[0002] Filter cartridges are a professional term for filtration and purification functions. They are used to purify raw fluids and facilitate the separation of resources. Currently, filter cartridges are mainly used in filtration industries such as oil filtration, air filtration, and water filtration. After use, filter cartridges accumulate a lot of dust and impurities on their surface, requiring cleaning. Filters consume a large number of filter cartridges during use. As the main consumable material of air compressor filtration devices, filter cartridges need to be replaced frequently, which undoubtedly increases the production costs of enterprises.

[0003] In existing technologies, when cleaning used filter elements for reuse, direct air blowing is generally used to clean the filter elements from the inside out or from the outside in. However, the thickness of air filter elements is generally 100mm. When cleaning the filter elements with direct air blowing, the air pressure is not high enough to remove the dust and oil that have been adhering to the outside of the filter elements for a long time.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a filter element cleaning device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7This utility model provides a filter cartridge cleaning device, including a cleaning tank 1. Support legs 2 are installed at the bottom of the cleaning tank 1. A conical bottom shell 3 is integrally connected to the bottom end of the cleaning tank 1. An overflow port is provided on one side of the top of the cleaning tank 1, and an L-shaped connecting pipe 4 is installed on the overflow port. The support legs 2 at the bottom of the cleaning tank 1 provide support. Demineralized water is added to the cleaning tank 1 through the overflow port in conjunction with the L-shaped connecting pipe 4. The L-shaped connecting pipe 4 is connected to the bottom end of the conical bottom shell 3 via a control valve, and a wastewater treatment component 5 is installed at the bottom end of the L-shaped connecting pipe 4. A turbulence-type cleaning component 6 extending into one side of the cleaning tank 1 is provided. An upper filter element limiting component 7 is arranged inside the cleaning tank 1. The sewage discharged from the bottom of the conical bottom shell 3 can be collected by the lower sewage treatment component 5 to clean the impurities in the sewage. The turbulence-type cleaning component 6 facilitates the installation of the filter element and allows the backflushing steam inlet 10 to be opened to backflush the three sets of filter elements with steam in groups. When backflushing one set, the inlet valves of the other two sets are closed, which raises the temperature of the demineralized water, so that the oily impurities on the surface of the filter element are better dissolved and removed under the action of backflushing air.

[0027] In one embodiment, please refer to the appendix to the specification. Figure 4 As shown, the turbulence cleaning assembly 6 includes an external horizontal pipe 8. High-pressure water gun inlet 9 and backflush steam inlet 10 are respectively provided at both ends of the external horizontal pipe 8. A cleaning pipe 12 extending into the cleaning tank 1 is connected to the external horizontal pipe 8. Electromagnetic control valves 11 are provided at the connection between the cleaning pipe 12 and the external horizontal pipe 8. An opening 13 is provided on the cleaning pipe 12. A filter element support ring 14 is installed in the opening 13. A filter element pull rod 15 is installed at the center of the filter element support ring 14. The cleaning pipe 12 is divided into three groups. The first group of cleaning pipes 12 and the third group of cleaning pipes 12 are each provided with four openings 13. The second group of cleaning pipes 12 is provided with three openings 13. By inserting the filter element into the filter element pull rod 15, with the bottom abutting against the filter element support ring 14, the high-pressure water gun inlet 9 can be easily connected to an external high-pressure water gun. Steam enters through the backflushing steam inlet 10, heating and blowing away impurities attached to the filter element layer and surface from the inside out. Finally, air is introduced, causing the liquid inside the equipment to form turbulence, backflushing and cleaning the outer surface of the filter element, causing the filter cake impurities attached to the filter element surface to detach from the filter element and settle to the bottom of the equipment under gravity. When backflushing, the electromagnetic control valve 11 closes the other two inlet valves while one set is backflushing, causing the temperature of the demineralized water to rise, thereby allowing the oily impurities on the surface of the filter element to dissolve and fall off better under the action of the backflushing air.

[0028] In one embodiment, please refer to the appendix to the specification. Figure 5As shown, the upper filter element limiting assembly 7 includes an upper threaded positioning post 16 integrally connected to the top of the filter element pull rod 15.

An upper limit cover 26 is installed on the top of the steel wire outer mesh cylinder 25. The center of the upper limit cover 26 is connected to the bottom end of the L-shaped connecting pipe 4 through a fixing sleeve 27. An inner filter cylinder 28 is provided inside the steel wire outer mesh cylinder 25. A central filter core 29 is installed inside the inner filter cylinder 28. A number of filter holes 30 are provided on the central filter core 29. An activated carbon filter layer is formed between the central filter core 29 and the inner filter cylinder 28. The activated carbon filter layer, in conjunction with the filter holes 30, adsorbs and filters the oil stains in the sewage. After filtration in conjunction with the inner filter cylinder 28, the water flows out from the outer wire mesh cylinder 25 and enters the water storage tank 21. The drainage pipe 22, in conjunction with the sealing plug 23, facilitates the discharge of water.

[0030] In one embodiment, please refer to the appendix to the specification. Figure 1 and 3 As shown, the bottom end of the external horizontal pipe 8 is connected to a liquid collection bag 31. The bottom end of the liquid collection bag 31 is provided with a connecting horizontal pipe, and the two ends of the connecting horizontal pipe are respectively provided with a backflush inlet 32 ​​and a cleaning fluid inlet 33.

[0031] In practical applications, a support leg 2 is installed at the bottom of the cleaning tank 1 for support. An overflow port is provided in conjunction with an L-shaped connecting pipe 4 to add demineralized water into the cleaning tank 1 to the overflow port. The wastewater treatment component 5 can collect the wastewater discharged from the bottom of the conical bottom shell 3 and clean the impurities in the wastewater. The turbulence-type cleaning component 6 facilitates the installation of the filter element and allows the backflushing steam inlet 10 to be opened to backflush the three sets of filter elements with steam in groups. When one set is backflushed, the inlet valves of the other two sets are closed, which raises the temperature of the demineralized water and makes the oily impurities on the surface of the filter element better dissolve and fall off under the action of backflushing air. This utility model has a simple structure, effectively filters multiple sets of filter elements, uses backflushing air to dissolve and remove oil from the surface of the filter element, and can treat the wastewater after filtration for convenient reuse.
