Description

Technical Field

[0001] This application relates to the field of end-of-life motor vehicle technology, and in particular to a waste liquid extraction and discharge device for end-of-life motor vehicles. Background Technology

[0002] With the sustained, stable and healthy development of the economy, the development of the automobile industry and the acceleration of automobile replacement, the number of scrapped cars is increasing year by year, and enterprises involved in scrapped car dismantling are springing up all over the country.

[0003] During the disposal of scrapped vehicles, liquids, including various oils and water, need to be extracted from the vehicles before the chassis is processed. The extracted water and oil need to be filtered and separated. On the one hand, they can be reused through refining and other technologies. On the other hand, wastewater can be discharged only after it meets the discharge standards through filtration and other means, so as to achieve energy reuse and environmental protection goals.

[0004] A utility model patent published in Chinese patent document, authorization announcement number CN214787839U, discloses a "wastewater and waste liquid extraction device for scrapped vehicles," specifically including a base, a lifting plate, a filter separation box, and a water pump. The base has a column, and the top of the column has a top plate. A first motor is mounted on the top plate, and a lead screw is connected downwards to the first motor. The lead screw is connected to both the top plate and the base via bearings. A threaded sleeve and a sliding sleeve are respectively provided on the lead screw and the column. The threaded sleeve and the sliding sleeve are both located at the left end of the lifting plate, and the filter separation box is located on the lifting plate. A support block is located at the right end of the lifting plate, and the water pump is located on the support block. An inlet pipe is located at the upper end of the filter separation box, and the water pump is located on the inlet pipe. This wastewater and waste liquid extraction device for scrapped vehicles can extract liquids from scrapped vehicles and also perform filtration and separation, preparing for subsequent energy reuse and environmental protection.

[0005] However, the aforementioned technologies generally involve an oil-water separation process when recycling waste fluid from dismantling motor vehicles. The water layer obtained after oil-water separation can be easily discharged, but the separated grease layer is prone to solidification after the separation period, which can block the discharge pipe and make it difficult to discharge the grease layer. Therefore, a waste fluid recycling device for dismantling motor vehicles is proposed.

[0006] The information disclosed in the background section above is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0031] In order to achieve the above objectives,

[0032] Reference Figures 1-2 This application provides a waste liquid extraction device for scrapped motor vehicles, including a base 1, a separation component 2, and a collection component 3.

[0033] In this embodiment, the separation component 2 is disposed on the base 1, the base 1 is used to place the separation component 2, the separation component 2 is used to filter and separate the waste liquid collected from the scrapped motor vehicle, and the collection component 3 is disposed on the separation component 2 to collect the waste liquid from the scrapped motor vehicle.

[0034] The separation component 2 includes a separation box 21, a magnetic adsorption device 22, a first filter screen 23, a stirring device 26, and an oil-water separation plate 27.

[0035] The magnetic adsorption device 22, the first filter screen 23, the stirring device 26, and the oil-water separation plate 27 are all installed in the separation tank 21. The magnetic adsorption device 22 first recovers metal resources such as scrap iron from the waste liquid of the scrapped motor vehicle. The first filter screen 23 mainly removes large impurities and particulate matter from the waste liquid. The oil-water separation plate 27 mainly separates oil and water from the waste liquid of the scrapped motor vehicle. The stirring device 26 stirs the separated oil to prevent it from solidifying.

[0036] Specifically, the top of the separation chamber 21 is open. The magnetic adsorption device 22 and the first filter screen 23 are arranged sequentially from top to bottom on the top of the separation chamber 21. The oil-water separation plate 27 is horizontally arranged and divides the interior of the separation chamber 21 into a first chamber 213 and a second chamber 214. The first chamber 213 is located above the second chamber 214. The stirring device 26 is arranged inside the first chamber 213.

[0037] Meanwhile, the outside of the separation box 21 is provided with a first liquid outlet pipe 211 that connects to the first chamber 213 and a second liquid outlet pipe 212 that connects to the second chamber 214. The other end of the first liquid outlet pipe 211 is connected to the first recycling box 215 for collecting the oil separated from the waste liquid of the scrapped motor vehicle, and the other end of the second liquid outlet pipe 212 is connected to the second recycling box 216 for collecting the water separated from the waste liquid of the scrapped motor vehicle.

