[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a high-efficiency filter for wastewater treatment, such as... Figure 1-3As shown, the high-efficiency filter for wastewater treatment includes: a filter box 1 with an inlet pipe 2 fixedly installed at the top; a filter hopper 3 fixedly installed inside the filter box 1; an activated carbon filter plate 4 fixedly installed inside the filter box 1 and positioned below the filter hopper 3; a drain pipe 5 fixedly installed on the filter box 1; a piston 6 slidably installed on the filter box 1 and positioned below the activated carbon filter plate 4; a connecting rod 7 fixedly installed below the piston 6 and slidably extending outside the filter box 1; a drive ring 8 fixedly installed at the bottom of the connecting rod 7; a reciprocating motor 9 fixedly installed at the bottom of the filter box 1; and a drive rod 10, one end of which is fixedly installed on the output shaft of the reciprocating motor 9, and the other end of which is slidably embedded in the drive ring 8.

[0021] In this embodiment, the filter box 1 serves as the main body of the entire filter, housing and supporting the internal filter components. An inlet pipe 2 is fixedly installed at the top, introducing the wastewater to be treated, serving as the channel for the wastewater to enter the filter. The filter bucket 3 performs preliminary filtration of the wastewater, removing particulate impurities such as sand and gravel, preventing these impurities from clogging or damaging subsequent filter components. The activated carbon filter plate 4 further filters impurities and harmful substances from the wastewater, utilizing its adsorption properties to improve water quality. The drain pipe 5 discharges the filtered water. Moving the piston 6 up and down can help improve filtration efficiency and may also be used to discharge sediment or perform backwashing. The connecting rod 7 connects to and drives the piston 6. The drive ring 8 transmits the driving force of the reciprocating motor to the piston 6. The reciprocating motor 9 serves as the power source for driving the piston 6 up and down. The drive rod 10 converts the reciprocating rotation of the motor into the linear up and down motion of the piston 6. By using the filter bucket 3 for preliminary filtration, large particulate impurities in the wastewater are effectively removed, protecting subsequent filter components from clogging and damage. The inclusion of activated carbon filter plate 4 improves filtration efficiency and quality, removing more harmful substances from wastewater and enhancing water quality. The overall structure is compact and rational, improving wastewater treatment efficiency and quality, and facilitating the recycling of water resources.

[0022] In a further preferred embodiment of the present invention, the drain pipe 5 is disposed between the activated carbon filter plate 4 and the piston 6, and a valve is fixedly installed on the drain pipe 5.

[0023] In this embodiment, the drain pipe 5 is specifically positioned between the activated carbon filter plate 4 and the piston 6. This design means that after being filtered by the activated carbon filter plate 4, wastewater flows into the space above the piston 6 and is then discharged through the drain pipe 5. This arrangement ensures that only fully filtered clean water is discharged, improving the quality of the effluent. The valve allows the user to control the opening and closing of the drain pipe 5 as needed, thereby achieving precise control of the effluent flow rate. Furthermore, closing the valve during filter maintenance or cleaning prevents accidental leakage of wastewater or cleaning fluid, improving operational safety and convenience.

[0024] In a further preferred embodiment of this utility model, a filter screen 11 is slidably installed inside the filter box 1, the filter screen 11 is in slidable contact with the filter bucket 3, the fixing rod 12 is fixedly installed on the filter screen 11, the other end of the filter screen 11 extends to the outside of the filter box 1, a connecting plate 13 is fixedly installed between the fixing rods 12, and a reciprocating mechanism is provided on the top of the filter box 1 to drive the filter screen 11 to reciprocate.

[0025] In this embodiment, the filter screen 11 provides an additional filtration layer, which helps to further remove fine impurities from wastewater and improve the quality of the effluent. Its sliding installation design allows the filter screen 11 to reciprocate during the filtration process, thereby enhancing the filtration effect. The fixing rod 12 supports and fixes the position of the filter screen 11 and also serves as a connection and transmission mechanism, transmitting the driving force of the reciprocating mechanism to the filter screen 11. A stable structure is formed between the connecting plate 13 and the fixing rod 12, which helps to enhance the stability and strength of the filter screen 11. The reciprocating mechanism is correspondingly arranged with the connecting plate 13 to drive the filter screen 11 to reciprocate. The reciprocating mechanism allows the filter screen 11 to vibrate or move continuously during the filtration process, helping to prevent impurities from clogging the mesh and improving filtration efficiency.

[0026] In a further preferred embodiment of this utility model, the reciprocating mechanism includes a drive motor 14, a turntable 15, an eccentric shaft 16, and a push rod 17. The drive motor 14 is fixedly mounted on the filter box 1, the turntable 15 is fixedly mounted on the output shaft of the drive motor 14, the eccentric shaft 16 is fixedly mounted on the turntable 15, the push rod 17 is rotatably mounted on the eccentric shaft 16, and the other end of the push rod 17 is hinged to the connecting plate 13.

