Description

Technical Field

[0001] This utility model relates to the field of dehydration devices, and in particular to a waste oil dehydration device. Background Technology

[0002] The raw materials for bio-oilseeds are mostly waste oils such as acidified oil and gutter oil. Due to the variety of raw materials and their complex sources, the raw materials contain a large amount of wastewater, so they need to be dehydrated in advance.

[0003] Existing dehydration devices generally use static separation to separate oil and water after they separate into layers, or heating separation to rapidly evaporate water for dehydration. However, both methods are not very efficient, and the water dissolved inside the oil is difficult to completely separate after processing. It will re-precipitate after a period of time, resulting in incomplete dehydration. Utility Model Content

[0004] The purpose of this invention is to provide a waste oil dehydration device. During dehydration, the main motor, heating plate, and vacuum pump are started to heat and stir the internal oil and reduce the internal air pressure, so that the water inside the oil can be fully separated and extracted, thereby improving the dehydration efficiency and degree. After dehydration is completed, the oil can enter the capillary copper tube, and the cooling fan and heat conduction plate are used to dissipate heat from the internal oil, so that it can be discharged more quickly and convenient for subsequent use.

[0005] To achieve the above objectives, a waste oil dehydration device is provided, comprising: a dehydration tank; a heating plate fixedly connected to the inner circumference of the dehydration tank; an inner liner fixedly connected to the inner circumference of the heating plate; a temperature sensor fixedly connected to the inner circumference of the inner liner; a pressure sensor fixedly connected to the inner top surface of the dehydration tank; a main shaft rotatably connected to the inner top surface of the dehydration tank; and stirring blades fixedly connected to the circumference of the main shaft. The stirring blades are multiple in number and evenly distributed on the main shaft. The top of the water tank is fixedly connected to a main motor, a vacuum pump, and a feed pipe. The bottom of the dehydration tank is fixedly connected to a bottom box. An air inlet is provided on the front side wall of the bottom box. A cooling fan is fixedly connected to the front side wall inside the bottom box, and the cooling fan is located behind the air inlet. A filter screen is fixedly connected to the rear side wall of the bottom box. A heat-conducting plate is fixedly connected inside the bottom box. A capillary copper tube is provided inside the bottom box. The capillary copper tube is "S"-shaped, and an upper valve and a lower valve are fixedly connected to the capillary copper tube.

[0006] According to the waste oil dehydration device, the bottom output end of the main motor is fixedly connected to the main shaft. When the main motor is started, the main shaft rotates and drives the stirring blades to fully stir the internal oil.

[0007] According to the waste oil dehydration device described above, multiple heat-conducting plates are evenly and parallelly arranged between the cooling fan and the filter screen. When the cooling fan is activated, the heat on the heat-conducting plates inside the base box can be blown out of the base box from one side of the filter screen.

[0008] According to the waste oil dehydration device described above, the capillary copper tube evenly penetrates the heat-conducting fins, the top of the capillary copper tube penetrates the dehydration tank, and the bottom of the capillary copper tube penetrates the bottom box. The grease inside the dehydration tank can enter the capillary copper tube for heat dissipation before being discharged.

[0009] According to the waste oil dehydration device, the upper valve is located inside the bottom box, and the lower valve is located below the bottom box.

[0010] According to the waste oil dehydration device, the feed pipe and the vacuum pump are located on the left and right sides of the main motor, respectively.

[0011] According to the waste oil dehydration device, the bottom of the dehydration tank is fixedly connected to a support column, and the number of the support columns is three, which are evenly distributed at the bottom of the dehydration tank.

[0012] The above-mentioned solution has the following beneficial effects:

[0013] 1. By setting up a dehydration tank, heating plate, inner liner, air pressure sensor, temperature sensor, main shaft, stirring blade, main motor, vacuum pump and feed pipe, the main motor, heating plate and vacuum pump are started during dehydration to heat and stir the internal oil and reduce the internal air pressure, so that the water inside the oil can be fully separated and extracted, thereby improving the dehydration efficiency and degree of dehydration.