[0038] The first liquid outlet pipe 211 is located above and tangent to the oil-water separation plate 27, which facilitates the separate discharge of the grease layer. The second liquid outlet pipe 212 is located in the separation box 21.

[0039] The oil-water separation plate 27 consists of a series of plates with specific structures that are repeatedly stacked to separate oil and water based on their physical properties (such as density difference and immiscibility). When a high-concentration oil-water mixture flows through these plates, it will be fully distributed horizontally and vertically within the plates, thus achieving effective oil-water separation.

[0040] Optionally, the first filter screen 23 in this embodiment can be a metal mesh or sieve with a large aperture as the filter medium to ensure that the waste liquid can pass through smoothly while effectively intercepting large impurities. The bottom of the base 1 can be equipped with casters to allow the pumping device to move, and a push rod is generally provided to push the pumping device.

[0041] Considering that waste liquid from scrapped motor vehicles may contain flammable and explosive substances, the device should adopt an explosion-proof design, such as using an explosion-proof motor (262) and explosion-proof switches. This ensures that no explosion will occur due to sparks or high temperatures during the pumping and filtration process.

[0042] As an optional implementation, the separation component 2 of this embodiment further includes a second filter screen 24, which is disposed below the first filter screen 23.

[0043] By setting up a second filter screen 24, fine particulate matter and suspended solids in the waste liquid can be further removed. The second filter screen 24 can use multi-layer fiber filter cloth or ceramic filter element as the filter medium, which has high filtration accuracy and strong interception capability.

[0044] Meanwhile, the second chamber 214 is filled with a filter layer 25. The water separated by the oil-water separator 27 is adsorbed and purified through the filter layer 25 to ensure that the discharged waste liquid is clear and transparent.

[0045] Optionally, the filter layer 25 in this embodiment can use a liquid sludge adsorption plate or an activated carbon filter element as the filter medium, which has strong adsorption capacity and filtration effect.

[0046] As an optional implementation, the magnetic adsorption device 22 of this embodiment includes an adsorption box 221 and a magnetic block 222 disposed on the top inner side of the adsorption box 221. The two ends of the adsorption box 221 are respectively connected to the collection component 3 and the separation box 21.

[0047] By setting a magnetic block 222 on the top side inside the adsorption box 221, the waste iron and other metal resources in the waste liquid are recycled and reused, thereby improving the resource utilization rate.

[0048] Optionally, the stirring device 26 in this embodiment includes a motor 262 and a stirring shaft 261 that is drivenly connected to the motor 262. The motor 262 is disposed in the separation box 21, and the stirring shaft 261 is disposed in the first chamber 213.

[0049] Furthermore, in this embodiment, the separation box 21, magnetic adsorption device 22, first filter screen 23, second filter screen 24, filter layer 25, stirring device 26 and oil-water separation plate 27 can all be detachably connected to the separation box 21 by bolts or snap-fit ​​structures, and the first filter screen 23 and the second filter screen 24 can be tilted relative to the separation box 21.

[0050] As an optional implementation, the collection component 3 of this embodiment includes a water pump 32 and a water pump pipe 31 connected to the inlet of the water pump 32, and the outlet of the water pump 32 is connected to the separation component 2. The water pump pipe 31 is typically a flexible hose.

[0051] Furthermore, in this embodiment, the outer wall of the separation box 21 is provided with a buckle 33 for fixing the water pumping pipe 31.

[0052] As an optional implementation, the base 1 of this embodiment is provided with a lifting device on top, and the separation box 21 is disposed on top of the lifting device to facilitate the adjustment of the height of the separation box 21 and the collection component 3.

[0053] The lifting device includes at least three spaced-apart electric lifting rods 11. The above are merely preferred embodiments of this utility model and are not intended to limit the scope of the utility model. It is obvious to those skilled in the art that this application is not limited to the details of the above exemplary embodiments, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application.
