[0001] This utility model belongs to the field of filtration devices, specifically, it relates to a water supply treatment filtration device. Background Technology

[0002] In municipal engineering construction, water supply facilities are one of the important civil facilities.

[0003] Chinese patent CN220142701U discloses a municipal water supply treatment filtration device. The filter screen can isolate and filter large particulate impurities in the water. The U-shaped tube can prevent water from impacting the internal filter plate, and the U-shaped tube can also achieve sedimentation of impurities in the water. Valve body one and valve body two cooperate to open and close, so as to clean the U-shaped tube and filter screen. The air pipe is used to enhance the delivery pressure.

[0004] However, in the aforementioned municipal water supply treatment filtration device, although the filter plate can block and filter impurities, the filtered impurities move around on the bottom surface of the filter plate, which can easily affect the filtration of the filter plate and thus affect the water supply efficiency.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a water treatment filtration device.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A water treatment filtration device includes a filter box with a baffle inside. Multiple filtration mechanisms are arranged on one side of the baffle. Each filtration mechanism includes an arc-shaped filter plate arranged on one side of the baffle, a slag guide plate connected to the arc-shaped filter plate on the side away from the baffle, a scraper rotatably fitted in the slag guide plate, and a drive mechanism arranged on one side of the filter box for driving the scraper to rotate.

[0009] Optionally, the height of the end of the arc-shaped filter plate near the slag guide plate is lower than the height of its axis.

[0010] Optionally, the scraper has a U-shaped structure, with the outer side of the scraper fitting against the inner wall of the arc-shaped filter plate.

[0011] Optionally, the drive mechanism includes a drive shaft rotatably fitted inside the filter box, a servo motor located on one side of the filter box for driving the drive shaft to rotate, and a scraper fixed to the side of the drive shaft.

[0012] Optionally, the height of the upper part of the guide plate gradually increases from the end away from the arc-shaped filter plate to the end closer to the arc-shaped filter plate.

[0013] Optionally, a slag outlet corresponding to the slag guide plate is provided on one side of the filter box, and a slag outlet door is rotatably fitted inside the slag outlet.

[0014] Optionally, the upper side of the filter box is connected to an inlet pipe corresponding to the arc-shaped filter plate, one end of which is connected to an inlet pump, and the lower part of the filter box is connected to an outlet pipe, one end of which is connected to a booster pump.

[0015] Optionally, the baffle divides the filter box into a filtration zone and a water storage zone, and a one-way drain valve is connected to one side of the baffle.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0017] Water is discharged into the filter box and filtered sequentially through multiple arc-shaped filter plates. Then, the drive mechanism is activated to rotate the scraper. The scraper pushes the impurities filtered out from the inner wall of the arc-shaped filter plates. When the scraper rotates to the end of the arc-shaped filter plate near the guide plate, the scraper side tilts downward, which makes it easier for the impurities on the scraper side to slide onto the guide plate for temporary storage. This helps to reduce the impact of the filtered impurities on the filtration effect of the arc-shaped filter plates and reduce the impact on the water supply efficiency.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this embodiment provides a water treatment filtration device, including a filter box 1. The filter box 1 is provided with a baffle 2. Multiple filtration mechanisms 3 are provided on one side of the baffle 2. The filtration mechanism 3 includes an arc-shaped filter plate 301 provided on one side of the baffle 2, a slag guide plate 302 connected to the arc-shaped filter plate 301 away from the baffle 2, a scraper 303 rotatably fitted in the slag guide plate 302, and a drive mechanism 304 provided on one side of the filter box 1 for driving the scraper 303 to rotate. The diameter of the filter holes on the multiple arc-shaped filter plates 301 gradually decreases along the height direction of the filter box 1, which facilitates multi-stage filtration through the multiple arc-shaped filter plates 301.

[0029] Water is discharged into the filter box 1 and filtered sequentially by multiple arc-shaped filter plates 301. Then, the drive mechanism 304 is activated to drive the scraper 303 to rotate. The scraper 303 pushes the impurities filtered out from the inner wall of the arc-shaped filter plates 301. When the scraper 303 rotates to the end of the arc-shaped filter plate 301 close to the slag guide plate 302, the scraping side of the scraper 303 tilts downward, so that the impurities on the scraping side of the scraper 303 can slide down onto the slag guide plate 302 for temporary storage. This helps to reduce the impact of the filtered impurities on the filtration effect of the arc-shaped filter plate 301 and reduce the impact on the water supply efficiency.

