Description

Technical Field

[0001] This invention relates to a structure for collecting and removing strongly adhering impurities and a self-cleaning filtration system. It belongs to the field of water treatment technology and specifically relates to a structure for collecting and removing strongly adhering impurities that is installed on a self-cleaning filtration system. Under the sealed conditions of the sealed structure, the structure can efficiently collect and clean impurities, thereby achieving a cleaning effect on impurities with strong adhesion to the filter screen. Background Technology

[0002] In water treatment, filters play a crucial role in separating impurities and purifying water. With prolonged use, a large amount of suspended solids, particles, colloids, and other impurities continuously adhere to the filter surface and pores, causing clogging, increased water flow resistance, and decreased filtration efficiency. Failure to clean them promptly will affect the output and quality of water treatment. Currently, common methods for cleaning water treatment filters include manual disassembly and cleaning, and mechanical rinsing of fixed structures. Manual disassembly and cleaning requires removing the filter from the equipment while the machine is stopped, using specialized tools to brush and rinse the filter, and then allowing it to air dry completely. The process involves reinstalling the filter screen back into the equipment. Manual disassembly and cleaning requires a lot of manpower and time, and frequent disassembly can easily damage the filter screen and affect its service life. Fixed mechanical flushing involves installing fixed flushing nozzles near the water treatment filter screen. The nozzles spray high-pressure water onto the filter screen surface to wash away impurities. Although fixed mechanical flushing can achieve a certain degree of automated cleaning, it can usually only clean a single area of ​​the filter screen surface and cannot fully cover all areas of the filter screen, resulting in poor cleaning effect. Residual impurities will still affect the filtration efficiency of the filter screen and the quality of water treatment.

[0003] CN119263470A discloses a wastewater treatment device for printing and dyeing with a filter cleaning function. Suspended solids in the wastewater are blocked by filter strips. The rotating filter strips change their position relative to the inlet, making it easier for the suspended solids to separate from the filter strips. An outer fan plate pushes the wastewater towards the rotating shaft, and the suspended solids adhering to the filter strips move into the annular opening, leaving them in the receiving box and reducing the frequency of cleaning. However, the process of the filter strips adhering to the suspended solids and moving them into the annular opening depends on the flow of wastewater and the force of the outer fan plate pushing the wastewater. When the wastewater flow rate is low, the suspended solids may not be smoothly pushed into the receiving box, affecting the equipment's treatment efficiency and cleaning reliability.

[0004] To address the aforementioned issues, the applicant filed a separate Chinese invention patent application entitled "A Self-Cleaning Filtration System and Water Treatment Device," which achieves multi-directional dynamic cleaning of the filter screen through the synergistic effect of the collection structure and the support structure while the water pipe is in operation. However, the aforementioned self-cleaning filter screen device does not have an effective scraping structure, making it unable to efficiently clean some highly adhesive impurities.

Detailed Implementation Example 1

[0012] The present invention provides a structure for removing strongly adhering impurities, comprising a sealing structure and an aggregation structure; Its characteristic is that the agglomeration structure is placed inside the sealed structure. Under the sealed conditions of the sealed structure, the agglomeration structure efficiently agglomerates and cleans impurities, thereby achieving the cleaning effect on impurities with strong adhesion to the filter screen. The sealing structure consists of a sealing chamber (21), a collection range frame (23), and a shaped sealing block (24). The opening end of the sealing chamber (21) is close to the side of the filter screen (17). The collection range frame (23) is provided at the inner edge of the sealing chamber (21). The shaped sealing block (24) is fixedly connected to the inner wall of the first transmission pipe (6). The shaped sealing block (24) is located on the other side of the filter screen (17) corresponding to the opening end of the sealing chamber (21). Preferably, the sealing chamber (21) is generally teardrop-shaped, with the arc end close to the edge of the filter screen (17) and the tip close to the center of the filter screen (17); The aggregation structure consists of a shaped scraper (22), a collection and aggregation cylinder (25), and a telescopic tube (26). The shaped scraper (22) is generally in the shape of a wave-shaped plate. One end of the shaped scraper (22) is fixedly connected to the inner wall of the second transmission tube (10), and the other end of the shaped scraper (22) is placed inside the sealed chamber (21). The shape of the collection and aggregation cylinder (25) matches that of the sealed chamber (21). The opening end of the collection and aggregation cylinder (25) is close to the opening of the sealed chamber (21), and the other end of the collection and aggregation cylinder (25) is connected to the telescopic tube (26). Preferably, the irregular scraper (22) is a plate-like structure with a sinusoidal wave shape; Preferably, the irregularly shaped scraper (22) is in contact with the filter screen (17), and the surface of the irregularly shaped scraper (22) in contact with the filter screen (17) is made of a flexible material; When in use, when the filter screen needs to be cleaned, the filter screen (17) starts to rotate, and the irregular scraper (22) scrapes the surface of the filter screen. The scraped impurities move into the sealed chamber (21). After the impurities enter the sealed chamber (21), they accumulate in the sealed chamber (21). The impurities accumulated in the sealed chamber (21) are sucked into the collection and gathering cylinder (25) by the water pump (9) and transferred to the external collection chamber through the telescopic pipe (26) to complete the cleaning of impurities. Example 2

