Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a novel filtration component for wastewater treatment equipment. Background Technology

[0002] In the field of wastewater treatment, filtration components are the core components for achieving solid-liquid separation of wastewater, and their filtration efficiency and stability directly affect the overall operation of the wastewater treatment system. Currently, most mainstream wastewater treatment filtration components on the market adopt a fixed filter cartridge structure, where wastewater passes through filter holes on the side wall of the cartridge to trap impurities. However, the following key issues exist in practical applications:

[0003] Easy clogging leads to decreased filtration efficiency: Flocculent impurities and suspended particles in sewage easily adhere to the inner wall of the filter cartridge and the surface of the filter holes. As the filtration time increases, the filter holes are gradually clogged, the resistance to sewage flow increases, the filtration efficiency is significantly reduced, and frequent shutdowns are required to disassemble the filter cartridge for cleaning, which seriously affects the continuity of sewage treatment.

[0004] Poor adaptability to large debris: Some industrial or domestic sewage may contain large solid impurities (such as fiber clumps, fragments, etc.). These impurities cannot pass through the filter holes and are easily stuck in the inner cavity of the filter cartridge or block the filter hole inlet. This not only further aggravates the clogging problem, but may also cause the material feeding parts to jam and damage the core structure of the equipment.

[0005] Cleaning and maintenance are cumbersome and incomplete: Existing cleaning methods for filter components mostly involve scraping with a single scraper or rinsing with high-pressure water. A single scraper is difficult to remove stubborn impurities, while high-pressure rinsing can easily cause impurities to re-adhere to the inner wall of the filter cartridge, resulting in limited cleaning effect. At the same time, after cleaning, the impurities need to be removed from the filter cartridge to be discharged, making the maintenance process complicated, time-consuming, and labor-intensive, increasing labor and time costs.

[0006] In view of the shortcomings of the existing technology, there is an urgent need for a new type of filter component that combines high-efficiency filtration, anti-clogging, easy cleaning and automatic adaptation capabilities, so as to solve the operational pain points of existing equipment and improve the stability and economy of wastewater treatment system.

[0007] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content

[0008] The present invention adopts the following technical solution:

[0009] A novel filtration assembly for a wastewater treatment device includes a tank, a filter cylinder installed inside the tank, a feeding assembly installed inside the filter cylinder, and a drive assembly installed on the tank. The bottom outer periphery of the filter cylinder is connected to the inner wall of the tank, forming a cavity between the tank and the filter cylinder. The side wall of the filter cylinder has filter holes for communicating with the inner cavity of the filter cylinder and the cavity.

[0010] The side of the tank is provided with a first communication port that communicates with the inner cavity of the filter cylinder and a second communication port that communicates with the partition cavity;

[0011] The material dispensing assembly includes a rotating shaft installed at the center of the inner cavity of the filter cylinder, two dispensing plates installed on the outer periphery of the rotating shaft for rotating with the rotating shaft, a brush installed on the side of one of the dispensing plates and in contact with the inner wall of the filter cylinder, and a scraper installed on the side of the other dispensing plate and in contact with the side wall of the filter cylinder.

[0012] The drive assembly is connected to the rotating shaft and is used to drive the rotating shaft to rotate.

[0013] Preferably, the outer periphery of the rotating shaft is provided with a cutter for rotating with the rotating shaft to cut debris.

[0014] Preferably, the bottom of the tank is provided with a third communication port that communicates with the inner cavity of the filter cylinder.

[0015] Preferably, the first connection port, the second connection port, and the third connection port are all equipped with solenoid valves.

[0016] Preferably, the drive assembly includes a drive motor connected to the rotating shaft for driving the rotating shaft to rotate.

[0017] Preferably, the upper outer periphery of the filter cylinder is provided with an annular mounting block; the annular mounting block is provided with an annular water channel; the bottom of the annular mounting block is connected to the annular water channel, and multiple nozzles are used to clean the side wall of the filter cylinder; the side of the tank is provided with a water inlet pipe that communicates with the annular water channel.

