Abstract
Description
Technical Field
[0001] This application relates to the field of end-of-life vehicle recycling technology, and in particular to a waste oil recycling and processing device for end-of-life vehicles. Background Technology
[0002] Motor vehicles that have reached the national scrapping standard, or those that have not reached the national scrapping standard but whose engines or chassis are severely damaged and which do not meet the national motor vehicle operation safety technical conditions or the national motor vehicle pollutant emission standards, are called scrapped vehicles. Some scrapped vehicles were still in use before they were scrapped, so there is often a certain amount of fuel left in the fuel tank.
[0003] Currently, the main methods for removing residual fuel from fuel tanks are direct pouring or extraction via pipeline, followed by further processing of the removed fuel. These two methods are widely used due to their simplicity.
[0004] However, neither of the above methods can completely clean the oil film remaining on the inner wall of the fuel tank. Incomplete fuel recovery not only causes significant environmental pollution, but also causes the fuel to evaporate into the air during subsequent operations, which can harm the health of operators. Furthermore, directly discarding the residual fuel can easily lead to energy waste, which does not meet the social requirements of energy conservation and environmental protection. Summary of the Invention

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.
[0028] The applicant found that existing methods for recycling and disposing of waste oil from scrapped vehicles are ineffective at removing the residual oil film in the fuel tank, resulting in the waste of this fuel. Furthermore, the fuel evaporates into the air during subsequent processing, causing significant environmental pollution and posing a threat to the health of operators.
[0029] To address the aforementioned issues, this application provides a technical solution that uses hot gas to drive the brush head to rotate. The brush head removes the oil film, while the hot gas vaporizes any remaining fuel after brush head treatment, effectively reducing waste oil residue.
[0030] This application discloses a waste oil recycling and processing device for scrapped automobiles. (Reference) Figure 1 The waste oil recycling and processing device for scrapped vehicles includes an oil storage tank 1, an oil extraction assembly 2, a brush head 4, and a gas conveying assembly 3.
[0031] For details, please refer to Figure 2 The oil storage tank 1 is a metal tank, and a filter assembly is installed inside the oil storage tank 1. The filter assembly divides the oil storage tank 1 into a separation chamber 106 and an oil storage chamber 107. The filter assembly is located in the separation chamber and has three layers, from top to bottom: an impurity collection box 101, a wastewater collection box 103, and an activated carbon layer 105.
[0032] The impurity collection box 101 is snapped into the inner wall of the oil storage tank 1. A metal filter screen 102 is fixedly connected to the bottom of the impurity collection box 101. The metal filter screen 102 is used to filter solid impurities such as metal shavings in the waste oil. The pore size of the metal filter screen 102 is 0.5mm.
[0033] Wastewater collection box 103 is snapped into the inner wall of oil storage tank 1. An oil-water separation membrane 104 is fixedly connected to the bottom of wastewater collection box 103 for separating water from waste oil. The oil-water separation membrane 104 is a water separation membrane made of hydrophilic and oleophobic material with an oil-water separation efficiency of ≥95%.
[0034] The activated carbon layer 105 is snapped into the inner wall of the oil storage tank 1 to adsorb impurity particles. After passing through three layers of filtration, the waste oil falls to the bottom of the oil storage tank 1, solid impurities remain in the impurity collection box 101, and water remains in the wastewater collection box 103.
[0035] The top of the oil storage tank 1 is a removable cover plate 111. A hydraulic lifting column 108 is fixedly connected to the side wall of the oil storage tank 1. The other end of the hydraulic lifting column 108 is fixedly connected to the base 112. The stroke of the hydraulic lifting column 108 is 300-800mm, which is used to adjust the height of the oil storage tank 1 according to the different heights of the oil tank. The base 112 is equipped with casters 113 and locking parts 114. The casters 113 drive the entire processing device to move, and the locking parts 114 are used to fix the casters 113 to prevent the processing device from moving during use. An electrostatic grounding terminal 109 is provided on the side wall of the oil storage tank 1. The electrostatic grounding terminal 109 passes through the base plate and the other end is connected to the ground. The grounding resistance of the grounding terminal is ≤10Ω. A valve 110 is also provided near the bottom of the side wall of the oil storage tank 1. The valve 110 is used to remove the filtered waste oil from the oil storage tank 1. The side wall of the oil storage tank 1 is also provided with an observation window 115 for observing the situation inside the oil storage tank 1, facilitating timely cleaning of the impurity collection box 101 and the wastewater collection box 103, as well as removing the filtered waste oil.
