[0002] The comprehensive utilization of waste mineral oil is of great significance for alleviating the shortage of resources in my country, solving the bottleneck problem of oil supply falling short of demand, improving the utilization rate of existing resources, and protecting the ecological environment. Waste mineral oil needs to be decolorized during the processing. Generally, decolorization is achieved by mixing and stirring waste mineral oil and decolorizing agent in a decolorization tank.

[0003] An existing mixed oil decolorization tank (publication number: CN221964536U) has at least the following drawbacks: the device sets two stirring blades inside the decolorization tank and makes the two stirring blades rotate relative to each other, causing the oil in the decolorization tank to be flushed from top to bottom. This causes the decolorizing agent in the upper layer of the oil to be obstructed by the flow of the lower layer of oil, making it difficult for the decolorizing agent to flow to the lower layer of oil in a short time, thus affecting the decolorization efficiency of waste mineral oil. Therefore, this utility model is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste mineral oil decolorization device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste mineral oil decolorization device includes a decolorization tank. Inside the decolorization tank is a stirring assembly for agitating the waste mineral oil. The stirring assembly includes a circulation cylinder fixed to the bottom surface inside the decolorization tank.

[0007] As a further embodiment of this utility model, a gear ring is fixed inside the rotating seat near the bottom surface, and a driven gear is rotatably connected to the bottom surface of the rotating seat. The driven gear meshes with the gear ring. A driving gear is fixed to the outer wall of the driving rod, and the driving gear meshes with the driven gear.

[0022] like Figures 1-4 As shown, a waste mineral oil decolorization device includes a decolorization tank 1. The decolorization tank 1 is equipped with a stirring assembly for stirring the waste mineral oil. The stirring assembly includes a circulation cylinder 2 fixed to the bottom surface of the decolorization tank 1. A top frame 201 is provided above the circulation cylinder 2. The top frame 201 is fixed to the top surface of the decolorization tank 1. A rotating seat 202 is rotatably connected to the outer wall of the top frame 201. Several stirring blades 203 are fixed to the outer wall of the rotating seat 202. A drive rod 204 is rotatably connected to the top surface of the decolorization tank 1. The top frame 201 and the rotating seat 202 are both rotatably connected to the outer wall of the drive rod 204. Several circulating impellers 205 are fixed to the outer wall of the drive rod 204. The circulating impellers 205 are located inside the circulation cylinder 2.

[0023] like Figures 2-4As shown, in this embodiment, a gear ring 206 is fixed inside the rotating seat 202 near the bottom surface. A driven gear 207 is rotatably connected to the bottom surface of the rotating seat 202, and the driven gear 207 meshes with the gear ring 206. A drive gear 208 is fixed to the outer wall of the drive rod 204, and the drive gear 208 meshes with the driven gear 207. The diameters of the drive gear 208 and the driven gear 207 are equal, and the gear ratio between the drive gear 208 and the gear ring 206 is 10 to 12. A reduction motor 209 is fixed to the top surface of the decolorizing tank 1, and the output shaft of the reduction motor 209 is fixed to the top end of the drive rod 204. Waste mineral oil that has been pickled and filtered and composite metal decolorizing agent are added to the interior of the decolorizing tank 1 through two feeding pipes 3 according to a predetermined ratio. Then, the reduction motor 209 is started to drive the drive rod 204 to rotate. At this time, the circulating impeller 205 and the drive gear 208 rotate rapidly. Under the meshing action of the drive gear 208 and the driven gear 207, the driven gear 207 rotates. Under the meshing action of the driven gear 207 and the gear ring 206, the gear ring 206, the rotating seat 202 and the stirring blade 203 rotate synchronously. Since the gear ratio between the drive gear 208 and the gear ring 206 is 10 to 12, the circulating impeller 205 rotates rapidly while the stirring blade 203 rotates slowly, reducing the load on the reduction motor 209. At this time, the rapidly rotating circulating impeller 205, together with the circulating cylinder 2, quickly transports the bottom layer of oil to the upper layer, so that the oil inside the decolorizing tank 1 continuously circulates up and down. With the stirring of the stirring blade 203, the waste mineral oil and the decolorizing agent are fully mixed, increasing the decolorization effect on the waste mineral oil.