[0018] This utility model relates to a novel filter assembly for water treatment equipment. When the liquid-dispensing plate of the material-dispensing assembly rotates with the rotating shaft, it drives the wastewater inside the filter cylinder to rotate, generating centrifugal force and accelerating the wastewater's entry into the diaphragm through the filter holes. Compared to traditional gravity filtration, the filtration speed is increased by 30%-50%. Simultaneously, the brush and scraper clean the inner wall of the filter cylinder in real time, effectively preventing impurities from adhering and clogging the filter holes, ensuring long-term stable filtration efficiency and avoiding frequent shutdowns due to clogging. The cutter on the outer periphery of the rotating shaft can cut large debris (such as fiber clumps and fragments) in the wastewater into small particles, preventing large debris from clogging the filter holes or jamming the material-dispensing assembly. This allows the assembly to be adapted to wastewater containing impurities of different particle sizes (such as industrial wastewater and domestic sewage), expanding its application scenarios. The annular water channel of the ring mounting block, in conjunction with multiple nozzles, allows for all-around rinsing of the filter cylinder sidewalls after the introduction of clean water. Combined with the mechanical cleaning of the brush and scraper, this forms a "rinsing and scraping" process. The dual cleaning mode improves the thoroughness of cleaning; at the same time, the third connection port can directly discharge impurities after cleaning or filter residue without disassembling the filter cartridge, shortening maintenance time and reducing labor and equipment wear and tear costs.

[0019] The solenoid valves in the first, second, and third connecting ports can be linked with the control system of the sewage treatment system to realize the automatic switching of the inlet, outlet, sludge discharge, and cleaning processes (such as opening the first and second connecting ports during filtration, and closing the first two and opening the third connecting port during cleaning), reducing manual intervention, adapting to large-scale automated sewage treatment production lines, and improving the overall system operating efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0026] Please see Figures 1 to 3 A novel filter assembly for a wastewater treatment device includes a tank 10, a filter cartridge 20 installed inside the tank 10, a material feeding assembly 30 installed inside the filter cartridge 20, and a drive assembly 40 installed on the tank 10.

[0027] The bottom outer periphery of the filter cylinder 20 is connected to the inner wall of the tank 10, so that a cavity 101 is formed between the tank 10 and the filter cylinder 20; the side wall of the filter cylinder 20 is provided with filter holes 201 for connecting the inner cavity of the filter cylinder 20 and the cavity 101.

[0028] The side of the tank body 10 is provided with a first communication port 102 that communicates with the inner cavity of the filter cylinder 20 and a second communication port 103 that communicates with the partition cavity 101.

[0029] The material feeding assembly 30 includes a rotating shaft 301 installed at the center of the inner cavity of the filter cylinder 20, two liquid feeding plates 302 installed on the outer periphery of the rotating shaft 301 for rotating with the rotating shaft 301, a brush 303 installed on the side of one of the liquid feeding plates 302 and in contact with the inner wall of the filter cylinder 20, and a scraper 304 installed on the side of the other liquid feeding plate 302 and in contact with the side wall of the filter cylinder 20.

[0030] The drive assembly 40 is connected to the rotating shaft 301 and is used to drive the rotating shaft 301 to rotate.

[0031] Specifically, in this embodiment, during operation, wastewater enters the inner cavity of the filter cylinder 20 through the first connecting port 102, then passes through the filter holes 201 and enters the partition cavity 101, finally exiting through the second connecting port 103. Simultaneously, the drive assembly 40 drives the rotating shaft 301 to rotate, causing the rotating shaft 301 to drive the liquid-dispensing plate 302 to rotate, thereby causing the wastewater entering the inner cavity of the filter cylinder to rotate and quickly pass through the filter holes 201 into the partition cavity 101 under the influence of centrifugal force. At the same time, the scraper 304 scrapes the inner wall of the filter cylinder 20 as it rotates with the liquid-dispensing plate 302, preventing impurities in the wastewater from adhering to the side wall of the filter cylinder 20 during stirring and centrifugation, thus clogging the filter cylinder 20 and improving the filtration effect and efficiency. In addition, the brush 303 cleans the side wall of the filter cylinder 20 as it rotates with the rotating shaft 301, improving the cleanliness of the filter cylinder 20. In this embodiment, the structural design of "liquid-dispensing plate 302 and rotating shaft 301" utilizes centrifugal force to accelerate wastewater filtration, breaking through the efficiency bottleneck of traditional gravity filtration, increasing the speed at which wastewater passes through the filter holes, and shortening the single filtration cycle. At the same time, the brush and scraper clean the inner wall of the filter cylinder in real time from two dimensions: "flexible cleaning" (brush removes small attached impurities) and "rigid scraping" (scraper removes stubborn impurities), solving the problem of filter hole blockage from the source and ensuring a continuous and stable filtration process.

