[0013] The present invention also discloses a method for using a regenerated mixed hydrocarbon clean diesel production device, which mainly comprises the following steps: Step 1: The hazardous waste mineral oil to be treated is transported to the impurity filter cylinder through the oil pump 1. The output end of the motor rotates to drive the bevel gear 1 to rotate. The rotation of the bevel gear 1 drives the bevel gear 2 to rotate. The rotation of the bevel gear 2 drives the driving pipe to rotate. The rotation of the driving pipe drives the impurity filter cylinder to rotate. The impurity filter cylinder rotates to leave larger impurities in the impurity filter cylinder. After the mineral oil is filtered by the filter bag 1, it is thrown out through the centrifugal hole and enters the bottom end of the stirring chamber. Step 2: After the freezing tube is started, the mineral oil in the stirring chamber is cooled and frozen. The rotation of the impurity filter cylinder drives the connecting piece to rotate, the rotation of the connecting piece drives the driving roller to rotate, the driving roller drives the stirring rod to rotate, and the stirring rod stirs the mineral oil. During the cooling and freezing process, some impurities will crystallize together with water, further improving the purity of the mineral oil. The cooling and freezing process makes the water exist in the form of crystals, and the difference in physical properties with the mineral oil is more obvious; Step 3: After the water crystallizes, the output end of the cylinder moves upward to drive the blocking block to move upward. The blocking block moves upward to open the filter port and start the oil pump 2. The mineral oil enters the output pipe 1 and the output pipe 2 through the filter bag 2 and flows into the treatment tank 2. The crystals remain in the stirring chamber. When the mineral oil passes through the separation plate 1 and the separation plate 2, the metal particles in the mineral oil are adsorbed by the strip magnetic block 1 and the strip magnetic block 2, and then flow into the treatment tank 2. Start the air compressor, connect the air compressor to an external inert gas source, open the electronic valve, and use the microbubbles generated by the bubble disk to drive the suspended matter in the mineral oil to the top of the mineral oil. After the treatment is completed, open the collection valve to collect the treated mineral oil.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The hazardous waste mineral oil pretreatment mechanism is set up, through the rotation of the impurity filter cylinder and the filtration of the filter bag, it can effectively remove the larger impurities in the hazardous waste mineral oil. Compared with static filtration, this dynamic filtration method can more efficiently process a large amount of mineral oil while ensuring the removal effect of impurities.

[0015] (2) The hazardous waste mineral oil pretreatment mechanism is set up. The mineral oil is stirred by a stirring rod during the stirring process. Combined with the cooling and freezing treatment, some impurities are crystallized together with water, which further improves the purity of the mineral oil. It can not only remove physical impurities, but also effectively remove some tiny impurities dissolved or dispersed in the mineral oil.

[0016] (3) The setting up of hazardous waste mineral oil pretreatment mechanism, the cooling and freezing treatment makes the water exist in the form of crystals, and the difference in physical properties between the water and mineral oil is more obvious, which is conducive to the subsequent separation operation. Through the difference in physical properties, the water and mineral oil can be separated more easily, thus improving the treatment efficiency.

[0017] (4) By setting the separation plate 1 and the separation plate 2, as well as the strip magnetic block 1 and the strip magnetic block 2, the metal particles in the mineral oil can be effectively adsorbed and removed, which is crucial to improving the quality of the regenerated mixed hydrocarbon clean diesel.

[0018] (5) Use the microbubbles generated by the air compressor to drive the suspended matter in the mineral oil to the top of the mineral oil, making it easier to remove it later. This method can remove some tiny suspended matter that is difficult to remove by physical filtration and chemical treatment. BRIEF DESCRIPTION OF THE DRAWINGS
