Description

Technical Field

[0001] This utility model relates to the field of pretreatment filtration components for pure water systems, and more particularly to an anti-clogging pretreatment filtration component for pure water systems. Background Technology

[0002] In the pure water preparation process, the pretreatment filtration component is a key link to ensure the stable operation of subsequent core equipment such as reverse osmosis and EDI, and is widely used in drinking water preparation, ultrapure water for the electronics industry, and purified water for pharmaceuticals.

[0003] Most pre-treatment filtration components for pure water systems on the market today use filter screens, filter media, and other structures to intercept impurities. They maintain filtration performance by manual disassembly and cleaning or by a built-in backwashing mechanism to deal with impurities such as silt, suspended particles, colloids, and fibers in the raw water. They are an indispensable pre-treatment device in pure water systems.

[0004] Existing anti-clogging pure water system pretreatment filtration components often face problems affecting filtration efficiency and stability during use. On the one hand, although the filter screens of existing components are nominally anti-clogging, they are still prone to clogging due to the accumulation of impurities such as sediment, colloids, and fibers during raw water filtration. Clogging requires stopping the system, disassembling the filter screen, and manual cleaning, which not only interrupts the pure water preparation process but also increases operational complexity. On the other hand, existing components cannot remove air bubbles mixed in with the water flow during raw water filtration. These air bubbles easily adhere to the filter screen surface, forming an air film that hinders effective contact between the water flow and the filter screen, reducing filtration efficiency and potentially leading to localized impurity accumulation and exacerbating clogging. Therefore, an anti-clogging pure water system pretreatment filtration component is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pretreatment filter component for a pure water system that is designed to prevent clogging. It aims to improve the problems in the prior art where the filter screen of the filter component is prone to clogging and requires shutdown for disassembly and cleaning, and where it is impossible to remove air bubbles from the raw water filter, and the air bubbles can easily aggravate the clogging.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a pretreatment filtration component for an anti-clogging pure water system, comprising a component housing, a top cover fixedly connected to the top outer wall of the component housing via a flange, a motor fixedly connected to the top outer wall of the top cover, a rotating shaft fixedly connected to the output end of the motor, a stirring blade fixedly connected to the outer wall of the rotating shaft, a brush provided on the outer wall of the stirring blade, a scraper fixedly connected to the outer wall of the stirring blade, a filter inner shell fixedly connected to the inner wall of the component housing, a water outlet pipe fixedly connected to the bottom outer wall of the filter inner shell, a water inlet fixedly connected to the inner wall of the top cover, a filter plate fixedly connected to the top inner wall of the filter inner shell, a sludge collection tank fixedly connected to the bottom outer wall of the filter inner shell, a drain outlet provided on the bottom outer wall of the sludge collection tank, and an ultrasonic transmitter fixedly connected to the top inner wall of the top cover.

[0007] As a further description of the above technical solution: An air inlet pipe is fixedly connected to the inner wall of the filter housing.

[0008] As a further description of the above technical solution: The outer walls of the brush and scraper are fitted to the inner filter shell.

[0009] As a further description of the above technical solution: The intake pipe is equipped with a one-way valve.

[0010] As a further description of the above technical solution: The scrapers are provided in two sets, and the two sets of scrapers are symmetrically arranged on the outer wall of the stirring blade.

[0011] As a further description of the above technical solution: The top and bottom outer walls of the stirring blades are also equipped with brushes, and their outer walls are in contact with the two sets of filter plates.

[0012] This utility model has the following beneficial effects: 1. In this utility model, by setting a brush and a scraper inside the component, the sticky substances and fibrous impurities attached to the surface of the filter screen and the inner wall of the filter shell can be physically scraped and cleaned in real time; at the same time, with the ultrasonic transmitter, the air bubbles generated during the raw water filtration can be efficiently eliminated, preventing the air bubbles from forming an air film that obstructs the water flow and accelerating the speed at which the water flows through the inner shell of the filter. This reduces the frequency of stopping to disassemble and clean the filter screen and improves the overall filtration efficiency.

[0013] 2. In this utility model, by setting an air inlet pipe and connecting it to an air pump, airflow can be introduced into the raw water to achieve aeration. The continuous airflow generated during the aeration process will impact the filter plate and the inner wall of the filter shell, helping to flush away the attached stubborn impurities. This complements the physical cleaning of the brush and scraper, further reducing the probability of impurities clogging the filter screen, improving the overall anti-clogging ability of the component, and reducing manual maintenance costs.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Reference Figures 1-3This utility model provides an embodiment of a pretreatment filtration component for an anti-clogging pure water system, comprising a component housing 1, which provides external protection and a mounting base for the entire component. A top cover 2 is fixedly connected to the top outer wall of the component housing 1 via a flange. The top cover 2 seals the top of the component and provides a mounting carrier for the upper components. A motor 3 is fixedly connected to the top outer wall of the top cover 2, providing a power source for the internal cleaning structure of the component. A rotating shaft 4 is fixedly connected to the output end of the motor 3, transmitting the power of the motor 3 to the lower cleaning components. The outer wall of the rotating shaft 4... A stirring blade 11 is fixedly connected to the filter, which can drive the brush 12 and scraper 13 to move synchronously. The outer wall of the stirring blade 11 is provided with a brush 12, which is used to clean the filter screen and the inner wall of the housing. A scraper 13 is fixedly connected to the outer wall of the stirring blade 11, which is used to scrape off the sticky or fibrous impurities attached to the inner wall of the housing. Two sets of scrapers 13 are provided, which are symmetrically arranged on the outer wall of the stirring blade 11 to achieve a thorough cleaning of the inner wall of the filter inner housing 15. The outer walls of the brush 12 and scraper 13 are in close contact with the filter inner housing 15 to ensure that there are no dead corners in the cleaning.