[0032] In one embodiment, the outer periphery of the rotating shaft 301 is provided with a cutter 305 for rotating with the rotating shaft 301 to cut debris. In this embodiment, for large debris (such as fiber clumps and fragments) in sewage, the cutter can cut them into small particles as the rotating shaft rotates, so that the small particles of impurities can be intercepted by the centrifugal force of the liquid-dispersing plate or flow with the sewage, avoiding large debris from getting stuck in the inner cavity of the filter cylinder or blocking the filter hole inlet, and preventing the material dispersing component from getting stuck and damaged; at the same time, the cut small particles of impurities are more easily intercepted by the filter holes and are less likely to form "bridging" blockage (large debris is prone to forming bridges at the filter hole inlet, blocking the flow of sewage), further improving the flowability of the filter holes; expanding the adaptability of the device to sewage, so that the component can not only treat domestic sewage with small impurity particle size, but also adapt to industrial wastewater containing large impurities, improving the versatility of the component.

[0033] In one embodiment, the bottom of the tank 10 is provided with a third connecting port 104 that communicates with the inner cavity of the filter cylinder 20. The third connecting port 104 effectively discharges impurities from the inner cavity of the filter cylinder 20 after filtration. Furthermore, solenoid valves (not shown in the figure) are provided in the first connecting port 102, the second connecting port 103, and the third connecting port 104. In this embodiment, after filtration, residual impurities in the inner cavity of the filter cylinder can be directly discharged through the third connecting port without disassembling the filter cylinder, thus solving the cumbersome process of "disassembling the cylinder to discharge slag" in traditional components. During cleaning, impurities cleaned by the brush and scraper, as well as wastewater from the spray nozzle, can be quickly discharged from the tank through the third connecting port, preventing impurities from accumulating in the inner cavity of the filter cylinder and ensuring thorough cleaning. The third connecting port is located at the bottom of the tank, utilizing gravity to assist in slag discharge, eliminating the need for additional power to drive impurity discharge, reducing energy consumption, and ensuring more thorough slag discharge, thus reducing secondary pollution caused by residual impurities.

[0034] In one embodiment, the drive assembly 40 includes a drive motor 401 connected to the rotating shaft 301 for driving the rotating shaft 301 to rotate. The drive motor 401 provides stable power output and can continuously provide a constant torque to the rotating shaft, ensuring that the liquid-dispensing plate, brush, scraper, and cutter (if present) operate synchronously and stably, avoiding problems such as weakened centrifugal force and incomplete cleaning due to insufficient power;

[0035] In one embodiment, the upper outer periphery of the filter cylinder 20 is provided with an annular mounting block 50; the annular mounting block 50 is provided with an annular water channel 501; the bottom of the annular mounting block 50 is connected to the annular water channel 501, and multiple nozzles 503 are used to clean the side wall of the filter cylinder 20; the side of the tank body 10 is provided with a water inlet pipe 502 connected to the annular water channel 501. In this embodiment, during operation, when the filter cylinder 20 needs to be cleaned, the first connecting port 102 and the second connecting port 103 are closed under the drive of the solenoid valve. At this time, the drive assembly 40 drives the rotating shaft 301 to rotate, and the water inlet connects to the annular water channel 501, which is then sprayed out through the multiple nozzles 503. This clean water assists the brush 303 and scraper 304 in cleaning the filter cylinder 20, and the cleaned wastewater is discharged from the third connecting port 104. In this embodiment, the annular water channel 501 can evenly distribute the clean water introduced by the inlet pipe 502 to multiple nozzles 503, achieving all-round rinsing of the filter cartridge sidewall, avoiding the problem of "rinsing dead corners" in traditional single nozzles, and ensuring that every area of ​​the filter cartridge sidewall can be cleaned; at the same time, the rinsing of the nozzles 503, the brush 303, and the scraper 304 form a synergistic effect of "hydraulic rinsing + mechanical cleaning": the rinsing water can soften stubborn attached impurities, making them easier to scrape off by the scraper, while rinsing away the fine impurities cleaned by the brush, improving the cleaning effect and increasing the cleanliness of the filter cartridge inner wall by more than 60%; in addition, the cleaning process does not require disassembly of any parts and can be completed inside the tank 10. Combined with the slag discharge through the third connecting port, an integrated "cleaning-slag discharge" process is formed, further reducing maintenance steps and reducing maintenance difficulty; regular cleaning through the nozzles 503 can reduce the corrosion of the filter cartridge inner wall by impurities (some sewage impurities contain corrosive components, which can easily damage the filter cartridge if they adhere for a long time), extend the service life of the filter cartridge, and reduce equipment replacement costs.

[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
