Description

Technical Field

[0001] This utility model relates to the field of waste engine oil recycling technology, specifically, to a primary impurity removal device for waste engine oil. Background Technology

[0002] Engine oil is an essential lubricant for the normal operation of a car engine. After a car has traveled a certain distance, incomplete combustion of fuel produces carbon particles, and wear and tear on engine parts produces metal shavings. These shavings and sludge accumulate in the engine oil, drastically reducing its lubricating properties, accelerating wear, and affecting the engine's normal operation. Therefore, it is necessary to change the engine oil. In line with the concept of sustainable development, waste engine oil is recycled. During the recycling process, impurities contained within the waste oil are first removed.

[0003] For example, a waste oil collection device for automobile repair disclosed in patent CN218573929U uses a magnetic rod in conjunction with two filter plates to adsorb and collect metal debris in the waste oil. However, in actual use, since the magnetic rod is fixedly installed in a sliding frame, and the sliding frame is slidably connected to the filter tank through a sliding groove, when cleaning the metal debris on the magnetic rod, the opening of the filter tank of the sliding frame needs to be removed. At this time, the waste oil on the sliding frame may leak out from the opening, causing pollution to the nearby ground. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a primary impurity removal device for waste engine oil to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A primary impurity removal device for waste engine oil includes a processing box with an internal cavity. The cavity has an opening on its upper side and a top cover. One end of the processing box has an oil inlet pipe, and the other end has an oil outlet pipe. A removable filter frame is provided inside the cavity. A movable support assembly is provided on the processing box. A drive component for moving the support is provided on the top cover. A liftable frame plate is provided on the support assembly. Multiple electromagnets are provided inside the frame plate. A removable receiving frame is provided inside the cavity for receiving iron filings attracted to the electromagnets.

[0006] Preferably, the bracket assembly is movably mounted on the processing box, and an electric push rod is provided at the upper end of the top cover and near the oil inlet pipe, with the bracket assembly located at the output end of the electric push rod.

[0007] Preferably, the support assembly includes a horizontal plate and vertical plates on both sides of the horizontal plate. A top plate is provided at the top of the vertical plate. A lifting cavity is formed between the vertical plate, the horizontal plate and the top plate. A limiting groove is provided on the opposite side wall of the vertical plate along its extension direction. A lifting plate that can be raised and lowered is provided in the lifting cavity. The two sides of the lifting plate extend into the limiting groove. A connecting rod that penetrates the horizontal plate is provided on the lifting plate. The bottom end of the connecting rod is fixedly connected to the frame plate.

[0008] Preferably, a rotatable lead screw is provided inside the lifting cavity, and the lead screw thread passes through the lifting plate. The rotation of the lead screw is used to drive the lifting plate to move up and down within the lifting cavity.

[0009] Preferably, a first slot is provided on the side wall of the treatment box below the oil inlet pipe, and an overlapping part is provided on the inner wall of the cavity at the lower end wall of the first slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the liftable arrangement of the frame plate on the support assembly, can drive the electromagnet to approach the metal debris on the filter frame when it is close to the filter frame, and attract the metal debris. After the metal debris has been attracted for a period of time, the frame plate can be moved to drive the electromagnet away from the filter frame, carrying the metal debris away from the waste oil, and cooperating with the receiving frame inserted into the cavity to discharge the metal debris into the receiving frame. Compared with the existing, this application is less likely to cause waste oil leakage when discharging metal debris from the electromagnet, thus preventing pollution of the nearby ground.

[0013] This invention, through the movable arrangement of the support assembly, enables it to move the frame plate and electromagnet within the cavity, thereby adsorbing metal debris at different locations within the filter frame and enhancing the cleaning effect on metal debris.

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0024] The following is in conjunction with the appendix Figures 1-8 This embodiment will be described in further detail.

[0025] Combined with appendix Figures 1-4This embodiment of a waste engine oil primary impurity removal device includes a processing box 100 with an internal cavity. The upper side of the cavity has an opening, and a top cover 120 is fixedly connected to the opening of the cavity by bolts. One end of the processing box 100 is fixedly connected to an oil inlet pipe 110, and the other end of the processing box 100 is fixedly connected to an oil outlet pipe 111. A removable filter frame 101 is provided inside the cavity. A movable support assembly is provided on the processing box 100. A driving component for moving the support assembly is provided on the top cover 120. A liftable frame plate 430 is provided on the support assembly. Multiple electromagnets 432 are fixedly connected to the bottom end of the frame plate 430. A removable receiving frame 102 is provided inside the cavity. The receiving frame 102 is inserted into the cavity to receive iron filings adsorbed on the electromagnets 432.