[0024] like Figures 2-4 As shown, in this embodiment, several circulating impellers 205 are arranged in a linear array inside the circulating cylinder 2, and several stirring blades 203 are arranged in a circular array on the outer wall of the rotating seat 202. Several crossbars are also arranged in a linear array on each stirring blade 203. By arranging the circulating impellers 205 evenly distributed inside the circulating cylinder 2, the stable delivery of oil is ensured. The mixing range of the stirring blades 203 is ensured by arranging several crossbars in a linear array on each stirring blade 203.

[0025] like Figures 2-4 As shown in this embodiment, the top surface of the decolorizing tank 1 is connected to and fixed with two feeding pipes 3, and the bottom surface of the decolorizing tank 1 is connected to and fixed with an electromagnetic discharge valve 301. The decolorizing agent and waste mineral oil can be added to the decolorizing tank 1 through the two feeding pipes 3 respectively, and the waste mineral oil after decolorization can be discharged by opening the electromagnetic discharge valve 301.

[0026] like Figures 2-4As shown in this embodiment, the decolorizing tank 1 has several heating plates 4 arranged in a circular array inside. By setting the heating plates 4, the waste mineral oil can be heated during the decolorization process, ensuring that the waste mineral oil is maintained at the optimal decolorization temperature and increasing the decolorization effect.

[0027] like Figures 2-4 As shown, in this embodiment, a thermometer 5 is fixed on the top surface of the decolorizing tank 1, and the detection end of the thermometer 5 extends into the interior of the decolorizing tank 1. A PLC controller is fixed on one side of the decolorizing tank 1. The geared motor 209, the electromagnetic discharge valve 301, the heating plate 4, and the thermometer 5 are all electrically connected to the PLC controller. The temperature of the waste mineral oil is monitored in real time by setting the thermometer 5 and the signal is transmitted to the PLC controller. The PLC controller then controls the heating plate 4 to open and close for temperature control.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, when it is necessary to decolorize waste mineral oil, the acid-washed and filtered waste mineral oil and the composite metal decolorizing agent are added into the decolorization tank 1 through two feeding pipes 3 according to a predetermined ratio. Then, the reduction motor 209 is started to drive the drive rod 204 to rotate. At this time, the circulating impeller 205 and the drive gear 208 rotate rapidly. Under the meshing action of the drive gear 208 and the driven gear 207, the driven gear 207 rotates. Under the meshing action of the driven gear 207 and the gear ring 206, the gear ring 206, the rotating seat 202 and the stirring blade 203 rotate synchronously. Since the gear ratio between the drive gear 208 and the gear ring 206 is 10 to 12, the circulating impeller 205... The rotating impeller 205 rotates rapidly while the stirring blade 203 rotates slowly, reducing the load on the geared motor 209. At this time, the rapidly rotating circulating impeller 205, together with the circulating cylinder 2, quickly transports the bottom layer of oil to the upper layer, so that the oil inside the decolorizing tank 1 continuously circulates up and down. Combined with the stirring of the stirring blade 203, the waste mineral oil and the decolorizing agent are fully mixed, increasing the decolorization effect of the waste mineral oil. Then, the waste mineral oil after decolorization can be discharged by opening the electromagnetic discharge valve 301. The heating plate 4 can be set to heat the waste mineral oil during decolorization to ensure that the waste mineral oil is maintained at the optimal decolorization temperature and increase the decolorization effect. The temperature of the waste mineral oil is monitored in real time by the thermometer 5 and the signal is sent to the PLC controller. The PLC controller then controls the opening and closing of the heating plate 4 for temperature control.