[0027] In this embodiment, the drive motor 14 serves as the power source for the reciprocating mechanism. The rotary output shaft of the drive motor 14 drives the turntable 15 to rotate. The turntable 15 acts as a support and transmission component for the eccentric shaft 16, converting the rotational motion of the drive motor 14 into the eccentric rotational motion of the eccentric shaft 16. The push rod 17 acts as a transmission component, converting the eccentric rotational motion of the eccentric shaft 16 into the reciprocating linear motion of the filter screen 11. Hinged on the connecting plate 13, the push rod 17 can push the filter screen 11 to reciprocate within the filter box 1. The design of the reciprocating mechanism allows the filter screen 11 to reciprocate during the filtration process, thereby continuously vibrating or moving, preventing impurities from clogging the mesh and improving filtration efficiency. Through the reciprocating motion of the filter screen 11 and multi-layer filtration, impurities and harmful substances in wastewater can be removed more effectively, thereby improving the quality of the effluent. By adjusting the rotational speed of the drive motor 14 and the eccentricity of the eccentric shaft 16, the frequency and amplitude of the reciprocating motion of the filter screen 11 can be flexibly adjusted to adapt to different water qualities and filtration requirements.

[0028] In a further preferred embodiment of the present invention, a scraper 18 is rotatably mounted on the activated carbon filter plate 4, and a protective cover 19 is fixedly mounted on the activated carbon filter plate 4, with a driving mechanism provided inside the protective cover 19.

[0029] In this embodiment, the scraper 18 is designed to help remove impurities and blockages adhering to the surface of the activated carbon filter plate 4, keeping its filter pores unobstructed and thus improving filtration efficiency. The protective cover 19 is used to cover the scraper 18 and the drive mechanism, preventing wastewater from splashing directly onto the scraper 18 and drive mechanism, causing damage or contamination. Simultaneously, the protective cover 19 also provides some sound insulation and dust protection, improving the working environment and reliability of the equipment. The drive mechanism provides sufficient driving force to scrape the surface of the activated carbon filter plate 4 with the scraper 18. Regularly scraping the surface of the activated carbon filter plate 4 reduces the accumulation of impurities and blockages, extending the service life of the activated carbon filter plate 4. The design of the scraper 18 and drive mechanism allows users to easily maintain and clean them, keeping the equipment in good working condition.

[0030] In a further preferred embodiment of the present invention, the driving mechanism includes a first bevel gear 20, a rotating rod 21, and a second bevel gear 22. The first bevel gear 20 is fixedly mounted on the central shaft of the scraper 18. The rotating rod 21 is rotatably mounted on the protective cover 19. The other end of the rotating rod 21 extends to the outside of the filter box 1. The second bevel gear 22 is fixedly mounted on the rotating rod 21 and meshes with the first bevel gear 20.

[0031] In this embodiment, the first bevel gear 20 serves as the driving component for the rotation of the scraper 18. The design of the first bevel gear 20 allows it to mesh with the second bevel gear 22, thereby transmitting rotational power. The rotating rod 21, as a transmission component, transmits the externally input rotational power to the second bevel gear 22, thus driving the scraper 18 to rotate. The design of the second bevel gear 22 allows it to receive the rotational power transmitted by the rotating rod 21 and convert it into rotational power for the scraper 18. Through the meshing transmission of the first bevel gear 20 and the second bevel gear 22, efficient conversion of the external rotational power of the rotating rod 21 to the internal rotational power of the scraper 18 is achieved, ensuring the stable rotation of the scraper 18. The bevel gear transmission method makes the overall structure of the drive mechanism more compact, saving space, while improving the stability and reliability of the equipment. The rotating rod 21 is easy for the user to manually drive, and also facilitates the maintenance and cleaning of the drive mechanism.

[0032] In a further preferred embodiment of the present invention, an operating block is fixedly installed at one end of the rotating rod 21 extending outside the filter box 1, and a support block 23 is fixedly installed on the activated carbon filter plate 4, the support block 23 being rotatably connected to the rotating rod 21.

[0033] In this embodiment, the design of the operating block allows users to easily and manually rotate the rotating rod 21, thereby driving the scraper 18 to rotate, ensuring comfortable and stable operation. The design of the support block 23 provides a stable support point for the rotating rod 21, ensuring the stability and reliability of the rotating rod 21 during rotation and extending the service life of the equipment. The design of the operating block allows users to easily and manually operate the rotating rod 21, thereby driving the scraper 18 to rotate for cleaning and maintenance of the activated carbon filter plate. This improves the ease of operation and practicality of the equipment. The rotational connection between the support block 23 and the rotating rod 21 reduces friction and wear during rotation, extending the service life of the equipment.

[0034] In summary, compared with related technologies, this device, through its multi-layered filtration structure design, including a filter bucket, filter screen, and activated carbon filter plate, effectively removes large particulate impurities, fine impurities, and harmful substances from wastewater, thus improving effluent quality. Simultaneously, the reciprocating mechanism allows the filter screen to move back and forth during the filtration process, preventing impurities from clogging the mesh and further improving filtration efficiency. Furthermore, the design of the scraper and drive mechanism allows users to easily clean and maintain the activated carbon filter plate, extending its service life. The overall structure is compact and rational, improving wastewater treatment efficiency and quality, and facilitating the recycling of water resources.