[0013] The difference between this embodiment and embodiment 1 is that the surface of the irregular sealing block (24) is provided with multiple anti-sticking holes (27). The anti-sticking holes (27) can break the direct contact between impurities and the surface of the irregular sealing block (24), reduce the area of ​​impurity adhesion. When water flows through, the pores of the anti-sticking holes (27) will form tiny water flow channels, generating local water flow disturbance, making it difficult for impurities to accumulate on the surface of the irregular sealing block (24), thereby effectively preventing impurities from sticking together, keeping the surface of the irregular sealing block (24) clean, and further improving the operating efficiency of the entire water treatment system. The sealing chamber (21) is generally teardrop-shaped, with the arc end close to the edge of the filter screen (17) and the tip close to the center of the filter screen (17). The arc end close to the edge of the filter screen (17) can better cover the edge area of ​​the filter screen, prevent impurities from leaking from the edge, and help to gather impurities to the center and tip of the sealing chamber, thereby improving the gathering effect of impurities. The irregular scraper (22) is designed as a plate-like structure with a sinusoidal wave shape. During the scraping process, it can cause a certain disturbance to the water flow and impurities, making it easier for the scraped impurities to flow into the sealed chamber under the drive of the water flow, which is conducive to the accumulation and collection of impurities. The irregular scraper (22) contacts the filter screen (17), and the surface of the irregular scraper (22) in contact with the filter screen (17) is designed with a flexible material. When the irregular scraper (22) contacts the filter screen (17), it can effectively avoid causing hard damage to the filter screen (17) and maintain the integrity and filtration performance of the filter screen (17). The goal is to achieve the function of cleaning impurities that are strongly adhered to the filter screen by placing the aggregation structure inside the sealed structure and efficiently collecting and cleaning the impurities under the sealed conditions of the sealed structure. It should be noted that the aforementioned structure for removing strongly adhering impurities needs to be installed in one of the following self-cleaning filtration systems. The self-cleaning filtration system includes a support structure and a collection structure; characterized in that the collection structure is placed on the support structure, and the multi-directional dynamic cleaning of the filter screen is achieved through the synergistic effect of the collection structure and the support structure. The support structure consists of a support base (1), a drive motor (2), a support plate (3), a drive gear (4), a support frame (5), a first transmission pipe (6), a drive gear (7), a second transmission pipe (10), a rotating ring (11), and a filter screen (17). Two support frames (5) are placed on the support base (1), the drive motor (2) is placed on the base (1), two support plates (3) are placed on the base (1), and the two support plates (3) are positioned between the two support frames (5). The drive gear (4) is placed between the two support plates (3), and the drive gear (4) is rotatably connected to the two support plates (3). The motor shaft of the motor (2) passes through one of the support plates (3) and is fixedly connected to the central shaft of the transmission gear (4). The first transmission pipe (6) is placed on a support frame (5), and the second transmission pipe (10) is placed on another support frame (5). A filter screen (17) is placed on the inner wall of the connection between the first transmission pipe (6) and the second transmission pipe (10). The edge of the filter screen (17) is fixedly connected to the rotating ring (11). The rotating ring (11) is rotatably connected to the first transmission pipe (6) and the second transmission pipe (10). The outer edge of the rotating ring (11) is provided with transmission gear teeth (7). The transmission gear teeth (7) mesh with the transmission gear (4). Preferably, the rotating ring (11) and the filter screen (17) are connected by an embedded connection. An annular groove is opened on the inner wall of the rotating ring (11), the edge of the filter screen (17) is embedded in the groove, and sealed with sealant. Preferably, a sealing groove is machined on the mating surface of the first transmission pipe (6) and the second transmission pipe (10) and the rotating ring (11), and the rotating ring (11) and the sealing groove are connected by a metal sealing ring. The collection structure consists of a collection pipe (8), a water pump (9), an aggregating cylinder (12), a collection chamber (13), a connecting block (14), an electric actuator (15), a telescopic transmission pipe (16), and an auxiliary absorption block (18). The water pump (9) is located on the outer wall of the second transmission pipe (10). The collection pipe (8) is U-shaped, with the water pump (9) connected to the horizontal section on the outer side of the collection pipe (8). The horizontal section on the inner side of the collection pipe (8) is connected to one end of the telescopic transmission pipe (16), and the other end of the telescopic transmission pipe (16) is connected to one end of the aggregating cylinder (12). The other end of the cylinder (12) is close to the filter screen (17). The outer wall of the collecting cylinder (12) is fixedly connected to the movable end of the electric push rod (15) through the connecting block (14). The collection chamber (13) is fixedly connected to the inner wall of the second transmission pipe (10). The telescopic transmission pipe (16), the collecting cylinder (12) and the electric push rod (15) are all located inside the collection chamber (13). The auxiliary absorption block (18) is fixedly connected to the inner wall of the first transmission pipe (6). The open ends of the auxiliary absorption block (18) and the collecting cylinder (12) are placed on both sides of the filter screen (17). Preferably, the front end of the collecting cylinder (12) is designed in the shape of a flared mouth, and the inner wall is smooth and streamlined; Preferably, the telescopic transmission tube (16) adopts a spiral nested structure, with the inner layer being a corrugated flexible tube and the outer layer being a telescopic rigid tube; This invention also relates to a cleaning method for a self-cleaning filtration system, characterized in that cleaning using the self-cleaning filtration system includes the following steps: When the filter screen (17) needs to be cleaned, the electric actuator (15) is activated, and its movable end extends, driving the collecting cylinder (12) close to the surface of the filter screen (17) through the connecting block (14). With the assistance of the auxiliary absorption block (18), a sealed space is formed between the auxiliary absorption block (18) and the collecting cylinder (12). After the water pump (9) is started, it works in conjunction with the collection pipe (8), the telescopic transmission pipe (16) and the collecting cylinder (12) to suck out the impurities and a small amount of water on the filter screen (17); Start the drive motor (2), the drive gear (4) rotates and drives the drive wheel teeth (7) to rotate, thereby driving the rotating ring (11) to rotate. The rotating ring (11) drives the filter screen (17) to rotate to the appropriate position, and cleans the other areas of the filter screen (17) again. Example 2

