Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

Example 1

Please refer to Figure 1-4, which shows a stainless steel pipeline filter, including a treatment pipe 3. Existing: Chinese patent with publication number CN211411245U, which discloses a pipeline filter. This patent discloses a liquid inlet port, liquid outlet, sewage outlet, inner cavity and filter structure. The water inlet pipe 1, water outlet pipe 2 and treatment pipe 3 in this application document adopt the same technical means in the prior art. This technical means is here I won’t go into details one by one.

An inlet pipe 1 and an outlet pipe 2 are provided at both ends of the treatment pipe 3. The outer wall of the water inlet pipe 1 is fixedly connected to a backwash pipe 4. One end of the backwash pipe 4 away from the water inlet pipe 1 is fixedly connected to the outer wall of the outlet pipe 2. The outlet pipe A filter 5 for filtering impurities is provided inside the water inlet pipe 1. A mounting rod 7 is rotatably connected to the inside of the water inlet pipe 1 through a torsion spring, and a baffle 6 is fixedly connected to the outer wall of the mounting rod 7.

A flow guide assembly for controlling the flow direction of sewage is provided inside the backwash pipe 4 .

Please refer to Figures 1-4. In the figure, the flow guide assembly includes a rotating rod 9 and a rotating plate 10. The rotating rod 9 is rotatably installed inside the backwash pipe 4, and the rotating plate 10 is fixedly connected to the outer wall of the rotating rod 9.

Please refer to Figure 1-4. In the figure, there are multiple rotating rods 9. Two rotating rods 9 are arranged at both ends of the backwash pipe 4. One rotating rod 9 is arranged inside the outlet pipe 2. The number of rotating plates 10 is The number is consistent with the number of rotating rods 9.

In this embodiment: the water inlet pipe 1, the water outlet pipe 2, the treatment pipe 3 are connected with the inner cavity of the backwash pipe 4, and at the same time, one end of the backwash pipe 4 close to the water outlet pipe 2 is arranged in the filter 5 and the water outlet pipe 2. The rotating rod 9, the flow baffle 6 is set through the installation rod 7, so that the flow baffle 6 has the tendency to block the inner cavity of the water inlet pipe 1 in real time.

When it is necessary to treat sewage, rotate the rotating rod 9 in the backwash pipe 4 to make the rotating plate 10 block both ends of the backwash pipe 4, rotate the rotating rod 9 inside the water outlet pipe 2, open the inner cavity of the water outlet pipe 2, and discharge the sewage Introduced from the water inlet pipe 1, the sewage impacts the baffle 6, causing the baffle 6 to deflect, and then the sewage enters the inside of the treatment pipe 3 and impacts the filter 5, so that the impurities in the sewage are filtered by the filter 5 and remain in the treatment pipe. 3 interior.

When impurities adhere to the filter screen 5 and the filter screen 5 needs to be cleaned, rotate the rotating rod 9 and open the rotating plate 10 to connect the backwash pipe 4 with the inner cavity of the water inlet pipe 1 and the treatment pipe 3, and rotate the water outlet pipe 2 The rotating rod 9 inside causes the rotating plate 10 inside the water outlet pipe 2 to block the water outlet pipe 2, thereby realizing circulation between the water inlet pipe 1, the treatment pipe 3 and the backwash pipe 4.

Use clean water to be introduced into the inlet pipe 1. The clean water enters the inside of the backwash pipe 4 through the pipe, and then flows out from the outlet pipe 2. After being blocked by the rotating plate 10, the clean water impacts the filter screen 5, causing the impurities attached to the surface of the filter screen 5 to withstand the action of the clean water. The reverse flushing causes the impurities and clean water to fall inside the treatment pipe 3, thereby causing the impurities and clean water to flow out from the sewage pipe at the bottom of the treatment pipe 3 to clean the filter 5. At the same time, the baffle 6 withstands the impact of the clean water inside the treatment pipe 3. The baffle 6 is placed inside the water inlet pipe 1 to block the inner cavity of the water inlet pipe 1, so that the clean water entering from the direction of the water inlet pipe 1 can enter the inside of the backwash pipe 4 as much as possible, thereby improving the cleaning efficiency of the filter 5 with clean water.

Example 2

Please refer to FIGS. 1-4 . This embodiment further explains Embodiment 1. In the illustration, the side wall of the rotating plate 10 is in sliding contact with the inner wall of the backwash pipe 4 .

In this embodiment: the blocking efficiency of the rotating plate 10 when blocking the pipeline is improved.

Please refer to Figure 1-4. In the figure, the inner wall of the water inlet pipe 1 is fixedly connected to the limiting block 8, and the outer wall of the limiting block 8 rotates with the outer wall of the baffle 6.

In this embodiment, through the arrangement of the limiting block 8, the baffle plate 6 is less likely to deflect excessively when it is washed with clean water.

Please refer to Figure 1-4. In the figure, the bottom surface of the treatment pipe 3 is provided with a sewage outlet for sewage discharge. The sewage outlet is connected to an end cap 11 through internal and external threads.

In this embodiment, through the arrangement of the end cover 11, the inner cavity of the treatment pipe 3 is further sealed, thereby improving the circulation efficiency of sewage.
