Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage engineering technology, specifically to a filtration device for water supply and drainage. Background Technology

[0002] Water supply and drainage systems are an indispensable part of modern buildings, urban infrastructure, and industrial production. They mainly consist of two parts: water supply systems and drainage systems. The drainage system requires filtration devices to effectively remove solid impurities, particles, and other harmful substances from wastewater, thus preventing damage to pipes and other equipment and ensuring the normal operation of subsequent treatment devices.

[0003] However, the filter screens in the filtration devices of general water supply and drainage systems will become clogged after working for a long time, affecting normal drainage and reducing the quality and efficiency of filtration. If the filter screens are replaced frequently, the labor intensity will increase and the economy will be poor.

[0004] Therefore, in order to address the above problems, a filtration device for water supply and drainage is proposed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a filtration device for water supply and drainage. This invention can improve the filtration quality and efficiency of filtration devices in water supply and drainage systems, and does not require frequent filter replacement, thus offering good economic benefits.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A water supply and drainage filtration device includes a housing. An inlet and an outlet are respectively opened through the side plates on both sides of the housing. A straight guide rail is provided on the side plate between the inlet and the outlet inside the housing. The upper and lower ends of the straight guide rail contact the upper and lower side plates of the housing. A filter plate assembly is slidably connected to the straight guide rail. The filter plate assembly slides along the length of the straight guide rail. A lifting component is connected to the filter plate assembly. The lifting component is set on a support plate. The support plate is horizontally set in the middle of the housing on one side of the straight guide rail. A limiting groove is provided on the side of the support plate near the straight guide rail.

[0008] Preferably, the filter plate assembly includes a slide bar, which is slidably mounted on a straight guide rail. A filter plate frame is mounted on the slide bar, and a filter screen is mounted inside the filter plate frame.

[0009] Preferably, the lifting assembly includes a connecting rope, one end of which is connected to a slide bar, and the other end of which is mounted on a rotating wheel. The rotating wheel is coaxially mounted on the output shaft of the power component, which drives the slide bar to slide along the length of the straight guide rail and makes the filter screen contact the cleaning assembly.

[0010] Preferably, the cleaning assembly includes a cleaning brush plate, which is disposed in a limiting groove. Bristles are provided on the side of the cleaning brush plate near the filter plate, and the coverage area of ​​the bristles is not less than the area of ​​the filter screen. The upper end of the cleaning brush plate passes through the top of the housing and is connected to a first connecting plate. A first handle is provided on the side of the first connecting plate away from the cleaning brush plate.

[0011] Preferably, a limiting plate is provided at the bottom of the housing, and a through groove is opened through the limiting plate. The bottom of the filter plate frame passes through the bottom plate of the housing and is connected to a second connecting plate. The second connecting plate is set in the through groove. A sealing strip is provided at the connection between the filter plate frame and the housing. A stop block is detachably installed at the opening of the through groove to prevent the filter plate frame from falling off.

[0012] Preferably, the cavity on the side of the straight guide rail near the water inlet is a filter chamber. A connection window is opened through the side plate of the filter chamber. The side of the connection window is stepped. A baffle is installed at the connection window. A sealing strip is installed at the connection between the baffle and the side of the connection window.

[0013] Preferably, an inspection port is provided on the housing side plate on the upper side of the support plate, and a dustproof plate can be detachably inserted at the inspection port. The dustproof plate is used to isolate the lifting assembly from the external environment.

[0014] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages:

[0015] This invention incorporates a lifting component and a cleaning component. The lifting component moves the filter plate assembly up and down, bringing the filter screen of the filter plate assembly into contact with the bristles on the cleaning brush plate of the cleaning component. The relative movement between the filter screen and the bristles allows the bristles to scrub the filter screen, removing impurities and preventing clogging of the filter pores, thus improving filtration quality and efficiency. A support plate and a cleaning brush plate separate the power component from the filter chamber, preventing water from affecting its operation, and a dustproof plate facilitates maintenance of the power component.

