 retract, causing the lower end of the protective cover 23 to contact the upper end of the main body cylinder 1, activating the heating element 215 to heat and vaporize the liquid between the inner and outer flexible isolation covers 28. At this time, the heating element 215 only heats the liquid between the flexible isolation covers 28, which can significantly reduce the mass of the heated liquid, thereby reducing energy consumption.

[0023] In this embodiment, the main body cylinder 1 is provided with a rotating separation mechanism 5 in the sixth placement groove 51.

[0024] The rotating separation mechanism 5 includes a seventh placement groove 55 opened at the lower end of the main body cylinder 1. A motor 56 is fixedly connected to the main body cylinder 1 in the seventh placement groove 55. A receiving shell 52 is fixedly connected to the transmission shaft end of the motor 56. An eighth placement groove 57 is opened at the upper end of the receiving shell 52. A fourth electric telescopic rod 59 is fixedly connected to the receiving shell 52 in the eighth placement groove 57. A guide plate 58 is fixedly connected to the telescopic end of the fourth electric telescopic rod 59.

[0025] The main body cylinder 1 has an annular rotating groove 53 in the sixth placement groove 51. The main body cylinder 1 is rotatably connected to a limiting ring 54 in the rotating groove 53. The upper end of the limiting ring 54 is fixedly connected to the lower end of the receiving shell 52.

[0026] Specifically, motor 56 drives housing 52 to rotate, and at the same time, fourth electric telescopic rod 59 drives guide plate 58 to rise. When guide plate 58 rotates, it can drive the mineral oil inside housing 52 to rotate.

[0027] In this embodiment, a waste discharge mechanism 3 is provided at the lower end of the main body cylinder 1.

[0028] The waste discharge mechanism 3 includes a fifth placement groove 31 opened on the upper end of the receiving shell 52. A fixing plate 32 is fixedly connected in the fifth placement groove 31. A plurality of third through holes 34 are opened through the upper end of the fixing plate 32 at equal intervals. A control valve 33 is fixedly connected in the fixing plate 32 in each of the third through holes 34.

[0029] The side of the receiving shell 52 is provided with a fourth through hole 35 that communicates with the fifth placement groove 31, and the side of the main body cylinder 1 is provided with a fifth through hole 36 that communicates with the fourth through hole 35. The fifth through hole 36 is connected to the collection tank through a conveying pipe.

[0030] Specifically, the control valve 33 located inside the flexible isolation cover 28 is opened, at which point the treated mineral oil moves to the outside through the fifth placement groove 31, the fourth through hole 35 and the fifth through hole 36.

[0031] In use, the main body cylinder 1 is placed on a horizontal surface, and several first electric telescopic rods 22 are extended. These first electric telescopic rods 22 cause the lower end of the flexible isolation cover 28 to be above the liquid. Then, the motor 56 is started, which drives the receiving shell 52 to rotate. At the same time, the fourth electric telescopic rod 59 drives the guide plate 58 to rise. When the guide plate 58 rotates, it can drive the mineral oil inside the receiving shell 52 to rotate. The mineral oil is observed through the camera 4. When the mineral oil is completely separated, several second electric telescopic rods 26 first extend and retract according to the thickness of the separation. At the same time, several third electric telescopic rods 216 extend and retract, so that the inner and outer flexible isolation covers 28 cover the layered liquid to be distilled. Then, several first electric telescopic rods 22 retract, causing the lower end of the protective cover 23 to contact the upper end of the main body cylinder 1. The heating element 215 is then started to heat and vaporize the liquid between the inner and outer flexible isolation covers 28. At this time, the heating element 215 only heats the liquid between the flexible isolation covers 28, which can significantly reduce the mass of the heated liquid and thus reduce energy consumption.

[0032] When the liquid inside the inner and outer flexible isolation covers 28 is heated and vaporized, the vaporized liquid moves into the guide groove 25 through the area between the two flexible isolation covers 28, and then is discharged through the first through hole 212 on the inner side of the folding telescopic plate 211, preventing the vaporized liquid from adhering to other liquids and improving the purity of distillation. At the same time, the heating of the folding telescopic tube 221 can increase the temperature inside the fixed tube 213, so that when the vaporized liquid passes through the flexible isolation cover 28, the fixed tube 213 can maintain the vaporization temperature, prevent the gas from liquefying prematurely, and improve the efficiency of the device.

[0033] Once vaporization is complete, the control valve 33 located inside the flexible isolation cover 28 is opened, and the treated mineral oil moves to the outside through the fifth placement groove 31, the fourth through hole 35 and the fifth through hole 36.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