[0026] In this embodiment, the filter frame 101 is removably disposed in the cavity between the oil inlet pipe 110 and the oil outlet pipe 111. When removing impurities from waste engine oil, the filter frame 101 is first inserted into the cavity, and the waste engine oil is poured into the cavity from the oil inlet pipe 110. A filter screen is fixedly connected inside the filter frame 101 at the bottom. The filter screen can intercept metal fragments and colloids in the waste engine oil and keep them in the filter frame 101, thereby reducing impurities in the waste engine oil. The filtered waste engine oil is discharged through the oil outlet pipe 111 for subsequent deep treatment. When metal debris needs to be removed from the filter frame 101, the frame plate 430 is lowered to extend into the cavity, bringing the electromagnet 432 closer to the filter frame 101. At this time, the electromagnet 432 is energized, making it magnetic, thus enabling it to attract metal debris from the waste oil. Simultaneously, the frame plate 430 can move within the cavity so that the electromagnet 432 on the frame plate 430 can attract metal debris at different locations on the filter frame 101. After attraction is complete, the frame plate 430... 0 and electromagnet 432 are reset in the cavity, and then the frame plate 430 is moved up to allow metal debris to be discharged from the filter frame 101. Then the receiving frame 102 is inserted into the cavity, the power supply to electromagnet 432 is disconnected, electromagnet 432 loses its magnetism, and under the action of gravity, the metal debris finally falls into the receiving frame 102. The receiving frame 102 is moved out of the cavity to collect the metal debris inside. Compared with the existing method, this embodiment is less likely to cause waste oil leakage when discharging metal debris from electromagnet 432, thus avoiding pollution of the nearby ground. The movable bracket assembly allows the frame plate 430 and electromagnet 432 to move within the cavity, thereby adsorbing metal debris at different locations within the filter frame 101 and enhancing the cleaning effect on the metal debris.

[0027] Combination Figures 1-2As shown, in this embodiment, the bottom end of the bracket assembly is slidably mounted on the upper side of the processing box 100 via a slide rail, and an electric push rod 200 is fixedly connected to the upper end of the top cover 120 near the oil inlet pipe 110. The output end of the electric push rod 200 is fixedly connected to the bracket assembly.

[0028] In this embodiment, when it is necessary to move the support assembly, the electric push rod 200 can be activated, thereby driving the support assembly closer to the oil inlet pipe 110 or the oil outlet pipe 111, and finally adsorbing metal debris at different positions on the receiving frame 102.

[0029] Combination Figures 1-4 As shown, in this embodiment, the support assembly includes a horizontal plate 400 and vertical plates 401 disposed on both sides of the horizontal plate 400. A top plate 402 is provided at the top of the vertical plate 401. A lifting cavity is formed between the vertical plate 401, the horizontal plate 400 and the top plate 402. A limiting groove is provided on the opposite side wall of the vertical plate 401 along its extension direction. A lifting plate 410 that can be lifted is provided in the lifting cavity. Both sides of the lifting plate 410 extend into the limiting groove. A connecting rod 431 that penetrates the horizontal plate 400 is provided on the lifting plate 410. The bottom end of the connecting rod 431 is fixedly connected to the frame plate 430.

[0030] In this embodiment, when the frame plate 430 needs to be raised or lowered, the lifting plate 410 can be moved within the lifting cavity, and under the drive of the connecting rod 431, the frame plate 430 and the electromagnet 432 can be raised or lowered as a whole. Specifically, in order to achieve the lifting of the lifting plate 410, a lead screw 421 is rotatably connected to the lifting cavity through a bearing. The lead screw 421 is threaded through the lifting plate 410. Since the lifting plate 410 is restricted by the limiting groove, when the lead screw 421 rotates, the frame plate 430 will move along the axial direction of the lead screw 421, thereby driving the connecting rod 431, the frame plate 430 and the electromagnet 432 to rise and fall accordingly. It should be noted that a motor 420 is fixedly connected to the upper end face of the top plate 402, and the output shaft of the motor 420 is fixedly connected to the lead screw 421, thereby realizing the control of the rotation of the lead screw 421.

[0031] Combination Figures 1-8 As shown, in this embodiment, a first slot 300 is provided on the side wall of the processing box 100 and below the oil inlet pipe 110. An overlapping part 600 is fixedly connected to the inner wall of the cavity and at the lower end wall of the first slot 300. The overlapping part 600 is used to support the filter frame 101. Bolts for fixing the filter frame 101 are provided on the side wall of the processing box 100.

[0032] In this embodiment, the filter frame 101 is aligned with the opening of the first slot 300 and inserted. The overlapping part 600 can support the bottom of the filter frame 101. When the filter frame 101 is fully inserted into the first slot 300, the filter frame 101 can be fixed by bolts. Specifically, the outer wall of the filter frame 101 fits against the inner wall of the cavity, and the outer wall of the filter frame 101 is fixedly connected with a rubber pad. This reduces the possibility of waste oil being discharged into the bottom of the cavity through the gap between the two. After the filter frame 101 is installed in the cavity, the waste oil discharged into the cavity from the oil inlet pipe 110 will first contact the filter frame 101 and the filter screen to intercept metal debris and gum in the waste oil. The filtered waste oil falls to the bottom of the cavity and is finally discharged from the oil outlet pipe 111.

[0033] Combination Figures 1-8 As shown, in this embodiment, a second slot 700 is provided on the side wall of the processing box 100 above the oil outlet pipe 111. The length of the second slot 700 is greater than the length of the cavity and extends into the cavity, thereby allowing the receiving frame 102 to be inserted into the second slot 700. Bolts for fixing the receiving frame 102 are provided on the side wall of the processing box 100.

[0034] In this embodiment, the receiver frame 102 is aligned with the second slot 700 and inserted to install the receiver frame 102 in the cavity. When it is necessary to remove the receiver frame 102, the bolts are released to fix it, and the receiver frame 102 can be pulled out along the second slot 700.

[0035] Specifically, in order to promote the flow of waste oil in the cavity, an inclined plate 800 is fixedly connected to the cavity. The side of the inclined plate 800 near the oil inlet pipe 110 is higher, and the side of the inclined plate 800 near the oil outlet pipe 111 is lower, so that the waste oil in the cavity can flow towards the direction of the oil outlet pipe 111.

[0036] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
