Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a self-cleaning activated carbon filter. Background Technology

[0002] Activated carbon filter cartridges are made from high-quality fruit shell charcoal and coal-based activated carbon, supplemented with food-grade binders, and processed using high-tech techniques and special processes. They integrate adsorption, filtration, interception, and catalysis, effectively removing organic matter, residual chlorine, and other radioactive substances from water, and also have decolorizing and odor-removing effects. They are an ideal next-generation product for the liquid and air purification industries. Currently, existing activated carbon filter cartridges tend to accumulate a large amount of impurities on their surface after prolonged adsorption and filtration, which severely affects their performance and reduces their lifespan. Cleaning these cartridges typically involves disassembling them and manually cleaning them, which is inconvenient, time-consuming, and labor-intensive. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background section.

[0004] The present invention adopts the following technical solution: a self-cleaning activated carbon filter element, comprising a cylindrical body, wherein a filter element body is disposed inside the cylindrical body, a bucket cover is fixedly connected to the top of the cylindrical body, an air inlet pipe is fixedly connected to the surface of the bucket cover, a motor is fixedly connected to the surface of the cylindrical body, a rotating shaft is fixedly connected to the output end of the motor, a connecting rod is fixedly connected to the surface of the rotating shaft, and a scraper is fixedly connected to one end of the connecting rod.

[0005] Preferably, one end of the connecting rod has a groove, and a connecting block is fixedly connected to the surface of the scraper. The connecting block is slidably connected inside the groove, and a first spring is installed inside the groove. One end of the first spring is fixedly connected to the connecting block. This design ensures that the scraper remains in contact with the inner wall of the filter element body, improving the cleaning effect.

[0006] Preferably, there are two sets of scrapers, which are symmetrically distributed on both sides of the middle part of the filter element body. This improves the efficiency of the scrapers in cleaning impurities on the inner wall of the filter element body and shortens the cleaning time.

[0007] Preferably, a second ring is fixedly connected to the lower surface of the lid, and a first fixing ring is fixedly connected to the inner bottom surface of the cylinder. This design allows for the fixation and positioning of the filter element body within the cylinder, preventing it from shaking during use.

[0008] Preferably, a collection compartment is fixedly connected inside the cylinder, and a debris collection box is provided inside the collection compartment. Here, impurities scraped off from the inner wall of the filter element body can be collected, preventing impurities from accumulating inside the cylinder and affecting its use.

[0009] Preferably, the surface of the storage compartment has an insertion hole, the surface of the chip collection box is fixedly connected to a sleeve, the inside of the sleeve is slidably connected to a pin, the surface of the pin is fixedly connected to a pull rod, the surface of the pull rod is fitted with a second spring, and the pin is inserted into the insertion hole. This design allows the chip collection box to be fixed to the storage compartment, while also facilitating the disassembly and assembly of the chip collection box, making it easier to remove the chip collection box from the storage compartment and reducing the working time required to remove it.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. This utility model, by setting up a motor, rotating shaft, connecting rod, and scraper structure, allows for the automatic removal of impurities from the inner wall of the filter element body after prolonged use. This eliminates the need to clean the impurities without affecting the filter element's air filtration efficiency. The motor is started first, and its output drives the rotating shaft to rotate. Simultaneously, the rotating shaft drives the connecting rod and scraper to rotate, and the scraper removes the impurities adhering to the inner wall of the filter element body. This eliminates the need to periodically disassemble the filter element body for separate cleaning, improving the convenience and efficiency of cleaning the filter element body.