[0018] Reference Figures 2-4 The top and bottom outer walls of the stirring blade 11 are also equipped with brushes 12, whose outer walls are in contact with the two sets of filter plates 14, which can simultaneously clean impurities on the surface of the filter plates 14. The inner wall of the component housing 1 is fixedly connected to the filter inner shell 15, which is used to carry the raw water filtration process. The bottom outer wall of the filter inner shell 15 is fixedly connected to the water outlet pipe 8, which is used to discharge the filtered clean water. The inner wall of the top cover 2 is fixedly connected to the water inlet 10, which is used to introduce raw water into the component. The top inner wall of the filter inner shell 15 is also fixedly connected to the filter inner shell 15. A filter plate 14 is fixedly connected to the filter housing 15. The filter plate 14 is used to intercept and filter impurities in the raw water. A sludge collection tank 5 is fixedly connected to the bottom outer wall of the filter housing 15. The sludge collection tank 5 is used to collect impurities that fall off during the cleaning process and the wastewater generated. A drain outlet 6 is opened on the bottom outer wall of the sludge collection tank 5. The drain outlet 6 is used to discharge the wastewater and impurities collected in the sludge collection tank 5 into the assembly. An ultrasonic transmitter 9 is fixedly connected to the top inner wall of the top cover 2. The ultrasonic transmitter 9 is used to eliminate air bubbles generated during the raw water filtration and accelerate the filtration efficiency. Reference Figures 1-3 An air inlet pipe 7 is fixedly connected to the inner wall of the filter inner shell 15. The air inlet pipe 7 is used to introduce the gas generated by the air pump into the filter inner shell 15. A one-way valve is installed inside the air inlet pipe 7. The one-way valve can prevent the raw water or impurities in the filter inner shell 15 from flowing back into the air inlet pipe 7.

[0019] Working Principle: When the pretreatment filtration component of this anti-clogging pure water system is working, raw water is first introduced into the filter inner shell 15 through the inlet 10 on the inner wall of the top cover 2. The filter inner shell 15 carries the raw water filtration process. After entering, the raw water first contacts the filter plate 14 on the top inner wall of the filter inner shell 15. The filter plate 14 intercepts and filters impurities in the raw water. At the same time, the motor 3 on the top outer wall of the top cover 2 starts. The motor 3, as a power source, drives the rotating shaft 4 at the output end to rotate. The rotating shaft 4 transmits power to the stirring blades 11 on the outer wall, causing the stirring blades 11 to rotate synchronously. The brush 12 on the outer wall of the stirring blades 11 and the two sets of symmetrically arranged scrapers 13 move with the stirring blades 11. The outer walls of the brush 12 and the scrapers 13 are in contact with the filter inner shell 15. The scrapers 13 scrape off the sticky or fibrous impurities attached to the inner wall of the filter inner shell 15, and the brush 12 cleans the inner wall of the filter inner shell 15. The ultrasonic transmitter 9 on the inner wall of the top cover 2 is activated to remove small impurities on the surface of the filter plate 14. During this process, the ultrasonic transmitter 9 on the inner wall of the top cover 2 is activated to eliminate air bubbles generated during the raw water filtration, preventing air bubbles from obstructing the water flow and contacting the filter plate 14, thus accelerating the filtration efficiency. At the same time, the air inlet pipe 7 on the inner wall of the filter inner shell 15 introduces the gas generated by the air pump into the filter inner shell 15. The airflow generated by the oxygen explosion helps to clean the impurities attached to the filter plate 14 and the filter inner shell 15. The one-way valve inside the air inlet pipe 7 prevents the raw water or impurities in the filter inner shell 15 from flowing back into the air inlet pipe 7. The impurities that fall off during the cleaning process and the wastewater generated fall into the dirt collection tank 5 on the bottom outer wall of the filter inner shell 15, and are then discharged from the component through the drain port 6 on the bottom outer wall of the dirt collection tank 5. The clean water filtered by the filter plate 14 is discharged through the water outlet pipe 8 on the bottom outer wall of the filter inner shell 15, completing the entire pretreatment filtration work.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
