Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device for building water supply and drainage. Background Art

[0002] After the building drainage is discharged, the water is filtered to purify the water quality. With the continuous advancement of technology, the filtering devices used in building water supply and drainage have also been improved to a certain extent, but there are still some shortcomings.

[0003] The utility model with publication number CN211394153U discloses a filtering device for building water supply and drainage. The filter screen inside the filter box is used to block the impurities in the water supply and drainage. At this time, the impurities will accumulate on the filter screen. Since a slag discharge port is provided on the left side of the filter box, after the water supply and drainage is discharged from the water inlet pipe, it passes through the filter screen and tilts to the lower right. The water supply and drainage will not flow out from the inside of the slag discharge port. Through the operation of the water pump, the water supply and drainage after the impurities are filtered out are discharged to the inside of the filter tank for the next filtering process. Since the impurities will accumulate on the filter screen, the rotating motor is driven to run at this time, so as to achieve the purpose of conveniently cleaning the residue. However, when the impurities accumulate, the purpose of thoroughly cleaning the residue cannot be achieved by the rotating motor, and the direct impact of water on the filter screen is not conducive to better achieving the effect of shock absorption and protection of the filter screen, and it is not convenient to speed up the filtration speed to prevent the residue from being blocked, resulting in the situation that the water cannot be filtered. In the Chinese patent application publication document with application number 202023062963.4, by designing relevant structures, the filtering device for water supply and drainage of the building can better clean up the residue, speed up the filtration speed, prevent the residue from clogging and causing the water to be unable to be filtered, and better achieve the effect of shock absorption and protection of the filter net.

[0004] However, the above scheme still has the following problems: the impurities cannot be cleaned during the filtration process, that is, the liquid filtration process and the impurity cleaning process cannot be carried out at the same time. When the impurities need to be cleaned, the liquid filtration process needs to be closed. Therefore, when the above device is in use, the filter device needs to be opened at regular intervals to clean the impurities. The process is cumbersome and also reduces the efficiency of liquid filtration.

[0005] Therefore, in view of the above problems, we propose a filtering device for building water supply and drainage. Utility Model Content

[0008] As a further description of the present invention: the number of the placing plates and the filter screens are both two groups, and the placing plates and the filter screens are distributed in an interval circular pattern inside the outer fixing ring.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The utility model is provided with a stirring structure and a filtering device. When in use, water flows into the filter housing through the water inlet hole. At this time, the servo motor is not started, and the stirring plate separates the two groups of filter screens and the placement plate. The water flowing into the water inlet hole is filtered through the filter screen and stored in the filter housing. When there are too many impurities on the filter screen that affect the filtering effect, the staff can start the servo motor at this time, and the driving shaft drives the connecting shaft to rotate through the first connecting flange and the second connecting flange, thereby driving the sleeve and the stirring plate to rotate. When the stirring plate rotates to separate the filter screen and the placement plate again, it can scrape the impurities on the surface of the filter screen onto the placement plate, and then collect the impurities through the groove, which can solve the problem that the current filter device for building water supply and drainage cannot filter when removing impurities, thereby improving the filtering efficiency of the filter device for building water supply and drainage.

[0025] In this embodiment, the stirring structure 3 includes a servo motor 301, which is fixedly mounted on the top of the filter upper cover plate 2, and a driving shaft 302 is fixedly mounted on the output end of the servo motor 301, and the servo motor 301 is connected to an external controller.

[0026] When used specifically: the servo motor 301 is connected to an external controller, can be turned on and off at a fixed time, and can provide stable power for the rotation of the stirring plate 307 .

[0027] In this embodiment, a first connection flange 303 is fixedly mounted on one end of the driving shaft 302 away from the servo motor 301 , and a second connection flange 304 is fixedly mounted on the bottom of the first connection flange 303 .

[0028] When used specifically, the first connecting flange 303 and the second connecting flange 304 can transmit the power after the servo motor 301 is started to the connecting shaft 305 , thereby driving the connecting shaft 305 to rotate.

The water flowing into the water inlet hole 6 is filtered through the filter screen 403 and stored in the filter housing 1. When there are too many impurities on the filter screen 403 that affect the filtering effect, the staff can start the servo motor 301 at this time, and the drive shaft 302 drives the connecting shaft 305 to rotate through the first connecting flange 303 and the second connecting flange 304, thereby driving the ring 306 and the stirring plate 307 to rotate.