[0012] 2. This utility model, through the setting of a sleeve, pin, pull rod, and spring structure, allows the debris to fall into the dust collection box inside the storage compartment after the impurities on the inner wall of the filter element body are cleaned periodically. When a certain amount of impurities accumulate in the dust collection box, it needs to be removed from the storage compartment for centralized processing of the impurities. At this time, the pull rod needs to be moved, which causes the pin to slide inside the sleeve and compress the second spring. Then, the pin disengages from the insertion hole on the storage compartment, and the dust collection box can be removed from the storage compartment for processing of the impurities. This achieves the goal of fixing the dust collection box to the storage compartment and also facilitates the disassembly and assembly of the dust collection box, making it easier to remove the dust collection box from the storage compartment and shortening the working time required to remove the dust collection box from the storage compartment.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] Please see Figure 1-5This utility model provides a technical solution: a self-cleaning activated carbon filter element, including a cylindrical body 1, a filter element body 6 disposed inside the cylindrical body 1, a lid fixedly connected to the top of the cylindrical body 1, an air inlet pipe 5 fixedly connected to the surface of the lid, a motor 7 fixedly connected to the surface of the cylindrical body 1, a rotating shaft 8 fixedly connected to the output end of the motor 7, a connecting rod 9 fixedly connected to the surface of the rotating shaft 8, a scraper 10 fixedly connected to one end of the connecting rod 9, a groove 11 formed at one end of the connecting rod 9, a connecting block 12 fixedly connected to the surface of the scraper 10, the connecting block 12 slidably connected inside the groove 11, and a first-order spring 13 disposed inside the groove 11. One end of the first spring 13 is fixedly connected to the connecting block 12. This allows the scraper 10 to always be in contact with the inner wall of the filter element body 6, improving the cleaning effect. There are two sets of scrapers 10, which are symmetrically distributed on both sides of the middle part of the filter element body 6. This can improve the efficiency of the scraper 10 in cleaning impurities on the inner wall of the filter element body 6 and shorten the cleaning time. A second ring is fixedly connected to the lower surface of the bucket lid, and a first fixing ring 19 is fixedly connected to the inner bottom surface of the cylinder 1. This can fix and limit the filter element body 6 inside the cylinder 1, so that it will not shake during use.

[0024] Example 2

[0025] Please see Figure 5 The cylinder 1 has a fixedly connected storage compartment 3 inside, and a debris collection box 4 is set inside the storage compartment 3. Here, the debris scraped off from the inner wall of the filter element body 6 can be collected to prevent the debris from accumulating inside the cylinder 1 and affecting its use. The surface of the storage compartment 3 has an insertion hole 18. The surface of the debris collection box 4 is fixedly connected to a sleeve 14. The sleeve 14 is slidably connected to a pin 15. The surface of the pin 15 is fixedly connected to a pull rod 17. A second spring 16 is sleeved on the surface of the pull rod 17. The pin 15 is inserted into the insertion hole 18. Here, the debris collection box 4 can be fixed to the storage compartment 3. At the same time, it is also convenient to disassemble and assemble the debris collection box 4, making it easier to take the debris collection box 4 out of the storage compartment 3 and shortening the working time required to take the debris collection box 4 out of the storage compartment 3.

[0026] Working Principle: During use, air is first delivered to the internal cavity of the filter body 6 through the air inlet pipe 5. The air is then filtered by the filter body 6 and discharged from the cylinder 1. After prolonged use, a large amount of impurities will adhere to the inner wall of the filter body 6. To avoid affecting the filtration effect of the filter body 6, it is necessary to clean the impurities on the inner wall of the filter body 6. First, the motor 7 on the cylinder cover 2 is started. The output end of the motor 7 drives the rotating shaft 8 to rotate. At the same time, the rotating shaft 8 drives the connecting rod 9 and the scraper 10 to rotate. The connecting block 12 in the slide groove 11 on the connecting rod 9 keeps the scraper 10 in contact with the inner wall of the filter body 6 under the elastic force of the first spring 13. The scraper 10 scrapes off the impurities attached to the inner wall of the filter body 6. Under the constraint of the first fixed ring 19 and the second fixed ring 20, the filter body 6 remains stable and does not shake in the cylinder 1, realizing automatic cleaning of the impurities on the inner wall of the filter body 6. The filter element body 6 is automatically removed, eliminating the need for periodic disassembly and separate cleaning. This improves the convenience and efficiency of cleaning the filter element body 6. After periodic cleaning of the impurities on the inner wall of the filter element body 6, the impurities fall into the chip collection box 4 inside the collection chamber 3. When a certain amount of impurities accumulate in the chip collection box 4, it needs to be removed from the collection chamber 3 for centralized processing. At this time, the pull rod 17 needs to be moved. The pull rod 17 drives the pin 15 to slide inside the sleeve 14 and squeeze the second spring 16. Then, the pin 15 disengages from the insertion hole 18 on the collection chamber 3. The collection box can then be removed from the inside of the collection chamber 3, and the impurities in the collection box can be processed. This allows the chip collection box 4 to be fixed to the collection chamber 3, while also facilitating the disassembly and assembly of the chip collection box 4. This makes it easier to remove the chip collection box 4 from the collection chamber 3 and shortens the working time required to remove the chip collection box 4 from the collection chamber 3.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