[0014] The difference between this embodiment and embodiment 1 is that the auxiliary absorption block (18) has a weight reduction hole (19) inside. The auxiliary absorption block (18) adopts a hollow structure. The hollow structure can effectively reduce the weight of the auxiliary absorption block (18) without affecting its function, which helps to reduce the burden on the support structure, reduce energy consumption, make the device operate more efficiently, and reduce production costs. At the same time, the hollow structure makes the auxiliary absorption block (18) have better elasticity and flexibility. During the operation of the device, the auxiliary absorption block (18) can more easily adapt to external forces, buffer and disperse the force through its own deformation, reduce the risk of damage, and improve the stability and reliability of the device. Example 3

[0015] The difference between this embodiment and embodiment 1 is that a sealing ring (20) is provided at one end of the collecting cylinder (12) near the filter screen (17). The sealing ring (20) can form a tight sealing connection between the collecting cylinder (12) and the filter screen (17), effectively preventing water or impurities from leaking out from the gap between them during the treatment process, thus improving water treatment efficiency. Moreover, through the sealing effect of the sealing ring (20), the collecting cylinder (12) can form a relatively stable sealed space near the filter screen (17), which helps to more effectively adsorb impurities on the filter screen (17) into the collecting cylinder (12), thereby improving the collection efficiency of impurities, ensuring the cleaning effect of the filter screen (17), and extending its service life. The rotating ring (11) and the filter screen (17) are connected by an embedded connection. An annular groove is opened on the inner wall of the rotating ring (11), and the edge of the filter screen (17) is embedded in the groove and sealed with sealant. This design makes the connection between the rotating ring (11) and the filter screen (17) tighter and more stable, ensuring that the two can move synchronously during rotation and that there will be no relative slippage or detachment. Sealing grooves are machined on the mating surfaces of the first transmission pipe (6) and the second transmission pipe (10) and the rotating ring (11). The rotating ring (11) and the sealing groove are connected by a metal sealing ring. The metal sealing ring can fit tightly in the sealing groove and on the surface of the rotating ring (11), effectively preventing water from leaking from the connection, ensuring the sealing performance during the water treatment process, and ensuring the normal operation of the water treatment system. At the same time, when the rotating ring (11) rotates, the metal sealing ring can follow the movement of the rotating ring well and will not generate too much resistance to the rotation of the rotating ring, thus ensuring the smoothness of the rotation. The front end of the collecting cylinder (12) is designed in the shape of a trumpet, and the inner wall is designed in a smooth streamlined shape, which can increase the water absorption range of the collecting cylinder (12) and make it easier for impurities to be sucked in. The smooth streamlined inner wall can reduce water flow resistance and allow impurities to pass through the collecting cylinder (12) more smoothly, thereby improving the impurity collection efficiency. The telescopic transmission pipe (16) adopts a nested structure, with an inner corrugated hose and an outer telescopic rigid pipe. The length can be flexibly adjusted when the collecting cylinder (12) moves. The corrugated inner hose increases the flexibility of the pipe and reduces the water flow resistance caused by bending. The outer rigid pipe provides structural support to prevent the hose from deforming excessively, ensuring smooth transmission of impurities and improving the overall operating efficiency of the device. The goal is to achieve multi-directional dynamic cleaning of the filter screen while the water pipe is in operation, through the synergistic effect of the collection and support structures.
