Description

Technical Field

[0001] This utility model relates to the field of emulsion filtration technology, and in particular to a cleaning device suitable for emulsion filter cartridges. Background Technology

[0002] Emulsion filter elements are indispensable core components in industrial cooling and lubrication systems, primarily used to purify circulating emulsions, ensuring their cleanliness and stable performance. In industries such as metal processing, automotive manufacturing, and metallurgy, emulsions, used as coolants and lubricants, are prone to contamination with metal shavings, oil, and gum residues. If these contaminants are not removed promptly, they can accelerate equipment wear, clog pipelines, and in severe cases, lead to decreased machine tool precision or scratches on the surface of machined parts. Over time, contaminants accumulate on the filter element surface, causing blockages. Therefore, regular cleaning of the filter element is necessary to ensure its unobstructed flow.

[0003] A search revealed a Chinese patent with publication number CN220513579U, which discloses a self-cleaning emulsion filter, comprising an outer cylinder, a filter element, a cleaning component, a lifting mechanism, and a top cylinder. The filter element is housed inside the outer cylinder, and the cleaning component is housed inside the filter element. The top cylinder is fixed at the top center of the outer cylinder, and the two are connected. The lifting mechanism is fixed on the outer side of the outer cylinder and is used to adjust the position of the cleaning component.

[0004] To address the problem that the aforementioned technologies lack components for effectively cleaning the outside of the filter element, and that when the external filter pores are severely clogged, it is difficult to effectively clean the external blockage using only internal backwashing pressure, a cleaning device suitable for emulsion filter elements is proposed.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-6 As shown, a cleaning device for emulsion filter cartridges includes a filter tank 1 with a filter cartridge 19 fixedly installed inside. A one-way drive wheel 15 and a drive ring 16 are rotatably connected to the top of the filter tank 1. A spiral scraper 18 is fixedly connected below the drive ring 16. The spiral scraper 18 is a counterclockwise selectable scraper. Multiple triangular grooves 17 are opened above the drive ring 16. Multiple limiting plates 23 are fixedly connected to one side of the one-way drive wheel 15. Multiple drive claws 14 are rotatably connected to the inner side of the limiting plate 23. A spring 24 is fixedly connected to one end of the drive claw 14's rotating shaft and the outer side of the limiting plate 23. A synchronization component is fixedly connected to the other side of the one-way drive wheel 15.

[0031] When the drive ring 16 rotates counterclockwise under the drive of the one-way drive wheel 15 and the synchronization component, the drive claw 14 on one side of the one-way drive wheel 15 is blocked by the limiting plate 23, which can squeeze the triangular groove 17 on the drive ring 16. The spiral scraper 18 can be used to clean the outside of the filter hole of the filter cartridge 19. This can remove the contaminants attached to the outside of the filter cartridge 19 before backwashing, which can make the backwashing effect better.

[0032] At the same time, the counterclockwise rotating spiral scraper 18 can push the scraped pollutants to the bottom of the filter tank 1 for accumulation and storage;

[0033] When the synchronization component reverses and drives the back-flush component to reset, the drive claw 14 reverses. Since the other side of the drive claw 14 is not restricted, it can rotate freely, thus preventing the spiral scraper 18 from reversing and preventing contaminants at the bottom from being scooped up.

[0034] In this embodiment, a top support frame 8 is fixedly connected above the filter tank 1, a lifting motor 9 is fixedly connected above the top support frame 8, and a bevel gear 11 is fixedly connected to the power output end of the lifting motor 9.

[0035] The synchronization assembly includes a second bevel gear 12 and multiple synchronization pulleys 13. The upper synchronization pulley 13 is fixedly connected to one side of the second bevel gear 12, and the lower synchronization pulley 13 is fixedly connected to one side of the one-way drive wheel 15. The multiple synchronization pulleys 13 are connected by belt drive. One side of the first bevel gear 11 meshes with the second bevel gear 12. The first bevel gear 11 and the second bevel gear 12 are rotatably connected to the top support frame 8.

[0036] When the lifting motor 9 starts, it can drive the bevel gear 11 to rotate, which in turn drives the multiple synchronous pulleys 13 on one side to rotate through the bevel gear 2 12, which in turn drives the one-way drive wheel 15 below to rotate.