[0030] Please see Figure 2 As shown, in this embodiment, the height of the arc-shaped filter plate 301 near the slag guide plate 302 is lower than its axial height, so that when the scraper 303 rotates to the end of the arc-shaped filter plate 301 near the slag guide plate 302, the scraping side of the scraper 303 is tilted downward, so that the impurities on the scraping side of the scraper 303 can slide down onto the slag guide plate 302 for temporary storage.

[0031] Please see Figure 2 As shown, the scraper 303 in this embodiment has a U-shaped plate structure. The outer side of the scraper 303 is attached to the inner wall of the arc-shaped filter plate 301, which makes it easier to reduce the volume of the scraper 303 and reduce the cost of the scraper 303.

[0032] Please see Figure 2-4 As shown, the drive mechanism 304 in this embodiment includes a drive shaft 3041 rotatably fitted inside the filter box 1, a servo motor 3042 located on one side of the filter box 1 for driving the drive shaft 3041 to rotate, and a scraper 303 fixed to the side of the drive shaft 3041, so that the servo motor 3042 can drive the drive shaft 3041 to drive the scraper 303 to rotate, and push the impurities filtered out by the inner wall of the arc-shaped filter plate 301 through the scraper 303.

[0033] Please see Figure 2 As shown, in this embodiment, the height of the upper side of the slag guide plate 302 gradually increases from the end away from the arc-shaped filter plate 301 to the end closer to the arc-shaped filter plate 301. The filter box 1 is provided with a slag outlet 4 corresponding to the slag guide plate 302 on one side. A slag outlet door 5 is rotatably fitted inside the slag outlet 4, which facilitates the discharge of impurities on the slag guide plate 302 along its upper inclined surface through the slag outlet 4, thereby improving the convenience of cleaning impurities on the slag guide plate 302.

[0034] Please see Figure 1-3 As shown, in this embodiment, the upper side of the filter box 1 is connected to an inlet pipe 6 corresponding to the arc-shaped filter plate 301. One end of the inlet pipe 6 is connected to an inlet pump 7. The lower part of the filter box 1 is connected to an outlet pipe 8. One end of the outlet pipe 8 is connected to a booster pump 9. The baffle 2 divides the filter box 1 into a filtration zone 10 and a water storage zone 11. One side of the baffle 2 is connected to a one-way drain valve 12, which facilitates the opening of the inlet pump 7 to discharge water into the filtration zone 10 of the filter box 1 through the inlet pipe 6. The water is filtered sequentially by multiple arc-shaped filter plates 301, and then discharged into the water storage zone 11 through the one-way drain valve 12. Then, it is pressurized and discharged through the outlet pipe 8 and the booster pump 9. By setting the one-way drain valve 12, the probability of backflow from the water storage zone 11 into the filtration zone 10 when the booster pump 9 is damaged, causing the inlet pump 7 to drain in reverse, is reduced.

[0035] Working principle: The inlet pump 7 is turned on, and water is discharged into the filtration zone 10 inside the filter box 1 through the inlet pipe 6. It is filtered sequentially by multiple arc-shaped filter plates 301, and then discharged into the storage zone 11 through the one-way drain valve 12. Afterwards, it is pressurized and discharged through the outlet pipe 8 and the booster pump 9. The servo motor 3042 is turned on, driving the transmission shaft 3041 to rotate the scraper 303. The scraper 303 pushes the impurities filtered from the inner wall of the arc-shaped filter plates 301. When the scraper 303 rotates to the end of the arc-shaped filter plate 301 near the guide plate 302, because the height of the end of the arc-shaped filter plate 301 near the guide plate 302 is lower than its axis... The scraper 303 is tilted downwards on the scraping side, which makes it easier for impurities on the scraping side of the scraper 303 to slide down to the slag guide plate 302 for temporary storage. This helps to reduce the impact of the filtered impurities on the filtration effect of the arc-shaped filter plate 301 and reduce the impact on the water supply efficiency. When it is necessary to clean the impurities temporarily stored on the slag guide plate 302, the slag outlet 4 is opened by rotating the slag outlet gate 5, and then the impurities temporarily stored on the slag guide plate 302 are cleaned. This facilitates the quick cleaning of the temporarily stored impurities. By setting a one-way drain valve 12, the probability of backflow from the water storage area 11 into the filter area 10 when the pressure pump 9 is damaged, causing the water inlet pump 7 to drain in reverse, is reduced.
