Description

Technical Field

[0001] The utility model relates to the technical field of engine oil recovery, and more specifically, to an environmentally friendly engine oil recovery filter. Background Art

[0002] With the rapid development of the automotive industry, the number of cars on the road continues to climb, leading to an increase in engine oil usage and, inevitably, the generation of large quantities of waste oil. This waste oil contains a variety of harmful substances, such as heavy metals and chemical additives. If not properly handled, waste oil can cause serious pollution to soil, water, and air.

[0003] In Chinese utility model patents, for example, the utility model of CN220941189U discloses a waste oil recovery filter, which relates to the field of waste oil recovery. The filter employs a drive motor, an electromagnet, a rotating bracket, and an iron chip storage box. The drive motor drives the electromagnet to rotate along the rotating bracket, and the electromagnet absorbs iron chip impurities from mixed impurities. When the rotating bracket drives the electromagnet to move to the top of the iron chip storage box, the electromagnet is powered off, and the iron chip impurities on the surface of the electromagnet fall into the iron chip storage box, thereby separating the iron chip impurities from the dust impurities.

[0004] After the above technology uses an electromagnet to adsorb iron filings impurities, gravity alone cannot make all the debris on the electromagnet fall off. On the one hand, some iron filings are closely attached to the surface of the electromagnet during the adsorption process, and gravity alone cannot overcome the combined effect of this adsorption force and friction. At the same time, some iron filings may have oxidized or adhered to other impurities, forming more stubborn attachments, which are difficult to separate from the electromagnet due to gravity. The iron filings that have not completely fallen off will continue to rotate with the electromagnet and may be mixed with other impurities again, affecting the subsequent separation effect, requiring the entire separation process to be repeated, wasting time and energy. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide an environmentally friendly oil recovery filter. The technical problem to be solved by the present invention is that gravity alone cannot make all the debris on the electromagnet fall off. The iron filings that have not completely fallen off will continue to rotate with the electromagnet and may be mixed with other impurities again, affecting the subsequent separation effect, so that the entire separation process needs to be repeated, wasting time and energy.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An environmentally friendly oil recovery filter includes a filter box, the top surface of the filter box is rotatably connected to a rotating shaft, a plurality of telescopic seats are symmetrically installed on the outside of the rotating shaft, each of the telescopic seats is elastically slidably connected to a sliding rod, and an electromagnet is rotatably connected between two sliding rods in corresponding positions, and both ends of each electromagnet pass through the sliding rod and are installed with gears, a fixed plate is fixedly installed on one side of the top surface of the filter box, a plurality of tooth plates are symmetrically installed on the side of the fixed plate, and each tooth plate is meshed with a gear in the corresponding position, and a brush is installed on the outside of the fixed plate.

[0008] like Figure 1-3 As shown, the specific implementation method is: by arranging a telescopic seat and a sliding rod, the electromagnet can be tightly attached to the arc filter plate in the filter box, so that iron filings and impurities can be effectively adsorbed and dust can be pushed out. At the same time, through the arrangement of the gear and the tooth plate, when the gear and the tooth plate are engaged, the rotation of the rotating shaft can drive the gear to rotate, and then drive the electromagnet to rotate, so that the iron filings on the electromagnet are cleaned by the brush, and then the iron filings fall from the electromagnet into the collection box.

[0009] In a preferred embodiment, a movable groove is provided on the outer side of each telescopic seat, and a handle is fixedly mounted on the outer side of each slide rod, and the handle is movably connected in the movable groove at a corresponding position.

[0010] In a preferred embodiment, a plurality of arc-shaped limiting rods are symmetrically installed on the top surface of the filter box, and each arc-shaped limiting rod is slidably connected to a handle at a corresponding position.

[0011] In a preferred embodiment, a sliding groove is provided in each of the telescopic seats, and each sliding rod is slidably connected in the sliding groove at a corresponding position, and a spring is commonly installed between the bottom wall of each sliding groove and the outer side of the sliding rod.

[0012] In a preferred embodiment, a baffle is fixedly mounted on the outer side of each slide rod, and each side surface of the baffle is in contact with the inner wall of the slide groove.

[0013] In a preferred embodiment, two brackets are symmetrically installed on the top surface of the filter box, and the two ends of the rotating shaft are rotatably connected to the outer sides of the brackets at corresponding positions. A motor is fixedly installed on the outer side of one of the brackets, and the output shaft of the motor passes through the bracket and is connected to the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model realizes that the gear plate and the gear are automatically engaged under the joint action of the rotation of the shaft and the spring by arranging gears, electromagnets, springs, tooth plates, brushes and other devices, and the gear rotates under the action of the tooth plate, thereby driving the electromagnet to rotate, and the debris on the electromagnet is cleaned by the brush and falls into the collection box.

[0016] 2. The utility model realizes that the handle slides along the arc of the arc limit rod by setting an arc limit rod, a spring and other devices, thereby driving the slide rod to compress the spring. When the slide rod contacts the filter plate again, the spring is in a compressed state, and the electromagnet can be tightly attached to the filter plate again, thereby more effectively absorbing iron filings and impurities near the arc filter plate.