[0037] In this embodiment, an inlet 2 is fixedly connected to one side of the filter tank 1, and a drain 3 and a sludge outlet 4 are fixedly connected to the bottom of the filter tank 1. The inlet 2 injects the emulsion to be treated into the filter tank 1, and after being filtered through the filter cartridge 19, the emulsion is discharged from the drain 3 at the bottom. The sludge outlet 4 is used to discharge the pollutants accumulated at the bottom. There are solenoid valves on one side of the inlet 2, the drain 3 and the sludge outlet 4 that can be used for switching.

[0038] In this embodiment, a lifting slide rod 7 is fixedly connected below the top support frame 8, a screw rod 10 is fixedly connected to the power output end of the lifting motor 9, a lifting support plate 25 is slidably connected to one side of the lifting slide rod 7, the other end of the lifting support plate 25 is threadedly connected to the screw rod 10 through a screw nut, a backwash pipe 5 is fixedly connected to the other end of the lifting support plate 25, and a backwash pump 6 is fixedly connected to the water inlet end of the backwash pipe 5.

[0039] A backwash nozzle 21 is fixedly connected to one end of the backwash pipe 5 outlet, and an internal scraper 22 is fixedly connected to the lower end of the backwash nozzle 21.

[0040] When the lifting motor 9 is working, it can drive the screw 10 to rotate, which in turn causes the lifting support plate 25 to move the backwash pipe 5 downward. This allows the internal scraper 22 to clean the inside, and at the same time, high-pressure water can be sprayed from the spray nozzles around the backwash nozzle 21 through the backwash pipe 5 to backwash and clean the filter cartridge 19.

[0041] When the backwash nozzle 21 descends, it can drive the spiral scraper 18 to rotate counterclockwise, cleaning the outside before backwashing.

[0042] In this embodiment: when the drive ring 16 rotates counterclockwise under the drive of the one-way drive wheel 15 and the synchronization component, the drive claw 14 on one side of the one-way drive wheel 15 is blocked by the limiting plate 23, which can squeeze the triangular groove 17 on the drive ring 16. The spiral scraper 18 can be used to clean the outside of the filter hole of the filter cartridge 19. In this way, the contaminants attached to the outside of the filter cartridge 19 can be removed first before backflushing, which can make the backflushing effect better.

[0043] At the same time, the counterclockwise rotating spiral scraper 18 can push the scraped pollutants to the bottom of the filter tank 1 for accumulation and storage;

[0044] When the synchronization component reverses and drives the back-flush component to reset, the drive claw 14 reverses. Since the other side of the drive claw 14 is not restricted, it can rotate freely, thus preventing the spiral scraper 18 from reversing and preventing contaminants at the bottom from being scooped up.

[0045] When the lifting motor 9 starts, it drives the bevel gear 11 to rotate, which in turn drives the multiple synchronous pulleys 13 on one side to rotate through the bevel gear 12. At this time, it drives the one-way drive wheel 15 below to rotate. The liquid inlet 2 injects the emulsion to be processed into the filter tank 1. After being filtered through the filter cartridge 19, the emulsion is discharged from the drain outlet 3 at the bottom. The drain outlet 4 is used to discharge the pollutants accumulated at the bottom. There are solenoid valves on one side of the liquid inlet 2, the drain outlet 3 and the drain outlet 4 for switching.

[0046] When the lifting motor 9 is working, it can drive the screw 10 to rotate, which in turn causes the lifting support plate 25 to move the backwash pipe 5 downward. This allows the internal scraper 22 to clean the inside, and at the same time, high-pressure water can be sprayed from the spray nozzles around the backwash nozzle 21 through the backwash pipe 5 to backwash and clean the filter cartridge 19.

[0047] When the backwash nozzle 21 descends, it can drive the spiral scraper 18 to rotate counterclockwise, cleaning the outside before backwashing.

[0048] Example 2:

[0049] A cleaning device for emulsion filter cartridges is provided in this embodiment, which is an improvement on Embodiment 1, as follows: Figure 1-6 As shown,

[0050] In this embodiment, an ultrasonic generator 20 is fixedly connected to the top of the filter tank 1, and one end of the probe of the ultrasonic generator 20 is fixedly connected to the filter cylinder 19 below.

[0051] Before backwashing, the ultrasonic generator 20 can be activated to vibrate the filter cartridge 19, making it easier for contaminants to be scraped off and backwashed.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