[0022] 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.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A water supply and drainage filtration device includes a housing 1, which is a hollow cubic shell. An inlet 11 and an outlet 12 are respectively provided through the side plates on both sides of the housing 1. Straight guide rails 2 are symmetrically arranged on the side plates between the inlet 11 and the outlet 12 inside the housing 1. The upper and lower ends of the straight guide rails 2 contact the upper and lower side plates of the housing 1, respectively. A filter plate assembly is slidably connected to the straight guide rails 2, and the filter plate assembly can slide along the length of the straight guide rails 2. A lifting component is connected to the filter plate assembly, and the lifting component is mounted on a support plate 9. The support plate 9 is horizontally positioned in the middle of the housing 1 on the side of the straight guide rails near the outlet 12. A limiting groove 10 is provided on the side of the support plate 9 near the straight guide rails 2, and a cleaning component is installed within the limiting groove 10. The lifting component can move the filter plate assembly and contact the cleaning component, allowing the cleaning component to clean the filter plate assembly.

[0025] In an optional embodiment, the filter plate assembly includes a slide bar 3, which is slidably disposed on a straight guide rail 2. Specifically, T-shaped grooves are formed along the length direction on both sides of the straight guide rail 2, and the slide bar 3 is slidably engaged in the T-shaped grooves. A filter plate frame 4 is connected between the slide bars 3 on both sides of the straight guide rail 2, and a filter screen 5 is disposed in the middle of the filter plate frame 4. Preferably, the filter screen 5 is made of metal, and more preferably stainless steel, to avoid rust and other phenomena during long-term use, and at the same time extend the service life of the device.

[0026] In an optional embodiment, the lifting assembly includes a connecting rope 6, which is made of steel wire rope. One end of the connecting rope 6 is connected to a slide bar 3, and the other end of the connecting rope 6 is mounted on a rotating wheel 7. The rotating wheel 7 is coaxially mounted on the output shaft of the power component 21. The power component 21 is a motor, which drives the slide bar 3 to slide along the length of the straight guide rail 2, so that the filter screen 5 contacts the cleaning component. Preferably, the power component 21 is a dual-output shaft motor, and each of the two output ends of the dual-output shaft motor is coaxially mounted on a rotating wheel 7. The connecting rope 6 is wound on the rotating wheel 7, and the other end of the connecting rope 6 is connected to the slide bar 3 in the straight guide rail 2 on both side plates, so as to drive the slide bar 3 to move simultaneously, so that the left and right sides of the filter plate frame 4 move simultaneously, thereby improving the stability of the device.

[0027] In an optional embodiment, the cleaning assembly includes a cleaning brush plate 8, which is disposed within a limiting groove 10. Bristles are provided on the side of the cleaning brush plate 8 closest to the filter plate. The bristles are preferably made of a relatively hard material, such as polypropylene, injected nylon filaments, or glass fiber. The overall coverage area of ​​the bristles is not less than the coverage area of ​​the filter screen 5, allowing for scraping and cleaning of the filter screen 5. This prevents clogging of the filter screen 5 and extends its service life. The upper end of the cleaning brush plate 8 penetrates the top of the housing 1 and connects to a first connecting plate 14. A first handle is provided on the side of the first connecting plate 14 away from the cleaning brush plate 8. The cleaning brush plate 8 can be pulled out of the limiting groove 10 using the first handle, facilitating replacement and improving replacement efficiency.

[0028] In one optional embodiment, a limiting plate is provided at the bottom outer side of the housing 1, and a through groove 15 is formed through the limiting plate. A second connecting plate 16 is provided at the bottom of the filter plate frame 4 after penetrating the bottom side plate of the housing 1. The second connecting plate 16 is located in the through groove 15 and can move with the filter plate frame 4. A second handle is provided on the side of the second connecting plate 16 away from the filter plate frame 4 for easy handling. A sealing strip is provided at the connection between the filter plate frame 4 and the housing 1 to prevent water leakage during use. A stop block 22 is detachably provided at the lower opening of the through groove 15 by screws to prevent the filter plate frame 4 from falling off. In another preferred embodiment, a return spring is provided between the second connecting plate 16 and the stop block 22. The return spring is used to reset the filter plate frame 4 after it is pulled up by the lifting component and to make the sealing strip re-seal the housing 1, thereby improving the practicality of the device.

