Description

Technical Field

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

[0002] With the rapid development of social economy and urbanization, more and more high-rise buildings are built on construction sites. It is easy for more stones and garbage to appear in the drainage pipes of construction sites. Too many and too large stones and plastics can easily cause pipe blockage, affecting the normal circulation of water. In serious cases, it can cause water pipes to burst, causing certain economic losses. Therefore, a pipe filter device is needed to filter the drainage pipe, promote the normal circulation of water in the pipe, and make the water in the pipe cleaner.

[0003] After searching, the Chinese patent application number CN201921722855.X discloses a filtering structure for building water supply and drainage pipes. The existing drainage pipe filtering device is a vertically arranged filter net, which is not convenient for cleaning the filtered garbage. The following scheme is proposed, including a shell, a mud removal device, a filter frame, a water level sensor, an alarm and a shell top door; the shell is installed in the middle of the pipe, and a mud removal device is placed on the inner bottom of the shell. The mud removal device includes a bottom box, a first arc circle, a pull rope and a ring. The bottom box is a rectangular hollow structure. Two groups of first arc circles are installed at the bottom ends of the left and right side plates of the bottom box. The first arc circle is sleeved with a pull rope, and the top of the pull rope is sleeved with a ring. The utility model filters out garbage in the pipe water through the filter frame to prevent excessive garbage from clogging the pipe and affecting the normal circulation of water. The installation of two groups of filter frames can filter out garbage at the left and right ends of the pipe. A pull handle is installed at the top of the outer frame to facilitate the removal of garbage in the filter frame when cleaning it, thereby improving the convenience of operation.

[0004] Although the above patent can realize a simple filtering function, there are still the following shortcomings during use: with long-term use, it is necessary to manually clean the filtered impurities regularly. If the cleaning is not timely, it will cause blockage of the pipeline, affecting normal use. Automatic cleaning cannot be achieved, and the practicality is poor.

[0005] Therefore, there is an urgent need for a pipe interface filtering and cleaning device for building water supply and drainage to solve the above problems. Utility Model Content

[0026] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0027] like Figure 1-5As shown, the present embodiment proposes a filtering and cleaning device for a pipe interface for building water supply and drainage, comprising a pipe body 1, a mounting groove 11 is arranged inside the pipe body 1, a debris discharge bin 2 for discharging filtered debris is also arranged inside the pipe body 1, and further comprising:

[0028] The impurity discharge port 21 is provided on the bottom wall of the pipeline body 1, and the impurity discharge port 21 corresponds to the impurity discharge bin 2;

[0029] The filter component includes a sliding frame 3 slidably connected to the inner wall of the mounting groove 11, a first filter screen 31 fixedly connected to the inner wall of the sliding frame 3, a fixing rod 32 fixedly connected to the side wall of the sliding frame 3 and symmetrically distributed about the central axis of the first filter screen 31, and a fixing plate 33 fixedly connected to the outer wall of the fixing rod 32, and the fixing plate 33 is slidably connected to the pipeline body 1;

[0030] The blocking component is slidably connected to the impurity discharge port 21, and the blocking component cooperates with the filtering component. When the first filter screen 31 is blocked, the sliding frame 3 slides under the action of water pressure, and the blocking component is separated from the impurity discharge port 21 as the sliding frame 3 pushes the impurities. The water flow carries the impurities and is discharged from the impurity discharge port 21, thereby realizing automatic cleaning of the impurities, reducing the later maintenance cost, and improving the overall filtering effect.

[0031] like Figure 3-5 As shown, as a preferred embodiment, on the basis of the above method, further, the side wall of the sliding frame 3 is also fixedly connected to a support rod 34 symmetrically distributed about the central axis of the first filter screen 31, the support rod 34 cooperates with the blocking component, and the outer wall of the fixed rod 32 is also sleeved with a first elastic member 35, and the first elastic member 35 is located between the fixed plate 33 and the sliding frame 3.

[0032] like Figure 3-5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the inner wall of the impurity discharge bin 2 is also fixedly connected to a second filter screen 22, the inner wall of the pipeline body 1 is also fixedly connected to a limit stop rod 12 for limiting the sliding frame 3, and the pipeline body 1 is also provided with symmetrically arranged sliding grooves 13, the second filter screen 22 filters impurities and achieves the effect of pressure relief, and flushes the impurities filtered by the first filter screen 31 into the impurity discharge bin 2.

[0033] like Figure 2-5As shown, as a preferred embodiment, on the basis of the above method, further, the blocking component is slidably connected to the blocking plate 4 on the inner wall of the debris discharge port 21, a connecting rod 41 fixedly connected to the side wall of the blocking plate 4 and symmetrically distributed about the central axis of the blocking plate 4, and a second elastic member 42 sleeved on the outer wall of the connecting rod 41, and the end of the connecting rod 41 away from the blocking plate 4 passes through the sliding groove 13 and is fixedly connected with a support plate 43, and the support plate 43 cooperates with the support rod 34. When the debris discharge bin 2 is full of impurities and water cannot pass through, the internal pressure increases again and pushes the sliding frame 3 to slide again. When the sliding frame 3 slides, it drives the support rod 34 to gradually contact the support plate 43, and drives the support plate 43 and the connecting rod 41 to pull the blocking plate 4 to separate from the debris discharge port 21, and the high-pressure water flow carries the impurities and is discharged from the debris discharge port 21, thereby realizing automatic cleaning of impurities.

[0034] like Figure 1-2 As shown, as a preferred embodiment, on the basis of the above method, further, both ends of the pipeline body 1 are provided with connection interfaces 14, the bottom wall of the blocking plate 4 is provided with a pull rod 44, and a sealing gasket is also provided at the connection between the blocking plate 4 and the impurity discharge port 21.

[0035] Specifically, when the present building water supply and drainage pipe interface filtering and cleaning device is used: the water inlet pipe is connected to the pipe body 1 through the connection interface 14 near one end of the first filter screen 31, and the drain pipe is connected to the other end. After a long period of use, when the filter screen is blocked by impurities, the water flow cannot pass through, so that the internal pressure of the pipe body 1 increases, and the sliding frame 3 is pressed to slide. When the movement passes the opening position of the debris discharge bin 2, the water flows through the opening of the debris discharge bin 2 into the debris discharge bin 2, and is discharged after being filtered by the second filter screen 22, thereby reducing the internal pressure of the pipe body 1 and removing the impurities filtered by the first filter screen 31. Rushing to the impurity discharge bin 2, when the impurities are piled up inside the impurity discharge bin 2 and the water flow cannot pass through, the internal pressure increases again and pushes the sliding frame 3 to slide again. When the sliding frame 3 slides, it drives the support rod 34 to gradually contact the support plate 43, drives the support plate 43 and the connecting rod 41 to pull the sealing plate 4 to separate from the impurity discharge port 21, and the high-pressure water flow carries the impurities and is discharged from the impurity discharge port 21, thereby realizing automatic cleaning of the impurities, reducing the subsequent maintenance cost, and improving the overall filtering effect. After the impurities are discharged, under the action of the first elastic member 35 and the second elastic member 42, the sliding frame 3 and the sealing plate 4 are driven to reset.

[0036] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