[0017] To sum up, the utility model is simple to operate when in use. The electromagnet automatically rotates and contacts the brush, and the electromagnet is cleaned by the brush to prevent residual iron filings and impurities from entering the engine oil again. At the same time, the electromagnet and the filter plate can be tightly attached to each other, so that the iron filings and impurities near the arc filter plate can be more effectively adsorbed.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-3, an environmentally friendly oil recovery filter, including a filter box 1, the top surface of the filter box 1 is rotatably connected to a rotating shaft 7, a plurality of telescopic seats 8 are symmetrically installed on the outside of the rotating shaft 7, each telescopic seat 8 is elastically slidably connected to a slide rod 9, and an electromagnet 10 is rotatably connected between the two slide rods 9 in corresponding positions. Both ends of each electromagnet 10 pass through the slide rod 9 and are installed with a gear 11. A fixing plate 4 is fixedly installed on one side of the top surface of the filter box 1, and a plurality of tooth plates 5 are symmetrically installed on the side of the fixing plate 4, and each tooth plate 5 is meshed with the gear 11 corresponding to the position, and a brush 6 is installed on the outside of the fixed plate 4.

[0024] like Figure 1-3 As shown, the specific implementation method is as follows: by arranging the telescopic seat 8 and the slide rod 9, the electromagnet 10 can be tightly attached to the arc filter plate in the filter box 1, so that iron filings and impurities can be effectively adsorbed and dust can be pushed out. At the same time, through the arrangement of the gear 11 and the tooth plate 5, when the gear 11 is engaged with the tooth plate 5, the rotation of the rotating shaft 7 can drive the gear 11 to rotate, and then drive the electromagnet 10 to rotate, so that the iron filings on the electromagnet 10 are cleaned by the brush 6, and then the iron filings fall from the electromagnet 10 into the collection box.

[0025] It is worth noting that the specific separation and storage of dust and iron filings impurities have been described in detail in the comparative technology and will not be repeated here.

[0026] A movable slot 15 is formed on the outer side of each telescopic seat 8 , and a handle 16 is fixedly mounted on the outer side of each slide rod 9 , and the handle 16 is movably connected to the movable slot 15 at a corresponding position.

[0027] A plurality of arc-shaped limiting rods 12 are symmetrically mounted on the top surface of the filter box 1 , and each arc-shaped limiting rod 12 is slidably connected to a handle 16 at a corresponding position.

[0028] It is worth noting that the handle 16 is driven to slide into the telescopic seat 8 by the arc-shaped limiting rod 12 , thereby driving the slide rod 9 to slide, thereby making it easier for the slide rod 9 to fit tightly against the filter plate in the filter box 1 .

[0029] A sliding groove is provided in each telescopic seat 8 , and each slide rod 9 is slidably connected in the sliding groove at a corresponding position. A spring 14 is commonly installed between the bottom wall of each sliding groove and the outer side of the slide rod 9 .

[0030] Each slide bar 9 can slide outwards by the action of the spring 14 .

[0031] A baffle 13 is fixedly mounted on the outer side of each slide bar 9 , and each side surface of the baffle 13 is in contact with the inner wall of the slide groove, so that the baffle 13 prevents the slide bar 9 from being separated from the telescopic seat 8 .

[0032] Two brackets 2 are symmetrically installed on the top surface of the filter box 1, and the two ends of the rotating shaft 7 are rotatably connected to the outer sides of the brackets 2 at corresponding positions. A motor 3 is fixedly installed on the outer side of one of the brackets 2, and the output shaft of the motor 3 passes through the bracket 2 and is connected to the rotating shaft 7. The driving source is provided by the drive of the motor 3 and the rotating shaft 7.

[0033] When the utility model is used, first, the engine oil is injected through the oil inlet of the filter box 1 and filtered through the filter plate. Then, the motor 3 is started to drive the rotating shaft 7 to rotate, so that each telescopic seat 8 and the slide rod 9 start to rotate. Then, each slide rod 9 makes the electromagnet 10 and the filter plate tightly attached under the force of the spring 14. When the electromagnet 10 and the arc filter plate are attached, the strong magnetic force can penetrate the tiny pores of the filter plate and suck out the iron chips hidden in the filter plate structure, thereby greatly improving the adsorption rate and separation effect of iron chips impurities.

[0034] Then, as the shaft 7 continues to rotate, the electromagnet 10 is driven to approach the fixed plate 4. At this time, the electromagnet 10 is powered off and demagnetized. Under the action of the spring 14, the toothed plate 5 is brought into contact with the gear 11. As the shaft 7 continues to rotate, the spring 14 automatically meshes the toothed plate 5 with the gear 11. As the gear 11 rotates under the action of the toothed plate 5, the electromagnet 10 is mobilized to rotate, and the debris on the electromagnet 10 is cleaned by the brush 6 and falls into the collection box.

[0035] As the slide bar 9 continues to rotate, the handle 16 contacts the top end of the arc-shaped limit bar 12 and slides along the curvature of the arc-shaped limit bar 12, so that the handle 16 slides into the telescopic seat 8, thereby driving the slide bar 9 to compress the spring 14. When the slide bar 9 contacts the filter plate again, the spring 14 is in a compressed state, and the electromagnet 10 can be tightly attached to the filter plate again.

[0036] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