[0029] In an optional embodiment, a collection box is also provided at the bottom of the limiting plate to collect impurities and particles that may fall from the channel 15 and water that has not been completely discharged when the cleaning brush plate 8 brushes the filter screen 5, so as to avoid adverse effects on the external environment and improve the practicality of the device.

[0030] In an optional embodiment, the straight guide rail 2 is inclined towards the inlet 11 at an angle between 70° and 90°. In this embodiment, an 80° inclination is used, which makes it less likely for impurities in the wastewater to get stuck on the filter screen 5. Correspondingly, the cleaning brush plate 8 is also inclined, so that the surface of the cleaning brush plate 8 is parallel to the plane of the filter screen 5, and the bristles can contact the surface of the filter screen 5 near the cleaning brush plate 8. This makes it easier for impurities on the filter screen 5 to fall naturally to the bottom of the housing 1 when the brush cleans the filter screen 5, thus improving the practicality of the device.

[0031] In an optional embodiment, the cavity on the side of the straight guide rail 2 near the inlet 11 is a filter chamber 17. A connection window 18 is opened through the side plate of the filter chamber 17. The side of the connection window 18 is set as a stepped platform 19. A stopper 20 is set at the connection window 18. A sealing strip is set at the connection between the stopper 20 and the side of the connection window 18. The stopper 20 is detachably set on the connection window 18 by screws. When the connection window 18 is opened, the impurities filtered in the filter chamber 17 can be taken out, so as to avoid excessive accumulation of impurities affecting the quality and efficiency of filtration.

[0032] In an optional embodiment, the upper end of the filter plate frame 4 is flush with the height of the support plate 9 to isolate the filter chamber 17 from the upper cavity of the support plate 9, preventing water from entering the power component 21 and improving the safety of the device.

[0033] In an optional embodiment, an inspection port is provided on the side plate of the housing 1 on the upper side of the support plate 9. A dustproof plate 13 is detachably embedded in the inspection port. A third handle is provided on the outside of the dustproof plate 13 for easy access. The dustproof plate 13 is used to isolate the lifting assembly from the external environment to prevent dust from the external environment from entering the power component 21 and affecting the operation of the power component 21. At the same time, the detachable dustproof plate 13 facilitates the maintenance of the lifting assembly, thereby improving the service life and safety of the device.

[0034] Working principle: First, connect the inlet 11 of the device to the outlet 12 of the water supply and drainage system. Wastewater enters the filter chamber 17 of the device and is filtered through the filter screen 5, retaining impurities in the filter chamber 17. When the filtration rate decreases, it indicates that the filter screen 5 is clogged with impurities and needs to be cleaned. Then, stop the water intake at the inlet 11. After all or almost all the water in the filter chamber 17 is discharged through the outlet 12 of the device, start the power component 21 of the lifting assembly to rotate forward, driving the filter plate frame 4 to move upward and causing the filter screen 5 and the brush bristles to move relative to each other. This allows the brush bristles to scrub the filter screen 5, cleaning away the impurities clogging it. This allows the output end of the power component 21 to rotate in reverse. The device can be rotated in both directions to allow the brush bristles to repeatedly scrub the filter screen 5. When the output end of the power component 21 is reversed, the filter plate frame 4 moves downward under the action of gravity or the tension of the return spring, thus achieving the effect of multiple scrubbing and returning to the initial position, improving the practicality of the device. After the filter plate frame 4 returns to the initial position, water continues to enter through the device inlet 11 to continue filtration. The power component 21 can also be timed to move the filter plate frame 4 at regular intervals to achieve the effect of timed cleaning. After the device has been used for a long time, the brush bristles need to be tidied or replaced, and the filter screen 5 can also be removed from the bottom of the device for inspection, improving the practicality and service life of the device.