[0036] The oil extraction assembly 2 includes an oil suction pipe 202 and an oil pump 201. The oil pump 201 is fixed to the top of the oil storage tank 1. The oil pump 201 has an inlet end and an outlet end. The inlet end of the oil pump 201 is fixedly connected to the oil suction pipe 202, and the outlet end of the oil pump 201 is equipped with a condenser 203. The condenser 203 is a common natural convection condenser 203 used to condense oil vapor. The other end of the oil suction pipe 202 is connected to a brush head 4, which has an oil suction hole. The oil extraction assembly 2 is used to draw waste oil from the oil tank into the oil storage tank 1 through the oil suction pipe 202 and the oil pump 201, and obtain clean waste oil after filtration by the filter assembly.
[0037] A controller 5 is installed on the oil suction pipe 202. The controller 5 controls the oil suction assembly 2 and the gas delivery assembly 3. A telescopic pipe 204 is fixedly connected to the controller 5. The oil suction pipe 202 is located inside the telescopic pipe 204, and the other end of the telescopic pipe 204 is rotatably connected to the brush head 4. A sealing ring 501 is installed at the end of the telescopic pipe 204 of the controller 5. During use, the sealing ring 501 seals the oil tank and the controller 5, preventing waste oil in the oil tank from entering the air. The controller 5 is also equipped with an anti-static wrist strap interface 502. The anti-static wrist strap is a common type available on the market. When using this device, the operator wears the anti-static wrist strap, which connects to the anti-static wrist strap interface 502 on the controller 5 to prevent static electricity generation.
[0038] The gas delivery assembly 3 includes a compressor 301, a heating element 303, and an air inlet pipe 302. The compressor 301 is located at the top of the oil storage tank 1. The air inlet pipe 302 is fixedly connected to the compressor 301. The heating element 303 is located inside the air inlet pipe 302 and is used to heat the air input to the compressor 301. The heating element 303 can be a heating resistor. The air inlet pipe 302 is connected to the controller 5 and extends within the telescopic tube 204 to the brush head 4, where it is fixedly connected. After the controller 5 starts the gas delivery assembly 3, the compressor 301 compresses the air and sends it into the air inlet pipe 302. After being heated by the heating element 303, it becomes hot air, which is then discharged from the brush head 4, vaporizing the residual oil film. Simultaneously, as the gas is discharged, the brush head 4 is driven to rotate by the gas, brushing away oil film residue from the inner wall of the oil tank.
[0039] For details, please refer to Figure 3 The brush head 4 is rotatably connected to the telescopic tube 204. An inclined air hole 401 is provided on the side wall of the brush head 4 to discharge the gas delivered by the gas delivery assembly 3. The inclined air hole 401 can also generate thrust, driving the brush head 4 to rotate while the gas is discharged. An oil suction hole is provided at the end of the brush head 4. This oil suction hole is used by the oil extraction assembly 2 to draw waste oil and oil vapor into the oil storage tank 1 through the oil suction pipe 202.
[0040] The principle of the waste oil recycling and treatment device for scrapped vehicles in this embodiment is as follows: The compressor 301 inputs air into the intake pipe 302, which is heated by the heating element 303 to form hot air. The hot air is discharged from the air hole 401 on the brush head 4, which drives the brush head 4 to rotate. The rotation of the brush head 4 removes the oil film. The hot air vaporizes the oil film, reducing the amount of waste oil residue on the inner wall of the oil tank. The waste oil and oil vapor are drawn into the suction pipe 202 through the oil suction port 402 on the brush head 4 under the action of the oil pump 201, and finally enter the oil storage tank 1. After being condensed by the condenser 203, the oil vapor becomes liquid. After being filtered by the filter assembly, it enters the oil storage chamber 107 and is finally discharged through the valve 110 at the bottom of the oil storage tank 1.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