[0014] 2. By setting up a base box, air inlet, cooling fan, heat conduction plate, capillary copper tube, filter screen, upper valve and lower valve, after dehydration is completed, the grease can enter the capillary copper tube, and the cooling fan and heat conduction plate can dissipate heat from the internal grease, so that it can be discharged more quickly, which is convenient for subsequent use.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4This utility model discloses a waste oil dehydration device, comprising: a dehydration tank 1; a heating plate 2 fixedly connected to the inner circumference of the dehydration tank 1; an inner liner 3 fixedly connected to the inner circumference of the heating plate 2; a temperature sensor 5 fixedly connected to the inner circumference of the inner liner 3 for monitoring the oil temperature; a pressure sensor 4 fixedly connected to the inner top surface of the dehydration tank 1 for monitoring the internal pressure; a main shaft 6 rotatably connected to the inner top surface of the dehydration tank 1; stirring blades 7 fixedly connected to the circumference of the main shaft 6; and multiple stirring blades 7 evenly distributed on the main shaft 6. The top is fixedly connected to a main motor 8, a vacuum pump 9, and a feed pipe 10. The feed pipe 10 and the vacuum pump 9 are located on the left and right sides of the main motor 8, respectively. When the vacuum pump 9 is started, the internal air pressure decreases, thereby lowering the water vaporization temperature, allowing the water to precipitate, evaporate, and be extracted more quickly. The bottom output end of the main motor 8 is fixedly connected to the main shaft 6. When the main motor 8 is started, the main shaft 6 rotates, causing the stirring blades 7 to fully stir the internal oil, separating the water mixed inside the oil. The bottom of the dehydration tank 1 is fixedly connected to a bottom box 11, and the front side wall of the bottom box 11 is equipped with... An air inlet 12 is provided. A cooling fan 13 is fixedly connected to the front wall of the inner side of the base box 11, located behind the air inlet 12. A filter 16 is fixedly connected to the rear wall of the base box 11. Multiple heat-conducting plates 14 are fixedly connected inside the base box 11 and are evenly and parallelly arranged between the cooling fan 13 and the filter 16. A capillary copper tube 15 is provided inside the base box 11. The capillary copper tube 15 is "S"-shaped and is fixedly connected to an upper valve 17 and a lower valve 18. The capillary copper tube 15 evenly penetrates the heat-conducting plates 14, conducting... The heat sink 14 can transfer the heat of the grease in the capillary copper tube 15 to the outside. The top of the capillary copper tube 15 passes through the dehydration tank 1 and the bottom of the capillary copper tube 15 passes through the bottom box 11. The upper valve 17 is located inside the bottom box 11 and the lower valve 18 is located below the bottom box 11. After dehydration is completed, the cooling fan 13 can be turned on to inject outside air into the bottom box 11 and the upper valve 17 can be opened to allow the grease to enter the capillary copper tube 15 and transfer the heat to the heat-conducting plate 14. The air flowing through it continuously passes through the heat-conducting plate 14 and is discharged from the filter screen 16 side, thereby reducing the temperature of the grease and facilitating subsequent use.

[0025] The bottom of the dehydration tank 1 is fixedly connected to a support column 19. There are three support columns 19, which are evenly distributed at the bottom of the dehydration tank 1.

[0026] Working principle: Waste oil is fed into the dehydration tank 1 through the feed pipe 10. Then, the heating plate 2 is activated to heat the inner tank 3, raising the temperature of the oil inside. At the same time, the vacuum pump 9 is activated to lower the air pressure inside the inner tank 3, thereby reducing the vaporization temperature of the water. This allows the water to be extracted, evaporated, and removed more quickly. The main motor 8 is activated to rotate the main shaft 6, which in turn causes the stirring blades 7 to thoroughly stir the oil inside, separating the water mixed inside the oil. The water then vaporizes upon heating, thus completing the dehydration process efficiently. After dehydration is complete, the cooling fan 13 is activated and the upper valve 17 is opened, allowing the oil to enter the capillary copper tube 15 and transfer heat to the heat-conducting plate 14. The air flowing through the heat-conducting plate 14 is continuously discharged from the filter screen 16, thereby lowering the oil temperature. The lower valve 18 is opened to discharge the oil for subsequent use.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
